Methods: We reviewed all adult inpatients at NYPH with blood cultures positive for S. aureus from 7/25/14 to 12/28/14. For patients with multiple episodes of SAB within the study period, only the first episode was included. Inpatient and outpatient medical records were reviewed. Data were entered into a de-identified database. Statistical analysis was performed using IBM SPSS v20. Paired t-tests were used for continuous variables and Chi-square tests for categorical variables.
Results: Sixty-four episodes of S. aureus bacteremia were identified. Six were excluded because of age below 18, outpatient status, or recurrent bacteremia. Of the 58 remaining patients, 41 (71%) had an ID consult. 43/58 (74%) were on a medicine service, and 32 of these patients (74%) had an ID consult. MRSA bacteremia occurred in 22 patients and 19/22 (86%) had an ID consult; MSSA bacteremia occurred in 36 patients and 22/36 (61%) had an ID consult (p = 0.04). Echocardiograms were performed in 38/41 (93%) of the ID consult group vs 8/17 (41%) in the no-consult group (p<0.001). In-hospital mortality rate was 17% (7/41) in the ID consult group vs 41% (7/17) in the no-consult group (p=0.051). Of the 17 patients who did not receive a consult, one had a primary ID hospitalist attending and five received end-of-life palliative care measures; four of the latter group died in the hospital. In two patients who did not receive an ID consult, the primary team was not aware of the culture results.
Conclusion: Greater than two-thirds of inpatients with SAB had an ID consult, which is consistent with published data. ID consult was significantly associated with use of echocardiography. There was a trend toward lower mortality which may have been influenced by palliative care measures in the no-consult group. Targeted education toward primary services regarding the value of ID consultation in S. aureus bacteremia may improve patient outcomes.
