Down Syndrome and Postoperative Complications in Children Undergoing Intestinal Operations

Down Syndrome: A Review of Key Perioperative Implications

Down syndrome (DS) is the most common chromosomal abnormality in humans that is compatible with life. This syndrome occurs when there is an extra copy of the 21st chromosome. Down syndrome is associated with numerous comorbidities that can pose challenges for the perioperative nurse caring for a patient with DS undergoing surgery. These challenges can affect the patient assessment, communication with the patient, and patient safety (eg, preventing complications). As the life expectancy of people with DS has increased, so too have the chances that perioperative nurses will care for a patient with this disorder. This article reviews the pathophysiology of DS, discusses common comorbidities that may directly affect perioperative care, and reviews an exemplar case study that demonstrates how personnel with knowledge of DS can positively influence surgical team decision making for these patients in the perioperative setting.

Exploring patient safety outcomes for people with learning disabilities in acute hospital settings: a scoping review

OBJECTIVES

To produce a narrative synthesis of published academic and grey literature focusing on patient safety outcomes for people with learning disabilities in an acute hospital setting.

DESIGN

Scoping review with narrative synthesis.

METHODS

The review followed the six stages of the Arksey and O'Malley framework. We searched four research databases from January 2000 to March 2021, in addition to handsearching and backwards searching using terms relating to our eligibility criteria-patient safety and adverse events, learning disability and hospital setting. Following stakeholder input, we searched grey literature databases and specific websites of known organisations until March 2020. Potentially relevant articles and grey literature materials were screened against the eligibility criteria. Findings were extracted and collated in data charting forms.

RESULTS

45 academic articles and 33 grey literature materials were included, and we organised the findings around six concepts: (1) adverse events, patient safety and quality of care; (2) maternal and infant outcomes; (3) postoperative outcomes; (4) role of family and carers; (5) understanding needs in hospital and (6) supporting initiatives, recommendations and good practice examples. The findings suggest inequalities and inequities for a range of specific patient safety outcomes including adverse events, quality of care, maternal and infant outcomes and postoperative outcomes, in addition to potential protective factors, such as the roles of family and carers and the extent to which health professionals are able to understand the needs of people with learning disabilities.

CONCLUSION

People with learning disabilities appear to experience poorer patient safety outcomes in hospital. The involvement of family and carers, and understanding and effectively meeting the needs of people with learning disabilities may play a protective role. Promising interventions and examples of good practice exist, however many of these have not been implemented consistently and warrant further robust evaluation.

Pneumonia and respiratory infections in Down syndrome: A scoping review of the literature

Pneumonia and respiratory infections impact infants and children with Down syndrome; pneumonia is a leading cause of mortality in adults with Down syndrome. We aimed to review the literature to evaluate gaps and address key questions. A series of key questions were formulated a priori to inform the search strategy and review process; addressed prevalence, severity, etiology, risk factors, preventive methods, screening, and financial costs, potential benefits or harms of screening. Using the National Library of Medicine database, PubMed, detailed literature searches on pneumonia and respiratory infections in Down syndrome were performed. Previously identified review articles were also assessed. The quality of available evidence was then evaluated and knowledge gaps were identified. Forty-two relevant original articles were identified which addressed at least one key question. Study details including research design, internal validity, external validity, and relevant results are presented. Pneumonia and respiratory infections are more prevalent and more severe in individuals with Down syndrome compared to healthy controls through literature review, yet there are gaps in the literature regarding the etiology of pneumonia, the infectious organism, risk factors for infection, and to guide options for prevention and screening. There is urgent need for additional research studies in Down syndrome, especially in the time of the current COVID-19 pandemic.

Clinical implications of immune-mediated diseases in children with Down syndrome

Children with Down syndrome have changes in their innate and adaptive immunity, which contribute to increased rates of infections, autoimmune diseases, and haematological malignancies. While improved care for congenital heart disease has decreased mortality and morbidity, complications related to immune-mediated diseases continue to limit the life expectancy in Down syndrome. Infectious diseases are common and have a significant effect on development, behaviour and quality of life. Infection frequency and severity are influenced by various anatomical and physiological alterations in addition to immunological changes in Down syndrome. Thus, prevention of respiratory tract infections requires a multifactorial approach. This could include additional active and/or passive immunizations, prophylactic antibiotics, immunoglobulin replacement and ear, nose and throat surgical interventions. Autoimmune conditions like coeliac disease, type I diabetes mellitus and thyroid disease are classically mentioned in the context of Down syndrome. However, autoinflammatory conditions are more prevalent as well. Screening for autoimmune diseases is required and immunosuppression has to be used with caution. Future studies should address optimal screening programmes for immune-mediated diseases in individuals with Down syndrome, as well as the effect of immune modulation, to further decrease morbidity and mortality, and improve the quality of life of individuals with Down syndrome.

Effect of Trisomy 21 on Postoperative Length of Stay and Non-cardiac Surgery After Complete Repair of Tetralogy of Fallot

Trisomy 21 (T21) is the most common chromosomal abnormality, and is frequently associated with congenital heart disease. Results of previous studies evaluating the effect of T21 on postoperative outcomes and complications following heart surgery have been mixed. Our goal was to determine if T21 is associated with higher frequency of adverse postoperative outcomes following repair of tetralogy of Fallot (TOF). A query of the Pediatric Health Information System was performed for patients who underwent complete repair of TOF from 2004 to 2015. Patients with a genetic syndrome other than T21 and tracheostomy and/or gastrostomy prior to heart surgery were excluded. Two groups were created on the basis of whether patients received a diagnostic code for T21. The adverse outcomes of interest were postoperative mortality, postoperative length of stay (LOS), postoperative gastrostomy, and postoperative tracheostomy. Univariate and Kaplan-Meier analysis were performed to evaluate outcomes. There were a total of 4790 patients; 430 (9%) patients had T21, and 4360 (91%) patients without a genetic diagnosis. There was no significant difference in mortality before discharge between those with and without T21 (2.3% vs 1.4%; p = 0.155). Patients with T21 had longer postoperative LOS (mean of 19.8 days vs 12.4 days; p < 0.001), and higher rates of postoperative gastrostomy (13.3% vs 5.3%; p < 0.02). There was no significant difference between groups for rates of postoperative tracheostomy (1.9% vs 1.2%; p = 0.276). Kaplan-Meier analysis confirmed that patients with T21 had longer postoperative LOS and greater incidence of gastrostomy.
