Project description:BackgroundPressure ulcers affect approximately 10% of people in hospitals and older people are at highest risk. A correlation between inadequate nutritional intake and the development of pressure ulcers has been suggested by several studies, but the results have been inconsistent.ObjectivesTo evaluate the effects of enteral and parenteral nutrition on the prevention and treatment of pressure ulcers.Search methodsIn March 2014, for this first update, we searched The Cochrane Wounds Group Specialised Trials Register, the Cochrane Central register of Controlled Trials (The Cochrane Library), the Database of Abstracts of Reviews of Effects (DARE) (The Cochrane Library), the Health Technology Assessment Database (HTA) (The Cochrane Library), the Cochrane Methodology Register (The Cochrane Library), NHS Economic Evaluation Database (The Cochrane Library), Ovid Medline, Ovid Embase and EBSCO CINAHL. No date, language or publication status limits were applied.Selection criteriaRandomised controlled trials (RCTs) evaluating the effects of enteral or parenteral nutrition on the prevention and treatment of pressure ulcers, which measured the incidence of new ulcers, ulcer healing or changes in pressure ulcer severity. There were no restrictions on types of patient, setting, date, publication status or language.Data collection and analysisTwo review authors independently screened for inclusion, and disagreement was resolved by discussion. Two review authors independently extracted data and assessed quality using the Cochrane Collaboration tool for assessing risk of bias.Main resultsWe included 23 RCTs, many were small (between 9 and 4023 participants, median 88) and at high risk of bias.Eleven trials compared a combination of nutritional supplements, consisting of a minimum of energy and protein in different dosages, for the prevention of pressure ulcers. A meta-analysis of eight trials (6062 participants) that compared the effects of mixed nutritional supplements with standard hospital diet found no clear evidence of an effect of supplementation on pressure ulcer development (pooled RR 0.86; 95% CI 0.73 to 1.00; P value 0.05; I(2) = 13%, random effects). This outcome is at unclear or high risk of bias.Fourteen trials evaluated the effects of nutritional supplements on the healing of existing pressure ulcers: seven trials examined mixed nutritional supplements, three the effects of proteins, two trials examined zinc, and two studies examined ascorbic acid. The included trials were heterogeneous with regard to participants, interventions, comparisons and outcomes and meta-analysis was not appropriate. There was no clear evidence of an improvement in pressure ulcer healing from the nutritional supplements evaluated in any of these individual studies.Authors' conclusionsThere is currently no clear evidence of a benefit associated with nutritional interventions for either the prevention or treatment of pressure ulcers. Further trials of high methodological quality are necessary.

Project description:BACKGROUND:To optimize patient education, it is important to understand what healthcare professionals perceive to be ideal oncology medication education for patients to receive, and what they feel is their role and the role of others in its delivery. Education provided to patients is an important component of chemotherapy as it has been shown to benefit and positively impact patients who receive it. Educational interventions are often provided by multidisciplinary teams with the goal of improving patient care. However, few studies have explored the roles of healthcare professionals in delivering oncology medication education. OBJECTIVE:To explore the perspectives of healthcare professionals working in medical, gynaecological or hematological oncology to identify what they perceive to be optimal oncology medication education for patients. METHODS:Healthcare professionals (physicians, nurses and pharmacists) working in medical, gynaecological or hematological oncology at the Nova Scotia Health Authority, Central Zone were invited to participate in one-on-one, semi-structured interviews which were audio-recorded, transcribed and analyzed using thematic analysis. FINDINGS:Fifteen interviews, including five physicians, four nurses and six pharmacists were conducted from February to April 2018. Four major themes were identified: Delivery of oncology medication education, Facilitating the patient learning process, Multidisciplinary Approach and Understanding barriers to the healthcare professional in providing education. CONCLUSION:The identified themes uncovered novel ideas about how healthcare professionals felt oncology medication education could ideally be delivered to patients, and supported findings in the literature. Although participants discussed barriers to their ability to deliver optimal education, they also identified ways in which they can facilitate patient learning, for example, through the reinforcement of education. Participants recognized the importance of increasing collaboration and communication with the multidisciplinary team. This research will inform the design of any new models for oncology medication education at the Nova Scotia Health Authority, Central Zone and potentially other sites.
