The future of emergency medicine

Changes in compensation claim contents following reorganization of emergency hospital care

OBJECTIVES

To study the effects of the reorganization on patient compensation claim contents relating to health care quality and patient safety.

DESIGN AND SETTINGS

Danish emergency care has developed considerably over the past decades, including a major reorganization to improve health care quality and patient safety through ensuring easier access to specialist treatment. Analysis of compensation claim patterns is used to evaluate the effects of such health care system changes.

PARTICIPANTS, INTERVENTIONS AND MAIN OUTCOME MEASURES

A sample of 1613 compensation claims to the Danish Patient Assurance organization was reviewed using a standardized taxonomy (the Healthcare Complaints Analysis Tool [HCAT]). Using trend analysis, we compared the proportions of claims categorized under HCAT domains, problem categories and sub-categories before and after the reorganization, with particular emphasis on the 'Clinical problems' domain covering health care quality and patient safety issues.

RESULTS

We observed a baseline increase in claims relating to clinical problems (P < 0.01), but this increase was less pronounced following the reorganization. This appeared to be driven mainly by a decrease in claims about clinician skills (P = 0.03) and health care neglects (P = 0.01). However, claims about diagnostic errors and patient outcomes showed a tendency (insignificant) to increase.

CONCLUSIONS

Emergency care reorganization apparently has been followed by a shift in claim contents towards fewer claims about health care neglect and staff competencies, although claims about other matters may have become more common. Present analyses of compensation claim trends should be supplemented by effect studies using traditional outcome measures such as mortality and readmission rates.

Closing five Emergency Departments in England between 2009 and 2011: the closED controlled interrupted time-series analysis

Background

In recent years, a number of emergency departments (EDs) have closed or have been replaced by another facility such as an urgent care centre. With further reorganisation of EDs expected, this study aimed to provide research evidence to inform the public, the NHS and policy-makers when considering local closures.

Objective

To understand the impact of ED closures/downgrades on populations and emergency care providers.

Design

A controlled interrupted time series of monthly data to assess changes in the patterns of mortality in local populations and changes in local emergency care service activity and performance, following the closure of type 1 EDs.

Setting

The populations of interest were in the resident catchment areas of five EDs that closed between 2009 and 2011 (in Newark, Hemel Hempstead, Bishop Auckland, Hartlepool and Rochdale) and of five control areas.

Main outcome measures

The primary outcome measures were ambulance service incident volumes and times, the number of emergency and urgent care attendances at EDs, the number of emergency hospital admissions, mortality, and case fatality ratios.

Data sources

Data were sourced from the Office for National Statistics, Hospital Episode Statistics (HES) accident and emergency, HES admitted patient care and ambulance service computer-aided dispatch records.

Results

There was significant heterogeneity among sites in the results for most of the outcome measures, but the overall findings were as follows: there is evidence of an increase, on average, in the total number of incidents attended by an ambulance following 999 calls, and those categorised as potentially serious emergency incidents; there is no statistically reliable evidence of changes in the number of attendances at emergency or urgent care services or emergency hospital admissions; there is no statistically reliable evidence of any change in the number of deaths from a set of emergency conditions following the ED closure in any site, although, on average, there was a small increase in an indicator of the ‘risk of death’ in the closure areas compared with the control areas.

Limitations

Unavailable or unreliable data hindered some of the analysis regarding ED and ambulance service performance.

Conclusions

Overall, across the five areas studied, there was no statistically reliable evidence that the reorganisation of emergency care was associated with an increase in population mortality. This suggests that any negative effects caused by increased journey time to the ED can be offset by other factors; for example, if other new services are introduced and care becomes more effective than it used to be, or if the care received at the now-nearest hospital is more effective than that provided at the hospital where the ED closed. However, there may be implications of reorganisation for NHS emergency care providers, with ambulance services appearing to experience a greater burden.

Future work

Understanding why effects vary between sites is necessary. It is also necessary to understand the impact on patient experience. Economic evaluation to understand the cost implications of such reorganisation is also desirable.

Review article: Emergency department models of care in the context of care quality and cost: a systematic review

To identify current ED models of care and their impact on care quality, care effectiveness, and cost. A systematic search of key health databases (Medline, CINAHL, Cochrane, EMbase) was conducted to identify literature on ED models of care. Additionally, a focused review of the contents of 11 international and national emergency medicine, nursing and health economic journals (published between 2010 and 2013) was undertaken with snowball identification of references of the most recent and relevant papers. Articles published between 1998 and 2013 in the English language were included for initial review by three of the authors. Studies in underdeveloped countries and not addressing the objectives of the present study were excluded. Relevant details were extracted from the retrieved literature, and analysed for relevance and impact. The literature was synthesised around the study's main themes. Models described within the literature mainly focused on addressing issues at the input, throughput or output stages of ED care delivery. Models often varied to account for site specific characteristics (e.g. onsite inpatient units) or to suit staffing profiles (e.g. extended scope physiotherapist), ED geographical location (e.g. metropolitan or rural site), and patient demographic profile (e.g. paediatrics, older persons, ethnicity). Only a few studies conducted cost-effectiveness analysis of service models. Although various models of delivering emergency healthcare exist, further research is required in order to make accurate and reliable assessments of their safety, clinical effectiveness and cost-effectiveness.

Scope of practice and autonomy of physician assistants in rural versus urban emergency departments

OBJECTIVES

This was a study of the scope of practice and autonomy of emergency medicine (EM) physician assistants (PAs) practicing in rural versus urban emergency departments (EDs).

METHODS

Using the American Academy of Physician Assistants (AAPA) Masterfile, a random sample of 200 U.S. EM PAs were surveyed, with oversampling of an additional 200 rural PAs. Location was classified by zip code-based rural-urban commuting area codes, and responses were compared about conditions managed, procedures performed, and physician supervision between rural versus urban groups.

RESULTS

A total of 237 responses were received from PAs in 44 U.S. states, of which (201) were valid responses (105 rural, 96 urban) from PAs currently practicing in EDs (59.3% exclusion-adjusted response rate). Compared to urban PAs, rural PAs more frequently managed cardiac arrest (67% vs. 44%), stroke (86% vs. 72%), multisystem trauma (83% vs. 70%), active labor (44% vs. 23%), and critically ill children (82% vs. 65%) in the past year. They were more likely to have performed intubation (65% vs. 44%), needle thoracostomy (21% vs. 8%), and tube thoracostomy (46% vs. 26%). Rural PAs more often reported never having a physician present in the ED (38% vs. 0%) and less often reported always having a physician present (50% vs. 98%). Rural PAs were also less likely to report that a physician evaluates more than 75% of their patients (8% vs. 18%) and more likely that a physician never evaluates all of their patients (19% vs. 7%).

CONCLUSIONS

Rural PAs reported a broader scope of practice, more autonomy, and less access to physician supervision than urban PAs.

Implementing wait-time reductions under Ontario government benchmarks (Pay-for-Results): a Cluster Randomized Trial of the Effect of a Physician-Nurse Supplementary Triage Assistance team (MDRNSTAT) on emergency department patient wait times

Background

Internationally, emergency departments are struggling with crowding and its associated morbidity, mortality, and decreased patient and health-care worker satisfaction. The objective was to evaluate the addition of a MDRNSTAT (Physician (MD)-Nurse (RN) Supplementary Team At Triage) on emergency department patient flow and quality of care.

Methods

Pragmatic cluster randomized trial. From 131 weekday shifts (8:00–14:30) during a 26-week period, we randomized 65 days (3173 visits) to the intervention cluster with a MDRNSTAT presence, and 66 days (3163 visits) to the nurse-only triage control cluster. The primary outcome was emergency department length-of-stay (EDLOS) for patients managed and discharged only by the emergency department. Secondary outcomes included EDLOS for patients initially seen by the emergency department, and subsequently consulted and admitted, patients reaching government-mandated thresholds, time to initial physician assessment, left-without being seen rate, time to investigation, and measurement of harm.

Results

The intervention’s median EDLOS for discharged, non-consulted, high acuity patients was 4:05 [95^th% CI: 3:58 to 4:15] versus 4:29 [95^th% CI: 4:19–4:38] during comparator shifts. The intervention’s median EDLOS for discharged, non-consulted, low acuity patients was 1:55 [95^th% CI: 1:48 to 2:05] versus 2:08 [95^th% CI: 2:02–2:14]. The intervention’s median physician initial assessment time was 0:55 [95^th% CI: 0:53 to 0:58] versus 1:21 [95^th% CI: 1:18 to 1:25]. The intervention’s left-without-being-seen rate was 1.5% versus 2.2% for the control (p = 0.06). The MDRNSTAT subgroup analysis resulted in significant decreases in median EDLOS for discharged, non-consulted high (4:01 [95^th% CI: 3:43–4:16]) and low acuity patients (1:10 95^th% CI: 0:58–1:19]), as well as physician initial assessment time (0:25 [95^th% CI: 0:23–0:26]). No patients returned to the emergency department after being discharged by the MDRNSTAT at triage.

Conclusions

The intervention reduced delays and left-without-being-seen rate without increased return visits or jeopardizing urgent care of severely ill patients.

Continued rise in the use of mid-level providers in US emergency departments, 1993-2009

Background

Emergency department (ED) visits in the US have risen dramatically over the past 2 decades. In order to meet the growing demand, mid-level providers (MLPs) – both physician assistants (PAs) and nurse practitioners (NPs) – were introduced into emergency care. Our objective was to test the hypothesis that MLP usage in US EDs continues to rise.

Findings

We analyzed ED data from the National Hospital Ambulatory Medical Care Survey to identify trends in ED visits seen by MLPs. We also compared MLP-only visits (defined as visits where the patient was seen by a MLP without being seen by a physician) with those seen by physicians only. During 1993 to 2009, 8.4% (95%CI, 7.6–9.2%) of all US ED visits were seen by MLPs. These summary data include marked changes in MLP utilization: PA visits rose from 2.9% to 9.9%, while NP visits rose from 1.1% to 4.7% (both P_trend < 0.001). Together, MLP visits accounted for almost 15% of 2009 ED visits and 40% of these were seen without involvement of a physician. Compared to physician only visits, those seen by MLPs only were less likely to arrive by ambulance (16% vs 6%) and be admitted (14% vs 3%).

Conclusions

Mid-level provider use is rising in US EDs. By 2009, approximately one in seven visits involved MLPs, with PAs managing twice as many visits as NPs. Although patients seen by MLPs only are generally of lower acuity, these nationally representative data confirm that MLP care extends beyond minor presentations.

International perspectives on emergency department crowding

The maturation of emergency medicine (EM) as a specialty has coincided with dramatic increases in emergency department (ED) visit rates, both in the United States and around the world. ED crowding has become a public health problem where periodic supply and demand mismatches in ED and hospital resources cause long waiting times and delays in critical treatments. ED crowding has been associated with several negative clinical outcomes, including higher complication rates and mortality. This article describes emergency care systems and the extent of crowding across 15 countries outside of the United States: Australia, Canada, Denmark, Finland, France, Germany, Hong Kong, India, Iran, Italy, The Netherlands, Saudi Arabia, Catalonia (Spain), Sweden, and the United Kingdom. The authors are local emergency care leaders with knowledge of emergency care in their particular countries. Where available, data are provided about visit patterns in each country; however, for many of these countries, no national data are available on ED visits rates or crowding. For most of the countries included, there is both objective evidence of increases in ED visit rates and ED crowding and also subjective assessments of trends toward higher crowding in the ED. ED crowding appears to be worsening in many countries despite the presence of universal health coverage. Scandinavian countries with robust systems to manage acute care outside the ED do not report crowding is a major problem. The main cause for crowding identified by many authors is the boarding of admitted patients, similar to the United States. Many hospitals in these countries have implemented operational interventions to mitigate crowding in the ED, and some countries have imposed strict limits on ED length of stay (LOS), while others have no clear plan to mitigate crowding. An understanding of the causes and potential solutions implemented in these countries can provide a lens into how to mitigate ED crowding in the United States through health policy interventions and hospital operational changes.
