- Target Recruitment
- 71
- The participant was treated with Minocin IV for a presumed or culture-confirmed gram-negative infection, as monotherapy or part of a broader regimen, for at least 48 hours.
- The participant treatment for gram-negative infection was initiated May 1, 2015, or later.
- The participant was at least 18 years old.
- This was the first course of Minocin IV administered to the participant within the study period for the treatment of gram-negative infection.
- At least 60 days has elapsed since the participant received the last dose of Minocin IV therapy for a presumed or confirmed gram-negative infection (prior to data entry into the electronic case report form, including step-down to oral therapy.
- The participant received Minocin IV as a part of a controlled clinical trial.
- The participant received Minocin IV as a part of a Medicines Company- or Rempex Company-sponsored pharmacoeconomic outcomes study.
- Pregnancy (in the participant's or participant's partner) occurred after the first dose of Minocin IV through hospital discharge.
- Female participants were pregnant or nursing at the time of enrollment.

Group Intervention Description Minocycline IV Minocycline IV Participants who received 2 doses over 48 hours if given once daily or 4 doses over 48 hours if given twice daily of minocycline intravenous (IV) as monotherapy, with or without transition to oral minocycline.
- Primary Outcome Measures
Name Time Method Number Of Participants With Each Gram-negative Bacterial Infection Being Treated With Minocycline IV Day 1 The types of primary infections refers to only presumed or documented gram-negative bacterial infections.
Duration Of Treatment With Minocycline IV Day 1 through end of infusion with minocycline The number of days of treatment with minocycline IV will be presented.
Proportion Of Participants With A Microbiologic Eradication Or Microbiologic Persistence Up to 30 days after minocycline infusion Microbiological assessments will be based on participant records between end of infusion to 30 days following the last dose of minocycline (includes minocycline IV plus oral minocycline). Microbiological categories will include only gram-negative pathogens believed to be related to the primary infection and are defined as:
* Eradication: Documentation of a negative bacterial culture from the same site as the initial positive baseline culture
* Presumed eradication: The absence of follow-up microbiological data/information in a participant with a clinical response of cure or improved
* Persistence: Bacterial growth from the same site as the initial positive baseline culture excluding colonization; also referred to as microbiologic failure.Infection-related Length Of Stay For Infections Being Treated With Minocycline IV Up to 30 days after minocycline IV infusion Data will be collected to include infection-related length of stay , which is defined as the difference between the day of initiation of antimicrobial administration for the primary infection and day of discontinuation, death, or discharge date, whichever is sooner. This may include minocycline IV or other empiric antimicrobial regimen.
Number Of Participants With A Microbiologic Response Up to 30 days after minocycline IV infusion The number of participants with a gram-negative pathogen for which minocycline IV is used for treatment of the primary infection site(s) and the number of participants with a gram-positive pathogen recovered from a secondary infection site or from a mixed culture also containing the targeted gram-negative pathogen will be presented.
Use Of Concomitant Antibiotics With Minocycline IV Day 1 through end of infusion with minocycline Concomitant antibiotics include those used between the first and last dose of minocycline IV. The number of participants and the type of antibiotic taken will be presented.
Proportion Of Participants With A Clinical Outcome Of Cure, Improved, Or Failure Up to 30 days after minocycline infusion Clinical assessments will be based on participant records between end of infusion to 30 days following the last dose of minocycline (includes minocycline IV plus oral minocycline). Clinical categories for assessment include:
* Cure: Clinical signs and symptoms are resolved and no additional antibiotic therapy is necessary for the treatment of the infection
* Improved: Partial resolution of clinical signs and symptoms and no additional antibiotic therapy is necessary for the treatment of the infection
* Failure: Inadequate resolution, or new or worsening clinical signs and symptoms, such that additional antibiotic therapy is necessary for treatment of the infection
* Non-evaluable: Unable to determine response because the participant record did not contain the necessary information to determine cure, improvement, or failure.
