The use of Lean tools to reduce inpatient waiting time in a Thai public hospital: an action research study

PURPOSE

The aims of this paper are to illustrate the use of Lean tools to reduce inpatient waiting time and to evaluate critical success factors of Lean implementation in an inpatient pharmacy in a Thai public hospital.

DESIGN/METHODOLOGY/APPROACH

This study was carried out through action research methodology by following four key phases: identification of problems; planning action; taking action; and evaluation. In the "taking action" phase, Lean tools, including value stream mapping and 5S were implemented to improve dispensing process in an inpatient pharmacy. In the "evaluation phase", the critical success factors of Lean implementation in an inpatient pharmacy were evaluated by the participants.

FINDINGS

Lean methodology was successfully implemented to reduce the waiting time associated with a three days dose distribution system. As a result of Lean application, the average process time reduced from 8.81 to 7.2 min and the standard deviation reduced from 5.49 to 4.45 min. Moreover, the support of middle management and the leadership were the key success factors of Lean implementation in an inpatient pharmacy.

PRACTICAL IMPLICATIONS

Hospitals can improve the dispensing process by using Lean tools which are easy to apply and use. This study is appropriate for hospital managers looking for changes in pharmacy services or other departments.

ORIGINALITY/VALUE

This is the first study that has applied Lean tools to improve the dispensing process in an inpatient pharmacy in Thai hospitals. This study offers important insights into the critical success factors of Lean employment in the inpatient pharmacy.

Lean Six Sigma implementation and sustainability roadmap for reducing medication errors in hospitals

Purpose

The purpose of this study is to propose a Lean Six Sigma (LSS) roadmap to guide healthcare practitioners in the implementation of LSS along with a customized LSS tool kit for reducing medication errors.

Design/methodology/approach

The authors initially critically reviewed several frameworks/roadmaps of Lean, Six Sigma and LSS which have been proposed in healthcare sector from the existing literature. This review has led to an understanding of key characteristics, limitations and reasons behind the development of such frameworks/roadmaps. A conceptual roadmap was developed and then validated by a number of LSS experts and a healthcare practitioner. Based on the previous studies and taking LSS experts’ opinions into account, a revised roadmap for reducing medication is presented.

Findings

The roadmap for LSS in reducing medication errors is developed. This roadmap includes three phases: Phase 1 cultural readiness for LSS employment in reducing medication errors; Phase 2 preparation, initialization and implementation; and Phase 3 sustainability.

Research limitations/implications

The roadmap has been tested with only a handful of practitioners of LSS. Moreover, only two case studies have been carried out in a Thai hospital setting which followed the roadmap. In order to improve the validity of research, more case studies need to be executed and more people should be used for testing the roadmap with varied cultures.

Originality/value

This is the first attempt in the development of a LSS roadmap that healthcare practitioners can follow to reduce medication errors using LSS methodology and sustaining LSS in their organizations.

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.

Can Lean Six Sigma be used to reduce medication errors in the health-care sector?

Purpose The purpose of this paper is to present the implementation of Lean Six Sigma (LSS) to reduce medication errors, by using four case examples. The paper will also suggest appropriate Lean and Sigma tools to improve the medication process. Design/methodology/approach The authors critically analyze four case examples that used LSS projects, to demonstrate the approach, benefits, success factors and lessons learnt. Findings LSS is a powerful process improvement methodology that could be applied by health-care sectors to reduce medication errors, increase patient safety and reduce operational costs. Common Lean and Six Sigma tools play a significant role in improving and sustaining the medication process. Practical implications It is necessary for the project team to select the most appropriate LSS tools to address medication process problems. Adoption of a LSS roadmap could help health-care organizations in the successful implementation of LSS. Originality/value The paper is valuable for health-care professionals seeking to reduce errors in the medication process or other processes that need to be improved.
