Introduction. Despite evidence-based recommendations opioids and benzodiazepines are commonly prescribed to treat osteoarthritis. This study aims to quantify the prevalence of opioid and benzodiazepine prescriptions given for the primary diagnosis of osteoarthritis across a large healthcare system. Additionally, we aim to characterize risk factors for drug misuse, abuse, and diversion. Methods. We conducted a descriptive analysis of adult patient encounters with a primary diagnosis of osteoarthritis during a one-year time period from Jan –Dec 2016 at a large, healthcare system. Demographic data, prescription data, patient-specific prescription drug use risk criteria were collected. Descriptive analysis was conducted to characterize the population of arthritis patients who received prescription opioids. The rate of controlled substance prescribing was calculated for the population as a whole and among subgroups (age, facility type, and patient risk profile). Results. During the one-year time frame, our system had 45,341 outpatient encounters with a primary diagnosis of osteoarthritis. Almost a third of these encounters resulted in a prescription for an opioid or benzodiazepine (n = 7,375; 31.9%). The majority of patients were between ages 18 and 64 (57.1%), with 42.9% patients >65. While 38.8% were prescribed in an acute care setting (ED or Urgent Care), the majority were in outpatient clinics (58.8%) with 36.2 % of outpatient encounters originating from orthopaedic clinics. 14.3% of those who received a prescription had a risk factor for prescription misuse, the most prevalent being “early refill” (7.0%). Conclusion. Opioids remain a prevalent treatment for osteoarthritis, given in over a third of encounters. These prescriptions pose a risk for adverse outcomes, since over a third of patients had a risk factor for misuse. Continued efforts to improve compliance with evidence-based guidelines as well as alternative pain management pathways are critical to help curb the use of opioids for management of osteoarthritis

Introduction. Opioids are an important component of multimodal analgesia, but improper utilization places patients at risk for overdose and addiction. The purpose of this randomized controlled trial is to determine whether the quantity of opioid pills prescribed at discharge is associated with the total amount of opioids consumed or unused by patients after total hip (THA) and knee (TKA) arthroplasty. Methods. 304 Opioid naïve patients undergoing THA or TKA were randomized to receive a prescription for either 30 or 90 5mg oxycodone immediate release (OxyIR) tablets at discharge. All patients received acetaminophen, meloxicam, tramadol and gabapentin perioperatively. Daily opioid consumption, reported in morphine equivalent dose (MED), number of unused OxyIR, and pain scores were calculated for 30 days postoperatively with a patient-completed medication diary. The number of OxyIR refills and total MED received were recorded for 90 days postoperatively. Power analysis determined that 141 patients per group were necessary to detect a 25% reduction in means in opiate consumption between groups. Statistical analysis involved t-test, rank sum, and chi-squared tests with alpha=0.05. Results. 161 Patients were randomized to receive 30 tablets and 143 to receive 90. In the first 30 days, the median number of unused OxyIR tablets was 15 in the 30 group versus 73 in the 90 group (p<0.0001). Within 90 days of discharge, 26.7% of the 30 group and 10.5% of the 90 group requested a refill (p<0.001), leading to a mean of 777.1 MED versus 1089.7 prescribed (p<0.0001). There was no difference between groups in mean MED consumed and pain scores within the first 30 days. Baseline demographics and outcome scores were similar between groups suggesting appropriate randomization. Conclusion. Prescribing a smaller number of opioids at the time of surgery is associated with equivalent pain scores and opioid consumption yet a significant reduction in unused narcotics

Aims

The aim of this study was to determine whether total hip arthroplasty (THA) for chronic hip pain due to unilateral primary osteoarthritis (OA) has a beneficial effect on cognitive performance.

Aims

It has been suggested that the direct anterior approach (DAA) should be used for total hip arthroplasty (THA) instead of the posterior approach (PA) for better early functional outcomes. We conducted a value-based analysis of the functional outcome and associated perioperative costs, to determine which surgical approach gives the better short-term outcomes and lower costs.

Aims

Natural Language Processing (NLP) offers an automated method to extract data from unstructured free text fields for arthroplasty registry participation. Our objective was to investigate how accurately NLP can be used to extract structured clinical data from unstructured clinical notes when compared with manual data extraction.

Aims

To examine incidence of complications associated with outpatient total hip arthroplasty (THA), and to see if medical comorbidities are associated with complications or extended length of stay.
