Retrospective review of factors associated with severe hospitalised community-acquired influenza in a tertiary paediatric hospital in South Australia.

ABSTRACT: BACKGROUND:Influenza infection can result in severe disease with debilitating complications. Young children have the highest rate of influenza hospitalisations with various factors influencing influenza susceptibility and severity. OBJECTIVES:This study aimed to determine the disease burden and assess risk factors for severe hospitalised influenza in South Australian children under 5 years of age. METHODS:Influenza admissions to the tertiary paediatric hospital in South Australia from 2008 to 2012 were identified. Data from laboratory-confirmed influenza cases were collected, including infecting influenza strain, co-infections, prematurity, pre-existing medical comorbidities and other potential risk factors. Predictors of high-level care were assessed using logistic regression. RESULTS:A total of 267 children with laboratory-confirmed influenza were hospitalised. Of these, 147 admissions (53%) occurred in children without underlying medical risk factors. Eighteen children (7%) required high-level care, of which 11 (61%) had no underlying medical risk factors. No deaths were reported. The majority of children were unimmunised against influenza. Co-infections were identified in 40% of children (n = 107). Influenza B was associated with a requirement for higher care (OR 3.7, CI 1.3-10.9, P = .02) as was a history of food allergies (OR 9.7, CI 1.5-61.4, P = .02) and iron deficiency anaemia (OR 4.8, CI 1.4-16.1, P = .01). CONCLUSIONS:Influenza can be a severe illness, even in children without underlying medical conditions. The identification of Influenza B strain, history of food allergies and iron deficiency anaemia as predictors of severity in hospitalised cases warrants further investigation and may have important implications for preventative strategies to reduce the burden of childhood influenza.

Project description:IntroductionSickle cell disease (SCD) remains a major cause of childhood mortality and morbidity in Malawi. However, literature to comprehensively describe the disease in the paediatric population is lacking.MethodsA retrospective review of clinical files of children with SCD was conducted. Descriptive statistics were performed to summarise the data. χ2 or Fisher's exact test was used to look for significant associations between predictor variables and outcome variables (case fatality and length of hospital stay). Predictor variables that were significantly associated with outcome variables (p≤0.05) in a χ2 or Fisher's exact test were carried forward for analysis in a binary logistic regression. A multivariable binary logistic regression was used to identify covariates that independently predicted length of hospital stay.ResultsThere were 16 333 paediatric hospitalisations during the study period. Of these, 512 were patients with SCD representing 3.1% (95% CI: 2.9%- 3.4%). Sixty-eight of the 512 children (13.3%; 95% CI: 10.5% - 16.5%) were newly diagnosed cases. Of these, only 13.2% (95% CI: 6.2% - 23.6%) were diagnosed in infancy. Anaemia (94.1%), sepsis (79.5%) and painful crisis (54.3%) were the most recorded clinical features. The mean values of haematological parameters were as follows: haemoglobin (g/dL) 6.4 (SD=1.9), platelets (×109/L) 358.8 (SD=200.9) while median value for white cell count (×109/L) was 23.5 (IQR: 18.0-31.2). Case fatality was 1.4% (95% CI: 0.6% - 2.8%)and 15.2% (95% CI: 12.2% -18.6%) of the children had a prolonged hospital stay (>5 days). Patients with painful crisis were 1.7 (95% CI: 1.02 - 2.86) times more likely to have prolonged hospital stay than those without the complication.ConclusionAnaemia, sepsis and painful crisis were the most common clinical features paediatric patients with SCD presented with. Patients with painful crisis were more likely to have prolonged hospital stay. Delayed diagnosis of SCD is a problem that needs immediate attention in this setting. Although somewhat encouraging, the relatively low in-hospital mortality among SCD children may under-report the true mortality from the disease considering community deaths and deaths occurring before SCD diagnosis is made.

Project description:ObjectivesAdverse childhood experiences (ACE) are associated with poor short, medium and long-term health outcomes. South Western Sydney (SWS) has a large culturally diverse population, including many disadvantaged population groups. Our aims were to determine the burden of ACE in children attending community paediatric (CP) clinics using a purposefully developed ACE checklist, and explore any association with developmental health of children.MethodsWe trialled the ACE checklist in all CP clinics including child development (CD) and vulnerable child (VC) clinics between February 2017 and August 2017. Data were collated from completed ACE checklists and relevant clinical information from CP clinics. Statistical analysis was performed using SPSS and MedCalc software.ResultsOf 279 children seen in CP clinics with checklists completed for the period, 167 (60%) attended CD clinics and 112 (40%) attended VC clinics. Seventy-eight (28%) had ACE ≥4 and 178 (64%) had ACE ≥1. Of those attending CD clinics, 8 (5%) had ACE ≥4 compared with 70 (63%) attending VC clinics (p<0.001). Of all age groups, children ≥10 years of age had the highest proportion of children with ACE ≥4 (65%); significant association between age group and ACE ≥4 (p<0.001). There was a significant association between cultural background and ACE ≥4 (p<0.001); indigenous children had the highest proportion of ACE ≥4 (n=21; 64%), followed by Anglo-Australian children (55%). On logistic regression analysis, only attending VC clinics was significantly associated with ACE ≥4. There was no significant association between ACE ≥4 and developmental health.ConclusionAmong children attending CP clinics in SWS, more than a quarter had a significant burden of ACE; those attending specialised clinics for vulnerable children, those from particular ethnic groups and from older age groups, had the highest burden of ACE. Our findings support the need for specialised pathways for paediatric assessment for vulnerable, at-risk children.

Project description:ObjectivesTo determine the strength and nature of the association between delirium and incident dementia in a population of older adult patients without dementia at baseline.DesignRetrospective cohort study using large scale hospital administrative data.SettingPublic and private hospitals in New South Wales, Australia between July 2001 and March 2020.ParticipantsData were extracted for 650 590 hospital patients aged ≥65 years. Diagnoses of dementia and delirium were identified from ICD-10 (international classification of diseases, 10th revision) codes. Patients with dementia at baseline were excluded. Delirium-no delirium pairs were identified by matching personal and clinical characteristics, and were followed for more than five years.Main outcome measuresCox proportional hazards models and Fine-Gray hazard models were used to estimate the associations of delirium with death and incident dementia, respectively. Delirium-outcome dose-response associations were quantified, all analyses were performed in men and women separately, and sensitivity analyses were conducted.ResultsThe study included 55 211 matched pairs (48% men, mean age 83.4 years, standard deviation 6.5 years). Collectively, 58% (n=63 929) of patients died and 17% (n=19 117) had a newly reported dementia diagnosis during 5.25 years of follow-up. Patients with delirium had 39% higher risk of death (hazard ratio 1.39, 95% confidence interval 1.37 to 1.41) and three times higher risk of incident dementia (subdistribution hazard ratio 3.00, 95% confidence interval 2.91 to 3.10) than patients without delirium. The association with dementia was stronger in men (P=0.004). Each additional episode of delirium was associated with a 20% increased risk of dementia (subdistribution hazard ratio 1.20, 95% confidence interval 1.18 to 1.23).ConclusionsThe study findings suggest delirium was a strong risk factor for death and incident dementia among older adult patients. The data support a causal interpretation of the association between delirium and dementia. The clinical implications of delirium as a potentially modifiable risk factor for dementia are substantial.

Project description:BackgroundInfluenza is one of the most common causes of acute respiratory tract infections around the world. Influenza viruses can cause seasonal epidemics. There remains limited information on the impact of both seasonal influenza A and influenza B related hospitalisations from neurological complications in paediatric populations in Asia.ObjectivesTo examine both the clinical spectrum and healthcare burden of influenza-associated neurological complications (IANCs) within the paediatric population of Hong Kong.MethodsWe conducted a population-based retrospective study to identify all paediatric patients (<18 years) admitted to a public hospital in Hong Kong with a confirmed influenza A or B infection between 2014 and 2018 using the Clinical Data Analysis and Reporting System of the Hospital Authority. The clinical spectrum of the paediatric patients with IANCs was studied. The clinical burden of paediatric influenza patients with IANCs were compared to paediatric influenza patients without neurological complications.ResultsA total of 28,016 children admitted to the paediatric wards diagnosed to have influenza A or B infection were identified, accounting for 5.7% (28,016/489,955) of total paediatric admissions. 67.3% had influenza A and 32.7% had influenza B, and 8.9% had IANCs. The mean annual incidence of IANCs in children was 57 per 100,000 population. The spectrum of IANCs in our paediatric patients included febrile seizures (80.6%), myositis (11.4%), seizures with fever (5.4%), influenza-associated encephalitis/encephalopathy (IAE) (2.6%) and rarely Guillain-Barré syndrome (0.04%). Most paediatric patients with IANCs (85.5%) presented at a young age of <6 years. Paediatric patients with IANCs had significant longer hospital stays (p < 0.001), higher percentages of mechanical ventilation use (p < 0.05) and PICU admissions (p < 0.001), and higher mortality rates (p < 0.001) compared to those without neurological complications. Amongst those with IANCs, IAE was the sole cause of all seven reported mortalities.ConclusionsSeasonal influenza A & B is a common cause of hospitalisation for paediatric patients in Hong Kong. We found neurological complications from influenza A and B caused a significantly higher clinical burden compared to those without neurological complications. Children in younger age groups (<6 years old) are at highest risk and thus increasing vaccination coverage to this age group is recommended.

Project description:Paediatric rheumatic disorders are common in children and result in significant impairment in quality of life, morbidity and mortality. There is limited information on the burden of these disorders in lower income countries especially in sub-Saharan Africa. Few case reports have documented presence of paediatric rheumatic disorders in Tanzania. This study was conducted to determine the spectrum of rheumatic disorders among children at Muhimbili National Hospital (MNH). This was a retrospective study conducted among children who were attended at MNH between January 2012 and August 2019. Paediatric patients seen in the out-patient clinics and those admitted in the wards were eligible. All patients with diagnosis of rheumatic disorders were identified from admission books and outpatient clinic logbooks, and later data were collected from their case notes and were recorded in clinical research forms. Collected information included age, sex, clinical features and laboratory tests results. A total of 52 children with mean age of 9.5?±?4.3?years, 12 (40.4%) participants were aged above 10?years and 32 (61.5%) were females. Frequently reported clinical presentations were joint pain 44 (84.6%), joint swelling 34 (65.4%), fever 24 (46.2%) and skin rashes 21(40.4%). Juvenile idiopathic arthritis (JIA) was the predominant diagnosis reported in 28 (53.8%) participants followed by juvenile systemic lupus erythematosus 8 (15.4%), mixed connective tissue diseases 4 (7.7%) and juvenile dermatomyositis 4 (7.7%). Antinuclear antibody test was performed in 16 participants it was positive in 9 (56.2%). Nine participants were tested for anti-double stranded DNA test and 5 (55.6%) were positive for this test. C-reactive protein was tested in 46 participants out of which 32 (69.6%) had elevated levels. HIV was tested in 24 (46.2%) participants and results were negative. Thirty-five out of 52 (67.3%) participants had anaemia. Predominant drugs used for treatment of JIA include prednisolone and methotrexate. Paediatric rheumatic disorders are not uncommon in Tanzania-and were noted to affect more female children in this study. Predominant conditions included juvenile idiopathic arthritis (JIA), juvenile systemic lupus erythematosus (JSLE) and juvenile dermatomyositis (JDM).
