Rehabilitation Support via Postcard (RSVP): A Randomised Controlled Trial of a Postcard to Promote Uptake of Cardiac Rehabilitation.

PURPOSE: The aim was to increase cardiac rehabilitation (CR) uptake using a novel intervention, Rehabilitation Support Via Postcard (RSVP), among patients with acute myocardial infarction discharged from two major hospitals in Hunter New England Local Health District (HNELHD), New South Wales, Australia. METHODS: The RSVP trial was evaluated using a two-armed randomised controlled trial design. Participants (N=430) were recruited from the two main hospitals in HNELHD, and enrolled and randomised to either the intervention (n=216) or control (n=214) group over a six-month period. All participants received usual care; however, the intervention group received postcards promoting CR attendance between January and July 2020. The postcard was ostensibly written as an invitation from the patient's admitting medical officer to promote timely and early uptake of CR. The primary outcome was CR attendance at outpatient HNELHD CR services in the 30-days post-discharge. RESULTS: Fifty-four percent (54%) of participants who received RSVP attended CR, compared to 46% in the control group; however this difference was not statistically significant (odds ratio [OR]=1.4, 95% confidence interval [CI]=0.9-2.0, p=0.11). Exploratory post-hoc analysis among four sub-groups (i.e., Indigeneity, gender, age and rurality), found that the intervention significantly increased attendance in males (OR=1.6, 95%CI=1.0-2.6, p=0.03) but had no significant impact on attendance for other sub-groups. CONCLUSIONS: While not statistically significant, postcards increased overall CR attendance by 8%. This strategy may be useful to increase attendance, particularly in men. Alternative strategies are necessary to increase CR uptake among women, Indigenous people, older people and people from regional and remote locations.

Community perspectives of barriers indigenous women face in accessing maternal health care services in the Chittagong Hill Tracts, Bangladesh.

OBJECTIVES: Bangladesh has achieved notable success in improving maternal health by increasing women's access to good quality and low-cost maternal health care (MHC) services. However, the health system of Bangladesh has earned criticism for not ensuring equitable MHC access for all women, particularly for Indigenous women in the Chittagong Hill Tracts (CHT). Little is known about Indigenous communities' perspectives on these inequalities in MHC service access in the CHT. Therefore, this study aimed to explore Indigenous communities' perspectives on challenges and opportunities for improving MHC service access in the CHT. DESIGN: This qualitative descriptive study was conducted in two sub-districts of Khagrachhari between September 2017 and February 2018. Eight Indigenous key informants from three Indigenous communities (Chakma, Marma and Tripura) were recruited via snowballing and purposive techniques and participated in face-to-face, semi-structured interviews. Key informants comprised community leaders and health care providers. Data were analysed thematically using Nvivo12 software. RESULTS: Findings suggest that distance, poor availability of resources and infrastructure, lack of community engagement in the design of health interventions, Indigenous cultural beliefs, misconceptions about MHC services, and maltreatment from health care providers were the key barriers to accessing MHC services; all are interconnected. Indigenous women faced humiliation and maltreatment from MHC staff. Failure to provide a culturally-safe environment suggests a lack of cultural competency among health staff, including Indigenous staff. CONCLUSION: Findings suggest that cultural competency training for all health care providers is needed to improve cultural appropriateness and accessibility of services. Refresher training and undisrupted supply of basic MHC services for front-line care providers will benefit the entire community and will likely be cost-effective for the government. Designing health programmes through extensive community consultation is essential.

The role of the peer support worker in increasing rural mental health help-seeking.

OBJECTIVE: Mental health peer support workers draw on lived experience to provide benefit to people experiencing mental distress. People living in rural areas are less likely than their urban counterparts to seek professional help for psychological distress. The aim of this study was to explore the perceived value of rural peer support workers as facilitators to rural mental health help-seeking. DESIGN: Data were gathered through a cross-sectional survey distributed by a social media boosted post. SETTING: A total of 349 "small" rural towns in New South Wales as defined by the Modified Monash Model classification system as MMM5. PARTICIPANTS: A total of 765 adult, rural residents completed the survey. MAIN OUTCOME MEASURE(S): Participants were asked to select, from a list of potential facilitators, those which they felt would make mental health help-seeking easier or harder. RESULTS: Study participants felt that a help provider with lived experience of mental illness or distress would make mental health help-seeking easier. Similarly, rural life experience in a help provider was thought to facilitate help-seeking. Participants also believed that flexible and informal meeting settings would make it easier to seek help for mental distress. CONCLUSIONS: Engaging rural mental health peer support workers in a flexible/informal setting, as a complement to conventional health service provision, may increase rural help-seeking for mental distress. Increased mental health help-seeking is likely to have a positive impact on instances of serious mental illness.

Education on invasive mechanical ventilation involving intensive care nurses: a systematic review.

BACKGROUND: Intensive care unit nurses are critical for managing mechanical ventilation. Continuing education is essential in building and maintaining nurses' knowledge and skills, potentially improving patient outcomes. AIMS: The aim of this study was to determine whether continuing education programmes on invasive mechanical ventilation involving intensive care unit nurses are effective in improving patient outcomes. METHODS: Five electronic databases were searched from 2001 to 2016 using keywords such as mechanical ventilation, nursing and education. Inclusion criteria were invasive mechanical ventilation continuing education programmes that involved nurses and measured patient outcomes. Primary outcomes were intensive care unit mortality and in-hospital mortality. Secondary outcomes included hospital and intensive care unit length of stay, length of intubation, failed weaning trials, re-intubation incidence, ventilation-associated pneumonia rate and lung-protective ventilator strategies. Studies were excluded if they excluded nurses, patients were ventilated for less than 24 h, the education content focused on protocol implementation or oral care exclusively or the outcomes were participant satisfaction. Quality was assessed by two reviewers using an education intervention critical appraisal worksheet and a risk of bias assessment tool. Data were extracted independently by two reviewers and analysed narratively due to heterogeneity. RESULTS: Twelve studies met the inclusion criteria for full review: 11 pre- and post-intervention observational and 1 quasi-experimental design. Studies reported statistically significant reductions in hospital length of stay, length of intubation, ventilator-associated pneumonia rates, failed weaning trials and improvements in lung-protective ventilation compliance. Non-statistically significant results were reported for in-hospital and intensive care unit mortality, re-intubation and intensive care unit length of stay. CONCLUSION: Limited evidence of the effectiveness of continuing education programmes on mechanical ventilation involving nurses in improving patient outcomes exists. Comprehensive continuing education is required. RELEVANCE TO CLINICAL PRACTICE: Well-designed trials are required to confirm that comprehensive continuing education involving intensive care nurses about mechanical ventilation improves patient outcomes.

Investigation of a Suicide Ideation Risk Profile in People With Co-occurring Depression and Substance Use Disorder.

Disengagement from services is common before suicide, hence identifying factors at treatment presentation that predict future suicidality is important. This article explores risk profiles for suicidal ideation among treatment seekers with depression and substance misuse. Participants completed assessments at baseline and 6 months. Baseline demographics, psychiatric history, and current symptoms were entered into a decision tree to predict suicidal ideation at follow-up. Sixty-three percent of participants at baseline and 43.5% at follow-up reported suicidal ideation. Baseline ideation most salient when psychiatric illness began before adulthood, increasing the rate of follow-up ideation by 16%. Among those without baseline ideation, dysfunctional attitudes were the most important risk factor, increasing rates of suicidal ideation by 35%. These findings provide evidence of factors beyond initial diagnoses that increase the likelihood of suicidal ideation and are worthy of clinical attention. In particular, providing suicide prevention resources to those with high dysfunctional attitudes may be beneficial.

Unassisted detection of depression by GPs: who is most likely to be misclassified?

BACKGROUND: Meta-analyses indicate 50% of cases of depression are not detected by GPs. It is important to examine patient and GP characteristics associated with misclassification so that systems can be improved to increase accurate detection and optimal management for groups at risk of depression. OBJECTIVE: To examine patient and GP characteristics associated with GP misclassification of depression for patients classified by the Patient Health Questionnaire-9 as depressed. METHODS: A cross-sectional study within general practices in two states of Australia. GPs completed a one-page paper and pencil survey indicating whether they thought each patient was clinically depressed. Patients completed a computer tablet survey while waiting for their appointment to provide demographic information and indicate depression status. Chi-square analyses were used to determine whether patient and GP characteristics were associated with a false-negative and false-positive result. The probability of misclassification was modelled using Generalized Estimating Equations to account for clustering of patients. RESULTS: Fifty GPs from 12 practices participated. GPs completed surveys for 1880 patients. Younger patients aged 25-44, and those with a health care card were less likely to have a false-negative assessment. Patients with 0-3 GP visits in the past 12 months, and those with private health insurance were less likely to have a false-positive assessment. GPs who worked five sessions or fewer per week were more likely to make false-positive assessments.

Long-term effects of lifetime trauma exposure in a rural community sample.

BACKGROUND: This study examines the long-term outcomes of lifetime trauma exposure, including factors that contribute to the development of PTSD, in a sample of rural adults. METHODS: In 623 rural community residents, lifetime trauma exposure, PTSD, other psychiatric disorders and lifetime suicidal ideation were assessed using the World Mental Health Composite International Diagnostic Interview. Logistic regressions were used to examine relationships between potentially traumatic events (PTEs) and lifetime PTSD and other diagnoses. RESULTS: 78.2% of participants reported at least on PTE. Rates were broadly comparable with Australian national data: the most commonly endorsed events were unexpected death of a loved one (43.7%); witnessing injury or death (26.3%); and life-threatening accident (19.3%). While the mean age of the sample was 55 years, the mean age of first trauma exposure was 19 years. The estimated lifetime rate of PTSD was 16.0%. Events with the strongest association with PTSD were physical assault and unexpected death of a loved one. Current functioning was lowest among those with current PTSD, with this group reporting elevated psychological distress, higher mental health service use, a greater number of comorbidities, and lower perceived social support. Respondents with a past PTE but no PTSD history were generally similar in terms of their current wellbeing to those with no lifetime PTE. CONCLUSIONS: PTEs may have diverse psychological and social consequences beyond the development of PTSD. Ensuring that adequate support services are available in rural areas, particularly in the period immediately following a PTE, may reduce the long-term impact of traumatic events.

Predictors of suicidal ideation in older people: a decision tree analysis.

OBJECTIVES: Suicide among older adults is a major public health issue worldwide. Although studies have identified psychological, physical, and social contributors to suicidal thoughts in older adults, few have explored the specific interactions between these factors. This article used a novel statistical approach to explore predictors of suicidal ideation in a community-based sample of older adults. DESIGN: Prospective cohort study. PARTICIPANTS AND SETTING: Participants aged 55-85 years were randomly selected from the Hunter Region, a large regional center in New South Wales, Australia. MEASUREMENTS: Baseline psychological, physical, and social factors, including psychological distress, physical functioning, and social support, were used to predict suicidal ideation at the 5-year follow-up. Classification and regression tree modeling was used to determine specific risk profiles for participants depending on their individual well-being in each of these key areas. RESULTS: Psychological distress was the strongest predictor, with 25% of people with high distress reporting suicidal ideation. Within high psychological distress, lower physical functioning significantly increased the likelihood of suicidal ideation, with high distress and low functioning being associated with ideation in 50% of cases. A substantial subgroup reported suicidal ideation in the absence of psychological distress; dissatisfaction with social support was the most important predictor among this group. The performance of the model was high (area under the curve: 0.81). CONCLUSIONS: Decision tree modeling enabled individualized "risk" profiles for suicidal ideation to be determined. Although psychological factors are important for predicting suicidal ideation, both physical and social factors significantly improved the predictive ability of the model. Assessing these factors may enhance identification of older people at risk of suicidal ideation.

Determinants of suicidal ideation and suicide attempts: parallel cross-sectional analyses examining geographical location.

BACKGROUND: Suicide death rates in Australia are higher in rural than urban communities however the contributors to this difference remain unclear. Geographical differences in suicidal ideation and attempts were explored using two datasets encompassing urban and rural community residents to examine associations between socioeconomic, demographic and mental health factors. Differing patterns of association between psychiatric disorder and suicidal ideation and attempts as geographical remoteness increased were investigated. METHODS: Parallel cross-sectional analyses were undertaken using data from the 2007 National Survey of Mental Health and Wellbeing (2007-NSMHWB, n = 8,463), under-representative of remote and very remote residents, and selected participants from the Australian Rural Mental Health Study (ARMHS, n = 634), over-representative of remote and very remote residents. Uniform measures of suicidal ideation and attempts and mental disorder using the World Mental Health Composite International Diagnostic Interview (WMH-CIDI-3.0) were used in both datasets. Geographic region was classified into major cities, inner regional and other. A series of logistic regressions were undertaken for the outcomes of 12-month and lifetime suicidal ideation and lifetime suicide attempts, adjusting for age, gender and psychological distress. A sub-analysis of the ARMHS sample was undertaken with additional variables not available in the 2007-NSMHWB dataset. RESULTS: Rates and determinants of suicidal ideation and suicide attempts across geographical region were similar. Psychiatric disorder was the main determinant of 12-month and lifetime suicidal ideation and lifetime suicide attempts across all geographical regions. For lifetime suicidal ideation and attempts, marital status, employment status, perceived financial adversity and mental health service use were also important determinants. In the ARMHS sub-analysis, higher optimism and better perceived infrastructure and service accessibility tended to be associated with a lower likelihood of lifetime suicidal ideation, when age, gender, psychological distress, marital status and mental health service use were taken into account. CONCLUSIONS: Rates and determinants of suicidal ideation and attempts did not differ according to geographical location. Psychiatric disorder, current distress, employment and financial adversity remain important factors associated with suicidal ideation and attempts across all regions in Australia. Regional characteristics that influence availability of services and lower personal optimism may also be associated with suicidal ideation in rural communities.

Self-reported contacts for mental health problems by rural residents: predicted service needs, facilitators and barriers.

BACKGROUND: Rural and remote Australians face a range of barriers to mental health care, potentially limiting the extent to which current services and support networks may provide assistance. This paper examines self-reported mental health problems and contacts during the last 12 months, and explores cross-sectional associations between potential facilitators/barriers and professional and non-professional help-seeking, while taking into account expected associations with socio-demographic and health-related factors. METHODS: During the 3-year follow-up of the Australian Rural Mental Health Study (ARMHS) a self-report survey was completed by adult rural residents (N = 1,231; 61% female; 77% married; 22% remote location; mean age = 59 years), which examined socio-demographic characteristics, current health status factors, predicted service needs, self-reported professional and non-professional contacts for mental health problems in the last 12 months, other aspects of help-seeking, and perceived barriers. RESULTS: Professional contacts for mental health problems were reported by 18% of the sample (including 14% reporting General Practitioner contacts), while non-professional contacts were reported by 16% (including 14% reporting discussions with family/friends). Perceived barriers to health care fell under the domains of structural (e.g., costs, distance), attitudinal (e.g., stigma concerns, confidentiality), and time commitments. Participants with 12-month mental health problems who reported their needs as met had the highest levels of service use. Hierarchical logistic regressions revealed a dose-response relationship between the level of predicted need and the likelihood of reporting professional and non-professional contacts, together with associations with socio-demographic characteristics (e.g., gender, relationships, and financial circumstances), suicidal ideation, and attitudinal factors, but not geographical remoteness. CONCLUSIONS: Rates of self-reported mental health problems were consistent with baseline findings, including higher rural contact rates with General Practitioners. Structural barriers displayed mixed associations with help-seeking, while attitudinal barriers were consistently associated with lower service contacts. Developing appropriate interventions that address perceptions of mental illness and attitudes towards help-seeking is likely to be vital in optimising treatment access and mental health outcomes in rural areas.

Comparison of a single self-assessment item with the PHQ-9 for detecting depression in general practice.

BACKGROUND: Several factors need to be considered when selecting a screening tool for depression including accuracy, level of burden for patients and for staff to administer and follow-up. OBJECTIVE: This study aimed to explore the utility of a single self-assessment item in identifying possible cases of depression in primary care by examining sensitivity and specificity with the nine-item Patient Health Questionnaire (PHQ-9) at different thresholds. DESIGN: Cross-sectional survey presented on a touchscreen computer. PARTICIPANTS: Adult patients attending 12 urban general practices in Australia completed a health status questionnaire (n = 1004). MAIN MEASURES: Depression was assessed by the PHQ-9 and a single self-assessment item. Sensitivity, specificity, and positive and negative predictive values were calculated for the single item using a PHQ-9 score of 10 or more as the criterion value. KEY RESULTS: A total of 1004 participants (61% female, 48% aged 55 years or older) completed both the PHQ-9 and a single self-assessment item. When using a threshold of mild depression or greater, the single item had adequate specificity (76%, 95% CI: 71-80%), with 76 out of every 100 people defined as non-depressed by the PHQ-9 also identified as not depressed by the single item. Sensitivity was high (91%, 95% CI: 84-95%), with the single item identifying 91 out of every 100 true cases (as defined by the PHQ-9). CONCLUSIONS: The single self-assessment item has high sensitivity and moderate specificity to identify possible cases of depression when used at a threshold of mild depression or greater.

Feasibility of internet-delivered mental health treatments for rural populations.

PURPOSE: Rural populations face numerous barriers to mental health care. Although internet-delivered mental health treatments may offer an accessible and cost-effective answer to these barriers, there has been little evaluation of the feasibility of this approach among rural communities. METHODS: Data were obtained from a random rural community sample through the third wave of the Australian Rural Mental Health Study. Attitudes towards internet-delivered mental health treatments and availability of internet access were explored. Data were analysed to identify sub-groups in whom internet-delivered treatments may be usefully targeted. RESULTS: Twelve hundred and forty-six participants completed the survey (mean age 59 years, 61% females, 22% from remote areas). Overall, 75% had internet access and 20% would consider using internet-based interventions, with 18% meeting both of these feasibility criteria. Logistic regression revealed feasibility for internet-delivered mental health treatment was associated with younger age, male gender, being a carer, and a 12-month mental health problem. Participants who had used internet-delivered services in the past were significantly more likely to endorse these treatments as acceptable. CONCLUSIONS: There is considerable potential for internet-delivered treatments to increase service accessibility to some sub-groups, particularly among people with mental health problems who are not currently seeking help. Resistance to internet treatments appears to be largely attitudinal, suggesting that enhancing community education and familiarity with such programs may be effective in improving perceptions and ultimately access.

Education of ICU nurses regarding invasive mechanical ventilation: findings from a cross-sectional survey.

BACKGROUND: Continuing education for intensive care unit nurses on invasive mechanical ventilation is fundamental to the acquisition and maintenance of knowledge and skills to optimise patient outcomes. PURPOSE: We aimed to determine how intensive care unit nurses perceived current education provided on mechanical ventilation, including a self-directed learning package and a competency programme; identify other important topics and forms of education; and determine factors associated with the completion of educational programmes on invasive mechanical ventilation. METHODS: A cross-sectional, 30-item, self-administered and semi-structured survey on invasive mechanical ventilation education was distributed to 160 intensive care nurses. Analysis included descriptive statistics and logistic regression was used to determine factors associated with current education completion, reported as adjusted odds ratios (AOR) and 95% confidence intervals (CIs). FINDINGS: Eighty three intensive care unit nurses responded and the majority (63%) reported not receiving education about mechanical ventilation prior to working in intensive care. Using a Likert rating scale the self-directed learning package and competency programme were perceived as valuable and beneficial. Hands-on-practice was perceived as the most important form of education and ventilator settings as the most important topic. Multivariate analysis determined that older age was independently associated with not completing the self-directed learning package (AOR 0.20, 95% CI 0.04, 0.93). For the competency programme, 4-6 years intensive care experience was independently associated with completion (AOR 17, 95% CI 1.7, 165) and part-time employment was associated with non-completion (AOR 0.23, 95% CI 0.08, 0.68). CONCLUSION: Registered nurses are commencing their ICU experience with limited knowledge of invasive MV therefore the education provided within the ICU workplace becomes fundamental to safe and effective practice. The perception of continuing education by ICU nurses from this research is positive regardless of level of ICU experience and may influence the type of continuing education on invasive MV provided to ICU nurses in the future, not only in the ICU involved in this study, but other units throughout Australia.

Integrating and extending cohort studies: lessons from the eXtending Treatments, Education and Networks in Depression (xTEND) study.

BACKGROUND: Epidemiologic studies often struggle to adequately represent populations and outcomes of interest. Differences in methodology, data analysis and research questions often mean that reviews and synthesis of the existing literature have significant limitations. The current paper details our experiences in combining individual participant data from two existing cohort studies to address questions about the influence of social factors on health outcomes within a representative sample of urban to remote areas of Australia. The eXtending Treatments, Education and Networks in Depression study involved pooling individual participant data from the Australian Rural Mental Health Study (T0 N = 2639) and the Hunter Community Study (T0 N = 3253) as well as conducting a common three-year follow-up phase (T1 N = 3513). Pooling these data extended the capacity of these studies by: enabling research questions of common interest to be addressed; facilitating the harmonization of baseline measures; permitting investigation of a range of psychosocial, physical and contextual factors over time; and contributing to the development and implementation of targeted interventions for persons experiencing depression and alcohol issues. DISCUSSION: The current paper describes the rationale, challenges encountered, and solutions devised by a project aiming to maximise the benefits derived from existing cohort studies. We also highlight opportunities for such individual participant data analyses to assess common assumptions in research synthesis, such as measurement invariance, and opportunities for extending ongoing cohorts by conducting a common follow-up phase. SUMMARY: Pooling individual participant data can be a worthwhile venture, particularly where adequate representation is beyond the scope of existing research, where the effects of interest are small though important, where events are of relatively low frequency or rarely observed, and where issues are of immediate regional or national interest. Benefits such as these can enhance the utility of existing projects and strengthen requests for further research funding.

Construct validity of the Assessment of Quality of Life - 6D (AQoL-6D) in community samples.

BACKGROUND: The Assessment of Quality of Life - 6D scale (AQoL-6D) is a self-report instrument designed to provide a sensitive multidimensional evaluation of health related quality of life. The current paper assesses the construct, concurrent and convergent validity of the AQoL-6D in a combined longitudinal population sample drawn from across urban, regional and remote areas of Australia. METHODS: The AQoL-6D was administered within the Hunter Community Study and the Australian Rural Mental Health Study over time (mean years lag = 3.90, SD = 1.30). Observations with sufficient data were used to confirm the construct validity of the AQoL-6D domains and higher-order structure using confirmatory factor analyses (CFA, N = 7915). The stability of this structure across cohorts and over time was assessed using multi-group CFA. Additionally, the concurrent validity (against the SF-36) and convergent validity of AQoL-6D domains and factors were assessed. RESULTS: The construct validity of the AQoL-6D domains was considered satisfactory. Two higher-order factors, representing the physical and psychological components of quality of life were identified (CFA model fit: RMSEA = .07, SRMR = .03; TLI = .96, CFI = .98). These factors displayed group and temporal invariance, as well as concurrent and convergent validity against a range of measures. Recommendations for the derivation of summary scores are provided, together with a provisional set of norms. CONCLUSIONS: The AQoL-6D is a useful tool for assessing quality of life impairment in epidemiological cohort studies, both cross-sectionally and over time. It displays appropriate levels of construct, concurrent and convergent validity. Conceptualisation of higher-order factors as representing the physical and psychological aspects of quality of life impairment may increase the sensitivity and appeal of the AQoL-6D, particularly for studies examining predictors of and changes in social and psychological outcomes.

Quality of life impact of cardiovascular and affective conditions among older residents from urban and rural communities.

BACKGROUND: The demographic, health and contextual factors associated with quality of life impairment are investigated in older persons from New South Wales, Australia. We examine the impact of cardiovascular and affective conditions on impairment and the potential moderating influence of comorbidity and remoteness. METHODS: Data from persons aged 55 and over were drawn from two community cohorts sampling from across urban to very remote areas. Hierarchical linear regressions were used to assess: 1) the impact of cardiovascular and affective conditions on physical and psychological quality of life impairment; and 2) any influence of remoteness on these effects (N = 4364). Remoteness was geocoded to participants at the postal code level. Secondary data sources were used to examine the social capital and health service accessibility correlates of remoteness. RESULTS: Physical impairment was consistently associated with increased age, male gender, lower education, being unmarried, retirement, stroke, heart attack/angina, depression/anxiety, diabetes, hypertension, current obesity and low social support. Psychological impairment was consistently associated with lower age, being unmarried, stroke, heart attack/angina, depression/anxiety and low social support. Remoteness tended to be associated with lower psychological impairment, largely reflecting overall urban versus rural differences. The impacts of cardiovascular and affective conditions on quality of life were not influenced by remoteness. Social capital increased and health service accessibility decreased with remoteness, though no differences between outer-regional and remote/very remote areas were observed. Trends suggested that social capital was associated with lower psychological impairment and that the influence of cardiovascular conditions and social capital on psychological impairment was greater for persons with a history of affective conditions. The beneficial impact of social capital in reducing psychological impairment was more marked for those experiencing financial difficulty. CONCLUSIONS: Cardiovascular and affective conditions are key determinants of physical and psychological impairment. Persons affected by physical-psychological comorbidity experience greater psychological impairment. Social capital is associated with community remoteness and may ameliorate the psychological impairment associated with affective disorders and financial difficulties. The use of classifications of remoteness that are sensitive to social and health service accessibility determinants of health may better inform future investigations into the impact of context on quality of life outcomes.

Longitudinal course and predictors of suicidal ideation in a rural community sample.

OBJECTIVE: Suicide rates in rural Australia are higher than in urban areas. No existing research has explored the long-term patterns and predictors of change in suicidal ideation within rural areas. This report uses longitudinal data and multiple time points to determine predictors of the trajectory of suicidal ideation in rural Australia. METHOD: Participants in the Australian Rural Mental Health Study (ARMHS) completed self-report surveys at baseline, 12 and 36 months, reporting their psychological and social well-being, and suicidal ideation. Generalised linear mixed models explored these factors as correlates and predictors of suicidal ideation across 3 years using multiple data points. RESULTS: A total of 2135 participants completed at least one wave of ARMHS, and hence were included in the current analysis. Overall, 8.1% reported suicidal ideation during at least one study wave, 76% of whom reported suicidal ideation intermittently rather than consistently across waves. Across the three time points, suicidal ideation was significantly associated with higher psychological distress (OR 1.30, 95% CI 1.23 to 1.37), neuroticism (OR 1.15, 95% CI 1.04 to 1.27), and availability of support (OR 0.80, 95% CI 0.69 to 0.92), with a non-significant association with unemployment (OR 1.73, 95% CI 0.93 to 3.24) even after controlling for the effects of perceived financial hardship. Future suicidal ideation was significantly predicted by distress (OR 1.16, 95% CI 1.09 to 1.23) and neuroticism (OR 1.17, 95% CI 1.03 to 1.32), with a non-significant association with unemployment (OR 2.11, 95% CI 0.41 to 2.27). Predictive effects for marital status, social networks, sense of community and availability of support did not remain significant in the full multivariate analysis. CONCLUSIONS: Fluctuations in suicidal ideation are common, and may be associated with changes in psychological and social well-being. Public health strategies, focusing on encouraging help-seeking among those with higher psychological distress, lower social support, and unstable or absent employment opportunities, may be a useful long-term initiative to reduce the prevalence of suicidal ideation in the general rural community.

Factors associated with reported service use for mental health problems by residents of rural and remote communities: cross-sectional findings from a baseline survey.

BACKGROUND: The patterns of health service use by rural and remote residents are poorly understood and under-represented in national surveys. This paper examines professional and non-professional service use for mental health problems in rural and remote communities in Australia. METHODS: A stratified random sample of adults was drawn from non-metropolitan regions of New South Wales, Australia as part of a longitudinal population-based cohort. One-quarter (27.7%) of the respondents were from remote or very remote regions. The socio-demographic, health status and service utilization (professional and non-professional) characteristics of 2150 community dwelling residents are described. Hierarchical logistic regressions were used to identify cross-sectional associations between socio-demographic, health status and professional and non-professional health service utilization variables. RESULTS: The overall rate of professional contacts for mental health problems during the previous 12 months (17%) in this rural population exceeded the national rate (11.9%). Rates for psychologists and psychiatrists were similar but rates for GPs were higher (12% vs. 8.1%). Non-professional contact rates were 12%. Higher levels of help seeking were associated with the absence of a partner, poorer finances, severity of mental health problems, and higher levels of adversity. Remoteness was associated with lower utilization of non-professional support. A Provisional Service Need Index was devised, and it demonstrated a broad dose-response relationship between severity of mental health problems and the likelihood of seeking any professional or non-professional help. Nevertheless, 47% of those with estimated high service need had no contact with professional services. CONCLUSIONS: An examination of self-reported patterns of professional and non-professional service use for mental health problems in a rural community cohort revealed relatively higher rates of general practitioner attendance for such problems compared with data from metropolitan centres. Using a measure of Provisional Service Need those with greater needs were more likely to access specialist services, even in remote regions, although a substantial proportion of those with the highest service need sought no professional help. Geographic and financial barriers to service use were identified and perception of service adequacy was relatively low, especially among those with the highest levels of distress and greatest adversity.

Feasibility of biomarkers to measure stress, burnout and fatigue in emergency nurses: a cross-sectional study.

INTRODUCTION: Retaining nurses in the workforce is an urgent concern in healthcare. Emergency nurses report high levels of stress and burnout, however, there is no gold standard of how to measure these responses. This study aims to measure stress, burnout, and fatigue in emergency nurses using biomarkers and psychometric instruments. Biomarkers will be used to better understand nurses' levels of stress and burnout and to assess the feasibility of using biomarkers as a viable stress measurement tool in a real-world setting. METHODS AND ANALYSIS: A two stage cross-sectional design to measure stress, burnout and fatigue in emergency nurses while they work is proposed. All registered and enrolled nurses working in the emergency department from four hospitals in Australia will be invited to participate. Validated psychometric tools will be used in stage 1 to measure depression, anxiety, acute stress, chronic stress, burnout and fatigue. Biomarkers comprising hair cortisol, saliva alpha amylase and heart rate variability will be collected as an objective measure of stress and burnout in stage 2 over one working shift per participant. Written consent will be sought for stage 2 where nurses will provide one hair sample, wear a heart rate sensor and be asked to collect their saliva at three different time points of one shift. Data analysis will measure the domains of acute stress, chronic stress and burnout and explore relationships and correlation between psychometric measures and biomarkers. ETHICS AND DISSEMINATION: Ethics approval obtained from the Human Research Ethics Committee of the Hunter New England Local Health District (approval number: HREC/2020/ETH01684) and University of Newcastle HREC (H-2022-0169). Results will be reported in peer-reviewed publications using the Strengthening the Reporting of Observational Studies in Epidemiology guidelines. Public dissemination will occur by presenting at conferences and to the participating local health district.

Contributors to suicidality in rural communities: beyond the effects of depression.

BACKGROUND: Rural populations experience a higher suicide rate than urban areas despite their comparable prevalence of depression. This suggests the identification of additional contributors is necessary to improve our understanding of suicide risk in rural regions. Investigating the independent contribution of depression, and the impact of co-existing psychiatric disorders, to suicidal ideation and suicide attempts in a rural community sample may provide clarification of the role of depression in rural suicidality. METHODS: 618 participants in the Australian Rural Mental Health Study completed the Composite International Diagnostic Interview, providing assessment of lifetime suicidal ideation and attempts, affective disorders, anxiety disorders and substance-use disorders. Logistic regression analyses explored the independent contribution of depression and additional diagnoses to suicidality. A receiver operating characteristic (ROC) analysis was performed to illustrate the benefit of assessing secondary psychiatric diagnoses when determining suicide risk. RESULTS: Diagnostic criteria for lifetime depressive disorder were met by 28% (174) of the sample; 25% (154) had a history of suicidal ideation. Overall, 41% (63) of participants with lifetime suicidal ideation and 34% (16) of participants with a lifetime suicide attempt had no history of depression. When lifetime depression was controlled for, suicidal ideation was predicted by younger age, being currently unmarried, and lifetime anxiety or post-traumatic stress disorder. In addition to depression, suicide attempts were predicted by lifetime anxiety and drug use disorders, as well as younger age; being currently married and employed were significant protective factors. The presence of comorbid depression and PTSD significantly increased the odds of reporting a suicide attempt above either of these conditions independently. CONCLUSIONS: While depression contributes significantly to suicidal ideation, and is a key risk factor for suicide attempts, other clinical and demographic factors played an important role in this rural sample. Consideration of the contribution of factors such as substance use and anxiety disorders to suicidal ideation and behaviours may improve our ability to identify individuals at risk of suicide. Acknowledging the contribution of these factors to rural suicide may also result in more effective approaches for the identification and treatment of at-risk individuals.
