Title: Operational Assessment of Laboratory Information System for MDR-TB in Lima, Peru
Brief Summary: The objective of this study is to compare the effects of a web-based laboratory information system (e-Chasqui) between a network of health establishments with access to e-Chasqui (intervention group) and a network of health establishments without access to e-Chasqui (control group).

The specific aims are:

1. To compare the "laboratory turn-around-time" (from the date a culture or drug susceptibility test (DST) result is obtained to the date the result is obtained at the health center) of samples pertaining to health establishments in the intervention versus the control group.
2. To compare the "clinical turn-around-time" (from the date the DST result is obtained to the date the patient is evaluated by a physician in possession of that result) among multi-drug-resistant tuberculosis (MDR-TB) patients pertaining to health establishments in the intervention versus control group.
3. To compare the laboratory reporting errors (defined as incorrect smear, culture, or DST results) between health establishments in the intervention versus control group.
4. To qualitatively assess the acceptability and usability of e-Chasqui among users in health establishments with access to the system.

The investigators aim to test the following hypotheses:

1. The laboratory turn-around-time for health establishments with e-Chasqui access will be smaller than that for establishments without e-Chasqui access.
2. The clinical turn-around-time for patients pertaining to health establishments with e-Chasqui access will be smaller than that for patients in establishments without e-Chasqui access.
3. Health establishments with e-Chasqui access will have fewer errors compared to those without e-Chasqui access.
4. Factors associated with acceptability and usability of e-Chasqui by systems users can be identified.
