METHODS: A computer-based SG (CBSG) tool was developed using Microsoft® PowerPoint 2007 to value asthma-specific health states in Malaysia. Eight hypothetical health states were considered, including two anchor states (healthy and dead), three chronic (C) states and three temporary (T) states (each numbered 1 through 3, with increasing severity) in addition to the subject's current health state. Twenty adult asthma patients completed the CBSG tool in addition to paper-based Asthma Control Test, three health status measures (EQ-5D, EQ-VAS, and Mini Asthma Quality of Life Questionnaire (MiniAQLQ)), and VAS utility assessment tool. Patients and interviewers rated the difficulty of the VAS and CBSG tools. Correlations between current health state values derived from the various measures were determined.
RESULTS: The SG and the VAS received similar difficulty ratings. 17 patients completed the CBSG tool within 30 minutes. The mean utilities determined by the CBSG tool for the T1-T3 asthma health states met the expected logical order of 1>2>3, but those for the C1-C3 states did not. Correlation between current health state values derived from the CBSG tool and other measurement tools was poor.
CONCLUSION: The CBSG tool developed for measuring utilities of asthma health states showed acceptable feasibility and overall validity.
METHODS: An activity-based microcosting approach was applied to estimate the unit cost of events from the hospital's perspective. First, activities and resources that were involved in each cost center were identified and valued against a suitable form of unit. Thereafter, the mean cost of each resource per event was calculated by dividing the product of the quantity of the resource used and the unit cost of the resource by the number of events. The mean cost per event was the sum of the cost of resources for all cost centers involved. The costs were expressed in 2014 US dollars ($) and Malaysian Ringgit (RM).
RESULTS: Data were collected from 15 maintenance, 20 acute exacerbation, and 50 hospitalization events. The mean (±SD) cost of maintenance management was $48.04 (±10.10); RM154.68 (±32.52). The cost of acute exacerbation management in the Emergency Department was $13.50 (±2.21), RM43.46 (±7.10); and in the medical ward, the cost was $552.13 (±303.41), RM1777.86 (±976.98), per hospitalization event.
CONCLUSION: The microcosting of management of asthma-related events provides more accurate estimates that could be used in local economic studies. However, its possible limited generalizability to other types of health care settings in Malaysia needs to be kept in mind.
METHODS: Online databases were searched for published journal articles in English language from year 1990 to 2012, using the search terms '"asthma" AND ("intervene" OR "manage") AND ("pharmacoeconomics" OR "economic evaluation" OR "cost effectiveness" OR "cost benefit" OR "cost utility")'. Hand search was done for local publishing. Only studies with full economic evaluation on enhanced management were included (cost consequences (CC), cost effectiveness (CE), cost benefit (CB), or cost utility (CU) analysis). Data were extracted and assessed for the quality of its economic evaluation design and evidence sources.
RESULTS: A total of 49 studies were included. There were 3 types of intervention for enhanced asthma management: education, environmental control, and self-management. The most cost-effective enhanced management was a mixture of education and self-management by an integrated team of healthcare and allied healthcare professionals. In general, the studies had a fair quality of economic evaluation with a mean QHES score of 73.7 (SD=9.7), and had good quality of evidence sources.
CONCLUSION: Despite the overall fair quality of economic evaluations but good quality of evidence sources for all data components, this review showed that the delivered enhanced asthma managements, whether as single or mixed modes, were overall effective and cost-reducing. Whilst the availability and accessibility are an equally important factor to consider, the sustainability of the cost-effective management has to be further investigated using a longer time horizon especially for chronic diseases such as asthma.
METHODS: We summarized the HTA process through review of documents and reports available in the public domain combined with the authors' experience.
RESULTS: Health technology assessment plays an integral part in prioritizing treatment in public health facilities in Malaysia, particularly for the Ministry of Health Medicines Formulary (MOHMF). The MOHMF is the reference list of drugs allowed to be prescribed in the Ministry of Health (MOH) facilities. There are 2 organizations within the MOH that conduct HTA as their core activities, namely the Malaysian Health Technology Assessment Section and the Formulary Management Branch of Pharmacy Practice & Development Division. The assessment of pharmaceuticals for the purpose of listing medicines into the MOHMF is under the purview of the Formulary Management Branch. The evidence-based assessment focuses on safety, efficacy, effectiveness, and budget impact of the drug. Cost-effectiveness evidence is currently not mandatory but is of interest to the decision makers. The assessment outcomes are considered by the MOH Medicines List Review Panel for formulary decisions.
CONCLUSIONS: Health technology assessment has supported formulary decisions in MOH. Evidence generation needs to progress beyond efficacy or effectiveness, safety, and budget impact to incorporate cost-effectiveness. Nevertheless, there are challenges to be met to achieve this. The impact of the HTA process is currently unknown and is yet to be evaluated formally.
