Management of women referred to an acute gynecology unit: impact of an ultrasound-based model of care

The feasibility of introducing early pregnancy assessment unit in Nigerian hospitals: A pilot study from a private hospital in Enugu, Southeast Nigeria

Background

Early pregnancy assessment unit (EPAU) is a dedicated unit that provides specialist care such as definitive ultrasonographic and biochemical assessment to women who have or have had vaginal bleeding or pain before 16 weeks of pregnancy. Such patients usually have a positive pregnancy test with a scan showing pregnancy of an unknown location, previous ectopic pregnancy, recurrent miscarriages, or previous molar pregnancy. Such a holistic and prompt approach leads to better outcome in the management of women with early pregnancy and other complications.

Aim

This study aimed to describe the diagnosis and outcome of early pregnancy pain and bleeding, managed by rapid ultrasonographic and biochemical assessments by a dedicated gynecological team in a private hospital to determine the feasibility of establishing early pregnancy assessment units (EPAUs) in Nigeria.

Materials and Methods

This is a cross-sectional study of eligible cases of early pregnancy bleeding and pain in a private gynecological hospital in Enugu, Nigeria.

Results

During the 9-year study period, 160 women with early pregnancy pain or bleeding were analyzed. The mean age of the participants was 32.3 ± 7.2 years, and they were mostly multipara (68.7%) and Christians and of the Igbo tribe (91.3%). The final diagnosis after clinical and radiological evaluations showed that the majority had miscarriages (82.5%), while 17.5% had ectopic gestations. All the participants had their definitive diagnosis and treatment within 24 hours of presentation. There was no recorded case of maternal death.

Conclusion

EPAUs are feasible in a Nigerian setting provided that trained, dedicated staff and equipment are provided.

Bleeding related hospitalizations and mortality in England 2014-2019

Acute bleeding is common and associated with increased morbidity and mortality. Epidemiological studies evaluating trends in bleeding-related hospitalisations and mortality are important as they have potential to guide resource allocation and service provision, however, despite this literature evaluating the national burden and annual trends are lacking. Our objective was to report the national burden and incidence of bleeding-related hospitalisation and mortality.This was a population-based review of all people in England between 2014 and 2019 either admitted to an acute care ward of a National Health Service (NHS) English hospital, or who died. Admissions and deaths were required to have a primary diagnosis of significant bleeding.There was a total of 3,238,427 hospitalisations with a mean of 539,738 ± 6033 per year and 81,264 deaths with a mean of 13,544 ± 331 per year attributable to bleeding. The mean annual incident rate for bleeding-related hospitalisations was 975 per 100,000 patient years and for mortality was 24.45. Over the study period there was a significant 8.2% reduction in bleeding related deaths (χ² test for trend 91.4, p < 0.001). A direct relationship between increasing age and incidence of bleeding-related hospitalisation and mortality was seen.Bleeding remains a common cause of hospitalisation and death. The reduction in bleeding related mortality requires further investigation. This data may serve to guide future interventions designed to reduce bleeding-related morbidity and mortality.

Differences in the organisation of early pregnancy units and the effect of senior clinician presence, volume of patients and weekend opening on emergency hospital admissions: Findings from the VESPA Study

OBJECTIVE

To determine whether the participation of consultant gynaecologists in delivering early pregnancy care results in a lower rate of acute hospital admissions.

DESIGN

Prospective cohort study and emergency hospital care audit; data were collected as part of the national prospective mixed-methods VESPA study on the "Variations in the organization of EPAUs in the UK and their effects on clinical, Service and PAtient-centred outcomes".

SETTING

44 Early Pregnancy Assessment Units (EPAUs) across the UK randomly selected in balanced numbers from eight pre-defined mutually exclusive strata.

PARTICIPANTS

6606 pregnant women (≥16 years old) with suspected first trimester pregnancy complications attending the participating EPAUs or Emergency Departments (ED) from December 2016 to July 2017.

EXPOSURES

Planned and actual senior clinician presence, unit size, and weekend opening.

MAIN OUTCOME MEASURES

Unplanned admissions to hospital following any visit for investigations or treatment for first trimester complications as a proportion of women attending EPAUs.

RESULTS

205/6397 (3.2%; 95% CI 2.8-3.7) women were admitted following their EPAU attendance. The admission rate among 44 units ranged from 0% to 13.7% (median 2.8). Neither planned senior clinician presence (p = 0.874) nor unit volume (p = 0.247) were associated with lower admission rates from EPAU, whilst EPAU opening over the weekend resulted in lower admission rates (p = 0.027). 1445/5464 (26.4%; 95%CI 25.3 to 27.6) women were admitted from ED. There was little evidence of an association with planned senior clinician time (p = 0.280) or unit volume (p = 0.647). Keeping an EPAU open over the weekend for an additional hour was associated with 2.4% (95% CI 0.1% to 4.7%) lower odds of an emergency admission from ED.

CONCLUSIONS

Involvement of senior clinicians in delivering early pregnancy care has no significant impact on emergency hospital admissions for early pregnancy complications. Weekend opening, however, may be an effective way of reducing emergency admissions from ED.

Sporadic miscarriage: evidence to provide effective care

The physical and psychological effect of miscarriage is commonly underappreciated. The journey from diagnosis of miscarriage, through clinical management, to supportive aftercare can be challenging for women, their partners, and caregivers. Diagnostic challenges can lead to delayed or ineffective care and increased anxiety. Inaccurate diagnosis of a miscarriage can result in the unintended termination of a wanted pregnancy. Uncertainty about the therapeutic effects of interventions can lead to suboptimal care, with variations across facilities and countries. For this Series paper, we have developed recommendations for practice from a literature review, appraisal of guidelines, and expert group discussions. The recommendations are grouped into three categories: (1) diagnosis of miscarriage, (2) prevention of miscarriage in women with early pregnancy bleeding, and (3) management of miscarriage. We recommend that every country reports annual aggregate miscarriage data, similarly to the reporting of stillbirth. Early pregnancy services need to focus on providing an effective ultrasound service, as it is central to the diagnosis of miscarriage, and be able to provide expectant management of miscarriage, medical management with mifepristone and misoprostol, and surgical management with manual vacuum aspiration. Women with the dual risk factors of early pregnancy bleeding and a history of previous miscarriage can be recommended vaginal micronised progesterone to improve the prospects of livebirth. We urge health-care funders and providers to invest in early pregnancy care, with specific focus on training for clinical nurse specialists and doctors to provide comprehensive miscarriage care within the setting of dedicated early pregnancy units.

Variations in the organisation of and outcomes from Early Pregnancy Assessment Units: the VESPA mixed-methods study

Background

Early pregnancy complications are common and account for the largest proportion of emergency work in gynaecology. Although early pregnancy assessment units operate in most UK acute hospitals, recent National Institute of Health and Care Excellence guidance emphasised the need for more research to identify configurations that provide the optimal balance between cost-effectiveness, clinical effectiveness and service- and patient-centred outcomes [National Institute for Health and Care Excellence (NICE). Ectopic Pregnancy and Miscarriage: Diagnosis and Initial Management. URL: http://guidance.nice.org.uk/CG154 (accessed 23 March 2016)].

Objectives

The primary aim was to test the hypothesis that the rate of hospital admissions for early pregnancy complications is lower in early pregnancy assessment units with high consultant presence than in units with low consultant presence. The key secondary objectives were to assess the effect of increased consultant presence on other clinical outcomes, to explore patient satisfaction with the quality of care and to make evidence-based recommendations about the future configuration of UK early pregnancy assessment units.

Design

The Variations in the organisations of Early Pregnancy Assessment Units in the UK and their effects on clinical, Service and PAtient-centred outcomes (VESPA) study employed a multimethods approach and included a prospective cohort study of women attending early pregnancy assessment units to measure clinical outcomes, an economic evaluation, a patient satisfaction survey, qualitative interviews with service users, an early pregnancy assessment unit staff survey and a hospital emergency care audit.

Setting

The study was conducted in 44 early pregnancy assessment units across the UK.

Participants

Participants were pregnant women (aged ≥ 16 years) attending the early pregnancy assessment units or other hospital emergency services because of suspected early pregnancy complications. Staff members directly involved in providing early pregnancy care completed the staff survey.

Main outcome measure

Emergency hospital admissions as a proportion of women attending the participating early pregnancy assessment units.

Methods

Data sources – demographic and routine clinical data were collected from all women attending the early pregnancy assessment units. For women who provided consent to complete the questionnaires, clinical data and questionnaires were linked using the women’s study number. Data analysis and results reporting – the relationships between clinical outcomes and consultant presence, unit volume and weekend opening hours were investigated using appropriate regression models. Qualitative interviews with women, and patient and staff satisfaction, health economic and workforce analyses were also undertaken, accounting for consultant presence, unit volume and weekend opening hours.

Results

We collected clinical data from 6606 women. There was no evidence of an association between admission rate and consultant presence (p = 0.497). Health economic evaluation and workforce analysis data strands indicated that lower-volume units with no consultant presence were associated with lower costs than their alternatives.

Limitations

The relatively low level of direct consultant involvement could explain the lack of significant impact on quality of care. We were also unable to estimate the potential impact of factors such as scanning practices, level of supervision, quality of ultrasound equipment and clinical care pathway protocols.

Conclusions

We have shown that consultant presence in the early pregnancy assessment unit has no significant impact on key outcomes, such as the proportion of women admitted to hospital as an emergency, pregnancy of unknown location rates, ratio of new to follow-up visits, negative laparoscopy rate and patient satisfaction. All data strands indicate that low-volume units run by senior or specialist nurses and supported by sonographers and consultants may represent the optimal early pregnancy assessment unit configuration.

Future work

Our results show that further research is needed to assess the potential impact of enhanced clinical and ultrasound training on the performance of all disciplines working in early pregnancy assessment units.

A Framework Proposal for Quality and Safety Measurement in Gynecologic Emergency Care

Potentially life-threatening gynecologic emergencies are high-risk conditions that may serve as a useful framework to improve quality and safety in emergency care.

OBJECTIVE:

To define and assess the prevalence of potentially life-threatening gynecologic emergencies among women presenting for acute pelvic pain for the purpose of developing measures to audit quality of care in emergency departments.

METHODS:

We conducted a mixed-methods multicenter study at gynecologic emergency departments in France and Belgium. A modified Delphi procedure was first conducted in 2014 among health care professionals to define relevant combinations of potentially life-threatening conditions and near misses in the field of gynecologic emergency care. A prospective case–cohort study in the spring of 2015 then assessed the prevalence of these potentially life-threatening emergencies and near misses among women of reproductive age presenting for acute pelvic pain. Women in the case group were identified at 21 participating centers. The control group consisted of a sample of women hospitalized for acute pelvic pain not caused by a potentially life-threatening condition and a 10% random sample of outpatients.

RESULTS:

Eight gynecologic emergencies and 17 criteria for near misses were identified using the Delphi procedure. Among the 3,825 women who presented for acute pelvic pain, 130 (3%) were considered to have a potentially life-threatening condition. The most common diagnoses were ectopic pregnancies with severe bleeding (n=54; 42%), complex pelvic inflammatory disease (n=30; 23%), adnexal torsion (n=20; 15%), hemorrhagic miscarriage (n=15; 12%), and severe appendicitis (n=6; 5%). The control group comprised 225 hospitalized women and 381 outpatients. Diagnostic errors occurred more frequently among women with potentially life-threatening emergencies than among either hospitalized (odds ratio [OR] 1.7, 95% CI 1.1–2.7) or outpatient (OR 14.7, 95% CI 8.1–26.8) women in the control group. Of the women with potentially life-threatening conditions, 26 met near-miss criteria compared with six with not potentially life-threatening conditions (OR 25.6, 95% CI 10.9–70.7).

CONCLUSIONS:

Potentially life-threatening gynecologic emergencies are high-risk conditions that may serve as a useful framework to improve quality and safety in emergency care.

Guidelines for minimal report in gynaecologic sonography: Are they useful for emergency department resident physicians?

OBJECTIVES

This study aimed to evaluate the impact of Collège National des Gynécologues et Obstétriciens Français (CNGOF) guidelines on the minimal sonographic reports generated by emergency department resident physicians.

MATERIAL AND METHODS

This prospective observational study was conducted in the gynaecologic emergency unit of a teaching hospital from November 2016 to May 2017. We analysed sonographic reports generated by residents during gynaecological emergencies before and after training on the minimal report standards. An analysis of the evaluated items was carried out. We also compared residents according to their specialities and seniority.

RESULTS

A total of 240 reports were analysed, 120 before and 120 after the training. Half of the reports concerned women with an early pregnancy while the others concerned women with negative hCG. All residents significantly improved their practice after the training, as shown by the increase in ratings of the evaluated items (38 % before training vs 44.8 % after, p < 0.01). General practitioners had greater improvement (48.1 % of evaluated items), whereas older residents reported fewer items before or after the training (43.5 %) than younger residents. Finally, all residents improved their practice with a conclusion that followed the guidelines in 92.5 % of cases (versus 68.3 % before the training; p < 0.01).

CONCLUSION

Training on the CNGOF minimal sonographic report guidelines significantly improved the emergency sonographic reports generated by residents. Wider dissemination of this training, particularly to young residents, would probably improve the quality of sonographic reports performed at gynaecological emergencies.

Implementing a community model of early pregnancy care

Background

In the UK Early Pregnancy Assessment Units (EPAUs) are usually situated alongside hospital maternity and gynaecology services. In June 2018, the Oxford EPAU relocated from the John Radcliffe Hospital to a community clinic. This is to our knowledge, the UK’s first community-based EPAU. This change was inspired by our patient feedback describing the co-location of the EPAU with maternity services as distressing.

Methods

Following the introduction of the community EPAU we developed a database to capture information on the patients seen in the clinic. This is a retrospective observational study of a single cohort of patients attending the clinic over an 8 month period. Data was collected from 1st July 2018 to 28th February 2019. This data included clinical, safety and patient experience outcomes.

Results

Two thousand nine hundred and twenty patient episodes were recorded, 1,932 were new patients. Mean waiting time to be seen in clinic was 1.3 days. When miscarriage was confirmed 48.6% chose conservative management, 19.9% chose medical management, and 31.5% chose surgical management. The mean rate of ambulance transfers to hospital was 3.1 per month. Of all patients seen in EPAU 32 had unplanned admissions, which accounted for 2.7% of all patients seen in EPAU. Patient feedback questionnaires have been consistently positive.

Conclusion

The development of a community EPAU has improved services to allow care closer to home in an environment separate from maternity care. Our data shows that a community EPAU can deliver timely, good quality patient care, is safe, and a service valued by patients. Further research is indicated to evaluate the cost-effectiveness of community EPAUs and the long term safety and effectiveness of care.

Development of the "POP" scoring system for predicting obstetric and gynecological diseases in the emergency department: a retrospective cohort study

Background

Obstetric and gynecological (OBGY) diseases are among the most important differential diagnoses for young women with acute abdominal pain. However, there are few established clinical prediction rules for screening OBGY diseases in emergency departments (EDs). This study aimed to develop a prediction model for diagnosing OBGY diseases in the ED.

Methods

This single-center retrospective cohort study included female patients with acute abdominal pain who presented to our ED. We developed a logistic regression model for predicting OBGY diseases and assessed its diagnostic ability. This study included young female patients aged between 16 and 49 years who had abdominal pain and were examined at the ED between April 2017 and March 2018. Trauma patients and patients who were referred from other hospitals or from the OBGY department of our hospital were excluded.

Results

Out of 27,991 patients, 740 were included. Sixty-five patients were diagnosed with OBGY diseases (8.8%). The “POP” scoring system (past history of OBGY diseases + 1, no other symptoms + 1, and peritoneal irritation signs + 1) was developed. Cut-off values set between 0 and 1 points, sensitivity at 0.97, specificity at 0.39, and negative likelihood ratio (LR-) of 0.1 (95% CI: 0.02–0.31) were considered to rule-out, while cut-off values set between 2 and 3 points, sensitivity at 0.23 (95% CI 0.13–0.33), specificity at 0.99 (95% CI 0.98–1.00), and positive likelihood ratio (LR+) of 17.30 (95% CI: 7.88–37.99) were considered to rule-in.

Conclusions

Our “POP” scoring system may be useful for screening OBGY diseases in the ED. Further research is necessary to assess the predictive performance and external validity of different data sets.

Perception and knowledge of early pregnancy assessment units among perinatal practitioners in Europe

OBJECTIVE

To investigate perceptions of early pregnancy assessment units (EPAUs) among perinatal practitioners working in Belgium, France, and Switzerland.

METHODS

A prospective multinational survey was conducted between September 1, 2015, and May 21, 2016. Obstetricians, gynecologists, medical doctors, radiologists, and midwives were recruited during meetings, via e-mail invitations, or through the websites of regional obstetrics and gynecology scientific societies. The survey comprised 17 questions that assessed the participants' knowledge, interest, and management of early pregnancy.

RESULTS

Of the 871 individuals invited to participate in the survey, 306 (35.1%) responded. Most of the participants were gynecologists and/or obstetricians (225 [73.5%]). A total of 258 (84.3%) participants had no or limited knowledge about EPAUs. Furthermore, 211 (69.0%) participants reported incorrect management when they visualized a gestational sac without embryo and 265 (86.6%) misinterpreted changes in serum levels of chorionic gonadotropin during early pregnancy. In all, 201 (65.7%) participants were interested in collaboration with an EPAU; however, only 125 (40.8%) had sufficient time and resources available to support a patient's psychological distress after early pregnancy loss or salpingectomy.

CONCLUSION

Knowledge about early management of pregnancy was limited among the perinatal practitioners surveyed; however, the concept of EPAUs was welcomed by many.

Optimal Combination of Non-Invasive Tools for the Early Detection of Potentially Life-Threatening Emergencies in Gynecology

Objectives

Potentially life-threatening gynecological emergencies (G-PLEs) are acute pelvic conditions that may spontaneously evolve into a life-threatening situation, or those for which there is a risk of sequelae or death in the absence of prompt diagnosis and treatment. The objective of this study was to identify the best combination of non-invasive diagnostic tools to ensure an accurate diagnosis and timely response when faced with G-PLEs for patients arriving with acute pelvic pain at the Gynecological Emergency Department (ED).

Methods

The data on non-invasive diagnostic tools were sourced from the records of patients presenting at the ED of two hospitals in the Parisian suburbs (France) with acute pelvic pain between September 2006 and April 2008. The medical history of the patients was obtained through a standardized questionnaire completed for a prospective observational study, and missing information was completed with data sourced from the medical forms. Diagnostic tool categories were predefined as a collection of signs or symptoms. We analyzed the association of each sign/symptom with G-PLEs using Pearson’s Chi-Square or Fischer’s exact tests. Symptoms and signs associated with G-PLEs (p-value < 0.20) were subjected to logistic regression to evaluate the diagnostic value of each of the predefined diagnostic tools and in various combinations.

Results

The data of 365 patients with acute pelvic pain were analyzed, of whom 103 were confirmed to have a PLE. We analyzed five diagnostic tools by logistic regression: Triage Process, History-Taking, Physical Examination, Ultrasonography, and Biological Exams. The combination of History-Taking and Ultrasonography had a C-index of 0.83, the highest for a model combining two tools.

Conclusions

The use of a standardized self-assessment questionnaire for history-taking and focal ultrasound examination were found to be the most successful tool combination for the diagnosis of gynecological emergencies in a Gynecological ED. Additional tools, such as physical examination, do not add substantial diagnostic value.

Impact of accreditation training for residents on sonographic quality in gynecologic emergencies

OBJECTIVES

To assess the impact of an educational intervention based on an original accreditation training program on the quality of emergency sonography performed by obstetrics and gynecology (Ob/Gyn) residents.

METHODS

We conducted a prospective before-after study on residents who performed bedside standardized sonographic examinations as first-line investigations in patients seen at our gynecologic emergency department. In both periods, the residents followed a 1-hour class taught by a board-certified Ob/Gyn sonography expert (opinion leader) and received a written standardized imaging protocol. An accreditation training process was implemented for the new residents at the beginning of the second period: 5 complete sonographic examinations were required for each resident, and facilitated feedback from the opinion leader was performed using a dedicated sonographic quality score. During both periods, all consecutive sonograms were collected and stored. The primary outcome was the sonographic quality score. A mixed model for repeated measures was used to compare scores in both periods from 20 consecutive sonographic examinations performed by 5 residents who were different in each period.

RESULTS

The mixed model analysis showed an increase in quality scores in the post-accreditation training compared to the pre-accreditation training period (estimated coefficient ± SD, 4.13 ± 0.51; t = 8.16). The sonographic examination order also had a significant effect in both periods (estimated coefficient ± SD, 0.11 ± 0.03; t = 3.99).

CONCLUSIONS

An accreditation training process including facilitated feedback from a local opinion leader improved the quality of sonographic examinations performed by Ob/Gyn residents in women presenting to a gynecologic emergency department.

Use of ultrasound in emergency gynaecology

Ultrasound scan (USS) is an important tool for assessing and diagnosing early pregnancy and gynaecological emergencies. Providing an ultrasound scanning service at all hours would enable and ease prompt diagnosis and appropriate management. It would also help hospitals in reducing costs secondary to unnecessary admissions due to lack of ultrasound out of hours. We have conducted a retrospective observational study that looked into the out of hours admissions to a busy early pregnancy unit in a general district hospital, over a 3-month period. Our results highlight the important role and possible benefits of using ultrasound out of hours and prove it is a cost-effective approach. However, providing ultrasound scanning out of hours is affected by limitations of staff and resources at each unit. This could be avoided by following a multidisciplinary approach in acute services and providing more training for medical staff in ultrasound scanning.

Non-invasive tools for the diagnosis of potentially life-threatening gynaecological emergencies: a systematic review

OBJECTIVE

To identify non-invasive tools for diagnosis of the major potentially life-threatening gynaecological emergencies (G-PLEs) reported in previous studies, and to assess their diagnostic accuracy.

METHODS

MEDLINE; EMBASE; Cochrane Central Register of Controlled Trials (CENTRAL; The Cochrane Library) were searched to identify all eligible studies published in English or French between January 1990 and December 2012. Studies were considered eligible if they were primary diagnostic studies of any designs, with a gold standard and with sufficient information for construction of a 2 × 2 contingency table, concerning at least one of the following G-PLEs: complicated ectopic pregnancy, complicated pelvic inflammatory disease, adnexal torsion and haemoperitoneum of any gynaecological origin. Extraction of data and assessment of study quality were conducted by two independent reviewers. We set the thresholds for the diagnostic value of signs retrieved at Sensibility ≥ 95% and LR-≤ 0.25, or Specificity ≥ 90% and LR+ ≥ 4.

RESULTS

We identified 8288 reports of diagnostic studies for the selected G-PLEs, 45 of which met the inclusion criteria. The methodological quality of the included studies was generally low. The most common diagnostic tools evaluated were transvaginal ultrasound (20/45), followed by medical history (18/45), clinical examination (15/45) and laboratory tests (14/45). Standardised questioning about symptoms, systolic blood pressure<110 mmHg, shock index>0.85, identification of a mass by abdominal palpation or vaginal examination, haemoglobin concentration <10 g/dl and six ultrasound and Doppler signs presented high performances for the diagnosis of G-PLEs. Transvaginal ultrasound was the diagnostic tool with the best individual performance for the diagnosis of all G-PLEs.

CONCLUSION

This systematic review suggests that blood pressure measurement, haemoglobin tests and transvaginal ultrasound are cornerstone examinations for the diagnosis of G-PLEs that should be available in all gynaecological emergency care services. Standardised questioning about symptoms could be used for triage of patients.

Triage using a self-assessment questionnaire to detect potentially life-threatening emergencies in gynecology

Objective

Acute pelvic pain is a common reason for emergency room visits that can indicate a potentially life-threatening emergency (PLTE). Our objective here was to develop a triage process for PLTE based on a self-assessment questionnaire for gynecologic emergencies (SAQ-GE) in patients experiencing acute pelvic pain.

Methods

In this multicenter prospective observational study, all gynecological emergency room patients seen for acute pelvic pain between September 2006 and April 2008 completed the SAQ-GE after receiving appropriate analgesics. Diagnostic procedures were ordered without knowledge of questionnaire replies. Laparoscopy was the reference standard for diagnosing PLTE; other diagnoses were based on algorithms. In two-thirds of the population, SAQ-GE items significantly associated with PLTEs (P < 0.05) by univariate analysis were used to develop a decision tree by recursive partitioning; the remaining third served for validation.

Results

Of 344 derivation-set patients and 172 validation-set patients, 96 and 49 had PLTEs, respectively. Items significantly associated with PLTEs were vomiting, sudden onset of pain, and pain to palpation. Sensitivity of the decision tree based on these three features was 87.5% (95% confidence interval (95% CI), 81%-94%) in the derivation set and 83.7% in the validation set. Derivation of the decision tree provided probabilities of PLTE of 13% (95% CI, 6%-19%) in the low-risk group, 27% (95% CI, 20%-33%) in the intermediate-risk group and 62% (95% CI, 48%-76%) in the high-risk group, ruling out PLTE with a specificity of 92.3%; (95% CI, 89%-96%). In the validation dataset, PLTE probabilities were 16.3% in the low-risk group, 30.6% in the intermediate-risk group, and 44% in the high-risk group, ruling out the diagnosis of PLTE with a specificity of 88.6%.

Conclusion

A simple triage model based on a standardized questionnaire may assist in the early identification of patients with PLTEs among patients seen in the gynecology emergency room for acute pelvic pain.

[Evolution of waiting time and length of stay between 2005 and 2012 in an obstetric and gynaecologic emergency unit in a French teaching hospital]

OBJECTIVES

To compare and analyze waiting time and length of stay between 2005 and 2012 in the obstetric and gynaecologic emergency unit of Nantes teaching hospital, new unit opened in 2004.

METHODS

Descriptive study from the registers over 2months' periods in 2005 and 2012.

RESULTS

Despite an increase of the daily average number of visits from 28 to 39 (P<0.0001), the waiting time increased in obstetrics from 15minutes to 18 in 2012, P<0.03. In gynaecology, waiting time decreased in 2012 on daytime weekdays (37minutes versus 44) and increased on weekend (41minutes versus 28) and at night (37minutes versus 23) P<0.01. The length of stay was similar in obstetrics (108minutes versus 104) but reduced on daytime weekdays (124minutes in 2005, 109 in 2012, P<0.05). In gynaecology duration was similar (108minutes versus 105), but decreased on daytime weekdays (110minutes in 2005, 101 in 2012) and increased on overnight weekend (94minutes in 2005, 121 in 2012) (P<0.05).

CONCLUSION

Our organization enabled to improve some lengths of time despite an increased activity. Those lengths of time should be monitored as they reflect our organizations and are indicators of efficiency.

Routine ultrasound examination by OB/GYN residents increase the accuracy of diagnosis for emergency surgery in gynecology

Introduction

Diagnostic accuracy of first-line sonographic evaluation by obstetrics/gynecology residents in determining the need for emergency surgery in women with acute pelvic pain is unknown. Aim of this study was to evaluate the diagnostic accuracy of routine ultrasound evaluation by obstetrics/gynecology residents, available 24 hours a day, in patients with acute pelvic pain.

Methods

A cross-sectional retrospective study included consecutive patients who underwent emergency laparoscopy for acute pelvic pain at a teaching hospital gynecologic emergency unit, between January 1, 2004, and December 31, 2006. The laparoscopic diagnosis was the reference standard. Gynecologic and nongynecologic conditions requiring immediate surgery to avoid severe morbidity or death were defined as surgical emergencies. In all patients, obstetrics/gynecology residents routinely performed clinical examination and standardized ultrasonography was routinely recorded. Sonograms were re-interpreted for the study, blinded to physical examination and laparoscopic findings, according to evidence-based predetermined criteria. Sensitivity, specificity, and likelihood ratios were computed for clinical data alone, sonographic data alone, and the combination of both.

Results

Emergency laparoscopy was performed in 234 patients, diagnosing 139 (59%) surgical emergencies. Clinical and sonographic examinations performed by the residents each independently predicted a need for emergency surgery. Combining both examinations was superior over each examination alone and had an acceptable false-negative rate of 1%.

Conclusions

First-line combined clinical and sonographic examination by obstetrics/gynecology residents is effective in ruling out surgical emergencies in patients with acute pelvic pain.

Cost-effectiveness of ultrasound use by on-call registrars in an acute gynaecology setting

Ultrasound, and in particular transvaginal sonography (TVS), plays an important role in the management of women with acute gynaecology conditions. This study compared the cost-effectiveness of two models of out-of-hours care for women in an acute gynaecology setting. In the ultrasound-based model, the on-call registrar with ultrasound experience managed such patients after performing pelvic ultrasound as a part of the initial assessment. On the other hand, in the traditional model of care the on-call registrar managed the patients without the use of ultrasound. The conclusion is that the use of ultrasound by the on-call registrars has significant cost implications through reduced hospital admissions. It leads to improved outcomes of such patients through timely diagnosis and treatment.

The accuracy of the preoperative diagnosis in women undergoing emergent gynecological laparoscopy for acute abdominal pain

OBJECTIVES

To analyze the accuracy of the working diagnosis in emergent laparoscopies and identify variables associated with an accurate or faulty preoperative diagnosis.

METHODS

A retrospective cohort study including 217 consecutive women who underwent emergent laparoscopy for acute abdominal pain in 2000-2007. Each case was designated a preoperative-postoperative diagnostic match or mismatch by file review. The agreement between the clinical and preoperative ultrasound findings was analyzed according to the circumstances of imaging tests (Doppler-ultrasound examination performed by a specialist or ultrasound performed by the on-call physician without Doppler examination).

RESULTS

On multivariate logistic stepwise regression analysis, the significant independent variables for prediction of preoperative-postoperative diagnostic match (n = 63, 29%) were pregnant state, preoperative clinical-ultrasound match, and duration of symptoms. The circumstances of imaging tests were not a significant predictor for accurate preoperative diagnosis.

CONCLUSIONS

In this retrospective analysis, Doppler-ultrasound examination performed by a specialist was not associated with higher accuracy of the preoperative diagnosis in women undergoing emergent laparoscopy for acute abdominal pain. These data should be further validated in future prospective cohorts. Doppler-ultrasound examination performed by a specialist does not add to the accuracy of the preoperative diagnosis in women undergoing emergent gynecological laparoscopy for acute abdominal pain.
