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

rationaleThe National Quality Forum recently endorsed in-hospital mortality and intensive care unit length of stay (LOS) as quality indicators for patients in the intensive care unit. These measures may be affected by transferring patients to long-term acute care hospitals (LTACs).

objectivesTo quantify the implications of LTAC transfer practices on variation in mortality index and LOS index for patients in academic medical centers.

methodsWe used a cross-sectional study design using data reported to the University HealthSystem Consortium from 2008-2009. Data were from patients who were mechanically ventilated for more than 96 hours. MEASUREMENTS AND MAIN

resultsUsing linear regression, we measured the association between mortality index and LTAC transfer rate, with the hospital as the unit of analysis. Similar analyses were conducted for LOS index and cost index. A total of 137 hospitals were analyzed, averaging 534 transfers to LTAC per hospital during the study period. Mean±SD in-hospital mortality was 24±6.4%, and observed LOS was 30.4±8.2 days. The mean LTAC transfer rate was 15.7±13.7%. Linear regression demonstrated a significant correlation between transfer rate and mortality index (R2=0.14; P<0.0001) and LOS index (R2=0.43; P<0.0001).

conclusionsLTAC hospital transfer rate has a significant impact on reported mortality and LOS indices for patients requiring prolonged acute mechanical ventilation. This is an example of factors unrelated to quality of medical care or illness severity that must be considered when interpreting mortality and LOS as quality indicators.
