Stepped care targeting psychological distress in head and neck cancer and lung cancer patients: which groups specifically benefit? Secondary analyses of a randomized controlled trial.

PURPOSE: Stepped care (SC), consisting of watchful waiting, guided self-help, problem-solving therapy, and psychotherapy/medication is, compared to care-as-usual (CAU), effective in improving psychological distress. This study presents secondary analyses on subgroups of patients who might specifically benefit from watchful waiting, guided self-help, or the entire SC program. METHODS: In this randomized controlled trial, head and neck and lung cancer patients with distress (n = 156) were randomized to SC or CAU. Univariate logistic regression analyses were performed to investigate baseline factors associated with recovery after watchful waiting and guided self-help. Potential moderators of the effectiveness of SC compared to CAU were investigated using linear mixed models. RESULTS: Patients without a psychiatric disorder, with better psychological outcomes (HADS: all scales) and better health-related quality of life (HRQOL) (EORTC QLQ-C30/H&N35: global QOL, all functioning, and several symptom domains) were more likely to recover after watchful waiting. Patients with better scores on distress, emotional functioning, and dyspnea were more likely to recover after guided self-help. Sex, time since treatment, anxiety or depressive disorder diagnosis, symptoms of anxiety, symptoms of depression, speech problems, and feeling ill at baseline moderated the efficacy of SC compared to CAU. CONCLUSIONS: Patients with distress but who are relatively doing well otherwise, benefit most from watchful waiting and guided self-help. The entire SC program is more effective in women, patients in the first year after treatment, patients with a higher level of distress or anxiety or depressive disorder, patients who are feeling ill, and patients with less speech problems. TRIAL: NTR1868.

Cost-Utility of Stepped Care Targeting Psychological Distress in Patients With Head and Neck or Lung Cancer.

Purpose A stepped care (SC) program in which an effective yet least resource-intensive treatment is delivered to patients first and followed, when necessary, by more resource-intensive treatments was found to be effective in improving distress levels of patients with head and neck cancer or lung cancer. Information on the value of this program for its cost is now called for. Therefore, this study aimed to assess the cost-utility of the SC program compared with care-as-usual (CAU) in patients with head and neck cancer or lung cancer who have psychological distress. Patients and Methods In total, 156 patients were randomly assigned to SC or CAU. Intervention costs, direct medical costs, direct nonmedical costs, productivity losses, and health-related quality-of-life data during the intervention or control period and 12 months of follow-up were calculated by using Trimbos and Institute of Medical Technology Assessment Cost Questionnaire for Psychiatry, Productivity and Disease Questionnaire, and EuroQol-5 Dimension measures and data from the hospital information system. The SC program's value for the cost was investigated by comparing mean cumulative costs and quality-adjusted life years (QALYs). Results After imputation of missing data, mean cumulative costs were -€3,950 (95% CI, -€8,158 to -€190) lower, and mean number of QALYs was 0.116 (95% CI, 0.005 to 0.227) higher in the intervention group compared with the control group. The intervention group had a probability of 96% that cumulative QALYs were higher and cumulative costs were lower than in the control group. Four additional analyses were conducted to assess the robustness of this finding, and they found that the intervention group had a probability of 84% to 98% that cumulative QALYs were higher and a probability of 91% to 99% that costs were lower than in the control group. Conclusion SC is highly likely to be cost-effective; the number of QALYs was higher and cumulative costs were lower for SC compared with CAU.
