Biomedical health profiles of unpaid family carers in an urban population in South Australia.

OBJECTIVES: To compare the biomedical health profile and morbidity of adult carers with non-carers. METHODS: The North West Adelaide Health Study (NWAHS) is a representative population-based longitudinal biomedical cohort study of 4056 participants aged 18 years and over at Stage One. Informal (unpaid) carers were identified in Stage 3 of the project (2008-2010). Risk factors, chronic medical conditions and biomedical, health and demographic characteristics using self-report and blood measured variables were assessed. Data were collected through clinic visits, telephone interviews and self-completed questionnaires. Risk factors included blood pressure, cholesterol/lipids, body mass index (BMI), smoking and alcohol intake. Chronic medical conditions included cardiovascular and respiratory diseases, diabetes, and musculoskeletal conditions. Blood measured variables were routine haematology, biochemistry, Vitamin D, and the inflammatory biomarkers high sensitivity C-Reactive Protein (hs-CRP), Tumor Necrosis Factor alpha (TNFα) and Interleukin-6 (Il-6). RESULTS: The prevalence of carers aged 40 years and over was 10.7%, n = 191. Carers aged 40 years and over were more likely to assess their health status as fair/poor and report having diabetes, arthritis, anxiety and depression. They also reported insufficient exercise and were found to have higher BMI compared with non-carers. Significant findings from blood measured variables were lower serum Vitamin D and haemoglobin. Male carers had raised diastolic blood pressure, higher blood glucose, lower haemoglobin and albumin levels and slightly elevated levels of the inflammatory biomarkers TNFα and hs-CRP. DISCUSSION AND CONCLUSIONS: This study confirms informal carers had different biomedical profiles to non-carers that included some chronic physical illnesses. It identifies that both female and male carers showed a number of risk factors which need to be considered in future caregiver research, clinical guidelines and policy development regarding carer morbidity.

Ensuring healthy skin as part of wound prevention: an integrative review of health professionals' actions.

OBJECTIVE: To provide a synthesis of the best available, recent primary or secondary research evidence on early preventative activities taken to increase skin health, and reduce the incidence of facility-acquired skin tears and pressure ulcers (PUs) in community, residential and health-care institutions. METHOD: An integrative review focusing on a 10-year period, 2007-2017. A literature search of health databases was carried out, as well as a search of grey literature in relevant skin, wound care and nursing association journals. A second search was also conducted focused on literature from policy and guideline development organisations. Primary outcomes of interest were reduction in dry skin (xerosis), friable skin, or increases in healthy skin maintenance activities. Secondary outcomes of interest were reductions in PU or skin tear occurrences. Opinion, non-systematic literature reviews and discussion papers were excluded. RESULTS: Of the 4932 references obtained from the searches, a total of 33 articles were included in the review: 27 peer-reviewed journal articles and six articles from the grey literature search. No guideline was found that focused on maintaining skin health as a person ages. Studies identified the main factors for maintaining skin health as nutrition, hydration and skin care regimen. CONCLUSION: Skin care regimens, including a focus on good nutrition and pH balance, should start immediately on arrival in institutions such as hospitals or residential aged care, and continue throughout the stay.

Differences in risk factors and chronic conditions between informal (family) carers and non-carers using a population-based cross-sectional survey in South Australia.

BACKGROUND: There is growing discussion on the impact of informal caregiving on the health status and morbidity of family carers. Evidence suggests a proportion of carers may be at risk of poor health outcomes. However, there are limited population-based studies that provide representative data on specific risk factors among carers (eg, blood pressure, cholesterol, smoking status, activity and body mass index) and major chronic conditions (eg, asthma, diabetes and arthritis). This study aimed to redress that imbalance. METHOD: Self-reported data were from the South Australian Monitoring and Surveillance System (SAMSS), a representative cross-sectional state-wide population-based survey of 600 randomly selected persons per month. SAMSS uses computer-assisted telephone interviewing (CATI) to monitor chronic health-related problems and risk factors and to assess health outcomes. In total, 2247 family carers were identified from 35 195 participants aged 16 years and older for the 5-year period from 2010 to 2015. Logistic regression analyses examined associations of being a carer with self-reported chronic diseases and health risk factors. In addition, the population attributable risk (PAR) of being a carer was examined for selected chronic conditions. RESULTS: The prevalence of carers was 6.4%, and peak age group for carers was 50-59 years. Adjusted ORs for chronic conditions in carers were significant for all chronic conditions examined. Although there is a high prevalence of self-reported risk factors and chronic conditions among carers compared with non-carers at the population level, PAR findings suggest that caregiving is associated with a small to moderate increased risk of having these chronic conditions. CONCLUSIONS: Monitoring of carer health and morbidity particularly 'at risk' individuals such as female carers with asthma or diabetes remains important and provides an ongoing baseline for future surveys. To achieve this, caregiver-based studies need to become part of mainstream biomedical research at both epidemiological and clinical levels.

Frailty and usage of health care systems: Results from the South Australian Monitoring and Surveillance System (SAMSS).

OBJECTIVES: Little is known about frailty and its impact on health-care systems. Using large-scale population health surveillance data, this study determined the prevalence of frailty, its associated factors, and the impact it places on health care services. STUDY DESIGN: A cross-sectional snapshot of the 2013-2015 South Australian Monitoring and Surveillance System (SAMSS) database was used, focusing on individuals aged ≥65years. Frailty was assessed by the Frailty Index (FI), and classified as robust (scores≤0.1), pre-frail (>0.1 to ≤0.25), and frail (>0.25). RESULTS: 7207 people (53.7% female) were included; mean (SD) age was 74.8 (7.17) years. The mean (SD) FI score was 0.23 (0.11), with a 99% upper limit of 0.53. Over a third (36.3% (95% CI 34.8-37.9)) were classified as frail and over half (53.6% (95% CI 52.0-55.1)) as pre-frail. Frailty was less common in rural areas, and was associated with age, lower education level, and higher socioeconomic disadvantage. After adjustment for confounders, multivariable analyses showed a gradient effect by frailty classification with regard to both hospital- and non-hospital-based services. Frail older adults were more likely to present to hospital Emergency Departments (EDs) than their pre-frail or robust counterparts, yet visited the GP at the same rate as older adults with pre-frailty. CONCLUSION: Frail older adults were higher users of health care services, with the exception of GPs. Knowledge of the health service usage patterns of frail older adults can be used to direct public health policy and plan future GP provision.

SSRI antidepressant use potentiates weight gain in the context of unhealthy lifestyles: results from a 4-year Australian follow-up study.

OBJECTIVE: To examine the association between antidepressant use and weight gain, as well as the interaction with lifestyle factors. DESIGN: Longitudinal study. SETTING AND PARTICIPANTS: We used data from 2334 adults from two stages (4.4 years apart) of the North West Adelaide Health Study, including validated diet and lifestyle questionnaires, measured body weight and linked pharmaceutical prescription data. MAIN OUTCOME MEASURES: Body weight change. RESULTS: 188 (8.1%) participants had a mean annual number of 1-2 antidepressant prescriptions, and 212 (9.1%) had over two prescriptions. The mean annual weight gain was 0.12, 0.18 and 0.28 kg in non-users, low (1-2 prescriptions/year) and high (>2 prescriptions/year) antidepressant users, respectively. In multivariable regression models, antidepressant use was positively associated with weight gain: high antidepressant users gained an extra 0.22 (95% CI 0.00 to 0.44) kg per year. This association was mainly due to selective serotonin reuptake inhibitor (SSRI) use. High SSRI users gained 0.48 (95% CI 0.20 to 0.76) kg more than non-users. There was no association between tricyclic or other antidepressant use and weight gain. The association between SSRI use and weight gain was stronger among those with high intake of Western diet, greater sedentary activity, and who smoked. CONCLUSIONS: SSRIs use was associated with weight gain in the presence of unhealthy behaviours including Western diet, sedentarism and smoking.

The burden of cancer attributable to modifiable risk factors: the Australian cancer-PAF cohort consortium.

PURPOSE: To estimate the Australian cancer burden attributable to lifestyle-related risk factors and their combinations using a novel population attributable fraction (PAF) method that accounts for competing risk of death, risk factor interdependence and statistical uncertainty. PARTICIPANTS: 365 173 adults from seven Australian cohort studies. We linked pooled harmonised individual participant cohort data with population-based cancer and death registries to estimate exposure-cancer and exposure-death associations. Current Australian exposure prevalence was estimated from representative external sources. To illustrate the utility of the new PAF method, we calculated fractions of cancers causally related to body fatness or both tobacco and alcohol consumption avoidable in the next 10 years by risk factor modifications, comparing them with fractions produced by traditional PAF methods. FINDINGS TO DATE: Over 10 years of follow-up, we observed 27 483 incident cancers and 22 078 deaths. Of cancers related to body fatness (n=9258), 13% (95% CI 11% to 16%) could be avoided if those currently overweight or obese had body mass index of 18.5-24.9 kg/m2. Of cancers causally related to both tobacco and alcohol (n=4283), current or former smoking explains 13% (11% to 16%) and consuming more than two alcoholic drinks per day explains 6% (5% to 8%). The two factors combined explain 16% (13% to 19%): 26% (21% to 30%) in men and 8% (4% to 11%) in women. Corresponding estimates using the traditional PAF method were 20%, 31% and 10%. Our PAF estimates translate to 74 000 avoidable body fatness-related cancers and 40 000 avoidable tobacco- and alcohol-related cancers in Australia over the next 10 years (2017-2026). Traditional PAF methods not accounting for competing risk of death and interdependence of risk factors may overestimate PAFs and avoidable cancers. FUTURE PLANS: We will rank the most important causal factors and their combinations for a spectrum of cancers and inform cancer control activities.

Education and process change to improve skin health in a residential aged care facility.

We report on an intervention and evaluation in relation to changes in staff knowledge, time spent on healing and wound prevention and proportion of wounds in the facilities before and after. A rapid review of recent peer-reviewed literature (2006-2016) found 14 education-based intervention articles and provided the background and context for this intervention. A cohort of 164 nurses and personal care workers and 261 residents at two aged care-approved facilities contributed to this intervention on the effect of education, mentoring and practice change on staff knowledge and wound prevalence between 2015 and 2016. There was a significant decrease in pressure injury prevalence and an increase in the early identification of potential wounds between phase 1 and 3 across the two facilities. Overall, registered nurses and enrolled nurses showed significant increase in mean knowledge scores. There was a reorganisation of time spent on various wound care and prevention strategies that better represented education and knowledge. Wound management or prevention education alone is not enough; this study, using an educational intervention in conjunction with resident engagement, practice change, mentorship, onsite champions for healthy skin and product choice suggestions, supported by an organisation that focuses on a healthy ageing approach, showed improvement across two residential sites.

Influencing Cancer Screening Participation Rates-Providing a Combined Cancer Screening Program (a 'One Stop' Shop) Could Be a Potential Answer.

INTRODUCTION: Participation in established cancer screening programs remains variable. Therefore, a renewed focus on how to increase screening uptake, including addressing structural barriers such as time, travel, and cost is needed. One approach could be the provision of combined cancer screening, where multiple screening tests are provided at the same time and location (essentially a 'One Stop' screening shop). This cohort study explored both cancer screening behavior and the acceptability of a combined screening approach. METHODS: Participants of the North Western Adelaide Health Study (NWAHS), South Australia were invited to participate in a questionnaire about cancer screening behaviors and the acceptability of a proposed 'One Stop' cancer screening shop. Data were collected from 10th August 2015 to 18th January 2016, weighted for selection probability, age, and sex and analyzed using descriptive and multivariable logistic regression analysis. RESULTS: 1,562 people, 52% female (mean age 54.1 years ± 15.2) participated. Reported screening participation was low, the highest being for Pap Smear (34.4%). Common reasons for screening participation were preventing sickness (56.1%, CI 53.2-59.0%), maintaining health (51%, CI 48-53.9%), and free program provision (30.9%, CI 28.2-33.6%). Females were less likely to state that screening is not beneficial [OR 0.37 (CI 0.21-0.66), p < 0.001] and to cite sickness prevention [OR 2.10 (CI 1.46-3.00), p < 0.001] and free program [OR 1.75 (CI 1.22-2.51), p < 0.003] as reasons for screening participation. Of those who did not participate, 34.6% (CI 30.3-39.1%) stated that there was nothing that discouraged them from participation, with 55- to 64-year olds [OR 0.24 (CI 0.07-0.74), p < 0.04] being less likely to cite this reason. 21% (CI 17.2-24.8%) thought they did not need screening, while a smaller proportion stated not having time (6.9%, CI 4.9-9.7%) and the costs associated with screening (5.2%, CI 3.5-7.7%). The majority of participants (85.3%, CI 81.9-88.2%) supported multiple screening being offered at the same time and location. CONCLUSION: Identified screening behaviors in this study are similar to those reported in the literature. The high support for the concept of combined cancer screening demonstrates that this type of approach is acceptable to potential end users and warrants further investigation.

Is the Australian 75+ Health Assessment person-centred? A qualitative descriptive study of older people's perceptions.

Objective The aim of the present study was to explore the perspectives of older people following their recent participation in a 75+ Health Assessment (75+HA) and interrogate these perspectives using a person-centred lens. Methods A qualitative descriptive study design was used within a larger study funded by the Australian Primary Health Care Research Institute. Nineteen participants from four different general practices in one Australian state described their perceptions of the 75+HA in a face-to-face interview. Data were then analysed using a qualitative content analysis approach. Results The purpose of the 75+HA was not well understood by participants. Participant responses reveal that where, when, who and how a primary health professional conducted the 75+HA affected what older people talked about, the guidance they sought to deal with issues and, in turn, the actioning of issues that were discussed during the 75+HA. Conclusion To enable older people to make informed decisions about and successfully manage their own health and well being, and to choose when to invite others to act on their behalf, primary health professionals need to ask questions in the 75+HA within a person-centred mindset. The 75+HA is an opportunity to ensure older people know why they need support, which ones, and agree to, supports and services they require. What is known about the topic? The Australian Medicare Benefits Schedule includes the 75+HA, developed as a proactive primary care opportunity for general practitioners and practice nurses to identify issues affecting community-dwelling older people's health and well being. The aim of the 75+HA is to consider a broad range of factors that could affect physical, psychological and social functioning, which, in turn, affects overall health, and the capacity of older people to live independently in the community. Underlying the 75+HA is the importance of detecting early functional decline to enable healthy aging. What does this paper add? There is scant, if any, attention in the literature to the views of consumers who have completed a 75+HA, especially with regard to whether this opportunity is conducted with a person-centred mindset. This paper addresses this gap. Even after participating in the 75+HA, most participants were unclear as to the purpose of the assessment, what information had been recorded and what would happen from any concerns identified in the assessment. Comments about the 75+HA included that it did not ask people about their goals and what comprised their functionality to ensure their independent living. What are the implications for practitioners? A person-centred approach requires active collaboration between primary health professionals and older people who are living the process of, and planning for, aging-in-place. Assessments like the 75+HA can assist in identifying whether older people may be experiencing early signs of functional decline, even if older people self-report living without problems in their home. Practitioners need to ask questions of older people and respond to what they say with a person-centred mindset.

Unpaid Informal Caregivers in South Australia: Population Characteristics, Prevalence and Age-Period-Cohort Effects 1994-2014.

BACKGROUND: The ongoing need for an availability of informal carers is taking on greater relevance as the global burden of disease transitions from acute fatal diseases to long term morbidity. Growing evidence suggests that extra burden on family carers may further impact on their health and ability to provide care. Important as it is to monitor the prevalence of those conditions which influence the burden of disease, it is also important to monitor the prevalence and health profiles of those who provide the informal care. The aim of this study was to demonstrate the prevalence and demographics of adult carers aged 15 and over in the state of South Australia over 20 years between 1994 and 2014. METHODS: Data from nine representative, cross-sectional population surveys, conducted in South Australia, Australia were used, (total N = 26,788 and n = 1,504 carers). The adjusted prevalence estimate of carers and their demographic characteristics were determined. So as to examine whether there were any generational effects on the prevalence of carers, an Age-Period Cohort (APC) analysis was undertaken. RESULTS: The prevalence estimates of carers increased during the two decades from 3.7% in 1994 to 6.7% by 2014. Large increases in the proportion of retired carers, those aged 70 years and over, those carers employed, and those with higher educational qualifications were observed. There were also larger proportions of respondents with a country of birth other than Australia, UK, Ireland and European counties. The APC analysis illustrated an increasing prevalence rate over each decade for carers aged 20-80 years, especially for those over the age of 60 years. CONCLUSIONS: The results illustrate changing carer characteristics and carer prevalence estimates in South Australia as new generations of carers take on the caring role. There is a need to include questions regarding informal carers within ongoing mainstream population surveys, particularly at state levels, so as to plan for their future health care and home support.

The Australian 75+ Health Assessment: could it detect early functional decline better?

OBJECTIVE: The aim of the present study was to identify opportunities to improve the reach and impact of the Australian Medicare 75+ Health Assessment (75+HA) to detect early functional decline (FD). METHODS: A comparison of two published review articles produced two outputs: (1) assessments identified in the systematic review that underpinned the 75+HA items were ranked for evidence of effectiveness and compared with the volume of research into assessment areas identified by a recent review on indicators of early FD; and (2) items in the 75+HA were compared with those in the recent review. RESULTS: The review underpinning the 75+HA found 19 assessment areas, with strongest evidence of effectiveness for vision/hearing, teeth/oral, balance/gait, cognitive and service use. The more recent review reported on six domains (eight subdomains) of FD assessment: physical and cognitive elements of the performance capacity domain were the least well assessed, whereas the most comprehensively assessed domains were health service use, performance capacity (mental subdomain), participation (motivation/volition subdomain) and demographics. The 75+HA addresses only some items related to early FD as identified by the recent literature. CONCLUSION: Reassessment of the 75+HA with a view to including current evidence-based assessments for early FD is recommended. Updating the 75+HA items with ways to detect FD earlier may increase its relevance to Australia's ageing population.

Vitamin D levels in an Australian population.

BACKGROUND: Levels of vitamin D in the population have come under increasing scrutiny, however there are only a few studies in Australia which measure levels in the general population. The aim of this study was to measure the levels of vitamin D within a large population cohort and examine the association with seasons and selected demographic and health risk factors. METHODS: A longitudinal cohort study of 2413 participants in the northwest suburbs of Adelaide, South Australia conducted between 2008 and 2010 was used to examine serum levels of 25-hydroxy vitamin D (25(OH)D) in relation to demographic characteristics (age, sex, income, education and country of birth), seasons, the use of vitamin D supplements and selected health risk factors (physical activity, body mass index and smoking). Both unadjusted and adjusted mean levels of serum 25(OH)D were examined, as were the factors associated with the unadjusted and adjusted prevalence of serum 25(OH)D levels below 50 and 75 nmol/L. RESULTS: Overall, the mean level of serum 25(OH)D was 69.2 nmol/L with 22.7% of the population having a serum 25(OH)D level below 50 nmol/L, the level which is generally recognised as vitamin D deficiency. There were significantly higher levels of 25(OH)D among males compared to females (t = 4.65, p < 0.001). Higher levels of 25(OH)D were also measured in summer and autumn compared with winter and spring. Generally, mean levels of 25(OH)D were lower in those classified as obese. Smokers and those undertaking no or less than 150 minutes/week of physical activity also had lower levels of serum vitamin D. Obesity (as classified by body mass index), season and undertaking an insufficient level of physical activity to obtain a health benefit were significantly associated with the prevalence of vitamin D deficiency. CONCLUSIONS: Vitamin D deficiency is prevalent in South Australia, affecting almost one quarter of the population and levels are related to activity, obesity and season even when adjusted for confounding factors. Improved methods of addressing vitamin D levels in population are required.

Hip protectors: are they beneficial in protecting older people from fall-related injuries?

AIMS AND OBJECTIVES: To report findings of an investigation into the methodological quality of research informing the use of hip protectors for those clients in residential aged care considered to be at high risk of falls and to contribute to the translation of research evidence into practice by identifying issues surrounding the use of hip protectors in practice. BACKGROUND: Falls risk is a predominant concern when nursing older people, especially those in residential aged care. Fall-related injuries, specifically pertaining to the hip, yield a high cost to the individual both physically and psychologically. Accordingly, hip protectors are argued in related literature as a form of protection against such injuries. DESIGN: A database search as per a specified search strategy was conducted for quantitative research publications and randomised control trials. METHODS: English language publications were sought from the year 2000-2011. Searches were made, using specific combinations of keywords, in the following databases: MEDLINE via OvidSP, CINAHL via EBSCOHost, Ageline via OvidSP, Cochrane Library, The Joanna Briggs Institute and Google Scholar. RESULTS: Six articles were selected for review. Methodological quality of the research publications collated varied, and the use of hip protectors was deemed inconclusive. Compliance was raised as a prevailing issue. CONCLUSION: The problem of fall-related injuries is significant. Whilst some evidence is inconclusive, the use of hip protectors is recommended as best practice. RELEVANCE TO CLINICAL PRACTICE: The issue of compliance, however, was identified to affect the use of appliances in residential aged care. Addressing compliance issues must be tackled if hip protectors are to be part of a resident-centred approach.

Do trial-and-error practices and the use of the internet influence how medicines are used?

The aim of this research was to identify if people understood and used a practice termed 'trial and error' and the association of this practice to: (1) taking medicines as prescribed; and (2) use of the internet to assist their self-care decision-making. A national Computer Assisted Telephone Interview (CATI) was conducted in 2011 of a random sample of 3003 adults aged 18 years and over. Multivariable modelling, in stages, was undertaken adjusting for a range of demographics and associated health variables. There is a very strong relationship between the use of trial-and-error practices and not taking prescription medicines as prescribed. In addition, adults who state that they use trial-and-error practices to assist their health-related decision-making are more likely to have used the internet for information and then as a result, adjusted medicines or treatment. Any health care initiative directed at ensuring people take medicines as prescribed cannot dismiss the use of trial-and-error practices derived from information found on the internet.

Intergenerational learning about keeping health: a qualitative regional Australian study.

Understanding the conditions under which families try to influence members' health-related practices can provide information to build concepts adding to models of health promotion. This paper reports on an exploratory qualitative study examining the influences of intergenerational relationships in shaping beliefs, knowledge and practices about health and illness in a regional Australian city. We conducted semi-structured interviews with 27 adults with family members of other generations living in the city, all of whom had experience of asthma. We found that overall people's experience of health and illness, particularly in childhood, was taken for granted and not reflected upon. It was in the face of serious illness or death of a family member that objective knowledge about health and illness was sought and integrated within the family leading, in most cases, to significant lifestyle changes or 'doing things differently'. We drew on Bourdieu's concept of the three forms of theoretical knowledge in analysing our findings. We found the concept of knowledge as 'primary taken-for-granted experience', and the concept of praxeological knowledge as the knowledge created by the dialectical relationships between an individual subject and objectives structures were helpful. To influence individual health practices, we need to acknowledge how the family context confirms the taken-for-granted health practices of an individual and the family circumstances that might lead families to seek objective knowledge and make lifestyle changes to promote health.

TRialing individualized interventions to prevent functional decline in at-risk older adults (TRIIFL): study protocol for a randomized controlled trial nested in a longitudinal observational study.

BACKGROUND: Functional decline (FD) is a largely preventable feature of aging, characterized as gradual erosion of functional autonomy. This reduces an older person's capacity for safe, independent community living. The healthcare needs of an unprecedented aging population places pressure on health systems to develop innovative approaches to ensuring older people live healthy and independent lives for as long as possible. TRIIFL aims to demonstrate that: 1. Incipient FD in older people can be identified using a simple telephone-screening process within four weeks of discharge from an emergency department presentation for a minor health event; and 2. Early engagement into a person-centered individualized intervention arrests or reduces the rate of FD over the next 12 months. METHODS/DESIGN: A randomized controlled trial (RCT) nested within a 13-month longitudinal cohort study. The RCT (conducted over 12 months) tests the effectiveness of a novel, early, home-based, personalized program (compared with no intervention) in arresting or slowing FD. TRIIFL focuses on older adults living independently in the community, who have not yet had a serious health event, yet are potentially on the cusp of FD. Participants in the longitudinal cohort study will be recruited as they present to one large tertiary hospital Emergency Department, providing they are not subsequently admitted to a ward. Sample size calculations indicate that 570 participants need to be recruited into the longitudinal study, with 100 participants randomized into the trial arms. Measures from all subjects will be taken face-to-face at baseline (recruitment), then subsequently by telephone at one, four, seven and thirteen months later. Measures include functional abilities, quality of life, recent falls, mobility dependence, community supports and health service usage. Specific to the nested RCT, the quality of life tool (SF12) applied at one month, will identify individuals with low mental component quality of life scores, who will be invited to enter the RCT.Assessors will be blinded to RCT arm allocation, and subjects in the RCT will be blinded to the intervention being received by other subjects.

A survey to assist in targeting the adults who undertake risky behaviours, know their health behaviours are not optimal and who acknowledge being worried about their health.

BACKGROUND: Research indicates that those who are worried about their health are more likely to change their in-appropriate behavioural-related risk factors. A national survey was undertaken to determine adults who correctly perceive and actually undertake in-appropriate behavioural-related risk factors (smoking, physical activity, alcohol intake, fruit and vegetable consumption, weight and psychological distress) and are worried about their health. METHODS: Australian 2010 CATI survey of 3003 randomly selected adults. Perception and self-reported levels of each risk factor, and whether they worried that the level was affecting their health were assessed using univariate and multivariate analyses. RESULTS: The comparisons between perception of healthy behaviour and actual behaviour varied for each risk factor with 44.1% of people in the un-healthy weight range and 72.9% of those eating less than sufficient fruit and vegetables having the perception that their behaviour was healthy. The demographic and other related variables in the multivariate analyse for each risk factor varied considerably. For example the variables in the final multivariate model for smokers who were worried about their risk factor were markedly different to the other risk factor models and 45 to 54 year olds were more likely to be included in the final models for nearly all of the risk factor analyses. CONCLUSION: By limiting this analyses to those who are acknowledging (correctly or otherwise) that their perception of behaviour is making their health worse, this study has shown that the profile for each risk factor varies considerably. As such, evidence suggests specific targeted programs are required rather than a broad brush approach.

Learning from an epidemiological, population-based study on prescribed medicine use in adults.

OBJECTIVE: The aim of this study was to examine changes in the prevalence of use of prescribed medicines in Australian community samples. STUDY DESIGN AND SETTING: In this study, face-to-face interviews were carried out with random, representative samples of South Australian adults, aged ≥15 years. Data on self-reported use of prescribed medicines, most commonly reported categories of prescribed medicines and use of multiple medicines for common body systems were collected. It was not possible to distinguish between medicines prescribed for acute and chronic use. RESULTS: A total of 3015 respondents were interviewed in 2004 and 3034 in 2008, representing participation rates of 76% and 73%. There was no significant increase in the prevalence of use of ≥1 (46.8% vs 47.3%, p = 0.6) or ≥6 medicines (5.7% vs 5.5%, p = 0.7). In both years, the use of medicines was higher in women (56.7% vs 57.5%). On subgroup analyses, a significant reduction in the use of medicines was observed in respondents aged 15-24 (25.0% vs 18.5%, p = 0.01) and ≥65 years (87.7% vs 82.5%, p = 0.01), whereas use in those aged 35-44 years increased significantly (26.4% vs 33.6%, p = 0.01). The number of cardiovascular system agents (23.1% vs 24.6%, p = 0.20) and psychotropic medicines (9.8% vs 10.6%, p = 0.35) used by respondents remained unchanged while use of respiratory (7.2% vs 5.7%, p = 0.01) and musculoskeletal system medicines (8.7% vs 5.6% p= < 0.001) decreased significantly. CONCLUSIONS: In presenting what we believe is the first Australian population-based study to compare changes in prescribed medicines across the adult age spectrum, we highlight some key questions to ensure the quality use of medicines. Our findings identify a need to discuss de-prescribing, monitor practices to minimise adverse events and challenge if consumers and prescribers need to consider the costs to governments of medicines.

The doctor and the patient--how is a clinical encounter perceived?

OBJECTIVE: To examine the population distribution of different types of relationships between people with chronic conditions and their doctors that influence decisions being made from a shared-decision making perspective. METHODS: A survey questionnaire based on recurring themes about the doctor/patient relationship identified from qualitative in-depth interviews with people with chronic conditions and doctors was administered to a national population sample (n=999) of people with chronic conditions. RESULTS: Three factors explained the doctor/patient relationship. Factor 1 identified a positive partnership characteristic of involvement and shared decision-making; Factor 2 doctor-controlled relationship; Factor 3 relationship with negative dimensions. Cluster analysis identified four population groups. Cluster 1 doctor is in control (9.7% of the population); Cluster 2 ambivalent (27.6%); Cluster 3 positive long-term relationship (58.6%); Cluster 4 unhappy relationship (4.4%). The proportion of 18-34 year olds is significantly higher than expected in Cluster 4. The proportion of 65+ year olds is significantly higher than expected in Cluster 1, and significantly lower than expected in Cluster 4. CONCLUSION: This study adds to shared decision-making literature in that it shows in a representative sample of people with chronic illnesses how their perceptions of their experiences of the doctor-patient relationship are distributed across the population. PRACTICE IMPLICATIONS: Consideration needs to be given as to whether it is better to help doctors to alter their styles of interactions to suit the preferences of different patients or if it is feasible to match patients with doctors by style of decision-making and patient preference.
