Hospital lawsuits for unpaid medical bills in Wisconsin rose 37% from 2001-2018. These legal actions disproportionately targeted Black patients and those in poorer, less populated areas.
Area of Science:
- Health Law
- Public Health
- Healthcare Economics
Background:
- Hospitals increasingly pursue legal action to recover patient debt.
- Understanding trends in medical debt litigation is crucial for patient advocacy and policy.
- Previous research has not fully detailed the scope and demographic impact of these lawsuits in Wisconsin.
Purpose of the Study:
- To analyze trends in Wisconsin hospital lawsuits for unpaid medical bills between 2001 and 2018.
- To identify demographic and geographic disparities in these litigation patterns.
- To assess the impact of these lawsuits on vulnerable patient populations.
Main Methods:
- Utilized Wisconsin court records from 2001-2018.
- Quantified the rate of hospital lawsuits per 1,000 residents annually.
- Analyzed lawsuit data for disparities based on patient race and county-level socioeconomic and demographic factors.
Main Results:
- A 37% increase in hospital lawsuits for unpaid medical bills was observed from 2001 to 2018.
- The rate of lawsuits rose from 1.12 to 1.53 per 1,000 residents.
- Lawsuits were disproportionately filed against Black patients and individuals residing in poorer, less densely populated counties.
Conclusions:
- Wisconsin hospitals have escalated their pursuit of unpaid medical bills through litigation.
- Significant racial and socioeconomic disparities exist in who is targeted by these lawsuits.
- Findings highlight potential inequities in healthcare access and financial burden on marginalized communities.
