RESEARCH DESIGN AND METHODS A 3-year(More)
BACKGROUND Many nondonors are positive about blood donation and this motivates booking an appointment to donate. However, as their appointment approaches barriers to donating-such as anxiety-may become salient and deter attendance. Building on research of France and colleagues demonstrating the positive effect of enhanced preparation materials on donor(More)
BACKGROUND This research examined the effect of autologous serum eye drops (ASED) on ocular symptoms, visual-related functioning and quality of life for patients failing other therapies. METHODS Patients (N = 77) were asked to complete a survey prior to ASED use, and 2 and 12 months post-treatment. RESULTS Significant improvements in symptom frequency(More)
BACKGROUND Research demonstrates that anxiety elevates the risk of blood donors experiencing adverse events, which in turn deters the performance of repeat blood donations. Identifying donors suffering from heightened state anxiety is important to assess the impact of evidence-based interventions. This study analyzed the appropriateness of a shortened(More)
BACKGROUND AND OBJECTIVES Vein visualization technology (VVT) devices use near-infrared light to assist location of peripheral veins. The current study investigated the impact of VVT on donor experience and collection success for young blood donors at the Australian Red Cross Blood Service. MATERIALS AND METHODS The study in donors aged 18 to 30 years(More)
BACKGROUND Frequent blood donors are an important resource as they contribute many donations over their lifetime. The aim of this research was to develop a demographic profile of Australian frequent whole blood donors and to determine predictors of lapse within this group. STUDY DESIGN AND METHODS Routinely collected data were used to profile individuals(More)
BACKGROUND Vasovagal symptoms have implications for donor safety and retention. This study explored knowledge, attitudes and practices in donors experiencing a vasovagal reaction. MATERIALS AND METHODS Semi-structured interviews were conducted with donors (n = 30) who experienced a donation-related vasovagal reaction. RESULTS Donors were unaware of(More)
RESEARCH DESIGN AND METHODSdA 3-year longitudinal study was conducted using data from 142 individuals with type 1 diabetes, 8–19 years of age. Personality was assessed at baseline using the Five-Factor Personality Inventory for Children. Data relating to glycemic control (HbA1c) and frequency of blood glucose monitoring (based on meter memory) were(More)
BACKGROUND Each year, a large number of individuals in Australia are deferred from donating blood. A deferral may have a negative impact on donor satisfaction and subsequent word-of-mouth communication. The Australian Red Cross Blood Service (the Blood Service) is, therefore, investigating options for managing service interactions with deferred donors to(More)
