Article Synopsis
  • A study investigated patient safety in outpatient care across 11 sites in Massachusetts, focusing on the incidence of adverse events (AEs) among 3,103 patients in 2018.
  • Results showed that 7% of patients experienced at least one AE, with adverse drug events being the most frequent, while 23% of these AEs were deemed preventable.
  • The study found variations in AE rates based on factors like age and race, highlighting the need for improved patient safety measures in outpatient settings.

Background: Inadequate communication during transitions of care is a major health care quality and safety vulnerability. In 2013 Massachusetts General Hospital (MGH) embarked on a comprehensive training program using a standardized handover system (I-PASS) that had been shown to reduce adverse events by 30% even when not completely executed on each patient. In this cross-sectional study, the authors sought to characterize handover practices six years later.

Background: Adverse events during hospitalization are a major cause of patient harm, as documented in the 1991 Harvard Medical Practice Study. Patient safety has changed substantially in the decades since that study was conducted, and a more current assessment of harm during hospitalization is warranted.

Methods: We conducted a retrospective cohort study to assess the frequency, preventability, and severity of patient harm in a random sample of admissions from 11 Massachusetts hospitals during the 2018 calendar year.

Article Synopsis
  • The study aimed to update the types of health care harm measures by gathering expert opinions on contemporary adverse event indicators through a modified World Café method.
  • Experts rated a total of 525 triggers and measures, with a significant portion deemed to have high clinical importance and suitability for evaluation via chart review or electronic monitoring.
  • The findings highlight the effective use of the World Café method in prioritizing critical healthcare measures, with plans for further validation of these measures to reduce reliance on manual chart reviews.

Patient tracers and leadership WalkRounds proactively identify quality and safety issues. However, these programs have been inconsistent in application, results, and sustainability. The goal was to identify a more consistent and efficient approach to survey health care facilities.

Safety assessment codes (SACs) are one method to evaluate adverse events and determine the need for a root cause analysis. Few facilities currently use SACs, and there is no literature examining their interrater reliability. Two independent raters assigned frequency, actual harm, and potential harm ratings to a sample of patient safety reports.

De novo thrombotic microangiopathy (TMA) following renal transplantation is a severe complication associated with high rates of allograft failure. Several immunosuppressive agents are associated with TMA. Conventional approaches to managing this entity, such as withdrawal of the offending agent and/or plasmapheresis, often offer limited help, with high rates of treatment failure and graft loss.

Functional neuroimaging was employed to study 10 obese and 10 lean healthy young right-handed women, divided equally into binge and non-binge eaters. Subjects were presented with visual and auditory stimuli of binge type foods, non-binge type foods, and non-food stimuli in the fMRI scanner. Brain areas activated by both the visual and auditory stimuli across all individual subjects within a particular group was observed only for the binge food stimuli in the obese binge eaters, in the right premotor area, involved in planning of motor behavior.
