Telephone Monitoring of Isolated Patients With Suspected COVID-19 Disease in Primary Care: Prospective Cohort Study.

Objective: Isolation of suspected cases of COVID-19 has been shown effective in reducing disease transmission and monitoring these patients from primary care allows to detect complications. The objective of this study is to determine the evolution of a cohort of patients with suspected COVID-19, and to analyse the factors associated with hospital admissions due to their unfavourable evolution. Methods: Prospective cohort study. A cohort of 166 patients with COVID-19 symptoms was selected and was followed-up by telephone calls during 14 days of home isolation. Results: By the end of the follow-up, a hospital admission had taken place in 14.7% of patients. The mean survival time until admission among diabetics was 12.6, 10.9 days for chronic kidney diseases, and 9.3 days in immunocompromised patients. Immunosuppression was a risk factor for admission over 50 years of age. Conclusion: Hospital admissions for suspected cases of COVID-19 are associated with diabetes, chronic kidney disease, and immunosuppression. Telephone monitoring of these patients from primary care allows for home isolation and early detection of disease complications.

Evolution of a Cohort of COVID-19 Infection Suspects Followed-Up from Primary Health Care.

Diagnosis and home follow-up of patients affected by COVID-19 is being approached by primary health care professionals through telephone consultations. This modality of teleconsultation allows one to follow the evolution of patients and attend early to possible complications of the disease. The purpose of the study was to analyze the evolution of a cohort of patients with suspected SARS-CoV-2 disease followed by primary care professionals and to determine the factors that are associated with hospital admission. A prospective cohort study was carried out on 166 patients selected by consecutive sampling that showed symptoms compatible with COVID-19. The follow-up was approached via telephone for 14 days analyzing hospitalization and comorbidities of the patients. There were 75% of the hospitalized patients that were male (p = 0.002), and 70.8% presented comorbidities (p < 0.001). In patients with diabetes, the risk of hospitalization was 4.6-times larger, in hypertension patients it was 3.3-times, those suffering from renal insufficiency 3.8-times, and immunosuppressed patients 4.8-times (IC 95%: 1.9-11.7). In 86.7% of the cases, clinical deterioration was diagnosed in the first seven days of the infection, and 72% of healing was reached from day seven to fourteen. Monitoring from primary care of patients with COVID-19 allows early diagnosis of clinical deterioration and detection of comorbidities associated with the risk of poor evolution and hospital admission.
