RESUMO
INTRODUCTION: Although COVID-19 has entered the endemic phase, individuals infected with COVID-19 are required to adhere to home quarantine measures. By exploring the public's knowledge and attitude towards recommended home quarantine measures, their readiness in containing potential COVID-19 outbreak can be determined. This study aimed to assess the public knowledge and attitude towards home quarantine instructions and their association with history of COVID-19 infections. METHODS: This was a web-based cross-sectional study conducted among the public in Malaysia between August to October 2022. All Malaysian adults over 18 years of age were included. Knowledge on home quarantine instructions and COVID-19 warning signs were measured using "True," "False," or "I'm not sure", while attitude towards home quarantine instructions was measured using a five-point Likert Scale. The questionnaire was initially constructed in English and then translated into the national language, Bahasa Malaysia. Face and content validation were performed. The internal consistency of the questionnaire was found to be satisfactory. RESULTS: 1,036 respondents were analyzed, comprised mostly of females (743, 71.6%) with a history of COVID-19 (673, 64.9%). In the knowledge domain, more than 80% of the respondents answered 9 out of 11 home quarantine instructions statements correctly. 457 (44.1%) were unaware or unsure about the minimum distance of the infected individual's bed from the rest of the occupants in a shared bedroom. The respondents reported relatively weaker knowledge in identifying uncommon warning signs of COVID-19 deterioration, including anuria (162, 44.5%), ingestion problems (191, 52.5%), and immobility (195, 53.6%). In the attitude domain, more than 90% of respondents answered correctly in 8 out of 9 questions. Respondents with a previous history of COVID-19 infections had better knowledge than COVID-19 infection-naïve individuals towards both home quarantine instructions and COVID-19 warning signs. CONCLUSION: Most respondents had good knowledge and attitude towards home quarantine instructions, with those previously infected with COVID-19 showing greater awareness of uncommon warning signs. However, there was a notable lack of awareness regarding physical distancing within shared rooms, appropriate disinfectant use and mobility limitation within the household. This study highlights the knowledge gaps to be improved in future educational campaigns.

BACKGROUND: Children with intravenous immunoglobulin (IVIG) resistant Kawasaki disease (KD) are at higher risk of developing coronary artery (CA) aneurysm. Early identification of high-risk patients using a predictive tool would allow for earlier interventions to prevent cardiac complications. METHODS: Children with KD who were admitted to five selected hospitals in Malaysia between 2008 and 2018 and received 2â¯g/kg of IVIG within 10â¯days from the onset of illness were included. Predictors of IVIG resistance in KD were determined using multiple logistic regression analysis. An optimal cut-off point was set using receiver operative characteristic curve and a final multiple logistic regression analysis was performed entering these cut-off points. A new scoring system was constructed. RESULTS: A total of 276 patients were included. IVIG resistance occurred in 9.1â¯% of them. Total bilirubin [OR 7.37; 95â¯% CI (2.18, 24.83)], male sex [OR 0.34; 95â¯% CI (0.10, 1.19)], C-reactive protein (CRP) [OR 0.17; 95â¯% CI (0.02, 1.38)] and neutrophils [OR 0.25; 95â¯% CI (0.05, 1.21)] were found to be significant predictors for IVIG resistance. The findings led to the development of a new predictive tool called the Hibiscus score, which scored 1 point each for neutrophils ≥60â¯%, CRP ≥80â¯mg/L, and male sex, while total bilirubin ≥9.4⯵mol/L scored 2 points. A cut-off point of ≥4 with this prediction score yielded a sensitivity of 78.9â¯% and specificity of 80.5â¯%, with area under the curve of 0.835 [95â¯% CI (0.752, 0.919)]. CA aneurysms occurred in 6.7â¯% of IVIG responders and 32â¯% of IVIG-resistant children (pâ¯<â¯0.001). CONCLUSION: The findings suggest that the Hibiscus score has a higher predictive power than the existing scoring systems for IVIG resistance in children with KD in Malaysia. However, external validation is required to enable its use to guide treatment decisions.
RESUMO
Hepatitis C self-testing (HCVST) is emerging as an additional strategy that could help to expand access to HCV testing. We conducted a study to assess the usability and acceptability of two types of HCVST, oral fluid- and blood-based, among the general population and men who have sex with men (MSM) in Malaysia. An observational study was conducted in three primary care centres in Malaysia. Participants who were layman users performed the oral fluid- and blood-based HCVST sequentially. Usability was assessed by calculating the rate of errors observed, the rate of difficulties faced by participants as well as inter-reader (self-test interpreted by self-tester vs interpreted by trained user) and inter-operator concordances (self-test vs test performed by trained user). The acceptability of HCV self-testing was assessed using an interviewer-administered semi-structured questionnaire. Participants were also required to read contrived test results which included "positive", "negative", and "invalid". There was a total of 200 participants (100 general population, 100 MSM; mean age 33.6 ± 14.0 years). We found a high acceptability of oral fluid- and blood-based HCVST across both general population and MSM. User errors, related to timekeeping and reading within stipulated time, were common. However, the majority of the participants were still able to obtain and interpret results correctly, including that of contrived results, although there was substantial difficulty interpreting weak positive results. The high acceptability of HCVST among the participants did not appreciably change after they had experienced both tests, with 97.0% of all participants indicating they would be willing to use HCVST again and 98.5% of them indicating they would recommend it to people they knew. There was no significant difference between the general population and MSM in these aspects. Our study demonstrates that both oral fluid- and blood-based HCVST are highly acceptable among both the general population and MSM. Both populations also showed comparable ability to conduct the tests and interpret the results. Overall, this study suggests that HCVST could be introduced as an addition to existing HCV testing services in Malaysia. Further studies are needed to establish the optimal positioning of self-testing alongside facility-based testing to expand access to HCV diagnosis in the country.
RESUMO
COVID-19 self-testing is essential for enabling individuals to self-care, screen themselves and, if positive, isolate themselves. Since 2021, COVID-19 self-tests have been extensively used in high-income countries, however, their programmatic implementation in low- and middle-income countries has been delayed. An implementation pilot, mixed-methods study, was conducted in four industrial manufacturing companies, in Kedah State between November 2022 and May 2023. Participants were asked to take COVID-19 self-tests home for themselves and their household members and to use the tests according to national guidelines. At enrolment and at the end of the study, participants completed an online sociodemographic, knowledge and satisfaction survey. Data were cleaned and analysed using SPSS Statistics V28.0. Qualitative data were collected through semi-structured interviews and focus group discussions. Thematic analysis was conducted. A total of 1768 employees from four manufacturing industries enrolled in the pilot, representing 60% of the total employees and more than 50% of employees at each site. There were 40 COVID-19-positive cases detected in participants from the manufacturing industries, and 100 positive household members. Participants reported 27 invalid test results. Individuals aged 30 or less [adjusted odds ratio (AOR): 2.65; 95% CI: 1.63 to 4.31; p<0.001] and males (AOR: 1.54; 95% CI: 1.09 to 2.17; p = 0.014) showed a significant higher likelihood of self-testing compared to older and female participants. Additionally, individuals who received three or more doses of a COVID-19 vaccine had higher odds of using self-tests (OR 1.56 (95% CI: 1.03 to 2.36, p = 0.037)). There was a significant increase in participants' knowledge on how to correctly collect a self-sample using a nasal swab from 36,9% at baseline to 43,6% post-implementation (p = 0.004) and correct interpretation of a positive result from 80,5% at baseline to 87,6% post-implementation (p<0.001). Furthermore, there was a notable increase in the correct understanding of actions following a positive result, especially regarding self-isolation, which rose from 59.1% to 71.9% (p<0.001). A total of 44 SSIs, and 4 FGDs with a total of 14 participants, were performed. The five main themes explored were: 1) previous experiences with COVID-19, 2) COVID-19 ST experiences during the pilot study, 3) advantages of COVID-19 ST, 4) feelings related to COVID-19 ST, 5) willingness to use COVID-19 ST again, and 6) ST for other diseases. This research shows the feasibility of a self-testing model in the community through workplaces due to participants' high acceptability to enrol and high self-tests' uptake. Lessons learnt can inform operational aspects of the introduction and scale-up of self-care strategies in low- and middle-income countries, in particular the South-East Asia region.
