Difference between body composition of formula- and breastfed infants at birth.

Breastfeeding may reduce obesity risk, but this association could be confounded by breastfeeding families' characteristics. We investigated if body composition differs at birth among infants who were either exclusively breast- or formula-fed. We hypothesized the two groups would differ in body composition, even at birth, prior to their post-natal feeding experience. Healthy primiparous carrying singleton pregnancy were recruited at 15 weeks' gestation. PEA POD® measured body composition within 72 hours of delivery and infant feeding was prospectively captured. Out of the 1,152 infants recruited, 117 (10.2%) and 239 (20.7%) went on to be either exclusively breast- or formula-fed, respectively. Breastfed infants were heavier at birth, but their percentage fat mass (FM) was lower than that of exclusively formula-fed infants (covariate adjusted ß = -1.91 percentage points of FM; 95% CI -2.82 to -1.01). Differences in intra-uterine exposures, irrespective of early diet, may partly explain an infant's obesity risk.

Physical restraint: perceptions of nurse managers, registered nurses and healthcare assistants.

AIM: To examine the perceptions of nurse managers, registered nurses and healthcare assistants of physical restraint use on older people in a long-term care setting in the Republic of Ireland. BACKGROUND: The use of physical restraint, although controversial, persists in long-term care settings, despite recommendations for restraint-free environments. Perception and attitude of staff can influence use of physical restraint. METHODS: A descriptive cross-sectional design was used. A total of 250 nursing and healthcare assistant staff were recruited. A questionnaire incorporating demographics and the Perceptions of Restraint Use Questionnaire was used. Descriptive and inferential statistical analyses were conducted. RESULTS: Mean age of respondents (n = 156) was 41 years, and the majority were female. Overall, a low level of importance was attached to the use of restraint. Nurse managers and registered nurses compared favourably with healthcare assistants who attached a higher importance to use of restraint. Across all three staff groups, greatest importance was attached to the use of physical restraint for reducing falls, followed by prevention of treatment interference. Restraint was least favoured as a means of impairment management. Education was not an explanatory factor in perceived importance of physical restraint use. CONCLUSION: Nurse managers and registered nurses are unlikely to use physical restraint. However, there is concern regarding perception of healthcare assistants on use of restraint. IMPLICATIONS FOR NURSING AND HEALTH POLICY: Results from this study compare favourably with those in countries that have no policy on physical restraint use. Educational programmes alone are insufficient to address use of physical restraint. Attention to skill mix with adequate support for healthcare assistants in long-term care settings is recommended.

Measuring the Effect of Carers on Patients' Risk of Adverse Healthcare Outcomes Using the Caregiver Network Score.

BACKGROUND: Although caregivers are important in the management of frail, community-dwelling older adults, the influence of different caregiver network types on the risk of adverse healthcare outcomes is unknown. OBJECTIVE: To examine the association between caregiver type and the caregiver network subtest of The Risk Instrument for Screening in the Community (RISC), a five point Likert scale scored from one ("can manage") to five ("absent/liability"). To measure the association between caregiver network scores and the one-year incidence of institutionalisation, hospitalisation and death. DESIGN: Observational cohort study. SETTING AND PARTICIPANTS: Community-dwelling adults, aged >65, attending health centres in Ireland, (n=779). PROCEDURE AND MEASUREMENTS: The caregiver network subtest of the RISC was scored by public health nurses. Caregivers were grouped dichotomously into low-risk (score of one) or high-risk (scores two-five). RESULTS: The majority of patients had a primary caregiver (582/779; 75%), most often their child (200/582; 34%). Caregiver network scores were highest, indicating greatest risk, when patients had no recognised primary caregiver and lowest when only a spouse or child was available. Despite this, patients with a caregiver were significantly more likely to be institutionalised than those where none was required or identified (11.5% versus 6.5%, p=0.047). The highest one-year incidence of adverse outcomes occurred when state provided care was the sole support; the lowest when private care was the sole support. Significantly more patients whose caregiver networks were scored high-risk required institutionalisation than low-risk networks; this association was strongest for perceived difficulty managing medical domain issues, odds ratio (OR) 3.87:(2.22-6.76). Only perceived difficulty managing ADL was significantly associated with death, OR 1.72:(1.06-2.79). There was no association between caregiver network scores and risk of hospitalisation. CONCLUSION: This study operationalizes a simple method to evaluate caregiver networks. Networks consisting of close family (spouse/children) and those reflecting greater socioeconomic privilege (private supports) were associated with lower incidence of adverse outcomes. Caregiver network scores better predicted institutionalisation than hospitalisation or death.

Components of the Risk Instrument for Screening in the Community (RISC) that Correlate with Public Health Nurses' Perception of Risk.

BACKGROUND: Functional decline and frailty are common in community-dwelling older adults, leading to an increased risk of adverse outcomes. OBJECTIVE: To examine the factors that public health nurses perceive to cause risk of three adverse outcomes: institutionalisation, hospitalisation, and death, in older adults, using the Risk Instrument for Screening in the Community (RISC). DESIGN: A quantitative, correlational, descriptive design was used. SETTING AND PARTICIPANTS: A sample of 803 community-dwellers, aged over 65 years receiving regular follow-up by public health nurses. Procedure and Measurements: Public health nurses (n=15) scored the RISC and the Clinical Frailty Scale (CFS) on patients in their caseload. We examined and compared correlations between the severity of concern and ability of the caregiver network to manage these concerns with public health nurses' perception of risk of the three defined adverse outcomes. RESULTS: In total, 782 RISC scores were available. Concern was higher for the medical state domain (686/782,88%) compared with the mental state (306/782,39%) and activities of daily living (595/782,76%) domains. Concern was rated as severe for only a small percentage of patients. Perceived risk of institutionalisation had the strongest correlation with concern over patients mental state,(r=0.53), while risk of hospitalisation,(r=0.53) and death,(r=0.40) correlated most strongly with concern over the medical state. Weaker correlations were found for the other domains and RISC scores. The CFS most strongly correlated with the ADL domain,(r=0.78). CONCLUSION: Although the prevalence of concern was high, it was mostly rated as mild. Perceived risk of institutionalisation correlated most with concern over the ability of caregiver networks to manage patients' mental state, while risk of hospitalisation and death correlated with patients' medical state. The findings suggest the importance of including an assessment of the caregiver network when examining community-dwelling older adults. Validation of the RISC and public health nurses' ratings are now required.

The Community Assessment of Risk Instrument: Investigation of Inter-Rater Reliability of an Instrument Measuring Risk of Adverse Outcomes.

BACKGROUND: Frailty is increasingly common in community dwelling older adults and increases their risk of adverse outcomes. Risk assessment is implicit in the Aged Care Assessment Teams process, but few studies have considered the factors that influence the assessor's decision making or explored the factors that may contribute to their interpretation of risk. OBJECTIVE: to examine the inter-rater reliability of the Community Assessment of Risk Instrument (CARI), which is a new risk assessment instrument. DESIGN: A cohort study was used. SETTING AND PARTICIPANTS: A sample of 50 community dwelling older adults underwent comprehensive geriatric assessment by two raters: a geriatrician and a registered nurse. Procedure and measurements: Each participant was scored for risk by the two raters using the CARI. This instrument ranks risk of three adverse outcomes, namely i) institutionalisation, ii) hospitalisation and iii) death within the next year from a score of 1, which is minimal risk to 5, which is extreme risk. Inter-rater reliability was assessed with Gamma, Spearman correlation and Kappa statistics. Internal consistency was assessed with Cronbach's alpha. RESULTS: There were 30 female (mean age 82.23 years) and 20 male (mean age 81.75 years) participants. Items within domains showed good-excellent agreement. The gamma statistic was >0.77 on 6/7 Mental State items, 14/15 items in the Activities of Daily Living domain. In the Medical domain, 6/9 items had Gamma scores >0.80. The global domain scores correlated well, 0.88, 0.72 and 0.87. Caregiver network scores were 0.71, 0.73 and 0.51 for the three domains. Inter-rater reliability scores for global risk scales were 0.86 (institutionalisation) and 0.78 (death). The gamma statistic for hospitalisation was 0.29, indicative of lower inter-rater reliability. Cronbach's alpha was 0.86 and 0.83 for the Activities of Daily Living domain, 0.51 and 0.42 for the Mental state domain and 0.23 and 0.10 for the Medical state domain. CONCLUSIONS: Overall, the instrument shows good inter-rater reliability. Poor correlations on some items relate to poor communication of clinical data and variable interpretation based on professional background. Lack of internal consistency in the medical condition domain confirms the discrete nature of these variables.
