Cohort profile: the 45 and up study.

In common with virtually all industrialized countries and many less developed nations, Australia is facing rapid population ageing. Historical patterns of fertility and migration, along with changes in life expectancy, mean that the over 65 age group is likely to increase by around 50% in the next 15–20 years. The further increase in the proportion of people in the very old age groups will result in the ‘ageing of the aged’. The challenges presented by the ageing of the population are far reaching. Discussions have tended to focus on its likely health and economic consequences; however, few aspects of society will remain unaffected by the issue. There is an urgent need for reliable evidence to inform policy to support healthy ageing. The concept of healthy ageing encompasses traditional ideas relating to freedom from disease, as well as broader considerations including independence, quality of life, management of disability, participation in society and the workforce and productivity. A wide range of factors are likely to affect health in later life, including socioeconomic, environmental and cultural variables, cigarette smoking, alcohol consumption, diet, physical activity, reproductive and hormonal factors, infections, availability of healthcare and use of pharmaceutical agents, as well as individuals’ susceptibility to disease. A comprehensive investigation of the determinants of healthy ageing must incorporate assessment of disease risk, quality of life and other indices, in relation to a very wide range of possible exposures, and with consideration of how these exposures might interact with one another. Research needs to be of a sufficient scale to provide specific information on the major diseases and health problems experienced in later life. This is because reliable assessments of risk factor–disease relationships require a substantial degree of pathological homogeneity of outcome and appropriate consideration of confounding. At the same time, research needs to be able to assess the broad risks and benefits of particular exposures, to allow meaningful conclusions to be reached about suitable public health interventions. Finally, it needs to be large and long term enough to track the impact of health interventions and policies at the population level. Australia has some unique characteristics that will impact on healthy ageing and provide particular challenges in delivering health care. For example, it has: a relatively heterogenous population with a large migrant community; an indigenous population with an average life expectancy 17 years less than for nonindigenous Australians; some remote and sparsely populated regions and a mixed health care system with responsibility shared between the national and state governments and delivery in both the public and private sectors. Excellent population-level databases relating to use of health services and medications, and registers of cancers and deaths, are available for statistical linkage with research data sets. There is therefore a need for research that addresses issues specific to the Australian population and makes use of the unique features of the Australian setting, giving the opportunity to provide insights of international relevance. The 45 and Up Study was conceived as a long-term collaborative resource to investigate healthy ageing, in response to the gaps in existing knowledge and the needs of researchers. Initial discussions among interested researchers resulted in the formation of a Scientific Steering Group in 2003 to oversee the development of the Study. The Study is auspiced by the Sax Institute, which also provided funding for its development. The Sax Institute is an independent organization with core funding from the state government of New South Wales, Australia’s most populous state. Its mission is to improve health through facilitating high-quality research and increasing the impact of this research on health policy and services; it has membership from y The Writing Committee is listed at the end of the report.

Measuring quality of life in cancer patients.

The diagnosis and management of cancer can have a major impact on every aspect of a patients quality of life. Despite its importance, quality of life is rarely a reported outcome in randomized clinical trials in cancer patients. Failure to collect quality-of-life information may reflect a lack of information among researchers and clinicians about the adequacy and relative merits of measures available for assessing quality of life. We reviewed the adequacy of the 17 existing scales for assessing quality of life in cancer patients against characteristics needed for an adequate measure. None of the existing measures met all of the criteria. Recommendations about the relative adequacy of existing scales were made.

Cancer patient satisfaction with care

A diagnosis of cancer places considerable stress on patients and requires them to make major adjustments in many areas of their lives. As a consequence, considerable demands are placed on health care providers to satisfy the complex care needs of cancer patients. Currently, there is little available information to indicate the extent to which cancer patients are satisfied with the quality of care they receive. The present study assessed the perceptions of 232 ambulatory cancer patients about the importance of and satisfaction with the following aspects of care: doctors technical competence and interpersonal and communication skills, accessibility and continuity of care, hospital and clinic care, nonmedical care, family care, and finances. The results indicate that all 60 questionnaire items used were considered to reflect important aspects of care, but that greater importance was given to the technical quality of medical care, the interpersonal and communication skills of doctors, and the accessibility of care. Most patients were satisfied with the opportunities provided to discuss their needs with doctors, the interpersonal support of doctors, and the technical competence of doctors. However, few patients were satisfied with the provision of information concerning their disease, treatment, and symptom control and the provision of care in the home and to family and friends.

Self‐reported long‐term outcomes of hysterectomy

Objectives— –To investigate womens perceptions of and satisfaction with the long‐term outcomes from a hysterectomy performed between 2 and 10 years ago and to determine whether satisfaction is related to demographic factors, factors associated with the hysterectomy, and the number or type of perceived benefits and problems associated with the hysterectomy.

The Study of environment on Aboriginal resilience and child health (SEARCH): study protocol

BackgroundAboriginal Australians have a life expectancy more than ten years less than that of non-Aboriginal Australians, reflecting their disproportionate burden of both communicable and non-communicable disease throughout the lifespan. Little is known about the health and health trajectories of Aboriginal children and, although the majority of Aboriginal people live in urban areas, data are particularly sparse in relation to children living in urban areas.Methods/DesignThe Study of Environment on Aboriginal Resilience and Child Health (SEARCH) is a cohort study of Aboriginal children aged 0-17 years, from urban and large regional centers in New South Wales, Australia. SEARCH focuses on Aboriginal community identified health priorities of: injury; otitis media; vaccine-preventable conditions; mental health problems; developmental delay; obesity; and risk factors for chronic disease. Parents/caregivers and their children are invited to participate in SEARCH at the time of presentation to one of the four participating Aboriginal Community Controlled Health Organisations at Mount Druitt, Campbelltown, Wagga Wagga and Newcastle. Questionnaire data are obtained from parents/caregivers and children, along with signed permission for follow-up through repeat data collection and data linkage. All children have their height, weight, waist circumference and blood pressure measured and complete audiometry, otoscopy/pneumatic otoscopy and tympanometry. Children aged 1-7 years have speech and language assessed and their parents/caregivers complete the Parental Evaluation of Developmental Status. The Study aims to recruit 1700 children by the end of 2010 and to secure resources for long term follow up. From November 2008 to March 2010, 1010 children had joined the study. From those 446 children with complete data entry, participating children ranged in age from 2 weeks to 17 years old, with 144 aged 0-3, 147 aged 4-7, 75 aged 8-10 and 79 aged 11-17. 55% were male and 45% female.DiscussionSEARCH is built on strong community partnerships, under Aboriginal leadership, and addresses community priorities relating to a number of under-researched areas. SEARCH will provide a unique long-term resource to investigate the causes and trajectories of health and illness in urban Aboriginal children and to identify potential targets for interventions to improve health.Background Aboriginal Australians have a life expectancy more than ten years less than that of non-Aboriginal Australians, reflecting their disproportionate burden of both communicable and non-communicable disease throughout the lifespan.

The Relative Effectiveness of Educational and Behavioral Instruction Programs for Patients With NIDDM: A Randomized Trial

In this randomized trial patients with non-insulin-dependent diabetes were allocated to one of four programs: a minimal instruction program (n=59). an education program of individual visits (n=57), an education program incorporating a group education course (n=66), and a behavioral program (n=59). Individual and group education programs had higher attrition rates than the behavioral and minimal programs. The four programs, which involved different amounts of patient contact time, delivery format, and instructional strategies. all produced reductions in HbA atid BMI, with no significant differences between the programs. There were no differences between groups over three time periods in total cholesterol, HDL cholesterol, systolic blood pressure, or proportion of patients consulting an ophthalmologist. The behavioral program ploduced a greater reduction in diastolic blood pressure over 12 months that the education programs and a greater reduction in the cholesterol risk ratio over 3 months than the other programs. The behavioral program patients were more likely to have visited a podiatrist after 6 months and reported higher satisfaction.

The effectiveness of two smoking cessation programmes for use in general practice: a randomised clinical trial.

OBJECTIVE--To evaluate a structured, behavioural change, smoking cessation intervention designed for use within general practice. DESIGN--Randomised controlled clinical trial. SETTING--General practices in Newcastle, Australia. PATIENTS--311 Patients identified as smokers by a screening question were enrolled in the study. Of these, 101 were assigned to a structured behavioural change programme, 104 to a simple advice programme adapted from previous research, and 106 to a control group. No significant differences were found between groups for demographic and smoking related variables before the study. INTERVENTIONS--Patients in the simple advice group received a brief statement of advice from the general practitioner as well as three pamphlets; those in the structured intervention group were given strategies which included attitude and behavioural change programmes as well as techniques to aid compliance. The amount of smoking in all groups was assessed by self reports with validation by measurement of salivary cotinine concentrations. MAIN OUTCOME MEASURE--Significant increase in cessation rates. CONCLUSIONS--Significant differences between controls and the structured behavioural change group were found at the one month follow up, but only for self reported abstinence. The simple advice programme did not produce any significant differences over the control group. General practitioner evaluation of the structured programme highlighted difficulties in relation to the duration of the intervention. Overall the structured programme in its present form did not appear to be an effective programme for use within general practice.

Determinants of career choices among women and men medical students and interns

Summary. Women continue to be poorly represented in medical specialties other than general practice. A cross‐sectional design was used to explore the development of career plans as medical training progressed; men and women students were compared in their first (n= 316), final (n= 295) and intern (n= 292) years. Women at each stage of training were significantly more likely to choose general practice as the field in which they were most likely to practise. There was little evidence that these differences were influenced by experience during training: women were as likely to choose general practice in first year as in the intern year. The most important determinant of career choice appeared to be the flexibility of training and of practice of medicine: variables such as the opportunity for part‐time training, flexible working hours and part‐time practice were important determinants of career choice and were of more importance to women than to men. The study also found high rates of discrimination or harassment reported by women medical students and interns. The results indicate the need for continued debate about these issues within medicine and the development of more flexible styles of medical training and practice.

Delay in consulting a medical practitioner about rectal bleeding.

STUDY OBJECTIVE--The aims were to estimate the incidence of rectal bleeding in the community, and to determine the proportion of individuals who delay or fail to seek medical advice after a first episode of rectal bleeding. DESIGN--The data were collected as part of a large scale general population survey of the health practices and attitudes of individuals in a randomly selected sample of 2121 households. SETTING--The survey was conducted in the Newcastle and Lake Macquarie areas of New South Wales, Australia, during 1987-88. PARTICIPANTS--Information about rectal bleeding was collected from 1213 individuals aged 40 years and over. MEASUREMENTS AND MAIN RESULTS--Of the 1213 people aged 40 years and over, 239 (20%) reported noticing rectal bleeding at some time in their life. However, since an estimated 4.5% had noticed rectal bleeding for the first time in the past year the true lifetime incidence of rectal bleeding is likely to be much higher. Of the 77 individuals who had noticed a first occurrence of rectal bleeding more than three months but less than five years prior to the interview, 23 (30%) had either not sought medical advice or had only done so after a period of delay. The most commonly reported reason for delay or failure to consult was thinking that the bleeding was not serious and would clear up by itself. CONCLUSIONS--The data suggest that prompt investigation of rectal bleeding is not occurring in a relatively large proportion of cases. However, in the absence of firm evidence that early detection improves prognosis, and considering the costs of screening, it would be premature to initiate programmes which encourage people to seek care promptly for this symptom.
