Changes of nursing organization in a surgical department: effects on work satisfaction and quality of care

• ? The aim of the study was to evaluate the effects of an organizational change programme in a surgical department in Sweden (the introduction of modular nursing) on the nursing staffs perception of job satisfaction and quality of care, and to identify factors which promote or hinder this organizational change.
• ? Planning and implementation of the change programme took about 1 year and comprised structural changes and staff training.
• ? Assessments of job satisfaction and quality of care were made immediately before, and 1 year after, implementation of the change programme. Data were collected from the staff of two wards.
• ? Virtually no statistically significant changes were found when looking at the department as a whole. However, considerable differences were noted between the two wards, particularly in the following areas: relationships with colleagues, identification and commitment, and perceived quality of care.
• ? The quality of the interpersonal relationships, and the leadership of the wards' head nurses, appeared to be crucial determinants of the outcome.

     

Essentials of psychotherapeutic intervention for cancer patients

Psychosocial treatments, including group, individual and family psychotherapies, are of proven efficacy, and deserve inclusion as standard components of biomedical treatment for cancer patients. Anxiety and depression are very common (and treatable) problems among cancer patients, most of whom can benefit from intervention. Psychotherapy, both group and individual, employs three fundamental approaches: emotional expression, social support, and cognitive symptom-management skills. Psychotherapy has been shown to be effective in improving quality of life. Results of studies of various psychotherapies include reduction in depression, anxiety, and pain, and improved coping skills, and, in some cases, there is evidence of extended survival times.Presented at the Symposium Psychotherapeutic Interventions in Cancer Patients, Flims, Switzerland, 12–14 January 1995

Quality of diabetes care in a university health center in Lebanon.

OBJECTIVE: To assess the quality of care provided to diabetic patients by family physicians in a university health clinic, using measures of glycemic and cardiovascular risk control as well as documentation of and adherence to World Health Organization (WHO) guidelines for diabetes primary care. DESIGN: Chart review of the previous year's medical notes for all identified diabetics in the practice over 2.5 years. RESULTS: Two-hundred and four diabetic patients were identified, with an estimated prevalence of 4.1%. The majority was type II diabetics, on oral hypoglycemic agents. Glycosylated hemoglobin was documented in 39.7% of patients, fasting plasma glucose in 99%, cholesterol in 93.1%, triglycerides in 91.2% and blood pressure in 85.8%; optimal control of these indicators was noted in 28.4%, 17.8%, 34%, 29.6% and 55.4% respectively. Fifty percent of the diabetics were referred for retinal checks. Physicians documented the presence of nephropathy in 46.8% and neuropathy in 59.6%; however, they documented patient instruction on foot care, diet, exercise and diabetes self-care poorly. CONCLUSION: There is a need for interventions to improve management and documentation in diabetes care in order to achieve early detection and prevention of complications. Developing a protocol for the clinic based on standard guidelines, and the use of flow sheets may be helpful in improving these intermediate indicators of quality of care.     

Efficacy of myofascial therapy and kinesitherapy in improving function in shoulder pathology with prolonged immobilization: A randomized,single-blind,controlled trial

BackgroundThe best physiotherapeutic approach in shoulder pathology that generates prolonged immobilization is still uncertain. Kinesitherapy remains the most widely used option. Myofascial therapy is a therapeutic approach in which the aim is to release fascial tension and regain mobility although its efficacy in shoulder pathology has not been sufficiently studied. This Prospective, single-blind randomized controlled trial in a university hospital setting aimed to compare the efficacy of myofascial therapy and kinesitherapy in improving function in shoulder pathology with prolonged immobilization.MethodsPatients were randomly assigned to a control group or to the intervention group.Both groups completed a therapeutic exercise program. Main Outcome Measures: The QuickDash questionnaire was the primary outcome, Pain Visual Analog Scale and the Range Of Motion of the shoulder were the secondary outcomes. The outcomes were evaluated at baseline (T0), at 4 (T2), 8 (T2), and 12 weeks (T3)Results44 participants were included. In the analysis of evolution over time, a significant improvement in functionality and range of motion measurements was observed in both groups (p < 0.05), although at 12 weeks only Myofasical Group achieved a clinically and statistically significant reduction in pain. Comparative analysis at 12 weeks revealed no statistically significant differences between the two therapies in the variables explored.ConclusionsBoth, myofascial therapy and kinesitherapy can improve function, mobility, and pain in patients with painful shoulder associated with prolonged immobilization, with no significant differences between therapies, although in the medium term only myofascial therapy achieves a clinically and statistically significant improvement in pain.Trial registrationTrial registration: ClinicalTrials.gov NCT04944446.     

Single-handed practices – their contribution to an undergraduate teaching network in the first year of the new curriculum

OBJECTIVES: The new curriculum at King's College School of Medicine and Dentistry, which commenced in September 1996, requires all medical undergraduates to have a general practice placement throughout the 5 years of their medical education. DESIGN: This paper discusses recruitment, training and support of teaching practices for the new curriculum, reviews the distribution of single-handed general practices in the network and, via a selection of monitoring and evaluation procedures, discusses the implications of a policy which is inclusive of single-handed practices. The findings relate to the experience of the first semester of the first year of the new curriculum. It also examines the contributions that single-handed practices have made to the teaching network and the kind of support needed, if single-handed practices are to continue to contribute to the King's teaching network. SETTING: King's College School of Medicine and Dentistry. SUBJECTS: Medical undergraduates. RESULTS: The findings of this paper revealed that over a third of general practice provision is via single-handed practices in South-east London. Within the undergraduate teaching network, 10% of practices are single-handed. Students are welcomed and receive a learning experience comparable to those students in larger practices. Attendance at training events has proved difficult for some of these tutors, but the extra input from the department, in order to address this deficit, has not been onerous. Indeed, single-handed practices have not been unique with regard to difficulties in attendance at training events. CONCLUSIONS: The study concludes that single-handed practices can make satisfactory provision for undergraduates in the new curriculum and there is no evidence from this study to suggest otherwise.     

Total purchasing, community and continuing care: lessons for future policy developments in the NHS

The introduction of total purchasing pilots (TPPs) into the National Health Service (NHS) gave general practitioners (GPs) significant new opportunities to take responsibility for the development of community and continuing care (CCC) services. Based on five case studies of TPPs involved in developing CCC this paper asks three questions: (1) to what extent were the TPP’s involvement in CCC informed by an awareness of CCC policy?; (2) were TPPs involved in joint commissioning to develop integrated purchasing or provision which was informed by population based needs assessment?; (3) were TPPs seeking to involve users, carers and voluntary agencies in their plans? The findings indicate that TPPs showed little awareness of national or local policy for CCC, although their project initiatives did address some of the policy issues (in particular a recognition of the need for joint working at the practice level). At the time of fieldwork, four of the case study TPPs had begun to investigate the potential for integrated purchasing, and three of them had relatively sophisticated models of both horizontally and vertically integrated provision of care. However, the TPPs developments were not based on systematic population based needs assessment. The paper concludes that there is potential for the primary care led groups proposed in the recent white papers in England, Scotland and Wales to improve integration of care both horizontally and vertically. However, they may need policy guidance and push to: encourage them to put CCC high on their agenda for action; to work with people with expertise in population based, prevention focused, needs assessment; and to find innovative ways to include users, carers and voluntary agencies. Incentives or levers (such as control over budgets) may be needed to promote joint working between staff in different agencies.     

Methods for evaluation of retinal microvascular abnormalities associated with hypertension/sclerosis in the Atherosclerosis Risk in Communities Study

OBJECTIVE: To develop protocols to photograph and evaluate retinal vascular abnormalities in the Atherosclerosis Risk in Communities (ARIC) Study; to test reproducibility of the grading system; and to explore the relationship of these microvascular changes with blood pressure. DESIGN: Population-based, cross-sectional study. PARTICIPANTS: Among 4 examination centers, 11,114 participants (48-73 years of age) at their third triennial examination, after excluding persons with diabetes from this analysis. METHODS: One eye of each participant was photographed by technicians with nonmydriatic fundus cameras. Reading center graders evaluated focal arteriolar narrowing, arteriovenous (AV) nicking, and retinopathy by examining slides on a light box and measured diameters of all vessels in a zone surrounding the optic disc on enhanced digitized images. To gauge generalized narrowing, vessel diameters were combined into central arteriolar and venular equivalents with formulas adjusting for branching, and the ratio of equivalents (A/V ratio) was calculated. MAIN OUTCOME MEASURES: Retinal vascular abnormalities, mean arteriolar blood pressure (MABP). RESULTS: Among 11,114 participants, photographs were obtained of 99%, with quality sufficient to perform retinal evaluations in 81%. In the 9040 subjects with usable photographs, A/V ratio (lower values indicate generalized arteriolar narrowing) ranged from 0.57 to 1.22 (median = 0.84, interquartile range = 0.10), focal arteriolar narrowing was found in 7%, AV nicking in 6%, and retinopathy in 4%. Because of attrition of subjects and limitation of methods, prevalence of abnormality was likely underestimated. Controlling for gender, race, age, and smoking status, these retinal changes were associated with higher blood pressure. For every 10-mmHg increase in MABP, A/V ratio decreased by 0.02 unit (P < 0.0001), focal arteriolar narrowing had an odds ratio (OR) of 2.00 (95% confidence interval [CI] = 1.87-2.14), AV nicking had an OR of 1.25 (95% CI = 1.16-1.34), and retinopathy had an OR of 1.25 (95% CI = 1.15-1.37). For any degree of generalized narrowing, individuals with focal narrowing had MABP approximately 8 mmHg higher than those without (P < 0.0001). Masked replicate assessment of a sample found the following reproducibility: for A/V ratio, correlation coefficient = 0.79 and median absolute difference = 0.03; for focal arteriolar narrowing, kappa = 0.45; for AV nicking, kappa = 0.61; and for retinopathy, kappa = 0.89. CONCLUSION: Protocols have been developed for nonmydriatic fundus photography and for evaluation of retinal vascular abnormalities. Several microvascular changes were significantly associated with higher blood pressure; follow-up will show whether these are predictive of later cerebrovascular or cardiovascular disease independently of other known risk factors.     

Diabetic retinopathy in a black population: the Barbados Eye Study.

OBJECTIVE: The distribution of diabetic retinopathy in black populations is largely unknown. The authors present retinopathy data from the predominately black participants of the Barbados Eye Study (BES). DESIGN AND PARTICIPANTS: Prevalence study of 4631 participants based on a random sample of the Barbados population 40 to 84 years of age (84% participation). MAIN OUTCOME MEASURES: Diabetes was defined as self-reported history of physician-diagnosed diabetes or glycosylated hemoglobin greater than 10% (>2 standard deviations above the population mean of persons without a diabetes history). Retinopathy was assessed by independent gradings of 30 degrees color stereo fundus photographs of the disc and macula. RESULTS: Diabetes was present in 19.4% of black (n = 4314), 15.2% of mixed (black and white; n = 184), and 7.5% of white/other (n = 133) self-reported racial groups. In the black/mixed population, regardless of diabetes status, the prevalence of retinopathy was 5.9%. In the 636 black and mixed participants with diabetes, the prevalence of retinopathy was 28.5%: 19.8% had minimum changes, 7.7% had moderate changes, and 0.9% had severe retinopathy. Clinically significant macular edema (CSME) was found in 8.6% of those with diabetes. CONCLUSIONS: In the population of African origin, approximately 1 in 17 persons had retinopathy. Among those with diabetes, 28.5% had retinopathy and 8.6% had CSME. These results highlight the clinical and public health relevance of diabetic retinopathy in the black population.     

A reevaluation of the functional organization and cytoarchitecture of the feline lateral posterior complex, with observations on adjoining cell groups

The organization of the cat's lateral posterior complex was reevaluated and its cytoarchitecture described. Analysis of visual representations within the complex confirmed that the pulvinar, lateral zone (LPL), and interjacent zone (LPi) correspond to separate representations of the visual field and established that the zones exhibit heterogeneous connections as a result of retinotopic interconnections with extrastriate areas which represent varying amounts of the visual field. A common system of visual representation extending through layers with differing anatomical connections was identified within zone LPL. The concept of an "isorepresentation cord" was introduced to describe these variable correspondences between sensory representations and connectional relationships. Isorepresentation cords are conceived as holding in common representation of a common locus on a sensory surface without functioning as a unit with respect to connections. Visual representations within the lateral posterior complex consist of many such cords arranged in orderly array. Zone LPm (medial) was also delineated more accurately on the basis of its connections with the ectosylvian visual area. Analysis of termination patterns which occupy boundary regions adjacent to and between the principal zones further established the existence of a collection of cell groups which form a thin, irregular shell investing the principal zones. The identification of these additional cell groups and the recognition of connectional heterogeneity within the principal zones of the complex made it possible to identify and describe the subtle cytoarchitectural differences which characterize the subdivisions of the lateral posterior complex and their boundaries with adjoining nuclear groups. The present findings are discussed with respect to the functions of the lateral posterior complex in interconnecting cortical visual and visuomotor areas, and with respect to the conceptual issues raised by variable correspondences between sensory representations and connectional relationships within thalamus.
