The purpose of this study is to evaluate the impact of a structured package (bundle) in reducing the use of antimicrobials and hospital stay of patients with community-acquired pneumonia (CAP), and no increase in mortality of these patients in different hospitals.

Inclusion Criteria:

• Diagnosis of CAP at hospital admission .
• Age: 18 years or more.

• Patient treated with immunosuppressive drugs.

Pre-intervention period

All patients admitted with a diagnosis of CAP will be included in the participating centers during the 12 months prior to the intervention. Case detection is done through the electronic record of the basic minimum data set (MDS) (2, 36). Diagnosed patients will be selected at discharge: "simple acute bronchitis and pneumonia excluding asthma major criteria" (by diagnosis related group, DRG 541) and "simple and pleuritis in over 17 Pneumonia" (DRG 089).

Post-intervention period

All patients admitted with a diagnosis of CAP in the participating centers, which measures the bundle will apply prospectively included. Case detection was performed by daily review of patients admitted to target units and will be coordinated by the IP address of each center.
