What researchers measure

Primary outcomes

  1. Patient Demographics

    Medical history is information which was collected at the CDI diagnosis in this study. The items of the Medical history are indicated below. Concomitant diseases at the CDI diagnosis were included in the Medical history.

    Time frame: At the study at the time of CDI diagnosis enrollment

  2. Status at the End of CDI Episode

    The patients were observed from the diagnosis to the end of the treatment and got a telephone follow up call after two month from the end of treatment. The categories of the status indicating below are at the end of the treatment, not at the follow up call. Lost to follow-up means the patient number who were lost during the treatment course.

    Time frame: From the time of CDI diagnosis to the end of the treatment

Secondary outcomes

  1. Clinical Complication

    This study was non-interventional observational study. There were no restriction on the CDI treatment and we did not define to collect AE data. We just defined to collect the data for complications with CDI treatments indicating below. The complications to be checked were defined in the protocol. The information of other complications and AEs were not collected.

    Time frame: From the time of CDI diagnosis to recovery or recurrence

  2. Recurrence or Not After 2 Months Follow-up

    The patients were observed from the diagnosis to the end of the treatment and got a telephone follow up call after two month from the end of treatment. Unknown includes patient lost, data missing

    Time frame: From the time of CDI diagnosis to 2 months follow-up

Timeline

Tracking since Sep 25, 2026
Not marked actual or estimatedDates not marked actual or estimated

The record gives a start of Mar 2014, a primary completion of Jan 2015 and a completion of Jan 2015. It does not say whether these dates are actual or estimated.

Results were first posted in Oct 2016, 1 year 9 months after primary completion.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Oct 17, 2016, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
