BACKGROUND:: The value of order sets for clinical decision support has not been established. OBJECTIVE:: To determine whether introduction of admission order sets increases the proportion of inpatients receiving deep venous thrombosis (DVT) prophylaxis. DESIGN:: Before-after study. SETTING:: Community hospital. PATIENTS:: General medical patients admitted to hospital. INTERVENTION:: Paper-based admission order sets (instead of free-text orders) for voluntary use by internists, without any education or behavior change interventions. MEASUREMENTS:: Primary outcome was proportion of medical admissions ordered DVT prophylaxis. Secondary outcomes included overall utilization of DVT prophylaxis in medical inpatients and other admission order care quality measures. RESULTS:: Prior to introduction of order sets, DVT prophylaxis was ordered in 10.9% of patients. Patients admitted with order sets were more likely to be ordered DVT prophylaxis than patients admitted with free-text orders (44.0% versus 20.6%, by months 14 and 15, P < 0.0001). Hospital-wide DVT prophylaxis in medical inpatients increased from 12.8% to 25.8% of patient-days (P < 0.0001). Order set use improved many other secondary outcomes (P < 0.05 for all), including allied health consultations (62.8% versus 12.7%), use of standardized diabetic diet (17.0% versus 5.1%), insulin sliding scale (19.1% versus 7.6%), potassium replacement protocol (63.8% versus 0.51%), documentation of allergies (54.3% versus 9.6%) and resuscitation status (57.4% versus 10.2%), and reduced orders for inappropriate laboratory tests such as blood urea nitrogen (39.4% versus 59.0%). CONCLUSIONS:: The broad impact of order sets and minimal organizational resources required for their implementation suggests that order sets may have wide applicability as a clinical decision support tool.
