Implementing PDSA Methodology for Pediatric Appendicitis Increases Care Value for a Tertiary Children's Hospital

We used the plan-do-study-act (PDSA) framework to develop and implement an evidence-based clinical practice guideline (CPG) within an urban, tertiary children's referral center.

We developed an evidence-based CPG for appendicitis using iterative PDSA cycles. Similar CPGs from other centers were reviewed and modified for local implementation. Adjuncts included guideline-specific order sets and operative notes in the electronic medical record system. Outcomes included length of stay (LOS), 30-day readmissions, hospital costs, and patient and family experience (PFE) scores. Our team tracked outcome, process, and balancing measures using Statistical Process Charts. Outcome measures were compared over 2 fiscal quarters preimplementation and 3 fiscal quarters postimplementation, using interrupted time series, student t test, and chi-square tests when appropriate.

LOS for simple (uncomplicated) appendicitis decreased to 0.87 days (interquartile range [IQR] 0.87-0.94 days) from 1.1 days (IQR 0.97-1.42 days). LOS for complicated appendicitis decreased to 4.96 days (IQR 4.95-6.15) from 5.58 days (IQR 5.16-6.09). This reduction equated to an average cost-savings of $1,122/patient. Thirty-day readmission rates have remained unchanged. PFE scores increased across all categories and have remained higher than national benchmarks.

Development and Implementation of a CPG for pediatric appendicitis using the PDSA framework adds value to care provided within a large tertiary center.
