Its incidence is increasing globally, and early diagnosis and timely intervention are crucial for reducing mortality and preserving fertility. This study aims to investigate the role of a novel emergency model based on the trauma green channel and an emergency virtual ward in improving the treatment efficiency for patients with ectopic pregnancy. Methods A retrospective study was conducted on 63 ectopic pregnancy patients who underwent emergency surgery in our hospital between January 2023 and April 2025. They were divided into a traditional model group (31 cases) and a trauma care model group (32 cases). General clinical data and eight emergency quality control indicators were collected and compared, including patient admission time, time to establish effective circulatory access, time to perform color Doppler ultrasound, time to obtain urine pregnancy test results, time to obtain serum β-hCG results, time to definitive diagnosis, time to enter the operating room, and satisfaction score with emergency care. Results No significant differences were found between the two groups in terms of age, vital signs, or length of hospital stay (P > 0.05). The trauma care model group had significantly lower total medical costs (P = 0.002) and a higher rate of fallopian tube preservation (43.8% vs. 19.4%, P = 0.034) compared to the traditional model group. Furthermore, the trauma care model group demonstrated significantly better results in all eight emergency quality control indicators (P < 0.05), and patient and family satisfaction with the emergency process was also significantly higher (P = 0.013). Conclusion The novel trauma emergency model for ectopic pregnancy, based on the trauma green channel and the emergency virtual ward, significantly optimized the emergency process, shortened key time points, reduced medical costs, and helped improve the rate of fertility preservation and patient satisfaction with emergency care. It demonstrates good value for clinical application and promotion. Ectopic Pregnancy Trauma Care Model Green Channel Virtual Ward Emergency Process Multidisciplinary Team (MDT) Figures Figure 1 Figure 2 Introduction Ectopic pregnancy refers to the implantation of a fertilized egg outside the uterine cavity, with tubal pregnancy being the most common type, accounting for approximately 95% of cases[1]. Studies have shown that its occurrence is closely related to factors such as pelvic inflammatory disease, history of ectopic pregnancy, and the use of assisted reproductive technologies[2]. In recent years, with the trend of delayed childbearing and rising rates of pelvic infections, the global incidence of ectopic pregnancy is about 1%-2%, and the incidence in China also reaches 1.5%-2.0%. The incidence has increased 4–6 fold over the past 30 years, making it one of the leading causes of maternal death in the first trimester, accounting for 2.7% of pregnancy-related deaths[3][4]. Once ruptured, ectopic pregnancy can lead to intra-abdominal hemorrhage and hemorrhagic shock, severely threatening the patient's life[5]. Currently, the diagnosis of ectopic pregnancy primarily relies on transvaginal ultrasonography and dynamic monitoring of serum beta-human chorionic gonadotropin (β-hCG) levels[6]. Treatment options include medical management, surgical intervention (typically laparoscopy), and expectant management. The choice depends on the patient's hemodynamic status, β-hCG levels, size of the gestational mass, and fertility desires[7]. Regardless of the approach, the treatment principles revolve around three key goals: "saving lives, removing the ectopic pregnancy, and preserving fertility"[5]. Therefore, establishing an efficient and standardized in-hospital emergency process for early diagnosis and rapid intervention is crucial for improving prognosis and preserving reproductive potential[8][9]. Although mature "green channel" models for trauma, chest pain, and stroke have been established domestically and internationally, significantly improving treatment efficiency[10][11], the exploration of structured emergency systems specifically for ectopic pregnancy, a unique obstetric and gynecological emergency, remains insufficient. Traditional emergency models often suffer from delays due to imprecise triage, poor coordination between departments, and long waiting times for examinations[12]. Inspired by the multidisciplinary team (MDT) concept and process optimization principles of trauma centers[13][14], and leveraging the advantages of the emerging "virtual ward" in integrating medical resources[15], our hospital attempted to integrate the trauma green channel with the emergency virtual ward to create a dedicated emergency model for ectopic pregnancy. This study aims to evaluate the effectiveness of this novel model in improving the efficiency of the emergency process for ectopic pregnancy patients by comparing it with the traditional model. 1. Research Objects and Methods 1.1 Research Objects A retrospective study was conducted on patients diagnosed with ectopic pregnancy who were admitted through the Emergency Surgery department of our hospital and underwent surgical treatment between January 2023 and April 2025. Based on the treatment mode, they were divided into a traditional care model group (31 cases) and a trauma care model group (32 cases). Inclusion criteria:(1) Surgically confirmed ectopic pregnancy; (2) Admission through the Emergency Surgery department. Exclusion criteria:(1) Patients seen in the outpatient department or receiving non-surgical treatment; (2) Patients with cesarean scar pregnancy or cornual pregnancy; (3) Patients with incomplete clinical data. The specific screening process is shown in Fig. 1 . 1.2 Research Methods 1.2.1 Human Resource Configuration Traditional Model: No fixed team. Initial diagnosis was made by rotating doctors in the emergency department. After diagnosis, patients transferred to the Obstetrics and Gynecology department on their own or accompanied by one nurse. The trauma center used a one-doctor, multiple-nurses model, but nurse roles were unclear, and team collaboration training was lacking. Novel Model: An ectopic pregnancy MDT team was established, consisting of emergency surgeons, obstetrician-gynecologists, laboratory staff, and ultrasonographers. A fixed team model of "two doctors and two nurses" was adopted (one emergency surgeon, one obstetrician-gynecologist, one trauma nurse, one intravenous access nurse), with clearly defined responsibilities. In addition to monthly routine training and assessment, regular team simulation drills and specialized training for critically ill patient transport were conducted. 1.2.2 Treatment Process Traditional Model: (1) Initial Assessment and Management: After the patient arrives at the hospital, triage staff inquire about the patient's general condition to preliminarily confirm the possibility of ectopic pregnancy and notify the emergency surgeon. (2) Subsequent Examinations: The doctor on duty conducts routine tests and examinations to confirm the diagnosis of ectopic pregnancy, with priority given to critically ill patients. However, this expedited service is limited to within the emergency department. (3) Ectopic Pregnancy Alert Activation: After confirmation, the obstetrics and gynecology department is contacted for admission. Emergency medical staff assist with the transfer to the obstetrics and gynecology ward throughout the process. (4) Subsequent Treatment: After entering the ward, subsequent treatment is led by the obstetrics and gynecology doctor on duty. Novel Model: (1) Ectopic Pregnancy Alert Activation: After the patient arrives at the hospital, well-trained triage staff inquire about the patient's general condition to preliminarily confirm the possibility of ectopic pregnancy and notify the emergency surgeon, thereby immediately activating the ectopic pregnancy alert. (2) Initial Assessment and Management: The emergency surgeon assesses the patient's general condition. The patient is moved to the resuscitation room for vital signs monitoring. (3) Subsequent Examinations: Rapid tests and examinations are performed via the green channel. (4) Subsequent Treatment: The patient is admitted to the emergency virtual ward. An obstetrics and gynecology doctor arrives on site within 10 minutes to assess the patient for subsequent treatment. A hospital-wide ectopic pregnancy green channel service system is established to ensure priority treatment for ectopic pregnancy patients across all relevant departments. In cases requiring urgent blood transfusion, the emergency surgeon or nurse can promptly notify the blood bank by phone to ensure timely transfusion. Patients with surgical indications receive priority for surgery. The obstetrics and gynecology doctor completes preoperative preparation in the resuscitation room via the virtual ward system, and the patient is transported directly from the emergency resuscitation room to the operating room within 30 minutes of admission to shorten surgical wait times. Furthermore, if patients face difficulties with medical payments, the principle of "treat first, pay later" applies to avoid delays in treating critically ill patients. Patients assessed as suitable for conservative treatment are transferred from the virtual ward to the obstetrics and gynecology ward for subsequent management. 1.2.3 Emergency Protocol Traditional Model Triage → Reception by emergency surgeon → Ordering tests → Patient completes tests independently → Contact Obstetrics & Gynecology after confirmation → Transfer to ward → Treatment arranged by OB/GYN doctor. Novel Model : (A) Admission 0 minutes: Experienced triage staff activate the alarm and initiate the MDT upon initial suspicion of ectopic pregnancy. (B) Admission 5 minutes: Patient enters the resuscitation room. Emergency bedside ultrasound, urine pregnancy test, and blood β-hCG test are completed via the green channel. (C) Admission 10 minutes: Upon confirmation, the OB/GYN doctor arrives at the resuscitation room (virtual ward) within 10 minutes. The trauma nurse monitors vital signs, and the IV access nurse establishes venous access. The emergency surgeon performs the initial assessment and provides necessary support. (D) Admission 25 minutes: The OB/GYN doctor re-evaluates and decides the treatment plan. Patients requiring surgery complete preoperative preparation and consent discussions within the virtual ward and are transported directly to the operating room by the team. Patients eligible for conservative treatment are transferred to the OB/GYN ward. (E) Admission 30 minutes: Patient enters the operating room. The principle of "treatment first, payment later" is implemented throughout the process. (The specific flowchart is shown in Fig. 2 . Differences between the two models are summarized in Table 1 .)

(6) Time to Definitive Diagnosis The time from the patient's first medical contact to the definitive diagnosis. (7) Time to Enter Operating Room The time from the definitive diagnosis of ectopic pregnancy to entering the operating room. (8) Patient and Family Satisfaction with Emergency Care A survey of patient and family satisfaction regarding the emergency response time, process, and success rate. 1.3 Statistical Methods Statistical analysis was performed using SPSS 21.0 software. Measurement data are expressed as mean ± standard deviation (x ± s), and intergroup comparisons were made using the t-test. Count data are expressed as number (percentage), and intergroup comparisons were made using the χ² test or Fisher's exact test. Ranked data were analyzed using the rank-sum test. A P value < 0.05 was considered statistically significant. 2. Results 2.1 Comparison of General Patient Data Between the Two Groups A total of 63 patients were included. There were no statistically significant differences between the two groups in age, vital signs at admission (body temperature, heart rate, respiration, blood pressure), or length of hospital stay (P > 0.05), indicating comparability. However, the total medical cost in the trauma care model group was significantly lower than that in the traditional model group (P = 0.002), and the fallopian tube preservation rate was significantly higher in the trauma care model group (43.8% vs. 19.4%, P = 0.034). Details are shown in Table 2 .

Discussion This study is the first to apply a structured emergency model integrating the concepts of the trauma green channel and the emergency virtual ward to the management of ectopic pregnancy. The results demonstrate that this model significantly shortens key in-hospital time points, increases the fallopian tube preservation rate, reduces medical costs, and improves patient satisfaction. The management of ectopic pregnancy is a race against time. Both domestic and international studies emphasize that the "golden window" from hospital admission to surgery critically impacts prognosis, particularly the preservation of fertility [16][17]. The traditional sequential, multi-department transfer process has inherent delays [18]. The novel model constructed in this study achieves process reengineering through three core initiatives: First, early warning and MDT linkage. Drawing on concepts like ACiLS for non-traumatic critical care[19][20], the alarm is activated upon triage suspicion, shifting from "initiation after confirmation" to "linkage after warning," placing MDT consultation at the forefront of decision-making, effectively reducing communication barriers and waiting times between departments. Second, spatial and resource integration. The "emergency virtual ward" brings the OB/GYN doctor's consultation space forward to the resuscitation room. Combined with the green channel ensuring priority for examinations, it realizes an efficient operational model where "the patient remains stationary, while information and doctors move," aligning well with the "one-stop" treatment concept pursued by modern emergency medicine [21][22]. Third, process standardization and team specialization. A fixed MDT team with clear division of responsibilities, supplemented by regular team collaboration training, ensures the orderliness and tacit understanding of the rescue process, consistent with the experiences reported by Zhao et al. et al.[10]and Liu and Bai [11] in trauma center construction. The observed higher fallopian tube preservation rate in the trauma care model group is likely attributable to the significantly earlier diagnosis and surgical intervention. When the ectopic pregnancy mass is treated before rupture or in the early stages of rupture, the opportunity to perform fertility-preserving surgery (such as salpingostomy) is greater[23][24]. Meanwhile, the efficiency gains from process optimization, avoiding unnecessary hospital days and related tests, likely contributed to the lower total medical cost in this group, consistent with the view that efficient healthcare models are often more cost-effective[25]. This study has several limitations. First, as a single-center retrospective study, potential selection bias exists, and the generalizability of the conclusions needs further verification. Second, the relatively small sample size may affect the statistical power of some subgroup analyses. Third, a detailed cost-effectiveness analysis of the two models was not performed. Finally, data on long-term postoperative fertility outcomes (such as intrauterine pregnancy rate, recurrent ectopic pregnancy rate) are lacking. Future research directions should include: conducting multicenter, prospective randomized controlled trials to provide higher-level evidence; expanding the sample size and performing subgroup analyses for patients with different severity levels; performing comprehensive health economic evaluations; and establishing long-term follow-up mechanisms to assess the model's long-term impact on patients' fertility quality and quality of life. 4. Conclusion The novel trauma emergency model for ectopic pregnancy, based on the trauma green channel and the emergency virtual ward in our hospital, significantly optimized the in-hospital emergency process, shortened key time points, reduced medical costs, and helped improve the rate of fertility preservation and patient satisfaction with emergency care through multidisciplinary collaboration, process reengineering, and resource integration. It provides an efficient and referable new management model for the emergency treatment of ectopic pregnancy.

Studies have shown that its occurrence is closely related to factors such as pelvic inflammatory disease, history of ectopic pregnancy, and the use of assisted reproductive technologies[2]. In recent years, with the trend of delayed childbearing and rising rates of pelvic infections, the global incidence of ectopic pregnancy is about 1%-2%, and the incidence in China also reaches 1.5%-2.0%. The incidence has increased 4\u0026ndash;6 fold over the past 30 years, making it one of the leading causes of maternal death in the first trimester, accounting for 2.7% of pregnancy-related deaths[3][4]. Once ruptured, ectopic pregnancy can lead to intra-abdominal hemorrhage and hemorrhagic shock, severely threatening the patient's life[5].\u003c/p\u003e \u003cp\u003eCurrently, the diagnosis of ectopic pregnancy primarily relies on transvaginal ultrasonography and dynamic monitoring of serum beta-human chorionic gonadotropin (β-hCG) levels[6]. Treatment options include medical management, surgical intervention (typically laparoscopy), and expectant management. The choice depends on the patient's hemodynamic status, β-hCG levels, size of the gestational mass, and fertility desires[7]. Regardless of the approach, the treatment principles revolve around three key goals: \"saving lives, removing the ectopic pregnancy, and preserving fertility\"[5]. Therefore, establishing an efficient and standardized in-hospital emergency process for early diagnosis and rapid intervention is crucial for improving prognosis and preserving reproductive potential[8][9].\u003c/p\u003e \u003cp\u003eAlthough mature \"green channel\" models for trauma, chest pain, and stroke have been established domestically and internationally, significantly improving treatment efficiency[10][11], the exploration of structured emergency systems specifically for ectopic pregnancy, a unique obstetric and gynecological emergency, remains insufficient. Traditional emergency models often suffer from delays due to imprecise triage, poor coordination between departments, and long waiting times for examinations[12]. Inspired by the multidisciplinary team (MDT) concept and process optimization principles of trauma centers[13][14], and leveraging the advantages of the emerging \"virtual ward\" in integrating medical resources[15], our hospital attempted to integrate the trauma green channel with the emergency virtual ward to create a dedicated emergency model for ectopic pregnancy. This study aims to evaluate the effectiveness of this novel model in improving the efficiency of the emergency process for ectopic pregnancy patients by comparing it with the traditional model.\u003c/p\u003e"},{"header":"1.

Initial diagnosis was made by rotating doctors in the emergency department. After diagnosis, patients transferred to the Obstetrics and Gynecology department on their own or accompanied by one nurse. The trauma center used a one-doctor, multiple-nurses model, but nurse roles were unclear, and team collaboration training was lacking.\u003c/p\u003e\n\u003cp\u003eNovel Model: An ectopic pregnancy MDT team was established, consisting of emergency surgeons, obstetrician-gynecologists, laboratory staff, and ultrasonographers. A fixed team model of \"two doctors and two nurses\" was adopted (one emergency surgeon, one obstetrician-gynecologist, one trauma nurse, one intravenous access nurse), with clearly defined responsibilities. In addition to monthly routine training and assessment, regular team simulation drills and specialized training for critically ill patient transport were conducted.\u003c/p\u003e\n\u003c/div\u003e\n\u003cdiv id=\"Sec6\" class=\"Section3\"\u003e\n\u003ch2\u003e1.2.2 Treatment Process\u003c/h2\u003e\n\u003cp\u003eTraditional Model: (1) Initial Assessment and Management: After the patient arrives at the hospital, triage staff inquire about the patient's general condition to preliminarily confirm the possibility of ectopic pregnancy and notify the emergency surgeon. (2) Subsequent Examinations: The doctor on duty conducts routine tests and examinations to confirm the diagnosis of ectopic pregnancy, with priority given to critically ill patients. However, this expedited service is limited to within the emergency department. (3) Ectopic Pregnancy Alert Activation: After confirmation, the obstetrics and gynecology department is contacted for admission. Emergency medical staff assist with the transfer to the obstetrics and gynecology ward throughout the process. (4) Subsequent Treatment: After entering the ward, subsequent treatment is led by the obstetrics and gynecology doctor on duty.\u003c/p\u003e\n\u003cp\u003eNovel Model: (1) Ectopic Pregnancy Alert Activation: After the patient arrives at the hospital, well-trained triage staff inquire about the patient's general condition to preliminarily confirm the possibility of ectopic pregnancy and notify the emergency surgeon, thereby immediately activating the ectopic pregnancy alert. (2) Initial Assessment and Management: The emergency surgeon assesses the patient's general condition. The patient is moved to the resuscitation room for vital signs monitoring. (3) Subsequent Examinations: Rapid tests and examinations are performed via the green channel. (4) Subsequent Treatment: The patient is admitted to the emergency virtual ward. An obstetrics and gynecology doctor arrives on site within 10 minutes to assess the patient for subsequent treatment. A hospital-wide ectopic pregnancy green channel service system is established to ensure priority treatment for ectopic pregnancy patients across all relevant departments. In cases requiring urgent blood transfusion, the emergency surgeon or nurse can promptly notify the blood bank by phone to ensure timely transfusion. Patients with surgical indications receive priority for surgery. The obstetrics and gynecology doctor completes preoperative preparation in the resuscitation room via the virtual ward system, and the patient is transported directly from the emergency resuscitation room to the operating room within 30 minutes of admission to shorten surgical wait times. Furthermore, if patients face difficulties with medical payments, the principle of \"treat first, pay later\" applies to avoid delays in treating critically ill patients. Patients assessed as suitable for conservative treatment are transferred from the virtual ward to the obstetrics and gynecology ward for subsequent management.\u003c/p\u003e\n\u003c/div\u003e\n\u003cdiv id=\"Sec7\" class=\"Section3\"\u003e\n\u003ch2\u003e1.2.3 Emergency Protocol\u003c/h2\u003e\n\u003cp\u003e\u003cstrong\u003eTraditional Model\u003c/strong\u003e\u003c/p\u003e\n\u003cp\u003eTriage \u0026rarr; Reception by emergency surgeon \u0026rarr; Ordering tests \u0026rarr; Patient completes tests independently \u0026rarr; Contact Obstetrics \u0026amp; Gynecology after confirmation \u0026rarr; Transfer to ward \u0026rarr; Treatment arranged by OB/GYN doctor.\u003c/p\u003e\n\u003c/div\u003e\n\u003c/div\u003e\n\u003cdiv class=\"Heading\"\u003e\u003cstrong\u003eNovel Model\u003c/strong\u003e:\u003c/div\u003e\n\u003cp\u003e(A) Admission 0 minutes: Experienced triage staff activate the alarm and initiate the MDT upon initial suspicion of ectopic pregnancy.\u003c/p\u003e\n\u003cp\u003e(B) Admission 5 minutes: Patient enters the resuscitation room.

Discussion","content":"\u003cp\u003eThis study is the first to apply a structured emergency model integrating the concepts of the trauma green channel and the emergency virtual ward to the management of ectopic pregnancy. The results demonstrate that this model significantly shortens key in-hospital time points, increases the fallopian tube preservation rate, reduces medical costs, and improves patient satisfaction.\u003c/p\u003e \u003cp\u003eThe management of ectopic pregnancy is a race against time. Both domestic and international studies emphasize that the \"golden window\" from hospital admission to surgery critically impacts prognosis, particularly the preservation of fertility [16][17]. The traditional sequential, multi-department transfer process has inherent delays [18]. The novel model constructed in this study achieves process reengineering through three core initiatives: First, early warning and MDT linkage. Drawing on concepts like ACiLS for non-traumatic critical care[19][20], the alarm is activated upon triage suspicion, shifting from \"initiation after confirmation\" to \"linkage after warning,\" placing MDT consultation at the forefront of decision-making, effectively reducing communication barriers and waiting times between departments. Second, spatial and resource integration. The \"emergency virtual ward\" brings the OB/GYN doctor's consultation space forward to the resuscitation room. Combined with the green channel ensuring priority for examinations, it realizes an efficient operational model where \"the patient remains stationary, while information and doctors move,\" aligning well with the \"one-stop\" treatment concept pursued by modern emergency medicine [21][22]. Third, process standardization and team specialization. A fixed MDT team with clear division of responsibilities, supplemented by regular team collaboration training, ensures the orderliness and tacit understanding of the rescue process, consistent with the experiences reported by Zhao et al. et al.[10]and Liu and Bai [11] in trauma center construction.\u003c/p\u003e \u003cp\u003eThe observed higher fallopian tube preservation rate in the trauma care model group is likely attributable to the significantly earlier diagnosis and surgical intervention. When the ectopic pregnancy mass is treated before rupture or in the early stages of rupture, the opportunity to perform fertility-preserving surgery (such as salpingostomy) is greater[23][24]. Meanwhile, the efficiency gains from process optimization, avoiding unnecessary hospital days and related tests, likely contributed to the lower total medical cost in this group, consistent with the view that efficient healthcare models are often more cost-effective[25].\u003c/p\u003e \u003cp\u003eThis study has several limitations. First, as a single-center retrospective study, potential selection bias exists, and the generalizability of the conclusions needs further verification. Second, the relatively small sample size may affect the statistical power of some subgroup analyses. Third, a detailed cost-effectiveness analysis of the two models was not performed. Finally, data on long-term postoperative fertility outcomes (such as intrauterine pregnancy rate, recurrent ectopic pregnancy rate) are lacking.\u003c/p\u003e \u003cp\u003eFuture research directions should include: conducting multicenter, prospective randomized controlled trials to provide higher-level evidence; expanding the sample size and performing subgroup analyses for patients with different severity levels; performing comprehensive health economic evaluations; and establishing long-term follow-up mechanisms to assess the model's long-term impact on patients' fertility quality and quality of life.\u003c/p\u003e"},{"header":"4.

Its incidence is increasing globally, and early diagnosis and timely intervention are crucial for reducing mortality and preserving fertility. This study aims to investigate the role of a novel emergency model based on the trauma green channel and an emergency virtual ward in improving the treatment efficiency for patients with ectopic pregnancy.\u003c/p\u003e\u003ch2\u003eMethods\u003c/h2\u003e \u003cp\u003eA retrospective study was conducted on 63 ectopic pregnancy patients who underwent emergency surgery in our hospital between January 2023 and April 2025. They were divided into a traditional model group (31 cases) and a trauma care model group (32 cases). General clinical data and eight emergency quality control indicators were collected and compared, including patient admission time, time to establish effective circulatory access, time to perform color Doppler ultrasound, time to obtain urine pregnancy test results, time to obtain serum β-hCG results, time to definitive diagnosis, time to enter the operating room, and satisfaction score with emergency care.\u003c/p\u003e\u003ch2\u003eResults\u003c/h2\u003e \u003cp\u003eNo significant differences were found between the two groups in terms of age, vital signs, or length of hospital stay (P\u0026thinsp;\u0026gt;\u0026thinsp;0.05). The trauma care model group had significantly lower total medical costs (P\u0026thinsp;=\u0026thinsp;0.002) and a higher rate of fallopian tube preservation (43.8% vs. 19.4%, P\u0026thinsp;=\u0026thinsp;0.034) compared to the traditional model group. Furthermore, the trauma care model group demonstrated significantly better results in all eight emergency quality control indicators (P\u0026thinsp;\u0026lt;\u0026thinsp;0.05), and patient and family satisfaction with the emergency process was also significantly higher (P\u0026thinsp;=\u0026thinsp;0.013).\u003c/p\u003e\u003ch2\u003eConclusion\u003c/h2\u003e \u003cp\u003eThe novel trauma emergency model for ectopic pregnancy, based on the trauma green channel and the emergency virtual ward, significantly optimized the emergency process, shortened key time points, reduced medical costs, and helped improve the rate of fertility preservation and patient satisfaction with emergency care. It demonstrates good value for clinical application and promotion.\u003c/p\u003e","manuscriptTitle":"A Novel Model Based on the Trauma Green Channel and Emergency Virtual Ward Improves the Efficiency of the Emergency Process for Ectopic Pregnancy Patients","msid":"","msnumber":"","nonDraftVersions":[{"code":1,"date":"2026-02-11 16:56:44","doi":"10.21203/rs.3.rs-8547410/v1","editorialEvents":[{"type":"communityComments","content":0}],"status":"published","journal":{"display":true,"email":"
