Brief summary

This trial is being completed to compare two commonly used options to treat pain after surgery. Participants that undergo gallbladder removal, hernia repair, and breast lump removal will be eligible to enroll. Eligible participants will be randomized to 1 of 2 groups of medications (Non-Steroidal Anti-Inflammatory Drugs (NSAIDS) plus acetaminophen or low dose opioids plus acetaminophen). It is anticipated that the NSAID group will have superior clinical outcomes and fewer side effects when compared to the opioid group.

Interventions

DRUGNSAID

Once randomized to this group the surgical team will elect for 1 of the following treatment options to be given: * Ibuprofen 600 milligram (mg) by mouth every six hours as needed for pain (10 doses) * Celecoxib 400 mg by mouth once then 200 mg every twelve hours as needed for pain (10 doses) * Naproxen 500 mg by mouth once then 250 mg by mouth every eight hours as needed for pain (10 doses)

DRUGOpioid

Once randomized to this group the surgical team will elect for 1 of the following treatment options to be given: * Oxycodone 5 mg by mouth every four to six hours as needed for pain, 10 doses * Morphine 7.5 mg by mouth every four to six hours as needed for pain, 10 doses * Hydromorphone 2 mg by mouth every four to six hours as needed for pain, 10 doses

DRUGAcetaminophen

Acetaminophen 1000 mg by mouth every 6 hours around the clock for the first three days after surgery then as needed thereafter (20 doses).

Masking description

Both study staff performing outcome assessment and data analysis will be masked to treatment assignment.

Intervention model description

Randomization of patients will be stratified by site, sex, age (greater or equal to 65 years old), and type of surgery, via permuted block randomization with a variable block size.

Inclusion criteria

* No significant analgesic medication use before surgery: For this study, significant analgesic medication use before surgery as use of prescriptions for opioid or NSAID medications in the past 30 days, or over-the-counter NSAID use on greater than 7 of 30 past days, as reported by the patient. * One of three common low-risk surgical procedures: For this study, the three-common low-risk surgical procedures will include laparoscopic gallbladder removal, inguinal hernia repair, and breast lumpectomy.

Exclusion criteria

* Anticipated other surgery within 6 months or anticipated life expectancy of less than 6 months * Patients with contraindications to NSAID drugs in the NSAID arm, opioid drugs in the OPIOID arm, or acetaminophen will be excluded. There are specific contraindications that will be reviewed per protocol.

Design outcomes

Primary

MeasureTime frameDescription
Pain intensity based on Brief Pain Inventory (BPI) pain intensity score at the surgical site over 7 days post surgery7 days post surgeryThis is a one question survey in which the worst pain intensity recorded (0-10 being the worst) will be used.
Safety outcome - number and severity of any adverse medication-related symptoms over 7 days post surgery7 days post surgerySymptom Checklist will proactively screen patients for reports of adverse events from analgesic medications over the first 7 days post surgery.

Secondary

MeasureTime frameDescription
Acute pain based on The Michigan Body Map7 days post surgeryParticipants will document/mark on this image map to identify areas in which persistent or recurrent pain was felt.
Healthcare Utilization related to pain at 1 monthwithin 1 months after surgeryParticipants will answer questions about their healthcare utilization related to pain for the time period from date of surgery to one month later for the following three events: (1) postoperative clinical interactions related to pain in the form of patient messages, phone calls, and non-routine clinic visits related to pain, (2) emergency room visits, and (3) hospitalizations. The study team will also review health record for the same events.
Patient Reported Outcomes Measurement Information System (PROMIS) Sleep Disturbance v1.0 4a questionnaire1 month post surgeryThis is a 4 question survey in which participants will rate statements pertaining to quality of sleep. Participants will also rate sleep quality as very poor (5), poor (4), fair (3), good (2), or very good (1).
Clinically important adverse events180 days post surgeryThe study team will review charts for unplanned postoperative clinical interactions related to pain (patient messages, phone calls, non-routine clinic visits related to pain) and emergency room visits, hospitalizations, and 30-day complications after discharge measured using the American College of Surgeons' (ACS) National Surgical Quality Improvement Program (NSQIP) definitions.
Patient Global Impression of Change (PGIC)up to 1 month after surgeryThe perception of improvement after treatment will be assessed by the patient global impression of change PGIC (range 0-7).
Quality of Recovery (QoR) 153 days post surgeryThere are 15 questions assessed on a scale of 1-10, with 0 being none of the time and 10 being all of the time, 10 being the better outcome.
PROMIS Pain Interference 4a3 monthsThis is a 4 question survey that assesses the degree to which pain interferes with various aspects of life. Items are scored on a 1 ("Not at all") to 5 ("Very much") scale with a range of 4 - 20. Higher scores indicate greater pain interference.
PROMIS Preference score 29+2 Profile v2.13 monthsThis is a 31 question survey that includes questions to evaluate each of 7 domains (physical function, anxiety, depression, fatigue, sleep disturbance, social functioning, and pain interference) using a 5- point Likert scale, as well as a single item to assess pain severity on a 0-10 scale as well as 2 questions for cognitive function. Higher scores are indicative of better health.
Substance use based on the Tobacco, Alcohol, Prescription medications, and other Substance (TAPS) tool180 days post surgeryThis National Institute on Drug Abuse (NIDA) TAPS tool has part 1 (5 questions) and part 2 (possible 9 questions).
National Survey on Drug Use and Health Questions (NSDUH) on Opioid Misuse opioid misuse question3 months
New prolonged opioid usedays 4-180 post surgeryThis will include greater or equal to 1 opioid prescription post-discharge between 4-180 days post discharge.
Chronic pain based on Brief Pain Inventory (BPI) pain intensity score at 180 days post surgery180 days post surgeryOne question survey in which the participants rate pain intensity recorded (0-10), ten being the worst.
Healthcare Utilization related to pain at 6 monthswithin 6 months after surgeryParticipants will answer questions about their healthcare utilization related to pain for the time period from date of surgery to six months later related to pain for the following three events: (1) postoperative clinical interactions in the form of patient messages, phone calls, and non-routine clinic visits related to pain, (2) emergency room visits, and (3) hospitalizations. The study team will also review health record for the same events.
Chronic pain based on Body Map180 days post surgeryParticipants will document/mark on this image map to identify areas in which persistent or recurrent pain was felt.
