Strategies to Decrease C diff
What is C diff?
C diff Clostridium difficile (C. difficile) is an anaerobic, spore forming bacteria spread through fecal oral transmission C. difficile infection (CDI) colonizes the large intestine and releases two toxins Causes a number of illnesses; diarrhea, colitis and sepsis. Transmission: contaminated environments and health care personnel hands Antimicrobial therapy most important risk factor for CDI infection longer courses multiple antibiotics Fluoroquinolones the risk. Other drug may disrupt colonic flora; gastric acid suppression*, chemotherapy Health Research & Educational Trust (2017). Clostridium difficile Infection Change Package: 2017 Update.

Gap Analysis
Tier 1: First Steps to Address C. diff. C. diff surveillance Appropriate & timely testing of suspect cases > 3 days HO, <3 day CO Appropriate testing Clinically significant diarrhea without other obvious causes. Use recommended stepwise testing method Antibiotic Stewardship Eliminate unnecessary antibiotic use Use antibiotics with lower risk for promoting CDI Contact Precautions; order at time of ordering C. diff. test Hand Hygiene Glove and Gown use Patient specific equipment and disinfection prior to use with others Effective and thorough cleaning and disinfection processes Effective Hand Hygiene Program Environmental Cleaning
Stewardship and CDI Testing Only test symptomatic patients >3 unformed stools per day within 1 to 2 days Lab should refuse formed stools test Asymptomatic colonization rates high (10%) Don t test if received laxatives within past 24 hrs Don t retest within 7 days/lab hard stop Discontinue test if not collected within 24 hrs Time of test = placement into contact precautions Timely recognition of symptoms Health Research & Educational Trust (2017).

CDI Testing Rapid diagnosis will lead to prompt treatment & implementation of contact precautions that can limit the spread of CDI in the environment of care Polymerase chain reaction (PCR) tests have a sensitivity of 90 percent or greater and a specificity of 95 percent or greater Some facilities use a two step approach as a method of detection: 1) the stool is first tested for GDH and toxins and 2) indeterminate results then undergo PCR analysis. CDI is a clinical Diagnosis; no test makes the diagnosis of CDI Health Research & Educational Trust (2017). Clostridium difficile Infection Change Package: 2017 Update. Chicago, IL: Health Research & Educational Trust. Accessed at www.hret hiin.org.
Antibiotic Stewardship Program that promotes appropriate selection, dose, route and duration of antimicrobial therapy Primary goal: optimize clinical outcomes while reducing unintended consequences of antimicrobial use Toxicity colonization of pathogenic organisms Antibiotic resistance Secondary goal: reduce health care costs associated with diseases such as CDI and antimicrobial resistance. Comprehensive programs both large & small hospitals shown in an microbial use between 22% 36% with annual savings of $200,000 to $900,000. Health Research & Educational Trust (2017). Clostridium difficile Infection Change Package: 2017 Update. Chicago, IL: Health Research & Educational Trust. Accessed at www.hret hiin.org.
Antibiotic Use: What s The Issue 30% to 50% of all antibiotic use is inappropriate Inappropriate use includes: Longer than necessary duration of therapy Treatment of nonbacterial diseases Treatment of contaminants or colonizers Meaningless duplicate therapy (e.g., treatment with multiple antibiotics targeting anaerobes simultaneously) Monitoring and analyzing antimicrobial use by disease, unit and practitioner can increase organizational knowledge of opportunities for stewardship Health Research & Educational Trust (2017). Clostridium difficile Infection Change Package: 2017 Update. Chicago, IL: Health Research & Educational Trust. Accessed at www.hret hiin.org.
Antibiotic Use Among 323 U.S. Hospitals Model estimates that 30% reduction in use of broad-spectrum antibiotics will result in a 26% reduction in CDI. Greatest Risk MMWR March 7, 2014 / 63(09);194 200
Receipt of antibiotics in prior patients was significantly associated with incident CDI in subsequent patients (log rank P <.01) This relationship remained unchanged after adjusting for other factors known to influence risk for CDI (receipt of antibiotics by the subsequent patient, prior patients developed CDI).
England s Experience Key Points Significant reduction in hospital quinolone use was associated with a near eradication of quinolone R C. difficile (67% resistance to 3%) Quinolone R strains did not re emerge after an increase in quinolone use Cephalosporin restriction and enhanced infection control was not responsible for the demonstrated reduction in CDI given lack of decrease in quinolone S C. difficile
Key Prevention Action Steps Monitor Healthcare Effectiveness Data and Information Set (HEDIS) performance measures on antibiotic utilization in pharyngitis, upper respiratory infections and acute bronchitis. Eliminate (1) Remove redundant unnecessary combination antibiotics antimicrobial from therapy Adopt formulary, guidelines (2) for restrict managing options CAP using for a duplicate shorter course Educate antibiotics prescribing and clinicians antibiotics about for appropriate special selection, use dose, circumstances, timing and duration (3) provide of treatment ongoing surveillance of Focus antibiotic efforts on use reducing by pharmacy, the use of and certain (4) antibiotic escalate classes to associated physician with leaders CDI, such as as necessary all cephalosporins, of clindamycin which leads and fluoroquinolones to improved accuracy of antibiotic use. Limiting the formulary and requiring pre authorization for certain antibiotics is a key strategy in reducing unnecessary use of antibiotics Health Research & Educational Trust (2017).

Hand Hygiene is the Single Most Important Factor in Preventing the Spread of Infection Jullian Desayes I, et al American Journal of Infection Control 45 (2017) 51 8
Guidelines for Hand Hygiene in Health Care Settings If hands are not visibly soiled, use an alcohol based hand rub 62% for routinely decontaminating hands in all other clinical situations (20 30 seconds) (II) When hands visibly soiled or exposure to potential spore forming organisms, wash with either a non antimicrobial or antimicrobial soap & water (40 60 seconds) (II). Can still use ABH in non outbreak C diff settings Do not use Triclosan containing soaps Use gloves with CDI Decontaminate hands after removing gloves Provide HCW with hand lotions & creams to minimize occurrence of irritant contact dermatitis Use multidimensional strategies to improve hand hygiene practice (IA) Do not wear artificial fingernails or extenders CDC.
