BACKGROUND: In patients with pulmonary arterial hypertension (PAH), the use of disease-specific therapies (i.e., endothelin receptor antagonists, phosphodiesterase type-5 inhibitors, soluble guanylate cyclase stimulators, prostacyclins, and prostanoids) has been associated with disease improvement and decreased mortality risk. We aimed to quantify the adherence and discontinuation rates for patients prescribed PAH-specific therapies.
METHODS: We performed a systematic review via searching MEDLINE, EMBASE, and the Cochrane Library from their inception to 4 March 2022 for observational studies published in English that reported data on adherence to and persistence with PAH-targeted therapies. Random-effects meta-analysis was performed to explore average adherence and discontinuation rates.
RESULTS: In all, 14 studies involving 14,861 individuals prescribed PAH-targeted therapies were included. The overall pooled proportion of patients adherent to their PAH-targeted medications was 60.9% (95% confidence interval [CI] 52.3-69.1%). The pooled proportions of patients adherent in questionnaire-based studies and in studies using prescription/dispensing data were 52.9% (95% CI 48.9-56.9%) and 62.9% (95% CI 53.1-72.2%), respectively. The pooled proportion of patients who discontinued their PAH-targeted medications was 42.3% (95% CI 31.6-53.3). Factors reported to impact adherence included administration frequency, length of time on treatment, co-payment, and occurrence of adverse events.
CONCLUSIONS: In the real world, a considerable proportion of patients prescribed PAH-specific therapies were non-adherent or discontinued. As diverse factors may influence treatment adherence, multifaceted interventions are needed to address this trend in order to improve patient outcomes.
REGISTRATION: The systematic review protocol was registered in the PROSPERO database (CRD42022316638).
