The method has successfully been applied to regional resource utilisation problems [10].
In addition to its long tradition in process industry applications, PNS has also been successfully applied to regional resource utilisation problems [37].
In a final step, we aim to better understand the mechanisms with which math and science education contributes to the acquisition of problem-solving competence by exploring how math-science coherence, capability utilisation, and problem solving competence are related.
Further work on chronic illness and health service utilisation among problem drug users is advocated and this study offers a feasible study instrument.
Although multimorbidity has important implications for patient care in general practice, limited research has examined chronic illness and health service utilisation among problem drug users.
This study aimed to determine chronic illness prevalence and health service utilisation among problem drug users attending primary care for methadone treatment, to compare these rates with matched 'controls' and to develop and pilot test a valid study instrument.
In addition, with regard to the relative with dementia, two further secondary outcomes will be collected: the effects on health-care service utilisation and problem behaviour [ 19] (see Table 2).
The aims of this study were: - to determine chronic illness/multimorbidity prevalence and health service utilisation among problem drug users attending primary care for methadone treatment and to compare these rates with matched 'controls'; - to develop and pilot test a valid study instrument.
The results of our analyses suggest that an under-utilisation of problem solving capabilities in the acquisition of science literacy is linked to lower levels of math-science coherence, which ultimately leads to lower scores in problem solving competence.
Applying the above concepts from complexity theory to user fee exemption policies, it could be argued that these policies offer an apparently simple solution (of changing the financing structure for specific priority services, thereby reducing financial barriers to utilisation) to the problem of high maternal mortality, a complex problem.
