Test Utilization in the Clinical Microbiology Lab What Works and What Doesn t Bobbi Pritt, M.D. Medical Director, Clinical Parasitology Laboratory Mayo Clinic, Rochester, Minnesota, U.S.A. 2016 MFMER 3281918-3 DISCLOSURES Relevant Financial Relationship(s) None Off-Label Usage None 2016 MFMER 3281918-4 2

Optimizing Test Utilization in Clinical Microbiology Similar challenges as other areas of the clinical laboratory Some unique considerations: Testing is dependent on numerous clinical factors Exposure history: Geographic location/travel Contact with infected individuals or animals Immune status (HIV/AIDS, HTLV-1, chemotherapy) Current outbreaks Presence of instrumentation (e.g. catheters, prosthetic joints) 2016 MFMER 3281918-5 Fecal Parasite testing as an example Complex testing options Traditional method for identification of parasites in feces is the Ova and Parasite examination (O&P) Appropriate for identifying many of the exotic parasites Less sensitive method for detecting the more common intestinal parasites in the United States (Giardia and Cryptosporidium) Requires up to 7 stool specimens for optimal detection of Giardia 2016 MFMER 3281918-6 3

Additional Detection Methods Antigen detection (Immunoassays) for Giardia and Cryptosporidium Multiplex PCR for bacterial, viral and parasitic pathogens Special staining methods: Modified acid fast stain for the coccidia Modified trichrome stain for microsporidia Individual PCR, culture and serologic tests 2016 MFMER 3281918-7 Too many options! Common approaches: Order all of the tests! Order the routine O&P that s what I learned in medical school I don t know what my patient has so I want the most inclusive test Preferred approach: Order of selective tests based on the clinical presentation and risk factors. Solution: An algorithm was developed based on published guidelines and clinician input 2016 MFMER 3281918-8 4

http://mayomedicallaboratories.com 2016 MFMER 3281918-9 A real-life experience The situation: the lab supervisor felt that the O&P was over-ordered and that physicians did not use our algorithm My approach: Step 1 examine the data 2016 MFMER 3281918-10 5

Stool Parasite Exam Test volumes 2005 2008 5000 4500 4000 3500 3000 2500 2000 1500 1000 500 0 Only <5% of our specimens were positive O&P Giardia EIA Cryptosporidium EIA Jan-05 Mar-05 May-05 Jul-05 Sep-05 Nov-05 Jan-06 Mar-06 May-06 Jul-06 Sep-06 Nov-06 Jan-07 Mar-07 May-07 Jul-07 Sep-07 Nov-07 Jan-08 Mar-08 May-08 Jul-08 Sept-08 Nov-08 Jan-09 Mar-09 May-09 2016 MFMER 3281918-11 A real-life experience continued Step 2 perform chart review Most O&P orders were incorrectly placed Patients were actually more likely to have Giardia or Cryptosporidium for which EIAs were recommended. Step 3 Talk to providers Most did not know that an algorithm was available for guiding orders Assessment The algorithm was not being used to guide O&P testing Plan Provide education 2016 MFMER 3281918-12 6

30 min Educational Video 60 min Educational Program Ongoing education To in-house physicians And residents O&P Educational Bulletin Giardia EIA Cryptosporidium EIA Mar 07 May-07 Jul-07 Sep-07 Nov-07 Jan-08 Mar-08 May-08 Jul-08 Sept-08 Nov-08 Jan-09 Mar-09 May-09 Jul-09 Sep-09 Nov-09 Jan-10 Mar-10 May-10 Jul-10 Sept-10 Nov-10 Jan-11 Mar-11 May-11 Jul-11 Sept-11 Nov-11 Jan-12 Mar-12 2016 MFMER 3281918-13 Conclusion Educational efforts are not enough to change ordering practices Why? Messages don t reach the right people Habit/patterns are hard to break Regular influx of new trainees and physicians 2016 MFMER 3281918-14 7

Can we turn this algorithm into a cascade? Cascade definition: a sequence of tests that are performed by the lab based on results of preceding tests. The cascade should be based on accepted guidelines and the components need to be transparent to providers. 2016 MFMER 3281918-15 2016 MFMER 3281918-16 8

Use of the Cascade Allows for efficient test ordering and significant cost savings Provider places an order for the algorithm Serum is drawn and sent to the laboratory ( send and hold ) The laboratory performs a cascade of tests based on the algorithm A la carte ordering is still available, but most clinicians choose to use the algorithm 2016 MFMER 3281918-17 Cost Comparison Comparison of Testing Options Celiac Disease Serology Cascade: Weighted Average Price $ 67.60 Total package if ordered a la carte $ 515.00 2010 Mayo Foundation for Medical Education and Research. All Rights Reserved. 2016 MFMER 3281918-18 9

Laboratory-Driven Algorithms Why this works: Only serum is required Initial limited laboratory testing drives additional testing Hence, the Laboratory has control over the algorithm rather than the Clinician 2016 MFMER 3281918-19 Can we turn this algorithm into a cascade? The most important question: can we get the information we need from our clinicians to guide testing? 2016 MFMER 3281918-20 10

Necessary information to determine if testing for intestinal parasites is even warranted 2016 MFMER 3281918-21 From a doctor s office: Stool specimen for Giardia antigen testing 2016 MFMER 3281918-22 11

Form for patients to complete: Have been in car for 1 hr 40 min 2016 MFMER 3281918-23 Challenges in implementing laboratorydriven cascades for intestinal parasites Initial AND sequential testing depends on clinical factors The laboratory has a difficult time getting this information Therefore, laboratory professionals have little control over testing Need to rely on the ordering clinician to use the algorithm 2016 MFMER 3281918-24 12

How do we get the ordering clinician to use the algorithm? 2016 MFMER 3281918-25 FINAL SOLUTION: Use the Ordering System 2016 MFMER 3281918-26 13

Use of the Test Ordering System Provides an opportunity to influence the provider at the point of order, usually before a specimen is obtained from the patient This is the best place to intervene! You can use the ordering system to: Provide education Collect information Make it easy to do the right thing and hard to do the wrong thing 2016 MFMER 3281918-27 Experience from our practice: We have noticed that tests at the top of the ordering screen get ordered more often than those at the bottom. Therefore, listing tests alphabetically may guide users to the first test they see (which might not be the correct one). A recommended approach: Put Common tests at the top of your order requisition or ordering screen. This is what we now do for all microbiology tests. 2016 MFMER 3281918-28 14

Conclusions Changing the order that tests appear is relatively simple method to achieve a modest change in ordering patterns. Consider: Have you seen your ordering screens? Do you know how your tests appear to your providers? How are your tests currently listed? Are the tests simply listed alphabetically or in a way designed to guide use? Can anyone order any test? 2016 MFMER 3281918-31 Options for Ordering System Interventions Low Complexity Removing tests Changing test names Moderate Complexity Changing the lay-out of the order screens/forms Adding helper text High Complexity Set up IT rules (Dr. Donato s inpatient test rules) Require information to be entered at the time of ordering 2016 MFMER 3281918-32 16

EXAMPLE: Ordering urine bacterial culture on patients with indwelling Foley catheter A reason must be checked for this order to be placed or the physician can t place the order. 2016 MFMER 3281918-33 A twist to the Ova and Parasite story Implementation of multiplex PCR tests for bacteria, viruses and parasites 2016 MFMER 3281918-34 17

GI Pathogens Panel Simultaneously tests for 22 pathogens Multiplex PCR Testing is performed in 1 hour Includes testing for: Giardia duodenalis Cryptosporidium spp. Cyclospora cayetanensis Entamoeba histolytica Expensive! 2016 MFMER 3281918-35 Special considerations Not all patients with diarrhea need testing How to guide provider ordering? Need to avoid duplicate testing for the same pathogens E.g. culture, EIA, individual PCR 2016 MFMER 3281918-36 18

How we accomplished this Created an algorithm with our ID partners Embedded the algorithm into the ordering system, along with helper text Embedded the algorithm into AskMayoExpert, a widely-used clinician support tool Created IT rules to prevent duplicate testing Also use manual cancellation in the lab for duplicates Education there s still a role! 2016 MFMER 3281918-37 Laboratory Testing for Infectious Causes of Diarrhea Community-acquired diarrhea, <7 days duration WITHOUT warning signs or risk factors for severe disease 1,2 Community-acquired diarrhea 7 days duration OR Travel-related diarrhea OR Diarrhea with warning signs/risk factors for severe disease 1 Health care-associated diarrhea (onset after the 3 rd inpatient day) or patients with recent antibiotic use Testing not generally indicated If diarrhea persists: GIP / Gastrointestinal Pathogen Panel, PCR, Feces 3 Consider OAP / Parasitic Examination if traveler with >2 weeks of symptoms 4 NEGATIVE POSITIVE CDFRP / Clostridium difficile Toxin Molecular Detection, PCR, Feces NEGATIVE If diarrhea persists: No additional testing required unless clinical picture indicates If diarrhea persists: Consider: STL / Enteric Pathogens Culture, Stool GIAR / Giardia Antigen, Feces LCMSP / Microsporidia species, Molecular Detection, PCR (immunocompromised patients) OAP / Parasitic Examination 4 Use clinical judgment to guide the need for additional testing. 1 Warning signs and risk factors for severe disease include fever, bloody diarrhea, dysentery, severe abdominal pain, dehydration, hospitalization, and immunocompromised state. 2 During the summer, consider ordering STFRP / Shiga toxin, Molecular detection, PCR, Feces on children with diarrhea even if they don t have frankly bloody diarrhea, are not toxic-appearing, and diarrhea has been present <7 days. 3 GI Pathogen Panel tests for common bacterial, viral and parasitic cases of diarrhea 4 Submit 3 stool collected on separate days for maximum sensitivity Note: in outbreak scenarios with a known organism, consider ordering a specific test for that organism (CYCL / Cyclospora Stain, CRYPS / Cryptosporidium Antigen, Feces, GIAR / Giardia Antigen, Feces, bacterial stool culture) Mayo Foundation for Medical Education and Research (MFMER), All rights reserved.

Additional Approaches (NOT STOOL!) 2016 MFMER 3281918-49 Use Residents and Fellows to control use of expensive molecular multiplex platforms Multiplex Respiratory PCR panel: Lab staff first confirm the medical service that ordered the test is one of the approved services Providers who are NOT on the approved list will receive a call from the Clinical Microbiology fellow Then a discussion about testing ensues, based on a script that we created 2016 MFMER 3281918-50 25

Script for ordering intervention The Clinical Microbiology lab received a nasopharyngeal swab collected from your patient, <patient name>, that included an order for the Multiplex Respiratory Pathogen PCR Panel. I just wanted to provide some information before we proceed with testing. First, I wanted to make sure you were aware that this test is very expensive and also tests for a number of viral pathogens for which there is no treatment available. Can you tell me a little bit about the patient s clinical presentation so that we can determine whether this is the right test? Based on the patient s clinical presentation, there may be some molecular alternative tests that may be more appropriate and cost effective (e.g. Influenza A/B PCR, RSV PCR) 2016 MFMER 3281918-51 Whatever approaches you use, be sure to capture your data Share data with lab and institutional leadership and attach dollar amounts (money saved, potential for savings) This is an excellent approach for getting the support you need to start and/or continue utilization efforts Gather pre- and post-intervention data You may find out that your intervention isn t working (time to try something new) Share ordering data with your clinicians This can be very powerful for identifying outliers clinicians who order far more tests than the others and getting them to change their practices 2016 MFMER 3281918-52 26

Summary There are many different approaches for tackling test utilization issues some with more impact than others. It is important to identify and partner with clinicianchampions Create and implement algorithms based on data and best practice The test ordering system can be a powerful tool to guide test usage. Don t aim for perfection any progress is good! Monitor your results and share successes with leadership 2016 MFMER 3281918-53 Thank you! 2016 MFMER 3281918-54 27
