Abstract

Objective: Optimal pharmacological treatment (OPT) for peripheral arterial occlusive disease (PAOD) includes prescription of lipid lowering drugs, antithrombotics, and antihypertensives to symptomatic patients affected by intermittent claudication or chronic limb threatening ischaemia. This study sought to determine sex disparities and time trends in prescription of OPT in this population (clinicaltrials.gov NCT03909022).

Methods: Using data from the second largest insurance fund in Germany, BARMER, data on patients with an index admission for symptomatic PAOD between 1 January 2010 and 30 June 2018 with follow up until the end of 2018 were analysed. Sex disparities in post-discharge prescription status six months after index admission were tested and adjusted for patient and healthcare variables using bivariable tests and logistic regression analysis. Time trends in the prescription prevalence of OPT were analysed and tested.

Results: There were 83 867 patients (mean age 71.9 years and 45.8% women) eligible for inclusion in the study. When compared with men, women had lower rates of prior outpatient care for PAOD (39.8% vs. 47.0%), were admitted more often with ischaemic rest pain (13.9% vs. 10.4%) and were older (74 vs. 70 y). After discharge, women had a lower rate of prescriptions for lipid lowering drugs (52.4% vs. 59.9%), while they received antihypertensive drugs more often (86.7% vs. 84.1%). We found evidence for a lower prescription prevalence of OPT in females (37.0% vs. 42.7%). Differences in patient and healthcare variables (e.g. demographics, comorbidities, prior treatment) between women and men explained 56% of this gap. The sex prescription gap did not narrow over time despite an overall upward trend in prescription prevalence for both women and men.

Conclusion: Although presenting older and with more severe symptoms at the index admission for PAOD, women have a lower prescription prevalence of OPT compared with men, particularly with respect to lipid lowering drugs.
