More on Preventing HAI’s

 

 

Two recent studies done on specialized patient populations identified combinations of interventions that were able to reduce hospital-acquired infections (HAI’s) by over 50%. The first study utilized a bundle of evidence-based interventions in patients undergoing spine surgery (discectomy, decompression, spinal augmentation or spinal fusion) and found surgical site infections declined by 50% after implementation (Featherall 2016). Components of the “bundle” were:

    1. screening for Staphylococcus aureus nasal colonization and decolonization with mupirocin
    2. self-preparation bath with chlorhexidine gluconate
    3. self-preparation with chlorhexidine gluconate wipes
    4. storage optimization of operating room supplies
    5. preoperative antibiotic administration algorithm
    6. staff training on betadine scrub and paint
    7. intrawound vancomycin in instrumented cases
    8. postoperative early patient mobilization
    9. wound checks at 2 and 6 weeks postoperatively

 

The number needed to treat (NNT) to prevent one infection was 47 patients. In addition to the 50 percent decline in SSIs there was an $866 cost reduction per case.

 

The second study (Halperin 2016) involved ventilator patients in patients in neurointensive care units and found an HAI reduction of 53% over an 18 month period. The two main interventions were (1) reducing the number of intrahospital transports and (2) reducing the number of urinary catheters. The primary way intrahospital transports was reduced was by the introduction of a mobile CT scanner so that patient needing frequent brain imaging could have the imaging done in the neuro ICU rather than being transported to the CT suite. Reduction in urinary catheters was accomplished by daily assessment of the continued need for such catheters, plus staff re-education on insertion and maintenance techniques plus introducing a new Foley kit that simplified and standardized the sterile insertion process Ventilator-associated events decreased 48 %, Foley use decreased 46 %, CAUTIs decreased from 11 per 1000 catheter days to 6.2.

 

Given our multiple columns on adverse events occurring in the Radiology suite (see full list below but in particular see our October 22, 2013 Patient Safety Tip of the Week “How Safe Is Your Radiology Suite?”) we would be interested to see if the reduction in transports to Radiology also resulted in fewer overall adverse events of other types. That may well have been the case since they also found overall complication rate decreased 55 %, ICU length of stay decreased an average of 1.5 days, and risk-adjusted mortality decreased 11%.

 

Lastly, back to one of the most important interventions to reduce HAI’s: good hand hygiene. We often have difficulty convincing our healthcare workers (particularly our physicians) that better compliance with hand hygiene actually translates to fewer HAI’s. That is especially a problem where levels of compliance with hand hygiene are already relatively high. Well, a recent study in CDC’s Emerging Infectious Diseases journal should bolster your argument. Researchers from UNC Chapel Hill (Sickbert-Bennett 2016) found that taking a hand hygiene compliance rate of >80% to an even higher one at >95% resulted in a further significant reduction in HAI’s. The association between hand hygiene compliance and HAI showed a 10% improvement in hand hygiene was associated with a 6% reduction in overall HAI rate. The association between hand hygiene compliance and HA-CDI (healthcare associated C. diff infection) showed a 10% improvement in hand hygiene was associated with a 14% reduction in HA-CDI. No association was noted between hand hygiene compliance and MDRO infections. While the authors could not rule out a contribution from unknown confounders, there were no other specific infection prevention goals adopted during the study period.

 

Read the Sickbert-Bennett article for details on their successful interventions. But key features were that the focus for observation was simply on cleaning hands upon entering and leaving patient rooms and that all healthcare personnel (including physicians, advanced practice providers, nurses, nursing assistants, hospital unit coordinators, housekeeping, radiology, occupational/physical/recreational therapists, nutrition and food services staff, phlebotomists, and respiratory therapists) were asked to make observations and provide immediate feedback to each other.
