Rural health research in Canada: at the crossroads

ABSTRACT: Rural health research in Canada is at the crossroads. Jolted by the establishment of the Canadian Institutes of Health Research, rural health researchers are trying hard to overcome past benign neglect and the lack of cohesion and collaboration within the rural health research community. Although there is considerable catching-up to do, rural health research in Canada has a firm foundation. Backed by a growing network of rural health research centres, researchers are searching for ways to work together in order to advance rural health research and the health and wellbeing of rural Canadians.     

The emergence of rural health research in Australia

ABSTRACT: The late 1980s saw a renewed interest in rural health in its own right with State jurisdictions establishing defined rural health units. There was recognition that health professionals in rural communities often needed training to fulfil their roles in rural and remote communities. Simultaneously, the number of regional universities increased. A number of such universities grouped to form a consortium and were funded through the Australian Health Ministers' Advisory Council (AHMAC) to form the Australian Rural Health Research Institute. Consequently, a series of conferences specifically addressing rural health research needs occurred, and the Australian Journal of Rural Health was established. Through both of these avenues a trend towards more research presentations and publications can be seen. The National Health and Medical Research Council, under the auspices of AHMAC, has provided an overview of the state of rural health research in Australia and developed recommendations, which form the framework for a future strategy for rural health research. These recommendations have been endorsed by AHMAC, which has now funded the initiation of the implementation of the strategy.     

How definition of mental health problems can influence help seeking in rural and remote communities

ABSTRACT: The present study sought to understand the rural and remote influences on people's identification of, and response to, mental health problems. Twenty-two key informants living in northern and western South Australia were interviewed. They included mental health and generalist health professionals, other human service workers and mental health consumers. Three themes are reported here: reluctance to acknowledge mental health problems and the avoidance of appropriate help; stigma and the avoidance of mental health services; and the influence of rural and remote circumstances. Most informants considered that many mental health problems were amenable to help from generalist workers, with backup support from mental health specialists. Informants thought this intervention to be appropriate because a common view of mental health problems as 'insanity' and a culture of self-reliance created a reluctance to seek help from a mental health specialist. These themes need to be taken into account when designing mental health interventions for rural and remote communities.     

Empowerment through information: supporting rural families of oncology patients in palliative care

A research project examining the support needs of families caring for a relative in palliative care was conducted in New South Wales in 1997. Data were collected from 19 families and 10 specialist palliative care nurses from eight centres throughout New South Wales using audio-taped interviews. The findings show that information was one of the most important support needs for families to enable them to effectively care for their sick relative. The information provided needed to meet the individual and varying needs of families at different stages of their palliative care journey. Often the families described not knowing what their information needs were until a crisis occurred. Lack of information on a range of areas, from practical resources to providing physical care and managing medications, was problematic. Health professionals need to take responsibility in determining if families are aware of the information available, identify the most appropriate medium for this material and provide it at the pace and time wanted by the individual family.     

Age and ageing: an overview

Europe is ageing, as exemplified by the UK population where, in the foreseeable future, more people will be over than under age 50: industry appears slow to recognise and appreciate all that older workers still have to offer: bundling them off into early retirement wastes precious talents. Memory difficulty is not an inevitable part of ageing.     

Childhood leukemia and rural population movements: Greece,Italy, and other countries

Mortality from childhood leukemia was examined particularly in rural countries in relation to any major ruralurban migration. Significant increases have been found in other situations of rural population mixing as predicted by the infection hypothesis. The 1950s and 1960s were of most interest since it preceded the decline in mortality brought about by effective chemotherapy in many countries. The 33 countries covered were all those in the World Health Organization's mortality database. No sensitive measure of rural-urban migration is available for international comparisons. However, it seems noteworthy that Greece and Italy, the two countries with the most striking levels of rural migration in the 1950s and 1960s, also had unusually high mortality rates from childhood leukemia. Greece was most affected proportionally by these population movements and from 1958 to 1972 had the highest recorded mortality from this cause in the world. The problems of international comparisons of mortality data dictate caution in drawing conclusions. However, against a background of other work on population mixing, and in the light of certain considerations, we suggest that the marked rural population mixing in Greece and Italy may have contributed to their high mortality rates from childhood leukemia in the 1950s and 1960s.Dr Kinlen holds a Gibb Fellowship from the Cancr Research Campaign.     

Determinants of leisure time physical activity in rural compared with urban older and ethnically diverse women in the United States

STUDY OBJECTIVE: Determinants of leisure time physical activity (LTPA) in rural middle aged and older women of diverse racial and ethnic groups are not well understood. This study examined: (1) urban-rural differences in LTPA by sociodemographic factors, (2) urban-rural differences in LTPA determinants, and (3) the pattern of relations between LTPA determinants and LTPA. DESIGN: A modified version of the sampling plan of the Behavioral Risk Factor Surveillance Survey (BRFSS) was used. Zip codes were selected with 20% or more of each of the following race/ethnic groups: African American, American Indian/Alaskan Native (AI/AN), and Hispanic. A comparison group of white women were also surveyed using standard BRFSS techniques. PARTICIPANTS: Rural (n=1242) and urban (n=1096) women aged 40 years and older from the US Women's Determinants Study. MAIN RESULTS: Rural women, especially Southern and less educated women, were more sedentary than urban women. Rural women reported more personal barriers to LTPA, cited caregiving duties as their top barrier (compared with lack of time for urban women), and had greater body mass indices. Rural women were less likely to report sidewalks, streetlights, high crime, access to facilities, and frequently seeing others exercise in their neighbourhood. Multivariate correlates of sedentary behaviour in rural women were AI/AN and African American race, older age, less education, lack of enjoyable scenery, not frequently seeing others exercise, greater barriers, and less social support (p<0.05); and in urban women, older age, greater barriers, less social support (p<0.05), and less education (p<0.09). CONCLUSIONS: Rural and urban women seem to face different barriers and enablers to LTPA, and have a different pattern of determinants, thus providing useful information for designing more targeted interventions.     

Population pharmacokinetics model and limited sampling strategy for intravenous vinorelbine derived from phase I clinical trials

AIMS: a) To characterize the pharmacokinetics of intravenous vinorelbine, b) to use a population analysis for the identification of patient covariates that might appreciably influence its disposition and c) to define a limited sampling strategy for further Bayesian estimation of individual pharmacokinetic parameters. METHODS: All data were collected from 64 patients (99 courses) entered in three different phase I trials that have been previously reported. All patients received vinorelbine as a 20 min infusion with dose levels ranging from 20-45 mg m-2. The population pharmacokinetic model was built in a sequential manner on a subset of two-thirds of the data, starting with a covariate-free model then progressing to a covariate model using the nonlinear-mixed effect methodology. The remaining one-third of the data were used to validate several sparse sampling designs. RESULTS: A linear three-compartment model characterized vinorelbine blood concentrations (n=1228). Two primary pharmacokinetic parameters (total clearance and volume of distribution) were related to various combinations of covariates. The relationship for total clearance (CLtotal (l h-1)=29.2xBSAx(1-0.0090 Plt)+6.7xWt/Crs) was dependent on the patient's body surface area (BSA), weight (Wt), serum creatinine (Crs) and platelet count before administration (Plt). The optimal limited sampling strategy consisted of a combination of three measured blood concentrations; the first immediately before the end of infusion or 20 min later, the second at either 1 h, 3 h or 6 h and the third at 24 h after drug administration. CONCLUSIONS: A population pharmacokinetic model and a limited sampling strategy for intravenous vinorelbine have been developed. This is the first population analysis performed on the basis of a large phase I database that has identified clinical covariates influencing the disposition of i.v. vinorelbine. The model can be used to obtain accurate Bayesian estimates of pharmacokinetic parameters in situations where extensive pharmacokinetic sampling is not feasable.     

RURAL URGENT CARE MODELS: WHAT ARE THEY MADE OF?

ABSTRACT: The study aimed to identify the elements that constitute rural urgent care systems. Participation in the study was sought from health professionals, welfare and emergency services sectors, and community members. Primary data were collected from informants through interviews and focus groups in five rural communities of different sizes. Twelve common elements to rural urgent care systems were identified and divided into two categories: (i) infrastructure; and (ii) personnel. Infrastructure included organisational support, community support, transport, communication and coordination processes, facilities and equipment, and community knowledge and information. Personnel included nurses, doctors, community leaders, health and welfare professionals, emergency service workers and ambulance officers. The study's major outcome was the recognition that rural urgent care systems consist of a balance of interrelated elements. These elements are context driven, with geographical, social and economic environments having a substantial impact on the ability of rural communities to develop and sustain their urgent care systems.     

AMALGAMATION OF HEALTH SERVICES IN SOUTH‐WEST VICTORIA: REINVENTION OR SURVIVAL?

ABSTRACT: In Australia 'the hospital' has long been considered the cornerstone of small, rural health services. However, this premise has been altered significantly by the introduction of casemix loading and diagnostic-related groups that promote a rationalised output-based model of management. In the light of these changes, many rural health services have struggled to reinvent themselves by establishing a range of service models such as Multi-purpose Service (MPS) and Health Streams, while maintaining traditional models (i.e. bush nursing centres, nursing homes and aged-care facilities). These changes are about survival. This paper analyses one such case in south-west Victoria, the Macarthur and District Community Outreach Service, and compares the outcomes with other similar Victorian rural health research projects. Particular attention is paid to the nature of the health services, the management of change and the proposed health outcomes for the local rural communities. In conclusion, it is argued that this study adds to the body of knowledge surrounding the construction of models of community health and development programming, These models impact upon future rural and remote area initiatives throughout Australia.
