PEBB: 1/18/05Prepared by Aon Consulting6 Methodology Aon Statistical Report Examines 4 different chronic diseases: Asthma, Diabetes, Coronary Artery Disease (CAD), Congestive Heart Failure (CHF) Measures changes in disease prevalence, participation, utilization, & cost for PEBB members based on incurred claims data Prevalence based on agreed-upon definitions of each chronic disease (ICD, CPT, & NDC Codes) Participation based on member list provided by carriers Three types of utilization & cost analysis Level I – with & without disease Level II – participant vs. non-participants Clinical Measures – provided by carriers BD attach. 5

PEBB: 1/18/05Prepared by Aon Consulting7 Methodology Carrier Reported Clinical Measures Additional clinical measures reported separately by carriers from non-claims sources (e.g. chart notes). Data reported uses the criteria mutually agreed upon by both carriers as outlined in the 2003 CDM Report HEDIS* measures have been added as a benchmark where available Regence relies on claims system for reporting on clinical measures from administrative data and does not have access to lab results * The carrier reported values should not be compared to HEDIS values as the carriers do not have the HEDIS continuous enrollment requirement. This difference in methodology was agreed to by both carriers at the beginning of the reporting process. BD attach. 5

PEBB: 1/18/05Prepared by Aon Consulting12 Aon Statistical Findings Cost Findings 28% of total 2003 PEBB claims were for members with at least one of the four chronic disease (includes claims for non-disease related illness/injury) Average monthly claims for members (PMPM) with chronic disease was $570 – 4x higher than for those without chronic disease PMPM ranged from $493 for asthma to $2,039 for CHF Rate of increase in PMPM costs from 2002 to 2003 was 19% for members with chronic disease compared to a 5% increase for members without chronic disease BD attach. 5

PEBB: 1/18/05Prepared by Aon Consulting13 Aon Statistical Findings Utilization Findings Overall utilization continues to be higher for members with chronic disease verses members without chronic disease Changes in utilization rates for members with chronic disease are mixed; additional analysis will be conducted to explain the reasons. Increases in utilization may be the result of members receiving appropriate preventive procedures which is positive. Still too early to confirm trends due to anomalies during the reporting period –2002 consolidation of carriers and plan designs –Small numbers for PEBB’s chronic disease populations –Many members have co-morbidities that confound analysis BD attach. 5

PEBB: 1/18/05Prepared by Aon Consulting17 Participation Kaiser participation is 100% for all diseases Regence participation rates vary by disease: –Asthma: 56% –Diabetes: 74% –CAD: 27% –CHF: 34% Regence participation increased significantly for CAD and CHF as a result of substantial changes in the administration of its disease management programs. Participation in 2002 was 5% for each disease prior to the changes. Note: Regence only contacts members considered ‘suitable’ for enrollment in disease management. For participation based on Regence suitability refer to page 20 of the 2003 Report. BD attach. 5

PEBB: 1/18/05Prepared by Aon Consulting19 Carrier Reported Clinical Measures: Asthma Use of Appropriate Medications for Patients with Persistent Asthma KaiserRegenceHEDIS 75th Good care for asthmatics includes preventing flares of wheezing and shortness of breath which interfere with the patient’s functioning. Two types of medication are used to treat patients with asthma; one to prevent acute flares, and one to treat acute flares when they occur Clinical Goal: increase in the percentage of patients regularly using medications to prevent acute flares Note: HEDIS percentiles have been included for benchmarking only and should not be used as a comparator with the carrier reported values as the carriers do not have a continuous enrollment requirement. Compliance with Appropriate Labs & Exams Data for Regence is Not Available BD attach. 5

PEBB: 1/18/05Prepared by Aon Consulting20 Carrier Reported Clinical Measures: Asthma ER Visits per 1,000 Kaiser Regence HEDIS 75th Preventive treatment should reduce acute flares which cause the patient to seek emergency care Clinical Goal: a decrease in the number of ER visits by patients with asthma Utilization Results There is no HEDIS Equivalent BD attach. 5

PEBB: 1/18/05Prepared by Aon Consulting21 Carrier Reported Clinical Measures: Diabetes Mbrs (18-75 yrs old) who had HbA1c Test Mbrs who had Eye Exam Mbrs (18-75 yrs old) who had LDL-C Screening Mbrs Monitored for Diabetic Nephropathy KaiserRegenceHEDIS 75th Excellent care of diabetes includes good control of the blood sugar levels and of cardiac risk factors (coronary artery disease is the leading killer of diabetics) Early detection of eye or kidney disease can lead to interventions to prevent or delay the onset of blindness or kidney failure Clinical Goal: increase in percentage of members receiving appropriate screenings Note: HEDIS percentiles have been included for benchmarking only and should not be used as a comparator with the carrier reported values as the carriers do not have a continuous enrollment requirement. Compliance with Appropriate Labs & Exams BD attach. 5

PEBB: 1/18/05Prepared by Aon Consulting23 Carrier Reported Clinical Measures: Diabetes ER visits per 1,000 Hospitalization for Diabetes or Comorbidity as Any Diagnosis KaiserRegenceHEDIS 75th Proper care should result in a reduction in the number of hospital admissions and ER visits for members with diabetes Clinical Goal: decrease in the number of hospitalizations per 1,000 and ER visits per 1,000 for diabetics Utilization Results Hospitalization for Diabetes or Comorbidity as Primary Diagnosis There are no HEDIS Equivalents BD attach. 5

PEBB: 1/18/05Prepared by Aon Consulting24 Carrier Reported Clinical Measures: CAD Mbrs Receiving Beta Blocker following a Heart Attack (AMI) Mbrs who had LDL-C Screening following an Acute Coronary Event (AMI, CABG, PTCA) Mbrs Using Aspirin following an Acute Coronary Event (AMI, CABG, PTCA) KaiserRegenceHEDIS 75th The goal of managing CAD is to prevent further events (angina/chest pain or repeat heart attacks) by controlling all risk factors (high blood pressure, cholesterol, inactivity, tobacco use) Beta Blocker medications are the best drug treatment for preventing recurrent heart attacks Aspirin has the ability to reduce clot formation in the narrowed coronary arteries Clinical Goal: increase in percentage of members receiving beta blocker treatment, cholesterol screening, and aspirin use Note: HEDIS percentiles have been included for benchmarking only and should not be used as a comparator with the carrier reported values as the carriers do not have a continuous enrollment requirement. Compliance with Appropriate Labs & Exams There is no HEDIS Equivalent Regence does not have Access to Chart Notes BD attach. 5

PEBB: 1/18/05Prepared by Aon Consulting25 Carrier Reported Clinical Measures: CAD Of the Mbrs Screened for LDL-C, the % of those screened with LDL-C Controlled KaiserRegenceHEDIS 75th LDL cholesterol is the form of cholesterol circulating in the blood that can attach to the blood vessel wall and cause further damage/narrowing Good care will result in management of all cardiac risk factors including cholesterol levels Clinical Goal: an increase in the percent of members with LDL-C controlled Note: HEDIS percentiles have been included for benchmarking only and should not be used as a comparator with the carrier reported values as the carriers do not have a continuous enrollment requirement. Clinical Results Regence does not have Access to Lab Results Kaiser Data not Available in 2002 BD attach. 5

PEBB: 1/18/05Prepared by Aon Consulting26 Carrier Reported Clinical Measures: CAD Hospital Admits for Members Having a Coronary Event (AMI, CABG, PTCA) Kaiser RegenceHEDIS 75th Preventive treatment should reduce the number of hospital admissions for members with CAD Clinical Goal: a decrease in the number of hospital admits per 1,000 for members with CAD Utilization Results There is no HEDIS Equivalent BD attach. 5

PEBB: 1/18/05Prepared by Aon Consulting27 Carrier Reported Clinical Measures: CHF Hospital Days for CHF (per 1,000) Re-admissions within 90 days (per 1,000) KaiserRegenceHEDIS 75th There are two goals of treatment for CHF -Minimize patient care -After hospitalization, discharge in a stable condition so that patient is able to self-manage Appropriate diagnosis and care during hospitalization and appropriate management as an outpatient will reduce both the number of hospital admissions as well as the number of re-admissions Clinical Goal: decrease in both the number of hospital days and the number of re-admissions Utilization Results There are no HEDIS Equivalents BD attach. 5

PEBB: 1/18/05Prepared by Aon Consulting28 Carrier Reported Measures Clinical Measures - Findings Performance on appropriate screenings and exams generally improved in 2003 Utilization results are mixed; additional analysis will be conducted to explain the causes. For example, the increase in CAD hospitalizations may be due to increased use of PCTA’s which is positive. Both carriers scored below HEDIS 75 th percentile on some measures, however, comparisons with HEDIS are difficult to interpret given the small size of PEBB’s chronic disease populations and differences in methodology *HEDIS benchmark measures not directly comparable due to HEDIS continuous enrollment requirement BD attach. 5

PEBB: 1/18/05Prepared by Aon Consulting30 Summary There is clear evidence members with chronic disease experience higher cost and utilization than the population without chronic disease Performance on clinical measures generally improved in 2003 Still too early to evaluate the effectiveness of PEBB’s Chronic Disease Management Program on controlling costs - consistent with current industry knowledge as outlined in the recent Congressional Budget Office findings In the early stages of evaluation, performance on clinical measures is a better short-term indicator of the overall effectiveness Additional experience is needed to isolate the long-term effect of chronic disease management due to: –Anomalies in 2002 reporting year (consolidation of carriers/plan design) –Random variations possibly due to the small population being measured BD attach. 5

PEBB: 1/18/05Prepared by Aon Consulting31 Recommendations for Future Program Direction Continue to track prevalence, utilization, cost, and clinical measures over time Encourage carriers to demonstrate continuous improvement in program design, participation, and outcomes Align current programs with 2007 Vision Develop intervention strategies for other conditions prevalent in the PEBB population e.g., obesity and smoking cessation Develop metrics and opportunities for collaboration to address depression BD attach. 5
