Exploring the Use of Traditional Medicines, Natural Health Products and Conventional Medicines: Development and Testing of the New Zealand 'All-Medicines' Questionnaire.

INTRODUCTION: Traditional, complementary and alternative medicine (TCAM) are popular healthcare choices among consumers globally. The latest national data on the use of TCAM practitioners in New Zealand (NZ) were collected over a decade ago. Robust data on the use of natural health products (NHPs) and TCAM practices alongside conventional medicines are not yet available in NZ. OBJECTIVES: This study aimed to develop and test a bespoke questionnaire (All-MedsNZ) that included comprehensive data collection elements exploring NHPs' and conventional medicines' use. METHODS: This was a questionnaire design study involving expert panel feedback, and engagement with TCAM users, in the development process. This work comprised questionnaire development (stage 1) followed by a questionnaire-testing study (stage 2). The questionnaire was developed on the basis of literature review findings and the research team's expertise. The questionnaire content was then validated by an expert panel comprising practitioners in TCAM and conventional medicine. Then, a two-phase study was utilised to test the questionnaire. Phase 1 involved participants (NHP users) completing the web-based questionnaire and providing feedback by answering probing questions added throughout the questionnaire to evaluate users' comprehension of the questions and to identify issues with the questionnaire. In phase 2, selected participants were interviewed online to gain in-depth insights into issues identified in phase one. Based on these findings, the questionnaire was revised. RESULTS: The expert panel (n = 9) confirmed the questionnaire had high face and content validity; most original questions were retained. In the questionnaire-testing study, 95 and 27 participants completed the phase 1 and 2 studies, respectively. Most questions achieved a high response rate of ≥ 90%, and participants had no major issues understanding and answering the questionnaire. Problematic questions were those relating to providing product barcodes and photographs, and information on product costs. Most of the NHPs data entered by participants included the brand/generic name, manufacturer/company name, main ingredient(s) and dose form. Generally, these NHP-related data were of acceptable quality. However, information on the main ingredient(s) of products entered by participants was less satisfactory: approximately one-third of the 143 NHPs recorded in the study had the main ingredient(s) missing or incorrectly stated. Interviews with participants reiterated the issues identified in the phase 1 study. The low response rates for some of the questions were partly due to participants' unpreparedness (i.e. not having NHPs/medicines on hand) to complete the questionnaire. In addition, a lack of clarity for the term 'natural health practitioner' led to confusion among some participants. CONCLUSION: Overall, no major design-, method- or questionnaire-related issues were identified in this development and testing work. The questionnaire demonstrated adequate face and content validity and acceptability among participants. The data collected were reasonably complete and of sufficient quality for analysis. Future studies should pilot the revised All-MedsNZ questionnaire with a larger, nationally representative sample to ascertain its feasibility and utility.

Prevalence of Use of Traditional, Complementary and Alternative Medicine by the General Population: A Systematic Review of National Studies Published from 2010 to 2019.

INTRODUCTION: Traditional, complementary and alternative medicine (TCAM) refers to a broad range of health practices and products typically not part of the 'conventional medicine' system, and its use is substantial among the general population. TCAM products and therapies may be used in addition to, or instead of, conventional medicine approaches, and some have been associated with adverse reactions or other harms. OBJECTIVES: The aims of this systematic review were to identify and examine recently published national studies globally on the prevalence of TCAM use in the general population, to review the research methods used in these studies and to propose best practices for future studies exploring prevalence of use of TCAM. METHODS: MEDLINE, Embase, CINAHL, PsycINFO and AMED were searched to identify relevant studies published since 2010. Articles/reports describing the prevalence of TCAM use in a national study among the general population were included. The quality of included studies was assessed using a risk of bias tool developed by Hoy et al. Relevant data were extracted and summarised. RESULTS: Forty studies from 14 countries, comprising 21 national surveys and one cross-national survey, were included. Studies explored the use of TCAM products (e.g. herbal medicines), TCAM practitioners/therapies, or both. Included studies used different TCAM definitions, prevalence time frames and data collection tools, methods and analyses, thereby limiting comparability across studies. The reported prevalence of use of TCAM (products and/or practitioners/therapies) over the previous 12 months was 24-71.3%. CONCLUSION: The reported prevalence of use of TCAM (products and/or practitioners/therapies) is high, but may underestimate use. Published prevalence data varied considerably, at least in part because studies utilise different data collection tools, methods and operational definitions, limiting cross-study comparisons and study reproducibility. For best practice, comprehensive, detailed data on TCAM exposures are needed, and studies should report an operational definition (including the context of TCAM use, products/practices/therapies included and excluded), publish survey questions and describe the data-coding criteria and analysis approach used.

Traditional, complementary and alternative medicine (TCAM) includes products (e.g. herbal medicines, dietary supplements) and therapies/practices (e.g. chiropractic, acupuncture), and is a popular healthcare choice for many people. This study systematically reviewed national surveys of TCAM use around the world. We identified studies carried out in 14 different countries and one continent (Europe) on the extent of use of TCAM in the general population. TCAM use was found to be substantial, ranging from 24 to 71.3% in different countries. National surveys use different methods and different survey questionnaires. Some studies did not publish the survey questionnaire that they used and/or did not describe the types of TCAM included in the study. This means that it is not possible to compare the results between countries or to do further data analysis. For example, the survey questions from different countries asked people if they had 'used' or 'seen a practitioner' for a specific therapy, such as homeopathy. These questions look similar, but could elicit different answers from people. This means that the answers to these questions cannot be pooled together or compared directly. Also, some studies collected information on use of a category of TCAM products, such as herbal medicines, but other studies collected information on use of specific herbal medicines, such as St John's wort. New surveys of the extent of use of TCAM should provide full information on the types of TCAM products, practices and therapies included in the study and consider collecting comprehensive information on use of specific TCAM products, practices and therapies.

Mapping prevalence and patterns of use of, and expenditure on, traditional, complementary and alternative medicine in New Zealand: a scoping review of qualitative and quantitative studies.

AIM: Traditional, complementary and alternative medicine (TCAM) is a popular healthcare choice worldwide. The extent of data available on TCAM, including prevalence and patterns of use in New Zealand, is unknown. This scoping review aims to map the existing research describing the use of TCAM (including prevalence, access, expenditure and concurrent use with conventional medicines) in New Zealand. METHOD: Research databases (MEDLINE, EMBASE, AMED, IPA (International Pharmaceutical Abstracts), CINAHL, PsycINFO and Scopus) and grey literature (Google Scholar and New Zealand government and relevant organisations' websites) were searched for studies published before 7 June 2019. Studies reporting on the prevalence and/or exploring aspects of TCAM use were included in this review. RESULTS: In total, 72 studies were reviewed. Available data suggest that TCAM use is widespread among New Zealanders, and some consumers pay large sums of money out-of-pocket. A wide range of TCAM practices and products is used by people of all ages and ethnicities and with various health conditions. There is some evidence of consumers using TCAM concurrently with conventional medicines. Studies were generally small, localised and conducted in sub-populations (e.g., specific age groups, health conditions). Different TCAM definitions, data collection tools, methods and prevalence measurement were used across studies, thereby limiting the comparability of data locally and internationally. CONCLUSION: A considerable number of studies/reports on TCAM use are available. Still, there is a lack of comprehensive, nationally representative data on prevalence and patterns of use of TCAM, including its use in relation to conventional medicine(s) in New Zealand.

What role could community pharmacists in Malaysia play in diabetes self-management education and support? The views of individuals with type 2 diabetes.

OBJECTIVES: This study explored the experiences and views of individuals with type 2 diabetes mellitus (T2D) on their diabetes self-management and potential roles for community pharmacists in diabetes self-management education and support (DSME/S) in Malaysia. METHODS: A qualitative study, using semi-structured, face-to-face interviews, was conducted with patients with T2D attending a primary care health clinic in Kuala Lumpur, Malaysia. The interviews were audio-recorded, transcribed verbatim and analysed inductively. KEY FINDINGS: Fourteen participants with T2D were interviewed. Data were coded into five main themes: experience and perception of diabetes self-management, constraints of the current healthcare system, perception of the community pharmacist and community pharmacies, perceived roles for community pharmacists in diabetes care, and challenges in utilising community pharmacies to provide DSME/S. There were misconceptions about diabetes management that may be attributed to a lack of knowledge. Although participants described potential roles for community pharmacists in education, medication review and continuity of care, these roles were mostly non-clinically oriented. Participants were not confident about community pharmacists making recommendations and changes to the prescribed treatment regimens. While participants recognised the advantages of convenience of a community pharmacy-based diabetes care service, they raised concerns over the retail nature and the community pharmacy environment for providing such services. CONCLUSION: This study highlighted the need to improve the care provision for people with T2D. Participants with T2D identified potential, but limited roles for community pharmacists in diabetes care. Participants expressed concerns that need to be addressed if effective diabetes care is to be provided from community pharmacies in Malaysia.
