RESUMEN

Brief motivational interventions (BMIs) are usually effective for reducing alcohol use and consequences in primary care settings. We examined readiness to change drinking as a mediator of the effects of BMI on alcohol-related consequences. Participants were randomized into three conditions: (a) standard care plus assessment (SC), (b) SC plus BMI (BI), and (c) BI plus a booster session (BIB). At 12-month follow-up BIB patients had significantly reduced alcohol consequences more than had SC patients. Patients receiving BI or BIB maintained higher readiness scores 3 months after treatment than did patients receiving SC. However, readiness mediated treatment effects only for those highly motivated to change prior to the intervention but not for those with low pre-intervention motivation. BI and BIB for these patients decreased alcohol consequences in part because they enhanced and maintained readiness for those highly motivated prior to the intervention, but not for those with low motivation. Results are opposite of what would be expected from MI theory. An alternative explanation is offered as to why this finding occurred with this opportunistically recruited Emergency Department patient population.

RESUMEN

CONTEXT: Rural and frontier states are significantly affected by substance abuse and poverty. The high rate of substance abuse coupled with high levels of dependence on state-funded treatment systems places a burden on rural treatment systems and makes resource allocation a central planning issue. PURPOSE: The goal of this study was to combine substance abuse treatment need data with organizational readiness to change data to create a rank-ordered listing of residential treatment providers to answer the following questions: Do program priority rankings change when organizational readiness to change is included in a need-based resource allocation algorithm? METHODS: Three methodological procedures were used to determine program priority rankings among 14 residential adolescent treatment programs in 8 Wyoming counties: (1) a social indicators analysis of crime data, (2) synthetic estimates of substance abuse treatment need, and (3) analysis of organizational change data from the directors and staff at adolescent residential treatment programs. FINDINGS: Program need rankings based on crime data and synthetic estimates of substance abuse treatment need shifted when organizational readiness to change data was added to the algorithm. CONCLUSIONS: There is much to be gained from considering organizational readiness to change when selecting programs for funding. It plays a central role in the successful diffusion of evidence-based practices within and among programs. Including this measure in the resource allocation process can help planners identify programs that will be more apt to adopt a best practice. This is critical for making decisions about where to allocate scarce treatment resources.

RESUMEN

OBJECTIVE: To determine whether brief, focal pretreatment of children's skin with low-frequency ultrasound followed by a 5-minute application of a 4% lidocaine topical anesthetic decreases the pain of intravenous (IV) catheter placement. METHODS: A randomized, double-blind, placebo-controlled trial enrolling children 8 to 18 years of age undergoing IV placement as part of their care in a pediatric emergency department. Thirty-eight children received pretreatment followed by 5-minute application of a topical anesthetic. Thirty-nine children received pretreatment followed by 5-minute application of a placebo cream. Children and parents rated the pain associated with IV placement using the visual analog scale (VAS). RESULTS: There were no significant differences in demographics between the 2 groups. Children in the treatment group had significantly lower VAS scores (mean, 2.29) than children in the control group (mean, 3.23) (P = 0.023; 95% confidence interval of the mean difference, -1.87 to -0.02). The parents' VAS scores of the child's pain were also lower for the treatment group (mean, 2.47 vs 3.39; P = 0.038; confidence interval, -1.97 to 0.11). CONCLUSIONS: Visual analog scale scores measuring children's pain and parents' perception of the child's pain were lower in those who were pretreated with brief focal ultrasound and 5 minutes of 4% lidocaine cream when compared with those pretreated with ultrasound and placebo.

RESUMEN

OBJECTIVE: Although the Short Index of Problems (SIP) is often used, little is known about the psychometric properties of the SIP in special populations. The present study seeks to determine the following: (1) whether it is possible to substitute items to enhance the psychometric properties of the SIP and (2) whether the SIP, or improved scale, is as sensitive as the Drinker Inventory of Consequences (DrInC) to assess intervention effectiveness. METHOD: The sample consisted of 404 injured patients who were treated in the Emergency Department (ED) of a major teaching hospital that serves southern New England. Three approaches were used to guide development of the 3-month SIP-R, the potential alternative to the SIP. Cronbach's alpha assessed intrascale reliability; hierarchical multiple regression assessed construct validity; performance of the scales assessing intervention change were compared to the total 3-month DrInC as a function of intervention using analysis of covariance (ANCOVA). RESULTS: There was no evidence that changing the current SIP items will significantly improve performance. The 3-month SIP performed as well as the 3-month DrInC-2R in predicting 12-month DrInC scores and in determining intervention change at 12 months. Of the 45 DrInC items, 31 also predicted a difference across intervention groups. CONCLUSIONS: These results suggest there is no advantage to changing the current SIP items. The 3-month SIP is a psychometrically sound measure for assessing consequences of alcohol consumption in an ED sample and is almost as sensitive to intervention change as the full DrInC.

RESUMEN

OBJECTIVES: Physicians and nurses in the emergency department rarely use topical anesthesia when starting intravenous (IV) lines because of time constraints and lack of data on patients' perception of the pain associated with this procedure. Ultrasound pretreatment of skin increases permeation rates of hydrophobic topical medications, including topical lidocaine. The objective of this study was to demonstrate that ultrasound treatment followed by brief application of topical anesthetic decreases the patients' perception of the pain of IV cannulation. METHODS: This was a randomized, controlled, prospective trial performed in a university hospital emergency department. Eighty-seven consecutive English-speaking, subcritically injured or ill adult patients able to give consent who were receiving an IV line as part of their care were enrolled. The intervention was a brief ultrasound treatment using the SonoPrep (Sontra Medical Corp., Franklin, MA) therapeutic ultrasound device (frequency, 53-56 kHz) followed by 5 minutes of 4% liposomal lidocaine cream and standard-care IV cannulation, or standard care alone. Participants rated their pain on a visual analog scale. Researchers assessed the site after IV insertion and 20-36 hours later. The primary outcome was participants' subjective pain score, and the secondary outcome was site skin irritation. RESULTS: The ultrasound group reported significantly less pain (p<0.001), with 80% of treated participants reporting pain scores

RESUMEN

Many published clinical trials have less than adequate follow-up. When conducting a clinical trial, researchers attempt to minimize data loss; however, some data may not be collected, particularly when subjects are lost to follow-up. Careful planning of research protocols, including comprehensive initial data collection, identification of locators, flexible scheduling, systematic subject tracking, monitoring subject loss, and systematically approaching problem cases can ensure high follow-up rates. This article presents a compendium of techniques and procedures that researchers can use to enhance follow-up and address attrition in their studies. Finally, this article outlines statistical techniques that can be used to address the effects of missing data, particularly when patients are lost to follow-up.

RESUMEN

OBJECTIVES: The purpose of this paper is to better understand marijuana use among injured problem drinkers in the emergency department (ED). The specific objectives are: 1) to assess the prevalence of marijuana use; 2) to identify factors associated with marijuana use; 3) to determine whether prior injury is associated with marijuana use; and 4) to determine whether marijuana-using problem drinkers want to change behaviors. METHODS: The authors conducted a post-hoc analysis on data obtained prospectively. Subjects had injury and problem drinking: either measurable alcohol level (blood alcohol concentration, BAC), report of drinking, or an Alcohol Use Disorders Identification Test (AUDIT) score of > or =8. The study was conducted on weekend nights; 3,776 injured ED patients were screened, 383 refused, 578 were enrolled, and 433 had complete data. RESULTS: Of the 433 subjects, 48.3% reported using marijuana in the three months prior. Marijuana-using problem drinkers had more hazardous drinking, higher AUDIT scores (14.0 vs. 11.4, p < 0.001), and higher risk-taking scores (12.4 vs. 10.1, p < 0.001). More used other drugs (69.7% vs. 30.3%, p < 0.001). In regression analyses, marijuana use remained an independent predictor of prior injury (OR = 2.16, 95% CI = 1.25 to 3.75), particularly prior alcohol-related (OR = 2.26, 95% CI = 1.45 to 3.53) and motor-vehicle-related (OR = 1.69, 95% CI = 1.03 to 2.79) injury. Readiness-to-change scores were similar (4.14 vs. 4.22, p = 0.21) between users and nonusers. CONCLUSIONS: Marijuana use among injured problem drinkers is prevalent. Their risk of prior injury is increased. Counseling for alcohol and injury should address marijuana use.
