OBJECTIVE: This study assessed the availability, prices and affordability of medicines in public and private sectors in Malaysia to understand the pharmaceutical environment and guide policy recommendations.
METHODS: This nationwide cross-sectional study adapted the World Health Organization/Health Action International (WHO/HAI) methodology. A total of 87 premises from both public and private sectors participated in this study. Data on 50 medicines were collected to analyze availability, prices and affordability. Medicine prices were compared against the international reference prices (IRPs), and affordability was assessed by daily income level.
RESULTS: In the public sector, the average availability of generics (74.8%) was higher than that of the originator brand name products (19.4%). However, in the private sector, the availability of originator brands was higher (52.2%) than generics (49.1%). Procurement prices in the public sector were up to 1.5 times the IRPs, but up to 8.4 times in the private sector. The study also observed large price variation across medicines in the private sector. Median retail mark-ups in private hospitals (generics 166.9%; originators 51.0%) were higher than in retail pharmacies (generics 94.7%; originators 22.4%). Generics were generally affordable, but originator brands were unaffordable.
CONCLUSION: Current policies on generic medicines need to be strengthened to improve the availability and use of generics in the country. High medicine prices and large price variation in the current free market suggest that coherent pricing policies and regulations are needed to safeguard the accessibility and affordability of medicines for the people.
METHODS: This study was divided into three phases: (1) translation and linguistic validity involving both forward and backward translations; (2) establishment of face validity and content validity; and (3) establishment of reliability involving inter-rater, test-retest and internal consistency analyses. Data used for these analyses were obtained by interviewing 65 elderly respondents.
RESULTS: Percentages of Content Validity Index for 4 criteria were from 88.89 to 100.0. The Cronbach α coefficient for internal consistency was 0.838. Intra-class Correlation Coefficient of inter-rater reliability and test-retest reliability was 0.957 and 0.950 respectively.
CONCLUSIONS: The result shows that the Lawton Instrumental Activities of Daily Living Scale - Malay Version has excellent reliability and validity for use with the Malay speaking elderly people in Malaysia. This scale could be used by professionals to assess functional ability of elderly who live independently in community.
