  1. Patient-centered Medical Home (PCMH)/Medical Home Port (MHP) Evaluation(with emphasis on chronic conditions, particularly diabetes) June 2012 Eric Christensen

  2. Overview • Context • MHS/Navy Medicine moving rapidly to PCMH/MHP models • Literature shows the potential of PCMHs, but success is not automatic • “78% of health spending is devoted to people with chronic conditions”* • Purpose • Assess the impact of the Bethesda PCMH on access, quality, and cost • Assess whether the MHP model is effective for different patient types and in different settings • Outcome • Resource allocation should consider the effectiveness of MHP model • Which populations to target first with MHP * Anderson and Horvath, “The Growing Burden of Chronic Disease in America,” Public Health Reports, 2004, 119(3):263-270

  3. Topics/outline • Results on access and quality • HEDIS metrics • Patient satisfaction survey • Results on use and costs • Overall • Chronic versus non-chronic patients • By chronic condition • Clinical Practice Guidelines (CPGs) adherence—diabetes • Note • Some slides use NNMC and others WRNMMC as some of the work was completed before the Bethesda-Walter Reed merger • Results in this brief are for the WRNMMC internal medicine MHP

  4. WRNMMC HEDIS scores (pre- and post-implementation) Note: The values for the pre-period are monthly averages for January-May 2008 compared to February-December 2009 for the post-period. The transition period was from June 2008 through January 2009.

  5. PCMH impact on access and patient satisfaction

  6. How to increase satisfaction and PCM rating? • Those reporting high levels of access and provider communication report high satisfaction and PCM rating • Access (OR: 2.1; CI: 1.4-3.2) • Provider communication (OR: 1.9; CI: 1.2-3.0) • Implies that increasing access and provider communication will increase satisfaction and PCM rating • But, how to do this? • Drivers of access • Ease of scheduling appointments (OR: 4.6; CI: 3.0-7.0) • Ability to get appt for routine care when needed (OR: 4.4; CI: 3.2-6.2) • Ability to get appt for urgent care when needed (OR: 3.7; CI: 2.5-5.5) • Drivers of provider communication • PCM listens carefully (OR: 13.5; CI: 6.4-28.4) • PCM provides complete and accurate info (OR: 12.9; CI: 5.2-31.9)

  7. Use and cost analysis • Conducted retrospective data analysis (FY07-10) • Transition period from June 2008 to January 2009 • Used differences-in-differences approach • Used two-step process for analyzing health care use and costs • Step 1: binary regression for user or non-user of a particular service • Step 2: OLS regression for amount of services for users only • Used NMC Portsmouth, NMC San Diego, and NHP Pensacola internal medicine clinics as comparison sites • Focused on chronic conditions • Diabetes, hypertension, hyperlipidemia, chronic obstructive pulmonary disease (COPD), coronary artery disease (CAD), and mental health

  8. PCMH impact on use – all enrollees

  9. PCMH impact on use – chronic patients

  10. PCMH impact on use – non-chronic patients

  11. PCMH impact on cost – all enrollees

  12. PCMH impact on cost – chronic patients

  13. PCMH impact on cost – non-chronic patients

  14. Cost impacts associated with chronic enrollees

  15. WRNMMC PCMH impact by condition *Model would not converge.

  16. Diabetes CPG metrics • Screening/exam • HbA1c exam (at least yearly) • Eye exam (every two years) • Lipid (LDL-C) screening (yearly) • Nephropathy (yearly) • Level/control • HbA1c control (> 9.0%) • Lipid control (LDL-C < 100 mg/dL) • Blood pressure control

  17. Diabetes CPG adherence rates—HbA1c exam

  18. Diabetes CPG adherence rates—eye care

  19. Diabetes CPG adherence rates—lipid control

  20. Diabetes CPG adherence rates—nephropathy

  21. Are changes in CPG adherence rates significant? • Controlling for demographic differences and other chronic conditions, PCMH patients are more likely to have yearly nephrology and lipid control panels than patients at control sites • HbA1c results are not meaningful because of the change in coding practice at WRNMMC in 2010 • Eye exams are recommended every two years, but with a 1-year comparison (2007 to 2010), there is a significant decline in patients receiving eye exams

  22. Staff survey – continuity and coordination of care • How often do you feel that you can exercise autonomy as opposed to having to utilize a standard procedure? • The question was only asked of providers

  23. Enrollment status of diabetics (Navy catchment areas)

  24. Chronic disease burden • “78% of health spending is devoted to people with chronic conditions. Quality medical care for people with chronic conditions requires a new orientation toward prevention of chronic disease and provision of ongoing care and care management to maintain health status and functioning.” • Health spending attributable to people with chronic conditions • 1 or more conditions: 88% for prescriptions, 72% for physician visits, 76% for inpatient • 2 or more conditions: 67% for prescriptions, 48% for physician visits, 56% for inpatient • Source: Anderson and Horvath, “The Growing Burden of Chronic Disease in America,” Public Health Reports, 2004, 119(3):263-270

  25. Pharmacy VariationUtilization and variation for maintenance and scheduled drugs Nevin Aragam, CNA Analysis and Solutions

  26. FOR OFFICIAL USE ONLY Outline • We investigate Navy pharmacy utilization and variation for FY 2011 to identify and understand patterns among our population of maintenance and scheduled pharmaceutical users • Methods • All drugs • Maintenance drugs • Scheduled drugs

  27. FOR OFFICIAL USE ONLY Methods • FY 2011 PDTS via MDR • Used catchment area of record to identify the eligible populations surrounding navy catchment regions • Identified all eligible beneficiaries in FY 2011 using DEERS and the demographic information from the most recent FM the beneficiary appeared • Maintenance drugs are identified with the MDR PDTS field Maintenance Drug = ‘Y’ • Scheduled drugs and identified using the MDR PDTS field DEA Class = 1, 2, 3, 4, or 5* * note, there were no drugs identified as having DEA class 1 in PDTS

  28. FOR OFFICIAL USE ONLY All pharmacy age distribution Age distribution for all pharmacy users
