The impact of community mental health centers on the utilization of psychiatric services in Monroe County, New York, was evaluated by means of data from the Monroe County Psychiatric Case Register. The catchment areas that received centers served as their own controls. In addition, yearly utilization rates were compared for areas that obtained centers with those remaining centerless. Utilization rates increased markedly in catchment areas with centers, while the percentage of patients seen at the Rochester Psychiatric Center decreased from all catchment areas. Community mental health centers increased the utilization rates of the poor, children, and young adults, while the treatment needs of patient subgroups such as alcoholics, drug addicts, and the elderly were last to be addressed. The data do not evaluate issues such as the character, quality, and effectiveness of care. 相似文献

OBJECTIVES: The objective of this study was to determine the inpatient and care pathway predictive factors of week hospitalization (week-end excluded = HDS) compared to classical short term hospitalization (HC). METHODS: We compared 340 HDS stays to 65 HC stays. We analyzed the major in-patient sociodemographic and medical characteristics, and their care pathways. RESULTS: HDS inpatients were younger, more living in couples, had a higher educational level, better social insurance, more cancer, less associated diagnosis, less general health impairment than HC in-patients. More chemotherapies and endoscopies were performed in HDS. Hospital physicians were more often involved in HDS admissions than in HC admissions and general practitioners were more often involved in outpatient hospital visits for advice before HDS hospitalization than before HC hospitalization. HDS hospitalizations per in-patient were more numerous than HC hospitalizations. HDS inpatients were discharged directly to their home more often. After logistic regression modeling, most of these factors remained independently associated with HDS hospitalization, except for sociodemographic characteristics, age excluded, admission rates and home discharge. CONCLUSIONS: Type of hospitalization (HDS vs. HC) was mainly determined by medical characteristics of patients and by care pathways. Limiting factors were mainly due to organization of care. 相似文献

The experiments were carried out with maize (Zea mays L.) seedlings, hybrid Kneja 530, grown hydroponically in a growth chamber. Twelve-day-old plants were foliar treated with putrescine, N1-(2-chloro-4-pyridyl)-N2-phenylurea (4-PU-30), and abscisic acid (ABA) at concentrations of 10(-5) m. Twenty-four hours later the plants were subjected to a water deficit program, induced by 15% polyethylene glycol (PEG; molecular weight, 6,000). Three days after drought stress half of the plants were transferred to nutrient solution for the next 3 days. The effects of the water shortage, rewatering, and plant growth regulator (PGR) treatment on the fresh and dry weights, leaf pigment content, proline level, relative water content (RWC), transpiration rate, activities of catalase and guaiacol peroxidase, hydrogen peroxide content, and level of the products of lipid peroxidation were studied. It was established that the application of PGRs alleviated to some extent the plant damage provoked by PEG stress. At the end of the water shortage program the plants treated with these PGRs possessed higher fresh weight than drought-subjected control seedlings. It was found also that putrescine increased the dry weight of plants. Under drought, the RWC and transpiration rate of seedlings declined, but PGR treatment reduced these effects. The accumulation of free proline, malondialdehyde, and hydrogen peroxide was prevented in PGR-treated plants compared with the water stress control. The results provided further information about the influence of putrescine, 4-PU-30, and ABA on maize plants grown under normal, drought, and rewatering conditions. Key Words.

BACKGROUND: Like other areas of health care, critical care faces increasing pressure to improve the quality while reducing the cost of care. Strategies drawn from the literature and the authors' experiences are presented. STRATEGIES AND OPPORTUNITIES FOR IMPROVEMENTS: Ten process- or structure-related areas are targeted as strategically important focuses of improvement: (1) restructuring administrative lines to better suit key processes; (2) physician leadership in critical care units; (3) management training for critical care managers; (4) triage; (5) multidisciplinary critical care; (6) standardization of care; (7) developing alternatives to critical care units; (8) timeliness of care delivery; (9) appropriate use of critical care resources; and (10) tracking quality improvement. TIMELINESS OF CARE DELIVERY: Whatever the root cause(s) of unnecessary delays, the result is inefficient use of critical care resources-and ultimately either a need for more resources or longer wait times. Innovations designed to reduce wait times and waste, such as the establishment of a microchemistry stat laboratory, may prove valuable. APPROPRIATE USE OF CRITICAL CARE RESOURCES: Possible strategies for the appropriate use of critical care resources include better selection of well-informed patients who undergo procedures. Reduction in variation among physicians and organizations in providing therapies will also likely lead to a reduction in some high-risk procedures offering little or no benefit, and therefore a reduction in need for critical care services. Better preparation of patients and families should also make end-of-life decisions easier when questions of "futility" arise. Better information on outcomes and cost-effectiveness and consensus on withdrawal of critical care treatments represent two additional strategies. 相似文献

OBJECTIVES: This article provides an overview of patients who were hospitalized in 1993/94 because of acute myocardial infarction (AMI) and projects how many AMI patients there could be in the future. DATA SOURCE: The Person-Oriented Information Data Base was used for this analysis. ANALYTICAL TECHNIQUES: Hospital inpatients who had a primary diagnosis of AMI were analyzed, as well as their subsequent hospitalizations for coronary heart disease in the fiscal year. The age-sex specific hospitalization rates were used with population projections to estimate future hospital use. MAIN RESULTS: Of the nearly 45,000 Canadians who were discharged from hospital in 1993/94 with a primary diagnosis of AMI, most (72%) had only one hospital stay within the fiscal year, but 18% had two related stays, and 10% had three or more. AMI patients were hospitalized an average of 14.6 days. The projected number of AMI patients and the number of hospital days used will increase by approximately 36% each decade to the year 2026. 相似文献

Two Eucalyptus homologues of the Arabidopsis floral homeotic gene AP1 (EAP1 and EAP2) show 60-65% homology to AP1. EAP1 and EAP2 are expressed predominantly in flower buds. EAP2 produces two different polypeptides arising from differential splicing at an intron, the shorter EAP2 protein diverging from the longer sequence after amino acid 197 and having a translation stop after residue 206. This truncated protein includes both MADS- and K-box amino acid sequences. Ectopic expression of the EAP1 or either of the two EAP2 polypeptides in Arabidopsis driven by the 35S promoter produces effects similar to the corresponding AP1 construct, causing plants to flower earlier, have shorter bolts and resemble the terminal flower mutant (tfl). 相似文献

Thirty-three patients with cerebral palsy had iliopsoas transfers as part of their surgery for hip instability. All had total-body involvement, spastic cerebral palsy and none could walk. At the time of surgery, eight hips were subluxated and 39 were dislocated or severely subluxated. Mean follow-up was 8 years in patients between 8-25 years old. Forty-five of the 47 hips were located. Thirty patients had an accompanying scoliosis, and, in 10 patients, the rib cage impinged on the pelvis. Hip flexion had decreased in most patients. Sitting ability had not improved in any patient, and had in fact deteriorated in 50%. 相似文献

For the past several years, the hospitalization and care of complex nursing care patients (CNCP) has caused concern among organizers, funders and care-givers of the geriatric hospitalization system (GHS). To assist in improving efficiency of the GHS and to address the lack of comprehensive, empirical and up-to-date information on these patients, we conducted a survey to characterize CNCP, to assess their medical problems and to determine their prevalence among the patients in GHS. The survey was conducted in 1994 using a day census. Data were collected on the 2,319 patients in geriatric beds in all the general hospitals and geriatric hospitals in Israel on the day of the survey. 28% of the patients in the GHS were CNCP and a quarter of them (7% of all patients) suffered from more than 1 medical condition. Tube feeding was the most prevalent condition (13% of all patients), followed by terminal illness (9%), deep pressure sores (7%) and intravenous transfusion for more than 3 days (6%). The 80% of the CNCP were hospitalized in geriatric hospitals, primarily in geriatric rehabilitation wards. Their average length of stay was over a year. Internal medicine wards of general hospitals were the most frequent source of patient referral. The survey's findings raise issues related to the organization of care of CNCP. They may serve as a basis for the reorganization of the geriatric hospitalization system in order to improve efficiency and quality of care for the benefit of patients, their families and services providers. 相似文献

Increased antiphospholipid antibody prevalence has been demonstrated by a number of recent studies in in-vitro fertilization (IVF) patients but the potential effects of antiphospholipid antibodies on the different components of the reproductive process and the consideration of whether to test IVF patients for antiphospholipid antibodies are controversial. The present study was undertaken to investigate the possible association between the presence of circulating antiphospholipid antibodies (namely the lupus anticoagulant and anticardiolipin antibodies), among a series of 21 consecutive IVF patients having a clinical spontaneous abortion after their first embryo transfer. As a control group (n=42), the nearest IVF cycle resulting in an ongoing pregnancy before and after each miscarried IVF cycle (i.e. the closest cycles in temporal relationship to the index cycle) was used. One patient (4.8%) in the study group and two women (4.8%) among controls were seropositive for antiphospholipid antibodies. These low and similar seropositivity rates found in the two groups studied lead us to conclude that antiphospholipid antibodies testing in IVF patients should be considered only in those women having repeated failures of implantation/clinical abortion after embryo transfer but not in an infertile general population reaching an IVF programme. 相似文献

PURPOSE: Patients with critical carotid artery stenoses have been considered to be at high risk for carotid artery occlusion necessitating urgent or emergency endarterectomy once the stenosis is identified. Included in this group of patients are those with carotid string sign or atheromatous pseudoocclusion (APO). This review was conducted to determine the impact of the severity of stenosis including APO on the treatment and outcome of patients undergoing carotid endarterectomy. METHODS: The records of 203 consecutive carotid endarterectomies performed in 197 patients were reviewed in detail. Patients were stratified into a critical stenosis group (80% to 99% diameter) and noncritical stenosis group based on noninvasive vascular laboratory and carotid arteriography results. Comparisons were performed of demographic data, atherosclerotic risk factors, carotid artery disease presentation, interval between arteriography and endarterectomy, operative details, and surgical results between the critical and noncritical groups and between patients in the critical group with and without APO. RESULTS: Carotid endarterectomies were performed on 91 critical carotid artery stenoses and 112 noncritical stenoses. The groups did not differ significantly with regards to demographics, risk factors, carotid artery disease presentation, mean back pressure, and operative use of shunt or patch closure. For the critical group the interval between arteriography and endarterectomy was 8.63 +/- 2.38 days compared with 9.64 +/- 2.14 days for the noncritical group (mean +/- SEM, p = 0.75). No patient in either group progressed to occlusion in the interval between arteriography and endarterectomy. Perioperative strokes occurred in two patients (2%) in the critical group and four patients (3.6%) in the noncritical group (p = 0.09). Likewise, no significant difference was demonstrated in these variables when comparing patients with critical carotid artery stenosis and APO with those without APO. CONCLUSIONS: The presence of a critical carotid artery stenosis including APO did not impact on the treatment or outcome of patients requiring endarterectomy nor did it imply the need for emergency intervention to prevent thrombosis. Surgical intervention can proceed after evaluation and optimization of comorbid conditions without undue concern for interval thrombosis. 相似文献

Between January 1, 1987, and December 31, 1992, 140 community-dwelling geriatric patients > or = 65 years of age with a displaced femoral neck fracture (Garden III-IV) underwent primary prosthetic replacement and were followed prospectively for a minimum of 1 year. Overall, 92 patients received a cemented bipolar prosthesis and 48 patients received a cemented modular unipolar prosthesis. There were no statistically significant differences between the two groups with respect to preinjury characteristics (age, sex, and number and severity of medical comorbidities) and functional ability. There were no statistically significant differences between the two groups with regard to the number of postoperative complications, length of stay, and 1 year mortality rate. An in-depth functional evaluation was obtained as follows: level of ambulation, independence in basic activities of daily living (feeding, bathing, dressing, toileting), and independence in instrumental activities of daily living (food shopping, food preparation, banking, laundry, housework, and use of public transportation). At 1 year follow-up, no statistically significant differences in functional ability were identified between the unipolar and bipolar groups. Furthermore, at a minimum of 1 year follow-up, there were no statistically significant differences between the two groups with regard to the need for revision surgery or the incidence hip pain. Based on the results of this study, there does not appear to be any advantage to the use of bipolar endoprosthesis for the treatment of femoral neck fractures in the elderly patient. The lower cost of modular unipolar prostheses compared with bipolar prostheses provides additional support for their use. 相似文献

This investigation tested a program to reduce women's risk for sexual revictimization. Participants were 66 women with histories of sexual victimization as adolescents or adults who were randomly assigned to a preventive intervention group or a no-treatment control group. They completed initial measures assessing history of sexual assault, self-efficacy, and psychological functioning, returning approximately 2 months later for follow-up assessment using the same measures. Results suggest that the prevention program may be effective in reducing the incidence of sexual assault revictimization in this population. In addition, participants in the intervention group displayed significant improvement in psychological adjustment and self-reported self-efficacy.
