Anaemia management protocols in the care of haemodialysis patients: examining patient outcomes.

AIMS AND OBJECTIVES: To determine whether the use of a nurse-driven protocol in the haemodialysis setting is as safe and effective as traditional physician-driven approaches to anaemia management. BACKGROUND: The role of haemodialysis nurses in renal anaemia management has evolved through the implementation of nurse-driven protocols, addressing the trend of exceeding haemoglobin targets and rising costs of erythropoietin-stimulating agents. DESIGN: Retrospective, non-equivalent case control group design. METHODS: The sample was from three haemodialysis units in a control group (n = 64) and three haemodialysis units in a protocol group (n = 43). The protocol group used a nurse-driven renal anaemia management protocol, while the control group used a traditional physician-driven approach to renal anaemia management. All retrospective data were obtained from a provincial renal database. Data were analysed using chi-square tests and t-tests. Patient outcomes examined were haemoglobin levels, transferrin saturation levels, erythropoietin-stimulating agents use and intravenous iron use. Cost comparisons were determined using average use of erythropoietin-stimulating agents and intravenous iron. RESULTS: Control and protocol groups reached haemoglobin target levels. In the protocol group, 75% reached transferrin saturation target levels in comparison with 25% of the control group. Use and costs for iron was higher in the control group, while use and costs for erythropoietin was higher in the protocol group. The higher usage of erythropoietin-stimulating agents was potentially related to comorbid conditions amongst the protocol group. CONCLUSIONS: A nurse-driven protocol approach to renal anaemia management was as effective as the physician-driven approach in reaching haemoglobin and transferrin saturation levels. Further examination of the use and dosing of erythropoietin-stimulating agents and intravenous iron, their impact on haemoglobin levels related to patient comorbidities and subsequent cost effectiveness of protocols is required. RELEVANCE TO CLINICAL PRACTICE: Using a nurse-driven protocol in practice supports the independent nursing role while contributing to safe patient outcomes.

Psychometric properties of the Oswestry disability index: Rasch analysis of responses in a work-disabled population.

BACKGROUND: The Oswestry disability index (ODI) is the most widely used measure of perceived disability for low back conditions. It has been adopted without adaptation in functional capacity evaluation (FCE). Rigorous testing of the ODI with modern psychometric methods, in this setting, is warranted. OBJECTIVE: To determine the psychometric properties of the ODI in FCE: unidimensionality; differential item functioning; item coverage and to identify poorly functioning items, allowing for improvement of these items and recalibration of the scale. METHODS: Rasch analysis, specifically Masters' partial credit model, was conducted on data. PARTICIPANTS: 133 work-disabled individuals presenting for FCE in northern British Columbia, Canada. RESULTS: All items had one poorly functioning option. Items were rescaled from six categories to five, improving the psychometric properties of the ODI as a unidimensional (disability due to back pain) scale. Item difficulty range is sufficient for a population with mild to severe disability. CONCLUSION: Although two of the ten ODI items functioned marginally unsatisfactorily in the unrevised state, the 5-option revised ODI appears superior. Use in clinical settings across a broad spectrum of disability levels could help establish its psychometric properties. Health professionals should be aware that the ODI may perform differently depending on client population.

Fibromyalgia: predicting openness to counselling referrals.

Fibromyalgia (FM) is a chronic pain condition that can negatively impact on all aspects of patients' lives. The purpose of this study was: first, to explore the biopsychosocial factors that may contribute to adjustment to FM symptoms; second, to investigate how referrals to counselling related to patients' ratings of their relationship with their physicians; and, last, to examine if self-reports of illness distress, emotional problems, and practical problems can predict who will be open to counselling referrals. For this cross-sectional study, data from 190 people were collected through an online survey. Statistical analysis revealed that emotional problems reported were the best predictor of variance in illness distress and contentment scores. Further, results indicated that referrals made in accord with patients' perceptions that they would benefit from counselling may have a positive influence on how patients rate their relationships with their physicians. Finally, self-reported scores of illness distress, number of emotional problems, and number of practical problems accurately predicted who would be open to counselling referrals in 67% of cases. Research results provide support for addressing emotional issues to facilitate adjustment to FM symptoms, and for use of psychosocial measures to determine when patients with FM will be open to counselling referrals.

Cognitive-behavioural treatment for women who binge eat.

PURPOSE: A dietitian-administered, shortened form of the Apple and Agras cognitive-behavioural therapy (CBT) method was evaluated in a group setting to determine its effect on improving obese women's self-esteem and reducing binge-eating behaviours, depression, and negative body image. METHODS: Participants were recruited through newspaper and radio advertisements. Respondents who met study selection criteria were randomly assigned to either a CBT group (n=13) or a delayed group (D-CBT) (n=9). The treatment was administered over six weekly sessions to the CBT group, and then twice weekly over three weeks to the D-CBT group. Two measures of bingeing behaviour (severity and frequency), three measures of mood (depression, body image, and self-esteem), and body weight were assessed. RESULTS: The intervention did not result in any changes in body weight. There were statistically significant and clinically important changes after treatment (p<0.05) for all five measures. Binge-eating severity and frequency decreased, depression decreased, body image improved, and self-esteem improved. All changes were greater in the six-week treatment group. CONCLUSIONS: The dietitian-administered, group setting CBT program is effective for reducing binge eating and improving emotional state in obese women.
