RESUMEN

BACKGROUND: Many patients report moderate to severe pain in the acute postoperative period. Enhanced recovery protocols recommend multimodal analgesics, but the optimal combination of these is unknown. PURPOSE: The aim of this study was to synthesize the best available evidence about effectiveness of multimodal analgesics on pain after adult cardiac surgery. METHODS: A systematic review to determine the effect of multimodal postoperative analgesics is proposed (International Prospective Register of Systematic Reviews Registration CRD42022355834). Multiple databases including the Cochrane Library, Cochrane Central Register of Controlled Trials, Cumulative Index to Nursing and Allied Health Literature, American Psychological Association, the Education Resources Information Centre, the Excerpta Medica database, the Medical Literature Analysis and Retrieval System Online, Scopus, Web of Science, and clinical trials databases will be searched. Screening in Covidence and quality assessment will be conducted by 2 authors. A grading of recommendations, assessment, development, and evaluation summary of findings will be presented if meta-analysis is possible.

RESUMEN

Stroke is a complication that can occur in patients who have undergone cardiac surgery and can lead to life-threatening consequences. The causes of post-operative stroke following cardiac surgery are varied, and it is essential to identify patients who are at risk to support early recognition and effective management. Nurses caring for patients following cardiac surgery should understand the causes of stroke, risk factors, preventive measures, early recognition and treatment. A multidisciplinary approach is crucial in ensuring effective therapeutic interventions and optimising outcomes for patients who have experienced stroke following cardiac surgery.

RESUMEN

Despite recent technological advances in the field of surgery, neurological complications remain a significant post-operative issue. Two of the most common post-operative complications are delirium and post-operative cognitive decline, which occur frequently after cardiac surgery. This article provides an overview of delirium and post-operative cognitive decline, including risk factors, signs and symptoms, and diagnosis. The author also considers the nurse's role in managing patients who are at risk of, or have experienced, delirium or post-operative cognitive decline after cardiac surgery.

RESUMEN

BACKGROUND: Postoperative morbidity places considerable burden on health and resources. Thus, strategies to identify, predict, and reduce postoperative morbidity are needed. AIMS: To identify and explore existing preoperative risk assessment tools for morbidity after cardiac surgery. METHODS: Electronic databases (including MEDLINE, CINAHL, and Embase) were searched to December 2020 for preoperative risk assessment models for morbidity after adult cardiac surgery. Models exploring one isolated postoperative morbidity and those in patients having heart transplantation or congenital surgery were excluded. Data extraction and quality assessments were undertaken by two authors. RESULTS: From 2251 identified papers, 22 models were found. The majority (54.5%) were developed in the USA or Canada, defined morbidity outcome within the in-hospital period (90.9%), and focused on major morbidity. Considerable variation in morbidity definition was identified, with morbidity incidence between 4.3% and 52%. The majority (45.5%) defined morbidity and mortality separately but combined them to develop one model, while seven studies (33.3%) constructed a morbidity-specific model. Models contained between 5 and 50 variables. Commonly included variables were age, emergency surgery, left ventricular dysfunction, and reoperation/previous cardiac surgery, although definition differences across studies were observed. All models demonstrated at least reasonable discriminatory power [area under the receiver operating curve (0.61-0.82)]. CONCLUSION: Despite the methodological heterogeneity across models, all demonstrated at least reasonable discriminatory power and could be implemented depending on local preferences. Future strategies to identify, predict, and reduce morbidity after cardiac surgery should consider the ageing population and those with minor and/or multiple complex morbidities.

RESUMEN

OBJECTIVES: Photo at Discharge (PaD) is a nurse-led discharge strategy for enhanced wound care information for patients and healthcare providers. The purpose of this study is to describe implementation of PaD in three English cardiac centres. METHODS: A prospective, cross-sectional design was used to evaluate implementation fidelity and sustainability of PaD on various geographical settings. RESULTS: Three out of four hospitals (75%) approached agreed to complete surveys on implementation fidelity. Implementing the IT component took an average of 16 months (range 11-21 months). Across the three sites, 474 nursing staff have received training on PaD. Since implementing, a combined total of 9007 patients have received PaD. A 1-month compliance snapshot indicated mean of 96% (range 92-100%). CONCLUSIONS: PaD requires collaborative working, a change in behaviour and a change to the service. Despite these challenges, fidelity and sustainability scores across the sites were high. The findings from this study may help to increase implementation quality and dissemination of PaD.

RESUMEN

OBJECTIVES: The objective of this study was to develop and validate a new risk tool (Barts Surgical Infection Risk (B-SIR)) to predict surgical site infection (SSI) risk after all types of adult cardiac surgery, and compare its predictive ability against existing (but procedure-specific) tools: Brompton-Harefield Infection Score (BHIS), Australian Clinical Risk Index (ACRI), National Nosocomial Infection Surveillance (NNIS). STUDY DESIGN AND SETTING: Single-center retrospective analysis of prospectively collected data including 2,449 patients undergoing cardiac surgery between January 2016 and December 2017 in a European tertiary hospital. Thirty-four variables associated with SSI risk after cardiac surgery were collated from three local databases. Independent predictors were identified using stepwise multivariable logistic regression. Bootstrap resampling was conducted to validate the model. Hosmer-Lemeshow goodness-of-fit test was performed to assess calibration of scores. RESULTS: The B-SIR model was constructed from six independent predictors female gender, body mass index >30, diabetes, left ventricular ejection fraction <45%, peripheral vascular disease and operation type, and the risk estimates were derived. The receiver operating characteristics curve for B-SIR was 0.682, vs. 0.603 for BHIS, 0.618 for ACRI, and 0.482 for the NNIS tool. CONCLUSION: B-SIR provides greater predictive power of SSI risk after cardiac surgery compared with existing tools in our population.

RESUMEN

OBJECTIVES: The authors aimed to adapt a practice advisory for the prevention of atrial fibrillation after cardiac surgery (AFACS) recently published in this journal into the authors' local perioperative protocols, implementing the recommendations, with a focus on early postoperative (re)introduction of ß-blockers and overcoming frequent guideline implementation barriers. DESIGN: Development of a prevention care bundle and repeated audit after a model of improvement approach with retrospective analysis. SETTING: Single center (tertiary academic hospital). PARTICIPANTS: A total of 384 patients in 2 cohorts of consecutive patients undergoing open cardiac surgery before and after hospital-wide implementation of a care bundle. INTERVENTIONS: After auditing the standard of care in the authors' center, an AFACS prevention care bundle was designed and implemented, consisting of a graphic tool with 5 pillars based on current evidence for the early postoperative phase. Multidisciplinary teaching and training of staff were delivered, and a second audit was conducted after the implementation period. MEASUREMENTS AND MAIN RESULTS: Significantly more patients received postoperative ß-blockers after care bundle implementation (82.7% pre- v 91.3% post-bundle, p = 0.019), with a higher proportion on day 1 (36.7% pre- v 67% post-bundle, p < 0.001), indicating a successful uptake. The incidence of AFACS was significantly reduced from 35.4% to 23.3% (p = 0.009), with a particularly marked reduction in the age group 65- to 75- years and for isolated aortic valve and coronary artery bypass graft surgery. CONCLUSION: An AFACS prevention care bundle improved adherence to current guidelines with regard to early ß-blocker administration and significantly reduced the incidence of atrial fibrillation after cardiac surgery.
