1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract

backgroundPrevious analyses evaluating alvimopan included patients at varying risk for ileus after intestinal resection, which may have precluded its widespread adoption. We assess the early and delayed effects of alvimopan in patients stratified by risk for ileus after intestinal and colon resection.

methodsFrom the Premier Perspective database, patients with elective small and large bowel resections from 2012 to 2014 were identified. Multivariable analysis identified 14 perioperative risk factors for postoperative ileus. Within low- (0-4 factors), intermediate- (5 factors), and high-risk (6-12 factors) ileus categories, alvimopan and no-alvimopan patients were propensity-score matched for demographics, morbidities, diagnosis, surgery and approach, postoperative complications, surgeon specialty, and hospital features. In-hospital postoperative ileus, length of stay, discharge destination, and ileus-related readmission were compared.

resultsOf 52,948 patients, 15,719 (29.7%) received alvimopan. Risk for ileus in low- (18,784), intermediate- (14,370), and high-risk (19,794) categories was 8.9, 13, and 22% (p ≤ .0001) respectively. After matching, alvimopan was associated with significantly reduced in-hospital postoperative ileus in all (low, 6%; intermediate, 9.4%; and high risk, 16.2%) categories. Hospital stay and 30-, 60-, and 90-day postdischarge ileus were also significantly lower with alvimopan. For low-risk patients, alvimopan increased discharge to home, while 90-day emergency readmission was reduced.

conclusionsAlvimopan, regardless of ileus risk, improves ileus, hospital stay, and ileus-related readmission after intestinal resection and these effects are sustained over the long term. Since fewer than a third of patients currently receive alvimopan, its routine adoption with small and large intestinal resection will significantly impact patients and health systems.
