Homogenization and analysis of an expanded long-term monthly rainfall network for the Island of Ireland (1850–2010)

Long-term precipitation series are critical for understanding emerging changes to the hydrological cycle. To this end we construct a homogenized Island of Ireland Precipitation (IIP) network comprising 25 stations and a composite series covering the period 1850–2010, providing the second-longest regional precipitation archive in the British-Irish Isles. We expand the existing catalogue of long-term precipitation records for the island by recovering archived data for an additional eight stations. Following bridging and updating of stations HOMogenisation softwarE in R (HOMER) homogenization software is used to detect breaks using pairwise and joint detection. A total of 25 breakpoints are detected across 14 stations, and the majority (20) are corroborated by metadata. Assessment of variability and change in homogenized and extended precipitation records reveal positive (winter) and negative (summer) trends. Trends in records covering the typical period of digitization (1941 onwards) are not always representative of longer records. Furthermore, trends in post-homogenization series change magnitude and even direction at some stations. While cautionary flags are raised for some series, confidence in the derived network is high given attention paid to metadata, coherence of behaviour across the network and consistency of findings with other long-term climatic series such as England and Wales precipitation. As far as we are aware, this work represents the first application of HOMER to a long-term precipitation network and bodes well for use in other regions. It is expected that the homogenized IIP network will find wider utility in benchmarking and supporting climate services across the Island of Ireland, a sentinel location in the North Atlantic.

Knowledge and perceived competence among nurses caring for the dying in long-term care homes

Background: The quality of care provided to dying long-term care (LTC) residents is often inadequate, which may be due to the lack of formal training that LTC staff receive in palliative care (PC). This cross-sectional study assessed PC knowledge and self-efficacy in ability to provide PC in a sample of registered nurses working in LTC homes. Method: A survey was conducted in four LTC homes in October 2009 to June 2010. Nursing staff knowledge of PC was evaluated using the Palliative Care Quiz for Nurses (PCQN). The Self-Efficacy in End-of-Life Care Survey (S-EOLC) was used to measure nursing staff confidence in their ability to provide PC. Findings: Close to 60% of the nursing staff participated (69 of 119). The participants did not score highly on the PCQN: the average correct score ranged from 52.50% to 63.41% across the homes. There were no significant differences between the homes for the mean number of correct responses on the PCQN (P=0.329) or mean scores for the three S-EOLC subscales. Rank ordering of the percentage of correct PCQN answers by item and LTC home demonstrated that similar misconceptions were held across homes. Conclusion: Despite their confidence in PC practice, the participants' PC knowledge gap reveals a need for PC training for staff working in LTC homes. The PC education and training provided should both include a gerontological perspective and address the expertise and knowledge already held by staff.

Efficacy and Long-Term Outcomes of Palivizumab Prophylaxis to Prevent Respiratory Syncytial Virus Infection in Infants with Cystic Fibrosis in Northern Ireland

BACKGROUND: RSV causes considerable morbidity and mortality in children. In cystic fibrosis (CF) viral infections are associated with worsening respiratory symptoms and bacterial colonization. Palivizumab is effective in reducing RSV hospitalization in high risk patient groups. Evidence regarding its effectiveness and safety in CF is inconclusive. CF screening in N. Ireland enabled timely palivizumab prophylaxis, becoming routine in 2002.

OBJECTIVES: To determine the effect of palivizumab on RSV-related hospitalization and compare lung function and bacterial colonization at age 6 years for those born pre- and post-introduction of palivizumab prophylaxis.

METHODS: A retrospective audit was conducted for all patients diagnosed with CF during the period from 1997 to 2007 inclusive. RSV-related hospitalization, time to Pseudomonas aeruginosa (PA) 1st isolate, lung function and growth parameters were recorded. Comparisons were made for outcomes pre- and post-introduction of routine palivizumab administration in 2002. A cost evaluation was also performed.

RESULTS: Ninety-two children were included; 47 pre- and 45 post-palivizumab introduction. The overall RSV-positive hospitalization rate was 13%. The relative risk of RSV infection in palivizumab non-recipients versus recipients was 4.78 (95%CI: 1.1-20.7), P = 0.027. Notably, PA 1st isolate was significantly earlier in the palivizumab recipient cohort versus non-recipient cohort (median 57 vs. 96 months, P < 0.025) with a relative risk of 2.5. Chronic PA infection at 6 years remained low in both groups, with similar lung function and growth parameters. Total costs were calculated at £96,127 ($151,880) for the non-recipient cohort versus £137,954 ($217,967) for the recipient cohort.

CONCLUSION: Palivizumab was effective in reducing RSV-related hospitalization infection in CF patients. Surprisingly, we found a significantly earlier time to 1st isolate of PA in palivizumab recipients which we could not explain by altered or improved diagnostic tests. 

School Neighborhood Disadvantage as a Predictor of Long-Term Sick Leave Among Teachers: Prospective Cohort Study

This ongoing prospective study examined characteristics of school neighborhood and neighborhood of residence as predictors of sick leave among school teachers. School neighborhood income data for 226 lower-level comprehensive schools in 10 towns in Finland were derived from Statistics Finland and were linked to register-based data on 3,063 teachers with no long-term sick leave at study entry. Outcome was medically certified (> 9 days) sick leave spells during a mean follow-up of 4.3 years from data collection in 2000-2001. A multilevel, cross-classified Poisson regression model, adjusted for age, type of teaching job, length and type of job contract, school size, baseline health status, and income level of the teacher's residential area, showed a rate ratio of 1.30 (95% confidence interval: 1.03, 1.63) for sick leave among female teachers working in schools located in low-income neighborhoods compared with those working in high-income neighborhoods. A low income level of the teacher's residential area was also independently associated with sick leave among female teachers (rate ratio = 1.50, 95% confidence interval: 1.18, 1.91). Exposure to both low-income school neighborhoods and low-income residential neighborhoods was associated with the greatest risk of sick leave (rate ratio = 1.71, 95% confidence interval: 1.27, 2.30). This study indicates that working and living in a socioeconomically disadvantaged neighborhood is associated with increased risk of sick leave among female teachers.

Effects of the Interaction Between Reaction Component of Personal Need for Structure and Role Perceptions on Employee Attitudes in Long-Term Care for Elderly People

This study examined the interaction of reaction component of personal need for structure (reaction to lack of structure, RLS) and role perceptions in predicting job satisfaction, job involvement, affective commitment, and occupational identity among employees working in long-term care for elderly people. High-RLS employees experienced more role conflict, had less job satisfaction, and experienced lower levels of occupational identity than did low-RLS employees. We found individual differences in how problems in roles affected employees' job attitudes. High-RLS employees experienced lower levels of job satisfaction, job involvement, and affective commitment, irrespective of role-conflict levels. Low-RLS employees experienced detrimental job attitudes only if role-conflict levels were high. Our results suggest that high-RLS people benefit less from low levels of experienced role conflicts.

Perceptions of resident behavior problems and their clinical management in Long Term Care facilities

The objective of this study was to describe the perceptions of Long Term Care (LTC) service providers in urban Canadian care facilities regarding the prevalence and nature of resident behavior problems and how staff manage these problems. Key informants from 15 LTC facilities housing 1,928 residents, participated in a cross sectional survey which employed semi-structured telephone interviews. Respondents estimated that on average 61% (n = 1,176) of residents had some type of mental health/behavioral problem, with facility estimates ranging from 20% to 90%. The most frequently reported problem behaviors included: general agitation and restlessness (36%); pacing and aimless wandering (28%); hoarding things (24%); hitting either self or others (23%); and verbal aggression (22%). Behaviors reported by respondents as "disruptive" or "very disruptive" were screaming (13%), sexual disinhibition (10%), and hitting either self or others (10%). The most common interventions used by staff were behavioral interventions followed by the use of medications. Low levels of staffing and educational training of staff were among the most common factors recognized as contributing to the difficulty in caring for residents with mental health needs.

Comparing long-term placements for young children in care: The care pathways and outcomes study - Northern Ireland

When deciding on a long-term placement for a young child in care, a key challenge is to identify one that will enable children to achieve their full potential and enhance their health and wellbeing in the longer term. However, there is a dearth of research evidence that compares how children fare in the longer term across placement options.

The Care Pathways and Outcomes study is one of a small number of studies internationally that takes this form of longitudinal comparative approach. Since 2000, it has been tracking the placement profile for a population of children who were under the age of five and in care in Northern Ireland on a particular census day, and gathering comparative data on how the children and their parents/carers have been coping across the different types of placements provided.

This book reports on the most recent phase of the study, which involved interviews with a sub-group of the children (aged 9 to 14) and their parents/carers in adoption, foster care, kinship care, on residence order, and living with birth parents. Similarities and differences were explored between placement types, in terms of children’s attachment, self-concept, education, health and behaviour, their carers’ stress, social support, family communication, and contact with birth families.

This contemporary study contributes to evidence-based practice and provides a research base for decision-making throughout the UK.

Long-term neuropsychological and psychosocial outcomes of decompressive hemicraniectomy following malignant middle cerebral artery infarctions

Purpose: This study examines long-term neuropsychological and psychosocial outcomes of survivors of malignant middle cerebral artery infarction treated via decompressive hemicraniectomy. Method: A case series design facilitated a detailed analysis of the outcomes among five participants. Neuropsychological domains assessed included premorbid and current IQ, sustained, selective and divided attention, visual and auditory memory, executive functioning and visuo-spatial ability. Psychosocial domains assessed included self-rated depression, anxiety and quality of life. Participants and their main carer were asked about their retrospective view of surgery. Results: All participants showed neuropsychological impairments in multiple cognitive domains, with preserved ability in others. Effects of laterality of brain function were evident in some domains. Clinically significant depression was evident in two participants. Overall quality of life was within average limits in three of four assessed participants. Four participants retrospectively considered surgery as having been a favourable course of action. Conclusion: While neuropsychological impairments are highly likely post-surgery, preserved abilities and social support may serve a protective function against depression and an unacceptably poor quality of life. Results do not support the suggestion that decompressive hemicraniectomy following malignant middle cerebral artery infarction necessarily leads to unacceptable neuropsychological or psychosocial outcomes.
