Malaria rapid diagnostic tests (RDTs) may assist in diagnosis, improve prescribing practices and reduce potential drug resistance development. Without understanding operational issues or acceptance and usage by providers and patients, the costs of these tests may not be justified.
To evaluate the impact of RDTs on prescribing behaviours, assess prescribers' and patients' perceptions, and identify operational issues during implementation.
Baseline data were collected at six Tanzanian public dispensaries. RDTs were implemented for eight weeks and data collected on frequency of RDT use, results, malaria diagnoses and the prescription of antimalarials. Patients referred for RDTs completed a standardised exit interview. Qualitative methods assessed attitudes toward and satisfaction with RDTs, perceptions about the test and operational issues related to implementation.
Of 595 patients at baseline, 200 (33%) were diagnosed clinically with malaria but had a negative RDT. Among the 2519 RDTs performed during implementation, 289 (11.5%) had a negative result and antimalarials prescribed. The proportion of "over-prescriptions" at baseline was 54.8% (198/365). At weeks four and eight this decreased to 16.1% (27/168) and 16.4% (42/256) respectively.A total of 355 patient or parent/caregiver and 21 prescriber individual interviews and 12 focus group discussions (FGDs) were conducted. Patients, caregivers and providers trusted RDT results, agreed that use of RDTs was feasible at dispensary level, and perceived that RDTs improved clinical diagnosis. Negative concerns included community suspicion and fear that RDTs were HIV tests, the need for additional supervision in interpreting the results, and increased work loads without added compensation.
Overprescriptions decreased over the study period. There was a high degree of patient/caregiver and provider acceptance of and satisfaction with RDTs. Implementation should include community education, sufficient levels of training and supervision and consideration of the need for additional staff.
疟疾快速诊断检测(RDTs)有助于诊断,改善处方行为并减少潜在的耐药性发展。如果不了解这些检测的操作问题以及提供者和患者的接受程度与使用情况,那么这些检测的成本可能就不合理。
评估RDTs对处方行为的影响,评估开处方者和患者的看法,并确定实施过程中的操作问题。
在坦桑尼亚的六个公共药房收集基线数据。实施RDTs八周,并收集关于RDTs使用频率、结果、疟疾诊断和抗疟药处方的数据。接受RDTs检测的患者完成标准化的出院访谈。定性方法评估了对RDTs的态度和满意度、对检测的看法以及与实施相关的操作问题。
在基线时的595名患者中,有200名(33%)临床诊断为疟疾,但RDT检测结果为阴性。在实施期间进行的2519次RDT检测中,有289次(11.5%)结果为阴性但仍开出了抗疟药。基线时“过度处方”的比例为54.8%(198/365)。在第四周和第八周,这一比例分别降至16.1%(27/168)和16.4%(42/256)。总共进行了355次患者或家长/照顾者以及21次开处方者的个人访谈和12次焦点小组讨论(FGDs)。患者、照顾者和提供者信任RDT检测结果,一致认为在药房层面使用RDTs是可行的,并认为RDTs改善了临床诊断。负面问题包括社区怀疑并担心RDTs是艾滋病毒检测,在解读结果时需要额外的监督,以及工作量增加但没有额外补偿。
在研究期间过度处方减少。患者/照顾者和提供者对RDTs的接受程度和满意度很高。实施应包括社区教育、足够水平的培训和监督以及考虑对额外工作人员的需求。
