Meta-Analysis Review
STUDY OBJECTIVE
To evaluate all available evidence thus far on opioid based versus opioid-free anesthesia and its effect on acute and chronic postoperative pain.
DESIGN
Systematic review and meta-analysis of randomized clinical trials.
SETTING
Operating room, postoperative recovery room and ward.
PATIENTS
Patients undergoing general anesthesia.
INTERVENTIONS
After consulting MEDLINE, EMBASE and Cochrane database, studies which compared opioid free anesthesia (OFA) with opioid based anesthesia (OBA) were included (last search April 15th 2022).
MEASUREMENTS
Primary outcomes were acute and chronic pain scores in NRS or VAS. Secondary outcomes were quality of recovery and postoperative opioid consumption. Risk of bias was assessed using the RoB2 tool and a random effects model for the meta-analysis was conducted.
MAIN RESULTS
We identified 1245 citations, of which 38 studies met our inclusion criteria. There is moderate quality evidence showing no clinically relevant difference of Numeric Rating Scale (NRS) scores or opioid consumption in the postoperative period (pooled mean difference of 0.39 points with a CI of 0.19-0.59 and 4.02 MME with a CI of 1.73-6.30). We found only one small-sized study reporting no effect of opioid-free anesthesia on chronic pain. The quality of recovery was superior in patients with opioid-free anesthesia (mean difference of 8.26 points), however, this pooled analysis was comprised of only two studies. Postoperative nausea and vomiting (PONV) occurred less in opioid-free anesthesia, but bradycardia was more frequent.
CONCLUSIONS
We concluded that we cannot recommend one strategy over the other. Future studies could focus on quality of recovery as outcome measure and adequately powered studies on the effects of opioid-free anesthesia on chronic pain are eagerly awaited.

Meta-Analysis
BACKGROUND
The systematic review is aimed to evaluate the cost-effectiveness of minimally invasive surgery (MIS) and open distal pancreatectomy and pancreaticoduodenectomy.
METHOD
The MEDLINE, CENTRAL, EMBASE, Centre for Reviews and Dissemination, and clinical trial registries were systematically searched using the PRISMA framework. Studies of adults aged ≥ 18 year comparing laparoscopic and/or robotic versus open DP and/or PD that reported cost of operation or index admission, and cost-effectiveness outcomes were included. The risk of bias of non-randomised studies was assessed using the Newcastle-Ottawa Scale, while the Cochrane Risk of Bias 2 (RoB2) tool was used for randomised studies. Standardised mean differences (SMDs) with 95% confidence intervals (CI) were calculated for continuous variables.
RESULTS
Twenty-two studies (152,651 patients) were included in the systematic review and 15 studies in the meta-analysis (3 RCTs; 3 case-controlled; 9 retrospective studies). Of these, 1845 patients underwent MIS (1686 laparoscopic and 159 robotic) and 150,806 patients open surgery. The cost of surgical procedure (SMD 0.89; 95% CI 0.35 to 1.43; I = 91%; P = 0.001), equipment (SMD 3.73; 95% CI 1.55 to 5.91; I = 98%; P = 0.0008), and operating room occupation (SMD 1.17, 95% CI 0.11 to 2.24; I = 95%; P = 0.03) was higher with MIS. However, overall index hospitalisation costs trended lower with MIS (SMD - 0.13; 95% CI - 0.35 to 0.06; I = 80%; P = 0.17). There was significant heterogeneity among the studies.
CONCLUSION
Minimally invasive major pancreatic surgery entailed higher intraoperative but similar overall index hospitalisation costs.

Review
BACKGROUND
Organizational factors may influence surgical outcomes, regardless of extensively studied factors such as patient preoperative risk and surgical complexity. This study was designed to explore how operating room organization determines surgical performance and to identify gaps in the literature that necessitate further investigation.
METHODS
We conducted a systematic review according to PRISMA guidelines to identify original studies in Pubmed and Scopus from January 1, 2000 to December 31, 2019. Studies evaluating the association between five determinants (team composition, stability, teamwork, work scheduling, disturbing elements) and three outcomes (operative time, patient safety, costs) were included. Methodology was assessed based on criteria such as multicentric investigation, accurate population description, and study design.
RESULTS
Out of 2625 studies, 76 met inclusion criteria. Of these, 34 (44.7%) investigated surgical team composition, 15 (19.7%) team stability, 11 (14.5%) teamwork, 9 (11.8%) scheduling, and 7 (9.2%) examined the occurrence of disturbing elements in the operating room. The participation of surgical residents appeared to impact patient outcomes. Employing specialized and stable teams in dedicated operating rooms showed improvements in outcomes. Optimization of teamwork reduced operative time, while poor teamwork increased morbidity and costs. Disturbances and communication failures in the operating room negatively affected operative time and surgical safety.
CONCLUSION
While limited, existing scientific evidence suggests that operating room staffing and environment significantly influences patient outcomes. Prioritizing further research on these organizational drivers is key to enhancing surgical performance.

Review
This systematic review examines the recent use of artificial intelligence, particularly machine learning, in the management of operating rooms. A total of 22 selected studies from February 2019 to September 2023 are analyzed. The review emphasizes the significant impact of AI on predicting surgical case durations, optimizing post-anesthesia care unit resource allocation, and detecting surgical case cancellations. Machine learning algorithms such as XGBoost, random forest, and neural networks have demonstrated their effectiveness in improving prediction accuracy and resource utilization. However, challenges such as data access and privacy concerns are acknowledged. The review highlights the evolving nature of artificial intelligence in perioperative medicine research and the need for continued innovation to harness artificial intelligence's transformative potential for healthcare administrators, practitioners, and patients. Ultimately, artificial intelligence integration in operative room management promises to enhance healthcare efficiency and patient outcomes.

Review
INTRODUCTION
The integration of high-resolution video into surgical practice has fostered widespread interest in capturing surgical video recordings for the purposes of patient care, medical training, quality improvement, and documentation. The capture, analysis, and storing of such recordings inherently impact operating room (OR) activities and introduce potential harms to patients as well as members of the surgical team, which can be analyzed from both ethical and legal perspectives.
METHODS
Following Preferred Reporting Items for Systematic Reviews and Meta Analyses (PRISMA) guidelines, a systematic literature search of PubMed was conducted. The citations of included articles were then reviewed to find any articles not captured by our initial search.
RESULTS
62 Articles were included in the review (52 from PubMed search and 10 from citation review). Prevalent key issues in the literature at present include privacy, consent, ownership, legal use and discoverability, editing, data security, and recording's impact on the surgical team.
CONCLUSIONS
This review aims to spark proactive discussions of the ethical and legal implications of recording in the OR, which will guide transformation as the medical field adapts to new and innovative technologies without compromising its ideals or patient care.

Review
INTRODUCTION
Environmental factors in the operating room during cesarean sections are likely important for both women/birthing people and their babies but there is currently a lack of rigorous literature about their evaluation. The principal aim of this study was to systematically examine studies published on the physical environment in the obstetrical operating room during c-sections and its impact on mother and neonate outcomes. The secondary objective was to identify the sensors used to investigate the operating room environment during cesarean sections.
METHODS
In this literature review, we searched MEDLINE a database using the following keywords: Cesarean section AND (operating room environment OR Noise OR Music OR Video recording OR Light level OR Gentle OR Temperature OR Motion Data). Eligible studies had to be published in English or French within the past 10 years and had to investigate the operating room environment during cesarean sections in women. For each study we reported which aspects of the physical environment were investigated in the OR (i.e., noise, music, movement, light or temperature) and the involved sensors.
RESULTS
Of a total of 105 studies screened, we selected 8 articles from title and abstract in PubMed. This small number shows that the field is poorly investigated. The most evaluated environment factors to date are operating room noise and temperature, and the presence of music. Few studies used advanced sensors in the operating room to evaluate environmental factors in a more nuanced and complete way. Two studies concern the sound level, four concern music, one concerns temperature and one analyzed the number of entrances/exits into the OR. No study analyzed light level or more fine-grained movement data.
CONCLUSIONS
Main findings include increase of noise and motion at specific time-points, for example during delivery or anaesthesia; the positive impact of music on parents and staff alike; and that a warmer theatre is better for babies but more uncomfortable for surgeons.

Meta-Analysis
STUDY OBJECTIVE
This meta-analysis aimed at identifying the risk factors for and their strengths in predicting difficult mask ventilation (MV) through a systematic approach.
DESIGN
Meta-analysis of observational studies.
SETTING
Operating room.
INTERVENTION
Airway- or patient-related risk factors for difficult MV reported in over 20% of eligible studies identified through literature review.
PATIENTS
Adults receiving anesthetic induction with requirement of MV.
MEASUREMENTS
Databases including EMBASE, MEDLINE, Google Scholar, and Cochrane Library were searched from inception to July 2022. The primary outcomes were the identification of commonly reported risk factors for MV and a comparison of their strengths in difficult MV prediction, while the secondary outcomes were the prevalence of difficult MV in the general population and those with obesity.
MAIN RESULTS
Meta-analysis of 20 observational studies involving 335,846 patients identified 13 risk factors with predictive strengths (all p < 0.05): neck radiation (OR = 5.0, five studies, n = 277,843), increased neck circumference (OR = 4.04, 11 studies, n = 247,871), obstructive sleep apnea (OSA) (OR = 3.61, 12 studies, n = 331,255), presence of beard (OR = 3.35, 12 studies, n = 295,443), snoring (OR = 3.06, 14 studies, n = 296,105), obesity (OR = 2.99, 11 studies, n = 278,297), male gender (OR = 2.76, 16 studies, n = 320,512), Mallampati score III-IV (OR = 2.36, 17 studies, n = 335,016), limited mouth opening (OR = 2.18, six studies, n = 291,795), edentulous (OR = 2.12, 11 studies, n = 249,821), short thyroid-mental distance (OR = 2.12, six studies, n = 328,311), old age (OR = 2, 11 studies, n = 278,750), and limited neck movement (OR = 1.98, nine studies, n = 155,101). The prevalence of difficult MV was 6.1% (16 studies, n = 334,694) and 14.4% (four studies, n = 1152) in the general population and those with obesity, respectively.
CONCLUSIONS
Our results demonstrated the strengths of 13 most common risk factors for predicting difficult MV, which may serve as an evidence-based reference for clinicians to incorporate into their daily practice.

Review
PURPOSE
The published information on virtual supervision (VS) in ophthalmology is not well described. This scoping review describes the evidence and potential role for VS in ophthalmic practice and education.
METHODS
A literature search strategy was developed in accordance with Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR). We included full-text articles published in an English-language peer-reviewed journal that involved physician-physician or physician-trainee VS in ophthalmology. We excluded studies with direct (in-person) supervision. Two investigators independently extracted from each article the year of publication and study location, design, participant characteristics, sample size, and outcomes. We appraised the methodological quality of the studies using the Mixed Methods Appraisal Tool (MMAT).
RESULTS
Seven articles were included in our qualitative synthesis. Supervisees ranged from physicians such as an ophthalmic surgeon and a general practitioner to medical trainees such as ophthalmology residents, vitreoretinal fellows, and emergency medicine residents. Study settings included emergency departments, operating rooms, eye clinics, and a rural hospital. All studies reported successful transmission of real-time images or videos of clinical examinations and surgical or in-office procedures. Various methods were used to ensure high image and video quality during VS, although some technical challenges remained. MMAT ratings revealed limitations in outcome measurement, statistical analysis, sampling strategy, and inclusion of confounding factors.
CONCLUSION
Virtual supervision in ophthalmology is technologically feasible and permits synchronous communication and transmission of clinical data, which can be used to formulate diagnostic and management plans and learn new surgical skills. Future studies with larger sample sizes and robust study designs should investigate factors that make VS effective in ophthalmic practice and education.

Review
BACKGROUND
Older people in the nursing home environment are much less mobile and capable of taking care of themselves as they age, and most of them face the plight of loneliness, which seriously affects the quality of life of older people in their later years.
AIMS
A systematic review and synthesis of older people's experiences of loneliness in nursing homes.
DESIGN
Following ENTREQ, do a systematic evaluation and synthesis of qualitative investigations.
METHODS
A search of PubMed, Cochrane Library, Web of Science, Embase, the Chinese biomedical literature service system, the China National Knowledge Infrastructure, the Wanfang Database and the Wipu Database for qualitative studies of older people's experiences of loneliness in nursing homes was conducted with a search time frame of March 2023. Evaluation of the quality of the literature using the Joanna Briggs Institute's Australian Centre for Evidence-Based Health Care Quality Assessment Criteria for Qualitative Research, And the data were synthesised using Thomas and Harden's method of thematic and content analysis.
RESULTS
A total of 13 papers were included, and 36 research findings were distilled and integrated into three themes: causes of loneliness; feelings of loneliness; coping with loneliness; and seven sub-themes: aging and loss; environmental transformation; loneliness is a pain; loneliness is a choice; participation; strengthening social ties; and diverting attention.
CONCLUSIONS
Older people in nursing homes face varying degrees of loneliness, which is a subjective feeling influenced by the interplay between personal awareness and the external environment, so future care interventions should be developed in a comprehensive manner, taking into account the characteristics of the older people themselves and their external environment.

Review
BACKGROUND
Hemorrhage control is a time-critical task, and recent studies have demonstrated that a shorter time to definitive care is positively associated with patient survival and functional outcomes. The concept of direct transport to the operating room was proposed in the 1960s to reduce treatment time. Some trauma centers have developed protocols for direct-to-operating room resuscitation (DOR) programs. Moreover, few studies have reported the clinical outcomes of DOR in patients with trauma; however, their clinical effect in improving the efficiency and quality of care remains unclear. In this systematic review, we aimed to consolidate all published studies reporting the effect of DOR on severe trauma and evaluate its utility.
METHODS
The PubMed, EMBASE, and Cochrane databases were searched from inception to April 2023, to identify all articles published in English that reported the effect of direct-to-operating room trauma resuscitation for severe trauma. The articles were reviewed as references of interest.
RESULTS
We reviewed six studies reporting the clinical effect of operating room trauma resuscitation. A total of 3232 patients were identified. Five studies compared the actual mortality with the predicted mortality using the trauma score and injury severity score, while one study compared mortality using propensity matching. Four studies reported that the actual survival rate for overall injuries was better than the predicted survival rate, whereas two studies reported no difference. Some studies performed subgroup analyses. Two studies showed that the survival rate for penetrating injuries was better than the predicted survival rate, and one showed that the survival rate for blunt injuries was better than the predicted survival rate. Five studies reported the time to surgical intervention, which was within 30 min. Two studies time-compared surgical intervention, which was shorter in patients who underwent DOR.
CONCLUSION
Implementing DOR is likely to have a beneficial effect on mortality and can facilitate rapid intervention in patients with severe shock. Future studies, possibly clinical trials, are needed to ensure a proper comparison of the efficiency.
