The effect of emergency department crowding on clinically oriented outcomes

Two Hour Evaluation and Referral Model for Shorter Turnaround Times in the emergency department

OBJECTIVE

The objective of this study was to assess the implementation of a novel ED model of care, which combines clinical streaming, team-based assessment and early senior consultation to reduce length of stay.

METHODS

A pre-post-intervention study was used to compare ED performance following an extensive clinical redesign programme. Clinical teams and work sequences were reconfigured to promote the role of the staff specialist, with a focus on earlier decisions regarding disposition. Primary outcome measures were ED length of stay and National Emergency Access Target (NEAT) compliance. Secondary outcomes included referral and workup times, wait times by triage category, ambulance offload times, ward discharges and unit transfers within 24 h of admission, representation within 48 h, and Medical Emergency Response Team (MERT) calls within 24 h of admission.

RESULTS

Two seasonally matched 26 week intervals were compared with adjustment for demographics, triage category and arrival by ambulance. Overall, there was an 18.4% rise in NEAT performance (95% confidence interval (CI): 17.7-19.1) while ED length of stay decreased by a total of 86.8 min (95% CI: 83.6-90.1). Time series analysis did not suggest any preexisting trends to explain these results. The average time to referral decreased by 74.7 min (95% CI: 69.8-79.6) and waiting times decreased across all triage categories. Rates of MERT activation and unplanned representation were unchanged.

CONCLUSION

A facilitated team leader role for senior doctors can help to reduce length of stay by via early disposition, without significant risks to the patient.

A systematic review of the impact of nurse-initiated medications in the emergency department

BACKGROUND

Nurse-initiated medications are one of the most important strategies used to facilitate timely care for people who present to Emergency Departments (EDs). The purpose of this paper was to systematically review the evidence of nurse-initiated medications to guide future practice and research.

METHODS

A systematic review of the literature was conducted to locate published studies and Grey literature. All studies were assessed independently by two independent reviewers for relevance using titles and abstracts, eligibility dictated by the inclusion criteria, and methodological quality.

RESULTS

Five experimental studies were included in this review: one randomised controlled trial and four quasi-experimental studies conducted in paediatric and adult EDs. The nurse-initiated medications were salbutamol for respiratory conditions and analgesia for painful conditions, which enabled patients to receive the medications quicker by half-an-hour compared to those who did not have nurse-initiated medications. The intervention had no effect on adverse events, doctor wait time and length of stay. Nurse-initiated analgesia was associated with increased likelihood of receiving analgesia, achieving clinically-relevant pain reduction, and better patient satisfaction.

CONCLUSION

Nurse-initiated medications are safe and beneficial for ED patients. However, randomised controlled studies are required to strengthen the validity of results.

Simulation for Operational Readiness in a New Freestanding Emergency Department: Strategy and Tactics

Simulation in multiple contexts over the course of a 10-week period served as a core learning strategy to orient experienced clinicians before opening a large new urban freestanding emergency department. To ensure technical and procedural skills of all team members, who would provide care without on-site recourse to specialty backup, we designed a comprehensive interprofessional curriculum to verify and regularize a wide range of competencies and best practices for all clinicians. Formulated under the rubric of systems integration, simulation activities aimed to instill a shared culture of patient safety among the entire cohort of 43 experienced emergency physicians, physician assistants, nurses, and patient technicians, most newly hired to the health system, who had never before worked together. Methods throughout the preoperational term included predominantly hands-on skills review, high-fidelity simulation, and simulation with standardized patients. We also used simulation during instruction in disaster preparedness, sexual assault forensics, and community outreach. Our program culminated with 2 days of in-situ simulation deployed in simultaneous and overlapping timeframes to challenge system response capabilities, resilience, and flexibility; this work revealed latent safety threats, lapses in communication, issues of intake procedure and patient flow, and the persistence of inapt or inapplicable mental models in responding to clinical emergencies.

Applying Systems Engineering Reduces Radiology Transport Cycle Times in the Emergency Department

INTRODUCTION

Emergency department (ED) crowding is widespread, and can result in care delays, medical errors, increased costs, and decreased patient satisfaction. Simultaneously, while capacity constraints on EDs are worsening, contributing factors such as patient volume and inpatient bed capacity are often outside the influence of ED administrators. Therefore, systems engineering approaches that improve throughput and reduce waste may hold the most readily available gains. Decreasing radiology turnaround times improves ED patient throughput and decreases patient waiting time. We sought to investigate the impact of systems engineering science targeting ED radiology transport delays and determine the most effective techniques.

METHODS

This prospective, before-and-after analysis of radiology process flow improvements in an academic hospital ED was exempt from institutional review board review as a quality improvement initiative. We hypothesized that reorganization of radiology transport would improve radiology cycle time and reduce waste. The intervention included systems engineering science-based reorganization of ED radiology transport processes, largely using Lean methodologies, and adding no resources. The primary outcome was average transport time between study order and complete time. All patients presenting between 8/2013-3/2016 and requiring plain film imaging were included. We analyzed electronic medical record data using Microsoft Excel and SAS version 9.4, and we used a two-sample t-test to compare data from the pre- and post-intervention periods.

RESULTS

Following the intervention, average transport time decreased significantly and sustainably. Average radiology transport time was 28.7 ± 4.2 minutes during the three months pre-intervention. It was reduced by 15% in the first three months (4.4 minutes [95% confidence interval [CI] 1.5-7.3]; to 24.3 ± 3.3 min, P=0.021), 19% in the following six months (5.4 minutes, 95% CI [2.7-8.2]; to 23.3 ± 3.5 min, P=0.003), and 26% one year following the intervention (7.4 minutes, 95% CI [4.8-9.9]; to 21.3 ± 3.1 min, P=0.0001). This result was achieved without any additional resources, and demonstrated a continual trend towards improvement. This innovation demonstrates the value of systems engineering science to increase efficiency in ED radiology processes.

CONCLUSION

In this study, reorganization of the ED radiology transport process using systems engineering science significantly increased process efficiency without additional resource use.

Prospective validation of a clinical decision rule to identify patients presenting to the emergency department with chest pain who can safely be removed from cardiac monitoring

BACKGROUND

Most patients with chest pain in the emergency department are assigned to cardiac monitoring for several hours, blocking access for patients in greater need. We sought to validate a previously derived decision rule for safe removal of patients from cardiac monitoring after initial evaluation in the emergency department.

METHODS

We prospectively enrolled adults (age ≥ 18 yr) who presented with chest pain and were assigned to cardiac monitoring at 2 academic emergency departments over 18 months. We collected standardized baseline characteristics, findings from clinical evaluations and predictors for the Ottawa Chest Pain Cardiac Monitoring Rule: whether the patient is currently free of chest pain, and whether the electrocardiogram is normal or shows only nonspecific changes. The outcome was an arrhythmia requiring intervention in the emergency department or within 8 hours of presentation to the emergency department. We calculated diagnostic characteristics for the clinical prediction rule.

RESULTS

We included 796 patients (mean age 63.8 yr, 55.8% male, 8.9% admitted to hospital). Fifteen patients (1.9%) had an arrhythmia, and the rule performed with the following characteristics: sensitivity 100% (95% confidence interval [CI] 78.2%-100%) and specificity 36.4% (95% CI 33.0%-39.6%). Application of the Ottawa Chest Pain Cardiac Monitoring Rule would have allowed 284 out of 796 patients (35.7%) to be safely removed from cardiac monitoring.

INTERPRETATION

We successfully validated the decision rule for safe removal of a large subset of patients with chest pain from cardiac monitoring after initial evaluation in the emergency department. Implementation of this simple yet highly sensitive rule will allow for improved use of health care resources.

Applicability of the modified Emergency Department Work Index (mEDWIN) at a Dutch emergency department

Background

Emergency department (ED) crowding leads to prolonged emergency department length of stay (ED-LOS) and adverse patient outcomes. No uniform definition of ED crowding exists. Several scores have been developed to quantify ED crowding; the best known is the Emergency Department Work Index (EDWIN). Research on the EDWIN is often applied to limited settings and conducted over a short period of time.

Objectives

To explore whether the EDWIN as a measure can track occupancy at a Dutch ED over the course of one year and to identify fluctuations in ED occupancy per hour, day, and month. Secondary objective is to investigate the discriminatory value of the EDWIN in detecting crowding, as compared with the occupancy rate and prolonged ED-LOS.

Methods

A retrospective cohort study of all ED visits during the period from September 2010 to August 2011 was performed in one hospital in the Netherlands. The EDWIN incorporates the number of patients per triage level, physicians, treatment beds and admitted patients to quantify ED crowding. The EDWIN was adjusted to emergency care in the Netherlands: modified EDWIN (mEDWIN). ED crowding was defined as the 75^th percentile of mEDWIN per hour, which was ≥0.28.

Results

In total, 28,220 ED visits were included in the analysis. The median mEDWIN per hour was 0.15 (Interquartile range (IQR) 0.05–0.28); median mEDWIN per patient was 0.25 (IQR 0.15–0.39). The EDWIN was higher on Wednesday (0.16) than on other days (0.14–0.16, p<0.001), and a peak in both mEDWIN (0.30–0.33) and ED crowding (52.9–63.4%) was found between 13:00–18:00 h. A comparison of the mEDWIN with the occupancy rate revealed an area under the curve (AUC) of 0.86 (95%CI 0.85–0.87). The AUC of mEDWIN compared with a prolonged ED-LOS (≥4 hours) was 0.50 (95%CI 0.40–0.60).

Conclusion

The mEDWIN was applicable at a Dutch ED. The mEDWIN was able to identify fluctuations in ED occupancy. In addition, the mEDWIN had high discriminatory power for identification of a busy ED, when compared with the occupancy rate.

The n-by-T Target Discharge Strategy for Inpatient Units

BACKGROUND

Ineffective inpatient discharge planning often causes discharge delays and upstream boarding. While an optimal discharge strategy that works across all units at a hospital is likely difficult to identify and implement, a strategy that provides a reasonable target to the discharge team appears feasible.

METHODS

We used observational and retrospective data from an inpatient trauma unit at a Level 2 trauma center in the Midwest US. Our proposed novel n-by-T strategy-discharge n patients by the Tth hour-was evaluated using a validated simulation model. Outcome measures included 2 measures: time-based (mean discharge completion and upstream boarding times) and capacity-based (increase in annual inpatient and upstream bed hours). Data from the pilot implementation of a 2-by-12 strategy at the unit was obtained and analyzed.

RESULTS

The model suggested that the 1-by-T and 2-by-T strategies could advance the mean completion times by over 1.38 and 2.72 h, respectively (for 10 AM ≤ T ≤ noon, occupancy rate = 85%); the corresponding mean boarding time reductions were nearly 11% and 15%. These strategies could increase the availability of annual inpatient and upstream bed hours by at least 2,469 and 500, respectively. At 100% occupancy rate, the hospital-favored 2-by-12 strategy reduced the mean boarding time by 26.1%. A pilot implementation of the 2-by-12 strategy at the unit corroborated with the model findings: a 1.98-h advancement in completion times (P<0.0001) and a 14.5% reduction in boarding times (P = 0.027).

CONCLUSION

Target discharge strategies, such as the n-by-T, can help substantially reduce discharge lateness and upstream boarding, especially during high unit occupancy. To sustain implementation, necessary commitment from the unit staff and physicians is vital, and may require some training.

Safety and efficiency of emergency department interrogation of cardiac devices

OBJECTIVE

Patients with implanted cardiac devices may wait extended periods for interrogation in emergency departments (EDs). Our purpose was to determine if device interrogation could be done safely and faster by ED staff.

METHODS

Prospective randomized, standard therapy controlled, trial of ED staff device interrogation vs. standard process (SP), with 30-day follow-up. Eligibility criteria: ED presentation with a self-report of a potential device related complaint, with signed informed consent. SP interrogation was by company representative or hospital employee.

RESULTS

Of 60 patients, 42 (70%) were male, all were white, with a median (interquartile range) age of 71 (64 to 82) years. No patient was lost to follow up. Of all patients, 32 (53%) were enrolled during business hours. The overall median (interquartile range) ED vs. SP time to interrogation was 98.5 (40 to 260) vs. 166.5 (64 to 412) minutes (P=0.013). While ED and SP interrogation times were similar during business hours, 102 (59 to 138) vs. 105 (64 to 172) minutes (P=0.62), ED interrogation times were shorter vs. SP during non-business hours; 97 (60 to 126) vs. 225 (144 to 412) minutes, P=0.002, respectively. There was no difference in ED length of stay between the ED and SP interrogation, 249 (153 to 390) vs. 246 (143 to 333) minutes (P=0.71), regardless of time of presentation. No patient in any cohort suffered an unplanned medical contact or post-discharge adverse device related event.

CONCLUSION

ED staff cardiac device interrogations are faster, and with similar 30-day outcomes, as compared to SP.

Factors Affecting Visits to the Emergency Department for Urgent and Nonurgent Ocular Conditions

PURPOSE

To determine the frequency of emergency department (ED) visits for nonurgent and urgent ocular conditions and risk factors associated with ED use for nonurgent and urgent ocular problems.

DESIGN

Retrospective, longitudinal cohort analysis.

PARTICIPANTS

All enrollees aged 21 years or older in a United States managed care network during 2001-2014.

METHODS

We identified all enrollees visiting an ED for ocular conditions identified by International Classification of Diseases, billing codes. Diagnosis is well-described as urgent, nonurgent, or other. We assessed the frequency of ED visits for urgent and nonurgent ocular conditions and how they changed over time. Next, we performed multivariable Cox regression modeling to determine factors associated with visiting an ED for urgent or nonurgent ocular conditions.

MAIN OUTCOME MEASURES

Hazard ratios (HRs) with 95% confidence intervals (CIs) of visiting an ED for urgent or nonurgent ocular conditions.

RESULTS

Of the 11 160 833 enrollees eligible for this study, 376 680 (3.4%) had 1 or more ED visit for an eye-related problem over a mean ± standard deviation of 5.4±3.3 years' follow-up. Among these enrolled, 86 473 (23.0%) had 1 or more ED visits with a nonurgent ocular condition and 25 289 (6.7%) had at least 1 ED visit with an urgent ocular condition. Use of the ED for nonurgent ocular problems was associated with younger age (P < 0.0001 for all comparisons), black race or Latino ethnicity (P < 0.0001 for both), male sex (P < 0.0001), lower income (P < 0.0001 for all comparisons), and those who frequently sought treatment at an ED for nonophthalmologic medical problems in a given year (P < 0.0001). Enrollees with established eye care professionals had a 10% reduced hazard of visiting the ED for nonurgent ocular conditions (adjusted HR, 0.90; 95% CI, 0.88-0.92; P < 0.0001).

CONCLUSIONS

Nearly one-quarter of enrollees who visited the ED for an ocular problem received a diagnosis of a nonurgent condition. Better educating and incentivizing patients to seek care for nonurgent ocular diseases in an office-based setting could yield considerable cost savings without adversely affecting health outcomes and could allow EDs to better serve patients with more severe conditions.

The Most Crowded US Hospital Emergency Departments Did Not Adopt Effective Interventions To Improve Flow, 2007-10

Emergency department (ED) crowding adversely affects patient care and outcomes. Despite national recommendations to address crowding, it persists in most US EDs today. Using nationally representative data, we evaluated the use of interventions to address crowding in US hospitals in the period 2007-10. We examined the relationship between crowding within an ED itself, measured as longer ED lengths-of-stay, and the number of interventions adopted. In our study period the average number of interventions adopted increased from 5.2 to 6.6, and seven of the seventeen studied interventions saw a significant increase in adoption. In general, more crowded EDs adopted greater numbers of interventions than less crowded EDs. However, in the most crowded quartile of EDs, a large proportion had not adopted effective interventions: 19 percent did not use bedside registration, and 94 percent did not use surgical schedule smoothing. Thus, while adoption of strategies to reduce ED crowding is increasing, many of the nation's most crowded EDs have not adopted proven interventions.

Biomarkers in patients admitted to the emergency department after exposure to acrylonitrile in a major railway incident involving bulk chemical material

BACKGROUND

A railway incident with victims of exposure to the cyanogenic substance acrylonitrile (ACN).

AIMS

We retrospectively (i)built an inventory of the clinical characteristics of individuals admitted to surrounding emergency departments (ED's) and (ii)studied the correlation between N-2-cyanoethylvaline (CEV), a biomarker used in a population study for evaluating exposure to ACN, with lactate and thiocyanate (SCN), biomarkers determined during emergency care.

RESULTS

438 patients from 11 ED's were included and presented with known symptoms of ACN poisoning but also with concern about the risks. A comparison of CEV with lactate or SCN was possible in 108 and 73 patients respectively. CEV was very high in a critically ill patient with a high lactate. There was no correlation with CEV in the patients with normal or slightly elevated lactate concentrations. A correlation of CEV with SCN was only observed in smokers.

LIMITATIONS

First there is a lack of data in some clinical files concerning the time and duration of exposure and the smoking-status. A second limitation is that blood samples for biomarkers were not taken systematically in all patients, which may have induced bias. A third limitation is that blood sampling was possibly done outside the correct time window related to the delayed toxicity of ACN. Finally the number of severely-intoxicated patients was low and ACN exposure may not have taken place e.g. in individuals consulting with psychological symptoms. These aspects may have contributed to the below detection limits' analyses of biomarkers.

CONCLUSIONS

CEV was markedly elevated in a severely-intoxicated patient with high lactate, a sensitive marker for CN intoxication. We found no correlation of CEV with normal or slightly elevated lactate concentrations but clinicians should consider the possibility of subsequent rises due to the delay in ACN toxicity. CEV correlated with SCN in smokers, which may be explained by ACN in tobacco smoke and deserves further exploration. Further studies are necessary to evaluate the correlation between biomarkers in acute chemical exposures to ACN and these should be carried out prospectively using a preplanned template.

Emergency department waiting room nurse role: A key informant perspective

BACKGROUND

Emergency departments have become overcrowded with increased waiting times. Strategies to decrease waiting times include time-based key performance indicators and introduction of a waiting room nurse role. The aim of the waiting room nurse role is to expedite care by assessing and managing patients in the waiting room. There is limited literature examining this role.

METHODS

This paper presents results of semi-structured interviews with five key informants to explore why and how the waiting room nurse role was implemented in Australian emergency departments. Data were thematically analysed.

RESULTS

Five key informants from five emergency departments across two Australian jurisdictions (Victoria and New South Wales) reported that the role was introduced to reduce waiting times and improve quality and safety of care in the ED waiting room. Critical to introducing the role was defining and supporting the scope of practice, experience and preparation of the nurses. Role implementation required champions to overcome identified challenges, including funding. There has been limited evaluation of the role.

CONCLUSIONS

The waiting room nurse role was introduced to decrease waiting times and contributed to risk mitigation. Common to all roles was standing orders, while preparation and experience varied. Further research into the role is required.

A Multicenter Evaluation of Emergency Department Pain Care Across Different Types of Fractures

Objectives

To identify differences in emergency department (ED) pain-care based on the type of fracture sustained and to examine whether fracture type may influence the more aggressive analgesic use previously demonstrated in older patients.

Design

Secondary analysis of retrospective cohort study.

Setting

Five EDs (four academic, one community) in the United States.

Participants

Patients (1,664) who presented in January, March, July, and October 2009 with a final diagnosis of fracture (774 long bone [LBF], 890 shorter bone [SBF]).

Measurements

Primary-predictor was type of fracture (LBF vs. SBF). Pain-care process outcomes included likelihood of analgesic administration, opioid-dose, and time to first analgesic. General estimating equations were used to control for age, gender, race, baseline pain score, triage acuity, comorbidities and ED crowding. Subgroup analyses were conducted to analyze age-based differences in pain care by fracture type.

Results

A larger proportion of patients with LBF (30%) were older (>65 years old) compared to SBF (13%). Compared with SBF, patients with LBF were associated with greater likelihood of analgesic-administration (OR = 2.03; 95 CI = 1.58 to 2.62; P  < 0.001) and higher opioid-doses (parameter estimate = 0.268; 95 CI = 0.239 to 0.297; P  < 0.001). When LBF were examined separately, older-patients had a trend to longer analgesic wait-times (99 [55-163] vs. 76 [35-149] minutes, P  = 0.057), but no other differences in process outcomes were found.

Conclusion

Long bone fractures were associated with more aggressive pain care than SBF. When fracture types were examined separately, older patients did not appear to receive more aggressive pain care. This difference should be accounted for in further research.

Emergency Department MRI Scanning of Patients with Multiple Sclerosis: Worthwhile or Wasteful?

BACKGROUND AND PURPOSE

The increasing use of the emergency department MR imaging scanner at our institution raises questions about its added value to certain patient groups. We hypothesized that the use of emergency department MR imaging for identifying active demyelination in MS patients presenting with new neurologic symptoms would be of low yield.

MATERIALS AND METHODS

Electronic medical records were reviewed for patients with MS who had emergency department MR imaging scans for a suspected MS exacerbation between March 1, 2014, and March 1, 2016. Details surrounding patient disposition, imaging, diagnosis, and management were determined.

RESULTS

Of 115 patients in our study, 48 (41.7%) were ultimately diagnosed with an MS exacerbation. Nearly all patients with MS exacerbations (87.5%, 42/48) had active demyelination on their emergency department MR imaging, identified on 30.6% (33/108) of brain MRIs and 20.4% (19/93) of spinal MRIs. The presence of active demyelination at MRI was significantly associated with the ultimate diagnosis of an MS exacerbation (P < .001). MR imaging activity isolated to the spinal cord (ie, not found on concurrent brain MR imaging) was present in only 9 of 93 (9.7%) cases. Pseudoexacerbations accounted for 18 of the alternative diagnoses.

CONCLUSIONS

Emergency department MR imaging is a worthwhile endeavor from a diagnostic standpoint for MS exacerbations despite not being part of the diagnostic criteria. This finding has corresponding downstream impact on management decisions to admit and/or administer intravenous steroids. However, we raise the question of whether clinicians over-rely on emergency department imaging for making exacerbation diagnoses. Additionally, spinal MR imaging is of questionable value as an addition to brain MR imaging due to a low yield of isolated spinal disease.

Systematic identification and management of barriers to vascular surgery patient discharge time of day

OBJECTIVE

Length of stay fails to completely capture the clinical and economic effects of patient progression through the phases of inpatient care, such as admission, room placement, procedures, and discharge. Delayed hospital throughput has been linked to increased time spent in the emergency department and postanesthesia care unit, delayed time to treatment, increased in-hospital mortality, decreased patient satisfaction, and lost hospital revenue. We identified barriers to vascular surgery inpatient care progression and instituted defined measures to positively impact standardized metrics.

METHODS

The study was divided into three periods: preintervention, "wash-in," and postintervention. During the preintervention phase, barriers to patient flow were quantified by an interdisciplinary team. Suboptimal provider communication emerged as the key barrier. An enhanced communication intervention consisting of face-to-face and mobile application-based education on key patient flow metrics, explicit discussion of individual patient barriers to progression at rounds and interdisciplinary huddles, and communication of projected discharge and potential barriers via e-mail was developed with input from all stakeholders. Following a 4-week wash-in implementation phase, data collection was repeated.

RESULTS

The pre- and postintervention patient cohorts accounted for 244.3 and 238.1 inpatient days, respectively. Both groups had similar baseline demographic, clinical characteristics, and procedures performed during hospitalization. The postintervention group was discharged 78 minutes earlier (14:00:32 vs 15:18:37; P = .03) with a trend toward increased discharge by noon (94% vs 88%; P = .09). Readmission rates did not differ (P = .44).

CONCLUSIONS

Implementation of a focused, interdisciplinary, frontline provider-driven, enhanced communication program can be feasibly incorporated into existing specialty surgical workflow. The program resulted in improved timeliness of discharge and projected cost savings, without increasing readmission rates.

Effect of the 4-h target on time-to-analgesia in an Australian emergency department: a pilot retrospective observational study

Objectives The aim of the present study was to assess the relationship between and the effect of the 4-h target or National Emergency Access Target (NEAT) on the time-to-analgesia (TTA), as well as the provision of analgesia in an adult emergency department (ED). Methods The present study was a pilot descriptive explorative retrospective cohort study conducted in a public metropolitan ED. Eligible presentations for analysis were adults presenting with a documented pain score of ≥4 out of 10 between 1 and 14 September 2014. Triage Category 1, pregnant, chest pain and major trauma cases were excluded from the study. As a result, data for 260 patients were analysed. Results Of 260 patients, 176 had analgesia with a median TTA of 49 min. Increased NEAT compliance did not significantly decrease TTA. However, when the factors that affected the provision of analgesia were analysed, an association was demonstrated between Admitted and Short Stay NEAT performance and the provision of analgesia. The likelihood of receiving analgesia at all increased as Admitted and Short Stay NEAT compliance improved. Conclusion NEAT is a significant health policy initiative with little clinical evidence supporting its implementation. However, as the Admitted NEAT compliance increases, the probability of receiving analgesia increases, demonstrating a possible link between hospital function and clinical care provision that needs to be explored further. What is known about the topic? The 4-h target or NEAT is a widely used initiative in EDs to allay crowding and access block. However, little is known of its impact on clinical endpoints, such as TTA. What does this paper add? TTA was not significantly reduced as NEAT compliance increased. However, when the focus was on the probability of receiving analgesia, the results demonstrated that an improvement in Admitted and Short Stay NEAT compliance was associated with an increase in the likelihood of patients receiving analgesia. What are the implications for practitioners? NEAT is a relatively recent initiative, hence evidence of its effect on clinically orientated outcomes is limited. Nevertheless, evidence of safety and effectiveness is emerging. The results of the present pilot study provide preliminary data on the timeliness of patient-centred care as demonstrated by TTA and administration of analgesia when required. Further, the results would seem to suggest that the provision of analgesia is affected by how timely patients are moved out of the ED to the in-patient setting. As for future investigations on TTA as a result of NEAT, a wider time period should be considered so that the accurate effect of compliance thresholds (e.g. ≥90%, 81–89%, ≤80%) of NEAT can be explored.

Accuracy of rapid disposition by emergency clinicians

Objectives Rapid disposition protocols are increasingly being considered for implementation in emergency departments (EDs). Among patients presenting to an adult tertiary referral hospital, this study aimed to compare prediction accuracy of a rapid disposition decision at the conclusion of history and examination, compared with disposition following standard assessment. Methods Prospective observational data were collected for 1 month between October and November 2012. Emergency clinicians (including physicians, registrars, hospital medical officers, interns and nurse practitioners) filled out a questionnaire within 5 min of obtaining a history and clinical examination for eligible patients. Predicted patient disposition (representing ‘rapid disposition’) was compared with final disposition (determined by ‘standard assessment’). Results There were 301 patient episodes included in the study. Predicted disposition was correct in 249 (82.7%, 95% confidence interval (CI) 78.0–86.8) cases. Accuracy of predicting discharge to home appeared highest among emergency physicians at 95.8% (95% CI 78.9–99.9). Overall accuracy at predicting admission was 79.7% (95% CI 67.2–89.0). The remaining 20.3% (95% CI 11.0–32.8) were not admitted following standard assessment. Conclusion Rapid disposition by ED clinicians can predict patient destination accurately but was associated with a potential increase in admission rates. Any model of care using rapid disposition decision making should involve establishment of inpatient systems for further assessment, and a culture of timely inpatient team transfer of patients to the most appropriate treating team for ongoing patient management. What is known about the topic? In response to the National Emergency Access Targets, there has been widespread adoption of rapid-disposition-themed care models across Australia. Although there is emerging data that clinicians can predict disposition accurately, this data is currently limited. What does this paper add? Results of this study support the previously limited evidence that ED practitioners can accurately predict disposition early in the patient journey through ED, and that accuracy is similar across clinician groups. In addition to overall prediction accuracy, admission, discharge and treating team predictions were separately measured. These additional outcomes lend insight into safety and performance aspects relating to a rapid disposition model of care. What are the implications for practitioners? This study offers practical insights that could aid safe and efficient implementation of a rapid disposition model of care.

Waiting and hoping: a phenomenographic study of the experiences of boarded patients in the emergency department

AIMS AND OBJECTIVES

To understand the experiences and concerns of patients in the emergency department during inpatient boarding.

BACKGROUND

Boarding in the emergency department is an increasingly common phenomenon worldwide. Emergency department staff, patients and their families become more stressed as the duration of boarding in the emergency department increases. Yet, there is limited knowledge of the experiences and concerns of boarded patients.

DESIGN

The qualitative approach of phenomenography was used in the study.

METHODS

The phenomenographic study was conducted in one emergency department that treats approximately 15,000 patients each month. Twenty emergency department boarding patients were recruited between July-September 2014. Semi-structured interviews were used for data collection. The seven steps of qualitative data analysis for a phenomenographic study - familiarisation, articulation, condensation, grouping, comparison, labelling and contrasting - were employed to develop an understanding of participants' experiences and concerns during their inpatient boarding in the emergency department.

RESULTS

The perceptions that emerged from the data were collected into four categories of description of the phenomenon of emergency department boarding patients: a helpless choice; loyalty to specific hospitals and doctors; an inevitable challenge of life; and distrust of the healthcare system. The outcome space for the emergency department boarding patients was waiting and hoping for a cure.

CONCLUSION

The experiences and concerns of emergency department boarding patients include physical, psychological, spiritual and health system dimensions. It is necessary to develop an integrated model of care for these patients.

RELEVANCE TO CLINICAL PRACTICE

Understanding the experiences and concerns of patients who are placed on boarding status in the ED will help emergency healthcare professionals to improve the quality of emergency care. There is a need to develop a care model and associated intervention measures for emergency department patients during the boarding process. The results of this study will help health regulatory authorities to develop an appropriate emergency department boarding system so that patients receive better emergency care.

The SCHHS hip fracture clinical network experience-Improving care and outcomes through an interprofessional approach

BACKGROUND

Hip fractures are a major global health care issue, with the 1.26 million estimated cases in 1990 predicted to increase to 4.5 million by 2050. Varying models of care have been developed to improve outcomes following fragility hip fractures. Most of these care models embrace an interprofessional approach to care. Specialist orthopedic nurses play an important role in the management of fragility hip fracture patients and their contribution to the interprofessional health care team is an important predictor of patient outcomes.

ASSESSMENT OF THE PROBLEM

The Sunshine Coast Hospital and Health Service (SCHHS) is compromised of four hospitals in South East Queensland, Australia however only one large regional hospital provides specialist hip fracture services. Approximately, 350 older hip fracture patients present to the Sunshine Coast Hospital & Health Service (SCHHS) each year. We used Hospital Health round table (HHRT) data to identify and assess key performance care and management of hip fracture patient and outcomes at SCHHS. The HHRT is a nonprofit membership organisation of health services across Australia and New Zealand that aims to provide opportunity for Health Services to achieve best practice, collect analyse and publish information, identify ways to improve and promote collaboration and networking. Exemplars of best practice are also identified in the data so that organizations can adopt similar models of care. HHRT data identified underperformance in management of hip fracture patients in a number of quality indicators at the study site, including length of stay (LOS), time to surgery and relative stay index (RSI).

STRATEGIES FOR QUALITY IMPROVEMENT

Following review of HHRT data key stakeholders undertook a quality improvement project and formed the Hip Fracture Clinical Network Group (HFCNG). This was established in 2013 with the aim of improving outcomes and achieving key performance indicators for all elderly patients who sustain a hip fracture through active collaboration and regular communication between a broad group of key clinical stakeholders.

RESULTS OF THE QUALITY IMPROVEMENT PROJECT

Following the implementation of the initiative the Relative Stay Index reduced from 88% in 2012/13 to 78% in 2014/15, and the average LOS reduced from 10.4 days to 8.6 days. The percentage of patients receiving surgery within 2 days rose from 85% to 96%; demonstrating consistent outperformance of the time to surgery key performance indicator of 80%. The percentage of patients discharged to their place of usual residence increased from 45% to 54%. The rate of complications reduced slightly from 69% to 66%. Rates of hospital acquired anaemia reduced from 20.7% to 15%. Detection of delirium rose over the reporting period from 22% to 34%, enabling rapid management. We noted during this period that there was no corresponding increase in readmission rates for this group of patients. These data reflect improvement to clinical documentation and the appropriate identification of cognitive changes.

CONCLUSION

In this quality improvement report, we describe how key stakeholders were engaged to improve communication and collaboration, and how the use of a national benchmarking dataset enabled health care providers to identify care gaps and inconsistencies in clinical practice. This quality improvement project markedly improved collaboration, clinical practice and patient outcomes.

Impact of a Hospitalwide Quality Improvement Initiative on Emergency Department Throughput and Crowding Measures

BACKGROUND

This pre- and postintervention analysis evaluates the impact of a systemwide, comprehensive, executively supported quality improvement (QI) project on emergency department (ED) throughput measures and crowding in a large nonacademic community hospital.

METHODS

The two primary endpoints used to assess the impact of the project were (1) the percentage of all patients who were door-in to door-out in less than three hours and (2) the percentage of patients who left without being seen (LWBS). Secondary endpoints for throughput were mean door-in to door-out, door-in to physician, physician to disposition, and disposition to door-out times for all patients. Secondary endpoints for crowding were median disposition to door-out time of admitted patients and the percentage of admitted patients with a disposition to door-out time of ≥ one, two, and six hours.

RESULTS

A total of 666,640 patient visits were included in the primary endpoint analyses, with no patients excluded. The percentage of patients meeting the three-hour door-in to door-out goal after the QI project was 81.4%, versus 46.5% in the pre-QI group (difference, 34.9 percentage points; 95% confidence interval [CI] = 34.7-35.1; p < 0.0001). The postintervention LWBS rate was 0.49%, versus 4.00% in the pre-QI group (difference, 3.51 percentage points; 95% CI = 3.43-3.58; p < 0.0001). A total of 417,673 patient visits were screened for inclusion for the secondary endpoint analyses. The pre-QI and post-QI groups were also compared for secondary endpoints, and significant improvement was noted in all analyses.

CONCLUSION

This study suggests that a comprehensive systemwide and executively supported QI project can make sustained multiyear improvements in ED throughput and LWBS. Further research is needed to determine if this standardized set of changes can be generalized to other hospital systems.

Does Abnormal Laboratory Results Notification with the Short Message Service Shorten Length of Stay in the Pediatric Emergency Department Observation Unit?

BACKGROUND

A new age in communications began with the entry into use of cell phones and their applications. Cell phones and their various applications must be actively used in patient monitoring in the healthcare system.

INTRODUCTION

The purpose of this study was to determine the length of stay in the pediatric emergency department observation unit (PEDOU) based upon the notification of abnormal laboratory results (ALRs) via the short message service (SMS).

MATERIALS AND METHODS

Patients with ALRs notified through the SMS (April-May-June 2015: study period) were evaluated retrospectively, and those admitted to hospital after such notification were enrolled as the study group (SG). Patients presenting to the pediatric emergency department (April-May-June 2014: control period), whose ALRs were not notified through the SMS, and who were hospitalized for treatment, were enrolled as the control group (CG). Age, sex, length of stay in the PEDOU (min), admission diagnosis, and receiving department were recorded for both groups.

RESULTS

Number of patients monitored in the PEDOU was 8584 during the study period and 8507 during the control period (p = 0.27). Length of stay of patients monitored in the PEDOU during the control period (n = 8507) and study period (n = 8584) was 136.4 and 133.5 min, respectively (p = 0.92). One hundred forty-seven patients were enrolled as the SG and 154 as the CG. Length of stay in the PEDOU was 221.1 ± 86.9 (65-542) min in the CG and 154.8 ± 76.6 (15-442) min in the SG (p < 0.001, 95% confidence interval: 47.5-84.8).

CONCLUSIONS

Notification of ALRs through the SMS does not affect length of stay in the PEDOU. Use of this method reduces length of stay of patients who require more rapid hospitalization.

The association between discharge before noon and length of stay in medical and surgical patients

BACKGROUND

Discharging patients before noon is a key approach to improving bed utilization. Few data exist to describe whether patients are discharged earlier or their stay is extended to allow for an early discharge the next day.

OBJECTIVE

To determine if a discharge before noon (DCBN) is associated with length of stay (LOS).

DESIGN/SETTINGS/PATIENTS

Retrospective analysis of data from adult medical and surgical discharges from a single academic center from July 2012 through April 2015. We used a multivariable generalized linear model to evaluate the association between DCBN and LOS.

RESULTS

Of 38,365 hospitalizations, 6484 (16.9%) were discharged before noon, and the median LOS was 3.7 days. After adjustment, DCBN was associated with a longer LOS (adjusted odds ratio [OR]: 1.043, 95% confidence interval [CI]: 1.003-1.086). The association between longer LOS and DCBN was more pronounced in patients admitted emergently (n = 14,192, 37%) (adjusted OR: 1.14, 95% CI: 1.033-1.249).

CONCLUSIONS

Although we cannot discern whether discharges were delayed to achieve discharge before noon, earlier discharge was associated with a longer LOS, particularly among emergent admissions. Journal of Hospital Medicine 2015;11:859-861. © 2015 Society of Hospital Medicine.

An introduction to the Emergency Department Adult Clinical Escalation protocol: ED-ACE

PURPOSE OF THE STUDY

This study demonstrates how a participatory action research approach was used to address the challenge of the early and effective detection of the deteriorating patient in the ED setting. The approach enabled a systematic approach to patient monitoring and escalation of care to be developed to address the wide-ranging spectrum of undifferentiated presentations and the phases of ED care from triage to patient admission. This paper presents a longitudinal patient monitoring system, which aims to provide monitoring and escalation of care, where necessary, of adult patients from triage to admission to hospital in a manner that is feasible in the unique ED environment.

METHODS

An action research approach was taken to designing a longitudinal patient monitoring system appropriate for the ED. While the first draft protocol for post-triage monitoring and escalation was designed by a core research group, six clinical sites were included in iterative cycles of planning, action, reviewing and further planning. Reasons for refining the system at each site were collated and the protocol was adjusted accordingly before commencing the process at the next site.

RESULTS

The ED Adult Clinical Escalation longitudinal patient monitoring system (ED-ACE) evolved through iterative cycles of design and testing to include: (1) a monitoring chart for adult patients; (2) a standardised approach to the monitoring and reassessment of patients after triage until they are assessed by a clinician; (3) the ISBAR (I=Identify, S=Situation, B=Background, A=Assessment, R=Recommendation) tool for interprofessional communication relating to clinical escalation; (4) a template for prescribing a patient-specific monitoring plan to be used by treating clinicians to guide patient monitoring from the time the patient is assessed until when they leave the ED and (5) a protocol for clinical escalation prompted by single physiological triggers and clinical concern.

CONCLUSIONS

This tool offers a link in the 'Chain of Prevention' between the Manchester Triage System and ward-based early warning scores taking account of the importance of standardisation, while being sufficiently adaptable for the unique working environment and patient population in the ED.

After-hours medical deputising services: patterns of use by older people

OBJECTIVES

To examine how older people use an after-hours medical deputising service that arranges home visits by locum general practitioners; to identify differences in how people who live in the community and those who live in residential aged care facilities (RACFs) use this service.

DESIGN, SETTING AND PARTICIPANTS

Retrospective analysis of routinely collected administrative data from the Melbourne Medical Deputising Service (MMDS) for the 5-year period, 1 January 2008 - 31 December 2012. Data for older people (≥ 70 years old) residing in greater Melbourne and surrounding areas were analysed.

MAIN OUTCOME MEASURES

Numbers and rates of MMDS bookings for acute after-hours care, stratified according to living arrangements (RACF v community-dwelling residents).

RESULTS

Of the 357 112 bookings logged for older patients during 2008-2012, 81% were for RACF patients, a disproportionate use of the service compared with that by older people dwelling in the community. Most MMDS bookings resulted in a locum GP visiting the patient. During 2008-2012, the booking rate for RACFs increased from 121 to 168 per 1000 people aged 70 years or more, a 39% increase; the booking rate for people not living in RACFs increased from 33 to 40 per 1000 people aged 70 years or more, a 21% increase.

CONCLUSIONS

After-hours locum GPs booked through the MMDS mainly attended patients living in RACFs during 2008-2012. Further research is required to determine the reasons for differences in the use of locum services by older people living in RACFs and in the community.

Factors Associated With the Likelihood of Hospitalization Following Emergency Department Visits for Behavioral Health Conditions

OBJECTIVES

Behavioral health-related emergency department (ED) visits have been linked with ED overcrowding, an increased demand on limited resources, and a longer length of stay (LOS) due in part to patients being admitted to the hospital but waiting for an inpatient bed. This study examines factors associated with the likelihood of hospital admission for ED patients with behavioral health conditions at 16 hospital-based EDs in a large urban area in the southern United States.

METHODS

Using Andersen's Behavioral Model of Health Service Use for guidance, the study examined the relationship between predisposing (characteristics of the individual, i.e., age, sex, race/ethnicity), enabling (system or structural factors affecting healthcare access), and need (clinical) factors and the likelihood of hospitalization following ED visits for behavioral health conditions (n = 28,716 ED visits). In the adjusted analysis, a logistic fixed-effects model with blockwise entry was used to estimate the relative importance of predisposing, enabling, and need variables added separately as blocks while controlling for variation in unobserved hospital-specific practices across hospitals and time in years.

RESULTS

Significant predisposing factors associated with an increased likelihood of hospitalization following an ED visit included increasing age, while African American race was associated with a lower likelihood of hospitalization. Among enabling factors, arrival by emergency transport and a longer ED LOS were associated with a greater likelihood of hospitalization while being uninsured and the availability of community-based behavioral health services within 5 miles of the ED were associated with lower odds. Among need factors, having a discharge diagnosis of schizophrenia/psychotic spectrum disorder, an affective disorder, a personality disorder, dementia, or an impulse control disorder as well as secondary diagnoses of suicidal ideation and/or suicidal behavior increased the likelihood of hospitalization following an ED visit.

CONCLUSION

The block of enabling factors was the strongest predictor of hospitalization following an ED visit compared to predisposing and need factors. Our findings also provide evidence of disparities in hospitalization of the uninsured and racial and ethnic minority patients with ED visits for behavioral health conditions. Thus, improved access to community-based behavioral health services and an increased capacity for inpatient psychiatric hospitals for treating indigent patients may be needed to improve the efficiency of ED services in our region for patients with behavioral health conditions. Among need factors, a discharge diagnosis of schizophrenia/psychotic spectrum disorder, an affective disorder, a personality disorder, an impulse control disorder, or dementia as well as secondary diagnoses of suicidal ideation and/or suicidal behavior increased the likelihood of hospitalization following an ED visit, also suggesting an opportunity for improving the efficiency of ED care through the provision of psychiatric services to stabilize and treat patients with serious mental illness.

Improving discharge planning communication between hospitals and patients

BACKGROUND

A potential barrier to patient discharge from hospital is communication problems between the treating team and the patient or family regarding discharge planning.

AIM

To determine if a bedside 'Leaving Hospital Information Sheet' increases patient and family's knowledge of discharge date and destination and the name of the key clinician primarily responsible for team-patient communication.

METHODS

This article is a 'before-after' study of patients, their families and the interdisciplinary ward-based clinical team. Outcomes assessed pre-implementation and post-implementation of a bedside 'Leaving Hospital Information Sheet' containing discharge information for patients and families. Patients and families were asked if they knew the key clinician for team-patient communication and the proposed discharge date and discharge destination. Responses were compared with those set by the team. Staff were surveyed regarding their perceptions of patient awareness of discharge plans and the benefit of the 'Leaving Hospital Information Sheet'.

RESULTS

Significant improvement occurred regarding patients' knowledge of their key clinician for team-patient communication (31% vs 75%; P = 0.0001), correctly identifying who they were (47% vs 79%; P = 0.02), and correctly reporting their anticipated discharge date (54% vs 86%; P = 0.004). There was significant improvement in the family's knowledge of the anticipated discharge date (78% vs 96%; P = 0.04). Staff reported the 'Leaving Hospital Information Sheet' assisted with communication regarding anticipated discharge date and destination (very helpful n = 11, 39%; a little bit helpful n = 11, 39%).

CONCLUSIONS

A bedside 'Leaving Hospital Information Sheet' can potentially improve communication between patients, families and their treating team.

Impact of process improvements on measures of emergency department efficiency

OBJECTIVE

To study the operational impact of process improvements on emergency department (ED) patient flow. The changes did not require any increase in resources or expenditures.

METHODS

This was a 36-month pre- and post-intervention study to evaluate the effect of implementing process improvements at a community ED from January 2010 to December 2012. The intervention comprised streamlining triage by having patients accepted into internal waiting areas immediately after triage. Within the ED, parallel processes unfolded, and there was no restriction on when registration occurred or which health care provider a patient saw first. Flexible nursing ratios allowed nursing staff to redeploy and move to areas of highest demand. Last, demand-based physician scheduling was implemented. The main outcome was length of stay (LOS). Secondary outcomes included time to physician initial assessment (PIA), left-without-being-seen (LWBS) rates, and left-against-medical-advice (LAMA) rates. Segmented regression of interrupted time series analysis was performed to quantify the impact of the intervention, and whether it was sustained.

RESULTS

Patients totalling 251,899 attended the ED during the study period. Daily patient volumes increased 17.3% during the post-intervention period. Post-intervention, mean LOS decreased by 0.64 hours (p<0.005). LOS for non-admitted Canadian Triage and Acuity Scale 2 (-0.58 hours, p<0.005), 3 (-0.75 hours, p<0.005), and 4 (-0.32 hours, p<0.005) patients also decreased. There were reductions in PIA (43.81 minutes, p<0.005), LWBS (35.2%, p<0.005), and LAMA (61.9%, p<0.005).

CONCLUSION

A combination of process improvements in the ED was associated with clinically significant reductions in LOS, PIA, LWBS, and LAMA for non-resuscitative patients.

Implementing resilience engineering for healthcare quality improvement using the CARE model: a feasibility study protocol

BACKGROUND

Resilience engineering (RE) is an emerging perspective on safety in complex adaptive systems that emphasises how outcomes emerge from the complexity of the clinical environment. Complexity creates the need for flexible adaptation to achieve outcomes. RE focuses on understanding the nature of adaptations, learning from success and increasing adaptive capacity. Although the philosophy is clear, progress in applying the ideas to quality improvement has been slow. The aim of this study is to test the feasibility of translating RE concepts into practical methods to improve quality by designing, implementing and evaluating interventions based on RE theory. The CARE model operationalises the key concepts and their relationships to guide the empirical investigation.

METHODS

The settings are the Emergency Department and the Older Person's Unit in a large London teaching hospital. Phases 1 and 2 of our work, leading to the development of interventions to improve the quality of care, are described in this paper. Ethical approval has been granted for these phases. Phase 1 will use ethnographic methods, including observation of work practices and interviews with staff, to understand adaptations and outcomes. The findings will be used to collaboratively design, with clinical staff in interactive design workshops, interventions to improve the quality of care. The evaluation phase will be designed and submitted for ethical approval when the outcomes of phases 1 and 2 are known.

DISCUSSION

Study outcomes will be knowledge about the feasibility of applying RE to improve quality, the development of RE theory and a validated model of resilience in clinical work which can be used to guide other applications. Tools, methods and practical guidance for practitioners will also be produced, as well as specific knowledge of the potential effectiveness of the implemented interventions in emergency and older people's care. Further studies to test the application of RE at a larger scale will be required, including studies of other healthcare settings, organisational contexts and different interventions.

Federally Qualified Health Center Access and Emergency Department Use Among Children

OBJECTIVE

To determine whether increasing access to federally qualified health centers (FQHCs) in California was associated with decreased rates of emergency department (ED) use by children without insurance or insured by Medicaid.

METHODS

We combined several data sets to longitudinally analyze 58 California counties between 2005 and 2013. We defined access to FQHCs by county using 2 measures: FQHC sites per 100 square miles between 2005 and 2012 and percentage of Medicaid-insured and uninsured children served by FQHCs from 2008 to 2013. Our outcome was rates of ED use by uninsured or Medicaid-insured children ages 0 to 18 years. To determine the effect of changes in FQHC access on the outcome within a county over time, we used negative binomial models with county fixed effects and controls for preselected time-varying county characteristics and secular trends.

RESULTS

Increased geographic density of FQHC sites was associated with ≤18% lower rates of ED visits among Medicaid-insured children and ≤40% lower ED utilization among uninsured children (P = .05 and P < .01, respectively). However, the percentage of Medicaid-insured and uninsured children seen at FQHCs was not associated with any significant change in ED visit rates among Medicaid-insured or uninsured children.

CONCLUSIONS

Whereas increased geographic FQHC access was associated with lower rates of ED use by uninsured children, all other measures of FQHC access were not associated with statistically significant changes in pediatric ED use. These results provide community-level evidence that expanding FQHCs may have a limited impact on pediatric ED use, suggesting the need to explore additional factors driving ED utilization.

Association of hospital admission service structure with early transfer to critical care, hospital readmission, and length of stay

BACKGROUND

Hospital medical groups use various staffing models that may systematically affect care continuity during the admission process.

OBJECTIVE

To compare the effect of 2 hospitalist admission service models ("general" and "admitter-rounder") on patient disposition and length of stay.

DESIGN

Retrospective observational cohort study with difference-in-difference analysis.

SETTING

Large tertiary academic medical center in the United States.

PARTICIPANTS

Patients (n = 19,270) admitted from the emergency department to hospital medicine and medicine teaching services from July 2010 to June 2013.

INTERVENTIONS

Admissions to hospital medicine staffed by 2 different service models, compared to teaching service admissions.

MEASUREMENTS

Incidence of transfer to critical care within the first 24 hours of hospitalization, hospital and emergency department length of stay, and hospital readmission rates ≤30 days postdischarge.

RESULTS

The change of hospitalist services to an admitter-rounder model was associated with no significant change in transfer to critical care or hospital length of stay compared to the teaching service (difference-in-difference P = 0.32 and P = 0.87, respectively). The admitter-rounder model was associated with decreased readmissions compared to the teaching service on difference-in-difference analysis (odds ratio difference: -0.21, P = 0.01). Adoption of the hospitalist admitter-rounder model was associated with an increased emergency department length of stay compared to the teaching service (difference of +0.49 hours, P < 0.001).

CONCLUSIONS

Rates of transfer to intensive care and overall hospital length of stay between the hospitalist admission models did not differ significantly. The hospitalist admitter-rounder admission service structure was associated with extended emergency department length of stay and a decrease in readmissions.

Improving Emergency Department flow through optimized bed utilization

Over the last decade, patient volumes in the emergency department (ED) have grown disproportionately compared to the increase in staffing and resources at the Toronto Western Hospital, an academic tertiary care centre in Toronto, Canada. The resultant congestion has spilled over to the ED waiting room, where medically undifferentiated and potentially unstable patients must wait until a bed becomes available. The aim of this quality improvement project was to decrease the 90th percentile of wait time between triage and bed assignment (time-to-bed) by half, from 120 to 60 minutes, for our highest acuity patients. We engaged key stakeholders to identify barriers and potential strategies to achieve optimal flow of patients into the ED. We first identified multiple flow-interrupting challenges, including operational bottlenecks and cultural issues. We then generated change ideas to address two main underlying causes of ED congestion: unnecessary patient utilization of ED beds and communication breakdown causing bed turnaround delays. We subsequently performed seven tests of change through sequential plan-do-study-act (PDSA) cycles. The most significant gains were made by improving communication strategies: small gains were achieved through the optimization of in-house digital information management systems, while significant improvements were achieved through the implementation of a low-tech direct contact mechanism (a two-way radio or walkie-talkie). In the post-intervention phase, time-to-bed for the 90th percentile of high-acuity patients decreased from 120 minutes to 66 minutes, with special cause variation showing a significant shift in the weekly measurements.

Utilizing health analytics in improving the performance of healthcare services: A case study on a tertiary care hospital

Among the most common and chronic problems in the healthcare system worldwide is the crowding of emergency rooms (ER); leading to many serious complications. King Faisal Specialist Hospital and Research Center utilized health analytics methods to identify areas of deficiency and suggest potential improvements to ER performance. The project implemented solutions and monitored two indicators; ER length of stay (LOS), reflecting efficiency, and percentage of patients leaving without treatment, reflecting effectiveness of the ER. A retrospective analysis of 26,948 ER encounters in 2014 was done in January 2015. Analytics techniques were used to suggest process redesign based on results. Two recommendations were implemented; a Fast-Track for lower acuity ER patients and an internal waiting area, for those patients who can stay vertical and spare an ER bed. 32.8% of ER patients had lower acuity levels and less than 0.5% of them were admitted to the hospital. After implementing the two solutions, the total ER LOS was reduced from 20h in 2014 to less than 12h in 2016; 40% improvement. The percentages of patients left without being seen stayed around 3.5%, while the percentages of patients left before complete treatment was significantly reduced from 13.5% in 2014 to 5.5% in 2016. Consequently, the total percentage of patients left without treatment was reduced from 17% in 2014 to 9% in 2016, with 50% improvement. All other factors were the same, including numbers of ER visits, Patient Acuity Level, working staff, working hours, and the count of ER beds. Health analytics methods can be used to identify areas of deficiency, potential improvements, and recommend effective solutions to positively enhance ER performance. More solutions should be examined such as team triaging, patients palmar scanning, and placing a physician in triage. Additionally, more indicators should be monitored, such as the effectiveness of ER treatment-including the rates of revisits.

Reducing Hospital Readmissions via Optimization of Emergency Department Care

Over the past 5 years, early hospital readmissions have become a national focus. With several recent publications highlighting the high rates of early hospital readmissions among transplant recipients, more work is needed to identify risk factors and strategies for reducing unnecessary readmissions among this patient population. Although the American Society of Transplant Surgeons is advocating the exclusion of transplant recipients from the calculation of hospital readmission rates, the outcome of their advocacy efforts remains uncertain. One potential strategy for reducing early hospital readmissions is to critically examine care received by transplant recipients in the emergency department (ED), a critical pathway to readmission. As a starting point, research is needed to assess rates of ED presentation among transplant recipients, diagnostic algorithms, and communication among clinical teams. Mixed-methods studies that enhance understanding of system-level barriers to optimized evaluation and treatment of transplant recipients in the ED may lead to quality improvement interventions that reduce unnecessary readmissions, even if the rates of transplant recipients presenting to the ED remains high.

A 'busy day' effect on perinatal complications of delivery on weekends: a retrospective cohort study

Objective

To evaluate whether busy days on a labour and delivery unit are associated with maternal and neonatal complications of childbirth in California hospitals, accounting for weekday/weekend births.

Design

This is a population-based retrospective cohort study.

Setting

Linked vital statistics/patient discharge data for California births between 2009 and 2010 from the Office of Statewide Health Planning and Development.

Participants

All singleton, cephalic, non-anomalous California births between 2009 and 2010 (N=724 967).

Main outcomes

The key exposure was high daily obstetric volume, defined as giving birth on a day when the number of births exceeded the hospital-specific 75th percentile of daily delivery volume. Outcomes were a range of maternal and neonatal complications.

Results

Several maternal and neonatal complications were increased on high-volume days and weekends following adjustment for maternal demographics, annual hospital birth volume and teaching hospital status. For example, compared with low-volume weekdays, the odds of Apgar <7 on low-volume weekend days and high-volume weekend days were 11% (adjusted OR (aOR) 1.11, CI 1.03 to 1.21) and 29% higher (aOR 1.29, CI 1.10 to 1.52), respectively. High volume was associated with increased odds of neonatal seizures on weekdays (aOR 1.33, CI 1.01 to 1.71) and haemorrhage on weekends (aOR 1.11, CI 1.01 to 1.22). After accounting for between-hospital variation, weekend delivery remained significantly associated with increased odds of Apgar score <7, neonatal intensive care unit admission, prolonged maternal length of stay and the odds of neonatal seizures remained increased on high-volume weekdays.

Conclusions

Our findings suggest that weekend delivery is a consistent risk factor for a range of perinatal complications and there may be variability in how well hospitals handle surges in volume.

Utility of computed tomographic imaging of the cervical spine in trauma evaluation of ground-level fall

BACKGROUND

Computed tomography (CT) of the cervical spine (C-spine) is routinely ordered for low-risk mechanisms of injury, including ground-level fall. Two commonly used clinical decision rules (CDRs) to guide C-spine imaging in trauma are the National Emergency X-Radiography Utilization Study (NEXUS) and the Canadian Cervical Spine Rule for Radiography (CCR).

METHODS

Retrospective cross-sectional study of 3,753 consecutive adult patients presenting to an urban Level I emergency department who received C-spine CT scans were obtained over a 6-month period. The primary outcome of interest was prevalence of C-spine fracture. Secondary outcomes included fracture stability, appropriateness of imaging by NEXUS and CCR criteria, and estimated radiation dose exposure and costs associated with C-spine imaging studies.

RESULTS

Of the 760 patients meeting inclusion criteria, 7 C-spine fractures were identified (0.92% ± 0.68%). All fractures were identified by NEXUS and CCR criteria with 100% sensitivity. Of all these imaging studies performed, only 69% met NEXUS indications for imaging (50% met CCR indications). C-spine CT scans in patients not meeting CDR indications were associated with costs of $15,500 to $22,000 by NEXUS ($14,600-$25,600 by CCR) in this single center during the 6-month study period.

CONCLUSION

For ground-level fall, C-spine CT is overused. The consistent application of CDR criteria would reduce annual nationwide imaging costs in the United States by $6.8 to $9.6 million based on NEXUS ($6.4-$15.6 million based on CCR) and would reduce population radiation dose exposure by 0.8 to 1.1 million mGy based on NEXUS (0.7-1.9 million mGy based on CCR) if applied across all Level I trauma centers. Greater use of evidence-based CDRs plays an important role in facilitating emergency department patient management and reducing systemwide radiation dose exposure and imaging expenditures.

Increased door to admission time is associated with prolonged throughput for ED patients discharged home

BACKGROUND

Emergency Department (ED) service evaluations are typically based on surveys of discharged patients. Physicians/administrators benefit from data that quantifies system-based factors that adversely impact the experience of those who represent the survey cohort.

OBJECTIVE

While investigators have established that admitted patient boarding impacts overall ED throughput times, we sought to specifically quantify the relationship between throughput times for patients admitted (EDLOS) versus discharged home from the ED (DCLOS).

METHODS

We performed a prospective analysis of consecutive patient encounters at an inner-city ED. Variables collected: median daily DCLOS for ED patients, ED daily census, left without being seen (LWBS), median door to doctor, median room to doctor, and daily number admitted. Admitted patients divided into 2 groups based on daily median EDLOS for admits (<6 hours, ≥6 hours). Continuous variables analyzed by t-tests. Multivariate regression utilized to identify independent effects of the co-variants on median daily DCLOS.

RESULTS

We analyzed 24,127 patient visits. ED patient DCLOS was longer for patients seen on days with prolonged EDLOS (193.7 minutes, 95%CI 186.7-200.7 vs. 152.8, 144.9-160.5, P< .0001). Variables that were associated with increased daily median EDLOS for admits included: daily admits (P= 0.01), room to doctor time (P< .01), number of patients that left without being seen (P< .01). When controlling for the covariate daily census, differences in DCLOS remained significant for the ≥6 hours group (189.4 minutes, 95%CI 184.1-194.7 vs. 164.8, 155.7-173.9 (P< .0001).

CONCLUSION

Prolonged ED stays for admitted patients were associated with prolonged throughput times for patients discharged home from the ED.

High-sensitivity cardiac troponin testing in routine practice: economic and organizational advantages

Very seldom, if ever, a single laboratory test has provided such a paradigm shift in the managed care as cardiac troponin (cTn) testing. More than twenty years of improvements in test design and analytical features have contributed to revolutionize the clinical recommendations and guidelines, and the diagnosis of myocardial infarction (MI) is now highly dependent upon the kinetics of cTn within a suggestive clinical setting. Despite the advent of high-sensitivity cTn (HS-cTn) immunoassays has allowed a more accurate and timely diagnosis as well as a higher prognostic accuracy, the focus is now shifting on the most suitable algorithms and on a comprehensive approach to the clinical management of acute coronary syndrome (ACS). In this article we aim to discuss the implications of HS-cTn testing for ruling out and ruling in ACS. In the latter instance, main improvements are related to ACS diagnosis in women, in whom this pathology is still often underdiagnosed or misdiagnosed. A quick and accurate rule out will also regarded as a great advantage from both an organizational and economic standpoint. The advantages that will stem from this new approach have been recently assessed, and shortening of repeated testing 1 or 2 h from conventional algorithms entailing blood sampling at 3 and 6 h seems attainable. The larger benefits will definitely occur in clinical settings where the actual diagnosis rate of MI among patients with suspect ACS is lower and, consequently, the negative predictive value (NPV) of HS-cTn is the highest.
