OBJECTIVES: The study aims to develop and validate scales (direct and indirect) based on a modified Theory of Planned Behavior (TPB) to measure factors associated with the provision of PCare for HDS users by Thai CPs.
METHOD: Item generation for the scales was based on the theoretical constructs of the modified TPB framework, literature review, and authors' previous qualitative study. Draft items were then subjected to content validity and face validity. Psychometric testing was carried out among CPs in Bangkok, Thailand. Refinement of the scales utilized factor analysis and validity was assessed using factor analysis and Rasch analysis. Internal consistency reliability and construct reliability were used to assess the scales' reliability.
RESULTS: Initially, the direct and indirect scales contained 15 and 28 items, respectively and were reduced to 12 and 16 items, after experts' review. Factor analysis further reduced the number of items of the indirect scale to 13. For both scales, confirmatory factor analysis showed model-data fit. Each construct of the direct scale was significant predictors of intention. Moreover, each construct of the direct scale correlated positively and significantly with the respective construct of the indirect scale, signifying concurrent validity. No misfit item was identified in the Rasch analysis and the majority of items were invariant across gender. Internal consistency reliability and construct reliability of the scales were acceptable.
CONCLUSION: This study presents the development and validation of theoretically-grounded scales to measure the factors associated with the provision of PCare for HDS users by Thai CPs.
OBJECTIVE: This scoping review aimed to identify and describe existing studies on pretravel health services provided by CPs, and the barriers, and facilitators.
METHODS: The PubMed, Science Direct, Scopus, and Web of Science databases were searched for pertinent studies from their inception to February 2023. A manual search was also conducted of prominent travel medicine journals, Google Scholar, and the reference lists of the included studies. Potential barriers and facilitators were mapped to the 14 domains of the Theoretical Domains Framework (TDF).
RESULTS: There were twelve studies included in the review. Pretravel health advice was the most prevalent form of pretravel health services. Within ten domains of the TDF, various factors that either facilitate or impede the provision of pretravel health services by CPs were identified.
CONCLUSION: The provision of pretravel health services by CPs may be affected by a number of practitioner and organizational factors. The provision of pretravel health services can be facilitated by informational resources, training and education in travel medicine, and collaboration amongst healthcare providers.
METHODS: An online cross-sectional survey was conducted between May and June 2021 involving adults ≥ 18 years old. Data on the self-reported use of HDS for COVID-19 prevention were collected. Logistic regression analysis was conducted to determine the predictors of HDS use.
RESULTS: Overall, 41.9 % (168/401) reported using HDS to prevent COVID-19. Multivariate analysis showed that HDS users were more likely to be individuals ≥ 40 years old (adjusted odds ratio [aOR] = 1.774, 95 % confidence interval [CI] = 1.016 - 3.098), and to have had a history of HDS use prior to the pandemic (aOR = 19.378, 95 % CI = 5.901 - 63.639). Most HDS users referred to social media or websites (66.7 %, 112/168) for HDS information. Approximately half of them had consulted either pharmacists or doctors about their HDS use.
CONCLUSION: HDS use to prevent COVID-19 was common among the respondents. Several issues - such as the concurrent use of HDS with conventional medications, the use of unreliable sources of information, and the lack of consultation with healthcare providers (HCPs) - indicate that HCPs should be more proactive in their consultative and information-providing roles regarding HDS use.
METHODS: A cross-sectional survey was conducted between March and May 2019 among the elderly aged ≥60 years old. The participants with the following criteria were included in the study: aged ≥60 years, residing in Puncak Alam and able to understand Malay or English language. Data were collected using a pre-validated questionnaire. All statistical analysis was conducted using IBM SPSS ver. 23.
RESULTS: Overall, 336 out of 400 elderly responded to the survey, achieving a response rate of 84%. This study observed that almost 50% of the respondents were using at least one type of HDS in the past one month of the survey. Among HDS non-users, most of them preferred to use modern medicines (62.6%, 114/182). Among the HDS users, 75.3% (116/154) were using at least one type of modern medicine (prescription or over-the-counter medicine). Multivariate analysis showed that having good to excellent perceived health (adjusted OR = 2.666, 95% CI = 1.592-4.464), having felt sick at least once in the past one month (adjusted OR = 2.500, 95% CI = 1.426-4.383), and lower body mass index (adjusted OR = 0.937, 95% CI = 0.887-0.990) were associated with HDS use. It was noted that only a small percentage of HDS users (16.2%, 25/154) had informed healthcare providers on their HDS use.
CONCLUSION: The use of HDS is common among the elderly sampled. Hence, healthcare providers should be more vigilant in seeking information of HDS use for disease management in their elderly patients. Campaigns that provide accurate information regarding the appropriate use of HDS among the elderly are pertinent to prevent misinformation of the products.
METHODOLOGY: A cross-sectional study to evaluate the quality and risks of websites discussing TA supplements was conducted. Online marketing websites, research articles, news articles, personal opinions, and those restricted by password were excluded. The quality and risks of websites were assessed using a modified DISCERN tool and a set of risk assessment criteria, respectively. The health claims for TA were identified and analyzed using content analysis.
RESULTS: Overall, 321 websites met the inclusion criteria and were further evaluated. The overall rating of the quality of the websites was low, with a mean score ± standard deviation of 1.07 ± 0.51. Most websites lacked information that there may be more than one possible treatment choice and did not discuss areas of uncertainty. However, 67.9% (218/321) of the websites received a risk score of zero. A minority of websites (5/321, 1.6%) discouraged the use of conventional medicines. The most common health claims for TA included in the websites related to the enhancement of testosterone level (121/321, 37.7%), treatment of malaria (112/321, 34.9%), and improvement in libido (108/321, 33.6%).
CONCLUSIONS: Websites containing information about TA supplements generally have a low-quality rating based on a modified DISCERN tool despite having a low-risk score. Government agencies and healthcare professionals (HCPs) must be more proactive in the critique and dissemination of information relating to HM, and in ensuring the safe use of HM among the public and patients.
