Table 5 Examples of patterns not covered by the workflow control-flow patterns

From: Leveraging workflow control patterns in the domain of clinical practice guidelines

New Pattern


Structured discriminator, named task

Patient should immediately receive oxygen and aspirin. An immediate electrocardiogram should be done and the physician called for as the patient is placed on a cardiac monitor. Intravenous access should be obtained and cardiac markers drawn. … In the critically ill patient whose vitals are compromised (i.e., cardiac arrest, tachyarrhythmias, severe bradycardia, shock or hypotension), the Advanced Cardiac Life Support guideline should be followed [NB: The critically ill patient is identified through the vital signs coming from the cardiac monitoring] [58]

Structured partial join, named tasks

Perform: CBC with diff; UA; Cultures—blood and urine; (Consider wait on LP); Stool for WBC and culture (if diarrhea); Chest radiograph (if respiratory signs) If all low risk clinical and laboratory criteria met (see Table 2) [NB: In urinalysis, <10 WBC/hpf; In CBC, WBC 5,000 to 15,000/mm3; etc.; cultures for blood, urine, and stool are taken, but care is continued without waiting for results] then consider outpatient management or admission for observation [57]
