STUDY D: NURSE AND PATIENT PERCEPTIONS OF USING THE PATIENT CENTRED ASSESSMENT METHOD In addition to role playing buy cheap losartan 25mg, and useful presentations purchase losartan 25mg with amex, participants spoke of the value of having time to explore the PCAM tool in relation to their own patients and real clinical cases. Nurse interview, participant 275 In summary, a multifaceted approach to training, which integrated key information, role playing and opportunities to apply the training to real consultations, was useful for nurse participants. Use of the Patient Centred Assessment Method in consultations The general implementation of the PCAM tool into the consultations appeared to have gone well and without many challenges. Some described that it took a little time and practice to fully integrate the PCAM tool into their consultation in a way that felt naturalistic: Now, yes, now. Nurse interview, participant 41 Some nurse participants described the PCAM as being a close fit with their current practice-wide approach, and for those participants it was straightforward to include the PCAM tool, and it was described as helping to formalise the consultation. Nurse interview, participant 41 Participants talked about how certain domains took a little more practice and review to include in their consultation style than others. Some were struggling to ask questions around mental health, and others mentioned that it felt awkward getting used to asking questions about finances: The only thing was the financial one I found a bit. Again there were certain people that are more than happy to sort of divulge things without you asking too much, and others that it just seemed completely inappropriate to be asking about their financial situation. Nurse interview, participant 177 Interestingly, this project was happening alongside another initiative, House of Care (HoC), in some of the practices. Some had incorporated the PCAM into their HoC activities, and described using the PCAM as a tool to help achieve their HoC goals. Nurse Interview, participant 745 Overall, it appears that the PCAM tool was fairly easily integrated into consultations, although some participants reflected that the process of integration took some time and support. Relationship with patients The nurse participants in this study all described the use of the PCAM as a positive influence on the quality of the relationships they have with patients. The PCAM was seen as providing a tool to help guide and encourage that open communication, and for some nurse participants, it had challenged their assumptions about which patients might be facing difficulties, particularly as they came to learn that some patients who they had assumed were coping, were not. Participants were sometimes frustrated, with a perception that patients were not paying attention or not following recommendations. Nurse interview, participant 745 When nurse participants were able to find out about issues they had not known their patient was facing, and to find ways to work with that patient to connect them to resources or troubleshoot problems, they reported satisfaction in feeling that it improved the quality of the care they could provide.

STUDY D: NURSE AND PATIENT PERCEPTIONS OF USING THE PATIENT CENTRED ASSESSMENT METHOD opportunity to support patients in relation to those concerns. And to look at them as two separate issues is not the way forward, you have to look at it as a holistic. If you can sort that out or help them, you know, even to help them manage their own needs and give them some kind of direction, that has a huge impact on their health. Nurse interview, participant 745 In addition, the nurse participants described times when the PCAM identified needs that the nurse could not address, even though they make onwards referrals. However, the participants described the value in knowing information about the patient that might influence the care they provided to the patient, 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.

Owing to the small number of data available for meta-analysis purchase losartan 50 mg, meaningful interpretation of the evidence base for non-asthma physical health conditions is limited generic losartan 50mg amex. Pooled ESs are presented in Table 4 for completeness. Mental health conditions Eighteen studies evaluated self-care support for children and young people with mental health conditions. The flow of studies through the review is depicted in Figure 16. Pooled effects for each outcome are reported in Table 5. Meta-analysis of all mental health studies demonstrated that self-care support was associated with minimal but statistically significant improvements in QoL, with moderate variation across trials.

RESULTS The meta-analyses showed no significant effects on hospital admissions, ED visits or total costs. Meaningful interpretation of total cost data was limited by a small number of comparisons (n = 8) and high variation across trials. Owing to a lack of data, permutation plots were not calculated for total costs. Fourteen comparisons were eligible for inclusion in a permutation plot charting the effects of self-care support on QoL and hospital admissions for mental health (Figure 17); 10 of these comparisons originated from RCTs with adequate allocation concealment. When hospital admissions were plotted against patient outcomes, the majority of comparisons were located in the lower left-hand quadrant, suggesting that self-care support can reduce utilisation for children and young people with mental health conditions without compromising QoL. A minority of studies were located in the lower right-hand quadrant, suggesting reduced hospital admissions but a marginally compromised QoL. As stated previously, data were limited and findings must be treated with caution. Nine comparisons were eligible for inclusion in a permutation plot charting ED visits against patient outcomes (Figure 18); seven were from RCTs with adequate allocation concealment. Limited data mean that these results must be treated with caution. Behavioural difficulties Five studies evaluated self-care support for children and young people with behavioural difficulties. The flow of studies through the review is depicted in Figure 19. Owing to the small number of data available for meta-analysis, meaningful interpretation of the evidence base for non-asthma physical health conditions is limited.

Studies were categorised according to whether the self-care intervention targeted children (aged 0–12 years), adolescents (aged 13–18 years) or both (Table 8).

Self-care support was associated with a statistically significant but minimal reduction in ED use for children. Irrespective of the target age group, self-care support had no statistically significant effects on hospital admissions or total costs. Variation in the magnitude of ESs observed across the three subgroups will in part reflect differences in the number of studies available and the precision of the pooled estimates.

Parents are certain of the value of therapies discount 25mg losartan with amex, although they may experience difficulties with provision and may seek (additional) private provision purchase losartan 25mg visa. Therapy interventions are conceived as three components: the therapist, the procedures/equipment, etc. They are believed to be highly complex and poorly understood. Although participation is widely endorsed as a core intervention objective of therapy interventions, its suitability, or appropriateness, as an outcome measure was questioned. Other child and/or parent outcomes were identified as more or equally important. Notions of intermediate outcomes – in terms of body structure/function, and the achievement of activities – were regarded as important and not counter to participation-focused approaches. Among therapists, research on intervention effectiveness was (cautiously) welcomed. A number of methodological challenges were identified. A portfolio of study designs – quantitative and qualitative, experimental and observational – was called for, and which included economic evaluation and clear pathways to impact. Limitations: The study was not successful in recruiting children and young people. Further work is required to elucidate the views of this key stakeholder group. Conclusions: Therapy interventions are poorly understood. There was strong support, tempered a little by concerns among some about the feasibility of demonstrating impact, for investment in research.
