Validation of an emergency triage scale for obstetrics and gynaecology: a prospective study

The design of an Obstetric Telephone Triage Guideline (OTTG): a mixed method study

BACKGROUND

Clarifying the dimensions and characteristics of obstetric telephone triage is important in improving the quality of services in the health system because researchers can evaluate the effectiveness of treatment, care and diagnostic measures in the form of obstetric telephone triage by developing a guideline. Therefore, this study aimed to design an Obstetric Telephone Triage Guideline (OTTG) using a mixed-method study.

METHODS

The present study was carried out using an exploratory sequential mixed method study in two qualitative and quantitative phases. An inductive-deductive approach was also used to determine the concept of obstetric telephone triage. In this respect, a qualitative study and a literature review were used in the inductive and deductive stages, respectively. Moreover, the validity of the developed guideline was confirmed based on experts' opinions and results of the AGREE II tool.

RESULTS

The guideline included the items for evaluating the severity of obstetric symptoms at five levels including "critical", "urgent", "less urgent", "no urgent", and "recommendations". The validity of the guideline was approved at 96%, 95%, 97%, 95%, 93%, and 100% for six dimensions of AGREE II including scope and purpose, stakeholder involvement, the rigor of development, clarity of presentation, applicability, and editorial independence, respectively.

CONCLUSION

The OTTG is a clinically comprehensive, easy-to-use, practical, and valid tool. This guideline is a standardized tool for evaluating the severity of symptoms and determining the urgency for obstetrics triage services. By using this integrated and uniform guideline, personal biases can be avoided, leading to improved performance and ensuring that patients are not overlooked. Additionally, the use of OTTG promotes independent decision-making and reduces errors in triage decision-making.

Improving assessment of acute obstetric patients - introducing a Swedish obstetric triage system

BACKGROUND

Failure to identify severely ill obstetric patients seeking acute care, and hence delaying treatment, can lead to maternal morbidity and mortality. Triage is the prioritization of patients seeking emergency care, based on clinical decision-making tools assessing medical urgency. While triage has been applied in general emergency medicine for 30 years, there are only a few obstetric triage systems (OTS) and obstetric triage has hitherto been unknown in Sweden. Obstetric triage is more complex than general triage since both mother and fetus require assessment, and pregnancy-related physiological changes must be taken into account. This paper aims to describe the development and an initial evaluation of the first OTS in Sweden.

METHODS

A multidisciplinary team surveyed reasons to seek acute obstetric care and the current patient flow at the largest obstetric unit in Scandinavia, Sahlgrenska University Hospital, Gothenburg, Sweden, with about 10,000 deliveries/year. A semi-structured literature review on obstetric triage was undertaken. Based on the survey and the literature review the first Swedish OTS was developed and implemented. Patient satisfaction was followed by electronical questionnaires. Initial validity evaluation was performed, defined by the system's ability to identify patients with need for hospital admission, stratified by acuity level.

RESULTS

The Gothenburg Obstetrical Triage System (GOTS) addresses the patient to one of five acuity levels based on both vital signs and 14 chief complaint algorithms. It entails recommendations for initial procedures of care as well as an acuity form for documentation. Initial evaluation of the system indicates good correlation between need for admission and acuity level. The implementation has provided the staff with an improved medical overview of the patients and patient flow and enabled the unit to monitor emergency care in a structured way. Implementation came along with increased patient and staff satisfaction.

CONCLUSION

The GOTS is the first OTS developed in and for Sweden and implementation has improved management of obstetric patients seeking acute care. Patients are now prioritized according to level of acuity and the time to assessment and treatment of severely ill patients can be structurally evaluated. Both patients and staff express improved satisfaction with obstetric triage.

An interrater reliability study on the Gothenburg obstetric triage system- a new obstetric triage system

BACKGROUND

Triage, identifying patients with critical and time-sensitive disorders, is an integrated process in general emergency medicine. Obstetric triage is more specialised, requiring assessment of both woman, fetus and labour status. Failure to identify severely ill obstetric patients has repeatedly led to maternal morbidity and mortality. Reliable triage systems, adapted to obstetric patients as well as local conditions, are thus essential. The study aims to assess the interrater reliability (IRR) of the Gothenburg Obstetric Triage System (GOTS).

METHODS

Midwives (n = 6) and registered nurses with no experience in managing obstetric patients (n = 7), assessed 30 paper cases based on actual real-life cases, using the GOTS. Furthermore, a reference group consisting of two midwives and two obstetricians, with extensive experience in obstetric care, determined the correct triage level in order to enable analysis of over- and undertriage. IRR was assessed, both with percentage of absolute agreement and with intra-class correlation coefficients (ICC) with 95% confidence intervals (CI).

RESULTS

A total of 388 assessments were performed, comprising all five levels of acuity in the GOTS. Absolute agreement was found in 69.6% of the assessments. The overall IRR was good, with a Kappa value of 0.78 (0.69-0.87, 95% CI) for final triage level. Comparison with reference group assessments established that over- and undertriage had occurred in 9% and 21% of the cases, respectively. The main reasons for undertriage were "not acknowledging abnormal vital sign parameters" and "limitations in study design".

CONCLUSION

The GOTS is a reliable tool for triaging obstetric patients. It enables a standardized triage process unrelated to the assessors' level of experience in assessing and managing obstetric patients and is applicable for triaging obstetric patients presenting for emergency care at obstetric or emergency units.

The impact of implementing a psychiatric emergency hotline on the reduction of acute hospitalizations in a Swiss tertiary hospital

BACKGROUND

Inpatient treatment is not the most beneficial treatment setting for many patients with psychiatric disorders and overcrowding is a recurrent problem for psychiatric hospitals. Therefore, it is important to develop strategies to limit avoidable inpatient treatment. This study sought to evaluate the impact of an emergency hotline that was developed to better manage psychiatric patients, particularly for identifying those requiring a hospital admission.

METHODS

This pre-post intervention quality improvement study compared changes in the management of psychiatric patients' admission before and after the introduction of an emergency hotline where a specialist in psychiatry examines all inpatient referral from private practitioners. Main outcomes were the change in proportion of hospital admissions after referral from a private practitioner before and within 3 months after the intervention. Secondary outcomes were the average length of hospital stay, proportion of non-voluntary admission, the time required for triage and the impact of the intervention on treatments' costs. Fisher's Exact test was used to test the primary hypothesis of difference in the proportion of hospitalized patients before and after introduction of the emergency hotline. Secondary outcomes were tested with Student's t-test for continuous variables and Fishers's Exact test for proportions.

RESULTS

Among 45 admission requests from private practitioners during the 3 months after introduction of the new emergency hotline, 25 (55.6%) were accepted as inpatient treatment, while 20 (44%) were redirected to more appropriate outpatient treatments. There was a highly significant difference from the baseline period during which all 34 requests were accepted (44% vs 100%, p < 0.001). In addition, for the patients hospitalized after the introduction of the emergency hotline there was a trend-level reduction of the average length of stay (9.32 days vs 17.35 days).

CONCLUSION

Implementation of an emergency hotline manage by a specialist in psychiatry for admissions to acute psychiatric wards is feasible and simple to use. Importantly, it allows to significantly decrease the proportion of hospitalizations. Additional studies are needed to assess the generalizability of these exploratory results to other health care settings.

Reliability of Dutch Obstetric Telephone Triage

Background

Safety and efficiency of emergency care can be optimized with a triage system which uses urgency to prioritize care. The Dutch Obstetric Telephone Triage System (DOTTS) was developed to provide a basis for assessing urgency of unplanned obstetric care requests by telephone. Reliability and validity are important components in evaluating such (obstetric) triage systems.

Objective

To determine the reliability of Dutch Obstetric Telephone Triage, by calculating the inter-rater and intra-rater reliability.

Methods

To evaluate the urgency levels of DOTTS by testing inter-rater and intra-rater reliability, 90 vignettes of possible requests were developed. Nineteen participants, from hospitals where DOTTS had been implemented, rated in two rounds a set of ten vignettes. The five urgency levels and five presenting symptoms had an equal spread and had to be entered in accordance with DOTTS per vignette. Urgency levels were dichotomized into high urgency and intermediate urgency. Inter-rater reliability was rated as degree of agreement between two different participants with the same vignette. Intra-rater reliability was rated as agreement by the same participants at different moments in time. The degree of inter-rater and intra-rater reliability was tested using weighted Cohen’s Kappa and ICC.

Results

The agreement of urgency level between participants in accordance with predefined urgency level per vignette was 90.5% (95% CI 87.5–93.6) [335 of 370]. Agreement of urgency level between participants was 88.5% (95% CI 84.9–93.0) [177 of 200] and 84.9% (95% CI 78.3–91.4) after re-rating [101 of 119]. Inter-rater reliability of DOTTS expressed as Cohen’s Kappa was 0.77 and as ICC 0.87; intra-rater reliability of DOTTS expressed as Cohen’s Kappa was 0.70 and as ICC 0.82.

Conclusion

Inter-rater and intra-rater reliability of DOTTS showed substantial correlation, and is comparable to other studies. Therefore, DOTTS is considered reliable.

Implementation of an obstetric triage decision aid into a maternity assessment unit and emergency department

BACKGROUND

The obstetric triage decision aid (OTDA) consists of 10 common pregnancy complaints with key signs and symptoms generating a triage score based on targeted questioning responses. It was developed to provide a standardised approach for obstetric triage conducted by midwives and emergency nurses as neither professional group are expert in the triage of pregnant and postpartum women.

AIM

To evaluate implementation of the OTDA into an emergency department (ED) and maternity assessment unit (MAU).

METHODS

The OTDA was introduced to the ED and MAU of a hospital in Australia. A range of implementation strategies were utilised and assessed by pre and post staff survey, and a three-month post-audit of unscheduled maternity presentations. The primary outcome was adoption rate of the OTDA. Secondary outcomes were staff confidence and waiting times. Analyses were undertaken using SPSS (v24). Paired analysis was conducted on staff surveys.

RESULTS

There were a total of 2829 unscheduled presentations: ED (n=708) and MAU (n=2121), 88.1% were triaged using the OTDA, used more in the MAU than the ED (93.2% vs 72.7%; p<.001). In the MAU, women seen within 15min of arrival improved significantly from 42.0% to 78.0%. There was improvement in the self-rated confidence (p=.002) and competence (p=.004) by nurses and midwives to conduct obstetric triage.

CONCLUSION

The introduction of the OTDA required different approaches to change practice. There were improvements in staff self-rated confidence and competence, a reduction in clinical risk associated with under-triage in the ED and improved prioritisation of care in the MAU.

Validation of Dutch Obstetric Telephone Triage System: A Prospective Validation Study

Objective and Purpose

A triage system that prioritizes care according to medical urgency has a favorable effect on safety and efficiency of emergency care. The Dutch obstetric telephone triage system is comparable to physical triage systems. It consists of five urgency levels: resuscitation and life threatening (U1), emergency (U2), urgent (U3), non-urgent (U4) and self-care advice (U5). The purpose of this study was to determine the diagnostic and external validity of the Dutch obstetric telephone triage system in obstetric emergency care.

Patients and Methods

The validity of the Dutch obstetric telephone triage system was studied in a prospective observational study in four hospitals. Diagnostic validity of usual care was determined by comparing the assigned urgency level of the Dutch obstetric telephone triage system with a reference standard. This reference standard was obtained by face-to-face clinical assessment in hospital following telephone triage. Clinical follow-up after assessment was also recorded. For statistical analyses, urgency levels were dichotomized into high urgency (U1, U2) and intermediate urgency (U3, U4). Self-care advice (U5) could not be studied because these patients were not referred to hospital.

Results

In total, 983 cases (U1-U4) across the four hospitals were included, 625 (64%) cases were categorized as high urgency and 358 (36%) as intermediate urgency. The Dutch obstetric telephone triage system’s urgency level agreed with the reference standard in 53% (n=525; 95% CI 50–57%). According to the reference standard the Dutch obstetric telephone triage system had undertriage in 16% (n=160) and overtriage in 30% (n=298) of the cases. Sensitivity for high urgency was 76% (95% CI 72–80), specificity 49% (95% CI 44–53). Positive predictive value and negative predictive value were 60% (95% CI 56–63) and 67% (95% CI 62–72), respectively. After clinical assessment, urgent care was needed in 8.7% (n=31) of the intermediate-urgency cases, none of these cases were life threatening situations.

Conclusion

DOTTS shows an acceptable diagnostic validity with room for improvement.

Symptom-Based Dispatching in an Emergency Medical Communication Centre: Sensitivity, Specificity, and the Area under the ROC Curve

Measuring the performance of emergency medical dispatch tools used in paramedic-staffed emergency medical communication centres (EMCCs) is rarely performed. The objectives of our study were, therefore, to measure the performance and accuracy of Geneva's dispatch system based on symptom assessment, in particular, the performance of ambulance dispatching with lights and sirens (L&S) and to measure the effect of adding specific protocols for each symptom. Methods: We performed a prospective observational study including all emergency calls received at Geneva's EMCC (Switzerland) from 1 January 2014 to 1 July 2019. The risk levels selected during the emergency calls were compared to a reference standard, based on the National Advisory Committee for Aeronautics (NACA) scale, dichotomized to severe patient condition (NACA ≥ 4) or stable patient condition (NACA < 4) in the field. The symptom-based dispatch performance was assessed using a receiver operating characteristic (ROC) curve. Contingency tables and a Fagan nomogram were used to measure the performance of the dispatch with or without L&S. Measurements were carried out by symptom, and a group of symptoms with specific protocols was compared to a group without specific protocols. Results: We found an acceptable area under the ROC curve of 0.7474, 95%CI (0.7448-0.7503) for the 148,979 assessments included in the study. Where the severity prevalence was 21%, 95%CI (20.8-21.2). The sensitivity of the L&S dispatch was 87.5%, 95%CI (87.1-87.8); and the specificity was 47.3%, 95%CI (47.0-47.6). When symptom-specific assessment protocols were used, the accuracy of the assessments was slightly improved. Conclusions: Performance measurement of Geneva's symptom-based dispatch system using standard diagnostic test performance measurement tools was possible. The performance was found to be comparable to other emergency medical dispatch systems using the same reference standard. However, the implementation of specific assessment protocols for each symptom may improve the accuracy of symptom-based dispatch systems.

Effects of environmental distractors on nurse emergency triage accuracy: a pilot study protocol

Background

The clinical decisions of emergency department triage nurses need to be of the highest accuracy. However, studies have found repeatedly that these nurses over- or underestimate the severity of patient health conditions. This has major consequences for patient safety and patient flow management. Workplace distractors such as noise and task interruptions have been pointed to as factors that might explain this inaccuracy. The use of a serious game reproducing the work environment during triage affords the opportunity to explore the impact of these distractors on nurse emergency triage accuracy, in a safe setting.

Methods/design

A pilot study with a factorial design will be carried out to test the acceptability and feasibility of a serious game developed specifically to simulate the triage process in emergency departments and to explore the primary effects of distractors on nurse emergency triage accuracy. Eighty emergency nurses will be randomized into four groups: three groups exposed to different distractors (A, noise; B, task interruptions; C, noise and task interruptions) and one control group. All nurses will have to complete 20 clinical vignettes within 2 h. For each vignette, a gold standard assessment will be determined by experts. Pre-tests will be conducted with clinicians and certified emergency nurses to evaluate the appeal of the serious game.

Discussion

Study results will inform the design of large-scale investigations and will help identify teaching, training, and research areas that require further development.

Obstetric Telephone Triage

Objective

Little is known about obstetric telephone triage: the methods used to prioritize the severity of symptoms of obstetric emergency and other unplanned care requests originating by telephone. In large-scale obstetric units, there is a need for an evidence-based triage guideline. The aim of this study was to develop an obstetric guideline for telephonic triage.

Design Setting and Participants

A multi-phase multi-center study was performed with consecutive drafts of the triage guideline using four focus groups, four observations of training sessions and two expert consultations based on the Delphi method. The study was performed in ten hospitals in the Netherlands. The obstetric care professionals involved were gynecologists, midwives, nurses, doctor's assistants, team managers and application managers. After each focus group, each observation and each expert consultation, an interpretative analysis was undertaken. Based on these analyses, the obstetric telephone triage guideline was drafted.

Measurements and Results

The designed guideline describes the primary symptoms presented, five prioritization categories and several descriptors. Consensus (>90%) was reached during the second expert consultation. Fifty-seven (91.9%) participants stated that the obstetric telephone triage guideline was clinically complete, correct, user-friendly and well designed, and 61 (98.4%) participants judged that the newly designed triage guideline was ready to use in daily practice.

Key-Conclusions and Implications for Practice

An evidence-based guideline for obstetric telephone triage was developed through a multi-phase multi-center study with all stakeholders. The guideline was found to be clinically complete, correct, well-designed and user-friendly. It provides a uniform and concrete basis for assessing the severity of the symptoms of obstetric emergency and other unplanned care requests originating by telephone. It also provides a good basis to further develop this evidence-based guideline for telephone triage by continuous registration of all calls.

Factors influencing the implementation of obstetric triage: a qualitative study

OBJECTIVE

To identify factors influencing the OB triage implementation in Iran DESIGN: Qualitative study of conventional content analysis SETTING: A teaching tertiary referral hospital in Ahvaz, Khuzestan, Iran PARTICIPANTS: 37 professional midwives, nurses, gynecologists, and specialists of emergency medicine, and 6 patients MEASUREMENTS AND FINDINGS: Semi-structured interviews were conducted individually and face-to-face. Interviews were audio recorded, transcribed, and analyzed using conventional content analysis. Four overarching categories and nine themes emerged from the content analysis of the interviews and observations. Overarching categories were the guideline, individual, cultural and social context, and organization. The development and structure were themes of the guideline. Knowledge, attitudes, and behaviors were related to the category of individuals. The cultural and social context included cultural and social changes. Implementation and monitoring strategies and executive infrastructure were organizational themes. Participants had differences and similarities in understanding influencing factors.

CONCLUSION

The guideline, individual, cultural and social context, and organization were key factors influencing the OB triage implementation in Iran. Some variety was detected between the different occupational groups' perceptions of influencing factors. Providing human resources and training and empowerment of them was the most significant factor influencing, which was acknowledged by almost all participants in all occupational groups.

IMPLICATION FOR PRACTICE

Identifying the influencing factors from the perspective of all stakeholders can improve the process of OB triage implementation by eliminating barriers and enhancing facilitators.

Exploring the concept and structure of obstetric triage: a qualitative content analysis

BACKGROUND

Obstetric triage is a new idea, so the design and implementation of it requires identification of its concept and structure. The aim of this qualitative study was to explore the concept and structure of the obstetric triage in Iran.

METHODS

The purposive sampling was done and it continued until reaching the theoretical saturation. Thirty-seven semi-structured interviews were conducted individually and face-to-face. Interviews were audio recorded, transcribed, and analyzed using conventional content analysis.

RESULTS

Two themes, 8 main categories, and 16 subcategories emerged from the content analysis of the interviews and observations. The themes were the concept and structure of obstetric triage. The concept of obstetric triage consisted of three categories of nature, process, and philosophy of obstetric triage. The structure of obstetric triage included five categories of assessment criteria, emergency grading, determining the appropriate location for patient guidance, initiation of diagnostic and therapeutic measures, and timeframe for initial assessment and reassessment.

CONCLUSION

Findings highlighted that obstetric triage is a process with a dual and dynamic nature. This process involves clinical decision making to prioritize the pregnant mother and her fetus based on the severity and acuity of the disease in order to allocate medical resources and care for providing appropriate treatment at the right time and place to the right patient. The results of this study could be used for the design and implementation of the obstetric triage system.

The development and validation of an obstetric triage acuity index: a mixed-method study

Background: There is uncertainty about the applicability of developed country triage scales in the developing population.Objective: To develop and validate an obstetric triage scale in Iran.Methods: This exploratory sequential mixed-method study was conducted on experienced gynecologists, emergency medicine, midwives, and nurses as evaluators, and pregnant or parturient women as sample. Development of obstetric triage acuity index was done using qualitative study and literature review. Thirty-two evaluators in two rounds evaluated the clinical impact score, content validity ratio, and content validity index. The tool performance was compared with a standard reference in 415 women. The association of urgency levels with hospitalization, resource utilization, and emergency department length of stay were assessed in 599 women. Five midwives independently double-triaged 234 convenience women to estimate inter-rater reliability.Results: Out of 191 items in the initial draft, 9 (4.7%) items in the face validity, 33 (18.1%) in the first, and 5 (3.2%) in the second content validity round were removed because not meeting the expected thresholds. Nine items added based on evaluators' suggestions. Finally, total items had a kappa above 0.74, and S-CVI/Ave, S-CVI/UA were 0.99 and 0.86, respectively. There was a significant correlation between the two tools (r = 0.661, p < 0). Level 1 mothers had a higher chance of using ≥ 2 resources (OR = 16.4, 95% CI = 2.06-129.98) and hospitalization (OR = 18.0, 95% CI = 3.96-81.51) compared to the level 5, after adjusting for gestational age/postpartum, and referral method. Sensitivity, specificity, and accuracy of the scale in predicting hospitalization were 74.8% (95% CI = 69.73-79.49), 80.8% (95% CI = 73.60-86.74), and 76.7% (72.67-80.48), respectively. The over and under-triage rates were 6.1% and 17.1%, respectively. The absolute agreement inter-raters was 86.8%, and the linear weighted kappa was 0.86 (95% CI = 0.81-0.91).Conclusion: The designed OB triage scale showed good validity and reliability in the tertiary teaching hospital. Studying this tool at lower levels, non-educational, and public hospitals are recommended for external validity testing.

Obstetric and fetal triage

Triage in healthcare is sorting patients by acuity to prioritize them for full evaluation. Standardizing this process with the use of triage acuity classification tools has been shown to improve patient flow and quality of care in the emergency department. The American College of Obstetricians and Gynecologists recommends that pregnant women be triaged based on acuity, rather than time of arrival, and that obstetric triage acuity scales can serve as templates for use at the facility level. Three obstetric triage acuity scales developed in North America are reviewed and the implementation of one in a system with 40 birth hospitals is described. Use of obstetric triage acuity scales resulted in timelier initial assessment and decreased wait times. Acuity, volume, and trends data helped improve nurse and provider staffing in triage units. These findings support the promise of obstetric triage acuity scales to promote efficient care.

Obstetric triage systems: a systematic review of measurement properties (Clinimetric)

BACKGROUND

Since labor and delivery units often serve as emergency units for pregnant women, the use of obstetric triage systems with poor or inadequate quality can lead to unintended consequences such as over and under-triage and so a waste of humans and financial resources. Therefore, this systematic review was conducted to evaluate the measurement properties of obstetric triage tools.

METHODS

PubMed, EMBASE, and Medline were searched to identify studies in October 2018 and were updated in May 2019. The risk of bias COSMIN checklist was used to evaluate the quality of the studies. The quality of every measurement property was appraised by the update criteria of COSMIN. Evidence quality was judged using the modified GRADE approach.

RESULTS

A total of 444 studies were retrieved in initial search. Six studies evaluating 4 tools were included in this study. All the included studies reported only content validity and reliability. The quality of evidence varied from very low to moderate. The quality of content validity and reliability of the included tools was sufficient except for the reliability of the maternal-fetal triage index. The obstetric triage acuity scale (OTAS) was found to have higher reliability than other tools.

CONCLUSIONS

Due to insufficient evidence, the conclusions about the quality of measurement properties of each obstetric triage tool may be uncertain. This review emphasizes the necessity for further studies with robust methodological quality on the measurement properties of obstetric triage tools.

The Quality of the Maternity Triage Process: a Qualitative Study

Introduction:

There is no consensus on what the bases and criteria are for the dynamic process of maternity triage. Properly performing the maternity triage process requires reliable data to ensure the correct implementation of this process and the identification of existing deficiencies, and find strategies to modify, improve and enhance the quality of this process.

Objective:

The present study was conducted to explain the quality of the maternity triage process.

Methods:

The present qualitative study performed a directed content analysis on 19 maternity triage service providers and key informants selected through purposive sampling. The data were collected through semi-structured interviews in 2018 and analyzed using directed content analysis based on the Donabedian’s model. The accuracy and rigor of the qualitative data were then investigated and confirmed.

Results:

The participants identified the most important factors affecting the quality of the services provided in maternity triage as two categories of measures and care, and interactions and communication. The category of measures and care included two subcategories of examinations and obtaining a medical history.

Conclusion:

The present study comprehensively identified different dimensions of the quality of maternity triage services at different levels. The participants identified the quality of the maternity triage process as a multi-dimensional and important concept. Different dimensions of the maternity triage process are recommended that be addressed when designing and implementing maternity triage guidelines and instructions so as to maintain the quality of this process and satisfy their needs.

Pitfalls in the triage and evaluation of patients with suspected acute ethanol intoxication in an emergency department

Acute ethanol intoxication (AEI) is frequent in emergency departments (EDs). These patients are at risk of mistriage, and to leave the ED without being seen. This study's objective was to describe the process and performance of triage and trajectory for patients with suspected AEI. Retrospective, observational study on adults admitted with a suspected AEI within 1 year at the ED of an urban teaching hospital. Data on the triage process, patients' characteristics, and their ED stay were extracted from electronic patient records. Predictors for leaving without being seen were identified using logistic regression analyzes. Of 60,488 ED patients within 1 year, 776 (1.3%) were triaged with suspected AEI. This population was young (mean age 38), primarily male (64%), and professionally inactive (56%). A large proportion were admitted on weekends (45%), at night (46%), and arrived by ambulance (85%). The recommendations of our triage scale were entirely respected in a minority of cases. In 22.7% of triage situations, a triage reason other than "alcohol abuse/intoxication" (such as suicidal ideation, head trauma or other substance abuse) should have been selected. Nearly, half of the patients (49%) left without being seen (LWBS). This risk was especially high amongst men (OR 1.56, 95% CI 1.12-2.19), younger patients (< 26 years of age; OR 1.97, 95% CI 1.16-3.35), night-time admissions (OR 1.97, 95% CI 1.16-3.35), and patients assigned a lower emergency level (OR 2.32, 95% CI 1.58-3.42). Despite a standardized triage protocol, patients admitted with suspected AEI are at risk of poor assessment, and of not receiving optimal care.

Impact of a patient-flow physician coordinator on waiting times and length of stay in an emergency department: A before-after cohort study

OBJECTIVE

Overcrowding is common in most emergency departments (ED). Despite the use of validated triage systems, some patients are at risk of delayed medical evaluation. The objective of this study was to assess the impact of a patient-flow physician coordinator (PFPC) on the proportion of patients offered medical evaluation within time limits imposed by the Swiss Emergency Triage Scale (SETS) and on patient flow within the emergency department of a teaching urban hospital.

METHODS

In this before-after retrospective cohort study, we compared the proportions of patients who received their first medical contact within SETS-imposed time limits, mean waiting times before first medical consultation, mean length of stay, and number of patients who left without being seen by a physician, between two periods before and after introducing a PFPC. The PFPC was a senior physician charged with quickly assessing in the waiting area patients who could not immediately be seen and managing patient flow within the department.

RESULTS

Before introducing the PFPC position, 33,605 patients were admitted, versus 36,288 after. Introducing a PFPC enabled the department to increase the proportion of patients seen within the SETS-imposed time limits from 60.1% to 69.0% (p <0.0001). Waiting times until first medical consultation were reduced on average by 27.7 minutes (95% confidence interval [95% CI]: 25.9-29.5, p < .0001). No significant differences were observed as to length of stay or number of patients who left without being seen between the two study periods.

CONCLUSIONS

Introducing a physician dedicated to managing patient flow enabled waiting times until first medical consultation to be reduced, yet had no significant benefit for patient flow within the ED, nor did it reduce the number of patients who left without being seen.
