To assess the impact of medication frequency illustrations in patient education for use in the developing world.
This was a randomized controlled trial of a study population of patients undergoing cataract surgery in St/Louis du Nord, Haiti. Patients and accompanying family members were randomized prior to surgery to receive either standard oral post/operative instructions or oral instructions with detailed illustrations regarding the morning, noon, evening, and bedtime use of topical antibiotic and steroid drops. On postoperative day 1, patients and enrolled family members were questioned regarding when and how often the patient was to use his or her eye drops by a blinded examiner, and results were compiled.
Of the 65 patients enrolled in the study 32 patients were randomized to the oral group, 33 were randomized to the illustration group. The morning recall was 76% in the illustration group and 50% in the oral group without illustrations (p = 0.0259). Bedtime recall was 67% in the illustration group and 38% in the oral group (p = 0.0139). There was a statistically significant improvement in recall for the illustration group with the morning and bedtime doses. There was a trend in favor of the illustration group on the afternoon and evening doses; however this was not statistically significant.
Illustrations appear to be a useful adjunct in explaining complex medication regimens to patients in the developing world where cultural and language barriers can be difficult to bridge. This better understanding could translate into improved medication compliance and outcomes.
评估用药频率图示在发展中国家患者教育中的作用。
这是一项针对海地圣路易杜北接受白内障手术患者的随机对照试验。患者及其陪同家属在手术前被随机分组，分别接受标准的口服术后指导或带有关于局部用抗生素和类固醇滴眼液早晨、中午、晚上及睡前使用详细图示的口服指导。术后第1天，由一名不知情的检查者询问患者及其登记的家属患者何时以及多久使用一次眼药水，并汇总结果。
该研究共纳入65例患者，32例被随机分配至口服组，33例被随机分配至图示组。图示组早晨用药的记忆率为76%，无图示的口服组为50%（p = 0.0259）。图示组睡前用药的记忆率为67%，口服组为38%（p = 0.0139）。图示组在早晨和睡前剂量的记忆方面有统计学显著改善。下午和晚上剂量方面有倾向于图示组的趋势；然而这在统计学上不显著。
在文化和语言障碍可能难以跨越的发展中国家，图示似乎是向患者解释复杂用药方案的有用辅助手段。这种更好的理解可能转化为更好的用药依从性和治疗效果。
