MedicalResearch.com Interview with: James Baggs, PhD Division of Healthcare Quality Promotion Centers for Disease Control and Prevention Atlanta, GA Medical Research: What is the background for this study? Dr. Baggs: The National Action Plan for Combating Antibiotic Resistance Bacteria calls for annual reporting of antibiotic use in inpatient settings as well as the identification of variations at the provider or patient level that can assist in developing interventions. Antibiotic use varies among hospitals, but some portion of that variability is related to the type of patients admitted to the hospital and other hospital characteristics. We evaluated factors in a large cohort of US hospitals that may account for inter-facility variability in antibiotic use, so that we can more appropriately monitor antibiotic use in hospitals. Medical Research: What are the main findings? Dr. Baggs: We utilized data from the Truven Health MarketScan Hospital Drug Database (HDD), which contains detailed administrative records, including inpatient drug utilization data based on billing records, for all patients discharged from a convenience sample of over 500 US hospitals. We retrospectively estimated days of therapy (DOT)/1,000 patient days (PDs) by year from 2006-2012, and created a multivariable model that adjusts for hospital-specific location of antibiotic use (ICU vs. other), average patient age, average patient co-morbidity score, number of hospital beds, teaching status, urban or rural location, proportion of discharges with a surgical diagnosis related code, case mix index, and proportion of patient days with an infectious disease primary ICD-9-CM discharge code. We observed that DOT varied significantly between hospitals; the 10th to 90th percentile values for hospital days of therapy ranged from 546 to 998/1,000 PDs. The variables included in our model accounted for 47-53% of the inter-facility variability, depending on year. However, nearly all of this variability was explained by two predictors: proportion of PDs with an infectious disease diagnosis code and hospital location (ICU vs. other).  (more…)

Wencui Han PhD Assistant Professor Business Administration University of Illinois at Urbana ChampaignMedicalResearch.com Interview with: Wencui Han PhD Assistant Professor Business Administration University of Illinois at Urbana Champaign Medical Research: What is the background for this study? What are the main findings? Dr. Han: Well-designed disease registries integrate a variety of information, including patient demographics, laboratory results, pharmacy data, and comorbidity data, to serve a variety of functions outside the clinical encounter. However, the adoption of disease registries by healthcare organizations is associated with significant direct and indirect costs. The impacts of using disease registries that meet meaningful use (MU) requirements in improving health outcomes and creating cost savings are understudied. This study examines the impact of using a registry for patient reminders and for improvement of the quality of care, hospital utilization, and cost saving. The results suggest that the use of diabetes registries meeting Meaningful Use core objectives is associated with higher completion or recommended lab tests and a lower hospital utilization rate for patients with type 2 diabetes.

MedicalResearch.com Interview with: Dr Daniel Boden Emergency Medicine Consultant Derby Hospitals NHS Foundation Trust Medical Research: What is the background for this study? What are the main findings? Dr. Boden: The overall objective was to evaluate whether there is an association between an intervention to reduce medical bed occupancy and both performance on the 4-hour target and hospital mortality. We undertook a before-and-after study in Derby teaching Hospitals NHS Foundation Trust (a large UK District General Hospital) over a 32 month period. A range of interventions were undertaken to reduce medical bed occupancy within the Trust. Performance on the four-hour target and hospital mortality (HSMR, SHMI and Crude Mortality) were compared before, and after, intervention. Daily data on medical bed occupancy and percentage of patients meeting the four-hour target was collected from hospital records. Segmented regression analysis of interrupted time-series method was used to estimate the changes in levels and trends in average medical bed occupancy, monthly performance on the target and monthly mortality measures (HSMR, SHMI and crude mortality) that followed the intervention. Medical Research: What are the main findings? Dr. Boden:
  • Mean medical bed occupancy decreased significantly from 93.7% to 90.2% (p=0.02).
  • The trend change in 95% target performance, when comparing pre- and post-intervention, revealed a significant improvement (p=0.019). The intervention was associated with a mean reduction in all markers of mortality (range 4.5% - 4.8%). SHMI (p=0.02) and Crude Mortality (p=0.018) showed significant trend changes after intervention.
  • Our conclusion is that lowering medical bed occupancy is associated with reduced patient mortality and improved ability of the acute Trust to achieve the 95% four hour target. Whole system transformation is required to create lower average medical bed occupancy.

What are the main findings? Dr. Min Suk Rhee: In December 2013, the US FDA (United States Food and Drug Administration) proposed an amendment that manufacturers of antibacterial hand soaps intended for use with water must demonstrate that they are safer and more effective than plain soap. As triclosan is the most common active antiseptic ingredient used in soap and its potential risk remains controversial, we investigated the effectiveness of antibacterial soap containing triclosan 0.3% from in vitro and in vivo experiment. The main finding of this study is that presence of antiseptic ingredients (in this case, triclosan) in soap does not always guarantee higher antimicrobial efficacy during hand washing. (more…)

J. Michael McWilliams MD, PhD Associate Professor andMedicalResearch.com Interview with: J. Michael McWilliams MD, PhD Associate Professor and Dr. Michael Barnett MD Researcher and General Medicine Fellow Dept. of Health Care Policy Harvard Medical School Boston MADr. Michael Barnett MD Researcher and General Medicine Fellow Dept. of Health Care Policy Harvard Medical School Boston MA Medical Research: What is the background for this study? Response: The financial impact of Medicare’s Hospital Readmissions Reduction Program on hospitals is growing.  In this year’s round of penalties, nearly 2,600 hospitals were collectively fined $420 million for excess readmissions. There has been concern that the risk-adjustment methods used by Medicare to calculate a hospital’s expected readmission rate is inadequate, meaning that hospitals disproportionately serving sicker and more disadvantaged patients are being penalized because of the populations they serve rather than their quality of care.  Specifically, Medicare accounts only for some diagnoses, age and sex but no other clinical or social characteristics of patients admitted to the hospital. No study to date has examined the impact adjusting for a comprehensive set of clinical and social factors on differences in readmission rates between hospitals. We did this by using detailed survey data from the Health and Retirement Study linked to information on admissions and readmissions in survey participants’ Medicare claims data.  We then compared differences in readmission rates between patients admitted to hospitals in the highest vs. lowest quintile of publicly reported readmission rates, before vs. after adjusting for a rich set of patient characteristics.  These included self-reported health, functional status, cognition, depressive symptoms, household income and assets, race and ethnicity, educational attainment, and social supports. Medical Research: What are the main findings? Response: Our two most important findings were: 1) Patients admitted to hospitals with higher readmission rates are sicker and more socially disadvantaged in a variety of ways than patients admitted to hospitals with lower readmission rates. 2) After adjusting for all measurable patient factors that are not accounted for in standard Medicare adjustments, the difference in readmission rates between hospitals with high vs. low readmission rates fell by nearly 50%.

Megan Colleen McHugh, PhD Research Assistant Professor Center for Healthcare Studies Institute for Public Health and Medicine and Emergency Medicine Northwestern UniversityMedicalResearch.com Interview with: Megan Colleen McHugh, PhD Research Assistant Professor Center for Healthcare Studies Feinberg Institute for Public Health and Medicine and Emergency Medicine Northwestern University   Medical Research: What is the background for this study? What are the main findings? Dr. McHugh: There have been many large efforts to improve the delivery of health care in the U.S., for example, the Robert Wood Johnson Foundation’s Aligning Forces for Quality Program and the Institute for Healthcare Improvement’s 100,000 Lives Campaign.  One of the challenges to understanding whether these programs work is that the intervention “dose” – the quality and quantity of the intervention – often varies across different participating sites. As evaluators of multi-site quality improvement programs, we want to better understand how to measure the dose of a quality improvement intervention at participating sites.  We identified four different approaches to measuring dose.  These approaches resulted in different conclusions about which sites are “low dose” and “high dose” intervention sites. Medical Research: What should clinicians and patients take away from your report? Dr. McHugh: The main audience for this paper is program evaluators.  They should take away the following: 1) Variation in dose scores across intervention sites suggests that dose may be a contributor to the effectiveness of a quality improvement intervention. 2) It is feasible to measure the dose of a quality improvement intervention, but measuring QI dose presents many challenges, including subjective decisions about which approach to measurement to use and the need for extensive data collection.

Dr. Ansar Hassan MD PhD Department of Cardiac Surgery New Brunswick Heart Centre Saint John Regional Hospital Saint John, New BrunswicMedicalResearch.com Interview with: Dr. Ansar Hassan MD PhD Department of Cardiac Surgery New Brunswick Heart Centre Saint John Regional Hospital Saint John, New Brunswick Medical Research: What is the background for this study? What are the main findings? Dr. Hassan: For years, geographic place of residence and one’s proximity to a tertiary care center has been identified as a predictor for access to care.   Little is known regarding the effect of geography on patient outcomes.   The purpose of this study was to explore the relationship between geography and in-hospital / 30-day outcomes among patients undergoing cardiac surgery.  What we found was that despite there being no relationship between geography and in-hospital outcomes, those who lived further away from hospital clearly had worse 30-day outcomes. Medical Research: What should clinicians and patients take away from your report? Dr. Hassan: While patients from a differing geographic places of residence appear to have similar in-hospital outcomes following cardiac surgery, their clinical courses following discharge from hospital differ considerably.   Clinicians and patients need to realize that where one lives is tremendously important as it relates to his or her health and that particular attention needs to be paid to cardiac surgery patients who live further away from their tertiary care center, especially within the first 30 days following surgery.

MedicalResearch.com Interview with: Jill A. Marsteller, PhD, MPP Department of Health Policy and Management, Johns Hopkins Bloomberg School of Public Health Baltimore, Maryland and Juan A. Sanchez, MD, MPA, FACS, FACC Associate Professor of Surgery Associate Faculty, Armstrong Institute for Patient Safety and Quality Johns Hopkins Medicine Medical Research: What is the background for this study? What are the main findings? Response: The culture of healthcare organizations with regards to safety has an impact on patient outcomes.  A strong culture serves as a platform for preventing medical errors. This study examines the culture of safety along several dimensions in cardiac surgical teams and compares this data to surgery of all types using a large database. In our study, cardiac surgery teams scored highest in teamwork and lowest in non-punitive responses to error.  In addition, there was substantial variation on safety climate perception across team roles. For example, surgeons and support staff had higher perceptions of a safety climate than other team members. Compared to all types of surgery teams, cardiac surgery teams scored higher in overall perceptions of safety except for anesthesiologists who reported lower scores on communication about errors and communication openness.

What are the main findings? Dr. Mermel: Arterial catheters are an under recognized source of hospital-associated bloodstream infection. As a result, arterial catheter infection prevention strategies are less well studied than with central lines.  We did a national survey and our findings reaffirmed the fact that physicians using these catheters underestimate the risk of infection.  Additionally and not surprisingly, infection prevention strategies are variable particularly concerning barrier precautions at insertion. Medical Research: What should clinicians and patients take away from your report? Dr. Mermel: Arterial catheters can cause catheter-related bloodstream infections.  These devices should be aseptically inserted and managed post-insertion and removed as soon as no longer required for patient care.  We are also in need of better studies to clearly delineate the ideal infection prevention strategies with these catheters based on our understanding of the pathogenesis of such infections.  (more…)

Alicia A. Bergman, Ph.D. Research Health Scientist VA Greater Los Angeles Healthcare System Center for the Study of Healthcare Innovation, Implementation & Policy North Hills, CA 91343MedicalResearch.com Interview with: Alicia A. Bergman, Ph.D. Research Health Scientist VA Greater Los Angeles Healthcare System Center for the Study of Healthcare Innovation, Implementation & Policy North Hills, CA 91343  Medical Research: What is the background for this study? What are the main findings? Dr. Bergman: The impetus for this study comes from several sources but most notably the IOM report of 2002 entitled, Crossing the Quality Chasm in which the IOM estimated that between 44,000 and 98,000 lives are lost each year due to preventable medical errors in the hospital.  The IOM further reported that 80% of all adverse outcomes in the hospital can be traced back to breakdowns in communication during handoffs and transfers of care.  A 2005 study by our VA research team found that only 7% of medical schools in the US teach the handoff as part of the formal curriculum. As such, handoffs represent a vulnerable gap in the quality and safety of patient care. We were interested to know how end of shift handoffs in medicine, nursing, and surgery were enacted and audio and videotaped them in a single VA hospital. We found that there was a great deal of variation in how the handoffs were conducted and similar variations in the ways in which language was used to characterize technical and interpersonal aspects of care. We were especially interested in what we term “anticipatory management communication” and its functions during handoffs. While much technical information can easily be conveyed in the electronic medical record, some types of psychological or social information that are more informal in nature, such as “Mr. Smith’s been our problem child today,” do not lend themselves to being transmitted in the electronic medical record. However, such ‘heads up’ information and communication is often critical to understanding a patient’s context, course, and outcome of care. We also found that indirect anticipatory management communication was used among all dyads but more commonly among nurse dyads, with instructions and tasks implied and often inferential. We conclude that contextually sensitive information about anticipated events is best communicated directly (and ideally face-to-face), and that talk-backs and more explicit use of language can improve handoff quality, making them safer for patients.

Jason H. Wasfy, MD Assistant Medical Director Massachusetts General Physicians Organization Massachusetts General Hospital MedicalResearch.com Interview with: Jason H. Wasfy, MD Assistant Medical Director Massachusetts General Physicians Organization Massachusetts General Hospital   Medical Research: What is the background for this study? What are the main findings? Dr. Wasfy: Hospital readmission after angioplasty (heart stents) is very common in the United States and is associated with poorer patient outcomes and substantial health care costs.  We can predict which patients will get readmitted, but only with moderate accuracy.  Analyzing the electronic medical records of large health care systems may provide clues about how to predict readmissions more accurately. Medical Research: What should clinicians and patients take away from your report? Dr. Wasfy: Patients who are anxious or have visited the emergency department frequently before the procedure may be at higher risk of readmission.  For those patients, reassurance and support may help them stay out of the hospital.  This has the potential to improve health outcomes after angioplasty and improve value in cardiology care generally.  High quality care for patients with coronary artery disease involves not only procedures and medicines, but also creating a support system for patients to cope with their disease.

MedicalResearch.com Interview with: Kevin Heslin, Ph.D., Staff Service Fellow, Center for Delivery, Organization and Markets, Agency for Healthcare Research and Quality Medical Research: What is the background for this study? Dr. Heslin: Previous trends in inpatient mortality suggest that rates have been decreasing for acute myocardial infarction (AMI), congestive heart failure (CHF), stroke, and pneumonia (Hines et al., 2010; Stepanova et al., 2013).  Continued study of these trends can help researchers and policymakers assess the impact of health care quality efforts.  Further, examining trends across patient and hospital subgroups may inform strategies for addressing disparities in health care quality by identifying groups that are leading and lagging in improvement. Medical Research: What is the background for this study Dr. Heslin: From 2002 to 2012, inpatient mortality decreased among patients admitted to U.S. hospitals for pneumonia (45 percent decrease, from 65.0 to 35.8 deaths per 1,000 admissions), AMI (41 percent decrease, from 94.0 to 55.9 deaths per 1,000 admissions), CHF (29 percent decrease, from 44.4 to 31.4 deaths per 1,000 admissions), and stroke (27 percent decrease, from 112.6 to 82.6 deaths per 1,000 admissions).  The inpatient mortality rate for all four conditions decreased among both younger and older patients, and among men and women.

MedicalResearch.com Interview with: Alisa Khan, MD Pediatric hospitalist Boston Children's Hospital and Instructor of Pediatrics Harvard Medical School Medical Research: What is the background for this study? Dr. Khan: Patients can be readmitted to the same hospital they were discharged from or to a different hospital.  In adults, readmissions to different hospitals make up about 20% of all readmissions.  We don’t know a lot about how often different-hospital readmissions happen in children. Insurance companies know hospitals’ true readmission rates (which include when a hospital’s patients are readmitted to the same hospital and when they are readmitted to a different hospital).  However, hospitals don’t know their true readmission rates since they don’t have access to the full information that insurance companies have. If hospitals don’t know their true rates, they may think they are doing better at preventing readmissions than they really (for instance, if all their discharged patients are simply being readmitted to a different hospital).  Hospitals may also draw incorrect conclusions when they compare themselves to one another (like through benchmarking), and may not be able to predict whether they will be subject to penalties by insurers for having excessively high readmission rates. Medical Research: What are the main findings? Dr. Khan: We found that about 1 in 7 pediatric readmissions in New York over a 5-year period were to a different hospital than the hospital the patient was discharged from.   The percentage of different-hospital readmissions varied by hospital and patient characteristics.  Patients who were admitted to non-children’s hospitals, lower-volume hospitals, or urban hospitals had a higher chance of being readmitted to a different hospital, as did patients who were younger, white, privately insured, or who had certain chronic conditions (like mental health, neurologic, and circulatory conditions). We also found a lot of variability in how much individual hospitals would underestimate their true readmission rates if they only used this incomplete same-hospital readmission info.  Some hospitals would underestimate their true readmission rates by only 0.6 relative percentage points while others would underestimate them by 68 points.

MedicalResearch.com Interview with: Raymond Osarogiagbon MD, FACP Thoracic Oncology Research Group Baptist Cancer Center Memphis, Tennessee MedicalResearch.com Interview with: Raymond Osarogiagbon MD, FACP Thoracic Oncology Research Group Baptist Cancer Center Memphis, Tennessee

Medical Research: What is the background for this study? What are the main findings? Dr. Osarogiagbon: Lung cancer care is complicated, but can be broken down into 5 steps: x-ray detection, biopsy, x-ray tests of cancer spread (the ‘stage’), biopsy of suspicious areas where cancer may have spread, and treatment. Looking only at patients who had surgery for a suspected lung cancer, we worked backwards to see how their care went through the key steps and how long it took. We found that patients often skip some of the crucial steps. For example, 22% did not have a staging PET/CT scan, 88% did not have an invasive staging test. Only 10% had the recommended combination of 3 staging tests leading up to surgery: a CT scan, PET/CT scan, and invasive staging test. It took a month and a half to more than 6 months for the middle half of patients to go from first abnormal x-ray sign of possible lung cancer to surgery. (more…)

Response: Clinical performance measures – quality indicators used to evaluate and motivate health care providers' performance – play a central role right now in efforts to improve quality in U.S. health care. But their potential to influence care on a wide scale has some worried about unintended effects. In particular, there’s been growing concern that if performance measures focus disproportionately on underuse of care – that is, measuring whether enough care is being provided – they risk leading to unexpected consequences.   Specifically, if incentives tend to reward clinicians for doing more without attention to whether they do too much – this could inadvertently contribute to the problem of excessive care, or overuse. Medical Research: What are the main findings? Response: We thought it was important to look at what that balance is – between measures of underuse and measures of overuse – in outpatient practice.   We looked at 16 major national collections of performance measures and essentially counted measures targeting underuse (‘Did the clinician do enough?’) versus overuse (‘Did the clinician do too much?’). We found that over 90 percent of 521 outpatient measures targeted underuse, while a mere 7 percent of outpatient measures addressed overuse – in fact nearly half of the collections contained no overuse measures at all.

Helle Søholm, MD, PhDDepartment of Cardiology Copenhagen University Hospital Rigshospitalet Denmark MedicalResearch.com Interview with: Helle Søholm, MD, PhD Department of Cardiology Copenhagen University Hospital Rigshospitalet Denmark Medical Research: What is the background for this study? Dr. Søholm: The background of the current study is that previous studies have found higher survival rates after out-of-hospital cardiac arrest and admission to tertiary heart centres for post-resuscitaton care compared with nontertiary hospitals, however the reasons for this difference has only been speculative. The aim of the study was to examine the level-of post-resuscitation care at tertiary heart centers compared with nontertiary hospitals and to associate this with outcome. Only patients without ST-segment elevation myocardial infarction was examined to avoid referral bias. Medical Research: What are the main findings? Dr. Søholm: The main findings of the study of 1.078 patients was that the survival in patients admitted to tertiary heart centers was significantly higher compared with survival in patients admitted to nontertiary hospitals even after adjustment for known risk markers including pre-arrest co-morbidity. We found that the adjusted odds of predefined markers of level-of-care differed in both the acute phase after admission, during the intensive care admission and in the workup prior to hospital discharge. The odds of admission to an intensive care unit was 1.8 for patients admitted to a tertiary heart centre. During the intensive care admission the odds of a temporay pacemaker was 6.4, use of vasoactive agents 1.5, acute and late coronary angiography was 10 and 3.8 respectively, neurophysiological examination 1.8, brain computed tomography 1.9, whereas no difference in the odds of therapeutic hypothermia was found. Prior to hospital discharge the odds of a consultation by a cardiologist was 8.6, having an echocardiography was 2.9, and survivors more often had an implantable cardioverter defibrillator implanted (odds 2.1) as compared with patients admitted to nontertiary hospitals.

Cameron M.D. Professor of Alimentary Tract Diseases Chief, Division of Surgical Oncology Program Director, Surgical Oncology Fellowship Director, Johns Hopkins Medicine Liver Tumor Center Multi-Disciplinary Clinic Johns Hopkins Hospital Baltimore, MD 21287MedicalResearch.com Interview with: Timothy M. Pawlik, MD, MPH, MTS, PhD, FACS, FRACS (Hon.) Professor of Surgery and Oncology John L. Cameron M.D. Professor of Alimentary Tract Diseases Chief, Division of Surgical Oncology Program Director, Surgical Oncology Fellowship Director, Johns Hopkins Medicine Liver Tumor Center Multi-Disciplinary Clinic Johns Hopkins Hospital Baltimore, MD 21287 MedicalResearch: What is the background for this study? What are the main findings? Dr. Pawlik: In 2012, the Centers for Medicare and Medicaid Services (CMS) introduced the Hospital Readmission Reduction Program (HRRP) whereby hospitals with higher than expected 30-day readmission incur financial penalties. Initially proposed to target readmissions following acute myocardial infarction, pneumonia and congestive heart failure, the program has since expanded to encompass knee and hip replacement surgery with the inclusion of additional surgical procedures anticipated in the near future. Although initial results from the Hospital Readmission Reduction Program have been promising, several concerns have been raised regarding potential limitations in methodological approach; specifically in the ability to adequately risk-adjust and account for variations in patient, provider and disease. As a consequence, many fear that the Hospital Readmission Reduction Program may disproportionately penalize safety-net hospitals as well as hospitals caring for “sicker” and more vulnerable populations. In the current study we sought to investigate factors associated with the variability in 30-day readmission among a cohort of 22,559 patients discharged following a major surgical procedure at the Johns Hopkins Hospital between 2009 and 2013. Overall, 30-day readmission was noted to be 13.2% varying from 2.1% to 24.8% by surgical specialty / procedure and from 2.1% to 32.9% by surgeon. Non-modifiable patient specific factors such as preoperative comorbidity, insurance status and race / ethnicity, were found to be most predictive of 30-day readmission as well as postoperative factors such as complications and length of stay both of which may also be influenced by preoperative comorbidity. Overall, we noted that 2.8% of the variation in 30-day readmission was attributed to provider-specific factors, 14.5% of the variability was due differences in surgical specialty / procedure while over 84% of the variability in 30-day readmission remained unaccounted for due to non-modifiable patient-specific factors.

MedicalResearch.com Interview with: Philip G. Cotterill PhD Centers for Medicare & Medicaid Services Baltimore, MD Medical Research: What is the background for this study? What are the main findings? Dr. Cotterill: Chest pain is one of those elusive complaints where patients can seem initially low-risk based on symptoms or risk factors, and subsequently have an acute myocardial infarction (AMI) or die in a short period of time. Using combinations of history and physical examination findings to discriminate patients with serious causes of chest pain is often not possible. In our study, we demonstrated wide variation in the decision to hospitalize Medicare beneficiaries with chest pain – nearly two fold between the lowest (38%) and highest (81%) quintile of hospitals – and that patients treated in hospitals with higher admission rates for chest pain are less likely to have an acute myocardial infarction within 30-days of the index event and less likely to die. While the findings were statistically significant – differences in outcomes were small: 4 fewer AMIs and 3 fewer deaths per 1,000 patients comparing the highest and lowest admission quintiles. Stated differently, these numbers suggest that if low admitting hospitals were to behave more like high admitting hospitals, 250 patients would need to be admitted to prevent one AMI and 333 cases to prevent one death.

Riyaz Bashir MD, FACC, RVTProfessor of Medicine Director, Vascular and Endovascular Medicine Department of Medicine Division of Cardiovascular Diseases Temple University Hospital Philadelphia, PA 19140MedicalResearch.com Interview with: Riyaz Bashir MD, FACC, RVT Professor of Medicine Director, Vascular and Endovascular Medicine Department of Medicine Division of Cardiovascular Diseases Temple University Hospital Philadelphia, PA 19140 Medical Research: What is the background for this study? Dr. Bashir: Catheter-based thrombus removal also known as Catheter Directed Thrombolysis (CDT) is a minimally invasive therapeutic intervention that has evolved over the past two decades to reduce the incidence of post thrombotic syndrome (PTS), a very frequent and disabling complication of proximal deep vein thrombosis (DVT). Catheter-based thrombus removal has been shown to reduce this lifestyle limiting complication of DVT and as a result we have observed a significant increase in the utilization rates of CDT across United States. Recent nationwide observational data suggests that higher adverse events such as intracranial hemorrhage rates and need for blood transfusions are seen with CDT use. Nonetheless specific reasons for these findings have not been explored prior to this study. Thread veins, also known as spider veins, are small veins which can appear on your face, thighs or calves and are an issue that many patients want help with. However, they are a cosmetic issue rather than a medical problem. People who suffer from the spider veins often feel that they affect their appearance and confidence and question why do we get thread veins? Medical Research: What are the main findings? Dr. Bashir: This study showed a significant inverse relationship between the institutional Catheter-based thrombus removal volumes and safety outcomes like death and intracranial hemorrhage. The institutions with higher volume of CDT cases annually (greater than or equal to 6 cases) were associated with lower in-hospital mortality rates and lower intracranial hemorrhage rates as compared to institutions, which performed less than 6 cases annually. This study also showed that at high volume institutions there was no difference in terms of death or intracranial bleeding rates between CDT plus anticoagulation versus anticoagulation alone. (more…)

We added health research researchers from UCLA and USC, and shifted the focus of the group from logistical issues to quality improvement. As a first project, our hospitals wanted to know if there was any variation in how traumatic brain injury patients are cared for across the county. Traumatic brain injury accounts for over 1/3 of all injury-related deaths in the U.S. and is the number one reason for ambulance transport to a trauma center in LA County. When we looked at the data, we found widespread variation in both how these patients were cared for at different hospitals and what happened to them as a result of that care. After adjusting for important differences in patient mix, we found that mortality rates varied by hospital from roughly 25% to 55%. As we tried to explain this variation, we looked into how often hospitals complied with two evidence-based guidelines from the Brain Trauma Foundation, hoping that we could eventually develop an intervention to boost compliance with these recommended care practices. While compliance rates varied even more widely than mortality—from 10 to 65% for intracranial pressure monitoring and 7 to 76% for craniotomy—they did not appear to be associated with risk-adjusted mortality rates. Put simply, we found no connection between how often hospitals complied with the guidelines and how likely their patients were to survive. (more…)

Dr Scot Garg FRCP PhD (Hons) FESC Cardiology Department, Royal Blackburn Hospital United KingdomMedicalResearch.com Interview with: Dr Scot Garg FRCP PhD (Hons) FESC Cardiology Department, Royal Blackburn Hospital United Kingdom Medical Research: What is the background for this study? Dr. Garg: In contrast to other countries, in particular the United States, the UK has seen a vast expansion in the number of PCI centres operating without on-site surgical support. Part of the reason for this is that outcome data from these centres are from modest populations at short-term follow-up; consequently the ACC/AHA have failed to give delivery of PCI in centres without surgical back-up a strong endorsement. The study was ultimately driven therefore to show whether any differences existed in mortality between patients having PCI in centres with- and without surgical support at long-term follow-up in large unselected population cohort. Medical Research: What are the main findings? Dr. Garg: The study included the largest population of patients treated in centres without off-site surgical support (n=119,036) and main findings were that following multi-variate adjustment there were no differences in mortality for patients treated at centres with- or without surgical support at 30-days, 1-year or 5-year follow-up irrespective of whether patients were treated for stable angina, NSTEMI or STEMI. Furthermore, similar results were seen in a sensitivity analysis of a propensity matched cohort of 74,001 patients. (more…)

Judy A. Tjoe, MD, FACS Breast Oncology Surgeon Aurora Health Care Milwaukee, WIMedicalResearch.com Interview with: Judy A. Tjoe, MD, FACS Breast Oncology Surgeon Aurora Health Care Milwaukee, WI Medical Research: What is the background for this study? What are the main findings? Dr. Tjoe: Numerous national health organizations have confirmed minimally invasive breast biopsy (MIBB), which uses a percutaneous core needle as opposed to open surgical techniques, as the biopsy procedure of choice when a patient’s diagnostic test reveals a breast lesion suggestive of malignancy. Unfortunately, despite the overwhelming evidence supporting use of MIBB, open breast biopsy rates in the United States remain as high as 24-39%. Our study was designed to determine if measuring individual practice patterns and providing subsequent feedback to surgeons across a large, multihospital healthcare system would improve their adherence to the quality metric of using minimally invasive breast biopsy to diagnose indeterminate breast lesions. We found that the proportion of studied surgeons (n=46) appropriately adhering to the MIBB quality metric in every instance (i.e. those who achieved 100% adherence) significantly improved from 80.4% to 95.7% (p=0.0196) after receiving feedback on not only their own practice patterns, but those of their blinded peers. As might be expected, the handful of breast-dedicated surgeons (n=4) who cared for nearly half of the analyzed patient population achieved perfect adherence throughout the study, but interestingly, the gains made in total adherence were driven by the general surgeons (n=42), showing that the study’s direct educational efforts were effective in changing practice patterns for the better. These efforts included sending letters describing adherence to the quality metric to individual surgeons and organizational leadership. (more…)

What are the main findings? Dr. Huang: Residents are medical school graduates who are in training programs working alongside and under supervision of more senior physicians, known as attendings. Patients are sometimes wary of having residents assist in their operations, but an analysis of 16,098 brain and spine surgeries performed across the United States finds that resident participation does not raise patient risks for postoperative complications or death.

Ann Scheck McAlearney, Sc.D., M.S. Professor, Family Medicine Vice Chair for Research, Department of Family Medicine College of Medicine Ohio State University Columbus, OhioMedicalResearch.com Interview with: Ann Scheck McAlearney, Sc.D., M.S. Professor, Family Medicine Vice Chair for Research, Department of Family Medicine College of Medicine Ohio State University Columbus, Ohio MedicalResearch: What is the background for this study? What are the main findings? Dr. McAlearney: In this study, we sought to explore the potential role high-performance work practices (HPWPs) may play in explaining differences in the success of central line-associated blood stream infection (CLABSI) reduction efforts involving otherwise similar organizations and approaches. We analyzed data from 194 key informant interviews across eight hospitals participating in the federally funded ‘‘On the CUSP: Stop BSI’’ initiative. We found evidence that at sites more successful at reducing central line-associated blood stream infection, HPWPs facilitated the adoption and consistent application of practices known to prevent CLABSIs; these HPWPs were virtually absent at lower performing sites. In this paper we present examples of management practices and illustrative quotes categorized into four HPWP subsystems: (a) staff engagement, (b) staff acquisition/development, c) frontline empowerment, and (d) leadership alignment/development.

Laila Cure, Ph.D. Assistant Professor Dept. of Industrial and Manufacturing Engineering Wichita State UniversityMedicalResearch.com Interview with: Laila Cure, Ph.D. Assistant Professor Dept. of Industrial and Manufacturing Engineering Wichita State University Medical Research: What is the background for this study? What are the main findings? Response: It is widely known that healthcare work, particularly inpatient care work, is mostly knowledge-based. Healthcare workers are constantly assessing the clinical state of their patients and making decisions that affect their workflow. This type of work is difficult to study and organize as a whole using traditional work design techniques, which are mostly designed for routine, repetitive work. Nevertheless, there are components of inpatient work that can be improved using basic workstation design principles. Hand hygiene is one of them. Hand hygiene is still the single most important intervention to prevent infection in hospitals. Guidelines state that health care workers should clean their hands before touching a patient, before an aseptic procedure, after body fluid exposure, after touching a patient, after touching patient surroundings. Hand sanitizer dispensers are practical resources to support hand hygiene because they can be placed almost anywhere throughout hospital units. This study aimed at determining whether “good” placement of sanitizer dispensers correlates with compliance of staff in using the sanitizer. “Good placement” was defined in terms of usability characteristics extracted from hand hygiene literature recommendations. Of the usability characteristics included in the study, visibility and accessibility had some statistical influence on improving compliance. (more…)

MedicalResearch.com Interview with: Stephen M. Shortell, PhD, MPH, MBA Blue Cross of California Distinguished Professor of Health Policy and Management and Director, Center for Healthcare Organizational and Innovation Research (CHOIR) School of Public Health UC-Berkeley Medical Research: What is the background for this study? What are the main findings? Dr. Shortell: To meet quality and expenditure targets, Accountable Care Organization (ACOs) need to change how care is delivered to patients to reduce preventable hospitalizations, readmissions, emergency department visits, and unnecessary tests. To do this they need to increase their engagement with patients and patient families. With support from the Gordon and Betty Moore Foundation, we undertook the study to assess the extent to which ACOs are engaging their patients and patient families and to identify some of the barriers and facilitators of such engagement. We did a survey of 101 ACOs, in-depth phone interviews with eleven ACOs and two on site visits. Among our key findings are: 1) There are some "early adopters" of patient engagement activities with, for example, respondents reporting an average of 62 percent of primary care physicians working with patients/families to set treatment goals and 61 percent of high risk chronic illness patients participating in formal care transition programs; but 2) Only 18 percent of ACO high risk chronic illness patients participate in peer support groups or group visits, and only 24 percent of patients have access to both medical records and clinical notes in the record; 3) ACO leaders strongly believe patient activation and engagement is critical to ACO success and those who have such beliefs do have greater patient engagement at the actual point of care; 4) Engaging patients is very difficult challenging work as it often involves a total re-organization of workflow within physician practices including the re-allocation of tasks to other healthcare professionals, reorganization of time commitments, adjustment to use of electronic health records and training in communication methods.

Samuel Pannick, MA, MBBS, MRCP Imperial Patient Safety Translational Research Center, National Institute for Health Research and Imperial College London, London, England West Middlesex University Hospital National Health Service Trust, Middlesex, EnglandMedicalResearch.com Interview with: Samuel Pannick, MA, MBBS, MRCP Imperial Patient Safety Translational Research Center, National Institute for Health Research and Imperial College London West Middlesex University Hospital National Health Service Trust Middlesex, England Medical Research: What is the background for this study? What are the main findings? Response: Improving the quality of general medical ward care is a recognized healthcare priority internationally. Ward teams have been encouraged to structure their work more formally, with regular interdisciplinary team meetings and closer daily collaboration with their colleagues. Some early studies suggested that these changes might benefit patients, and help ward teams work more efficiently. However, team interventions on medical wards have been reported with numerous different outcome measures, and prior to this study, it was unclear what their objective benefits were. We showed that there is little agreement on the objective outcomes that best reflect the quality of interdisciplinary team care on general medical wards. Changes to interdisciplinary care aren’t reflected in the outcome measures that researchers choose most often, like early readmission rates or length of stay. Complications of care - although harder to record - might have more promise as a measure of the quality of inpatient team care in these specific medical areas. (more…)

MedicalResearch.com Interview with: Cécile Gaujoux-Viala, MD, PhD Université Montpellier I Chef de Service de Rhumatologie CHU de Nîmes Carémeau France Medical Research: What is the background for this study? Response: Chronic inflammatory rheumatic diseases – such as rheumatoid arthritis (RA), ankylosing spondylitis (AS), and psoriatic arthritis (PsA)  – confer significant patient and economic burdens : 1/5 of people with rheumatic conditions has been forced to change career, 1/3 will have stopped working within two years of onset and 1/2 will be unable to work within ten years. The addition of biological agents in treatment strategies for rheumatic diseases have improved the possibility of controlling disease activity and slowing the progression of joint damage. But these treatments are very expensive and their effect on work participation remains unclear. (more…)
