  1. Post-implementation study on appropriate GI prophylaxis in the Inpatient Setting David Nguyen 5/14/12

  2. Objective Side effects of PPI Indications for stress ulcer/GI prophylaxis Adverse effects of proton pump inhibitor

  3. GI / Stress ulcer • Pathophysiology • Impaired gastric mucosal protection from poor perfusion caused by intense physiologic stress • Hypersecretion of gastric acid • Complication • Overt GI bleeding: Usually shallow and from capillary bed • 1.5-8.5% in all ICU patients • Up to 15% if no GI prophylaxis • Perforation: Rare. < 1% in SICU patients • Treatment • PPI > H2 blocker > Sucralfate = antacid

  4. Potential side effects of PPI C diff-associated diseases (CDAD) Increased risk of community acquired and nosocomial pneumonia Prolonged hypergastrinemia Gastric atrophy Chronic hypochlohydria Increased risk of fractures Hypomagnesemia Iron and B12 malabsorption Interaction with Plavix

  5. GI prophylaxis in ICU Major risk (need at least 1) Minor risk (need > 2) Coagulopathy (INR > 1.5, Plt < 50K, or PTT > 2x normal) Mechanical ventilation > 48hrs GI ulceration or bleeding within the past year Traumatic brain or spinal cord injury Severe burn (>35% of the body surface area) Sepsis ICU stay > 1 week Occult GI bleeding > 6 days High dose glucocorticoid therapy (>250mg hydrocortisone or equiv.) Enteral feeding (on case basis)

  6. Result * There were 5-7 patients who were placed on PPI as outpatient without indications

  7. Result/Conclusion • 12 out of 50 (24%) admitted patients were placed on PPI inappropriately • If not counting the “continuation of home medication group”, the % of inappropriate rises to 34% • Total cost of inappropriate PPI orders: • $45/day • 10 cups of coffee • 4 drinks • 5-8 meals in cafeteria • $1,350/month • > 1/3 of resident monthly salaries

  8. Study Overview • Background: • Recent retrospective review of ED/clinic admissions showed ~ 24% of pt had inappropriate PPI ordered for GI prophylaxis. • As a result, informational posters and emails were sent out emphasizing the importance of appropriate PPI use • Escalating health care expenditures and • The need for thoughtfulness on the part of physicians to reduce costs while maintaining/enhancing quality of care. • Goal: follow-up review of appropriate PPI use for GI prophylaxis on the medicine ward teams.

  9. Study Overview • Retrospective study: chart review • Inclusion Criteria: • 52 ED/clinic admissions to medicine ward teams period 4/25 – 5/2/12 • Indications to order PPI: • Continuation of home medication • H/o GERD, gastritis, GI bleeding, or presenting symptoms concerning for above diseases • Exclusion: ICU admissions and transfers

  10. Results *One case where PPI initially ordered but discontinued following day

  11. Results/Conclusions • Before: 12 out of 50 or 24% • After: 3 out of 52 or 6% were ordered inappropriately • Residents are taking heed of the proper indications for GI prophylaxis with PPI and implementing into daily use • In 1 case, d/c’ed PPI the following day

  12. Future Direction • Provide appropriate reminders for the new residents and incoming interns. • Analyze ICU admissions, transfers from ICU and OSH • Look into “home medication” group and see if these patients need to be discharged on PPI
