MRSA model of learning and adaptation: a qualitative study among the general public

<p>Abstract</p> <p>Background</p> <p>More people in the US now die from Methicillin Resistant <it>Staphylococcus aureus </it>(MRSA) infections than from HIV/AIDS. Often acquired in healthcare facilities or during healthcare procedures, the extremely high incidence of MRSA infections and the dangerously low levels of literacy regarding antibiotic resistance in the general public are on a collision course. Traditional medical approaches to infection control and the conventional attitude healthcare practitioners adopt toward public education are no longer adequate to avoid this collision. This study helps us understand how people acquire and process new information and then adapt behaviours based on learning.</p> <p>Methods</p> <p>Using constructivist theory, semi-structured face-to-face and phone interviews were conducted to gather pertinent data. This allowed participants to tell their stories so their experiences could deepen our understanding of this crucial health issue. Interview transcripts were analysed using grounded theory and sensitizing concepts.</p> <p>Results</p> <p>Our findings were classified into two main categories, each of which in turn included three subthemes. First, in the category of <it>Learning</it>, we identified how individuals used their <it>Experiences with MRSA</it>, to answer the questions: <it>What was learned? </it>and, <it>How did learning occur? </it>The second category, <it>Adaptation </it>gave us insights into <it>Self-reliance, Reliance on others</it>, and <it>Reflections on the MRSA journey</it>.</p> <p>Conclusions</p> <p>This study underscores the critical importance of educational programs for patients, and improved continuing education for healthcare providers. Five specific results of this study can reduce the vacuum that currently exists between the knowledge and information available to healthcare professionals, and how that information is conveyed to the public. These points include: 1) a common model of MRSA learning and adaptation; 2) the self-directed nature of adult learning; 3) the focus on general MRSA information, care and prevention, and antibiotic resistance; 4) the interconnected nature of adaptation; and, 5) the need for a consistent step by step plan to deal with MRSA provided at the time of diagnosis.</p

Meta-analysis of adjuvant therapy following curative surgery for periampullary adenocarcinoma

Background Periampullary cancers are uncommon malignancies, often amenable to surgery. Several studies have suggested a role for adjuvant chemotherapy and chemoradiotherapy in improving survival of patients with periampullary cancers, with variable results. The aim of this meta-analysis was to determine the survival benefit of adjuvant therapy for periampullary cancers. Methods A systematic review was undertaken of literature published between 1 January 2000 and 31 December 2015 to elicit and analyse the pooled overall survival associated with the use of either adjuvant chemotherapy or chemoradiotherapy versus observation in the treatment of surgically resected periampullary cancer. Included articles were also screened for information regarding stage, prognostic factors and toxicity-related events. Results A total of 704 titles were screened, of which 93 full-text articles were retrieved. Fourteen full-text articles were included in the study, six of which were RCTs. A total of 1671 patients (904 in the control group and 767 who received adjuvant therapy) were included. The median 5-year overall survival rate was 37·5 per cent in the control group, compared with 40·0 per cent in the adjuvant group (hazard ratio 1·08, 95 per cent c.i. 0·91 to 1·28; P = 0·067). In 32·2 per cent of patients who had adjuvant therapy, one or more WHO grade 3 or 4 toxicity-related events were noted. Advanced T category was associated worse survival (regression coefficient −0·14, P = 0·040), whereas nodal status and grade of differentiation were not. Conclusion This systematic review found no associated survival benefit for adjuvant chemotherapy or chemoradiotherapy in the treatment of periampullary cancer
