ABSTRACT: This study compared in one data set the relative importance of most previously examined risk factors for different symptoms of insomnia.
Data were obtained from personal interviews of 1,588 adults in a rural area. Statistical methods evaluated the association of 42 risk factors with any insomnia and each of four insomnia subtypes: difficulty with initiating sleep (DIS), difficulty maintaining sleep (DMS), early morning awakening (EMA), and restless sleep (RS).
Insomnia rates were greater in this rural population than most U.S. studies and greater in the United States than other countries. The correlations between insomnia subtype and energy level was highest for RS, -0.29, and lowest for EMA, -0.11. All sleep disturbances increased monotonically with depressive symptoms, but the increase was greatest for RS (r = 0.57) and weakest for EMA (r = 0.24). Anxiety and pain also were independently associated with each insomnia subtype. Insomnia problems of spouses were uncorrelated. Other risk factors were independently associated with some insomnia subtypes but not others. For example, the association of age with difficulty maintaining sleep was independent of health measures.
The results suggest that different insomnias have different rates and risk factors and therefore possibly different etiologies and management strategies.

ABSTRACT: A growing body of epidemiological evidence suggests an association between short sleep duration and obesity. Recently, potential hormonal links have been observed that may account for the relationship. The possible connection between sleep duration and body mass index (BMI) has not been explored in rural populations. Rural populations are of interest because obesity rates are high and lifestyle patterns of nutrition, physical activity, work hours, and sleep may differ from those in urban and suburban populations. We conducted this study to determine whether short sleep duration is related to BMI and obesity in a rural population in southeast Iowa.
We conducted a cross-sectional analysis of data collected in the Keokuk County Rural Health Cohort Study, 1999-2004. Study participants were from a population-based sample consisting of 990 employed adults in a rural community in southeastern Iowa. The main outcome measure was BMI. Multiple linear regression modeling was used to adjust for potential confounding variables.
Self-reported sleep duration on weeknights was negatively correlated (beta = -0.42; 95% confidence interval, -0.77 to -0.07) with higher BMI after adjusting for sex, age, educational achievement, physical job demand, household income, depressive symptoms, marital status, alcohol consumption, and snoring.
These data support an association between short sleep duration and higher BMI in this rural population, which is consistent with the relationship found in other settings.

ABSTRACT: Evidence-based public health (EBPH) has been proposed as a practice model that builds upon the success of evidence-based medicine (EBM). EBM has been described as a more scientific and systematic approach to the practice of medicine. It has enhanced medical training and practice in many settings. Both EBM and EBPH systematically use data, information, and scientific principles to enhance clinical care and population health, respectively. In this paper, we review the evolution of EBPH, propose a new definition for EBPH, and discuss developments that may support its further advancement.

ABSTRACT: There has been increasing attention devoted to patient safety. However, the focus has been on system improvements rather than individual physician performance issues. The purpose of this study was to determine if there is an association between certain physician characteristics and the likelihood of medical board-imposed discipline.
Unmatched, case-control study of 890 physicians disciplined by the Medical Board of California between July 1, 1998, and June 30, 2001, compared with 2981 randomly selected, nondisciplined controls. Odds ratios (ORs) were calculated for physician discipline with respect to age, sex, board certification, international medical school education, and specialty.
Male sex (OR, 2.76; P<.001), lack of board certification (OR, 2.22; P<.001), increasing age (OR, 1.64; P<.001), and international medical school education (OR, 1.36; P<.001) were associated with an elevated risk for disciplinary action that included license revocation, practice suspension, probation, and public reprimand. The following specialties had an increased risk for discipline compared with internal medicine: family practice (OR, 1.68; P =.002); general practice (OR, 1.97, P =.001); obstetrics and gynecology (OR, 2.25; P<.001); and psychiatry (OR, 1.87; P<.001). Physicians in pediatrics (OR, 0.62; P =.001) and radiology (OR, 0.36; P<.001) were less likely to receive discipline compared with those in internal medicine.
Certain physician characteristics and medical specialties are associated with an increased likelihood of discipline.

ABSTRACT: To determine if medical students who demonstrate unprofessional behavior in medical school are more likely to have subsequent state board disciplinary action.
A case-control study was conducted of all University of California, San Francisco, School of Medicine graduates disciplined by the Medical Board of California from 1990-2000 (68). Control graduates (196) were matched by medical school graduation year and specialty choice. Predictor variables were male gender, undergraduate grade point average, Medical College Admission Test scores, medical school grades, National Board of Medical Examiner Part 1 scores, and negative excerpts describing unprofessional behavior from course evaluation forms, dean's letter of recommendation for residencies, and administrative correspondence. Negative excerpts were scored for severity (Good/Trace versus Concern/Problem/Extreme). The outcome variable was state board disciplinary action.
The alumni graduated between 1943 and 1989. Ninety-five percent of the disciplinary actions were for deficiencies in professionalism. The prevalence of Concern/Problem/Extreme excerpts in the cases was 38% and 19% in controls. Logistic regression analysis showed that disciplined physicians were more likely to have Concern/Problem/Extreme excerpts in their medical school file (odds ratio, 2.15; 95% confidence interval, 1.15-4.02; p =.02). The remaining variables were not associated with disciplinary action.
Problematic behavior in medical school is associated with subsequent disciplinary action by a state medical board. Professionalism is an essential competency that must be demonstrated for a student to graduate from medical school.

ABSTRACT: Family physicians play a key role in assessing and managing patients with Alzheimer's disease and in linking the families of these patients to supportive services within the community. As part of comprehensive management, the family physician may be responsible for coordinating assessments of patient function, cognition, comorbid medical conditions, disorders of mood and emotion, and caregiver status. Suggestions for easily administered and scored assessment tools are provided, and practical tips are given for supporting primary caregivers, thereby increasing efficiency and quality of care for patients with Alzheimer's disease.

ABSTRACT: Once the clinical diagnosis of Alzheimer's disease has been made, a treatment plan must be developed. This plan should include cholinesterase inhibitor therapy to temporarily improve cognition or slow the rate of cognitive decline, management of comorbid conditions, treatment of behavioral symptoms and mood disorders, provision of support and resources for patient and caregiver, and compliance with state-mandated reporting requirements for driving impairment and elder abuse. The primary caregiver can be a valuable ally in communication, management of care, and implementation of the care plan. Patient symptoms and care needs change as Alzheimer's disease progresses. In the early stage of the disease, the family physician should discuss realistic expectations for drug therapy, solicit patient and family preferences on future care choices, and assist with advance planning for future care challenges. In the middle stage, the patient may exhibit behavioral symptoms that upset the caregiver and are difficult to manage. When the patient is in the advanced stage of Alzheimer's disease, the caregiver may need support to provide for activities of daily living, help in making a difficult placement decision, and guidance in considering terminal care options. Throughout the course of the disease, routine use of community resources allows care to be provided by a network of professionals, many of whom will be specialists in Alzheimer's disease.
