Evidence-based Linkages of SDoH to Health Outcomes – Part 3

Association Between Social Determinants of Health and Acute Care Utilization Among Older Adults Enrolled in Medicare Advantage

By: Don Gerdts (don.gerdts@3aimstrategy.com), August 16, 2022

SUMMARY

A study titled, “Association Between Self-reported Health-Related Social Needs and Acute Care Utilization Among Older Adults Enrolled in Medicare Advantage” published in JAMA Health Forum found that certain social determinants of health were associated with statistically significantly higher rates of acute care utilization, which included >50% increases in avoidable hospital stays and emergency department visits.

In the population of over 56,000 Medicare Advantage beneficiaries, almost 50% reported one or more health-related social needs (HSRN).  The exposures evaluated included food insecurity, financial strain, loneliness, unreliable transportation, utility insecurity, housing insecurity, and poor housing quality. 

The results of the study show the following:

  1. Compared with beneficiaries without HRSNs, beneficiaries with an HRSN had a 53.3% higher rate of avoidable hospitalization.
  2. Financial strain (+26.5%) and unreliable transportation (+51.2%) were each independently associated with increased rates of hospital stays.
  3. Except for utility insecurity, all the listed exposures were independently associated with increased rates of ED visits.
  4. The social determinant with the largest association with increased hospital stays and ED visits was unreliable transportation.
  5. Financial strain (+0.4%) and unreliable transportation (+3.3%) were also marginally associated with increased 30-day readmission rates.

CONCLUSION

While these risk factors do not stand alone the study identifies the significant role of specific social exposures in determining the increased incidence of avoidable hospitalizations, ED visits and 30-day readmission rates.  These results negatively affect the Triple Aim of value-based care by increasing cost of care without improving quality or outcomes.

Understanding how different HRSNs relate to different health outcomes can inform targeted, evidence-based policies, investments, and innovations to address specific social determinants of health without “medicalizing” them.

TripleAim Strategy Advisors can help stakeholders in the healthcare ecosystem as a consultant or advisor to identify the most prevalent social determinants of health linked to health outcomes and develop strategies to address them in pursuit of improving equitable, value-based care.

Mapping Medicare Health Disparities by Population

CMS has created and maintains a new tool for mapping Medicare health disparities by population (MMD).

The MMD interactive tool contains health outcome measures for disease prevalence, costs, hospitalization for 60 specific chronic conditions, emergency department utilization, readmission rates, mortality, preventable hospitalizations, and preventive services.

Z Codes Can Help to Predict Health and Financial Risk for Value-Based Care

ICD-10-CM (International Classification of Diseases, Tenth Revision, Clinical Modification) contains over 70 Z codes (Diagnosis codes that start with Z) that capture SDoH. These Z codes identify problems related to education and literacy, employment, occupational hazards, housing and economic circumstances, and health care access. There are also Z codes related to the patient’s social environment and problems related to upbringing, one’s primary support group, and many psycho-social circumstances such as imprisonment and exposure to disasters.

SDOH data can be collected by any member of a patient’s health care team during any encounter. This includes providers, nurses, community health workers, and self-reporting individuals. This SDoH data are documented in the patient’s encounter record in the list of presented diagnoses. Providers and staff are then able to submit the appropriate SDoH Z code(s) into the claims billing and encounter reporting system, which begins the institutionalization of SDoH data for future use.

A New Public Health Emergency in Medicaid?

The Families First Coronavirus Response Act specifies that Medicaid beneficiaries must re-determine their eligibility once the federal public health emergency is declared to have ended.

While all people who lose their Medicaid coverage qualify to enroll in the federal ACA marketplace for 2023 coverage, HHS estimates that five to ten million people will lose eligibility or choose to forego coverage.

Medicare Advantage Plan Revenue Take Hits Over Lower Quality Ratings

CVS Health and Centene have reported projected 2024 earnings reductions of 5% due to year-over-year declines quality bonus payments from the Medicare Advantage Star Rating program. The declines were caused primarily by the expiry of the one-time changes to the rating system due to the COVID pandemic, which results in a sharp reduction in Centene and CVS members in plans with a 4+ Star-rating for 2023.

The downward shift in MA Star Ratings will present revenue headwinds and operational hurdles for Medicare Advantage health plans in 2024, as additional changes in the Medicare Advantage Star Ratings are implemented.

From SDoH Policy to Action – AmeriHealth Caritas Creates Social Determinants of Life® Strategy

Social determinants of health can contribute to health disparities and inequities when there are challenges with regard to the accessibility and availability of nutritious food, safe housing, reliable transportation, and quality health care. AmeriHealth Caritas is referring to SDoH as the Social Determinants of Life® (SDOL) and developing an entire strategy around addressing SDOL. AmeriHealth Caritas are implementing their SDOL strategy through screening for key social determinants of health and be creating a new company focused on addressing those needs.

Medicare Advantage improves Value-based Care compared to FFS Medicare

Medicare Advantage significantly outperformed FFS Medicare on each of the 16 clinical quality measures and four of the six patient experience measures. Now that total Medicare eligibility is approximately 60 million beneficiaries and enrollment in Medicare Advantage plans approaches 50% of all Medicare beneficiaries, these findings demonstrate the success of the Medicare Advantage increasing value-based care by increasing quality of the care delivered.
