STUDY QUESTION: What is the additional value of the comprehensive complication index (CCI) and ClassIntra system (classification for intraoperative adverse events (ioAEs)) in adverse event (AE) reporting in (deep) endometriosis (DE) surgery compared to only using the Clavien-Dindo (CD) system? SUMMARY ANSWER: The CCI and ClassIntra are useful additional tools alongside the CD system for a complete and uniform overview of the total AE burden in patients with extensive surgery (such as DE), and with this uniform data registration, it is possible to provide greater insight into the quality of care. WHAT IS KNOWN ALREADY: Uniform comparison of AEs reported in the literature is hampered by scattered registration. In endometriosis surgery, the usage of the CD complication system and the CCI is internationally recommended; however, the CCI is not routinely adapted in endometriosis care and research. Furthermore, a recommendation for ioAEs registration in endometriosis surgery is lacking, although this is vital information in surgical quality assessments. STUDY DESIGN, SIZE, DURATION: A prospective mono-center study was conducted with 870 surgical DE cases from a nonuniversity DE expertise center between February 2019 and December 2021. PARTICIPANTS/MATERIALS, SETTING, METHODS: Endometriosis cases were collected with the EQUSUM system, a publicly available web-based application for registration of surgical procedures for endometriosis. Postoperative adverse events (poAEs) were classified with the CD complication system and CCI. Differences in reporting and classifying AEs between the CCI and the CD were assessed. ioAEs were assessed with the ClassIntra. The primary outcome measure was to assess the additional value toward the CD classification with the introduction of the CCI and ClassIntra. In addition, we report a benchmark for the CCI in DE surgery. MAIN RESULTS AND THE ROLE OF CHANCE: A total of 870 DE procedures were registered, of which 145 procedures with one or more poAEs, resulting in a poAE rate of 16.7% (145/870), of which in 36 cases (4.1%), the poAE was classified as severe (Grade 3b). The median CCI (interquartile range) of patients with poAEs was 20.9 (20.9-31.7) and 33.7 (33.7-39.7) in the group of patients with severe poAEs. In 20 patients (13.8%), the CCI was higher than the CD because of multiple poAEs. There were 11 ioAEs reported (11/870, 1.3%) in all procedures, mostly minor and directly repaired serosa injuries. LIMITATIONS, REASONS FOR CAUTION: This study was conducted at a single center; thus, trends in AE rates and type of AEs could differ from other centers. Furthermore, no conclusion could be drawn on ioAEs in relation to the postoperative course because the power of this database is not robust enough for that purpose. WIDER IMPLICATIONS OF THE FINDINGS: From our data, we would advise to use the Clavien-Dindo classification system together with the CCI and ClassIntra for a complete overview of AE registration. The CCI appeared to provide a more complete overview of the total burden of poAEs compared to only reporting the most severe poAEs (as with CD). If the use of the CD, CCI, and ClassIntra is widely adapted, uniform data comparison will be possible at (inter)national level, providing better insight into the quality of care. Our data could be used as a first benchmark for other DE centers to optimize information provision in the shared decision-making process.

OBJECTIVES: Linkage of safety data to patient experience data may provide information to improve surgical care. This retrospective observational study aimed to assess associations between complications, incidents, patient-reported problems, and overall patient experience. METHODS: Routinely collected data from safety reporting on complications and incidents, as well as patient-reported problems and experience on the Picker Patient Experience Questionnaire 15, covering seven experience dimensions, were linked for 4236 surgical inpatients from an academic center (April 2014-December 2015, 41% response). Associations between complication and/or incident occurrence and patient-reported problems, regarding risk of nonpositive experience (i.e., grade of 1-5 of 10), were studied using multivariable logistic regression. RESULTS: Patient-reported problems were associated with occurrence of complications/incidents among patients with nonpositive experiences (odds ratio [OR] = 2.8, 95% confidence interval [CI] = 1.6-4.9), but not among patients with positive experiences (OR = 1.0, 95% CI = 0.6-1.5). For each experience dimension, presence of patient-reported problems increased risk of nonpositive experience (OR range = 2.7-4.4). Patients with complications or incidents without patient-reported problems were at lower risk of a nonpositive experience than patients with neither complications/incidents nor reported problems (OR = 0.5; 95% CI = 0.3-0.9). Occurrence of complications/incidents only increased risk of nonpositive experience when patients also had problems on "continuity and transition" or "respect for patient preferences" dimensions. CONCLUSIONS: Linking safety data to patient experience data can reveal ways to optimize care. Staff seem able to ensure positive patient experiences despite complications or incidents. Increased attention should be paid to respecting patient preferences, continuity, and transition, particularly when complications or incidents occur.

Objective It remains unclear to what extent the morbidity and mortality conference (M&M) meets the objective of improving quality and safety of patient care. It has been suggested that M&M may be too focused on individual performance, hampering system-level improvement. The aim of this study was to assess focus and sustainability of lessons for patient care that were derived from M&M. Methods This is an observational study of routinely collected data on evaluated complications and identified lessons at surgical M&M for 8 years, assessing type and recurrence of lessons and cases from which these were drawn. Semistructured interviews with clinicians were qualitatively analyzed to explore factors contributing to lesson focus and recurrence. Results Three hundred eighteen lessons were drawn from 10,883 evaluated complications, primarily for those that were more severe, related to surgical or other treatment, and occurring in nonemergent, lower risk cases (all P < 0.001). Most lessons targeted intraoperative (43%) rather than preoperative or postoperative care as well as specifically technical (87%) and individual-level issues (74%). There were 43 recurring lessons (14%), mostly about postoperative care (47%) and medication management (50%). Interviewed clinicians attributed the intraoperative, technical focus primarily to greater appeal and control but identified an array of factors contributing to lesson recurrence, such as typical staff turnover in teaching hospitals. Conclusions This study provided empirical evidence that learning at M&M has a tendency to focus on intraoperative, technical performance, with challenges to sustain lessons for more system-level issues. Morbidity and mortality conference formats need to anticipate these tendencies to ensure a wide focus for learning with lasting and wide impact. @en

Background and objective Incident, adverse event (AE) and complaint data are typically used separately, but may be related at the patient level with one event triggering a cascade of events, ultimately resulting in a complaint. This study examined relations between incidents, AEs and complaints that co-occurred in admissions. Methods Independently and routinely collected incident, AE and complaint data were retrospectively linked for surgical admissions in an academic centre (2008-2014). Two investigators reviewed whether incidents/AEs in admissions were clinically related and in what sequence (incident preceding vs following AE). Likelihood of occurrence of AEs and AE cascades (ie, ≥3 AEs) was studied using logistic regression analyses. Results Complaints were filed for 33 (0.1%) of 26 383 admissions. Complaints filed by patients with incidents and/or AEs (n=13) mostly addressed quality/safety problems, whereas other complaints mostly addressed relationship problems. Incidents and AEs co-occurred in 730 (2.8%) admissions, which seemed clinically related in 34% of these cases. Incidents with related AEs preceded as well as followed AEs (56.6%/44.4%). Patients with incidents were at greater risk of AEs than patients without incidents, even for seemingly unrelated AEs (OR 1.4; 95% CI 1.3 to 1.6). Risk of AE cascades was greater when patients with AEs also had incidents, regardless of whether these seemed related (unrelated: OR 2.0; 95% CI 1.6 to 2.5; related: OR 5.7; 95% CI 4.3 to 7.4) or whether incidents preceded or followed AEs in these admissions (53% vs 52%, P>0.05). Conclusions Patient-level linkage of incident, AE and complaint data can reveal relations between events that otherwise remain obscured, such as incidents that trigger as well as follow AEs, introducing event cascades, regardless of whether clinical relations seem present.@en

Objective: To assess formats for surgical morbidity and mortality conferences (M&M) for strengths and challenges. Design: A mixed methods approach with local observations to assess key domains of M&M practice (i.e., goals, structure, and process/content) and surveys to assess participants’ expectations and experiences. Setting: Surgical departments of two teaching hospitals (Boston, USA and Leiden, Netherlands). Participants: Participants of surgical M&M, including attending surgeons, residents, physician assistants, and medical students (total n = 135). Results: Surgical M&M practices at both hospitals had education as its overarching goal, but varied in structure and process/content. Expectations were similar at both sites with ≥80% of participants (n = 90; 67% response) expecting M&M to be focused on education as well as quality improvement (QI), blame-free, mandatory for both residents and attendings, and to lead to changes in clinical practice. However, compared to expectations, significantly fewer participants at both sites experienced: a QI focus (both p < 0.001); mandatory faculty attendance (p = 0.004; p < 0.001) and changes to practice (both p < 0.001). In comparison, at the site where an active moderator and QI committee are present, respondents seemed more positive about experiencing a QI focus (73% vs 30%) and changes to practice (44% vs 16%). Conclusion: Despite variation in M&M practice, the same (unmet) expectations existed at both hospitals, indicating that certain challenges may be more universal. M&M was reported to be well-focused on education, and certain aspects (e.g., active moderator and QI committee) seemed beneficial, but expectations were not met for the conference's focus and function for QI. Greater exchange of “best practices” for M&M may enhance the conference's value for improving surgical care.@en

Objectives To explore barriers and facilitators to successful morbidity and mortality conferences (M&M), driving learning and improvement. Design This is a qualitative study with semistructured interviews. Inductive, thematic content analysis was used to identify barriers and facilitators, which were structured across a pre-existing framework for change in healthcare. Setting Dutch academic surgical department with a long tradition of M&M. Participants An interview sample of surgeons, residents and physician assistants (n=12). Results A total of 57 barriers and facilitators to successful M&M, covering 18 themes, varying from case type' to leadership', were perceived by surgical staff. While some factors related to M&M organisation, others concerned individual or social aspects. Eight factors, of which four were at the social level, had simultaneous positive and negative effects (eg, hierarchy' and team spirit'). Mediating pathways for M&M success were found to relate to available information, staff motivation and realisation processes. Conclusions This study provides leads for improvement of M&M practice, as well as for further research on key elements of successful M&M. Various factors were perceived to affect M&M success, of which many were individual and social rather than organisational factors, affecting information and realisation processes but also staff motivation. Based on these findings, practical recommendations were formulated to guide efforts towards best practices for M&M.@en
