Risk and Protective Factors for Medically Serious Suicide Attempts: A Comparison of Hospital-Based with Population-Based Samples of Young Adults:

Objective: To investigate risk and protective factors for medically serious suicide attempts among young Australian adults. Method: The study used a case–control design. A clinical sample of 18–24 year olds was recruited via the emergency department of a large public hospital following a suicide attempt (n=95) and was compared to a sample of 18–24 year olds who participated in a population-based survey (n=380). Results: Risk factors for medically serious suicide attempts included early school leaving, parental divorce (males only), distress due to problems with parents (females only), distress due to problems with friends, distress due to the break-up of a romantic relationship, tobacco use, high alcohol use, current depressive symptomatology and a previous diagnosis of depression. Protective factors included social connectedness, problem-solving confidence and locus of control. There was a trend for social connectedness to be more protective among those with high rather than low levels of depressive symptomatology, and among smokers rather than non-smokers. Conclusions: Results are discussed in terms of designing evidence-based suicide prevention activities for young adults.

Hospital admissions, emergency department utilisation and patient activation for self-management among people with diabetes

AIMS To assess the relationship between patient activation for self-management and admissions to hospital or attendances at emergency departments among people with diabetes, after controlling for other known associations. METHODS Patients were randomly selected from Australias National Diabetes Services Scheme and invited to participate in the Living with Diabetes Study, which is a longitudinal survey providing a comprehensive examination of health care utilisation, well-being and disease progression. Data was collected for 3951 participants. RESULTS Outcome events were defined as 1 or more hospitalization and 1 or more visits to an emergency department in the preceding 12 months. Logistic regression analyses showed six variables remained significantly associated with both outcomes: age, income, disease duration and severity, current depression and PAM stage. Patients at PAM stage 1 were 1.4 times more likely to be hospitalised (p=0.023) and 1.3 times more likely to have visited emergency (p=0.049) compared to those at stage 4. CONCLUSIONS Low levels of activation are associated with higher utilisation of hospital resources even after controlling for relevant factors such as disease severity and co-morbid depression. Most will be gained by moving patients from PAM stage 1 to a higher level of activation.

Living with diabetes: rationale, study design and baseline characteristics for an Australian prospective cohort study

BackgroundDiabetes mellitus is a major global public health threat. In Australia, as elsewhere, it is responsible for a sizeable portion of the overall burden of disease, and significant costs. The psychological and social impact of diabetes on individuals with the disease can be severe, and if not adequately addressed, can lead to the worsening of the overall disease picture. The Living With Diabetes Study aims to contribute to a holistic understanding of the psychological and social aspects of diabetes mellitus.Methods/DesignThe Living With Diabetes Study is a 5-year prospective cohort study, based in Queensland, Australia. The first wave of data, which was collected via a mailed self-report survey, was gathered in 2008, with annual collections thereafter. Measurements include: demographic, lifestyle, health and disease characteristics; quality of life (EQ-5D, ADDQoL); emotional well-being (CES-D, LOT-R, ESSI); disease self-management (PAM); and health-care utilisation and patient-assessed quality of care (PACIC). 29% of the 14,439 adults who were invited to participate in the study agreed to do so, yielding a sample size of 3,951 people.DiscussionThe data collected by the Living With Diabetes Study provides a good representation of Australians with diabetes to follow over time in order to better understand the natural course of the illness. The study has potential to further illuminate, and give a comprehensive picture of the psychosocial implications of living with diabetes. Data collection is ongoing.

The Audit of Diabetes-Dependent Quality of Life 19 (ADDQoL): feasibility, reliability and validity in a population-based sample of Australian adults

PurposeThis study aims to analyse the psychometric properties of the most recent 19 item version of the Audit of Diabetes-Dependent Quality of Life (ADDQoL) in a large, population-based sample of adults living in Australia.MethodsA total of 3,951 people living with diabetes completed the ADDQoL as part of the Living With Diabetes Study. Data analysis investigated the feasibility of using the ADDQoL in a large, population-based survey; internal consistency; adherence to a single-factor structure; and convergent/discriminant validity.ResultsData support the feasibility of using the ADDQoL in population-based survey research. Although a strict single-factor structure for the ADDQoL was not demonstrated, the results overall support an interpretation of essential unidimensionality. A validation matrix provides support for the convergent and divergent validity of the measure, as does the ADDQoL’s ability to discriminate between respondents based on insulin dependence and complications.ConclusionsThe ADDQoL has good psychometric properties and provides clinicians and researchers with a useful tool for comprehensively assessing quality of life in adults with diabetes.

Patterns and determinants of influenza and pneumococcal immunisation among adults with chronic disease living in Queensland, Australia

Using findings from a random, computer assisted telephone survey of households, this paper examines influenza and pneumococcal immunisation coverage and predictors of immunisation in 2203 adults with asthma, diabetes or a cardiovascular condition living in Queensland, Australia. 47% and 31% of high-risk persons were immunised against influenza and pneumococcus respectively. Immunisation coverage varied across chronic conditions and increased with age, being significantly higher for those aged 65 years and older and consequently eligible for free vaccination. Poor self reported health status was an independent predictor of pneumococcal vaccination status for people with asthma, diabetes or a cardiovascular condition; however it was only an independent predictor of influenza immunisation status for people with diabetes. Extending free vaccination to all people at risk may increase immunisation rates for younger people with a chronic condition.

Mental health issues decrease diabetes-specific quality of life independent of glycaemic control and complications: findings from Australia’s living with diabetes cohort study

BackgroundWhile factors associated with health-related quality of life for people with chronic diseases including diabetes are well researched, far fewer studies have investigated measures of disease-specific quality of life. The purpose of this study is to assess the impact of complications and comorbidities on diabetes-specific quality of life in a large population-based cohort of type 2 diabetic patients.MethodsThe Living with Diabetes Study recruited participants from the National Diabetes Services Scheme in Australia. Data were collected via a mailed self-report questionnaire. Diabetes-specific quality of life was measured using the Audit of Diabetes-Dependent Quality of Life (ADDQoL) questionnaire. The analyses are for 3609 patients with type 2 diabetes. Regression models with adjustment for control variables investigated the association of complications and comorbidities with diabetes-specific quality of life. Next, the most parsimonious model for diabetes-specific quality of life after controlling for important covariates was examined.ResultsThe expected associations with better diabetes-specific quality of life were evident, such as increased income, not on insulin, better glycaemic control and older age. However, being single and having been diagnosed with cancer were also associated with better ADDQoL. Additionally, poorer diabetes-specific quality of life was strongly sensitive to the presence of diabetes complications and mental health conditions such as depression, anxiety and schizophrenia. These relationships persisted after adjustment for gender, age, duration of diabetes, treatment regimen, sampling region and other treatment and socio-demographic variables.ConclusionsA greater appreciation of the complexities of diabetes-specific quality of life can help tailor disease management and self-care messages given to patients. Attention to mental health issues may be as important as focusing on glycaemic control and complications. Therefore clinicians’ ability to identify and mange mental health issues and/or refer patients is critical to improving patients’ diabetes-specific quality of life.

Evaluation of a Suicide Prevention Training Program for Mental Health Services Staff

Training for health services staff often focuses on improving individual practitioner’s knowledge and skills, with less emphasis given to the broader organizational context, in particular those elements that support successful implementation of changes post-training. This paper compares the effectiveness of a standard training model for suicide prevention to an enhanced training model. The training involved the public mental health workforce throughout the State of Queensland, Australia and was developed in collaboration with the State health department and as such took place within a policy and practice context. The standard training involved participation in a one-day training workshop, which provided information on evidence-based suicide prevention strategies. The enhanced model took an organizational development approach and incorporated a focus on creating and strengthening networks to enhance the capacity of mental health service staff to undertake preventive strategies. Findings suggest that multi-component organizational approaches for suicide prevention produces benefits that should now be trialled through experimental approaches.

Patient Assessment of Chronic Illness Care (PACIC) in Type 2 Diabetes A Longitudinal Study

The Patient Assessment of Chronic Illness Care (PACIC) was designed to measure care congruent with several elements of the chronic care model (CCM), including self-management support and delivery system design. However, support for the a priori 5-subscale structure of the PACIC in previous research has been conflicting. Thus, we aim to investigate psychometric characteristics of the PACIC including the content and stability of its construct over time. A population-based prospective cohort study of patients with type 2 diabetes was conducted in Queensland, Australia, from 2008 (N = 3,761) to 2010 (N = 3,040). Participants completed annually the 20-item PACIC as well as measures of providers’ adherence to guideline-recommended self-management support activities. We used exploratory factor analysis to determine its factor structure and examined internal consistency as well as agreement between the PACIC at baseline with repeated measurements at follow-up after 1 and 2 years. We also determined a criterion-related validity using multinomial logistic regression to explore PACIC’s association with providers’ self-management support. A one-factor structure was deemed optimal according to our findings. High internal consistency and moderate agreement within the scales over time were observed. Higher PACIC scores predicted better providers’ self-management support. In conclusion, the PACIC is a reliable, valid, and reproducible instrument for assessment of diabetes care, and we recommend its promotion and use as a single scale rather than subscales as originally proposed.
