目的探讨如何将以资源为基础的相对价值比率(RBRVS)与关键绩效指标法(KPI)相结合,运用于公立医院绩效考核体系实践中。方法分析样本医院绩效考核体系的应用效果,根据医院总体目标,经过点值测算、指标选择,建立了一套具有医院特色的改良型RBRVS-KPI模式绩效考核体系。结果经实践,医疗质量和运行效率大幅度提高,在一定程度上促进了医院管理的精细化。结论RBRVS-KPI模式下的绩效考核体系较唯财务导向的绩效模式更能体现医护人员劳动价值,值得探索与推广。  相似文献

ObjectivesPain, a complex subjective experience, is common in care home residents. Despite advances in pain management, optimal pain control remains a challenge. In this updated systematic review, we examined effectiveness of interventions for treating chronic pain in care home residents.DesignA Cochrane-style systematic review and meta-analysis using PRISMA guidelines.Setting and ParticipantsRandomized and nonrandomized controlled trials and intervention studies included care home residents aged ≥60 years receiving interventions to reduce chronic pain.MethodsSix databases were searched to identify relevant studies. After duplicate removal, articles were screened by title and abstract. Full-text articles were reviewed and included if they implemented a pain management intervention and measured pain with a standardized quantitative pain scale. Meta-analyses calculated standardized mean differences (SMDs) using random-effect models. Risk of bias was assessed using the Cochrane Risk-of-Bias Tool 2.0.ResultsWe included 42 trials in the meta-analysis and described 13 more studies narratively. Studies included 26 nondrug alternative treatments, 8 education interventions, 7 system modifications, 3 nonanalgesic drug treatments, 2 analgesic treatments, and 9 combined interventions. Pooled results at trial completion revealed that, except for nonanalgesic drugs and health system modification interventions, all interventions were at least moderately effective in reducing pain. Analgesic treatments (SMD ?0.80; 95% CI ?1.47 to ?0.12; P = .02) showed the greatest treatment effect, followed by nondrug alternative treatments (SMD ?0.70; 95% CI ?0.95 to ?0.45; P < .001), combined interventions (SMD ?0.37; 95% CI ?0.60 to ?0.13; P = .002), and education interventions (SMD ?0.31; 95% CI ?0.48 to ?0.15; P < .001).Conclusions and ImplicationsOur findings suggest that analgesic drugs and nondrug alternative pain management strategies are the most effective in reducing pain among care home residents. Clinicians should also consider implementing nondrug alternative therapies in care homes, rather than relying solely on analgesic drug options.  相似文献

Intensive care is a specialist area of the hospital with concentration of resources and expertise to look after critically unwell patients. No set criteria exist for admission to intensive care, although patients usually have severe illness associated with physiological dysfunction and actual or impending organ failure. There are multiple scoring systems designed to assess severity of illness, all with significant limitations. The National Early Warning Score 2 (NEWS-2) is a commonly used ‘track and trigger’ system designed to detect and respond to the unwell or deteriorating patient. NEWS-2 is marker of physiological disturbance and high scores correlate with intensive care admission and mortality. Looking at the elective and emergency surgical population, patients at high risk of complications should be admitted to intensive care postoperatively. Increasing age, comorbidities, poor exercise tolerance and major surgical intervention are associated with adverse outcomes. Admission to intensive care often requires difficult time-critical decisions to be made with limited information. Intensive care admission can be the difference between life and death, but there are both physical and psychological harm associated with invasive organ support. The four pillars of medical ethics – autonomy, beneficence, non-maleficence and justice – can be used to guide these decisions.  相似文献

ObjectiveTo examine how plan premiums are associated with physician network breadth, hospital network breadth, and hospital network quality on the Affordable Care Act''s Health Insurance Marketplaces in all 50 states and the DC in 2016.Data SourcesData on plan premiums and characteristics came from 2016 Robert Wood Johnson Foundation Health Insurance Exchange (HIX) Compare. Provider network information was obtained from Vericred. Hospital characteristics were obtained from CMS Hospital Compare and the American Hospital Association (AHA) survey.Study DesignWe analyzed how plan premiums were associated with variations in physician network breadth, hospital network breadth, and hospital network quality using ordinary least square regressions with state‐rating area fixed effects and carrier fixed effects.Principal FindingsPlan premiums were positively associated with physician network breadth and hospital network breadth. We find the following statistically significant results: a one standard deviation increase in physician network breadth was linked to a premium increase of 2.8 percent or $101 per year; a one standard deviation increase in hospital network breadth was linked to a premium increase of 2.4 percent or $86 per year. There was no significant association between premiums and hospital network quality, as measured by hospital star ratings and the inclusion of teaching hospitals or the top‐20 hospitals nationwide.ConclusionsPhysician network breadth and hospital network breadth contributed positively to plan premiums. The roles of the two types of provider network breadth are quantitatively similar. Premiums appear to be insensitive to hospital network quality.  相似文献

ObjectivesTo inform how the VA should develop and implement network adequacy standards, we convened an expert panel to discuss Community Care Network (CCN) adequacy and how VA might implement network adequacy standards for community care.Data Sources/Study settingData were generated from expert panel ratings and from an audio‐recorded expert panel meeting conducted in Arlington, Virginia, in October 2017.Study DesignWe used a modified Delphi panel process involving one round of expert panel ratings provided by nine experts in network adequacy standards. Expert panel members received a list of network adequacy standard measures used in commercial and government market and were provided a rating form listing a total of 11 measures and characteristics to rate.Data Collection MethodsItems on the rating form were individually discussed during an expert panel meeting between the nine expert panel members and VA Office of Community Care leaders. Attendees addressed discordant views and generated revised or new standards accordingly. Recorded audio data were transcribed to facilitate thematic analysis regarding opportunities and challenges with implementing network adequacy standards in VA Community Care.Principal FindingsThe five highest ranked standards were network directories for Veterans, regular reporting of network adequacy data to VA, maximum wait time/distance standards, minimum ratio of providers to enrolled population, and qualitative assessments of network adequacy. During the expert panel discussion with VA Community Care leaders, opportunities and challenges implementing network adequacy standards were highlighted.ConclusionsOur expert panel shed light on priorities for network adequacy to be implemented under CCN contracts, such as developing comprehensive provider directories for Veterans to use when selecting community providers. Remaining questions focus on whether the VA could reasonably develop and implement network adequacy standards given current Congressional restraints on VA reimbursement to community providers.  相似文献
