Protocol of a randomized controlled trial on the effectiveness and cost-effectiveness of the PLACES intervention: a supported employment intervention aimed at enhancing work participation of unemployed and/or work-disabled cancer survivors.

BACKGROUND: Approximately onethird of cancer survivors encounter challenges reintegrating into the workforce, often experiencing involuntary unemployment and/or partial or full work disability following diagnosis and treatment. Returning to paid employment presents evident challenges due to uncertainties regarding work ability, perceived employer discrimination, and a lack of support, thereby risking social exclusion. However, interventions addressing return to paid employment among unemployed and/or work-disabled cancer survivors are scarce. Here, we describe the protocol of a randomized controlled trial (RCT), including a process and economic evaluation, evaluating the effectiveness and cost-effectiveness of the PLACES (unemPLoyed cAnCEr survivors Support) intervention aimed at supporting unemployed and/or work-disabled cancer survivors returning to paid employment. METHODS: A two-armed RCT with a 12-month follow-up period will be conducted. Eligible participants: (1) are of working age (18-65 years), (2) are diagnosed with cancer between 6 months and 10 years ago, (3) are unemployed and/or partially or fully work-disabled, (4) have completed cancer treatment, and (5) are seeking paid employment and are motivated to initiate work immediately. Participants will primarily be identified through the Dutch Social Security Agency and the Netherlands Cancer Registry and recruited via healthcare professionals. Participants randomly allocated to the intervention group (n = 82) will receive the PLACES intervention: a tailored supported employment intervention based on the principles of Individual Placement and Support (IPS). This includes support in seeking, returning to, and maintaining paid employment. Participants allocated to the control group (n = 82) will receive care as usual. All participants will be asked to complete questionnaires, at baseline (T0), and after 3 (T1), 6 (T2), and 12 (T3) months of follow-up. The primary outcome is paid employment [yes/no]. Secondary outcomes are time until paid employment, change in working hours, work ability, quality of (working) life, and self-efficacy regarding return to work. Additionally, process and economic evaluations will be conducted. DISCUSSION: We hypothesize that the PLACES intervention will be effective in obtaining paid employment, enhancing work ability, and improving quality of life. In addition, we expect the intervention to be cost-effective. If proven effective and cost-effective, actions should be taken to implement the intervention in usual care.

Self-reported work ability in breast cancer survivors; a prospective cohort study in the Netherlands.

PURPOSE: To evaluate patient-reported work ability of breast cancer patients, to compare scores with the Dutch general population, and to identify determinants of reduced work ability in breast cancer patients. METHODS: In a prospective cohort study, we identified 939 patients <67 years. Employed patients filled out the Work Ability Index (WAI) questionnaire before the start of radiotherapy treatment (baseline) and at 6, 18, and 30 months. Work ability was compared with a matched Dutch cancer-free population (n=3,641). The association between (clinical) characteristics and work ability over time was assessed using mixed-effects models. RESULTS: At baseline, 68% (n=641) of the respondents were employed and 64% (n=203) were employed at 30 months. Moderate or poor work ability was reported by 71% of patients at baseline, by 24% of the patients at 30 months and by 14% of the general population. Axillary lymph node dissection, (neo)adjuvant chemotherapy and locoregional radiotherapy were associated with reduced work ability. After 30 months, 18% of employed patients reported to have reduced their working hours, made substantial modifications to their work or were unable to work. CONCLUSION: Patient-reported work ability is strongly reduced during breast cancer treatment. Thirty months after treatment the proportion of women reporting poor or moderate work ability remains higher compared to the general population. Even though the proportion of women with paid employment is rather stable over time, substantial amendments in work are needed in 18% of patients. These findings emphasize the importance of informing patients on potential changes in work ability to allow shared decision making.
