Incidence and Outcomes of Unplanned Intensive Interventions After Common Inpatient Surgeries: A Population-Based Cohort Study.
Article in Annals of surgery open : perspectives of surgical history, education, and clinical approaches, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
Objective: To determine the incidence, predictors, and outcomes of unplanned intensive interventions after common inpatient surgeries among older adults. Background: Intensive interventions in older adults may profoundly affect prognosis and recovery after surgery, yet their frequency and association with outcomes such as mortality are unknown. Methods: We conducted a retrospective cohort study using Medicare fee-for-service claims (2016-2020), including patients aged ≥66 years who underwent 1 of the 10 most common inpatient surgeries. Unplanned intensive interventions-cardiopulmonary resuscitation, prolonged mechanical ventilation, tracheostomy, new dialysis, extracorporeal membrane oxygenation, or feeding tube placement-were identified during the index hospitalization. Multivariable generalized estimating equation models identified predictors, and propensity score-weighted models assessed 1-year outcomes. Results: Among 1,095,445 surgeries, intensive interventions occurred in 20,669 (1.9%) patients, most commonly cardiopulmonary resuscitation (67.6%) and prolonged ventilation (22.3%). Frailty was the strongest predictor [adjusted odds ratio (aOR) 1.67, 95% confidence interval (CI) 1.60-1.73], followed by urgent/emergent surgery (aOR 1.18, 95% CI 1.13-1.23), older age, male sex, and higher comorbidity burden. Patients experiencing intensive interventions had markedly worse outcomes: inpatient mortality 24.6% versus 0.5% (aOR 51.4, 95% CI 47.1-56.1), 1-year mortality 44.2% versus 5.2% (aOR 11.6, 95% CI 10.8-12.4), and 90-day nursing home admission 8.9% versus 1.8% (aOR 5.0, 95% CI 4.2-5.9). Conclusions: Although uncommon, unplanned intensive interventions after common surgeries are associated with dramatically higher mortality and institutionalization. Frailty, comorbidity, older age, male sex, and urgent/emergent surgery identify patients at greatest risk. These findings support incorporating intensive intervention risk into preoperative discussions and postintervention care planning to promote goal-concordant decisions.
