Establishing good practices in continuing care: a descriptive study of community nursing services for people with HIV infection

This paper presents findings from a 2-year study of community nursing services for people affected by HIV infection in six health authorities in England The research, commissioned by the Department of Health, England, aimed to identify the main bridges and barriers to effective home nursing care, focusing on discharge co-ordination, district nursing and multi-agency collaboration Using a triangulated, case study approach, the main methods of data collection included non-participant observation, case note analysis, semi-structured staff interviews, a postal questionnaire of district nurses and a series of focus groups with service users Study sites included three cities and surrounding districts in the north west, north and south east of England Findings suggest there is considerable room for improvement in discharge planning and that good practice is not the preserve of specialist units District nurses are shown to be willing providers of the majority of home nursing care to this client group, but there is a need for more focused training, greater use of care co-ordinators and more emotional and managerial support     

The theory/practice 'gap': taking issue with the issue

Theory/practice issues have a long-standing history in nurse education, and are a chronic source of controversy to which there is no easy or perfect solution We have argued that it is the tension between theory and practice and research which can be usefully exploited in teaching and research Students need to be introduced to the debates surrounding the genesis and generation of nursing knowledge They need to gain an appreciation of what counts as nursing knowledge at different points in time and the politics which drive the legitimation of nursing theory and practice Such an approach has much to offer in helping students deal with reality shock and make sense of their experience as they confront the ambiguities, uncertainties and contradictions that characterize the stock-in-trade of professional life     

Beneficial effects of fluvastatin on progressive renal allograft dysfunction

To assess the time-dependent changes in renal function in relation to antioxidant and lipid-lowering effects of fluvastatin in hyperlipidemic renal transplant recipients, 20 patients were treated with fluvastatin 40 mg/d for 12 months, after failure of a dietary program. Plasma malondialdehyde (MDA) levels and lipid profiles were evaluated in relation to serum creatinine and calculated creatinine clearances 18 months before and during the fluvastatin treatment. Mean baseline lipid values were: total cholesterol 318 mg/dL, triglycerides 212 mg/dL, LDL cholesterol 219 mg/dL, HDL cholesterol 58 mg/dL, apolipoprotein A 176 mg/dL, and apolipoprotein B 145 mg/dL. During 12 months of treatment, fluvastatin produced consistent and significant reductions in total and LDL cholesterol (-18.4% and -24.1%), triglycerides (-17.7%), and apolipoprotein B (-22.7%) as well as an increase in HDL cholesterol (12.3%) and apolipoprotein A (9.2%). Plasma MDA levels decreased by 41.8% (from 3.5 +/- 0.3 to 1.8 +/- 0.1 nmol/mL, P =.00002). Creatinine clearance, which had been declining at a rate of 0.32 mL/min/month during the previous 18 months before treatment, progressively improved during treatment, giving a positive slope of the creatinine clearance, which increased by 0.35 mL/min/month, (P =.016; 53.3 +/- 4.2 mL/min vs 49.8 +/- 4.1 mL/min pretreatment). Multiple linear regression analysis revealed that MDA was the parameter most closely associated with the variability in creatinine clearance. In conclusion, renal transplant patients with lipid abnormalities display renoprotective activity of fluvastatin, possibly due to its lipid-lowering and antioxidant effects.     

Students'' expectations of postregistration degree programmes

The needs of postregistration students pursuing degree-linked clinical courses have received little attention and there are few insights concerning their aspirations when they enrol on such courses. Thus the aim of this study was to explore postregistration students' perceptions of the specific needs of their patient/client group and to examine how they envisaged the course on which they had just enrolled might help them to meet these needs in addition to their own requirements for professional and personal development. Data were collected by group interview from 62 students enrolling on eight different postregistration courses, all employed in an acute hospital trust. The results were analysed inductively. They indicated that students had internalized the state of the healthcare market and were keenly aware of the need to fulfil the expectations of employers and the public, while fulfilling their own needs for education and pursuing their own professional and career trajectories. They appeared ambitious and yet appeared to demonstrate empathy for patients and their families and felt a tremendous desire to provide care of a high quality through the optimal development of technical expertise. Students' emphasis on the importance of keeping abreast of technological developments should not be lightly dismissed considering its prominent position within the acute areas where they were employed, especially as it did not replace their desire to promote the caring aspects of their work.

Osteosarcoma: use of MR imaging and MR spectroscopy in clinical decision making

Magnetic resonance (MR) imaging was performed on 14 patients with histologically proved osteosarcoma (mean age, 14.4 years). There was excellent correlation of intramedullary tumor extent as determined with MR imaging and pathologic examination (r = 99%). This was facilitated by the presence of a chemical shift artifact at the tumor-marrow interface on the T1-weighted images. The correlation between CT and pathologic findings was not as good (r = 84%). In a single patient, however, a 10-cm length of sclerotic bone was incorrectly interpreted as being tumor. If this case is excluded, the correlation between CT and pathologic findings improves significantly (r = 96%). T2-weighted images were optimal in demonstrating soft-tissue bulk and breach of the epiphysis or cortex. Vascular involvement was also readily defined. The T2 value of the tumor soft-tissue component decreased in patients who were deemed to have responded well to therapy. Two patients with very high T2 values after chemotherapy developed wide-spread metastatic disease and died. Phosphorus-31 MR spectroscopy of five patients with osteosarcoma showed elevated levels of phosphomonoesters (PMEs), inorganic phosphate (Pi), and phosphodiesters (PDEs). PME and PDE peak areas decreased in three patients after chemotherapy, while Pi peak areas increased.     

Primary Ewing sarcoma: follow-up with Ga-67 scintigraphy

While avid accumulation of gallium-67 citrate and technetium-99m methylene diphosphonate (MDP) occurs initially in most cases of primary Ewing sarcoma, uptake after therapy is less well defined. Thirty patients with Ewing sarcoma who underwent Ga-67 and bone scintigraphy at diagnosis, at completion of therapy, and at relapse from 1978 to 1988 were evaluated. All 30 patients showed less primary site Ga-67 activity following therapy. Twenty-three of 28 patients who underwent corresponding bone scintigraphy showed less uptake, but residual activity was usually more intense than with Ga-67. Avid reaccumulation of Ga-67 occurred in four of five patients with primary site relapse, while patients who underwent bone scintigraphy showed less change. It was concluded that a greater decrease in Ga-67 than in Tc-99m MDP uptake often occurs in patients successfully treated for primary Ewing sarcoma. Information obtained at Ga-67 scintigraphy is most likely to be helpful if results of bone scintigraphy remain abnormal or if occult relapse is suspected.     

Nurses'' opinions of the introduction of computer-assisted learning for use in patient education

Computers have only recently begun to find a place in the everyday work of health care staff. The use of computer-assisted learning (CAL) in patient education is in its infancy. However, the medium appears to offer several advantages to patients. The successful integration of the medium into clinical practice requires the acceptance and support of staff members. Little research exists to date which examines staff responses to the introduction of CAL into their workplace. This small study (n = 14) aims to explore the reactions of staff to the introduction of an experimental CAL package for use in the education of renal patients on continuous ambulatory peritoneal dialysis (CAPD). The opinions of staff members to CAL are probed and their views ascertained regarding the usefulness of CAL to both staff and patients. Results suggest that, despite their initial reservations about CAL, staff were generally positive about the medium.
