Candidaemia: a 10-year study in an Indian teaching hospital 总被引:3,自引:0,他引:3
Retrospective evaluation of candidaemia patients was performed in an Indian teaching hospital over a 10-year period. The incidence of patients with candidaemia increased eleven-fold in the second half of the study period (55 patients) compared with the first half (5 patients). Haematological malignancies (11 patients), neonatal septicaemia (9), cardiac abnormalities and cardiac surgery (9) were the commonest underlying diseases in these patients. Candida albicans (50%), C. guilliermondii (17%), C. tropicalis (15%) and C. parapsilosis (8%) were the most common fungal pathogens isolated from blood culture. Therapy with two or more antibiotics (92%), corticosteroid administration (25%), intravascular catheter use for over 24 h (78%) and neutropenia (48%) were the accountable predisposing factors. Prolonged hospitalization (mean average 22.2 days as compared with 11.2 days in other patients) was an added risk factor in these patients. 相似文献

Abstract We investigated factors correlated with abnormal behavior in the elderly residing in a special nursing home (group A) and a psychiatric hospital (group B) using the dementia behavior disturbance scale, the mini mental state examination, the Japanese version of the Philadelphia Geriatric Center morale scale, and the ADL assessment scale. The cognitive function of group B was decreased compared with that of group A, but most activities of daily living (ADL) in the latter group were disrupted compared with those in the former. Only a few categories of ADL correlated with abnormal behavior in group A, whereas cognitive function, quality of life, and most categories of ADL correlated with abnormal behavior in group B. These results suggest that factors correlated with abnormal behavior in the elderly differ within institutions of medical and social welfare systems. 相似文献

腹部多脏器损伤的救治 总被引:1,自引:0,他引:1
报告了腹部多脏器损伤158例的救治情况。致伤因素中交通事故和高空坠落伤占67.0%,抢救存活132例,存活率83.5%;死亡26例,病死率16.5%。作者分析了病死率与致伤暴力强、现场急救延误、就诊时间及受伤的脏器数的密切关系。作者认为院前救护、院内正确诊断、及时治疗、果断手术是抢救成功的重要环节;术中应仔细探查、止血,术后应注意防治多脏器衰竭的发生。 相似文献

临床医师处方抗菌药物前需思考的几个问题 总被引:20,自引:0,他引:20
2001年和2003年卫生部全国医院感染监测网调查结果均显示,医院横断面抗菌药物的平均使用率在54%以上,联合用药较为普遍.国内监测结果也表明细菌耐药性日益严重.针对上述问题,提出临床医师在面对病人开处方抗菌药物之前,须思考的问题:是否有使用抗菌药物的适用症?是否了解选用的抗菌药物,选用何种药物?是否有联合使用抗菌药物的指征?采用何种给药途径、给药剂量、给药时间?是否属于特殊宿主或针对特殊病原体的感染使用抗菌药物?密切观察抗菌药物治疗是否有效?针对局部感染是否需要穿刺或外科手术引流病灶?是否已出现抗菌药物的不良反应?是否存在药物相互作用?是否存在不合理使用抗菌药物情况?并且针对每个问题提出了建议. 相似文献

After introducing the context in which health systems exist in developing as well as in industrialized countries, the author describes the role that hospitals are expected to play as 'enterprises'. The rationale behind such a role is explored and the experience so far available discussed. Evidence from several developing countries suggests caution and tends to discourage radical and indiscriminate introduction of market‐oriented reforms, which international donors seem to be spearheading in Africa's health systems. It is likely, however, that a limited, gradual introduction of selected elements of these reforms (such as some aspects of contracting out, managerial decentralization, the split between purchasing and providing functions) may find its place and eventually have a positive impact on the performance of the health systems. But the 'mystique of markets' must not be allowed to deprive public hospitals of the sense of social utility and of the caring ethos which are essential requisites of a meaningful and effective public health system. 相似文献

目的:通过对医院平均住院日情况的简要分析,以探索缩短平均住院日的有效途径。方法:从统计室提取数据,与病案核对,计算相对指标。结果:我院的平均住院日呈下降趋势,但与卫生部颁布的标准还有差距,中医各科和康复科科别的平均住院日更长一些。结论:我院的平均住院日还有潜力可挖,术前住院日多数病种都较长,应在医疗质量和护理质量上狠下功夫,加强科室间的协作,降低平均住院日,减少无效住院日。 相似文献

Summary Serum digoxin and beta-methyldigoxin (BMD) were measured in 165 elderly patients (age >60 years) admitted to hospital, of whom 109 had been treated at home with digoxin and 56 with BMD.The mean BMD level was significantly lower than that of digoxin (1.1 vs. 1.4 ng/ml). Creatinine clearance and daily dose were the variables most strongly associated with digoxin level, and the prescribed dose and serum albumin were the best predictors of the BMD concentration. Compliance was assessed by a compliance index (CI), namely the ratio of the measured glycoside concentration, corrected for creatinine clearance, over the expected steady-state dose, calculated from a hospitalized reference group. Compliant individuals in both treatment groups, i.e. those with a CI > the median value, were characterized by a lower daily dose and dosage frequency.Toxicity, whether clinical or electrocardiographic, was present in 9% of the patients and was associated only with a significantly higher mean serum level of the drug. 相似文献
