Animal-Assisted Visitation Program Chlorhexidine Trial
- Conditions
- Clostridium DifficilePseudomonas AeruginosaMethicillin-resistant Staphylococcus Aureus
- Interventions
- Registration Number
- NCT04171817
- Lead Sponsor
- Johns Hopkins Bloomberg School of Public Health
- Brief Summary
Hospital-based Animal-Assisted visitation programs are important complementary therapies, but concerns with infection control may challenge the sustainability of these programs. Pilot data suggest that a low-cost chlorhexidine-based intervention targeted to the dogs involved in the visitation programs holds high potential to prevent pathogen transmission during sessions. In this study, the following aims will be tested: 1) To identify program-related risk factors for acquisition of hospital-associated pathogens by pediatric patients during animal-assisted intervention (AAI) sessions during an initial run-in phase of no intervention; 2) To determine the effect of chlorhexidine (CHX)-based interventions on acquisition of hospital-associated pathogens and microbial communities by patients during AAI sessions via a multicenter randomized controlled trial; and 3) To determine whether the specific benefits achieved by the visitation program, i.e. reduction in blood pressure, heart rate and self-reported pain and anxiety, are impacted by the interventions.
- Detailed Description
Hospital-based Animal-Assisted visitation programs provide an important complementary treatment in holistic patient care and reduce patient stress, pain and anxiety. However, the risk of transmission of pathogens, such as methicillin-resistant Staphylococcus aureus, is a challenge to the sustainability of hospital-based Animal-Assisted visitation programs. Pilot data suggest that a low-cost chlorhexidine-based intervention targeted to the dogs involved in the visitation programs holds high potential to prevent pathogen transmission during sessions. Therefore, child participants will be enrolled who interact with 40 dogs over twelve sessions (four observational, eight where the dog is randomized to intervention or control) at two enrollment centers. The following aims will be tested: 1) To identify program-related risk factors for acquisition of hospital-associated pathogens by pediatric patients during animal-assisted intervention (AAI) sessions during an initial run-in phase of no intervention; 2) To determine the effect of chlorhexidine (CHX)-based interventions on acquisition of hospital-associated pathogens and microbial communities by patients during AAI sessions via a multicenter randomized controlled trial; and 3) To determine whether the specific benefits achieved by the visitation program, i.e. reduction in blood pressure, heart rate and self-reported pain and anxiety, are impacted by the interventions. If findings support the hypothesis that chlorhexidine interventions are effective to prevent pathogen transmission through a multicenter, parallel-arm randomized controlled trial and does not reduce Animal-Assisted visitation program benefits to the children or impact the welfare of the therapy dogs, then this will provide strong evidence on which to base recommendations for infection control guidelines for programs nationally.

Group Intervention Description CHX Intervention B Chlorhexidine Dog-handler teams will follow a modified protocol for infection control, with Treatment B first for four sessions, and cross-over to Treatment A for four sessions. Participants enrolled in the session will derive their Arm assignment from the dog-handler team with which they interact. Treatment B will consist of the same pre-session shampoo with a commercial veterinary chlorhexidine-based product (2-4% chlorhexidine), with a single wipe with a chlorhexidine-impregnated cloth (2-4% chlorhexidine) at arrival. This treatment will depend on the residual activity of chlorhexidine throughout the visit. CHX Intervention A Chlorhexidine Dog-handler teams will follow a modified protocol for infection control, with Treatment A first for four sessions, and cross-over to Treatment B for four sessions. Participants enrolled in the session will derive their Arm assignment from the dog-handler team with which they interact. Treatment A consists of a pre-session shampoo with a commercial veterinary chlorhexidine-based product (2-4% chlorhexidine) within 24 hours prior to the session, and wiping with a chlorhexidine-impregnated cloth (2-4% chlorhexidine) at arrival at the session and every 20 minutes during the session, or between participants if the flow of participants is structured in a way that allows this (such as visits from one room to the next to visit individual patients).
- Primary Outcome Measures
Name Time Method Child MRSA exposure Baseline through intervention completion, an average of 60 minutes MRSA exposure is defined as children who do not have detectable methicillin-resistant Staphylococcus aureus (MRSA) nasal carriage before the dog session who then have MRSA detection (MRSA nasal carriage) after the dog session.
- Secondary Outcome Measures
Name Time Method Child Pseudomonas aeruginosa exposure Baseline through intervention completion, an average of 60 minutes Pseudomonas aeruginosa exposure is defined as children who do not have detectable P. aeruginosa nasal carriage before the dog session who then have P. aeruginosa detection after the dog session.
Child and Dog Clostridium difficile prevalence Baseline to intervention completion, an average of 60 minutes Positivity of child and dog for C. difficile at a session
