In Uganda, as in most other malaria-endemic countries, presumptive treatment for malaria based on symptoms without a diagnostic blood test is still very common. While diagnostic testing in public sector facilities is increasing, many people in Uganda who suspect malaria visit private sector outlets to purchase medications. Increasing the availability and uptake of rapid diagnostic tests (RDTs) for malaria in private outlets could help increase diagnostic testing for malaria but raises questions about the patient demand for and valuation of testing that are less critical for public sector introduction.
In preparation for a behaviour change campaign to encourage and sustain the demand for RDTs in drug shops, eight focus group discussions with a total of 84 community members were conducted in six districts across Uganda's Eastern Region in November-December 2011. Focus groups explored incentives and barriers to seeking diagnosis for malaria, how people react to test results and why, and what can be done to increase the willingness to pay for RDTs.
Overall, participants were very familiar with malaria diagnostic testing and understood its importance, yet when faced with limited financial resources, patients preferred to spend their money on medication and sought testing only when presumptive treatment proved ineffective. While side effects did seem to be a concern, participants did not mention other potential costs of taking unnecessary or ineffective medications, such as money wasted on excess drugs or delays in resolution of symptoms. Very few individuals were familiar with RDTs.
In order to boost demand, these results suggest that private sector RDTs will have to be made convenient and affordable and that targeted behaviour change campaigns should strive to increase the perceived value of diagnosis.
与大多数其他疟疾流行国家一样,在乌干达,基于症状而非诊断性血液检测的疟疾推定治疗仍然非常普遍。虽然公共部门设施中的诊断检测正在增加,但乌干达许多怀疑感染疟疾的人会前往私营部门购买药物。增加私营部门快速诊断检测(RDT)的可及性和使用率有助于提高疟疾诊断检测,但也引发了关于患者对检测的需求和重视程度的问题,而这些问题对于公共部门引入检测来说并不那么关键。
为筹备一项行为改变运动以鼓励并维持药店对RDT的需求,2011年11月至12月在乌干达东部地区的六个区与总共84名社区成员进行了八次焦点小组讨论。焦点小组探讨了寻求疟疾诊断的激励因素和障碍、人们对检测结果的反应及原因,以及如何提高为RDT付费的意愿。
总体而言,参与者对疟疾诊断检测非常熟悉并理解其重要性,但在面临资金有限时,患者更愿意把钱花在药物上,只有在推定治疗无效时才寻求检测。虽然副作用似乎确实是一个问题,但参与者没有提及服用不必要或无效药物的其他潜在成本,比如浪费在多余药物上的钱或症状缓解延迟。很少有人熟悉RDT。
为了增加需求,这些结果表明,必须使私营部门的RDT方便且价格合理,有针对性的行为改变运动应努力提高诊断的感知价值。
