Screening testing for SARS-CoV-2 upon admission to rehabilitation hospitals in a high COVID-19 prevalence community.

Background While planning for the care of coronavirus disease 2019 (COVID-19) patients during the pandemic crisis has dominated the focus of leaders of inpatient rehabilitation facilities (IRFs), patients with injuries/illnesses unrelated to COVID-19 continue to need inpatient rehabilitation admission. To maintain a safe environment for all patients and staff, we established an admission screening plan of testing for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) to determine the presence of asymptomatic patients who were infected with the virus upon admission. Objective To determine the prevalence of patients who test positive for SARS-CoV-2 but were presumed to be COVID-19 negative at the time of admission to IRF in New Jersey. Design Retrospective analysis of SARS-CoV-2 testing results. Setting Four freestanding IRFs in New Jersey operated as one system. Patients All (N = 103) patients sequentially admitted from 4 to 27 April 2020 with no symptoms or evidence of COVID-19 disease at the time of transfer from the acute hospital. Interventions Specimens were collected for SARS-CoV-2 analysis at the time of admission to the IRF and patients were monitored for subsequent symptom development over the next 14 days. Main Outcome Measures Results of SARS-CoV-2 testing upon admission and evidence of development of clinical signs or symptoms of COVID-19. Results Seven asymptomatic persons (6.8% of admissions) without clinical signs/symptoms of COVID-19 tested positive on admission. Of these, five developed symptoms of COVID-19, with a mean onset of 3.2 (range of 2-5) days. Five additional patients became symptomatic and tested positive within the next 3 to 10 days (mean of 5.2 days). Overall, 11.6% of admissions (12/103) had a positive test within 14 days of admission. Conclusions Admission testing to postacute centers for SARS-CoV-2 can help identify presymptomatic or asymptomatic individuals, especially in areas where COVID-19 is prevalent. Negative results, however, do not preclude COVID-19 and should not be used as the sole basis for patient management decisions.
