2020 J Eval Clin Practhttps://www.doi.org/10.1111/jep.13365 caregivers, children, doctor shopping, drug abuse, health care utilization, physician switching, second opinion patients,
OBJECTIVES: Doctor shopping, double doctoring, and overlapping prescriptions are often used as synonyms for multiple physician appointments in the same disease episode. Such behaviours translate into poor patient satisfaction and patient-doctor communication as well as abuse or misuse of drugs, increasing health care costs and resulting in negative health consequences. This systematic review of the literature was conducted to identify factors that drive doctor-shopping behaviour in children’s caregivers. METHODS: The search was conducted in PubMed and grey literature and was based on the following search terms: included doctor or physician shopping, drug seeking, double doctoring, children, and combinations of those. Overall, 500 records were identified, of which 11 were selected for qualitative synthesis. Data extracted considered definitions of doctor shopping, co-morbidities, and target population characteristics. RESULTS: Definitions of doctor shopping were inconsistent. The frequency of doctor shopping was high for acute illnesses and ranged from 53% in children with a fever in Hong Kong to 18% at an emergency department in Canada. The incidence of this phenomenon was low when taking into account addictive drugs and was rated at 0.02% to 0.3% in the full paediatric population. This phenomenon was more prevalent in children younger than 1 year, in children with attention-deficit hyperactivity disorder (ADHD) and co-morbid psychiatric conditions, and in those whose caregivers themselves had psychiatric conditions. It was more frequent in cases with an acute disease (eg, fever, gastroenteritis, and urinary tract infection) than a chronic disease (eg, asthma). CONCLUSIONS: The knowledge about doctor shopping by children’s caregivers is limited, despite that this is a frequent behaviour. There is a need for further research covering a broader range of diseases. The causes and consequences of doctor shopping should be sought as well to investigate its relation to health care regulations and possibility to reduce unnecessary medical resource utilization.
Current state of developing advanced therapies for rare diseases in the European Union
2020 Expert Opinion on Orphan Drugshttps://www.doi.org/10.1080/21678707.2020.1835640
ABSTRACTObjective Advanced Therapy Medicinal Products (ATMPs) present significant therapeutic advantages for inherited rare diseases. However, the development of orphan ATMPs is challenging due to their complexity and unpredictable biological activity. This study aims to comprehensively describe the current state of orphan ATMPs in Europe.Methods Orphan drugs (ODs) granted by European Commission until March 2020 were investigated. The characteristic of diseases and ATMPs were extracted from the public summary reports of ODs from Committee for Orphan Medicinal Products. The methodology for the pivotal studies of ATMPs was extracted.Results A total of 274 ATMPs were identified, covering 116 rare diseases, with metabolic, optical, and oncologic diseases being the most targeted. A total of 158 ATMPs were indicated for life-threatening diseases, 129 ATMPs targeted diseases currently lacking authorized or satisfactory treatment available. Twenty-eight ATMPs are being investigated in the phase II/IIII or phase III studies. The median patient size of pivotal studies was 127, 15 were open-label studies, 8 were single-arm trials, and 14 reported surrogate outcomes.Conclusion There are rapid growths in developing ATMPs for life-threatening diseases with high unmet clinical needs. Optimizing the study methodology and exploring innovative design to facilitate the market access is paramount.
Epidemiological impact and cost-effectiveness of varicella vaccination strategies in the United Kingdom (UK)
2020 Clin Infect Dishttps://www.doi.org/10.1093/cid/ciaa1708 Cost-utility, United Kingdom, vaccination strategies, varicella,
BACKGROUND: Despite the burden of varicella, there is no universal varicella vaccination (UVV) programme in the United Kingdom (UK) due to concerns this could increase herpes zoster (HZ) incidence. This study assessed the cost-utility of a first-dose monovalent (V) or quadrivalent (MMRV) followed by a second-dose quadrivalent (MMRV) UVV programmes. GSK and MSD varicella-containing vaccines (VCVs) were considered. METHODS: A dynamic transmission and cost-effectiveness models were adapted to the UK. Outcomes measured included varicella and HZ incidences, the incremental cost-utility ratio (ICURs) over a lifetime horizon. The payer and societal perspectives were evaluated. RESULTS: The impact of V-MMRV and MMRV-MMRV UVV programmes on varicella incidence was comparable between both VCVs at equilibrium. HZ incidence increased by 1.6%-1.7% over seven years after UVV start, regardless of the strategies, then decreased by >95% at equilibrium. ICURs ranged from £5,665 (100 years) to £18,513 (20 years) per quality-adjusted life year (QALY) gained with V-MMRV; and from £9,220 to £27,101 per QALY gained with MMRV-MMRV (payer perspective). MMRV-MMRV was cost-effective in medium- and long-terms with GSK VCV, and only cost-effective at long-term with MSD VCV at £20,000 per QALY gained threshold. Without the exogenous boosting hypothesis, HZ incidence decreased through UVV implementation. ICURs were most sensitive to discount rates and MMRV price. CONCLUSIONS: A 2-dose UVV was demonstrated to be a cost-effective alternative to no vaccination. With comparable effectiveness as MSD VCV at lower costs, GSK VCV may offer higher value for money.
Real-world cost-effectiveness of rivaroxaban and apixaban vs VKA in stroke prevention in non-valvular atrial fibrillation in the UK
2020 Journal of Market Access & Health Policyhttps://www.doi.org/10.1080/20016689.2020.1782164 anticoagulants, atrial fibrillation, cost-effectiveness, economic, real-world evidence, stroke prevention,
ABSTRACT Background Morbidity and mortality associated with non-valvular atrial fibrillation (NVAF) imposes a substantial economic burden on the UK healthcare system. Objectives An existing Markov model was adapted to assess the real-world cost-effectiveness of rivaroxaban and apixaban, each compared with a vitamin K antagonist (VKA), for stroke prevention in patients with NVAF from the National Health Service (NHS) and personal and social services (PSS) perspective. Methods The model considered a cycle length of 3 months over a lifetime horizon. All inputs were drawn from real-world evidence (RWE): baseline patient characteristics, clinical event and persistence rates, treatment effect (meta-analysis of RWE studies), utility values and resource use. Deterministic and probabilistic sensitivity analyses were performed. Results The incremental cost per quality-adjusted life year was £14,437 for rivaroxaban, and £20,101 for apixaban, compared with VKA. The probabilities to be cost-effective compared with VKA were 90% and 81%, respectively for rivaroxaban and apixaban, considering a £20,000 threshold. In both comparisons, the results were most sensitive to clinical event rates. Conclusions These results suggest that rivaroxaban and apixaban are cost-effective vs VKA, based on RWE, considering a £20,000 threshold, from the NHS and PSS perspective in the UK for stroke prevention in patients with NVAF. This economic evaluation may provide valuable information for decision-makers, in a context where RWE is more accessible and its value more acknowledged.
Market access of gene therapies across Europe, USA, and Canada: challenges, trends, and solutions
2020 Drug Discovery Todayhttps://www.doi.org/https://doi.org/10.1016/j.drudis.2020.11.024 ATMP, gene therapy, cell therapy, marketing authorization, HTA, coverage, reimbursement,
A limited number of gene therapy medicinal products (GTMPs) have received marketing authorization (MA), of which some have been withdrawn, and even less have gained reimbursement. Many challenges that complicate GTMP market access can occur across multiple jurisdictions and decision-making contexts, but some reimbursement challenges are specific to jurisdictions. The importance of these challenges vary according to the specific therapy being developed, the country where market access is sought, and the efforts made by developers, regulators and payers to implement solutions to overcome these barriers. This review could alert developers to challenges associated with GTMP MA and how to address them.
Use of Patient Preference Information in Benefit-Risk Assessment, Health Technology Assessment, and Pricing and Reimbursement Decisions: A Systematic Literature Review of Attempts and Initiatives
2020 Front Med (Lausanne)https://www.doi.org/10.3389/fmed.2020.543046 benefit-risk assessment, decision-making, health technology assessment, patient preference, preference measurement,
Objectives: Inclusion of patient preference (PP) data in decision making has been largely discussed in recent years. Healthcare decision makers-regulatory and health technology assessment (HTA)-are more and more conscious of the need for a patient-centered approach to decide on optimal allocation of scarce money, time, and technological resources. This literature review aims to examine the use of and recommendations for the integration of PP in decision making. Methods: A literature search was conducted through PubMed/Medline in May 2019 to identify publications on PP studies used to inform benefit-risk assessments (BRAs) and HTAs and patient-centered projects and guidelines related to the inclusion of PPs in health policy decision making. After title and abstract screening and full-text review, selected publications were analyzed to retrieve data related to the collection, use, and/or submission of PPs informing BRA or HTA as well as attempts and initiatives in recommendations for PPs integration in decision-making processes. Results: Forty-nine articles were included: 24 attempts and pilot project discussions and 25 PP elicitation studies. Quantitative approaches, particularly discrete choice experiments, were the most used (24 quantitative elicitation studies and 1 qualitative study). The objective of assessing PPs was to prioritize outcome-specific information, to value important treatment characteristics, to provide patient-focused benefit-risk trade-offs, and to appraise the patients’ willingness to pay for new technologies. Moreover, attempts and pilot projects to integrate PPs in BRAs and HTAs were identified at the European level and across countries, but no clear recommendations have been issued yet. No less than seven public and/or private initiatives have been undertaken by governmental agencies and independent organizations to set guidance targeting improvement of patients’ involvement in decision making. Conclusion: Despite the initiatives undertaken, the pace of progress remains slow. The use of PPs remains poorly implemented, and evidence of proper use of these data in decision making is lacking. Guidelines and recommendations formalizing the purpose of collecting PPs, what methodology should be adopted and how, and who should be responsible for generating these data throughout the decision-making processes are needed to improve and empower integration of PPs in BRA and HTA.

INTRODUCTION: Currently, 15-20% of individuals with coronary artery disease (chronic coronary syndrome [CCS]) or peripheral artery disease (PAD) receiving routine treatment experience cardiovascular events (CVEs) within 3-4 years. Using PICOSTEPS (Patients-Intervention-Comparators-Outcomes-Setting-Time-Effects-Perspective-Sensitivity analysis) reporting, we evaluated the cost-effectiveness of recently approved rivaroxaban 2.5 mg twice daily in combination with acetylsalicylic acid 100 mg daily (RIV + ASA) for the prevention of CVEs among Finns with CCS or symptomatic PAD. METHODS: Myocardial infarction, ischemic stroke, intracranial hemorrhage, acute limb ischemia, amputations, major extracranial bleeding, venous thromboembolism, and cardiovascular deaths were modeled in a Markov model examining a cohort of patients with CCS or symptomatic PAD. Relative effects of the intervention (RIV + ASA) and comparator (ASA) were based on the COMPASS trial. The primary outcome was 3%/year discounted incremental cost-effectiveness ratio (ICER), defined as cost (2019 euros) per quality-adjusted life year (QALY) gained in the Finnish setting over a lifetime horizon. In addition to nonfatal and fatal CVEs, the effects factored Finnish non-CVE mortality, quality of life, and direct costs from a public payer perspective. Disaggregated costs and QALYs, costs per life year gained (LYG), and ischemic strokes avoided, net monetary benefit (NMB), expected value of perfect information (EVPI), economic value-added (EVA), cost-effectiveness table, and acceptability frontier were examined. Probabilistic and deterministic sensitivity analyses were conducted. RESULTS: In the deterministic comparison with ASA over a lifetime horizon, RIV + ASA resulted in a benefit of 0.404 QALYs and 0.474 LYGs for an additional cost of €3241, resulting in an ICER of €8031/QALY. The probabilistic ICER was €4313/QALY (EVPI €1829/patient). RIV + ASA had positive NMB (€8791/patient), low EVPI (€88/patient), high EVA (€8703/patient), and 91% probability of cost-effectiveness using the willingness-to-pay of €25,254/QALY. The primary result was conservative and robust for RIV + ASA. CONCLUSION: RIV + ASA was a cost-effective treatment alternative compared with ASA in patients with CCS or symptomatic PAD in Finland.
Finland lacks published evidence on the cost-effectiveness of approved interventions for the prevention of cardiovascular events among individuals with chronic coronary syndrome (stable coronary artery disease) or symptomatic peripheral artery disease at risk of cardiovascular complications. Rivaroxaban 2.5 mg twice daily plus acetylsalicylic acid 100 mg once daily is indicated and reimbursed in Finland for the prevention of cardiovascular events for patients with stable coronary artery disease or symptomatic peripheral artery disease. We assessed the effectiveness and costs of treatment with rivaroxaban plus acetylsalicylic acid in comparison with treatment with acetylsalicylic acid. That is, we examined whether rivaroxaban is cost-effective when prescribed in combination with acetylsalicylic acid.Cardiovascular events with their associated costs and impact on quality of life were modeled over the lifetime of patients. The main effectiveness outcome was quality-adjusted life years (modeled survival multiplied by the expected quality of life), and costs included those relevant to the Finnish public payer in 2019. Extensive sensitivity analyses were carried out to evaluate the impacts of different model inputs and rationale.Rivaroxaban plus acetylsalicylic acid had high probability of being cost-effective, compared with acetylsalicylic acid. By valuing quality-of-life benefit with a plausible willingness-to-pay, net cost savings of €8791 per patient could be gained or economic value added by €8703 per patient if rivaroxaban was used.

Chinese guidelines related to novel coronavirus pneumonia
2020 Journal of market access & health policyhttps://www.doi.org/10.1080/20016689.2020.1818446 Chinese Guidelines, covid-19, pharmaceutical Treatment,
Background and Objective: China has managed to control the coronavirus disease (COVID-19) with confinement measurements and treatment strategies, while other countries are struggling to contain the spread. This study discusses the guidelines related to COVID-19 in China in order to provide important references for other countries in the fight against COVID-19. Methods: Chinese guidelines relevant to COVID-19 were systematically searched via the China National Knowledge Infrastructure database, YiMaiTong database, and World Health Organization (WHO) COVID-19 database on March 20(th), 2020. Guideline information was extracted, including date of publication, source, objectives and the target population. Guidelines specific to the pharmacological treatment of COVID-19 were further investigated to identify the types of antivirus drugs recommended and to report on how treatment recommendations for COVID-19 have evolved overtime. Results: A total of 100 guidelines were identified, of which 74 were national guidelines and 26 were regional guidelines. The scope of included guidelines consisted of: the diagnosis and treatment of COVID-19, the management of hospital departments and specific diseases during the outbreak of COVID-19. Fifty-one of the included guidelines targeted overall COVID-19 patients, while the remaining guidelines concentrated on special patient populations (i.e. geriatric population, pediatric population, and pregnant population) or patients with coexisting diseases. Fifteen guidelines focused on the pharmacological treatments for all COVID-19 patients. Interferon, Lopinavir/Ritonavir, Ribavirin, Chloroquine, and Umifenovir represented the most recommended antivirus drugs. Among them, 7 Chinese guidelines have recommended Chloroquine Phosphate or Hydroxychloroquine for the treatment of COVID-19. Conclusions: China has generated a plethora of guidelines covering almost all aspects of COVID-19. Chloroquine, as one widely affordable treatment, was recommended by Chinese national guidelines and provincial guidelines. Considering the continuous debates around Chloroquine, confirmatory studies with robust methodology are awaited to address the unanswered questions on its potential benefits and risks on COVID-19.
Fidaxomicin compared with vancomycin and metronidazole for the treatment of Clostridioides (Clostridium) difficile infection: A network meta-analysis

We conducted a systematic review of the literature and network meta-analysis (NMA) to compare the relative effectiveness of antibiotic treatments for Clostridioides (Clostridium) difficile infection (CDI) including vancomycin (VCM), metronidazole (MTZ) and fidaxomicin (FDX). Eligible studies were randomised controlled trials (RCTs) including adults with any severity of CDI that was treated with VCM, MTZ or FDX. The NMA was performed using a Bayesian framework, using a fixed-effects model. The searches identified seven publications for inclusion, which provided five RCTs for VCM versus MTZ, and three RCTs for FDX versus VCM. The NMA showed that for clinical cure rate, there was no difference for FDX versus VCM, and there was a significant difference in favour of FDX versus MTZ (odds ratio [OR]: 1.77; 95% credible interval [CrI] 1.11, 2.83]). For recurrence rate, there was a significant difference in favour of FDX versus both VCM (OR: 0.50; 95% CrI: 0.37, 0.68) and MTZ (OR: 0.44; 95% CrI: 0.27, 0.72). For sustained cure (clinical cure without recurrence), there was a significant difference in favour of FDX versus VCM (OR: 1.61; 95% CrI: 1.27, 2.05) and MTZ (OR: 2.39; 95% CrI: 1.65, 3.47). These findings suggest that FDX and VCM are effective first-line treatments for mild or moderate CDI, whereas MTZ is not, and FDX may be more effective at preventing CDI recurrence than VCM.
