Costs from a healthcare and societal perspective among cancer patients after total laryngectomy: are they related to patient activation?

Purpose: The aim of this study is to investigate the associations between patient activation and total costs in cancer patients treated with total laryngectomy (TL).
Methods: All members of the Dutch Patients' Association for Laryngectomees were asked to participate in this cross-sectional study. TL patients who wanted to participate were asked to complete a survey. Costs were measured using the medical consumption and productivity cost questionnaire and patient activation using the Patient Activation Measure (PAM). Sociodemographic and clinical characteristics were self-reported, and health status measured using the EQ-5D. The difference in total costs from a healthcare and societal perspective among four groups with different PAM levels were compared using (multiple) regression analyses (5000 bootstrap replications).
Results: In total, 248 TL patients participated. Patients with a higher (better) PAM (levels 2, 3, and 4) had a probability of 70, 80, and 93% that total costs from a healthcare perspective were lower than in patients with the lowest PAM level (difference €-375 to €-936). From a societal perspective, this was 73, 87, and 82% (difference €-468 to €-719). After adjustment for time since TL, education, and sex, the probability that total costs were lower in patients with a higher PAM level compared to patients with the lowest PAM level changed to 62-91% (healthcare) and 63-92% (societal). After additional adjustment for health status, the probability to be less costly changed to 35-71% (healthcare) and 31-48% (societal).
Conclusions: A better patient activation is likely to be associated with lower total costs from a healthcare and societal perspective.
