Insights
Optimizing prophylactic antibiotic timing in pediatric surgery improved administration rates from 38.6% to 94.0% using systems-based interventions. Surgical site infection rates remained stable.
Area of Science:
- Pediatric Surgery
- Infectious Disease Prevention
- Quality Improvement in Healthcare
Background:
- Prophylactic antibiotic administration is crucial for preventing surgical site infections.
- Suboptimal timing and delivery of antibiotics can reduce their efficacy.
- A large pediatric tertiary care center aimed to enhance antibiotic protocols.
Purpose of the Study:
- To optimize the timing and delivery of prophylactic antibiotics for all surgeries in pediatric patients.
- To improve adherence to recommended antibiotic administration guidelines.
- To assess the impact of interventions on antibiotic timing and surgical site infection rates.
Main Methods:
- A multidisciplinary team utilized the A3 problem-solving method for a quality improvement initiative (July 2015-December 2019).
- Interventions included guideline updates, electronic health record modifications, workflow optimization, and an operating room timer.
- Statistical process control was used to assess intervention effectiveness.
Main Results:
- Over 32,000 pediatric surgical cases were analyzed.
- Key barriers identified were delayed ordering and lack of operating room availability.
- Appropriate antibiotic timing improved significantly from 38.6% to 94.0% (P < .001).
- Surgical site infection rates remained stable throughout the study.
Conclusions:
- The A3 problem-solving methodology proved effective in optimizing antibiotic timing and delivery in pediatric surgery.
- Systems-based interventions successfully improved adherence to prophylactic antibiotic protocols.
- This initiative demonstrates a successful approach to enhancing perioperative care in pediatric surgical settings.
Objectives:
To optimize prophylactic antibiotic timing and delivery across all surgeries performed at a single large pediatric tertiary care center.
Methods:
A multidisciplinary surgical quality team conducted a quality improvement initiative from July 2015 to December 2019 by using the A3 problem-solving method to identify and evaluate interventions for appropriate antibiotic administration. The primary outcome measure was the percentage of surgical encounters for pediatric patients with appropriate timing of antibiotic administration before surgical incision. Surgical site infection rates was the secondary outcome. Intervention effectiveness was assessed by using statistical process control.
Results:
A total of 32 192 eligible surgical cases for pediatric patients were completed during the study period. Identified barriers to timely perioperative antibiotic administration included failure to order antibiotics before the surgical date and lack of antibiotic availability in the operating room at the time of administration. Resulting sequential interventions included updating institutional guidelines to reflect procedure-specific antibiotic choices and clarifying timing of administration to optimize pharmacokinetics, creating a hard-stop antibiotic order within electronic health record case requests, optimizing pharmacy and nursing workflow, and implementing an automatic antibiotic prophylaxis timer in the operating room. Administration of prophylactic antibiotics during the recommended preincision time window significantly improved; the correct timing was recorded in 38.6% of preintervention cases versus 94.0% at the conclusion of rollout of the sequential interventions (P < .001). Surgical site infection rates remained stable.
Conclusions:
Here we demonstrate utility of the A3 problem-solving schematic to successfully optimize prophylactic antibiotic timing and delivery in the surgical setting for pediatric patients by implementing systems-based interventions.
