Using Lean Six Sigma in a Private Hospital Setting to Reduce Trauma Orthopedic Patient Waiting Times and Associated Administrative and Consultant Caseload.

In Ireland, the extent of outpatient orthopedic waiting lists results in long waiting times for patients, delays in processing referrals, and variation in the consultant caseload. At the study site, the Define, Measure, Analyze, Improve, and Control (DMAIC) Lean Six Sigma framework was applied to evaluate sources of Non-Value-Added (NVA) activity in the process of registering and triaging patients referred to the trauma orthopedic service from the Emergency Department. A pre- (October-December 2021)/post- (April-August 2022) intervention design was employed, utilizing Gemba, Process Mapping, and the TIMWOODS tool. Embracing a person-centered approach, stakeholder Voice of Customer feedback was sought at each stage of the improvement process. Following data collection and analysis, a co-designed pilot intervention (March 2022) was implemented, consisting of a new triage template, dedicated trauma clinic slots, a consultant triage roster, and a new option to refer directly to physiotherapy services. This resulted in the total wait time of patients for review being reduced by 34%, a 51% reduction in the process steps required for registering, and an increase in orthopedic consultant clinic capacity of 22%. The reduction in NVA activities in the process and the increase in management options for triaging consultants have delivered a more efficient trauma and orthopedic pathway.

Using a Combined Lean and Person-Centred Approach to Support the Resumption of Routine Hospital Activity following the First Wave of COVID-19.

The unexpected advent of the COVID-19 pandemic led to a sudden disruption of routine medical care, with a subsequent reorganization of hospital structures and of care. Case studies are becoming available in the literature referring to the logistical difficulties involved in a hospital resuming normal activity following the first COVID-19 lockdown period. This paper details the experience of a study site, a private hospital in Dublin, Ireland, in the redesign of service delivery in compliance with new COVID-19 prevention regulations to facilitate the resumption of routine hospital activity following the first wave of COVID-19. The aim was to resume routine activity and optimize patient activity, whilst remaining compliant with COVID-19 guidelines. We employed a pre-/post-intervention design using Lean methodology and utilised a rapid improvement event (RIE) approach underpinned by person-centred principles. This was a system-wide improvement including all hospital staff, facilitated by a specific project team including the chief operation officer, allied therapy manager (encompassing health and social care professionals), infection prevention and control team, head of surgical services, clinical nurse managers, patient services manager and the head of procurement. Following our intervention, hospital services resumed successfully, with the initial service resumption meeting the organizational target of a 75% bed occupancy rate, while the number of resumed surgeries exceeded the target by 13%. Our outpatient visits recovered to exceed the attendance numbers pre-COVID-19 in 2019 by 10%. In addition, patient satisfaction improved from 93% to 95%, and importantly, we had no in-hospital patient COVID-19 transmission in the study period of July to December 2020.

Developing New Methods for Person-Centred Approaches to Adjudicate Context-Mechanism-Outcome Configurations in Realist Evaluation.

Realist evaluation provides a general method of evaluating the application of interventions including policy, legislation, projects, and new processes in social settings such as law enforcement, healthcare and education. Realist evaluation focuses on what about interventions works, for whom, and in what circumstances, and there is a growing body of work using realist evaluation to analyse interventions in healthcare organizations, including those using Lean Six Sigma improvement methodologies. Whilst realist evaluation facilitates the analysis of interventions using both qualitative and quantitative research, there is little guidance given on methods of data collection and analysis. The purpose of this study is to address this lack of guidance through detailing the use of innovative person-centred methods of data collection and analysis in a realist evaluation that enabled us to understand the contribution of Lean Six Sigma to person-centred care and cultures. This use of person-centred principles in the adjudication of identified program theories has informed novel methods of collecting and analysing data in realist evaluation that facilitate a person-centred approach to working with research participants and a way of making the implicit explicit when adjudicating program theory.

The Use of Lean Six Sigma Methodology in the Reduction of Patient Length of Stay Following Anterior Cruciate Ligament Reconstruction Surgery.

Background: The purpose of this study was to reduce the length of stay of anterior cruciate ligament reconstruction patients within a private hospital in Ireland, reducing any non-value-added activity in the patient pathway, with the goal of increasing patient flow, bed capacity, and revenue generation within the hospital system, while maintaining patient satisfaction. Methods: We used a pre-/post-intervention design and Lean Six Sigma methods and tools to assess and improve the current process. Results: A reduction in inpatient length of stay by 57%, and a reduction in identified non-value-added activity by 88%, resulted in a new day-case surgery pathway for anterior cruciate ligament reconstruction patients. The pathway evidenced no re-admissions and demonstrated patient satisfaction. Conclusion: Six months post-project commencement, we had successfully achieved our goals of reducing our anterior cruciate ligament reconstruction patient's length of stay. This study contributes to the growing body of published evidence which shows that adopting a Lean Six Sigma approach can be successfully employed to optimise care and surgical pathways in healthcare.

A Case Study of a Whole System Approach to Improvement in an Acute Hospital Setting.

Changes in healthcare tend to be project-based with whole system change, which acknowledges the interconnectedness of socio-technical factors, not the norm. This paper attempts to address the question of whole system change posed by the special issue and brings together other research presented in this special issue. A case study approach was adopted to understand the deployment of a whole system change in the acute hospital setting along four dimensions of a socio-technical systems framework: culture, system functioning, action, and sense-making. The case study demonstrates evidence of whole system improvement. The approach to change was co-designed by staff and management, projects involving staff from all specialities and levels of seniority were linked to each other and to the strategic objectives of the organisation, and learnings from first-generation projects have been passed to second and third-generation process improvements. The socio-technical systems framework was used retrospectively to assess the system change but could also be used prospectively to help healthcare organisations develop approaches to whole system improvement.

Using Lean Six Sigma to Redesign the Supply Chain to the Operating Room Department of a Private Hospital to Reduce Associated Costs and Release Nursing Time to Care.

Continuity of the supply chain is an integral element in the safe and timely delivery of health services. Lean Six Sigma (LSS), a continuous improvement approach, aims to drive efficiencies and standardisation in processes, and while well established in the manufacturing and supply chain industries, also has relevance in healthcare supply chain management. This study outlines the application of LSS tools and techniques within the supply chain of an Operating Room (OR) setting in a private hospital in Dublin, Ireland. A pre-/post-intervention design was employed following the Define, Measure, Analyse, Improve, Control (DMAIC) framework and applying LSS methodology to redesign the current process for stock management both within the OR storage area and within a pilot OR suite, through collaborative, inclusive, and participatory engagement with staff. A set of improvements were implemented to standardise and streamline the stock management in both areas. The main outcomes from the improvements implemented were an overall reduction in the value of stock held within the operating theatre by 17.7%, a reduction in the value of stock going out of date by 91.7%, and a reduction in the time spent by clinical staff preparing stock required for procedures by 45%, all demonstrating the effectiveness of LSS in healthcare supply chain management.

The Use of Lean Six Sigma for Improving Availability of and Access to Emergency Department Data to Facilitate Patient Flow.

The aim of this study was to redesign an emergency department [ED] data management system to improve the availability of, and access to, data to facilitate patient flow. A pre-/post-intervention design was employed using Lean Six Sigma methodology with a focus on the voice of the customer, Gemba, and 5S to identify areas for improvement in ED data management processes and to inform solutions for improved ED patient flow processes. A multidisciplinary ED team includes medical consultants and registrars, nurses, patient service staff, radiology staff, as well as information technology and hospital management staff. Lean Six Sigma [LSS] diagnostic tools identified areas for improvement in the current process for data availability and access. A set of improvements were implemented to redesign the pathway for data collection in the ED to improve data availability and access. We achieved a reduction in the time taken to access ED patient flow data from a mean of 9 min per patient pre-intervention to immediate post-intervention. This enabled faster decision-making by the ED team related to patient assessment and treatment and informed improvements in patient flow. Optimizing patient flow through a hospital's ED is a complex task involving collaboration and participation from multiple disciplines. Through the use of LSS methodology, we improved the availability of, and fast access to, accurate, current information regarding ED patient flow. This allows ED and hospital management teams to identify and rapidly respond to actions impacting patient flow.

Lean Six Sigma Redesign of a Process for Healthcare Mandatory Education in Basic Life Support-A Pilot Study.

Healthcare staff are required to undertake mandatory training programs to ensure they maintain key clinical competencies. This study was conducted in a private hospital in Ireland, where the processes for accessing mandatory training were found to be highly complex and non-user friendly, resulting in missed training opportunities, specific training license expiration, and underutilized training slots which resulted in lost time for both the trainers and trainees. A pilot study was undertaken to review the process for accessing mandatory training with a focus on the mandatory training program of Basic Life Support (BLS). This was chosen due to its importance in patient resuscitation and its requirement in the hospital achieving Joint Commission International (JCI) accreditation. A pre- and post-team-based intervention design was used with Lean Six Sigma (LSS) methodology employed to redesign the process of booking, scheduling, and delivery of BLS training leading to staff individual BLS certification for a period of two years. The redesign of the BLS training program resulted in a new blended delivery method, and the initiation of a pilot project led to a 50% increase in the volume of BLS classes and a time saving of 154 h 30 min for staff and 48 h 14 min for BLS instructors. The success of the BLS process access pilot has functioned as a platform for the redesign of other mandatory education programs and will be of interest to hospitals with mandatory training requirements that are already facing healthcare challenges and demands on staff time.

A Rapid Realist Review of Quality Care Process Metrics Implementation in Nursing and Midwifery Practice.

Quality measurement initiatives promote quality improvement in healthcare but can be challenging to implement effectively. This paper presents a Rapid Realist Review (RRR) of published literature on Quality Care-Process Metrics (QCP-M) implementation in nursing and midwifery practice. An RRR informed by RAMESES II standards was conducted as an efficient means to synthesize evidence using an expert panel. The review involved research question development, quality appraisal, data extraction, and evidence synthesis. Six program theories summarised below identify the key characteristics that promote positive outcomes in QCP-M implementation. Program Theory 1: Focuses on the evidence base and accessibility of the QCP-M and their ease of use by nurses and midwives working in busy and complex care environments. Program Theory 2: Examines the influence of external factors on QCP-M implementation. Program Theory 3: Relates to existing cultures and systems within clinical sites. Program Theory 4: Relates to nurses' and midwives' knowledge and beliefs. Program Theory 5: Builds on the staff theme of Programme Theory four, extending the culture of organizational learning, and highlights the meaningful engagement of nurses and midwives in the implementation process as a key characteristic of success. Program Theory 6: Relates to patient needs. The results provide nursing and midwifery policymakers and professionals with evidence-based program theory that can be translated into action-orientated strategies to help guide successful QCP-M implementation.

Redesigning the Process for Scheduling Elective Orthopaedic Surgery: A Combined Lean Six Sigma and Person-Centred Approach.

The Health Service Executive Ireland model of care for elective surgery supports the delivery of elective surgical care in achieving both process and clinical outcomes. This project was conducted in the Orthopaedic Department. Following an outpatient consultation with an orthopaedic surgeon, patients who required surgical intervention were scheduled for their intervention by the administrative team. Prior to commencing this project, the average time from patient consultation to being scheduled for surgery on the hospital system was 62 h/2.58 days. A pre- and post-team-based intervention design employing Lean Six Sigma methodology was applied to redesign the process for scheduling elective orthopaedic surgery. The project was informed by collaborative, inclusive, and participatory stakeholder engagement. The goal was to streamline the scheduling process for elective orthopaedic surgery, with a target that 90% of surgeries are scheduled "right first time" within 48 h/two working days of the outpatient consultant appointment. The main outcome measures showed that 100% of orthopaedic surgeries were scheduled successfully within 2 days of outpatient appointment. Duplication in work between patient services and scheduling teams was eliminated and facilitated a reduction in unnecessary staff workload. This project highlights the importance of collaborative interdisciplinary stakeholder engagement in the redesigning of processes to achieve sustainable outcomes, and the findings have informed further improvements across the hospital's surgical scheduling system.

Releasing Operating Room Nursing Time to Care through the Reduction of Surgical Case Preparation Time: A Lean Six Sigma Pilot Study.

Healthcare systems internationally are working under increasing demand to use finite resources with greater efficiency. The drive for efficiency utilises process improvement methodologies such as Lean Six Sigma. This study outlines a pilot Lean Six Sigma intervention designed to release nursing time to care within a peri-operative environment; this was achieved by collaborating with stakeholders to redesign the process for laparoscopic hernia surgical case preparation (set up) material. Across 128 laparoscopic hernia surgical cases, the pilot resulted in a 55% decrease in overall nursing time spent in gathering and preparing materials for laparoscopic hernia surgical cases, with a corresponding reduction in packaging waste. The major impact of releasing nursing time to care within busy Operating Room environments enabled nurses to focus on continuing to deliver high-quality care to their patients and reduce pressure expressed by the Operating Room nurses. The results have led to an ongoing review of other surgical procedures preparation to further release nursing time and will be of interest to perioperative teams internationally.

Operation Note Transformation: The Application of Lean Six Sigma to Improve the Process of Documenting the Operation Note in a Private Hospital Setting.

Clinical documentation is a key safety and quality risk, particularly at transitions of care where there is a higher risk of information being miscommunicated or lost. A surgical operation note (ON) is an essential medicolegal document to ensure continuity of patient care between the surgical operating team and other colleagues, which should be completed immediately following surgery. Incomplete operating surgeon documentation of the ON, in a legible and timely manner, impacts the quality of information available to nurses to deliver post-operative care. In the project site, a private hospital in Dublin, Ireland, the accuracy of completion of the ON across all surgical specialties was 20%. This project sought to improve the accuracy, legibility, and completeness of the ON in the Operating Room. A multidisciplinary team of staff utilised the Lean Six Sigma (LSS) methodology, specifically the Define/Measure/Analyse/Design/Verify (DMADV) framework, to design a new digital process application for documenting the ON. Post-introduction of the new design, 100% of the ONs were completed digitally with a corresponding cost saving of EUR 10,000 annually. The time to complete the ON was reduced by 30% due to the designed digital platform and mandatory fields, ensuring 100% of the document is legible. As a result, this project significantly improved the quality and timely production of the ON within a digital solution. The success of the newly designed ON process demonstrates the effectiveness of the DMADV in establishing a co-designed, value-adding process for post-operative surgical notes.

A Realist Inquiry to Identify the Contribution of Lean Six Sigma to Person-Centred Care and Cultures.

A lack of fidelity to Lean Six Sigma's (LSS) philosophical roots can create division between person-centred approaches to transforming care experiences and services, and system wide quality improvement methods focused solely on efficiency and clinical outcomes. There is little research into, and a poor understanding of, the mechanisms and processes through which LSS education influences healthcare staffs' person-centred practice. This realist inquiry asks 'whether, to what extent and in what ways, LSS in healthcare contributes to person-centred care and cultures'. Realist review identified three potential Context, Mechanism, Outcome configurations (CMOcs) explaining how LSS influenced practice, relating to staff, patients, and organisational influences. Realist evaluation was used to explore the CMOc relating to staff, showing how they interacted with a LSS education Programme (the intervention) with CMOc adjudication by the research team and study participants to determine whether, to what extent, and in what ways it influenced person-centred cultures. Three more focused CMOcs emerged from the adjudication of the CMOc relating to staff, and these were aligned to previously identified synergies and divergences between participants' LSS practice and person-centred cultures. This enabled us to understand the contribution of LSS to person-centred care and cultures that contribute to the evidence base on the study of quality improvement beyond intervention effectiveness alone.

Quality care process metrics (QCP-Ms) in nursing and midwifery care processes: a rapid realist review (RRR) protocol.

Background: In 2018, the Office of the Nursing and Midwifery Services Director (ONMSD) completed phase one of work which culminated in the development and launch of seven research reports with defined suites of quality care process metrics (QC-Ms) and respective indicators for the practice areas - acute care, midwifery, children's, public health nursing, older persons, mental health and intellectual disability nursing in Ireland. This paper presents a rapid realist review protocol that will systematically review the literature that examines QC-M in practice; what worked, or did not work for whom, in what contexts, to what extent, how and why? Methods : The review will explore if there are benefits of using the QC-Ms and what are the contexts in which these mechanisms are triggered. The essence of this rapid realist review is to ascertain how a change in context generates a particular mechanism that produces specific outcomes. A number of steps will occur including locating existing theories on implementation of quality care metrics, searching the evidence, selecting relevant documents, data extraction, validation of findings, synthesising and refining programme theory. This strategy may help to describe potential consequences resulting from changes in context and their interactions with mechanisms. Initial theories will be refined throughout the process by the local reference panel, comprised of eight key intervention stakeholders, knowledge users such as healthcare professionals and an expert panel. Ethical approval is not required for this rapid realist review. Conclusion: It is anticipated that the final programme theory will help to explain how QC-Ms work in practice; for whom, why and in what circumstances. Findings of this review could help to give insights into realism as a framework and how nursing and midwifery QC-Ms have been implemented previously.

Using Lean Six Sigma to improve rates of day of surgery admission in a national thoracic surgery department.

OBJECTIVE: The aim of this study is to improve rates of day of surgery admission (DOSA) for all suitable elective thoracic surgery patients. DESIGN: Lean Six Sigma (LSS) methods were used to enable improvements to both the operational process and the organizational working of the department over a period of 19 months. SETTING: A national thoracic surgery department in a large teaching hospital in Ireland. PARTICIPANTS: Thoracic surgery staff, patients and quality improvement staff at the hospital. INTERVENTION(S): LSS methods were employed to identify and remove the non-value-add in the patient's journey and achieve higher levels of DOSA. A pre-surgery checklist and Thoracic Planning Meeting were introduced to support a multidisciplinary approach to enhanced recovery after surgery (ERAS), reduce rework, improve list efficiency and optimize bed management. MAIN OUTCOME MEASURE(S): To achieve DOSA for all suitable elective thoracic surgery patients in line with the National Key Performance Indicator of 75%. A secondary outcome would be to further decrease overall length of stay by 1 day. RESULTS: Over a 19 month period, DOSA has increased from 10 to 75%. Duplication of preoperative tests reduced from 83 to <2%. Staff and patient surveys show increased satisfaction and improved understanding of ERAS. CONCLUSIONS: Using LSS methods to improve both operational process efficiency and organizational clinical processes led to the successful achievement of increasing rates of DOSA in line with national targets.

Streamlining an existing hip fracture patient pathway in an acute tertiary adult Irish hospital to improve patient experience and outcomes.

OBJECTIVE: To improve access for hip fracture patients to surgery within 48 h of presentation to the Emergency Department, and to increase the number of patients receiving pre-operative orthogeriatric review, through streamlining an existing hip fracture patient pathway. DESIGN: A pre-post design involving a multi-disciplinary team use of the Define, Measure, Analyse, Improve and Control framework integral to Lean Six Sigma (LSS) methodology, to assess and adapt the existing hip fracture pathway from presentation to Emergency Department to the initiation of surgery. SETTING: A 600-bed teaching hospital in Ireland. PARTICIPANTS: Nursing, medical, administrative and physiotherapy staff working across Emergency Medicine, Orthogeriatrics and Orthopaedic Specialities and Project management. INTERVENTIONS: LSS methodology was used to redesign an existing pathway, improving patient access to ortho-geriatrician assessment, pain relief and surgery in line with the Irish Hip Fracture Data Base Key performance indicators. MAIN OUTCOME MEASURES: Access to pain relief, access to surgery and volume of patients receiving ortho-geriatric assessment. RESULTS: The percentage of patients undergoing surgery within 48 h of presentation to Emergency Department increased from 55% to 79% at 3 months, and to 85% at 6 months. Improvements were also achieved in the secondary performance metrics relevant to quality of patient care. All care pathway changes were cost neutral. CONCLUSIONS: Hip fracture surgery within 48 h of presentation to hospital is a recognized standard of hip fracture care associated with decreased length of stay and decreased mortality. With respect to this performance metric, this intervention has contributed to improved patient outcomes.

Reducing risk of development or exacerbation of nutritional deficits by optimizing patient access to mealtime assistance.

OBJECTIVE: Optimize patient access to mealtime assistance, decrease missed meal incidence, risk of malnutrition, reduce food waste and staff rework. DESIGN: Lean Six Sigma methodology informed a pre/post intervention design. SETTING: 31 bed ward including Specialist Geriatric services and Acute Stroke Unit within an Irish University teaching hospital. PARTICIPANTS: Clinical and non-clinical staff including catering, nursing, speech and language therapy, dietetics and nutrition; patients, relatives. INTERVENTIONS: An interdisciplinary team used the structured Define/Measure/Analyse/Improve/Control (DMAIC) framework to introduce visual aids and materials to improve the access of patients to assistance at mealtimes. MAIN OUTCOME MEASURES: Pre and post outcomes measures were taken for the number and cost of uneaten meals, rework for staff, staff and patient satisfaction, patient outcomes. RESULTS: Following a 1-month pilot of a co-designed process for ensuring access to assistance at mealtimes, average wasted meals due to staff not being available to assist patients requiring mealtime assistance went from 3 per day to 0 corresponding to an average reduction of 0.43 kg per participating patient in food waste per day. Patients receiving assistance did not require additional oral therapeutic nutritional supplements, evidenced no new incidences of aspiration pneumonia or swallowing difficulties and were discharged without requirement for ongoing Dietetics and Nutrition support. Following a 6 month Control period comprising repeated PDCA cycles, the initiative was incrementally introduced to a further 10 wards/units, with positive feedback from patients and staff alike. CONCLUSION: The co-designed new process highlights the importance of staff and patient collaboration, inclusion and participation in designing quality improvement projects.

Developing a university-accredited Lean Six Sigma curriculum to overcome system blindness.

This paper discusses the development of a Lean Six Sigma (LSS) postgraduate education programme that has enabled the delivery of over 90 quality improvement projects led by its graduates across 50 healthcare organizations in Ireland. A key success factor in embedding and sustaining LSS in these organizations was the accreditation by a major, national, research-intensive university of the LSS education programme from which the students graduated. To ensure the programme's approval by the university it was necessary to contextualize LSS within established conceptual frameworks. This helped counter misconceptions that what was proposed was technical training in tools and techniques to provide quick fixes for routine healthcare process issues. Two related conceptual frameworks were selected to frame the curriculum: Senge's Fifth Discipline and Deming's System of Profound Knowledge. This paper focuses on how a central element of both frameworks, systems thinking or appreciation for a system, was enacted in the curriculum using Oshry's work on system blindness. Showing how systems thinking was conceptualized in the curriculum established the legitimacy and credibility of the programme within academia. This led to the approval of the first university-accredited graduate programme in LSS for healthcare in Ireland.
