Brief Summary

The investigators 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.

Conditions

Radiographic Contrast Agent Nephropathy

Keywords

Clinical Decision Support Systems; Contrast-induced nephropathy

Outcome Measures

Primary Outcomes (1)

• The percentage of contrast-enhanced imaging(CEI) orders with high CIN risk

  The number of CEI ordered for patients at high CIN risk, divided by the total number of CEI orders. \[CEI\]: contrast-enhanced image studies,such as CT or IVU. \[CIN\]: contrast-induced nephropathy

  Physicains who participated in this trial will be followed for an expected average of 12 months

Secondary Outcomes (1)

• The order elimination rate of high CIN risk orders attributed to the computerized reminder

  Physicains who participated in this trial will be followed for an expected average of 12 months

Study Arms (3)

Patient-specific reminder

EXPERIMENTAL

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.

Other: Patient-specific computerized reminder

Non-patient-specific reminder

ACTIVE COMPARATOR

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.

Other: Non-patient-specific computerized reminder

Control Arm

NO INTERVENTION

The physicians assigned to this arm will not use and any computerized reminder.

Interventions

Patient-specific computerized reminder OTHER

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.

Also known as: Patient-specific CDSS

Patient-specific reminder

Non-patient-specific computerized reminder OTHER

The non-patient-specific computerized reminder always pops up to remind physicians to check their patient's CIN risk no matter what CIN risk is.

Also known as: Non-patient-specific CDSS

Non-patient-specific reminder

Eligibility Criteria

• Age: 25 Years - 70 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Our intervention targets are physicians but not patients. All physicians working in the hospital may join this trial.

You may not qualify if:

• 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
