    Trajectories of intimate partner violence (IPV) in a primary care cohort of women with depressive symptoms
    Hegarty, K ; Densley, K ; Gilchrist, G ; Elliott, P ; Gunn, J (Bristol University Press, 2023-02)
    Aims: To assess trajectories of women’s experience of intimate partner violence (IPV) over time, and baseline risk factors and associated four-year outcomes for different trajectories. Design: A cohort study of 548 women with depressive symptoms, attending primary care appointments, were surveyed annually for four years. Secondary analysis was undertaken using growth mixture modelling to generate IPV trajectories. Analyses of associations of these generated classes of IPV with hypothesised baseline and four-year measures were undertaken. Results: At baseline, 42% (231) women experienced IPV in past 12 months. Five-class IPV trajectory model showed five groups over time: consistently ‘high IPV’ (5%, n=28), ‘some IPV’ (14%, n=77), ‘minimal IPV’ (9%, n=52), ‘decreasing IPV’ (11%, n=62), and ‘no IPV’ (60%, n=329). Baseline differences showed women in ‘high’ and ‘some’ group had more childhood abuse, low income and poor mental health compared to ‘minimal’ or ‘no IPV’ groups. At four years, ‘decreasing IPV’ group was aligned with ‘minimal/no IPV’ groups on mental health, quality of life and social support measures. Conclusion: Women exhibited different trajectories of IPV over time with high burden of mental health problems, except for when IPV decreases. Clinical identification of IPV and tailoring of responses to decrease exposure to IPV is warranted to reduce disease burden.

    Coe, A ; Bibb, J ; Kritharidis, R ; O'Mara, M ; Lautman, R ; Densley, K ; Kovarik, S ; Kaylor-Hughes, C ; Lewis, M ; Palmer, VJ (Elsevier BV, 2023-12-15)
    OBJECTIVE: To evaluate a facilitated, 90-min session, delivered for four weeks, Online Carer Wellbeing and Connection Program in Victoria, Australia. METHODS: One hundred and three carers took part in the evaluation. Eighty-six completed both pre- and post-program surveys evaluating program impacts on psychological distress, perceived loneliness, and social support. Qualitative interviews were conducted (n = 76) post-program for experiential data. FINDINGS: Paired samples t-tests showed significant decreases between pre- and post-program for psychological distress (M = 25.10, SD = 7.08; M = 22.00, SD = 6.57; t(85) = 4.88, p = 0.000), perceived loneliness (M = 6.69, SD = 1.89; M = 6.14, SD = 1.76; t(85) = 3.45, p = 0.000) and perceived social support (M = 8.31, SD = 2.48; M = 8.83, SD = 2.21; t(85) = -2.54, p = 0.013). Thematic analysis identified positive experiences and the mechanisms of action (or the ingredients for program success) as: 1. Delivery by a trained facilitator; 2. Provision of respite for person being cared for during meetings; 3. Technical assistance; 4. Online modality; 5. Inclusivity; 6. Diversity of experience; 7. Shared understanding; 8. Safety; 9. Emotional release; 10. Reflection, and; 11. Self-care practices. INNOVATION: A model illustrating the mechanisms of action based on the findings of the mixed-methods evaluation is presented to support wider implementation and translation. CONCLUSION: The online program effectively reduced psychological distress and loneliness and improved carer wellbeing.

    Economic evaluation of the Target-D platform to match depression management to severity prognosis in primary care: A within-trial cost-utility analysis
    Lee, YY ; Mihalopoulos, C ; Chatterton, ML ; Fletcher, S ; Chondros, P ; Densley, KL ; Murray, EK ; Dowrick, C ; Coe, AJ ; Hegarty, KM ; Davidson, S ; Wachtler, C ; Palmer, V ; Gunn, J ; Durand-Zaleski, I (PUBLIC LIBRARY SCIENCE, 2022)
    BACKGROUND: Target-D, a new person-centred e-health platform matching depression care to symptom severity prognosis (minimal/mild, moderate or severe) has demonstrated greater improvement in depressive symptoms than usual care plus attention control. The aim of this study was to evaluate the cost-effectiveness of Target-D compared to usual care from a health sector and partial societal perspective across 3-month and 12-month follow-up. METHODS AND FINDINGS: A cost-utility analysis was conducted alongside the Target-D randomised controlled trial; which involved 1,868 participants attending 14 general practices in metropolitan Melbourne, Australia. Data on costs were collected using a resource use questionnaire administered concurrently with all other outcome measures at baseline, 3-month and 12-month follow-up. Intervention costs were assessed using financial records compiled during the trial. All costs were expressed in Australian dollars (A$) for the 2018-19 financial year. QALY outcomes were derived using the Assessment of Quality of Life-8D (AQoL-8D) questionnaire. On a per person basis, the Target-D intervention cost between $14 (minimal/mild prognostic group) and $676 (severe group). Health sector and societal costs were not significantly different between trial arms at both 3 and 12 months. Relative to a A$50,000 per QALY willingness-to-pay threshold, the probability of Target-D being cost-effective under a health sector perspective was 81% at 3 months and 96% at 12 months. From a societal perspective, the probability of cost-effectiveness was 30% at 3 months and 80% at 12 months. CONCLUSIONS: Target-D is likely to represent good value for money for health care decision makers. Further evaluation of QALY outcomes should accompany any routine roll-out to assess comparability of results to those observed in the trial. This trial is registered with the Australian New Zealand Clinical Trials Registry (ACTRN12616000537459).

    The CORE study-An adapted mental health experience codesign intervention to improve psychosocial recovery for people with severe mental illness: A stepped wedge cluster randomized-controlled trial
    Palmer, VJ ; Chondros, P ; Furler, J ; Herrman, H ; Pierce, D ; Godbee, K ; Densley, K ; Gunn, JM (WILEY, 2021-12)
    BACKGROUND: Mental health policies outline the need for codesign of services and quality improvement in partnership with service users and staff (and sometimes carers), and yet, evidence of systematic implementation and the impacts on healthcare outcomes is limited. OBJECTIVE: The aim of this study was to test whether an adapted mental health experience codesign intervention to improve recovery-orientation of services led to greater psychosocial recovery outcomes for service users. DESIGN: A stepped wedge cluster randomized-controlled trial was conducted. SETTING AND PARTICIPANTS: Four Mental Health Community Support Services providers, 287 people living with severe mental illnesses, 61 carers and 120 staff were recruited across Victoria, Australia. MAIN OUTCOME MEASURES: The 24-item Revised Recovery Assessment Scale (RAS-R) measured individual psychosocial recovery. RESULTS: A total of 841 observations were completed with 287 service users. The intention-to-treat analysis found RAS-R scores to be similar between the intervention (mean = 84.7, SD= 15.6) and control (mean = 86.5, SD= 15.3) phases; the adjusted estimated difference in the mean RAS-R score was -1.70 (95% confidence interval: -3.81 to 0.40; p = .11). DISCUSSION: This first trial of an adapted mental health experience codesign intervention for psychosocial recovery outcomes found no difference between the intervention and control arms. CONCLUSIONS: More attention to the conditions that are required for eight essential mechanisms of change to support codesign processes and implementation is needed. PATIENT AND PUBLIC INVOLVEMENT: The State consumer (Victorian Mental Illness Awareness Council) and carer peak bodies (Tandem representing mental health carers) codeveloped the intervention. The adapted intervention was facilitated by coinvestigators with lived-experiences who were coauthors for the trial and process evaluation protocols, the engagement model and explanatory model of change for the trial.

    Matching depression management to severity prognosis in primary care: results of the Target-D randomised controlled trial
    Fletcher, S ; Chondros, P ; Densley, K ; Murray, E ; Dowrick, C ; Coe, A ; Hegarty, K ; Davidson, S ; Wachtler, C ; Mihalopoulos, C ; Lee, YY ; Chatterton, ML ; Palmer, VJ ; Gunn, J (ROYAL COLL GENERAL PRACTITIONERS, 2021-02)
    BACKGROUND: Mental health treatment rates are increasing, but the burden of disease has not reduced. Tools to support efficient resource distribution are required. AIM: To investigate whether a person-centred e-health (Target-D) platform matching depression care to symptom severity prognosis can improve depressive symptoms relative to usual care. DESIGN AND SETTING: Stratified individually randomised controlled trial in 14 general practices in Melbourne, Australia, from April 2016 to February 2019. In total, 1868 participants aged 18-65 years who had current depressive symptoms; internet access; no recent change to antidepressant; no current antipsychotic medication; and no current psychological therapy were randomised (1:1) via computer-generated allocation to intervention or usual care. METHOD: The intervention was an e-health platform accessed in the GP waiting room, comprising symptom feedback, priority-setting, and prognosis-matched management options (online self-help, online guided psychological therapy, or nurse-led collaborative care). Management options were flexible, neither participants nor staff were blinded, and there were no substantive protocol deviations. The primary outcome was depressive symptom severity (9-item Patient Health Questionnaire [PHQ-9]) at 3 months. RESULTS: In intention to treat analysis, estimated between- arm difference in mean PHQ-9 scores at 3 months was -0.88 (95% confidence interval [CI] = -1.45 to -0.31) favouring the intervention, and -0.59 at 12 months (95% CI = -1.18 to 0.01); standardised effect sizes of -0.16 (95% CI = -0.26 to -0.05) and -0.10 (95% CI = -0.21 to 0.002), respectively. No serious adverse events were reported. CONCLUSION: Matching management to prognosis using a person-centred e-health platform improves depressive symptoms at 3 months compared to usual care and could feasibly be implemented at scale. Scope exists to enhance the uptake of management options.

    Clinical efficacy of a Decision Support Tool (Link-me) to guide intensity of mental health care in primary practice: a pragmatic stratified randomised controlled trial
    Fletcher, S ; Spittal, MJ ; Chondros, P ; Palmer, VJ ; Chatterton, ML ; Densley, K ; Potiriadis, M ; Harris, M ; Bassilios, B ; Burgess, P ; Mihalopoulos, C ; Pirkis, J ; Gunn, J (ELSEVIER SCI LTD, 2021-03)
    BACKGROUND: The volume and heterogeneity of mental health problems that primary care patients present with is a substantial challenge for health systems, and both undertreatment and overtreatment are common. We developed Link-me, a patient-completed Decision Support Tool, to predict severity of depression or anxiety, identify priorities, and recommend interventions. In this study, we aimed to examine if Link-me reduces psychological distress among individuals predicted to have minimal/mild or severe symptoms of anxiety or depression. METHODS: In this pragmatic stratified randomised controlled trial, adults aged 18-75 years reporting depressive or anxiety symptoms or use of mental health medication were recruited from 23 general practices in Australia. Participants completed the Decision Support Tool and were classified into three prognostic groups (minimal/mild, moderate, severe), and those in the minimal/mild and severe groups were eligible for inclusion. Participants were individually and randomly assigned (1:1) by a computer-generated allocation sequence to receive either prognosis-matched care (intervention group) or usual care plus attention control (control group). Participants were not blinded but intervention providers were only notified of those allocated to the intervention group. Outcome assessment was blinded. The primary outcome was the difference in the change in scores between the intervention and control group, and within prognostic groups, on the 10-item Kessler Psychological Distress Scale at 6 months post randomisation. The trial was registered on the Australian and New Zealand Clinical Trials Registry, ACTRN12617001333303. OUTCOMES: Between Nov 21, 2017, and Oct 31, 2018, 24 616 patients were invited to complete the eligibility screening survey. 1671 of these patients were included and randomly assigned to either the intervention group (n=834) or the control group (n=837). Prognosis-matched care was associated with greater reductions in psychological distress than usual care plus attention control at 6 months (p=0·03), with a standardised mean difference (SMD) of -0·09 (95% CI -0·17 to -0·01). This reduction was also seen in the severe prognostic group (p=0·003), with a SMD of -0·26 (-0·43 to -0·09), but not in the minimal/mild group (p=0·73), with a SMD of 0·04 (-0·17 to 0·24). In the complier average causal effect analysis in the severe prognostic group, differences were larger among those who received some or all aspects of the intervention (SMD range -0·58 to -1·15). No serious adverse effects were recorded. INTERPRETATION: Prognosis-based matching of interventions reduces psychological distress in patients with anxiety or depressive symptoms, particularly in those with severe symptoms, and is associated with better outcomes when patients access the recommended treatment. Optimisation of the Link-me approach and implementation into routine practice could help reduce the burden of disease associated with common mental health conditions such as anxiety and depression.

    Rapid Design and Delivery of an Experience-Based Co-designed Mobile App to Support the Mental Health Needs of Health Care Workers Affected by the COVID-19 Pandemic: Impact Evaluation Protocol (Preprint)
    Lewis, M ; Palmer, VJ ; Kotevski, A ; Densley, K ; O'Donnell, ML ; Johnson, C ; Wohlgezogen, F ; Gray, K ; Robins-Browne, K ; Burchill, L (JMIR Publications, 2020-12-02)
    BACKGROUND

    The COVID-19 pandemic has highlighted the importance of health care workers’ mental health and well-being for the successful function of the health care system. Few targeted digital tools exist to support the mental health of hospital-based health care workers, and none of them appear to have been led and co-designed by health care workers.

    OBJECTIVE

    RMHive is being led and developed by health care workers using experience-based co-design (EBCD) processes as a mobile app to support the mental health challenges posed by the COVID-19 pandemic to health care workers. We present a protocol for the impact evaluation for the rapid design and delivery of the RMHive mobile app.

    METHODS

    The impact evaluation will adopt a mixed methods design. Qualitative data from photo interviews undertaken with up to 30 health care workers and semistructured interviews conducted with up to 30 governance stakeholders will be integrated with qualitative and quantitative user analytics data and user-generated demographic and mental health data entered into the app. Analyses will address three evaluation questions related to engagement with the mobile app, implementation and integration of the app, and the impact of the app on individual mental health outcomes. The design and development will be described using the Mobile Health Evidence Reporting and Assessment guidelines. Implementation of the app will be evaluated using normalization process theory to analyze qualitative data from interviews combined with text and video analysis from the semistructured interviews. Mental health impacts will be assessed using the total score of the 4-item Patient Health Questionnaire (PHQ4) and subscale scores for the 2-item Patient Health Questionnaire for depression and the 2-item Generalized Anxiety Scale for anxiety. The PHQ4 will be completed at baseline and at 14 and 28 days.

    RESULTS

    The anticipated average use period of the app is 30 days. The rapid design will occur over four months using EBCD to collect qualitative data and develop app content. The impact evaluation will monitor outcome data for up to 12 weeks following hospital-wide release of the minimal viable product release. The study received funding and ethics approvals in June 2020. Outcome data is expected to be available in March 2021, and the impact evaluation is expected to be published mid-2021.

    CONCLUSIONS

    The impact evaluation will examine the rapid design, development, and implementation of the RMHive app and its impact on mental health outcomes for health care workers. Findings from the impact evaluation will provide guidance for the integration of EBCD in rapid design and implementation processes. The evaluation will also inform future development and rollout of the app to support the mental health needs of hospital-based health care workers more widely.

    The assertive cardiac care trial: A randomised controlled trial of a coproduced assertive cardiac care intervention to reduce absolute cardiovascular disease risk in people with severe mental illness in the primary care setting
    Lewis, M ; Chondros, P ; Mihalopoulos, C ; Lee, YY ; Gunn, JM ; Harvey, C ; Furler, J ; Osborn, D ; Castle, D ; Davidson, S ; Jayaram, M ; Kenny, A ; Nelson, MR ; Morgan, VA ; Harrap, S ; McKenzie, K ; Potiriadis, M ; Densley, K ; Palmer, VJ (ELSEVIER SCIENCE INC, 2020-10)
    BACKGROUND: Cardiovascular disease (CVD) accounts for 40% of the excess mortality identified in people with severe mental illness (SMI). Modifiable CVD risk factors are higher and can be exacerbated by the cardiometabolic impact of psychotropic medications. People with SMI frequently attend primary care presenting a valuable opportunity for early identification, prevention and management of cardiovascular health. The ACCT Healthy Hearts Study will test a coproduced, nurse-led intervention delivered with general practitioners to reduce absolute CVD risk (ACVDR) at 12 months compared with an active control group. METHODS/DESIGN: ACCT is a two group (intervention/active control) individually randomised (1:1) controlled trial (RCT). Assessments will be completed baseline (pre-randomisation), 6 months, and 12 months. The primary outcome is 5-year ACVDR measured at 12 months. Secondary outcomes include 6-month ACVDR; and blood pressure, lipids, HbA1c, BMI, quality of life, physical activity, motivation to change health behaviour, medication adherence, alcohol use and hospitalisation at 6 and 12 months. Linear mixed-effects regression will estimate mean difference between groups for primary and secondary continuous outcomes. Economic cost-consequences analysis will be conducted using quality of life and health resource use information and routinely collected government health service use and medication data. A parallel process evaluation will investigate implementation of the intervention, uptake and outcomes. DISCUSSION: ACCT will deliver a coproduced and person-centred, guideline level cardiovascular primary care intervention to a high need population with SMI. If successful, the intervention could lead to the reduction of the mortality gap and increase opportunities for meaningful social and economic participation.

    St John's wort use in Australian general practice patients with depressive symptoms: their characteristics and use of other health services
    Pirotta, M ; Densley, K ; Forsdike, K ; Carter, M ; Gunn, J (BIOMED CENTRAL LTD, 2014-06-26)
    BACKGROUND: While depression is frequently managed by general practitioners, often patients self-manage these symptoms with alternative therapies, including St John's wort (SJW). We tested whether use of SJW was associated with different patterns of conventional and complementary health service use, strategies used for management of depression, or user dissatisfaction with or lack of trust in their general practitioner or clinic overall. METHODS: Secondary analysis of data collected from an Australian population screened for a longitudinal cohort study of depression. Main outcome measures were CES-D for depressive symptoms, satisfaction with their general practitioner (GPAQ), Trust in Physician scale, self-report of health services usage and strategies used to manage depression, stress or worries. RESULTS: Response rate was 7667/17,780 (43.1%). Of these, 4.3% (320/7,432) had used SJW in the past 12 months (recent 'SJW users'). SJW users were significantly more likely to be depressed and to have a higher CES-D score. There were no statistically significant differences between recent SJW users and non-SJW users in satisfaction with their general practice or in trust in their general practitioner (GP) when adjusted for multiple factors. SJW users were significantly more likely to use all health services, whether conventional or complementary, as well as other strategies used for mental health care. SJW users were also more likely to consider themselves the main carer for their depression. CONCLUSIONS: Primary care attendees with symptoms of depression who use SJW appear not to be rejecting conventional medicine. Rather, they may be proactive care seekers who try both conventional and complementary strategies to manage their depressive symptoms. If GPs enquire and find that their depressed patients are using SJW, this may indicate that they might explore for unrelieved symptoms of depression and also consider the issue of potential for interactions between SJW and other medicines.
