BACKGROUND: In identifying opportunities to improve the quality of stroke prevention in general practice, insight in areas of suboptimal care is essential. This study investigated the quality of care in stroke prevention in general practice and its relation to the occurrence of stroke. METHODS: Retrospective case-based audit with guideline-based review criteria and final judgment of suboptimal care by an expert panel. RESULTS: A total of 292 stroke patients were identified through stroke registers of two main referral hospitals for stroke in Rotterdam. The general practitioners (GPs) (n = 95) of these patients were approached. The overall response rate from GPs was 81%, and a total of 193 patients from 77 GPs were included in the study. Data on the process of care at patient level were collected by chart review and by structured interviews with GPs during site visits. All cases were presented to a six-member panel of GPs and neurologists. In 44% of the cases, suboptimal care was identified (31% judged as possibly or likely failing to prevent stroke). Of the total number of identified shortcomings, 52% was related to inadequate hypertension control, particularly lack of follow-up after established hypertension. Another 17% of identified shortcomings concerned inadequate cardiovascular risk assessment. CONCLUSIONS: A substantial number of shortcomings in care, particularly in the domain of hypertension control and the assessment of patient's risk profiles for cardiovascular disease (CVD), were identified. This study suggests that improving preventive care delivery in general practice could reduce the occurrence of stroke.  相似文献

BACKGROUND: Treatment of nephroblastoma (Wilms tumor) has presently achieved a greater than 80% cure rate. Pathologic stage and grade are considered the most reliable prognostic parameters, but other biologic factors are under study in order to improve patient stratification into risk groups. Correlation of elevated levels of the lipogenic enzyme fatty acid synthase (FAS) with aggressiveness of some cancers has drawn attention to this enzyme as a possible marker of poor prognosis. PROCEDURE: To determine the predictive strength of FAS expression in Wilms tumor (with particular emphasis on intermediate risk, i.e., non anaplastic tumors, the vast majority of nephroblastomas), we evaluated immunostaining expression in archival specimens from 94 neoplasms. The degree of expression was correlated with stage, grade, clinical course and administration of prenephrectomy chemotherapy. RESULTS: Expression of FAS increased in anaplastic tumors (P = 0.043) and higher stages (P = 0.029). FAS expression correlated with OS and DFS at both univariate and multivariate analysis. Comparable results were obtained when analyzing the intermediate risk population separately. Pretreatment resulted in an increased FAS expression, without reaching significance level (P = 0.059). CONCLUSIONS: Expression of FAS might be an independent prognostic factor, particularly for intermediate-risk patients. The blockade of fatty acid synthesis by inhibition of FAS enzymatic function by means of metabolic analogues might prove a novel target pathway for the treatment of nephroblastoma.  相似文献

We carried out five cross sectional surveys between 1993 and 1994 to assess the epidemiology of malaria in the village of Bancoumana, located in the Sudanese savannah areas of Mali. Each survey included a collection of entomological, clinical, parasitological and immunological data. The study population involved 1600 children from six months to 9 years of age. The main vector was Anopheles gambiae s.l., man bite rate and entomological inoculation rate were maximum respectively in August (peak of the transmission season) and October (end of transmission season). Plasmodium. falciparum was the main parasite species observed. Spleen enlargement rate, parasite rate, gametocyte rate and parasite density varied significantly with age and season. The parasite rate, gametocyte rate and parasite density were significantly low in October 1994 compared with October 1993 while the entomologic parameter did not show any variation over the two years. This reduction of parasitologic index between 1993 and 1994 may be related to an increase of anti-malarial drug use in the population. Our results show that malaria is hyperendemic in the village of Bancoumana.  相似文献

Masticatory muscle electromyograms (EMGs) were recorded while patients with bulbar myasthenia gravis chewed artificial food and compared with those of patients with ocular myasthenia gravis, patients in clinical remission who had previously suffered from bulbar myasthenia gravis and healthy individuals. Masticatory performance and EMGs were significantly smaller in the bulbar group. There were no indications of subclinical masticatory muscle weakness in patients with bulbar myasthenia gravis in remission and in patients with ocular myasthenia gravis. Patients with bulbar myasthenia gravis barely compensated for muscular weakness by chewing at a higher percentage of their maximal EMG. These quantitative findings, when combined with subjective reports of masticatory muscle weakness, show that a need to support the jaw is characteristic of patients with bulbar myasthenia gravis who produce low EMG activity.  相似文献

OBJECTIVE: Nowadays, registration of patient data on paper is gradually being replaced by registration using an intensive care information system (ICIS). The aim of this study was to evaluate the effect of the use of an ICIS on nursing activity. DESIGN: Randomized controlled trial with a crossover design. SETTING: An 18-bed medical-surgical ICU in a teaching hospital. PATIENTS, NURSES AND INTERVENTIONS: During a 6week period 145 consecutive adult patients admitted to the ICU after uncomplicated cardiothoracic surgery were randomized into two groups: for one group the documentation was carried out using a paper-based registration (Paper), in the second group an ICIS was used for documentation. MEASUREMENTS AND RESULTS: The nursing activities for these patients were studied during two separate periods: the admission period and the registration phase (the period directly following the admission procedure). The duration of the admission procedure was measured by time-motion analysis and the nursing activities in the registration phase were studied by work sampling methodology. All nursing activities during the registration phase were grouped in four main categories: patient care, documentation, unit-related and personal time. The duration of the admission procedure was longer in the ICIS group (18.1+/-4.1 versus 16.8+/-3.1 min, p<0.05). In the registration phase, a 30% reduction in documentation time (Paper 20.5% of total nursing time versus ICIS 14.4%, p<0.001), corresponding to 29 min (per 8h nursing shift) was achieved. This time was completely re-allocated to patient care. CONCLUSIONS: The use of the present ICIS in patients after cardiothoracic surgery alters nursing activity; it reduces the time for documentation and increases the time devoted to patient care.
