Patient experience in a surgical assessment unit following a closed-loop audit using a Kaizen Lean system

Background The Acute Surgical Assessment Unit (ASAU) in University Hospital Limerick (UHL) has provided a solution to overcrowding and long waiting times since centralization of emergency services to UHL. Recognising the importance of its evolving role, the ASAU in UHL has recently undergone a major revamp to ease the pressure in the overcrowded emergency department (ED). This included a new purpose state-of-the-art-built unit and equipment, improved staffing levels and use of a Kaizen Lean system to identify key area of delays and inefficiency with subsequent implementation of suggestions derived after Kaizen Lean. Patient satisfaction reporting was analysed in the older building and subsequently in the new site post Kaizen Lean to complete a closed-loop audit. The aim of the study was to examine patient satisfaction response rates with the ASAU prior to and following Kaizen Lean implementation and transfer to a new purpose-built unit. Methods The survey comprised of two phases. In phase 1, 100 questionnaires were distributed to patients in ASAU (older building, pre-Kaizen Lean). In phase 2, the survey was repeated (100 patients) after Kaizen Lean implementation and transfer to the new state-of-the-art unit. Questionnaire design was based on WHO strategy on responsiveness measurement guidelines and was tailored to a population of surgical patients. Results were analysed using IBM SPSS, version 21 and Excel 2013. Results Two hundred questionnaires were analysed. Implementation of suggestions derived post Kaizen Lean translated into improved resource usage with reduced waiting time to be seen by nurses and doctors. Patients had better awareness about their treatment plan and planned next steps in the management. Satisfaction across different domains, perceptions of privacy and overall treatment were also improved. Conclusions A Kaizen Lean approach improved the transition of an ASAU to a new purpose-built unit and further improved overall patient satisfaction with services of the ASAU.
