Diagnosing patient waiting times in hospitals

Abstract: This seminar will discuss a new approach to diagnosing throughput time performance in hospitals. Reducing patient throughput times, in terms of length of stay and admission time, is an important objective for many hospitals. However, we claim that appropriate instruments to determine specific causes of delays are lacking. The instruments presented in this seminar elaborate on an approach to diagnosing the delays of customer orders in high-variety manufacturing environments. Quantitative patient progress data from hospital information systems is analysed by techniques based on input/output modelling. A time-phased representation is applied, since most patient flows will reveal dynamic patterns. Using this representation, we could point out how e.g. excessive waiting times in an emergency care unit resulted from an insufficient capacity response to increasing patient inflow rates at early stages of the day. The same approach has been studied for diagnosing waiting times in care pathways, surgery waiting times and times to provide lab results.

Speaker information

Martin Land,University of Groningen ,Martin Land is an Associate Professor of Operations Management at the University of Groningen in the Netherlands. He holds an MSc in Econometrics and Operations Research and a PhD in Management Sciences from the same university. He has recently been a visiting researcher in Lancaster (UK), Sao Carlos (Brazil) and Clemson (US). A large part of his research has focused on Production Planning and Control in Make-To-Order production environments and more particularly the concept of Workload Control, which has resulted in more than 25 international journal papers. Three of his most recent papers on Workload Control were published in POM. His attention has now moved to healthcare settings and he is involved in projects on patient waiting times and the performance impact of Lean in hospitals.
