Study of Respiratory Depression When Using a Hydromorphone Pain Protocol

Study Overview
=================
Brief Summary
-----------------
This is a study about the efficiency and safety of a 1mg+1mg hydromorphone pain management protocol for the treatment of moderate to sever pain in the Emergency Department. Appropriate patients 60 years and older who present with a condition that causes moderate to severe pain, according to the attending physician's judgment, in which the physician would order the use of parenteral analgesia will be enrolled in one of two study arms, 1+1 versus usual care group. 1+1 patients will receive 1mg hydromorphone followed by another 1mg after 15 minutes if pain persists. Usual care group patients will have pain treated per the discretion of the attending physician. Respiratory status, vital signs, and pain scores will be monitor to assess the efficiency of pain control as well as the safety of pain medicine administration in terms of respiratory depression.

Detailed Description
-----------------
This is a study about the efficiency and safety of a 1mg+1mg hydromorphone pain management protocol for the treatment of long bone fractures in the Emergency Department. Appropriate patients 60 years and older who present with a condition that causes moderate to severe pain, according to the attending physician's judgment, in which the physician would order the use of parenteral analgesia will be screened and randomized to one of two study arms, 1+1 versus usual care group. Neither the research associate, nurse, or attending physician will be blinded to the patients randomization. Patient pain score will be assessed at baseline using VAS score. 1+1 patients will receive 1mg hydromorphone at timepoint 0 (baseline) followed by another 1mg after 15 minutes (along with repeat VAS pain score) if the patient answers yes to Do you need more pain medicine? At 60 minutes, patient pain will be assessed a final time and if patient needs more pain medicine, additional treatment will be dictated by physician discretion. Usual care group patients will also have VAS pain scores assessed at timepoint 0, 15 and 60 minutes and will have pain treated per the discretion of the attending physician. Patients will be placed on capnometer for continuous monitoring of respiratory status to guard against any opioid induced respiratory depression. Respiratory status, vital signs, and pain scores will be monitor to assess the efficiency of pain control as well as the safety of pain medicine administration in terms of respiratory depression. We propose that the 1+1 hydromorphone protocol is easy to implement, as it includes a set timeline, a standard question, and a set dosage of a potent analgesic. We hypothesize that it will provide adequate analgesia in the majority of patients without causing the anticipated level of respiratory depression.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Active Comparator: 1mg + 1mg Hydromorphone<br>Patient will receive 1 mg of hydromorphone for pain at timepoint 0. After 15 minutes, patients will be asked if the still need pain medication. If yes, patients will immediately receive 1mg hydromorphone. Patients will be under continuous monitoring for respiratory depression via capnometer. At 60 minutes, pain will be re-assessed for a second time. If needed, physician will give additional pain meds per their discretion. | Drug: Hydromorphone<br>* 1mg of Hydromorphone at timepoint 0 and 1 mg of hydromorphone at 15 min timepoint.<br>* Other names: Dilaudid;|
| Active Comparator: Usual Care Group<br>Patient will receive pain medicine per doctor's discretion at timepoint 0. After 15 minutes, patients will be asked if they still need pain medication. If yes, physicians will not be notified and patient will continue to have pain managed as deemed necessary by physician per usual care. Patients will be under continuous monitoring for respiratory depression via capnometer. At 60 minutes, pain will be re-assessed for a second time. If needed, physician will give additional pain meds per their discretion. | Drug: Usual care group<br>* Patient will have pain treated at timepoint 0 as per usual care based on physician discretion. At 15 min timepoint, patients will be asked for pain level, and then subsequently treated as per physician discretion.<br>* Other names: Other IV opioid medications;|
