All-cause mortality and suicide within 8 days after emergency department discharge

The Serious Self-Harm Risk of "Mixed Presenters," People Who Presented to New Zealand Emergency Departments for Self-Harm and Other Reasons: A Cohort Study

The objective of this study was to investigate if "Mixed Presenters," people who present to emergency departments at least twice within 28 days, once for self-harm and once for another reason (any order), have an increased risk of subsequent serious self-harm compared to self-harm only repeat presenters. Self-harm coded emergency department data from the Multi-level Intervention for Suicide Prevention (MISP) study was utilized to identify people with at least two presentations to one of eight District Health Boards between 2010 and 2012. First eligible presentation pairs determined their "Mixed Presenter" or "Self-harm Only Presenter" status. The sample was linked to admission and mortality datasets. Survival analysis over the 30-month timeframe was used to determine which presenter group was at higher risk of serious self-harm. Mixed Presenters (n = 1,544), four times more common than Self-harm Only Presenters (n = 377), had an estimated 60% reduced risk of serious self-harm compared to Self-harm Only Presenters. Compared to men, women had a 3.5 times (HR 3.53, 95% CI 2.47-5.06) increased risk. Having an urgent triage code allocated at the index presentation and being admitted at that index presentation were associated with increased serious self-harm risk for Self-harm Only Presenters compared to Mixed Presenters. This study confirms that two presentations for self-harm within a short timeframe indicate high risk of serious self-harm in the future. As men often die following single attempts, and Mixed Presenters may transition to being Self-harm Only Presenters, each presentation for self-harm requires serious attention.

Risk Factors and Causes of Short-Term Mortality after Emergency Department Discharge in Older Patients: Using Nationwide Health Insurance Claims Data

Background

The purpose of this study was to identify the risk factors and causes of short-term mortality after emergency department (ED) discharge in older patients.

Methods

This population-based cohort study used nationwide health insurance claims data in Korea from 2008 to 2014. The causes of death and diagnoses of patients who died within 1 week after discharge from EDs (1-week ED death) were obtained. The risk factors for 1-week ED death were calculated using Cox proportional hazard regression analyses.

Results

The rate of 1-week ED death was 0.5% among 133,251 individuals aged ≥65 years discharged from EDs. In multivariate analysis, the top five ED discharge diagnoses associated with an increased risk of 1-week ED death were hypotension and vascular disease (adjusted hazard ratio [aHR]=5.11; 95% confidence interval [CI], 3.03–8.63), neoplasm (aHR=4.89; 95% CI, 3.77–6.35), coronary artery disease (aHR=3.83; 95% CI, 2.73–5.39), dyspnea (aHR=3.41; 95% CI, 2.48–4.68), and respiratory disease (aHR=2.25; 95% CI, 1.73–2.92). The most common causes of 1-week ED death were neoplasm (14.8%), senility (13.8%), and cerebrovascular disease (11.7%).

Conclusion

Neoplasm, coronary artery disease, and respiratory disease were the discharge diagnoses associated with an increased risk of short-term mortality after ED discharge. Neoplasm was the leading cause of short-term mortality after ED discharge in older patients.

Risk of death within 7 days of discharge from emergency departments with different organizational models

OBJECTIVE

The aim of this study is to investigate the association between emergency department (ED) organizational models and the risk of death within 7 days of ED discharge.

PATIENTS AND METHODS

We included Danish ED discharges between 1 January 2011 and 24 December 2014 that led to death within 7 days of discharge. The inclusion criterion was age older than 18 years. The exclusion criterion was further in-hospital admission. First model (Virtual): other departments employ interns who perform ED tasks. They are responsible for ED patient care and prioritize their task order between their own department and the ED. Second model (Hybrid): the ED/other departments perform tasks; interns/consultants are employed by the ED/other departments. The ED/other departments have patient care responsibility. Third model (Independent): the ED performs all tasks; employs interns/consultants; and have patient care responsibility. Sex, age, Charlson Comorbidity Index score, and primary diagnosis were used to describe patient characteristics. We calculated the risk of death within 7 days of discharge using multiple logistic regression analysis.

RESULTS

In 805 out of 201 299 discharges included in the study, the patient died within 7 days. Compared with the Virtual model, the odds ratio for death within 7 days of discharge was 0.72 (95% confidence interval: 0.59-0.92) for the Independent model and 0.75 (95% confidence interval: 0.61-0.92) for the Hybrid+Virtual model. Increased risk was associated with male sex, older age, and a medium or a high Charlson Comorbidity Index score.

CONCLUSION

Compared with discharges from a Virtual model, the risk of death within 7 days of discharge was lower if the ED had an Independent or a Hybrid+Virtual model.

Suicide Attempts After Emergency Room Visits: The Effect of Patient Safety Goals

In 2007 the Joint Commission National Patient Safety Goals included a requirement addressing risks associated with patient suicidality. The rational for this requirement was that suicide has been the most frequently reported sentinel event since the inception of the Sentinel Event Policy in 1996. The Patient Safety Goals on suicide required hospitals implement actions to assess suicide risk, meet client's immediate safety needs and provide information such as a crisis hotline to individuals and family members for crisis situations. This study performed a secondary data analysis to assess the effect of the 2007 Joint Commission Patient Safety Goals on suicide attempts among patients following treatment at hospital emergency rooms among individuals enrolled in the Florida Medicaid program. A difference-in-difference approach compared changes in rates of suicide attempts for individuals with a primary mental health diagnosis and individuals with a physical health diagnosis after emergency room treatment. In the 6 months following treatment, suicide rates declined after implementation of the goals among patients treated for a primary mental health diagnosis, and increased among patients with a poisoning diagnosis, compared to individuals with a physical health diagnosis. The goals were associated with a reduction in suicide attempts after emergency room treatment.

Early postoperative emergency department presentation predicts poor long-term outcomes in patients surgically treated for meningioma

Previous authors have identified a number of factors that predict morbidity, mortality, and recurrence in patients undergoing resection of a meningioma. We sought to study a novel potential prognostic indicator: early postoperative visit to the emergency department (ED). We conducted a retrospective cohort study on 239 patients who underwent a meningioma resection at our institution between 2001 and 2013 with over 3 months of follow-up postoperatively. All postoperative entries in the medical record were reviewed to identify any ED visit with a neurologic or wound-related complaint within a 90 day postoperative period. The relationships between ED presentation, tumor grade, and extent of surgical resection with future risk of operative recurrence and mortality were analyzed using Fisher's exact test. Variables associated with increased risks of mortality or operative recurrence in a univariate analysis were then included in the multivariate logistic regression model. Patients with a postoperative ED visit were found to be significantly more likely to die during the follow-up period (23.0% versus 4.85%, p<0.0001) or develop an eventual operative recurrence (12.2% versus 3.0%, p=0.0131). Postoperative ED presentation was found to be associated with a higher risk of mortality and operative recurrence independent of pathological tumor grade (p<0.0001 and p=0.0102, respectively). Presentation to the ED is associated with significantly higher rates of future operative recurrence and mortality in patients with recent meningioma resections. This poor prognostic relationship is independent of tumor pathological grade. Increased vigilance and follow-up may be warranted in such patients.

Survival of patients with alcohol use disorders discharged from an emergency department: a population-based cohort study

OBJECTIVES

The aim was to study the cause-specific mortality of users of the emergency department (ED) who received a diagnosis of alcohol use disorder (AUD) in comparison with mortality of other users of the department.

DESIGN

A population-based prospective cohort study.

PARTICIPANTS

All patients aged 18 years and above who were subsequently discharged home from the ED during the years 2002-2008. A total of 107,237 patients were followed by record linkage to a nationwide cause-of-death registry: 1210 patients with AUD as the main discharge diagnosis and 106,027 patients in the comparison group. HR and 95% CIs were calculated.

SETTING

ED at Landspitali-the National University Hospital of Iceland, Reykjavik, Iceland. The hospital offers tertiary care and is the number one trauma centre and community hospital for the greater Reykjavik area. According to the population registry, 78% of the inhabitants of the area attended the ED during the study period.

RESULTS

72 patients died in the AUD group and 4807 in the comparison group. The adjusted HR for all causes of death was 1.91 (95% CI 1.51 to 2.42). The HR for AUDs was 47.68 (95% CI 11.56 to 196.59) while for alcohol liver disease the HR was 19.06 (95% CI 6.07 to 59.87). The HR was also elevated for diseases of the circulatory system: HR 2.52 (95% CI 1.73 to 3.68); accidental poisoning: HR=13.64, (95% CI 3.98 to 46.73); suicide: HR=2.72 (95% CI 1.08 to 6.83); and event of undetermined intent: HR=10.89 (95% CI 4.53 to 26.16).

CONCLUSIONS

AUD as the discharge diagnosis at the ED, among patients who were not admitted to a hospital ward but discharged home, predicts increased mortality. As the results conclusively show the vulnerability of these patients, one can question whether their needs are adequately met at the ED.
