Abstract

BACKGROUND

Achieving good medication adherence is a major challenge for patients with chronic conditions. Our study aimed to assess the Threshold for Unacceptable Risk of Non-adherence (TURN), defined as the threshold at which physicians consider the health risks incurred by patients due to medication non-adherence unacceptable, for the most commonly prescribed drugs in France.

METHODS

We conducted an online study using a crowdsourcing approach among French general practitioners and specialists from September 2016 to August 2017. Physicians assessed the TURN for various levels of missed doses by evaluating a series of randomly presented clinical vignettes, each presenting a given medication with a given therapeutic indication. For each "drug-indication group" (i.e., all drugs from the same pharmacological class with a similar therapeutic indication): 1) we described the distribution of physicians' assessments, 2) we provided a summary estimate of the TURN, defined as the frequency of missed doses above which 75% of the physicians' assessments were located; 3) we computed the number of pill boxes reimbursed in France in 2016 to put our results into context.

RESULTS

We collected a total of 5365 assessments from 544 physicians, each of whom evaluated a random sample among 528 distinct clinical vignettes. Estimates of the TURN varied widely across drug-indication groups, ranging from risk considered unacceptable with 1 daily dose missed per month (e.g., insulin for diabetes) to risk always considered acceptable (e.g., anti-dementia drugs). Drugs with an estimated TURN of over one missing daily dose per week represented 44.9% of the prescription volume of the medications assessed in our study.

CONCLUSIONS

According to physicians, the impact of non-adherence may vary greatly. Patient-physician discussions on the variable consequences of non-adherence could lead to a paradigm shift by seeking to reach "optimal adherence" depending on drugs rather than unrealistic "perfect adherence" to all drugs.

摘要

背景

对于慢性病患者来说，实现良好的用药依从性是一项重大挑战。我们的研究旨在评估不可接受的药物不依从风险阈值（TURN），即医生认为因药物不依从而导致患者健康风险不可接受的阈值，这是法国最常用的药物。

方法

我们于 2016 年 9 月至 2017 年 8 月采用众包方式，对法国全科医生和专科医生进行了一项在线研究。医生通过评估一系列随机呈现的临床病例来评估各种漏服剂量水平的 TURN，每个病例呈现一种特定的药物和特定的治疗指征。对于每个“药物-适应证组”（即，具有相似治疗指征的同一药理学类别的所有药物）：1）我们描述了医生评估的分布；2）我们提供了 TURN 的汇总估计值，定义为 75%的医生评估值所在的漏服剂量频率；3）我们计算了 2016 年在法国报销的药盒数量，以便将我们的结果置于上下文中。

结果

我们从 544 名医生中收集了总共 5365 项评估，每位医生评估了 528 个不同临床病例中的随机样本。药物-适应证组之间的 TURN 估计值差异很大，从每月漏服 1 次剂量就认为风险不可接受（例如，糖尿病用胰岛素）到始终认为风险可接受（例如，抗痴呆药物）不等。预计 TURN 超过每周漏服 1 次剂量的药物占我们研究中评估药物处方量的 44.9%。
