Aims: 1. Investigate the illness pathway of people dying of stroke in Singapore, New Zealand and Australia; and 2. Undertake a comparison of the needs of people dying of stroke between these countries. Methods: A pilot retrospective medical record review was conducted with patients who died of stroke aged 18 years and over during 2008 to 2011 within acute care hospitals in Australia (n=10), New Zealand (n=10) and Singapore (n=7). This sample was designed to identify significant issues in the treatment and care of people who die of stroke, and will be used to inform a larger study. Sites chosen represented the key hospital for the treatment of people with stroke for a population of 200,000. Medical record data were collected using an agreed template and concerns of patients, relatives and health professionals were also extracted. One researcher led the analysis, which included descriptive statistics and thematic analysis. Electronic and telephone discussions between researchers ensured consistency of data. Principal findings: The majority of patients in Australia and New Zealand were transferred to stroke wards for care; those in Singapore were transferred to intensive care and lived longer. A stroke care pathway was followed in all countries, with a palliation pathway identified in two records (Australia and New Zealand). Palliative care was documented in the majority of Australian and New Zealand records. Concerns related to impaired consciousness and deterioration in patients' conditions. There was a lack of documented advance care plans and care directives; where present, staff had difficulty following them. Palliative care referral could make a difference to these patients and families. Conclusion: Stroke happens suddenly. Time to death is often short. This pilot indicates there is space for palliative care in the management of stroke patients to assist in end-of-life decision-making and symptom management. A larger study on this issue is justified. [ABSTRACT FROM AUTHOR]

Objective: This qualitative research study listens to the narratives of people experiencing the dying process who attended the Otago Community Hospice, Dunedin, New Zealand.Methods: Ten people, aged between 51 and 65, were approached; two declined and one died sooner than expected. All were women (although this was not part of the original design) and all had carcinoma. Data for the study was sought through qualitative research interviews, considering the development of each participant's illness in relation to her perception of her embodiment in the palliative care setting, and concluding with questions about what she wants the people who care for and about her to learn from her experience. Consistent with this phenomenological approach, the method of analysis was thematic and interpretive.Results: The main theme was the uncertainty that all participants felt throughout the diagnostic process and during treatment. Uncertainty, too, was a factor in how they managed their day, whether they would be able to sustain an outing or an activity or not and whether they would be pain free. None were afraid of dying but hoped that when they did die, they would do so comfortably. The relationship with their general practitioners varied. Where fatigue or the effects of medication were not an issue, they could think clearly, but their bodies were experienced as letting them down and limiting their activities. The ideal of "living until you die" was not able to be fulfilled. The increasing approach of social death as they withdrew from their employment and social responsibilities affected them.Significance Of Results: Whether one has a "good death" or not is determined not only by the progression and management of the disease process by health professionals, but also by the way in which one is perceived, by self and others. There are no guidelines for the dying role; everybody dies differently and individually. [ABSTRACT FROM AUTHOR]

Studies in both the UK and the USA continue to show that gay and bisexual men put themselves at risk of exposure to HIV through unprotected intercourse, most often with regular partners. As part of a larger study of homosexually active men, 310 men who had had unprotected anal intercourse with a man in the previous year were asked to describe the last occasion on which this had happened. The majority of men had had unprotected intercourse with a regular partner and did not perceived it as risky, although most did not know the HIV status of their partner. Regular and non-regular partners were perceived differently. Men were more likely to be emotionally involved in regular partners and to perceive unprotected penetrative sex with a regular partner as not risky. Future health education initiatives must take into account men's emotional involvement in regular partners and their perception of unprotected intercourse with such partners as not risky.

The importance of physical activity (PA) for the health and wellbeing of older adults is well documented, yet many older adults are insufficiently active. This issue is more salient in regional and rural areas, where evidence of the most critical components of interventions that explain PA participation and maintenance in older populations is sparse. This realist review will (1) systematically identify and synthesise literature on PA interventions in community-dwelling older adults in regional and rural areas, and (2) explore how and why those interventions increase PA in that population. Using a realist synthesis framework and the behaviour change wheel (BCW), context-mechanism-outcome (C-M-O) patterns of PA interventions for older adults in regional and rural areas will be synthesised. Thematic analysis will be employed to compare, contrast, and refine emerging C-M-O patterns to understand how contextual factors trigger mechanisms that influence regional and rural community-dwelling older adults' participation in PA interventions. This realist review will be the first to adopt a BCW analysis and a realist synthesis framework to explore PA interventions in community-dwelling older adults in regional and rural areas. This review will provide recommendations for evidence-based interventions to improve PA participation and adherence by revealing the important mechanisms apparent in this context.

Food and nutrition insecurity occurs when healthy and safe food cannot be obtained by socially acceptable means and arises as a result of complex interactions between socioeconomic and demographic determinants. These factors contribute to discrepancies in health and well-being between men and women and may also explain differential rates of food insecurity. The objectives of this cross-sectional study were to investigate the intersection between gender, education, nutrition knowledge and food security status within a high-income country context. Australian adults over 16 years of age who identified as having primary responsibility for food in their household were recruited via social media and a panel. Respondents completed a self-administered survey that included sociodemographic data, nutrition-related knowledge and food security status. Food security was measured using the Australian Household Food and Nutrition Security Scale an adapted version of the United States Department of Agriculture Household Food Security Survey. Among the 1010 survey respondents, household food insecurity (HFI) was highly prevalent (43% were food insecure, with 26% of these severely food insecure). Gender may affect associations between education, nutrition knowledge and HFI. Education was significantly associated with HFI among women but not among men. Conversely, nutrition knowledge was significantly inversely associated with food security among men but not among women. Differences in determinants of HFI exist between men and women, and programs aimed at addressing food insecurity may be more effective if tailored accordingly to account for the social and demographic factors associated with HFI., (© 2022 John Wiley & Sons Ltd.)

Australian National standards recommend routine screening for all adults over 65 years by health organisations that provide care for patients with cognitive impairment. Despite this, screening rates are low and, when implemented, screening is often not done well. This qualitative pilot study investigates barriers and facilitators to cognitive screening for older people in rural and regional Victoria, Australia. Focus groups and interviews were undertaken with staff across two health services. Data were analysed via thematic analysis and contextualized within the i-PARIHS framework. Key facilitators of screening included legislation, staff buy-in, clinical experience, appropriate training, and interorganisational relationships. Collaborative implementation processes, time, and workloads were considerations in a recently accredited tertiary care setting. Lack of specialist services, familiarity with patients, and infrastructural issues may be barriers exacerbated in rural settings. In lieu of rural specialist services, interorganisational relationships should be leveraged to facilitate referring 'outwards' rather than 'upwards'.

An ageing population, disproportionally affecting developing countries, increases demand on healthcare systems. Digital health offers access to healthcare for older people, particularly those residing in rural areas, as is the case for 71% of older adults in India. This research examined technology uptake and digital and health literacy (eHEALS) among a sample of 150 older adults in rural Mysore and Suttur, India. The study utilised mixed-method, with descriptive analysis of quantitative data and thematic analysis of qualitative data. Low rates of digital (11%) and health literacy (3-27% across domains) were identified. Mobile phone ownership was 50%, but very few owned or used a smartphone and less than 10% used the Internet to contact health professionals. Qualitative analysis found low technology usage, driven by limited exposure and confidence in using digital devices. Barriers to usage included poor traditional literacy and physical aspects of ageing like poor vision. Social support from neighbours, family and local primary healthcare staff may enable adoption of digital health. Access to healthcare through digital means among Indian rural older adults needs to consider low rates of both digital and health literacy and leverage the value of support from family and primary healthcare providers.

We examined the communicative intentions behind parents' deictic gesture use with high-risk infants later diagnosed with autism spectrum disorder (ASD; n = 17), high-risk infants who were not diagnosed with ASD (n = 25), and low-risk infants (n = 28) at 12 months and assessed the extent to which the parental deictic gesture intentions predicted infants' later vocabulary development. We found that parents in the three groups produced similar numbers of declarative and imperative gestures during a 10-minute parent-child interaction in the lab at 12 months and that 12-month parental declarative gesture use was significantly, positively associated with children's 36-month vocabulary scores. Encouraging parental use of declarative gestures with infants could have important implications for language development., (© 2021.

Children from food insecure households are more likely to have substandard food and nutritional intakes, and experience developmental delays, behaviour issues and increased use of health services. In Australia, screening for household food insecurity (HFI) within health services is not undertaken routinely, limiting opportunities to optimise nutrition and healthcare. This research aimed to (a) identify the prevalence, potential determinants and outcomes of HFI among paediatric outpatients in two Queensland hospitals; and (b) identify questions suitable for screening households at risk of HFI. A cross-sectional survey collected data from caregivers of children attending paediatric appointments at two hospitals in Brisbane, Australia (n = 148). Sociodemographic, health and household-related characteristics were collected, and food security status was assessed using four HFI measures. Chi-square, independent t-tests, ANOVA and logistic regression explored associations between HFI and health-related characteristics. A potential HFI screener was identified based on the most frequently endorsed questions from any HFI measure, and its validity was assessed through calculation of sensitivity and specificity. Prevalence of HFI was 41%, with 16% experiencing very low food security. Households with a child of 'fair/poor' health had 5.59 times greater odds of being food insecure than being food secure, compared to households with a child of 'excellent/good' health (aOR 5.59, 95% CI: 1.3-23.5). HFI was also positively associated with household chaos (p = .006). A combination of two questions was identified as a possible screening tool, with a sensitivity of 96% and a specificity of 90%. This study demonstrated HFI may be highly prevalent in a paediatric outpatient population, which may result in difficulties in being able to follow nutrition prescriptions. A highly sensitive and specific two-question screening tool was identified and may assist practitioners in paediatric healthcare settings in identifying clients who are at risk of HFI., (© 2020 John Wiley & Sons Ltd.)

Expressive language and communication are among the key targets of interventions for individuals with autism spectrum disorder (ASD), and natural language samples provide an optimal approach for their assessment. Currently, there are no protocols for collecting such samples that cover a wide range of ages or language abilities, particularly for children/adolescents who have very limited spoken language. We introduce a new protocol for collecting language samples, eliciting language samples for analysis (ELSA), and a novel approach for deriving basic measures of verbal communicative competence from it that bypasses the need for time-consuming transcription. Study 1 presents ELSA-adolescents (ELSA-A), designed for minimally and low-verbal older children/adolescents with ASD. The protocol successfully engaged and elicited speech from 46 participants across a wide range of ages (6;6-19;7) with samples averaging 20-25 min. The collected samples were segmented into speaker utterances (examiner and participant) using real-time coding as one is listening to the audio recording and two measures were derived: frequency of utterances and conversational turns per minute. These measures were shown to be reliable and valid. For Study 2, ELSA was adapted for younger children (ELSA-Toddler [ELSA-T]) with samples averaging 29 min from 19 toddlers (2;8-4;10 years) with ASD. Again, measures of frequency of utterances and conversational turns derived from ELSA-T were shown to have strong psychometric properties. In Study 3, we found that ELSA-A and ELSA-T were equivalent in eliciting language from 17 children with ASD (ages: 4;0-6;8), demonstrating their suitability for deriving robust objective assessments of expressive language that could be used to track change in ability over time. We introduce a new protocol for collecting expressive language samples, ELSA, that can be used with a wide age range, from toddlers (ELSA-T) to older adolescents (ELSA-A) with ASD who have minimal or low-verbal abilities. The measures of language and communication derived from them, frequency of utterances, and conversational turns per minute, using real-time coding methods, can be used to characterize ability and chart change in intervention research. LAY SUMMARY: We introduce a new protocol for collecting expressive language samples, ELSA, that can be used with a wide age range, from toddlers (ELSA-T) to older adolescents (ELSA-A) with autism spectrum disorder who have minimal or low-verbal abilities. The measures of language and communication derived from them, frequency of utterances and conversational turns per minute, using real-time coding methods, can be used to characterize ability and chart change in intervention research., (© 2020 International Society for Autism Research and Wiley Periodicals LLC.)

Aim: To describe the nature of readmission to acute care and identify patient characteristics associated with avoidable readmission to acute care from inpatient brain injury rehabilitation., Design: A retrospective cohort design., Methods: Data prospectively documented between 1 January 2012 -31 December 2018 in local clinical and administrative database were used. Patient medical records were accessed when missing data were identified. Descriptive statistics were used to describe the nature of readmission episodes and univariate and multivariable logistic regression were used to identify patient characteristics associated with readmission to acute care., Results: Of the 383 patients admitted for rehabilitation, 83 (22%) experienced readmission to acute care for a total of 171 episodes. Thirty-seven percent of readmission episodes were due to hospital acquired complications and therefore potentially avoidable. Infection accounted for 63% of hospital acquired complications. Patients with an avoidable readmission episode (N = 38) were more likely to have a significantly lower Functional Independence Measure score, be incontinent, have a tracheostomy, require a mobility aid, and be prescribed a dysphagia diet on rehabilitation admission. Patients with a tracheostomy on rehabilitation admission had a 56% probability for an avoidable readmission to acute care., Conclusion: Brain injury rehabilitation patients with an avoidable readmission to acute care were more likely to have a higher burden of care on rehabilitation admission and infection was the leading cause of avoidable readmission episodes., Impact: Research into readmission to acute care in the mixed brain injury inpatient rehabilitation population is limited. In this patient population, readmission to acute care is a contemporary issue that can occur at any time during a patient's rehabilitation admission. This study provides valuable information informing practice change for preventing avoidable readmission episodes. Locally developed policy aimed at preventing readmission episodes should include proactive prevention, early recognition of complications and discrete escalation care pathways., (© 2020 John Wiley & Sons Ltd.)

Aims and Objectives: To identify the predictors of unplanned readmission to acute care (RTAC) from inpatient brain injury rehabilitation and to develop a risk prediction model., Background: RTAC from inpatient rehabilitation is not uncommon. Individual rehabilitation patient populations require their own body of evidence regarding predictors of RTAC., Design: Retrospective cohort study., Methods: Adult patients with new onset acquired brain injury admitted to a stand-alone rehabilitation facility between 1 January 2012-31 December 2018 were included in the study. The main measures were RTAC, sensitivity, specificity, the C-statistic and Youden's index. This paper is reported using the Strengthening the Reporting of Observational Studies in Epidemiology guidelines., Results: Of 383 patients admitted for rehabilitation, 83 (22%) experienced a RTAC; 69 (18%) patients had at least one unplanned RTAC episode. Patients requiring unplanned RTAC were more likely to have lower Glasgow Coma Scale (GCS) and Functional Independence Measure (FIM) scores on rehabilitation admission, a higher burden of care on rehabilitation discharge and be discharged to a nonhome residence. Rehabilitation admission GCS and motor FIM were identified as the independent RTAC predictors in multivariate regression modelling. The combined C-statistic was 0.86. A GCS cut-off score of ≤14 and motor FIM cut-off score of ≤40 were identified as optimal, yielding a combined Youden's index of 0.56 (sensitivity = 0.72; specificity = 0.83)., Conclusion: Patients requiring an unplanned RTAC had a lower functional status on rehabilitation admission. A prediction model for unplanned RTAC has been developed using validated and readily available clinical measures., Relevance to Clinical Practice: The developed RTAC risk prediction model is the first step in preventing unplanned RTAC from inpatient brain injury rehabilitation. Future research should focus on discrete interventions for preventing unplanned RTAC from inpatient brain injury rehabilitation., (© 2019 John Wiley & Sons Ltd.)

Readmission to acute care (RTAC) from inpatient rehabilitation can have negative consequences for individuals and associated financial costs are increasing. Consequently, preventing avoidable RTAC represents a target for improvement in quality of care. The aim of this integrative review was to identify predictors of RTAC from inpatient rehabilitation. A systematic search of MEDLINE, EMBASE, ProQuest, and CINAHL databases was used. Thematic analysis was used to examine extracted data. Strong evidence indicating that the principal predictors of RTAC are lower functional status on admission to rehabilitation, a more severe injury and a higher number of comorbidities was identified in this review. This is despite the heterogeneous nature of impairment groups and factors/measures examined. However, the relevance of some predictors of RTAC (such as patient demographics, invasive devices and primary diagnoses) may be dependent on rehabilitation setting, impairment group or time between rehabilitation admission and RTAC (eg, below 3 vs 30 days). Consequently, findings of this integrative review highlight that RTAC is a complex, multifactorial patient issue with a complex interplay between the predictors and reasons for RTAC.

Objectives: To compare prevalence estimates of food insecurity using a single-item measure, with three adaptations of the United States Department of Agriculture Food Security Survey Module (USDA-FSSM)., Methods: Data were collected by postal survey, from individuals aged ≥18 years from disadvantaged suburbs of Brisbane, Australia (n= 505, 53% response). Food security status was ascertained by the Australian single-item measure, and the 6-, 10- and 18-item versions of the USDA-FSSM. Prevalence estimates of food insecurity and different levels of severity of food insecurity estimated by each tool were determined. Data were analysed using McNemar's test, polychoric correlation and Rasch analyses., Results: The prevalence of food insecurity was 19.5% using the single-item measure; significantly less than the 24.4%, 22.8% and 21.1% identified using the 18-item, 10-item and 6-item versions of the USDA-FSSM, respectively. Rasch analyses revealed that overall the USDA-FSSM may be a valid tool for the measurement of food insecurity within the current sample., Conclusion: The measure of food insecurity employed in national surveys in Australia may underestimate its prevalence and public health significance. Implications for public health: Future monitoring and surveillance efforts should seek to employ a more accurate measure as the first step in recognising the right to food for all Australians., (© 2018 The Authors.)

Objective: To investigate the psychometric properties, validity and reliability of a newly developed measure of food insecurity, the Household Food and Nutrition Security Survey (HFNSS), among an Australian population., Design: Cross-sectional study., Setting: Metropolitan areas of Melbourne, Australia, identified as very high, high or medium vulnerability in the 2008 Vulnerability Assessment for Mortgage, Petrol and Inflation Risks and Expenditure index., Subjects: A convenience sample of 134 adults (117 females and fifteen males, aged over 18 years)., Results: Rasch modelling and factor analysis identified four items for exclusion. The remaining items yielded excellent reliability among the current sample and assessed three underlying components: the adult experience of food insecurity (component one), initial/periodic changes to children's food intakes (component two) and progressive/persistent decreases in children's food intakes (component three). Compared with the widely used US Department of Agriculture Food Security Survey Module, the HFNSS identified a significantly higher proportion of food insecurity; this is likely due to the HFNSS's identification of food insecurity due to reasons other than (and including) limited financial access., Conclusions: The HFNSS may be a valid and reliable tool for the assessment of food insecurity among the Australian population and provides a means of assessing multiple barriers to food security beyond poor financial access (which has been identified as a limitation of other existing tools). Future research should explore the validity and reliability of the tool among a more representative sample, as well as specifically among vulnerable population subgroups.
