a novel usage of transdermal scopolamine in reducing narcotic usage in outpatient hand surgery

Conditions: Post Operative Pain Management

Summary: the investigators will examine and analyze opioid narcotic usage patterns by requesting patients keep a two week log of their opioid usage following outpatient hand surgery with a standard analgesic regimen consisting of an opioid, nsaid, and acetaminophen. following a pre-intervention period, the investigators will add scopolamine to the regimen and have patients monitor their opioid consumption. the investigators will then compare opioid consumption patterns following completion of the study.

aim 1: determine whether the addition of transdermal scopolamine to a standard analgesic regimen reduces opioid utilization following outpatient hand surgery as reported by patients objectives: the investigators will compare opioid usage between patients who complete logs during the pre-intervention stage of the study and the intervention stage of the study to determine the effect of including scopolamine as a medication in standard post-operative analgesic regimens following outpatient hand surgery. as this is the primary objective of our study, an a priori power analysis was conducted. based on a two-sided two-sample independent t-test with a specified significant level of 0.05, a power of 0.8, and a moderate effect size of 0.5; 64 patients will need to complete each portion of the study to provide an overall sample size of 128 patients. outcome variables and analysis: the absolute number of logged opioid use during the two-week study period will be compared between the pre-intervention and intervention groups using a two-sided independent samples t-test. aim 2: determine patient compliance with usage of multi-modal analgesic medications and the feasibility of supplementing with an additional agent objectives: during the pre-intervention stage of the trial, the investigators will encourage patients to utilize non-opioid analgesics over opioids and have patients keep a log of their nsaid and acetaminophen usage. this aim will partially establish whether patients are being adequately counseled regarding multi-modal pain control as patients with high opioid consumption should also have high rates of use of their non-opioid analgesics. it will also establish whether it is feasible to expect patients to comply with the introduction of novel medications into analgesic regimens. it will establish baseline rates of non-narcotic pain medication use overall and stratified by procedure. it may also further support the existing evidence that non-opioid pain medications reduce opioid requirements while providing more significant pain relief than opioids alone. outcome variables and analysis: data analyzed will include percentage of individual non-opioid pain medications used (prescriptions will be provided so patient could take medication around the clock), patient pain scores, and percentage of opioids used. percentages of non-opioid pain medications and opioid pain medications will be compared on a patient-by-patient basis by utilizing a paired t-test. the association between patient perceived pain levels and percentage of each medication used will be determined with multiple linear regression. aim 3: aim 3: assess patient and operative factors that contribute to prolonged or greater than expected opioid usage. objectives: the factors contributing to prolonged patient use of opioids and need for repeated refills are poorly understood. an analysis of factors contributing to prolonged opioid use and a determination of baseline opioid use rates would allow hand surgeons to have a better understanding of factors that may place a patient at risk or to identify when patients are exceeding the typical requirements for opioids. identification of these patients may allow for increased counseling, referral to a pain specialist, or increased surveillance. details of the operative procedure and typical narcotic requirements will guide providers in prescribing more limited opioid prescriptions appropriate to an individual procedure with few to no refills authorized. outcome variables and analysis: patients will be separated into groups based on whether they used over 80% of their opioid prescription or if they requested a refill of their opioid prescription within the two week study period. a univariate analysis of patient demographic factors and operative details will identify factors that are potentially associated with higher rates of opioid consumption following surgery. chi square tests will be performed for categorical variables and student's t-tests will be used for continuous variables. binary logistic regression will then be performed using variables identified in the univariate screen in order to identify independent factors contributing to a higher number of opioids used after surgery.
