Outpatient psychiatric service use is associated with a reduced risk of 1‐year readmission and mortality following alcohol‐related hospitalizations: A historical cohort study
Bibliographic record
Abstract
INTRODUCTION: Alcohol-related hospitalizations are common and associated with high rates of short-term readmission and mortality. Providing rapid access to physician-based mental health and addiction (MHA) services post-discharge may help to reduce the risk of adverse outcomes in this population. This study used population-based data to evaluate the prevalence of outpatient MHA service use following alcohol-related hospitalizations and its association with downstream harms. METHODS: This was a population-based historical cohort study of individuals who experienced an alcohol-related hospitalization between 2016 and 2018 in Ontario, Canada. The primary exposure was whether an individual received follow-up outpatient MHA services from either a psychiatrist or primary care physician within 30 days of discharge from the index hospitalization. The outcomes of interest were alcohol-related hospital readmission and all-cause mortality in the year following discharge from the index alcohol-related hospitalization. Information on health service use and mortality was captured using comprehensive health administrative databases. The associations between receiving outpatient MHA services and the time to each outcome were assessed using multivariable time-to-event regression. RESULTS: A total of 43,343 individuals were included. 19.8% of the cohort received outpatient MHA services within 30 days of discharge. Overall, 19.1% of the cohort was readmitted to hospital and 11.5% of the cohort died in the year following discharge. Receiving outpatient MHA services was associated with a reduced hazard of alcohol-related hospital readmission (adjusted hazard ratio [aHR] 0.94, 95% confidence interval [CI]: 0.88-0.99) and all-cause mortality (aHR: 0.74, 95% CI: 0.66-0.83) after adjusting for demographic and clinical covariates. CONCLUSIONS: Short-term outcomes following alcohol-related hospitalizations are poor. Facilitating rapid access to follow-up MHA services may help to reduce the risk of recurrent harm and death in 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.
