Visual functioning and health-related quality of life in diabetic patients about to undergo anti-vascular endothelial growth factor treatment for sight-threatening macular edema

Purpose To examine patient-reported outcome (PRO) in a selected group of Swedish patients about to receive anti-vascular endothelial growth factor (VEGF) treatment for diabetic macular edema (DME). Material and methods In this cross-sectional study, 59 patients with diabetes mellitus, who regularly visited the outpatient eye-clinics, were included. Sociodemographic and clinical data were collected and the patients completed PRO measures before starting anti-VEGF treatment. PRO measures assessed eye-specific outcomes (NEI-VFQ-25) and generic health-related quality of life (SF-36). Results The participants consisted of 30 men and 29 women (mean age, 68.5 years); 54 (92 %) patients had type 2 diabetes; Five (9%) patients had moderate or severe visual impairment; 28 (47 %) were classified as having mild visual impairment. Some of the patients reported overall problems in their daily lives, such as with social relationships, as well as problems with impaired sight as a result of reduced distance vision. Conclusions Further studies are needed to investigate PRO factors related to low perceived general health in this patient population. It is important to increase our understanding of such underlying mechanisms to promote improvements in the quality of patient care.

‘Teaching corner’: Management of Diabetic Retinopathy

Sub-Saharan Africa faces an epidemic of diabetes. Visual loss from diabetic retinopathy (DR) is both preventable and treatable. This article reviews the epidemiology and clinical features of DR and current evidencebased interventions in three areas: primary prevention of retinopathy by optimum medical management, early detection of pre-symptomatic disease and management of established retinopathy to prevent or mitigate visual loss. There are significant challenges to DR care in resource poor environments. Appropriate provision of effective interventions by health services can reduce social and economic costs associated with patient care.

Chronic disease self-management in Aboriginal communities : towards a sustainable program of care in rural communities

The Chronic Disease Self-Management (CDSM) strategy for Aboriginal patients on Eyre Peninsula, South Australia, was designed to develop and trial new program tools and processes for goal setting, behaviour change and self-management for Aboriginal people with diabetes. The project was established as a one-year demonstration project to test and trial a range of CDSM processes and procedures within Aboriginal communities and not as a formal research project. Over a one-year period, 60 Aboriginal people with type-2 diabetes in two remote regional centres participated in the pilot program. This represents around 25% of the known Aboriginal diabetic population in these sites. The project included training for four Aboriginal Health Workers in goal setting and self-management strategies in preparation for them to run the program. Patients completed a Diabetes Assessment Tool, a Quality of Life Questionnaire (SF12), the Work and Social Adjustment Scale (WASAS) at 0, 6 and 12 months. The evaluation tools were assessed and revised by consumers and health professionals during the trial to determine the most functional and acceptable processes for Aboriginal patients. Some limited biomedical data were also recorded although this was not the principal purpose of the project. Initial results from the COAG coordinated care trial in Eyre suggest that goal setting and monitoring processes, when modified to be culturally inclusive of Aboriginal people, can be effective strategies for improving self-management skills and health-related behaviours of patients with chronic illness. The CDSM pilot study in Aboriginal communities has led to further refinement of the tools and processes used in chronic illness self-management programs for Aboriginal people and to greater acceptance of these processes in the communities involved. Participation in a diabetes self-management program run by Aboriginal Health Workers assists patients to identify and understand their health problems and develop condition management goals and patient-centred solutions that can lead to improved health and wellbeing for participants. While the development of self-management tools and strategies led to some early indications of improvements in patient participation and resultant health outcomes, the pilot program and the refinement of new assessment tools used to assist this process has been the significant outcome of the project. The CDSM process described here is a valuable strategy for educating and supporting people with chronic conditions and in gaining their participation in programs designed to improve the way they manage their illness. Such work, and the subsequent health outcome research planned for rural regions, will contribute to the development of more comprehensive CDSM programs for Aboriginal communities generally.

Smoothing a Discrete Hazard Function for the Number of Patients Colonized with Methicillin-Resistance Staphylococcus Aureus in an Intensive Care Unit

A new method for estimating the time to colonization of Methicillin-resistant Staphylococcus Aureus (MRSA) patients is developed in this paper. The time to colonization of MRSA is modelled using a Bayesian smoothing approach for the hazard function. There are two prior models discussed in this paper: the first difference prior and the second difference prior. The second difference prior model gives smoother estimates of the hazard functions and, when applied to data from an intensive care unit (ICU), clearly shows increasing hazard up to day 13, then a decreasing hazard. The results clearly demonstrate that the hazard is not constant and provide a useful quantification of the effect of length of stay on the risk of MRSA colonization which provides useful insight.
