Questionnaire data were managed using Microsoft Access® 2007 (Microsoft Corporation cheap cialis soft 20mg with visa, Redmond buy cialis soft 20 mg, WA purchase 20mg cialis soft mastercard, USA) 20mg cialis soft visa. The front end of the database was designed to simplify data entry and quality checking order 20 mg cialis soft with visa. Data were entered and quality checked (paper to digital) by a different member of the research team. This was completed for each form before follow-ups were posted. Digital data were regularly quality checked and an audit trail maintained. Following acceptance of the study final report to the funder, identifiable patient contact details (used for focus groups and interviews) were destroyed. At this point, practices were also asked to destroy any identifiable lists of patients approached for the study. All digital and paper data have been archived and managed in accordance with the NHS Ethics Committee, research and development and University of Stirling policies. Qualitative analysis Qualitative data analysis of focus groups and interviews followed the social constructivist version of 47 48, grounded theory, through which themes and subthemes were identified in the data. The social constructivist approach is an iterative process of review that allows for the incorporation of existing 47 48, knowledge and literature that can be drawn upon in the analysis process. NVivo 11 (QSR International, Melbourne, VIC, Australia) software was used to help facilitate the interviews. In an iterative process, all focus group transcripts and interview transcripts were reviewed by multiple team members to identify key themes in relation to our research questions. These themes were discussed and amended until a core set was agreed for use as a final coding frame, which was systematically applied to all data. The research team met throughout the analysis process to review the emerging themes and discuss areas of agreement or divergence until consensus was reached. Additional details on the qualitative data analysis are included in Chapters 3 and 6. The analysis was specifically intended to identify barriers to, and facilitators of, adoption/use, and was informed by the normalisation process theory (NPT). The NPT helps to explain how practices can become embedded in organisational and professional contexts. There are four generative mechanisms to help explain how change can be adopted and embedded: coherence (sense-making), cognitive participation, collective action and reflexive monitoring. The production and reproduction of a practice requires continuous investment by agents (in this case, PNs) over time. NPT mechanisms are constrained (or aided) by the operation of norms (notions of how beliefs, behaviours and actions should be accomplished) and conventions (how beliefs, behaviours and actions are practically accomplished). The NPT generative mechanisms and their constructs have provided a framework for analysis of the qualitative data, to help understand and think through implementation problems and to help identify techniques to solve them. This was drawn on at the start of the project, using the focus group data, to help shape improvements to the implementation process and the training materials. Researcher field notes and post-implementation interviews were then also subsequently used to identify further barriers to, and facilitators of, adoption. Analysis of audio-recorded consultations The analysis of audio-recordings consisted of classifying conversation segments according to whether they attended to physical health, mental well-being or social elements of care. The range of social circumstances attended to were also identified. The PCAM tool should encourage a conversation flow that attends to well-being and social circumstances throughout the consultations (not leaving it until the end, when time may be limited). The analysis, therefore, also included attention to when conversation segments appeared in the consultation. Attending to a mix of physical health, mental well-being and discussion of social circumstances through the consultation, and discussing a range of social circumstances, 14 NIHR Journals Library www. A list of codes by which to classify segments, based on the domains within the PCAM tool, was developed by the research team and consistently applied to all consultation recordings before and after nurse training in the use of the PCAM tool. Integration and synthesis of data sets Overall, the qualitative and quantitative analysis aimed to determine whether or not and how a future cluster trial should proceed. This included assessing whether or not recruitment, retention and data collection were achieved to a sufficient level, and whether or not the outcomes used were sensitive enough to detect change (at what level and for whom), as well as identifying any key methodological issues in converting from a feasibility or pilot trial to a full-scale trial, as established by Shanyinde et al. The ADePT decision aid is described and reported alongside the process evaluation in Chapter 7. This issue may be freely reproduced for the purposes of private research and study and extracts (or indeed, the full report) may be included in professional journals 15 provided that suitable acknowledgement is made and the reproduction is not associated with any form of advertising.
