Analysis of factors influencing length of stay in the emergency department

OBJECTIVES Length of stay (LOS) is a key measure of emergency department (ED) throughput and a marker of overcrowding. Time studies that assess key ED processes will help clarify the causes of patient care delays and prolonged LOS. The objectives of this study were to identify and quantify the principal ED patient care time intervals, and to measure the impact of important service processes (laboratory testing, imaging and consultation) on LOS for patients in different triage levels. METHODS In this retrospective review, conducted at a large urban tertiary care teaching hospital and trauma centre, investigators reviewed the records of 1047 consecutive patients treated during a continuous 7-day period in January 1999. Key data were recorded, including patient characteristics, ED process times, tests performed, consultations and overall ED LOS. Of the 1047 patient records, 153 (14.6%) were excluded from detailed analysis because of incomplete documentation. Process times were determined and stratified by triage level, using the Canadian Emergency Department Triage and Acuity Scale (CTAS). Multiple linear regression analysis was performed to determine which factors were most strongly associated with prolonged LOS. RESULTS Patients in intermediate triage Levels III and IV generally had the longest waiting times to nurse and physician assessment, and the longest ED lengths of stay. CTAS triage levels predicted laboratory and imaging utilization as well as consultation rate. The use of diagnostic imaging and laboratory tests was associated with longer LOS, varying with the specific tests ordered. Specialty consultation was also associated with prolonged LOS, and this effect was highly variable depending on the service consulted. CONCLUSIONS Triage level, investigations and consultations are important independent variables that influence ED LOS. Future research is necessary to determine how these and other factors can be incorporated into a model for predicting LOS. Improved information systems will facilitate similar ED time studies to assess key processes, lengths of stay and clinical efficiency.

Brain abscess in patients with hereditary hemorrhagic telangiectasia: Case report and literature review

Hereditary hemorrhagic telangiectasia (HHT), or Osler-Weber-Rendu disease, affects multiple organ systems. Brain abscess is a potential complication, and this disease carries a high mortality. In the setting of HHT the abscess most likely results from paradoxical septic emboli or bacterial seeding of an ischemic portion of the brain after paradoxical sterile emboli. Brain abscess is the diagnosis that must be ruled out in patients with HHT presenting with new onset neurologic symptoms. The clinician can be misled by seemingly benign and nonspecific symptoms, signs, and laboratory test results. Appropriate diagnostic imaging with computed tomography or magnetic resonance imaging of the head is mandatory. We present a case of brain abscess in a patient with HHT presenting to the Emergency Department. The review of the literature deals with the pathophysiology and manifestations of HHT with particular focus on the pathologic and clinical features, and management of cerebral abscess in this setting. Differences between patients with brain abscess with or without HHT are highlighted.

Acute gastric volvulus: case report and review of the literature

Gastric volvulus is a rare but potentially life-threatening cause of upper gastrointestinal obstruction. Emergency physicians must maintain a high index of suspicion in patients who present with signs and symptoms suggesting foregut occlusion. We report an illustrative case and review the pathogenesis, classification, diagnosis and treatment of this rare entity.

Impact of a nurse practitioner on patient care in a Canadian emergency department.

OBJECTIVE Our objective was to determine whether the addition of a broad-scope nurse practitioner (NP) would improve emergency department (ED) wait times, ED lengths of stay (LOS) and left-without-treatment (LWOT) rates. We hypothesized that the addition of a broad-scope NP during weekday ED shifts would result in shorter patient wait times, reduced LOS and fewer patients leaving the ED without treatment. METHODS This prospective observational study was conducted in a busy urban free-standing community ED. Intervention shifts, with NP coverage, were compared with control shifts (similar shifts with emergency physicians [EPs] working independently). Primary outcomes included patient wait times, ED LOS and LWOT rates. Patient demographics, triage category, the provider seen, the time to provider and ED LOS were captured using an electronic database. RESULTS The addition of an NP was associated with a 12% increase in patient volume per shift and a 7-minute reduction in mean wait times for low-acuity patients. However, overall patient wait times and ED LOS did not differ between intervention and control shifts. During intervention shifts, EPs saw a smaller proportion of low-acuity patients and there was a trend toward a lower proportion of LWOT patients (11.9% v. 13.7%, p = 0.10). CONCLUSION Adding a broad-scope NP to the ED staff may lower the proportion of patients who leave without treatment, reduce the proportion of low-acuity patients seen by EPs and expedite throughput for a subgroup of less urgent patients. However, it did not reduce overall wait times or ED LOS in this setting.

Emergency department diagnosis and treatment of traumatic hip dislocations in children under the age of 7 years: a 10-year review.

Background and aims Traumatic hip dislocations (THD) are uncommon in children. They constitute true emergencies because unrecognised THD leads to avascular necrosis (AVN) of the femoral head. This review presents the evidence for best practice for the diagnosis and treatment of THD in the emergency department (ED) of children under the age of 7 years. Methods Searches for the period 2002–2012 were performed in PubMED, Cochrane database, EMBASE, Google Scholar and hand search. Results Twenty-five case reports and case series articles were identified, 53 described children with acute and 23 with neglected THD. Overall, 42 (55%) were male and 73 (96%) sustained a posterior dislocation. Forty-eight (63%) had THD following a low-energy trauma. Eight (11%) reported associated injuries. Twenty-one (39.6%) acute dislocations were reduced in the ED without complications. AVN was identified in 3 (5.7%) children, who underwent reduction ≥10 h after dislocation. Redislocation occurred in 3 (5.7%) children and coxa magna developed in 5 (9.4%). Long-term functional outcome of 42 patients resulted in full recovery, and it was fair to good in 3 (including 2 children with AVN). All neglected cases (≥4 weeks from trauma) needed open reduction in the operating room (OR). AVN was identified in 11 children (47.8%). Hip function was completely recovered in 16 (70%) patients. Conclusions THD in this age group mainly occurs with low-energy trauma and leads to posterior dislocations. Urgent closed reduction of acute cases are done in the OR, or the ED. ED reduction appears to be safe. Neglected THDs need open reduction.

The Pediatric Emergency Care Applied Research Network intermediate-risk predictors were not associated with scanning decisions for minor head injuries

This study determined the predictors associated with the decision to perform a computed tomography (CT) scan in children with a minor head injury (MHI). We focused on those facing an intermediate risk of clinically important traumatic brain injury (ciTBI), according to the Pediatric Emergency Care Applied Research Network (PECARN) prediction rule.

Manpower crisis in emergency medicine: can residency programs make an impact?

Une etude sur la main-d’œuvre canadienne menee en 1994 avait predit une penurie a l’echelle nationale de 562 medecins d’urgence qualifies avant 2001. Plusieurs facteurs ont change depuis la publication de ces donnees; cependant, aucun n’a change l’ordre de grandeur de cette penurie. A la lumiere de ces renseignements, on a etudie la situation de la Edmonton Capital Health Region (CHR) et evalue l’impact des programmes de residence en MU de l’Universite de l’Alberta (CRMC [College Royal des medecins et chirurgiens du Canada] et CMFC [College des medecins de famille du Canada], crees en 1992) sur les besoins locaux en main-d’œuvre. Le nombre de medecins d’urgence certifies dans la CHR est passe de 9 du CRMC-MU et 2 du CMFC-MU en 1990 a 14 du CRMC-MU et 16 du CMFC-MU en 1999, soit une augmentation de 27 %. Le gain le plus important provenait du recrutement de 14 diplomes en medecine d’urgence de la region; cependant, malgre ce succes, et meme avec un recrutement de 100 % des diplomes de l’Universite de l’Alberta, on constate encore une penurie importante de medecins d’urgence dans la CHR. Cette situation n’est pas unique. Elle est le resultat d’un nombre insuffisant de postes de formations en medecine d’urgence au Canada. La seule solution possible a long terme serait d’augmenter considerablement le nombre de postes de residence du CRMC tout en maintenant, et dans certaines juridictions en augmentant, le nombre de diplomes du CMFC.

Emergency Department Pain Management in Pediatric Patients With Fracture or Dislocation in a Bi-Ethnic Population

STUDY OBJECTIVE We determine whether ethnicity in a bi-ethnic population of northern Israel is associated with disparities in pediatric emergency department (ED) opioid analgesia in patients with fracture or dislocation. METHODS A retrospective cohort study was conducted. All records of patients aged 3 to 15 years and receiving a diagnosis of a limb fracture or dislocation were extracted. Data on demographics, including ethnicity, nurse ethnicity, pain level, and pain medication, were collected. Medications were administered according to a nurse-driven pain protocol. RESULTS During the nearly 4-year study period, 3,782 children with fractures visited the ED, 1,245 Arabs and 2,537 Jews. Of these, 315 Arabic patients and 543 Jewish patients had a pain score of 7 to 10. The proportion of Arabic and Jewish children who received opioid therapy was 312 of 315 (99.05%) and 538 of 543 (99.08%), respectively (difference 0.03%; 95% confidence interval -0.13% to 0.19%). Of the 315 Arabic children, 99 were approached by Arabic nurses (31.4%), and 98 of those received opioids (98.9%); 216 were approached by Jewish nurses (68.6%), and 214 of those received opioids (99%). Of the 543 Jewish children, 351 were approached by Jewish nurses (64.6%), and 348 of those received opioids (98.9%); 192 were approached by Arab nurses (35.4%), and 190 of those received opioids (98.9%). During the 2014 11-week Israeli-Palestinian armed conflict, 232 children with fractures visited the ED, 87 Arabs and 145 Jews, of whom 16 and 27 had pain scores of 7 to 10. The proportion of Arabic and Jewish children who received opioid medication was 16 of 16 (100%) and 26 of 27 (96%), respectively (difference 4%; 95% confidence interval -16% to 18%). CONCLUSION Findings suggest that ethnic differences, including during periods of conflicts, have no effect on opioid analgesia in this ED.

Resource contribution by Canadian faculties of medicine to the discipline of emergency medicine.

OBJECTIVE Undergraduate and postgraduate emergency medicine (EM) education has developed rapidly over the last 20 years. Our objective was to establish a national educational inventory, cataloguing the human and financial resources provided to EM programs by Canadian faculties of medicine. METHODS A 17-question survey was distributed to all 27 Canadian EM program directors, representing 11 Royal College of Physicians and Surgeons of Canada (RCPSC) programs and 16 College of Family Physicians of Canada (CFPC-EM) programs. The questionnaire addressed teaching responsibilities, teaching support and academic support in each program. RESULTS All 27 program directors returned valid questionnaires. Annually, an estimated 3,049 students and residents participate in EM learning. This includes 1,369 undergraduates (45%), 1,621 postgraduates (53%) and 59 others (2%). Of the postgraduates, 173 are EM residents -- 92 (53%) in RCPSC programs and 81 (47%) in CFPC-EM programs. Overall, 587 EM faculty teach residents and students, but only 36 (6%) of these hold academic geographical full time positions. At the university level, all 16 CFPC-EM programs are administered by departments of family medicine. Of 11 RCPSC programs, 1 has full departmental status, 2 are free-standing divisions, 3 are administered through family medicine, 3 through medicine, 1 through surgery and 1 by other arrangements. Currently 8 programs (30%) have associate faculty, 14 (52%) have designated research directors and 10 (37%) describe other human resources. Sixteen (59%) programs receive direct financial and administrative support and 17 (63%) receive financial support for resident initiatives. Only 8 program directors (30%) perceive that they are receiving adequate support. CONCLUSIONS Despite major teaching and clinical responsibilities within the faculties of medicine, Canadian EM programs are poorly supported. Further investment of human and financial and human resources is required.

Sedation for children with intraoral injuries in the emergency department: a case-control study.

Objective Intraoral procedures (IOPs) are performed within the oral cavity of a spontaneously breathing, deeply sedated child. The objective of this study was to retrospectively evaluate the safety of sedation for IOP in a pediatric emergency department. Methods An unmatched, case-control study was conducted. The records of patients who had an IOP between January 1, 2012, and December 31, 2012, were analyzed. We evaluated the rate of serious adverse events during sedation (SAEDS) in patients who had an IOP (case subjects) and in patients who had a closed reduction of a forearm fracture (controls) and compared the 2 cohorts. Results Forty-one study subjects and 38 controls had complete records. Demographic characteristics were similar for both groups. Cases and controls were treated with the combination of propofol-ketamine for most of the cases (30/41 [73.2%] and 32/38 [84.2%]), and doses were similar between the groups. Study subjects had 5 hypoxic events and 2 apneic events; controls had 4 hypoxic events and 2 apneic events. No aspiration events were recorded. There were no statistically significant differences in the rate of SAEDS between the 2 groups (P = 0.55 and P = 0.54, respectively). All SAEDS were successfully managed in the emergency department, and no patient required hospitalization due to an adverse reaction. Conclusions Findings of this study suggest that when performed by a skilled provider, sedation for an IOP is as safe as sedation for a fracture reduction.
