The JAMA Diagnostic Test Interpretation article titled “Interpreting SARS-CoV-2 Test Results,” published online on September 17, 2021, included an error in the Discussion that presented an incorrect positive predictive value for a SARS-CoV-2 test. The Discussion has been corrected and indicates that the positive predictive value of the test for the patient was 6.5%. (All other information in the Discussion was correct and is unchanged.)

In the Editorial titled “Vasopressin and Steroids as Adjunctive Treatment for In-Hospital Cardiac Arrest,” published online in the September 29, 2021, issue of JAMA, there was a factual error regarding the proportion of patients who received targeted temperature management in the VAM-IHCA trial. The sentence that read, “In the VAM-IHCA trial, all patients received targeted temperature management, although several differences existed between study groups during the postresuscitation period” should have read, “In the VAM-IHCA trial, the proportion of patients who received targeted temperature management was comparable in the intervention group (27%) and in the placebo group (26%), although several differences existed between study groups during the postresuscitation period.” This article was corrected online.

Cardiopulmonary arrest occurs in approximately 290 000 hospitalized patients annually in the United States, representing nearly 1% of all admissions and with survival estimated at 20%. To date, most research on cardiopulmonary arrest has focused on patients who experience cardiac arrest in the out-of-hospital setting with results extrapolated to those with cardiac arrest in hospitals. However, there are distinct differences in the treatment of patients who experience cardiac arrest in the hospital setting where disease processes, etiologies, and illness severity differ and medical response time is often shorter.
