Potential Benefits to Participants
- Evaluation and improvement of data quality
- Evaluation of comparative performance as a guide to quality improvement
- Optional opportunity to explore value of enhanced coding of symptoms and clinical findings
Importance of Data Quality
- Distinction between conditions present on admission (comorbidities) and hospital-acquired complications will become increasingly important in quality assessment and in hospital reimbursement
- Underreporting or improper designation of hospital-acquired complications may result in distorted performance profiles and in financial penalties
Evaluation of Data Quality (1)
- Rates chronic conditions are not reported as POA
- Comparison of rates chronic conditions and associated combination codes are reported as POA
- Comparison of rates of reported hospital-acquired complications in high-risk patients discharged dead and discharged alive
Evaluation of Data Quality (2)
- Rates conditions reported as POA are associated with normal diagnostic admission laboratory data
- Rates cases with prolonged risk-adjusted lengths of stay do not have at least one reported hospital-acquired complication
Evaluation of Comparative Performance
- Evaluation of measured post-operative complication rates with and without validation using POA code and associated laboratory data
- Evaluation of hospitals comparative risks of death and post-operative complications and its risk-adjusted outcome rates with and without enhancement of its analytic database
Risk-Adjusted Mortality - CABG Surgery
Chart of risk-adjusted mortality in percent for CABG surgery
Chart shows confidence interval, predicted percent risk-adjusted mortality, observed percent risk-adjusted mortality, and p-value of predicted to observed percent risk-adjusted mortality for CABG surgery by hospital.
Chart does not include data values, so range of values are estimated.

Enhanced Coding of Clinical Findings
- Some ICD-9-CM codes for important symptoms and clinical findings often are underreported, in many cases because coding regulations preclude their use in conjunction with many diagnostic codes
- Examples are: coma (780.01), severe malnutrition (260, 261, 262), tachycardia (785.0), tachypnea (786.06), fever (780.6), hypotension (458.9), pleural effusion (511.9)
Collection of Supplementary Codes
- Permits evaluation of additional improvement in risk-adjustment of clinical outcomes
- Prepares facility for future enhancements to billing databases with revisions of coding standards and analytic practices
- Collection of supplementary codes is not required for participation in this project
