The Development And Management Of A Primary Care Research Network, 1978-87, Donald Iverson, B Calonge, R Miller, L Niebauer, F Reed

Don C. Iverson

The Ambulatory Sentinel Practice Network (ASPN) was created to increase the knowledge of primary care. Building on the experiences of other national and regional primary care research networks, ASPN has evolved as a North American network including practices in 25 U.S. states and four Canadian provinces in 1987. This paper summarizes ASPN's growth and development since 1978, the involvement of the ASPN practices, and the mechanisms used in developing and managing studies.


The Promotion Of Physical Activity In The United States, Donald Iverson, Jonathan Fielding, Richard Crow, Gregory Christenson Jun 2012

The Promotion Of Physical Activity In The United States, Donald Iverson, Jonathan Fielding, Richard Crow, Gregory Christenson

Don C. Iverson

While the medical care encounter is considered an ideal situation in which patients are encouraged to increase their physical activity levels, very little research has been conducted in this setting. In fact, with the exception of the physical activity components of cardiac rehabilitation programs, few formal physical activity programs are available in medical care settings. Although the workplace is currently the focus of the greatest interest by those persons who implement physical activity programs, there is little precision in defining what constitutes a worksite physical activity program. A number of researchers and authors, using program experience rather than empirical findings, …

The nation's schools could contribute significantly and measurably toward improving the health of all Americans, if school health professionals, individually as well as within their various organizations, could …


Health Behavior Models Compared, P Mullen, James Hersey, Donald Iverson Jun 2012

Health Behavior Models Compared, P Mullen, James Hersey, Donald Iverson

Don C. Iverson

This study compares the health belief, Fishbein/Ajzen, and PRECEDE models to predict changes in smoking, exercise, and consumption of sweet and fried foods over an eight-month interval. Data were collected from a panel of 326 adults in two large cities of the western United States. The PRECEDE model accounted for more variance in behavior than both the Fishbein/Ajzen and health belief models, but it required far more questions. Fishbein/Ajzen and PRECEDE provide a limited theoretical basis for selecting specific types of beliefs or predisposing factors without turning to the health belief model, making the health belief model complementary to either …

Using Interviews And Peer Pairs To Better Understand How School Environments Affect Young Children's Playground Physical Activity Levels: A Qualitative Study, Anne-Maree Parrish, Heather Yeatman, Donald Iverson, Ken Russell

Don C. Iverson

School break times provide a daily opportunity for children to be active; however, research indicates this time is underutilized. Reasons for low children’s playground activity levels have primarily focused on physical barriers. This research aimed to contribute to physical environmental findings affecting children’s playground physical activity levels by identifying additional variables through the interview process. Thirteen public schools were included in the sample (total 2946 children). Physical activity and environmental data were collected over 3 days. Environmental variables were manually assessed at each of the 13 schools. Observational data were used to determine which three schools were the most and …

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 …

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

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 …
