Impact of Early Postoperative Oral Nutritional Supplement Utilization on Clinical Outcomes in Colorectal Surgery
Bibliographic record
Abstract
Abstract Background: Small randomized trials of early postoperative oral nutritional supplementation (ONS) suggest various health benefits following colorectal surgery (CRS). However, real-world evidence of the impact of early ONS on clinical outcomes in CRS is lacking. Methods: Using a nationwide administrative-financial database (Premier Healthcare Database), we examined the association between early ONS use and postoperative clinical outcomes in patients undergoing elective open or laparoscopic CRS between 2008–2014. Early ONS was defined as the presence of charges for ONS before postoperative day (POD) 3. The primary outcome was composite infectious complications. Key secondary efficacy (intensive care unit (ICU) admission and gastrointestinal complications) and falsification (blood transfusion and myocardial infarction) outcomes were also examined. Propensity score matching was used to assemble patient groups that were comparable at baseline and differences in outcomes were examined. Results: Overall, patients receiving early ONS were older with greater comorbidities, and more likely to be Medicare beneficiaries with malnutrition. In a well-matched sample of early-ONS recipients (n=267) versus non-recipients (n= 534), infectious complications were significantly lower in early-ONS recipients (6.7% vs. 11.8%, P <0.03). Early-ONS use was also associated with significantly reduced rates of pneumonia ( P <0.04), ICU admissions ( P <0.04), and gastrointestinal complications ( P <0.05). There were no significant differences in falsification outcomes. Conclusions: Although early postoperative ONS after CRS was more likely to be utilized in elderly patients with greater comorbidities, use of early ONS was associated with reduced infectious complications, pneumonia, ICU admission, and gastrointestinal complications. This propensity-score matched study using real-world data suggests that clinical outcomes are improved with early ONS use, a simple and inexpensive intervention in CRS patients.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
