Evaluation of Textbook Outcome as a Composite Quality Measure of Elective Laparoscopic Cholecystectomy

Key Points

Question

Can the concept of textbook outcome (TO) be applied to elective laparoscopic cholecystectomy (LC), and if so, what are the TO criteria and the characteristics associated with TO failure?

Findings

In this cohort study of 2166 participants undergoing elective LC, 1851 (85.5%) achieved a TO with an unremarkable perioperative course. Predisposing factors and those contributing to TO failure were identified.

Meaning

These findings suggest that applying the concept of TO to elective LC provides a benchmark to enable institutions to identify strategies for quality improvement.

Abstract

This cohort study proposes the textbook outcome criteria after elective cholecystectomy and identifies reasons for failure and individual patient factors predisposing to failure.

Abstract

Importance

A textbook outcome (TO) is a composite quality measure that incorporates multiple perioperative events to reflect the most desirable outcome. The use of TO increases the event rate, captures more outcomes to reflect patient experience, and can be used as a benchmark for quality improvement.

Objectives

To introduce the concept of TO to elective laparoscopic cholecystectomy (LC), propose the TO criteria, and identify characteristics associated with TO failure.

Design, Setting, and Participants

This retrospective cohort study was performed at 3 surgical units in a single health board in the United Kingdom. Participants included all patients undergoing elective LC between January 1, 2015, and January 1, 2020. Data were analyzed from January 1, 2015, to January 1, 2020.

Main Outcomes and Measures

The TO criteria were defined based on review of existing TO metrics in the literature for other surgical procedures. A TO was defined as an unremarkable elective LC without conversion to open cholecystectomy, subtotal cholecystectomy, intraoperative complication, postoperative complications (Clavien-Dindo classification ≥2), postoperative imaging, postoperative intervention, prolonged length of stay (>2 days), readmission within 100 days, or mortality. The rate of TOs was reported. Reasons for TO failure were reported, and preoperative characteristics were compared between TO and TO failure groups using both univariate analysis and multivariable logistic regressions.

Results

A total of 2166 patients underwent elective LC (median age, 54 [range, 13-92] years; 1579 [72.9%] female). One thousand eight hundred fifty-one patients (85.5%) achieved a TO with an unremarkable perioperative course. Reasons for TO failure (315 patients [14.5%]) included conversion to open procedure (25 [7.9%]), subtotal cholecystectomy (59 [18.7%]), intraoperative complications (40 [12.7%]), postoperative complications (Clavien-Dindo classification ≥2; 92 [29.2%]), postoperative imaging (182 [57.8%]), postoperative intervention (57 [18.1%]), prolonged length of stay (>2 days; 142 [45.1%]), readmission (130 [41.3%]), and mortality (1 [0.3%]). Variables associated with TO failure included increasing American Society of Anesthesiologists score (odds ratio [OR], 2.55 [95 CI, 1.69-3.85]; P < .001), increasing number of prior biliary-related admissions (OR, 2.68 [95% CI, 1.36-5.27]; P = .004), acute cholecystitis (OR, 1.42 [95% CI, 1.08-1.85]; P = .01), preoperative endoscopic retrograde cholangiopancreatography (OR, 2.07 [95% CI, 1.46-2.92]; P < .001), and preoperative cholecystostomy (OR, 3.22 [95% CI, 1.54-6.76]; P = .002).

Conclusions and Relevance

These findings suggest that applying the concept of TO to elective LC provides a benchmark to identify suboptimal patterns of care and enables institutions to identify strategies for quality improvement.
