【 摘 要 】

Background: Coronavirus disease (COVID-19) is a global outbreak caused by novel SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2). Study aims to evaluate knowledge and practices of healthcare workers (HCW) regarding infection prevention and control of corona virus disease Material and methods: A cross sectional validation study was conducted. Study was conducted at department of Medicine, Pakistan Ordinance Factory Hospital, Wah Cantt. Study duration was 2 months (May 2020-June2020)A sample size of 217 HCW was calculated using WHO calculator. HCW were selected through non probability sampling (consecutive). Ethical permission was taken and research consent was signed by each participant. SPSS version 24 was used for analysis purpose. Post stratification fissure exact and chi-square test was applied. We found p value ≤0.05 as statistically significant. Results: Total 217 HCW were included in our study. Out of them, 85 (39.2%) were male and 132 (60.8%) were female in our study. Mean age of HCW was 34.5±2.4SD. In knowledge assessment majority of HCW had fair knowledge (46.5%), followed by good (30%) and poor knowledge (23.5%) regarding corona virus associated infection control and prevention. In practice assessment, among all those, 38.2% HCW showed better practices while 61.8% showed poor practices. Knowledge is significantly associated with virus transmission mode (p = 0.00), close contact (p = 0.000), protection from COVID-19 in triage area (p = 0.000), wearing PPE (p = 0.000) etc. Conclusion: Corona virus disease is a major challenge in resource limited countries. Healthcare workers showed relatively improved knowledge and practices regarding infection prevention and control in this COVID-19 Pandemic.
