A study of the workforce in Emergency Medicine in Israel: 2003

Emergency Medicine (EM) was officially recognized as a specialty in Israel in 1999. In 2003 the first nine Israeli trained emergency physicians (EPs) were certified. This survey was undertaken to assess current staffing of Emergency Departments (ED) in Israel and to attempt to estimate future staffing needs for EPs. A survey was sent to all ED directors at general hospitals in Israel. We asked questions relating to staffing by number of physicians, type and level of training, and differential staffing by time of the day and week. In addition, we inquired as to the census, structure, hospital resources available, and size of the ED. Twenty-four of 25 (96%) EDs responded. There were 59 EM specialists registered in Israel; there were 37 EM residents. EDs reported a total of 1,872,500 visits annually. Emergency care is otherwise given by specialists and residents in other fields, and non-specialist physicians. At large hospitals there is an average of 2.5 EM specialists during daytime hours, and another four specialists of other types on duty. During the night in large hospitals, there is an average of <1 specialist of any kind (typically not EM) on duty. In most EDs, care is turned over to non-specialists (residents and others) during evenings and nights. The recognition of the need for Emergency Medicine as a specialty in Israel has not as yet translated into care of emergencies by EPs for most patients. To adequately staff EDs with physicians trained in EM, an emphasis needs to be placed on increasing EM staff and resident positions. The need seems most acute in medium-sized hospitals and during off hours and weekends.     

Assessment of Emergency Physician Workforce Needs in the United States, 2005

Objectives: The objective was to estimate emergency physician (EP) workforce needs, taking into account the diversity of U.S. emergency departments (EDs) and various projections of EP supply and demand. Methods: The 2005 National ED Inventory‐USA ( http://www.emnet‐usa.org/ ) provided annual visit volumes for 4,828 U.S. EDs. The authors calculated annual supply based on existing emergency medicine (EM) board‐certified EPs, adding newly board‐certified EPs, and subtracting board‐certified EPs who died or retired. Demand was estimated at each ED by dividing the number of visits by the average EP volume (based on 2.8 patients/hour, 40 hours/week, and 34% nonclinical time). The models assumed that at least 1 EP should be present 24/7 in each ED, which would require at least 5.35 full‐time equivalents (FTEs) per ED. Based on annual EP attrition estimates, results for best‐case, worst‐case, and intermediate scenarios were calculated. Results: In 2005, there were approximately 22,000 EM board‐certified EPs, but 40,030 EPs would be needed to staff all 4,828 EDs (55% of demand met). A total of 2,492 (52%) EDs had a visit volume that required the minimum number (5.35) FTEs, of which 47% were rural. In the unrealistic (no attrition), best‐case scenario, it would take until 2019 to staff all EDs with board‐certified EPs. In the worst‐case scenario (12% attrition), supply would never meet demand. Our intermediate scenario (2.5% attrition) suggested that board‐certified EPs would satisfy workforce needs in 2038. Conclusions: Supply of EM residency‐trained, board‐certified EPs is not likely to meet demand in the near future. Alternative EP staffing arrangements merit further consideration.     

Workforce Projections for Emergency Medicine: How Many Emergency Physicians Does the United States Need?

Objective: To mathematically model the supply of and demand for emergency physicians (EPs) under different workforce conditions.
Methods: A computer spreadsheet model was used to project annual EP workforce supply and demand through the year 2035. The mathematical equations used were: supply = number of EPs at the beginning of the year plus annual residency graduates minus annual attrition; demand = 5 full-time equivalent positions/ED X the number of hospital EDs. The demand was empirically varied to account for ED census variation, administrative and teaching responsibilities, and the availability of physician extenders. A variety of possible scenarios were tested. These projections make the assumption that emergency medicine (EM) residency graduates will preferentially fill clinical positions currently filled by EPs without EM board certification.
Results: Under most of the scenarios tested, there will be a large deficit of EM board-certified EPs well into the next century. Even in scenarios involving a decreasing "demand" for EPs (e.g., in the setting of hospital closures or the training of physician extenders), a significant deficit will remain for at least several decades. Conclusions: The number of EM residency positions should not be decreased during any restructuring of the U.S. health care system. EM is likely to remain a specialty in which the supply of board-certified EPs will not meet the demand, even at present levels of EM residency output, for the next several decades.     

Analysis of Factors Affecting U.S. Emergency Physician Workforce Projections

Objectives: To use existing data sources to refine prior estimates of the U.S. emergency medicine (EM) workforce and to estimate effects of proposed changes in the U.S. health care system on the EM workforce. Methods: Relevant data were extracted from the American College of Emergency Physicians (ACEP) 1995 Membership Activity Report, the American Medical Association (AMA) publication "1995/96 Physician Characteristics and Distribution in the U.S.," the American Hospital Association (AHA) 1994 hospital directory, a written survey of each state's medical licensing board and state medical society, and the American Board of Emergency Medicine (ABEM) annual activity report for 1995. These data were used to project workforce supply and demand estimates applicable to workforce models.
Results: None of the available information sources had complete data on the number and distribution of emergency physicians (EPs) currently practicing in the United States. Extrapolating the limited reliable statewide EP numbers to make nationwide projections reveals a shortage of EPs needed to fully staff the nation's existing EDs. At least 22 states had an average ratio of <5 EPs per existing ED. Additional national projections incorporating a decreasing number of U.S. EDs indicate that the current annual number of EM residency graduates will not eliminate the deficit of EPs for at least several decades, given that projected numbers of retiring EPs annually will soon equal the total annual EM residency graduate production. Conclusions: Although the current data on EPs in practice in the United States are incomplete, the authors project a relative shortage of EPs. More accurate and complete information on the numbers and distribution of EPs in America is needed to improve workforce projections.     

Supply and Demand of Board-certified Emergency Physicians by U.S. State, 2005

Objectives:  The objective was to estimate the emergency medicine (EM) board-certified emergency physician (EP) workforce supply and demand by U.S. state.
Methods:  The 2005 National Emergency Department Inventories-USA provided annual visit volumes for U.S. emergency departments (EDs). We estimated full-time equivalent (FTE) EP demand at each ED by dividing the actual number of visits by the estimated average EP visit volume (3,548 visits/year) and then summing FTEs by state. Our model assumed that at least one EP should be present 24/7 in each ED. The number of EM board-certified EPs per state was provided by the American Board of Medical Specialties (American Board of Emergency Medicine, American Board of Pediatrics) and the American Osteopathic Board of Emergency Medicine. We used U.S. Census Bureau civilian population estimates to calculate EP population density by state.
Results:  The supply of EM board-certified EPs was 58% of required FTEs to staff all EDs nationally and ranged from 10% in South Dakota to 104% in Hawai'i (i.e., there were more EPs than the estimated need). Texas and Florida had the largest absolute shortages of EM board-certified EPs (2,069 and 1,146, respectively). The number of EM board-certified EPs per 100,000 U.S. civilian population ranged from 3.6 in South Dakota to 13.8 in Washington, DC. States with a higher population density of EM board-certified EPs had higher percent high school graduates and a lower percent rural population and whites.
Conclusions:  The supply and demand of EM board-certified EPs varies by state. Only one state had an adequate supply of EM board-certified EPs to fully staff its EDs.     

Information Technology in Emergency Medicine Residency–Affiliated Emergency Departments

OBJECTIVES: To describe acquisition and implementation of information technology (IT) in U.S. emergency medicine (EM) residency-affiliated emergency departments (EDs), including automatic medication error checking. METHODS: This was a survey of all U.S. EM residencies active in September 2000. Respondents specified whether specific IT tools had been "acquired" and "implemented fully." EDs were categorized according to primary versus affiliated training site, trauma level, and census. Numbers of "yes" responses were compared according to ED type (Kruskal-Wallis test, p < or = 0.05 significant). RESULTS: Of 121 residency programs, data were obtained from 93 (77%) for a total of 149 EDs. The percentages of EDs that reported full implementation for each technology are as follows: medication error checking, 7%; medication order entry, 18%; nonmedication orders, 7%; clinical documentation, 21%; old electrocardiograms, 62%; laboratory results, 84%; radiography order entry, 62%; image retrieval, 29%; radiologists' interpretations, 67%; cardiology reports, 62%; pathology reports, 70%; surgical reports/dictations, 60%; triage, 34%; tracking, 46%; electronic reference materials, 56%; registration, 84%; accounts, 72%; patient management software package, 20%; voice recognition, 7%. Trauma centers reported more IT tools than nontrauma centers (p = 0.01), and primary training sites reported fewer IT tools than affiliated EDs (p = 0.027). CONCLUSIONS: Incorporation of IT is not uniform in EDs where EM residents train. Acquisition of effective IT tools varies, and implementation lags behind acquisition. Fully implemented IT for medication error checking was reported in 7% of EDs; an additional 12% had acquired IT without implementing it fully.     

Airway management practices in emergency medicine residencies

The Core Content for Emergency Medicine (EM) recommends that all emergency physicians be trained to manage the airway, including administering paralytic agents for endotracheal intubation. This study analyzed compliance with the recommendations by reviewing airway management practices at EM residencies. All 96 EM residency directors were sent a 10-item survey characterizing airway management practices at residency-affiliated emergency departments (EDs). The 91 respondents (95%) represented residencies with 120 affiliated hospitals. Paralytic agents routinely were used during intubations in 114 of the EDs (95%). Forty-nine of the EDs (41%) never requested an anesthesiologist for intubations, and 8 EDs (7%) mandated anesthesiology presence during paralytic agent administration. The Department of Anesthesiology never performed quality assurance (QA) evaluations in at least 64 EDs (53%). The Department of Emergency Medicine performed QA checks less than two thirds of the time in at least 44 EDs (36%). The majority of EM residencies are complying with the Core Content recommendations by actively performing intubations using paralytic agents. Anesthesiologists are infrequently consulted in residency-affiliated EDs. Quality assurance of ED intubations is not rigorously monitored by emergency and anesthesiology departments.     

The Rate of Clinically Significant Plain Radiograph Misinterpretation by Faculty in an Emergency Medicine Residency Program

Objective: To estimate the rate of clinically significant discrepancies between radiograph interpretations by attending radiologists and emergency medicine (EM) faculty in 2 academic EDs, using a unique scoring system.
Methods: A retrospective comparison of radiographic agreement between EM and radiology faculty members was performed. All plain films initially interpreted by EM faculty or by EM residents with immediate rein-terpretation by EM faculty were subsequently reviewed by attending radiologists. All discrepancies between these readings were reported to the ED on the following day for review by an EM faculty member (usually different from the initial EM faculty reader) who determined the need for treatment or follow-up changes. A secondary chart review by a quality assurance faculty member determined whether radiographic findings not noted on the x-ray log were present on the ED record. All discrepancies from February to June 1994 were reviewed. A severity score was assigned based on the following criteria. Q-0: There was no change in treatment or follow-up; or the initial interpretation by EM faculty was validated by repeat or additional views. Q-1: Discrepancy is minor. Q-2: Discrepancy is significant, with potential for injury or bad outcome. 4–3: Discrepancy is significant, with actual injury or bad outcome.
Results: Of 14,046 radiographic studies eligible for enrollment, there were 134 discrepancies (0.95%). Only 28 cases (0.2%) were found to be clinically significant. Of these, 25 were scored Q-1, 3 were scored Q-2, and 0 were scored 4–3. These clinically significant discrepancy rates were highest for the finger, skull, elbow, hand, and lumbar spine.
Conclusion: Emergency medicine faculty provide highly accurate rates of plain radiograph interpretation, particularly when adjusted for clinical significance and actual impact on patient care.     

Application of scoring systems with point-of-care ultrasonography for bedside diagnosis of appendicitis

BACKGROUND: Appendicitis is a common disease requiring surgery. Bedside ultrasound (BUS) is a core technique for emergency medicine (EM). The Alvarado score is a well-studied diagnostic tool for appendicitis. This study aimed to investigate the relationship between patients' symptoms, Alvarado score and ultrasound (US) findings, as performed by emergency physicians (EPs) and radiologists, of patients with suspected appendicitis.METHODS: Three EM specialists underwent the BUS course and core course for appendicitis assessment. Patients suspected of having appendicitis were selected and their Alvarado and modified (m) Alvarado scores calculated. The specialists performed the BUS. Then, patients were given a formal US and surgery consultation if necessary. Preliminary diagnoses, admission or discharge from the emergency department (ED) and final diagnosis were documented. The patients were also followed up after discharge from the hospital.RESULTS: The determined cut-off value was 2 for Alvarado and 3 for mAlvarado scores. The sensitivities of the two scores were 100%. Each score was used to rule out appendicitis. The results of EP-performed BUS were as follows: accuracy 70%, sensitivity 0.733, specificity 0.673, + LR 2.24, and - LR 0.40 (95%CI). Radiologists were better than EPs at diagnosing appendicitis and radiologists and EPs were equally strong at ruling out appendicitis by US. When US was combined with Alvarado and mAlvarado scores, EP US+Alvarado/mAlvarado scores ≤3 and radiology US+Alvarado/mAlvarado scores ≤4 perfectly ruled out appendicitis.CONCLUSION: BUS performed by EPs is moderately useful in detecting appendicitis. Combined with scoring systems, BUS may be a perfect tool for ruling out decisions in EDs.     

Need for Standardized Sign-out in the Emergency Department: A Survey of Emergency Medicine Residency and Pediatric Emergency Medicine Fellowship Program Directors

Objectives
To determine the existing patterns of sign-out processes prevalent in emergency departments (EDs) nationwide. In addition, to assess whether training programs provide specific guidance to their trainees regarding sign-outs and attitudes of emergency medicine (EM) residency and pediatric EM fellowship program directors toward the need for the development of standardized guidelines relating to sign-outs.
Methods
A Web-based survey of training program directors of each Accreditation Council for Graduate Medical Education (ACGME)–accredited EM residency and pediatric EM fellowship program was conducted in March 2006.
Results
Overall, 185 (61.1%) program directors responded to the survey. One hundred thirty-six (73.5%) program directors reported that sign-outs at change of shift occurred in a common area within the ED, and 79 (42.7%) respondents indicated combined sign-outs in the presence of both attending and resident physicians. A majority of the programs, 119 (89.5%), stated that there was no uniform written policy regarding patient sign-out in their ED. Half (50.3%) of all those surveyed reported that physicians sign out patient details "verbally only," and 79 (42.9%) noted that transfer of attending responsibility was "rarely documented." Only 34 (25.6%) programs affirmed that they had formal didactic sessions focused on sign-outs. A majority (71.6%) of program directors surveyed agreed that specific practice parameters regarding transfer of care in the ED would improve patient care; 80 (72.3%) agreed that a standardized sign-out system in the ED would improve communication and reduce medical error.
Conclusions
There is wide variation in the sign-out processes followed by different EDs. A majority of those surveyed expressed the need for standardized sign-out systems.     

Accuracy of radiographic readings in the emergency department

Objectives

A review of radiology discrepancies of emergency department (ED) radiograph interpretations was undertaken to examine the types of error made by emergency physicians (EPs).

Methods

An ED quality assurance database containing all radiology discrepancies between the EP and radiology from June 1996 to May 2005 was reviewed. The discrepancies were categorized as bone, chest (CXR), and abdomen (AXR) radiographs and examined to identify abnormalities missed by EPs.

Results

During the study period, the ED ordered approximately 151?693 radiographs. Of the total, 4605 studies were identified by radiology as having a total of 5308 abnormalities discordant from the EP interpretation. Three hundred fifty-nine of these abnormalities were not confirmed by the radiologist (false positive). The remainder of the discordant studies represented abnormalities identified by the radiologist and missed by the EP (false negatives). Of these false-negative studies, 1954 bone radiographs (2.4% of bone x-rays ordered) had missed findings with 2050 abnormalities; the most common missed findings were fractures and dislocations. Of the 220 AXRs (3.7% of AXRs ordered) with missed findings, 240 abnormalities were missed; the most common of these was bowel obstruction. Of the 2431 CXRs (3.8% of CXRs ordered), 2659 abnormalities were missed; the most common were air-space disease and pulmonary nodules. The rate of discrepancies potentially needing emergent change in management based solely on a radiographic discrepancy was 85 of 151?693 x-rays (0.056%).

Conclusions

Approximately 3% of radiographs interpreted by EPs are subsequently given a discrepant interpretation by the radiology attending. The most commonly missed findings included fractures, dislocations, air-space disease, and pulmonary nodules. Continuing education should focus on these areas to attempt to further reduce this error rate.     

Resident Service Hours in Emergency Medicine

Objective: The number of hours worked by residents in all specialties has become a controversial issue. Residents often are expected to competently conduct patient care activities and to take educational advantage of clinical experiences in spite of frequent fatigue and sleep deprivation. This survey of residency directors was designed to assess the scheduled clinical time for emergency medicine (EM) residents. Methods: A 13-question survey dealing with time commitments of EM residents was sent to the residency directors of all accredited EM residency programs in the United States in the fall of 1991. Residency directors were asked to indicate the number of shifts, hours, and days off per week; and the number of night shifts and weekend days off per month for each postgraduate year of residency training (PGY1-PGY4). Directors also were asked whether shifts were scheduled randomly or predictably with progression from days to nights with time off after nights. Results: Seventy of 71 (98.6% response rate) residency directors responded. Residents were scheduled for an average of 49.1 hours per week. Scheduled hours decreased from an average of 51.9 at the PGY1 level to an average of 44.5 at the PGY4 level. A similar progression with year of training was noted for scheduled night shifts/ month, days off/week, and weekend days off/month. A PGY1 trainee averaged 7.0 night shifts/month, 1.9 days off/week, and 3.0 weekend days off/month; while a PGY4 trainee averaged 5.3, 2.4, and 3.2, respectively. Only 40% of the directors reported predictable scheduling progressing from days to nights. Conclusion: Emergency medicine resident schedules, as reported by residency directors, fall well within current specialty-specific requirements and compare favorably with the reported numbers for other specialties. However, because large ranges in scheduling parameters were reported, the data may be of value to residency directors, residents, and prospective residents. Most programs did not report a predictable schedule progression of shifts.     

The Demands of 24/7 Coverage: Using Faculty Perceptions to Measure Fairness of the Schedule

OBJECTIVES: Ensuring fair, equitable scheduling of faculty who work 24-hour, 7-day-per-week (24/7) clinical coverage is a challenge for academic emergency medicine (EM). Because most emergency department care is at personally valuable times (evenings, weekends, nights), optimizing clinical work is essential for the academic mission. To evaluate schedule fairness, the authors developed objective criteria for stress of the schedule, modified the schedule to improve equality, and evaluated faculty perceptions. They hypothesized that improved equality would increase faculty satisfaction. METHODS: Perceived stress was measured for types of clinical shifts. The seven daily shifts were classified as weekday, weekend, or holiday (plus one unique teaching-conference coverage shift). Faculty assigned perceived stress to shifts (ShiftStress) utilizing visual analog scales (VAS). Faculty schedules were measured (ShiftScores) for two years (1998-1999), and ShiftScore distribution of faculty was determined quarterly. Schedules were modified (1999) to reduce interindividual ShiftScore standard deviation (SD). The survey was performed pre- and postintervention. RESULTS: Preintervention, 26 faculty (100% of eligible) assigned VAS to 22 shifts. Increased stress was perceived in progression (weekday data, 0-10 scale) from day to evening to night (2.07, 5.00, 6.67, respectively) and from weekday to weekend to holiday (day-shift data, 2.07, 4.93, 5.87). The intervention reduced interindividual ShiftScore SD by 21%. Postintervention survey revealed no change in perceived equality or satisfaction. CONCLUSIONS: Faculty perceived no improvement despite scheduling modifications that improved equality of the schedule and provided objective measures. Other predictors of stress, fairness, and satisfaction with the demanding clinical schedule must be identified to ensure the success of EM faculty.     

Color doppler in the diagnosis of ectopic pregnancy in the emergency department: is there anything beyond a mass and fluid?

Pregnant patients with first trimester complications are a common presentation in many Emergency Departments (EDs). The burden of disproving the existence of an ectopic pregnancy falls on the Emergency Physician (EP). This may be a difficult task depending on the availability of specialty backup and radiologic services. For more than a decade EPs have documented use of bedside ultrasonography for ruling out cases of ectopic pregnancy. Now, with the entry of newer technology into many emergency ultrasound programs, color Doppler is available to an increasing number of EPs. Color Doppler is used as an adjunct to diagnosing ectopic pregnancy by both radiology and gynecology practitioners and can at times provide critical information regarding early pregnancy. Presented are three cases of ectopic pregnancy diagnosed on the basis of abnormal color Doppler findings, and a discussion of the technique.     

The Emergency Medicine Workforce: Shortage Resolving,Future Surplus Expected

IntroductionThe emergency medicine (EM) workforce has been growing at a rapid rate, fueled by a large increase in the number of EM residency programs and growth in the number of Advanced Practice Providers (APPs).ObjectivesTo review current available data on patient volumes and characteristics, the overall physician workforce, the current emergency physician (EP) workforce, and to project emergency physician staffing needs into the future.MethodsData was obtained through review of the current medical literature, reports from certifying organizations and professional societies, Web searches for alternative sources, and published governmental data.ResultsWe conservatively estimate the demand for emergency clinicians to grow by ∼1.8% per year. The actual demand for EPs will likely be lower, considering the higher growth rates seen by APPs, likely offsetting the need for increasing numbers of EPs. We estimate the overall supply of board-certified or board-eligible EPs to increase by at least 4% in the near-term, which includes losses due to attrition. In light of this, we conservatively estimate the supply of board-certified or eligible EPs should exceed demand by at least 2.2% per year. In the intermediate term, it is possible that the supply of board-certified or eligible EPs could exceed demand by 3% or more per year. Using 2.2% growth, we estimate that the number of board-certified or board-eligible EPs should meet the anticipated demand for EPs as early as the start of 2021. Furthermore, extrapolating current trends, we anticipate the EP workforce could be 20–30% oversupplied by 2030.ConclusionsHistorically, there has been a significant shortage of EPs. We project that this shortage may resolve quickly, and there is the potential for a significant oversupply in the future.     

Agreement in the Interpretation of Extremity Radiographs of Injured Children and Adolescents

Objectives: To measure agreement beyond chance (kappa) for comparison interpretations of extremity radiographs by pediatric radiologists and emergency physicians (EPs) and to identify factors associated with disagreement.
Methods: A random sample of 205 radiographs was selected from 1,016 patients having x-rays of their extremities in the emergency and radiology departments of a tertiary care pediatric hospital. Interpretations by the "official" reporting pediatric radiologist (ORPR), the treating EP, and a pediatric radiologist blinded to all clinical information (BPR) were compared for three categories: "abnormal" (one or more of fracture, dislocation, or effusion); "possibly abnormal"; and "normal."
Results: The overall weighted kappa (K,) for the ORPRs and the EPs was 0.55. For fractures alone, the K, for the ORPRs vs the EPs was 0.77; and for effusions alone, the value was 0.34. The K, for the ORPRs vs the BPR was 0.63 (range 0.43–0.83 for individual ORPRs). The main areas of disagreement were in the identification of joint effusions and of nondisplaced fractures of the phalanges, elbow joint. tarsals, or metatarsals.
Conclusions: There is good agreement between EPs and pediatric radiologists in interpreting extremity radiographs of injured children and adolescents. Disagreement occurs mainly for effusions or minor fractures and for the elbow region. Because of the importance of recognizing abnormalities in this region, an educational intervention to improve this area of deficiency is recommended.     

Ultrasound interpretation of hydronephrosis is improved by a brief educational intervention

Nineteen emergency medicine (EM) physicians (14 residents and 3 attendings) from an EM residency program which teaches ultrasound as part of the curriculum, were asked to rate 40 ultrasound scans showing different degrees of kidney hydronephrosis, first solely on the basis of their prior knowledge and experience. One week later, after a brief 15 minute lecture on a new objective method to read degrees of hydronephrosis, the same EM physicians were again asked to rate the 40 ultrasounds. One month later, to assess retention of the method, the same physicians were asked to read the same scans using the objective method presented 1 month prior. The three readings were compared with each other, and then each with a gold standard established for the study. Agreement of the group regarding scan interpretation improved and was maintained after the educational intervention (multirater kappa + .19, .32, and .32 for the three tests administered). When the differences between each week's readings and the gold standard were assessed, differences decreased with each successive test, and were statistically significant with the third test (P = .029). We conclude that our brief educational intervention improves agreement among physicians in readings of ultrasound scans and also significantly increases accuracy in readings when compared with a gold standard.
