Objectives: The Indonesian Ministry of Health launched isoniazid preventive therapy (IPT) in 2016, with general practitioners (GPs) at the frontline of this program. However, the extent to which GPs have internalized this program remains uncertain. The aim of this study was to identify the knowledge and attitudes of GPs towards the IPT program in Indonesia. Methods: This study used an online, self-administered questionnaire distributed via e-mail and social messaging services. A logistic regression model was employed to identify the explanatory variables influencing the level of knowledge and attitudes toward IPT among GPs in Indonesia. An empirical analysis was conducted separately for each response variable (knowledge and attitudes). Results: Of the 418 respondents, 128 (30.6%) had a good knowledge of IPT. Working at a public hospital was the only variable associated with good knowledge, with an adjusted odds ratio (aOR) of 1.69 (95% confidence interval [CI], 1.02 to 2.81). Furthermore, 279 respondents (66.7%) had favorable attitudes toward IPT. In the adjusted logistic regression analysis, good knowledge (aOR, 0.55; 95% CI, 0.34 to 0.89), 1-5 years of work experience (aOR, 2.09; 95% CI, 1.21 to 3.60), and having experienced IPT training (aOR, 0.48; 95% CI, 0.25 to 0.93), were significantly associated with favorable attitudes. Conclusions In general, GPs in Indonesia had favorable attitudes toward IPT. However, their knowledge of IPT was limited. GPs are an essential element of the IPT program in the country, and therefore, adequate information dissemination to improve their understanding is critical for the long-term viability and quality of the IPT program in Indonesia.

To assess healthcare workers' knowledge of novel coronavirus disease 2019 (COVID-19) in the early phase of the outbreak in Indonesia. Methods: A cross-sectional survey was conducted in 12 hospitals in Indonesia from March 6 to March 25, 2020. Healthcare workers' knowledge on COVID-19 was assessed, and demographic data, workplace characteristics, and medical professional characteristics as well as the current local situation of COVID-19 were collected. To characterize determinants associated with knowledge, a logistic regression analysis was employed. Results: Out of 288 healthcare workers who completed the interview-assisted questionnaire, 149 (51.7%) respondents had a good knowledge. Nurses and other types of healthcare workers had lower odds of having good knowledge compared to doctors: adjusted odds ratio (aOR): 0.38; 95% CI: 0.20-0.72 and aOR: 0.31; 95% CI: 0.13-0.73, respectively. Compared to healthcare workers who had medical practice experience less than 5 years, those who had worked for more than 10 years had lower knowledge (aOR: 0.43; 95% CI: 0.20-0.90). Healthcare workers who worked in the infection department had higher knowledge compared to those in the emergency room (aOR: 14.33; 95% CI: 3.67-55.88). Conclusions: The knowledge of COVID-19 among surveyed healthcare workers was relatively low. The COVID-19 response in Indonesia will require further education and enhancement of the capacity of healthcare workers in the emergency room where COVID-19 patients may be treated the earliest.
