Optimization of propofol dose shortens procedural sedation time, prevents resedation and removes the requirement for post-procedure physiologic monitoring

Objective: To examine the effect of propofol dosing (total dose and number of doses) on patient sedation time and likelihood of resedation. Methods: This was a prospective, observational patient series in an urban district hospital ED with 42 000 attendances per annum. Patients undergoing an emergent procedure requiring procedural sedation were included. Titrated intravenous propofol was administered according to departmental procedure. Standardized consent and data collection forms were used. Time taken for the patient to become conversational after first administration was recorded and any resedation documented. Results: Four hundred patients, undergoing 404 procedures, were enrolled for the period commencing August 2004 until March 2006. The mean initial propofol bolus was 0.8 mg/kg (SD 0.6), and mean total propofol dose was 1.8 mg/kg (SD 1.0), comprising a mean of 2.3 (SD 2.1) doses of 15.8 mg (SD 11.4). Mean sedation time was 11.8 min (SD 6.9), and increased sedation times were associated with higher total propofol dose and number of boluses (P < 0.0001). Resedation occurred in two patients (0.5%, 95% CI 0–1.6%). Conclusion: Shorter sedation times are seen with lower doses of propofol. Patients do not need prolonged post‐procedure monitoring because the occurrence of spontaneous resedation associated with propofol use is a rare event. This has implications for patient flow and staff resource allocation in a busy ED.     

Comparison of Adverse Events during Procedural Sedation between Specially Trained Pediatric Residents and Pediatric Emergency Physicians in Israel

Objectives:  The aim was to compare the rate of procedural sedation–related adverse events of pediatric residents with specific training in "patient safety during sedation" and pediatric emergency physicians (PEPs) who completed the same course or were teaching faculty for it.
Methods:  This prospective single-blinded, nonrandomized study was conducted in two university-affiliated pediatric emergency departments (PEDs) in Israel. Pediatric residents who were authorized to perform unsupervised sedations had previously completed a course in patient safety during sedation. Unsupervised sedations by residents were defined as sedations where the entire procedure was performed independently. Study subjects had autonomy in choosing medications for sedation. Adverse events were defined as transient hypoxia (oxygen saturation ≤ 90%) or apnea. Adverse outcomes were situations where intubation or hospitalization directly related to sedation complications would occur. Sedations over 12 consecutive months were recorded, and rates of adverse events in each group were compared.
Results:  A total of 984 eligible sedations were recorded, 635 by unsupervised residents and 349 by PEPs. A total of 512 (80.6%) sedations were performed by residents when attending physicians were not in the ED. The total adverse event rate was 24/984 (2.44%). When the two groups used a similar type drugs, residents had 8/635 (1.26%) events, compared to 11/328 (3.35%) by PEPs. There was no statistically significant difference in the rates of hypoxia or apnea between the two groups (p = 0.29 and p = 0.18, respectively). Adverse outcomes did not occur.
Conclusions:  Unsupervised pediatric residents with training in patient safety during sedation performed procedural sedations with a rate of adverse events similar to that of PEPs.     

Why don't trainees pass the emergency medicine fellowship examination?

The pass rate in the Australasian College for Emergency Medicine Fellowship exams between 1996 and 2003 inclusive averaged 61%, substantially lower than that of other specialties with comparable training structures. The explanation for this pass rate, which many would judge as unacceptably low, is likely to be multi-factorial. Possible factors that should be considered include trainee selection, training programme structure, the impact of the Director of Emergency Medicine Training, examination preparation, examination validity and examination reliability. Each of these potential factors needs to be addressed in a systematic fashion in the context of inevitable and increasing internal and external scrutiny of the outcomes of our training programme.     

Incidence and Characteristics of Fall-related Emergency Department Visits

Abstract. Objective: Unintentional falls are the leading cause of injury and the second most common cause of unintentional injury deaths in the United States, and place a great burden on EDs. In this study, the objective was to describe the incidence and characteristics of ED visits associated with unintentional falls in the United States.
Methods: The authors performed a secondary analysis on data from the National Center for Health Statistics' National Hospital Ambulatory Medical Care Survey for 1992–1994. An ED visit was defined as fall-related if an ICD-9-CM cause of injury code was reported as E880.0–886.9 or E888.
Results: There were an estimated 7,946,000 fall-related ED visits per year, corresponding to an annual rate of 3.1 per 100 persons (95% CI = 2.8 to 3.4). Children under 5 years of age comprised the largest proportion of visits (14%). Among those visits coded with respect to place of occurrence, the rate of visits associated with falls occurring at home (1.7/100; 95% CI = 1.6 to 1.9) was significantly higher than that associated with falls occurring in all other locations combined (1.1/100; 95% CI = 1.0 to 1.2). The mean injury severity score increased significantly with the age of the patient. Fall-related ED visits resulted in an estimated 860,000 hospitalizations, 62% of which involved individuals aged 65 years and older. An estimated $2.45 billion per year was paid for fall-related ED visits. Government sources paid all or part of 41% of visits.
Conclusions: This study reports nationally representative data describing the incidence and characteristics of fall-related ED visits. These data expand what is known about the epidemiology of falls and help to define the burden that fall injuries place on EDs in the United States. The results of this study could serve as a benchmark to evaluate the effectiveness of future fall prevention efforts.     

CFTR rescue with VX-809 and VX-770 favors the repair of primary airway epithelial cell cultures from patients with class II mutations in the presence of Pseudomonas aeruginosa exoproducts

Background

Progressive airway damage due to bacterial infections, especially with Pseudomonas aeruginosa remains the first cause of morbidity and mortality in CF patients. Our previous work revealed a repair delay in CF airway epithelia compared to non-CF. This delay was partially prevented after CFTR correction (with VRT-325) in the absence of infection. Our goals were now to evaluate the effect of the Orkambi combination (CFTR VX-809 corrector?+?VX-770 potentiator) on the repair of CF primary airway epithelia, in infectious conditions.

Association between continuity of care in Swedish primary care and emergency services utilisation: a population-based cross-sectional study

Objective: The primary objective of this study was to determine the association between longitudinal continuity of care (CoC) in Swedish primary care (PC) and emergency services (ES) utilisation.

Study design: A cross-sectional analysis of longitudinal population data. Setting. PC centres, out-of-hours PC facilities and emergency departments (EDs) in Blekinge County in southern Sweden. Subjects: People of all ages who lived in Blekinge County and who had made two or more visits per year to a general practitioner (GP) during office hours from 1 January 2012 to 31 December 2014.

Main outcome measure: ES utilisation.

Results: Eight-thousand one-hundred and eighty-five people were included in the study. CoC was quantified using three different indices—Usual Provider of Care index (UPC), Continuity of Care index (CoCI), and Sequential Continuity index (SECON). The CoC that the PC centres could offer their enrolled patients varied significantly between the different centres, ranging from 0.23–0.57 for UPC, 0.12–0.43 for CoCI, and 0.25–0.52 for SECON. Association between the three CoC indices and ES utilisation was computed as an incidence rate ratio which ranged between 0.50 and 0.59.

Conclusion: Longitudinal CoC was shown to have a negative association with ES utilisation. The association was significant and of a magnitude that implies clinical relevance. Computed incidence rate ratios suggest that patients with the lowest CoC had twice as many ES visits compared to patients with the highest CoC.

Temporal Trends in Outcomes after Out-of-Hospital Cardiac Arrests Witnessed by Emergency Medical Services in Japan: A Population-Based Study

Objective: Survival after out-of-hospital cardiac arrests (OHCA) witnessed by emergency medical service (EMS) personnel has been insufficiently understood. The aim of this study was to evaluate temporal trends in survival after EMS-witnessed OHCAs in Japan. Methods: A nationwide, population-based, observational cohort study of consecutive adult OHCA patients with emergency responder resuscitation attempts from January 2005 to December 2012 in Japan. We assessed the trends in annual incidence, characteristics, and outcomes of OHCA patients witnessed by EMS personnel. Multiple logistic regression analysis was used to assess factors that were potentially associated with neurologically favorable outcome defined as cerebral performance category scale 1or 2. Results: During the study period, a total of 66,760 EMS-witnessed OHCAs were documented. The annual incidence rates per 100,000 persons of EMS-witnessed OHCA patients increased from 4.6 (n = 7219) in 2005 to 4.9 (n = 9256) in 2012 (p for trend = 0.035). The proportion of one-month survival with neurologically favorable outcome improved from 5.9% in 2005 to 8.6% in 2012 (p for trend < 0.001), and the proportion increased from 22.1% in 2005 to 30.2% in 2012 in cases with shockable rhythm (p for trend < 0.001). In a multivariate analysis, adults, male gender, shockable rhythm, presumed cardiac origin, and year were associated with a better neurological outcome. Conclusions: In this population, the proportion of one-month survival with neurologically favorable outcome among OHCA patients witnessed by EMS personnel significantly improved during the study period.     

Understanding Surge Capacity: Essential Elements

As economic forces have reduced immediately available resources, the need to surge to meet patient care needs that exceed expectations has become an increasing challenge to the health care community. The potential patient care needs projected by pandemic influenza and bioterrorism catapulted medical surge to a critical capability in the list of national priorities, making it front-page news. Proposals to improve surge capacity are abundant; however, surge capacity is poorly defined and there is little evidence-based comprehensive planning. There are no validated measures of effectiveness to assess the efficacy of interventions. Before implementing programs and processes to manage surge capacity, it is imperative to validate assumptions and define the underlying components of surge. The functional components of health care and what is needed to rapidly increase capacity must be identified by all involved. Appropriate resources must be put into place to support planning factors. Using well-grounded scientific principles, the health care community can develop comprehensive programs to prioritize activities and link the necessary resources. Building seamless surge capacity will minimize loss and optimize outcomes regardless of the degree to which patient care needs exceed capability.
