Observational Study
Social Determinants of Health and Risk-Adjusted Sepsis Mortality in the Nationwide Veterans Affairs Healthcare System.
Traditional risk prediction and risk adjustment models have focused on clinical characteristics, but accounting for social determinants of health (SDOH) and complex health conditions could improve understanding of sepsis outcomes and our ability to predict outcomes, treat patients, and assess quality of care. ⋯ In patients with community-acquired sepsis, adjusting for community SDOH variables such as ADI did not improve 90-day sepsis mortality predictions in mortality models and did not substantively alter hospital performance within the VA Healthcare System. Understanding the role of SDOH in risk prediction and risk adjustment models is vital because it could prevent hospitals from being negatively evaluated for treating less advantaged patients. However, we found that in VA hospitals, the potential impact of SDOH on 90-day sepsis mortality was minimal.

Observational studies have reported an association between metformin and improved outcomes in COVID-19, but most have been small and with significant limitations. ⋯ Pre-admission metformin use was associated with lower risk of in-hospital mortality and markers of disease severity among adults with diabetes mellitus without CKD and not requiring hemodialysis who were hospitalized with COVID-19 infection.

Patterns of Care Following a Positive Fecal Blood Test for Colorectal Cancer: A Mixed Methods Study.
Multilevel barriers to colonoscopy after a positive fecal blood test for colorectal cancer (CRC) are well-documented. A less-explored barrier to appropriate follow-up is repeat fecal testing after a positive test. We investigated this phenomenon using mixed methods. ⋯ Among patients in this cohort, 7.4% repeated fecal testing after an initial positive test. Of those, over half did not go on to receive a colonoscopy within 1 year. Efforts to improve CRC screening must address repeat fecal testing after a positive test as a barrier to completing colonoscopy.

Guidelines for managing abnormal cervical cancer screening results are complex and adherence is challenging for clinicians. Previous studies have identified gaps in knowledge as a possible cause; few have explored the confidence clinicians have in their management decisions. Confidence in decision-making may influence management practices, particularly when guidelines are complex and evolving. ⋯ Clinician confidence in management decisions for abnormal cervical cancer screening results was significantly associated with knowing guideline-concordant recommendations. Given the complexity of cervical cancer management guidelines, solutions to improve clinician confidence in decision-making are needed.

Contribution of Potentially Inappropriate Medications to Polypharmacy-Associated Risk of Mortality in Middle-Aged Patients: A National Cohort Study.
The role of potentially inappropriate medications (PIMs) in mortality has been studied among those 65 years or older. While middle-aged individuals are believed to be less susceptible to the harms of polypharmacy, PIMs have not been as carefully studied in this group. ⋯ PIMs were independently associated with increased mortality, and partially explained polypharmacy-associated mortality in middle-aged people. Other mechanisms of injury from polypharmacy should also be studied.
