Abstract

Background and Objectives

Treatment of colorectal cancer (CRC) can have prolonged effects on health-related quality of life (HRQOL). Using the Medicare Health Outcomes Survey (MHOS), this study examines HRQOL outcomes among those undergoing CRC treatment and those who completed CRC treatment.

Methods

We performed a paired longitudinal retrospective cohort study of Medicare Advantage enrollees ≥ 65 years of age who completed the baseline and follow-up MHOS from 2016 to 2020 and answered survey questions regarding current CRC treatment. Outcomes included Physical Component Summary (PCS) scores and Mental Component Summary (MCS) scores. Multivariable logistic regression analyses were used.

Results

574 Respondents met the inclusion criteria. Those currently undergoing treatment for CRC had significantly lower PCS scores (β coefficient −3.08 points, p < 0.001) and significantly lower MCS scores (β coefficient −1.40 points, p = 0.008) at follow-up compared to when they were not undergoing CRC treatment at baseline. Respondents who completed CRC treatment had PCS and MCS scores that remained similar over time (β coefficient 0.54 points, p = 0.466 and 0.07 points, p = 0.924, respectively).

Discussion

Treatment of CRC negatively influences HRQOL. These findings emphasize the importance of informing patients of the long-term effects of CRC treatment and support the implementation of interventions aimed at providing sustained recovery throughout the survivorship continuum.

Data Availability Statement

The data underlying this study are derived from the Medicare Health Outcomes Survey (MHOS), which is available through the Centers for Medicare & Medicaid Services (CMS). Access to the Medicare HOS data is restricted and requires approval from CMS to ensure compliance with legal and ethical standards, including the protection of patient confidentiality. Researchers may apply for access to the Medicare HOS data by submitting a data use agreement and following CMS's procedures.
