Comprehensive Advances in General Medicine and Trauma Emergency Care: Integrating Surgery, Internal Medicine, and Lifestyle Medicine for Holistic Patient Management

Emergency and trauma care increasingly involves patients with overlapping acute pathology, chronic disease, frailty, infection risk, functional limitation, and modifiable cardiometabolic factors. Although research published between 2020 and 2026 shows important advances in resuscitation, surgery, critical care, rehabilitation, and chronic disease prevention, these domains are often evaluated separately, limiting their translation into coordinated patient-centred care. This narrative review aimed to synthesise recent evidence from 2020 to 2026 on general medicine and trauma emergency care through an integrated framework combining surgery, internal medicine, rehabilitation, and lifestyle medicine. Studies were reviewed across trauma triage, prehospital and emergency resuscitation, operative and non-operative surgical decision-making, perioperative medical optimisation, sepsis management, organ support, analgesia, rehabilitation, lifestyle intervention, and digital follow-up. The evidence suggests that outcomes depend on accurate triage, timely stabilisation, appropriate use of resuscitative adjuncts, individualised surgical decisions, frailty assessment, comorbidity control, antimicrobial stewardship, physiologically guided critical care, multimodal analgesia, graded rehabilitation, and secondary prevention targeting nutrition, physical activity, glycaemic control, and cardiovascular risk. The literature also highlights uncertainties, including variable benefit from prehospital tranexamic acid and blood products, mixed findings on fluid restriction and sedation strategies, implementation barriers, and the need for longer-term functional outcome measures. Integrating emergency medicine, surgery, internal medicine, critical care, geriatrics, rehabilitation, digital health, and lifestyle medicine may improve survival, reduce complications, preserve function, and strengthen continuity of care.
