详细说明
We hypothesize that a clinical decision support system (CDSS) designed with "Patient-specific" reminders yields superior performance than that with "Non-patient-specific" reminders in preventing contrast-induced nephropathy.
A 3-arm randomized controlled trial (RCT) will be performed by cluster randomization using physicians as the unit of allocation. Physicians in 3 university medical centers will be randomly assigned into 1) patient-specific arm with Anti Contrast-Induced-Nephropathy(Anti-CIN) reminder, 2) non-patient-specific reminder arm, and 3) the control arm without any reminders, respectively.
The patient-specific alert, Anti-CIN system, is designed as a real-time CDSS implementation on CPOE for monitoring physician's contrast-enhanced CT and IVP orders. Computerized pop-up reminders provide the patient-specific encounters with optimal decision options when patients are at a high CIN risk or patients with unknown risk factors are encountered. Non-patient-specific reminders always pop up no matter whether the patient is at a high risk or not.

描述
Inclusion Criteria:
- Our intervention targets are physicians but not patients. All physicians working in the hospital may join this trial.
Exclusion Criteria:
- The physician who never orders a CT scan or IVU study will be excluded
- The physician who never operates the CPOE by himself or herself will be excluded

实验性的:Patient-specific reminder
Intervention: Patient-specific computerized reminder.
The physicians assigned to this arm will use the patient-specific CDSS on CPOE.
The patient-specific reminder is designed as a real-time CDSS implemented on CPOE to monitor physician's contrast-enhanced image study orders.
Computerized pop-up reminders provide the patient-specific CIN risk profile and optimal decision options which are generated when patients with high risk or with unknown risk of CIN are encountered.
|
The intervention targets are physicians,not patients.
This CDSS alerts physicians only when the patient with high risk of contrast-induced-nephropathy(CIN) is encountered.
On the contrast, the CDSS will not alert when the patient without CIN risk is encountered.

有源比较器:Non-patient-specific reminder
Intervention: Non-patient-specific Computerized reminder.
The physicians assigned to this arm will use the Non-patient-specific reminders through CPOE.
Non-patient-specific reminders always pops up to remind physicians to check their patient's CIN risk no matter what CIN risk is.
