Clinical Momentum: An Observational Study Identifying Latent Forces Driving Surgical Interventions for Older Adults Near the End of Life.
Article in Annals of surgery, 2025. 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
objectiveWe evaluated the empirical fit of our model of clinical momentum for older adults with life-limiting illness undergoing unplanned surgery.
backgroundOlder adults often undergo surgery near the end of life, in contrast to generally stated preferences. Systems forces promoting intervention may produce nonbeneficial treatment despite advances in communication. We conducted an observational study to understand how a conceptual model of clinical momentum might apply to patients with life-limiting illnesses having surgery.
methodsWe interviewed 29 interdisciplinary clinicians caring for 8 patients age 65+ with life-limiting illness who underwent unplanned surgical intervention. We evaluated physical, cognitive, and social behavioral processes related to the course of care. We used content analysis to code interview transcripts and higher-level analysis to understand the empirical fit of the conceptual model.
resultsWe found evidence of model components, including "fix it" and "recognition-primed decision-making" that related to actual clinical events and processes that occurred for patients, promoting a default of surgical intervention followed by an accumulating "cascade" of interventions that generated a perception of "sunk costs." We identified novel momentum accelerators including binary options and care fragmentation. Clinicians expressed concerns that surgery was nonbeneficial but were unable to disrupt this momentum in the moment of decision-making around surgery. We identified momentum disruption when the patient's abnormality could not be fixed and additional surgery was not considered or offered.
conclusionsClinical momentum characterizes systems forces leading to acute surgical intervention for patients with life-limiting illnesses despite surgeon concerns that the treatment does more harm than good. These forces are difficult to disrupt and may require interventions beyond improved communication to reduce nonbeneficial therapy.
