Background

Return visits to the emergency department (RTED) contribute to overcrowding and may be a quality of care indicator. Previous studies focused on factors predicting returns to and from the same center. Little is known about RTEDs across a range of community and specialty hospitals within a large geographic area.

Objective

We sought to measure the frequency of pediatric RTEDs and describe their directional pattern across centers in a large catchment area.

Methods

We conducted a multicenter, retrospective cross-sectional study of pediatric emergency visits in the Vancouver lower mainland within 1 year. Visits were linked across study sites, including one pediatric quaternary care referral center and 17 sites ranging from large regional centers to smaller community emergency departments (EDs). Returns were defined as subsequent visits to any site with a compatible diagnosis within 7 days of an index visit.

Results

Among a total of 139,278 index ED visits by children, 12,133 (8.7% [95% confidence interval 8.6–8.9%]) were associated with 14,645 return visits to an ED. Three quarters of all index visits occurred at a general ED center, of which 8.9% had at least one RTED and 22% of these returns occurred at the pediatric ED (PED). Among PED index visits, 8.2% had at least one RTED and 13.6% of these returned to a general center. Overall, 38.9% of all RTEDs occurred at the PED. Multivariate regression did not identify any statistically significant association between ED crowding measures and likelihood of RTEDs.

Conclusions

Compared to single-center studies, this study linking hospitals within a large geographic area identified a higher proportion of RTEDs with a disproportionate burden on the PED.  相似文献

Background

Quick Sequential Organ Failure Assessment (qSOFA) is a prognostic score for patients with sepsis.

Objective

Our aim was to compare the area under the receiver operating curve (AUROC), sensitivity, specificity, and likelihood ratios of qSOFA vs. systemic inflammation response syndrome (SIRS) in predicting in-hospital mortality among emergency department (ED) patients with suspected infection admitted to intensive care units (ICUs).

Methods

We conducted a retrospective cohort chart review study of ED patients admitted to an ICU with suspected infection from August 1, 2012 to February 28, 2015. We included all patients with body fluid cultures sampled either during their ED stay without antibiotic administration or within 24 h of antibiotics administered in the ED. Trained chart abstractors blinded to the study hypothesis double-entered data from each patient's electronic medical record including demographic characteristics, vital signs, laboratory study results, physical examination findings, and in-hospital mortality. We then calculated the AUROC, sensitivity, specificity, and likelihood ratios for qSOFA and SIRS for predicting in-hospital mortality.

Results

Of 214 patients admitted to an ICU with presumed sepsis, 39 (18.2%) died during hospitalization. The AUROC value was 0.65 (95% confidence interval [CI] 0.56–0.74) for SIRS vs. 0.66 (95% CI 0.57–0.76) for qSOFA; 2+ qSOFA criteria predicted in-hospital mortality with 89.7% sensitivity, 27.4% specificity, 1.2 positive likelihood ratio, and 0.4 negative likelihood ratio.

Conclusions

Among ED patients admitted to an ICU, the SIRS and qSOFA criteria had comparable prognostic value for predicting in-hospital mortality. These prognostic values are similar to those reported by the Sepsis-3 guidelines for ICU encounters.  相似文献

Background

Colchicine poisoning is an uncommon but serious form of drug intoxication. It may produce life-threatening systemic effects. In toxic doses it produces nausea and vomiting and bone marrow suppression, often leading to sepsis, hypocalcemia, adult respiratory distress syndrome, and direct cardiotoxic effects.

Objective

The aim of this study was to describe demographic features and the outcome of patients poisoned with colchicine.

Methods

A retrospective study of the pediatric intensive care unit database was performed for patients ≤18 years of age who had colchicine poisoning between July 2008 and July 2013.

Results

The total number of patients with drug poisoning in the study period was 144. Nine of 144 were related to colchicine poisoning. The median age was 4 years (range 20 months to 16 years) and the number of females was five. Six of the nine cases presented after ingesting <0.5 mg/kg, whereas two patients had consumed 0.5 to 0.8 mg/kg. One patient had received colchicine >0.8 mg/kg. Three patients died.

Conclusions

Among drug intoxications, colchicines can lead to severe clinical conditions. All patients suspected of having colchicine intoxication should be managed in the pediatric intensive care unit regardless of the actual degree of poisoning.  相似文献

Background

Stroke is a primary cause of death and disability in upper-middle–income countries such as Colombia. Given the lack of comprehensive rehabilitation for stroke patients in Colombia, there is a need to assess longitudinal mental health problems poststroke in this region.

Objective

To compare the course of mental health in stroke patients to healthy controls over the first year poststroke in Ibague, Colombia.

Design

Cross-sectional study.

Setting

The Psychological Attention Center of Antonio Nariño University in Ibague, Colombia.

Participants

Stroke patients (n = 50) and age- and gender-matched healthy controls (n = 50).

Methods

Patients and controls completed self-report Spanish versions of demographic information, injury-related characteristics, and mental health questionnaires

Main Outcome Measurements

Outcomes assessed included mental health (depression, anxiety, and stress) at 3, 6, and 12 months poststroke.

Results

Hierarchical linear models suggested that stroke patients had worse depression and anxiety over time than controls (P < .001). Among patients, depression and anxiety decreased over time (P < .001), whereas stress increased over time (P < .01). The findings suggest that although anxiety and depression improved over time in stroke patients, their mental health remained significantly lower than that of controls.

Conclusions

This is the first study to examine the course of mental health over the first year poststroke in Latin America, specifically in Ibague, Colombia. Despite the improvements in anxiety and depression over the first year poststroke, patient anxiety and depression were still worse in comparison to those in healthy controls. The current findings indicate a need for rehabilitation services in Colombia, especially targeting mental health issues.

Background

Scribe use throughout health care is becoming more common. There is limited peer-reviewed literature supporting this emerging role in health care despite rapid uptake of the role.

Objectives

Our study assesses impact of scribes on relative value units (RVUs) in adult and pediatric emergency departments (EDs).

Methods

A prospective cohort study was developed in a tertiary academic ED. Charts were coded by an external billing and coding company, then returned and mapped by International Classification of Diseases, 9th revision diagnostic codes. After training by a staff member with significant experience in implementing scribe programs, scribes provided 1-to-1 support to a provider as staffing allowed. Comparisons were made between scribed and nonscribed visits.

Results

There were 49,389 patient visits during the study period (39,926 adult [80.84%] and 9463 pediatric [19.16%] visits), of which 7865 (15.9%) were scribed. For adults, scribed visits produced 0.20 additional RVUs per patient (p < 0.001). Scribes generated additional RVUs in Emergency Severity Index (ESI) 2 (p < 0.001) and 3 (p < 0.001) patients. There were variable effects of scribes on RVUs by diagnostic codes. For pediatric patients, scribed encounters generated 0.08 fewer RVUs per patient (p = 0.007). ESI score had no effect on RVUs. The impact of scribes on pediatric diagnostic groupings was inconsistent.

Conclusions

Scribes had a positive impact on RVUs in adult but not pediatric patients. Among adults, scribes led to higher RVUs in ESI 2 and 3 but not 4 and 5 patients, perhaps suggesting a limitation to improve revenue capture on lower-acuity patients.  相似文献

Background

Urinalysis testing is frequently ordered in the emergency department (ED), but contamination of urine specimens limits the interpretation of results. The mid-stream, clean-catch (MSCC) procedure for urine specimen collection is recommended to decrease contamination rates, but without instructions this procedure has poor compliance.

Objective

To evaluate the effectiveness of written instructions alone, we analyzed the rate of specimen contamination, defined by presence of squamous epithelial cells (SECs) and culture results, in the ED after posting information on the MSCC procedure.

Methods

Instructions in simple English for the MSCC procedure were posted in all patient-accessible restrooms in the ED. Frequency of contamination, defined microscopically as > 5 SECs per high-powered field or through growth of mixed or non-pathologic flora on urine culture, was determined over a 3-month period for comparison to historical controls from the previous year.

Results

During the intervention period, 754 urinalyses were sent, with 392 contaminated specimens (51.98%), and 193 urine cultures were sent, with 77 contaminated results (39.8%). Historical controls from the previous year yielded 827 urinalyses sent, with 430 contaminated (51.99%), and 251 urine cultures, with 125 contaminated results (49.8%). The difference between groups was not significant for urinalysis (p = 0.99) or urine culture (p = 0.13).

Conclusions

A poster-based educational intervention with instructions on MSCC procedure failed to decrease contamination rates in this ED-based study. Possible explanations include poor compliance with MSCC technique in the ED, or poor efficacy of this technique at decreasing contamination rates. These results may indicate that other efforts are necessary to improve urine collection methods.  相似文献

Background

Unintentional pediatric cocaine exposures are rare but concerning due to potentially serious complications such as seizures, dysrhythmias, and death.

Objectives

The objectives were to assess the demographic and clinical characteristics of pediatric cocaine exposures reported to the California Poison Control System.

Methods

This is a retrospective study of all confirmed pediatric (< 6 years of age) cocaine exposures reported to the California Poison Control System from January 1, 1997–September 30, 2010. Case narratives were reviewed for patient demographics, exposure details, clinical effects, therapy, hospitalization, and final outcome.

Results

Of the 86 reported pediatric cocaine exposures, 36 had positive urine drug testing and were included in the study cohort. The median age at presentation was 18 months (range: 0–48 months), and 56% were male (n = 20). The most common clinical manifestations were tachycardia and seizures. The most common disposition was admission to an intensive care unit (n = 14; 39%). Eleven cases (31%) were classified as having a major effect as per American Association of Poison Control Centers case coding guidelines. One child presented in asystole with return of spontaneous circulation after cardiopulmonary resuscitation and multiple vasoactive medications. The proportion of cocaine exposures with serious (moderate or major) outcomes (66.7%; 95% confidence interval 50.3–79.8%) was higher than other pediatric poisonings reported to the American Association of Poison Control Centers during the study period (0.88%; 95% confidence interval 0.87–0.88).

Conclusions

Although pediatric cocaine exposures are rare, they result in more severe outcomes than most unintentional pediatric poisonings. Practitioners need to be aware of the risk of recurrent seizures and cardiovascular collapse associated with cocaine poisoning.  相似文献

Objectives

To examine the effect of experimental knee pain on perceived knee pain and gait patterns and to examine the efficacy of transcutaneous electrical nerve stimulation (TENS) on perceived knee pain and pain-induced knee gait mechanics.

Design

Crossover trial.

Setting

Biomechanics laboratory.

Participants

Recreationally active, individuals without musculoskeletal pain aged 18 to 35 years (N=30).

Interventions

Thirty able-bodied individuals were assigned to either a TENS (n=15) or a placebo (n=15) group. All participants completed 3 experimental sessions in a counterbalanced order separated by 2 days: (1) hypertonic saline infusion (5% NaCl); (2) isotonic saline infusion (0.9% NaCl); and (3) control. Each group received sensory electrical stimulation or placebo treatment for 20 minutes, respectively.

Main Outcome Measures

Perceived pain was collected every 2 minutes using a 10-cm visual analog scale (VAS) for 50 minutes and analyzed using a mixed model analysis of covariance with repeated measures. Gait analyses were performed at baseline, infusion, and treatment. Sagittal and frontal knee angles and internal net joint torque across the entire stance were analyzed using a functional data analysis approach.

Results

Hypertonic saline infusion increased perceived pain (4/10cm on a VAS; P<.05) and altered right knee angle (more flexion and less abduction; P<.05) and internal net joint torque (less extension and greater abduction; P<.05) across various stance phases. TENS treatment reduced perceived pain and improved right sagittal gait abnormalities as compared with placebo treatment (P<.05).

Conclusions

This pain model increases perceived pain and induces compensatory gait patterns in a way that indicates potential quadriceps weakness. However, TENS treatment effectively reduces perceived pain and restores pain-induced gait abnormalities in sagittal knee mechanics.  相似文献

Objective

To determine whether multifidi size, intramuscular fat, or both, are associated with self-reported and performance-based physical function in older adults with and without chronic low back pain (LBP).

Design

Case-control study.

Setting

Individuals participated in a standardized evaluation in a clinical laboratory and underwent magnetic resonance imaging (MRI) of the lumbar spine at a nearby facility.

Participants

A volunteer sample of community-dwelling older adults (N=106), aged 60 to 85 years, with (n=57) and without (n=49) chronic LBP were included in this secondary data analysis.

Intervention

Average right-left L5 multifidi relative (ie, total) cross-sectional area (CSA), muscle-fat infiltration index (MFI) (ie, a measure of intramuscular fat), and relative muscle CSA (rmCSA) (ie, total CSA minus intramuscular fat CSA) were determined from MRIs. Linear regression modeling was performed with physical function measures as the dependent variables. Age, sex, and body mass index were entered as covariates. The main effects of L5 multifidi MFI and rmCSA, as well as their interaction with group assignment, were compared as independent variables.

Main Outcome Measures

Medical Outcomes Study 36-Item Short-Form Health Survey physical functioning subscale, timed Up and Go, gait speed, and fast stair descent performance.

Results

Interaction terms between L5 multifidi MFI and group assignment were found to be significant contributors to the variance explained in all physical function measures (P≤.012). Neither the main effect nor the interaction with group assignment for L5 multifidi rmCSA significantly contributed to the variance explained in any of the physical function measures (P>.012).

Conclusions

Among older adults with chronic LBP of at least moderate intensity, L5 multifidi muscle composition, but not size, may help to explain physical function.  相似文献

Objective

To examine how patient satisfaction with care coordination and quality and access to medical care influence functional improvement or deterioration (activity limitation stage transitions), institutionalization, or death among older adults.

Design

National representative sample with 2-year follow-up.

Setting

Medicare Current Beneficiary Survey from calendar years 2001 to 2008.

Participants

Community-dwelling adults (N=23,470) aged ≥65 years followed for 2 years.

Interventions

Not applicable.

Main Outcome Measures

A multinomial logistic regression model taking into account the complex survey design was used to examine the association between patient satisfaction with care coordination and quality and patient satisfaction with access to medical care and activities of daily living (ADL) stage transitions, institutionalization, or death after 2 years, adjusting for baseline socioeconomics and health-related characteristics.

Results

Out of 23,470 Medicare beneficiaries, 14,979 (63.8% weighted) remained stable in ADL stage, 2508 (10.7% weighted) improved, 3210 (13.3% weighted) deteriorated, 582 (2.5% weighted) were institutionalized, and 2281 (9.7% weighted) died. Beneficiaries who were in the top quartile of satisfaction with care coordination and quality were less likely to be institutionalized (adjusted relative risk ratio [RRR], .68; 95% confidence interval [CI], .54–.86). Beneficiaries who were in the top quartile of satisfaction with access to medical care were less likely to functionally deteriorate (adjusted RRR, .87; 95% CI, .79–.97), be institutionalized (adjusted RRR, .72; 95% CI, .56–.92), or die (adjusted RRR, .86; 95% CI, .75–.98).

Conclusions

Knowledge of patient satisfaction with medical care and risk of functional deterioration may be helpful for monitoring and addressing disability-related health care disparities and the effect of ongoing policy changes among Medicare beneficiaries.  相似文献

Background

Insect venom anaphylaxis is a potentially life-threatening disorder. Transient coagulopathy in insect venom anaphylaxis is a rare phenomenon.

Case Report

A 41-year-old man presented to the Emergency Department (ED) with hypotension after a run in a park. History and examination revealed signs of anaphylactic shock. A deranged coagulation profile with a normal platelet count led to the diagnosis of wasp sting anaphylaxis.

Why Should an Emergency Physician Be Aware of This?

Transient deranged coagulation profile with a normal platelet count may arise from insect venom anaphylaxis. This specific finding may aid the emergency physician in making a diagnosis of anaphylactic shock in an otherwise healthy patient presenting with shock with no apparent cause.  相似文献

Background

Patients have expressed concern about undergoing procedures involving trainees, even with direct attending physician supervision. Little literature has examined the effect of trainee involvement on patient outcomes.

Objective

We aimed to evaluate the effect of trainee involvement on patient complications, immediate pain reduction, and fluoroscopic time for different fluoroscopic injection types.

Design

Retrospective review.

Setting

Four academic outpatient institutions with Accreditation Council for Graduate Medical Education (ACGME)?accredited residency (physical medicine and rehabilitation, or anesthesiology) or fellowship (sports medicine or pain medicine) programs from 2000 to 2015.

Patients

All patients receiving fluoroscopically guided hip (HI), sacroiliac joint (SIJI), transforaminal epidural (TFEI), and/or interlaminar epidural injections (ILEI, performed at only 1 institution).

Methods

Outcome measures were examined based on the presence or absence of a trainee during the procedure.

Main Outcome Measurements

The primary outcome was the number of immediate complications, with secondary outcomes being fluoroscopic time per injection (FTPI) and immediate numeric rating scale percentage improvement.

Results

Trainees were involved in 67.0% of all injections (N = 7,833). Complication rates or improvements in numeric rating scale scores showed no significant differences with trainee involvement for any injection type (P > .05). Trainee involvement was associated with increased FTPI for ILEIs (18.2 ± 10.1 seconds with trainees versus 15.1 ± 8.5 seconds without trainees, P < .001), but not for HIs (P = .60) or SIJIs (P = .51). Trainee involvement with TFEIs was dependent on institution for outcome with respect to FTPI (P < .001), with 28.1 ± 17.9 seconds with trainees and 32.1 ± 22.1 seconds without trainees (P = 0.51).

Conclusions

This large multicenter study of academic institutions demonstrates that trainee involvement in fluoroscopically guided injections does not affect immediate patient complications or pain improvement. Trainee involvement does not increase fluoroscopic time for most injections, although there is an institutional difference seen. This study supports the notion that appropriate trainee supervision likely does not compromise patient safety for fluoroscopically guided injections.

Background

Theoretically, patients with only one functional arm secondary to contralateral amputation or paralysis will subject their only functional upper extremity to increased loads. This could become an issue after reverse shoulder arthroplasty (RSA). However, there are no reported data on the implant survival or function for patients with a nonfunctional contralateral upper extremity.

Objective

To report the outcomes of RSA in patients with contralateral upper extremity amputation or paralysis.

Design

Retrospective case series.

Setting

Tertiary university hospital.

Patients

All patients who underwent RSA between January 2004 and December 2013.

Methods

Of 1335 RSA procedures performed, 5 patients had a minimum 2-year follow-up and nonfunctional contralateral upper extremity. There were 3 men and 2 women, with a mean (standard deviation) age and length of follow-up of 72.4 (7.5) years and 56.4 (24-132) months. Two of the patients had a contralateral upper extremity amputation, and the other 3 had contralateral upper extremity paralysis as a result of stroke, traumatic brain injury, and traumatic brachial plexus injury at birth.

Main Outcomes

Pain, range of motion, functional scores (Simple Shoulder Test, American Shoulder and Elbow Society and Quick-Disability of the Arm, Shoulder and Hand), satisfaction, complications/reoperations, and radiographic loosening.

Results

RSA resulted in substantial improvement in pain (P = .008), forward flexion (P = .02), and external range of motion (P = .01). The mean (standard deviation) Simple Shoulder Test, American Shoulder and Elbow Society, and Quick-Disability of the Arm, Shoulder, and Hand scores were 9.8 (1.3), 82 (13), and 17.8 (13.4), respectively. The results were excellent in 3, satisfactory in 1, and unsatisfactory in 1 patient (due only to external rotation limited to 10°). Subjectively, all 5 patients felt greatly improved and stated they would undergo RSA again. There were no complications or reoperations. There were no shoulders with component loosening.

Conclusions

RSA seems to be a safe, effective, and successful surgical procedure for patients with a nonfunctional contralateral upper extremity. Studies with larger sample sizes and longer follow-up will hopefully validate the present findings.

Background

Respiratory events requiring the use of assisted ventilation are relatively common in the emergency department (ED), and can be associated with substantial morbidity and mortality.

Objective

The aim of this study was to describe and elucidate patient and event characteristics associated with mortality and progression to cardiac arrest in ED patients with acute respiratory compromise.

Methods

Data were obtained from the multicenter Get With the Guidelines–Resuscitation® registry. We included patients with acute respiratory compromise defined as absent, agonal, or inadequate respiration that required emergency assisted ventilation. All adult patients between January 2005 and December 2014 with an index event in the ED were included. We used multivariable logistic regression models to assess the association between patient and event characteristics and in-hospital mortality, with cardiac arrest during the event as a secondary outcome.

Results

A total of 3571 events were included. The in-hospital mortality was 34%. Twelve percent of events progressed to cardiac arrest, with a subsequent 82% in-hospital mortality. When adjusting for patient and event characteristics, we found no temporal changes in in-hospital mortality from 2005 to 2014. Several characteristics were associated with increased mortality, such as pre-event hypotension, septicemia, and acute stroke. Similarly, multiple characteristics, including pre-event hypotension, were associated with progression to cardiac arrest.

Conclusions

Patient with acute respiratory compromise in the ED had an in-hospital mortality of 34% in the current study. These patients also have a high risk of progressing to cardiac arrest, with a subsequent increase in in-hospital mortality to 82%. Potentially reversible characteristics, such as hypotension before the event, showed a strong association to in-hospital mortality, along with multiple other patient and event characteristics.  相似文献

Background

Acute promyelocytic leukemia (APL) is a rare but particularly malignant form of acute leukemia that is characterized by a rapid progression to fatal hemorrhage. Survival rates of patients with APL have increased with the introduction of all-trans retinoic acid (ATRA), but early deaths caused by hemorrhage still persist.

Case Report

A man with undiagnosed APL presenting with focal neurologic findings and deteriorating altered mental status caused by an intracranial hemorrhage is discussed.

Why Should An Emergency Physician Be Aware of This?

It is important to consider APL when diagnosing etiologies for intracranial hemorrhage. In addition to standard care, early administration of ATRA is recommended upon clinical suspicion of the disease.  相似文献
