BackgroundThe unprecedented global increase in the use of herbal remedies is set to continue apace well into the foreseeable future. This raises important public health concerns, especially as it relates to safety issues including adverse effects and herb-drug interactions. Most Western-trained physicians are ignorant of the risks and benefits of this healthcare modality and assessment of acceptance and knowledge would identify appropriate intervention strategies to improve physician-patient communication in this area.MethodsA cross-sectional survey was done using an interviewer-administered pilot tested de novo questionnaire at six public hospitals in Trinidad between May–July 2004. The questionnaire utilized weighed questions to quantify acceptance (maximum score = 14 points) and knowledge (maximum score = 52 points). Acceptance and knowledge scores were analyzed using the ANOVA and Tukey's tests.ResultsOf 192 physicians interviewed, most (60.4%) believed that herbal remedies were beneficial to health. Respondents had relatively high acceptance levels (mean = 5.69 ± 0.29 points or 40% of total possible score) and poor knowledge (mean = 7.77 ± 0.56 points or 15% of total possible score). Seventy-eight physicians (40.6%) admitted having used herbs in the past, and 60 of these (76.9%) were satisfied with the outcome. Although 52 physicians (27.1%) recommended the use of herbs to their patients only 29 (15.1%) were able to identify at least one known herb-drug interaction.ConclusionThe use of herbal remedies is relatively high in Trinidad, as throughout the world, and most patients self-medicate with or without the knowledge of their attending physician. Surprisingly, we demonstrated relatively high acceptance levels and use of herbs among physicians in Trinidad. This interesting scenario of high acceptance levels and poor knowledge creates a situation that demands urgent intervention. We recommend educational intervention to narrow the gap between acceptance and knowledge so that physicians would be adequately equipped to communicate with their patients on this modality. The integration of herbal medicine into the curriculum of medical schools, continuing education programs and the availability of reputable pharmacopoeias for referencing at public health institutions are useful instruments that can be used to close this gap and promote improved physician-patient communication.

Background. Proper handwashing can reduce the burden of diseases related to hand hygiene (HH) and so contribute reducing under-5 mortality. Preschoolers can benefit from HH interventions by the burden of disease and absenteeism being reduced. Objective. To perform a scoping review of literature to assess the types and effectiveness of HH interventions at preschools, with a view to providing a guideline for appropriate interventions for South African facilities. Methods. A literature search was conducted through the PubMed database to identify relevant studies. An iterative screening process to focus the review allowed for information on the type and effectiveness of interventions to be collated. An updated PubMed search was conducted to determine whether any interventions related to COVID-19 at preschools could be included. Results. No additional studies relating to COVID-19 were found. Of the 305 studies identified during the initial search, only 12 fitted the specific search criteria. Of these, 10 studies showed improvements in HH-related indicators following the interventions. Only two studies used health education as an intervention, whereas the others included the supply of HH products (to varying extents) as part of the intervention. Conclusion. HH interventions appear successful in reducing diseases spread by poor HH, improving general HH practices and reducing absenteeism among preschoolers. Studies using innovative, entertaining methods of educating children have shown to be successful in improving handwashing techniques and decreasing microbial growth on children’s hands. HH interventions are suggested as an effective measure to improve HH during the COVID-19 pandemic
