Financial incentives may increase performance on targeted activities and have unintended consequences for untargeted activities. An innovative pay-for-performance scheme was introduced for UK general practices in 2004. It incentivised particular quality indicators for targeted groups of patients. We estimate the intended and unintended consequences of this Quality and Outcomes Framework (QOF) using dynamic panel probit models estimated on individual patient records from 315 general practices over the period 2000/1-2005/6. We focus on annual rates of recording of blood pressure, smoking status, cholesterol, body mass index and alcohol consumption. The recording of each risk factor is designated as incentivised or unincentivised for each individual based on whether they have one of the diseases targeted by the QOF. The effect on incentivised factors was substantially larger on the targeted patient groups (+19.9 percentage points) than on the untargeted groups (+5.3 percentage points). There was no obvious evidence of effort diversion but there was evidence of substantial positive spillovers (+10.9 percentage points) onto unincentivised factors for the targeted groups. Moreover, provider responses were larger on those indicators for which more stringent standards were set and greater rewards offered. We conclude that the incentives induced providers to improve targeted quality and make investments in quality that extended beyond the scheme. We estimate that the average provider was paid pound20 500 for recording 410 additional items of information on the risk factors targeted by the financial incentives. Allowance for the positive spillovers reduces the estimated average reward from pound50 to pound25 per additional record.
经济激励措施可能会提高针对特定活动的绩效,并且会对非特定活动产生意外后果。2004 年,英国的普通诊所引入了一种创新的按绩效付费计划。该计划针对特定患者群体的特定质量指标提供激励。我们使用基于 2000/1 年至 2005/6 年期间 315 家普通诊所的个体患者记录的动态面板概率模型,估计了这种质量和结果框架(QOF)的预期和意外后果。我们关注的是每年记录血压、吸烟状况、胆固醇、体重指数和饮酒量的比率。根据 QOF 针对的疾病,每个风险因素的记录对于每个个体来说都是激励性的或非激励性的。对于目标患者群体,激励因素的影响明显大于非目标群体(+19.9 个百分点)。虽然没有明显的努力转移迹象,但有证据表明,目标群体的非激励因素存在大量积极溢出效应(+10.9 个百分点)。此外,对于设定更严格标准和提供更大奖励的指标,提供者的反应更大。我们的结论是,激励措施促使提供者提高目标质量,并对超出计划的质量进行投资。我们估计,每个提供者因记录财务激励措施所针对的风险因素的 410 项额外信息而获得了 20500 英镑的报酬。考虑到积极溢出效应,估计每个额外记录的平均奖励从 50 英镑减少到 25 英镑。
