Assessment of medication adherence, medication safety awareness and medication practice among patients with lung cancer: A multicentre cross‐sectional study

Abstract

Abstract Objectives We aimed to explore the current status of medication adherence, safety awareness and practice among patients with lung cancer. Methods We conducted a questionnaire‐guided cross‐sectional study in Xi'an, Yulin, Hanzhong and Weinan in Shaanxi Province, China, from April to June 2021 for a period of 3 months. The study questionnaire was developed according to previous related studies reported in the literature, and includes basic demographic information and patients' medication safety questions. The data were double‐entered using EpiData 3.1 software; descriptive statistics, t‐test, analysis of variance, the Kruskal–Wallis test and the Mann–Whitney U‐test were performed to analyse the data. Results A total of 567 participants were included, and 409 valid questionnaires were finally completed, with an effective response rate of 72.13%. More than 80% of patients showed good medication adherence; the average adherence score was 22 ± 2.68 of 25. The average score for medication safety awareness was 16.40 ± 4.41, which was significantly lower than that of medication adherence (p < .001). Only 22.74% of patients always checked their medicines before a nurse administered them; 17.60% of patients never checked their medicines. Few patients actively consulted an health care professional to understand safety information before taking a medication. A significant difference existed in safety awareness scores among age groups (p = .039) and geographic regions (p < .001). Patients with three or more comorbidities had the lowest awareness scores (p = .027). Conclusion We found that patients with lung cancer showed better medication adherence, but their awareness about medication safety was poor. Older patients, those with comorbidities and patients in regions with poor medical resources may have worse awareness about safety. Current medication education for patients should not only aim to improve adherence but should also encourage patients to take greater responsibility for their own safety and to actively participate in their medication safety. Greater systematic and individualized medication safety information is needed for older patients, those with more comorbidities and patients in areas with poor medical resources. Patient Contribution We conducted a questionnaire‐guided cross‐sectional study on hospitalized lung cancer patients in Shaanxi Province to explore the patients' practices related to safety medication, including medication adherence and medication safety awareness.
