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.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

backgroundAccountable care organizations (ACOs) were established to improve care and outcomes for beneficiaries requiring highly coordinated, complex care. The objective of this study was to evaluate the association between hospital ACO participation and the outcomes of major surgical oncology procedures.

methodsThis was a retrospective cohort study of Medicare beneficiaries older than 65 years who were undergoing a major surgical resection for colorectal, bladder, esophageal, kidney, liver, ovarian, pancreatic, lung, or prostate cancer from 2011 through 2013. A difference-in-differences analysis was implemented to compare the postimplementation period (January 2013 through December 2013) with the baseline period (January 2011 through December 2012) to assess the impact of hospital ACO participation on 30-day mortality, complications, readmissions, and length of stay (LOS).

resultsAmong 384,519 patients undergoing major cancer surgery at 106 ACO hospitals and 2561 control hospitals, this study found a 30-day mortality rate of 3.4%, a readmission rate of 12.5%, a complication rate of 43.8%, and a prolonged LOS rate of 10.0% in control hospitals and similar rates in ACO hospitals. Secular trends were noted, with reductions in perioperative adverse events in control hospitals between the baseline and postimplementation periods: mortality (percentage-point reduction, 0.1%; P = .19), readmissions (percentage-point reduction, 0.4%; P = .001), complications (percentage-point reduction, 1.0%; P < .001), and prolonged LOS (percentage-point reduction, 1.1%; P < .001). After accounting for these secular trends, this study identified no significant effect of hospital participation in an ACO on the frequency of perioperative outcomes (difference-in-differences estimator P values, .24-.72).

conclusionsEarly hospital participation in the Medicare Shared Savings Program ACO program was not associated with greater reductions in adverse perioperative outcomes for patients undergoing major cancer surgery in comparison with control hospitals.
