Background: Childhood obesity has become a public health crisis, straining the healthcare system. Top healthcare organizations have identified pediatric primary care providers as pivotal in treating and addressing childhood obesity. Objective: To determine if an interdisciplinary pediatric primary care-based motivational interviewing quality improvement program can improve provider outcomes in treating childhood obesity. Methods: Pediatric primary care providers in two rural clinics were trained in motivational interviewing directed at childhood obesity. All recruited providers received the intervention, and implementation took place over 12 weeks. A retrospective chart audit was conducted. Results: There was a post-implementation increase in providers’ confidence in using motivational interviewing, engaging in discussions, and obtaining patient and parent/caregiver buy-in. Most participants were satisfied with the program, likely to recommend it, and use motivational interviewing. Conclusions: The use of a motivational interviewing training program led to improvements in provider outcomes. The program was beneficial in addressing pediatric obesity and engaging in difficult conversations with patients and families. Implications for Nursing: Motivational interviewing can have tremendous positive health outcomes for pediatric patients. Offering training in motivational interviewing would prove beneficial to healthcare providers and patients.
