This study aimed to explore how clinical uncertainty influences antibiotic prescribing practices among township hospital physicians and village doctors in rural Shandong Province, China.
Qualitative semi-structured interviews were conducted with 30 township hospital physicians and 6 village doctors from rural Shandong Province, China. A multi-stage random sampling method was used to identify respondents. Conceptual content analysis together with Colaizzi's method were used to generate qualitative codes and identify themes.
Three final thematic categories emerged during the data analysis: (1) Incidence and treatment of Upper Respiratory Tract Infections (URTIs) in township hospitals and village clinics; (2) Antibiotic prescribing practices based on the clinical experience of clinicians; (3) Influence of clinical uncertainty on antibiotic prescribing. Respondents from both township hospitals and village clinics reported that URTIs were the most common reason for antibiotic prescriptions at their facilities and that clinical uncertainty appears to be an important driver for the overuse of antibiotics for URTIs. Clinical uncertainty was primarily due to: (1) Diagnostic uncertainty (establishing a relevant diagnosis is hindered by limited diagnostic resources and capacities, as well as limited willingness of patients to pay for investigations), and (2) Insufficient prognostic evidence. As a consequence of the clinical uncertainty caused by both diagnostic and prognostic uncertainty, respondents stated that antibiotics are frequently prescribed for URTIs to prevent both prolonged courses or recurrence of the disease, as well as clinical worsening, hospital admission, or complications.
Our study suggests that clinical uncertainty is a key driver for the overuse and misuse of prescribing antibiotics for URTIs in both rural township hospitals and village clinics in Shandong province, China, and that interventions to reduce clinical uncertainty may help minimize the unnecessary use of antibiotics in these settings. Interventions that use clinical rules to identify patients at low risk of complications or hospitalization may be more feasible in the near-future than laboratory-based interventions aimed at reducing diagnostic uncertainty.
本研究旨在探讨临床不确定性如何影响中国山东省农村乡镇医院医生和乡村医生的抗生素处方行为。
对中国山东省农村的30名乡镇医院医生和6名乡村医生进行了定性半结构化访谈。采用多阶段随机抽样方法确定受访者。运用概念性内容分析法和科莱齐法生成定性编码并确定主题。
数据分析过程中出现了三个最终主题类别:(1)乡镇医院和乡村诊所上呼吸道感染(URTIs)的发病率及治疗情况;(2)基于临床医生临床经验的抗生素处方行为;(3)临床不确定性对抗生素处方的影响。乡镇医院和乡村诊所的受访者均表示,URTIs是其所在医疗机构开具抗生素处方的最常见原因,临床不确定性似乎是URTIs抗生素过度使用的一个重要驱动因素。临床不确定性主要源于:(1)诊断不确定性(有限的诊断资源和能力以及患者支付检查费用的意愿有限阻碍了相关诊断的确立),以及(2)预后证据不足。由于诊断和预后不确定性导致临床不确定性,受访者表示,经常为URTIs开具抗生素以预防疾病病程延长或复发以及临床病情恶化、住院或并发症。
我们的研究表明,临床不确定性是中国山东省农村乡镇医院和乡村诊所URTIs抗生素过度使用和滥用的关键驱动因素,减少临床不确定性的干预措施可能有助于减少这些环境中抗生素的不必要使用。在不久的将来,使用临床规则识别并发症或住院风险较低患者的干预措施可能比旨在减少诊断不确定性的基于实验室的干预措施更可行。
