Insights
Patients undergoing total joint arthroplasty (TJA) at an urban safety-net hospital have high comorbidity rates, with 96.9% having at least one condition. This highlights the need for improved risk stratification in healthcare payment systems for TJA patients.
Area of Science:
- Orthopedic Surgery
- Public Health
- Health Economics
Background:
- The joint arthroplasty (TJA) population often presents with significant comorbidities, increasing healthcare costs.
- This study focuses on an urban safety-net hospital serving a socioeconomically disadvantaged population.
- High comorbidity rates in TJA patients can lead to increased surgical risks and poorer outcomes.
Purpose of the Study:
- To analyze the prevalence and distribution of comorbid diseases in TJA patients at an urban safety-net hospital.
- To calculate and evaluate the Charlson Comorbidity Index (CCI) scores within this specific patient cohort.
- To determine if current risk stratification methods adequately account for the high comorbidity burden in this population.
Main Methods:
- Retrospective analysis of 3011 consecutive TJA patients between 2008 and 2023.
- Calculation of age-adjusted Charlson Comorbidity Index (CCI) using documented comorbidities.
- Descriptive statistical analysis to determine CCI score distribution and identify frequent conditions.
Main Results:
- Nearly all TJA patients (96.9%) had at least one comorbidity.
- The mean CCI score was 2.25 ± 1.50, with 89.07% scoring 1 or higher.
- Most frequent comorbidities included hypertension (69.01%), obesity (45.37%), diabetes (30.09%), and anemia (23.05%).
Conclusions:
- TJA patients at this urban safety-net hospital exhibit a high incidence of comorbidities.
- This population represents a unique, high-risk subset undergoing TJA, potentially increasing complication rates.
- Enhanced risk stratification within healthcare payment systems is crucial for accurately reflecting the needs of such patient groups.
Background:
The joint arthroplasty population has a high number of comorbidities at the time of surgery, which increases the cost of care per episode. The goal of this study was to analyze the distribution of comorbid diseases in patients who have undergone total joint arthroplasty at our institution, which serves the poorest congressional district in the United States. We hypothesized that patients in an urban safety-net hospital would have higher comorbidity rates and higher Charlson Comorbidity Indices and that this would suggest the need for improved risk stratification in payment systems.
Methods:
A retrospective analysis was conducted by reviewing consecutive patients who underwent total joint arthroplasty between 2008 and 2023 (N = 3011). Relevant comorbidities were used to calculate the age-adjusted Charlson Comorbidity Index. From this, we determined the score distribution and identified the most frequent conditions. Descriptive statistical analysis was conducted to determine the mean and variance.
Results:
Within the patient population concerning CCI scores, 10.93% of the patient population scored 0, 22.42% scored 1, 27.33% scored 2, 20.86% scored 3, 10.73% scored 4, and 7.74% scored 5 and above. The mean CCI score was 2.25 ± 1.50. The most frequently occurring comorbid conditions according to hospital criteria in this population were hypertension (N = 2078, 69.01%), obesity (N = 1366, 45.37%), diabetes (N = 906, 30.09%), and anemia (N = 694, 23.05%). A total of 19.10% of patients were current smokers. Of all TJA patients, 96.9% had at least 1 comorbidity.
Conclusion:
The major finding from this retrospective analysis revealed the presence of a high incidence of comorbidities in the our health system's total joint arthroplasty population. We confirmed that this closed urban population is a unique subset of at-risk individuals who are undergoing TJA, which may increase their complication rates. Consideration for proper risk stratification in communities like this need to be considered.
