Understanding implementation success: protocol for an in-depth, mixed-methods process evaluation of a cluster randomised controlled trial testing methods to improve detection of Lynch syndrome in Australian hospitals.

ABSTRACT:

Introduction

In multisite intervention trials, implementation success often varies widely across settings. Process evaluations are crucial to interpreting trial outcomes and understanding contextual factors and causal chains necessary for successful implementation. Lynch syndrome is a hereditary cancer predisposition conferring an increased risk of colorectal, endometrial and other cancer types. Despite systematic screening protocols to identify Lynch syndrome, the condition remains largely underdiagnosed. The Hide and Seek Project ('HaSP') is a cluster randomised controlled trial determining the effectiveness of two approaches to improving Lynch syndrome detection at eight Australian hospital networks. To enhance widespread implementation of optimal Lynch syndrome identification, there is a need to understand not only what works, but also why, in what contexts, and at what costs. Here we describe an in-depth investigation of factors influencing successful implementation of procedures evaluated in the HaSP trial.

Methods and analysis

A mixed-methods, theory-driven process evaluation will be undertaken in parallel to the HaSP trial. Data will include: interviews of Implementation Leads and Lynch syndrome stakeholders, pre-post implementation questionnaires, audio analysis of meetings and focus groups, observation of multidisciplinary team meetings, fidelity checklists and project log analysis. Results will be triangulated and coded, drawing on the Theoretical Domains Framework, Consolidated Framework for Implementation Research and Proctor's implementation outcomes.

Ethics and dissemination

Use of a theory-based process evaluation will enhance interpretation and generalisability of HaSP trial findings, and contribute to the implementation research field by furthering understanding of the conditions necessary for implementation success. Ethical approval has been granted and results will be disseminated via publications in peer-reviewed journals and conference presentations. At trial completion, key findings will be fed back to sites to enable refinement of intervention strategies, both in the context of Lynch syndrome and for the possible generalisability of intervention components in other genetic and broader clinical specialties.

Project description:AimsThere is currently no gold-standard definition or method for identifying suicide clusters, resulting in considerable heterogeneity in the types of suicide clusters that are detected. This study sought to identify the characteristics, mechanisms and parameters of suicide clusters using three cluster detection methods. Specifically, the study aimed to: (1) determine the overlap in suicide clusters among each method, (2) compare the spatial and temporal parameters associated with different suicide clusters and (3) identify the demographic characteristics and rates of exposure to suicide among cluster and non-cluster members.MethodsSuicide data were obtained from the National Coronial Information System. N = 3027 Australians, aged 10-24 who died by suicide in 2006-2015 were included. Suicide clusters were determined using: (1) poisson scan statistics, (2) a systematic search of coronial inquests and (3) descriptive network analysis. These methods were chosen to operationalise three different definitions of suicide clusters, namely clusters that are: (1) statistically significant, (2) perceived to be significant and (3) characterised by social links among three or more suicide descendants. For each method, the demographic characteristics and rates of exposure to suicide were identified, in addition to the maximum duration of suicide clusters, the geospatial overlap between suicide clusters, and the overlap of individual cluster members.ResultsEight suicide clusters (69 suicides) were identified from the scan statistic, seven (40 suicides) from coronial inquests; and 11 (37 suicides) from the descriptive network analysis. Of the eight clusters detected using the scan statistic, two overlapped with clusters detected using the descriptive network analysis and one with clusters identified from coronial inquests. Of the seven clusters from coronial inquests, four overlapped with clusters from the descriptive network analysis and one with clusters from the scan statistic. Overall, 9.2% (12 suicides) of individuals were identified by more than one method. Prior exposure to suicide was 10.1% (N = 7) in clusters from the scan statistic, 32.5% (N = 13) in clusters from coronial inquest and 56.8% (N = 21) in clusters from the descriptive network analysis.ConclusionEach method identified markedly different suicide clusters. Evidence of social links between cluster members typically involved clusters detected using the descriptive network analysis. However, these data were limited to the availability information collected as part of the police and coroner investigation. Communities tasked with detecting and responding to suicide clusters may benefit from using the spatial and temporal parameters revealed in descriptive studies to inform analyses of suicide clusters using inferential methods.

Project description:BackgroundTo identify context factors associated with and predicting success in the hospital accreditation process, and to contribute to the understanding of the relative relevance of context factors and their organizational level in the success of QI initiatives.MethodsAnalytical study of cases and controls in a sample of hospitals of medium and high complexity in Colombia. Cases (n = 16) are accredited hospitals by the time of preparation of the study (2016) and controls (n = 38) are similar facilities, which have not succeeded to obtain accreditation. Eligibility criteria for both groups included complexity (medium and high), having emergency services, an official quality assurance license, and being in operation for at least 15 years. Besides eligibility criteria, geographical location, and type of ownership (public/private) are used to select controls to match cases. Context measures are assessed using a survey instrument based on the MUSIQ model ("Model for Understanding Success in Quality") adapted and tested in Colombia. Statistical analysis includes descriptive measures for twenty-three context factors, testing for significant statistical differences between accredited and non-accredited hospitals, and assessing the influence and strength of association of context factors on the probability of success in the accreditation process. A multivariate model assesses the predictive probability of achieving accreditation.ResultsEighteen (78.3%) of the twenty-three context factors are significantly different when comparing cases and controls hospitals, particularly at the Microsystem level; all factors are statistically significant in favor of accredited hospitals. Five context factors are strongly associated to the achievement of accreditation but in the logistic multivariable model, only two of them remain with significant OR, one in the Macrosystem, "Availability of economic resources for QI" (OR: 22.1, p: 0,005), and the other in the Microsystem, "Involvement of physicians" (OR: 4.9, p: 0,04).ConclusionThis study has applied an instrument, based on the MUSIQ model, which allows assessing the relevance of different context factors and their organizational level in hospitals, to explain success in the accreditation process in Colombia. Internal macrosystem and microsystem seem to be more relevant than external environment factors.

Project description:BACKGROUND: With the use of medicines being a broad and extensive part of health management, mechanisms to ensure quality use of medicines are essential. Drug usage evaluation (DUE) is an evidence-based quality improvement methodology, designed to improve the quality, safety and cost-effectiveness of drug use. The purpose of this paper is to describe a national DUE methodology used to improve health care delivery across the continuum through multi-faceted intervention involving audit and feedback, academic detailing and system change, and a qualitative assessment of the methodology, as illustrated by the Acute Postoperative Pain Management (APOP) project. METHODS: An established methodology, consisting of a baseline audit of inpatient medical records, structured patient interviews and general practitioner surveys, followed by an educational intervention and follow-up audit, is used. Australian hospitals, including private, public, metropolitan and regional, are invited to participate on a voluntary basis. De-identified data collected by hospitals are collated and evaluated nationally to provide descriptive comparative analyses. Hospitals benchmark their practices against state and national results to facilitate change. The educational intervention consists of academic detailing, group education, audit and feedback, point-of-prescribing prompts and system changes. A repeat data collection is undertaken to assess changes in practice.An online qualitative survey was undertaken to evaluate the APOP program. Qualitative assessment of hospitals' perceptions of the effectiveness of the overall DUE methodology and changes in procedure/prescribing/policy/clinical practice which resulted from participation were elicited. RESULTS: 62 hospitals participated in the APOP project. Among 23 respondents to the evaluation survey, 18 (78%) reported improvements in the documentation of pain scores at their hospital. 15 (65%) strongly agreed or agreed that participation in APOP directly resulted in increased prescribing of multimodal analgesia for pain relief in postoperative patients. CONCLUSIONS: This national DUE program has facilitated the engagement and participation of a number of acute health care facilities to address issues relating to quality use of medicine. This approach has been perceived to be effective in helping them achieve improvements in patient care.

Project description:AimOur aim was to evaluate the implementation process of a comprehensive cardiovascular disease prevention program in general practice, to enhance understanding of influencing factors to implementation success and sustainability, and to learn how to overcome barriers.BackgroundCardiovascular disease and its risk factors are the world's leading cause of mortality, yet can be prevented by addressing unhealthy lifestyle behavior. Nevertheless, the transition toward a prevention-oriented primary health care remains limited. A better understanding of factors facilitating or hindering implementation success and sustainability of prevention programs, and how barriers may be addressed, is needed. This work is part of Horizon 2020 project 'SPICES', which aims to implement validated preventive interventions in vulnerable populations.MethodsWe conducted a qualitative process evaluation with participatory action research approach of implementation in five general practices. Data were collected through 38 semi-structured individual and small group interviews with seven physicians, 11 nurses, one manager and one nursing assistant, conducted before, during, and after the implementation period. We applied adaptive framework analysis guided by RE-AIM Qualitative Evaluation for Systematic Translation (RE-AIM QuEST) and Consolidated Framework for Implementation Research (CFIR).FindingsMultiple facilitators and barriers affected reach of vulnerable target populations: adoption by primary health care providers, implementation and fidelity and intention to maintain the program into routine practice. In addition, our study revealed concrete actions, linked to implementation strategies, that can be undertaken to address identified barriers. Prioritization of prevention in general practice vision, ownership, and shared responsibility of all team members, compatibility with existing work processes and systems, expanding nurse's roles and upskilling competence profiles, supportive financial and regulatory frameworks, and a strong community - health care link are crucial to increase implementation success and long-term maintenance of prevention programs. COVID-19 was a major barrier to the implementation. RE-AIM QuEST, CFIR, and participatory strategies are useful to guide implementation of prevention programs in primary health care.

Project description:BackgroundFor successful implementation of an innovation within a complex adaptive system, we need to understand the ways that implementation processes and their contexts shape each other. To do this, we need to explore the work people do to make sense of an innovation and integrate it into their workflow and the contextual elements that impact implementation. Combining Normalization Process Theory (NPT) with the Consolidated Framework for Implementation Research (CFIR) offers an approach to achieve this. NPT is an implementation process theory that explains how changes in the way people think about and use an innovation occurs, while CFIR is a framework that categorizes and describes contextual determinants across five domains that influence implementation. We demonstrate through a case example from our prior research how we integrated NPT and CFIR to inform the development of the interview guide, coding manual, and analysis of the findings.MethodsIn collaboration with our stakeholders, we selected NPT and CFIR to study the implementation process and co-developed an interview guide to elicit responses that would illuminate concepts from both. We conducted, audio-recorded, and transcribed 28 interviews with various professionals involved with the implementation. Based on independent coding of select transcripts and team discussion comparing, clarifying, and crystallizing codes, we developed a coding manual integrating CFIR and NPT constructs. We applied the integrated codes to all interview transcripts.ResultsOur findings highlight how integrating CFIR domains with NPT mechanisms adds explanatory strength to the analysis of implementation processes, with particular implications for practical strategies to facilitate implementation. Multiple coding across both theoretical frames captured the entanglement of process and context. Integrating NPT and CFIR enriched understandings of how interactions between implementation processes and contextual determinants shaped each other during implementation.ConclusionThe integration of NPT and CFIR provides guidance to identify and explore complex entangled interactions between agents, processes, and contextual conditions within and beyond organizations to embed innovations into routine practices. Nuanced understandings gained through this approach moves understandings beyond descriptions of determinants to explain how change occurs or not during implementation. Mechanism-based explanations illuminate concrete practical strategies to support implementation.

Project description:BackgroundThe nursing process was initially adopted from the general system theory, and was developed and implemented in the field of education. There is a demand to implement the nursing process in practical care in every health institution, but the perception remains that it is time-consuming and impractical. If the nursing process is not valued and not used, nurses may continue to intervene on the basis of a medical diagnosis rather than on the basis of a rational nursing Process steps. In any of the steps, oversight or omission can result in less than optimal nursing care. The purpose of this study was to assess implementation and factors affecting the nursing process among nurses working in selected government hospitals in Southwest Ethiopia.MethodsAn institution-based cross-sectional descriptive study was conducted from March 10 to April 1, 2015 in three hospitals in southwest Ethiopia using self-administered questionnaires. This study included a total of 138 nurses using simple random sampling. Data were classified, coded and entered into epidemiological information version 3.5.3, and exported to the statistical package for social science version 20 for analysis, descriptive statistics were used to describe the variables, bivariable and multivariable logistic regression were used to see the effect of each variable on the dependent variable.ResultThe nursing process was found to be 73.9% implemented. Compared to a Bachelor of Science nurses', the likelihood of implementing the nursing process was less likely among diploma nurses. Nurses working in administratively supported hospitals implemented the nursing process more compared to those without administrative support. The nursing process had been implemented higher by trained nurses compared to untrained nurses.ConclusionThe implementation of nursing process was good where; nearly seven in every ten nurses implemented the nursing process. Low educational qualification, lack of training, and non-supportive hospital administration were predictors of the nursing process implementation. The health service management, in collaboration with Ethiopian nursing/professional associations and international governmental and non-governmental organizations should give continuous on the job professional development education, and develop nursing practice guidelines.
