The impact of intestinal stoma formation on patient quality of life after emergency surgery-A systematic review.

AIM: Elective stoma formation has a negative effect on patient quality of life (QoL), with a potential detrimental impact on body image, confidence and social functioning being shown previously. However, the impact of emergency stoma formation on QoL has been explored less frequently. This systematic review aims to synthesize all available literature exploring QoL via patient-reported outcome measures. METHODS: A search strategy was implemented on 24 November 2022 across Embase, MEDLINE, PsycInfo and the Cochrane Library database after registration on PROSPERO (CRD42022370606). Studies were included if they used a standardized patient-reported outcome measure, had more than five emergency stoma patients, age > 18 years and were fully published in English. Two of three independent researchers screened articles, extracted data and performed quality assessment using the Newcastle-Ottawa Scale and the Cochrane risk of bias tool. RESULTS: In all, 1775 articles were screened, with 16 included in the systematic review. This included 1868 emergency stoma patients (men:women 0.53; median age 64.6 years) followed up for a median of 12 months. Patients who had a Hartmann's procedure for perforated diverticulitis had poorer QoL than those who underwent primary anastomosis. There was a negligible difference in QoL between those who had a colonic stent for obstructing colorectal cancer compared with those who underwent emergency stoma formation. Female sex, end stoma formation and ileostomy formation were all identified as risk factors for poorer QoL. CONCLUSION: Patients undergoing emergency stoma surgery have marginally poorer QoL compared with those undergoing similar procedures without stoma formation. Further work is required to identify risk factors associated with this and also to compare QoL after stoma reversal.

A Systematic Review of the Abdominal Surgeon's Personality: Exploring Common Traits in Western Populations.

The personality traits commonly seen in abdominal surgeons remains undefined, and its potential influence on decision-making and patient outcomes underexplored. This systematic review identified studies on abdominal surgeons who had undergone validated personality testing, with assessment of decision-making and post-operative patient outcomes. The study protocol was registered on PROSPERO (University of York, UK (CRD42019151375)). MEDLINE, Embase, PsycInfo and Cochrane Library databases were searched using the keywords: surgeon; surgeon personality; outcomes. All study designs were accepted including adult visceral surgeons published in English. Five articles from 3056 abstracts met our inclusion criteria and one article was identified from hand searches with two reviewers screening studies. Bias was assessed using the Newcastle-Ottawa scale. Six studies included 386 surgeons. Studies assessing personality using the Five Factor Model (four studies, 329 surgeons) demonstrated higher levels of conscientiousness (self-discipline, thoughtfulness), extraversion (sociability, emotional expression) and openness (creative, conventional) in surgeons versus population norms. Surgeon characterisation of agreeableness and emotional stability was less clear, with studies reporting mixed results. Post-operative outcomes were reported by only one study. Further exploration of the influence of surgeon personality and its influence on decision-making is necessary to deliver patient-centred care and targeted non-technical skills training for surgeons.

The hallmarks of childhood abuse and neglect: A systematic review.

BACKGROUND: Studies on the impacts of child maltreatment (CM) have been conducted in diverse areas. Mechanistic understanding of the complex interplay between factors is lacking. Hallmarking is an approach which identifies common factors across studies and highlights the most robust findings. OBJECTIVES: In a review of systematic reviews and meta-analyses, we addressed the following questions: 1) What are the hallmarks associated with exposure to CM across the bio-ecological spectrum? 2) What is the strength of evidence to support each hallmark? 3) What are the gaps that future research should address? METHODS: A comprehensive literature search was carried out to find relevant systematic reviews or meta-analyses. 269 articles were read in full and 178 articles, encompassing more than 6000 original papers, were included in the final synthesis. All reviews were independently rated for quality by at least 2 reviewers using AMSTAR-2. RESULTS: Of 178 review articles, 6 were rated as high quality (all meta-analyses) and 46 were rated as medium quality. Most were from high income countries. CONCLUSIONS: Based on the most commonly reported high-quality research findings we propose that the hallmarks of exposure to child maltreatment are: Increased risk of psychopathology; Increased risk of obesity; Increased risk of high- risk sexual behaviours, Increased risk of smoking; and Increased risk of child maltreatment in children with disabilities. Research gaps include a lack of focus on complexity and resilience. Little can be concluded about directions of causality or mechanisms. Adequately powered prospective studies are required to move the field forward.

Systematic review protocol examining the influence of surgeon personality on perioperative decision making in abdominal surgery.

INTRODUCTION: There is limited published literature exploring how the personality traits of surgeons may influence preoperative decision making, particularly in the context of visceral/abdominal surgery. Multiple validated personality scoring systems exist and have been used to describe surgeon personalities previously. The degree to which each trait is expressed by abdominal surgeons is neither currently known, nor the impact of these traits on postoperative outcomes. The protocol has been written in line with the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols checklist. METHODS AND ANALYSIS: The search strategy has been developed by a Health Scientist Librarian in collaboration with the review team. The search was conducted on 1st October 2019.Database subject headings and text words relating to 'abdominal/general surgeons', 'personality', 'postoperative outcomes' and 'decision making' formed the basis of our literature search strategy; the MEDLINE, EMBASE, PsycInfo and Cochrane databases will be searched. Three reviewers will independently screen and appraise articles, with a fourth reviewer utilised if disagreements arise.A systematic narrative synthesis will be performed, with information presented in text and table format. These will summarise the findings and characteristics of any included studies. Using guidance from the Centre for Reviews and Dissemination, the reviewers will describe the potential relationship and findings between studies using the narrative synthesis. Studies will only be reported if they are felt to have low or mid-levels of bias. Studies felt to display high levels of bias will be excluded. ETHICS AND DISSEMINATION: This study does not require ethical approval. The formal systematic review will be submitted for peer reviewed publication and presented at relevant conferences. The methods may inform future reviews in other surgical specialties regarding surgeon personality. PROSPERO REGISTRATION NUMBER: CRD42019151375.
