Measuring Provider Compliance with an Institution-Based Clinical Pathway for Diverticulitis Using Radiologic Criteria.

BACKGROUND: Diverticulitis remains a common disease encountered in the acute care setting. Management strategies have been developed to guide treatment decisions based on imaging. By using a multi-faceted clinical pathway approach, a standardized method of diagnosing and categorizing disease severity can be performed in order to guide appropriate management. This study evaluated provider compliance with an institutional clinical pathway designed to guide management of diverticulitis.

METHODS: An institutional clinical pathway was developed to manage diverticulitis, including radiologic classification, primary service line assignment, interventional strategies, and antimicrobial treatment. To assess provider compliance with the algorithm, we queried the institutional acute diverticulitis database for patients admitted from May 19, 2016 to February 8, 2017, which identified 83 patients. Provider compliance with the pathway was assessed using subgroup analysis of radiologic documentation (modified Neff [mNeff] classification), primary service assignment, and interventions (i.e., interventional radiology [IR] and antimicrobial agents).

RESULTS: The cohort represented a diverse group of mNeff classifications, predominantly Stage 0. Surgical interventions occurred in 10.8% of the cohort. Antimicrobial agents were administered to 88.0% and 78.3% of the outpatients and inpatients, respectively. Patients received a total duration of antimicrobial therapy (mean ± standard deviation [SD]) of 10.2 ± 5.1 days. Overall compliance occurred in 10% of the patients. Compliance with radiologic documentation, antimicrobial choice, and antimicrobial duration were 90.4%, 20.5%, and 69.9%, respectively.

CONCLUSIONS: Overall compliance with the clinical pathway was poor, except as it related to compliance with radiologic documentation, appropriate assignment to surgical service line, and antimicrobial duration. These results suggest areas for future improvement to augment compliance with the clinical pathway.
