Antibiotic Irrigations for Intra-Abdominal Drains

Total duration of systemic antibiotics will be recorded from the start of the treatment until discontinuation by primary care team. This will be measured as days from diagnosis to when the antibiotic treatment gets interrupted. Duration of systemic antibiotics will be our primary outcome measurement. Duration of systemic antibiotics will be monitored as an indication of the effectiveness of the proposed intervention.

White blood count level from the blood draw will be measured starting from the admission until discharge or discontinuation by primary care team. During follow up, if white blood count will be measured, will record up to 1 month follow up. The white blood count will be measured once daily and as needed depending on clinical changes. We will plan to trend WBC as another indication of decreasing systemic inflammation.

Temperature will be measured every 8 hours starting from admission and until patient discharge. And also temperature will be measured during each follow up clinic visit. Change in temperature is monitored as an indication of decrease systemic inflammation.

CT scan of would have been obtained prior to image guided drain placement. Any subsequent CT scans up to 1 month follow up upon discharge will be reviewed to assess changes in size of the abscess. This will be monitored for assessing the effectiveness of intervention.

Drain will have certain output that is recorded daily. Daily drain output will be in unit of ml and will be monitored as a measurement of abscess resolution.

The total duration of the drain placement will be recorded in days starting from the day of placement up to drain removal and monitored as a effectiveness of the intervention.
