3. Objectives • Review the role of infection-related problems that lead to unnecessary admissions, readmissions, and avoidable complications • Discuss the cost from the fiscal and patient outcomes perspective • Illustrate the importance of the Infectious Diseases Physician – Hospital Partnership • Propose for consideration “The Infectious Diseases Service Line”

4. Case Study: 72 Year Old Diabetic Woman Emergency Dept. Hospital Nursing Home Day 0 Day 1 Day 2 Day 3 Day 4 Day 11 Day 12 Day 13 Day 14 Presents with fever and painful, red foot After 12 days in hospital, patient discharged to Nursing Home Treated with broad-spectrum antibiotics Fever not better, Abx changed • Antibiotic treatment stopped as gout was diagnosed. • Clostridium difficiletest ordered and treatment for this started. • Patient was isolated. • C difficilediagnosed. • ICUwith dilated colon – operating room for colon resection. Develops diarrhea ID Called

5. Case Analysis Emergency Dept. Hospital Nursing Home Day 0 Day 1 Day 2 Day 3 Day 4 Day 11 Day 12 Day 13 Day 14 Presents with fever and painful, red foot After 12 days in hospital, patient discharged to Nursing Home Treated with broad-spectrum antibiotics Fever not better, Abx changed • Antibiotic treatment stopped as gout was diagnosed. • Clostridium difficiletest ordered and treatment for this started. • Patient was isolated. • C difficilediagnosed. • ICUwith dilated colon – operating room for colon resection. • Potentially avoidable complication of antimicrobial therapy leading to lengthy stay • Numerous antibiotics – most of which not needed Develops diarrhea • Wrong initial diagnosis • Prolonged recovery including sub-acute stay ID Called • Late consultation with infectious disease

6. Key Take-Aways • Inappropriate diagnosis and treatment for infectious diseases is costly to the patient and system • Late consultation with ID specialist is costly

7. Some Basic Statistics Keep 3 things in mind: • Infections can happen anywhere • Infections can be costly • Antibiotic resistance is a problem so Stewardship and Infection Control are critical

8. Aggregate Costs Of Infectious Diseases • Clostridium difficile– nearly $9 Billion in annual costs Ref: Torio CM (AHRQ), Andrews RM (AHRQ).

11. Special Pathogens – Clostridiumdifficile • Clostridium difficile – Healthcare associated diarrhea infection related to antibiotic use • Adds an estimated $26,000 marginal cost per case to each hospitalized patient • Admissions nearly doubled from 2001-2010 - from 4.5 to 8.2 cases / 1000 admissions. • In 2009, C. diff accounted for a total of 336,000 admissions or 1% of all admissions • Estimated to have excess attributable costs of $1.3 billion Lucado, J.

13. ATA NATIONAL SUMMARY Estimated minimum number of illnesses and deaths caused by antibiotic resistance*: 2,049,442 Atleast illnesses, 23,000 *bacteria and fungus included in this report deaths Estimated minimum number of illnesses and death due to Clostridium difficile (C. difficile), a unique bacterial infection that, although not significantly resistant to the drugs used to treat it, is directly related to antibiotic use and resistance: 250,000 14,000 Atleast illnesses, W Ant mo to and deaths WHEREDOINFECTIONSHAPPEN? Antibiotic-resistant infections can happen anywhere. Data show that most happen in the general community; however, most deaths related to antibiotic resistance happen in healthcare settings, such as hospitals and nursing homes.

14. The Infectious Diseases Service Line Is A Solution • Antimicrobial Stewardship • Clinical Care • Infection Prevention • Microbiology Laboratory • Employee Health • Resource Management

15. Antibiotic Overuse Is Dangerous and Costly • Studies indicate that 30-50% of antibiotics prescribed in hospitals are unnecessary or inappropriate.  1.

17. Stewardship Creates Value

18. ID Specialists Improve Outcomes and Reduce Cost – Clinical Care Early ID Clinician Engagement for clinical care is critical to achieve the best outcomes

20. Improving Outcomes and Reducing Costs • Infection Prevention Intervention

21. Clostridium difficileat Rhode Island Hospital • Results of a 5 step program focused on reducing the incidence of Clostridium difficile • C difficileinfection control plan • Monitor morbidity and mortality of C. difficile • Improve test sensitivity • Enhance environmental cleaning • Standardize the treatment plan • Other interventions as necessary Mermel, LA et al, Reducing Clostridium difficile Incidence, Colectomies, and Mortality in the Hospital Setting: A Successful Multidisciplinary Approach. The Joint Com J 2013;39:298.

22. ID Clinicians Offer A Unique System and Population Orientation • Long-term focus of risk reduction and safety through system-wide infection prevention and control efforts • One of the few specialties that focuses on efficient resource management, across various sites-of-service • Effective managers of patient care transitions • Employing Outpatient Parenteral Antimicrobial Therapy (OPAT) • Extensivist activity in LTC • Strong competency towards  promoting team communication across all specialties and within the continuum of care

23. The Infectious Diseases Service Line Is the Solution Clinical Care ID Specialist-led Interventions Efficient Resource Utilization Early ID consults Infection Control & Prevention Judicious use of radiology services, micro/lab services Rescue ID Antimicrobial Stewardship Hazardous waste (“red bag”) management

24. Case Study – ID Rescue • 64 year old man has a total knee replacement. • Hospital has established TKR bundled payment agreement with payer • 2 weeks later the patient has fever and drainage from the knee incision. A diagnosis of infected joint is made. • Multiple treatment decision points, each with different cost implications Bundled Payment Hospital Payer Total Knee Replacement Option 1 – prolonged IV treatment and hope for the best $$ Option 2 – short course IV then long course oral treatment $$$ Option 3 – remove joint, IV treatment, replace joint $$$$$

25. There is a Better Way to Mitigate Risk Co-Management Agreement or Gain-sharing agreement with your ID Clinicians Link payment to Quality: • Metrics for acute care • Antibiotic utilization • Resistant organism prevalence • C. difficile rates • CLASBI, CAUTI, SSI • Metrics for population management • Readmissions • Vaccination rates Bundled Payment Hospital Payer Total Knee Replacement ID Services Clinical Care Efficient Resource Utilization ID Specialist-led Interventions Early ID consults Infection Control & Prevention Judicious use of Imaging/ Labs Rescue ID Antimicrobial Stewardship Hazardous waste management

26. Strategies to Limit Hospitalization and Cost Without Sacrificing Outcomes • Acute infection diagnosis • Acute infection medical service • Out patient – Alternate site care • Early ID Consultation • Rescue care • Readmission • Focused programs on septicemia, pneumonia, UTI and surgical wound disruptions at LTC

27. Case Study – Alternate Site Care • 54 yo man with fever for 2 weeks had blood cultures performed by his doctor. • He was seen by ID doctor because of long duration of fever. • Blood cultures positive for Streptococcus bacteremia. IV antibiotic treatment started as out-patient. • Workup and treatment for endocarditis complicated as outpatient • Total savings = $10,000 (Based on Millman and hospital per diem) • Patient Satisfaction = High • Risks = marked reduction for HAI ED/Hosp Option 1 – Send patient to ED $$$$$ PCP Outpatient ID Option 2 – OPAT and care $$ management under ID

28. The Infectious Diseases Service Line • Is a solution for • Quality • Cost • Outcomes VALUE

29. Final Key Messages Aligning incentives through gain sharing and co-management for the ID Service line provides a mechanism to achieve greater value

30. Final Key Messages • If you are not engaged with your ID consultants you are missing opportunities to reduce risk and add value • If your ID consultants are not engaged with you then you have the wrong consultants
