Emergency medicine in Singapore: past, present, and future

What began in 1948 as a "Casualty and Outpatient Service" at the Singapore General Hospital grew into the first 24-hour emergency unit in 1964 and has since expanded to the current emergency departments of the 6 public hospitals providing acute 24-hour accident and emergency services with an annual patient load of up to 540,000. In 1984, emergency medicine was recognized as a distinct medical specialty by the Ministry of Health. Five years later, structured academic postgraduate training programs were introduced. In 1990, a specialist training committee for emergency medicine was appointed to oversee the development of advanced training in emergency medicine locally. Seven areas of subspecialization have since been identified and are in various stages of development: emergency cardiac care, emergency trauma care, emergency toxicology, prehospital emergency care, pediatric emergency medicine, disaster medicine, and observation medicine. The achievements in emergency medicine in Singapore can help to provide a model for the future development of emergency medicine in other similar environments.     

Academic emergency medicine: a national profile with and without emergency medicine residency programs.

STUDY OBJECTIVE: Formal data are lacking regarding emergency departments in academic medical centers, particularly those without an emergency medicine residency program. The Education Committee of the Society for Academic Emergency Medicine conducted a survey to define a national profile of academic emergency medicine. DESIGN: Prospective survey with telephone follow-up. SETTING: Academic medical centers. PARTICIPANTS: One hundred twenty-three academic medical centers as defined by the Association of American Medical Colleges. RESULTS: Results were obtained from 94 (78%) institutions: 27 (29%) had an emergency medicine residency program and 67 (71%) had no emergency medicine residency program. Significant differences were found between those with and without emergency medicine residency programs regarding 24-hour attending coverage (96% versus 73%), mean weekly clinical faculty hours (26 versus 33), the number of emergency medicine board-certified faculty, faculty recruitment difficulties (25% versus 75%), and the presence of a curriculum for housestaff (96% versus 38%). No significant differences were noted regarding the presence of a curriculum for medical students (78% versus 64%). Of the 67 institutions with no emergency medicine residency programs, 42% were actively planning a program, and 42% would consider future development of a program. CONCLUSION: This article provides the first comprehensive profile of emergency medicine in the Association of American Medical Colleges academic medical centers. Programs with emergency medicine residency programs provided more 24-hour attending coverage, had more emergency medicine board-certified faculty, and reported less difficulty recruiting additional faculty than institutions with no emergency medicine residency program. Both need to expand their undergraduate educational activities. Many institutions with no emergency medicine residency program are attempting to develop emergency medicine residency programs.     

Advanced training in pediatric emergency medicine in the United States, Canada, United Kingdom, and Australia: an international comparison and resources guide

Pediatric emergency medicine is an important subspecialty of pediatrics and emergency medicine. It is a well-established subspecialty in some countries and less well developed or evolving in others. We set out to develop a resource guide and document the current status of pediatric emergency medicine training across 4 countries (United States, Canada, United Kingdom, and Australia). This article also aims to provide a starting point for pediatric or emergency physicians charged with the development of pediatric emergency medicine training programs in countries without such programs.     

The aging population and future demand for emergency ambulances in Japan

Demand for emergency ambulances has been increasing in developmentally advanced countries, and in Japan demand has been increasing due to the aging population since 2008, when the total population began to decrease. However, we do not know how acceleration of the aging population relates to the demand for emergency ambulances. Thus, we estimated future demand for emergency ambulances in Japan. A regression with autocorrelated errors model was used to estimate future demand for emergency ambulance dispatches and emergency transports. In the estimation, data on emergency ambulance dispatches, emergency transports, and population data from 1963 to 2011, and an estimate of the population of Japan from 2012 to 2025 were used. The number of emergency ambulance dispatches has increased since 2008, and it is expected to continue to increase until around 2023 or 2024, when it will reach a peak of ~6.2 million per year. Similarly, the number of emergency transports is expected to continue to increase until 2022 or 2023, when it will reach a peak of ~5.3 million per year. Although we need to be careful when evaluating numbers predicted for the remote future due to methodological limitations, the findings might be useful for updating emergency medical care systems to prepare for future increases in demand.     

Implication of emergency departments in the regulation of public hospitalizations

PURPOSE: Emergency departments become a useful way to access to hospital care. Since these last years difficulties of hospitalization, mainly of the elderly, after visit to the emergency department, are on the increase. CURRENT KNOWLEDGE AND KEY POINTS: Emergency departments are an important mode of recruitment for hospital units, 4 patients to 10 are hospitalized from emergency departments. The difficulties of hospitalization starting at the emergency department are more important for the elderly. Actually, there are 2 type of hospital care, planed and non planed care. The development of observation units specific to the emergency departments allowed to resolve some of these difficulties. But they are limited by their small number of beds and the duration of hospitalization below to 36 h. Some hospitals developed polyvalent emergency short stay unit to hospitalize patients who visited emergency department without necessity to give them a specialized care. FUTURE PROSPECTS AND PROJECTS: This situation must allow us to purpose a better regulation of hospitalizations which includes emergency departments in a network system including the different hospital ways of taking care. A downstream way of care adapted to the emergency hospitalizations would be developed. This could include the emergency department, the observation unit and the emergency short stay unit in interface with internal medicine and general medicine units, geriatric unit and specialized units, all of them will be included in a town-hospital care network.     

Emergency medical care in rural America

The delivery of high-quality emergency care in a rural setting requires a conceptual framework quite different from that required in urban and suburban environments, given that available resources are limited in the rural setting. The intermittent and episodic nature of seriously ill and injured patients who present to rural emergency departments makes it difficult to plan, staff, and equip in order to provide emergency medical care at the same level seen at higher volume urban or suburban institutions. The objective of this article is to describe the distinctive nature and widely unrecognized features of emergency medicine in rural and remote areas, with a focus on clinical, workforce, and economic issues. We present recommendations for a shift in thinking and a call to action on behalf of all emergency medicine professionals that are based on a realistic assessment of the current status of emergency medicine and that are needed to develop and sustain high-quality emergency medical care in rural America.     

A survey of academic departments of emergency medicine regarding operation and clinical practice

STUDY OBJECTIVE: To survey academic departments of emergency medicine concerning their operation and clinical practice. METHODS: A survey was mailed to the chairs of all 56 academic departments of emergency medicine in the United States requesting information concerning operations and clinical activity in budget year 1997-1998 compared with 1995-1996. These results were then compared with a similar survey conducted in the fall of 1996, examining the 1995-1996 academic year compared with the 1994-1995 academic year. RESULTS: Forty-one (73%) academic departments of emergency medicine responded. For 1997-1998, compared with 1995-1996, 24 (59%) academic departments of emergency medicine reported an increase in emergency department patient volume; 10 (24%) reported a decrease. Twenty-four (51%) academic departments of emergency medicine reported an increase in ED patient severity, whereas 7 (15%) reported a decrease. Twenty-five (61%) academic departments of emergency medicine reported an increase in net clinical revenue for emergency medicine services, and 9 (22%) reported a decrease. Only 9 (22%) academic departments of emergency medicine reported other academic departments within their university/medical center aggressively directing patients away from the ED compared with 14 (30%) in the previous study. The percentage of academic departments of emergency medicine using midlevel providers remained essentially the same over time (68% versus 66%). In both studies, midlevel providers were used most commonly in a fast-track setting. Only 37% of academic departments of emergency medicine reported having an observation unit; staffing in all cases was by emergency physicians. Since the last survey, 38 (93%) academic departments of emergency medicine reported their medical center or hospital negotiating with managed care organizations to provide services. Unfortunately, only 41% of chairs were involved in these discussions. Between January 1, 1997, and the 1998 fall survey, 29% of academic departments of emergency medicine reported their university merging with another university system, and 19% reported such mergers being discussed. Similarly, between January 1, 1997, and fall 1998, 22% of academic departments of emergency medicine reported their institution merging with a private entity, whereas 16% reported ongoing discussions. CONCLUSION: Academic departments of emergency medicine have experienced some encouraging trends: an increase in ED patient volume, patient severity, and net clinical revenue during the study period. Midlevel providers continue to be used primarily in fast-track areas of EDs. An area of potential growth for academic departments of emergency medicine is observation medicine, because only one third of academic departments of emergency medicine have such a unit. Academic medical centers have experienced a significant increase in merger activity during the study period.     

Resident management of emergency department patients: is closer attending supervision needed?

STUDY OBJECTIVE: To determine the extent of supervision necessary for emergency medicine residents practicing in the emergency department. SETTING: ED of a university-affiliated tertiary care facility with an annual census of 32,000 visits. STUDY POPULATION: All ED patients presenting during study hours during a four-month period. DESIGN: A prospective study was conducted of changes made by emergency medicine attendings in the management of ED patients seen initially by second-year emergency medicine residents. Second-year emergency medicine residents presented all patients seen by them to a specified emergency medicine attending, who also interviewed and examined these patients. Initial patient care was designed by the resident and modified by the emergency medicine attending. Attending modification was recorded by the emergency medicine attending in the study log. Modifications of the residents' proposed care were designated as major (change resulted in an alteration in patient disposition, detection of unsuspected pathology, or marked revision of intended treatment); minor (change resulted in lesser modification of patient management); or no change. RESULTS: Four hundred eight patient encounters were included in the study. Sixteen patients (4%) had major modifications of their care, 134 (33%) had minor modifications, and 258 (63%) had no change. CONCLUSION: Supervision is required for all patients managed by second-year emergency medicine residents, regardless of complaints. This evaluation should include a direct patient interview and examination by the emergency medicine attending and should not be limited to a case discussion or ED record cosignature.     

Emergency endoscopy.

The need for emergency endoscopy is a matter of debate. The time interval for emergency procedures remains to be defined. Most authors propose a time span of 24 h as emergency time, while some define a period of 72 h (especially in acute pancreatitis). Several studies have shown a possible benefit for a select group of patients. Four main indications are established for emergency endoscopy: acute gastrointestinal bleeding (variceal and nonvariceal), acute biliary pancreatitis and acute cholangitis. In the case of upper gastrointestinal bleeding, emergency endoscopy enables exact diagnosis and appropriate therapy, and provides important prognostic information. There is some evidence that emergent endoscopic injection therapy improves clinical outcome and reduces mortality in patients with acute ulcer bleeding. Patients do not benefit if endoscopy is performed only as a diagnostic procedure. Controversial results were published recently for emergency endoscopy in acute biliary pancreatitis. There is good evidence that emergency endoscopic retrograde cholangiopancreatography is helpful in patients with severe pancreatitis and stone impaction if performed within the first 24 h after onset of symptoms. However, emergency endoscopic retrograde cholangiopancreatography is not beneficial for patients with mild pancreatitis if performed later than 72 h (or 24 h) after onset of symptoms. There is a limited number of well established evidence-based indications for emergency endoscopy. Some other indications are still a matter of debate, and controversial opinions have been published.     

Diabetes management by either telemedicine or clinic visit improved glycemic control during the coronavirus disease 2019 pandemic state of emergency in Japan

The purpose of this retrospective cohort study at a Tokyo diabetes clinic was to evaluate the effect of telemedicine and clinic visit on glycated hemoglobin (HbA1c) during the coronavirus disease 2019 state of emergency. The effect of telemedicine and clinic visit during the emergency period on the post‐emergency measured HbA1c was evaluated by multiple regression models and logistic regression models adjusted for age, sex, type of diabetes, pre‐emergency HbA1c and body mass index, and body mass index change during the emergency period. Among 2,727 patients who visited the clinic before and after the emergency period, the interval between clinic visits during the emergency period was significantly associated with HbA1c improvement. Telemedicine and clinic visit were independently associated with HbA1c improvement when pre‐emergency HbA1c was ≥7%. In conclusion, clinic visit and telemedicine during the coronavirus disease 2019 emergency period were both independently effective in HbA1c improvement in Japanese diabetes patients who had insufficient HbA1c control.

Frequent use of the emergency department among persons with systemic lupus erythematosus

Objective

To describe characteristics of systemic lupus erythematosus (SLE) patients who are frequent users of the emergency department and to identify predictors of frequent emergency department use.

Methods

Data for this study were derived from the University of California, San Francisco Lupus Outcomes Study, a large cohort of persons with SLE who undergo annual structured interviews. Participants were categorized into 1 of 3 levels of emergency department utilization: nonusers (no visits in the preceding year), occasional users, (1–2 visits), and frequent users (≥3 visits). We compared characteristics of the 3 groups and determined predictors of frequent emergency department use (≥3 visits) using multivariate logistic regression, adjusting for a variety of potential confounding covariates.

Results

Of 807 study participants, 499 (62%) had no emergency department visits; 230 (28%) had occasional emergency department visits (1–2 visits); and 78 (10%) had frequent (≥3 visits) emergency department visits. Frequent users were younger, less likely to be employed, and less likely to have completed college. They also had greater disease activity, worse general health status, and more depressive symptoms. Frequent emergency department users were more likely to have Medicaid as their principal insurance. In multivariate logistic regression, older age predicted a lower likelihood of frequent emergency department visits, whereas greater disease activity and having Medicaid insurance predicted a higher likelihood of frequent emergency department visits.

Conclusion

In persons with SLE, greater disease activity and Medicaid insurance are associated with more frequent emergency department use.     

The impact of follow-up physician visits on emergency readmissions for patients with asthma and chronic obstructive pulmonary disease: a population-based study

PURPOSE: To examine the relation between follow-up office visits after emergency discharge and the risk of emergency readmissions in patients with asthma or chronic obstructive pulmonary disease (COPD). SUBJECTS AND METHODS: We used population-based data to identify all patients in Alberta, Canada, who had at least one emergency visit for asthma or COPD between April 1, 1996, and March 31, 1997 (N = 25 256). A Cox proportional hazards model was used to estimate the adjusted relative risk (RR) of a repeat visit to an emergency department within 90 days of an initial emergency visit in patients who did or did not have an office follow-up within the first 30 days. RESULTS: There were 7829 patients (31%) who had an office visit during the 30 days after their initial emergency encounter. Follow-up visits were associated with a significant reduction in the 90-day risk of an emergency readmission (RR = 0.79; 95% confidence interval [CI]: 0.73 to 0.86). Sensitivity analyses showed that a follow-up visit was inversely associated with a repeat emergency visit after adjusting for age, sex, area of residence, and income. CONCLUSION: Although these data should be interpreted with caution because of missing information on factors such as quality of care, they suggest that follow-up office visits are effective in reducing early relapses in patients who have been recently treated in emergency departments for asthma or COPD.     

A pediatric curriculum for emergency medicine training programs

Surveys of current training show that many areas of pediatric emergency medicine are not taught in emergency medicine residencies. Furthermore, published recommendations for minimum pediatric core content in emergency medicine are scant and conflicting. To address this issue we have compiled from a variety of sources a detailed pediatric emergencies curriculum for emergency residency training. This curriculum is complete, and yet may be carried out with currently available resources.

After thrombolytic therapy: angiography, angioplasty, or surgery?

Thrombolytic therapy has been found to improve the prognosis of selected patients with acute myocardial infarction. Many investigators advocate that combined emergency coronary angiography and percutaneous transluminal coronary angioplasty be performed immediately after thrombolytic therapy. Emergency angiography documents the anatomic extent of coronary artery disease, shows whether reperfusion has occurred, and indicates whether emergency angioplasty is necessary. In this setting, emergency catheterization without angioplasty is associated with relatively little additional risk. However, a number of prospective trials have compared emergency angioplasty to more conservative treatment strategies, and emergency angioplasty has been not found to offer any advantage in terms of improved prognosis or preservation of left ventricular function. Therefore, it is probable that most patients with evolving Q-wave myocardial infarction are best treated with conservative strategies after initial thrombolytic therapy, although there may still be a role for emergency angioplasty in a relatively small subset who present with evolving myocardial infarction and severely depressed left ventricular function. Emergency coronary artery bypass surgery also appears to have a limited role in patients treated with thrombolytic therapy. Nevertheless, in occasional patients with a poor prognosis at hospital presentation, in whom thrombolytic therapy and emergency angioplasty have failed or are contraindicated, prompt emergency coronary artery bypass grafting may salvage the ischemic myocardium and improve the prognosis.     

Scientific Publication in Emergency Medicine: Imprint on the Future

Intensified research efforts in emergency medicine have resulted in a unique body of knowledge based on investigations involving emergency patients and conducted by emergency medicine researchers. The success and effectiveness of emergency medicine publications in the future rely on adherence to rigorous standards for peer review and editorial evaluation, introduction of value-added innovations, creative applications for electronic publication of scientific materials, and an unyielding commitment to quality and integrity.

World Health Assembly Resolution 60.22 and its importance as a health care policy tool for improving emergency care access and availability globally

The recent adoption of World Health Assembly Resolution 60.22, titled "Health Systems: Emergency Care Systems," has established an important health care policy tool for improving emergency care access and availability globally. The resolution highlights the role that strengthened emergency care systems can play in reducing the increasing burden of disease from acute illness and injury in populations across the socioeconomic spectrum and calls on governments and the World Health Organization to take specific and concrete actions to make this happen. This resolution constitutes recognition by the World Health Assembly of the growing public health role of emergency care systems and is the highest level of international attention ever devoted to emergency care systems worldwide. Emergency care systems for secondary prevention of acute illnesses and injury remain inadequately developed in many low- and middle-income countries, despite evidence that basic strategies for improving emergency care systems can reduce preventable mortality and morbidity and can in many cases also be cost-effective. Emergency care providers and their professional organizations have used their comprehensive expertise to strengthen emergency care systems worldwide through the development of tools for emergency medicine education, systems assessment, quality improvement, and evidence-based clinical practice. World Health Assembly 60.22 represents a unique opportunity for emergency care providers and other advocates for improved emergency care to engage with national and local health care officials and policymakers, as well as with the World Health Organization, and leverage the expertise within the international emergency medicine community to make substantial improvements in emergency care delivery in places where it is most needed.
