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

In an effort to reduce episode payment variation for joint replacement at US hospitals, the Centers for Medicare and Medicaid Services (CMS) recently implemented the Comprehensive Care for Joint Replacement bundled payment program. Some stakeholders are concerned that the program may unintentionally penalize hospitals because it lacks a mechanism (such as risk adjustment) to sufficiently account for patients' medical complexity. Using Medicare claims for patients in Michigan who underwent lower extremity joint replacement in the period 2011-13, we applied payment methods analogous to those CMS intends to use in determining annual bonuses or penalties (reconciliation payments) to hospitals. We calculated the net difference in reconciliation payments with and without risk adjustment. We found that reconciliation payments were reduced by $827 per episode for each standard-deviation increase in a hospital's patient complexity. Moreover, we found that risk adjustment could increase reconciliation payments to some hospitals by as much as $114,184 annually. Our findings suggest that CMS should include risk adjustment in the Comprehensive Care for Joint Replacement program and in future bundled payment programs.
