Characterising the long-term clinical outcomes of 1190 hospitalised patients with COVID-19 in New York City: a retrospective case series.

OBJECTIVE: To characterise the long-term outcomes of patients with COVID-19 admitted to a large New York City medical centre at 3 and 6 months after hospitalisation and describe their healthcare usage, symptoms, morbidity and mortality. DESIGN: Retrospective cohort through manual chart review of the electronic medical record. SETTING: NewYork-Presbyterian/Columbia University Irving Medical Center, a quaternary care academic medical centre in New York City. PARTICIPANTS: The first 1190 consecutive patients with symptoms of COVID-19 who presented to the hospital for care between 1 March and 8 April 2020 and tested positive for SARS-CoV-2 on reverse transcriptase PCR assay. MAIN OUTCOME MEASURES: Type and frequency of follow-up encounters, self-reported symptoms, morbidity and mortality at 3 and 6 months after presentation, respectively; patient disposition information prior to admission, at discharge, and at 3 and 6 months after hospital presentation. RESULTS: Of the 1190 reviewed patients, 929 survived their initial hospitalisation and 261 died. Among survivors, 570 had follow-up encounters (488 at 3 months and 364 at 6 months). An additional 33 patients died in the follow-up period. In the first 3 months after admission, most encounters were telehealth visits (59%). Cardiopulmonary symptoms (35.7% and 28%), especially dyspnoea (22.1% and 15.9%), were the most common reported symptoms at 3-month and 6-month encounters, respectively. Additionally, a large number of patients reported generalised (26.4%) or neuropsychiatric (24.2%) symptoms 6 months after hospitalisation. Patients with severe COVID-19 were more likely to have reduced mobility, reduced independence or a new dialysis requirement in the 6 months after hospitalisation. CONCLUSIONS: Patients hospitalised with SARS-CoV-2 infection reported persistent symptoms up to 6 months after diagnosis. These results highlight the long-term morbidity of COVID-19 and its burden on patients and healthcare resources.

A double-edged sword: Prolonged detection of SARS-COV-2 in patients receiving cancer directed therapy.

INTRODUCTION: SARS-CoV-2 (S-2) infection duration and its impact on patients with cancer and mild to moderate COVID-19 undergoing cancer-directed therapy (CDT), especially in the underserved population, is not well described. We conducted a retrospective study to analyze S-2 positive (+) patients on CDT to describe the S-2 duration and its impact on CDT. METHODS: Two hundred ninety-nine patients with cancer were tested with nasopharyngeal (NP) S-2 PCR assay at Columbia University Medical Irving Center (CUIMC), a Minority-NCI Community Oncology site, of which 77 (26%) tested positive. We retrospectively analyzed 26 S-2 (+) patients with mild-to-moderate COVID-19 receiving CDT who consented to the study. NP PCR was repeated every 1 to 2 weeks until 2 successive negative (-) PCRs were obtained prior to restarting CDT. Time to 2 (-) PCR and serology results were recorded. Cycling thresholds (Ct) were obtained for S-2 specific targets and represented an indirect measure of viral load. RESULTS: Demographics of N = 26 patients are: Hispanic (N = 17, 65%), Black (N = 1, 4%), White (N = 7, 27%), and undeclared (N = 1, 4%). Among the tumor histologies represented, gastrointestinal (N = 9, 35%), breast (N = 5, 19%), and sarcoma (N = 3, 12%) were most common. Median time to 2 (-) PCR was 32 days. Twenty patients required greater than 14 days to achieve 2 sequential (-) swabs. CDT was delayed in 21 patients (81%) of whom three experienced disease progression, likely attributed to an interruption in CDT, which was delayed by a mean of 53 days. Interestingly, nine (41%) patients had Ct values greater than 34 for the pan SARS target and seven (32%) patients had Ct values greater than 34 for the SARS-COV-2 target. Sixteen of 16 patients on CDT, tested positive for IgG antibodies at the time of consent, despite protracted viral detectability by NP PCR. CONCLUSION: Patients receiving CDT appear to have prolonged detectable S-2 by PCR, which can lead to interruption of CDT and POD in patients. We believe and recommend that patients with asymptomatic to mild COVID-19 and aggressive malignancies are at greatest risk for cancer related morbidity and mortality due to CDT cessation and should be considered for continued CDT without interruption. Ct values and serology testing are tools that can help identify those patients on CDT who may be at greatest risk of worsening COVID-19 or of spreading S-2.
