Objective: Since 2012, all community care recipients in New Zealand have undergone a standardised needs assessment using the Home Care International Residential Assessment Instrument (interRAI‐HC). This study describes the national interRAI‐HC population, assesses its data quality and evaluates its ability to be matched.
Methods: The interRAI‐HC instrument elicits information on 236 questions over 20 domains; conducted by 1,800+ trained health professionals. Assessments between 1 July 2012 and 30 June 2014 are reported here. Stratified by age, demographic characteristics were compared to 2013 Census estimates and selected health profiles described. Deterministic matching to the Ministry of Health's mortality database was undertaken.
Results: Overall, 51,232 interRAI‐HC assessments were conducted, with 47,714 (93.1%) research consent from 47,236 unique individuals; including 2,675 Māori and 1,609 Pacific people. Apart from height and weight, data validity and reliability were high. A 99.8% match to mortality data was achieved.
Conclusions: The interRAI‐HC research database is large and ethnically diverse, with high consent rates. Its generally good psychometric properties and ability to be matched enhances its research utility.
Implications: This national database provides a remarkable opportunity for researchers to better understand older persons’ health and health care, so as to better sustain older people in their own homes.
The most common type ofdiaphragmatic defect was a posterolateral hernia (92%), followed in frequency by an eventration of the diaphragm (50 %), the least common defect being a retrocostosternal hernia (2%). Diaphragmatic hernia appears to be aetiologically as well as anatomically heterogeneous. In this series there were two cases of trisomy 18, one case of trisomy 21, one case trisomic for a small part of chromosome 20, and two cases with the Pierre Robin syndrome. It seems likely that diaphragmatic hernia is a non-specific consequence of several teratological processes.
Although colonization of atopic dermatitis by Staphylococcus aureus is universal and bacterial infection is common, it is not known whether antibiotic therapy is helpful in eczematous children who do not have any signs suggestive of bacterial infection. Fifty children aged 1-16 years with atopic dermatitis took part in a randomized double-blind placebo-controlled study of 4 weeks treatment with oral flucloxacillin, with an 8-week follow-up period. The change in the mean of the log10 of the counts/cm2 of S. aureus after 4 weeks of treatment was significantly different for patients receiving treatment, compared with the change for those receiving the placebo (P = 0.008). However, the difference in the change at 14 days after stopping treatment was not significant (P = 0.32). Methicillin-resistant strains of S. aureus were cultured from five children during or after treatment. Flucloxacillin did not improve the symptoms or clinical appearance of atopic dermatitis and only temporarily changed skin colonization by S. aureus.
SUMMARY One hundred and ninety children with atopic eczema were studied prospectively for two and a half years. The mean period of observation was 13 months. Seventy six children (40%) had between them 164 episodes of exacerbation of eczema due to bacterial infection, and in 52 (32%) infection recurred within three months of a previous infection. Twenty five episodes (15%) led to admission to hospital. Staphylococcus aureus was recovered in 97% of episodes, in combination with PI haemolytic streptococci in 62%. Physical signs suggesting infection were pustules, crusting, and a weeping discharge, but these signs alone are not diagnostic, and an exacerbation was only attributed to infection if there was a response to anti-infective treatment. Exacerbation of atopic eczema due to bacterial infection is common, the physical signs of infection are not always clear, and there is a case for a trial of oral antibiotics in any child with troublesome atopic eczema.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
