Developing New Methods for Person-Centred Approaches to Adjudicate Context-Mechanism-Outcome Configurations in Realist Evaluation.

Realist evaluation provides a general method of evaluating the application of interventions including policy, legislation, projects, and new processes in social settings such as law enforcement, healthcare and education. Realist evaluation focuses on what about interventions works, for whom, and in what circumstances, and there is a growing body of work using realist evaluation to analyse interventions in healthcare organizations, including those using Lean Six Sigma improvement methodologies. Whilst realist evaluation facilitates the analysis of interventions using both qualitative and quantitative research, there is little guidance given on methods of data collection and analysis. The purpose of this study is to address this lack of guidance through detailing the use of innovative person-centred methods of data collection and analysis in a realist evaluation that enabled us to understand the contribution of Lean Six Sigma to person-centred care and cultures. This use of person-centred principles in the adjudication of identified program theories has informed novel methods of collecting and analysing data in realist evaluation that facilitate a person-centred approach to working with research participants and a way of making the implicit explicit when adjudicating program theory.

A Realist Inquiry to Identify the Contribution of Lean Six Sigma to Person-Centred Care and Cultures.

A lack of fidelity to Lean Six Sigma's (LSS) philosophical roots can create division between person-centred approaches to transforming care experiences and services, and system wide quality improvement methods focused solely on efficiency and clinical outcomes. There is little research into, and a poor understanding of, the mechanisms and processes through which LSS education influences healthcare staffs' person-centred practice. This realist inquiry asks 'whether, to what extent and in what ways, LSS in healthcare contributes to person-centred care and cultures'. Realist review identified three potential Context, Mechanism, Outcome configurations (CMOcs) explaining how LSS influenced practice, relating to staff, patients, and organisational influences. Realist evaluation was used to explore the CMOc relating to staff, showing how they interacted with a LSS education Programme (the intervention) with CMOc adjudication by the research team and study participants to determine whether, to what extent, and in what ways it influenced person-centred cultures. Three more focused CMOcs emerged from the adjudication of the CMOc relating to staff, and these were aligned to previously identified synergies and divergences between participants' LSS practice and person-centred cultures. This enabled us to understand the contribution of LSS to person-centred care and cultures that contribute to the evidence base on the study of quality improvement beyond intervention effectiveness alone.

Evaluation of the impact of an augmented model of The Productive Ward: Releasing Time to Care on staff and patient outcomes: a naturalistic stepped-wedge trial.

BACKGROUND: Improving the quality and efficiency of healthcare is an international priority. A range of complex ward based quality initiatives have been developed over recent years, perhaps the most influential programme has been Productive Ward: Releasing Time to Care. The programme aims to improve work processes and team efficiency with the aim of 'releasing time', which would be used to increase time with patients ultimately improving patient care, although this does not form a specific part of the programme. This study aimed to address this and evaluate the impact using recent methodological advances in complex intervention evaluation design. METHOD: The objective of this study was to assess the impact of an augmented version of The Productive Ward: Releasing Time to Care on staff and patient outcomes. The design was a naturalistic stepped-wedge trial. The setting included fifteen wards in two acute hospitals in a Scottish health board region. The intervention was the Productive Ward: Releasing Time to Care augmented with practice development transformational change methods that focused on staff caring behaviours, teamwork and patient feedback. The primary outcomes included nurses' shared philosophy of care, nurse emotional exhaustion, and patient experience of nurse communication. Secondary outcomes covered additional key dimensions of staff and patient experience and outcomes and frequency of emergency admissions for same diagnosis within 6 months of discharge. RESULTS: We recruited 691 patients, 177 nurses and 14 senior charge nurses. We found statistically significant improvements in two of the study's three primary outcomes: patients' experiences of nurse communication (Effect size=0.15, 95% CI; 0.05 to 0.24), and nurses' shared philosophy of care (Effect size =0.42, 95% CI; 0.14 to 0.70). There were also significant improvements in secondary outcomes: patients' overall rating of ward quality; nurses' positive affect; and items relating to nursing team climate. We found no change in frequency of emergency admissions within six months of discharge. CONCLUSIONS: We found evidence that the augmented version of The Productive Ward: Releasing Time to Care Intervention was successful in improving a number of dimensions of nurse experience and ward culture, in addition to improved patient experience and evaluations of the quality of care received. Despite these positive summary findings across all wards, intervention implementation appeared to vary between wards. By addressing the contextual factors, which may influence these variations, and tailoring some elements of the intervention, it is likely that greater improvements could be achieved.

Exploring the impact and use of patients' feedback about their care experiences in general practice settings-a realist synthesis.

Background: Policy encourages health care providers to listen and respond to feedback from patients, expecting that it will enhance care experiences. Enhancement of patients' experiences may not yet be a reality, particularly in primary health care settings. Objective: To identify the issues that influence the use and impact of feedback in this context. Design and Setting: A realist synthesis of studies of the use of patient feedback within primary health care settings. Methods: Structured review of published studies between 1971 and January 2015. Results: Eighteen studies were reported in 20 papers. Eleven studies reported patient survey scores as a primary outcome. There is little evidence that formal patient feedback led to enhanced experiences. The likelihood of patient feedback to health care staff stimulating improvements in future patients' experiences appears to be influenced predominantly by staff perceptions of the purpose of such feedback; the validity and type of data that is collected; and where, when and how it is presented to primary health care teams or practitioners and teams' capacity to change. Conclusions: There is limited research into how patient feedback has been used in primary health care practices or its usefulness as a stimulant to improve health care experience. Using a realist synthesis approach, we have identified a number of contextual and intervention-related factors that appear to influence the likelihood that practitioners will listen to, act on and achieve improvements in patient experience. Consideration of these may support research and improvement work in this area.

The information and support needs of patients discharged after a short hospital stay for treatment of low-risk Community Acquired Pneumonia: implications for treatment without admission.

BACKGROUND: There is increasing evidence that patients with low-risk community acquired pneumonia (CAP) can be effectively treated as outpatients. This study aimed to explore patients' experiences of having pneumonia and seeking health care; their perceptions of the information provided by health professionals; how they self managed at home; their information and support needs; and their beliefs and preferences regarding site of care. METHODS: We conducted qualitative, semi-structured interviews with 15 patients who had a confirmed diagnosis of low-risk CAP and had received fewer than 3 days hospital care. Interviews were audio recorded and transcribed, and data were analysed thematically. RESULTS: Most patients left hospital with no clear understanding of pneumonia, its treatment or follow-up and most identified additional-other specific information needs when they got home. Some were unable to independently address their activities of daily living in their first days at home.Main concerns after discharge related to the cause and implications of pneumonia, symptom trajectory and prevention of transmission. Most sought advice from their GP in their first days at home, and indicated they would have appreciated a follow-up phone call or visit to discuss their concerns.Patients' preferences for site of care varied and appeared to be influenced by beliefs about safety (fear of rapid deterioration at home or acquiring an infection in hospital), family burden, access to support, or confidence in home-care services. Those who received intravenous (IV) medication were more likely to state a preference for hospital care. CONCLUSION: Trends to support community-based treatment of CAP should be accompanied by increased attention to the information and support needs of patients who go home to self-manage. Although some information needs can be anticipated and addressed on diagnosis, specific needs often do not become apparent until patients return home, so some access to information and support in the community is likely to be necessary. Our finding that patients who received IV treatment for low-risk CAP were concerned about the relative safety of home-based care highlights the potential importance of the inferences patients make from treatment modalities, and also the need to ensure that patients' expectations and understandings are managed effectively.
