Primary triage nurses do not divert patients away from the emergency department at times of high in-hospital bed occupancy - a retrospective cohort study

Background: Emergency department (ED) overcrowding is frequently described in terms of input- throughput and output. In order to reduce ED input, a concept called primary triage has been introduced in several Swedish EDs. In short, primary triage means that a nurse separately evaluates patients who present in the Emergency Department (ED) and either refers them to primary care or discharges them home, if their complaints are perceived as being of low acuity. The aim of the present study is to elucidate whether high levels of in-hospital bed occupancy are associated with decreased permeability in primary triage. The appropriateness of discharges from primary triage is assessed by 72-h revisits to the ED. Methods: The study is a retrospective cohort study on administrative data from the ED at a 420-bed hospital in southern Sweden from 2011-2012. In addition to crude comparisons of proportions experiencing each outcome across strata of in-hospital bed occupancy, multivariate models are constructed in order to adjust for age, sex and other factors. Results: A total of 37,129 visits to primary triage were included in the study. 53.4 % of these were admitted to the ED. Among the cases referred to another level of care, 8.8 % made an unplanned revisit to the ED within 72 h. The permeability of primary triage was not decreased at higher levels of in-hospital bed occupancy. Rather, the permeability was slightly higher at occupancy of 100-105 % compared to <95 % (OR 1.09 95 % CI 1.02-1.16). No significant association between in-hospital bed occupancy and the probability of 72-h revisits was observed. Conclusions: The absence of a decreased permeability of primary triage at times of high in-hospital bed occupancy is reassuring, as the opposite would have implied that patients might be denied entry not only to the hospital, but also to the ED, when in-hospital beds are scarce

Pre-hospital conditions affecting the hospitalization risk in older adults at the Emergency Department

BACKGROUND: The Emergency Department (ED) is a common route to hospitalization for critically ill and older adults. Older patients are admitted to hospital at a higher rate and have longer length of stay (LOS) when hospitalized. To be able to confront an increasing aging population, meet their medical needs and influence rising costs of health care, there is a need to focus on the older population. In Scandinavia, few studies are made that focus on the geriatric population at the ED. It is essential to early identify risk factors for hospitalization at the ED to improve the medical care for older adults and the influence of prehospital comorbidities. METHOD: This is a retrospective observational study of older adults visiting the ED in southwest Sweden. The aim of this study was to examine if routinely collected patient demographics and prehospital comorbidities were associated with ED disposition and in-patient process outcomes. The data collection was generated from the Regional Healthcare Information Platform. The variables extracted were age, gender, ED-visits, LOS at ED, admission rate, in-hospital LOS and comorbidities before visiting the ED. RESULTS: A total of 15528 patients aged \u3e 65 years visited the ED during 2016, 8098 (52%) were female and 7 430 (48%) were male, 6631 (41%) were 65-74 years of age, 5585 (36%) were 75-84 years of age and 3612 (23%) were 85 years or older. LOS at the ED were over 4 hours for 45% of the population. Patients aged 85 or older had a Hazard ratio of 2.56 (CI 2.33-2.82) for admission and patients with HF had a Hazard ratio of 1.75 (CI 1.46-2.09). CONCLUSION: Patients with old age, HF and comorbidities as prehospital conditions have a significant higher risk for admission to the hospital and a longer in-hospital stay regardless reason for the ED visit. The awareness of this could help physicians identify older patients with high risk for admission and to early initiate an admission plan to be able to reduce LOS at the ED

The probability of readmission within 30 days of hospital discharge is positively associated with inpatient bed occupancy at discharge - a retrospective cohort study.

Previous work has suggested that given a hospital's need to admit more patients from the emergency department (ED), high inpatient bed occupancy may encourage premature hospital discharges that favor the hospital's need for beds over patients' medical interests. We argue that the effects of such action would be measurable as a greater proportion of unplanned hospital readmissions among patients discharged when the hospital was full than when not. In response, the present study tested this hypothesis by investigating the association between inpatient bed occupancy at the time of hospital discharge and the 30-day readmission rate
