BackgroundA value of vaccination framework for economic evaluation (EE) identified unique value concepts for the broad benefits vaccination provides to individuals, society, healthcare systems and national economies. The objectives of this paper were to work with experts in developed countries to objectively identify three priority concepts to extend current EE.MethodsThe previously developed classification of value concepts in vaccination distinguished 18 concepts, categorised as conventional payer and societal perspective concepts and novel broader societal concepts. Their inclusion in current EE guidelines was assessed. Experts identified eight criteria relevant to decision-making and measurement feasibility, which were weighted and used to score each concept. The relative ranking of concepts by importance and the gaps in guidelines were used to identify three priority concepts on which to focus immediate efforts to extend EE.ResultsThe EE guidelines review highlighted differences across countries and between guidelines and practice. Conventional payer perspective concepts (e.g., individual and societal health gains and medical costs) were generally included, while gaps were evident for conventional societal perspective concepts (e.g., family/caregiver health and economic gains). Few novel broader societal benefits were considered, and only in ad hoc cases. The top-three concepts for near-term consideration: macroeconomic gains (e.g., benefiting the economy, tourism), social equity and ethics (e.g., equal distribution of health outcomes, reduced health/financial equity gaps) and health systems strengthening, resilience and security (e.g., efficiency gains, reduced disruption, increased capacity).ConclusionsGaps, inconsistencies and limited assessment of vaccination value in EE can lead to differences in policy and vaccination access. The three priority concepts identified provide a feasible approach for capturing VoV more broadly in the near-term. Robust methods for measuring and valuing these concepts in future assessments will help strengthen the evidence used to inform decisions, improving access to vaccines that are demonstrably good value for money from society’s point of view. 相似文献

BackgroundThe continuing expansion of the pharmacist’s role necessitates continuous evaluation of current practice to identify strategies for improvements. The International Pharmaceutical Federation (FIP) has developed tools to support stakeholders in identifying development needs and planning advancement strategies. The aim of this research was to utilise the FIP Global Competency Framework, version 2 (GbCF v2), and FIP Development Goals (DGs) to evaluate competencies related to pharmacy practice in Saudi Arabia, and to understand the strategies needed to develop and improve the current practice.MethodsThe study involved four phases. Phase 1 involved translation of the FIP GbCF v2 into the Arabic language. Phase 2 was a consensus panel validation to establish the initial relevance of the competencies to current practice. Phase 3 included a national survey distributed to all registered pharmacists in Saudi Arabia. The final phase was conducted through mapping ‘not relevant’ competencies to FIP DGs to identify priorities.ResultsThe translation phase yielded a bilingual framework that could be utilized by pharmacists in Saudi Arabia. The initial validation phase identified 61 behavioral statements (from 124 in the GbCF v2) as ‘highly relevant’ or ‘relevant’ to pharmacy practice. Findings from the national survey identified a list of ‘not relevant’ competencies that could highlight gaps in current practice. The final mapping phase generated a list of three FIP DG priorities: DG5 (competency development), DG8 (working with others) and DG11 (impact and outcomes).ConclusionThe study indicated that competencies in the GbCF v2 were relevant to pharmacists practicing in the country. However, some competencies were perceived as ‘not relevant’ to current practice and these highlighted gaps in the current practice that need attention. Mapping ‘not relevant’ competencies to FIP DGs should be used as a starting point towards developing strategies, systems, and protocols to advance pharmacy practice in Saudi Arabia. 相似文献

PurposeTo assess clinical outcomes and patency after transjugular intrahepatic portosystemic shunt (TIPS) reduction for overshunting adverse events.Materials and MethodsThis multicenter, retrospective observational study included 33 patients (male-to-female ratio, 20:13; mean age, 59 years; mean Model for End-Stage Liver Disease [MELD] score, 15) who underwent TIPS reduction between 2007 and 2020. Procedure indications included medically refractory hepatic encephalopathy (HE) (85%), post-TIPS hepatic insufficiency (HI) (12%), and heart failure (3%). The measured outcomes included improvement in HE (classified using the West Haven system) and HI, patency of reduced TIPS, and transplant-free survival (TFS).ResultsTIPS reductions were successfully performed using parallel stent (94%) or other (6%) techniques at a median of 120 days after TIPS creation (HE, median, 164 days; HI, median, 5 days). The portosystemic pressure gradient increased from a mean of 10 to 17 mm Hg (P < .001). The overall HE rate after TIPS reduction was 54%; HE was persistent, improved, and resolved in 21%, 32%, and 46% cases, respectively. In patients with HI, the MELD score increased from a mean of 22 before TIPS to 34 after TIPS (P = .061), but without improvement (0%) in HI after TIPS reduction (mean MELD score, 30; P = .266). Recurrent ascites occurred in 14% of the patients. The median shunt patency was 961 days (95% confidence interval, 476–1,447). The 30-day, 6-month, 1-year, and 3-year shunt patency rates were 92%, 81%, 74%, and 37%, respectively. The median TFS was not reached. The 30-day, 6-month, 1-year, and 3-year survival rates were 97%, 90%, 81%, and 60%, respectively.ConclusionsAlthough TIPS reduction may be an effective and durable approach to treat post-TIPS medically refractory HE, shunt reduction may not achieve meaningful benefit for HI. 相似文献

Physician assistants (PAs) and nurse practitioners (NPs) have established themselves as key members of the healthcare team to supplement practicing physicians in patient care. PAs and NPs are collectively referred to as “advanced providers” (APs) and work not only in primary care but in general surgery and surgical subspecialties. Studies have addressed AP integration into the profession of medicine and have examined cost and efficacy of APs, attitudes about APs among residents, and educational impact of APs, but very little literature exists that describes a formalized approach to AP integration into a department of surgery, specifically with AP/resident integration. The purpose of this paper is to describe an initiative for developing an operational improvement model for APs working with residents on surgical inpatient services in a large academic health center. The model consists of four components and each component is described in detail from discovery state towards continuous improvement. Formal professional development opportunities for APs as well as appointing a Clinical Director for Surgical APs have positively impacted AP integration into the department of surgery. 相似文献
