Measurement and evaluation of quality of life and well-being in individuals having or having had fertility problems: a systematic review

__Objectives:__ The aims of this study were: (1) to identify which measurement instruments are used in practice to assess the quality of life or well-being of individuals with and without (sub)fertility; (2) to describe the design and outcomes of studies comparing quality of life or well-being of individuals with and without fertility problems; and (3) to determine which of the outcomes of the identified studies could be used in cost-utility studies. __Methods:__ A systematic literature review was performed of studies published before July 2018, using multiple databases. Included studies investigated (health-related) quality of life or well-being of individuals with fertility problems. The applied instruments were assessed, as were the outcomes and suitability for use in cost-utility studies. __Results:__ Twenty-six studies met the inclusion criteria. Twelve distinct instruments of measurement were applied: two generic quality-of-life instruments, five generic well-being instruments and five disease-specific instruments. Most studies found negative associations in one or more domains assessing fertility problems and quality of life or well-being. However, two studies found the opposite. None of the studies reported outcomes relevant for cost-utility studies. __Conclusion:__ Quality of life and well-being related to having fertility problems are regularly studied. However, the reported information is not suitable for use in cost-utility studies. There is a clear need for studies investigating the impact of fertility problems on quality of life in a way that outcomes can be compared across studies and disease areas

Cost‐effectiveness of Anti‐CD19 chimeric antigen receptor T‐Cell therapy in pediatric relapsed/refractory B‐cell acute lymphoblastic leukemia. A societal view

Introduction: In several studies, the chimeric antigen receptor T-cell therapy tisagenlecleucel demonstrated encouraging rates of remission and lasting survival benefits in pediatric patients with relapsed/refractory (r/r) acute lymphoblastic leukemia (ALL). We assessed the cost-effectiveness of tisagenlecleucel (list price: 320 000 EUR) among these patients when compared to clofarabine monotherapy (Clo-M), clofarabine combination therapy (Clo-C), and blinatumomab (Blina) from both a healthcare and a societal perspective. We also assessed future medical and future non-medical consumption costs. Methods: A three-state partitioned survival model was used to simulate a cohort of pediatric patients (12 years of age) through different disease states until the end of life (lifetime horizon). Relevant outcomes were life years, quality-adjusted life years (QALYs), healthcare costs, societal costs, and the incremental cost-effectiveness ratio (ICER). Uncertainty was explored through deterministic and probabilistic sensitivity analyses as well as through several scenario analyzes. Results: Total discounted costs for tisagenlecleucel were 552 679 EUR from a societal perspective, which was much higher than the total discounted costs from a healthcare perspective (ie, 409 563 EUR). Total discounted societal costs for the comparator regimens ranged between 160 803 EUR for Clo-M and 267 259 EUR for Blina. Highest QALYs were estimated for tisagenlecleucel (11.26), followed by Blina (2.25), Clo-C (1.70) and Clo-M (0.74). Discounted societal ICERs of tisagenlecleucel ranged between 31 682 EUR/QALY for Blina and 37 531 EUR/QALY for Clo-C and were considered cost-effective with a willingness-to-pay (WTP) threshold of 80 000 EUR/QALY. None of the scenarios exceeded this threshold, and more than 98% of the iterations in the probabilistic sensitivity analysis were cost-effective. Discussion: At the current price and WTP threshold, tisagenlecleucel is cost-effective from both a healthcare and a societal perspective. Nevertheless, long-term effectiveness data are needed to validate the several assumptions that were necessary for this model
