Brief summary

To assess the efficacy and safety of Tygacil in the usual German hospital setting. The main goals are: to assess the efficacy of Tygacil under usual care conditions (cure rate); to assess the main side effects observed in daily medical practice (Safety of Tygacil); to determine whether patients are optimally dosed with Tygacil (according to the label) and the proportion of patients receiving a monotherapy versus combination therapy; to observe the potential resistance development against Tygacil in Germany; to determine which antibiotic agents are chosen for a combination therapy with Tygacil; to determine to which antibiotic substance non-responders to Tygacil are switched; to assess the duration of the intravenous therapy with Tygacil and to determine whether and which patients receive an oral antibiotic substance after the therapy with Tygacil; to collect information on profile, comorbidities and characteristics of patients treated with Tygacil.

Detailed description

Non-interventional study: subjects to be selected according to the usual clinical practice of their physician.

Interventions

DRUGtigecycline

The patients will be treated in accordance with the requirements of the labeling of tigecycline in Germany. The dosage and duration of therapy is to be determined by the physician to meet the patients' individual needs for treatment.
