Objective: To quantify the frequency, cost, and characteristics associated with emergency department (ED) visits that are related to methamphetamine use.Methods: This was a prospective observational study. The authors performed a training program for ED clinicians on the acute and chronic effects of methamphetamine and the signs of methamphetamine abuse. A standardized two question survey was administered to clinicians concerning the relationship between the ED visit and the patient's methamphetamine use. The survey was embedded in the patient tracking system and was required for all ED patients before disposition. Survey results were merged with administrative data on demographics, diagnosis, disposition, and charges. Univariate analyses were used to determine patient characteristics associated with methamphetamine-related ED visits. Results:The authors examined 15,038 ED visits over a 20-week period from February 2006 to June 2006. There were a total of 353 methamphetamine-related visits, for an average of 17.65 visits per week (2.4% of all visits). Hospital charges for methamphetamine-related ED visits averaged $133,181 per week, for an estimated total of $6.9 M in annual charges. Methamphetamine-related ED patients were more likely to be male (odds ratio [OR] 1.6, 95% confidence interval [CI] = 1.30 to 2.01), white (OR 1.8, 95% CI = 1.38 to 2.29), and uninsured (OR 3.2, 95% CI = 2.21 to 4.69). The top four medical conditions associated with methamphetamine-related visits were mental health (18.7%), trauma (18.4%), skin infections (11.1%), and dental diagnoses (9.6%).Conclusions: Methamphetamine abuse accounts for a modest but substantial proportion of ED utilization and hospital cost. Methamphetamine-related ED visits are most commonly related to mental illness, trauma, skin, and dental-related problems.ACADEMIC EMERGENCY MEDICINE 2008; 15:23-31 ª
Hydrogen sulfide toxicity is uncommon, but potentially deadly. Toxicity is predominantly in new workers and co-worker fatalities occur in a significant minority of cases. Proper training and education on the warning signs of hydrogen sulfide toxicity may help reduce worker fatalities.
The American College of Medical Toxicology established the Toxicology Investigators Consortium (ToxIC) Case Registry in 2010. The Registry contains all medical toxicology consultations performed at participating sites. The Registry has continued to grow since its inception, and as of December 31, 2015, contains 43,099 cases. This is the sixth annual report of the ToxIC Registry, summarizing the additional 8115 cases entered in 2015. Cases were identified by a query of the Registry for all cases entered between January 1 and December 31, 2015. Specific data reviewed for analysis included demographics (age, race, gender), source of consultation, reason for consultation, agents and agent classes involved in exposures, signs, symptoms, clinical findings, fatalities, and treatment. By the end of 2015, there were 50 active sites, consisting of 101 separate health-care facilities; 51.2 % of cases involved females. Adults between the ages of 19 and 65 made up the majority (64.2 %) of Registry cases. Caucasian race was the most commonly reported (55.6 %); 9.6 % of cases were identified as Hispanic ethnicity. Inpatient and emergency department referrals were by far the most common referral sources (92.9 %). Intentional pharmaceutical exposures remained the most frequent reason for consultation, making up 52.3 % of cases. Of these intentional pharmaceutical exposures, 69 % represented an attempt at self-harm, and 85.6 % of these were a suicide attempt. Nonopioid analgesics, sedative-hypnotics, and antidepressant agents were the most commonly reported agent classes in 2015. Almost one-third of Registry cases involved a diagnosed toxidrome (32.8 %), with a sedative-hypnotic toxidrome being the most frequently described. Significant vital sign abnormalities were recorded in 25.3 % of cases. There were 98 fatalities reported in the Registry (1.2 %). Adverse drug reactions were reported in 4.3 % of cases. Toxicological treatment was given in 65.3 % of cases, with 33.0 % receiving specific antidotal therapy. Exposure characteristics and trends overall were similar to prior years. While treatment interventions were required in the majority of cases, fatalities were rare.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
