Impact of Different Educational Approaches on Post-operative Opiate Utilization After Elective Lower Extremity Surgery

Hypothesis: The primary hypothesis is that the educational intervention provided prior to the
surgery and prior to the prescription, will result in a greater understanding and awareness
of the deleterious effects of long-term use of opioid based medications, and in turn reduce
utilization post-operatively in the long-term (6 months).

Specific Aim 1: Evaluate prescription opioid medication use for the 6-month period after
surgery in subjects that received the education compared to those that received usual care
education.

Specific Aim 2: Compare the changes in self-reported outcome measures (pain, disability, and
sleep) between groups over the 6-month period after surgery.

Specific Aim 3: Describe the sociodemographic factors and healthcare utilization in enrolled
subjects for the 12 months leading up to a surgical procedure. Identify factors that could
account for differences in opioid medication utilization, and any potential interaction
effect between intervention, opioid use, and clinical outcomes following surgery.

Study Procedures/Research Interventions:

Subjects will be randomized to either receive usual care only or usual care plus the
education video. Usual care is defined as typical information the surgeon would otherwise
provide the patient before surgery. All patients will receive the usual care education from
their surgeon.

Randomization:

Subjects will then be randomized into one of two arms (Group I = Educational Video, Group II=
Usual Care Only). The method of group assignment will be sequentially numbered opaque sealed
envelopes (SNOSE). To minimize the risk of predicting the treatment assignment of the next
eligible patient, randomization will be performed in permuted blocks of two or four with
random variation of the blocking number.

All Subjects:

All subjects will receive the usual care education that is typically given by their surgeon.
That will be left up to the discretion of each surgeon. The screening and enrollment should
take no more than 5-10 minutes, and then the filling out of self-report questionnaires should
take approximately 5-7 minutes. Subjects in the group that is randomized to the education
will take an additional 11 minutes to view the educational content.

All patients will proceed with the surgical procedure as planned. Each week during the
1-month period after the surgery, patients will be contacted (phone call, email, and text
message - depending on what they consented to).

At the 1-month and 6-month time points they will be asked to fill out the additional clinical
outcomes measures detailed below. These can be done in person with a visit to the clinic or
over the telephone.

Sample Size Estimation. Collection of healthcare utilization will occur in 100% of the
subjects as no follow-up is required, and therefore no opportunities to collect data from a
follow-up visit will be lost. A sample of 120 subjects should allow us to determine
significant differences between groups, based on a moderate effect size of 0.6.

Inclusion Criteria:

1. Any Tricare-eligible patient scheduled for a pre-operative surgery appointment for an
elective orthopaedic surgery of the hip, knee, or foot/ankle at SAMMC.

2. The surgery is taking place for a condition that has been ongoing for 6 months or
longer (chronic)

3. Between the age of 18 - 65 years

4. Read and speak English well enough to understand the education, provide informed
consent and follow study instructions (the surgeon, investigators, or research
assistants will make this determination. Any patient that needs an interpreter will
not be allowed to enroll).

Exclusion Criteria:

1. Known aversion or allergy that would prevent the patient from taking any opioid-based
pain medication (any contraindications to using opioids)

2. History of prior surgery to the same location.
