The research also aimed to test the feasibility of running a cluster randomised trial in primary care 5 ml fml forte overnight delivery. The difficulty in recruiting primary care practices in Scotland fml forte 5 ml otc, and the number of practices approached to obtain the six that agreed to take part order 5 ml fml forte with amex, led to the conclusion that it would not be feasible to run a large-scale cluster randomised trial in the current climate of primary care in Scotland purchase fml forte 5 ml overnight delivery. If practice interest and support could be generated, it would be possible to engage nurses in such a trial, although they would also require more support in any data collection activity. The inevitable crises that can happen in primary care, coupled with the small numbers of staff involved (most practices have only one or two nurses), mean that it can be difficult even for the most motivated of practices to guarantee participation when staff shortages (from illness or other reasons) occur. There are also many times when practice priorities have to come before research needs, such as annual mass vaccination programmes or clearing backlogs of annual check-ups.

DISCUSSION review,54 which highlights problems with GP and nurse recruitment. The one health board area from which we did not recruit any practices to the feasibility trial is reported to have the highest GP vacancy rates outside the three island boards. The number of practices taken over by health boards in Scotland (mainly as a result of recruitment problems) has been steadily increasing since 2013. The Audit Scotland report also highlighted high levels of sickness absence in the NHS in Scotland, with major challenges for the future of the NHS workforce, particularly in the primary and community care setting, in which one in every two nurses is aged ≥ 50 years. Patient recruitment was more feasible within this study design. Nurses were asked to only hand out study packs to patients with minimal advice. The patients were asked to complete questionnaires and return these before leaving the surgery or by post. Patients who completed questionnaires then received another questionnaire by post at 8 weeks. The aim was to obtain 10 completed questionnaires per nurse. Overall, patient recruitment and follow-up (retention) was acceptable, but was much lower in the phase 2 follow-up. However, in this study, this was affected by the delayed timeline of the study, meaning that some follow-up questionnaires were not issued by practices, as the study had ended. There was significant nurse reluctance to have their consultations recorded. This was reported by nurses as a perceived problem in obtaining patient consent, which resulted in some nurses refusing to undertake this part of the study. Even nurses who did consent to taking part were reluctant to approach patients and did not recruit many, even though they reported that all patients who were approached consented to their consultation being recorded. This would indicate that it is a nurse issue and not a patient issue. However, any future study of fidelity would have to involve a different methodological approach or an understanding of nurse reluctance that could then be addressed. The Patient Centred Assessment Method versus other tools or interventions to promote holistic assessment We believe that we have already made strong arguments that nurse use of depression screening tools has been ineffective and may have led to underdetection of mental health issues in patients with LTCs. However, as with the existence of the INTERMED, there are some other tools that may be considered as promoting holistic assessment, and it is important to reflect on the PCAM in relation to these other tools. We found reference to the use of the Family Nurse Partnership Tool55 among adults with learning disability and, although it includes attention to social circumstances, it also includes using a battery of other mental health assessment tools that we did not find appropriate for PNs. We are not aware that this approach has either been specifically designed for use in primary care or tested for use in primary care, whereas the PCAM tool has been specifically designed for use in primary care. None of these was deemed appropriate for the purpose of PN assessment of biopsychosocial needs in primary care settings. The HNA has not been fully evaluated in any clinical trials and has not been developed for use in primary care by patients with LTCs.

NPT is a conceptual framework to explain implementation of innovations in health care generic 5 ml fml forte mastercard. How people understand the innovation and its purpose (coherence). What decisions people take about using it, based on perceived advantages (cognitive participation). What people do to bring the innovation into everyday use (collective action). How the innovation is reviewed, modified or abandoned (reflexive monitoring). Sample size and power We derived data on the number of emergency admissions per patient, the primary outcome for this study, from routine data, in principle, for all non-dissenting patients. We expected SAIL to yield data on about 250,000 people. We excluded people not registered with a study practice on day 1, and defined their final date in the study as the earliest of the date of death, the date of registration with another practice (including another study practice) or the end of the study. The Consolidated Standards of Reporting Trials (CONSORT) flow chart (see Figure 3) recorded the numbers dissenting or withdrawing from the study, or otherwise leaving before its end. In considering sample sizes for postal questionnaires measuring secondary outcomes, we identified few general practice studies with ICCs of > 0. This led us to seek 800 respondents in each of the three questionnaire phases to detect differences in resource use between current intervention and control practices across the spectrum of risk. This would allow us to have 80% power when using a 5% significance level to detect a difference of 15% in the proportion of patients at defined risk levels receiving specified resources. Although SAIL yielded data on our primary outcome for non-dissenting participants, some individual data were missing. We summarised the frequency of missing data for each variable, which directly influenced sample sizes, and hence the statistical power of analyses. Project management We organised the review, approval and adoption of the trial by STU. In undertaking the trial, we adhered to all relevant STU SOPs in the conduct, management and monitoring of the study. We set up a Research Management Group (RMG), which was responsible for the strategic management of the trial. This RMG met quarterly and comprised the chief investigator, all co-applicants, all research staff, two service users and two local participating GPs. We managed operational issues through a monthly research team meeting which was made up of the researchers, clerical support, the principal investigator and one of the co-applicants. We set up a data management task and finish group to oversee all data management and analysis issues. We used the STU SOP on data management to develop a data management plan, outlining details of data entry, coding, security and storage, including any related processes to promote data quality. We set up an independent Trial Steering Committee (TSC) that provided overall oversight and ensured the rigorous conduct of the trial. In addition, we organised an independent Data Monitoring and Ethics Committee (DMEC) which had oversight of the data management and analysis issues and which fed information into the TSC. We organised TSC meetings every 6 months, with the DMEC being held just prior to these meetings. The TSC was made up of an independent chairperson with an interest in emergency care, an academic in primary care, a consultant in public health, a statistician and two service users (with no previous involvement in the trial). The DMEC was chaired by the statistician with experience in trials and was also attended by the consultant in public health, the academic GP and the two service users.
