The utility of PRO data on surgical volume: the example of carotid endarterectomy
Insights
Low surgical volume in carotid endarterectomy (CE) is linked to increased patient mortality and higher healthcare charges. This highlights the need for better hospital credentialing and quality initiatives.
Area of Science:
- Health Services Research
- Surgical Outcomes
- Healthcare Quality Improvement
Background:
- Variations in surgical procedures can impact patient outcomes and healthcare costs.
- Understanding surgical volume-performance relationships is crucial for quality assessment.
Purpose of the Study:
- To analyze variations in carotid endarterectomy (CE) surgical volume, mortality, readmissions, and charges.
- To explore the implications of these findings for healthcare providers and purchasers.
Main Methods:
- Review of Medicare claims data over a 26-month period.
- Small-area analysis to identify geographic and provider-level variations.
Main Results:
- A significant proportion of surgeons performed a low volume of CE procedures.
- Lower surgical volume was associated with higher mortality rates and increased healthcare charges.
Conclusions:
- Findings suggest a link between low CE surgical volume and adverse outcomes/higher costs.
- Highlights the importance of hospital credentialing and quality improvement initiatives like HCQII.
Abstract:
As part of a small-area analysis of carotid endarterectomy (CE) surgery, this review of Medicare claims data for a 26-month period addresses variations in surgical volume, mortality, readmissions, and charges. A surprisingly high percentage of surgeons performing CE did few procedures, and surgical volume appeared to be associated with higher mortality and charges. The implications of these data for both hospital credentialing committees and management and for purchasers and consumers of care, as well as the ways in which the Health Care Financing Organization's (HCFA) Health Care Quality Improvement Initiative (HCQII) will reorder their relationships with peer review organizations (PROs), are discussed. This study is useful in addressing the potential of efforts by PROs to increase the quality of care under the HCQII.
