Determining compliance with the COVID-19 daily symptom monitoring tool used to identify suspected COVID-19 workers of the military health support formation employees of the South African national defence force

Introduction: the COVID-19 pandemic had prompted governments in many countries to enact laws and policies to combat the spread of COVID-19 at work. The DEL required every worker to be screened when they arrived at work. Screening methods included self-reporting symptoms using a symptom monitoring tool. This study aimed to determine compliance with the symptom monitoring tool by assessing the knowledge, attitude, and practice of the MHSF employees. Methods: a cross-sectional questionnaire was administered to the employees. Information related to demographic, COVID-19 exposure, knowledge of COVID-19 and the symptom monitoring tool, attitude towards the symptom monitoring tool and practices towards COVID-19 and the symptom monitoring tool was collected. Results: a total of 90 participants participated in the study. The majority (N=45; 50%) of respondents were aged between 30 and 39 years old, with more female (N=50) than male (N=40) participants. The majority (N=51; 56.7%) only had grade 12 as the highest level of education. There were 25% (N=10) of males and 20% (N=10) of females who contracted COVID-19. The relationship between the COVID-19 positive cases and the symptom monitoring tool identifying symptoms had a strong negative correlation (-0.932). Respondent's knowledge of COVID-19 and the symptom monitoring tool was moderate (72.4%), with the attitude to the symptom monitoring tool being moderate (63.3%) as well. However, the practices of the COVID-19 guidelines and the symptom monitoring tool were good (93.3%).

HIV oral self-screening test among HIV/STD/TB clinic attendees: A mixed-method pilot investigation examining merit for largerevaluation

Background & objectives: Globally, several countries consider HIV self-test as an important element in the toolbox to end AIDS by 2030. Against this background, the present investigation was conducted to pilot test the performance of an indigenous HIV oral self-test (HIVOST) and explore its acceptability. The overall purpose was to examine if this kit could serve as a promising tool and merit future larger clinical evaluation. Methods: A concurrent mixed-method investigation was undertaken during March-October 2019. One hundred and thirty two consecutive HIV/sexually transmitted diseases/tuberculosis clinic attendees were invited for participation; of whom, 100 were enrolled, and among them, 40 provided consent for qualitative in-depth interviews. The HIVOST kit assessed for its performance served as the ‘index test’, which worked on the principle of lateral flow chromatography. The results of the HIVOST were interpreted independently by the study physicians and participants at 20 min. HIVOST kit performance was assessed against the HIV confirmatory blood test result based on the national algorithm (3 rapid test or 1 ELISA and 2 rapid test) serving as the ‘reference’. Sensitivity, specificity, positive predictive value, negative predictive value and inter-rater agreement were estimated. The voices and concerns of the study participants were coded followed by identification of qualitative themes and ideas. Results: The sensitivity and specificity of the index test at the end of 20 min as interpreted by the participants were 83.3 per cent [95% confidence interval (CI): 69.8 to 92.5] and 98 per cent (95% CI: 89.4 to 99.5), respectively. Study physicians and participants independently interpreted HIVOST results with substantial inter-rater agreement (kappa value 0.88; 95% CI: 0.78-0.97). All HIVOST test strips were valid. Majority of the participants preferred saliva over blood for HIV self-test. ‘Comfort’, ‘confidentiality’ and ‘convenience’ were the perceived advantages of HIVOST. Some of the participants wished the package inserts contained ‘how-to-do instructions in local languages’, ‘expiry date (if any)’ and ‘contact helpline number’. A few of them highlighted the need for a confirmatory HIV result following oral self-test. Concerns of the participants revolved around potential self-harm following HIVOST-positive result and safe disposal of kits.Interpretation & conclusions: Two major highlights of the present investigation are (i) high level of concordance in HIVOST results interpreted by participants and physicians, and (ii) encouraging level of acceptance of HIVOST. These findings and encouraging HIVOST performance statistics lend support towards large-scale clinical evaluation of this index test.

Validity and Reliability of Falls Screening Mobile Application (FallSA) to Inform Falls Risk among Malaysian Community Dwelling Older Adults / Jurnal Sains Kesihatan Malaysia

@#Falls is a global health concern due to its many negative consequences in older adults. Early falls screening and prevention is important among older adults. We developed Falls Screening Mobile Application (FallSA) as a self falls screening tool among older adults. FallSA was developed using data of physical performance test, demographic information and questions to inform falls risk from a larger population based longitudinal study on neuroprotective model for healthy longevity among older adults (LRGS TUA). The aim of this study was to determine validity and reliability of FallSA as a self-screening tool to inform falls risk among Malaysian older adults. This cross sectional study was conducted among 91 community dwelling older adults aged 60 years and above. FallSA was validated against Physiological Profile Assessments (PPA), a comprehensive falls risk assessment tool. Participants used FallSA to test their falls risk by repeating the test twice between an hour. Validity and test–retest reliability of FallSA was examined by using Spearman correlation, Kappa, Sensitivity and Specificity, Intra correlation coefficient (ICC), Cronbach alpha and Bland-Altman respectively. Concurrent validity test was significant with moderate correlation rs = 0.518, p < 0.001, moderate agreement K = 0.516, p < 0.001 and acceptable Sensitivity: 80.4% and Specificity: 71.1%. Reliability of FallSA was shown to be good (ICC: 0.948, CI: 0.921-0.966), good internal consistency α = 0.948, p < 0.001 and good agreement indicate by small mean differences and narrow limits of agreement (LoA). The results of this study suggest that FallSA was a valid and reliable tool to inform falls risk among Malaysian older adults. Further prospective studies are required to determine the accuracy of FallSA to correctly classify older adults into fallers and non-faller groups.
