Unscheduled returns to the emergency department: an outcome of medical errors?

National Coroners Information System: a valuable source of lessons for emergency medicine

OBJECTIVE

To interrogate the National Coroners Information System (NCIS) to determine the recurrent themes among coroners' recommendations that aimed to increase the safety of ED care.

METHODS

This was a retrospective analysis of NCIS closed cases, from Queensland, New South Wales, Tasmania, Victoria, Australian Capital Territory, South Australia and North Territory, entered since its inception in 2000. The keyword 'emergency department' returned 1645 cases, of which 180 were found to be relevant. The primary outcomes were the number and nature of cases where recommendations for improvements in ED care had been made and the recurrent themes of these recommendations that could inform education initiatives.

RESULTS

Of the 180 cases, 108 (60.0%) were of deceased men and subject age ranged from 2 days to 91 years. The commonest causes of death were trauma (26.7%), infection (24.4%), cardiac events (15.0%) and poisoning (8.9%). No coronial recommendations were required in 19 cases. For the remainder, recommendation themes related to issues of risk management/medico-legal, diagnostic/therapeutic error, education, documentation/communication and re-presentation. The themes associated with the different doctor designations (consultant, registrar, resident/intern) were similar, although registrars and residents/interns tended towards more diagnostic/therapeutic errors. The themes associated with hospital type (referral, urban, regional/rural) were also similar. Although theme analysis is important, some individual cases were particularly instructive.

CONCLUSION

The NCIS data theme analysis identifies important high-risk patients and presenting complaints. These should be incorporated into emergency physician training. EDs should review the coronial recommendations to ensure that, where possible, they have been adopted.

Clinical pathologic conference: A 65-year-old male with left-sided chest pain. A case of an unexpected occupational hazard

The authors present a case of a 65-year-old male who presented four times to the emergency department (ED) with left-sided chest pain. On the first three visits, the patient was admitted with a different diagnosis related to his chest pain. On the final visit, an abnormality on an imaging study performed in the ED led to the ultimate diagnostic test revealing the cause of the patient's symptoms. The patient's clinical presentation and ultimate clinical course are summarized, and a discussion of the differential diagnoses of his condition is presented.

Unplanned return visits to emergency in a regional hospital

Objective. The aim of this study was to determine the patient characteristics associated with unplanned return visits, using routinely collected hospital data, to assist in developing strategies to reduce their occurrence. Methods. Emergency department data from a regional hospital were analysed using univariate and multivariate methods to determine the influence of clinical, service usage and demographic patient characteristics on unplanned return visits. Results. Around 80% of the 16 000 patients attending emergency presented on only one occasion in a year. Five per cent of patients presented with an unplanned return visit. Older patients, those with minor and low urgency conditions and with non-psychotic mental health conditions, those presenting during winter and after hours were significantly more likely to present as unplanned return visits. Conclusion. Although patient characteristics associated with unplanned return visits have been identified, the reasons underpinning the unplanned return visit rate, such as patient service preference and attitudes, need to be more fully investigated. What is known about the topic? Patients who present as unplanned return visits are older and have a range of chronic and acute conditions. Some unplanned return visits occur because of limited access to other non-hospital service. What does this paper add? This paper adds to the field by providing information from a regional hospital in NSW Australia on the patient characteristics associated with unplanned return visits. It provides a basis for differentiating between other groups of frequent emergency department patients. However, the reasons behind the unplanned return visit rate need to be more fully investigated. What are the implications for practitioners? The implications of the findings of this study for policy makers, administrators and clinicians are that access to alternative services for the conditions associated with unplanned return visits need to be further investigated in the context of the role for emergency department services.

Update on the role of palliative oxygen

PURPOSE OF REVIEW

Breathlessness remains a frequent and burdensome symptom for individuals with life-limiting symptoms in both malignant and nonmalignant settings. As oxygen therapy is frequently given as part of the management of breathlessness and is associated with costs, treatment burden and potential dangers, it is timely to review the efficacy and appropriateness of palliative oxygen therapy.

RECENT FINDINGS

Despite the widespread use of oxygen therapy in clinical and community settings, data supporting this approach is sparse. The benefits of long-term oxygen therapy for severely hypoxaemic people with chronic obstructive pulmonary disease are proven; however, mounting evidence suggests that oxygen does not confer additional benefit over medical air for the relief of refractory breathlessness in people with mild or absent hypoxaemia.

SUMMARY

On the basis of the findings of this review, the routine use of palliative oxygen therapy without detailed assessment of pathogenesis and reversibility of symptoms cannot be justified. Promoting self-management strategies, such as cool airflow across the face, exercise and psychological support for patients and carers, should be considered before defaulting to oxygen therapy. If palliative oxygen therapy is considered for individuals with transient or mild hypoxaemia, a therapeutic trial should be conducted with clinical review after 3 days to assess the net clinical benefit and patient preference.

Children admitted to the hospital after returning to the emergency department within 72 hours

OBJECTIVES

Children returning to the emergency department (ED) within 72 hours of their visit may increase overcrowding and health care costs. Identifying the characteristics of returning children who need admission may help distinguish who might need admission on their first visit. The objective of this study was to compare the characteristics of children who returned to the ED and needed admission to the characteristics of those discharged.

METHODS

The study used a retrospective chart review of patients 19 years and younger visiting a tertiary pediatric ED during a 1-year period. We excluded patients who left without being seen and those leaving against medical advice. We determined the rate of return visits and then performed χ² and Student t test analyses. Main outcome measures were return and subsequent hospital admission rate to the ED.

RESULTS

Of 47,655 eligible children, 2115 (4.4%) returned to the ED within 72 hours. The admission rate for the second visit was 353 (16.7%). There was no significant difference in age, sex, language spoken at home, or time elapsing from the first visit to the re-presentation to the ED between children who needed admission on the returned visit and those discharged when returning. The acuity was significantly lower among children discharged after returning (P < 0.001) but not among those admitted (P < 0.22).

CONCLUSIONS

More than 4% of our pediatric ED visits are for children returning within 72 hours. Progression of illness resulting in higher acuity, not age, sex, time from previous visit, or change in chief complaint category, was associated directly with admission on the second visit.

Seventy-two-hour returns may not be a good indicator of safety in the emergency department: a national study

OBJECTIVES

The objective was to measure the association between returns to an emergency department (ED) within 72 hours and resource utilization, severity of illness, mortality, and admission rate.

METHODS

This was a retrospective, cross-sectional analysis of ED visits using data from the National Hospital Ambulatory Medical Care Survey (NHAMCS) from 1998 to 2006. Cohorts were patients who had been seen in the ED within the past 72 hours versus those without the prior visit. A multivariate model was created to predict adjusted-resource utilization and mortality or admission rate.

RESULTS

During the study period, there were 218,179 ED patient visits and a 3.2% 72-hour return rate. Patients with Medicare (3.5%) and without insurance (3.5%) were more likely to return within 72 hours. Visits associated with alcohol (4.1%), low triage acuity (4.0%), or dermatologic conditions (5.9%) were more likely to return. Seventy-two-hour return visits used fewer resources (5.0 [±0.1] vs. 5.5 [±0.1] tests, medications, procedures), were less likely to be Level I triage acuity (17% vs. 20%), and had a similar admission rate (13% vs. 13%) as those not seen within 72 hours. The sample size was too small to evaluate mortality.

CONCLUSIONS

Patients who return to the ED within 72 hours do not use more resources, are not more severely ill, and do not have a higher hospital admission rate than those who had not been previously seen. These findings do not support the use of 72-hour returns as a quality or safety indicator. A more refined variation such as 72-hour returns resulting in admission may have more value.

Staffing of the ED by non-emergency medicine-trained personnel: the VA experience

STUDY OBJECTIVE

VA (Veteran's Affairs) emergency departments (EDs) are generally staffed with physicians trained in internal medicine (IM), although recently, a movement has begun toward hiring emergency medicine (EM)-trained staff. At our institution, the ED is staffed by physicians of both specialties. This study examines the frequency of unscheduled return visits to the ED in an effort to compare the quality of emergency care given by physicians trained in IM and EM.

METHODS

The record of all visits to a VA hospital ED during a 90-day period were examined, and all those visits resulting in a return ED visit within the 30 subsequent days were noted.

RESULTS

The charts of 2891 consecutive ED patients were examined. The rate of revisits was significantly higher for the IM than for the EM-trained physicians (8.9% vs 5.5%, respectively; P < .001). The IM-trained physicians had a significantly higher rate of admissions upon revisit within 30 days than did the EM-trained physicians (3.5% vs 1.9%, respectively; P = .014). The IM-trained staff had lower initial hospitalization rates than the EM physicians (20% vs 43%, respectively; P < .0001).

CONCLUSIONS

The IM-trained physicians were less likely to hospitalize patients, although this can be partially explained by the lower acuity of patients during the hours that they covered. The IM-trained physicians were significantly more likely to have a patient return after discharge and also more likely to have a patient return in need of hospitalization. This may reflect a difference in training for the rapid diagnosis and risk stratification of ED patients.

Unplanned emergency department revisits within 72 hours to a secondary teaching referral hospital in Taiwan

BACKGROUND

When patients return to the emergency department (ED) shortly after being seen, it is generally assumed that their initial evaluation or treatment was inadequate.

OBJECTIVES

The purpose of this study was to determine the rates and causes of revisits to the ED of a 710-bed secondary teaching referral hospital (Kuang Tien General Hospital), to identify areas for improvement, and to define the initial ED presentations that are associated with such revisits.

METHODS

The study period was from January 1, 2006 to December 31, 2006. There were 34,714 patients seen and discharged in the ED; 1899 patients returned within 72 h. Monthly revisit rates were calculated. The patients who revisited the ED within 72 h were retrospectively identified by the authors, and their charts were examined to determine the causes of the revisits.

RESULTS

There were 1899 patients (5.47% of total) found to have revisited the ED within 72 h after their initial visit. The monthly revisit rates ranged from 2.85% to 6.25% (average, 5.47%). The rates of revisits that were related to factors of illness, patients, and doctors were 80.9%, 10.9%, and 8.2%, respectively. Among the factors related to doctors, 3.7% (70 cases) were misdiagnosis, and abdominal pain was the most common presentation (55.7%, 39/70). The most common initial ED presentations were for abdominal pain (12.9%), fever (12.6%), vertigo (4.5%), headache (2.1), and upper respiratory infection (2.1%).

CONCLUSIONS

Unplanned ED revisits are associated with medical errors in prognosis, treatment, follow-up care, and information. Differentiation between the natural course of a disease, suboptimal therapy, over-anxious reaction of the patient, and medical errors is difficult. Although this study indicates that most revisits are illness-related, further prospective studies are needed to evaluate the most common and the most serious causes of revisits to see if improvements can be made.

Socio-demographic and clinical characteristics of re-presentation to an Australian inner-city emergency department: implications for service delivery

Background

People who have complex health care needs frequently access emergency departments for treatment of acute illness and injury. In particular, evidence suggests that those who are homeless, or suffer mental illness, or have a history of substance misuse, are often repeat users of emergency departments. The aim of this study was to describe the socio-demographic and clinical characteristics of emergency department re-presentations. Re-presentation was defined as a return visit to the same emergency department within 28 days of discharge from hospital.

Methods

A retrospective cohort study was conducted of emergency department presentations occurring over a 24-month period to an Australian inner-city hospital. Characteristics were examined for their influence on the binary outcome of re-presentation within 28 days of discharge using logistic regression with the variable patient fitted as a random effect.

Results

From 64,147 presentations to the emergency department the re-presentation rate was 18.0% (n = 11,559) of visits and 14.4% (5,894/40,942) of all patients. Median time to re-presentation was 6 days, with more than half occurring within one week of discharge (60.8%; n = 6,873), and more than three-quarters within two weeks (80.9%; n = 9,151). The odds of re-presentation increased three-fold for people who were homeless compared to those living in stable accommodation (adjusted OR 3.09; 95% CI, 2.83 to 3.36). Similarly, the odds of re-presentation were significantly higher for patients receiving a government pension compared to those who did not (adjusted OR 1.73; 95% CI, 1.63 to 1.84), patients who left part-way through treatment compared to those who completed treatment and were discharged home (adjusted OR 1.64; 95% CI, 1.36 to 1.99), and those discharged to a residential-care facility compared to those who were discharged home (adjusted OR 1.46: 95% CI, 1.03 to 2.06).

Conclusion

Emergency department re-presentation rates cluster around one week after discharge and rapidly decrease thereafter. Housing status and being a recipient of a government pension are the most significant risk factors. Early identification and appropriate referrals for those patients who are at risk of emergency department re-presentation will assist in the development of targeted strategies to improve health service delivery to this vulnerable group.
