This study investigates how prioritisation in health services have influenced speech and language therapy (SLT) services in Scotland in prioritising their caseload. Additionally, it evaluates how current prioritisation systems may contribute towards the development of the SLT service in Malaysia. Health, education and social agencies in Malaysia were contacted and a literature review was conducted. Information on prioritisation systems used in Malaysia was unavailable. Prioritisation systems from seven SLT departments within Scotland were investigated, of which three SLT managers took part in semi-structured interviews. The findings show that prioritisation is influenced by a combination of factors and that the principles could only be applied to the Malaysian SLT service if consideration is given to the political, economical, social, geographical and cultural factors.
