Barrier nursing for c.diff patient what should you not do

Background: Clostridium difficile infection (CDI) is a critical patient safety issue. Consistent and regular performance of appropriate practices is effective in preventing CDI. Variation in adherence to these practices can impede their effective implementation and weaken CDI prevention.

Methods: Using the Systems Engineering Initiative for Patient Safety (SEIPS) framework we convened a focus group of 10 nurses to identify barriers and facilitators to compliance with a CDI prevention bundle that includes (1) prompt diagnostic testing, (2) empirical isolation for patients with suspected CDI, (3) consistent and appropriate contact isolation, (4) hand hygiene, and (5) disinfection of the patient room and objects in the room. On completion of transcript coding, analyses were performed based on bundle intervention and the work system element of the SEIPS model.

Results: A total of 58 excerpts were coded. Work system barriers or facilitators were associated with nearly every bundle intervention. The work system elements raised in over half of the excerpts were task (n = 31) (eg, amount of additional effort required to don and doff gloves and gowns) and organization (n = 30) (eg, recognition by all staff of the severity of CDI). Contact isolation was the most frequently discussed bundle intervention (n = 24).

Conclusions: The SEIPS systems engineering framework is useful to evaluate infection prevention practices for CDI and identify opportunities for improvement. Addressing the work system barriers and facilitators identified in this study is essential to effective implementation of infection prevention interventions, specifically for CDI.

Components of the C. difficile prevention bundle at the study institution

1. Enhanced contact precautions measures for patients with C. difficile infection (CDI)
Hospital Precautions
  • Rooming – patient placed in private room or with another patient with documented CDI infection

  • Signage – contact precautions posted on door, alcohol dispenser in/or assigned room covering dispense

  • Duration - Contact precautions should be initiated/maintained for entirety of admission or 90 days from the last positive test (whichever is longer). Patients readmitted to the hospital within 90 days should also be placed in contact isolation, and patients awaiting fecal microbiota transplant (FMT)

  • Accessibility – Personal protective equipment (PPE) should stocked and available in necessary sizes; room sink should be easily accessible for washing hands

Staff specific precautions
  • Hand hygiene before gloves – Use alcohol gel or soap and water prior to wearing gloves

  • Wash with soap and water before exiting– wash hands with soap and water after patient encounter

  • Disposable equipment – When possible, disposable equipment (including stethoscopes) should be used; otherwise all equipment must be cleaned with sporicidal agent

  • PPE wearing – Put on gowns and gloves prior to entering room and gown should be tied; PPE may be disposed in room once patient interaction complete and proper hand washing should occur thereafter

2. C. difficile diagnostic testing
When to test…
Adults
  • Patient with diarrhea (≥ 3 unformed stools* in the previous 24 hours), particularly those with risk factors, and no alternative etiology for diarrhea

  • Patients with IBD with flare symptoms

  • Hospital admitted patients within first 48 hours of admission with complaints of or any unexplained loose stools prior to admission

  • Patient treated for CDI with prior resolution of symptoms who may have new infection (i.e., symptomatic, diarrhea)

Pediatric
  • Patients ≥ 12 months with appropriate clinical findings (≥ 3 unformed stools* in the previous 24 hours), particularly those with risk factors and no alternative etiology for diarrhea

  • Hospital admitted patients > 3 years within first 48 hours of admission with complaints of or any unexplained loose stools prior to admission

  • Patient treated for CDI infection with resolution of symptoms who may have new infection

*Stool episodes should be measured as ≥ 3 unformed stools from patient’s baseline bowel movements per day
DO NOT test… (Applicable to adult and pediatric)
  • Patients < 12 months without appropriate clinical findings

  • Patients on laxatives

  • Any admitted patient age ≥ 3 years with < 3 unexpected liquid/loose stools after 48 hours of admission

  • A patient still taking oral vancomycin for CDI

  • Patients treated for CDI without complete resolution of symptoms with possible relapse

  • If patient had a C diff test result within last 7 days

  • Asymptomatic patients for nursing home placement

  • Patient near end of CDI treatment (i.e., testing for cure)

3. Environmental disinfection
  • Environmental Services perform room cleaning using bleach or peracetic acid (used daily and/or at discharge), and ultraviolet light disinfection (at discharge).

  • Adequacy of room cleaning assessed by direct observations of cleaning practices, microbiologic culturing of rooms before and after cleaning, or use of a fluorescent marker applied to surfaces before cleaning (the marker is checked after cleaning to see if it has been removed, which would indicate adequate cleaning).
