Orthopedic resident education on postoperative pain control: bridging knowledge gaps to enhance patient safety.

As the United States population continues to age, the number of orthopedic procedures continues to grow.1 Not infrequently, many of these patients who are admitted for orthopedic surgical procedures are already on complex pain regimens preoperatively. This is due not only to the increasing comorbid state of our aging population but also the wide variety of analgesic management strategies employed throughout the nation amid chronic opioid use.2 Expanding surgical volumes, particularly when involving increasingly complex and opioid-tolerant chronic pain patients, pose significant challenges for perioperative management. Inpatient hospital pain services3,4 can be of tangible benefit for these complex pain patients.5 Miaskowski and colleagues found that patients cared for by an acute pain service were discharged sooner, had lower pain intensity scores, lower incidences of pruritis, sedation and nausea compared to those without the anesthesia service involvement.5 With a growing number of surgical cases, pain management consultations have increased to a number that is not always sustainable, leading some hospitals to adopt a nurse care model.6 There is minimal medical literature assessing the types of pain management consultations.4 A local and unpublished study on resource utilization at Mayo Clinic Rochester demonstrated that orthopedic surgeons place roughly 40% of all surgical specialty consultation requests for acute postoperative pain management. The majority of these consultations are requests for pharmacologic analgesia management, such as titrating oral narcotic medications. A smaller number of these requests are focused on interventional pain procedures, such as joint injections. Since not all hospitals have dedicated inpatient pain services, this places additional pressure on surgeons in the perioperative period, making pain education for these specialties even more important. To improve postoperative pain management, the inpatient pain medicine service at Mayo Clinic, a subspecialized physician practice with credentials specifically in Pain Medicine, founded an educational seminar for the incoming orthopedic surgery residents. The purpose of this program was to optimize their understanding of the role that the inpatient pain service plays in managing postoperative pain, as well as to educate them in the founding principles of pharmacologically-directed pain management. Educational Seminar In 2011, the Orthopedic Staff Leadership Committee (OSLC) at the Mayo Clinic, which consists of a core group of staff nurses and nursing leadership, participated in an educational seminar with new orthopedic residents to help guide them through the dynamic perioperative hospital course to ensure safe, satisfactory patient care. These residents received clinical education from various hospital groups, including physical and occupational therapy, social services and pharmacy. The seminars guided them through clinical techniques, such as surgical wound management, pressure ulcer prevention, and proper application of splints and casts. As an extension of this training, the OSLC, in conjunction with the Anesthesiology Division of Pain Medicine, developed a seminar to orient the resident trainees to common strategies of postoperative pain management. The training seminar consists primarily of a one-day, three-hour discussion and didactic lecture. This lecture is presented by a core faculty member of the division of Pain Medicine. The core principles it addresses are the nuances of the functions of the Anesthesia Acute Pain Management Hospital Service, as well as the pharmacodynamic and pharmacokinetic principles of a number of common medications used in the postoperative setting. These include medications such as oral and IV narcotics, NSAIDs, Tylenol, topical local anesthetics, and Tramadol. Specific information on opioid titration, parenteral to oral opioid conversion, and postoperative opioid weaning strategies (once healed from surgery) was also provided. The content consisted of defining the concept of multimodal analgesia, reviewing opioid pharmacokinetics and pharmacodynamics, demonstrating how to calculate oral morphine equivalents, understanding the utility of regional anesthesia, and reviewing methadone and pharmacokinetics and pharmacodynamics. A pre and post-assessment, audience response system test was given to improve attention and retention.
