Insights

Facility dogs significantly reduced anxiety in young children undergoing echocardiograms. This intervention was well-received by families and staff, offering a promising approach to pediatric cardiac care.

Area of Science:

  • Pediatric Cardiology
  • Child Psychology
  • Animal-Assisted Interventions

Background:

  • Over 1 million children in the U.S. have heart conditions, requiring frequent medical care.
  • Minimizing the long-term impacts of repeated medical surveillance is crucial for pediatric patients.

Purpose of the Study:

  • To investigate the effect of facility dog intervention on anxiety in young children during outpatient echocardiograms.
  • To assess the relationship between facility dogs and children's emotional state during cardiac procedures.

Main Methods:

  • A quasi-experimental study involving 70 children (18 months to 8 years) undergoing echocardiograms.
  • Child anxiety was measured pre- and post-procedure using the modified Yale Preoperative Anxiety Scale.
  • Facility dog intervention included play, therapeutic conversation, touch, and emotional support.

Main Results:

  • Child anxiety levels were significantly lower after the procedure compared to before (p < .001).
  • Children with prior echocardiogram history showed higher pre-procedural anxiety (p = .015).
  • Caregivers (97.2%) and staff (87.9%) found the facility dog intervention helpful.

Conclusions:

  • Facility dog intervention effectively reduced anxiety in young children during outpatient echocardiography.
  • The intervention was positively perceived by families and staff, with no noted workflow disruptions.
  • Facility dog programs represent a promising and well-received innovation for vulnerable pediatric populations.
