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

backgroundAlthough patients with lower socioeconomic status are at higher risk of obesity, bariatric surgery utilization among patients with Medicaid is low and may be due to program-specific variation in access. Our goal was to compare bariatric surgery programs by percentage of Medicaid cases and to determine if variation in distribution of patients with Medicaid could be linked to adverse outcomes.

methodsUsing a state-wide bariatric-specific data registry that included 43 programs performing 97,207 cases between 2006 and 2020, we identified all patients with Medicaid insurance (n = 4780, 4.9%). Bariatric surgery programs were stratified into quartiles according to the percentage of Medicaid cases performed and we compared program-specific characteristics as well as baseline patient characteristics, risk-adjusted complication rates and wait times between top and bottom quartiles.

resultsProgram-specific distribution of Medicaid cases varied between 0.69 and 22.4%. Programs in the top quartile (n = 11) performed 18,885 cases in total, with a mean of 13% for Medicaid patients, while programs in the bottom quartile (n = 11) performed 32,447 cases in total, with a mean of 1%. Patients undergoing surgery at programs in the top quartile were more likely to be Black (20.2% vs 13.5%, p < 0.0001), have diabetes (35.1% vs 29.5%, p < 0.0001), hypertension (55.1% vs 49.6%, p < 0.0001) and hyperlipidemia (47.6% vs 45.2%, p < 0.0001). Top quartile programs also had higher complication rates (8.4% vs 6.6%, p < 0.0001), extended length of stay (5.6% vs 4.0%, p < 0.0001), Emergency Department visits (8.1% vs 6.5%, p < 0.0001) and readmissions (4.7% vs 3.9%, p < 0.0001). Median time from initial evaluation to surgery date was also significantly longer among top quartile programs (200 vs 122 days, p < 0.0001).

conclusionsBariatric surgery programs that perform a higher proportion of Medicaid cases tend to care for patients with greater disease severity who experience delays in care and also require more resource utilization. Improving bariatric surgery utilization among patients with lower socioeconomic status may benefit from insurance standardization and program-centered incentives to improve access and equitable distribution of care.
