Sumario: | BACKGROUND: Routine testing of hemodialysis patients for COVID-19 (outside of those identified as “at risk” based on regional practice) is not universally recommended. However, there is variability in the clinical presentation of COVID-19; patients may experience symptoms that do not meet regional criteria for testing and some patients with active infection may be asymptomatic. To avoid missing individuals who are infected, consideration could be made for regular screening, particularly among those residing in areas with evidence of community spread. OBJECTIVE: To describe the clinical characteristics, symptom burden, and COVID-19 status in a cross-section of hemodialysis patients residing in areas with evidence of community spread. DESIGN: Cross-sectional study. SETTING: Three hemodialysis units in a large tertiary care facility in Nova Scotia, Canada. PATIENTS: In-center hemodialysis patients who resided in areas with evidence of community transmission at the time of the study. METHODS: All dialysis patients (irrespective of whether or not they resided in areas with community spread) completed a standard “at-risk” questionnaire for COVID-19 based on (1) 2 or more of new or worsening cough, fever greater than 38°C, sore throat, headache, runny nose/new or acute respiratory illness consistent with infection or (2) any one of close contact with a known/suspected case, travel outside of the province or residence in a facility with an outbreak prior to entry into the dialysis unit at each treatment. Patients residing in areas with evidence of community spread were swabbed for SARS-CoV-2 over a 1-week period (May 1-7, 2020) using a combined oropharyngeal/nares swab irrespective of whether or not they were identified as “at-risk.” MEASUREMENTS: Baseline characteristics of patients were acquired using electronic records. In addition to the “at-risk” questionnaire, patients answered “yes” or “no” to any of the following symptoms at the time of the swab (sneeze, fatigue, myalgia, nausea/vomiting, diarrhea, malaise, abdominal pain, loss of taste, and loss of smell). RESULTS: Of the 334 patients receiving dialysis at the time of the study, 133 resided in areas with evidence of community transmission and 104 consented for the study. No patients met our regional criteria for being “at-risk” and no patients reported cough, sore throat or fever at the time of swab. Many other symptoms were noted, including sneezing (24%), fatigue (16%), myalgias (11%), nausea/vomiting (11%), loss of taste (4%), and loss of smell (4%). Overall, 100% of swabs performed for this study were negative for SARS-CoV-2. LIMITATIONS: Single-center study, and the daily new case rate was exceedingly low (4-14) at the time of the study, emphasizing that the findings are not generalizable to areas of higher prevalence of SARS-CoV-2. CONCLUSIONS: In this study of hemodialysis patients residing in areas with community spread who otherwise did not meet symptom criteria for being “at-risk,” we did not identify any individual who tested positive for SARS-CoV-2. Future studies are needed to examine the utility of routine testing for COVID-19 (outside of those who are “at-risk”) in areas of higher disease prevalence. TRIAL REGISTRATION: Not applicable as this is not a clinical trial. |
