IntroductionVarious treatment options are available for metastatic hormone-sensitive prostate cancer. This study aimed to quantify how men with prostate cancer in the United Kingdom (UK), Germany, and Spain perceive the risks and benefits of hypothetical abiraterone acetate plus prednisone treatment and docetaxel-based chemotherapy treatment options.MethodsA targeted literature review, exploratory interviews with prostate cancer patients and oncologists, and pre-test interviews were used to develop a discrete choice experiments (DCE). The final DCE included 32 choice sets, selected using a main-effects orthogonal design, divided into two survey blocks. Paired profiles presented hypothetical treatments for prostate cancer through six attributes that could be presented at two or four levels each. Preference estimates were estimated using a conditional logit regression model. Preference results were stratified by cancer stage.ResultsA total of 152 participants (mean age 69 years) completed the DCE in the UK, Germany, and Spain. Treatment effectiveness was the main concern for the patients (difference in preference estimates between 8 and 32 months 1.443). Participants wanted to avoid pain that was not well controlled (preference dummy coding estimate − 1.157). Participants valued a change from an oral medication to an intravenous treatment (change in preference estimate − 0.416) more negatively than a change from a 1% to a 5% risk of infection (change in preference estimate − 0.313).ConclusionsThis study shows that treatment effectiveness and pain control were the most important attributes for patients with prostate cancer. These two attributes influenced more than 50% of their decision-making in this study. The risk of fatigue and mode of administration were least prioritised by patients. This study highlights the relative importance that Spanish, German, and British patients place on various aspects of treatment options for prostate cancer. Understanding patient preference and taking them into consideration shall help physicians when developing their treatment strategies for their patients.FundingJanssen.Electronic supplementary materialThe online version of this article (10.1007/s12325-018-0861-3) contains supplementary material, which is available to authorized users.
Patient reports or ratings are essential for measuring the quality of patient care. Measures designed for this purpose tend to focus on the processes and structures of care rather than the outcomes of it. The latter is arguably the most valid indicator of the quality of care patients receive. Typically this information is gathered by probing patient satisfaction with treatment as part of an investigation of satisfaction with hospital care. More recently patient ratings of the outcome of treatment have been obtained to measure treatment efficacy in clinical trials. However, a more direct approach is to ask patients to assess the benefit of treatment on their current health status. We performed a structured literature review on patient reported satisfaction with outcomes of treatment and direct patient assessments of the same. The purpose of this was to identify suitable candidate questions for a short instrument to tap patient evaluations of in-patient hospital interventions. Articles were included if they dealt with patient satisfaction or patient assessment of the outcomes of treatment. Articles were excluded if they dealt more generally with patient satisfaction with care. We identified 169 papers, 79 were included in the review. The findings of this review suggest that there are a number of benefits of directly asking patients to assess the outcome of hospital treatment. Importantly this approach reflects outcomes relevant to the patient and is also more likely to reflect patient report in routine clinical practice. There is also evidence that such approaches have face validity and construct validity. The problems associated with this approach (i.e. response bias), are those common to patient reported outcome surveys, but employing appropriate strategies can minimize them. Furthermore, employing a simple set of questions that asks patients to assess the outcomes of treatment they receive can be time and resource efficient in comparison to administering lengthy measures. This approach could be tested for potential generic use as an evaluative measure for patients in hospital settings.
Purpose To capture UK societal health utility values for high-risk metastatic hormone-sensitive prostate cancer (mHSPC) and the disutility associated with treatment-related adverse events (AEs) to inform future cost–utility analyses. Methods A literature review, and patient and clinical expert interviews informed the development of health states characterising mHSPC symptoms and the impact of treatment-related AEs on health-related quality of life (HRQL). Three base health states were developed describing a typical patient with high-risk mHSPC: receiving androgen deprivation therapy (ADT) [Base State 1]; receiving docetaxel plus ADT [Base State 2]; completed docetaxel and still receiving ADT whose disease has not yet progressed [Base State 3]. Six additional health states described treatment-related AEs. The health states were validated with experts and piloted with general public participants. Health state utilities were obtained using the time trade-off (TTO) method with 200 members of the UK general population. A generalised estimating equation (GEE) model was used to estimate disutility weights. Results Mean TTO scores for Base State 1 to 3 were 0.71 (SD = 0.26), 0.64 (SD = 0.27), and 0.68 (SD = 0.26), respectively, indicating that receiving docetaxel plus ADT was most impactful on HRQL. The GEE model indicated when compared to Base State 2 that the nausea and vomiting AE had the most impact on HRQL (− 0.21), while alopecia was least burdensome (− 0.04). Conclusions The study highlights the differences in utility between base health states and the significant impact of treatment-related AEs on the HRQL of patients with mHSPC. These findings underline the importance of accounting for impaired HRQL when assessing treatments for mHSPC.

BackgroundThis study aimed to obtain UK societal-based utility values for health states related to treatment mode of administration using Gaucher disease as the background condition.MethodsA review of relevant literature and expert clinical input informed the development of five health states characterising the impact of Gaucher disease and its management on patients’ lives. A base-state characterising the “controlled disease” was developed as well as four subsequent health states which varied in description of the method (intravenous versus oral) and frequency of treatment administration. Health state utilities were obtained using the time trade-off (TTO) method via face-to-face interviews with 100 members from the UK general population. Before the valuation exercise, participants provided informed consent, completed a demographic form and the EQ-5D, and ranked the health states from best to worst on a 0–100 visual analogue scale (VAS).ResultsMean age of the participants (n = 100) was 35 years and 66% were female. Participants reported high EQ-5D VAS (86.1) and index scores (0.95) indicating very good health status. The “controlled disease” state had the highest mean TTO-derived utility value (0.89). There was only a marginal reduction in utility for the generic state for “Oral treatment” (0.85), while the reduction was more pronounced for the generic state for “Intravenous treatment” (0.73).ConclusionsThe findings suggest that the avoidance of the need for intravenous treatment administration is associated with a notable positive increase in health-related quality of life. Patient benefit arising from less invasive treatment could be an important consideration when undertaking economic evaluation of future therapies for Gaucher disease.Electronic supplementary materialThe online version of this article (10.1186/s13023-018-0903-6) contains supplementary material, which is available to authorized users.
Introduction:Management of type 2 diabetes mellitus (T2DM) often requires intervention with oral and injectable therapies. Across National Health Service (NHS) England, injectable therapies may be initiated in secondary, intermediate or primary care. We wished to understand resource utilization, pathways of care, clinical outcomes, and experience of patients with T2DM initiated on injectable therapies.Method:We conducted three service evaluations of initiation of injectable therapies (glucagon-like peptide-1 receptor agonists (GLP-1 RAs) or basal insulin) for T2DM in primary, secondary and intermediate care. Evaluations included retrospective review of medical records and service administration; prospective evaluation of NHS staff time on each episode of patient contact during a 3-month initiation period; patient-experience survey for those attending for initiation. Data from each evaluation were analysed separately and results stratified by therapy type.Results:A total of 133 patients were included across all settings; 54 were basal-insulin initiations. After initiation, the mean HbA1c level fell for both types of therapies, and weight increased for patients on basal insulin yet fell for patients on GLP-1 RA. The mean cost of staff time per patient per initiation was: £43.81 for GLP-1 RA in primary care; £243.49 for GLP-1 RA and £473.63 for basal insulin in intermediate care; £518.99 for GLP-1 RA and £571.11 for basal insulin in secondary care. Patient-reported questionnaires were completed by 20 patients, suggesting that patients found it easy to speak to the diabetes team, had opportunities to discuss concerns, and felt that these concerns were addressed adequately.Conclusion:All three services achieved a reduction in HbA1c level after initiation. Patterns of weight gain with basal insulin and weight loss with GLP-1 RA were as expected. Primary care was less resource-intensive and costly, and was driven by lower staff costs and fewer clinic visits.
