A marked proportion of primary care patients have mental disorders and problems that remain unrecognized by the patients and their general practitioners. There is furthermore a great variation in the physicians’ ability to detect mental disorders. The aim of the present study was to find out the overall prevalence of mental disorders among patients receiving primary health care. The material consisted of 1000 randomly selected adult patients attending primary care facilities in Turku. The mental disorders were assessed by using the Symptom Checklist (SCL-25) and by general practitioners. According to the SCL-25, one fourth of the sample had a mental disorder. Only two fifths of them could be identified by the general practitioners.  相似文献

The characteristics of all the paediatric admissions made to a district general hospital over a three-year period were analysed in this study. Paediatric admissions averaged 23 per year (10% of the total admissions to the unit over that time). The mean age was six years, median age was four years. Sixty-two per cent were medical admissions and 38% surgical. Forty-seven per cent of the surgical admissions involved head injuries. Seventy-four per cent of medical admissions were directly related to upper and lower airway problems. Mean total admission time was six days, with a median of two days. Fifty-nine per cent (40) of all cases required intubation for a mean period of five days (median = three days). All cases were PRISM scored (Pollack, Ruttimann & Getson 1988). The mean score was 8. Ninety-four percent of admissions surviving to go home. There were a total of four deaths over the three-year period. The PRISM scores of those who died had a mean of 30, which was significantly different (P < 0.05) from the survivors who had a mean PRISM score of six and a median of four. The organs of one of the nonsurvivors were transplanted. Currently there is considerable interest in the feasibility of transferring all paediatric intensive care patients to a regional centre, the consequences of such a policy must be carefully assessed if its implementation is to be a success.  相似文献

Abstract Economic factors in diagnosis and treatment planning in periodontology may be considered from several points of view. A first perspective is that of government responsibility. Because of the explosion in health care expenditure in the last decade, public funding of dental care programmes may become static or even reduced. Most governments try to curb the ever growing public health expenditure. Consequently, terms like effectiveness, efficiency and accountability are now becoming common words also in relation to periodontal health care. Moreover, private insurance companies, which have entered this area, may be individual patient who, explicitly or implicitly, would like to consider the services individual patient, who explicitly or implicitly, would like to consider the sendees rendered in periodontal therapy and prevention as cost-effective. Features of supply of and demand for care on an individual basis should also be considered. Finally, the periodontist or general practitioner has to consider economic factors. In professional life, there should be a balance between good working conditions providing satisfactory care, and the demands and priorities of individual patients and the community at large.  相似文献

OBJECTIVE: The 5-year project in the province of Sofala was designed to improve access, quality and utilization of emergency obstetric care (EmOC) by strengthening rural hospitals and health centers and ultimately the health system's capacity to respond to emergencies more quickly and effectively. METHODS: Implementation consisted of attention to infrastructure, human resource development, transportation and communication systems, and management. Specific management aspects that were targeted for improvement included: supportive supervision, logistics for supplies, equipment and drugs, record keeping, monitoring and evaluation, and quality improvement techniques such as maternal death audits. RESULTS: Access to EmOC improved with an increase in the number of fully functional EmOC facilities from 4 to 18. The number of women with obstetric complications who were admitted for treatment in participating facilities tripled, and the proportion of those women dying declined by half. CONCLUSIONS: Close collaboration and partnership with the provincial health directorate make the sustainability of many results likely while the replication of much of the Sofala model to other provinces is promising for the national strategy to reduce maternal mortality.  相似文献

The Multiphasic Environmental Assessment Procedure (MEAP; Moos and Lemke, 1984) was used to assess three long-stay settings within a geriatric hospital, one of which is a non-nursing unit committed to the philosophy of residents viewing the setting as their own home. Findings suggest positive outcomes for residents on the nonnursing unit, and support the view that types of care fostering independence and personal responsibility of elderly residents in their setting may be associated with increased mental functioning and activity. The lack of trained nursing staff had no detrimental effect on any measure of resident life, and some specific caring practices on the unit may be interpreted as having a positive outcome for residents.  相似文献

AIMS: To characterize the determinants of diabetes-related emotional distress by treatment modality (diet only, oral medication only, or insulin). METHODS: A total of 815 primary care patients with Type 2 diabetes completed the Problem Areas in Diabetes (PAID) Scale and other questions. We linked survey data to a diabetes clinical research database and used linear regression models to assess the associations of treatment with PAID score. RESULTS: PAID scores were significantly higher among insulin-treated (24.6) compared with oral-treated (17.8, P < 0.001) or diet-treated patients (14.7, P < 0.001), but not different between oral- vs. diet-treated patients (P = 0.2). Group scores remained similar, but the statistical significance of their differences was reduced and ultimately eliminated after sequential adjustment for diabetes severity, HbA(1c), body mass index, regimen adherence, and self-blood-glucose monitoring. Insulin-treated patients reported significantly higher distress than oral- or diet-treated patients on 16 of 20 PAID items. 'Worrying about the future' and 'guilt/anxiety when ... off track with diabetes' were the top two serious problems (PAID >or= 5) in all treatment groups. Not accepting diabetes diagnosis was a top concern for oral- and diet-treated patients, and unclear management goals distressed diet-treated patients. CONCLUSIONS: Primary care patients treated with insulin reported higher diabetes-related emotional distress compared with oral- or diet-treated patients. Greater distress was largely explained by greater disease severity and self-care burdens. To improve diabetes-specific quality of life, clinicians should address patients' sense of worry and guilt, uncertain acceptance of diabetes diagnosis, and unclear treatment goals.  相似文献
