1 2004 DxCG ®, Inc. -1- Rong Yi, Senior Research Associate, DxCG Inc. Academy Health Conference June 6, 2004 Better Provider Profiling: Adding Patient Risk Adjustment to Episodes

2 2004 DxCG ®, Inc. -2- Questions Keeping Us Up at Night: How much do patient comorbidities affect episode costs? Could we use the DCG Relative Risk Score that measures patient risk along with Medstats Episode Group method to more accurately determine expected costs? How do severity and risk-adjusted episodes change our provider profiling results? The credibility of a provider profiling initiative depends largely on how well we can respond to the my patients are sicker objection.

5 2004 DxCG ®, Inc. -5- Diagnosis Information Age/Sex DCG Model Clinical Categories Patient Risk Scores DxCGs DCG/HCC Models Developed using regression methods on Medstats MarketScan database (commercial model) Model input includes demographic information and all diagnosis information (and/or drug information) for a patient for a period (typically a year) Assigns a set of risk scores to the patient that measures current and future risk (used for adjustment in profiling and predictive modeling).

Average Episode Cost DCG Risk Score (Health Burden, 1.0 = Avg) Whole Patient Cost Next Year Risk-Adjusted Episode Cost 45 year old female Healthy $ $1,500?? 55 year old male Early Chronic $ $4,500?? 64 year old female Chronic with Complications $ $12,500??

10 2004 DxCG ®, Inc Stages are not comparable across MEGs, but broadly higher stages go with higher risk scores. Ordinal Stage# of EpisodesMean Patient Risk Score Range 0409,3171.3(0.1, 56.4) 1962,9462.1(0.1, 52.5) 273,8663.2(0.1, 52.5) 310,4915.1(0.1, 52.5) Overall Relationship between Episode Disease Stage and Patient Illness Burden

11 2004 DxCG ®, Inc Risk-Adjusted Episodes in Provider Profiling Problem: While episodes can be severity-adjusted, without adjusting for patient risk, there is the potential to unfairly reward physicians who care for patients with few co-morbid diseases and penalize those who effectively care for patients with significant disease burden. Proposed solution: Marry the patient-level risk scores from DxCG with the severity score within Medstats Episodes Grouper to fairly evaluate physicians and pay for the best performance. Medstats Episodes Grouper Severity-adjustment within Episode DxCGs HCC Model Whole-patient Relative Risk Score Risk-adjusted Episodes

12 2004 DxCG ®, Inc Developing the Risk-Adjusted Episode Model MarketScan database –Only complete episodes with enough time for claim run-out –20 million episodes in 2002 Regression models incorporating –MEG –Disease Stage –DCG/HCC Prospective Relative Risk Score Predict episode cost within each MEG

14 2004 DxCG ®, Inc Overview of BCBS of South Carolinas Profiling Efforts 1+ million enrolled members Provider Contracting deals with over 1600 physicians Profiling effort began in 1998, using the MEGs. Profile specialists with more than 100 members on episode cost and use information and compare to specialist norms

16 2004 DxCG ®, Inc Performance Ratios by Physician Performance ratios for most physicians (the ratio of actual $ / expected $) are similar between the two methods. Some physicians performance ratio changes significantly when we add patient risk to the adjustment. Physician H moved from an outlier to practicing within expected range Physician D is even more of an outlier Adjusted using episode group and stage Adjusted using episode group, stage and patient risk

19 2004 DxCG ®, Inc Conclusions Episode costs increase with the severity of the disease (MEG) and disease burden of the patient (RRS) Considerable variation in episode costs leaves room for risk adjustment Organizations can improve the accuracy of provider performance assessments using risk-adjusted episodes. This is important for ensuring equitable pay-for-performance. Plans are underway to incorporate risk-adjusted episodes into the Medstats standalone episode grouper and Advantage Suite.
