Developing a Novel Surgical Care Access Score for Patients With Osteoarthritis Considering Total Knee Replacement
Authors' conclusion
We developed a novel TKR care access score that may enhance quality measures available to patients, providers, payers, and researchers.
Study context
- Population
- Census tracts in the contiguous United States; Total knee replacement (TKR) demand from CDC OA prevalence estimates, supply from TKRs per hospital (CMS MedPAR database)census tracts
- Outcome
- TKR care access score (2SFCA), categorized low, medium or high
Methodological detailstwo-step floating catchment area (2SFCA) method, nationwide analysis, 55-km radius around each census tract, sensitivity analysis with 42-minute driving distance
- Two-step floating catchment area (2SFCA) method
- Nationwide analysis
- 55-km radius around each census tract
- Sensitivity analysis with 42-minute driving distance
Main finding
As reported in the abstract
Access score category across census tracts
Low access score
51%
Medium access score
24%
High access score
25%
Observational data: associations, not effects.
Further findings
Spearman correlation between national (55-km) scores and 42-minute driving time scores
- Spearman correlation coefficient
- 0.75
- Subset of census tracts
