Utilization of Lean & Six Sigma quality initiatives in Indian healthcare sector

PURPOSE

The purpose of this paper is to investigate the utilization of Lean & Six Sigma quality initiatives in healthcare sector in India.

METHODOLOGY

The survey questionnaires were sent to 454 hospitals through registered postal in all the states of India. The survey questionnaire was designed to assess different quality initiatives; currently implemented in Indian hospitals, factors align with organization's objectives, reasons for not implementing Lean & Six Sigma and contribution of Lean & Six Sigma projects in healthcare improvement projects etc. A separate section in the questionnaire provides the feedback on implementation of Lean & Six Sigma in various hospitals. The relationships between Lean & Six Sigma and healthcare performance have also been established in this paper.

FINDINGS

It is found that 15 Nos. of hospitals have implemented the Lean tools while 14 Nos. have implemented the Six Sigma tools out of 109 collected responses. This shows the utilization of Lean & Six Sigma in Indian healthcare sector. The 'Lack of knowledge' and 'Availability of resources' are the major reasons for not implementing Lean & Six Sigma. It is also observed that 22% running projects were related to Lean & Six Sigma out of various improvement projects running in various hospitals.

ORIGINALITY

There is lack of evidences of similar studies that determines the utilization of Lean & Six Sigma in Indian healthcare sector at the national level. This paper will provide important breakthrough to academicians and healthcare practitioners, who are involved in Lean & Six Sigma research.

SOCIAL IMPLICATIONS

The present study will create awareness among healthcare practitioners across India for utilization of quality tools that will provide direct benefits to the society.

A Novel Conceptual Approach to Lean: Value, Psychological Conditions for Engagement With Work and Perceived Organisational Support in Hospital Care

Background

Lean thinking (LT) has emerged as a promising approach for reducing waste and improving efficiency. However, its applicability to and effectiveness within healthcare, particularly within hospital-based care, remains clouded by uncertainty. This paper attempts to answer the question ‘how lean thinking can best be applied to hospital-based care’.

Methods

Narrative review and conceptual synthesis

Results

We first review the principles of LT and how some of them are challenging to apply within hospital-based care. We then highlight that lean is an approach that was always meant as a combination of technical expertise and a focus on people—supported by a suite of human resource management supportive practices. We proceed to introduce evidence stemming from the literature studies on perceived organizational support and the psychological conditions for successful staff engagement with their work (namely, psychological meaningfulness, availability and safety as experienced by staff) and review how they may apply to hospital-based health workers. We finally advance a set of hypotheses regarding how different facets of value in a hospital care pathway may be correlated and these relationships mediated/moderated by perceived organizational support and the psychological conditions for engagement with work.

Conclusion

We conclude with a discussion of the limitations of our work and the aspiration that the conceptual analysis we have offered is a useful and actionable framework for hospital management to explore how best to support their staff—in a manner that ultimately achieves better quality and patient experience of care.

Process improvement approaches in emergency departments: a review of the current knowledge

Purpose

The healthcare system has been under pressure to provide timely and quality healthcare. The influx of patients in the emergency departments (EDs) is testing the capacity of the system to its limit. In order to increase EDs' capacity and performance, healthcare managers and practitioners are adopting process improvement (PI) approaches in their operations. Thus, this study aims to identify the main PI approaches implemented in EDs, as well as the benefits and barriers to implement these approaches.

Design/methodology/approach

The study is based on a rigorous systematic literature review of 115 papers. Furthermore, under the lens of thematic analysis, the authors present the descriptive and prescriptive findings.

Findings

The descriptive analysis found copious information related to PI approaches implemented in EDs, such as main PIs used in EDs, type of methodological procedures applied, as well as a set of barriers and benefits. Aiming to provide an in-depth analysis and prescriptive results, the authors carried out a thematic analysis that found underlying barriers (e.g. organisational, technical and behavioural) and benefits (e.g. for patients, the organisation and processes) of PI implementation in EDs.

Originality/value

The authors contribute to knowledge by providing a comprehensive review of the main PI methodologies applied in EDs, underscoring the most prominent ones. This study goes beyond descriptive studies that identify lists of barriers and benefits, and instead the authors categorize prescriptive elements that influence these barriers and benefits. Finally, this study raises discussions about the behavioural influence of patients and medical staff on the implementation of PI approaches.

Methodological Approaches to Support Process Improvement in Emergency Departments: A Systematic Review

The most commonly used techniques for addressing each Emergency Department (ED) problem (overcrowding, prolonged waiting time, extended length of stay, excessive patient flow time, and high left-without-being-seen (LWBS) rates) were specified to provide healthcare managers and researchers with a useful framework for effectively solving these operational deficiencies. Finally, we identified the existing research tendencies and highlighted opportunities for future work. We implemented the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) methodology to undertake a review including scholarly articles published between April 1993 and October 2019. The selected papers were categorized considering the leading ED problems and publication year. Two hundred and three (203) papers distributed in 120 journals were found to meet the inclusion criteria. Furthermore, computer simulation and lean manufacturing were concluded to be the most prominent approaches for addressing the leading operational problems in EDs. In future interventions, ED administrators and researchers are widely advised to combine Operations Research (OR) methods, quality-based techniques, and data-driven approaches for upgrading the performance of EDs. On a different tack, more interventions are required for tackling overcrowding and high left-without-being-seen rates.

Applying lean management to reduce radiology turnaround times for emergency department

Given the high impact of emergency department (ED) on the quality of care delivered by an hospital, and the many challenges it is facing (eg, overcrowding, excessive waiting time, cost containment, and increasing demand from patients), innovative managerial approaches should be adopted in order to develop safer and more efficient healthcare in this setting. The current study focuses on an application of lean thinking to reduce radiology turnaround times for ED, with the final aim to highlight the key factors enabling the adoption of lean thinking in this context. A research framework has been developed in the literature to analyse lean projects in healthcare and it has been adapted to study the case selected in an Italian hospital. In particular, organizational aspects, phases, and activities of the applied methodology, tools and procedures, and the achieved outcomes have been analysed. The study reports how radiology turnaround times for ED can be significantly reduced applying lean management principles and techniques. The achieved results contribute not only to comply with the regulation, but also to enhance the quality of care delivered to the patient; moreover, staff communication, involvement, and process awareness are favoured by the realization of similar projects promoting the diffusion of a lean culture.

Improvement of emergency department patient flow using lean thinking

Objective

To apply lean thinking in triage acuity level-3 patients in order to improve emergency department (ED) throughtput and waiting time.

Design

A prospective interventional study.

Setting

An ED of a tertiary care hospital.

Participants

Triage acuity level-3 patients.

Intervention(s)

To apply lean techniques such as value stream mapping, workplace organization, reduction of wastes and standardization by the frontline staff.

Main Outcome Measure(s)

Two periods were compared: (i) pre-lean: April-September, 2015; and (ii) post-lean: April-September, 2016. Variables included: median process time (time from beginning of nurse preparation to the end of nurse finalization after doctor disposition) of both discharged and transferred to observation patients; median length of stay; median waiting time; left without being seen, 72-h revisit and mortality rates, and daily number of visits. There was no additional staff or bed after lean implementation.

Results

Despite an increment in the daily number of visits (+8.3%, P < 0.001), significant reductions in process time of discharged (182 vs 160 min, P < 0.001) and transferred to observation (186 vs 176 min, P < 0.001) patients, in length of stay (389 vs 329 min, P < 0.001), and in waiting time (71 vs 48 min, P < 0.001) were achieved after lean implementation. No significant differences were registered in left without being seen rate (5.23% vs 4.95%), 72-h revisit rate (3.41% vs 3.93%), and mortality rate (0.23% vs 0.15%).

Conclusion

Lean thinking is a methodology that can improve triage acuity level-3 patient flow in the ED, resulting in better throughput along with reduced waiting time.

Nurses' Perspectives on Lean Redesigns to Patient Flow and Inpatient Discharge Process Efficiency

As hospitals around the world increasingly face pressure to improve efficiency, "Lean" process improvement has become a popular approach to improving patient flow. In this article, we examine nurses' perspectives on the implementation of Lean redesigns to the inpatient discharge process. We found that nurses experienced competing demands and tensions related to their time and professional roles and responsibilities as a result of Lean. Four main themes included (a) addressing the needs of individual patients, while still maintaining overall patient flow; (b) meeting discharge efficiency targets while also achieving high patient satisfaction scores; (c) "wasting time" to save time; and (d) the "real" work of providing clinical care versus the "Lean" work of process improvement. Our findings highlight the importance of soliciting hospital nurses' perspectives when implementing Lean process improvements to improve efficiency and patient flow.

Lean Thinking in emergency departments: a critical review

Emergency departments (EDs) face problems with crowding, delays, cost containment, and patient safety. To address these and other problems, EDs increasingly implement an approach called Lean thinking. This study critically reviewed 18 articles describing the implementation of Lean in 15 EDs in the United States, Australia, and Canada. An analytic framework based on human factors engineering and occupational research generated 6 core questions about the effects of Lean on ED work structures and processes, patient care, and employees, as well as the factors on which Lean's success is contingent. The review revealed numerous ED process changes, often involving separate patient streams, accompanied by structural changes such as new technologies, communication systems, staffing changes, and the reorganization of physical space. Patient care usually improved after implementation of Lean, with many EDs reporting decreases in length of stay, waiting times, and proportion of patients leaving the ED without being seen. Few null or negative patient care effects were reported, and studies typically did not report patient quality or safety outcomes beyond patient satisfaction. The effects of Lean on employees were rarely discussed or measured systematically, but there were some indications of positive effects on employees and organizational culture. Success factors included employee involvement, management support, and preparedness for change. Despite some methodological, practical, and theoretic concerns, Lean appears to offer significant improvement opportunities. Many questions remain about Lean's effects on patient health and employees and how Lean can be best implemented in health care.
