Interpreting the National Hospital Ambulatory Medical Care Survey: United States Emergency Department Opioid Prescribing, 2006-2010.

ABSTRACT: Prescription opioid overdoses are a leading cause of death in the United States. Emergency departments (EDs) are potentially high-risk environments for doctor shopping and diversion. The hypothesis was that opioid prescribing rates from the ED have increased over time.The authors analyzed data on ED discharges from the 2006 through 2010 NHAMCS, a probability sample of all U.S. EDs. The outcome was documentation of an opioid prescription on discharge. The primary independent predictor was time. Covariates included severity of pain, a pain-related discharge diagnosis, age, sex, race, payer, hospital ownership, and geographic location of hospital. Up to three discharge diagnoses were available in NHAMCS to identify "pain-related" (e.g., back pain, fracture, dental/jaw pain, nephrolithiasis) ED visits. Multivariate logistic regression was performed to assess the independent associations between opioid prescribing and predictors. All analyses incorporated NHAMCS survey weights, and all results are presented as national estimates.Opioids were prescribed for 18.7% (95% confidence interval = 17.7% to 19.7%) of all ED discharges, representing 18.8 million prescriptions per year. There were no significant temporal trends in opioid prescribing overall (adjusted p = 0.93). Pain-related discharge diagnoses that received the top three highest proportion of opioids prescriptions included nephrolithiasis (62.1%), neck pain (51.6%), and dental/jaw pain (49.7%). A pain-related discharge diagnosis, non-Hispanic white race, older age, male sex, uninsured status, and Western region were positively associated with opioid prescribing (p < 0.05).No temporal trend toward increased prescribing from 2006 to 2012 was found. These results suggest that problems with opioid overprescribing are multifactorial and not solely rooted in the ED.

Project description:IntroductionNational guidelines suggest that most skin abscesses do not require antibiotics, and that cellulitis antibiotics should target streptococci, not community-associated MRSA (CA-MRSA). The objective of this study is to describe antimicrobial treatment of skin infections in U.S. emergency departments (EDs) and analyze potential quality measures.MethodsThe National Hospital Ambulatory Medical Care Survey (NHAMCS) is a 4-stage probability sample of all non-federal U.S. ED visits. In 2007 NHAMCS started recording whether incision and drainage was performed at ED visits. We conducted a retrospective analysis, pooling 2007-2010 data, identified skin infections using diagnostic codes, and identified abscesses by performance of incision and drainage. We generated national estimates and 95% confidence intervals using weighted analyses; quantified frequencies and proportions; and evaluated antibiotic prescribing practices. We evaluated 4 parameters that might serve as quality measures of antibiotic stewardship, and present 2 of them as potentially robust enough for implementation.ResultsOf all ED visits, 3.2% (95% confidence interval 3.1-3.4%) were for skin infection, and 2.7% (2.6-2.9%) were first visits for skin infection, with no increase over time (p=0.80). However, anti-CA-MRSA antibiotic use increased, from 61% (56-66%) to 74% (71-78%) of antibiotic regimens (p<0.001). Twenty-two percent of visits were for abscess, with a non-significant increase (p=0.06). Potential quality measures: Among discharged abscess patients, 87% were prescribed antibiotics (84-90%, overuse). Among antibiotic regimens for abscess patients, 84% included anti-CA-MRSA agents (81-89%, underuse).ConclusionFrom 2007-2010, use of anti-CA-MRSA agents for skin infections increased significantly, despite stable visit frequencies. Antibiotics were over-used for discharged abscess cases, and CA-MRSA-active antibiotics were underused among regimens when antibiotics were used for abscess. [West J Emerg Med. 2014;15(3):282-289.].

Project description:STUDY OBJECTIVE:We assess whether an automated prescription drug monitoring program intervention in emergency department (ED) settings is associated with reductions in opioid prescribing and quantities. METHODS:We performed a retrospective cohort study of ED visits by Medicaid beneficiaries. We assessed the staggered implementation (pre-post) of automated prescription drug monitoring program queries at 86 EDs in Washington State from January 1, 2013, to September 30, 2015. The outcomes included any opioid prescribed within 1 day of the index ED visit and total dispensed morphine milligram equivalents. The exposure was the automated prescription drug monitoring program query intervention. We assessed program effects stratified by previous high-risk opioid use. We performed multiple sensitivity analyses, including restriction to pain-related visits, restriction to visits with a confirmed prescription drug monitoring program query, and assessment of 6 specific opioid high-risk indicators. RESULTS:The study included 1,187,237 qualifying ED visits (898,162 preintervention; 289,075 postintervention). Compared with the preintervention period, automated prescription drug monitoring program queries were not significantly associated with reductions in the proportion of visits with opioid prescribing (5.8 per 1,000 encounters; 95% confidence interval [CI] -0.11 to 11.8) or the amount of prescribed morphine milligram equivalents (difference 2.66; 95% CI -0.15 to 5.48). There was no evidence of selective reduction in patients with previous high-risk opioid use (1.2 per 1,000 encounters, 95% CI -9.5 to 12.0; morphine milligram equivalents 1.22, 95% CI -3.39 to 5.82). The lack of a selective reduction in high-risk patients was robust to all sensitivity analyses. CONCLUSION:An automated prescription drug monitoring program query intervention was not associated with reductions in ED opioid prescribing or quantities, even in patients with previous high-risk opioid use.
