A repeated measures design was used to evaluate a 12 month on-site counsellor internship programme aimed at training staff to support the recovery needs of people with co-occurring substance use and mental health disorders. Fifty-four interns completed measures of recovery knowledge, attitudes, confidence/competence, as well as identifying significant learning events. Statistically significant improvements were found in terms of attitudes and confidence/competence, and only one recovery knowledge factor, ‘roles of self-definition and peers in recovery’. Recovery knowledge at the end of the internship was positively associated with increases in interns’ confidence/competence but was not associated with changes in the interns’ attitudes. The mentoring, training/feedback and observational elements of the internship programme were highly valued by interns. Competency based learning events were most frequently identified as significant. Strategies to increase self-directed and interpersonally focused learning, and specific personal recovery knowledge in training are discussed. 相似文献

Aims and objectives
This study aimed to determine the influences of gender, BMI and observed body shape on subcutaneous fat and muscle thicknesses, and theoretical injection outcome, at the ventrogluteal and dorsogluteal intramuscular injection sites.Background
Debate continues as to whether the dorsogluteal or ventrogluteal injection site is more reliable for a successful intramuscular injection outcome. Subcutaneous fat and muscle thicknesses at the injection site are direct determinants of intramuscular injection outcome. BMI and observed body shape influence gluteal subcutaneous fat and muscle thicknesses, and therefore injection outcome, with potentially distinct effects at the ventrogluteal and dorsogluteal sites.Design
This was a cross‐sectional study.Methods
Demographic data were collected, and subcutaneous fat and muscle thicknesses were quantified bilaterally at the dorsogluteal and ventrogluteal injection sites using ultrasound, for 145 participants (57% female).Results
Subcutaneous fat and muscle were significantly thicker at the dorsogluteal than the ventrogluteal site, and 75% and 86% of participants would receive a successful intramuscular injection at these sites, respectively. There were significant effects of gender, BMI and observed body shape on subcutaneous fat thickness and theoretical injection outcome at both sites. Females, obese individuals and endomorph individuals had thicker subcutaneous fat and were more likely to have a subcutaneous injection outcome.Conclusions
Gender, BMI and observed body shape could be used to guide site and needle length selection when administering gluteal intramuscular injections to increase the likelihood of a successful intramuscular injection outcome.Relevance to clinical practice
Both gluteal injection sites should be avoided in obese individuals and endomorph individuals. An intramuscular injection will be successful: using a 32‐mm needle at the ventrogluteal site for all males and normal‐weight females and using a 38‐mm needle for all females at the ventrogluteal site, and for all males and at least 98% of females at the dorsogluteal site. 相似文献78.

This paper reports on a funded project that explored the perceptions and experiences of mentors regarding student nurse support in practice. The study employed a mixed‐method approach, using questionnaires and focus groups with mentors from one acute Trust and one community Trust. The findings highlighted the multifaceted nature of student learning in practice, with mentors reporting that clinical skills, adjustment to the placement and integrating into the team were the aspects students needed most support with. Mentors were aware of their roles and responsibilities in supporting students and recognized the importance of their own personal attributes. The participants reported a number of challenges, particularly time, competing demands and paperwork, and suggested that a team approach and support groups could help to overcome these. The support for students provided by peers and health‐care assistants was recognized, as was the need to ensure that students are prepared to take responsibility for their learning. 相似文献
