Use of Lean Six Sigma methodology shows reduction of inpatient waiting time for peripherally inserted central catheter placement

Simulation and evaluation of increased imaging service capacity at the MRI department using reduced coil-setting times

The wait times for patients from their appointments to receiving magnetic resonance imaging (MRI) are usually long. To reduce this wait time, the present study proposed that service time wastage could be reduced by adjusting MRI examination scheduling by prioritizing patients who require examinations involving the same type of coil. This approach can reduce patient wait times and thereby maximize MRI departments' service times. To simulate an MRI department's action workflow, 2,447 MRI examination logs containing the deidentified information of patients and radiation technologists from the MRI department of a medical center were used, and a hybrid simulation model that combined discrete-event and agent-based simulations was developed. The experiment was conducted in two stages. In the first stage, the service time was increased by adjusting the examination schedule and thereby reducing the number of coil changes. In the second stage, the maximum number of additional patients that could be examined daily was determined. The average number of coil changes per day for the four MRI scanners of the aforementioned medical center was reduced by approximately 27. Thus, the MRI department gained 97.17 min/d, which enabled them to examine three additional patients per month. Consequently, the net monthly income of the hospital increased from US$17,067 to US$30,196, and the patient wait times for MRI examinations requiring the use of flexible torso and head, shoulder, 8-inch head, and torso MRI coils were shortened by 6 d and 23 h, 2 d and 15 h, 2 d and 9 h, and 16 h, respectively. Adjusting MRI examination scheduling by prioritizing patients that require the use of the same coil could reduce the coil-setting time, increase the daily number of patients who are examined, increase the net income of the MRI department, and shorten patient wait times for MRI examinations. Minimizing the operating times of specific examinations to maximize the number of services provided per day does not require additional personnel or resources. The results of the experimental simulations can be used as a reference by radiology department managers designing scheduling rules for examination appointments.

A balanced approach involving hard and soft factors for internalizing Lean Management and Six Sigma in hospitals

Purpose

This study examines the theoretical and empirical relationships between LM&SS, human resource management (HRM), climate for LM&SS and outcomes (employee well-being and performance) in hospitals. As part of this research, the authors examine the interplay between “hard” and “soft” practices for LM&SS and “soft” HR practices.

Design/methodology/approach

A cross-sectional, multisite survey study covering all internal service units at all eight Dutch university hospitals was conducted (42 units, N = 218 supervisors, N = 1,668 employees), and multivariate multilevel regression analyses were performed.

Findings

A systems approach involving “soft” LM&SS practices that are specifically HR-related has a positive effect (β is 0.46) on a climate for LM&SS. A climate for LM&SS is not related to perceived performance or employee health. It is, however, positively related to employee happiness and trusting relationships (both βs are 0.33). We did not find that a climate for LM&SS had a mediating effect.

Research limitations/implications

This study shows that a balanced approach involving both “hard” and “soft” factors is crucial to achieving the desired breadth and depth of LM&SS adoption at the macro, meso, and micro levels. The authors found that a climate for LM&SS positively affects employee well-being in hospitals.

Practical implications

In their attempt to create mutual gains for both their organization and their employees, hospitals that adopt LM&SS should foster a climate for LM&SS by embracing a balanced approach consisting of both “hard” and “soft” practices, thereby internalizing LM&SS at the macro, meso, and micro levels.

Originality/value

This is one of the first studies to examine in-depth the impact of “hard” and “soft” LM&SS on both employee well-being (subdivided into different components) and performance in healthcare, as well as the role of “soft” HRM in this relationship. Linking LM&SS, HRM and outcomes to a climate for LM&SS is relatively a new approach and has led to a deeper understanding of the mechanisms underpinning the internalization of LM&SS in healthcare.

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.

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.

A qualitative study of the adoption of Value Stream Mapping in breast cancer centers

PURPOSE

In order to design a patient-centered discharge process, the entire process is visualized in Value Stream Mapping. The duration of the process steps and waiting times are measured and presented. As a team, health professionals discuss problems and agree on suitable solutions.

METHODS

After applying Value Stream Mapping, we conducted eight interviews in 2018, four with physicians and four with breast care nurses. We used the Consolidated Framework for Implementation Research to develop the interview guide and to identify categories for content analysis. To identify the differences in attitude and experience between the occupational groups, we conducted a framework analysis.

RESULTS

Each team of health professionals developed action steps to optimize the discharge process. Obstacles became apparent in the implementation of these action steps. The lack of adequate staff and complex structures were identified as the main factors. These hierarchical structures also prevented a patient-centered discharge process independent of patient-centered care by health professionals. Self-efficacy varied more among breast care nurses than physicians. The group of physicians perceives standardization in the discharge process critically and therefore assumes limitations in transferring Value Stream Mapping to hospitals. The breast care nurses were open in their attitude. Financial incentives contribute to the acceptance of the method.

CONCLUSION

Value Stream Mapping is a simple way to uncover waste and develop applicable action steps. Since the implementation of the action steps was hindered by hierarchical problems and a lack of resources, management involvement and a hospital-wide approach could be beneficial.

Lean Healthcare Tools for Processes Evaluation: An Integrative Review

Several health services have used lean healthcare to seek continuous improvement of their processes. Therefore, it is important to investigate the evidence available in the literature about the most used lean tools in the health area to review processes and the main results achieved by the researchers. As an integrative literature review methodology was used, it was conducted in five databases, using the descriptor "quality improvement" and the keyword "Lean Healthcare". A total of 33 complete articles were selected for analysis. The most recurrent tools were: define, measure, analyze, improve and control (DMAIC); value stream map (VSM); suppliers, inputs, process, outputs, customers analysis (SIPOC), Ishikawa Diagram and 5S. Through the analysis of waste, different interventions were implemented and the main results achieved were reduction in times (processing, waiting, cycle and total), costs, workload and increase in the number of calls. The findings enabled the identification of the main lean tools used in the health area to achieve better results. In particular, we highlight recent studies that have explored the lean six sigma healthcare approach. The results, in addition to contributing to the literature, will also assist managers in choosing the best tool to achieve continuous improvement in hospitals and other health services.
