The Impact of Homelessness, Substance Use, and Mental Illness on Surgical Inpatient Outcomes in Australia.

This study investigated inpatient surgical outcomes for people experiencing homelessness (PEH) in Australia. Retrospective administrative health data of emergency surgical admissions from a single center over five years, 2015 to 2020, was included. Independent associations between factors and outcomes were analyzed with binary logistic and log-linear regression. Of 11 229 admissions, 2% were experiencing homelessness. People experiencing homelessness were on average younger (49 vs 56 years), more likely to be males than females (77% vs 61%), suffer mental illness (10% vs 2%), and substance use disorders (54% vs 10%). People experiencing homelessness were not more likely to suffer surgical complications. However, male sex, older age, mental illness, and substance use were risk factors for poor surgical outcomes. Homelessness predicted greater odds of discharge against medical advice (4.3 times) and longer length of stay (1.25 times). These results highlighted the need for health interventions simultaneously addressing physical, mental health, and substance use issues in the care of PEH.

Demystifying α-gal syndrome: identification and risk management in the perioperative setting.

PURPOSE OF REVIEW: α-Gal syndrome is among a vexing perioperative consideration for anesthesiologists. Commonly referred to as 'red meat allergy', α-Gal syndrome is precipitated by a lone star tick bite resulting in the formation of immunoglobulin E (IgE) antibodies against the tick salivary glycoproteins and noncatarrhine mammalian tissue. RECENT FINDINGS: Up to 20% of the population in the southeastern United States may test positive for IgE antibodies to α-Gal. Increasingly, recognition of α-Gal syndrome as an immune response to red meat consumption and certain drugs, many of which may be administered within the perioperative period, has led to greater awareness of the insidious nature of its presentation - from mild urticaria and gastrointestinal symptoms to severe anaphylaxis. SUMMARY: With the increasing prevalence and identification of α-Gal syndrome, a safe and tailored perioperative process is needed to integrate a pathway that involves multidisciplinary communication, robust information sharing platform, and a structured peri-procedure management.
