Computational Phenotyping of Operational Context in Florida Skilled Nursing Facilities: A 2023 Analysis of Care Quality
This 2023 study of Florida skilled nursing facilities utilizes computational phenotyping to demonstrate that facilities in socioeconomically disadvantaged neighborhoods experience significantly higher infection rates and lower successful discharge rates, arguing for regulatory reforms that account for social determinants of health rather than applying uniform punitive measures.

In the United States, nursing homes that specialize in skilled care are judged by how well they keep patients safe and help them return to their own homes. Federal agencies measure these facilities on specific goals, such as how often patients are readmitted to the hospital, how much care costs, how many infections occur inside the facility, and how many people successfully go home after treatment. These measurements determine whether a facility receives financial rewards or penalties. However, a growing concern among experts is that these measurements do not fully account for where a facility is located. A nursing home in a wealthy neighborhood faces different challenges than one in a poor neighborhood, yet the rules for judging them often look the same. This study asks whether the social and economic conditions of a neighborhood—such as income levels, housing stability, and education—actually influence how well a nursing home performs, and whether current evaluation systems unfairly punish facilities that serve the most vulnerable communities.
To answer this, a researcher at Florida Atlantic University examined every skilled nursing facility operating in Florida during 2023. There were 696 such facilities in the state. The researcher combined data from two large public databases: one containing detailed performance scores for each nursing home, and another containing hundreds of statistics about the neighborhoods where these homes are located. Instead of looking at each factor one by one, the researcher used a computer method called machine learning to let the data group the facilities naturally. The computer looked at sixty-four different neighborhood characteristics, ranging from the percentage of residents who own their homes to the density of housing units, and sorted the 696 nursing homes into two distinct groups based on the environments they serve.
The analysis revealed two clear patterns. The first group, which included 524 facilities, was located in neighborhoods with higher incomes, more homeowners, and fewer residents living in poverty. The researcher labeled this group "Socioeconomically Advantaged." The second group, consisting of 172 facilities, was found in neighborhoods with lower incomes, higher rates of renting, and more residents relying on government assistance for basic needs. This group was labeled "Socioeconomically Disadvantaged." When the researcher mapped these groups across the state, a striking geographic pattern emerged. The disadvantaged facilities were heavily concentrated in the urban coastal corridors of Southeast Florida, particularly in Miami-Dade, Broward, and Palm Beach counties, as well as in central urban areas. In contrast, many suburban and rural counties had almost no facilities from the disadvantaged group.
The study then compared how these two groups performed on the federal quality metrics. The results showed a significant difference in two specific areas. Facilities in the disadvantaged neighborhoods had a higher rate of infections acquired within the facility, averaging 1.38 percentage points higher than their advantaged counterparts. They also had a lower rate of successfully discharging patients to home or community settings, with a gap of 9.314 percentage points. These differences were statistically significant, meaning they were unlikely to be due to random chance. However, the study found no significant difference between the two groups regarding how often patients were readmitted to the hospital or how much money was spent per patient. This suggests that while the neighborhood environment strongly influences infection control and the ability to send patients home, it does not necessarily change the likelihood of a patient needing to return to the hospital or the overall cost of their care.
The researcher also looked at who owned these facilities. The data showed that non-profit facilities consistently performed better than for-profit ones across all four metrics, including readmissions, costs, infections, and discharge success. Government-owned facilities also performed better than for-profit ones in terms of infection rates and discharge success. This indicates that ownership structure plays a major role in quality, perhaps even more so than the neighborhood environment in some cases.
The findings suggest that current federal evaluation systems may be too blunt. By not adjusting for the difficult conditions of the neighborhoods where disadvantaged facilities operate, the system might be penalizing them for factors outside their control, such as a lack of local resources or a patient population facing greater social challenges. The researcher argues that instead of simply punishing these facilities with financial cuts, policy should shift toward providing targeted support. This could include grants to help facilities in disadvantaged areas hire more infection prevention staff, improve workforce stability, and receive extra funding to offset the structural disadvantages of their location. The goal is to create a system that recognizes the reality of the environment in which these facilities operate, ensuring that quality assessments are fair and that support reaches the places that need it most. Ultimately, the study concludes that every community matters, and understanding the specific context of a nursing home is essential for improving care for all patients.
