Opiate Prescribing Guidelines Following Hip Arthroscopy

Study Overview
=================
Brief Summary
-----------------
The purpose of the study is to determine if opiates are required to achieve appropriate analgesia after hip arthroscopy in outpatient surgery. The investigators hypothesize that patients are frequently prescribed more opiates than are needed after surgery, resulting in excess medications that are at risk for misuse, diversion and contribution to the opioid epidemic

Detailed Description
-----------------
Perioperative pain management is an important aspect of quality patient care. Opioid pain medications are increasingly being used for pain control, with the United States writing over 250 million prescriptions for painkillers per year. Increased usage has led to unintended negative consequences for individuals and society. It is estimated that 46 people die each day from an overdose of prescription painkillers, and individual use can lead to the development of tolerance and worse treatment outcomes. Further issues arise when opioids are misused, it is estimated that nontherapeutic use has increased three fold in recent years. In the United States alone in 2006 the estimated total cost of opioid prescription misuse was $53.4 billion, of which $42 billion was attributed to lost productivity, $8.2 billion to criminal justice cost and the remainder drug abuse treatment and medical complications. The federal government has recognized this epidemic and raised a call for clinicians to more responsibly prescribe opiate pain medications Opiate use has increased in recent years, from 2000-2010 the use of opiates in office based visits nearly doubled from 11.3% to 19.6% whereas there was no change in the prescribing of non-opioid pharmacotherapies. Further, when specifically looking at new musculoskeletal pain visits, one half resulted in pharmacologic treatment, with the prescribing of non-opioid pharmacotherapies decreasing from 38% to 29% from 2000 to 2010, respectively. The clinical use of opioids for post-operative pain control has also been linked to the opioid epidemic and risk of future abuse. Legitimate opioid use before high school graduation is independently associated with a 33% increased risk of future misuse after high school. It has been estimated that orthopedic surgeons prescribe 7.7% of all opioids in the United States.Special attention needs to be paid to the amount of opioid pain medications orthopedic surgeons prescribe to patients after ambulatory surgery, there is considerable variability among surgeon and procedure in regards to the amount of opioids to prescribe with many patients left with excess unused medication .An analysis of 250 patients undergoing outpatient upper extremity surgery found that on average patients consumed 10 opioid pills, with 19 pills left over and a total of 4,639 pills going unused in the cohort. Leftover prescription opioids are at risk for diversion to family and friends for nonmedical use. Further studies are needed to quantify the amount of opioids to prescribe for specific orthopedic procedures to limit excess narcotic use, misuse, diversion and contribution to the opioid epidemic.
