10 Step III. Action Improve Antibiotic use for Urinary Tract Infections Modified CDC assessment of appropriateness of antibiotics for UTI form:

11 Step IV. Education- Medical Providers Small group sessions Presentation of facility antibiotic use, CDI and UTI review data Review appropriate testing and treatment of UTI Review antibiogram Review locally created treatment guidelines Provided pocket treatment cards Recommended Improvement of the documentation of signs and symptoms Clinical evaluation for every antibiotic prescription and at 48 hours, i.e. antibiotic time out

12 Case 1 An 86-year old male with a peripheral vascular disease (PVD) and chronic indwelling urinary catheter for urinary retention was admitted yesterday with a severe foot infection. Vascular surgery took him for a below-knee amputation last night. Post-op, no antibiotics were given. 12

13 Case 1, continued This morning, the vascular surgeon asks what antibiotics to give in response to the following urinalysis: Urine ph 5.00 Color Yellow Clarity Hazy Protein Trace Glucose Negative Bilirubin Negative Blood Esterase Nitrite RBC/HPF 4 WBC/HPF 97 Small Large Positive Bacteria 1+ Mucus Present 13

14 Question Case 1 Question 1 Case Summary Culture results are not back yet. How do you respond to this urinalysis? A. No antibiotics B. Nitrofurantoin C. Sulfamethoxazole/Trimet hoprim D. Ciprofloxacin E. Piperacillin/tazobactam 86 yo male with PVD and BPH for which he has a chronic urinary catheter. Post-op day 1 from below-knee amputation. Pre-operative UA shows + blood + leuk esterase - nitrites 1+ bacteria + mucous 14

15 Case 1 Polling Slide A. No antibiotics B. Nitrofurantoin C. Sulfamethoxazole/Trimethoprim D. Ciprofloxacin E. Piperacillin/tazobactam 15

16 Case 1 Answer A. No antibiotics. This is asymptomatic bacteriuria (ASB). Expect mild to moderate pyuria with ASB. Bacteria in the bladder leads to mild inflammation (so this is not quite the same as colonization but conceptually very similar). 16

Case 1 Follow-Up Questions Does this change if the patient does not have an indwelling urinary catheter? No. Up to ~20% of older men living in the community have asymptomatic bacturiuria.

17 Case 1 Follow-Up Questions Does this change if the patient does not have an indwelling urinary catheter? No. Up to ~20% of older men living in the community have asymptomatic bacturiuria. Should the patient s primary care provider recheck a urinalysis or urine culture as an outpatient? No. In the absence of symptoms, there is no reason to repeat a UA/culture to look for infection. 17

18 Case 2 An 83-year old male is admitted to the hospital with hypotension (92/58) and fever (100.3 F). He is too confused to answer questions. On exam, he resists pressure to his bladder and attempts to push your hand away. Janice Haney Carr Public Health Image Library His WBC is 4 with 64% neutrophils. His Creatinine is 2.3 (baseline 0.8). His chest film shows no acute changes. 18

19 Case 2, continued He is started on vancomycin and piperacillin/tazobactam for presumed urosepsis. His urinalysis shows: Janice Haney Carr Public Health Image Library Urine ph 5.50 Color Yellow Clarity Turbid Protein 100 Glucose Negative Bilirubin Negative Blood Small Esterase Large Nitrite Negative RBC/HPF 13 WBC/HPF 2312 Bacteria 3+ Mucus Present Hyaline Casts >20 19

20 Case 2, continued On hospital day 1, his Cr is 1.6. He is somulent and appears comfortable. The microbiology laboratory reports: >100,000 CFU/mL of Gram negative rods His vancomycin is stopped. He remains on piperacillin-tazobactam On hospital day 2, his Cr is 1.0. He is feeding himself breakfast. The microbiology laboratory reports: >100,000 CFU/mL of lactose fermenting Gram negative rods Janice Haney Carr Public Health Image Library 20

21 Case 2, continued On hospital day 3, his Cr is 0.9. He is sitting up on the side of the bed. The microbiology laboratory reports: >100,000 CFU/ML ESCHERICHIA COLI INTP AMPICILLIN S MCG/ML CEFAZOLIN S MCG/ML CIPROFLOXACIN S MCG/ML TRIMETH/SULFA S MCG/M NITROFURANTOIN S MCG/ML AMPICILLIN/SULB S MCG/ML Janice Haney Carr Public Health Image Library 21

22 Question Which antibiotic should we choose? Case 2 Question 1 Case Summary 83 yo male with urosepsis (fever, leukocytosis). Urine culture with Escherichia coli susceptible to: A. Ampicillin B. Cefazolin Ampicillin C. Ciprofloxacin Cefazolin Ciprofloxacin D. Sulfamethoxazole/Trimet Tmp/Sulfa hoprim Nitrofurantoin Ampicillin/ E. Nitrofurantoin Sulbactam F. Ampicillin/Sulbactam 22

23 Case 2 Polling Slide Which antibiotic should we choose? A. Ampicillin B. Cefazolin C. Ciprofloxacin D. Sulfamethoxazole/Trimethoprim E. Nitrofurantoin F. Ampicillin/Sulbactam 23

24 Case 2 Answer A. Ampicillin preferred B. Cefazolin preferred C. Ciprofloxacin (too broad) D. Sulfamethoxazole/ Trimethoprim ok if good renal function E. Nitrofurantoin ok if good renal function F. Ampicillin/Sulbactam (too broad) The idea is to narrow therapy. Janice Haney Carr Public Health Image Library 24

27 Case 2 Follow-Up Questions How long should he receive antibiotics? In patients with a catheter: 7 days if prompt symptom resolution days if a delayed response If no catheter. I favor 7 days if prompt symptom resolution Janice Haney Carr Public Health Image Library Please use calendar states to indicate stop dates (i.e. 9/26/2017). 27

Case 2, continued On hospital day 5, he is discharged. The next day, the microbiology laboratory reports a second bacterial species (in addition to the E.

32 Case 3, continued The nurse manager calls and want to know how to respond to the urine culture results. She assessed the resident before calling you and notes that she is at her baseline Together, you decide to stop the antibiotics. Public Health Image Library Case courtesy of Dr. C. Muehrcke

33 Case 3, continued You round at the nursing home and see the resident. She is asymptomatic and does not recall feeling sick. There is nothing in the chart to indicate any signs or symptoms of infection. She tells you exactly what happened on Saturday..

34 Case 3 Question 1 Question There are several possible interventions to reduce the changes of a similar event in the future. Where would you start? (No right/wrong answers just your opinion) A. Review protocols for collecting urine samples B. Educate staff about criteria for testing urine C. Educate families about risks of antibiotics D. Develop a protocol that includes non-antibiotic management of residents with concerns for UTI 34

35 Case 3 Polling Slide To reduce the risk of this happening again, where would you start? A. Review protocols for collecting urine samples B. Educate staff about criteria for testing urine C. Educate families about risks of antibiotics D. Develop a protocol that includes non-antibiotic management of residents with concerns for UTI 35

36 Clean Catch? Sit down Cleanse Cleanse again Hold labia apart Start to pee Stop peeing Position container Start to pee again and collect urine Put lid onto container without touching sides or lid Public Health Image Library

37 Specimen Handling Sample collected Saturday afternoon Sample received in the laboratory on Monday morning What happened in the meantime? Public Health Image Library

38 Recommendations for Urine Collection Suggest shower or bath before attempting clean catch. For men, short-term condom catheter. Check bag every 30 minutes. For women, in/out catheterization, unfortunately. If urinary catheter, then must change entire collection system before collecting sample. Samples must be stored in the refrigerator until transported to the lab. Public Health Image Library

39 Recommendations for Urine Collection Suggest shower or bath before attempting clean catch. For men, short-term condom catheter. Check bag every 30 minutes. For women, in/out catheterization, unfortunately. If urinary catheter, then must change entire collection system before collecting sample. Samples must be stored in the refrigerator until transported to the lab. Public Health Image Library We need to tell families, it s not just check a urine.

40 Establish Criteria for Testing Urine Diagnoses Urine Culture Clinical Symptoms Acute, uncomplicated urinary tract infection >100,000 bacteria, No more than 2 species of bacteria Dysuria OR Fever AND 1 of the following: -Frequency -Urgency -Suprapubic pain -Incontinence* -Gross Hematuria** Asymptomatic Bacteriuria >100,000 bacteria, No more than 2 species of bacteria No signs or symptoms referable to the urinary tract CDC/James Gathany Public Health Image Library Stone et al. Infec Control Hosp Epi 2012; *New or worsening of baseline incontinence **I have never known hematuria to a sign of infection in an older adult. Rather, it seems to indicate trauma to the mucosa, which can lead to urinary tract infection or urosepsis.

CID 2010: ( *I have never known hematuria to a sign of infection in an older adult. Rather, it seems to indicate trauma to the mucosa, which can lead to urinary tract infection or urosepsis.

43 2009 NHSN criteria for CAUTI Laboratory Urine culture with 10 5 cfu/ml of 1-2 bacterial species OR Urine culture with 10 3 and <10 5 cfu/ml, pyuria ( 10) and positive leukocyte esterase or postive nitrite Symptoms Fever (>38 C), suprapubic tenderness or CVA tenderness If catheter removed with 48 hours urgency, frequency, dysuria Janice NIAID Carr Public Health Image Library Leekha et al. ICHE Oct 2015 v36(10) *NHSN = National Healthcare Safety Network

44 Clinical & NHSN-defined CAUTIs are not always the same thing 85 patients in hospital met 2009 NHSN surveillance definition. All had a fever 42 (49%) with clinical CAUTI the patient was given a diagnosis and treated for UTI 46 (54%) with alternate source of fever (e.g., other infection, DVT) Janice Carr Public Health Image Library Leekha et al. ICHE Oct 2015 v36(10) *NHSN = National Healthcare Safety Network

49 Watchful Waiting This is an active process More frequent vital signs Oral hydration Assess for pain, changes in medicine, other reasons like a bad night s sleep or no stuffed cabbage CDC/James Gathany Public Health Image Library

50 Careful Observation Order Set Nace et al., JAMDA 2014;15:

51 Manage Family Members Set expectations with family members before the crisis

52 Potential Policies & Procedures NIAID Public Health Image Library Concerns about stinky or cloudy urine should lead to increased hydration and perhaps, watchful waiting/careful observation. Automatic review of all medication changes by outside providers. Send residents to the Emergency Room with a note clearly stating what you are (and are not) worried about.

Potential Policies & Procedures NIAID Public Health Image Library Clear criteria for collecting a urine sample Documented protocol for proper sample collection

53 Potential Policies & Procedures NIAID Public Health Image Library Clear criteria for collecting a urine sample Documented protocol for proper sample collection and handling Communication tools when nurses call a covering provider Proactively talk to residents and their family members on admission and during change of status

54 Take Home Messages A positive culture infection No tests of cure (Don t borrow trouble!) Asymptomatic bacteriuria (ASB) is common; expect pyuria Try watchful waiting/careful observation and hydration 7 days of antibiotics is usually plenty Public Health Image Library 54
