Implementation of legislative requirements for emergency medical services in prepaid group practice organizations

This study was based on the concept that intracellular accumulation of calcium plays a role in mediating ischemic myocardial injury and that inhibition of entry of calcium into cells may have a salutary effect on the ischemic heart. Nifedipine, a potent vasodilator and inhibitor of transmembrane calcium flux, was infused into the aortic root of 6 dogs (5 microgram/kg/hr) during 2 hours of myocardial ischemia while on cardiopulmonary bypass. Seven control animals received normal saline at the same flow rate and temperature (20 degrees C). The results showed that none of the 7 control animals were able to maintain adequate aortic pressure or cardiac output after 30 to 60 minutes of normothermic reperfusion. All had marked left ventricular failure and were unresponsive to large doses of inotropic agents. In contrast, the 6 dogs treated with nifedipine were weaned from bypass either without difficulty or requiring small doses of calcium chloride and norepinephrine. Light microscopy demonstrated more marked ischemic damage in the control group than in the group of drug-treated dogs. We conclude that the concept of inhibition of transmembrane calcium flux offers a new and potent method for myocardial preservation during ischemia.     

Consultation patterns in a general practice

A study from the Oxford Community Health Project is reported on the effects on consultation rates in general practice of patients' age, sex, date of registration, address, and usual doctor. The impact on consultation rates of accessibility of surgeries and availability of doctors is examined when the variables are controlled, and the importance of these factors is discussed in relation to planning primary medical care.     

National dermatology manpower requirements: the experience of prepaid group practices

Ten prepaid group health plans across the country were surveyed as part of an effort to estimate the need for dermatologists in the United States. Although generalizing the experiences of prepaid group practices to the general population is at best an imprecise approach, the dramatic shortage suggested by the data cannot be completely ascribed to the method used. Whereas the average ratio in the surveyed plans was 2.8 dermatologists per 100,00 subscribers, there are only about 1.9 dermatologists providing patient care per 100,000 persons in the general population. The difference between prepaid plan subscribers and the general population in annual visits to dermatologists is even more dramatic: 193 per 1,000 subscribers compared to 84 per 1,000 population.     

Clinico-epidemiologic study of the mental state of a group of elderly persons from the general population

A clinico-epidemiological study of a representative group of individuals older than 60 years of age from the general city population demonstrated that by far not all mental disorders of old age come into contact with a psychiatrist. A study of 1020 individuals (361 males and 659 females) detected 23 patients (2.3% of the studied population), who suffered from psychotic conditions and who were not registered in the neurophsychiatric dispensary: 6(0.6%) with schizophrenia, 6 (0.6%) -- with delusional psychoses of old age, 9 (0.9%) -- with vascular and senile psychoses and 2 (0.2%) -- with exogenous -- organic psychoses. Besides, in 29 cases (2.8%) there were signs of expressed organic dementia. In 38.9% of the studied individuals there were different mental abnormalities not attaining a psychotic level (initial weakly pronounced and mild psychoorganic conditions).     

Responsibility to the population in general practice. Three years experiences with a patient-list systems in Norway

A list patient system has been tried out among general practitioners in four Norwegian municipalities for a period of three years. For some of the doctors involved the introduction of such a system led to increased work load due to mismatch between the doctor's work capacity and the number of patients on his/her list. However, the experience from the process of establishing the list provided useful knowledge and showed ways of avoiding similar problems if the system is introduced on a national basis. Waiting time for consultation has been reduced, and access to the doctor by telephone has improved. The demand for emergency on call services has been reduced because the doctors are easier to reach during the day. Patients are satisfied with the system and would like to see it become permanent. Two thirds of the GPs involved in the experiment share this standpoint.     

Psychiatric disorders and medical care utilization among people in the general population who report fatigue

OBJECTIVE: To study the prevalence of fatigue in the general population and its association with psychiatric disorders, somatization, and medical utilization. SETTING: The public-use data tape from the 1984 National Institute of Mental Health Epidemiologic Catchment Area Study. PARTICIPANTS: Household sample of 18,571 subjects. INTERVENTIONS: Structured psychiatric interviews were reviewed to study the prevalence of complaints of current and lifetime fatigue and their relationship to selected psychiatric disorders. RESULTS: Fatigue has high current (6.7%) and lifetime (24.4%) prevalences in the general population. Medically unexplained fatigue also has high current (6.0%) and lifetime (15.5%) prevalences. When compared with those reporting no current fatigue, subjects who reported current (one-month) fatigue were significantly more likely to have experienced current and lifetime episodes of major depression, dysthymic disorder, panic disorder, and somatization disorder. They also had significantly higher mean numbers of lifetime and current DSM-III psychiatric diagnoses, medically unexplained physical symptoms (not just fatigue-related symptoms), and visits to health care providers than did patients without current episodes of fatigue. CONCLUSIONS: The high prevalence of fatigue in the general population appears to be significantly associated with increased lifetime and current risk for affective, anxiety, and somatoform disorders, as well as increased utilization of medical services. These data suggest that assessment of both medical and psychological health may be essential for the proper care of patients with fatigue.     

Nephrology in general practice

Hints for the practitioner concerning the management of patients with renal disease are presented. Important facts relating to history, physical, laboratory and radiological findings are stressed and diagnostic assessment is briefly described. Although the general practitioner will refer such patients in most instances to a nephrologist, he should know what kind of further examinations and studies are necessary for correct diagnosis and adequate treatment. The present therapeutic possibilities have greatly improved, but one still disappointing aspect is the treatment of certain forms of glomerulonephritis. The cumulative survival rates in patients undergoing hemodialysis and renal transplantation are assessed and compared with the survival rates in patients suffering from myocardial infarct and carcinoma of the breast, colon and the lung. Essential preventive measures are avoidance of toxic substances like analgesics and consistent antihypertensive therapy even in patients with a renal ailment. The dosage of drugs which are mainly eliminated by the kidneys must be adapted to renal function (serum creatinine or clearance of endogenous creatinine).     

Somatization in general practice

Patients with unexplained physical symptoms are very common in primary care. Some patients attribute these symptoms to physical disease (somatizing patients). Somatization can be a symptom of psychiatric disorder, which is found in 1/4 to 1/3 of the patients in a primary care setting. This form of somatization makes diagnosing difficult and is the main reason why psychiatric disorders are underdiagnosed. Simple techniques for diagnosing and treating somatizing patients are available to general practitioners. However, to improve diagnostic sensitivity and treatment, further teaching and development in primary care settings are necessary.     

Psoriasis in general practice

This report, based on a resource pack for primary care nurses, describes the features of psoriasis and reviews current prevention and treatments. The pack emphasises the important role of nurses in helping people to maintain their confidence and independence in the face of this chronic disease.
