A comprehensive surveillance, prevention and control of the Coronavirus Disease 2019 model of large enterprises Phitsanulok Province, year 2021

Abstract

          Due to covid19 pandemic worldwide, Thailand was similarly affected. Most of the outbreaks are clusters from populations that have moved back to their domicile. This led to rapid transmission. Ongoing outbreaks occurred in both communities and large enterprises, especially in the 4th wave (January-February 2022). This research and development study aims to prevent the spread of covid-19 and evaluate the prevention and control surveillance system of large enterprises in the Phitsanulok province since 2021. Firstly, we identified its context and major problems. To collect quantitative data, we used a proportional stratified random sampling technique by sector and estimated with the Krejcie & Morgan method that at least 600 samples were needed. Meanwhile, we conducted a focus group discussion to gather qualitative data. Secondly, we developed a new surveillance system and let stakeholders of the enterprise determine about the feasibility and propriety. Finally, the feasibility, utility, propriety, and accuracy standards of this surveillance system were evaluated by 7 experts. We used two semi-structured questionnaires for interviewing in Steps 1 and 3 and analyzed quantitatively using descriptive statistics, including percentage, mean, and standard deviation. We also used content analysis for qualitative data from focus group discussions. A total of 600 people was interviewed for the first step, including managers and employees. Most of them (93.7%) were female with an average age of 36.5 years. We found good opinion for performance (mean = 3.83 - 4.27) and practice (mean = 3.97 - 4.27) and fair opinions for roles and participation (mean = 3.29 - 3.58). After the new surveillance system were developed, 100% of stakeholders agreed about the feasibility and propriety. We also found good opinion for 4 standards from 7 experts, while topics of consistency with the context, problems, and policy received the highest average score.
