An exploration of the role of the nurses'' uniform through a period of non-uniform wear on an acute medical ward

The nursing staff on an acute medical hospital ward elected to wear their own clothes to work for a period of 2 months. The trial was evaluated using a variety of research methods and it raised a number of issues about the role of uniform, about patients' perceptions of nurses and nurses' perceptions of their role. The study has led to questions being raised about the assumptions that are made if uniform is worn and the appropriateness of a uniform dress.     

Kinetic changes in experimental colonic urinary diversion

An experimental model of colonic urinary diversion was performed on male Wistar rats to see if faeces, urine or a faeces and urine mixture produces tumours. Cell kinetic techniques, including the crypt cell production rate, and cellular DNA measurement were used to examine the effect of urine and of faeces on the colonic mucosa. Urinary diversion into the colon significantly increased colonic crypt activity. Tumours were found at the anastomosis when urine and faeces were mixed at 4 months, and at 6 months with urine alone.     

Management review of nursing systems

This paper describes the systems of nursing operating at a major cancer centre in the United Kingdom. The review was undertaken over a period of 8 weeks and 11 wards were included. The systems being implemented were primary nursing, team nursing and patient allocation. Methods of enquiry included questionnaires, non-participative observation and interviews. The results of the review found the nursing systems to be at various stages of implementation, and that in reality, not all wards were operating the system they said they were. A pragmatic mixture of team nursing and primary nursing as described by Hegyvary (1982) was being practised on some of the wards. The report makes recommendations for change, and concludes by discussing the future implications for cancer nursing at the centre.     

Effect of exogenous progesterone administration on the morphology of normally developing endometrium in the pre-implantation period

The effects on endometrial morphology of a single, intramuscular dose of 100 mg of progesterone administered in the early luteal phase, between days LH + 1 and LH + 6, were studied in a group (n = 8) of normal, fertile subjects by morphometric techniques and transmission electron microscopy. While the dose of progesterone administered consistently resulted in an increase of salivary progesterone concentration to above the upper limit of the reference range, no significant effect on endometrial development was observed; in particular, endometrial development was not advanced.     

Analysis of trauma intubations

The timing of trauma patient intubation is dependent on clinical presentation and clinician judgment. We sought to correlate the timing of intubation with the presenting of physiologic parameters and clinical outcome to identify potential quality assurance audit filters. Patients (n = 82) were grouped by timing of intubation: PREHOSPITAL, paramedic intubation; IMMEDIATE, within 10 minutes of arrival; DELAYED, beyond 10 minutes but within 2 hours of arrival; and NONURGENT, beyond 2 hours or at the time of surgery. While mean revised trauma scores and Glasgow Coma Scale (GCS) scores differed for the groups, the mean length of hospital stay and the incidence of aspiration pneumonia were not significantly different. In the DELAYED group, 80% of those who developed aspiration pneumonia had a GCS < or = 13. Patients in the NONURGENT group were older and commonly presented with tachypnea. The survival rate for the NONURGENT group was lower than predicted by the TRISS method (P = .004). A GCS < or = 13 and age greater than 50 years with presenting respiratory rates of more than 25 breaths/min represent potential trauma intubation audit filters.     

界定需要急诊入院的高危人群单纯依据既往的入院率会造成误导

预测哪些人可能因急性发病而需要急诊入院，已成为英国国家医疗卫生服务体系（NHS）的一个重要话题。卫生部门将那些患有复杂的慢性疾病，经常不定期地去二级医疗机构就医的人们视为高危人群。确定这些人之后，社区护理员或其他卫生人员将通过“个案管理”的方法照顾他们。“个案管理”此前被定义为“对疾病尚未控制或所需费用昂贵的患者进行加强医疗计划”。社区护理人员可来自任何护理部门，但一般认为社区护士更能胜任这一角色。此方法能够减少可避免的急诊入院患者数量，并有助于实现到2008年3月减少5％急诊住院床位日的公共医疗服务目标。但是，如何才能界定需要急诊入院的高危人群呢？     

RESULTS OF EXTERNAL BEAM RADIOTHERAPY IN 448 PATIENTS WITH CLINICALLY LOCALIZED ADENOCARCINOMA OF THE PROSTATE

The results of external beam radiotherapy for clinically localized adenocarcinorna of the prostate in 448 patients treated in the period 1980–90 were reviewed. The average follow up was 4.9 years. The patients were aged 44–87 years (median 69 years) and all had histopathological evidence of adenocarcinoma by needle biopsy or transurethral resection of prostate. The histopathological grading was: 127 G₁; 154 G₂; 127 G₃; 12 G₄; 28 G_x. Clinical staging according to TNM (American Urological Association) was: 29 T₀ (A2); 4 T₁ (B1); 173 T₂ (B2); 176 T₃ (C1); 63 T₄ (C2); 3 T_x. Routine surgical pelvic lymph node staging was not performed but patients had radiological (computerized tomography scan or lymphogram) nodal staging: 350 N₀; 22 N₁; 12 N₂; 64 N_x. High energy linear accelerator external beam radiotherapy was given by multiple fields to total doses of 50–70 Gy (median 60 Gy). The majority of patients (307, 69%) was treated by a uniform policy under the care of one radiation oncologist (HM). The rates of local and distant failure at 5 years were 10% (s.e. = 2%) and 42% (s.e. = 3%), respectively. The late complication rate at 5 years was 25% (s.e. = 2%), comprising mild 16%, moderate 7% and severe 1.3%. The 5 year overall survival rate was 64% (s.e. = 2%) and the cancer-specific survival rate was 74% (s.e. = 3%). Both histological grade and clinical stage were strongly predictive of overall survival and distant failure. Only histological grade was predictive of local failure. Treatment with external beam radiotherapy for this common cancer resulted in survival and disease control rates that compare favourably with other published radiotherapy series and has been accompanied by acceptably low morbidity.
