Objective: To determine which factors predict death occurring in trauma patients who are alive on arrival at hospital Design Prospective cohort study Method Data were collected from 507 trauma patients with multiple injuries, with a Hospital Trauma Index-Injury Severity Score of 16 or more, who were initially delivered by the Emergency Medical Services to the Emergency Department of the University Medical Centre Utrecht (UMCU) during the period 1999-2000. Results: Univariate analysis showed that every year of age increase resulted in a 2% greater risk of death. If the patient had been intubated at the scene of the accident, this risk was increased 4.3-fold. Every point of increase in the Triage Revised Trauma Score (T-RTS) reduced the risk of death by 30%. A similar (but inverse) tendency was found for the HTI-ISS score, with every point of increase resulting in a 5% greater risk of death. There was a clear relationship between the base excess (BE) and hemoglobin (Hb) levels and the risk of death, the latter being increased by 8% for each mmol/l drop in BE, and reduced by 22% for each mmol/l increase in Hb. The risk of death occurring was 2.6 times higher in cases with isolated neurotrauma. These associations hardly changed in the multivariate analysis; only the relation with having been intubated at the scene disappeared. Conclusion: The risk of severely injured accident patients dying after arriving in hospital is mainly determined by the T-RTS, age, presence of isolated neurological damage, BE and Hb level. Skull/brain damage and hemorrhage appear to be the most important causes of death in the first 24 h after the accident. The time interval between the accident and arrival at the hospital does not appear to affect the risk of death.
The earlier observed lower mortality among vulnerably housed and homeless persons with a psychiatric diagnosis compared to vulnerably housed and homeless persons without a psychiatric diagnosis appears to be due to a significantly lower risk of natural causes of death. Compared to controls from the general population, vulnerably housed and homeless persons without registered diagnosis at a local psychiatric service have a significantly increased mortality associated both with natural death causes and with suicide and death due to mental and behavioural disorders. Services for mental health care may deliver an important contribution to the prevention of premature death due to somatic disorders among the socially marginalized.

IntroductionThe mortality among homeless people is linked to the presence of psychiatric disorders.ObjectivesWe compared the risk of specific death causes among clients of the Public Mental Health care (PMHc) in Utrecht with that of the general population, and assessed whether treatment at a local psychiatric service is associated with this risk.AimsTo clarify the association between the presence of a mental disorder and mortality among the socially marginalized.MethodsOut of 8,741 clients in the PMHc register, the records of 6,724 could be linked to the registries of Statistics Netherlands (CBS). Controls (N=66,247) from the population register were personally matched to a PMHc client. A Cox regression analysis was used to estimate hazard ratios (HR) of death.ResultsAn increased all-cause mortality among PMHc clients compared to controls was found (HR=2.99, 95%-CI: 2.63- 3.41), associated with a broad range of death causes.PMHc clients with record linkage to the Psychiatric Case Registry Middle Netherlands (’PMHc+’) had an increased risk of suicide (HR=2.63, 0.99-7.02), but a lower risk of death from natural causes (HR=0.71, 0.54-0.92), compared to PMHc clients without (‘PMHc-’). Compared to controls, however, ‘PMHc-’ clients experienced increased risks of suicide (HR=3.63, 1.42-9.26) and death due to mental & behavioural disorders (HR=7.85, 3.54- 17.43).ConclusionAmong PMHc clients, a registered diagnosis at a local psychiatric service appears to be favourably associated with lower mortality due to natural death causes. The high risk of suicide among ‘PMHc-’ clients probably indicates a high prevalence of undiagnosed mental disorders among PMHc clients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
