AI Technical Summary
In emergency obstetrics and gynecology departments, the lack of effective triage standards in current technology leads to untimely identification of pregnant women's conditions, affecting treatment and rescue, and the low triage accuracy rate makes it impossible to effectively reduce maternal mortality and complication rates.
A triage standard for emergency obstetrics and gynecology departments was developed, including single objective indicators, single subjective indicators, and critical signs/condition indicators. The standard was then used to classify patients into risk levels, critical illness levels, emergency levels, and non-emergency levels through the hospital triage system. The standard was further validated through expert consultation and clinical practice to improve triage accuracy.
It improved the triage accuracy of triage nurses from 90.25% to 96.98%, and shortened the green channel opening time for critically ill patients from 16.89±9.701 minutes to 6.55±2.012 minutes, significantly improving triage efficiency and treatment time.

Abstract
Description
Technical Field
[0001] This invention relates to the field of emergency triage technology, and in particular to a method for constructing emergency obstetrics and gynecology triage standards. Background Technology
[0002] Maternal and infant health is an important indicator of a society's overall healthcare level and quality of life. International health organizations primarily focus on three core metrics when assessing the health status of residents in different countries: life expectancy, newborn survival rate, and maternal safety index.
[0003] In maternal and child health hospitals, the emergency obstetrics and gynecology department is a relatively independent department with a high risk factor, accounting for approximately 50% of all patients. Women of childbearing age have strong physiological and metabolic functions, leading to rapid onset and acute illness. The conditions of pregnant women seeking treatment can change rapidly, threatening the lives of both mother and baby if not treated promptly, and causing conflicts between nurses and patients. From 2008 to 2020, medical disputes in obstetrics and gynecology departments of tertiary-level Class A hospitals in my country accounted for 10.2%, ranking third among medical disputes. Among all medical disputes in maternal and child health hospitals in my country, obstetrics and gynecology-related disputes account for 64.3%.
[0004] With the adjustment of my country's birth control regulations and the gradual relaxation of the two-child and three-child policies, the fertility rate of older women has increased significantly. The US Vital Statistics report shows that the fertility rate of women aged 35-39 increased by 5% in 2021. In my country, the proportion of abnormal pregnancies, such as advanced maternal age, women with scarred uteruses, and women who have had multiple pregnancies through assisted reproductive technology, is increasing. Some multiparous women have lower adherence to prenatal checkups, medical treatment, and doctor's orders, and their physical condition is generally worse than that of first-time mothers. Therefore, the incidence of maternal complications, the complexity of conditions, and precipitous labor in the pre-hospital and emergency departments has increased significantly. According to statistics from my country's National Health and Family Planning Commission, six months after the full implementation of the two-child policy in 2016, the maternal mortality rate increased by 30.6% compared to the same period in 2015. The total number of maternal deaths in my country each year is 3.5 times that of developed countries.
[0005] Although a pregnant woman's condition can change rapidly, early identification of acute and critical signs and effective intervention can prevent potential risks and reduce maternal mortality. In developed countries like the UK and the US, 40%–60% of maternal deaths can be prevented through timely intervention. In clinical practice, the process from the onset of illness to death involves identification and diagnosis. Failure to promptly identify and diagnose changes in a pregnant woman's condition will delay treatment and resuscitation. Therefore, the efficient, rapid, and accurate identification of potential risks in acutely ill pregnant women by triage nurses, and the immediate implementation of appropriate interventions, are crucial to ensuring the quality of life for pregnant women.
[0006] Emergency triage prioritizes patients in the emergency department, ensuring that those requiring immediate intervention receive medical care. Triage personnel assess patients using triage forms and their individual circumstances, then triage them to the appropriate areas, with a particular focus on identifying critically ill patients for priority diagnosis and treatment. Epidemiological data shows that approximately 25% of women of childbearing age in my country have high-risk pregnancies, and about 15% of these pregnancies may result in life-threatening complications that can lead to serious long-term health consequences. Given the special and urgent nature of these patients, establishing a standardized and scientific triage assessment system in the emergency obstetrics and gynecology department is crucial. This not only helps triage nurses quickly identify critically ill patients but also ensures timely initiation of appropriate nursing interventions, thereby effectively reducing the incidence of adverse pregnancy outcomes.
[0007] In response, the inventor of this patent, combining clinical experience, reflecting on problems encountered in clinical work, reviewing a large amount of scientific research data and literature, and conducting a novelty search, gradually conceived, designed and demonstrated the feasibility of this application in order to solve the relevant technical problems.

[0028] The following describes in detail, with reference to the accompanying drawings, the method for constructing the emergency obstetrics and gynecology triage standard according to an embodiment of the present invention.
[0029] Reference Figures 1 to 12 As shown, the method for constructing emergency obstetrics and gynecology triage standards according to an embodiment of the present invention includes the following steps: S1. Determine the pre-examination and triage criteria, which include a single objective indicator, a single subjective indicator, and critical signs / condition indicators; The individual objective indicators include: consciousness, signs of fetal distress, amniotic fluid properties, premature rupture of membranes, respiration, blood pressure, heart rate, shock index, blood oxygen saturation, and results of tests for critical values. Furthermore, the individual subjective indicators include: neurological complaints, amount of vaginal bleeding, frequency of regular uterine contractions, amount of vaginal fluid discharge, fetal movement, pain index, and chest discomfort; The critical signs / conditions mentioned include: cardiac and respiratory arrest, airway obstruction or suffocation, umbilical cord prolapse, fetal limb prolapse outside the cervix, severe abdominal pain in pregnant women, significant discomfort or uterine contractions in pregnant women after external impact to the abdomen or waist, vaginal bleeding, abdominal pain, painless vaginal bleeding in pregnant women with prenatal diagnosis of vasa previa, regular uterine contractions in placenta accreta, ovarian cyst torsion, ectopic pregnancy and corpus luteum rupture, persistent vomiting in pregnant women, gestational age ≥20 weeks and amniotic fluid index ≤5.0 on ultrasound, gestational age ≥20 weeks and diarrhea unrelated to diet, menstrual irregularities and vaginitis; It should be noted that the aforementioned single objective indicators were derived through in-depth literature analysis, review of the textbook "Critical Care Nursing", and clinical practice summary. Our research team optimized the single objective indicator system, mainly by adding two assessment elements, shock index and amniotic fluid properties, to the existing emergency obstetrics and gynecology triage standards.
[0030] The main considerations for selecting these two assessment elements are as follows: First, this indicator is of great significance in hemodynamic monitoring, as reflected in many clinical guidelines; second, its clinical application value has been confirmed through repeated demonstrations and practical verification by the research team members; third, this indicator is easy to calculate and provides clear results, which can meet the actual work needs of frontline medical staff and facilitate rapid assessment of patient status.
[0031] Furthermore, the inclusion of amniotic fluid properties in the assessment system is primarily based on the following criteria: First, changes in amniotic fluid properties can directly reflect the fetal intrauterine status and the risk of maternal pregnancy complications; second, by observing the characteristics of amniotic fluid such as color, turbidity, and odor, potential complications such as fetal distress and intrauterine infection can be detected in a timely manner; third, this indicator is convenient to observe, making it a truly important single objective indicator for clinical risk assessment in emergency obstetrics and gynecology.
[0032] Furthermore, regarding the aforementioned individual subjective indicators, in order to systematically study the textbook "Obstetrics and Gynecology" and analyze the data of emergency obstetrics and gynecology patients, our research team expanded the individual subjective indicators. Based on summarizing clinical adverse event cases and the characteristics of patients' chief complaints, we added two individual subjective indicators: vaginal discharge volume and chest discomfort. It should be noted that the critical signs / conditions indicators mentioned above were added during the refinement process. This was achieved through in-depth study of the professional textbook "Obstetrics and Gynecology," systematic review of emergency room records, and analysis of complaint cases. The newly added critical signs / conditions indicators are as follows: ovarian cyst torsion, corpus luteum rupture, persistent vomiting in pregnant women, amniotic fluid index ≤5.0 on ultrasound at ≥20 weeks of gestation, diarrhea unrelated to diet at ≥20 weeks of gestation, menstrual irregularities, and vaginitis.
[0033] S2. The pre-examination and triage standards are classified into levels through the hospital triage system. The classification standards include the critical level (Level I) that requires immediate pre-examination and triage, the critical level (Level II) that requires pre-examination and triage within 10 minutes, the emergency level (Level III) that requires pre-examination and triage within 30 minutes, and the non-emergency level (Level IV) that requires pre-examination and triage within 60-120 minutes. It should be noted here that: For patients with unstable vital signs, their condition is at risk of rapid deterioration, requiring immediate treatment. The emergency department must allocate medical resources and equipment to provide emergency care. In this study, patients classified as Level I (critical condition) were given an immediate response timeframe by the triage nurses.
[0034] For patients with severe conditions, their symptoms may rapidly deteriorate to a life-threatening level within a short period, requiring priority medical treatment and appropriate healthcare measures. In this study, patients classified as acute and severe (Level II) had a response time of within 10 minutes for triage nurses.
[0035] For emergency patients who do not pose an immediate risk of life-threatening danger or significant functional impairment, the medical team can appropriately arrange their medical process within a specific time frame. In this study, patients classified as emergency level (Level III) had a response time limit of 30 minutes for triage nurses.
[0036] Patients whose current condition is stable, who do not exhibit acute symptoms, and who have no obvious discomfort or only mild symptoms are classified as non-emergency level (Level IV) in this study. The response time for triage nurses is 60-120 minutes.
[0037] S3. Conduct a preliminary trial of the triage criteria that have been graded to assess their reliability; Steps S1 and S2 are analyses and theoretical summaries based on various data. Therefore, when applying them clinically, they need to be tested in practice, i.e., step S3, to evaluate the reliability of the triage criteria described in this application.
[0038] When assessing the reliability of the pre-screening and triage criteria described in this application, step S4 can be performed, namely: S4. Verify the pre-testing and triage standards that have been tested in practice, that is, conduct clinical practice to verify their ultimate scientific validity and feasibility.
[0039] Based on the above, it is clear that in its specific implementation, this application mainly discloses a method for constructing pre-examination and triage standards for emergency obstetrics and gynecology departments.
[0040] Specifically, when applying this application, the pre-examination and triage standards described herein have been pre-tested and their reliability has been fully determined. In clinical application, their scientific validity and feasibility have also been verified. As a result, the construction of this application can significantly improve the triage accuracy of emergency obstetrics and gynecology triage nurses in clinical application, and can effectively shorten the opening time of the green channel for critically ill patients in emergency obstetrics and gynecology, which is of great significance for improving the quality of pre-examination and triage in emergency obstetrics and gynecology.
[0041] Furthermore, in a specific implementation according to an embodiment of the present invention, step S1 specifically includes: S11. Determine the inclusion and exclusion criteria for the literature, systematically search relevant databases of obstetrics and gynecology triage standards at home and abroad, and screen literature that meets the requirements; Specifically, according to one embodiment of the present invention, in step S11, The inclusion criteria for the literature were as follows: the study type was original research, clinical research, observational research, and guidelines related to emergency obstetrics and gynecology triage; the study subjects were obstetrics and gynecology emergency patients, including pregnant women and gynecological emergency patients; the interventions were measures related to triage, including triage standards and emergency procedures; and the outcome indicators were triage accuracy, waiting time, patient satisfaction, and clinical outcomes. The exclusion criteria for literature are: duplicate publications, literature of low research quality, literature with incomplete data, and literature unrelated to the research topic.
[0042] Through step S11, a total of 1851 articles were retrieved (1248 from CNKI, 104 from Wanfang Medical Database, 4 from China Biomedical Literature Database, 308 from PubMed, and 187 from Webofscience). After filtering the articles by removing duplicates and reviewing their titles and abstracts, 12 articles that met the requirements were included.
[0043] The detailed search flowchart is attached to this application specification. Figure 1 As shown; the selected literature is listed in the appendix to this application specification. Figure 2 .
[0044] S12. Conduct methodological quality evaluation on the selected literature that meets the requirements, assess the rationality and scientificity of the research design, extract key research data and results through the design of standardized data extraction tables, organize and statistically analyze the data, and form a summary of evidence. The resulting summary diagram of evidence is shown in the appendix to this application. Figure 3 As shown.
[0045] S13. Establish an expert inquiry group and use the Delphi expert inquiry method to conduct an inquiry questionnaire survey on the collected evidence through experts. In step S13, the interpretation of the Delphi expert consultation method can be understood as follows: the size, academic influence, and field distribution of the expert consultation team are the core elements constituting the Delphi method, and are of great significance in reducing research bias. Based on systematic literature review, evidence-based practice, and team discussions, a preliminary triage plan for emergency obstetrics and gynecology departments is formulated.
[0046] The specific procedures are as follows: Expert suggestions are collected through anonymous inquiries; the feedback is analyzed and integrated to create a revised questionnaire, and expert opinions are solicited again. This process is repeated until a consensus is reached. Throughout the consultation process, the principle of expert confidentiality is strictly adhered to, avoiding mutual interference and ensuring that each expert thinks independently and provides objective and credible professional judgment.
[0047] Furthermore, the actual operation process of step S13 is as follows: S131. Establish an expert consultation group; Following the sample size setting principles for expert opinion consultation and in accordance with the research objectives, this study selected 16 experts from 8 district-level maternal and child health hospitals (maternal and child specialty hospitals) in Shenzhen. Inclusion criteria: ① Maternal and child specialty hospitals; ② Clinical nursing experts in emergency obstetrics and gynecology triage or obstetrics and gynecology wards; ③ Holding a senior nurse title or above; ④ Holding a bachelor's degree or above; ⑤ Having 10 years or more of work experience in their professional field; ⑥ Willing to participate in this research project, able to actively provide comprehensive and guiding opinions and suggestions, and able to complete two rounds of consultations. Exclusion criteria: ① Unwilling to participate in this research project; ② Withdrawing midway.
[0048] S132. Compile expert inquiry questionnaires; Based on the initial draft of the pre-examination and triage standards for the emergency obstetrics and gynecology departments of maternal and child health hospitals, the research team developed an expert inquiry form, which includes three parts: (1) Explain the application goals and practical value of the inquiry form in the research, as well as the guiding significance of expert suggestions for the research.
[0049] (2) Instructions for filling out the form, basic information collection form for experts, and the basis for experts' judgment on the content of the inquiry and their level of familiarity with it. The basis for experts' judgment on the content of the inquiry includes practical experience, theoretical analysis, references, and intuitive selection; the familiarity with the content of the inquiry is divided into three aspects: familiarity with the content of the inquiry, familiarity with the requirements of emergency obstetrics and gynecology triage, and familiarity with the process of emergency obstetrics and gynecology triage. The level of familiarity is as follows: very familiar, familiar, average, not very familiar, and unfamiliar.
[0050] (3) The content of the consultation letter for the pre-examination and triage standards of the emergency obstetrics and gynecology department of the maternal and child specialist hospital: expert consultation form for single objective indicators, including expert consultation on the types, importance and classification of single objective indicators; expert consultation form for single subjective indicators, including expert consultation on the types, importance and classification of single subjective indicators; expert consultation form for critical signs / conditions and other indicators, including expert consultation on the types, importance and classification of critical signs / conditions and other indicators.
[0051] Both rounds of expert consultations were conducted via email. The results of both rounds of consultations were then compiled and analyzed. Items were then added to, deleted from, or modified. The second round of expert opinions reached a consensus, and the consultation process concluded.
[0052] S14. Analyze and summarize the results of the questionnaire survey to derive the final pre-examination and triage criteria.

[0064] S34. Select one qualified triage nurse to play the role of a patient and another qualified triage nurse to play the role of a caregiver, and complete the scenario simulation of the 20 classic cases one by one. S35. Select ten more qualified triage nurses to participate in the pre-practice operation, and triage them respectively in the scenario simulations presented in the 20 classic cases. S36. Statistically analyze the triage results of the ten qualified triage nurses in the scenario drills presented in the 20 classic cases, and compare them with the triage level setting standards. Results of 10 pre-trial triage nurses triaging 20 classic cases: 28 cases were accurately triaged to the endangered level (Level I); 9 cases were incorrectly classified as critical illness level (Level II) to the endangered level (Level I); and 3 cases were incorrectly classified as emergency level (Level III) to the endangered level (Level I).
[0065] The number of cases correctly triaged to the acute and severe illness level (Level II) was 26; 8 cases were incorrectly classified as critically ill (Level I) due to the acute and severe illness level (Level II); and 6 cases were incorrectly classified as acute (Level III) due to the acute and severe illness level (Level II).
[0066] The number of cases correctly triaged to the acute level (Level III) was 64; 1 case was incorrectly classified as critical level (Level I) to the acute level (Level III); 13 cases were incorrectly classified as acute and severe level (Level II) to the acute level (Level III); and 2 cases were incorrectly classified as non-acute level (Level IV) to the acute level (Level III).
[0067] The accurate number of cases triaged under the non-emergency level (Level IV) was 40.
[0068] Specific triage results are as shown in the appendix to this application. Figure 5 As shown.
[0069] S37. The comparison results show high consistency, thus confirming the reliability of the pre-examination and triage criteria.
[0070] (1) The consistency of the pre-examination and triage of 20 scenario simulation cases among 10 nurses was compared. The results showed that it was statistically significant (P<0.001). The Kendall coefficient of harmony was 0.727, indicating that the scoring criteria among the 10 nurses were relatively consistent.
[0071] The specific Kendall's coefficient of coordination statistics are shown in the appendix to this application. Figure 6 As shown.
[0072] (2) The Cronbach's alpha coefficient between the nurses' pre-examination triage results and the standard triage results was 0.713, the unweighted Kappa value was 0.711 (95% CI 0.634-0.788), the linearly weighted Kappa value was 0.795 (95% CI 0.735-0.855), and the quadratic weighted Kappa value was 0.870 (95% CI 0.822-0.917), indicating that the pre-examination triage results of the 10 nurses were relatively consistent with the standard triage results.
[0073] The specific Cronbach's alpha reliability analysis statistics are shown in the appendix to this application. Figure 7 As shown in the attached table; a statistical table showing the consistency between nurses' pre-screening and triage results and standard triage results, as per this application specification. Figure 8 As shown.
[0074] Therefore, this preliminary practice, through statistical analysis of 10 emergency obstetrics and gynecology triage nurses, assessed individual objective indicators, individual subjective indicators, critical signs / conditions indicators, and other indicators of 20 classic cases to complete the triage process. By measuring the consistency among triage nurses and the consistency between the triage results and the standard triage results, the analysis concludes that the triage criteria described in this application have high reliability.
[0075] Furthermore, in a specific implementation according to an embodiment of the present invention, step S4 specifically includes: S41. Select patient samples and set up a control group and an experimental group. The patients in the control group and the experimental group were all female, of similar age, and at the same triage level. Each group had 728 patients, for a total of 1456 patients, which was a very sufficient sample size.
[0076] S42. Patients in the control group were triaged and screened according to the existing emergency obstetrics and gynecology triage guidelines; patients in the experimental group were triaged and screened according to the aforementioned triage standards. Specifically, the control group consisted of emergency obstetrics and gynecology triage nurses who triaged emergency obstetrics and gynecology patients from January 1 to March 31, 2024, using the department's existing emergency obstetrics and gynecology triage standard guidelines. The experimental group consisted of emergency obstetrics and gynecology triage nurses who triaged emergency obstetrics and gynecology patients from May 15 to August 15, 2024, using the triage standards described in this application.
[0077] Among them, the existing emergency obstetrics and gynecology triage standard guidelines are attached to this application. Figure 9 As shown; S43. Statistical methods were used to analyze the triage accuracy rates of patients in the control group and patients in the experimental group.
[0078] The basic information statistics of patients in the control group and the experimental group are attached to this application specification. Figure 10 As shown.
[0079] S44. Statistical results show that the triage accuracy rate of the control group was 90.25%, while that of the experimental group was 96.98%.
[0080] A detailed comparison table of triage result accuracy is attached to this application. Figure 11 As shown.
[0081] Furthermore, before the implementation of the pre-examination and triage standards for the emergency obstetrics and gynecology department of the maternal and child health hospital, the opening time (in minutes) for the green channel for critically ill patients was 16.89±9.701 minutes; after the implementation of the standards, the opening time (in minutes) for the green channel for critically ill patients was 6.55±2.012 minutes. The reduction in the opening time (in minutes) of the green channel for critically ill patients after the implementation of the pre-examination and triage standards for the emergency obstetrics and gynecology department of the maternal and child health hospital compared to before the implementation of the standards was statistically significant (P<0.05). The comparison chart showing the time limit for the green channel for critically ill patients in the control group and the experimental group is attached to this application. Figure 12 As shown.
[0082] Therefore, it is evident that by adopting the triage standards described in this application, the triage accuracy rate of triage nurses can be increased from 90.25% to 96.98% (P < 0.001), and the opening time of the green channel for critically ill patients can be shortened from 16.89 ± 9.701 minutes to 6.55 ± 2.012 minutes (P < 0.001). This demonstrates that the application of this application has a significant effect on improving triage efficiency and shortening the treatment time for critically ill patients.
[0083] Other embodiments, etc., will not be described here.
[0084] In summary, the method for constructing emergency obstetrics and gynecology triage standards provided in this application, in practical implementation, firstly, integrates a four-dimensional evaluation system comprising single objective indicators, single subjective indicators, critical signs / condition indicators, and other indicators, providing triage nurses with a more comprehensive and accurate decision-making basis, effectively improving triage accuracy.
