New Pattern | Example |
---|---|
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] |
