Official Title: Trial of Positive Deviance in Inpatient Wards to Reduce Hospital Infections

Brief Summary: Healthcare-associated infections (HAI) are a significant public health burden. Even with existence of recommendations on technical strategies to prevent these infections, there is a need for strategies to increase staff engagement within the local organizational and cultural context. Positive deviance is one such approach that engages people in improvement efforts. Positive Deviance is based on the observation that in every community there are certain individuals or groups whose uncommon behaviors and strategies enable them to find better solutions to problems than their peers, while having access to the same resources and facing similar or worse challenges. In the proposed study, the investigators plan to test the effectiveness of using positive deviance based horizontal infection prevention approach to achieve overall reduction of HAIs among hospital inpatients. The investigators hypothesized that a broad and horizontal approach to reduce opportunities for acquisition of nosocomial pathogens using PD will lead to greater reduction of HAI among hospital inpatients compared to standard-of-care infection control approach. The investigators objective was to test the investigators hypothesis and evaluate whether there is greater decline in rate of HAI in the experimental group of wards compared to the control group of wards.

Detailed Summary:

Objective: To evaluate whether positive deviance (PD) based horizontal infection prevention approach will result in a higher rate of decline in incidence density of patients with HAI (central line-associated bloodstream infection, healthcare-associated pneumonia, catheter-associated urinary tract infection, or Clostridium difficile infection) per 1000 patient days per month in the intervention wards compared to control wards.

Design: A cluster randomized controlled trial was conducted over a period of 24 months. Six medical wards were randomized and positive deviance intervention was randomly allocated to one of the two groups of three wards each. The baseline, intervention and follow-up periods were 6, 9 and 9 months respectively.

Setting: A public safety-net major teaching hospital in United States.

Participants: The ward staffs participated in the intervention.

Intervention: Key components of the intervention were invitation to participate voluntarily, open-ended dialogues with staff members to discover barriers and seek solutions to prevent HAI, discussion of outcomes, and encouragement to prioritize and implement the solutions generated. Staffs of all six wards were asked to voluntarily participate in a modified hospital survey of patient safety climate (HSOPSC) and a social network survey at 6, 15, and 24 months.

Statistical analysis: Statistical methods used were time series modeling, summary of frequencies, Chi-square or Fisher's exact for testing difference in proportions and t-test.

Current Primary Outcome: Number of HAI per 1000 patient-days per month. [ Time Frame: 24 Months ]

The primary study outcome is the incidence density of HAI [a composite of central line associated bloodstream infection (CLABSI), hospital-acquired pneumonia (HAP), catheter-associated urinary tract infection (CAUTI) and C.difficile infection (CDI)] per 1000 patient-days per month.


Original Primary Outcome: Same as current
