This paper examines the impact of the scale-up of malaria rapid diagnostic tests (RDT) on routine clinical diagnosis procedures for febrile illness in primary healthcare settings in Papua New Guinea.
Repeat, cross-sectional surveys in randomly selected primary healthcare services were conducted. Surveys included passive observation of consecutive febrile case management cases and were completed immediately prior to RDT scale-up (2011) and at 12- (2012) and 60-months (2016) post scale-up. The frequency with which specified diagnostic questions and procedures were observed to occur, with corresponding 95% CIs, was calculated for febrile patients prescribed anti-malarials pre- and post-RDT scale-up and between febrile patients who tested either negative or positive for malaria infection by RDT (post scale-up only).
A total of 1809 observations from 120 health facilities were completed across the three survey periods of which 915 (51%) were prescribed an anti-malarial. The mean number of diagnostic questions and procedures asked or performed, leading to anti-malarial prescription, remained consistent pre- and post-RDT scale-up (range 7.4-7.7). However, alterations in diagnostic content were evident with the RDT replacing body temperature as the primary diagnostic procedure performed (observed in 5.3 and 84.4% of cases, respectively, in 2011 vs. 77.9 and 58.2% of cases in 2016). Verbal questioning, especially experience of fever, cough and duration of symptoms, remained the most common feature of a diagnostic examination leading to anti-malarial prescription irrespective of RDT use (observed in 96.1, 86.8 and 84.8% of cases, respectively, in 2011 vs. 97.5, 76.6 and 85.7% of cases in 2016). Diagnostic content did not vary substantially by RDT result.
Rapid diagnostic tests scale-up has led to a reduction in body temperature measurement. Investigations are very limited when malaria infection is ruled out as a cause of febrile illness by RDT.
本文研究了在巴布亚新几内亚基层医疗保健环境中,疟疾快速诊断检测(RDT)的推广对发热病例常规临床诊断程序的影响。
在随机选择的基层医疗服务中进行重复的横断面调查。调查包括对连续发热病例管理病例进行被动观察,并在 RDT 推广之前(2011 年)和推广后 12 个月(2012 年)和 60 个月(2016 年)立即完成。计算了在 RDT 推广之前和之后,为发热患者开具抗疟药物的情况下,观察到指定诊断问题和程序的频率,并计算了相应的 95%置信区间,以及 RDT 检测为疟疾感染阴性或阳性的发热患者之间的频率(仅在推广后)。
在三个调查期间共完成了 1809 次观察,其中 120 个卫生设施中有 915 次(51%)被开具了抗疟药物。在 RDT 推广之前和之后,询问或执行的诊断问题和程序的平均数量保持一致(范围为 7.4-7.7)。然而,随着 RDT 取代体温成为主要的诊断程序,诊断内容发生了变化(2011 年分别观察到 5.3%和 84.4%的病例,而 2016 年分别观察到 77.9%和 58.2%的病例)。口头询问,尤其是发热、咳嗽和症状持续时间的经历,仍然是导致开具抗疟药物的最常见的诊断检查特征,无论是否使用 RDT(2011 年分别观察到 96.1%、86.8%和 84.8%的病例,而 2016 年分别观察到 97.5%、76.6%和 85.7%的病例)。诊断内容在 RDT 结果方面没有显著差异。
RDT 的推广导致体温测量减少。当 RDT 排除疟疾感染是发热原因时,调查非常有限。
