Waste savings in patient transportation inside large hospitals using lean thinking tools and logistic solutions

Managing inpatient bed setup: an action-research approach using lean technical practices and lean social practices

PURPOSE

This article aims to introduce a guide to improving hospital bed setup by combining lean technical practices (LTPs), such as kaizen and value stream mapping (VSM) and lean social practices (LSPs), such as employee empowerment.

DESIGN/METHODOLOGY/APPROACH

Action research approach was employed to analyze the process of reconfiguration of bed setup management in a Brazilian public hospital.

FINDINGS

The study introduces three contributions: (1) presents the use of VSM focused specifically on bed setup, while the current literature presents studies mainly focused on patient flow management, (2) combines the use of LSPs and LTPs in the context of bed management, expanding current studies that are focused either on mathematical models or on social and human aspects of work, (3) introduces a practical guide based on six steps that combine LSPs and LSPs to improve bed setup management.

RESEARCH LIMITATIONS/IMPLICATIONS

The research focused on the analysis of patient beds. Surgical beds, delivery, emergency care and intensive care unit (ICU) were not considered in this study. In addition, the process indicators analyzed after the implementation of the improvements did not contemplate the moment of the COVID-19 pandemic. Finally, this research focused on the implementation of the improvement in the context of only one Brazilian public hospital.

PRACTICAL IMPLICATIONS

The combined use of LSPs and LTPs can generate considerable gains in bed setup efficiency and consequently increase the capacity of a hospital to admit new patients, without the ampliation of the physical space and workforce.

SOCIAL IMPLICATIONS

The improvement of bed setup has an important social character, whereas it can generate important social benefits such as the improvement of the admission service to patients, reducing the waiting time, reducing hospitalization costs and improving the hospital capacity without additional physical resources. All these results are crucial for populations, their countries and regions.

ORIGINALITY/VALUE

While the current literature on bed management is more focused on formal models or pure human and social perspectives, this article brings these two perspectives together in a single, holistic framework. As a result, this article points out that the complex bed management problem can be efficiently solved by combining LSPs and LTPs to present theoretical and practical contributions to the important social problem of hospital bed management.

Lean Six Sigma in Healthcare: A Systematic Literature Review on Motivations and Benefits

While Lean Six Sigma (LSS) has been applied extensively in healthcare organisations, there has been limited research on the trends of LSS application in healthcare in recent years. This paper aims to present the key motivations and benefits of LSS in healthcare with a view to highlighting the types of problems that LSS in healthcare can aid in solving. The authors used a systematic literature review (SLR) approach to achieving the article’s purpose. Peer-reviewed journal articles published between 2011 and 2021 are considered to achieve the study objectives. The systematic review helped the authors to identify the evolution, benefits, and motivations for LSS in healthcare. This work includes directions for managers and healthcare professionals in healthcare organisations to embark on a focused LSS journey aligned with the strategic objectives. This study is perhaps one of the most comprehensive SLRs covering a vital agenda of LSS in healthcare. This study provides all the deliverables of LSS for its successful deployment in healthcare.

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.

Reducing the Healthcare-Associated Infections in a Rehabilitation Hospital under the Guidance of Lean Six Sigma and DMAIC

The reduction of healthcare-associated infections (HAIs) is one of the most important issues in the healthcare context for every type of hospital. In three operational units of the Scientific Clinical Institutes Maugeri SpA SB, a rehabilitation hospital in Cassano delle Murge (Italy), some corrective measures were introduced in 2017 to reduce the occurrence of HAIs. Lean Six Sigma was used together with the Define, Measure, Analyze, Improve, Control (DMAIC) roadmap to analyze both the impact of such measures on HAIs and the length of hospital stay (LOS) in the Rehabilitative Cardiology, Rehabilitative Neurology, Functional Recovery and Rehabilitation units in the Medical Center for Intensive Rehabilitation. The data of 2415 patients were analyzed, considering the phases both before and after the introduction of the measures. The hospital experienced a LOS reduction in both patients with and without HAIs; in particular, Cardiology had the greatest reduction for patients with infections (-7 days). The overall decrease in HAIs in the hospital was 3.44%, going from 169 to 121 cases of infections. The noteworthy decrease in LOS implies an increase in admissions and in the turnover indicator of the hospital, which has a positive impact on the hospital management as well as on costs.

Lean management for improving hospital waiting times-Case study of a Vietnamese public/general hospital emergency department

INTRODUCTION

Emergency departments (EDs) at public hospitals in Vietnam typically face problems with overcrowding, as well as being populated by a wide variety of illnesses, resulting in increasing dissatisfaction from patients. To alleviate these problems, we used the increasingly popular value-stream mapping (VSM) and lean strategy approaches to (1) evaluate the current patient flow in EDs; (2) identify and eliminate the non-valued-added components; and (3) modify the existing process in order to improve waiting times.

METHODS

Data from a total of 742 patients who presented at the ED of 108 Military Central Hospital in Hanoi, Vietnam, were collected. A VSM was developed where improvement possibilities were identified and attempts to eliminate non-value-added activities were made. A range of issues that were considered as a resource waste were highlighted, which led to a re-design process focusing on prioritizing blood tests and ultrasound procedures. On the administrative side, various measures were considered, including streamlining communication with medical departments, using QR codes for healthcare insurance payments, and efficient management of X-ray and CT scan online results.

RESULTS

By implementing a lean approach, the following reductions in delay and waiting time were incurred: (1) pre-operative test results (for patients requiring medical procedures/operations) by 33.3% (from 134.4 to 89.4 min); (2) vascular interventions by 10.4% (from 54.6 to 48.9 min); and (3) admission to other hospital departments by 49.5% (from 118.3 to 59.8 min). Additionally, prior to the implementation of the lean strategy approach, only 22.9% of patients or their proxies (family members or friends), who responded to the survey, expressed satisfaction with the ED services. This percentage increased to 76.5% following the curtailment of non-value-added activities. Through statistical inferential test analyses, it can be confidently concluded that applying lean strategy and tools can improve patient flow in public/general hospital EDs and achieve better staff coordination within the various clinical and administrative hospital departments. To the authors' knowledge, such analysis in a Vietnamese hospital's ED context has not been previously undertaken.

Development of supply chain value stream map for government-supported drug distribution system

Purpose

The requirement of high-quality government-supported healthcare services has necessitated the significance of recognizing new management practices to enhance patient satisfaction. Hence, the purpose of this study is to address the patient's enhanced custom needs through the implementation of supply chain value stream mapping (SCVSM) in government-supported drug distribution system (DDS) for enhanced patient's satisfaction.

Design/methodology/approach

This study elucidates the role of one popular emerging management technique (i.e. SCVSM) in the healthcare sector by an investigative case study. The DDS in Rajasthan (India) was selected for this study. The data for this analysis were gathered in three ways (i.e. direct observation, documentary analysis and semi-structured interviews).

Findings

The outcome of this current study reveals that it is possible to apply the tool (SCVSM) to investigate the wastes in DDS to deliver the medicines at right time, right quantity and right quality. The application of SCVSM concluded that the various Kaizens (areas needed to improve) in lead time; transportation and routing should be adopted. The study further implemented kaizen on the current SCVSM and developed future SCVSM.

Research limitations/implications

Although various stages and functions exist in the healthcare supply chain, the current study is focused on the distribution system of drugs. The proposed approach provides a platform for both researchers and academicians to understand the existing DDS and to implement the SCVSM approach in the healthcare environment. The results show that the proposed SCVSM model is able to identify some operational bottlenecks and wastes which interfere in DDS.

Originality/value

It was observed that limited literature related to lean implementation on DDS and implementation of SCVSM on the healthcare environment in general and government-supported or public in specific are available. The current study on the application of SCVSM in DDS is unique in nature and will definitely add value to the existing literature of the application of value stream mapping (VSM) on the healthcare supply chain management field.

A Systematic Review on Lean Applications' in Emergency Departments

This article presents the state of the art of Lean principles applied in Emergency Departments through a systematic literature review. Our article extends previous work found in the literature to respond to the following questions: (i) What research problems in emergency departments can Lean principles help overcome? (ii) What Lean approaches and tools are used most often in this environment? (iii) What are the results and benefits obtained by these practices? and (iv) What research opportunities appear as gaps in the current state of the art on the subject? A six-step systematic review was performed following the guidance of the PRISMA method. The review analysis identified six main research problems where Lean was applied in Emergency Departments: (i) High Waiting Time and High Length of Hospital Stay; (ii) Health Safety; (iii) Process redesign; (iv) Management and Lessons Learned; (v) High Patient Flow; (vi) Cost Analysis. The six research problems’ main approaches identified were Lean Thinking, Multidisciplinary, Statistics, and Six Sigma. The leading Lean tools and methodologies were VSM, Teamwork, DMAIC, and Kaizen. The main benefits of applying Lean Principles were (a) reductions in waiting time, costs, length of hospital stay, patient flow, and procedure times; and (b) improvements in patient satisfaction, efficiency, productivity, standardization, relationships, safety, quality, and cost savings. Multidisciplinary integration of managers and work teams often yields good results. Finally, this study identifies knowledge gaps and new opportunities to study Lean best practices in healthcare organizations.

Evaluation of System Modelling Techniques for Waste Identification in Lean Healthcare Applications

Purpose

Waste identification plays a vital role in lean healthcare applications. While the value stream map (VSM) is among the most commonly used tools for waste identification, it may be limited to visualize the behaviour of dynamic and complex healthcare systems. To address this limitation, system modelling techniques (SMTs) can be used to provide a comprehensive picture of various system-wide wastes. However, there is a lack of evidence in the current literature about the potential contribution of SMTs for waste identification in healthcare processes.

Methods

This study evaluates the usability and utility of six types of SMTs along with the VSM. For the evaluation, interview-based questionnaires were conducted with twelve stakeholders from the outpatient clinic at the Heart and Vascular Institute at Cleveland Clinic Abu Dhabi.

Results

VSM was found to be the most useful diagram in waste identification in general. However, some SMTs that represent the system behaviour outperformed the VSM in identifying particular waste types, e.g., communication diagram in identifying over-processing waste and flow diagram in identifying transportation waste.

Conclusion

As behavioural SMTs and VSM have unique strengths in identifying particular waste types, the use of multiple diagrams is recommended for a comprehensive waste identification in lean. However, limited resources and time, as well as limited experience of stakeholders with SMTs, may still present obstacles for their potential contribution in lean healthcare applications.

Line managers and employees use of lean task boards in Norwegian municipal healthcare sector: a tool for action learning?

PURPOSE

This study aims to analyse the line managers and employees' use of lean task boards over time in Norwegian municipalities using action learning theory. The research question was the following: what kind of action learning processes do the line managers and employees' use of the lean task board promote in municipalities' healthcare units?

DESIGN/METHODOLOGY/APPROACH

This qualitative case study data from a Norwegian municipality involved analyses of 750 internal self-recorded logs from task board sessions from 6 different units and 25 semi-structured interviews of managers and employees.

FINDINGS

The task board works for line managers to make employees responsible for forwarding ideas, solutions and implementation of new actions. The use of the task boards contributes to systemising work through establishing new routines and improving orderliness at work. The line managers used the task boards as a project management system to track progress in the purchasing of diverse equipment and initiatives to improve professionalism and their units' facilities. The study explains the learning challenges for managers using the lean task board, as the method promotes finding experience-based solutions that do not involve critical reflection and use of theory.

PRACTICAL IMPLICATIONS

The lean task board is well-suited for managers to promote learning processes that counteract chaos in local healthcare organisations. However, the task board has limitations as a method for improving services amongst healthcare units and for solving difficult problems.

ORIGINALITY/VALUE

The study contributes to understanding how action learning theory can be applied to the analysis of the results of lean task board sessions.

Learning by doing: an undergraduate lean A3 project in a Kuwaiti bank

Purpose

This case study shows how methods of lean philosophy can be successfully taught to undergraduate students and applied to improving a real-world loan process. Students were instructed to use newly acquired classroom skills to analyse and improve a bank loan process in Kuwait.

Design/methodology/approach

This study involved an initial gemba walk through the bank. A case study format with direct observation and semi-structured interviews was adopted by 27 undergraduate students to identify waste, analyse the loan process and develop an efficiency plan.

Findings

The results revealed that undergraduate students could quickly learn basic lean principles and techniques and utilize them in a real-world situation to significantly improve a bank loan process. Areas of waste included over-production, over-processing, defects in procedure, under-utilized skills, wasted motions and poor time management. Suggested corrective measures were expected to reduce loan processing time by 30%.

Practical implications

Increasing costs and competition in the business environment make efficiency improvements imperative, and it was shown that students can play a major role in applying lean principles to a bank loan process while gaining knowledge and skills highly valued in industry. Universities have the opportunity to create a valuable learning experience for undergraduate students in applying classroom skills to solving a real-life problem.

Originality/value

This is the first study of a novel classroom technique for teaching undergraduate students to apply lean techniques in a Kuwaiti bank.

Fast track surgery for knee replacement surgery: a lean six sigma approach

Purpose

The reduction of costs has a more and more relevant role in the healthcare context, therefore, a large effort is done by health providers to this aim, for example, by reducing the length of hospital stay (LOS) of patients undergoing surgery. Fast track surgery fits perfectly this issue and was applied to patients undergoing knee replacement surgery due to Osteoarthritis, one of the most common diseases of aged population. The paper aims to discuss these issues.

Design/methodology/approach

Lean six sigma was applied to analyze the implementation of fast track surgery through the define, measure, analyze, improve, control roadmap, used as a typical problem-solving approach. It is characterized by five operational phases, which make possible the achievement of fixed goals through a rigorous process of defining, measuring, analyzing, improving and controlling business problems.

Findings

The corrective action, consisting in the application of fast track surgery, improved both effectiveness and efficiency of the process of care. The average length of hospital stay (LOS) was reduced from 8.34 to 6.68 days (–19.9 percent) and its standard deviation from 2.41 to 1.99 days (–17.1 percent). The statistical significance of this decrease was verified by means of proper tests. Moreover, some variables influencing the LOS were identified.

Research limitations/implications

The follow up and the satisfaction of patients were not analyzed and could be a future development of this study.

Practical implications

Patients will experience a faster recovery while the hospital will benefit from a rise of available beds. The effect is a general improvement of hospital management.

Originality/value

The introduction of fast track surgery for patients undergoing knee replacement surgery made significantly reduce LOS and, consequently, costs’ with a money saving of more than 50,000 euro per year.

Lean management and operational performance in health care

Purpose

The purpose of this paper is to examine the impact of lean management (LM) on operational performance (OP) in the context of health care in Jordanian private hospitals. LM is measured using four bundles: total quality management (TQM), human resource management (HRM), just-in-time system (JIT) and total productive maintenance (TPM). The study also investigates the effects of OP dimensions on hospitals’ business performance (BP).

Design/methodology/approach

The study is based on survey data collected from 260 respondents from 25 private hospitals in Jordan. Validity and reliability analyses were performed using SPSS and Amos, and the study hypotheses were tested using structural equation modeling.

Findings

The study found that the TQM bundle affects quality performance positively, but does not affect efficiency and accessibility performances, while the HRM bundle positively affects all OP dimensions. Furthermore, the JIT bundle positively contributes to both efficiency and accessibility performances, while the TPM bundle positively influences quality and accessibility performances. Moreover, the results have demonstrated that OP dimensions of quality and accessibility significantly and positively affect hospitals’ BP.

Originality/value

This study is one of the first to adapt the four lean bundles popularized in the manufacturing sector and apply them in a health-care context. It examines the effects of the four lean bundles on hospitals’ OP in terms of efficiency, quality and accessibility. In addition, the study demonstrates the role of OP dimensions in improving private hospitals’ BP.

An exploratory study into the use of Lean Six Sigma to reduce medication errors in the Norwegian public healthcare context

PURPOSE

Medication errors are a significant cause of injury in Norwegian hospitals. The purpose of this study is to explore how Lean Six Sigma (LSS) has been used in the Norwegian public health-care context to reduce medication errors.

DESIGN/METHODOLOGY/APPROACH

A mixed method approach was used to gather data from participants working in the four regions served by the Norway health authorities. A survey questionnaire was distributed to 38 health-care practitioners and semi-structured interviews were conducted with 12 health-care practitioners.

FINDINGS

The study finds that the implementation of LSS in the Norwegian public health-care context is still in its infancy. This is amidst several challenges faced by Norwegian hospitals such as the lack of top-management support, lack of LSS training and coaching and a lack of awareness around the benefits of LSS in health care.

RESEARCH LIMITATIONS/IMPLICATIONS

Because of the large geographical area, it was difficult to reach participants from all health regions in Norway. However, the study managed to assess the current status of LSS implementation through the participants' perspectives. This is a fruitful area for future research whereby an action research methodology could be used.

ORIGINALITY/VALUE

To the best of the authors' knowledge, this is the first empirical study into the use of LSS methodology in reducing medication errors. In addition, this study is valuable for health-care practitioners and professionals as a guideline to achieve the optimal benefit of LSS implementation to reduce medication errors.

Lean bundles in health care: a scoping review

PURPOSE

The purpose of this paper is to review original research on lean management (LM) in health care to identify potential research gaps and present recommendations for future research. The paper also discusses the current state of implementing LM practices in health care. In addition, it presents and highlights "lean bundles" imported from manufacturing, namely, total quality management (TQM), human resource management, just-in-time and total productive maintenance, as a potential implementation strategy of LM in hospitals to optimize overall health care performance.

DESIGN/METHODOLOGY/APPROACH

The scoping review was conducted based on the guidelines specified by Arksey and O'Malley (2005). Relevant included studies were retrieved by searching various electronic databases. The PRISMA guidelines were applied to identify and select eligible studies.

FINDINGS

The majority of previous studies used selected practices to measure LM in health care. In most cases, these practices reflected a narrow and biased view of LM. Lean bundles which comprehensively view LM and reflect all its aspects have rarely been discussed in the health care literature. Evidence about the contribution of lean bundles to hospital performance needs to be addressed in future studies.

PRACTICAL IMPLICATIONS

This paper demonstrates the implementation of the four lean bundles in hospitals. It argues that, instead of adopting one dimension or selected practices of LM, hospitals viewing LM as a comprehensive multi-dimensional approach through the adoption of the four lean bundles are expected to maximize their performances.

ORIGINALITY/VALUE

This is one of the first works to comprehensively review and discuss lean bundles in the context of health care. It argues that the adoption of the four lean bundles by hospitals will enable them to yield the maximum LM performance benefits. In addition, a proposed survey questionnaire based on the literature review is provided to assist researchers in conducting future empirical studies.

Lean implementation in healthcare supply chain: a scoping review

PURPOSE

The purpose of this paper is to identify the lean production (LP) practices applied in healthcare supply chain and the existing barriers related to their implementation.

DESIGN/METHODOLOGY/APPROACH

To achieve that, a scoping review was carried out in order to consolidate the main practices and barriers, and also to evidence research gaps and directions according to different theoretical lenses.

FINDINGS

The findings show that there is a consensus on the potential of LP practices implementation in healthcare supply chain, but most studies still report such implementation restricted to specific unit or value stream within a hospital.

ORIGINALITY/VALUE

Healthcare organizations are under constant pressure to reduce costs and wastes, while improving services and patient safety. Further, its supply chain usually presents great opportunities for improvement, both in terms of cost reduction and quality of care increase. In this sense, the adaptation of LP practices and principles has been widely accepted in healthcare. However, studies show that most implementations fall far short from their goals because they are done in a fragmented way, and not from a system-wide perspective.

V, R. R. Critical success factors of TQM, Six Sigma, Lean and Lean Six Sigma

Purpose

The purpose of this paper is to review the existing literature on the critical success factors (CSFs) of various continuous improvement (CI) like total quality management (TQM), Lean, Six Sigma and Lean Six Sigma (LSS), and perform a content analysis (CA) leading to an agenda for future research.

Design/methodology/approach

CA is based on literature review of 41 papers published in peer-reviewed scholarly journals. A four-stage methodology is used by the authors, with Stage 1 featuring relevant material collection; Stage 2 presenting a descriptive analysis; Stage 3 outlining the category selection; and Stage 4 featuring the material evaluation using clustering and Pareto analysis.

Findings

The CA revealed various research implications and directions for the future. The number of studies in the literature regarding CSF assessment is found to be far from substantial while compared to CI implementation. Assessment methodologies developed have been ranging from qualitative to quantitative models. Key gaps were identified and directions for CSF assessment are proposed which requires further validation.

Research limitations/implications

Only articles that appeared in peer-reviewed journals were analyzed; conference papers, reports, manuals and white papers from practice were excluded. Another limitation of the paper would be the scope of CA limited to four CI constructs – TQM, Lean, Six Sigma and LSS. Research implications indicate that the future studies in this domain would be intensive toward analyzing the vital CSFs for enterprise organizational excellence and not merely process excellence.

Practical implications

This review study can serve as a resource for both researchers and practitioners to understand the importance of CSFs and positioning CSFs for the successful implementation of CI programs.

Originality/value

The CA on the existing literature on CSFs for CI presents a unique, systematic effort to identify an agenda for future research. This study is the apparently the first of its kind on CSF assessment.

Lean healthcare: scale, scope and sustainability

Purpose

Lean healthcare is highlighted in the literature as an approach to quality improvement and operational efficiency. The purpose of this paper is to study how Lean healthcare has been implemented by analyzing empirical outcomes.

Design/methodology/approach

The authors used a literature review as the primary research method, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses process. Peer-reviewed journals were analyzed – searching for Lean healthcare implementation, tools used, wastes addressed, outcomes and sustainability.

Findings

Evidence suggests that Lean can improve healthcare operational effectiveness. However, empirical studies show implementation is still highly localized with small successes. Most transformations are focused on implementing one or two Lean tools that primarily target patient waiting times and there is minimal evidence about sustainability. Establishing clear definitions for healthcare-related Lean terminology may improve practice, especially episodic care and service quality.

Originality/value

This work provides a Lean healthcare case review. The research makes a significant contribution to Lean healthcare by increasing understanding (scale, scope and sustainability). From a theory building perspective, the authors suggest that barriers to adoption include a common healthcare-specific Lean terminology, and a need to expand implementation beyond small successes. This understanding will help identify key areas for further research in Lean healthcare management.

Quality measurement of Indian commercial hospitals – using a SERVQUAL framework

Purpose

The purpose of this paper is to understand and compare the level of patient’s expectations of healthcare services and their perceived performance. The paper also provides insights into the specific service factors and quality of hospital services which are required to meet the needs of Indian patients.

Design/methodology/approach

A total of 210 exit interviews were conducted using a structured questionnaire addressing the probable factors of quality related to healthcare services in a five-point Likert scale. The survey was conducted among the patients recently discharged and about to be discharged from private hospitals of Delhi and NC. A set of questionnaires is administered to collect responses on expected and perceived service qualities.

Findings

The paper reviews and discusses the importance of service quality for Indian patients using the SERVQUAL gap model as the measure of service quality. The results gave an overview of the perspectives of Indian patients on the quality of service in private hospitals. Patients indicated best satisfaction in some dimensions of services, namely, the tangible dimension of “hospitals provide ample parking spaces,” empathy dimension of “Doctors are never too busy to respond to my request”, assurance dimension of “I can depend on Doctor/Nurse,” and in the responsiveness dimension of “employees always communicate truly” on hospital matters.

Research limitations/implications

The first limitation is in the scope of sample, that is research findings are limited to Delhi. The second limitation is that the research should have been done in two parts, that is by contacting the patient before they take the services and after the service encounter. Third limitation – for a better understanding, the analysis should have been performed on the gap between the patient’s perception and the perception of the medical service provider about the customer’s perception.

Practical implications

This research would be beneficial to healthcare organizations to do their best to achieve greater patient satisfaction. The findings of the paper that, for all dimensions, the patient’s perception is always higher than the expectation suggests that in the Indian healthcare segment, there is a need of dissemination of information regarding the most modern medical facilities.

Originality/value

This current research is concluded with the suitability of a model that can be used to find the levels of patient satisfaction for healthcare services. The present study is based on primary data and offers a systematic procedure that could form the cornerstone for providing further insights into the conceptual and empirical comprehension of patients perceived service quality and its constituents. The current emergency medicine patient’s service dilemmas are a complex interaction of patients and physician factors specifically targeting efficiency and patient satisfaction. The awareness of these issues particular to the emergency patient can help to maximize efficiency, minimize subsequent medico-legal risk and improve patient care if a tailored management plan is formulated.

TQM and lean strategy deployment in Italian hospitals

Purpose This paper aims to contribute to the debate concerning total quality management (TQM)-Lean strategy in public healthcare by analyzing the deployment path for implementation, the possible benefits that can be achieved and the encountered pitfalls. Design/methodology/approach Three case studies are drawn from three large Italian hospitals with more than 500 beds each and structured with many departments. The hospitals are located in Tuscany, Italy. These three hospitals have embraced TQM and Lean, starting from strategic objectives and their deployment. At the same time, they have also implemented many TQM-Lean tools. The case studies are based on interviews held with four managers in each of these three public hospitals. Findings Results from the interviews show that there is a specific deployment path for TQM-Lean implementation. The hospitals have also achieved benefits linked to patient satisfaction and improved organizational performances. Problems related to organizational and cultural issues, such as senior managers' commitment, staff management, manufacturing culture and tools adaptation, could affect the benefits. Research limitations/implications The research has been carried out in just three Italian public hospitals. Hence, similar investigations could be managed in other countries. Researchers could also use a larger sample and investigate these issues by means of quantitative inquiry. Practical implications Practitioners could try to apply the deployment path revealed by these case studies in other public and private hospitals. Originality/value The results of this research show that there is a specific, new deployment path for implementing TQM-Lean strategy in some public hospitals.

Based on the outcomes of the lean tools that are applied in various work areas, the best combinations of lean tools are identified and several key considerations are discussed.

Practical implications

This paper shows that a combined set of lean tools such as line balancing, standardized work and standardized layout can be applied to improve productivity in the printing operations, which is identifiable with a mix of processes that are both labor intensive and equipment flexible.

Originality/value

The paper fills the literature gap on the use of specific lean tools: line balancing, standardized work and standardized layout in the printing industry. The findings from this research can be applied to other assembly systems that are similar to the printing industry.

Prioritizing lean management practices in public and private hospitals

Purpose - The purpose of this paper is to prioritize 21 healthcare wastes in public and private hospitals of United Arab Emirates (UAE). Design/methodology/approach - Seven healthcare wastes linked with lean management are further decomposed in to sub-criteria and to deal with this complexity of multi criteria decision-making process, analytical hierarchical process (AHP) method is used in this research. Findings - AHP framework for this study resulted in a ranking of 21 healthcare wastes in public and private hospitals of UAE. It has been found that management in private healthcare systems of UAE is putting more emphasis on the inventory waste. On the other hand, over processing waste has got highest weight in public hospitals of UAE. Research limitations/implications - The future directions of this research would be to apply a lean set of tools for the value stream optimization of the prioritized key improvement areas. Practical implications - This is a contribution to the continuing research into lean management, giving practitioners and designers a practical way for measuring and implementing lean practices across health organizations. Originality/value - The contribution of this research, through successive stages of data collection, measurement analysis and refinement, is a set of reliable and valid framework that can be subsequently used in conceptualization, prioritization of the waste reduction strategies in healthcare management.

V. Lean services: a systematic review

Purpose

The purpose of this paper is to highlight the importance of Lean methodology through an exhaustive literature review, and its implications and application in the service industry right from its initiation in 1990s till date.

Design/methodology/approach

The paper summarises the evolution of Lean in services and has systematically classified the reviewed literature in four dimensions, namely time, publisher, region and content. Further under “time” dimension, the literature is classified into Pre-Lean era, Lean awareness era, Lean Exploration era and Lean implementation era. Under the “content” dimension, the categories include theoretical foundation, frameworks/models and application/case studies.

Findings

The analysis inferred; Lean is gaining roads in services, though the research is still at nascent stage. Lean is applicable in services though transfer of Lean manufacturing principles to services has certain limitations because of the characteristics of services. The need is to focus on process difference between services and manufacturing. Respect for people and employment engagement is critical to Lean in service. The authors identified the necessity to standardise the Lean service definition, principles, and tools and to develop guidelines for structured implementation in service industry.

Research limitations/implications

Though multiple databases have been taken-up but that does not assume that the literature presented in this paper is by any means comprehensive. Development of a standard model/framework for Lean services is critical for future research. Rigorous industry-specific studies, specifically in developing nations are another area for future research. Future studies could analyse the impact of join applications and possible links between Lean service and other approaches like TQM, Six Sigma, etc., with an aim of process improvement.

Practical implications

This paper would serve as a resource for Lean practitioners as well as researchers as a fundamental platform, contributing to Lean body of knowledge.

Social implications

Service industry has special significance to the society in large. Many services including governments, public interest services, non-profit organisations, healthcare, banking, consulting, etc., has a significant share across markets. Lean being a proven methodology for successful process improvements has to be looked at from a services perspective. This paper helps in such interest.

Originality/value

Publications reviewing the adoption of Lean in services is scarce in literature. This paper serves as an excellent resource for research on the subject and will facilitate academicians and practitioners to objectively understand Lean in service sector.

Utilizing lean tools to improve value and reduce outpatient wait times in an Indian hospital

Purpose

– This paper aims to demonstrate how lean tools were applied to some unique issues of providing healthcare in a developing country where many patients face challenges not found in developed countries. The challenges provide insight into how lean tools can be utilized to provide similar results across the world.

Design/methodology/approach

– This paper is based on a qualitative case study carried out by a master’s student implementing lean at a hospital in India.

Findings

– This paper finds that lean tools such as value-stream mapping and root cause analysis can lead to dramatic reductions in waste and improvements in productivity. The problems of the majority of patients paying for their own healthcare and lacking transportation created scheduling problems that required patients to receive their diagnosis and pay for treatment within a single day. Many additional wastes were identified that were significantly impacting the hospital’s ability to provide care. As a result of this project, average outpatient wait times were reduced from 1 hour to 15 minutes along with a significant increase in labor productivity.

Practical implications

– The results demonstrate how lean tools can increase value to the patients. It also provides are framework that can be utilized for healthcare providers in developed and developing countries to analyze their value streams to reduce waste.

Originality/value

– This paper is one of the first to address the unique issues of implementing lean to a healthcare setting in a developing country.
