Factors influencing medication adherence for deep vein thrombosis prevention in post-discharge patients after joint replacement surgery: a qualitative study based on Protection Motivation Theory.
Article in BMJ open, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesThis study aims to identify factors influencing medication adherence for deep vein thrombosis (DVT) prophylaxis in post-discharge patients after joint replacement surgery using Protection Motivation Theory (PMT).
designThis study employed qualitative semi-structured interviews with patients discharged after hip or knee replacement surgery.
settingUsing purposive sampling to ensure a diverse representation of patient profiles, participants were recruited from patients who underwent total knee replacement surgery from April 2024 to May 2024 and were discharged 1-month prior.
participants12 patients who had undergone total knee replacement surgery participated in the study. The median (IQR) age of participants was 57.5 (55-67.25) years. ANALYSIS: Semi-structured interviews were conducted via online video calls. These interviews were audio recorded and transcribed verbatim. Data were analysed using Colaizzi's seven-step method. Themes were identified based on the dimensions of the PMT: susceptibility, severity, internal rewards, external rewards, response efficacy, self-efficacy and response costs. Two researchers independently coded and extracted themes, with discrepancies resolved through team discussions and verification with respondents.
resultsParticipants acknowledged the importance of adhering to anticoagulant medication to prevent DVT and its complications, understanding the severe consequences, such as the life-threatening nature of pulmonary embolism and the impact on daily activities. Perceived health status influenced adherence, with some participants feeling their good health negated the need for anticoagulants. External factors, including the desire to avoid side effects and financial constraints, also played significant roles in adherence decisions. Belief in the effectiveness of anticoagulants motivated adherence, but confidence in managing medication varied among participants. Practical barriers such as physical limitations and psychological burdens significantly impacted adherence.
conclusionsImproving medication adherence requires a multifaceted approach addressing cognitive, motivational and practical barriers. Continuous education, financial assistance, support systems and tailored interventions are crucial. PMT provides a robust framework for understanding and enhancing adherence behaviours, ultimately improving health outcomes in post-discharge joint replacement patients.
