摘要

Background

Individuals with diabetes have an increased risk of cardiovascular disease, infection, hospitalization, and premature mortality. However, less is known about how diabetes shapes the broader pattern of emergency department (ED) presentations, acute care use, clinical complexity, and short-term mortality in an unselected ED population. We aimed to describe ED presentation patterns and outcomes among individuals with and without diabetes in a large regional cohort.

Methods

We conducted a population-based cohort study including all adult ED visits to nine hospitals in Region Skåne, Sweden, between 2017 and 2018. ED visits for patients with a registered diabetes diagnosis (n = 60,654) were compared with those without diabetes (n = 502,800). We analysed ED visit frequency, recurrent ED use, arrival by ambulance, triage priority, length of stay, comorbidity burden, presenting complaints, and mortality after ED presentation.

Results

The most common presenting complaints were broadly similar in both groups, with dyspnoea, chest pain, and abdominal pain among the leading causes of ED presentation. However, diabetes visits were characterized by greater acute care complexity. Compared with visits by individuals without diabetes, visits by individuals with diabetes more often involved a previous ED visit within 90 days, higher triage priority, ambulance arrival, longer ED stay, and substantially higher comorbidity burden. Early mortality after ED presentation was also higher among individuals with diabetes and occurred at younger ages, particularly among men. Mortality diagnoses differed between groups, with cardiovascular causes more prominent among individuals with diabetes.

Conclusions

In this large population-based ED cohort, individuals with diabetes presented with broadly similar symptom categories as those without diabetes, but with markedly greater clinical complexity, higher acuity, recurrent acute care use, and earlier mortality. Diabetes in emergency care may therefore identify a patient group with substantial multimorbidity, reduced physiological reserve, and increased vulnerability during acute illness.
