Cost-utility analysis of an alcohol policy in Thailand: a case study of a random breath testing intervention.

BACKGROUND: Road traffic injuries are a major concern worldwide, with Thailand facing high accident mortality rates. Drunk driving is a key factor that requires countermeasures. Random breath testing (RBT) and mass media campaigns recommended by the World Health Organisation intend to deter such behaviour. This study aimed to evaluate the cost-effectiveness of implementing RBT in combination with mass media campaigns in Thailand. METHODS: A Markov simulation model estimated the lifetime cost and health benefits of RBT with mass media campaigns compared to mass media campaigns only. Direct medical and non-medical care costs were evaluated from a societal perspective. The health outcomes were quality-adjusted life years (QALY). Costs and outcomes were discounted by 3% per year. Subgroup analyses were conducted for both sexes, different age groups, and different drinking levels. Probabilistic sensitivity analyses were conducted over 5,000 independent iterations using a predetermined distribution for each parameter. RESULTS: This study suggested that RBT with mass media campaigns compared with mass media campaigns increases the lifetime cost by 24,486 THB per male binge drinker and 10,475 THB per female binge drinker (1 USD = 35 THB) and results in a QALY gain of 0.43 years per male binge drinker and 0.10 years per female binge drinker. The intervention yielded incremental cost-effectiveness ratios (ICERs) of 57,391 and 103,850 THB per QALY for male and female drinkers, respectively. Moreover, the intervention was cost-effective for all age groups and drinking levels. The intervention yielded the lowest ICER among male-dependent drinkers. Sensitivity analyses showed that at a willingness-to-pay (WTP) threshold of 160,000 per QALY gained, the RBT combined with mass media campaigns had a 99% probability of being optimal for male drinkers, whereas the probability for females was 91%. CONCLUSIONS: RBT and mass media campaigns in Thailand are cost-effective for all ages and drinking levels in both sexes. The intervention yielded the lowest ICER among male-dependent drinkers. Given the current Thai WTP threshold, sensitivity analyses showed that the intervention was more cost-effective for males than females.

Selecting topic areas for developing quality standards in a resource-limited setting.

Variation in practices of and access to health promotion and disease prevention (P&P) across geographical areas have been studied in Thailand as well as other healthcare settings. The implementation of quality standards (QS)-a concise set of evidence-informed quality statements designed to drive and measure priority quality improvements-can be an option to solve the problem. This paper aims to provide an overview of the priority setting process of topic areas for developing QS and describes the criteria used. Topic selection consisted of an iterative process involving several steps and relevant stakeholders. Review of existing documents on the principles and criteria used for prioritising health technology assessment topics were performed. Problems with healthcare services were reviewed, and stakeholder consultation meetings were conducted to discuss current problems and comment on the proposed prioritisation criteria. Topics were then prioritised based on both empirical evidence derived from literature review and stakeholders' experiences through a deliberative process. Preterm birth, pre-eclampsia and postpartum haemorrhage were selected. The three health problems had significant disease burden; were prevalent among pregnant women in Thailand; led to high mortality and morbidity in mothers and children and caused variation in the practices and service uptake at health facilities. Having agreed-on criteria is one of the important elements of the priority setting process. The criteria should be discussed and refined with various stakeholders. Moreover, key stakeholders, especially the implementers of QS initiative, should be engaged in a constructive way and should be encouraged to actively participate and contribute significantly in the process.

Perceived barriers to utilise methadone maintenance therapy among male injection drug users in rural areas of southern Thailand.

INTRODUCTION AND AIMS: Methadone maintenance therapy (MMT) has been proven to be effective and cost-effective in treating dependence on opioids. However, concerns remain that geographical, financial and other hidden barriers may hinder access to MMT, especially in rural areas where health services are limited. The objective of this study was to determine factors associated with utilisation of MMT by injection drug users (IDUs) living in Songkhla province. DESIGN AND METHODS: A cross-sectional study among 159 IDUs in Songkhla province of southern Thailand was conducted. Participants were recruited using a snowball technique. Data were collected from July 2013 to January 2014 via face-to-face interviews. RESULTS: Around one-forth (24.5%) of participants had difficulties travelling to MMT clinics because of the long distance, long travelling time and lack of a private vehicle. Twenty-four percent faced difficulties with the clinic's opening hours and 28% faced difficulties paying for the cost of travel. IDUs who utilised the MMT perceived risks of injection drug use differently compared with those who did not. Younger or Muslim IDUs were less likely to attend MMT. IDUs who perceived that MMT was effective were more likely to utilise MMT. DISCUSSION AND CONCLUSIONS: Physical accessibility, affordability and acceptability play an essential role in MMT utilisation. Developing alternatives that reduce the travelling time, costs for IDUs and more convenient operation hours to suit their lifestyles may increase the utilisation of MMT. Intensive consultation before starting MMT is highly recommended.
