Impact of an integrated medication management model on the collaborative working relationship among healthcare professionals in a hospital: an explanatory mixed methods study.

An integrated medication management (IMM) model was implemented in a medical center ward to improve the delivery of clinical pharmaceutical services (CPSs). This model incorporated a ward-based clinical pharmacist who performed medication reconciliation and medication reviews. It was perceived to promote interprofessional collaboration between pharmacists and non-pharmacist healthcare professionals (NPHPs, including attending physicians, nurse practitioners, and registered nurses). This study aimed to evaluate the effects of the IMM on NPHPs' intentions to collaborate with pharmacists and understand the mechanism of the impact of the IMM on interprofessional collaboration. A sequential explanatory mixed methods design was employed in the study. Initially, a questionnaire was administered to assess the effects of the IMM on NPHPs' intentions to collaborate with pharmacists. The NPHPs' experiences with the IMM were then documented using semi-structured interviews with inductive thematic analysis. Fifty-eight NPHPs completed the questionnaire, and NPHPs from the intervention ward reported a higher intention to discuss patient-related medication issues with pharmacists, indicating collaboration. Eleven NPHPs were interviewed, and they stated having better working relationships with pharmacists, experiencing more effective CPSs, and noting improved communication with pharmacists. The integration of quantitative and qualitative findings demonstrates that the critical mechanism of the IMM in promoting collaborative relationships is to integrate pharmacists into medical practice, which familiarizes NPHPs with pharmacists' roles, improves communication, and enables pharmacists to identify NPHPs' needs. To summarize, allowing ward-based pharmacists to engage in medical teams on a regular basis appears vital for improving interprofessional teamwork. Furthermore, stakeholders aiming to promote CPS in their institutions should consider the needs and communication channels among NPHPs.

A Qualitative Approach to Exploring Workflow and Cost Factors of Dispensing Services in Community Pharmacies in Taiwan.

Purpose: This study aimed to thoroughly document the process and cost factors involved in dispensing services within a community pharmacy. Methods: Using a cross-sectional design, this study incorporated a pragmatic and descriptive qualitative approach to outline pharmacists' viewpoints on providing dispensing services in community settings. A purposive sampling was employed to recruit pharmacists from geographically different community pharmacies, spanning from March to July 2022. Semi-structured interviews with direct content analysis were conducted through face-to-face interactions to gather firsthand insights into pharmacists' professional dispensing services. The data underwent analysis through descriptive and in vivo coding techniques to categorize, define, and label themes, thereby identifying key steps and cost components in the prescription dispensing process. The qualitative data management software, MAXQDA 2020, was utilized for data management and maintenance. Results: Ten community pharmacists participated in the study, cooperatively completing the interview process. Of these, 7 were male and 3 were female, with age ranging from 29 to 62 years. The average length of pharmacy practice experience was 11.4 years. The study revealed six integral steps in the dispensing process: (1) receiving and clarifying legality and completeness of prescriptions, (2) profiling and verifying patient prescriptions, (3) preparing prescription labels and containers, (4) dispensing right medications with right quantity, (5) inspecting dispensing accuracy, (6) handing over medications and providing counseling. Along with these processes, pharmacists emphasized that pharmacy manpower, representing a substantial portion of the associated costs, determines the success and quality of the dispensing service. Additionally, rental, utilities, consumables, and physical equipment were identified as other important cost factors associated with carrying out pharmacy dispensing services. Conclusion: The study offers a comprehensive understanding of the dispensing service workflow within community pharmacies. The findings may inform key stakeholders and policymakers about required resources for enhancing and sustaining quality dispensing services for the public in Taiwan.

Physiologically based mechanistic insight into differential risk of valproate hepatotoxicity between children and adults: A focus on ontogeny impact.

The anticonvulsant valproic acid (VPA) despite complex pharmacokinetics has been in clinical use for nearly 6 decades. Previous reports indicated neonates, infants, and toddlers/preschoolers had higher risk of valproate hepatotoxicity than adults. However, dosing recommendations for those less than 10 years of age are lacking. To decipher clinical puzzles, physiologically-based pharmacokinetic (PBPK) models of VPA and its hepatotoxic metabolite 4-ene-VPA were constructed and simulated with particularly integrated information of drug-metabolizing enzyme ontogeny. Adult and pediatric PK data of VPA (n = 143 subjects) and 4-ene-VPA (n = 8 subjects) collected from previous reports were used for model development and validation. Sensitivity analyses were performed to characterize ontogeny impacts of CYP2C9 and UGT2B7 on dispositions of VPA and 4-ene-VPA across age groups. Optimal VPA dosing for each pediatric age group was also predicted and objectively judged by ensuring VPA efficacy and avoiding 4-ene-VPA hepatotoxicity. The study revealed UGT2B7 ontogeny was quite influential on VPA clearance even in neonates and small children. Intrinsic clearance of CYP2C9 was the most prominent determinant for areas under the concentration-time curve of VPA and 4-ene-VPA in infants, and toddlers/preschoolers, reflecting higher hepatotoxicity risk due to noxious 4-ene-VPA accumulation in these groups. The ontogeny-based PBPK approach complements conventional allometric methods in dosing estimation for the young by providing more mechanistic insight of the processes changing with age. The established ontogeny-based PBPK approach for VPA therapy deserves further corroboration by real-world therapeutic data to affirm its clinical applicability.

Despite numerous attempts to mitigate their spread, misinformation and disinformation are rampant on social media and other public networks, posing a substantial risk to public health and individual well-being. A concerted, multi-channel approach is required to effectively tackle this evolving problem. This paper outlines potential strategies and actionable plans to improve the response to misinformation and disinformation by stakeholders from various healthcare ecosystems.

Mapping Real-World Data to Self-Reported Information to Explore Determinants of Location Selection for Community Pharmacies in Taiwan.

Background: Easy and adequate access to community pharmacies is key to eliminating primary barriers to the utilization of medicines and healthcare services. The location of community pharmacies is important for patients and providers when choosing and opening a pharmacy, but only a handful of studies investigate factors associated with the geographical distribution of pharmacies. This study aimed to identify decisive factors for location selection when starting a pharmacy among districts/townships in Taiwan. Methods: This cross-sectional mixed mode study employed an explanatory sequential design, beginning with a quantitative analysis of national datasets, and followed by a qualitative analysis of structured interviews. The national data were extracted from the Taiwan government database of 2020, and the qualitative interviews were conducted with 10 community pharmacists through a snowball sampling in 2021. A multiple linear regression was conducted to identify salient predictors of the number of community pharmacies in each of the 368 districts/townships in Taiwan, including population density, median annual household income, number of physician offices, area, and proportion of female residents of each district/township. Ten chief pharmacists were interviewed to share viewpoints on the decision-making process of their selection of current pharmacy practice sites. Inductive thematic analysis was performed to extract factors pertinent to location selection for pharmacy operations and services. Results: Confirmed by quantitative and qualitative data, population density, numbers of physician offices, median annual household income, pharmacy operation type, and type of retail locations are key determinants for site selection in considering opening a new community pharmacy. Conclusion: The study uncovers salient factors associated with the choice of community pharmacy location in Taiwan and proposes the adequate number of physician offices that a community pharmacy can collaborate with. In addition, pharmacists should prudently consider if their preferred service features match the needs of residents.

Impacts of medication non-adherence to major modifiable stroke-related diseases on stroke prevention and mortality: a meta-analysis.

BACKGROUND: Medication adherence is one of the crucial attempts in primary stroke prevention. The available evidence lacks comprehensive reviews exploring the association of medication adherence with stroke prevention. OBJECTIVES: To investigate the effects of non-adherence to medications used to treat the modifiable risk of diseases on stroke-associated outcomes in primary stroke prevention. METHODS: Study records were searched from PubMed, Embase, and CINAHL. Those studies reported risks relevant to stroke-associated outcomes and medication non-adherence for patients diagnosed with four modifiable stroke-related diseases (atrial fibrillation [AF], hyperlipidemia, hypertension, and type 2 diabetes mellitus) but without stroke history were included for meta-analysis and further subgroup, sensitivity, and publication bias analyses. A random effect model was performed to analyse the pooled risk estimates of relative risk (RR) and 95% confidence intervals (CIs). RESULTS: Thirty-nine studies (with 2,117,789 participants in total) designed as cohort or case-control studies were included. Those patients presenting with four stroke-related diseases and categorised as medication non-adherent tended to result in stroke and/or associated death (all pooled RR ≥ 1 and 95% CI did not include 1). The findings of stratification and sensitivity analysis for each stroke-related disease showed a similar trend. Non-adherent patients with AF were prone to stroke occurrence (RR 1.852; 95% CI 1.583-2.166) but inclined to reduced bleeding (RR 0.894; 95% CI 0.803-0.996). The existence of publication bias warrants further interpretation. CONCLUSIONS: Non-adherence to medications for the four stroke-related diseases contributes to the development of stroke and/or mortality in primary stroke prevention. More efforts are needed to improve patients' medication adherence.

Effects of a blended multimedia teaching approach on self-efficacy and skills in over-the-counter medication counselling versus a lecture-based approach: protocol for a prospective cohort study of undergraduate students from a pharmacy school in Taiwan.

INTRODUCTION: Addressing communication skills in pharmacy curricula is one of the effective tactics to equip future pharmacists with better skillsets for medication counselling. To achieve this, blended teaching of PowerPoint slides and videos holds great potential for undergraduate pharmacy education majors by integrating multimedia and performance feedback into instruction. This study will develop a blended teaching programme featuring didactic lectures with video-based materials to improve students' self-efficacy and skills in medication counselling. METHODS AND ANALYSIS: This study applies critical principles and effects outlined in multimedia learning by Richard Mayer et al to develop teaching materials and perform skill evaluation for two undergraduate cohorts (class of 2025 and 2026) enrolled in Introduction to Community Pharmacy separately in 2022 and 2023. Students will receive different teaching approaches to medication counselling. In the control cohort (ie, class of 2025), students will receive a 4-week PowerPoint slides-based instruction in communication skills. We will develop six videos illustrating common scenarios of over-the-counter (OTC) medication counselling in community pharmacies. In the intervention cohort (ie, class of 2026), students will receive a 3-week PowerPoint slides-based instruction and a week-long video-based instruction in communication skills. A pre-and-post survey will be administered to evaluate students' self-efficacy in OTC counselling. In addition, each student will be evaluated through one-on-one role-playing with standardised patients in the final to demonstrate their skills in OTC counselling. A structured checklist will be used to assess students' counselling skills. T-tests will be applied to examine differences in self-efficacy of OTC counselling. Multivariate regression analyses will determine which teaching approach better facilitates the development of self-efficacy and performance in OTC counselling. ETHICS AND DISSEMINATION: The Research Ethics Committee of the National Taiwan University Hospital approved this study. The findings will be shared with pharmacy educators and contribute to existing instructional methods to facilitate the competence of pharmacy students in OTC counselling.

Strengthening scientific credibility against misinformation and disinformation: Where do we stand now?

Health behaviors related to COVID-19 prevention measures, especially vaccination, are used to exemplify mechanisms whereby misinformation and disinformation can spark an "infodemic": a situation in which false information can spread more rapidly and widely than its truthful, science-based counterpart. We define key terminologies and identify potential sources that led to the pandemic infodemic, and highlight the harmful implications of such events. Issues related to scientific communication, how the public perceives information, and factors influencing individuals' decision-making are also discussed. This is the first in a series of two perspective articles on this topic.

Listening to White Noise Improved Verbal Working Memory in Children with Attention-Deficit/Hyperactivity Disorder: A Pilot Study.

Existing research demonstrates that children with attention-deficit/hyperactivity disorder (ADHD) underperform in cognitive tasks involving working memory (WM) due to hypo-arousal, which has led to the development of arousal regulation models to determine proper levels of arousal and optimal cognitive outcomes. The present study focuses on investigating the effects of external auditory stimuli on verbal WM in children with ADHD. Thirteen children with ADHD (aged 6-10 years old) and thirteen age- and gender-matched children with typical development (TD) completed the verbal WM task when listening to no sound, white noise, or pleasant music. A two-way repeated-measures analysis of variance was used to compare the verbal WM performance between groups in the three auditory conditions. Children with ADHD showed the best verbal WM performance when listening to white noise and the worst performance when listening to no sound. Yet, children with TD performed the best in the no-sound condition and the worst in the white noise condition. Our findings suggest auditory white noise is beneficial for ideal arousal regulation and cognitive performance involving verbal WM for children with ADHD and support the moderate brain arousal model. Providing external white noise is a non-invasive and cost-effective approach to improving verbal WM in children with ADHD in real-world contexts.

Feasibility of a Randomized Controlled Mixed Methods Trial to Address Health Literacy, Beliefs, Medication Adherence, and Self-Efficacy (ADHERE) in a Clinical Pharmacist-Led Clinic.

Purpose: To assess the feasibility and acceptability of a health literacy-psychosocial support intervention - ADHERE and explore changes in glycemic values and medication adherence. Patients and Methods: Thirty-one participants with hemoglobin A1c (HbA1c) ≥ 8% were randomly allocated to control (usual care) or intervention groups (receiving usual care plus a 6-session pharmacist-led intervention focusing on the modifiable psychosocial factors that may influence medication adherence). Feasibility metrics evaluated recruitment, retention, and intervention adherence. Questionnaires were administered to collect psychosocial factors and self-reported medication adherence at baseline, the end of the intervention, 3 months, and 6 months post intervention. HbA1c values were extracted from electronic medical records. Repeated measures analysis of variance was used to compare differences in mean outcomes between the control and intervention groups. To assess intervention acceptability, eleven individuals participated in semi-structured interviews about their intervention experiences. Qualitative content analysis was used for analyzing the interviews. Results: Thirty participants completed the study. Overall, the findings support the feasibility of the intervention. There were significant differences in HbA1c values. Participants in the intervention group had lower A1C (8.3 ± 1.4) than in the control group (9.2 ± 1.3) at the time of 6-month follow-up (p = 0.003). In addition, the participants in the intervention group showed improved HbA1c at 6-month follow-up (8.3 ± 1.4), compared to baseline (9.4 ± 1.5, p = 0.011) and after 6-session intervention (8.9 ± 1.6, p = 0.046). However, there were no significant differences in medication adherence between groups over time. Qualitative themes suggest participants liked the intervention and perceived the additional support from the pharmacist as beneficial. Conclusion: A pharmacist-led intervention to provide additional health literacy-psychosocial support may contribute to long-term improvements in HbA1c. Equipping pharmacists with patient-specific diabetes medication adherence information and building in additional follow-up support for patients may improve patient health outcomes.

Exploration of changes in pharmacy students' perceptions of and attitudes towards professionalism: outcome of a community pharmacy experiential learning programme in Taiwan.

BACKGROUND: A powerful way to nurture and strengthen professionalism is by accruing practice-based experiences. However, few studies in Taiwan have evaluated the impacts of experiential learning programmes on pharmacy students' views on professionalism - the core of quality healthcare practices and services. This study aimed to measure changes in perceptions of and attitudes towards professionalism among third-year pharmacy students following an introductory-intermediate experiential learning course. METHODS: A single-group pre- and postcourse comparative study using a self-administered survey was conducted in 2017. Pharmacy students in their third year of a six-year programme were eligible to participate in this study. We used a 28-item questionnaire with a 10-point Likert-type scale to assess students' professionalism. Among them, 10 items were employed to assess students' perceived importance of professionalism in pharmacy practice, and another 18 items adapted from the Pharmacy Professionalism Instrument were used to evaluate students' attitudes towards pharmacy professionalism. An independent t test was performed to compare the differences in students' anonymous survey responses before and after the course, with an a priori level of statistical significance of 0.05. RESULTS: Fifty-two pharmacy students participated in the study. They showed significant improvement in three tenets of professionalism, namely, altruism (p = 0.035), accountability (p = 0.026), and duty (p = 0.002), after completing the 5-week experiential course. CONCLUSIONS: Pharmacy students' attitudes towards professionalism were modifiable by purposely designed experiential learning programme in the community setting. Such experiences may help socialize students with positive attitudes towards altruism, accountability, and duty.

Lower caprylate and acetate levels in the breast milk is associated with atopic dermatitis in infancy.

BACKGROUND: Atopic dermatitis (AD) occurs in exclusively breastfed infants. As fatty acids have some immunomodulatory effect, we aimed to investigate the influence of fatty acid compositions in breast milk (BM) on the development of AD in exclusively breastfed infants. METHODS: We enrolled two- to four-month-old exclusively breastfed infants. The objective SCORing Atopic Dermatitis (objSCORAD) was evaluated. The lipid layer of BM was analyzed by gas chromatography for fatty acid levels. Medical charts were reviewed. RESULTS: Forty-seven AD infants and 47 healthy controls were enrolled. The objSCORAD was 20.5 ± 1.7 (shown as mean ± SEM) in the AD group. The age, sex, parental atopy history, and nutrient intake of mothers were not significantly different between two groups. The palmitate and monounsaturated fatty acid (MUFA) levels in BM positively correlated with objSCORAD, while caprylate, acetate, and short-chain fatty acid (SCFA) levels negatively correlated with objSCORAD (p = .031, .019, .039, .013, .022, respectively). However, the butyrate levels in BM were not significantly different. The caprylate and acetate levels in BM were significantly associated with the presence of infantile AD (p = .021 and .015, respectively) after adjusting for age, sex, parental allergy history, MUFA, palmitate, and SCFA levels in BM. ObjSCORAD in infancy was significantly associated with persistent AD (p = .026) after adjusting for age, sex, parental atopy history, caprylate, palmitate, MUFA, acetate, and SCFA levels in BM. CONCLUSION: Caprylate and acetate levels in BM for exclusively breastfed infants were negatively associated with objSCORAD. Lower caprylate and acetate in BM might be the risk factors for infantile AD, while butyrate in BM was not associated with infantile AD.

Engaging consumers in wise use of over-the-counter medications in Taiwan: Development and evaluation of a structured medication counseling approach.

OBJECTIVE: To evaluate the impact of a tailored Symptom Allergy Indication Direction Self-care (SAIDS) counseling by pharmacists on consumers' correct understanding of over-the-counter (OTC) medication use. METHODS: This study used a time-based sampling of two independent cohorts at a single community pharmacy in Taiwan for two years beginning in December 2018. In the control cohort, participants received conventional counseling for the OTCs they selected. In the intervention cohort, participants received SAIDS counseling along with pointing out OTC package label instructions. A paper-and-pencil survey was administered face-to-face to evaluate participants' understanding for the correct use of OTCs. Descriptive statistics and chi-square tests were used to evaluate the effect of the SAIDS approach on cohorts' understanding of OTC use. RESULTS: Compared with conventional OTC counseling, participants reported better understanding regarding potential side effects of OTCs that they acquired (p < 0.001) and were more aware of strategies to cope with the associated side effects (p < 0.001). CONCLUSIONS AND PRACTICE IMPLICATIONS: Despite the time constraints that pharmacists often can offer to each customer, the SAIDS counseling approach may refine the structure and effectiveness of pharmacists' OTC counseling skills and thereby improve consumers' understanding of their ailments and self-care medications in Taiwan.

Evaluation of use, comprehensibility and clarity of over-the-counter medicine labels: Consumers' perspectives and needs in Taiwan.

An estimate of one third of preventable medication errors occurred annually due to patients' misunderstanding of use instructions. To safeguard consumers' over-the-counter (OTC) medicine use and to develop future initiatives, this study evaluated the use, comprehensibility and clarity of the information labels on OTC packages from consumers' perspectives in Taiwan. This cross-sectional study was conducted at 29 community pharmacies; 50 pharmacy clerkship students helped participant enrolment from June to September 2017. Participants (n = 470) were 20 years old or above, Mandarin speaking, and with specific OTC purchases. A face-to-face survey was administered to investigate the degree to which participants read the package labels and their comprehension of correct medicine use. An 11-item survey was used to measure participants' specific OTC purchases (3 items), the use (2 items), comprehensibility (1 item) and clarity (2 items) of OTC package labels, in addition to the sociodemographic information (3 items). Participants were also solicited to provide opinions regarding package label redesign. Descriptive statistics and logistic regressions were applied for analyses. Findings show that most (84.0%) participants read instruction labels before use, with indications (79.4%), drug names (64.5%) and dosage and administration (59.8%) being the top reads. Only 30.0% of the participants fully understood how to take the medicines correctly. Younger (OR = 1.033, p < .001) and female participants (OR = 1.965, p = .014) with a higher level of education (OR = 1.940, p = .034) tended to read package label information prior to purchase or use. Younger participants (OR = 1.030, p < .001) and those who read OTC medicine labels before use (OR = 2.317, p = .004) were more likely to correctly understand medicine use. The findings indicate that older, male adults with a lower level of education should be targeted to ensure their correct understanding of OTC labels. Pharmacists should recite pertinent label information and, concomitantly, ensure consumers' understanding when providing medicine counselling.

Investigation of Barriers and Facilitators to Medication Adherence in Patients With Type 2 Diabetes Across Different Health Literacy Levels: An Explanatory Sequential Mixed Methods Study.

Type 2 diabetes (T2D) incurs tremendous healthcare costs associated with various complications due to poor blood sugar control. Medication adherence, which is correlated with patients' health literacy, should be consistently practiced to achieve optimal control of blood sugar. A comprehensive understanding of specific communication and psychosocial factors related to medication-taking behaviors across different levels of health literacy among people with T2D will guide the development of effective interventions and strategies to enhance medication adherence. To understand barriers and facilitators to medication adherence in people with T2D across different health literacy levels, the Health Literacy Pathway Model was used to identify the psychosocial and communication factors that may influence medication adherence. This mixed methods study used an explanatory sequential design, including a quantitative survey followed by qualitative semi-structured interviews. Two hundred and five participants completed the survey questionnaire, and 23 participants completed semi-structured interviews. Confirmed by quantitative and qualitative data, having stronger self-efficacy and fewer concerns about medications, as well as experiencing fewer perceived barriers to medication-taking, are necessary for better medication adherence among those with low adherence. Our findings will be useful to tailor interventions for diabetes care through addressing concerns among low-adherent patients with low health literacy and emphasizing self-efficacy and perceived barriers to medication adherence among all low-adherent patients with T2D.

Effects of a pharmacist-managed anticoagulation outpatient clinic in Taiwan: evaluation of patient knowledge, satisfaction, and clinical outcomes.

Objective: The study aimed to evaluate the improvement of patient knowledge of warfarin use, satisfaction with pharmacists, and the quality of international normalized ratio (INR) control after the implementation of an anticoagulant clinic (ACC) service.Methods: This was a prospective single-group pre- and post-comparison study. Patients who were at least 20 years of age and participated in a pharmacist-managed ACC service were enrolled from February 2012 to September 2015. Each participant completed a self-administered questionnaire before and after the ACC service to evaluate changes in warfarin knowledge. Another questionnaire was distributed after the ACC to evaluate participants' satisfaction with the pharmacist service in the ACC. The INR levels before and after the ACC intervention were obtained to calculate the proportion of time spent in the therapeutic INR range (time in therapeutic range, TTR). Paired t-tests were used to compare changes in participants' knowledge related to warfarin use. Multiple linear regressions were performed to explore the predictors associated with the participants' knowledge scores and TTR after the ACC intervention.Results: One hundred and forty-eight participants were enrolled in this study. A significant improvement (31.5%,p<0.001) in the knowledge of warfarin use was observed at the end of the ACC intervention. The interaction between warfarin and food was the most confusing factor for participants in warfarin use. More than 95% of the participants perceived a positive value of the pharmacist-managed ACC service. However, the consultation fee was the least satisfactory of the ACC service. The average TTR increased from 51.0±34.3% to 78.6±24.5% (p<0.001) after the ACC service was implemented. Participants' education levels and baseline knowledge scores were significant determinants associated with the knowledge improvement in the appropriate warfarin use (p<0.001).Conclusions: A pharmacist-managed ACC improved patient knowledge of warfarin use and INR control, and led to high satisfaction with the pharmacist service in the ACC in Taiwan. Pharmacists should focus on patients with lower education levels to facilitate their understanding of the appropriate warfarin use for better health outcomes.

Ideal instruments used to measure health literacy related to medication use: A systematic review.

BACKGROUND: Prior studies showed the association between inadequate health literacy (HL) and poor medication-related skills, while none of the published studies have reviewed and compared the existing instruments used to measure medication-related HL. This systematic review comprehensively summarizes the existing instruments that assess medication-related HL. OBJECTIVES: To identify appropriate HL instruments related to medication use as screening tools for enhancing patients' ability to use medications correctly. METHODS: This review retrieved medication-related HL instruments that were published between 2000 and 2019 from three databases (i.e., PubMed, Scopus, EMBASE) and by hand-searching. The PRISMA procedure was followed as well as the SURGE guideline to assess the quality of studies. Psychometric properties, HL dimensions, and types of medication information gleaned from the items in three types of HL instruments (i.e., general, disease-specific, medication-specific) were compared to identify appropriate medication-related HL instruments. RESULT: Forty-eight instruments were identified from 44 studies, whereas 70.8% instruments were either disease- or medication-specific HL instruments. Most instruments with different sample sizes showed certain an extent of reliability and validity. The distributions of HL dimensions and types of medication information among the relevant items were varied across different types of instruments. The five instruments (named as the 16SQ, AKQ-CQ, DHLKI, AKT, and ChMLM) were identified as the most appropriate instruments for three types of medication-related HL, respectively. These appropriate instruments consistently covered items related to HL dimensions of literacy and comprehension and medication-related information regarding dosing, treatment indication, and side effects/precautions. CONCLUSION: Of 48 identified instruments mainly derived from disease- or medication-specific studies, the five most appropriate medication-related HL instruments were identified to support clinicians in facilitating patients' correct medication use. Further confirmation to explore the usefulness among these instruments are needed.

Conceptualization, Development and Psychometric Evaluations of a New Medication-Related Health Literacy Instrument: The Chinese Medication Literacy Measurement.

There is a need for valid and reliable instruments to focus on medication aspects of health literacy and help healthcare professionals address patients' barriers to medication use. This cross-sectional study describes the conceptualization, development, and psychometric properties of the first Chinese Medication Literacy Measurement (ChMLM) to assess the level of health literacy on medication use. The 17-item ChMLM (ChMLM-17) and its short form, 13-item ChMLM (ChMLM-13), consist of four sections (vocabulary, over-the-counter labels, prescription labels, and advertisements) to cover six domains of medication-related health literacy. Multistage stratified quota sampling was attempted to recruit a representative sample in Taiwan. Receiver operating characteristic curves were used to identify the cut-off point for differentiating high and low medication literacy. Psychometric analyses were performed (n = 1410) to assess the reliability and validity separately on all samples and sociodemographic subgroups. The 17- and 13-item versions both had high construct validity among all patients and patients with low medication literacy. The developed ChMLM-17 and ChMLM-13 is expected to help healthcare providers and researchers to accurately measure medication-related health literacy and improve medication use in the real-world practice.
