Perioperative Hyperglycemia and Risk of Adverse Events Among Patients With and Without Diabetes
Open accessAbstract
OBJECTIVE: To study the association between diabetes status, perioperative hyperglycemia, and adverse events in a statewide surgical cohort. BACKGROUND: Perioperative hyperglycemia may increase the risk of adverse events more significantly in patients without diabetes (NDM) than in those with diabetes (DM). METHODS: Using data from the Surgical Care and Outcomes Assessment Program, a cohort study (2010-2012) evaluated diabetes status, perioperative hyperglycemia, and composite adverse events in abdominal, vascular, and spine surgery at 53 hospitals in Washington State. RESULTS: Among 40,836 patients (mean age, 54 years; 53.6% women), 19% had diabetes; 47% underwent a perioperative blood glucose (BG) test, and of those, 18% had BG ≥180 mg/dL. DM patients had a higher rate of adverse events (12% vs 9%, P < 0.001) than NDM patients. After adjustment, among NDM patients, those with hyperglycemia had an increased risk of adverse events compared with those with normal BG. Among NDM patients, there was a dose-response relationship between the level of BG and composite adverse events [odds ratio (OR), 1.3 for BG 125-180 (95% confidence interval (CI), 1.1-1.5); OR, 1.6 for BG ≥180 (95% CI, 1.3-2.1)]. Conversely, hyperglycemic DM patients did not have an increased risk of adverse events, including those with a BG 180 or more (OR, 0.8; 95% CI, 0.6-1.0). NDM patients were less likely to receive insulin at each BG level. CONCLUSIONS: For NDM patients, but not DM patients, the risk of adverse events was linked to hyperglycemia. Underlying this paradoxical effect may be the underuse of insulin, but also that hyperglycemia indicates higher levels of stress in NDM patients than in DM patients.

Each is checked against this paper’s own text: does it say what the citing paper says it does?
People who develop stress hyperglycaemia have more adverse peri-operative outcomes than those with diabetes mellitus.
“People who develop stress hyperglycaemia have more adverse peri‐operative outcomes than those with diabetes mellitus [78, 79, 80].”
The Discussion reports higher adverse-event rates in patients without diagnosed diabetes than in patients with diabetes at a given level of perioperative hyperglycemia. The claim omits that matched-glucose comparison: the paper reports higher adverse-event rates in patients with diabetes overall. Its Conclusions also say it remains uncertain whether hyperglycemia in patients without diabetes is a marker of surgical stress. (LLM, conf=0.86)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
