Primary Outcome Measures :
  1. This research will help to identify risk factors for resistance to an antibiotic that is commonly used in the empiric treatment of critically ill patients. [ Time Frame: 2 years ]

Biospecimen Retention:   Samples Without DNA
No genetic testing will be performed on any of the samples being obtained. The biologic samples will be under the control of the principal investigator of this research project. To protect confidentiality, all personal identifiers (i.e., name, social security number, and birth date) will be removed (de-identified) and replaced with a specific code number. The information linking these code numbers to the corresponding subjects' identities will be kept in a separate, secure location. The investigators on this study will keep the samples indefinitely. If a subject withdraws and provides the request in writing, samples collected and not already processed will be destroyed. All samples will be kept in the investigator's laboratory located in Scaife Hall, Room 812, 3550 Terrace Street.

Criteria

Inclusion Criteria:

  • Clinical information is collected by chart review of "case" and "control" patients.
  • A "case A" patient is defined as follows: One or more clinical cultures are positive for an ESBL producing bacteria and the organism is piperacillin/tazobactam resistant.
  • A "case B" patient is defined as follows: One or more clinical cultures are positive for an ESBL producing bacteria and the organism is piperacillin/tazobactam susceptible.
  • Additionally, 1 control patient in the hospital at the same time as the case patients will be randomly selected for each case and are not in either case group.

Exclusion Criteria:

  • Patients < 18 years of age
