Effect of mood on long-term disability in younger stroke survivors: results from the Psychosocial Outcomes In StrokE (POISE) study.

BACKGROUND & PURPOSE: Anxiety and depression are common among stroke survivors, and their effect on long-term outcome remains unknown in those under 65 years of age. We investigated the association between early anxiety/depression after stroke and 12-month disability, and whether this is modified by sex. METHODS: The Psychosocial Outcomes In StrokE (POISE) study was a prospective observational cohort study that recruited 441 younger (< 65 years) stroke survivors ≤28 days of acute stroke. Anxiety and depression were assessed using the Hospital Anxiety and Depression Scale, and disability using the World Health Organization Disability Assessment Scale version II (WHODAS-II). Associations between baseline anxiety/depression, and disability at 12-months was tested using analysis of covariance. Subgroup analysis was conducted using interaction term. RESULTS: 92 (25%) had anxiety and 53 (14%) depression at baseline. Multivariable models showed significant association between baseline anxiety and 12-month disability (WHODAS-II score 15.24 vs. 11.49, p < .05). Those with anxiety had more impairment in 'cognition' (WHODAS-II score 18.26 vs. 8.71, p < .001), 'getting along' (WHODAS-II score 11.87 vs. 7.42, p < .05) and 'participation' (WHODAS-II score 22.37 vs. 15.92, p < .005) WHODAS-II. No significant relationship was found between baseline depression and long-term disability. There was no differential effect of anxiety by sex found in this study. CONCLUSIONS: Post-stroke anxiety has an adverse effect on disability at one year among young stroke survivors.

Qualitative study of psychosocial factors impacting on Aboriginal women's management of chronic disease.

BACKGROUND: Aboriginal women are frequently called upon to support their families and other community members. At times, such supporting roles can be burdensome for these women. Many Aboriginal women live with chronic conditions. We explored the ways in which the women's caring roles impacted on how they maintained their own health. METHODS: The aim of this manuscript is to explore the psychosocial factors associated with the management of health and chronic disease in Aboriginal women. An interpretive phenomenological approach was used for the analysis of 72 in-depth semi-structured interviews. These interviews were conducted in four community controlled Aboriginal health services, in urban, rural and remote settings, across two states and a territory in Australia. RESULTS: Women living with chronic disease experience multiple challenges while caring for family, such as intergenerational trauma, mental health issues relating to addiction, domestic and family violence and incarceration. When these women become ill, they also have to take care of themselves. These women provided informal and unfunded care in response to a range of complex family and community problems. This continuous caring for family affected the women's ability to maintain their health and manage their own chronic conditions. CONCLUSION: The caring roles and responsibilities Aboriginal women have in their community impact on their health. Aboriginal women provide much needed refuge and support to family and the wider community. Underfunded and over-burdened formal support services are not meeting the needs of many Aboriginal women. Improved culturally secure resources and social services are required within communities to support Aboriginal women to successfully manage their own health.

Development of a set of mobile phone text messages designed for prevention of recurrent cardiovascular events.

BACKGROUND: Supporting lifestyle change is an effective way of preventing recurrent events in people with cardiovascular disease (CVD). However, there is a need to develop innovative strategies that increase access to programmes for individuals at high risk of CVD. This study aimed to develop a bank of text messages designed to provide advice, motivation, and support for decreasing cardiovascular risk. DESIGN: Iterative development process with mixed methods METHODS: An initial bank of 120 text messages was drafted based on behaviour change techniques, guidelines, and input from clinicians and public health experts. A questionnaire was then administered to participants (n = 53) for evaluation of message content, usefulness, and language. To test the process of delivery, a pilot study was conducted using a specifically designed computer programme that delivered messages to multiple mobile phones according to a pre-specified schedule. Data were collected regarding message timing, delivery, and usefulness. RESULTS: In the qualitative questionnaire, 92% of participants found the messages easy to understand and 86% found the messages contained useful information. Positive feedback was also obtained from the pilot study. Based on these results, together with suggestions provided, several messages were reworded and an additional 44 were written. The need for semi-personalization was also identified and a random set of 103 individualized messages was created. CONCLUSIONS: A final bank of 137 mobile telephone text messages designed to support behaviour change and decrease cardiovascular risk have been developed through a multistep iterative process. This provides a scientific approach for future developers of health-related text messages.

imProving Outcomes after STroke clinical pilot trial protocol.

RATIONALE: One in three patients experience depression after stroke and this risk is consistent over time. A strategy to prevent depression that could be economically delivered to most stroke patients and ideally which also has a low likelihood of adverse events needs to be developed and evaluated. Aims POST aims to determine whether a simple intervention (postcards) prevents depression (Hospital Anxiety and Depression rating Scale, HADS depression subscale score > or =8) in patients with a recent stroke. Secondary end-points include reduced anxiety (HADS anxiety subscale score > or =8) and improved health-related quality of life in patients with a recent stroke. DESIGN: A single-centre randomised, double-blind, pilot trial to prevent depression in patients with a recent (within 8 weeks) stroke presenting to hospital. Patients will be enrolled over 12 months and randomised to receive three trial-specific assessments (baseline, 3- and 6-month assessments of mood, HRQoL and social functioning), or three trial-specific assessments plus a postcard sent centrally in a sealed envelope at 1, 2, 3, 4 and 5 months after discharge from hospital. Blinded follow-up telephone assessments will be conducted for both groups. STUDY OUTCOMES AND SAMPLE SIZE: For the primary end-point the POST trial will have 80% power to detect a relative risk of 0.4 given an incidence of depression of 30%. For the secondary aims POST has 90% power to detect a difference of 3 points on the HADS depression subscale (assuming a standard deviation of 6 points) between randomised groups. This includes an inflation factor of 15% to account for patients lost to follow-up. DISCUSSION: Evidence of efficacy will determine whether a multi-centre, international trial is warranted.

Interventions for treating depression after stroke.

BACKGROUND: Depressive and anxiety disorders following stroke are often undiagnosed or inadequately treated. This may reflect difficulties with the diagnosis of abnormal mood among older people with stroke-related disability, but may also reflect uncertainty about the effectiveness of such therapies in this setting. OBJECTIVES: To determine whether pharmacological, psychological, or electroconvulsive treatment (ECT) of depression in patients with stroke can improve outcome. SEARCH STRATEGY: The Cochrane Stroke Group Trials Register (last searched June 2003). The Cochrane Central Register of Controlled Trials (The Cochrane Library, Issue 3, 2002), MEDLINE (1966 to September 2002), EMBASE (1980 to September 2002), CINAHL (1982 to September 2002), PsychINFO (1967 to September 2002), Applied Science and Technology Plus (1986 to September 2002), Arts and Humanities Index (1991 to September 2002), Biological Abstracts (1969 to September 2002), General Science Plus (1994 to September 2002), Science Citation Index (1992 to September 2002), Social Sciences Citation Index (1991 to September 2002), and Sociofile (1974 to September 2002). Reference lists from relevant articles and textbooks were searched, and authors of known studies and pharmaceutical companies who manufacture psychotropic medications were contacted. SELECTION CRITERIA: Randomised and quasi-randomised controlled trials comparing different types of pharmaceutical agents with placebo, or various forms of psychotherapy with standard care (or attention control), in patients with recent, clinically diagnosed, acute stroke, where treatment was explicitly intended of treat depression. DATA COLLECTION AND ANALYSIS: Primary analyses focussed on the prevalence of diagnosable depressive disorder at the end of treatment. Secondary outcomes included depression or mood scores on standard scales, disability or physical function, death, recurrent stroke, and adverse effects. We did not pool the data for summary scores. We performed meta-analysis for only some binary endpoints and data on adverse events. MAIN RESULTS: Nine trials, with 780 participants, were included in the review. Data were available for seven trials of pharmaceutical agents, and two trials of psychotherapy. There were no trials of ECT. The analyses were complicated by the lack of standardised diagnostic and outcome criteria, and differing analytic methods. There was no strong evidence of benefit of either pharmacotherapy or psychotherapy in terms of a complete remission of depression following stroke. There was evidence of a reduction (improvement) in scores on depression rating scales, and an increase in the proportion of participants with anxiety at the end of follow up. REVIEWERS' CONCLUSIONS: This review found no evidence to support the routine use of pharmacotherapeutic or psychotherapeutic treatment for depression after stroke. More research is required before recommendations can be made about the most appropriate management of depression following stroke.

Interventions for preventing depression after stroke.

BACKGROUND: Abnormal mood is an important consequence of stroke and may affect recovery and outcome. However, depression and anxiety are often not detected or inadequately treated. This may in part be due to doubts about whether anti-depressant treatments commenced early after the onset of stroke will prevent depression and improve outcome. OBJECTIVES: To determine if pharmaceutical or psychological interventions can prevent the onset of depression, including depressive illness and abnormal mood, and improve physical and psychological outcomes, in patients with stroke. SEARCH STRATEGY: We searched the Cochrane Stroke Group trials register (June 2003). In addition we searched the following electronic databases: Cochrane Central Register of Controlled Trials (The Cochrane Library, Issue 3, 2002), MEDLINE (1966 to September 2002), EMBASE (1980 to September 2002), CINAHL (1982 to September 2002), PsychINFO (1967 to September 2002), Applied Science and Technology Plus (1986 to September 2002), Arts and Humanities Index (1991 to September 2002), Biological Abstracts (1969 to September 2002), General Science Plus (1994 to September 2002), Science Citation Index (1992 to September 2002), Social Sciences Citation Index (1991 to September 2002), and Sociofile (1974 to September 2002). Reference lists from relevant articles and textbooks were searched, and authors of known studies and pharmaceutical companies who manufacture psychotropic medications were contacted. SELECTION CRITERIA: Randomised and quasi-randomised controlled trials comparing different types of pharmaceutical agents (eg selective serotonin reuptake inhibitors) with placebo, or various forms of psychotherapy against standard care (or attention control), in patients with a recent clinical diagnosis of stroke, where the treatment was undertaken with the explicit intention of preventing depression. DATA COLLECTION AND ANALYSIS: The primary analyses focussed on the proportion of patients who met the standard diagnostic criteria for depression applied in the trials at the end of follow-up. Secondary outcomes included depression or mood scores on standard scales, disability or physical function, death, recurrent stroke, and adverse effects. MAIN RESULTS: Twelve trials involving 1245 participants were included in the review. Data were available for nine trials (11 comparisons) involving different pharmaceutical agents, and three trials of psychotherapy. The time from stroke onset to entry ranged from a few hours to six months, but most patients were recruited within one month of acute stroke. The duration of treatments ranged from two weeks to one year. There was no clear effect of pharmacological therapy on the prevention of depression or on other measures. A significant improvement in mood was evident for psychotherapy, but this treatment effect was small and from a single trial. There was no effect on diagnosed depression. REVIEWERS' CONCLUSIONS: This review identified a small but significant effect of psychotherapy on improving mood, but no effect of either pharmacotherapy or psychotherapy on the prevention of depressive illness, disability, or other outcomes. More evidence is therefore required before any recommendations can be made about the routine use of such treatments to improve recovery after stroke.

Pharmaceutical interventions for emotionalism after stroke.

BACKGROUND: Antidepressants may be useful in the treatment of abnormal crying associated with stroke. OBJECTIVES: To determine whether pharmaceutical treatment reduces the frequency of emotional displays in people who suffer from emotionalism after stroke. SEARCH STRATEGY: We searched the Cochrane Stroke Group Trials Register (last searched June 2003). In addition we searched the following electronic databases: Cochrane Central Register of Controlled Trials (The Cochrane Library, Issue 3 2002), MEDLINE (1966 to September 2002), EMBASE (1980 to September 2002), CINAHL (1982 to September 2002), PsychINFO (1967 to September 2002), Applied Science and Technology Plus (1986 to September 2002), Arts and Humanities Index (1991 to September 2002), Biological Abstracts (1969 to September 2002), General Science Plus (1994 to September 2002), Science Citation Index (1992 to September 2002), Social Sciences Citation Index (1991 to September 2002), and Sociofile (1974 to September 2002). We searched reference lists from relevant articles and textbooks, and contacted authors of known studies and pharmaceutical companies who manufacture psychotropic medications. SELECTION CRITERIA: Randomised and quasi-randomised controlled trials, comparing psychotropic medication to placebo, in people with stroke and emotionalism (also known as emotional lability or pathological crying and laughing). DATA COLLECTION AND ANALYSIS: Data were obtained on people who no longer met criteria for emotionalism, as defined in studies, and on reduction in frequency of crying at the end of treatment. Data were not pooled because of the multiplicity of definitions and outcome measures. MAIN RESULTS: Five trials involving 103 participants were included. Four trials showed large effects of treatment: 50% reduction in emotionalism, improvements (reduction) in the frequency of compulsive laughter, and lower (better) scores on the Pathological Laughter and Crying scale. The confidence intervals were wide, however, indicating that treatment may have had only a small positive effect, or even a small negative effect (in one trial). Subgroup analysis was not performed due to the multiple methods of assessment of emotionalism within and between trials. Only one study systematically recorded and reported adverse events; no discernible difference was seen between groups. Participants allocated active treatment were more likely to leave early from trials. REVIEWERS' CONCLUSIONS: Antidepressants can reduce the frequency and severity of crying or laughing episodes. The effect do not seem specific to one drug or class of drugs. However, our conclusions must be qualified by several methodological deficiencies in the studies. More reliable data are required before recommendations can be made about the treatment of post-stroke emotionalism.

Health outcomes 1 year after subarachnoid hemorrhage: An international population-based study. The Australian Cooperative Research on Subarachnoid Hemorrhage Study Group.

BACKGROUND: There is limited information about the long-term consequences of subarachnoid hemorrhage (SAH). METHODS: Data were obtained from a population-based study of aneurysmal SAH conducted in Australia and New Zealand between 1995 and 1998. The authors report health outcomes for survivors 1 year after the onset of SAH. RESULTS: From a total of 432 first-ever cases of SAH (76% due to confirmed cerebral aneurysm rupture) registered in four cities in Australia and New Zealand, 242 (56%) were alive approximately 1 year later (mean time 1.2 years), with 230 (95%) available for interview. Of those interviewed, 105 (46%) reported an incomplete recovery, with ongoing problems with memory (50%), mood (39%), speech (14%), and self-care (10%). Compared with age- and sex-adjusted Australian population norms, health-related quality of life, as determined by Short Form-36, was significantly lower for cases in the domains of role limitations that result from physical problems. However, there were no patient or disease characteristics that predicted complete recovery from SAH. CONCLUSIONS: A high proportion of long-term survivors of SAH experience ongoing deficits in high level (neuropsychological) functioning. These deficits result in impairment in social roles.

Health-related quality of life among long-term survivors of stroke : results from the Auckland Stroke Study, 1991-1992.

BACKGROUND AND PURPOSE: The consequences of stroke are a major health concern. This study was conducted to compare the health-related quality of life among long-term survivors of stroke with that of the general population. METHODS: Our data are taken from a population-based case-control study of all 6-year survivors of stroke with an age- and sex-matched control population. SF-36 mean scores for cases were compared with raw and standardized control and New Zealand norm mean scores. RESULTS: Of the original 1761 registered cases, 639 were still alive at 6-year follow-up, and all of these participated in the study. Case patients were more likely than control subjects to be dependent in all basic activities of daily living. Crude mean scores were lower for women; as age increased; for those living in institutions; when the SF-36 was completed by proxy; and when help was required with the activities of daily living. Cases had statistically lower mean scores than both the control group and New Zealand norms for physical functioning and general health. After standardization for age and sex, no differences were found between cases and controls in mental health and bodily pain. CONCLUSIONS: Health-related quality of life appears to be relatively good for the majority of patients 6 years after stroke. Despite significant ongoing physical disability, survivors of stroke appear to adjust well psychologically to their illness.

Upper gastrointestinal endoscopy: are preparatory interventions effective?

BACKGROUND: This study was designed to examine the effects of preparatory cognitive and behavioral information on self-confidence, anxiety, and negative affect elicited by an impending upper gastrointestinal endoscopy. METHODS: Forty-eight male and female out-patients, between 18 and 65 years of age, scheduled for a first-time, non-emergency, endoscopic examination were randomly assigned to receive one of four experimental interventions: cognitive, behavioral, combination, or attention-control. Measures of self-reported anxiety and self-reported self-confidence were obtained. RESULTS: Cognitive and combination intervention subjects were statistically younger than behavioral and attention-control subjects. A credibility assessment revealed that subjects who were taught visualization used it during their procedure. Results indicated that subjects in the cognitive and combination interventions experienced significant reduction in anxiety and increase in self-confidence from pre- to post-intervention. Self-confidence did not increase for subjects receiving the behavioral-only or the attention-control interventions. CONCLUSION: The results of this study show that preparatory information in general is effective in reducing anxiety and in increasing self-confidence before an upper gastrointestinal endoscopy. Results suggest that teaching subjects visualization before a procedure increases their use of visualization during a procedure.
