Psychological impact amongst patients with COVID-19 in Perak state.

INTRODUCTION: Psychological distress had been documented since the beginning of the COVID-19 outbreak in 2019. The aim of the study is to describe the psychological impact among those who were hospitalized for COVID-19 infection within 6 months after being discharged from the hospital. The psychological impact in this study is defined as depression, anxiety, and stress. MATERIALS AND METHODS: This was a cross-sectional study conducted from July 2020 till August 2021 in a regional state hospital, north of Malaysia. All patients requiring hospitalization for COVID-19 were approached within the first 2 weeks after admission to administer the Depression, Anxiety and Stress Scale - 21 Items (DASS-21) scale. Follow-up phone calls were made within 3 months of discharged to enquire about the DASS-21 items as well as the Impact of Event Scale-Revised (IES-R) scale items. Participants above the age of 18 and technology savvy to answer an online questionnaire were recruited for the study. We excluded participants with a known history of psychotic disorder from the study. We utilised the DASS-21 to screen for depression, anxiety, and stress, as well as the IES-R to identify symptoms of post-traumatic stress disorder. Participants could answer the questionnaires in either English or Bahasa Malaysia. For comparison of two categorical data, a chi-square was applied. A univariate analysis was first conducted and all variables with a p ≤0.3 was then entered into the multivariate analysis for the final output. Other than the univariate analysis, all other p values <0.05 were considered to be statistically significant. All data collected were tabulated and analysed in the SPSS v21.0 system. RESULTS: A total of 306 out of 696 COVID-19 patients responded. The mean age for the participants was 31.69 (SD:11.19) years old. From the total, 54.2% were ladies, 78.8% were Malay, 50.7% were unmarried, 55.2% had higher education, and 67.6% were employed at the time of the survey. We found 20.5% of the participants were depressed, 38.9% had moderate anxiety, and 17.3% were stressed. From the total, 31.7% of the participants were deemed to have had some symptoms of post-traumatic stress disorder (PTSD) ranging from mild to severe. From the final multivariate analysis, it was found that depression (p=0.02) had a 2.78 times likeliness of having PTSD, anxiety (p<0.001) had a 3.35 times likeliness of having PTSD and stressed patients (p=0.02) 2.86 times likeliness of having PTSD when compared to those without PTSD. CONCLUSION: Patients reported to suffer from symptoms of PTSD and might benefit from psychological interventions to mitigate the impact in the long run.

Production Resumption Analysis for Different Industries by K-means Clustering

At the beginning of 2020, the COVID-19 suddenly struck, which had a great impact on industrial production, causing most companies to shut down. To further study the work and production resumption progress for industrial users, this paper analyzes the electricity consumption data from a total of 200 users in four industries including heavy industries, general industry and commerce, agricultural production industries, and agricultural irrigation and drainage industries in a city in Eastern China before and after the Spring Festival and pandemic. K-means clustering with Silhouette Coefficient is adopted as the primary tool to analyze the resumption thresholds for different industries. Combined with these thresholds, the industry resumption rate curve is further drawn, and the resumption rate of each industry one month before and after the Spring Festival is analyzed to provide support for in-depth analysis of the impact of the pandemic on different industries. © 2020 IEEE.
