MedicalResearch.com Interview with: Dr-William-Patrick-Neil William P. Neil, MD Vascular Neurologist SCPMG Regional Stroke Champion Neurology    Medical Research: What is the background for this study? Dr. Neil: Stroke survivors are less likely to have a recurrent stroke, or other complications if they take their medications as prescribed by their doctor. Mail order pharmacies are increasingly being used to deliver medications for a variety of diseases, and their use is associated with better medication adherence.  We wanted to see whether stroke patients who use mail-order pharmacies were more likely to have good medication adherence than those who used  local pharmacies. Medical Research: What are the main findings? Dr. Neil: We looked through a large electronic medical database in California, and found a total of 48,746 people discharged from the hospital with a stroke, and who also filled either a cholesterol medication or an anticoagulant (blood thinner). Of these, 136,722 refills were from a local pharmacy and 68,363 were by mail. Overall, patients were adherent to the medications 46.5% of the time if they picked up the medication from the pharmacy and 74% of the time if they had prescriptions mailed to them. (more…)

MedicalResearch.com Interview with: Dr. Madhur Garg MD Professor, Clinical director, Department of Radiation Oncology Montefiore Einstein Center for Cancer Care Albert Einstein College of Medicine. Bronx, NY 10467 Medical Research: What is the background for this study? What are the main findings? Dr. Garg: In most curative settings, external beam radiotherapy (RT) for the treatment of solid tumors is delivered five days each week over multiple weeks in an outpatient setting. Unintended treatment prolongation, generally attributed to treatment toxicity or inter-current illness, has been associated with inferior tumor control in a number of disease sites. Montefiore Einstein Center for Cancer Care recently identified radiotherapy (RT) noncompliance as a prevalent issue among patients receiving RT with curative intent. Approximately 20% of patients were deemed to be noncompliant, and statistically significant predictors of noncompliance risk included diagnosis, treatment course length, and socioeconomic status (SES). In this report, we examined if radiotherapy noncompliance is associated with clinical outcomes in our patient population. In this analysis, we have found that treatment noncompliance is associated with inferior clinical outcomes for patients receiving radiotherapy with curative intent. The associations we detected were both statistically significant and clinically meaningful and consistent across disease sites. This is a novel finding that may have significant implications for how cancer care delivery can be improved, particularly in disadvantaged patient populations. Our finding that  radiotherapy noncompliance is strongly associated with inferior outcomes, even after adjusting for confounders such as comorbidity index and SES, suggests to us that noncompliance may serve as a behavioral biomarker for other risk factors that contribute to poor outcomes. These may include noncompliance with other important clinician visits and procedures, lack of social support, and mood disorders.

MedicalResearch.com Interview with: Shayna L. Henry, PhD Postdoctoral Research Fellow Department of Research & Evaluation Kaiser Permanente Southern California Medical Research: What is the background for this study? What are the main findings? Dr. Henry: In this study, we analyzed the electronic health records of 838,638 Kaiser Permanente members in Southern California. We decided to conduct this study because Kaiser Permanente always strives to advance standards of excellence for care, and even with all the outreach resources available to health care providers and staff, gaps in preventive care still arise. It can be hard to get patients engaged in managing their preventive care, because there are so many tasks for them to keep track of – many of which don’t happen on a very regular basis. Online patient portals have been very useful at helping patients get more engaged in their care, but patients still have to make the first move, and put all the pieces together. Our tool, the Online Personal Action Plan (oPAP), puts our members’ health status and preventive and chronic care tasks in a single dashboard, and alerts them via email to their upcoming care needs, prompting them to log in, view their upcoming health care tasks such as annual vaccinations, tests and blood draws for chronic conditions, and routine cancer screenings, and make the necessary medical appointments to close those gaps in care. We wanted to better understand if having access to the oPAP tools was associated with a higher likelihood of taking care of those outstanding health care tasks in a timely manner. We found that members who used oPAP were more likely to get a mammogram, Pap smear, receive colorectal cancer screenings, and more likely to complete HbA1c testing for diabetes within 90 days of their coming due compared to members who were not registered on our patient portal.   (more…)

MedicalResearch.com Interview with: Dr Marcel Yotebieng, PhD Department of Epidemiology Ohio State University, 304 Cunz Hall Columbus, OH Medical Research: What is the background for this study? What are the main findings? Response: With the current World Health Organization recommended treatment for the prevention of mother-to-child HIV transmission (PMTCT), the risk of transmission of HIV from an infected mother to her baby can be cut from 35-45% to less than 5% in breastfeeding population and <1% in non-breastfeeding population. But in sub-Saharan Africa where over 90% of HIV-infected pregnant women worldwide live, transportation costs and opportunity costs to attend regular clinic visits (to collect drugs) have been identified as important barriers to PMTCT. The provision of economic incentives has the potential to help women overcome these economic barriers. In addition, by creating immediate rewards that “nudge” individuals towards positive health behaviors, financial incentives can also address psychological barriers to health-seeking behavior of HIV-infected pregnant and breastfeeding women. This is the first study to use small cash incentives to encourage women to attend clinic visit and received available PMTCT care. We found that, among newly diagnosed HIV-infected women, small, incremental cash incentives resulted in increased retention along the  prevention of mother-to-child HIV transmission cascade and uptake of available services.

MedicalResearch.com Interview with: Dr. Clara Chow PhD Director of the Cardiovascular division The George Institute, Westmead Hospital Sydney, Australia Medical Research: What is the background for this study? What are the main findings? Dr. Chow: Text messaging has immense potential in healthcare. Not only for supporting medication adherence, but we have shown in the “TEXT ME” study its ability to simultaneously influence multiple lifestyle domains like increasing physical activity, embarking on healthier diets and reducing smoking rates. With increasing penetration of mobile phone use in developed as well as developing countries, there is a potential for wider reach, however there remains a need to evaluate the value of text messaging programs in various patient populations to establish the generalizability of these research findings.

MedicalResearch.com Interview with: Dr. Tracy Wang MD MHS MSc Assistant Dean, Continuing Medical Education Director, Center for Educational Excellence Fellowship Associate Program Director Associate Professor of Medicine, Cardiology Duke Clinical Research Institute Medical Research: What is the background for this study? What are the main findings? Response: Medication non-adherence is a known challenge in the management of patients with coronary artery disease. Barriers to adherence are multifactorial, attributed to patient, healthcare provider, and social determinants. However, whether patient medication adherence varies across different hospitals is unknown. In this study, we sought to determine whether inter-hospital differences exist in the degree of patient adherence to secondary prevention medications after discharge. Moreover, we assessed whether these hospital-specific variations in medication adherence, if any, correspond to downstream patient outcomes. We observed that the majority of post-MI patients were prescribed guideline-recommended secondary prevention medications at discharge. However, among those prescribed, we see a significant decline in the use of these medications within just 90 days after discharge. Medication adherence rates varied markedly across U.S. hospitals, with the widest variation seen for post-discharge use of beta-blockers. Hospitals with high post-discharge  medication adherence were associated with significantly lower risk of major adverse cardiovascular events and death or all-cause readmissions when compared with hospitals with low adherence rates, even after adjustment for differences in patient case-mix.

Author Interviews, Columbia, Compliance, HIV, JAMA, Pediatrics / 04.11.2015

MedicalResearch.com Interview with: Dr. Louise Kuhn PhD Professor, Epidemiology Sergievsky Center Columbia University  Medical Research: What is the background for this study? What are the main findings? Dr. Kuhn: Ritonavir-boosted lopinavir-based antiretroviral therapy is recommended as first-line treatment for HIV-infected infants and young children while efavirenz is recommended for adults and older children. There are several advantages of transitioning HIV-infected children to efavirenz-based treatment as they get older.  These advantages include the possibility of once-daily dosing, simplification of co-treatment for tuberculosis, avoidance of some metabolic toxicities, preservation of ritonavir-boosted lopinavir for second-line treatment, and alignment of adult and pediatric treatment regimens. However, there have been concerns about possible reduced viral efficacy of efavirenz-based treatment in children exposed to nevirapine for prevention of mother-to-child transmission.  This is because efavirenz and nevirapine are in the same drug class and the majority of children who become infected despite exposure to nevirapine used for prevention have mutations in their virus that usually predict resistance to this drug class. In this study, we randomized HIV-infected children to two different treatment strategies: In the control strategy they remained on their initial ritonavir-boosted lopinavir regimen; in the alternative strategy they transitioned to an efavirenz-based regimen.  All children had been exposed to nevirapine used (unsuccessfully) to prevent mother to child HIV transmission and were virologically-suppressed (HIV in blood < 50 copies/ml) at the time of enrollment into the study.  We observed excellent virological control in both groups with fewer than 3% of children having levels of HIV in their blood greater than 1000 copies/ml.  Sustained suppression of virus in blood below 50 copies/ml throughout follow-up was achieved in 82% of the children transitioned to efavirenz-based treatment compared to 72% of children remaining on the control treatment.

Dr M Lobo PhD FRCP Director Barts BP Centre of Excellence Consultant Physician and Hon Senior Lecturer NIHR Barts Cardiovascular Biomedical Research Unit William Harvey Research Institute, London MedicalResearch.com Interview with: Dr M Lobo PhD FRCP Director Barts BP Centre of Excellence Consultant Physician and Hon Senior Lecturer NIHR Barts Cardiovascular Biomedical Research Unit William Harvey Research Institute, London Medical Research: What hypothesis did you set out to investigate and why? Dr. Lobo: We investigated the clinical utility of a novel treatment algorithm for multi-drug intolerant patients with hypertension who are at very high risk of cardiovascular disease due to uncontrolled blood pressure and inability to take conventional (guideline-based) antihypertensive regiments. These patients are often poorly managed by primary care physicians (or specialists such as cardiologists) because there has been little interest/research in medication intolerance. There has however been a major focus on drug non-adherence as a cause of failure to control hypertension - we believe that a key cause of non-adherence is medication intolerance which patients do not always volunteer. Medical Research: What is the report's ultimate take-away message? Dr. Lobo: Our novel stepwise algorithm was successful in managing uncontrolled hypertension in the majority of patients without needing an increase in their medicines burden. The message therefore is that patients who do not tolerate their antihypertensives do not have to put up with side effects and resultant poor quality of life as we have demonstrated that there are ways to get around medication intolerances.

Louanne Bakk, Ph.D. Assistant Professor Director, Institute on Innovative Aging Policy and Practice School of Social Work The University at Buffalo Buffalo, NY 14260 MedicalResearch.com Interview with: Louanne Bakk, Ph.D Assistant Professor Director, Institute on Innovative Aging Policy and Practice School of Social Work The University at Buffalo Buffalo, NY  14260 Medical Research: What is the background for this study? What are the main findings? Dr. Bakk: Medicare Part D reduces out-of-pocket health care costs and increases access to medications.  While overall the benefit has facilitated the purchase of medications, cost sharing exists and be particularly difficult for more vulnerable populations.  Racial and gender disparities in cost-related nonadherence (CRN)  exist under Medicare Part D plans.  However, it was unknown whether the impact of the coverage gap on older Blacks and females.  This study examined whether the Medicare Part D coverage gap directly and indirectly affects the relationship between race, gender, and CRN. Racial differences in cost-related nonadherence were largely driven by reaching the coverage gap.  In other words, the gap appears to be more difficult for older Blacks than Whites.  Additionally, both reaching and not reaching the coverage gap, poorer health and having a lower income were associated with cost-related nonadherence .

What are the main findings? Dr. Pourat: We have succeeded to insure most of the uninsured population in the U.S., but now have to figure out how to reduce costs while improving health. We had the opportunity to examine the role of continuity with a primary care provider, which is one of the pathways that looked promising in improving health and reducing costs. We were evaluating a major demonstration program in California called the Health Care Coverage Initiative (HCCI) and one of the participating counties implemented a policy to increase adherence by only paying for visits if patients went to their assigned providers. We examined what happened to patients who always or sometimes adhered to their provider versus those who never adhered. We found that adherence or continuity reduced emergency department use and hospitalizations. This would lead to savings because of the high costs of these services. Medical Research: What should clinicians and patients take away from your report? Dr. Pourat: The study shows that both patients and clinicians would benefit from continuity with the primary care provider. Clinicians can actually make a difference in helping patients: they can teach patients about self-care and help them manage their conditions better. Patients would benefit from following through with treatment plans and experience less medical error and duplication of services which are potentially harmful. Continuity fosters rapport and trust between patients and providers and can be beneficial to both. (more…)

Robin Mathews, MD Duke Clinical Research Institute Duke University Medical Center Durham, NCMedicalResearch.com Interview with: Robin Mathews, MD Duke Clinical Research Institute Duke University Medical Center Durham, NC Medical Research: What is the background for this study? What are the main findings? Dr. Mathews: Though treatment for patients with an acute myocardial infarction with evidence based therapies has increased significantly over the years, adherence to these therapies after discharge remain sub optimal. We used a validated instrument, the Morisky scale, to assess patient medication adherence.  We found that in a contemporary population of 7,425 patients across 216 hospitals, about 30% of patients were not adherent to prescribed cardiovascular medications as early as 6 weeks after discharge. Patients with low adherence were more likely to report financial hardship as well as have signs of depression. In addition, we found that patients who had follow up arranged prior to discharge and those that received explanations from the provider on the specific medications, were more often adherent to therapies. There was a non significant increase in risk of death or readmission at 2 months (HR [95% CI]: 1.35 [0.98-1.87]) among low adherence patients. (more…)

Andre Paixao, MD Division of Cardiology Emory University Atlanta, GA, 30322.MedicalResearch.com Interview with: Andre Paixao, MD Division of Cardiology Emory University Atlanta, GA, 30322. Medical Research: What is the background for this study? Dr. Paixao: Despite advances in cardiovascular prevention, coronary heart disease remains a major cause of morbidity and mortality. Understanding risk factor burden and control as well as perceived risk prior to acute myocardial infarction (MI) presentation may identify opportunities for system-based interventions to promote adherence to evidence based recommendations and improve overall cardiovascular health. Medical Research: What are the main findings? Dr. Paixao: Our study assessed predicted risk and risk factor control prior to Myocardial Infarction (MI) presentation in 443,117 patients included in the NCDR ACTION Registry-GWTG. Only 36.1% of patients met all assessed risk factor control metrics (i.e. LDL cholesterol, non-HDL cholesterol, nonsmoking status and aspirin use among those with prior cardiovascular disease). Risk factor control was suboptimal in the primary and secondary prevention groups. Prior cardiovascular disease was present in 41.6% of patients presenting with an acute MI. Among those without prior cardiovascular disease or diabetes, only 13.4% were classified as high risk based on the Framingham Risk Score. (more…)

MedicalResearch.com Interview with: Amneet Sandhu, MD Department of Internal Medicine Division of Cardiovascular Medicine University of Colorado Aurora, CO 80045. Medical Research: What is the background for this study? What are the main findings? Dr. Sandhu: Control of hypertension has improved nationally to guideline recommended levels.  To date, the focus of hypertensive care has been around identification and appropriate treatment to blood pressure goals.  Less emphasis has been placed on maintenance of control or tracking patients with high rates of relapse after achieving control. This study sought to assess the rate of recidivism in a cohort of hypertensive patients with controlled blood pressure and identify patient and process of care factors associated with recidivism.  We found approximately 25% of hypertensive patients with baseline controlled blood pressure relapse over a median time period of 7.3 months.  Patients with diabetes, high normal baseline blood pressure and poor medication adherence were more likely to suffer from recidivism.

Marya Viorst Gwadz, Ph.D Senior Research Scientist Director, Transdisciplinary Methods Core Center for Drug Use and HIV Research (CDUHR) New York University College of Nursing New York, NY 10010 MedicalResearch.com Interview with: Marya Viorst Gwadz, Ph.D Senior Research Scientist Director, Transdisciplinary Methods Core Center for Drug Use and HIV Research (CDUHR) New York University College of Nursing New York, NY 10010 Medical Research: What is the background for this study? Dr. Gwadz: HIV is a major success story in that the tolerability, convenience, and efficacy of antiretroviral medications have improved dramatically over the last decade. A number of years ago in the course of another research study with vulnerable individuals infected with HIV in New York City, and we noticed that a substantial proportion of study participants were medically eligible for HIV medications, and had access to medications, but had declined or stopped taking them. We then turned our attention to understanding why this is the case, that is, to identify the individual, social, and structural barriers that persons living with HIV/AIDS (PLHA) experience to antiretroviral therapy. We focused in particular on African American/Black and Latino/Hispanic PLHA, because the overall emphasis of our research group at the NYU College of Nursing is the development and evaluation of culturally targeted intervention approaches to address health disparities. Around 2011, studies of the “HIV cascade of care” began to emerge, which highlighted the problem of poor engagement in HIV care and antiretroviral therapy nationally. The ultimate goal of HIV treatment is viral suppression, but at present, the Centers for Disease Control and Prevention (CDC) estimates that we have achieved that goal with only 30% of PLHA. Medical Research: What kind of intervention approach that emerged from these background findings? Dr. Gwadz: We found that barriers to HIV medication are complex and multi-faceted for PLHA from African American/Black and Latino/Hispanic backgrounds. In particular, PLHA experience serious emotional barriers to the uptake of HIV medications, such as fear of side effects, stigma, and disclosure of HIV status. Further, high rates of substance use and mental health distress, and barriers to accessing services for these concerns, impede medication uptake. Moreover, PLHA who are wary of HIV medication tend to avoid HIV primary care, often because they do not want to feel pressured to take medications, or explain to their providers why they are not taking them. So poor engagement in HIV care, which is very common among PLHA, and low uptake of HIV medication are actually related problems. With funding from the National Institute of Mental Health (grant #R34MH093352), and in collaboration with Mount Sinai Beth Israel and Mount Sinai St. Luke’s-Roosevelt Hospital Center, we developed a multi-component culturally targeted intervention grounded in the Motivational Interviewing approach that included three individual sessions, 12-24 weeks of patient navigation (as needed), up to five support groups with other PLHA who had declined medication, which were co-led by a “successful” peer who was engaged in HIV care and were taking HIV medication with good adherence. One novel aspect of the intervention was its focus on emotional barriers to HIV medication, and the program’s “no pressure, no judgment” stance, congruent with the Motivational Interviewing approach, was key to engaging participants into the study to talk about these difficult issues.

Prof.- Medicine and Cardiology Clinical Trials & Global Health Studies Icahn School of Medicine at Mount SinaiMedicalResearch.com Interview with: Sameer Bansilal, MD, MS Asst. Prof.- Medicine and Cardiology Clinical Trials & Global Health Studies Icahn School of Medicine at Mount Sinai Medical Research: What is the background for this study? What are the main findings? Dr. Bansilal: Our group has previously published data from FREEDOM, COURAGE and BARI showing that adherence to recommended therapies are low in diabetic (DM) patients. We have spent the last decade developing a potential solution to this- the Fuster-Ferrer polypill. This study was done to better inform the association between levels of medication adherence and long term major adverse cardiovascular events (MACE) in high risk diabetic patients. We analyzed a U.S. health insurers’ claims data for 19,962 high risk diabetic subjects. Using proportion of days covered (PDC) for 1 year after first refill, we stratified patients as fully adherent (FA≥80%), partially adherent (PA ≥40- ≤79%) or non-adherent (NA <40%) and examined the associations with a primary cardiovascualr outcome measure of death, myocardial infarction, stroke and coronary revascularization. We found that only 34% participants were fully adherent to therapy. When compared to being non-adherent at 2 yrs follow up,, being fully adherent was associated with a 28% lower rate of MACE; being partially adherent was associated with a 21% lower rate of MACE. Efforts towards improving adherence in diabetic subjects may lead to substantial reductions in MACE. (more…)

MedicalResearch.com Interview with: Avinash Pandey, the study author, is a high school student who conducted this study under the guidance of his mentor, Niteesh K. Choudhry., M.D., Ph.D., executive director of the Center for Healthcare Delivery Sciences, Brigham and Women’s Hospital, Harvard Medical School, Boston, Mass. Medical Research: What is the background for this study? What are the main findings? Response: Numerous studies have demonstrated that there is poor adherence to medications in cardiac patients (coronary artery disease patients, CAD). Despite the fact that non-adherence to these medications can have serious consequences on long-term health like disease progression, increased risk of cardiac events and premature mortality, many patients consistently miss their medications and many stop their medications only months after they are prescribed. This non-compliance leads to high costs for the health care system and more potentially preventable cardiac events. Studies suggest, that for the vast majority of patients, non-adherence to medications is not intentional. A significant portion simply forget to take their medications. Although many systems are available today to reduce medication non-adherence, like pill boxes and blisterpacks, these have demonstrated limited effect on medication adherence. Other systems may be expensive to purchase and cumbersome to use or of limited availability. With the proliferation of cellphones, text message reminders could represent a simple, cost-effective method to improve adherence to medications. This research began as a high school science fair project 4 years ago and has evolved into a large ongoing assessment of the impact of mobile technologies on adherence to evidence based therapies and lifestyle interventions in a broad cross-section of cardiovascular patients and those at risk for cardiovascular disease. The current report examines the impact of an automated computer program which sends free, personalized text messages to remind patients to adhere to their medications. 30 CAD patients were recruited from a single centre cardiac practice, in this 2 month cross-over study. Patients were randomized to either receive text message reminders in the first month or the second month. Adherence of each patient was compared between months. Text message reminders were shown to significantly impact medication adherence. Patients missed on average 60% less doses when receiving text message reminders. These numbers were even greater when looking at pre-specified groups identified in previous studies to be at high risk of medication non-adherence, including depression patients, dementia patients, elderly patients, and patients with less than 12 years of education. All patients improved with text message reminders but those with the lowest adherence improved the most. Although this study did not examine clinical outcomes, the text message reminder system appears to be a simple and widely applicable method to improve adherence to medications. The system is free to operate and represents no cost for patients receiving messages. Thus it could be implemented at an individual level or by physicians and clinics to improve patient adherence to medications. (more…)

Response: Non-adherence is a serious issue in type 1 diabetes management. It leads to poor glycemic control and peaks in adolescence and young adulthood. Peer support is critical for young patients yet few studies examined whether pairing youth with slightly older and more experienced peers with diabetes improves their diabetes self-management and glycemic control. This study had two aims: (1) assess whether adolescents (as prospective mentees) and young adults (as prospective mentors) with diabetes would be interested in peer mentoring as a way to improve adherence, and (2) identify contents and delivery modes for a peer mentoring topic from the perspective of patients and their parents. Fifty-four adolescents and 46 young adults with type 1 diabetes were surveyed. (more…)

Robert Hutchins, M.D., M.P.H. Department of Medicine, Division of General Internal Medicine UCSFMedicalResearch.com Interview with: Robert Hutchins, M.D., M.P.H. Department of Medicine, Division of General Internal Medicine UCSF Medical Research: What is the background for this study? What are the main findings? Dr. Hutchins: "Utility" refers to the effect on quality of life that a certain intervention carries and a utility value generally varies from 0-1.0.  The more negative the effect is, the lower the utility value (closer to 0), and the less it affects quality of life, the closer to 1.0 it is.  On a theoretical scale, "perfect health" is 1.0 and death is 0.  There are a number of studies that -- USE a utility value for taking pills, generally between 0.95 and 1.0.  However, many cost-effectiveness analyses ignore the utility value altogether, or arbitrarily choose 1.0 as the utility.  We found that a small change in the utility value can have a very large effect on the overall cost-effectiveness of an intervention.  We found that the utility value of taking pills, assessed by three different commonly used methods, to be 0.990-0.994, depending on the method.

Richard J. Holden, PhD Assistant Professor Department of BioHealth Informatics Indiana University School of Informatics and Computing – Indianapolis Indianapolis, IN 46202MedicalResearch.com Interview with: Richard J. Holden, PhD Assistant Professor Department of BioHealth Informatics Indiana University School of Informatics and Computing – Indianapolis Indianapolis, IN  46202 Medical Research: What was your motivation for this study? Dr. Holden: Many patients arrive in the emergency room with acute heart failure (AHF), a worsening of their chronic heart failure condition. These visits and subsequent hospital admissions and readmissions for acute heart failure represent a sizeable cost in the US healthcare system. Evidence suggests that some of these cases could be prevented if patients were better able to perform self-care activities such as monitoring their symptoms, taking medications, getting exercise, and maintaining a sodium-restricted diet. However, in community-based studies that we and others have done, patients with heart failure face a variety of barriers to optimally performing self-care. We therefore created an instrument to assess barriers to self-care, which we designed to be implemented in the emergency room. We tested the instrument with 31 patients with acute heart failure at Vanderbilt University’s adult Emergency Department. Medical Research: What are the main findings? Dr. Holden: Almost everyone who participated reported experiencing barriers to self-care. A median of 15 barriers per patient were reported. Of the 47 barriers that we tested, 34 were reported by at least one quarter of participants. The top ten most prevalent barriers included individual-level factors such as physical disability, disease knowledge, and memory deficits as well as factors related to the organization of home life, including major disruptions such as holidays. Other barriers were related to inadequate health information, low literacy, and lack of resources. Many barriers interacted with one another, for example, lack of transportation yet not wanting to rely on others. We found that the instrument could be feasibly administered within a short period following the patient’s emergency room arrival. (more…)

What are the main findings? Response: Asthma is one of the most common childhood conditions, affecting 1 in 4 children in New Zealand.  Although there are many effective medications available for asthma, of which the most important are inhaled corticosteroids, asthma control remains suboptimal due to poor adherence.  In children, adherence to regular preventive asthma therapy is about 50%, and can be as low as 30%.  Our randomised controlled trial looked at use of an electronic monitoring device with an in-built audiovisual reminder to see if it improved adherence and asthma control.  We recruited 220 children aged between 6-15yrs, who presented to the emergency department with asthma and randomised them to receive the device either with the audiovisual function enabled or disabled.  It found that those who received the audiovisual reminder (the intervention arm) took a median of 84% of their inhaled corticosteroids compared to just 30% in those who did not receive the reminder (control arm).  This equates to a 180% improvement in adherence.  We found significant improvements also in asthma control (including reduced asthma symptoms and increased participation in daily activities) and a reduction in reliever use from 17.4% to 9.5% in those who received the reminder.

What are the main findings? Response:  Influenza can be a very serious disease and is more than just a bad cold.  Some children who are 6 months through 8 years need two doses of the influenza vaccine in a season depending on if and when they received previous influenza vaccine doses. We know that only about half of these families who want to vaccinate their children against the flu and get the first dose, come back to get the second dose. (more…)

Mendu, M.D. Division of Renal Medicine Brigham and Women’s Hospital Boston, MA 02115. Medical Research: What are the main findings of the study? Dr. Mendu: Our study found that implementation of a chronic kidney disease (CKD) checklist, a tool that succinctly and clearly outlines CKD management guidelines, in a primary care clinic improved adherence to a number of significant management guidelines. We conducted a prospective study during a one year period among 13 primary care providers, four of whom were assigned to use a CKD checklist incorporated into the electronic medical record during visits with patients with CKD. Patients whose providers utilized a CKD checklist had higher rates of adherence to annual albuminuria testing, parathyroid hormone testing, phosphate testing, achieving a hemoglobin A1c target<7, documentation of avoidance of nonsteroidal anti-inflammatory drugs, use of an angiotensin-converting enzyme inhibitor or angiotensin-receptor blocker and vaccination for annual influenza and 5-year pneumococcus.

Dr. Heli Halava: Departments of Public Health and Pharmacology, Turku, FinlandMedicalResearch.com Interview with: Dr. Heli Halava: Departments of Public Health and Pharmacology, Turku, Finland MedicalResearch: What are the main findings of the study? Dr. Halava: The associations between lifestyle factors and nonadherence to statin therapy varied by cardiovascular comorbidity status. Of the participants without cardiovascular comorbidities (n = 6458), 3171 (49.1%) were nonadherent with their statin therapy. Of the participants with cardiovascular comorbidities (n = 2827), 1155 (40.9%) were nonadherent. People with cardiovascular comorbidities who had risky drinking behaviours or a cluster of lifestyle risks were at increased risk of nonadherence. (more…)

Dr. Stroup: We conducted a study sponsored by the National Institute of Mental Health that compared long-acting injectable antipsychotics for people with schizophrenia. Long-acting injectable antipsychotics, also known as depot antipsychotics, are used to promote treatment adherence.  We compared a newer injectable antipsychotic, paliperidone palmitate, to an older one, haloperidol decanoate.  We did not find an advantage for the newer drug in overall effectiveness.  The drugs performed very similarly, and were tolerated about the same.

Dawn L. Hershman, MD MS Associate Professor of Medicine and MedicalResearch.com Interview with: Dawn L. Hershman, MD MS Associate Professor of Medicine and Epidemiology Leader, Breast Cancer Program Herbert Irving Comprehensive Cancer Center Columbia University Medical Center MedicalResearch.com: What are the main findings of the study? Dr. Hershman: We have found in the past that compliance to 5 years of hormone therapy for the adjuvant treatment of breast cancer is low. While toxicity is a main reason, other factors are also important. Recent studies suggest out of pocket costs are high among cancer patients. We evaluated the change in adherence to hormone therapy after the introduction of generic Aromatase inhibitors. We found that discontinuation decreased and adherence increased with generic aromatase inhibitors compared to brand name. we found that higher co-payments were associated with decreased adherence and increased discontinuation. We also found that patients in the highest income group were more likely to be adherent to hormone therapy. (more…)
