Unveiling the Impact of Lean Leadership on Continuous Improvement Maturity: A Scoping Review

Purpose

Lean Management (LM) is a process improvement approach with growing interest from healthcare organizations. Obtaining a culture of continuous improvement is a primary objective of LM, and a culture of continuous improvement indicates a mature LM approach, and here leadership plays a central role. However, a comprehensive overview of leadership activities influencing LM maturity is lacking. This study aims to identify leadership activities associated with continuous improvement and, thus, LM, maturity.

Methods

Following the PRISMA guidelines, a scoping literature review of peer-reviewed articles was conducted in twenty healthcare management journals. The search provided 466 articles published up until 2023. During the selection process, 23 studies were included in the review. The leadership activities related to continuous improvement maturity were identified using the grounded theory approach and data coding.

Results

The analysis highlighted a total of 58 leadership activities distributed across nine themes of LM leadership. Next, analysing leadership activities concerning the different maturity levels revealed three maturity stages: beginner, intermediate, and expert. Based on the findings, we propose a framework that guides suitable leadership activities at the various stages of LM maturity. The framework provides leaders in healthcare with a practical overview of actions to facilitate the growth of the LM approach, and the related propositions offer academics a theoretical basis for future studies.

Conclusion

This review presents the first comprehensive overview of LM leadership activities in relation to continuous improvement and LM maturity. To enhance LM maturity, leaders are encouraged to consider their leadership style, (clinical) stakeholder involvement, alignment with the organizational strategy, and their role in promoting employee autonomy.

Effects of Lean Interventions Supported by Digital Technologies on Healthcare Services: A Systematic Review

Despite the increasing utilization of lean practices and digital technologies (DTs) related to Industry 4.0, the impact of such dual interventions on healthcare services remains unclear. This study aims to assess the effects of those interventions and provide a comprehensive understanding of their dynamics in healthcare settings. The methodology comprised a systematic review following the PRISMA guidelines, searching for lean interventions supported by DTs. Previous studies reporting outcomes related to patient health, patient flow, quality of care, and efficiency were included. Results show that most of the improvement interventions relied on lean methodology followed by lean combined with Six Sigma. The main supporting technologies were simulation and automation, while emergency departments and laboratories were the main settings. Most interventions focus on patient flow outcomes, reporting positive effects on outcomes related to access to service and utilization of services, including reductions in turnaround time, length of stay, waiting time, and turnover time. Notably, we found scarce outcomes regarding patient health, staff wellbeing, resource use, and savings. This paper, the first to investigate the dual intervention of DTs with lean or lean–Six Sigma in healthcare, summarizes the technical and organizational challenges associated with similar interventions, encourages further research, and promotes practical applications.

Process mapping in healthcare: a systematic review

INTRODUCTION

Process mapping (PM) supports better understanding of complex systems and adaptation of improvement interventions to their local context. However, there is little research on its use in healthcare. This study (i) proposes a conceptual framework outlining quality criteria to guide the effective implementation, evaluation and reporting of PM in healthcare; (ii) reviews published PM cases to identify context and quality of PM application, and the reported benefits of using PM in healthcare.

METHODS

We developed the conceptual framework by reviewing methodological guidance on PM and empirical literature on its use in healthcare improvement interventions. We conducted a systematic review of empirical literature using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) methodology. Inclusion criteria were: full text empirical study; describing the process through which PM has been applied in a healthcare setting; published in English. Databases searched are: Medline, Embase, HMIC-Health Management Information Consortium, CINAHL-Cumulative Index to Nursing and Allied Health Literature, Scopus. Two independent reviewers extracted and analysed data. Each manuscript underwent line by line coding. The conceptual framework was used to evaluate adherence of empirical studies to the identified PM quality criteria. Context in which PM is used and benefits of using PM were coded using an inductive thematic analysis approach.

RESULTS

The framework outlines quality criteria for each PM phase: (i) preparation, planning and process identification, (ii) data and information gathering, (iii) process map generation, (iv) analysis, (v) taking it forward. PM is used in a variety of settings and approaches to improvement. None of the reviewed studies (N = 105) met all ten quality criteria; 7% were compliant with 8/10 or 9/10 criteria. 45% of studies reported that PM was generated through multi-professional meetings and 15% reported patient involvement. Studies highlighted the value of PM in navigating the complexity characterising healthcare improvement interventions.

CONCLUSION

The full potential of PM is inhibited by variance in reporting and poor adherence to underpinning principles. Greater rigour in the application of the method is required. We encourage the use and further development of the proposed framework to support training, application and reporting of PM.

Effects of Lean Healthcare on Patient Flow: A Systematic Review

OBJECTIVES

To assess the effects of lean healthcare (LH) on patient flow in ambulatory care and determine whether waiting time and length of stay (LOS) decrease after LH interventions.

METHODS

A systematic review was performed with close adherence to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). We searched for studies of healthcare organizations applying LH interventions within ambulatory care published between 2002 and 2018. Six databases and grey literature sources were used. Two reviewers independently screened and assessed each study. When consensus was difficult to reach, a third reviewer intervened. Finally, a summary of findings was generated.

RESULTS

Out of 5627 studies, 40 were included. Regarding LOS for all patients, 19 out of 22 studies reported a decrease. LOS for discharged patients decreased in 11 out of 13 studies, whereas LOS for admitted patients was reduced in 6 out of 7 studies. Waiting time for patients before seeing a healthcare professional decreased in 24 out of 26 studies. Waiting time to treatment and waiting time for appointments were minimized in 4 and 2 studies, respectively. Patients who left without being seen by a doctor decreased in 9 out of 12 studies. Finally, patient and staff satisfaction were measured in 8 and 2 studies, respectively, with each reporting improvements.

CONCLUSIONS

According to our findings, LH helped to reduce waiting time and LOS in ambulatory care, mainly owing to its focus on identifying and minimizing non-value added (NVA) activities. Nevertheless, evidence of the impact of LH on patient/staff satisfaction and the translation of the obtained benefits into savings is scarce among studies.

A case-based methodology for lean implementation in hospital operations

PURPOSE

Although there are general methodologies for lean implementation in manufacturing companies, a specific methodology for the implementation of lean healthcare in hospitals has not been addressed by the literature. Addressing this gap, the purpose of this paper is to develop a practice-driven methodology for implementing lean in hospital operations.

DESIGN/METHODOLOGY/APPROACH

Three case studies were conducted to collect evidence on the lean implementation process in Brazilian hospitals. From empirical evidence and literature, the implementation methodology was proposed and submitted to critical assessment by experts from the field.

FINDINGS

The process of lean implementation was very similar in all cases, triggered by strategic planning and operationalized by continuous improvement projects. On the other hand, in all cases, the lean implementation teams had to deal with employees' resistance. These findings were valuable inputs to the development of the implementation methodology. After refinement, it was proposed a feasible, useful and user-friendly methodology.

RESEARCH LIMITATIONS/IMPLICATIONS

The proposed methodology was raised from the practice through case study research. However, the proposed methodology was not fully applied, and the associated performance measures were not elaborated in this paper. Therefore, more case studies and applications will be necessary to generalize the findings.

PRACTICAL IMPLICATIONS

The methodology provides practical guidelines that support lean implementation in hospital operations. Although it demands adaptations for each specific hospital setting, this initial step may encourage hospital managers to start the lean journey.

ORIGINALITY/VALUE

This study addressed the gap in the literature regarding the lack of methodologies for implementing lean healthcare in hospital operations. The methodology synthesizes the knowledge, principles and tools of lean thinking that can be applied in hospital operations.

What Is Lean Management in Health Care? Development of an Operational Definition for a Cochrane Systematic Review

Industrial improvement approaches such as Lean management are increasingly being adopted in health care. Synthesis is necessary to ensure these approaches are evidence based and requires operationalization of concepts to ensure all relevant studies are included. This article outlines the process utilized to develop an operational definition of Lean in health care. The literature search, screening, data extraction, and data synthesis processes followed the recommendations outlined by the Cochrane Collaboration. Development of the operational definition utilized the methods prescribed by Kinsman et al. and Wieland et al. This involved extracting characteristics of Lean, synthesizing similar components to establish an operational definition, applying this definition, and updating the definition to address shortcomings. We identified two defining characteristics of Lean health-care management: (1) Lean philosophy, consisting of Lean principles and continuous improvement, and (2) Lean activities, which include Lean assessment activities and Lean improvement activities. The resulting operational definition requires that an organization or subunit of an organization had integrated Lean philosophy into the organization's mandate, guidelines, or policies and utilized at least one Lean assessment activity or Lean improvement activity. This operational definition of Lean management in health care will act as an objective screening criterion for our systematic review. To our knowledge, this is the first evidence-based operational definition of Lean management in health care.

Optimizing patient flow in a multidisciplinary haemophilia clinic using quality improvement methodology

INTRODUCTION

Multidisciplinary clinics in academic settings are often inefficient and can lead to lengthy clinic visits for patients and staff.

AIM

We aimed to use quality improvement (QI) methodology and a multidisciplinary approach to optimize outpatient comprehensive haemophilia clinic flow.

METHODS

At baseline, a multidisciplinary QI team created a key driver diagram to identify drivers of haemophilia clinic flow. Identified drivers included patient needs/scheduling, provider flow and laboratory/research requirements. From December 2016 to August 2017, value stream mapping (VSM) was used to identify barriers to clinic flow, and plan-do-study-act cycles were used to address these barriers. Interventions included (a) standardizing the order in which providers saw patients to enable time-sensitive laboratories, (b) improving HTC team meeting functionality, (c) optimizing a visual management board and implementing a flow coordinator, (d) initiating a team huddle prior to clinic start and (e) modifying the clinic appointment template. Timely laboratory draw was used as a surrogate marker of clinic flow, and VSM utilization percentage was used as an objective measure of efficiency.

RESULTS

We did not demonstrate a statistically significant improvement in timed laboratory draws; however, clinic utilization percentage increased by 30%, which resulted in adding point-of-care musculoskeletal ultrasound services without lengthening clinic duration.

CONCLUSION

Quality improvement methodology is an effective means of improving clinic utilization in a multidisciplinary clinic.

Using lean thinking to improve hypertension in a community health centre: a quality improvement report

Background

Achieving better care at lower cost in the US healthcare safety net will require federally qualified health centres (FQHC) to implement new models of team-based population healthcare. Lean thinking may offer a way to reduce the financial risk of practice transformation while increasing the likelihood of sustained improvement.

Objective

To demonstrate system-level improvement in hypertension control in a large FQHC through the situational use of lean thinking and statistical process control.

Setting

Lynn Community Health Center, the third largest FQHC in Massachusetts, USA.

Participants

4762 adult patients with a diagnosis of hypertension.

Intervention

First, we created an organisation-wide focus on hypertension. Second, we implemented a multicomponent hypertension care pathway. The lean tools of strategy deployment, standardised work, job instruction, Plan-Do-Study-Adjust, 5S and visual control were used to overcome specific obstacles in the implementation.

Measurements

The primary outcome was hypertension control, defined as last measured blood pressure <140/90. Statistical process control was used to establish baseline performance and assess special cause variation resulting from the two-step intervention.

Results

Hypertension control improved by 11.6% from a baseline of 66.8% to a 6 month average of 78.2%.

Limitations

Durability of system changes has not been demonstrated beyond the 14-month period of the intervention. The observed improvement may underestimate the effect size of the full hypertension care pathway, as two of the five steps have only been partially implemented.

Conclusions

Success factors included experienced improvement leaders, a focus on engaging front-line staff, the situational use of lean principles to make the work easier, better, faster and cheaper (in that order of emphasis), and the use of statistical process control to learn from variation. The challenge of transforming care delivery in the safety net warrants a closer look at the principles, relevance and potential impact of lean thinking in FQHCs.

Applying lean methodology to improve parenteral chemotherapy and monoclonal antibody documentation processes based on Normalisation Process Theory

Objective

To determine the impact of lean thinking on the original time required to prepare the necessary documentation in relation to the preparation of parenteral chemotherapy/monoclonal antibodies.

Method

Four pharmacists and one pharmacy technician from the oncology hospital (Malta) all participated in eight focus groups linked to the different constructs of Normalisation Process Theory (NPT): coherence, cognitive participation, collective action and reflexive monitoring. The value stream documentation process was mapped by analysing all steps in the process where each activity must add value for the patient; tools of lean thinking were applied. Points causing delay in processing were considered critical; possible changes to minimise time waste were discussed and implemented. Time spent on critical points was measured by timing in minutes each step of the process 1 month before and after the changes had been implemented and calculating the mean±SD. An audit was performed comparing the process with standard operating procedures to determine whether any steps required quality improvement.

Results

Three critical points were identified: time required to search for pharmacy patient medication records for chemotherapy/monoclonal antibodies required on the day; time to generate preparation labels; and time to generate worksheets. Overall, a total of 122±8.6 min (p=0.06) were saved per day, a 37% decrease from the original documentation time. Five deficiencies were identified in the documentation process audit; corrective action was proposed.

Conclusions

By applying lean thinking, non-value-added steps leading to time waste in the documentation process were eliminated. This concept could be implemented by using NPT as part of a strategic system to reduce waste.

Does Value Stream Mapping affect the structure, process, and outcome quality in care facilities? A systematic review

BACKGROUND

Quality improvement within health and social care facilities is needed and has to be evidence-based and patient-centered. Value Stream Mapping, a method of Lean management, aims to increase the patients' value and quality of care by a visualization and quantification of the care process. The aim of this research is to examine the effectiveness of Value Stream Mapping on structure, process, and outcome quality in care facilities.

METHODS

A systematic review is conducted. PubMed, EBSCOhost, including Business Source Complete, Academic Search Complete, PSYCInfo, PSYNDX, SocINDEX with Full Text, Web of Knowledge, and EMBASE ScienceDirect are searched in February 2016. All peer-reviewed papers evaluating Value Stream Mapping and published in English or German from January 2000 are included. For data synthesis, all study results are categorized into Donabedian's model of structure, process, and outcome quality. To assess and interpret the effectiveness of Value Stream Mapping, the frequencies of the results statistically examined are considered.

RESULTS

Of the 903 articles retrieved, 22 studies fulfill the inclusion criteria. Of these, 11 studies are used to answer the research question. Value Stream Mapping has positive effects on the time dimension of process and outcome quality. It seems to reduce non-value-added time (e.g., waiting time) and length of stay. All study designs are before and after studies without control, and methodologically sophisticated studies are missing.

CONCLUSIONS

For a final conclusion about Value Stream Mapping's effectiveness, more research with improved methodology is needed. Despite this lack of evidence, Value Stream Mapping has the potential to improve quality of care on the time dimension. The contextual influence has to be investigated to make conclusions about the relationship between different quality domains when applying Value Stream Mapping. However, for using this review's conclusion, the limitation of including heterogeneous and potentially biased results has to be considered.

The impact of sharing personalised clinical information with people with type 2 diabetes prior to their consultation: A pilot randomised controlled trial

AIM

To assess the impact of sharing personalised clinical information with people with type 2 diabetes prior to their out-patient consultation on patient involvement during the consultation, diabetes self-management self-efficacy and glycaemic control.

METHODS

A pilot three-arm randomised controlled trial. The 'intervention booklet' group received a booklet including personalised clinical information, a 'general information booklet' control group received a booklet with no personalised clinical information and a 'usual care' control group received no written information.

RESULTS

136 people took part. The intervention group were significantly more likely to have shown the booklet to a 'significant other', (48% V 23%, p<0.05), brought the booklet with them to the clinic (85% V 35%, p<0.005) and to refer to the booklet during the consultation (45% V 13%, p<0.005). No significant differences in patient involvement during the consultation, diabetes management self-efficacy or glycaemic control were found between the three groups.

CONCLUSIONS

Although participants found it useful to receive their clinical results, no differences were found in the patient outcomes measured.

PRACTICE IMPLICATIONS

Further pilot work on the timing of the intervention, who it is targeted at and what outcomes are measured is warranted before proceeding to a full-scale RCT.

Lean management in health care: definition, concepts, methodology and effects reported (systematic review protocol)

BACKGROUND

Lean is a set of operating philosophies and methods that help create a maximum value for patients by reducing waste and waits. It emphasizes the consideration of the customer's needs, employee involvement and continuous improvement. Research on the application and implementation of lean principles in health care has been limited.

METHODS

This is a protocol for a systematic review, following the Cochrane Effective Practice and Organisation of Care (EPOC) methodology. The review aims to document, catalogue and synthesize the existing literature on the effects of lean implementation in health care settings especially the potential effects on professional practice and health care outcomes. We have developed a Medline keyword search strategy, and this focused strategy will be translated into other databases. All search strategies will be provided in the review. The method proposed by the Cochrane EPOC group regarding randomized study designs, non-randomised controlled trials controlled before and after studies and interrupted time series will be followed. In addition, we will also include cohort, case-control studies, and relevant non-comparative publications such as case reports. We will categorize and analyse the review findings according to the study design employed, the study quality (low- versus high-quality studies) and the reported types of implementation in the primary studies. We will present the results of studies in a tabular form.

DISCUSSION

Overall, the systematic review aims to identify, assess and synthesize the evidence to underpin the implementation of lean activities in health care settings as defined in this protocol. As a result, the review will provide an evidence base for the effectiveness of lean and implementation methodologies reported in health care.
