    Introduction: Since the beginning of the pandemic, factors associated with mortality in patients with corona virus infection disease 2019 (COVID-19) have been investigated. Comorbidities and increased age have been frequently reported to be associated with mortality. We aimed to evaluate the factors associated with unfavorable outcome of patients with COVID-19 at an early period of the pandemic. Methodology: This single center, retrospective, observational study was conducted among laboratory confirmed COVID-19 patients hospitalized between March 11 and May 5, 2020, at Umraniye Training and Research Hospital, Istanbul, Turkey. The effects of the severity of illness, comorbidities, symptoms, and laboratory findings on the clinical outcome were evaluated. Factors associated with unfavorable outcome (necessity of mechanical ventilation or death) were examined using Cox proportional hazards models. Results: Out of a total of 728 patients, 53.8% were men and median age 54 years. The 30-day mortality rate was 4.9% among all hospitalized patients. A logistic regression model identified six predictors of unfavorable clinical outcome: age, severity of illness, the numbers of comorbidities, lymphopenia, high levels of C-reactive protein, and procalcitonin. Conclusions: The mortality rate was lower among the patients with COVID-19, hospitalized during the early period of the pandemic. Older age, higher severity score on admission, the numbers of comorbidities, higher levels of C-reactive protein, procalcitonin, and lymphopenia were identified to be associated with unfavorable outcome of the hospitalized patients with COVID-19.

    Medication reconciliation service in hospitalized patients with infectious diseases during coronavirus disease-2019 pandemic: An observational study
    (2023-08-01) ENVER, CÜNEYD; ERTÜRK ŞENGEL, BUKET; SANCAR, MESUT; KORTEN, VOLKAN; OKUYAN, BETÜL; ENVER C., ERTÜRK ŞENGEL B., SANCAR M., KORTEN V., OKUYAN B.
    Objectives: To determine the prevalence and type of medication discrepancies and factors associated with unintentional discrepancies and identify the rate of hospital readmission and emergency service visit within 30 days after discharge among hospitalized patients with infectious diseases and receiving clinical pharmacist-led medication reconciliation during the coronavirus disease-2019 (COVID-19) pandemic. Materials and Methods: This observational study was conducted in the internal medicine and infectious diseases wards of a tertiary university hospital between July 2020 and February 2021 among hospitalized adult patients with infectious diseases. Medication reconciliation service (including patient counseling) was provided in person or by telephone. The number and type of medication discrepancies detected during the medication reconciliation services, the acceptance rate of pharmacists’ recommendation, and factors associated with having at least one unintentional medication discrepancy at admission were evaluated. At follow-up, hospital readmission and emergency service visit within 30 days after discharge were assessed by telephone. Results: Among 146 patients, 84 (57.5%) had at least one unintentional discrepancy at admission. Only three unintentional discrepancies were determined in three patients at hospital discharge. All the pharmacists’ recommendations for medication discrepancies were accepted by the physicians. Having COVID-19 [odds ratio (OR): 2.25, 95% confidence interval (CI): 1.15-4.40; p<0.05], being at a high risk for medication error (OR: 2.01, 95% CI: 1.03-3.92; p<0.05), and higher number of medications used at home (OR: 1.41, 95% CI: 1.23-1.61; p<0.001) were associated with having at least one unintentional discrepancy at admission. The rates of 30 day hospital readmission and admission to the emergency medical service were 12.3% and 15.8%, respectively. Conclusion: Medication reconciliation service provided by in-person or by telephone was useful for detecting and solving unintentional medication discrepancies during the COVID-19 pandemic.
