A mixed methods multiple case study to evaluate the implementation of a care pathway for colorectal cancer surgery using extended normalization process theory

Implementing a tobacco-free workplace program at a substance use treatment center: a case study

BACKGROUND

People with substance use disorders smoke cigarettes at much higher rates than the general population in the United States and are disproportionately affected by tobacco-related diseases. Many substance use treatment centers do not provide evidence-based tobacco cessation treatment or maintain comprehensive tobacco-free workplace policies. The goal of the current work is to identify barriers and facilitators to a successful and sustainable implementation of a tobacco-free workplace program, which includes a comprehensive tobacco-free policy and evidence-based cessation treatment services, in a substance use treatment center.

METHODS

This study is based on an ethnographic approach and uses a qualitative case study design. Data were collected via interviews with staff (n = 6) and clients (n = 16) at the substance use treatment center and site visits (n = 8). Data were analyzed using thematic analysis guided by the extended Normalization Process Theory designed to inform the implementation of innovations in healthcare practice.

RESULTS

Staff at the substance use treatment center supported the implementation of the program and shared a good understanding of the purpose of the intervention and its potential benefits. However, the study identified significant challenges faced by the center during implementation, including widespread tobacco use among clients, contributing to attitudes among staff that tobacco cessation was a low-priority problem due to a perceived lack of interest in quitting and inability to quit among their clients. We identified several factors that contributed to changing this attitude, including provision of tobacco training to staff, active leadership support, low number of staff members who smoked, and access to material resources, including nicotine replacement products. The implementation and active enforcement of a comprehensive tobacco-free workplace program contributed to a gradual change in attitudes and improved the provision of evidence-based tobacco cessation care at the substance use treatment center.

CONCLUSIONS

Substance use treatment centers can integrate tobacco cessation practices in their daily operations, despite multiple challenges they face due to the complex behavioral health and socioeconomic needs of their clients. With proper support, substance use treatment centers can provide much needed tobacco cessation care to their clients who are disproportionately affected by tobacco-related health conditions and systemic health inequities.

Developing an implementation research logic model: using a multiple case study design to establish a worked exemplar

BACKGROUND

Implementation science frameworks explore, interpret, and evaluate different components of the implementation process. By using a program logic approach, implementation frameworks with different purposes can be combined to detail complex interactions. The Implementation Research Logic Model (IRLM) facilitates the development of causal pathways and mechanisms that enable implementation. Critical elements of the IRLM vary across different study designs, and its applicability to synthesizing findings across settings is also under-explored. The dual purpose of this study is to develop an IRLM from an implementation research study that used case study methodology and to demonstrate the utility of the IRLM to synthesize findings across case sites.

METHOD

The method used in the exemplar project and the alignment of the IRLM to case study methodology are described. Cases were purposely selected using replication logic and represent organizations that have embedded exercise in routine care for people with cancer or mental illness. Four data sources were selected: semi-structured interviews with purposely selected staff, organizational document review, observations, and a survey using the Program Sustainability Assessment Tool (PSAT). Framework analysis was used, and an IRLM was produced at each case site. Similar elements within the individual IRLM were identified, extracted, and re-produced to synthesize findings across sites and represent the generalized, cross-case findings.

RESULTS

The IRLM was embedded within multiple stages of the study, including data collection, analysis, and reporting transparency. Between 33-44 determinants and 36-44 implementation strategies were identified at sites that informed individual IRLMs. An example of generalized findings describing "intervention adaptability" demonstrated similarities in determinant detail and mechanisms of implementation strategies across sites. However, different strategies were applied to address similar determinants. Dependent and bi-directional relationships operated along the causal pathway that influenced implementation outcomes.

CONCLUSIONS

Case study methods help address implementation research priorities, including developing causal pathways and mechanisms. Embedding the IRLM within the case study approach provided structure and added to the transparency and replicability of the study. Identifying the similar elements across sites helped synthesize findings and give a general explanation of the implementation process. Detailing the methods provides an example for replication that can build generalizable knowledge in implementation research.

Patient involvement in clinical pathway development, implementation and evaluation - A scoping review of international literature

OBJECTIVE

Although various pathway design methods recognize patients as stakeholders, an overview of current practice is lacking. This article describes the results of a literature review assessing patient involvement in clinical cancer pathway development, implementation and evaluation.

METHODS

A scoping review was conducted following PRISMA-ScR. Two databases were searched to identify studies published in English between 2014 and 2021.

RESULTS

Of 12841articles identified 22 articles met the inclusion criteria and reported on one or more of the three phases: development phase (N = 2), implementation (N = 4), evaluation (N = 11), development/evaluation (N = 3), and implementation/evaluation (N = 2) of clinical pathways. The numbers of involved patients ranged from 10 to 793, and the reported methods varied considerably.

CONCLUSION

This review presents a synthesis of methods for involving patients in the clinical pathway lifecycle. No relationship was found between methods and the number of involved patients or between pathway complexity and methods. Although patients are seen as valuable stakeholders in the pathway design, to involve them in practice using the best practice can be improved.

PRACTICE IMPLICATIONS

The lack of a clear justification for the choice of methods and number of involved patients calls for further research and framework development to inform pathway developers.

The impact of additional allied health staffing on rehabilitation outcomes at discharge from a sub-acute geriatric evaluation and management unit: A quasi-experimental, pre-post intervention study

OBJECTIVE

The purpose of this study was to examine the impact of increasing allied health staffing levels on patient and health service outcomes across 1) all Geriatric Evaluation and Management patients, and 2) Geriatric Evaluation and Management patients discharged to home in the community.

DESIGN

Quasi-experimental, pre-post intervention study.

SETTING

Two sub-acute hospital units in an Australian, tertiary health service.

SUBJECTS

Data related to patients admitted to the study units, who were classified as Geriatric Evaluation and Management patients.

INTERVENTIONS

Comparison of therapy time across two units with a differential in staffing allocation over a six-month trial period.

MAIN MEASURES

Primary outcomes: length of stay, readmission rate, and improvement on the Functional Independence Measure. Secondary outcomes: total cost of admission per patient and number of allied health sessions.

RESULTS

Data were analysed for 214 patients (mean age = 79.9, standard deviation (SD) = 9.4 years, mean Functional Independence Measure (FIM = 64.9, SD = 21.2) admitted to the intervention unit, and 199 patients (mean age = 81.3, SD = 8.5, mean FIM = 64.2, SD = 24.0) admitted to the control unit. The overall difference in staffing allocation between the control and intervention units for the trial period was 21%. There was no statistically significant difference between units in subacute length of stay (Adj Coef = -0.10 days, 95%CI = -0.39 to 0.19), rate of readmission (OR = 1.0, 95%CI = 0.5 to 2.0) or change in function (Coef = 1.42 FIM change score, 95%CI = -2.4 to 5.3).

CONCLUSIONS

Increasing allied health staffing allocation to a unit over six-months did not impact change in function or length of stay for patients admitted for Geriatric Evaluation and Management.

Continuing to enhance the quality of case study methodology in health services research

Case study methodology has grown in popularity within Health Services Research (HSR). However, its use and merit as a methodology are frequently criticized due to its flexible approach and inconsistent application. Nevertheless, case study methodology is well suited to HSR because it can track and examine complex relationships, contexts, and systems as they evolve. Applied appropriately, it can help generate information on how multiple forms of knowledge come together to inform decision-making within healthcare contexts. In this article, we aim to demystify case study methodology by outlining its philosophical underpinnings and three foundational approaches. We provide literature-based guidance to decision-makers, policy-makers, and health leaders on how to engage in and critically appraise case study design. We advocate that researchers work in collaboration with health leaders to detail their research process with an aim of strengthening the validity and integrity of case study for its continued and advanced use in HSR.

[Evaluation of the Effectiveness of a Standard Operating Procedure (SOP) for the Perioperative Management of Colorectal Surgery]

INTRODUCTION

In recent years, perioperative care of patients after colorectal surgery has been increasingly standardised according to the fast-track concept and is accepted as a structured method of care to reduce perioperative complications. Indeed, initial studies have indicated that there is a long-term favourable effect on the oncological outcome, if the adherence to the individual measures is at least 70%. Even though there is unambiguous evidence for the efficacy of the modern perioperative treatment concept, it is often difficult to comply with the protocol during normal clinical work, particularly in Germany. The objective of this study was to record the rate of compliance before and after the introduction of the SOP and to evaluate its efficacy.

METHODS

We performed a retrospective analysis of the patient data after all elective colorectal surgery in the Bonn University Hospital from 2017 to 2020. 153 patients were operated on before the implementation of the SOP in January 2019 (group I); the remaining 153 patients were operated on after the implementation of the SOP and received appropriate care (group II). Compliance to the protocol was analysed for both the individual key interventions and the overall concept.

RESULTS

There was significant improvement in the compliance for both the individual measures (prehabilitation group I: 5.9%, group II: 42.5%, p < 0.001; preparation of the intestine I: 16.5%, II: 73.9%, p < 0.001; intraoperative volume management I: 14,00 ml/kg BW/h, II: 9.12 ml/kg BW/h, p < 0.001, BW: body weight; minimally invasive surgical technique I: 53.6%, II: 73.9%, p < 0.001; etc.) and for the overall perioperative treatment concept (I: 39%, II: 54%, p = 0.02). However, we fell far short of compliance of at least 70%. Nevertheless, patient autonomy was achieved earlier after introduction of the SOP (I: day 15, II: day 9, p < 0.001) and the postoperative hospital stay was shortened (I: 14 [6 - 99] days, II 11 [4 - 64] days; p = 0.007).

CONCLUSION

Although the implementation of the SOP led to significant improvements, further optimisation is required to attain the recommended protocol compliance of 70%. Measures within the hospital could include foundation of an interdisciplinary fast-track team and a specialised nurse as the connecting link between the patients, nursing and physicians. On the other hand, implementation throughout Germany can only be achieved by more influential actions. One possible support would be the S3 guideline on perioperative management of gastrointestinal tumours, which is under development. This could, for example, be used to support argumentation with funding providers.
