This is especially so when an intervention aims to change practitioner behaviour/ outcomes as well as patient behaviour or outcomes generic calan 120 mg without prescription. However cheap calan 80mg with mastercard, after the first training session in one practice, it became apparent that training delivery would have to be tailored to suit individual practice needs. The content of the training was also adapted in response to early nurse feedback in order to maximise learning in the limited time available. The essential element of learning why it is important to conduct a biopsychosocial assessment, and how to use the PCAM tool to facilitate this, was still delivered to all PNs. There was still some attempt in our adaptations to ensure that nurses had received equivalent training intensity and follow-up support.

APPENDIX 1 When the PCAM tool is being used in LTC annual reviews, the delivery of this is very much dependent on the individual circumstances of the patient, and also with individual practice procedures for patient follow-up if required. Item 10: modifications – if the intervention was modified during the course of the study, describe the changes (what, why, when and how) It was planned that the PCAM tool used in the study should be open to adaptation in response to management and steering group partners, and to focus group and feasibility RCT findings. However, it was important that it did not change during the feasibility RCT and that it remained congruent with the US version. The following changes were all made before the feasibility RCT: l For clarity, abbreviations were expanded. This was consistent with the rest of the document and International Classification of Functioning, Disability and Health (ICF) wording. The modification to the training intervention and delivery has been reported under Item 3 above. The resource packs were designed to be an evolving resource and to encourage local ownership of the resource for ongoing use. Some practices added new resources to these packs or deleted services if they no longer operated. Nurses were then allowed to discuss any queries or issues with the researcher/trainer before using the PCAM tool in phase 2 of the study. Intervention fidelity was studied using a sample of recorded nurse-led annual reviews before and after training in the use of the PCAM tool was delivered. This was to assess how nurses conducted their annual reviews before and after PCAM introduction, specifically, whether or not nurses already conducted a biopsychosocial assessment in the annual review of patients with LTCs and, if so, what domains (as specified in the PCAM) did they cover and whether or not the PCAM made any difference to their delivery of a biopsychosocial assessment, and what domains of the PCAM tool they were covering in this assessment. Nurses approached patients to get consent to record the consultation for up to five patients before and five patients after the introduction of the PCAM tool. Recordings were then transcribed and analysed, by Patricia Aitchison and Eileen Calveley, based on a predefined template that sought to categorise interactions based on the PCAM domains and to note when these occurred within the consultation. The PCAM intervention was used by all PCAM-trained nurses and the analysis of the small number of recorded consultations indicates that nurses are including more domains of the PCAM tool in their annual assessments than they did prior to the introduction of the PCAM tool. The resource packs were found to be helpful by PNs and other members of the primary care team, but there was concern about who would keep this resource up to date beyond the study.

PCAM may not be copied or shared with any third party without inclusion of the copyright declaration. There are no licence costs for the use of PCAM and the developers are committed to PCAM being freely available to use. In order to do this: l nurses were asked to provide anonymous case studies l evidence was presented for each of the LTCs under consideration l nurses were ask to share and reflect on the evidence and their case study patients. Each case was discussed in terms of suitability and application of the PCAM tool l nurses were provided with some examples as to how the PCAM tool items may be introduced and discussed, and then invited to role play l each nurse was encouraged to practise the PCAM tool with around 10 patients. For the sake of the study, these did not always have to be LTC patients. In order to build experience and confidence, it was suggested that they begin with just a few domains. They should reflect on each experience and discuss with colleagues as required l a researcher was attached to the practice and provided support in one additional face-to-face session, online and by telephone. In addition, the nursing team were provided with: l hard copies of the presentation slides l a copy of Making it Easy, A Health Literacy Plan for Scotland64 l a copy of Good Mental Health For All. However, after the first session, it became apparent that nurses: l would be unlikely to be able to dedicate a full unbroken half-day l may benefit from focusing the evidence further upon their own experience.
