Universal COVID-19 testing and a three-space triage protocol is associated with a nine-fold decrease in possible nosocomial infections in an inpatient psychiatric facility.

In May of 2020, the Substance Abuse and Mental Health Service Administration (SAMSA) issued guidelines for state psychiatric hospitals, recommending that these facilities adopt universal testing for COVID-19 and "three-space" triage protocols for dedicated COVID-19 positive, negative, and quarantine spaces to mitigate the risk of nosocomial infection. The Westchester Behavioral Health Center of New York Presbyterian Hospital (WBHC-NYP) adopted a comprehensive infection control protocol consistent with these recommendations in April, 2020. We reviewed the records of 1,139 patients treated on the inpatient service at WBHC-NYP between March 14th and June 10th, 2020, dates corresponding to the first COVID-19 surge in the New York City metropolitan region. The incidence of detected nosocomial or possible nosocomial infections before and during the implementation of the protocol was 0.096 (16/167), or 0.96 infections per 10 at-risk patients. The incidence of nosocomial or possible nosocomial infections after complete implementation was 0.0110 (2/182), or 1.1 infections per 100 at-risk patients. The difference in incidence between the two time points was statistically significant (p<.0003) and represents a 9-fold decrease.  Our findings support the institutional use of a combined testing and space allocation protocol to mitigate risk of outbreaks in confined settings.

COVID-19 infection rates in patients referred for psychiatric admission during a regional surge: The case for universal testing.

Some psychiatric hospitals have instituted mandatory COVID-19 testing for all patients referred for admission. Others have permitted patients to decline testing. Little is known about the rate of COVID-19 infection in acute psychiatric inpatients. Characterizing the proportion of infected patients who have an asymptomatic presentation will help inform policy regarding universal mandatory versus symptom-based or opt-out testing protocols. We determined the COVID-19 infection rate and frequency of asymptomatic presentation in 683 consecutively admitted patients during the surge in the New York City region between April 3rd, 2020 and June 8th, 2020. Among these psychiatric inpatients, there was a 9.8 % overall rate of COVID-19 infection. Of the COVID-19 infected patients, approximately 76.1 % (51/67) either had no COVID-19 symptoms or could not offer reliable history of symptoms at the time of admission. Had they not been identified by testing and triaged to a COVID-19 positive unit, they could have infected others, leading to institutional outbreak. These findings provide justification for psychiatric facilities to maintain universal mandatory testing policies, at least until community infection rates fall and remain at very low levels.

Frequency and profile of objective cognitive deficits in hospitalized patients recovering from COVID-19.

Early reports and case series suggest cognitive deficits occurs in some patients with COVID-19. We evaluated the frequency, severity, and profile of cognitive dysfunction in patients recovering from prolonged COVID-19 hospitalization who required acute inpatient rehabilitation prior to discharge. We analyzed cross-sectional scores from the Brief Memory and Executive Test (BMET) in a cohort of N = 57 COVID-19 patients undergoing inpatient rehabilitation, calculating the frequency of impairment based on neuropsychologist diagnosis and by age-normed BMET subtests. In total, 43 patients (75%) were male, 35 (61%) were non-white, and mean age was 64.5 (SD = 13.9) years. In total, 48 (84%) were previously living at home independently. Two patients had documented preexisting cognitive dysfunction; none had known dementia. Patients were evaluated at a mean of 43.2 (SD = 19.2) days after initial admission. In total, 50 patients (88%) had documented hypoxemic respiratory failure and 44 (77%) required intubation.  Forty-six patients (81%) had cognitive impairment, ranging from mild to severe. Deficits were common in working memory (26/47 [55%] of patients), set-shifting (21/44 [47%]), divided attention (18/39 [46%]), and processing speed (14/35 [40%]). Executive dysfunction was not significantly associated with intubation length or the time from extubation to assessment, psychiatric diagnosis, or preexisting cardiovascular/metabolic disease. Attention and executive functions are frequently impaired in COVID-19 patients who require acute rehabilitation prior to discharge. Though interpretation is limited by lack of a comparator group, these results provide an early benchmark for identifying and characterizing cognitive difficulties after COVID-19. Given the frequency and pattern of impairment, easy-to-disseminate interventions that target attention and executive dysfunctions may be beneficial to this population.
