Characteristics and outcomes of prisoners hospitalized due to COVID-19 disease.

ABSTRACT

BACKGROUND: Correctional facilities have faced unique challenges during the COVID-19 pandemic. A COVID-19 outbreak was reported in the Federal Medical Center (FMC) in Lexington, Kentucky, a prison for inmates requiring medical and mental care. The main objective of this study was to examine clinical characteristics and outcomes of prisoners vs. non-prisoners admitted to the hospital due to COVID-19 disease. MATERIALS AND METHODS: We did a retrospective, comparative cohort study of 86 consecutive COVID-19 patients admitted to the University of Kentucky hospital between March 1 and June 1, 2020. Among these, 37 patients were inmates from a single local FMC and 49 were non-inmates. RESULTS: Mean (SD) age of the cohort was 59.1 (14.5) years, 68.6% were male and 61.6% white. All inmates were men. No significant differences in age or race were observed between inmates and non-inmates. Hypertension (81%), obesity (62%), COPD/asthma (43%), diabetes (41%), coronary artery diseases (38%), and chronic kidney disease (22%) were among the most common comorbidities prevalent in inmates. Inmates had overall higher serum creatinine and C-reactive protein, more proteinuria, and lower platelet counts at the time of hospital admission when compared to non-inmates. Incidence of acute kidney injury (AKI) was more frequent in inmates (68 vs. 38% in non-inmates, p = 0.008). Overall, patients who developed AKI had higher acuity of illness with more requirement of ICU care and mechanical ventilation. Kidney replacement therapy (KRT) was provided to 12.8% of patients. Inpatient mortality occurred in 15.1% of patients and was not different in inmates vs. non-inmates (13.5 vs. 16.3%, p = 0.862). All survivors became independent of KRT, and ~ 1 of 10 survivors had a reduction of eGFR ≥ 25% from baseline by the time of discharge, which was more frequent in inmates vs. non-inmates, 15.6 vs. 2.4%, p = 0.042, respectively. CONCLUSION: Inmates represent a vulnerable population with prevalent comorbidity and susceptibility to COVID-19. When compared to non-inmates with COVID-19, inmates exhibited higher incidence of AKI and, for survivors, less kidney recovery by the time of hospital discharge. Surveillance of long-term sequela of COVID-19 is warranted in this susceptible inmate population.
