Los Angeles County health officials advised doctors to give up on testing patients in the hope of containing the coronavirus outbreak, instructing them to test patients only if a positive result could change how they would be treated.
The guidance, sent by the Los
Angeles County Department of Public Health to doctors on Thursday, was
prompted by a crush of patients and shortage of tests, and could make
it difficult to ever know precisely how many people in L.A. County
contracted the virus.
The department “is shifting from a strategy of case containment to slowing disease transmission and averting excess morbidity and mortality,” according to the letter. Doctors should test symptomatic patients only when “a diagnostic result will change clinical management or inform public health response.”
The guidance sets in writing what has been a reality all along. The shortage of tests nationwide has meant that many patients suspected of having COVID-19 have not had the diagnosis confirmed by a laboratory.
