This study was conducted using the chapter on Scoping Reviews in the JBI Manual for Evidence Synthesis ( Peters et al., 2024 ). The protocol was published in Open Science Framework in May of 2023; https://doi.org/10.17605/OSF.IO/VD6CB . The manuscript has been reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR) checklist ( Tricco et al., 2018 ) (Supplementary material 1). Eligible studies were published and peer-reviewed qualitative, quantitative and mixed-method empirical studies available in full text. No limits were applied to publication period or language. The participants were adult patients (≥ 18 years) undergoing gynaecological ambulatory surgery. Relevant outcomes were data on all harmful incidents reported to have occurred following the ambulatory surgery treatment. There were no restrictions regarding when the harmful incidents occurred following surgery, nor who reported them, such as patients, healthcare professionals or the researchers. This scoping review focused on surgically complex treatments. Thus, less extensive procedures such as hysteroscopies, colposcopies and interventions for urinary incontinence were excluded, except when performed as concurrent treatment. Studies focusing on drugs, anaesthesia, medical devices, reviews, opinion papers, dissertations, grey literature, white papers, books, book chapters, case studies, abstracts, protocols, editorials and commentaries were excluded. The systematic literature search was conducted by an academic librarian (GTJ), in accordance with the stages recommended by JBI ( Peters et al., 2024 ). The PCC elements of this scoping review, Population: adult patients (≥18 years), Concept: harmful incidents and Context: following discharge from gynaecological ambulatory surgery, were used to identify search terms for the initial limited search conducted in databases MEDLINE and CINAHL. The titles and abstracts of records retrieved from this initial search were reviewed and the search strategy was developed from text words and index terms identified in relevant records (GTJ, CWT). The final search strategy was peer-reviewed by a second academic librarian ( McGowan et al., 2016 ). The systematic literature search was originally conducted in May of 2023 and updated in February of 2025 in the databases MEDLINE (through Ovid), Embase (through Ovid), CINAHL (through EBSCOhost), Cochrane Library, Scopus and Web of Science. Documentation of the systematic literature search is provided in Supplementary material 2. The reference lists of the included studies were manually screened for additional eligible sources (backward chaining) (CWT) ( Peters et al., 2024 ). A total of 17,332 records were identified from the systematic literature search and uploaded to the EndNote reference management tool (version 20), where 8773 duplicates were removed ( Akers, 2017 ; Bramer et al., 2016 ). Five additional duplicates were removed in the review management software DistillerSR , where the remaining records were transferred for study selection and data extraction. Throughout the subsequent process of study selection, the involved reviewers were blinded to each other’s decisions of inclusion or exclusion and conflicts of eligibility were resolved by consensus ( Peters et al., 2024 ). Three reviewers tested the selection strategy for screening of study titles and abstracts by use of the eligibility criteria and an accompanying elaboration document (CWT, MKG, SBB). The three reviewers’ decisions of inclusion or exclusion were unanimous for 19 of the 25 studies that were randomly selected for the test (76 %), which according to JBI is a sufficiently high level of agreement to start screening ( Peters et al., 2024 ). The studies with conflicting decisions were discussed, from which it was established that less extensive surgical procedures were to be excluded. The three reviewers then went on to complete the screening of remaining titles and abstracts, each study being assessed by two reviewers. Following screening, the number of potentially relevant studies was significantly reduced ( Fig. 1 ). Thus, only two of the reviewers (CWT, SBB) went on to conduct the full text assessment and determine the final inclusion of studies in the scoping review. A list of the studies that were excluded based on full-text assessment and reasons for exclusion is provided in Supplementary material 3. One study was excluded because the types of gynaecological treatments included were not reported and the corresponding author was unable to provide additional information to verify eligibility ( Bruun et al., 2023 ).

This work is licensed under CC BY 4.0. The data extraction form was developed in accordance with JBI’s manual and piloted on three studies by two reviewers (CWT, SBB) ( Peters et al., 2024 ). From piloting the form, the following adjustments were made: The item ‘Objective(s) of the study’ was included in the section ‘Methodology’, the items ‘Methods of surgery’ and ‘Time of data collection’ was added to the section ‘Participants’, and the two items for types and occurrences of harmful incidents under ‘Concept’ were merged to avoid repetition (Supplementary material 4). To ensure that all relevant data were extracted from the included studies, the results and discussions as well as relevant tables and supplementary materials were reviewed. For the studies reported in English, two reviewers (CWT, SBB) separately extracted data from each study. Reviewer CWT then assessed both reviewers completed forms. If discrepancies were found, the two reviewers (CWT, SBB) discussed for clarification. Four of the included studies were reported in Spanish or French ( Benoit et al., 2022 ; Calle et al., 2011 ; Guerrero-Machado et al., 2021 ; Rambeaud et al., 2017 ). For these studies, the quality of data translation and extraction was ensured by contributor MAHM, who is fluent in both languages and knowledgeable of the methods and concepts of this scoping review. Findings on study characteristics and the surgical treatments are presented in text, tables and figures. By deductive approach, all of the identified harmful incidents are mapped into main and subcategories under three dimensions of harm based on WHO’s Conceptual Framework for the International Classification for Patient Safety (2010); 1) physiological harm, 2) psychological harm and 3) social harm. In addition, the main categories of harmful incidents are mapped to provide an overview of the surgical treatments following which they occurred.

A total of 41 studies were included in this scoping review. The study selection process is presented in a PRISMA flow diagram ( Fig. 1 ). Each included study is assigned an identification number (study ID) in Table 1 . The studies were conducted in eight different Western and developed countries: The United States of America (26/41), Canada (5/41), Colombia (3/41), Denmark (2/41), France (2/41), the United Kingdom (1/41), Italy (1/41) and Spain (1/41). A total of 34,269 participants were included in the studies, with sample sizes ranging from 10 to 11,334. All the studies were quantitative, of which 11 had prospective designs (study IDs 5, 6, 11, 13–15, 25, 26, 31, 37, 38). The analysed data had been retrieved between January of 1991 to October of 2022, mostly from medical records and registries. The data was collected from the patients between 2 weeks to 12 months postoperatively, most commonly for approximately 30 days (19/41) ( Table 1 ). Five studies did not report the follow-up time for data collection (study IDs 9, 12, 21, 25, 32). More details on study characteristics are provided in Table 1 . The samples in two of the studies are likely to overlap (study IDs 27 and 30). Therefore, only the number of incidents extracted from Philp et al. (study ID 30) are included in counts of the harmful incidents that were reported in both studies, as these data were collected more recently and over a longer period.

Study identification numbers (study ID), study characteristics and outcomes relevant to the scoping review. An overview of the surgical approaches in the included studies and the treatments conducted with each approach is presented in Table 2 . Four studies included surgeries by vaginal approach only (study IDs 7, 11, 37, 38). Of the 37 studies that included laparoscopies, 20 specified that robot assisted surgeries were conducted (study IDs 2, 3, 9, 10, 12, 14, 17–20, 22–24, 28, 33–35, 39–41). While three studies reported to have included laparoscopic assisted vaginal hysterectomy (study IDs 24, 35, 41), two studies specified to have excluded this surgical approach (study IDs 13, 29). Furthermore, four of the studies that included hysterectomy by laparoscopic approach noted to have performed vaginal specimen retrieval (study IDs 15, 23, 32, 33). Mini laparotomies were usually conducted in combination with laparoscopy and for specimen retrieval in studies including hysterectomy (study IDs 6, 15, 22, 23, 26), salpingo-oophorectomy (study IDs 15, 22, 23, 26), lymphadenectomy (study IDs 22, 23) and myomectomy (study ID 21).

The main surgical treatments conducted were hysterectomy, pelvic organ prolapse surgery, salpingo-oophorectomy, lymphadenectomy, trachelectomy, myomectomy, ovarian cyst removal and sterilisation. These treatments were also conducted concurrently with one another, as shown in Fig. 2 . Other concurrent gynaecological and non-gynaecological treatments were procedures for urinary incontinence (study IDs 11, 12, 14, 16, 19, 38), hysteroscopy (study IDs 9, 21), cystoscopy (study ID 17), exploration of the abdominal cavity, salpingectomy (study IDs 9, 38), oophorectomy (study ID 38), adhesiolysis (study IDs 1, 22), ureterolysis (study ID 22), chromotubation, resection of endometriosis (study ID 9), appendectomy (study IDs 10, 23, 34), hernia repair (study ID 22), omentectomy (study IDs 10, 23, 27, 34), omental surgery (study ID 22), omental biopsy (study ID 23), peritoneal sampling (study IDs 1, 23), sentinel lymph node biopsy (study ID 30), staging of borderline ovarian tumour (study ID 1) and debulking (removal of metastases) (study ID 34). Surgical treatments for oncologic indications were included in 13 of the studies (study IDs 1, 10, 17, 22, 23, 27, 28, 30, 32–34, 39, 41).

Studies that did not report number of incidents are also included in the last column. An X in the table indicates that the harmful incident was reported to have occurred in studies listed in the last column but the number of incidents was not reported. Out of all the main categories of harmful incidents, postoperative infections were reported across the highest number of studies (32/41), followed by bleeding (23/41) and pain (22/41). Urinary tract infection was the subcategory of postoperative infections reported both in the highest number of studies (19/41) and with the highest number of incidents (549/1038 total incidents of postoperative infections), followed by surgical site infection (18/41 studies, 310/1038 total incidents of postoperative infections). The only specified surgical site of infection was the vaginal cuff. The vaginal cuff was also the only specified surgical site where dehiscence was reported. Another identified surgical site problem was fistula. Fistulae were reported from five studies, of which four specified that the fistulae were connected to the urinary tract (study IDs 27, 29, 30, 32). In one of these studies, ureterovaginal fistulae had been the cause of vaginal discharge (study ID 30). Vaginal discharge was identified in three of the included studies. Among the studies that reported of bleeding (23/41), 13 specified vaginal bleeding to have occurred. Regarding harmful incidents of the urinary system, urinary retention was the subcategory reported in both the highest number of studies (7/41) and with the most incidents (14/33 total incidents of the urinary system). Constipation was the subcategory of harmful incidents related to the gastrointestinal system identified from the highest number of studies (4/41), while small bowel obstruction had the highest number of incidents (9/32 total incidents of the gastrointestinal system). For subcategories of harmful incidents in the respiratory system, pneumonia was reported across the highest number of studies (7/41) and with the most incidents (12/29 total incidents of the respiratory system). Most harmful incidents of the circulatory system were mapped under the subcategory for thromboembolic disease (65/93 total incidents of the circulatory system), which included 29 incidents of pulmonary embolism and 27 incidents of venous thromboembolism. Thromboembolic disease was also the subcategory of harm in the circulatory system that had been reported across the highest number of studies (11/41). Pain was reported from more than half of the included studies (22/41), out of which only seven specified the site or cause of pain. The highest number of incidents of pain were in the subcategory for shoulder pain (52/192 total incidents of pain), which were all identified from one study. The site of pain specified across the highest number of studies was the abdomen (5/41), which had 47 reported incidents (out of 192 total incidents of pain). The one reported incident of pain due to tethering of a sacral nerve occurred in a study that included pelvic organ prolapse surgery and had resulted in additional surgery for removal of a uterosacral suspension suture. The four incidents of nerve injury were reported from different studies which all included hysterectomy conducted by laparoscopic approach (study IDs 17, 22, 24, 38). Five studies reported incidents of physiological harm identified by patients that do not fit under any of the other main categories of harmful incidents. Therefore, these harmful incidents are mapped in a separate main category ( Table 3 ). Incidents of ‘suspected recurrence’, as defined in the reporting study, are assumed to refer to the recurrence of pelvic organ prolapse, the condition for which the patients were treated (study ID 7). The incidents of lymphedema, pelvic fluid collection and death had occurred in studies that included surgical treatment for oncologic indications. One patient had died within two weeks (study ID 17) and another within 30 days after the surgery (study ID 28). For the six remaining incidents, the time from surgery to death had not been noted (study ID 41). None of the studies reported cause of death. The only psychological harm identified to have occurred following gynaecological ambulatory surgery was anxiety, with all six incidents having been reported from one study (study ID 1). The cause of anxiety was not described in the reporting study.

Ambulatory surgery is elective surgical treatment without an overnight stay in hospital ( World Health Organization et al., 2007 ). The development and expansion of ambulatory surgery practice over the past decades has been encouraged by incentives related to increased efficiency and less use of healthcare resources ( OECD, 2023 ). Simultaneously, advancements in minimally invasive surgical techniques and anaesthesiology have maintained the safety of ambulatory surgery ( Laaboub et al., 2020 ; OECD, 2023 ). Thus, gynaecological surgeries such as hysterectomy, myomectomy, pelvic reconstructive surgery and laparoscopic surgery with or without robotic assistance are considered safe as ambulatory surgery treatment ( M. L. Fowler et al., 2022 ; Madden et al., 2019 ; Robison et al., 2022 ). Despite the advances to ensure that gynaecological ambulatory surgery is as safe, if not safer than in-patient treatment, patient safety incidents continue to be of critical concern due to the occurrence of harmful incidents following discharge ( Ellinides et al., 2022 ; Emery et al., 2024 ; M. L. Fowler et al., 2022 ). Harmful incidents are classified as patient safety incidents that result in patient harm, encompassing both preventable harmful incidents (adverse events) and non-preventable harmful incidents (adverse reactions) ( World Health Organization, 2020 ). In context of patient safety, the World Health Organization (WHO) (2010) refers to harm as impairment of body structure or function and harmful effects there from. Harm can be physiological, psychological or social, including injury, disease, suffering, disability that restricts participation in society and death ( World Health Organization, 2010 ). After gynaecological ambulatory surgery, harmful incidents such as bleeding, pain, infections, wound problems and incidents related to the gastrointestinal, urinary and cardiovascular systems have been reported to occur and result in readmissions and reoperations ( Matern et al., 2020 ; Robison et al., 2022 ; Zillioux et al., 2021 ). Furthermore, syntheses of evidence from qualitative studies on ambulatory surgery treatments within various surgical specialties have found that patients experience incidents such as reduced ability to participate in social activities and feelings of sadness, anxiety and abandonment following discharge ( Sig et al., 2025 ; Thoen et al., 2023 ). Thus, harmful incidents not only increase costs and the use of healthcare resources, but also affect treatment outcomes and the quality of recovery. Therefore, it is essential to maintain a continued focus on patient safety to ensure that the risk of unnecessary harm associated with gynaecological ambulatory surgery is reduced to an acceptable minimum ( World Health Organization, 2010 ). To improve patient safety in outpatient settings such as ambulatory surgery practice, the harmful incidents occurring should be addressed ( Levine et al., 2024 ). However, efforts to improve clinical practice should be based on knowledge of the realities and challenges of these harmful incidents ( Dixon-Woods, 2010 ). From a preliminary search in MEDLINE, Embase, Cochrane, CINAHL, Scopus and Prospero, and to the best of our knowledge, there are no previous or ongoing reviews on harmful incidents after gynaecological ambulatory surgery. Thus, the aim of this scoping review was to map the types and frequencies of harmful incidents identified in research to occur following gynaecological ambulatory surgery.

In this scoping review, most of the harmful incidents identified to have occurred following gynaecological ambulatory surgery were mapped as physiological harm, including postoperative infections, bleeding and pain. Anxiety was the only identified psychological harm, and no incidents of social harm was reported in the included studies. More research is needed on psychological and social harm as well as medication related harmful incidents following gynaecological ambulatory surgery. Moreover, to expand current knowledge, qualitative studies should be conducted to explore harmful incidents that are identified by patients, their caregivers and healthcare professionals. The findings of this scoping review can provide healthcare professionals with knowledge and awareness of harmful incidents occurring in gynaecological ambulatory surgery practice. Insight from the current study can also be used to enhance information provision to patients. Initially, studies on ambulatory surgery within all surgical specialties were eligible. However, screening of titles and abstracts from the systematic literature search showed this would have resulted in an extensive volume of studies and data to be reviewed. After discussion between authors CWT, MKG, SW and SBB, the scope was thus limited to gynaecological ambulatory surgeries.

In this scoping review, harmful incidents occurring following gynaecological ambulatory surgery were identified from 41 included studies. Most of the harmful incidents were mapped under the dimension for physiological harm. Anxiety was the only psychological harm identified. None of the included studies reported of social harm ( World Health Organization, 2010 ). Postoperative infections, bleeding and pain were the most reported harmful incidents, both in terms of the number of studies in which they had been identified and the number of incidents reported across all the included studies. These are harmful incidents anticipated to occur following surgical treatment within gynaecology as well as other surgical specialties, and therefore expected findings in this scoping review ( Dencker et al., 2021 ; Kaya et al., 2021 ; Thurston et al., 2023 ). All incidents of vaginal bleeding and vaginal cuff infection were reported form studies in which hysterectomy was conducted, either by laparoscopic or vaginal approach, and all incidents of vaginal cuff dehiscence occurred in studies that included laparoscopic hysterectomy. When performing total hysterectomy, a circumferential incision is made around the cervix to remove the uterus, after which the incision at the vaginal top is sutured ( Rothrock, 2023 ). Hence, bleeding, infection and dehiscence of the vaginal cuff can occur postoperatively. Hysterectomies were also conducted in all studies reporting of fistulae connected to the urinary tract. Previous research has found hysterectomy to be the most common gynaecological cause of vesicovaginal fistula formation ( Shrestha et al., 2022 ). There were no details to describe the reported incidents of nerve injury, back or shoulder pain, except that all had been identified from studies including laparoscopy. During laparoscopic gynaecological surgery, the patients are typically placed in Trendelenburg and lithotomy positioning ( Rothrock, 2023 ). A systematic review has shown that peripheral nerve injuries of the upper extremities are most common after surgery in the Trendelenburg position, and peripheral nerve injuries of the lower extremities are most common following a lithotomy positioning ( Bentsen et al., 2024 ). The same systematic review also found that back and shoulder pain was related to the Trendelenburg position ( Bentsen et al., 2024 ). Shoulder pain is a common harmful incident associated with residual gas following laparoscopic surgery. Some research has also suggested that improper surgical positioning can worsen the shoulder pain ( Zhao et al., 2025 ). The eight incidents of death occurred after ambulatory surgery for oncologic indications, which was still concluded in the reporting studies to be as safe as in-patient treatment. Other research has found disseminated cancer to be among the most significant preoperative predictors of postoperative mortality ( Alder et al., 2023 ). Furthermore, studies have shown that postoperative harmful incidents increased the risk of death, both after planned surgery in general and ambulatory surgery in particular ( Alder et al., 2023 ; A. J. Fowler et al., 2022 ). In the current study, however, the cause of death and occurrence of other harmful incidents in these patients were not reported. The one reported incident of medication misuse of diclofenac had resulted in readmission of the patient. Other research has shown that in outpatient settings such as ambulatory surgery practice, medication related harmful incidents constitute major safety issues and are commonly the reason for hospital readmissions ( de Bienassis et al., 2022 ; Levine et al., 2024 ; Wasserman et al., 2024 ). Therefore, the scarcity of harmful incidents related to medications in this scoping review is interesting and indicates there is a gap of knowledge. In the study reporting anxiety, which is the only psychological harm identified in this scoping review, part of the sample underwent salpingo-oophorectomy. Anxiety following oophorectomy is suggested to be a psychological effect of surgical menopause due to hormonal changes resulting from removal of the ovaries ( Gölbaşı et al., 2023 ; Trister et al., 2021 ). No social harm was identified in this scoping review. According to WHO (2010) , limitations and restrictions on participation in society due to past or present harm are considered social harm. Qualitative research has shown that patients experience dependency on others, restricted mobility and feelings of abandonment during the recovery at home following ambulatory surgery treatments within various surgical specialties ( Larsson et al., 2022 ; Sig et al., 2025 ; Thoen et al., 2023 ). This indicates that social harm does occur in ambulatory surgery practice but is likely underreported. Inconsequent definition of length of stay in ambulatory surgery practice can affect the findings of studies on harmful incidents ( Bovonratwet et al., 2017 ). It is therefore a strength that only studies in which patients were discharged on the same calendar day as undergoing the surgery were included in this scoping review, ensuring that the findings are relevant to the concept of interest. However, the included studies reported harmful incidents in different ways. For example, while some studies focused on specific harmful incidents, others only reported the main category of harmful incidents without further details. Also, the number of incidents were not always provided. Furthermore, inconsistent definitions and terminologies were used for the harmful incidents studied. These issues are known to challenge assessments of surgical quality and affected the analysis and findings of this scoping review ( Dindo and Clavien, 2008 ). Several of the studies included multiple surgical approaches and treatments, which were often conducted concurrently. Harmful incidents occurring following the various approaches and treatments were not differentiated in the study results. Therefore, there are limited findings from this scoping review to provide detailed knowledge on harmful incidents that were specific to each of the surgical treatments and approaches. Moreover, as the included studies were all conducted in western and developed countries, the findings may not reflect harmful incidents occurring in parts of the world where gynaecological ambulatory surgery is practiced differently or in countries with lower socioeconomic development. Most of the included studies used data from medical records and registries that were not particular to gynaecological or ambulatory surgery. Consequently, this scoping review most likely does not provide a complete overview of harmful incidents that are particular to gynaecological or ambulatory surgery. Furthermore, the predominance of studies based on registries and medical records and lack of qualitative studies may explain why evidence regarding the occurrence of psychological and social harm was mostly absent. No qualitative studies were eligible in this scoping review as those identified as potentially relevant included less extensive gynaecological procedures or surgeries of other surgical specialties. This is considered a limitation because the experiences and meanings of patients, caregivers and healthcare professionals are important for identifying a wider spectrum of harmful incidents and opportunities for improving safety in gynaecological ambulatory surgery practice ( Carayon et al., 2006 ; Levine et al., 2024 ; Salwei et al., 2023 ).
