Factors affecting primary care physician participation in Medicare

OBJECTIVES: This study investigates the levels of participation and the relative association of economic and noneconomic factors on primary care physician participation in the Medicare program. METHODS: Demographic information, participation in Medicare, and attitudes toward both the Medicare program and Medicare patients were collected in a written survey mailed to half the primary care physicians in Iowa. Ordinary least squares and logistic regression analyses were conducted to determine factors associated with the percentage of Medicare patients in a practice and the acceptance of all new Medicare patients, respectively. RESULTS: Two thirds of physicians were accepting all new Medicare patients, whereas 16% were accepting no new Medicare patients. Factors associated with having a higher percentage of Medicare patients in a practice were as follows: (1) a larger proportion of Medicare recipients in the county, (2) practice as a general internal medicine physician, (3) more years in practice at the current location, (4) greater enjoyment treating elderly patients, (5) less concern about having too many Medicare patients, and (6) a stronger belief that the Medicare program respects their professional judgment. Physicians less concerned about having too many Medicare patients in their practice and physicians in counties with a higher percentage of Medicare patients were significantly more likely to accept all new Medicare patients. CONCLUSIONS: These results suggest that as Medicare reforms are discussed, careful consideration of the impact of these reforms on noneconomic issues is important to ensure adequate physician participation and access for elderly patients through the Medicare program.     

Response styles among patients with minor depression and dysthymia in primary care.

Ruminative responses to depression have predicted duration and severity of depressive symptoms. The authors examined how response styles change over the course of treatment for depression and as a function of type of treatment. They also examined the ability of response styles to predict treatment outcome and status at follow-up. Primary care patients (n=96) with dysthymia or minor depression were randomly assigned to problem-solving therapy, paroxetine, or placebo. Patients' depressive symptoms and rumination, but not distraction, decreased over time. Pretreatment rumination and distraction were associated with more depressive symptoms at the conclusion of treatment; the latter finding was not consistent with the response style theory of depression. Results are discussed in terms of their implications for this theory. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The relationship between retirement life cycle changes and older men's labor force participation rates

This study probes the utility of older men's labor force participation rates (LFPRs) as indicators of the work-to-retirement transition. Specific attention is directed at how shifts in the retirement life cycle are related to LFPRs. Based on Current Population Survey data for the 1970s, a life table modeling approach showed that LFPRs are relatively weak indicators of the work-to-retirement transition. This was demonstrated by the relative stability in older men's age profiles of LFPRs despite significant changes in the timing and "organization" of the work-to-retirement transition. The 1970s evidenced a contraction of the main career and the expansion of both post-retirement work activity and retirement, yet none of these changes substantially altered the age profiles of older men's labor force participation rates.

Mental disorders and disability among patients in a primary care group practice

OBJECTIVE: This article examines social and occupational disability associated with several DSM-IV mental disorders in a group of adult primary care outpatients. METHOD: The subjects were 1,001 primary care patients (aged 18-70 years) in a large health maintenance organization. Data on each patient's sociodemographic characteristics and functional disability, including scores on the Sheehan Disability Scale, were collected at the time of a medical visit. A structured diagnostic interview for current DSM-IV disorders was then completed by a mental health professional over the telephone within 4 days of the visit. RESULTS: The most prevalent disorders were phobias (7.7%), major depressive disorder (7.3%), alcohol use disorders (5.2%), generalized anxiety disorder (3.7%), and panic disorder (3.0%). A total of 8.3% of the patients met the criteria for more than one mental disorder. The proportion of patients with co-occurring mental disorders varied by index disorder from 50.0% (alcohol use disorder) to 89.2% (generalized anxiety disorder). Compared with patients who had a single mental disorder, patients with co-occurring disorders reported significantly more disability in social and occupational functioning. After adjustment for other mental disorders and demographic and general health factors, compared with patients with no mental disorder, only patients with major depressive disorder, bipolar disorder, phobias, and substance use disorders had significantly increased disability, as measured by the Sheehan Disability Scale. CONCLUSIONS: Primary care patients with more than one mental disorder are common and highly disabled. Individual mental disorders have distinct patterns of psychiatric comorbidity and disability.     

Untreated anxiety among adult primary care patients in a Health Maintenance Organization

BACKGROUND: Untreated anxiety may be particularly difficult for primary care physicians to recognize and diagnose because there are no reliable demographic or medical profiles for patients with this condition and because these patients present with a high rate of comorbid psychological conditions that complicate selection of treatment. METHOD: A prospective assessment of untreated anxiety symptoms and disorders among primary care patients. RESULTS: Approximately 10% of eligible patients screened in clinic waiting rooms of a mixed-model health maintenance organization reported elevated symptoms and/or disorders of anxiety that were unrecognized and untreated. These patients with untreated anxiety reported significantly worse functioning on both physical and emotional measures than "not anxious" comparison patients; in fact these patients reported reduced functioning levels within ranges that would be expected for patients with chronic physical diseases, such as diabetes and congestive heart failure. The most severe reductions in functioning were reported by untreated patients whose anxiety was mixed with depression symptoms or disorders. CONCLUSION: Primary care physicians may benefit from screening tools and consultations by mental health specialists to assist in recognition and diagnosis of anxiety symptoms and disorders alone and mixed with depression.     

Reduced substance-abuse-related health care costs among voluntary participants in Alcoholics Anonymous

OBJECTIVE: This study examined differences in outcomes, alcoholism treatment utilization, and costs between alcoholic individuals with no previous treatment history who chose to attend Alcoholics Anonymous (AA) or to seek help from a professional outpatient alcoholism treatment provider. METHODS: Participants in this three-year prospective study were recruited at alcoholism information and referral services and at detoxification units in the San Francisco Bay Area. Chi square and t tests and repeated-measures analyses of variance were used to examine data gathered from interviews with 201 participants at baseline and at one and three years. RESULTS: At baseline, participants who chose to attend AA meetings (N = 135) were not significantly different from those who chose professional outpatient treatment (N = 66) in sex, marital status, employment, race, and symptoms of alcohol dependence and depression. However, AA attendees had lower incomes and less education and experienced more adverse consequences of drinking at baseline than did those who sought outpatient care, suggesting somewhat worse prognoses for the AA group. Over the three-year study, per-person treatment costs for the AA group were 45 percent (or $1,826) lower than costs for the outpatient treatment group. Despite the lower costs, outcomes for the AA group at both one and three years were similar to those of the outpatient treatment group. CONCLUSIONS: Voluntary AA participation may significantly reduce professional treatment costs. Clinicians, researchers, and policymakers should recognize the potential health care cost offsets offered by AA and other self-help organizations.     

Reproducibility and accuracy among primary care providers of a screening examination for foot ulcer risk among diabetic patients

The differentiation of granulosa cells is regulated by follicle-stimulating hormone (FSH) and local ovarian factors. To further analyze the role of FSH and activin in this process, we have examined the effect of FSH and activin on FSH and luteinizing hormone/human chorionic gonadotropin (LH/hCG) receptor induction in granulosa cells. Granulosa cells from diethylstilbestrol (DES)-primed immature rats produce activin and maintain FSH receptor without LH/hCG receptor expression in the absence of FSH. On the other hand, FSH induced granulosa cells to differentiate into more mature granulosa cells in which higher LH/hCG receptor expression and diminished activin production were observed.     

Subjective experience and attitudes towards participation in clinical trials among patients with anxiety disorders

Newly recognized rat parvovirus (rat orphan parvovirus: ROPV) was examined for viral excretion and persistence in infected rats, and also for infectivity to mice and hamsters. The virus appeared to replicate mainly in lymphoid or hematopoietic tissues, and was detected in feces, urine and oropharynx of the infected rats at 1 to 4 weeks postinfection. The infective virus was also detected in peripheral leukocytes and various tissues at an acute phase of infection, and decreased in every tissue at 8 weeks postinfection. Viral DNA, however, was persistent in lymphoid tissues at least up to 24 weeks postinfection. When the virus was inoculated to mice and hamsters, no evidence of viral production and antibody response was demonstrated. ROPV is assumed to be a variant of the known rat parvovirus which resulted to alter cell tropism and persist in lymphoid or hematopoietic tissues, in order to escape from host immune system.     

Platelet serotonin in patients with analgesic-induced headache

OBJECTIVE: To determine the effect of area postrema AP on DOCA-salt induced hypertension in rat, with emphasis on renal hemodynamics. METHOD: Blood pressure, salt and water balances and renal hemodynamics were observed in AP ablated and sham-operated rats treated with DOCA-salt. RESULTS: In AP intact (API) rats, after one week of DOCA-salt treatment BP began elevating to statistical significance at the end of the second week (MAP 15.9 +/- 0.7 vs. 13.5 +/- 0.5 kPa), followed by a plateau period from the third to fifth week. In AP ablated (APX) rats, BP raised during the first week of DOCA-salt treatment. However, the elevation gradually disappeared and BP returned to baseline at the fifth week. Sodium balance study showed that DOCA-salt treatment induced significant sodium retention in API rat, while the sodium metabolism remained stable in APX group except in the first week. Basal renal hemodynamic parameters (GFR, RPF, UNaV, UV) were not changed at neither the beginning nor the end of the study. However, a small dose of hypertonic saline (7% NaCl 0.3 ml) injection caused a brisk rising of these four parameters in APX but not API group. CONCLUSION: AP plays an important role in normal salt and water metabolism and might be involved in pathogenesis of DOCA-salt hypertension through regulation for renal hemodynamics and body fluid homeostasis.

The psychological profiles of patients with whiplash-associated headache

Headache often compounds chronic neck pain following whiplash injury. To better understand post-traumatic headache, the SCL-90-R symptom checklist was used to determine the psychological profiles of patients with whiplash-associated headache and of patients with whiplash-associated neck pain without headache. The psychological profiles of these patients were compared with previously published SCL-90-R profiles of patients with post-traumatic and nontraumatic headache, and of the normal population. Patients with whiplash-associated headache were not significantly different from those with other forms of post-traumatic headache or with whiplash-associated neck pain without headache. However, when patients with whiplash-associated headache and patients with nontraumatic headache were compared to normal data, significant differences emerged. Patients with nontraumatic headache exhibited higher scores on all subscales, whereas patients with whiplash-associated headache differed from the normal sample only on somatization, obsessive-compulsive, depression and hostility subscales, and the global severity index. These differences imply that patients with whiplash-associated headache suffer psychological distress secondary to chronic pain and not from tension headache and generalized psychological distress.     

Mental health service use among young children receiving pediatric primary care

OBJECTIVE: To investigate the factors associated with mental health service use among young children. METHOD: Five hundred ten preschool children aged 2 through 5 years were enrolled through 68 primary care physicians, with 388 (76% of the original sample) participating in a second wave of data collection, 12 to 40 months later. Consensus DSM-III-R diagnoses were assigned using best-estimate procedures. The test battery included the Child Behavior Checklist, a developmental evaluation, the Rochester Adaptive Behavior Inventory, and a videotaped play session (preschool children) or structured interviews (older children). At wave 2, mothers completed a survey of mental health services their child had received. RESULTS: In logistic regression models, older children, children with a wave 1 DSM-III-R diagnosis, children with more total behavior problems and family conflict, and children receiving a pediatric referral were more likely to receive mental health services. Among children with a DSM-III-R diagnosis, more mental health services were received by children who were older, white, more impaired, experiencing more family conflict, and referred by a pediatrician. CONCLUSIONS: Young children with more impairment and family conflict are more likely to enter into treatment. Services among young children of different races with diagnoses are not equally distributed. Pediatric referral is an important predictor of service use.     

Specialty choice and understanding of primary care among Japanese medical students

To assess specialty choice and understanding of primary care among Japanese medical students, all students from seven Japanese medical schools (three public and four private) were surveyed, using a written questionnaire. A total of 3377 students provided data for the study. Of the students surveyed, 89.8% wanted to become clinicians, and 79.3% wanted to have general clinical ability. About half of the respondents, 54.9%, replied that they had some, or great, interest in primary care, but it was found that their understanding of primary care was inadequate. Almost half (56.3%) of the students answered that they had some idea of what a general practitioner did. This proportion was nearly the same through all years of medical school. While 1245 (36.9%) students (most of them in the fifth or sixth year) replied that they had received some clinical training while working in hospitals, only 203 (6.0%) students had worked in private clinics (the sites where most primary care is still provided), and 129 (3.8%) students had experience in providing home visits and home care. An even greater number, 64.3%, replied that they had inadequate information about the career options available to them. The study found that although many Japanese medical students want to obtain broad clinical competence, their understanding of primary care is insufficient. In order to increase the number of primary care providers the system of medical education in Japan must provide primary care doctors to act as role models, and must make available information about postgraduate primary care programmes. These programmes need to be increased, as do rewarding positions for programme graduates.     

Working with the primary care physician

In this article, the authors illustrate a model of an effective ongoing and active collaboration among a group of pediatricians and child and adolescent psychiatrists. They demonstrate how regular meetings and active collaborative interventions broadened each other's understanding and treatment of children. The close relationship, trust, and understanding that developed as a result of this project had a marked impact on the treatment provided by both types of specialist. The concept of the developmentally informed pediatrician is the basic tenet of this project, which continues to have important implications for the training and practice of today's pediatricians.     

Reduced renal sodium excretion in primary hypertensive patients after an oral glucose load

This study was designed to determine urinary sodium excretion in response to an oral glucose load in hypertensive patients. Fifteen hypertensive patients and eighteen normotensive subjects were studied after an overnight fast and for 4 h after the ingestion of 100 g glucose. A subgroup of untreated, nonobese, primary hypertensive patients (five of the 15 hypertensive patients) became hyperinsulinemic (total area under the insulin curve [TAUC]: 33,080 +/- 3348 microU ml(-1) 120 min-1) in response to an oral glucose load compared to normotensive subjects (TAUC: 3670 < 13.731 < 23,693 microU ml(-1) 120 min-1) or to be other subgroup of normoinsulinemic hypertensive individuals TAUC: 10,221 +/- 1615 microU ml-1 120 min-1) despite a similar serum glucose concentration in both groups. A significant decrease in renal sodium excretion in the entire hypertensive group (47.1 +/- 4.7%, P < 0.019) compared to the normotensive (20.0 +/- 10.5%) subjects was also observed during the oral glucose tolerance test. Decreased renal sodium excretion was followed by a transient increase in urinary acid excretion. We speculate that the increase in insulin secretion may be responsible for the sodium-dependent increase in intracellular Ca2+, cellular H+ output and blood pressure in a subgroup of salt-sensitive patients with hypertension. New studies should be designed to identify the precise mechanisms involved in the interaction between hypertension, serum insulin-glucose levels and the magnitude of the renal tubule reabsorption abnormality.
