Abstract
We focus on two of the many sources of uncertainty in healthcare operations, mix uncertainty – the variation in the complexity of care required by the patient mix, and volume uncertainty – the variation in the volume of care demanded by the patient population. Using an interdisciplinary perspective, we study the impact of mix and volume uncertainties on two important healthcare outcomes, length of stay and number of procedures, along with the mitigation impacts of the operational concepts of related focus and utilization levels. Based on large dataset of 830,853 patient discharges in 26 clinical departments across 731 hospitals in five U.S. Midwest states, our results indicate that mix and volume uncertainties each have a significant impact on patient care. We also find that related focus and department utilization levels have a mitigating effect on uncertainty in healthcare settings. Lastly, we find considerable heterogeneity in the effects of uncertainty across hospital types and departments. We discuss key research and managerial implications of our findings.
期刊介绍：
The Journal of Operations Management (JOM) is a leading academic publication dedicated to advancing the field of operations management (OM) through rigorous and original research. The journal's primary audience is the academic community, although it also values contributions that attract the interest of practitioners. However, it does not publish articles that are primarily aimed at practitioners, as academic relevance is a fundamental requirement.
JOM focuses on the management aspects of various types of operations, including manufacturing, service, and supply chain operations. The journal's scope is broad, covering both profit-oriented and non-profit organizations. The core criterion for publication is that the research question must be centered around operations management, rather than merely using operations as a context. For instance, a study on charismatic leadership in a manufacturing setting would only be within JOM's scope if it directly relates to the management of operations; the mere setting of the study is not enough.
Published papers in JOM are expected to address real-world operational questions and challenges. While not all research must be driven by practical concerns, there must be a credible link to practice that is considered from the outset of the research, not as an afterthought. Authors are cautioned against assuming that academic knowledge can be easily translated into practical applications without proper justification.
JOM's articles are abstracted and indexed by several prestigious databases and services, including Engineering Information, Inc.; Executive Sciences Institute; INSPEC; International Abstracts in Operations Research; Cambridge Scientific Abstracts; SciSearch/Science Citation Index; CompuMath Citation Index; Current Contents/Engineering, Computing & Technology; Information Access Company; and Social Sciences Citation Index. This ensures that the journal's research is widely accessible and recognized within the academic and professional communities.
