ABSTRACT
OBJECTIVE: We describe the efficacy of enhanced infection control measures, including those recommended in the Centers for Disease Control and Prevention's 2012 carbapenem-resistant Enterobacteriaceae (CRE) toolkit, to control concurrent outbreaks of carbapenemase-producing Enterobacteriaceae (CPE) and extensively drug-resistant Acinetobacter baumannii (XDR-AB). DESIGN: Before-after intervention study. SETTING: Fifteen-bed surgical trauma intensive care unit (ICU). METHODS: We investigated the impact of enhanced infection control measures in response to clusters of CPE and XDR-AB infections in an ICU from April 2009 to March 2010. Polymerase chain reaction was used to detect the presence of blaKPC and resistance plasmids in CRE. Pulsed-field gel electrophoresis was performed to assess XDR-AB clonality. Enhanced infection-control measures were implemented in response to ongoing transmission of CPE and a new outbreak of XDR-AB. Efficacy was evaluated by comparing the incidence rate (IR) of CPE and XDR-AB before and after the implementation of these measures. RESULTS: The IR of CPE for the 12 months before the implementation of enhanced measures was 7.77 cases per 1,000 patient-days, whereas the IR of XDR-AB for the 3 months before implementation was 6.79 cases per 1,000 patient-days. All examined CPE shared endemic blaKPC resistance plasmids, and 6 of the 7 XDR-AB isolates were clonal. Following institution of enhanced infection control measures, the CPE IR decreased to 1.22 cases per 1,000 patient-days (P = .001), and no more cases of XDR-AB were identified. CONCLUSIONS: Use of infection control measures described in the Centers for Disease Control and Prevention's 2012 CRE toolkit was associated with a reduction in the IR of CPE and an interruption in XDR-AB transmission.

BACKGROUND: The outcomes of patients with biochemically confirmed hyperparathyroidism but a negative Tc-99 Sestamibi scan are unclear. We examined the outcomes and quality of life of patients having surgery and those who had medical therapy. METHODS: Patients having a diagnosis of hyperparathyroidism with confirmed elevated calcium and parathormone levels, yet negative sestamibi scans were identified. The RAND SF-36 Health Survey was administered via mail to these patients. The patient's charts were then reviewed to verify treatments and to determine outcomes. RESULTS: Ninety-five patients fitting the criteria were identified. Twenty patients completed all aspects of the study. Ten of the respondents had undergone parathyroidectomy, and 10 had not. The surgical patients scored more favorably in all 8 of the measured parameters than patients treated medically. The differences in 3 domains, physical functioning, pain, and social functioning, were statistically significant. CONCLUSIONS: Our findings suggest that surgical therapy confers a better quality of life and is superior to medical therapy in the treatment of primary hyperparathyroidism, even in patients having a negative sestamibi scan.
