Why older patients of lower clinical urgency choose to attend the emergency department.

BACKGROUND/AIMS: To examine non-clinical factors associated with emergency department (ED) attendance by lower urgency older patients. METHODS: An exploratory descriptive study comprising structured interviews with lower urgency community-dwelling patients aged ≥70 years presenting to a tertiary metropolitan Melbourne public hospital ED. Demographical and clinical characteristics, self-reported feelings of social connectedness, perceived accessibility to primary care, reason for attending ED were measured. RESULTS: One hundred patients were interviewed: mean age 82 years, 56% female, 57% lived alone; 73% presented during business hours, 58% arrived by ambulance, 80% presented for illness, and 65% were discharged home within 48 h. Fifty-six per cent of patients reported feeling socially disconnected, comprising 49% living alone compared with 65% who lived with their spouse/family. All patients attended a regular general practitioner, 31% reporting regular review appointments. Thirty-five per cent reported waiting times >2-3 days for urgent problems; 59% stated accessing care 'after hours' without attending ED as difficult, with 20% having attended ED 3-6 times in the previous 12 months. Reasons for attending ED were referral by a third party, difficulty with accessibility to primary care, patient preferences for timely care and fast-track access to specialist care. CONCLUSIONS: Most older patients of lower clinical urgency presented to ED because of perceived access block to primary or specialist services, alongside an expectation of more timely and specialised care. This suggests that EDs should be redesigned and/or integrated community-based models of care developed to meet the specific needs of this age group who have growing demand for acute care.

The association between time to disposition plan in the emergency department and in-hospital mortality of general medical patients.

BACKGROUND: A perceived risk of time-limited emergency department (ED) assessment of patients is inadequate workup leading to inappropriate disposition. The aim of this study was to examine the association of time to disposition plan (TDP) on ED length of stay (LOS) and correlate this to mortality. METHODS: A retrospective review of data collected from ED information systems at three hospitals was conducted between June 2008 and October 2009. Included patients were admitted to a general medical unit. Patients were excluded if admitted to intensive care, coronary care, a cardiac monitored bed or required surgery in first 24 h or had an expected LOS of <48 h. Multivariate regression analysis was used to identify independent associations with mortality. RESULTS: A total of 10,107 patient episodes was analysed, of which 6768 patients (67.0%) had an ED LOS of ≥8 h. There was significant effect modification by ED LOS in the association of TDP and mortality. In the setting of longer ED LOS, a TDP of <4 h was associated with significantly higher mortality (OR 1.57, 95% CI: 1.28-1.92, P < 0.001), corrected for age, gender and triage category. This association was not significant when ED LOS was <8 h (OR 0.88, 95% CI: 0.60-1.27, P = 0.49). CONCLUSIONS: In the setting of prolonged ED LOS, completing ED assessment and management within 4 h of presentation was associated with significantly higher mortality. Further prospective studies are required to understand the relationship between rapid decision making in the ED and patient safety.
