Carpal Tunnel Syndrome In Primary Care: A Report From Aspn. Ambulatory Sentinel Practice Network, R Miller, Donald Iverson, R Fried, L Green, Paul Nutting

Don C. Iverson

Carpaltunnelsyndrome is the entrapment neuropathy of the medign nerve at the wrist. It is the most common nerve compression disorder seen by physicians, affecting women up to five times more frequently than men, especially during the reproductive years. Carpaltunnelsyndrome is known to be aggravated during pregnancy and menopause. Primary care physicians can expect to see approximately 1.01 cases of carpaltunnelsyndrome per 1,000 office encounters, with a female age-adjusted rate of 1.49 per 1,000 person-years. Physicians can identify this syndrome with an accurate and detailed history and physical exam. In most cases, electrodiagnostic studies, such as nerve conduction velocities and/or electromyography, …

Physician Assessment Of Patient Motivation: Influence On Disposition For Follow-Up Care, R Mcartor, Donald Iverson, D Benken, Valerie Gilchrist, L Dennis, R Broome

Don C. Iverson

This study of 3,318 outpatient visits evaluated the influence of the physician-assessed level of patient motivation on the level of physician involvement in follow-up care. Data collected included patient demographics, health risk factors, physician-assessed level of patient motivation, and the disposition for follow-up care (return office visit or self-care). Physicians more frequently scheduled patients for a return office visit, regardless of assessed level of patient motivation, when they presented with a traditional biomedical problem. Patients with health promotion-disease prevention problems were more frequently relegated to self-care; patients physicians judged to be poorly motivated were four times as likely to be …

Integrating School Of Community Efforts To Promote Health: Strategies, Policies, And Methods, Lloyd Kolbe, Donald Iverson

Don C. Iverson

The purposeful integration of school and community efforts indeed may be the critical element in a formula to promote the health of school-aged children and youth. Obviously there are numerous strategies, policies, and methods to functionally integrate school and community activities. As concluded by the Director of the U.S. Office of Maternal and Child Health in a paper on "New Policies in School Health": What is required, then, are not new policies in school health, but, a reaffirmation and implementation of policies that have been with us for many years.

Perceived Environment Attributes, Residential Location And Walking For Particular Purposes, Nancy Humpel, Donald Iverson, Neville Owen, Eva Leslie, Adrian Bauman

Don C. Iverson

BACKGROUND: Identifying environmental factors that can influence physical activity is a public health priority. We examined associations of perceived environmental attributes with walking for four different purposes: general neighborhood walking, walking for exercise, walking for pleasure, and walking to get to and from places. METHODS: Participants (n =399; 57% women) were surveyed by mail. They reported place of residence, walking behaviors, and perceptions of neighborhood environmental attributes. RESULTS: Men with the most positive perceptions of neighborhood "aesthetics" were significantly more likely (odds ratio [OR]=7.4) to be in the highest category of neighborhood walking. Men who perceived the weather as not …

The Older Patient, The Doctor And The Trainee: Patients' Attitudes And Implications For Models Of Care, Andrew Bonney, Sandra Jones, Donald Iverson

Don C. Iverson

Aims & rationale/Objectives Population ageing poses major challenges for health systems. Additionally, training future general practitioners in the management of older and chronically ill patients is potentially hampered by the reluctance of these patients to consult trainees for chronic care. This paper reports a cross-sectional study investigating the attitudes of older patients to trainees, to inform strategies to improve older patient-trainee interaction. Methods The survey instrument was distributed to 1900 patients aged 60 and over from 38 training practices from five Australian states using a stratified, randomised cluster sampling process. Generalised estimating equation models were used for analysis. Principal findings …


Examining The Pathways Linking Chronic Sleep Restriction To Obesity, Christopher A. Magee, Xu-Feng Huang, Donald C. Iverson, Peter Caputi Jun 2012

Examining The Pathways Linking Chronic Sleep Restriction To Obesity, Christopher A. Magee, Xu-Feng Huang, Donald C. Iverson, Peter Caputi

Don C. Iverson

A growing number of studies have identified chronic sleep restriction as a potential risk factor for obesity. This could have important implications for how obesity is prevented and managed, but current understanding of the processes linking chronic sleep restriction to obesity is incomplete. In this paper, we examined some of the pathways that could underlie the relationship between chronic sleep restriction and obesity. This involved exploring some of the potential environmental, health, behavioral, and sociodemographic determinants of chronic sleep restriction, which require further investigation in this context. Three pathways that could potentially link chronic sleep restriction to obesity were then …


Patients' Attitudes To General Practice Registrars: A Review Of The Literature, Andrew Bonney, Lyn Phillipson, Samantha Reis, Sandra Jones, Donald Iverson Jun 2012

Patients' Attitudes To General Practice Registrars: A Review Of The Literature, Andrew Bonney, Lyn Phillipson, Samantha Reis, Sandra Jones, Donald Iverson

Don C. Iverson

Introduction With the population ageing, it is imperative for training practices to provide GP registrars with sound experience in managing the health problems of older persons, especially chronic conditions. However, it is reported that a significant proportion of these patients will be resistant to consulting registrars, with concerns regarding disruption of continuity of care being a significant factor. The challenge for training practices is to identify approaches to engage registrars in the management of older patients whilst maintaining patient satisfaction. This paper presents a review of the literature on patient attitudes to general practice registrars to better understand the nature …


Older Patients' Attitudes To General Practice Registrars: A Qualitative Study, Andrew Bonney, Lyn Phillipson, Sandra Jones, Donald Iverson Jun 2012

Older Patients' Attitudes To General Practice Registrars: A Qualitative Study, Andrew Bonney, Lyn Phillipson, Sandra Jones, Donald Iverson

Don C. Iverson

Background Research suggests that older patients may be reluctant to engage general practice registrars (GPRs) in their care. The authors undertook a qualitative study of the attitudes of older patients to GPRs to investigate this issue. Method Thirty-eight patients aged 60 years and over from three training practices participated in semistructured telephone interviews, which explored patients responses to GPRs. The interviews were recorded, transcribed and analysed using a template analysis approach. Results Analysis of the interviews produced five major themes concerning patient attitudes to GPRs: desire for continuity, desire for access, openness, trust and a desire for meaningful communication. Discussion …


'Just Don't Eat Chicken': The Challenge Of Engaging Australian Adults In Appropriate Preventive Behaviours For Bird Flu, Sandra Jones, Donald Iverson, Louise Waters Jun 2012

'Just Don't Eat Chicken': The Challenge Of Engaging Australian Adults In Appropriate Preventive Behaviours For Bird Flu, Sandra Jones, Donald Iverson, Louise Waters

Don C. Iverson

Leading medical experts have cautioned about the risk of inappropriate behavioural responses as a result of fear of avian influenza (bird flu) even before a pandemic emerges, and have emphasised the need for appropriate risk communication strategies. There is a paucity of in-depth qualitative research into the general public's understanding of, and reactions to, such potential health crises. Four focus groups were conducted in April 2006 and a further eight focus groups in July 2006, to examine people's knowledge, beliefs and behaviours in relation to avian influenza, with the primary aim being to inform the development of future communication strategies. …


Australian Adolescents' Compliance With Sun Protection Behaviours During Summer: The Importance Of The School Context, Melinda Williams, Sandra C. Jones, Peter Caputi, Donald Iverson Jun 2012

Australian Adolescents' Compliance With Sun Protection Behaviours During Summer: The Importance Of The School Context, Melinda Williams, Sandra C. Jones, Peter Caputi, Donald Iverson

Don C. Iverson

Adolescents exhibit significantly lower sun protection behaviours than adults in Australia. While many studies have assessed the sun protection behaviours of adolescents during summer, few studies have explored the differences in sun protection behaviours of adolescents across key contexts relevant to adolescents during summer—notably school time, weekends and school holidays. Greater understanding of differences in behaviours across these contexts provides more detailed explanations of the nature of adolescent ultraviolet exposure and thereby facilitates improved targeting of interventions for this segment whose behaviour is considered hard to change. In this study, we explore the differences in self-reported, habitual, sun protection behaviours …


Australian Women's Perceptions Of Breast Cancer Risk Factors And The Risk Of Developing Breast Cancer, Sandra C. Jones, Christopher A. Magee, Lance R. Barrie, Donald C. Iverson, Parri Gregory, Emma L. Hanks, Anne E. Nelson, Caroline L. Nehill, Helen M. Zorbas Jun 2012

Don C. Iverson

Background Numerous studies have shown that the majority of women overestimate both their own risk and the populations’ risk of developing breast cancer. A number of factors have been found to correlate with perceived risk. Methods This paper reports on a telephone survey of a nationally representative sample of approximately 3,000 Australian women aged 30 to 69 years, conducted in 2007, and compares the findings with those of a similar survey conducted in 2003. Results There was a clear tendency for respondents to overestimate the proportion of women who will develop breast cancer during their lifetime. Approximately half the respondents …


General Practice Registrars: Attitudes Of Older Patients, Andrew D. Bonney, Sandra C. Jones, Lyn Phillipson, Donald C. Iverson Jun 2012

General Practice Registrars: Attitudes Of Older Patients, Andrew D. Bonney, Sandra C. Jones, Lyn Phillipson, Donald C. Iverson

Don C. Iverson

Previous research indicates that older patients may be less willing to consult general practice registrars (GPRs), reducing training opportunities in chronic/complex care. This survey explores older patients’ attitudes in order to inform models of interaction that would be acceptable to patients. METHODS Ten training general practices distributed questionnaires for self completion to 50 patients aged 60 years and over. Chi-square, Spearman’s rho and logistic regression were used for analysis. RESULTS The response rate was 47%. Ninetysix percent wanted ongoing contact with their general practitioner if they saw a GPR. Twenty-four percent were comfortable with GPR chronic/complex care, increasing to 73% …

Design: Therapeutic advertisements in six popular Australian women’s magazines were monitored between April 2006 and March 2007. A subset of advertisements was included in the study based on criteria derived from a definition of DAA. Unique advertisements were analysed by four independent coders. Main outcome measures: Types of advertisements and their sponsors, the types of disease information present, and the persuasive techniques utilised. Results: Of 711 advertisements identified, 60 met the inclusion criteria for DAA, and 30 of these were unique. Over one-third of the advertisements were classified as “unbranded …


Preparing For An Ageing Population: A Survey Of Older Patients' Attitudes To General Practice Registrars, Andrew D. Bonney, Sandra C. Jones, Lyn Phillipson, Donald C. Iverson Jun 2012

Preparing For An Ageing Population: A Survey Of Older Patients' Attitudes To General Practice Registrars, Andrew D. Bonney, Sandra C. Jones, Lyn Phillipson, Donald C. Iverson

Don C. Iverson

The ageing population makes it imperative to provide appropriate training for general practice registrars (GPRs) in the community-based care of older patients. However, data suggest that older patients may be less willing to consult GPRs for chronic/complex care; adversely affecting training opportunities and potentially the satisfaction of older patients in training practices. This cross-sectional study was undertaken to investigate this concern in the Australian context and develop models of older patient-GPR interaction that are acceptable to patients.


Relax, You're Soaking In It: Sources Of Information About Infant Formula, Nina Berry, Sandra Jones, Donald Iverson Jun 2012

Relax, You're Soaking In It: Sources Of Information About Infant Formula, Nina Berry, Sandra Jones, Donald Iverson

Don C. Iverson

Although the advertising of infant and follow-on formula products in Australia is prohibited by the Marketing in Australia of Infant Formulas: Manufacturers and Importers Agreement (1992), toddler milk is advertised without restriction. Recent research suggests that Australian mothers perceive advertisements for toddler milk to also be advertisements for infant formula. Furthermore, they tend to accept the messages they encounter in these advertisements uncritically. This study used established qualitative market research strategies to investigate what mothers, and those who influence mothers, know about formula milk products. This included exploration of commonly used sources of information, how toddler milk advertisements are interpreted …
