PURPOSE: To describe the colonization rate and types of organism in the isolates of patients admitted to a continuing care hospital (CCH).
METHODS: Retrospective, single center, observational cohort study of CCH patients admitted between May 2007 to Dec 2007. Subjects were included in the study if a tracheostomy was present on admission. A database was constructed with information from electronic records, microbiology and radiology results.
RESULTS: Seventy patients were admitted within the time period, 41.4% were female. Mini-BALs were obtained in 61 patients (87.1%). 36/61 patients (59.0%) with mini-BALs were positive for organisms. Of the 36 patients with a positive mini-BAL, 13 patients (36.1%) grew Pseudomonas species, 7 (19.4%) grew MRSA, 3 (8.3%) grew MSSA, 3 (8.3%) grew Enterobacteriae, 2 (5.5%) grew E. Coli. 10 patients (27.7%) grew organisms other than those listed. Sixty-six of 70 patients presented with infiltrates on chest radiograph on admission, the remaining 4 patients with negative infiltrates on chest radiograph had negative cultures on their mini-BALs.
CONCLUSION: Colonization rate was 59.0% in our study. Most common organism by mini-BAL was Pseudomonas species, with MRSA as the second most common organism found. Patients without infiltrates on chest radiograph were mini-BAL culture negative for organisms.
CLINICAL IMPLICATIONS: Patients with tracheostomy have a high rate of colonization with potential multi-drug resistance organism.
