It is unclear however, what specific factors account for this increased LOS. This study attempts to define which diagnoses most impact LOS for IEH and if there are differences based on their demographics.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A retrospective cohort study was conducted looking at ICD\u201010 diagnosis codes and LOS for patients identified as IEH seen in Emergency Departments (ED) and also for those admitted to hospital. Data were stratified based on diagnosis, gender, and age. Statistical analysis was conducted to determine which ICD\u201010 diagnoses were significantly associated with increased ED and inpatient LOS for IEH compared to housed individuals.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Homelessness was associated with increased LOS regardless of gender or age group. The absolute mean difference of LOS between IEH and housed individuals was 1.62\u2009h [95% CI 1.49\u20131.75] in the ED and 3.02 days [95% CI 2.42\u20133.62] for inpatients. Males age 18\u201324 years spent on average 7.12 more days in hospital, and females aged 25\u201334 spent 7.32 more days in hospital compared to their housed counterparts. Thirty\u2010one diagnoses were associated with increased LOS in EDs for IEH compared to their housed counterparts; maternity concerns and coronary artery disease were associated with significantly increased inpatient LOS.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Homelessness significantly increases the LOS of individuals within both ED and inpatient settings. We have identified several diagnoses that are associated with increased LOS in IE; these should inform the prioritisation and development of targeted interventions to improve the health of IEH.<\/jats:p><\/jats:sec>","DOI":"10.1111\/jep.14236","type":"journal-article","created":{"date-parts":[[2024,12,29]],"date-time":"2024-12-29T05:55:08Z","timestamp":1735451708000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Illnesses Associated With Increased Length of Stay for Individuals Experiencing Homelessness: A Retrospective Cohort Study of Emergency Department Visits and Hospitalisations"],"prefix":"10.1111","volume":"31","author":[{"given":"S.","family":"Monty Ghosh","sequence":"first","affiliation":[{"name":"Department of Medicine, Faculty of Medicine &amp;
