Arm | Intervention/treatment |
---|---|
Experimental: Null setting, forced entry
Each arm sets the default quantity (preset quantity) embedded in the electronic medical record for study opioids. This arm has a default setting for opioid quantity set at -blank-. This setting required the prescriber to enter a quantity in order to write a prescription. |
Other: Default settings for opioid prescriptions (acetaminophen/hydrocodone, oxycodone, acetaminophen/oxycodone)
For each of the arms, the investigators modified the default setting for the dispense quantity of study opioids on the electronic medical record settings for discharge prescriptions. Study drugs include acetaminophen 325mg + hydrocodone 5mg, acetaminophen 325mg + hydrocodone 7.5mg, acetaminophen 325mg + hydrocodone 10mg, oxycodone 5mg, acetaminophen 325mg + oxycodone 5mg, acetaminophen 325mg + oxycodone 10mg. |
Experimental: 5 tablet default
Each arm sets the default quantity (preset quantity) embedded in the electronic medical record for study opioids. This arm has a default setting for opioid quantity set at 5. |
Other: Default settings for opioid prescriptions (acetaminophen/hydrocodone, oxycodone, acetaminophen/oxycodone)
For each of the arms, the investigators modified the default setting for the dispense quantity of study opioids on the electronic medical record settings for discharge prescriptions. Study drugs include acetaminophen 325mg + hydrocodone 5mg, acetaminophen 325mg + hydrocodone 7.5mg, acetaminophen 325mg + hydrocodone 10mg, oxycodone 5mg, acetaminophen 325mg + oxycodone 5mg, acetaminophen 325mg + oxycodone 10mg. |
Experimental: 10 tablet default
Each arm sets the default quantity (preset quantity) embedded in the electronic medical record for study opioids. This arm has a default setting for opioid quantity set at 10. |
Other: Default settings for opioid prescriptions (acetaminophen/hydrocodone, oxycodone, acetaminophen/oxycodone)
For each of the arms, the investigators modified the default setting for the dispense quantity of study opioids on the electronic medical record settings for discharge prescriptions. Study drugs include acetaminophen 325mg + hydrocodone 5mg, acetaminophen 325mg + hydrocodone 7.5mg, acetaminophen 325mg + hydrocodone 10mg, oxycodone 5mg, acetaminophen 325mg + oxycodone 5mg, acetaminophen 325mg + oxycodone 10mg. |
Experimental: 15 tablet default
Each arm sets the default quantity (preset quantity) embedded in the electronic medical record for study opioids. This arm has a default setting for opioid quantity set at 15. |
Other: Default settings for opioid prescriptions (acetaminophen/hydrocodone, oxycodone, acetaminophen/oxycodone)
For each of the arms, the investigators modified the default setting for the dispense quantity of study opioids on the electronic medical record settings for discharge prescriptions. Study drugs include acetaminophen 325mg + hydrocodone 5mg, acetaminophen 325mg + hydrocodone 7.5mg, acetaminophen 325mg + hydrocodone 10mg, oxycodone 5mg, acetaminophen 325mg + oxycodone 5mg, acetaminophen 325mg + oxycodone 10mg. |
Active Comparator: Status quo default setting
Each arm sets the default quantity (preset quantity) embedded in the electronic medical record for study opioids. This arm has a default setting for opioid quantity set at the status quo value for each site (20 for site 1, 12 for site 2). |
Other: Default settings for opioid prescriptions (acetaminophen/hydrocodone, oxycodone, acetaminophen/oxycodone)
For each of the arms, the investigators modified the default setting for the dispense quantity of study opioids on the electronic medical record settings for discharge prescriptions. Study drugs include acetaminophen 325mg + hydrocodone 5mg, acetaminophen 325mg + hydrocodone 7.5mg, acetaminophen 325mg + hydrocodone 10mg, oxycodone 5mg, acetaminophen 325mg + oxycodone 5mg, acetaminophen 325mg + oxycodone 10mg. |
- Dispense quantity of prescribed opioids [ Time Frame: Through study completion, approximately 340 days ]The dispense quantity of prescribed study drugs was collected from the electronic medical record at each site. The mean and median quantities per prescription according to each study arm were compared.
- Proportion ≤12 [ Time Frame: Through study completion, approximately 340 days ]The dispense quantity of study drugs was collected from the electronic medical record at each site. The proportion of prescriptions at 12 or fewer tablets was compared across study arms.
- Proportion at default setting [ Time Frame: Through study completion, approximately 340 days ]The dispense quantity of study drugs was collected from the electronic medical record at each site. The proportion of prescriptions written for the given default setting was compared across treatment arms.
