Healthcare use, sickness absence, and disability pension among colorectal cancer survivors and population references in Sweden

Abstract

Background: Colorectal cancer (CRC) has negative long-term impacts on survivors’ health and work capacity. We aimed to investigate specialized healthcare use and sickness absence and disability pension among CRC survivors and matched references. Material and methods: In this longitudinal register-based cohort study, 6679 patients with a first primary CRC in 2008–2011 (when aged 18–62) and 26,716 CRC-free matched references were followed from 2 years before up to 5 years after diagnosis date. Mean numbers of hospital days and outpatient visits were illustrated for survivors and references for the 7-year period. Crude and adjusted mean numbers of sickness absence/disability pension net days were calculated for post-diagnosis Years 3 and 5. Results: Survivors’ healthcare use was higher compared to their references throughout the 7 years around CRC diagnosis and was mostly due to CRC, secondary neoplasms, and digestive disorders. In Year 5, survivors had 1.94 mean outpatient visits and 2.13 mean inpatient days (compared to 1.00 and 0.82 for references, respectively). Survivors’ adjusted mean sickness absence/disability pension days amounted to 85 d in Year 3 and 77 in Year 5 (compared to 57 and 54 d in the references). Higher mean number of future days was found among women, lower-educated, foreign-born, with previous comorbidities or previous mental disorders. Those with many sickness absence days in 2 years pre-diagnosis had the highest number of future sickness absence/disability pension days. Conclusions: Post-diagnostic healthcare use remained high among CRC survivors, mostly due to cancer (CRC and other neoplasms) and digestive diagnoses. Their sickness absence and disability pension decreased gradually over the period but remained higher than among references. Pre-morbid characteristics may be used in early work-related clinical planning for the survivors.
