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

backgroundFive million surgical procedures are performed annually in the UK NHS. One in five patients experience postoperative complications, causing longer admissions and additional treatments. However, the economic cost of complications is poorly understood.

methodsThis was a planned analysis of the International Surgical Outcomes Study linked to NHS England Hospital Episode Statistics data, focusing on Payment by Results (PbR), the predominant funding mechanism before COVID-19. The primary outcome was cost of postoperative complications. The secondary outcome was profit-loss, comparing PbR (income) with surgical cost accounting for complications (expenditure). We calculated expenditure of admission by multiplying length of stay by average daily ward or critical care unit costs. We defined income using the tariff linked to PbR.

resultsWe included 5167 patients undergoing surgery in the NHS in England, of whom 848 (16.4%) experienced a complication. Patients were on average 58.9 yr old, with 58.1% female and 41.9% male. Median length of stay was 7 days for patients with complications and 2 days without complications. The average cost of admission for patients with complications was £3100 (95% confidence interval [95% CI]: £2921-3279) compared with £1038 (95% CI: £1006-1070) for patients without complications. Profit-loss analysis, accounting for procedure and length of stay, showed a loss for most surgeries, regardless of complications. Average loss without complications was £930 (95% CI: £866-995) and £850 (95% CI: £629-1071) with complications.

conclusionsPostoperative complications increase expenditure by ∼200%. For most procedures, expenditure exceeds income, independent of complications.
