Abstract
In the Netherlands, drug regulatory science is a vibrant national and internationally oriented community. In this review, we present the factors that have contributed to this successful collaboration between relevant stakeholders and that led to a surge of activities around how regulatory science became embedded in the ecosystem of medicines research, clinical pharmacology, policymaking and regulation. We distinguished three pivotal episodes: (i) TI Pharma Escher-project, (ii) Dutch Medicines Evaluation Board as catalyst of the big jump, and (iii) Regulatory Science Network Netherlands and multistakeholder engagement. The research agenda has been influenced by the dynamic evolution of legal frameworks in Europe, such as the EU orphan medicines legislation of 2001 and the EU pharmacovigilance legislation of 2012. All these developments have inspired and have raised pertinent regulatory sciences questions. Furthermore, clinical pharmacology as a discipline has been very influential in shaping regulatory science, contributing to discussions on the level of clinical evidence that is necessary to justify marketing approval of a new medicine. With a growing interest of multiple parties such as academics, European Medicines Agency, national agencies, patient organizations and EFPIA, connecting regulatory science activities is key.

Abstract
INTRODUCTION Stated preference studies are a valuable tool to elicit respondents' willingness to pay (WTP) for goods or services, especially in situations where no market valuation exists. Contingent valuation (CV) is a widely used approach among stated-preference techniques for eliciting WTP if prices do not exist or do not reflect actual costs, for example, when services are covered by insurance. This review aimed to provide an overview of relevant factors determining WTP for health services to support variable selection. METHODS A comprehensive systematic literature search and review of CV studies assessing determinants of WTP for health services was conducted, including 11 electronic databases. Two of the authors made independent decisions on the eligibility of studies. We extracted all determinants used and related p values for the effect sizes (e.g. reported in regression models with WTP for a health service as outcome variable). Determinants were summarised in systematic evidence tables and structured by thematic domains. RESULTS We identified 2082 publications, of which 202 full texts were checked for eligibility. We included 62 publications on 61 studies in the review. Across all studies, we identified 22 WTP determinants and other factors from 5 thematic domains: sociodemographic characteristics, perceived threat, perceived benefit, perceived barriers, and other information. CONCLUSION Our review provides evidence on 22 relevant determinants of WTP for health services, which may be used for variable selection and as guidance for planning CV surveys. Endogeneity should be carefully considered before interpreting these determinants as causal factors and potential intervention targets.

Abstract
UNLABELLED Medication errors are common in hospitals. These errors can result in adverse drug events (ADEs), which can reduce the health and well-being of patients', and their relatives and caregivers. Interventions have been developed to reduce medication errors, including those that occur at the administration stage. OBJECTIVE We aimed to elicit willingness-to-pay (WTP) values to prevent hospital medication administration errors. DESIGN AND SETTING An online, contingent valuation (CV) survey was conducted, using the random card-sort elicitation method, to elicit WTP to prevent medication errors. PARTICIPANTS A representative sample of the UK public. METHODS Seven medication error scenarios, varying in the potential for harm and the severity of harm, were valued. Scenarios were developed with input from: clinical experts, focus groups with members of the public and piloting. Mean and median WTP values were calculated, excluding protest responses or those that failed a logic test. A two-part model (logit, generalised linear model) regression analysis was conducted to explore predictive characteristics of WTP. RESULTS Responses were collected from 1001 individuals. The proportion of respondents willing to pay to prevent a medication error increased as the severity of the ADE increased and was highest for scenarios that described actual harm occurring. Mean WTP across the scenarios ranged from £45 (95% CI £36 to £54) to £278 (95% CI £200 to £355). Several factors influenced both the value and likelihood of WTP, such as: income, known experience of medication errors, sex, field of work, marriage status, education level and employment status. Predictors of WTP were not, however, consistent across scenarios. CONCLUSIONS This CV study highlights how the UK public value preventing medication errors. The findings from this study could be used to carry out a cost-benefit analysis which could inform implementation decisions on the use of technology to reduce medication administration errors in UK hospitals.

Abstract
INTRODUCTION Active surveillance pharmacovigilance is a systematic approach to medicine safety assessment and health systems strengthening, but has not been widely implemented in low- and middle-income countries. This study aimed to assess the cost effectiveness of a national active surveillance pharmacovigilance system for highly active antiretroviral therapy (HAART) compared with the existing spontaneous reporting system in Namibia. METHODS A cost-utility analysis from a governmental perspective compared active surveillance pharmacovigilance to spontaneous reporting. Data from a sentinel site active surveillance program in Namibia from August 2012 to April 2013 was projected to all HIV-infected adults initiating HAART in Namibia. Costs (pharmacovigilance program, HAART, adverse event [AE] treatment), quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratios (ICERs, dollars/QALY) were evaluated. Analysis was completed for (i) cohort analysis: a single cohort beginning HAART in 1 year in Namibia followed over their remaining lifetime, and (ii) population analysis: patients continued to enter and leave care and treatment over 10 years. RESULTS For the cohort analysis, totals were US$21,267,902 (2015 US dollars) and 116,224 QALYs for care and treatment under active surveillance pharmacovigilance versus US$15,257,381 and 116,122 QALYs for care and treatment under spontaneous reporting pharmacovigilance, resulting in an ICER of US$58,867/QALY for active surveillance compared with spontaneous reporting pharmacovigilance. The population analysis ICER was US$4989/QALY. Results were sensitive to quality of life associated with AEs. CONCLUSION Active surveillance pharmacovigilance was projected to be highly cost effective to improve treatment for HIV in Namibia. Active surveillance pharmacovigilance may be valuable to improve lives of HIV patients and more efficiently allocate health resources in Namibia.

Abstract
PURPOSE Active surveillance pharmacovigilance systems better estimate the burden of adverse events (AEs) and can generate useful information on risk factors of AEs for more effective medicine use, especially in conjunction with introduction of new medicines and/or changes in treatment guidelines. This project aimed to implement an active surveillance pilot program for first-line antiretroviral therapy (ART) at sentinel sites in Namibia. METHODS Sentinel sites were outpatient ART clinics at the Windhoek Central Hospital and Katutura Intermediate Hospital. An active surveillance data collection form was developed and placed into patient charts. HIV+ adults naïve to ART were enrolled. Physicians recorded ART and health information during each follow-up visit, including presence or absence of AEs. RESULTS A total of 413 patients were included from August 2012 to April 2013. Average age was 37 years; 51% of patients were at WHO clinical stage 1; and mean baseline CD4 count was 216. The most common ART regimen was tenofovir/lamivudine/nevirapine. Presence or absence of AEs was recorded in active surveillance forms for 94% of first follow-up visits. In total, 66 patients experienced 119 AEs of any severity. Incidence of experiencing at least one AE was 33/100 person-years. Most common AEs were rash and abdominal pain. On active surveillance forms, demographic variables were missing in 14% of patients, and follow-up visits were recorded for 82% of patients. CONCLUSIONS Completeness of AE recording on active surveillance forms was high. With improved logistical considerations, such as incorporation of active surveillance forms into medical records, long-term active surveillance programs could be successful.

Abstract
Pharmacovigilance (PV) programs are an essential component of national healthcare systems. Well-functioning PV programs can improve population health by identifying and reducing medicines-related problems (MRPs). Many low- and middle-income countries lack functional PV systems, but this deficiency has not been described in terms of the potential economic value of strengthening PV systems. The assessment of economic value for PV can support rational decision making at the country level. We propose a framework for assessing the economic value of PV. We divide national PV systems into four levels: (1) no PV, (2) basic PV, (3) semi-functional PV, and (4) functional PV. These categories represent increasing levels of investment in PV capacity at the national or health facility level for all available medicines, including vaccines. The proposed framework can be used to estimate the costs of PV (including the value of investments to increase PV capacity and the costs of managing MRPs) and outcomes associated with PV (including improvements in morbidity, mortality, and quality of life as a result of the reduction in MRPs). The quantitative approach proposed for assessing costs and benefits uses a decision-analytic modeling framework that would estimate the value of the consequences of MRPs adjusted for their probability of occurrence. This allows the quantification of value using monetary outcomes (cost-benefit analysis), natural units (cost-effectiveness analysis), or mortality adjusted for quality of life or disability (cost-utility analysis). Evidence generated using this framework could assist policy makers, program managers, and donors in evaluating investments that aim to increase the capacity and efficiency of national and facility-level PV programs in low- and middle-income countries.
