However generic actos 15mg with mastercard managing diabetes blood sugar levels, the participants described the value in knowing information about the patient that might influence the care they provided to the patient cheap 30mg actos with mastercard blood sugar keeps going up, by being sensitive to the context of that individual and their challenges. The nurse participants perceived this to be beneficial for both the patient and the nurse, in relation to both the quality of the relationship and the quality of the care provided. Signposting As part of its participation in the project, each practice was given a locally relevant collection of resources to which they could direct patients in response to any concerns raised by the various PCAM topic areas. The resource pack provided by the research team was very well received by the nurse participants. Some of the participants knew their local agencies and resources well, and did not find that the pack offered new information, although the convenience of it being provided in a folder was appreciated. Some nurse participants had not known of the local resources provided in the folder and were very pleased to have that information made available to them. Some participants expressed concern that they were unlikely to have the time and capacity to update the information following the conclusion of the project. Nurse interview, participant 745 58 NIHR Journals Library www. Nurse interview, participant 41 Participants also talked about copying and sharing the resource pack across the practice, and with colleagues who were not part of the research, as it was found to be of benefit for other staff to also be able to access: It was very easy. We were just saying that it would be good to copy it and let other staff in the practice use it too. Nurse interview, participant 178 Overall, there was a sense that the nurses found the resource pack very useful and had been active in signposting patients to various supports. This seemed to be accompanied by an approach of helping patients to access support for themselves and to address what their own priorities were, rather than focusing on fixing clinical issues: For patients to take the responsibility of looking after themselves with support from us and the better we can support them then hopefully the easier they will find it to take on the responsibility for their own health. Nurse interview, participant 745 Intended future use of the Patient Centred Assessment Method Participants were asked to reflect on their intentions around integrating PCAM-based consultations into their ongoing practice, beyond the course of the research project.

STUDY D: NURSE AND PATIENT PERCEPTIONS OF USING THE PATIENT CENTRED ASSESSMENT METHOD No participant in their feedback stated that they were opposed to using the PCAM in the future or made any comments indicating that they would be avoiding using the PCAM. Long-term adoption of the PCAM appears likely for some of the nurse participants in this research, beyond the research project itself. Conclusion The PCAM implementation did not have a negative or obstructive impact on the consultation. There was some indication that a small number of patients may have been aware of more discussion about their lives and their broader concerns. The PCAM training was acceptable, but required a multifaceted approach to training that integrated key information/knowledge, role playing and opportunities to apply the training to real consultations. Future training delivery will require the incorporation of these different aspects, and in a way that is flexible with nurse availability and workload. Overall, it appears that the PCAM was fairly easily integrated into consultation, although some participants reflected that the process of integration took some time and support, which will need to be taken into account in future training and support. The nurse participants perceived this to be beneficial for both the patient and the nurse, in relation to both the quality of the relationship and the quality of the care provided. Resource packs were seen as integral to using the PCAM, and practices engaged with these resources, often to the extent of taking ownership of their continuing development. However, for some practices, this could be seen as a future problem (how to keep these resources up to date) that could have an impact on their use of the PCAM. Long-term adoption of the PCAM was seen as feasible and possible by some nurses, which indicates overall potential for the acceptability and feasibility of the PCAM for use in primary care nurse-led consultations. The data used for the overall evaluation comprised: l contributions from study A focus groups with practices and patients on the acceptability and feasibility of the use of the PCAM, and any early reflections on barriers to using the PCAM in PN consultations l researcher field notes of meetings and discussions with staff l any comments to the research team or reported by practice staff from patients during implementation l data from study D, the final interviews with practice staff and patients l data from open-ended questions on staff and patient questionnaires collected as part of study B. The methods for studies A, B and D have been reported elsewhere. The collection of study field notes was seen as a fundamental part of the process evaluation and was ongoing throughout the study. Each study researcher kept their own logbook of visits and contacts with practices and any reported incidents/ problems, actions or comments associated with the study. The two researchers (EC and PA) had the most contact with practices, and each had more of a relationship with particular practices, thereby building rapport with practice staff and facilitating catch-up telephone or e-mail conversations between practice visits.
