BackgroundThe economic impact of hip fractures on the health care system continues to rise with continued pressure to reduce unnecessary costs while maintaining quality patient care. This study aimed to analyze the trend in hospital charges and payments relative to surgeon charges and payments in a Medicare population for hip hemiarthroplasty and total hip arthroplasty (THA) for femoral neck fracture.MethodsThe 5% Medicare sample database was used to capture hospital and surgeon charges and payments related to 32,340 patients who underwent hemiarthroplasty and 4323 patients who underwent THA for femoral neck fractures between 2005 and 2014. Two values were calculated: (1) charge multiplier (CM, ratio of hospital to surgeon charges), and (2) payment multiplier (PM, ratio of hospital to surgeon payments). Year-to-year variation and regional trends in patient demographics, Charlson Comorbidity Index (CCI), length of stay (LOS), 90-day and 1-year mortality, CM, and PM were evaluated.ResultsHospital charges were significantly higher than surgeon charges and increased substantially for hemiarthroplasty (CM of 13.6 to 19.3, P < .0001) and THA (CM of 9.8 to 14.9, P = .0006). PM followed a similar trend for both hemiarthroplasty (14.9 to 20.2; P = .001) and THA (11.9 to 17.4; P < .0001). LOS decreased significantly for hemiarthroplasty (3.78 to 3.37d; P < .0001) despite increasing CCI (6.36 to 8.39; P = .018), whereas both LOS (3.71 to 3.79 days; P = .421) and CCI (5.34 to 7.08; P = .055) remained unchanged for THA.ConclusionHospital charges and payments relative to surgeon charges and payments have increased substantially for hemiarthroplasty and THA performed for femoral neck fractures.Copyright © 2020 Elsevier Inc.
