Reporting of health-related quality of life in emergency laparotomy trials: a systematic review and narrative synthesis

Purpose Emergency laparotomy is associated with high morbidity for the surgical patient. Understanding patients’ health-related quality of life after their surgery is important to enhance the informed consent process, and to enable the evaluation and improvement of surgical care. This review aims to summarise the use of health-related quality of life tools in clinical trials involving patients undergoing emergency laparotomy. Methods A systematic review was undertaken of the scientific literature published in the MEDLINE® and PubMed databases between January 2011 and July 2021. A narrative synthesis approach was chosen to synthesise the diverse range of studies in a structured manner. All included papers were evaluated using the Cochrane Collaboration’s tool for assessing risk of bias. Results Eleven studies were selected for inclusion. Most of the studies had a low risk of bias. Two of the studies used health-related quality of life as the primary outcome measure. A variety of health-related quality of life measurement tools were used; the EQ-5D tool was the most popular questionnaire. Protocol adherence was dependent on the length of time which had elapsed after emergency surgery. Conclusion There are many perceived challenges to collecting health-related quality of life data in the emergency surgery setting. Many of these can be offset with progressive trial designs. There is a need for further research in the systematic development of patient-reported outcomes for use in emergency surgery

Impact of in-hospital postoperative complications on quality of life up to 12 months after major abdominal surgery

Background Postoperative complications are common, but there are limited data regarding their implications on patients’ quality of life. This study aimed to address this gap in the literature by analysing the impact of postoperative complications on patients’ health-related quality of life. Methods Data from the Perioperative Quality Improvement Programme were analysed, and included patient-level data for 19 685 adults who underwent elective major abdominal procedures in England since 2016. Postoperative complications were graded using the Clavien–Dindo classification. Quality of life was assessed by responses to the EuroQol five-dimension five-levels-of-response (EQ-5D-5L™) questionnaire before surgery, and at 6 and 12 months after operation. Ordinal logistic regression was used to estimate the association between Clavien–Dindo grades and quality of life. Tobit and ordinary least squares regression analyses were used to estimate the quality-adjusted life-year (QALY) loss resulting from postoperative complications between admission and 12 months after surgery. Results At 6 and 12 months after surgery, increasingly severe postoperative complications were significantly associated with poorer health-related quality of life. The effect of postoperative complications on quality of life was sustained until at least 12 months after operation. Between admission and 12 months after surgery, 0.012, 0.026, 0.033, and 0.086 QALYs were lost for those experiencing a grade I, II, III, or IV postoperative complication respectively. Conclusion Postoperative complications have a significant and sustained effect on patients’ quality of life after surgery; this effect worsens as the severity of the complications increases

Clinical applications of contactless photoplethysmography for monitoring in adults: A systematic review and meta-analysis

Contactless photoplethysmography (cPPG) is a method of physiological monitoring. It differs from conventional monitoring methods (e.g., saturation probe) by ensuring no contact with the subject by use of a camera. The majority of research on cPPG is conducted in a laboratory setting or in healthy populations. This review aims to evaluate the current literature on monitoring using cPPG in adults within a clinical setting. Adhering to the Preferred Items for Systematic Reviews and Meta-analysis (PRISMA, 2020) guidelines, OVID, Webofscience, Cochrane library, and clinicaltrials.org were systematically searched by two researchers. Research articles using cPPG for monitoring purposes in adults within a clinical setting were selected. Twelve studies with a total of 654 individuals were included. Heart rate (HR) was the most investigated vital sign (n = 8) followed by respiratory rate ((n = 2), Sp02 (n = 2), and HR variability (n = 2). Four studies were included in a meta-analysis of HR compared to ECG data which demonstrated a mean bias of –0.13 (95% CI, –1.22–0.96). This study demonstrates cPPG can be a useful tool in the remote monitoring of patients and has demonstrated accuracy for HR. However, further research is needed into the clinical applications of this method

Assessment of stability and fluctuations of cultured lower airway bacterial communities in people with cystic fibrosis

Background: Routine clinical culture detects a subset of the cystic fibrosis (CF) airways microbiota based on culture-independent (molecular) methods. This study aimed to determine how extended sputum culture of viable bacteria changes over time in relation to clinical status and predicts exacerbations. Methods: Sputa from patients at a baseline stable and up to three subsequent time-points were analysed by extended-quantitative culture; aerobe/anaerobe densities, ecological indexes and community structure were assessed together with clinical outcomes. Results: Eighty patients were prospectively recruited. Sputa were successfully collected and cultured at 199/267 (74.5%) study visits. Eighty-two sputa from 25 patients comprised a complete sample-set for longitudinal analyses. Bacterial density, ecological indexes and clinical outcomes were unchanged in 18 patients with three sequential stable visits. Conversely, in 7 patients who had an exacerbation, total bacterial and aerobe densities differed over four study visits (P < .001) with this difference particularly apparent between the baseline visit and completion of acute antibiotic treatment where a decrease in density was observed. Bacterial communities were more similar within than between patients but stable patients had the least variation in community structure over time. Using logistic regression in a further analysis, baseline features in 37 patients without compared to 15 patients with a subsequent exacerbation showed that clinical measures rather than bacterial density or ecological indexes were independent predictors of an exacerbation. Conclusions: Greater fluctuation in the viable bacterial community during treatment of an exacerbation than between stable visits was observed. Extended-quantitative culture did not provide prognostic information of a future exacerbation

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

Thoracic ultrasound for pleural effusion: delays and cost associated with departmental scanning.

SummaryPleural effusion is a common clinical condition on medical wards and the majority of cases undergo pleural aspiration or chest drain insertion as a diagnostic or therapeutic procedure. The use of a thoracic ultrasound scan (USS) improves diagnostic yield for pleural fluid aspiration and reduces complications and USS is increasingly recommended prior to all pleural aspirations or drains and ‘real time’ scanning which, as well as potentially reducing delays, enhances the safety of the procedure. In many U.K hospitals a thoracic USS is still routinely performed in the radiology department. We reviewed radiology records and case notes from hospital in-patients to assess potential delays and associated costs with departmental thoracic USS and to identify cases where physician-led portable USS would potentially have improved the patient's journey.We demonstrated delays resulting in significant financial costs to the hospital of an estimated £17, 880 per annum. However, the cost to the patient is also significant, both in terms of patient experience (many of whom will have an underlying diagnosis of metastatic carcinoma and with a limited life expectancy) but also patient safety. Respiratory physicians are increasingly recognising the importance of portable thoracic USS to guide pleural procedures and there has been increasing use of physician-led portable thoracic USS. Hospitals should be encouraged to fund both portable thoracic USS equipment but it is also crucial that training in this area is properly supported
