Biopsychosocial factors associated with complications in patients with frostbite.

Cold weather injuries can be devastating and life changing. Biopsychosocial factors such as homelessness and mental illness (especially substance use disorders [SUDs]) are known risk factors for incurring frostbite. Based on clinical experience in an urban level 1 trauma center, we hypothesized that complications following frostbite injury would be influenced by homelessness, SUDs, and other forms of mental illness. The aim of this study was to examine the relationship between biopsychosocial factors and both amputations and unplanned hospital readmissions after cold injuries. Patients admitted with a diagnosis of frostbite between the winters of 2009 and 2018 were included in this retrospective cohort study. Descriptive statistics and multivariable regression assessed factors associated with outcomes of interest. Of the 148 patients in the study, 40 had unplanned readmissions within 1 year. Readmitted patients were significantly less likely to have a stable living situation (48.7% vs 75.0%, P = .005) and more likely to have an SUD (85.0% vs 60.2%, P = .005) or other psychiatric disorder (70.0% vs 50.9%, P = .042). Homelessness and SUDs were independent predictors of unplanned readmission. Overall, 18% of frostbite injuries resulted in amputation. Any history of drug and/or alcohol use independently predicted amputations. The study results suggest that additional hospital and community resources may need to be marshaled to prevent vulnerable patients with biopsychosocial risk factors from having complications after frostbite. Complications place a high downstream burden on healthcare systems. Clinicians caring for frostbite patients with comorbid conditions can use these findings to inform care and discharge decisions.

The use of mystery shopping for quality assurance evaluations of HIV/STI testing sites offering services to young gay and bisexual men.

Young men who have sex with men (YMSM) are at increased risk for HIV and STI infection. While encouraging HIV and STI testing among YMSM remains a public health priority, we know little about the cultural competency of providers offering HIV/STI tests to YMSM in public clinics. As part of a larger intervention study, we employed a mystery shopper methodology to evaluate the LGBT cultural competency and quality of services offered in HIV and STI testing sites in Southeast Michigan (n = 43).We trained and deployed mystery shoppers (n = 5) to evaluate the HIV and STI testing sites by undergoing routine HIV/STI testing. Two shoppers visited each site, recording their experiences using a checklist that assessed 13 domains, including the clinic's structural characteristics and interactions with testing providers. We used the site scores to examine the checklist's psychometric properties and tested whether site evaluations differed between sites only offering HIV testing (n = 14) versus those offering comprehensive HIV/STI testing (n = 29). On average, site scores were positive across domains. In bivariate comparisons by type of testing site, HIV testing sites were more likely than comprehensive HIV/STI testing clinics to ascertain experiences of intimate partner violence, offer action steps to achieve safer sex goals, and provide safer sex education. The developed checklist may be used as a quality assurance indicator to measure HIV/STI testing sites' performance when working with YMSM. Our findings also underscore the need to bolster providers' provision of safer sex education and behavioral counseling within comprehensive HIV/STI testing sites.
