MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Venous thromboembolism, including deep vein thrombosis and pulmonary embolism, is a complication of critical illness. Studies have demonstrated that despite pharmacologic thromboprophylaxis with unfractionated heparin or low-molecular weight heparin, 5-20% of critically ill patients develop deep vein thrombosis (DVT). The PREVENT trial evaluated whether adjunctive intermittent pneumatic compression reduces incident proximal lower limb DVT as detected on twice-weekly lower limb ultrasonography in critically ill patients receiving pharmacologic thromboprophylaxis with unfractionated heparin or low-molecular-weight heparin.

The trial was conducted in 20 sites in Saudi Arabia, Canada, Australia and India and included 2003 patients.

The trial found no difference in the primary end point of proximal leg DVT. The addition of intermittent pneumatic compression to pharmacologic thromboprophylaxis did not result in a lower incidence of pulmonary embolism or a composite outcome of venous thromboembolism or death from any cause at 28 days when compared to pharmacologic thromboprophylaxis alone.

MedicalResearch.com: What is the background for this study?

Response: The American College of Surgeons Commission on Cancer is implementing a National Accreditation Program for Rectal Cancer (NAPRC), aiming to improve and standardize the quality of rectal cancer care in the United States. While this is a commendable goal, previous accreditation programs in other specialties have faced controversy around their uncertain impact on access to care. Furthermore, it is well established that the quality of rectal cancer care is associated with patients’ socioeconomic position. So, the NAPRC could have the unintended consequence of widening disparities and limiting access to high quality rectal cancer care for certain patient populations.  Continue reading

MedicalResearch.com: What is the background for this study? What are the main findings? 

Response: Patients who suffer in-hospital cardiac arrest at nights and during weekends (off-hours) are known to have lower rates of survival to hospital discharge, compared to their counterparts who have cardiac arrest during the daytime on weekdays (on-hours). Since overall survival to hospital discharge has improved over the past decade for the approximately 200,000 patients who experience in-hospital cardiac arrest annually, our study sought to determine whether survival differences between off-hours and on-hours arrest has changed over time.

On-hours was categorized as 7:00 a.m. to 10:59 p.m. Monday to Friday. Off-hours was categorized as 11:00 p.m. to 6:59 a.m. Monday to Friday or anytime on weekends. Among 151,071 adult patients in the GWTG-Resuscitation registry who experienced in-hospital cardiac arrest between January 2000 and December 2014, slightly over half (52%) suffered a cardiac arrest during off-hours. We found that survival to hospital discharge improved significantly in both groups over the study period — for on-hours: from 16.0% in 2000 to 25.2% in 2014; for off-hours: 11.9% in 2000 to 21.9% in 2014.

However, despite overall improvement in both groups, survival from in-hospital cardiac arrest at nights during off-hours remained significantly lower compared to on-hours by an absolute 3.8%.

MedicalResearch.com: What should readers take away from your report? 

Response: Survival to hospital discharge has improved in both groups of patients. This is reassuring and suggests that health care providers and hospital systems must be doing something right. However, the persistent survival disparities between on-hours and off-hours arrests remains concerning. To ensure that improved survival trends are sustained over time, narrowing this gap must be made an area of focus for quality improvement efforts. Data regarding mediator variables, such as physician and nurse staffing patterns and how they changed over the course of the study was not available for this study. 

MedicalResearch.com: What recommendations do you have for future research as a result of this work? 

Response: Since timing of in-hospital cardiac arrest appears to impact survival outcomes, future research should aim at identifying factors that may be associated with these described survival discrepancies and care processes that mitigate against them.

Medical Research: What is the background for this study?

Response: We wanted to test whether hospitals with better nursing work environments displayed better outcomes and value than those with worse nursing environments, and to determine whether these results depended on how sick patients were when first admitted to the hospital.

Medical Research: What are the main findings?

Response: Hospitals with better nursing work environments (defined by Magnet status), and staffing that was above average (a nurse-to-bed ratio greater than or equal to 1), had lower mortality than those hospitals with worse nursing environments and below average staffing levels. The mortality rate in Medicare patients undergoing general surgery was 4.8% in the hospitals with the better nursing environments versus 5.8% in those hospitals with worse nursing environments. Furthermore, cost per patient was similar. We found that better nursing environments were also associated with lower need to use the Intensive Care Unit. The greatest mortality benefit occurred in patients in the highest risk groups.
