5. Study Description
Brief Summary
Rationale: The Emergency Department (ED) typically serves as the front line for patients with acute fractures and tendon ruptures. Pain control for these patients is an essential task of the ED physician. With the advent of the opioid epidemic, ED physicians are becoming more inclined to prescribe non-narcotic pain medications such as non-steroidal anti-inflammatory drugs (NSAIDs). Yet, the effects of NSAIDs on musculoskeletal healing are controversial. The few human studies examining the effects of NSAID use on fracture healing have provided conflicting results. Even less is known about the effects of NSAIDs on tendon healing as this information has largely been gleaned from rodent studies with contradictory findings. There has never been a large, prospective, randomized, double-blinded study to determine the effects of NSAIDs on healing after fractures or tendon ruptures. Here, I propose to pilot the first prospective, randomized, double-blinded study examining the effects of NSAID use on healing after tibia fractures and Achilles tendon ruptures.
Aim 1 seeks to determine whether NSAID use is associated with an increased incidence of fracture nonunion and worse functional recovery six months following tibia fractures. I hypothesize that NSAID use after tibia fractures will be associated with an increased incidence of fracture nonunion and worse functional recovery. Aim 2 seeks to determine whether NSAID use is associated with worse functional recovery six months after Achilles tendon ruptures. I hypothesize that NSAID use after Achilles tendon ruptures will be associated with worse functional recovery.
Significance: Emergency Department providers commonly prescribe NSAIDs for pain control following fractures and tendon injuries. However, the implications of this practice on bone and tendon healing are unknown. This proposal will pilot the first prospective, randomized, double-blinded study to determine whether NSAID use affects healing after tibia fractures and Achilles tendon ruptures. Results from this study will impact NSAID prescribing patterns for tibia fractures and Achilles tendon ruptures in the ED, either by demonstrating that they impair recovery and should be avoided, or that they need not be withheld as an effective non-narcotic form of pain control.
Detailed Description
Specific Aims The Emergency Department (ED) typically serves as the front line for patients with fractures and tendon ruptures. Pain control for these patients is an essential task of the ED physician. With the advent of the opioid epidemic, ED physicians are becoming more inclined to prescribe non-narcotic pain medications such as non-steroidal anti-inflammatory drugs (NSAIDs). Yet, the effects of NSAIDs on musculoskeletal healing are highly controversial. There is some evidence that NSAIDs may prevent osteoblasts from rebuilding bone after fractures by inhibiting COX-2. Indeed, some retrospective studies have found NSAID use to be associated with an increased incidence of fracture nonunion after acetabular, tibial, and humeral shaft fractures, while other studies reported no difference. The only prospective randomized controlled trials evaluating the effects of NSAIDs on fracture healing reported no effect of NSAID use on healing after Colles fractures; however, these trials were likely underpowered to detect a difference in nonunion rates. Here, I propose to pilot the first large, prospective, randomized, double-blinded study examining the effects of NSAIDs on healing after tibia fractures, which are vulnerable to nonunion.
Similar to fractures, the effects of NSAIDs on tendon healing are unclear. Some studies suggest that NSAIDs may inhibit proliferation and migration of tendon cells after injury, while other studies indicate that NSAIDs enhance collagen synthesis. Rodent studies are equally conflicting, with some reports of worse outcomes associated with NSAID use and other studies showing no difference. Recently, I obtained preliminary data showing that NSAID use after Achilles tendon ruptures is associated with worse functional outcomes as measured by the Achilles Tendon Total Rupture Score (ATRS). While this was the first study examining the effects of NSAID use on recovery after Achilles tendon rupture in humans, the data were retrospective, observational, and not blinded. Here, I propose to pilot the first prospective, randomized, double-blinded study to determine the effects of NSAIDs on recovery after Achilles tendon ruptures.
Aim 1: Determine whether NSAID use is associated with an increased incidence of fracture nonunion and worse functional recovery six months after tibia fractures.
Hypothesis: I hypothesize that NSAID use after tibia fractures will be associated with an increased incidence of fracture nonunion and worse functional recovery.
Aim 2: Determine whether NSAID use is associated with worse functional recovery six months after Achilles tendon ruptures.
Hypothesis: I hypothesize that NSAID use after Achilles tendon ruptures will be associated with worse functional recovery.
Experimental Approach: Adult patients (18 years old and over) presenting to either the University of California Los Angeles (UCLA) Ronald Regan Emergency Department, the UCLA Santa Monica Emergency Department, or the UCLA Orthopedic after hours acute care clinic within 24 hours of sustaining a tibia fracture or Achilles tendon rupture will be screened for eligibility to participate. Patients will be excluded if they have a contraindication to Ibuprofen or Acetaminophen use, if they do not have access to e-mail, if they do not wish to participate, if they require emergent surgery (such as an open fracture), if they have a diagnosis of osteoporosis, or if they have already taken pain medication since their injury. Pregnant women will be excluded due to their inability to take NSAIDs. Children will be excluded due to differences in bone and tendon healing. The ED represents the optimal environment in which to conduct this study because most patients will initially present acutely to the ED with these injuries, often before taking any pain medication.
If patients elect to participate, they will be randomized to receive either Ibuprofen (600mg by mouth every 6 hours as needed for pain) or Acetaminophen (650 mg by mouth every 6 hours as needed for pain). I will use a permuted block design to develop the randomization schedule. Randomization will be stratified by sex. Sealed envelopes will be used to conceal the allocation. The treating physician will open the envelope and provide the assigned study medication and prescription bottle at discharge. Patients will be provided a one-month supply of their assigned pain medication. Patients and providers will be blinded to which medication the patient received. The individual medication capsules will be formulated to lack identifying information. Study coordinators will record the patients' randomly generated study identification number and prescription bottle number in Qualtrics, a HIPAA-compliant online resource that collects, stores, and analyzes data. Demographic information such as age and sex will also be stored in Qualtrics. Each week for one month, patients will be sent an email with a link asking them to complete a Qualtrics survey to report 1) the number of remaining pills, 2) their average pain scale ranging from 1-9, 3) what additional medications they took, if any, and 4) whether they have experienced any medication-related side effects or complications. In this way, we will determine the timing of medication administration for each patient and quantify each patient's level of pain, while assessing for patient safety.
Six months post-injury, patients who sustained tibia fractures will receive repeat X-rays. One final Qualtrics survey will be e-mailed to these patients at this time to determine their average degree of pain on a scale of 1-9, their functional recovery on a scale of 1 to 3 (mild, moderate, or severe impairment) and whether they underwent treatments such as physical therapy or surgery. The survey will also assess for lifestyle factors known to increase nonunion rates including body habitus, medical problems, and other medications taken.
Six months following enrollment, patients who ruptured their Achilles tendon will be sent a link to a Qualtrics survey via email. On this survey, they will be asked 10 questions with responses on a scale of 0 to 10 that comprise the ATRS (29). A higher score (out of 100) indicates better functional outcomes. Patients will also be asked if they underwent treatments such as physical therapy or surgery. Body habitus, medical problems, other medications taken, smoking status, pregnancy status, and fluoroquinolone use will also be assessed on this survey, as these factors may impact tendon recovery.
