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

backgroundStructural aspects of health care systems, such as limited access to specialized surgical and perioperative care, can negatively affect the outcomes and resource use of patients undergoing elective and emergency surgical procedures. The aim of this study was to compare postoperative outcomes of Nunavut Inuit and non-Inuit patients at a Canadian quaternary care centre.

methodsWe conducted a retrospective cohort study involving adult (age ≥ 18 yr) patients undergoing inpatient surgery from 2011 to 2018 at The Ottawa Hospital, the quaternary referral hospital for the Qikiqtaaluk Region of Nunavut. The study was designed and conducted in collaboration with Nunavut Tunngavik Incorporated. The primary outcome was a composite of in-hospital death or complications.Secondary outcomes included postoperative length of stay in hospital, adverse discharge disposition, readmissions within 30 days and total hospitalization costs.

resultsA total of 98 701 episodes of inpatient surgical care occurred among patients aged 18 to 104 years; 928 (0.9%) of these involved Nunavut Inuit, and 97 773 involved non-Inuit patients. Death or postoperative complication occurred more often among Nunavut Inuit than non-Inuit patients (159 [17.2%] v. 15 691 [16.1%]), which was significantly different after adjustment for age, sex, surgical specialty, risk and urgency (odds ratio [OR] 1.25, 95% confidence interval [CI] 1.03-1.51). This association was most pronounced in cases of cancer (OR 1.63, 95% CI 1.03-2.58) and elective surgery (OR 1.58, 95% CI 1.20-2.10). Adjusted rates of readmission, adverse discharge disposition, length of stay and total costs were significantly higher for Nunavut Inuit.

interpretationNunavut Inuit had a 25% relative increase in their odds of morbidity and death after surgery at a major quaternary care hospital in Canada compared with non-Inuit patients, while also having higher rates of other adverse outcomes and resource use. An examination of perioperative systems involving patients, Inuit leadership, health care providers and governments is required to address these differences in health outcomes.
