Statin-use and perceptions of high cholesterol as predictors of healthy lifestyle behaviours in Nigerians.

It is unclear how statin-use influences the adoption of healthy lifestyle choices. It is important to understand the nature of this relationship as this could facilitate targeted public health interventions which could help promote a healthy lifestyle, curb the rise of non-communicable diseases, and facilitate overall health. This study aimed to explore whether statin-use influenced the adoption of healthy lifestyle choices by changing the way urban and semi-urban Nigerians thought about their high cholesterol and their future risk of cardiovascular disease. Structured questionnaires were used to compare the lifestyle behaviours, perceptions of high cholesterol and future risk of cardiovascular disease of statin users and non-statin users recruited in urban and a semi-urban Nigeria. In-depth, face-to-face interviews were used to further explore the relationship between statin-use and the adoption of healthy lifestyle choices, and explore the influence of personal and social factors on this relationship. The odds of adopting a low-fat diet increased as perceived statin-effectiveness increased (OR = 2.33, p<0.05), demonstrating a synergistic relationship between statin-use and the adoption of healthy of lifestyle choices. In addition to this synergistic association, at interview, two other relationships were found between statin use and the adoption of healthy lifestyle choices: an antagonistic relationship fuelled by a strong perception of statin effectiveness and a perceived inability to make healthy lifestyle changes, which favoured statin-use, and an antagonistic relationship fuelled by congruous cause-control beliefs and concerns about medication-use which favoured the adoption of healthy lifestyle choices. The odds of adopting a low-fat diet was 5 times greater in urban dwellers than in semi-urban dwellers (p<0.01). Statin-use influenced the adoption of healthy lifestyle choices in three different ways, which require exploration at clinical consultation. Gender, social obligations, and physical environment also influenced statin-use and the adoption of healthy lifestyle choices.

Measuring patient-perceived continuity of care for patients with long-term conditions in primary care.

BACKGROUND: Continuity of care is widely acknowledged as important for patients with multi-morbidity but simple, service-orientated indices cannot capture the full impact of continuity in complex care delivery systems. The patient's perspective is important to assess outcomes fully and this is challenging because generic measures of patient-perceived continuity are lacking. We investigate the Chao Perception of Continuity (Chao PC) scale to determine its suitability as a measure of continuity of care for patients with a long-term condition (stroke), and co-morbidity, in a primary care setting. DESIGN AND SETTING: A questionnaire study embedded in a prospective observational cohort study of outcomes for patients following acute stroke. PARTICIPANTS: 168 community dwelling patients (58% male) mean age 68 years a minimum one year post-stroke. Functional status: Barthel Index mean =16. INTERVENTION: A 23-item questionnaire, the Chao Perception of Continuity (Chao PC) scale, sent by post to their place of residence or administered face to face as part of the final cohort study assessment. RESULTS: 310 patients were invited to participate; 168 (54%) completed a questionnaire. All 23 questionnaire items were entered into a Principal Component Analysis. Emergent factors from the exploratory analysis were (1) inter-personal trust (relational continuity); (2) interpersonal knowledge and information (informational and relational continuity) and (3) the process of care (managerial continuity). The strongest of these was inter-personal trust. CONCLUSION: The context-specific items in the Chao PC scale are difficult for respondents to interpret in a United Kingdom Primary Care setting resulting in missing data and low response rates. The Chao-PC therefore cannot be recommended for wider application as a general measure of continuity of care without significant modification. Our findings reflect the acknowledged dimensions of continuity and support the concept of continuity of care as a multi-dimensional construct. We demonstrate the overlapping boundaries across the dimensions in the factor structure derived. Trust and interpersonal knowledge are clearly identified as valuable components of any patient-perceived measure of continuity of care.

Mixture modelling analysis of one-month disability after stroke: stroke outcomes study (SOS1).

PURPOSE: Understanding the heterogeneity in disability after stroke is important to guide treatment and rehabilitation planning. We explored mixture modelling analysis to identify subgroups of stroke disability and factors associated with disability subgroups. METHOD: Analyses were performed using secondary data from a cohort of 448 stroke patients who participated in a 2-year study of stroke outcomes. Mixture modelling approach was used to determine subgroups of early disability following stroke based on the Barthel Index, General Health Questionnaire (GHQ-28), Frenchay Activities Index and the Nottingham Extended Activities of Daily Living Scale. RESULTS: Five distinct disability groups were identified. Nineteen (4.2%) patients were classified as having very severe disability, 58 (12.9%) severe disability, 133 (29.7%) moderate disability, 198 (44.2%) mild disability and 40 (8.9%) a mood disorder. Compared to the mild group, patients in the "very severe" group were more likely to be elderly and to have had a previous stroke, and less likely to live alone and had a greater risk of mortality 2 years after stroke. Patients in the mood disorder group showed greater dependency in activities of daily living were younger compared to the other groups and had a greater risk of having mood symptoms 2 years after stroke. CONCLUSION: Mixture modelling of 1-month disability after stroke using a broad range of outcome measures has identified clinically meaningful groups relating to long-term outcomes.

Lifestyle referral assessment in an acute cardiology setting: study protocol for a randomized controlled feasibility trial.

BACKGROUND: Lifestyle and behaviour change are important factors in the prevention of cardiovascular disease and reduction of premature mortality. Public health initiatives have focused on opportunities for healthcare staff to deliver lifestyle advice routinely in primary and secondary care but there is no consistent approach to onward referrals and the rate of uptake of advice remains low. We do not know if advice is more effective in supporting behaviour change when a systematic approach is taken that includes identification of barriers to change, directing patients toward services, referral to services, and feedback on outcome. METHODS AND DESIGN: This is a single-centre, randomized, unblinded feasibility trial in an acute hospital setting which aims to assess the feasibility of a definitive trial and provide proof of concept for the systematic delivery of individualized lifestyle advice in patients managed through an acute cardiology in-patient service.Patients will be recruited before discharge and randomized to two groups. A control group will receive the usual lifestyle assessment and referral, while an intervention group will receive the usual assessment plus the new individualized lifestyle assessment and referral. The new assessment will inform assignment of each patient to one of three categories based on personal barriers to change. Patients may be referred to a formal lifestyle-change programme, through the 'Leeds Let's Change' website, or they may be guided in self-management, using goal setting, or they may be assigned to a 'deferment' category, for reassessment at follow-up. These latter patients will be given a contact card for the 'Leeds Let's Change' service. DISCUSSION: Lifestyle change is an important mechanism for improving health and wellbeing across the population but there are widely acknowledged difficulties in addressing lifestyle factors with patients and supporting behaviour change. A systematic approach to assessment would facilitate audit and provide an indicator of the quality of care. The new assessment template has been designed to be quick and easy to use in practice and could, for example, be added to a primary care consultation or form part of a nursing discharge assessment in an acute setting. TRIAL REGISTRATION: Current Controlled Trials ISRCTN41781196.

Oncology professionals' views on the use of antidepressants in cancer patients: a qualitative interview study.

OBJECTIVES: Emotional distress, including depression, is an important issue for cancer patients and their families. Guidelines recommend the use of antidepressant drugs (ADs) for the management of depression in cancer. This study explores the views of oncology professionals about the inclusion of ADs in treatment plans. DESIGN: Semi-structured interview study. Data were analysed using framework analysis. SETTING: A specialist cancer centre and six district general hospitals across the Yorkshire Cancer Network. PARTICIPANTS: 18 randomly selected professionals from lung, breast, urology and colorectal cancer teams: oncologists (n=8), surgeons (n=3), clinical nurse specialists (n=2) and ward nurses (n=5). RESULTS: Three main themes emerged relating to professionals' attitudes, knowledge and behaviour. Positive attitudes were primarily expressed by nurses. However, negative views were expressed about the potential for over-reliance on ADs, and their use constituting 'giving in'. Doctors reported a lack of confidence in the use of and knowledge about ADs with an associated reluctance to prescribe. The general practitioner (GP) was regarded as the most appropriate professional to prescribe ADs. CONCLUSIONS: Cancer professionals highlighted a need for training in the appropriate use of ADs. Further, this research suggests that negative attitudes towards antidepressants may be a factor in their exclusion from treatment plans. The GP is seen to have a key prescribing role for AD therapy; however, it is unclear whether the GPs is asked to do this. This research raises questions about the adequacy of ADs in cancer care and to what extent the GP is able to meet this need.

Stroke survivors who score below threshold on standard depression measures may still have negative cognitions of concern.

BACKGROUND AND PURPOSE: There has been an increase in screening for depression in the physically ill. We explored whether important negative cognitions may be missed by conventional approaches to screening for depression in 2 independently conducted stroke studies with similar methods. METHODS: The Auckland Regional Community Stroke (ARCOS) study was a prospective, population-based stroke incidence study conducted in Auckland, New Zealand, for 12 months in 2002 to 2003. The Stroke Outcomes Study was a prospective, hospital cohort study conducted in Leeds and Bradford, United Kingdom, for 33 months in 2002 to 2005. Symptoms of abnormal mood were assessed at 6 months in ARCOS with a single simple question, "Do you often feel sad and depressed?" and the 28-item General Health Questionnaire administered as part of a structured interview and in the Stroke Outcomes Study with the 28-item General Health Questionnaire and a single question about depressed mood taken from the Present State Examination. RESULTS: Mood data were available at 6 months from 770 ARCOS and 492 Stroke Outcomes Study participants. A significant proportion (up to 28%) of people who did not meet study criteria for depression reported important negative cognitions such as hopelessness, worthlessness, or suicidality. People who were older, dependent in activities of daily living, or not partnered were more likely to report negative cognitions. CONCLUSIONS: Important negative cognitions, including suicidal thoughts, may be missed when people are screened for depression after stroke. Screening alone is not an adequate substitute for a sensitive exploration of the psychological impact of stroke on the survivor.

The Stroke Outcomes Study 2 (SOS2): a prospective, analytic cohort study of depressive symptoms after stroke.

BACKGROUND: Mood disorder is recognised as an important and common problem after stroke but little is known about the longer term effects of mood on functional outcomes. This protocol paper describes the Stroke Outcomes Study 2 (SOS2), a research study conducted in two large acute NHS Trusts in the North of England, which was designed to investigate the impact of early depressive symptoms on outcomes after an acute stroke. METHODS AND DESIGN: SOS2 was a prospective cohort study that aimed to recruit patients in the first few weeks after a stroke, and to follow them up at regular intervals for one year thereafter in order to describe the trajectory of psychological symptoms and study their impact on physical functional recovery. Measures of mood and function were completed at baseline (approximately 3 weeks) and at four follow-up time-points: approximately 9, 13, 26 and 52 weeks after the index stroke. DISCUSSION: Recruiting patients to research studies soon after an acute stroke is difficult. Mortality following stroke is approximately 30% and in the region of half the patients that survive the initial event are significantly disabled. Together these factors reduced the number of patients available to participate in SOS2 but once recruited to the study the drop-out rate was relatively low. During the recruitment period over 6000 admissions for stroke or query stroke were screened for eligibility. A cohort of 592 study participants was finally achieved.
