Paediatric hospital admissions for psychiatric and psychosocial reasons during the first year of the COVID-19 pandemic.

Increases in youth psychiatric presentations to out-patient and emergency department settings during COVID-19 have been reported. This study, using data from five hospitals in Ireland, examines changes in the number and type of paediatric admissions during COVID-19 (March 2020 - February 2021) compared to the previous two years. ICD-10 classification was used to establish admissions with mental, behavioural, neuro-developmental disorders and psychosocial reasons (MBN-PS). Overall hospital admissions fell by 25.3%, while MBN-PS fell by only 2.6%, mostly during an initial lockdown. Admissions for MBN-PS increased in July-August (9.2%), increased further in September-December (28.3%), returning to pre-COVID-19 levels in January-February 2021. Significant increases were observed among youths with anorexia nervosa (47.8%), other eating disorders (42.9%), and admissions for anxiety (29.6%), with these effects relating to females only. Although admissions for self-harm increased (3%) and rates of ASD admissions reduced (17%), these were not statistically significant. The disproportionate increase in admissions for MBN-PS compared to medical admissions suggests an adverse effect of COVID-19 on youth mental health, for females in particular, and supports previous reports of a pandemic specific increase in eating psychopathology. Combined community and acute service delivery and capacity planning are urgently needed given the prior underfunding of services pre-pandemic.

Association between tocilizumab treatment of hyperinflammatory patients with COVID-19 in a critical care setting and elevated incidence of hospital-acquired bacterial and invasive fungal infections.

BACKGROUND: Tocilizumab is an interleukin-6 inhibitor that reduces mortality and the need for invasive mechanical ventilation, while increasing the possibility of successful hospital discharge for hyperinflammatory patients with severe coronavirus disease 2019 (COVID-19). No increase in adverse events or serious infections has been reported previously. AIM: To describe the characteristics and outcomes of patients with severe COVID-19 in critical care who received tocilizumab, and to compare mortality and length of hospital stay for patients who received tocilizumab (N=41) with those who did not (N=33). METHODS: Retrospective review of data related to patients with COVID-19 who received tocilizumab in a critical care setting from 1st January to 31st December 2021. FINDINGS: Amongst COVID-19 survivors, those who had received tocilizumab had longer intensive care unit (ICU) stays (median length 21 vs 9 days) and hospital stays (45 vs 34 days) compared with those who had not received tocilizumab. Thirty-day mortality (29% vs 36%; P=0.5196) and 60-day mortality (37% and 42%; P=0.6138) were not significantly lower in patients who received tocilizumab. Serious bacterial and fungal infections occurred at higher frequency amongst patients who received tocilizumab [odds ratio (OR) 2.67, 95% confidence interval (CI) 1.04-6.86; P=0.042], and at significantly higher frequency than in non-COVID-19 ICU admissions (OR 5.26, 95% CI 3.08-9.00; P<0.0001). CONCLUSIONS: In this single-centre study, patients in critical care with severe COVID-19 who received tocilizumab had a greater number of serious bacterial and fungal infections, but this may not have been a direct effect of tocilizumab treatment.

Healthcare utilisation and unmet health needs in children with intellectual disability: a propensity score matching approach using longitudinal cohort data.

BACKGROUND: Health disparities for children with intellectual disabilities can be challenging to measure due to many other factors that can impact health and healthcare use. The aim of the current study was to use longitudinal cohort data to compare children with intellectual disability (ID) in Ireland between 2006 and 2014 on healthcare utilisation and unmet need, at ages 9 and 13, using a propensity score matching (PSM) approach. METHODS: Using data from the Growing up in Ireland study, PSM was used to identify an appropriate control sample to compare with a sample of children with ID (n = 124). Participants were matched on variables that are known to influence healthcare utilisation to reduce the impact of confounding variables between groups so that differences between the groups can be estimated. Logistic regression was used to estimate effects at ages 9 and 13. RESULTS: Children with ID were no more likely to have visited a general practitioner or emergency department in the past 12 months than children without ID. They did have a greater likelihood of visiting a doctor in a hospital in the past 12 months and of having an overnight stay in hospital by age 9. Primary caregivers of children with ID were more likely to report unmet health needs at ages 9 and 13. CONCLUSIONS: This approach is a novel means of comparing healthcare use in this population by balancing the impact of other factors that may result in inequities, to which children with ID may be more vulnerable.

Defining and assessing context in healthcare implementation studies: a systematic review.

BACKGROUND: The implementation of evidence-based healthcare interventions is challenging, with a 17-year gap identified between the generation of evidence and its implementation in routine practice. Although contextual factors such as culture and leadership are strong influences for successful implementation, context remains poorly understood, with a lack of consensus regarding how it should be defined and captured within research. This study addresses this issue by providing insight into how context is defined and assessed within healthcare implementation science literature and develops a definition to enable effective measurement of context. METHODS: Medline, PsychInfo, CINAHL and EMBASE were searched. Articles were included if studies were empirical and evaluated context during the implementation of a healthcare initiative. These English language articles were published in the previous 10 years and included a definition and assessment of context. Results were synthesised using a narrative approach. RESULTS: Three thousand and twenty-one search records were obtained of which 64 met the eligibility criteria and were included in the review. Studies used a variety of definitions in terms of the level of detail and explanation provided. Some listed contextual factors (n = 19) while others documented sub-elements of a framework that included context (n = 19). The remaining studies provide a rich definition of general context (n = 11) or aspects of context (n = 15). The Alberta Context Tool was the most frequently used quantitative measure (n = 4), while qualitative papers used a range of frameworks to evaluate context. Mixed methods studies used diverse approaches; some used frameworks to inform the methods chosen while others used quantitative measures to inform qualitative data collection. Most studies (n = 50) applied the chosen measure to all aspects of study design with a majority analysing context at an individual level (n = 29). CONCLUSIONS: This review highlighted inconsistencies in defining and measuring context which emphasised the need to develop an operational definition. By providing this consensus, improvements in implementation processes may result, as a common understanding will help researchers to appropriately account for context in research.

Factors that influence family and parental preferences and decision making for unscheduled paediatric healthcare - systematic review.

INTRODUCTION: Health systems offer access to unscheduled care through numerous routes; however, it is typically provided by general practitioners (GPs), by emergency medicine doctors in in emergency departments (EDs) and by GPs in out-of-hours GP services such as practitioner cooperatives. Unscheduled healthcare constitutes a substantial portion of healthcare delivery. A systematic review was conducted to establish the factors that influence parents' decision making when seeking unscheduled healthcare for their children. The systematic review question was "What are the factors that influence the decision making of parents and families seeking unscheduled paediatric healthcare?" METHOD: Five databases (CINAHL, PubMed, SCOPUS, PsycInfo, EconLit) and four grey literature databases (Proquest, Lenus, OpenGrey, Google Scholar) were searched. The titles and abstracts of 3746 articles were screened and full-text screening was performed on 177 of these articles. Fifty-six papers were selected for inclusion in the review. Data relating to different types of unscheduled health services (namely primary care, the emergency department and out-of-hours services) were extracted from these articles. A narrative approach was used to synthesise the extracted data. RESULTS: Several factors were identified as influencing parental preferences and decision making when seeking unscheduled healthcare for their children. A number of the included studies identified pre-disposing factors such as race, ethnicity and socioeconomic status (SES) as impacting the healthcare-seeking behaviour of parents. Unscheduled healthcare use was often initiated by the parent's perception that the child's condition was urgent and their need for reassurance. The choice of unscheduled service was influenced by a myriad of factors such as: waiting times, availability of GP appointments, location of the ED, and the relationship that the parent or caregiver had with their GP. CONCLUSION: Policy and planning initiatives do not always reflect how patients negotiate the health system as a single entity with numerous entry points. Altering patients' behaviour through public health initiatives that seek to improve, for instance, health literacy or reducing emergency hospital admissions through preventative primary care requires an understanding of the relative importance of factors that influence behaviour and decision making, and the interactions between these factors.

Development of an integrative coding framework for evaluating context within implementation science.

BACKGROUND: This research aims to explore an identified gap in implementation science methodology, that is, how to assess context in implementation research. Context is among the strongest influences on implementation success but is a construct that is poorly understood and reported within the literature. Consequently, there is little guidance on how to research context. This study addresses this issue by developing a method to account for the active role of context during implementation research. Through use of a case study, this paper demonstrates the value of using our context coding framework. METHODS: The developed context coding framework was guided by the sub-elements of the Consolidated Framework for Implementation Research (CFIR). Employing a constructivist approach, this framework builds on the CFIR and enables a deeper exploration of context at multiple levels of the health system. The coding framework enables the collation of various data sources such as organisational reports, culture audits, interview, survey, and observational data. It may be continuously updated as new data emerge and can be adapted by researchers as required. A pre-existing rating criterion has been integrated to the context coding framework to highlight the influence and relative strength of each contextual factor prior to and during implementation. RESULTS: It is anticipated that the context coding framework will facilitate a standardised approach to assessing context. This will provide a deeper understanding of how to account for the influence of context, ultimately providing guidance that should increase the likelihood of implementation success. The coding framework enables implementation progress to be monitored, facilitating the identification of contextual changes and variations across settings at different levels of the healthcare system. It is expected this framework will inform the selection of appropriate implementation strategies and enable the monitoring of such strategies regarding their impact on local context. CONCLUSIONS: This research contributes to the extant literature by advancing methodologies for the consideration and assessment of context in implementation research. This context coding framework may be used in any setting to provide insight into the characteristics of particular contexts throughout implementation processes.

Application of the critical incident technique in refining a realist initial programme theory.

BACKGROUND: As realist methodology is still evolving, there is a paucity of guidance on how to conduct theory driven interviews. Realist researchers can therefore struggle to collect interview data that can make a meaningful contribution to refining their initial programme theory. Collecting data to inform realist Inital Programme Theories (IPTs) in healthcare contexts is further compounded due to the healthcare workers' busy work schedules. In this case study of team interventions in acute hospital contexts, we explore the benefits of using the Critical Incident Technique (CIT) in order to build and refine an initial programme theory. We contend that use of the CIT helps to draw on more specific experiences of "Key Informants" and therefore elicits richer and more relevant data for realist enquiry. METHODS: The five steps of the CIT were mapped against realist methods guidance and adapted into an interview framework. Specifications to identify an incident as "critical" were agreed. Probes were embedded in the interview framework to confirm, refine and/or refute previous theories. Seventeen participants were interviewed and recordings were transcribed and imported for analysis into NVivo software. Using RAMESES guidelines, Context-Mechanism-Outcomes configurations were extrapolated from a total of 31 incidents. RESULTS: We found that the CIT facilitated construction of an interview format that allowed participants to reflect on specific experiences of interest. We demonstrate how the CIT strengthened initial programme theory development as it facilitated the reporting of the specifics of team interventions and the contexts and mechanisms characteristic of those experiences. As new data emerged, it was possible to evolve previous theories synthesised from the literature as well as to explore new theories. CONCLUSIONS: Utilising a CIT framework paid dividends in terms of the relevance and usefulness of the data for refining the initial programme theory. Adapting the CIT questioning technique helped to focus the participants on the specifics relating to an incident allowing the interviewers to concentrate on probes to explore theories during the interview process. The CIT interview format therefore achieved its purpose and can be adapted for use within realist methodology.

Team interventions in acute hospital contexts: a systematic search of the literature using realist synthesis.

BACKGROUND: Research on team effectiveness in healthcare has focussed on whether effective teams yield positive outcomes for patients and on the effectiveness of team interventions to improve performance. Limited understanding exists of what works for whom within an effective team, or how and why the context in which the team operates enables team members both as individuals and as a collective to enact behaviours that promote positive outcomes. METHODS: This realist synthesis of the literature explores the relationship between team interventions, underlying teamwork mechanisms generated by those interventions, and the resultant impact on patient outcomes in an acute hospital context. A systematic search of five healthcare and healthcare management academic databases: PubMed, PsychINFO, CINAHL, ABInform, Emerald Management and three grey literature databases: ERIC, OpenDOAR and Open Grey was undertaken. Five experts in the field were also contacted to source relevant literature. Using PRISMA guidelines, relevant studies published between January 2006 and January 2017 were systematically searched by a team of three people. Drawing on realist methodology, data were synthesised using context, mechanism and outcome configurations as the unit of analysis to identify enablers and barriers to effective team interventions. RESULTS: Out of 3347 papers retrieved, 18 were included in the final synthesis. From these, five contextual enablers were identified: an inter-disciplinary focus and flattened hierarchy; effective communication; leadership support and alignment of team goals with organisational goals; credibility of intervention; and appropriate team composition with physician involvement. Ten recurring mechanisms were identified, the most frequently occurring of which was shared responsibility. CONCLUSIONS: The advantage of using realist synthesis to extrapolate data from the literature is that it considers the context and mechanisms that will impact effectiveness of healthcare team interventions. This methodological approach provides a different perspective to other types of syntheses and offers insight as to why certain contextual elements may yield more success than others. Findings therefore tend to have more practical implications. Specificity of detail in terms of how external drivers impact on healthcare team interventions was limited in the articles extracted for analysis. This broader perspective is therefore an important consideration for future research.

PO-02 - Retrospective audit of the Peripherally Inserted Central Catheter (PICC) associated thrombosis in patients with haematological malignancies at Cork University Hospital.

INTRODUCTION: Peripherally inserted central catheters (PICC) have been increasingly used for administration of chemotherapy, antibiotics and blood products in patients with haematological malignancies. Although generally regarded safe, infections and thrombotic events have occurred with PICC use, necessitating study to guide future clinical prophylaxis and management. AIM: 1) Determine the incidence of PICC associated thrombosis in patients with haematological malignancies 2) To identify clinically significant risk factors contributing to these complications. MATERIALS AND METHODS: This was a cohort study, conducted in Cork University Hospital, between January 2010 and June 2015. After ethical approval Picture Archiving and Communication System (PACS) in radiology was used. All adult patients with PICC inserted under haematology were identified. A total of 90 patients with haematological malignancies who had PICC line placement were included. Patients' charts were reviewed in the medical record department. Data was collected using proforma sheets. This included patients demographs, type of malignancy, size of the PICC line, and total days of insertion. Haematological laboratory parameters were also recorded. The main outcome measures were PICC associated thrombosis and/or infection RESULTS: Of 131 PICC placements in a total of 90 patients. Out of these total PICC episodes 28.2% developed complications (n=37) and lead to removal. Thrombosis was found in 14.5% (n=19), 13.7% developed infection (n=18) and remaining were without complications. Of those with thrombosis (n=19), 7 patients had a diagnosis of Multiple Myeloma and 6 had Acute Myeloid Leukaemia. Whereas those with PICC associated infection (n=18), 5 had Non-Hodgkin's lymphoma and 5 had Acute Lymphoid Leukaemia. Diagnosis was significantly associated with complication (p=0.019). The mean age of patients who has PICC associated thrombosis was 51.6 years (±8.1 years). PICC removal as a result of complications was associated with increasing PICC lumen size; 30% of 5-French PICCs necessitated removal whereas 79.2% of 6-French PICCs necessitated removal (p=0.01). In addition, increased PICC lumen size was associated with clinically evident thrombophlebitis; 30% of 5-French PICCs displayed thrombophlebitis vs. 77%of 6-French PICCs displayed thrombophlebitis (p=0.017). Decreased in PICC lumen size was shown to influence the risk of complications; of 5 French catheters, 20% had thrombosis and 15% had infection, vs. 6 French catheters (13% and 13% respectively). Men were found to experience complications earlier with 80% of men having complications 1-50 days post PICC insertion and 12% 51-100 days post insertion. CONCLUSIONS: The risk of complications of PICC line insertion is relatively high in patients with haematological malignancies. Our institute thrombosis rate is similar to other studies. Haematological diagnosis was significantly associated with complication risk. Increased PICC lumen size was associated with higher removal rates as a result of complications and clinical signs of thrombophlebitis.

Cardiovascular manifestations of pediatric HIV infection.

Infection with human immunodeficiency virus (HIV) has become a major pediatric health concern in the United States and around the world. Pediatric HIV infection is a multisystem illness that presents an ongoing challenge to practicing nurses. Most clinical cardiovascular diseases in children with HIV have been underreported, and often are clinically occult. The preclinical detection of cardiovascular abnormalities results in early therapeutic interventions and reduces cardiovascular morbidity and mortality. Cardiovascular involvement is important in the natural history and prognosis of HIV infection.
