Physician workload and the Canadian Emergency Department Triage and Acuity Scale: the Predictors of Workload in the Emergency Room (POWER) Study

The National Emergency Department Overcrowding Scale and Perceived Staff Workload: Evidence for Construct Validity in a Pediatric Setting

OBJECTIVE

The aim of the study is to determine if there is a correlation between perceived staff workload, measured by the NASA Task Load Index (TLX), and the National Emergency Department Overcrowding Scale (NEDOCS) in a pediatric ED.

METHODS

We collected staff questionnaires in a large, urban pediatric ED to assess perceived workload on each of six different TLX subscales, which we weighted evenly to create an overall estimate of workload. We evaluated the correlation between individual TLX responses and NEDOCS overall and by staff subgroup. Additionally, we analyzed: (1) the correlation between mean TLX responses and NEDOCS within a given hour and (2) the performance of a logistic regression model, using TLX as a predictor for "severely overcrowded," as measured by NEDOCS.

RESULTS

Four hundred one questionnaires between 6/2018 and 1/2019 demonstrated significant variation between concurrently collected TLX responses and an overall poor correlation between perceived workload and NEDOCS ( R2 0.096 [95% confidence interval, 0.048-0.16]). TLX responses by subgroups of fellows (n = 4, R2 0.96) and patient financial advisors (n = 15, R2 0.58) demonstrated the highest correlation with NEDOCS. Taking mean TLX responses within a given hour, during periods with NEDOCS >60 (extremely busy or overcrowded), a polynomial trend line matched the data best ( R2 0.638). On logistic regression, the TLX predicts "severely overcrowded" with an area under the curve of the receiver operating characteristic of 0.731.

CONCLUSIONS

NEDOCS does not have a strong correlation with individual responses on questionnaires of perceived workload for staff in a pediatric ED. NEDOCS, as a measure of overcrowding, may be better correlated with perceived workload during periods with elevated crowding or when interpreted categorically as yes/no "severely overcrowded".

Workflow and Short-Term Functional Outcomes in Simultaneous Acute Code Stroke Activation and Stroke Reperfusion Therapy

The burden of simultaneous acute code stroke activation (ACSA) is not known. We aim to assess the effect of simultaneous ACSA on workflow metrics and home time at 90 days in patients undergoing reperfusion therapies in the emergency department. Simultaneous ACSA was defined as code activation within 60 min of the arrival of any patient receiving intravenous thrombolysis, within 150 min of the arrival of any patient receiving endovascular thrombectomy, within 45 min of the arrival of any patient receiving no reperfusion therapies (based on mean local door-to-needle and door-to-puncture times). Simultaneous ACSA was further graded as 1, 2 and 3. We assessed workflow metrics as door-to-CT (DTC) time, in minutes, and functional outcome as home time at 90 days. A total of 2605 patients were assessed as ACSA at a mean ± SD activations of 130.8 ± 17.1/month and 859 (33%) were simultaneous. Among all ACSA, 545 (20.9%) underwent acute reperfusion therapy with a mean age of 70.6 ± 14.2 years, 45.9% (n = 254) were female with a median (IQR) NIHSS of 13 (8-18). A total of 220 (40.4%) patients underwent simultaneous treatments. The median DTC time, in minutes, was prolonged in grade 3 simultaneous ACSA (18 (13, 28)) compared to non-simultaneous ACSA (15 (11, 21) β = 0.23, p < 0.0001). There was no difference in the median home time at 90 days between the simultaneous (58, 0-84.5 days) and non-simultaneous (54, 0-85 days) patients. Simultaneous ACSA is frequent in patients receiving acute reperfusion therapies. An optimal workflow in high-volume centers may help mitigate the clinical and system burden associated with simultaneity.

Evaluating the Impact of Casino-Shifts on Patient Flow in an Emergency Department: A Pilot Study

OBJECTIVES

Demand for emergency services has resulted in an increased number of physicians experiencing burnout. Burnout rates amongst emergency medicine physicians consistently exceed that of other specialties, with shift work being a large contributor to the phenomenon. Casino-shift scheduling has addressed this issue in several emergency departments (EDs). Casino-shift scheduling is modeled around circadian rhythm theory which shows that anchor sleep helps to preserve circadian rhythm and normalize sleep patterns. To account for this, casino-shift models schedule overnight coverage with two six-hour shifts, to allow both physicians to obtain some sleep within the 01:00 to 06:00 am anchor period. While the benefits of the model have been demonstrated concerning physician well-being, there is a paucity of evidence assessing if this model has any effect on quality measures such as patient flow. Given the importance of patient flows to ED functioning, the objective of our study was to determine the effect of a casino-shift trial on overnight patient flow variables in a tertiary ED.

METHODS

We performed a retrospective analysis of administrative data for overnight (10:00 pm to 10:00 am) patient flow variables during a two-month casino-shift intervention period (September 9, 2019, to November 4, 2019) compared with a control period at an ED in Eastern Canada. We analyzed various measures of patient flow for patients presenting overnight between 10:00 pm to 10:00 am during the study period. Primary outcome measures were wait time (WT), length of stay (LOS), and admission rates.

RESULTS

Of the 19170 patient visits, 16787 met inclusion criteria. The median overnight WTs for the casino-shift intervention period were longer at 68 minutes (interquartile range (IQR) 31-154 minutes), compared with 51 minutes (IQR 21-104 minutes) in the control group. The LOS for the intervention was 217 minutes (IQR 132-358 minutes) compared with 195 minutes (IQR 112-336 minutes) for the control. There were 166 admissions/month during the trial, and 193 admissions/month during the 10-month control period.

CONCLUSIONS

In our study, our patient flow indicators of median WT and LOS were longer in the casino-shift intervention period by an absolute difference of 17 minutes and 22 minutes respectively. As a relatively new concept in emergency medicine scheduling, the impact of the casino-shift model on both well-being and ED efficiency warrants further investigation given the potential benefits to an occupation prone to burnout.

Assessing the reliability of pediatric emergency medicine billing code assignment for future consideration as a proxy workload measure

OBJECTIVES

Prediction of pediatric emergency department (PED) workload can allow for optimized allocation of resources to improve patient care and reduce physician burnout. A measure of PED workload is thus required, but to date no variable has been consistently used or could be validated against for this purpose. Billing codes, a variable assigned by physicians to reflect the complexity of medical decision making, have the potential to be a proxy measure of PED workload but must be assessed for reliability. In this study, we investigated how reliably billing codes are assigned by PED physicians, and factors that affect the inter-rater reliability of billing code assignment.

METHODS

A retrospective cross-sectional study was completed to determine the reliability of billing code assigned by physicians (n = 150) at a quaternary-level PED between January 2018 and December 2018. Clinical visit information was extracted from health records and presented to a billing auditor, who independently assigned a billing code-considered as the criterion standard. Inter-rater reliability was calculated to assess agreement between the physician-assigned versus billing auditor-assigned billing codes. Unadjusted and adjusted logistic regression models were used to assess the association between covariables of interest and inter-rater reliability.

RESULTS

Overall, we found substantial inter-rater reliability (AC2 0.72 [95% CI 0.64-0.8]) between the billing codes assigned by physicians compared to those assigned by the billing auditor. Adjusted logistic regression models controlling for Pediatric Canadian Triage and Acuity scores, disposition, and time of day suggest that clinical trainee involvement is significantly associated with increased inter-rater reliability.

CONCLUSIONS

Our work identified that there is substantial agreement between PED physician and a billing auditor assigned billing codes, and thus are reliably assigned by PED physicians. This is a crucial step in validating billing codes as a potential proxy measure of pediatric emergency physician workload.

Acuity-based rotational patient-to-physician assignment in an emergency department using electronic health records in triage

Emergency department (ED) operational metrics generated by a new acuity-based rotational patient-to-physician assignment (ARPA) algorithm are compared with those obtained with a simple rotational patient assignment (SRPA) system aimed only at an equitable patient distribution. The new ARPA method theoretically guarantees that no two physicians' assigned patient loads can differ by more than one, either partially (by acuity levels) or in total; whereas SRPA guarantees only the latter. The performance of the ARPA method was assessed in practice in the ED of the main public hospital (Hospital Compound of Navarra) in the region of Navarre in Spain. This ED attends over 140 000 patients every year. Data analysis was conducted on 9,063 ED patients in the SRPA cohort, and 8,892 ED patients in the ARPA cohort. The metrics of interest are related both to patient access to healthcare and physician workload distribution: patient length of stay; arrival-to-provider time; ratio of patients exceeding the APT target threshold; and range of assigned patients across physicians by priority levels. The transition from SRPA to ARPA is associated with improvements in all ED operational metrics. This research demonstrates that ARPA is a simple and useful strategy for redesigning front-end ED processes.

Comparison of emergency department workloads before and during the COVID-19 pandemic as assessed using relative value units

OBJECTIVE

This study aimed to assess and compare emergency department (ED) workloads by using relative value units (RVUs) before and during the COVID-19 pandemic.

METHODS

This retrospective observational study investigated the RVUs of a single ED from 2019 to 2021. We calculated the mean number of patients per day (PPD) for each year and selected the days when the number of patients was equal to the yearly mean PPD for each of the three years. We calculated the total RVUs per day and RVUs per patient and compared them.

RESULTS

We analyzed the RVUs of 12 days in 2019 (mean PPD, 88), 10 days in 2020 (mean PPD, 75), and 14 days in 2021 (mean PPD, 83). The mean of the total RVUs per day were as follows: 533,057.5±66,239.1 in 2019, 505,994.6±48,935.4 in 2020, and 634,219.6±64,024.2 in 2021 (P<0.001). The RVUs per patient in the three year-groups were significantly different (6,057.5±752.7 in 2019, 6,746.6±652.5 in 2020, and 7,641.2±771.4 in 2021; P<0.001). Post hoc analyses indicated that the total RVUs per day and the RVUs per patient in 2021 were significantly higher than in 2019 or 2020, although the mean PPD in 2019 was the highest.

CONCLUSION

Since the onset of the COVID-19 pandemic, the mean RVUs per patient have increased, suggesting that the workload per patient may also have increased in the regional emergency medical center.

Association Between Physicians' Workload and Prescribing Quality in One Tertiary Hospital in China

BACKGROUND

Alarming increasing trends in physician workload have attracted much attention in recent years. Heavy workload may compromise the quality of medication use. Previous studies have identified a series of factors contributing to inappropriate prescribing; however, there is no demonstrated evidence supporting an association between workload and the appropriateness of physicians' prescriptions in China. This study aimed to investigate the relationship between physician workload and prescription quality in a tertiary hospital in Beijing, China.

METHODS

Our study was a single-center, retrospective study, with all outpatient electronic health records extracted from hospital information system of a tertiary hospital in Beijing from July 1 to November 30, 2015. We used outpatient volume in each 5-hour shift as the measure of physician workload. The evaluation of prescribing quality was based on the Rational Drug Use System. Generalized linear models with a γ distribution and a log link were used to explore factors associated with inappropriate prescribing, and we undertook a series of robustness tests with respect to different exclusion criteria.

RESULTS

A total of 457,784 prescriptions from 502 physicians were included in the study. Physicians had an average workload of 34.3 (±19.8) patients per shift, and the mean rate of inappropriate prescribing per shift was 14.1% (±14.6%). Higher rates of inappropriate prescribing were associated with heavier workloads (P < 0.001). Physicians who worked in the afternoon, chief physicians, those working in surgical department, males, and those with more than 20-year experience had higher rates of inappropriate prescribing with increasing workload.

CONCLUSIONS

Heavier workload was associated with higher risk of prescribing inappropriately. It requires great efforts to determine optimal physician workloads and mitigate the potential adverse effects on the prescription quality.

How much time do doctors spend providing care to each child in the ED? A time and motion study

BACKGROUND

The total time per patient doctors spend providing care in emergency departments (EDs) has implications for the development of evidence-based ED staffing models. We sought to measure the total time taken by doctors to assess and manage individual paediatric patients presenting to two EDs in the Western Cape, South Africa and to compare these averages to the estimated benchmarks used regionally to calculate ED staffing allocations.

METHODS

We conducted a cross-sectional, observational study applying time and motion methodology, using convenience sampling. Data were collected over a 5-week period from 11 December 2015 to 18 January 2016 at Khayelitsha District Hospital Emergency Centre and Tygerberg Hospital Paediatric Emergency and Ambulatory Unit. We assessed total doctor time for each patient stratified by acuity level using the South African Triage Scale.

RESULTS

Care was observed for a total of 100 patients. Median age was 21 months (IQR 8-55). Median total doctor time per patient (95% CI) was 31 (22 to 38), 39 (31 to 63), 48 (32 to 63) and 96 (66 to 122) min for triage categories green, yellow, orange and red, respectively. Median timing was significantly higher than the estimated local benchmark for the lowest acuity 'green' triage category (31 min (22 to 38) vs 15 min; p=0.001) and the highest acuity 'red' category (96 min (66 to 122) vs 50 min; p=0.002).

CONCLUSION

Doctor time per patient increased with increasing acuity of triage category and exceeded estimated benchmarks for the highest and lowest acuities. The distinctive methodology can easily be extended to other settings and populations.

Emergency Department Mean Physician Time per Patient and Workload Predictors ED-MPTPP

One key element for emergency department (ED) staff calculation is the mean physician time per patient (MPTPP) and its influencing factors. The aims of this study were measuring the MPTPP, identifying factors with significant influence on the MPTPP, and developing a model to predict the MPTPP. This study was a prospective trial conducted at the ED of a university hospital in Germany. The MPTPP was measured with a specifically developed app. The influence of different factors on MPTPP were first tested in univariate analysis. Then, all significant factors were used in a multivariant regression model to minimize collinearities and to develop a prediction model. In total, 202 patients treated by 32 different physicians were observed within one year. The MPTPP was 47 min (standard deviation: 34 min). Relevant factors influencing the MPTPP were treatment area, Emergency Severity Index (ESI) triage level, guiding symptom category, and physician level (all p < 0.001). This model predicted 45% of the variance in the MPTPP (p < 0.001), which corresponds to a large effect size. We developed an effective prediction model for ED MPTPP, resulting in an MPTPP of 47 min. Future studies are needed to validate our model, which could serve as a benchmark for other EDs where the MPTPP is not available.

Consistency of triage scores by presenting complaint pre- and post-implementation of a real-time electronic triage decision support tool

OBJECTIVE

eCTAS is a real-time electronic decision-support tool designed to standardize the application of the Canadian Triage and Acuity Scale (CTAS). This study addresses the variability of CTAS score distributions across institutions pre- and post-eCTAS implementation.

METHODS

We used population-based administrative data from 2016-2018 from all emergency departments (EDs) that had implemented eCTAS for 9 months. Following a 3-month stabilization period, we compared 6 months post-eCTAS data to the same 6 months the previous year (pre-eCTAS). We included triage encounters of adult (≥17 years) patients who presented with 1 of 16 pre-specified, high-volume complaints. For each ED, consistency was calculated as the absolute difference in CTAS distribution compared to the average of all included EDs for each presenting complaint. Pre-eCTAS and post-eCTAS change scores were compared using a paired-samples t-test. We also assessed if eCTAS modifiers were associated with triage consistency.

RESULTS

There were 363,214 (183,231 pre-eCTAS, 179,983 post-eCTAS) triage encounters included from 35 EDs. Triage scores were more consistent (P < 0.05) post-eCTAS for 6 (37.5%) presenting complaints: chest pain (cardiac features), extremity weakness/symptoms of cerebrovascular accident, fever, shortness of breath, syncope, and hyperglycemia. Triage consistency was similar pre- and post-eCTAS for altered level of consciousness, anxiety/situational crisis, confusion, depression/suicidal/deliberate self-harm, general weakness, head injury, palpitations, seizure, substance misuse/intoxication, and vertigo. Use of eCTAS modifiers was associated with increased triage consistency.

CONCLUSIONS

eCTAS increased triage consistency across many, but not all, high-volume presenting complaints. Modifier use was associated with increased triage consistency, particularly for non-specific complaints such as fever and general weakness.

[Physician staffing and shift work schedules : Concepts for emergency and intensive care medicine]

Human resource development is a key factor for a successful management of Intensive Care Units (ICU) and Emergency Departments (ED). It comprises the processes of recruiting and retaining employees. The present article offers strategies how the optimal manning level in ICUs and EDs can be determined and highlights the importance of active management of well being in acute care units. The manning level can be determined by using the work place method which is the common method for ICUs. For the EDs a method based on the specific times which are needed for patient care in relation to the intensity of care is more appropriate. This method needs to integrate the patient number per hour, the time needed per patient, and the defined service level particularly with respect to the time to be seen by a physician. For detailed staff calculation, complex mathematical models are needed (e.g. Erlang formula). The resulting manning level needs then to be distributed on the various shifts. Additional resources are needed for observation units and additional tasks like management tasks etc. Retainment of employees is only possible when the working field remains attractive over many years. While a structured and competence based education is of utmost importance in the beginning of a carrier, attractive rooster plans and the compatibility between work and private life, becomes more important when the specialisation has been achieved.

Interrater Reliability, Accuracy, and Triage Time Pre- and Post-implementation of a Real-Time Electronic Triage Decision-Support Tool

STUDY OBJECTIVE

The electronic Canadian Triage and Acuity Scale (eCTAS) is a real-time electronic triage decision-support tool designed to improve patient safety and quality of care by standardizing the application of the Canadian Triage and Acuity Scale (CTAS). The objective of this study is to determine interrater agreement of triage scores pre- and post-implementation of eCTAS.

METHODS

This was a prospective, observational study conducted in 7 emergency departments (EDs), selected to represent a mix of triage documentation practices, hospital types, and patient volumes. A provincial CTAS auditor observed triage nurses in the ED pre- and post-implementation of eCTAS and assigned an independent CTAS score in real time. Research assistants independently recorded triage time. Interrater agreement was estimated with κ statistics with 95% confidence intervals (CIs).

RESULTS

A total of 1,491 individual triage assessments (752 pre-eCTAS, 739 post-implementation) were audited during 42 7-hour triage shifts (21 pre-eCTAS, 21 post-implementation). Exact modal agreement was achieved for 567 patients (75.4%) pre-eCTAS compared with 685 patients (92.7%) triaged with eCTAS. With the auditor's CTAS score as the reference, eCTAS significantly reduced the number of patients over-triaged (12.0% versus 5.1%; Δ 6.9; 95% CI 4.0 to 9.7) and under-triaged (12.6% versus 2.2%; Δ 10.4; 95% CI 7.9 to 13.2). Interrater agreement was higher with eCTAS (unweighted κ 0.89 versus 0.63; quadratic-weighted κ 0.93 versus 0.79). Median triage time was 312 seconds (n=3,808 patients) pre-eCTAS and 347 seconds (n=3,489 patients) with eCTAS (Δ 35 seconds; 95% CI 29 to 40 seconds).

CONCLUSION

A standardized, electronic approach to performing triage assessments improves both interrater agreement and data accuracy without substantially increasing triage time.

Understanding better how emergency doctors work. Analysis of distribution of time and activities of emergency doctors: a systematic review and critical appraisal of time and motion studies

BACKGROUND

Optimising the efficiency and productivity of senior doctors is critical to ED function and delivery of safe patient care. Time and motion studies (TMS) can allow quantification of how these doctors spend their working time, identify inefficiencies in the current work processes and provide insights into improving working conditions, and enhancing productivity. Three questions were addressed: (1) How do senior emergency doctors spend their time in the ED? (2) How much of their time is spent on multitasking? (3) What is the number of tasks completed per hour?

METHODS

The literature was systematically searched for TMS of senior emergency doctors. We searched for articles published in peer-reviewed journals in English language from 1998 to 2018 in the following databases: MEDLINE, EMBASE, Scopus, Web of Science and Cochrane. Studies were assessed for methodological quality using evidence-based quality criteria relevant for TMS including duration of observation, observer bias, Hawthorne effect and whether the task classification acknowledged any previous existing schemes. A narrative synthesis approach was followed.

RESULTS

Fourteen TMS were included. The studies were liable to several biases including observer and Hawthorne bias. Overall, the time spent on direct face-to-face contact with the patient accounted for at least around 25%-40% of the senior doctors' time. The remaining time was mostly spent on indirect clinical care such as communication (8%-44%), documentation (10%-28%) and administrative tasks (2%-20%). The proportion of time spent on multitasking ranged from 10% to 23%. When reported, the number of tasks performed per hour was generally high.

CONCLUSION

The review revealed that senior doctors spent a large percentage of their time on direct face-to-face contact with patients. The review findings provided a grounded understanding of how senior doctors spent their time in the ED and could be useful in implementing improvements to the emergency care system.

Use of Free, Open Access Medical Education and Perceived Emergency Medicine Educational Needs Among Rural Physicians in Southwestern Ontario

Free, open access medical education (FOAM) has the potential to revolutionize continuing medical education, particularly for rural physicians who practice emergency medicine (EM) as part of a generalist practice. However, there has been little study of rural physicians' educational needs since the advent of FOAM. We asked how rural physicians in Southwestern Ontario obtained their continuing EM education. We asked them to assess their perceived level of comfort in different areas of EM. To understand how FOAM resources might serve the rural EM community, we compared their responses with urban emergency physicians. Responses were collected via survey and interview. There was no significant difference between groups in reported use of FOAM resources. However, there was a significant difference between rural and urban physicians' perceived level of EM knowledge, with urban physicians reporting a higher degree of confidence for most knowledge categories, particularly those related to critical care and rare procedures. This study provides the first description of EM knowledge and FOAM resource utilization among rural physicians in Southwestern Ontario. It also highlights an area of educational need -- that is, critical care and rare procedures. Future work should address whether rural physicians are using FOAM specifically to improve their critical care and procedural knowledge. As well, because of the generalist nature of rural practice, future work should clarify whether there is an opportunity cost to rural physicians' knowledge of other clinical domains if they chose to focus more time on continuing education in critical care EM.

Prehospital Application of the Canadian Triage and Acuity Scale by Emergency Medical Services

OBJECTIVES

Triage is fundamental to emergency patient assessment. Effective triage systems accurately prioritize patients and help predict resource utilization. CTAS is a validated five-level triage score utilized in Emergency Departments (EDs) across Canada and internationally. Historically CTAS has been applied by triage nurses in EDs. Observational evidence suggests that the CTAS might be implemented reliably by paramedics in the prehospital setting. This is the first system-wide assessment of CTAS interrater reliability between paramedics and triage nurses during clinical practice.

METHODS

Variables were extracted from hospital and EMS databases. EMS providers determined CTAS on-scene, CTAS pre-transport, and CTAS on-arrival at hospital for each patient (N=14,378). The hospital arrival EMS CTAS (CTAS arrival ) score was compared to the initial nursing CTAS score (CTAS initial ) and the final nursing CTAS score (CTAS final ) incuding nursing overrides. Interrater reliability between ED CTAS initial and EMS CTAS arrival scores was assessed. Interrater reliability between ED CTAS final and EMS CTAS arrival scores, as well as proportion of patient encounters with perfect or near-perfect agreement, were evaluated.

RESULTS

Our primary outcome, interrater reliability [kappa=0.437 (p<0.001, 95% CI 0.421-0.452)], indicated moderate agreement. EMS CTAS arrival and ED CTAS initial scores had an exact or within one point match 84.3% of the time. The secondary interrater reliability outcome between hospital arrival EMS CTAS (CTAS arrival ) score and the final ED triage CTAS score (CTAS final ) showed moderate agreement with kappa =0.452 (p<0.001, 95% CI 0.437-0.466).

CONCLUSIONS

Interrater reliability of CTAS scoring between triage nurses and paramedics was moderate in this system-wide implementation study.

Emergency physician workload modeling

Background:

A variety of models are used by hospitals, provincial governments, and departments of emergency medicine to “predict” the number of physician hours of coverage necessary to staff emergency departments. These models have arisen to meet specific requirements—some for the purpose of determining hourly rates of compensation, others to determine the amount of funding that will be provided to “purchase” physician coverage, and others to determine the number of hours of coverage necessary to maintain patient waits within “acceptable” limits. All such models have their strengths and weaknesses and have been criticized as not reflecting the “real” needs of any given department.

Objective:

In the article that follows, a review of existing models is presented, annotating their strengths and weaknesses to derive the characteristics of an “ideal” workload model.

Conclusion:

None of the models currently used to measure emergency department workload can be relied on to accurately predict the number of staffed hours necessary. Models that may achieve this objective are suggested.

Safety in numbers: lack of evidence to indicate the number of physicians needed to provide safe acute medical care

Patient safety in hospital is dependent on a multitude of factors. Recent reports into the failings of healthcare organisations in the UK have highlighted low staffing levels as a significant factor. There is research into the impact of nurse-to-patient ratios on patient safety, but our literature search found little published data that would allow healthcare providers to define a minimum number of physician staff and skills mix that would assure safety in the largest hospital specialty: unscheduled (acute) medicine. Future work should focus on the evaluation of existing data on hospital mortality rates and physician staffing levels as well as on empirical time and motion studies to ascertain the resources required to undertake safe medical care at times of peak demand.

Pilot study comparing sepsis management with and without electronic clinical practice guidelines in an academic emergency department

BACKGROUND

Sepsis is a potentially life-threatening condition that requires urgent management in an Emergency Department (ED). Evidence-based guidelines for managing sepsis have been developed; however, their integration into routine practice is often incomplete. Care maps may help clinicians meet guideline targets more often.

OBJECTIVES

To determine if electronic clinical practice guidelines (eCPGs) improve management of patients with severe sepsis and septic shock (SS/SS).

METHODS

The impact of an eCPG on the management of patients presenting with SS/SS over a 3-year period at a tertiary care ED was evaluated using retrospective case-control design and chart review methods. Cases and controls, matched by age and sex, were chosen from an electronic database using physician sepsis diagnoses. Data were compared using McNemar tests or paired t-tests, as appropriate.

RESULTS

Overall, 51 cases and controls were evaluated; the average age was 62 years, and 60% were male. eCPG patients were more likely to have a central venous pressure and central venous oxygen saturation measured; however, lactate measurement, blood cultures, and other investigations were similarly ordered (all p > 0.05). The administration of antibiotics within 3 h (63% vs. 41%; p = 0.03) and vasopressors (45% vs. 20%; p = 0.02) was more common in the eCPG group; however, use of corticosteroids and other interventions did not differ between the groups. Overall, survival was high and similar between groups.

CONCLUSION

A sepsis eCPG experienced variable use; however, physicians using the eCPG achieved more quality-of-care targets for SS/SS. Strategies to increase the utilization of eCPGs in Emergency Medicine seem warranted.

Triage During Mass Gatherings

Triage is a complex process and is one means for determining which patients most need access to limited resources. Triage has been studied extensively, particularly in relation to triage in overcrowded emergency departments, where individuals presenting for treatment often are competing for the available stretchers. Research also has been done in relation to the use of prehospital and field triage during mass-casualty incidents and disasters.

In contrast, scant research has been done to develop and test an effective triage approach for use in mass-gathering and mass-participation events, although there is a growing body of knowledge regarding the health needs of persons attending large events. Existing triage and acuity scoring systems are suboptimal for this unique population, as these events can involve high patient presentation rates (PPR) and, occasionally, critically ill patients. Mass-gathering events are dangerous; a higher incidence of injury occurs than would be expected from general population statistics.

The need for an effective triage and acuity scoring system for use during mass gatherings is clear, as these events not only create multiple patient encounters, but also have the potential to become mass-casualty incidents. Furthermore, triage during a large-scale disaster or mass-casualty incident requires that multiple, local agencies work together, necessitating a common language for triage and acuity scoring.

In reviewing existing literature with regard to triage systems that might be employed for this population, it is noted that existing systems are biased toward traumatic injuries, usually ignoring mitigating factors such as alcohol and drug use and environmental exposures. Moreover, there is a substantial amount of over-triage that occurs with existing prehospital triage systems, which may lead to misallocation of limited resources. This manuscript presents a review of the available literature and proposes a triage system for use during mass gatherings that also may be used in the setting of mass-casualty incidents or disaster responses.
