Understanding the surgical care needs and use of outpatient surgical care services among homeless patients at the Ottawa Hospital
Bibliographic record
Abstract
Background: The use of outpatient health care services by homeless people is low compared to their high level of need; however, it is unclear whether this applies to surgical care. We sought to describe surgical care access among homeless patients in a Canadian tertiary care setting. Methods: We reviewed the medical records of adult (age > 18 yr) patients with no fixed address or a shelter address who presented to The Ottawa Hospital Emergency Department from Jan. 1, 2013, to Dec. 31, 2014, and required surgical referral. We analyzed the data using descriptive statistics. Results: A surgical referral was initiated in 129 emergency department visits for 97 patients (77 men [79%], mean age 46.7 yr). Most patients lived in shelters (77 [79%]) and had provincial health insurance (82 [84%]), but only 35 (36%) had a primary care physician. The mean number visits for any reason was 7.9 (standard deviation 13.7) (range 1–106). The majority of surgical referrals (83 [64.3%]) were for traumatic injuries, and the most frequently consulted service (52 [40.3%]) was orthopedic surgery. Just under half (48 [49%]) of referred patients attended at least 1 outpatient appointment, and only a third (33 [34%]) completed full follow-up. Conclusion: Homeless patients presenting to an emergency department and requiring surgical care were predominantly men living in shelters, most frequently seeking care for traumatic injuries. Current outpatient services may not meet the surgical care needs of these patients, as many do not access them. Alternative approaches to outpatient care must be considered, particularly among high-need services such as orthopedics, to support surgical care access among this population.

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.
