Abstract
Introduction Family planning is fundamental in primary care (PC), and informed counseling helps to guide contraceptive choices. Combined hormonal contraceptives (CHC) pose cardiovascular risks, particularly when combined with smoking. According to the World Health Organization, the recommended global clinical decision is to refrain from employing CHC in female smokers aged 35 or older. This study aimed to improve contraception prescription for female smokers aged 35-54 in PC. Methods This study was conducted in a Portuguese Family Health Unit (FHU) from October 2021 to August 2022, and it followed the Standards for Quality Improvement Reporting Excellence (SQUIRE 2.0) guidelines and the Plan-Do-Study-Act approach. Female smokers aged 35-54 were included and evaluated in three moments: baseline evaluation (October 2021), intermediate evaluation (February 2022), and post-intervention evaluation (August 2022). Interventions involved educating medical staff, creating patient awareness campaigns, and evaluating contraceptive methods. The established quality-defining goal was to decrease the prevalence of female smokers aged 35 or above using CHC to ≤5%. Results CHC prevalence among smoking women aged 35-54 decreased from 16.4% to 8.5% after nine months of the initial intervention. There was an increase in progestogen-only methods usage over time, from 25.7% to 34.0%. Discussion Despite not fully achieving the predefined goal, interventions led to a substantial reduction of CHC use among smoking women aged 35-54. Collaborative efforts between healthcare professionals and patients played a pivotal role in optimizing care and reducing cardiovascular risk. This study underscores the importance of continuous quality improvement, collaborative interventions, and knowledge updates in Family Medicine practice. While conducted in a single FHU, the intervention's multidimensional approach holds the potential for broader applicability. Conclusion In the future, healthcare teams should continue to reflect on achieved results, maintain knowledge, and empower patients in contraceptive method choices. The study contributes to improved care quality and highlights the positive impact on medical practice and patient outcomes.
