3261例老年患者医院感染分析及对策

目的　探讨老年人医院感染状况 ,以采取有效措施降低医院感染率。方法　对我院 3 2 61例老年住院患者进行回顾性调查分析。结果　 3 2 61例中 2 1 2例发生医院感染 ,感染率为 6 .5 % ,以下呼吸道感染为多 ,占 49.5 % ;其次为泌尿道感染 ,占 2 2 .0 % ;胃肠道感染占 1 6 .5 % ;皮肤感染占 6 .6 % ;其他感染占 5 .2 %。结论　老年患者抵抗力低下 ,不合理使用抗生素以及住院时间延长 ,是造成医院感染的主要因素 ,因此应加强老年患者的护理 ,提高其自身防御能力 ,严格加强感染管理制度及医院感染监测 ,合理使用抗生素 ,以有效地降低医院感染的发生。     

Langerhans cell sarcoma in a patient who underwent transplantation

Langerhans cell sarcoma is a rare, aggressive tumour that may metastasize to many organs, likely leading to death of the patient within 1 year. We present the first case described in the literature in a patient who underwent transplantation.     

An acute psychiatric rating scale for the clinical assessment of functionally disturbed inpatients

A 28-item behavioral rating scale, the Acute Psychiatric Rating Scale (APRS), was developed using factor-analytic methods for the assessment of functionally disturbed psychiatric inpatients. Fifty-eight staff rated 74 patients on the scale. Seven factorial dimensions were extracted comprising neuroticism, aggression, emotional withdrawal, cognitive impairment, schizophrenia, hypomania and self-injuriousness. The scale was evaluated in 4 different psychiatric inpatient units: two acute admission wards, an intensive care unit and a regional secure unit. Behavioral ratings on the scale were related to several patient demographic and treatment variables, including age, sex, marital status, legal status, length of admission and electroconvulsive therapy. The scale was found to possess a clear factorial structure, good interrater reliability and promising clinical validity for further research use in psychiatric inpatient settings.     

Intracranial actinomycosis in juvenile patients Case report and review of the literature

A case of actinomycotic brain infection in a juvenile patient is described. Cases of actinomycosis affecting the head and neck are rare, particularly in juvenile patients. In this case complete resolution of the infection was achieved by means of surgical treatment and prolonged antibiotic therapy. The authors emphasize the importance of a combined approach for treatment of this unusual brain infection and stress the difficulties involved in the diagnosis of this pathology.

高电压胸部摄影诊断和防护效果研究

作者以体模实验为基础。测定了不同管电压拍摄胸片时的病人剂量，考察了提高管电压对胶片影像质量的影响，结果表明，使用高电压拍摄胸片比使用低电压有利于降低病人剂量，在增加影像信息量，提高肋骨阴影区和纵膈区灶检出率方面更有较大优越性，此外，使用高电压技术不家利于延长Ｘ射线管的使用寿命。     

Are Continuity Clinic Patients Less Satisfied When the Resident Is Postcall?

Due to recent public debate and newly imposed resident work hour restrictions, we decided to investigate the relationship of resident call status to their ambulatory patients' satisfaction. Resident continuity clinic patients were asked to rate their level of satisfaction on a 10-point Likert-type scale. Using multiple regression approaches, these data were then assessed as a function of resident call status. We found that in 646 patient encounters, patient satisfaction scores were significantly less when the resident was postcall, 8.99 ± 1.8, than when not postcall, 9.31 ± 1.3. We herein discuss etiologies and implications of these findings for both patient care and medical education.     

The Use of Performance Improvement Methods to Enhance Emergency Department Patient Satisfaction in the United States: A Critical Review of the Literature and Suggestions for Future Research

Objectives: The authors reviewed the evidence on performance improvement methods for increasing emergency department (ED) patient satisfaction to provide evidence-based suggestions for clinical practice.
Methods: Data sources consisted of searches through MEDLINE, CINAHL, PSYCHINFO, Cochrane Library, and Emergency Medicine Abstracts and a manual search of references. Articles were included if they reported a performance improvement intervention targeting patient satisfaction in the ED setting. Articles on studies not conducted in the United States or that failed to provide enough details to allow critical evaluation of the study were excluded. Two authors used structured evaluation criteria to independently review each retained study.
Results: Nineteen articles met all selection criteria. Three studies found varying levels of support for multicomponent interventions, predominantly focused on implementation of clinical practice guidelines for specific presenting complaints and process redesign. Sixteen studies evaluated single-component interventions, with the following having at least one supportive study: using alternating patient assignment to provider teams rather than "zone"-based assignment, enhancing provider communication and customer service skills, incorporating information delivery interventions (e.g., pamphlets, video) that target patient expectations, using preformatted charts, and establishing ED-based observation units for specific conditions such as asthma and chest pain.
Conclusions: There is modest evidence supporting a range of performance improvement interventions for improving ED patient satisfaction. Further work is needed before specific, evidence-based recommendations can be made regarding which process changes are most effective. Recommendations are made for improving the quality of performance improvement efforts in the ED setting.
