Abstract
Background
Narcotics are commonly prescribed for pain control of orthopedic trauma but injury pattern and severity, in addition to patient factors, result in varying dosing requirements. These factors, coupled with increasing pressure to reduce narcotic consumption, highlight the importance of narcotic stewardship and comprehension of patient factors leading to higher pain control demands. The purpose of this study is to understand whether or not narcotic consumption is greater in patients who present to the emergency department with positive drug screen (utox) for illicit substances.
Methods
We performed a retrospective chart review of 300 consecutive trauma activations during the 2015 calendar year. Of the patient cohort, 226 patients received a utox screen which represents the cohort for this study. Utox screen included amphetamines, barbiturates, benzodiazepines, cocaine, ethanol, methadone, phencyclidine, and tetrahydrocannabinol. Opioids given hospital stay were converted to oral morphine equivalents using ratios available in the current literature. The average daily equivalent was calculated for their total hospital stay and recorded. Patient injury severity score (ISS), age, gender, length of stay, readmission rates were also recorded. Statistical comparisons were made using SPSS version 23 (IBM, Aramonk, NY). Data distributions were examined with the Shapiro-Wilk test of normality between group comparisons were made with Mann Whitney U tests. Chi squared test was used to evaluate categorical data. Significance was set at p=0.05.
Results
There were 108 (48%) positive utox tests of the 226 that received a utox test. There was no difference in gender distribution or age between the 2 groups. The calculated morphine equivalent consumption of the positive utox patient cohort was compared against the negative utox group. The median daily oral morphine equivalents in the positive utox group was 23.85 versus 12.05 for those with a negative utox screen. This was found to be statistically significant with a p value of 0.014. The average length of stay for the positive utox group was 3 days versus 2 days for the negative utox group. This also was statistically significant with a p value of 0.009. There was no statistical significance for ISS (5 in utox positive versus 5 in utox negative patients) nor was there any significance found in the rate of readmissions.
Discussion
Our study shows that infividuals found to have positive utox screening for illicit drug use require more opioids for pain control and have longer hospital stays. These increased resource requirements exist despite no statistically significant difference in ISS. The high rate of positive findings and differences in patient clinical course support continued utox screening in trauma activation patients. When treating these patients, physicians should be aware of potential differences in pain management strategies and would likely benefit from multimodal pain control progam.
