Background Intermediate and high-risk non-muscle-invasive bladder cancer (NMIBC) is typically managed with transurethral resection of the bladder tumour (TURBT) followed by intravesical Bacillus Calmette–Guérin (BCG) immunotherapy; however, NMIBC patients can become refractory or unresponsive to BCG treatment, and/or progress to muscle-invasive bladder cancer (MIBC). Healthcare resource utilization (HCRU) and costs in these patient populations are high. Methods A retrospective longitudinal cohort design of adult (≥18 years) patients with bladder cancer and BCG treatment (01/01/2012–31/12/2017) was conducted using data from a representative subset of the German statutory health insurance database. During the follow-up period after last BCG, patients were categorized into subgroups of No further NMIBC treatment, Continuous treatment for NMIBC , or MIBC evidence ; HCRU and costs were tabulated for each subgroup and for the entire cohort. Results A total of 1049 patients met the study inclusion criteria (mean age, 70.9 years; 84.8% male). Across the different subgroups, patients showing MIBC evidence had more than two times higher hospitalization rates compared to the other subgroups. Overall, the entire BCG-treated cohort’s total direct medical cost including hospitalizations, outpatient care and drugs was €33.9 million and €9250 per patient-year. Cost for patients with MIBC evidence was much higher, at €17,983 per patient-year, than patients with No further NMIBC treatment (€6617) and patients with Continuous treatment for NMIBC (€7786). Across the subgroups, hospitalization was the largest driver of cost and contributed the most to cost for those with MIBC evidence . Conclusion The overall cost burden of this BCG-treated cohort of 1049 patients is high (€38 million whereof 4.1 million are indirect costs) over a mean follow-up of 3.9 years; economic burden is especially substantial for patients who fail BCG treatment and those who progress.
Objectives The treatments for high-grade non-muscle invasive bladder cancer (NMIBC) vary between bladder preserving intravesical approaches and radical cystectomy. The impact of these treatments on health-related quality of life may vary widely. The purpose of this study was to elicit the general public’s perspective on quality of life, measured as utility scores associated with treatment for Bacillus Calmette-Guerin (BCG)-unresponsive NMIBC and disease progression, for supporting economic evaluation of newly developed treatments for NMIBC. Materials and Methods Part I involved the development and testing of health states describing NMIBC, which was informed by a rapid review, expert input and a patient advisor. Part II involved elicitation of societal utility values for the different health states. Time trade-off (TTO) interviews were conducted with members of the UK general public. Five health states described different NMIBC scenarios including disease recurrence and progression. Participants ranked each health state, followed by the TTO valuation exercise. Descriptors included NMIBC symptom severity, impact and treatment characteristics. Results In total, 202 members of the general public participated. The mean age was 46 (standard deviation [SD] 14.6) years. Sample mean (SD) EQ-5D-5L visual analogue scale (VAS) and index scores were 83.2 (12.3) and 0.89 (0.18), respectively. Mean utilities were 0.781 for No High-Grade Recurrence, 0.586 for High-Grade Recurrence, 0.572 for > 1-Year Post-cystectomy and 0.283 for metastatic disease. The First Year Post-cystectomy path health state had a mean utility of 0.288. Pairwise comparisons found statistically significant differences between utilities ( p < 0.001), except between High-Grade Recurrence and > 1-Year Post-cystectomy ( p = 0.524). There were significant differences in utility scores by age and employment status. Conclusion This study provides utility scores for health states describing living with NMIBC, which is associated with a significant health-related quality-of-life burden. These values address an existing gap in available data and have the potential to be used in models evaluating the cost-effectiveness of both current and newly developed treatments for bladder cancer.
