The Process of Listing Prostheses and Medical Devices in Thailand's Universal Health Coverage.

OBJECTIVES: This study aimed to characterize the processes of listing prostheses and medical devices in all insurance schemes. METHODS: A literature review was performed, and in-depth interviews were conducted with the representatives of 6 insurance agencies. Civil Servant Medical Benefits Scheme (CSMBS), Social Security Scheme, Local Government Officer Scheme (LGOS), State Enterprise Scheme (SES), Universal Coverage Scheme (UCS), and Non-Thai Resident Scheme (NTRS). RESULTS: The outcomes of interest were structure details and the body of the working groups, listing processes, and key assessment criteria. Each insurance scheme's process can be summarized in 5 steps: (1) receiving the proposed topics of health technologies, (2) screening, (3) selection, (4) consideration, and (5) approval and publicization. Notably, the organizational structures and working group compositions vary across schemes, leading to differences in process activities and assessment criteria. LGOS and SES are exceptions because they follow the application process of CSMBS. UCS demonstrates the most transparent process, providing specific working groups that are competent in undertaking each activity. The processes of listing prostheses and medical devices vary across health insurance in Thailand, leading to varying numbers of health technologies covered by insurance schemes. CONCLUSIONS: This study characterizes prostheses and medical device listing processes in 6 Thai Universal Health Coverage insurance schemes (CSMBS, Social Security Scheme, UCS, LGOS, SES, and Non-Thai Resident Scheme). Variations in processes result in differing technology listings. It offers essential insights for healthcare professionals and policy makers.

The impact of home-based management of malaria on clinical outcomes in sub-Saharan African populations: a systematic review and meta-analysis.

BACKGROUND: Malaria remains a significant cause of morbidity and mortality globally and continues to disproportionately afflict the African population. We aimed to evaluate the effect of home management of malaria intervention on health outcomes. METHODS: In our systematic review and meta-analysis, six databases (Pubmed, Cochrane CENTRAL, EMBASE, CAB Abstracts and Global Health, CINAHL Complete, and BIOSIS) were searched for studies of home management of malaria from inception until November 15, 2023. We included before-after studies, observational studies, and randomised controlled trials of home management intervention delivered in community settings. The primary outcomes were malaria mortality and all-cause mortality. The risk of bias in individual observational studies was assessed using the ROBINS-I tool, whilst randomised controlled trials were judged using a revised Cochrane risk of bias tool and cluster-randomised controlled trials were evaluated using an adapted Cochrane risk of bias tool for cluster-randomised trials. We computed risk ratios with accompanying 95% confidence intervals for health-related outcomes reported in the studies and subsequently pooled the results by using a random-effects model (DerSimonian-Laird method). RESULTS: We identified 1203 citations through database and hand searches, from which 56 articles from 47 studies encompassing 234,002 participants were included in the systematic review. All studies were conducted in people living in sub-Saharan Africa and were rated to have a low or moderate risk of bias. Pooled analyses showed that mortality rates due to malaria (RR = 0.40, 95% CI = 0.29-0.54, P = 0.00001, I2 = 0%) and all-cause mortality rates (RR = 0.62, 95% CI = 0.53-0.72, P = 0.00001, I2 = 0%) were significantly lower among participants receiving home management intervention compared to the control group. However, in children under 5 years of age, there was no significant difference in mortality rates before and after implementation of home management of malaria. In terms of secondary outcomes, home management of malaria was associated with a reduction in the risk of febrile episodes (RR = 1.27, 95% CI = 1.09-1.47, P = 0.002, I2 = 97%) and higher effective rates of antimalarial treatments (RR = 2.72, 95% CI = 1.90-3.88, P < 0.00001, I2 = 96%) compared to standard care. Home malaria management combined with intermittent preventive treatment showed a significantly lower incidence risk of malaria than home management intervention that exclusively provided treatment to individuals with febrile illness suggestive of malaria. The risks for adverse events were found to be similar for home management intervention using different antimalarial drugs. Cost-effectiveness findings depicted that home malaria management merited special preferential scale-up. CONCLUSIONS: Home management of malaria intervention was associated with significant reductions in malaria mortality and all-cause mortality. The intervention could help decrease health and economic burden attributable to malaria. Further clinical studies are warranted to enable more meaningful interpretations with regard to wide-scale implementation of the intervention, settings of differing transmission intensity, and new antimalarial drugs.

Genetic polymorphisms influencing deferasirox pharmacokinetics, efficacy, and adverse drug reactions: a systematic review and meta-analysis.

Objective: Deferasirox is an iron-chelating agent prescribed to patients with iron overload. Due to the interindividual variability of deferasirox responses reported in various populations, this study aims to determine the genetic polymorphisms that influence drug responses. Methods: A systematic search was performed from inception to March 2022 on electronic databases. All studies investigating genetic associations of deferasirox in humans were included, and the outcomes of interest included pharmacokinetics, efficacy, and adverse drug reactions. Fixed- and random-effects model meta-analyses using the ratio of means (ROM) were performed. Results: Seven studies involving 367 participants were included in a meta-analysis. The results showed that subjects carrying the A allele (AG/AA) of ABCC2 rs2273697 had a 1.23-fold increase in deferasirox Cmax (ROM = 1.23; 95% confidence interval [CI]:1.06-1.43; p = 0.007) and a lower Vd (ROM = 0.48; 95% CI: 0.36-0.63; p < 0.00001), compared to those with GG. A significant attenuated area under the curve of deferasirox was observed in the subjects with UGT1A3 rs3806596 AG/GG by 1.28-fold (ROM = 0.78; 95% CI: 0.60-0.99; p = 0.04). In addition, two SNPs of CYP24A1 were also associated with the decreased Ctrough: rs2248359 CC (ROM = 0.50; 95% CI: 0.29-0.87; p = 0.01) and rs2585428 GG (ROM = 0.47; 95% CI: 0.35-0.63; p < 0.00001). Only rs2248359 CC was associated with decreased Cmin (ROM = 0.26; 95% CI: 0.08-0.93; p = 0.04), while rs2585428 GG was associated with a shorter half-life (ROM = 0.44; 95% CI: 0.23-0.83; p = 0.01). Conclusion: This research summarizes the current evidence supporting the influence of variations in genes involved with drug transporters, drug-metabolizing enzymes, and vitamin D metabolism on deferasirox responses.

Association Between Cytomegalovirus Infection and Tuberculosis Disease: A Systematic Review and Meta-Analysis of Epidemiological Studies.

BACKGROUND: Tuberculosis is one of the leading causes of mortality worldwide from an infectious disease. This review aimed to investigate the association between prior cytomegalovirus infection and tuberculosis disease. METHODS: Six bibliographic databases were searched from their respective inception to 31 December 2021. Data were pooled using random-effects meta-analysis. RESULTS: Of 5476 identified articles, 15 satisfied the inclusion criteria with a total sample size of 38 618 patients. Pooled findings showed that individuals with cytomegalovirus infection had a higher risk of tuberculosis disease compared to those not infected with cytomegalovirus (odds ratio [OR], 3.20; 95% confidence interval [CI], 2.18-4.70). Age was the only covariate that exerted a significant effect on the result of the association. Meta-analysis of risk estimates reported in individual studies showed a marked and significant correlation of cytomegalovirus infection with active tuberculosis (adjusted hazard ratio, 2.92; 95% CI, 1.34-4.51; adjusted OR, 1.14; 95% CI, .71-1.57). A clear dose-response relation was inferred between the levels of cytomegalovirus antibodies and the risks of tuberculosis events (OR for high levels of cytomegalovirus antibodies, 4.07; OR for medium levels of cytomegalovirus antibodies, 3.58). CONCLUSIONS: The results suggest an elevated risk of tuberculosis disease among individuals with a prior cytomegalovirus infection.

A systematic review on pharmacists' turnover and turnover intention.

BACKGROUND: Turnover is an important issue in all healthcare professions including pharmacy practice settings. A high turnover rate of pharmacists, not only has negative financial impact, but also reduces quality of care and patient safety. The high turnover also increases workload and job stress which can increase job errors and decrease job efficiency and performance in pharmacy practices. OBJECTIVES: To systematically review the extent of pharmacists' turnover and their intention to leave their jobs or the pharmacy profession. METHODS: An electronic search was performed from database inception to December 19, 2020 using the following 6 databases; PubMed, Scopus, ScienceDirect, ProQuest, ERIC, and ERIC-EBSCO. Articles were included if they were relevant to reports of pharmacist turnover or turnover intention. Only research studies were included, but not editorials, letters, or review articles. RESULTS: Twenty-eight studies were contained within this systematic review. Using the QualSyst assessment tool to assess the included article qualities, all studies demonstrated good quality with quality assessment score of 0.75. Fifteen studies (53.6%) were conducted from the US, 3 studies (10.7%) from Taiwan, 2 studies (7.1%) from the UK, and the remaining studies from Lithuania, Australia, New Zealand, Malaysia, Saudi Arabia, and Jamaica. The turnover of the pharmacists from their jobs ranged from 8.6 to 17%, and the turnover from the pharmacy profession was in the range of 6-9%. The turnover intention of the pharmacists in their jobs was from 13% to 61.2%, and the turnover intention in the pharmacy profession was 6.5%-18.8%. Hospital pharmacists had significantly higher turnover intentions than community ones. The turnover intention rates of both hospital and community pharmacists have gradually increased over time in both European countries and Asian countries. CONCLUSION: Based on the included articles, pharmacists' turnover rate appeared to increase over time. However, based on the heterogeneity of studies, further research is warranted to confirm this and to help to identify the potential causes of turnover intention since intention was related to behavior.

Association between adherence and severe asthma exacerbation: A systematic review and meta-analysis.

OBJECTIVE: To assess the association between adherence levels and severe asthma exacerbation. DESIGN: A systematic search was performed from inception to November 2018 on the following databases: PubMed, CENTRAL, EMBASE, and ClinicalTrials.gov. SETTING AND PARTICIPANTS: Randomized-controlled trials (RCTs) and cohort and case-control studies that investigated the impact of adherence to controller medications on severe asthma exacerbation were included in the analysis. Data extraction was undertaken by 2 reviewers, and all studies were assessed for their qualities using the Cochrane risk of bias tool for RCT and the Newcastle-Ottawa scale for cohort and case-control studies. Random-effects model meta-analyses were performed. OUTCOME MEASURES: Severe asthma exacerbation. RESULTS: From 8061 articles, 8 studies were included in quantitative synthesis. The meta-analyses revealed that the odds of exacerbation among the patients with 80% or more adherence were lowered by 47% (odds ratio 0.53 [95% CI 0.42-0.66], P < 0.001) compared with less than 80%. When compared with less than 20% adherence, a 33% reduction in the odds (0.67 [0.53-0.86], P = 0.001) was associated with the patients achieving 50% or more, whereas a decrease in exacerbation was not associated with 20% to 49% adherence (0.94 [0.85-1.04], P = 0.22). In addition, a 2.4-fold increase in the odds (2.4 [2.1-2.7], P < 0.001) was associated with discontinuation of therapy. CONCLUSION: The highest reduction in the odds of exacerbation was associated with patients achieving 80% or more adherence, and the odds also reduced among those with 50% or more adherence, whereas a substantial increase in exacerbation was associated with discontinuation of therapy.

Incorporating adherence in cost-effectiveness analyses of asthma: a systematic review.

Aims: Non-adherence is associated with poor clinical outcomes among patients with asthma. While cost-effectiveness analysis (CEA) is increasingly used to inform value assessment of the interventions, most do not take into account adherence in the analyses. This study aims to: (1) Understand the extent of studies considering adherence as part of the economic analyses, and (2) summarize the methods of incorporating adherence in the economic models. Materials and methods: A literature search was performed from the inception to February 2018 using four databases: PubMed, EMBASE, NHS EED, and the Tufts CEA registry. Decision model-based CEA of asthma were identified. Outcomes of interest were the number of studies incorporating adherence in the economic models, and the incorporating methods. All data were extracted using a standardized data collection form. Results: From 1,587 articles, 23 studies were decision model-based CEA of asthma, of which four CEA (17.4%) incorporated adherence in the analyses. Only the method of incorporating adherence by adjusting treatment effectiveness according to adherence levels was demonstrated in this review. Two approaches were used to derive the associations between adherence and effectiveness. The first approach was to apply a mathematical formula, developed by an expert panel, and the second was to extrapolate the associations from previous published studies. The adherence-adjusted effectiveness was then incorporated in the economic models. Conclusions: A very low number of CEA of asthma incorporated adherence in the analyses. All the CEA adjusted treatment effectiveness according to adherence levels, applied to the economic models.

Weight Reduction and Pioglitazone are Cost-Effective for the Treatment of Non-Alcoholic Fatty Liver Disease in Thailand.

INTRODUCTION: This study evaluated lifetime liver-related clinical outcomes, costs of treatment, and the cost-effectiveness of treatment options for non-alcoholic fatty liver disease (NAFLD) in Thailand. METHODS: A cost-utility analysis using a lifetime Markov model was conducted among Thai patients with NAFLD, from a societal perspective. Pioglitazone, vitamin E, a weight reduction program, and usual care were investigated, with the outcomes of interest being the number of cirrhosis and hepatocellular carcinoma (HCC) cases, life expectancy, quality-adjusted life-years (QALYs), lifetime costs, and the incremental cost-effectiveness ratios (ICERs). One-way and probabilistic sensitivity analyses were performed. RESULTS: When compared with usual care, a weight reduction program can prevent cirrhosis and HCC cases by 13.91% (95% credible interval [CrI] 0.97, 20.59) and 2.12% (95% CrI 0.43, 4.56), respectively; pioglitazone can prevent cirrhosis and HCC cases by 9.30% (95% CrI -2.52, 15.24) and 1.42% (95% CrI -0.18, 3.74), respectively; and vitamin E can prevent cirrhosis and HCC cases by 7.32% (95% CrI -4.64, 15.56) and 1.12% (95% CrI -0.81, 3.44), respectively. Estimated incremental life expectancy and incremental QALYs for all treatment options compared with usual care were approximately 0.06 years and 0.07 QALYs, respectively. The lifetime costs of both a weight reduction program and pioglitazone were less than usual care, while vitamin E was $3050 (95% CrI 2354, 3650). The weight reduction program dominated all other treatment options. The probability of being cost-effective in Thailand's willingness-to-pay threshold ($4546/QALY gained) was 76% for the weight reduction program, 22% for pioglitazone, 2% for usual care, and 0% for vitamin E. CONCLUSIONS: A weight reduction program can prevent cirrhosis and HCC occurrences, and dominates all other treatment options. Pioglitazone and vitamin E demonstrated a trend towards decreasing the number of cirrhosis and HCC cases.

The Effects of Telemedicine on Asthma Control and Patients' Quality of Life in Adults: A Systematic Review and Meta-analysis.

BACKGROUND: Telemedicine is increasingly used to improve health outcomes in asthma. However, it is still inconclusive which telemedicine works effectively. OBJECTIVE: This study aimed to determine the effects of telemedicine on asthma control and the quality of life in adults. METHODS: An electronic search was performed from the inception to March 2018 on the following databases: Cochrane CENTRAL, CINAHL, ClinicalTrials.gov, EMBASE, PubMed, and Scopus. Randomized controlled trials that assessed the effects of telemedicine in adults with asthma were included in this analysis, and the outcomes of interest were levels of asthma control and quality of life. Random-effects model meta-analyses were performed. RESULTS: A total of 22 studies (10,281 participants) were included. Each of 11 studies investigated the effects of single-telemedicine and combined-telemedicine (combinations of telemedicine approaches), and the meta-analyses showed that combined tele-case management could significantly improve asthma control compared with usual care (standardized mean difference [SMD] = 0.78; 95% confidence interval [CI]: 0.56, 1.01). Combined tele-case management and tele-consultation (SMD = 0.52 [95% CI: 0.13, 0.91]) and combined tele-consultation (SMD = 0.28 [95% CI: 0.13, 0.44]) also significantly improved asthma outcomes, but to a lesser degree. In addition, combined tele-case management (SMD = 0.59 [95% CI: 0.31, 0.88]) was the most effective telemedicine for improving quality of life, followed by combined tele-case management and tele-consultation (SMD = 0.31 [95% CI: 0.03, 0.59]), tele-case management (SMD = 0.30 [95% CI: 0.05, 0.55]), and combined tele-consultation (SMD = 0.27 [95% CI: 0.11, 0.43]), respectively. CONCLUSIONS: Combined-telemedicine involving tele-case management or tele-consultation appear to be effective telemedicine interventions to improve asthma control and quality of life in adults. Our findings are expected to provide health care professionals with current evidence of the effects of telemedicine on asthma control and patients' quality of life.

Clinical effects of Zingiber cassumunar (Plai): A systematic review.

Zingiber cassumunar Roxb. known locally as "Plai" in Thai, has been used for treating bruise, sprain and musculoskeletal pain. Several pre-clinical studies demonstrated the anti-inflammatory effect of Plai. However, current evidence of clinical effects of Plai is still unclear. This study aimed to determine the clinical efficacy and safety of Plai among all identified indications. Of the 808 articles identified by a systematic review, six studies were included. Four studies were randomized controlled trials, while two studies were quasi-experimental studies involving 178 patients in intervention group and 177 patients in control group. Duration of treatment ranged from 7days to 2 months. Our findings showed that 14% Plai cream had a strong trend of benefits in pain reduction for muscle pain and ankle sprain. However, evidence supporting the effects of Plai on acne vulgaris treatment and anti-histamine effect are still unclear.

Economic evaluations of Haemophilus influenzae type b (Hib) vaccine: a systematic review.

AIMS: The World Health Organization (WHO) recommends the use of Haemophilus influenzae type b (Hib) conjugate vaccines, but China and Thailand have not used Hib vaccination in their national immunization programs. This systematic review aimed to update published economic evaluations of Hib vaccinations and to determine factors that potentially affected their cost-effectiveness. METHODS: Searches were performed from the inception until December 2015 using 13 databases: CAB direct; CEA registry; EconLit; EMBASE; E-library; NHSEED; PAHO; POPLINE; PubMed; Redalyc project; RePEc; SciELO; and WHOLIS. Reference lists of relevant studies and grey literature were also searched. Full economic evaluations of Hib vaccination with results of costs and outcomes were included. The WHO checklist was used to evaluate the quality of the included studies. Data from eligible studies were extracted using a standardized data collection form. RESULTS: Out of 830 articles, 27 were included. Almost half of the studies (12/27) were conducted in high-income countries. Twelve studies (12/27) investigated the Hib vaccine as an addition to the existing vaccination program. Most studies (17/27) examined a 3-dose schedule of Hib vaccine. Nineteen studies (19/27) reported the model used, where all were decision tree models. Most of the studies (23/27) demonstrated an economic value of Hib vaccination programs, key influential parameters being incidence rates of Hib disease and vaccine price. CONCLUSIONS: Hib vaccination programs are mostly found to be cost-effective across geographic regions and country income levels, and Hib vaccination is recommended for inclusion into all national immunization programs. The findings are expected to support policy-makers for making decisions on allocating limited resources of the Hib vaccination program effectively.

A cost-utility analysis of dabigatran, enoxaparin, and usual care for venous thromboprophylaxis after hip or knee replacement surgery in Thailand.

To analyze the cost-utility of oral dabigatran etexilate, enoxaparin sodium injection, and no intervention for venous thromboembolism (VTE) prophylaxis after total hip or knee replacement (THR/TKR) surgery among Thai patients. A cost-utility analysis using a decision tree model was conducted using societal and healthcare payers' perspectives to simulate relevant costs and health outcomes covering a 3-month time horizon. Costs were adjusted to year 2014. The willingness-to-pay threshold of THB 160,000 (USD 4926) was used. One-way sensitivity and probabilistic sensitivity analyses using a Monte Carlo simulation were performed. Compared with no VTE prophylaxis, dabigatran and enoxaparin after THR and TKR surgery incurred higher costs and increased quality adjusted life years (QALYs). However, their incremental cost-effectiveness ratios were high above the willingness to pay. Compared with enoxaparin, dabigatran for THR/TKR lowered VTE complications but increased bleeding cases; dabigatran was cost-saving by reducing the costs [by THB 3809.96 (USD 117.30) for THR] and producing more QALYs gained (by 0.00013 for THR). Dabigatran (vs. enoxaparin) had a 98 % likelihood of being cost effective. Dabigatran is cost-saving compared to enoxaparin for VTE prophylaxis after THR or TKR under the Thai context. However, both medications are not cost-effective compared to no thromboprophylaxis.

Comparative efficacy of interventions on nonalcoholic fatty liver disease (NAFLD): A PRISMA-compliant systematic review and network meta-analysis.

BACKGROUND: The prevalence of nonalcoholic fatty liver disease (NAFLD) has significantly increased over the last decades. Despite existence of several interventions, there remains unclear which interventions work the best. METHODS: A systematic review and network meta-analysis of randomized trials comparing efficacy of all treatment options in NAFLD were performed to determine comparative efficacy and safety of interventions in the management of NAFLD. Several electronic databases were searched up to Nov 15, 2015. Outcomes include liver histological outcomes (i.e., fibrosis), all-cause mortality, cirrhosis, and safety. A network meta-analysis was applied to estimate pooled risk ratios (RR). Quality of evidence was assessed using GRADE criteria. RESULTS: A total of 44 studies (n = 3802) were eligible. When compared with placebo, obeticholic acid (OCA) was the only intervention that significantly improved fibrosis with RR (95% CI) of 1.91 (1.15, 3.16), while pentoxyfylline (PTX) demonstrated improved fibrosis without statistical significance with RR (95% CI) of 2.27 (0.81, 6.36). Only thiazolidinedione (TZD) and vitamin E use resulted in significant increase in resolution of NASH, while OCA, TZD, and vitamin E significantly improved other outcomes including NAS, steatosis, ballooning, and inflammation outcomes. Quality of evidence varied from very low (i.e., metformin, PTX on mean change of ballooning grade) to high (OCA, TZD, vitamin E on improving histological outcomes). Limitations of this study were lack of relevant long-term outcomes (e.g., cirrhosis, death, safety), possible small study effect, and few head-to-head studies. CONCLUSIONS: Our study suggests potential efficacy of OCA, TZD, and vitamin E in improving histologic endpoints in NAFLD. These findings are however based on a small number of studies. Additional studies are awaited to strengthen this network meta-analysis.
