Multimorbidity clusters among long-term breast cancer survivors in Spain: Results of the SURBCAN study.

The disease management of long-term breast cancer survivors (BCS) is hampered by the scarce knowledge of multimorbidity patterns. The aim of our study was to identify multimorbidity clusters among long-term BCS and assess their impact on mortality and health services use. We conducted a retrospective study using electronic health records of 6512 BCS from Spain surviving at least 5 years.

Use of health services among long-term breast cancer survivors in Spain: longitudinal study based on real-world data.

Purpose: This study aimed to evaluate health service utilization in Spain among long-term breast cancer survivors and to compare it with that among women with no history of breast cancer.

Methods: Study based on the SURBCAN cohort includes a sample of long-term breast cancer survivors and a sample of women without breast cancer from 5 Spanish regions. Healthcare utilization was assessed through primary care, hospital visits, and tests during the follow-up period (2012 to 2016) by using electronic health records.

Use of real-world data to study health services utilisation and comorbidities in long-term breast cancer survivors (the SURBCAN study): study protocol for a longitudinal population-based cohort study.

Introduction: Breast cancer has become a chronic disease due to survival improvement and the need to monitor the side effects of treatment and the disease itself. The aim of the SURBCAN study is to describe comorbidity, healthcare services use and adherence to preventive recommendations in long-term breast cancer survivors and to compare them with those in women without this diagnosis in order to improve and adapt the care response to this group of survivors.

Methods And Analysis: Population-based retrospective cohort study using real-world data from cancer registries and linked electronic medical records in five Spanish regions.
