Performance-based contracting for hospitals: a mixed methods analysis of impacts on patient outcomes, equity and efficiency in a middle income country

公共卫生部是黎巴嫩最大的住院保险公司，覆盖52%的公民，每年约有240 000人住院。典型的患者是那些无法负担医疗保险，失业或自营职业，年龄超过64岁，或患有慢性疾病（如糖尿病，高血压，癌症）的人。为提供这些服务，公共卫生部与135家公立和私立医院进行了联系。自2001年以来，卫生部支付给医院的补偿标准是根据医院认证程序的结果确定的。然而，过去几年来积累的证据表明，这不是管理公共卫生部与医院之间关系的有效方式。重要的是，卫生部对医院业绩的信息并不完善。2014年，公共卫生部开始从仅认证的合同制度过渡到基于绩效的合同制度，包括患者结局。本研究的主要目的是在公共卫生部和黎巴嫩的医院之间建立基于绩效的合同制度，并评估其对患者和卫生系统的影响。这种合同意味着卫生部将通过向每位病人支付更高的基本费率来奖励表现更好的医院。我们将调查哪些因素可能影响医院绩效以及医院如何应对这种干预措施。过去二十年来，卫生服务部门在PBC方面做了大量工作。然而，支持其对患者的益处和成本效益的证据呈现出喜忧参半的结果。其中一个主要原因是设计严谨的研究数量有限。最近来自英国和美国的证据也发现，减少再入院和死亡率等积极影响可能仅限于短期，并强调了PBC测量，背景和设计的重要性。在低/中等收入国家，证据仍然较为有限，但建设和平委员会有很大的希望，因为它有可能对健康结果产生更大的影响。然而，这也意味着它可能会产生更大的意外或负面后果，在设计时应非常谨慎，并密切监测影响。在我们的研究中，在患者层面，我们将研究患者因特定条件再次入院的变化，这可能表明治疗不足，医院获得性感染或其他原因。我们亦会按病人的年龄和是否患有慢性病，研究每间医院入院病人的比例，因为有些医院可能会“挑拣”病情较复杂的病人，而不接纳这些病人。我们还将制定一份患者满意度调查问卷，并使用它来衡量患者的满意度，这将是他们接受治疗的医院的代表。在卫生系统/医院一级，我们将研究不同服务的利用率和成本，以及每家医院收治的病例有多复杂（病例组合）。我们将比较实施PBC前后这些绩效指标的结果，并调查是否有任何变化。我们还将采访一批医院管理者，以了解医院如何应对PBC，以及他们可能做出的影响其绩效的变化，例如更好地应用临床指南，我们会积极透过不同渠道，包括制作知识转化材料，以及举办研讨会和政策研讨会等活动，与持份者和公众分享研究成果。圆桌会议所获得的知识将用于指导今后黎巴嫩建设和平委员会的发展以及中低收入国家的类似举措。

The Ministry of Public Health (MoPH) is the largest insurer for hospitalizations in Lebanon, covering 52% of citizens and about 240,000 hospital admissions annually. Typical patients are those who are unable to afford health insurance, are unemployed or self-employed, are older than 64 years, or have a chronic disease (e.g. diabetes, hypertension, cancer). To provide these services, the MoPH contacts with 135 public and private hospitals. Since 2001 the reimbursement rate paid to hospitals by the ministry was determined by the results of a hospital accreditation process. However, over the past several years evidence has accumulated that this was not an effective way to manage the relationship between the MoPH and hospitals. Importantly, the ministry has imperfect information on the performance of hospitals. In 2014 the MoPH began a transition away from the accreditation-only contracting system, and towards one based on performance, including patient outcomes.The main purpose of this research is to develop a performance-based contracting (PBC) system between the MoPH and hospitals in Lebanon, and evaluate its impact on patients and the health system. Such contracting means that the ministry would reward hospitals that perform better by paying them a higher base rate per patient. We will investigate what factors may affect hospital performance and how hospitals responded to this intervention.There has been much work on PBC in health services over the past two decades. However the evidence to support its benefit to patients and cost-effectiveness presents mixed results. One of the main reasons for this is the limited number of strongly designed studies. Recent evidence from England and the United States has also found that positive effects such as reduced readmissions and mortality may be limited to the short-term, and underlined the importance of PBC measurement, context and design. In low/middle-income countries (LMIC) evidence is still more limited, though PBC holds much promise as it may have larger impact on health outcomes given the potential to improve. However this also means it may have larger unintended or negative consequences, and should be designed with great care and close monitoring of impact.In designing PBC, it is important to determine how performance will be measured and how we would evaluate its impact. In our research, at the patient level we will look at changes in patient readmissions for specific conditions, which could indicate inadequate treatment, hospital-acquired infections, or other causes. We will also look at the proportion of patients admitted to each hospital in terms of their age and presence of chronic diseases, as some hospitals may 'cherry-pick' and avoid patients with more complex conditions. We will also develop a patient satisfaction questionnaire, and use it to measure the satisfaction of patients that would be representative of the hospital they were treated at. At the health system/hospital level we will look at the utilization and cost of different services, as well as how complex are the cases being admitted to each hospital (case-mix). We will compare the results for these performance indicators before and after implementation of PBC, and investigate any changes. We will also interview a sample of hospital managers to understand how hospitals responded to PBC and what changes they may have made to affect their performance, such as better application of clinical guidelines, increased training or incentives to the health workforce.We will actively share our research findings with stakeholders and the public through various channels including developing knowledge translation materials and events such as seminars and policy roundtables. The knowledge gained will be used to inform future PBC development in Lebanon and similar initiatives in LMICs.
