AI for outcomes-based compensation in healthcare
What is outcomes-based compensation in healthcare? Compensation plans in the healthcare industry have undergone a paradigm shift, with more providers moving away from volume-based to outcome-based compensation for their employees. This is partly attributable to the rising healthcare costs and enhanced patient empowerment, with a growing need for better quality of service delivery (Zigrang, 2022). Volume-based models compensate providers for the quantity of care delivered rather than the impact on the health status of patients (Tai et al, 2014). The vision for outcomes-based compensation in healthcare revolves around incentivizing and rewarding healthcare providers based on the outcomes they achieve in patient care rather than just on the volume of services delivered. This approach aims to improve the overall quality of care, enhance patient outcomes, and reduce healthcare costs. However, existing literature on outcomes-based compensation models shows mixed results in terms of impacts on quality of care and costs, with some reporting significant cost savings and others reporting increased costs of care, as expounded later on in this chapter. In an outcomes-based compensation model in healthcare, providers are encouraged to focus on delivering measurable results and positive patient experiences. This may involve achieving specific health outcomes, such as reducing hospital readmission rates, improving patient satisfaction scores, or effectively managing chronic conditions. By aligning compensation with outcomes, healthcare organizations aim to drive better patient outcomes, ensure patient safety, and enhance healthcare delivery. Healthcare outcomes reflect the quality of care offered by practice and remain stable over time compared to process measures, which keep changing over time. For instance, the target outcomes in a diabetic care clinic include reduced blindness, reduced amputation rates, improved self-management and confidence, and reduced heart attacks. These target outcomes that matter to patients the most tend to remain stable over time regardless of where you practice. On the other hand, process measures such as fundoscopic examination, blood glucose assessment, foot care, and medication review may vary over time. This forms one of the basis for outcomes-based compensation models (Dunbar-Rees, 2018). The outcomes-based compensation model offers several benefits to different players in the healthcare field. Patients get to enjoy quality care over volume, with the potential to address health inequalities. This is so because the model emphasizes outcomes that matter to patients, which tend to remain constant regardless of the geographical location. For instance, the target outcomes for a diabetic care clinic in Kisumu, Kenya, Africa, would be more or less the same as for a clinic in Atlanta, Georgia, USA. For the providers, outcomes-based compensation helps reduce the wastage of resources and unnecessary interventions by enabling efficient resource allocation. It also reduces fragmentation of care by encouraging collaboration and coordination across clinicians and specialties. The payers benefit through reduced wasted healthcare spend as well as focusing on buying healthcare that is based on outcomes that matter most to their beneficiaries (World Economic Forum, 2023). The outcomes-based model has been implemented across different healthcare facilities worldwide in a bid to improve the quality of care and reduce costs. There are several studies showing the impact of outcomes-based models on the quality of care, resource utilization, and healthcare costs. These studies show varied outcomes, with some reporting positive impacts and others reporting negative impacts or no significant impacts. For instance, the Pioneer Accountable Care Organizations (ACO) implemented by the Center for Medicare and Medicaid Services in the USA as an outcome-based compensation model reported a reduction in healthcare costs by approximately $385M in two years compared to the previous volume-based compensation model, with no difference in quality of care (McCarthy, 2015). The Medicare Shared Savings Program, which was also designed to incentivize cost reduction, reported similar cost savings of $385M dollars over one year of implementation (Eijkenaar & Schut, 2015). However, some studies suggest that outcomes-based models were associated with additional healthcare costs, mainly in the form of bonuses and incentives paid out to healthcare workers. For instance, the Quality and Outcomes Framework (QOF) implemented in the UK as a pay-for-performance program was reported to have spent about US $9 billion on incentive payments over a period of just seven years (Ryan et al, 2016). Outcomes-based compensation models impact on the quality of care delivered to patients, albeit to varying extents from the available literature. In one study, the Quality and Outcomes Framework model operationalized in the UK to incentivize family practitioners for target patient outcomes resulted in an increase in the median practices achieving the target HbA1C levels for diabetic patients from 59% to 66.7% in two years. (Vaghela et al, 2009). However, another study evaluating the impacts of the same Quality and Outcomes Framework in the UK on hypertension reported no significant change in blood pressure monitoring rates and treatment intensity attributable to the program. There was no significant difference in the cumulative incidence of stroke, renal failure, and heart failure as well (Serumaga et al, 2011). With such mixed data on the impacts of pay-for-performance on costs and outcomes, it is evident that this alone may not be sufficient to improve the quality of patient care, and more factors need to be accounted for in order to achieve optimal patient care quality. Another study in rural Kenya evaluated the utility of outcomes-based compensation models in improving the management of suspected malarial fevers. The program rewarded measures of process quality of care, including the proportion of patients correctly given antimalarial drugs based on test results. Incentives were provided to facilities with increased rates of treatment for confirmed malaria cases, as well as those with reduced treatment rates without any confirmatory tests. From the study, the odds of receiving treatment following a negative malaria test in the intervention arm was 0.15 relative to baseline, compared to 0.42 in the comparison facilities that were not enrolled in the program. This translated to a 2.75 times greater reduction of inappropriate prescription of antimalarial drugs in the incentivized groups compared to the comparison groups (Menya et al, 2015). Another instance in which the outcomes-based model has been utilized is through Humana’s
