There are also ongoing efforts to introduce food safety regulations requiring nutrition labels on processed foods cheap 50 mg danazol overnight delivery. Of the few countries that have raised the price of unhealthy foods and drinks buy danazol 200mg fast delivery, none have measured the change in consumption levels to see if the policy is working or cost effective. There is little information available about reducing salt consumption, including in processed foods. Nor is there good information to promote the growing and marketing of more nutritious foods, including fruits and vegetables. Improving the efficiency and impact of the health budget Improving the efficiency and impact of the existing health budget by making better use of existing financial, human, and other resources in the health sector is a major strategic priority for countries. The starting point for responding to the growing challenges in the health sector is to make sure that ministries of health are making the best use of existing financial and human resources. There is a good deal of capacity to strengthen the planning, priority setting, resource allocation, and financial management of existing budgets in the Pacific Island countries. Such efforts would help free up existing resources that can be allocated to higher impact and more sustainable investments. Reallocating scarce resources to well-targeted primary and secondary preventions is particularly relevant to achieve improved health outcomes in a way that is affordable, cost- effective, and financially sustainable. Primary and secondary prevention strategies for diabetes and hypertension are particularly important policy priorities for most countries in the Pacific given the high health, financial, and economic burdens that those diseases impose on countries. Every person who adopted a healthy lifestyle and was able to avoid diabetes or keep it under control would avert direct drug costs to government of up to $367 per person per year. Effective and targeted secondary prevention is an especially strategic and potentially cost-effective intervention. That is because the pool of people at risk of progressing to insulin is limited, so targeting can be better focused. Figure 13 shows there is a similar step wise increase in the pharmaceutical costs of treating hypertension in Vanuatu. Effective and well-targeted primary and secondary prevention similarly yields health benefits for the individual and significant and sustained cost savings to government.

The average annual cost at each stage of treatment was based on the actual unit cost of the main drugs and the dosage used at the various stages in treating diabetes in Vanuatu.

The average annual cost at each stage of treatment was based on the actual unit cost of the main drugs and the dosage used at the various stages in treating hypertension in Vanuatu. But there is more to be done to improve the allocation and technical efficiency of public expenditure, and increase equitable outcomes. Recent analysis of the pharmaceutical diabetic costs in Vanuatu found that less than two percent of the population could be treated with insulin before the total government drug budget was exhausted. That analysis confirmed the overwhelming importance of allocating scarce resources to primary and secondary prevention efforts for high risk groups if treatment is to be financially sustainable for governments (Anderson et al. It is unclear whether Pacific Island governments are, in fact, focusing scarce resources on targeted prevention. Despite a lack of transparency and accountability in the use of public funds, it appears that the health outcomes for this older and privileged group were limited and modest at best, raising fundamental questions about the efficiency and equity gains in reallocating health resources. Strengthening the evidence base for improved investment Strengthening the evidence base is key to improving investment planning, program effectiveness, and ensuring value for money spent. French Polynesia, Cook Islands, Fiji, and Samoa are now in advanced planning or already undertaking surveys. Few, if any countries – or their development partners – are undertaking baseline studies prior to commencing interventions or seeking to measure the financial and broader resource cost (including human resources) of scaling up interventions, especially to more remote areas. Expanding the evidence base of “what works”, for whom, and at what cost, starting with a few key countries in the Pacific, would be a useful knowledge product and regional public good that policy makers throughout the Pacific could use to improve their resource allocation decision making. The Ministry of Agriculture could more actively promote the farming and marketing of fresh fruit, vegetables, and fish (perhaps by supporting investments in refrigeration at local markets) and restrict the use of land for small-scale tobacco leaf production. The Ministry of Communication could counter the aggressive marketing of unhealthy food and sugar-sweetened drinks, especially those deliberately targeted at children. The economic impacts, such as increased health expenditure, which is a greater proportion of income for the poor, job loss, and reduced productivity, tends to continue the poverty status (Murthy et al. Because high-fat, lower-fiber foods are usually cheaper than healthier alternatives, poorer people are generally more constrained to purchase low-cost food. Dietary choices, more sedentary lifestyles, and genetic factors have led to the obesity problem in the Pacific. As of 2015, just three of the 11 Pacific Possible nations do not meet this threshold. In addition, if diagnosed, poverty reduces the probability of complications being diagnosed early due to the inability to access, or lack of available quality healthcare. The greater diabetes prevalence in females is often due to the more sedentary lifestyle that women lead, causing obesity which is more prevalent among Pacific women than men (Ng et al. Unfortunately, diabetes is further known to precede the onset of heart disease and stroke (Hu, 2013).
