Comparing Individualized vs. Weight Based Protocols to Treat Vaso-Occlusive Episodes in Sickle Cell Disease (COMPARE-VOE)

June 13, 2023 updated by: Duke University

A Comparison of Individualized vs. Weight Based Protocols to Treat Vaso-Occlusive Episodes in Sickle Cell Disease

The purpose of this research study is to compare two different ways to give opioid pain medicine to treat sickle cell disease pain that is bad enough to go to the emergency department for treatment. One way uses your weight to decide how much pain medicine to give you while in the emergency department. This is called weight based treatment. The other way uses how much pain medicine you take at home and how much medicine you needed during past emergency department visits to decide how much medicine to give you. This is called patient specific treatment.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

No

Description

Inclusion Criteria:

  • All adult (18 years or older);
  • Sickle Cell Disease patients with the following genotypes: Hgb SS (sickle cell anemia), SC(Sickle hemoglobin-c) , and SB+(sickle Beta-Plus thalassemia) and SB-(sickle Beta zero thalassemia)

Experimental: Patient-Specific Protocol
Patients assigned to this treatment protocol will be given pain medicine(s) based on the pain medicine(s) they take at home, what was needed during their past hospital and emergency department visits to treat pain and doses that have been effective and safe in the past.
Other: Patient-Specific Protocol
Patients assigned to this treatment protocol will be given pain medicine(s) based on the pain medicine(s) they take at home for pain and what was needed during their past hospital and emergency department visits to treat pain. Medicines will include opioids, either morphine or hydromorphone. A member of the outpatient SCD provider team will review the patient's medical record to determine: 1) the patient's maximum home opioid dose, and 2) previous ED analgesic medication(s) and doses that have been effective and safe in the past. The patient's regular hematologist/sickle cell team will write the treatment plans. Medications will be given every 20-30 minutes for up to 6 hours.
Drug: Morphine
4 mg for participants weighing <50 kgs, 6mg for participants weighing 50-69.9 kgs, 8mg for participants weighing 70 - 89.9 kgs and 10mg for participants weighing greater than or equal to 90 kgs. dose is given. Re-dosing is every 20-30 minutes up to 6 hours with one possible dose escalation of 25%.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
The Change in Pain Score
Time Frame: baseline (bed placement), to disposition decision or a maximum treatment duration of 6 hours, whichever came first
Pain is measured by having the patient mark pain on a scale of 0 to 100, with 0 being no pain and 100 being the worst pain ever. Pain scores were initially measured using a 0-100 millimeter visual analog scale with higher (closer to 100 being worse); however during the COVID-19 pandemic, one site removed paper forms from the emergency department as an infection control measure. The protocol was amended to add collection of a 0-100 verbal numerical rating scale and sites were ask to obtain both a vision and verbal score if possible collecting the visual score first. For the analysis, the visual score was used if available for the primary outcome. if not available, the verbal score was used.
baseline (bed placement), to disposition decision or a maximum treatment duration of 6 hours, whichever came first

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.

Length of Index ED (Emergency Department) Stay
