Elderly COVID-19 patients have been associated with worse outcomes and have been presented with the highest mortality rate. However, studies on the clinical features and the differences between critical and non-critical elderly COVID-19 patients in Indonesia and even other countries are still lacking and rare. In this retrospective study, the epidemiological and clinical features of critical and non-critical elderly COVID-19 patients admitted to Udayana University Academic Hospital between April 2020 and March 2021 were analyzed and then compared. Of the 280 medical records analyzed, 60.7% were male and the median age was 65.0 years old. Based on the medical records, 18.2% of elderly patients met our criteria of critical patients. The most common symptoms presented in both category upon admission included fever and coughing. The most common comorbidity found in critical patients was heart disease and hypertension in non-critical patients. Laboratory results differences included leukocytes, neutrophils, lymphocytes, Neutrophil-to-Lymphocyte Ratio, platelets, SGOT, SGPT, and urea. Only 9.9% of critical patients and 6.1% of non-critical patients were given antiviral therapy. In contrast, 68.6% of critical patients and 76% of non-critical patients were given antibiotics. The mortality rate in critical patients was 70.6% and 0.4% in non-critical patients. Based on the results, a multimodal approach in the treatment of elderly COVID-19 patients is very essential. The higher mortality rate in elderly patients should be able to be reduced by giving early and timely antiviral therapy with the addition of effective choice of drugs.

The increase in mask waste and a lack of understanding about the management of single-use mask waste raises the potential for environmental pollution and COVID-19 transmission. Aim: This study aimed to assess the level of understanding of medical mask waste management and strengthening health protocols in controlling COVID-19 infection in Banjar Purwa Santhi, Benoa, Badung Regency. Methodology and Results: A cross-sectional method and descriptive study design were used with a sample of 100 respondents selected via stratified sampling. The research and service activities at Banjar Purwa Santhi Benoa include public campaign and assessment of the level understanding of medical mask waste management. Based on univariate analysis, 91% of respondents know that mask waste contains hazardous and toxic substances. If mask waste is disposed carelessly, 98% of respondents stated that it can pollute the environment, and 98% of respondents also stated that it has the potential to become a means of transmitting COVID-19. However, 85% of respondents disposed of the masks in the household trash. Conclusion, significance and impact study: Respondents had a good level of knowledge about health protocols and mask waste management but have not separated masks from household waste. By holding the community service activity, it is hoped that changes in community behavior will occur.

Impacting the community does not always mean creating exponential growth, it can also mean bringing small and sustainable changes to improve people’s quality of life. Living in a developing country, we had a first-hand experience of seeing life in underprivileged communities. This experience expanded our desire to serve communities around us. However, due to the emergence of COVID-19 in Indonesia, most of the plans to contribute to our community were halted. Strict outbreak control measures, which restricted people’s mobility, prohibited visits to these underprivileged communities.
