Clinical Characteristics of Hospitalized Patients With COVID-19: A Retrospective Cohort Study in Pakistan.

BACKGROUND: The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) caused a global pandemic of severe upper respiratory tract infections known as COVID-19. This single-center study aimed to investigate the demographics, comorbidities, symptoms, and disease severity of COVID-19 patients in Pakistan. METHODS: A retrospective descriptive study was conducted at the Pakistan Kidney and Liver Institute and Research Center from April 2020 to August 2020. A total of 430 PCR-positive COVID-19 patients were categorized into symptomatic and asymptomatic groups. The symptomatic group was further classified into severe and non-severe subgroups. Patients' demographics, comorbid conditions, presenting symptoms, laboratory parameters, and clinical outcomes were assessed in these two subgroups. Statistical tests were applied to determine significant differences. RESULTS: A total of 430 patients with COVID-19 presented in our center, of whom 334 (78%) were symptomatic and included in the study. Severe disease was observed in 83 (24.8%) symptomatic patients, with a male predominance (75.9%) and higher mean age (61.7 ± 13.2). Travel to high-risk destinations (p < 0.002) and close contact with COVID-19 patients (p < 0.001) were significant risk factors. Major comorbid conditions included diabetes mellitus (30.5%) and hypertension (39.8%). Frequent symptoms included fever (71.8%), cough (68.8%), dyspnea (53.8%), and myalgias (35.9%). Higher C-reactive protein (median = 12.76 vs. 1.45, p = 0.001), ferritin (median = 996.70 vs. 628, p = 0.004), and D-dimers (median = 1121 vs. 439.50, p = 0.009) were noted in severe vs non-severe disease. Lymphopenia was more prevalent in severe vs. non-severe disease (83.1% vs. 14.3% p-value = 0.033). More deaths (28.9%) and ICU admissions (53%) with a prolonged hospital stay (median = 25 days, IQR = 16.0-31.0) were noted in the severe group. CONCLUSION: This retrospective study provides insights into the clinical characteristics and outcomes of COVID-19 patients. Age, male gender, comorbidities, and specific symptoms were associated with disease severity. Inflammatory markers, including D-dimers, ferritin, and CRP, were elevated in severe cases. These findings contribute to a better understanding of COVID-19 and may aid in clinical management and decision-making for patients affected by the disease.

Factors affecting warfarin-related knowledge and INR control of patients attending physician- and pharmacist-managed anticoagulation clinics.

OBJECTIVES: To assess the anticoagulation knowledge and international normalized ratio (INR) control among patients on warfarin. METHODS: A cross-sectional study with 156 randomly sampled patients from physician- (non-medication therapy adherence clinic [non-MTAC]) and pharmacist (MTAC)-run anticoagulation clinics using a validated interviewer-administered questionnaire. Patients' INR readings from 2008 to 2010 were recorded. RESULTS: Patients on warfarin scored an average of 66.5% ± 36.0% for their knowledge on how warfarin works, 42.9% ± 44.9% for interaction between warfarin and alcohol, and 49.2% ± 21.1% for adverse effects. No significant differences were found between MTAC and non-MTAC patients on their knowledge. There was a negative correlation between patients' knowledge and age (P = .001, r (s) = -.293) and a positive correlation between patients' knowledge and education level (P = .001, r (s) = .365). MTAC patients were found to have better INR control than non-MTAC when compared for mean percentage days in range (63.4% ± 18.9% vs 52.5% ± 18.2%; P = .006) and mean percentage visits in range (58.8% ± 17.9% vs 46.8% ± 18.6%; P = .001). CONCLUSIONS: MTAC patients were found to have better INR control compared to non-MTAC patients. A joint cooperation between physicians, pharmacists, and nurses should exist to achieve desired therapeutic outcomes.
