As a patient, you bear the brunt of the chaos resulting from poor management of operations at healthcare delivery organizations. Patients suffer in the form of excessive delays and cancellations of scheduled appointments, inadequate access to services, long waiting times, and compromised quality of care when care is delayed and provided in inappropriate settings or with inadequate staffing levels. One common cause behind all of these problems is artificial variability in patient flow driven by inappropriate scheduling practices. The inappropriate scheduling of elective cases, and the mixing of resources for urgent and scheduled patients, causes an unnecessary and potentially dangerous competition for those resources.
