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

introductionPrevious reports indicate urological surgeries are associated with high rates of hospital re-admission. This study aims to identify factors associated with emergency room (ER) encounters following urological outpatient surgery.

methodsAll outpatient surgeries performed at The Ottawa Hospital between April 1, 2008, and March 31, 2018 by urology, general surgery, gynecology, and thoracic surgery were identified. All ER encounters within 90 days of surgery were captured. Rates of ER encounters by surgical service and procedure type were determined. Patient and surgical factors associated with ER encounters were identified. Factors included age, sex, marital status, presence of primary care provider, procedure, and American Society of Anesthesiologists (ASA) score.

resultsA total of 38 377 outpatient surgeries by the included surgical services were performed during the study period, of which urology performed 16 552 (43.1%). Overall, 5641 (14.7%) ER encounters were identified within 90 days of surgery, including 2681 (47.5%) after urological surgery. On multivariable analysis, higher ASA score IV vs. I was associated with higher risk of ER encounter (relative risk [RR] 1.95, 95% confidence interval (CI) 1.46-2.5) and being married was associated with a lower risk of ER encounter (RR 0.85, 95% CI 0.77-0.93). Urological surgeries with the highest risk of ER encounters, compared to the lowest risk procedure (circumcision), were greenlight laser photo vaporization of the prostate (PVP) (RR 3.2, 95% CI 1.8-5.61), ureteroscopy (RR 3.2, 95% CI 1.9-5.4), and ureteric stent insertion (RR 3.1, 95% CI 1.8-5.5).

conclusionsER encounters following outpatient surgery are common. This study identifies risk factors to recognize patients that may benefit from additional support to reduce ER care needs.
