ItemEffectiveness of a Pragmatic Education Program Designed to Promote Walking Activity in Individuals With Impaired Glucose Tolerance A randomized controlled trial(AMER DIABETES ASSOC, 2009-08)OBJECTIVE To investigate whether a pragmatic structured education program with and without pedometer use is effective for promoting physical activity and improving glucose tolerance in those with impaired glucose tolerance (IGT). RESEARCH DESIGN AND METHODS Overweight and obese individuals with IGT were recruited from ongoing screening studies at the University Hospitals of Leicester, U.K. Participants were randomly assigned to one of three groups. Group 1 received a 3-h group-based structured education program designed to promote walking activity using personalized steps-per-day goals and pedometers. Group 2 received a 3-h group-based structured education program designed to promote walking activity using generic time-based goals. Group 3 received a brief information leaflet (control condition). Outcomes included an oral glucose tolerance test, standard anthropometric measures, ambulatory activity, and psychological variables. Follow-up was conducted at 3, 6, and 12 months. RESULTS A total of 87 individuals (66% male, mean age 65 years) were included in this study. At 12 months, significant decreases in 2-h postchallenge glucose and fasting glucose of -1.31 mmol/l (95% CI -2.20 to -0.43) and -0.32 mmol/l (-0.59 to -0.03), respectively, were seen in the pedometer group compared with the control group. No significant improvements in glucose control were seen in those given the standard education program. CONCLUSIONS This study suggests that a pragmatic structured education program that incorporates pedometer use is effective for improving glucose tolerance in those with IGT. This result is likely to have important implications for future primary care-based diabetes prevention initiatives.

ItemThe National Institute of Health Research (NIHR) Collaboration for Leadership in Applied Health Research and Care (CLAHRC) for Leicestershire, Northamptonshire and Rutland (LNR): a programme protocol(BMC, 2009-11-12)BACKGROUND: In October 2008, the National Institute for Health Research launched nine new research projects to develop and investigate methods of translating research evidence into practice. Given the title Collaborations for Leadership in Applied Health Research and Care (CLAHRC), all involve collaboration between one or more universities and the local health service, but they are adopting different approaches to achieve translation. METHODS: The translation and implementation programme of this CLAHRC has been built around a pragmatic framework for undertaking research to address live concerns in the delivery of care, in partnership with the managers, practitioners, and patients of the provider organisations of the CLAHRC. Focused on long-term conditions, the constituent research themes are prevention, early detection, self-management, rehabilitation, and implementation. Individual studies have various designs, and include both randomised trials of new ways to deliver care and qualitative studies of, for example, means of identifying barriers to research translation. A mix of methods will be used to evaluate the CLAHRC as a whole, including use of public health indicators, social research methods, and health economics. DISCUSSION: This paper describes one of the nine collaborations, that of Leicestershire, Northamptonshire, and Rutland. Drawing a distinction between translation as an organising principle for healthcare providers and implementation as a discrete activity, this collaboration is built on a substantial programme of applied research intended to create both research generation and research use capacity in provider organisations. The collaboration in Leicestershire, Northamptonshire, and Rutland has potential to provide evidence on how partnerships between practitioners, patients, and researchers can improve the transfer of evidence into practice.

ItemThe Prevalence of Depression in White-European and South-Asian People with Impaired Glucose Regulation and Screen-Detected Type 2 Diabetes Mellitus(PUBLIC LIBRARY SCIENCE, 2009-11-09)BACKGROUND: There is a clear relationship between depression and diabetes. However, the directionality of the relationship remains unclear and very little research has considered a multi-ethnic population. The aim of this study was to determine the prevalence of depression in a White-European (WE) and South-Asian (SA) population attending a community diabetes screening programme, and to explore the association of depression with screen-detected Type 2 diabetes mellitus (T2DM) and impaired glucose regulation (IGR). METHODOLOGY/PRINCIPAL FINDINGS: Participants were recruited from general practices in Leicestershire (United Kingdom) between August 2004 and December 2007. 4682 WE (40-75 years) and 1327 SA participants (25-75 years) underwent an Oral Glucose Tolerance Test, detailed history, anthropometric measurements and completed the World Health Organisation-Five (WHO-5) Wellbeing Index. Depression was defined by a WHO-5 wellbeing score < or =13. Unadjusted prevalence of depression for people in the total sample with T2DM and IGR was 21.3% (21.6% in WE, 20.6% in SA, p = 0.75) and 26.0% (25.3% in WE, 28.9% in SA, p = 0.65) respectively. For people with normal glucose tolerance, the prevalence was 25.1% (24.9% in WE, 26.4% in SA, p = 0.86). Age-adjusted prevalences were higher for females than males. Odds ratios adjusted for age, gender, and ethnicity, showed no significant increase in prevalent depression for people with T2DM (OR = 0.95, 95%CI 0.62 to 1.45) or IGR (OR = 1.17, 95%CI 0.96 to 1.42). CONCLUSIONS: Prior to the knowledge of diagnosis, depression was not significantly more prevalent in people with screen detected T2DM or IGR. Differences in prevalent depression between WE and SA people were also not identified. In this multi-ethnic population, female gender was significantly associated with depression.

ItemLearning a novel technique to identify possible melanomas: are Australian general practitioners better than their U.K. colleagues?(Springer Science and Business Media LLC, 2009-04-30)BACKGROUND: Spectrophotometric intracutaneous analysis (SIAscopy) is a multispectral imaging technique that is used to identify 'suspicious' (i.e. potentially malignant) pigmented skin lesions for further investigation. The MoleMate system is a hand-held scanner that captures SIAscopy images that are then classified by the clinician using a computerized diagnostic algorithm designed for the primary health care setting. The objectives of this study were to test the effectiveness of a computer program designed to train health care workers to identify the diagnostic features of SIAscopy images and compare the results of a group of Australian and a group of English general practitioners (GPs). METHODS: Thirty GPs recruited from the Perth (Western Australia) metropolitan area completed the training program at a workshop held in March 2008. The accuracy and speed of their pre- and post-test scores were then compared with those of a group of 18 GPs (including 10 GP registrars) who completed a similar program at two workshops held in Cambridge (U.K.) in March and April, 2007. RESULTS: The median test score of the Australian GPs improved from 79.5% to 86.5% (median increase 5.5%; p < 0.001) while the median test score of the English GPs improved from 74.5% to 86.5% (median increase 9.5%; p < 0.001). The Australian GPs had significantly higher pre-test scores but there were no significant differences in post-test scores between the Australian and English GPs or between the GPs and GP registrars. There was no significant difference in scores between GPs with previous dermoscopy experience or dermatology training. CONCLUSION: Most of the SIAscopy features can be learnt to a reasonable degree of accuracy with this brief computer training program. Although the Australian GPs scored higher in the pre-test, both groups had similar levels of accuracy and speed in interpreting the SIAscopy features after completing the program. Scores were not affected by previous dermoscopy experience or dermatology training, which suggests that the MoleMate system is relatively easy to learn.

ItemPractice nursing in Australia: A review of education and career pathways.(Springer Science and Business Media LLC, 2009-05-27)BACKGROUND: Nurses in Australia are often not educated in their pre registration years to meet the needs of primary care. Careers in primary care may not be as attractive to nursing graduates as high-tech settings such as intensive or acute care. Yet, it is in primary care that increasingly complex health problems are managed. The Australian government has invested in incentives for general practices to employ practice nurses. However, no policy framework has been developed for practice nursing to support career development and post-registration education and training programs are developed in an ad hoc manner and are not underpinned by core professional competencies. This paper reports on a systematic review undertaken to establish the available evidence on education models and career pathways with a view to enhancing recruitment and retention of practice nurses in primary care in Australia. METHODS: Search terms describing education models, career pathways and policy associated with primary care (practice) nursing were established. These search terms were used to search electronic databases. The search strategy identified 1394 citations of which 408 addressed one or more of the key search terms on policy, education and career pathways. Grey literature from the UK and New Zealand internet sites were sourced and examined. The UK and New Zealand Internet sites were selected because they have well established and advanced developments in education and career pathways for practice nurses.Two reviewers examined titles, abstracts and studies, based on inclusion and exclusion criteria. Disagreement between the reviewers was resolved by consensus or by a third reviewer. RESULTS: Significant advances have been made in New Zealand and the UK towards strengthening frameworks for primary care nursing education and career pathways. However, in Australia there is no policy at national level prepare nurses to work in primary care sector and no framework for education or career pathways for nurses working in that sector. CONCLUSION: There is a need for national training standards and a process of accreditation for practice nursing in Australia to support the development of a responsive and sustainable nursing workforce in primary care and to provide quality education and career pathways.

ItemTrials and tribulations of recruiting 2,000 older women onto a clinical trial investigating falls and fractures: Vital D study(BMC, 2009-11-25)BACKGROUND: Randomised, placebo-controlled trials are needed to provide evidence demonstrating safe, effective interventions that reduce falls and fractures in the elderly. The quality of a clinical trial is dependent on successful recruitment of the target participant group. This paper documents the successes and failures of recruiting over 2,000 women aged at least 70 years and at higher risk of falls or fractures onto a placebo-controlled trial of six years duration. The characteristics of study participants at baseline are also described for this study. METHODS: The Vital D Study recruited older women identified at high risk of fracture through the use of an eligibility algorithm, adapted from identified risk factors for hip fracture. Participants were randomised to orally receive either 500,000 IU vitamin D3 (cholecalciferol) or placebo every autumn for five consecutive years. A variety of recruitment strategies were employed to attract potential participants. RESULTS: Of the 2,317 participants randomised onto the study, 74% (n = 1716/2317) were consented onto the study in the last five months of recruiting. This was largely due to the success of a targeted mail-out. Prior to this only 541 women were consented in the 18 months of recruiting. A total of 70% of all participants were recruited as a result of targeted mail-out. The response rate from the letters increased from 2 to 7% following revision of the material by a public relations company. Participant demographic or risk factor profile did not differ between those recruited by targeted mail-outs compared with other methods. CONCLUSION: The most successful recruitment strategy was the targeted mail-out and the response rate was no higher in the local region where the study had extensive exposure through other recruiting strategies. The strategies that were labour-intensive and did not result in successful recruitment include the activities directed towards the GP medical centres. Comprehensive recruitment programs employ overlapping strategies simultaneously with ongoing assessment of recruitment rates. In our experience, and others direct mail-outs work best although rights to privacy must be respected. TRIAL REGISTRATION: ISRCTN83409867 and ACTR12605000658617.

ItemThe experience of providing young people attending general practice with an online risk assessment tool to assess their own sexual health risk(BIOMED CENTRAL LTD, 2009-03-12)BACKGROUND: Targeted chlamydia screening has been advocated to reduce chlamydia associated reproductive sequelae. General practitioners are well positioned to play a major role in chlamydia control. The primary aim of this pilot study was to measure the effect of offering an online sexual health assessment tool, Youth Check Your Risk, on chlamydia testing rates among young people attending general practices. The secondary aim was to test the acceptability of the tool among general practitioners and young people. METHODS: General practitioners at three practices in Melbourne, Australia, referred patients aged 16 to 24 years to Youth Check Your Risk http://www.checkyourrisk.org.au for use post-consultation between March to October 2007. The proportion of young people tested for chlamydia before and during the implementation of the tool was compared. Acceptability was assessed through a structured interviewer-administered questionnaire with general practitioners, and anonymous online data provided by Youth Check Your Risk users. RESULTS: The intervention did not result in any significant increases in the proportion of 16 to 24 year old males (2.7% to 3.0%) or females (6.3% to 6.4%) tested for chlamydia. A small increase in the proportion of 16 to 19 year old females tested was seen (4.1% to 7.2%). Of the 2997 patients seen during the intervention phase, 871 (29.1%) were referred to Youth Check Your Risk and 120 used it (13.8%). Major reasons for low referral rates reported by practitioners included lack of time, discomfort with raising the issue of testing, and difficulty in remembering to refer patients. CONCLUSION: Offering an online sexual risk assessment tool in general practice did not significantly increase the proportion of young people tested for chlamydia, with GPs identifying a number of barriers to referring young people to Youth Check Your Risk. Future interventions aimed at increasing chlamydia screening in general practice with the aid of an online risk assessment tool need to identify and overcome barriers to testing.

ItemMOSAIC (MOthers' Advocates In the Community): protocol and sample description of a cluster randomised trial of mentor mother support to reduce intimate partner violence among pregnant or recent mothers(BMC, 2009-05-27)BACKGROUND: Intimate partner violence (IPV) is prevalent globally, experienced by a significant minority of women in the early childbearing years and is harmful to the mental and physical health of women and children. There are very few studies with rigorous designs which have tested the effectiveness of IPV interventions to improve the health and wellbeing of abused women. Evidence for the separate benefit to victims of social support, advocacy and non-professional mentoring suggested that a combined model may reduce the levels of violence, the associated mental health damage and may increase a woman's health, safety and connection with her children. This paper describes the development, design and implementation of a trial of mentor mother support set in primary care, including baseline characteristics of participating women. METHODS/DESIGN: MOSAIC (MOtherS' Advocates In the Community) was a cluster randomised trial embedded in general practice and maternal and child health (MCH) nursing services in disadvantaged suburbs of Melbourne, Australia. Women who were pregnant or with infants, identified as abused or symptomatic of abuse, were referred by IPV-trained GPs and MCH nurses from 24 general practices and eight nurse teams from January 2006 to December 2007. Women in the intervention arm received up to 12 months support from trained and supported non-professional mentor mothers. Vietnamese health professionals also referred Vietnamese women to bilingual mentors in a sub-study. Baseline and follow-up surveys at 12 months measured IPV (CAS), depression (EPDS), general health (SF-36), social support (MOS-SF) and attachment to children (PSI-SF). Significant development and piloting occurred prior to trial commencement. Implementation interviews with MCH nurses, GPs and mentors assisted further refinement of the intervention. In-depth interviews with participants and mentors, and follow-up surveys of MCH nurses and GPs at trial conclusion will shed further light on MOSAIC's impact. DISCUSSION: Despite significant challenges, MOSAIC will make an important contribution to the need for evidence of effective partner violence interventions, the role of non-professional mentors in partner violence support services and the need for more evaluation of effective health professional training and support in caring for abused women and children among their populations. TRIAL REGISTRATION: ACTRN12607000010493.

ItemRasch analysis of the Multiple Sclerosis Impact Scale (MSIS-29)(BMC, 2009-06-22)BACKGROUND: Multiple Sclerosis (MS) is a degenerative neurological disease that causes impairments, including spasticity, pain, fatigue, and bladder dysfunction, which negatively impact on quality of life. The Multiple Sclerosis Impact Scale (MSIS-29) is a disease-specific health-related quality of life (HRQoL) instrument, developed using the patient's perspective on disease impact. It consists of two subscales assessing the physical (MSIS-29-PHYS) and psychological (MSIS-29-PSYCH) impact of MS. Although previous studies have found support for the psychometric properties of the MSIS-29 using traditional methods of scale evaluation, the scale has not been subjected to a detailed Rasch analysis. Therefore, the objective of this study was to use Rasch analysis to assess the internal validity of the scale, and its response format, item fit, targeting, internal consistency and dimensionality. METHODS: Ninety-two persons with definite MS residing in the community were recruited from a tertiary hospital database. Patients completed the MSIS-29 as part of a larger study. Rasch analysis was undertaken to assess the psychometric properties of the MSIS-29. RESULTS: Rasch analysis showed overall support for the psychometric properties of the two MSIS-29 subscales, however it was necessary to reduce the response format of the MSIS-29-PHYS to a 3-point response scale. Both subscales were unidimensional, had good internal consistency, and were free from item bias for sex and age. Dimensionality testing indicated it was not appropriate to combine the two subscales to form a total MSIS score. CONCLUSION: In this first study to use Rasch analysis to fully assess the psychometric properties of the MSIS-29 support was found for the two subscales but not for the use of the total scale. Further use of Rasch analysis on the MSIS-29 in larger and broader samples is recommended to confirm these findings.

ItemAgeing medical workforce in Australia - where will the medical educators come from?(BIOMED CENTRAL LTD, 2009-11-05)BACKGROUND: As the general practitioner and specialist medical workforce ages there is likely to be a large number of retirees in the near future. However, few Australian studies have specifically examined medical practitioner retirement and projected retirement patterns, and the subsequent impact this may have on training future health care professionals. METHODS: Extracts from the Australian Medicare database and Medical Labour Force Surveys are used to examine trends in attrition of general medical practitioners and specialists over the age of 45 years from the workforce and to predict their rate of retirement to 2025. RESULTS: The general medical practitioner workforce has aged significantly (p<0.05). Between the years 2000 and 2025, it was projected that 43% of the year 2000 general practitioner workforce and 56% of the specialist workforce would have retired. CONCLUSION: The ageing of the baby boomer and older cohorts of the general practitioner and specialist workforce will lead to a significant number of retirements over the next 20 years. Increasing the numbers of students and new medical schools has been heralded as a means of alleviating service shortages from about 2015 onwards; however, the retirement of a large proportion of experienced health care professionals may lead to shortages of educators for these students.
