Hospitalizations for Poisoning by Prescription Opioids, Sedatives, and Tranquilizers

BACKGROUND Unintentional poisoning deaths have been increasing dramatically over the past decade, and the majority of this increase has resulted from overdoses of specific prescription drugs. Despite this trend, there are limited existing data examining hospitalizations for poisonings, both unintentional and intentional, associated with prescription drugs. A better understanding of these hospitalizations may help identify high-risk populations in need of intervention to prevent subsequent mortality. PURPOSE This article aims to describe the incidence and characteristics of hospitalizations resulting from poisoning by prescription opioids, sedatives, and tranquilizers in the U.S. from 1999 to 2006 and make comparisons to hospitalizations for all other poisonings during this time period. METHODS Hospitalizations for poisonings were selected from the Nationwide Inpatient Sample (NIS), a stratified, representative sample of approximately 8 million hospitalizations each year, according to the principal discharge diagnosis. Intentionality of the poisoning was determined by external cause of injury codes. SAS callable SUDAAN software was used to calculate weighted estimates of poisoning hospitalizations by type and intentionality. Demographic and clinical characteristics of poisoning cohorts were compared. Data were analyzed in 2009. RESULTS From 1999 to 2006, U.S. hospitalizations for poisoning by prescription opioids, sedatives, and tranquilizers increased a total of 65%. This increase was double the increase observed in hospitalizations for poisoning by other drugs and substances. The largest increase in the number of hospitalized cases over the 7-year period was seen for poisonings by benzodiazepines, whereas the largest percentage increase was observed for methadone (400%). In comparison to patients hospitalized for poisoning from other substances, those hospitalized for prescription opioids, sedatives, and tranquilizers were more likely to be women, aged >34 years, and to present to a rural or urban nonteaching hospital. CONCLUSIONS Prescription opioids, sedatives, and tranquilizers are an increasing cause of hospitalization. The hospital admission provides an opportunity to better understand the contextual factors contributing to these cases, which may aid in the development of targeted prevention strategies.

Systems modeling in support of evidence-based disaster planning for rural areas

Abstract The objective of this communication is to introduce a conceptual framework for a study that applies a rigorous systems approach to rural disaster preparedness and planning. System Dynamics is a well-established computer-based simulation modeling methodology for analyzing complex social systems that are difficult to change and predict. This approach has been applied for decades to a wide variety of issues of healthcare and other types of service capacity and delivery, and more recently, to some issues of disaster planning and mitigation. The study will use the System Dynamics approach to create computer simulation models as “what-if” tools for disaster preparedness planners. We have recently applied the approach to the issue of hospital surge capacity, and have reached some preliminary conclusions – for example, on the question of where in the hospital to place supplementary nursing staff during a severe infectious disease outbreak—some of which we had not expected. Other hospital disaster preparedness issues well suited to System Dynamics analysis include sustaining employee competence and reducing turnover, coordination of medical care and public health resources, and hospital coordination with the wider community to address mass casualties. The approach may also be applied to preparedness issues for agencies other than hospitals, and could help to improve the interactions among all agencies represented in a communitys local emergency planning committee. The simulation models will support an evidence-based approach to rural disaster planning, helping to tie empirical data to decision-making. Disaster planners will be able to simulate a wide variety of scenarios, learn responses to each and develop principles or best practices that apply to a broad spectrum of disaster scenarios. These skills and insights would improve public health practice and be of particular use in the promotion of injury and disease prevention programs and practices.

Comparison of domestic violence screening methods: a pilot study.

STUDY OBJECTIVE Previous studies have indicated a number of barriers to screening for domestic violence (DV) in an emergency department setting. These barriers result in inconsistencies which determine who is screened as well as the content and quality of the information obtained, and if uncontrolled they are likely to affect measurements of DV incidence in ED populations. The objectives of this project were to design a screening tool that circumvented these barriers and sources of error; to assess whether such an alternative method of screening for DV was acceptable to our patients; and to determine whether the alternative and traditional methods of screening for DV would yield comparable results. Our hypotheses were that the alternative screening tool would be acceptable to our patients and that no significant differences would be found between the two methods. METHODS The study took place in a rural, university-affiliated ED with approximately 36,000 annual patient visits. The study population consisted of 186 women older than 18 years of age who were treated by one designated physician. Approximately half of these subjects were screened for DV in a face-to-face interview. The other half listened to a tape-recorded questionnaire and recorded their responses on a coded answer sheet. RESULTS There were 175 completed screenings. The average age of all respondents was 34 years, and 90 (51%) indicated a cumulative lifetime experience of DV of some sort. Overall, 3% of the respondents indicated they were in the ED for injuries received as a result of DV. No significant differences were found between the two methods of screening for DV on any measurement, including refusals. No problems hearing the tape or understanding the instructions were reported. CONCLUSION These results indicate that the alternative method of employing a recorded questionnaire was no less effective than the best efforts of a designated and conscientious physician. As a means of quickly assessing the prevalence of DV in an ED setting, we find much to recommend such an approach.

Screening and brief intervention for alcohol problems among college students treated in a university hospital emergency department.

Abstract The authors evaluated a protocol to screen and provide brief interventions for alcohol problems to college students treated at a university hospital emergency department (ED). Of 2,372 drinkers they approached, 87% gave informed consent. Of those, 54% screened positive for alcohol problems (Alcohol Use Disorders Identification Test score < 6). One half to two thirds of the students who screened positive drank 2 to 3 times a week, drank 7 or more drinks per typical drinking day, or had experienced alcohol dependence symptoms within the past year. Ninety-six percent of screen-positive students accepted counseling during their ED visit. Three quarters of those questioned at 3-month follow-up reported that counseling had been helpful and that they had decreased their alcohol consumption. The prevalence of alcohol problems, high rates of informed consent and acceptance of counseling, and improved outcomes suggest that the ED is an appropriate venue for engaging students at high risk for alcohol problems.

Rural–Urban Differences in Injury Hospitalizations in the U.S., 2004

BACKGROUND Despite prior research demonstrating higher injury-mortality rates among rural populations, few studies have examined the differences in nonfatal injury risk between rural and urban populations. The objective of this study was to compare injury-hospitalization rates between rural and urban populations using population-based national estimates derived from patient-encounter data. METHODS A cross-sectional analysis of the 2004 Nationwide Inpatient Sample was conducted in 2007. Rural-urban classifications were determined based on residence. SUDAAN software and U.S. Census population estimates were used to calculate nationally representative injury-hospitalization rates. Injury rates between rural and urban categories were compared with rate ratios and 95% CIs. RESULTS An estimated 1.9 million (95% CI=1,800,250-1,997,801) injury-related hospitalizations were identified. Overall, injury-hospitalization rates generally increased with increasing rurality; rates were 27% higher in large rural counties (95% CI=10%, 44%) and 35% higher in small rural counties (95% CI=16%, 55%). While hospitalization rates for assaults were highest in large urban counties, the rates for unintentional injuries from motor vehicle traffic, falls, and poisonings were higher in rural populations. Rates for self-inflicted injuries from poisonings, cuttings, and firearms were higher in rural counties. The total estimated hospital charges for injuries were more than

Injury Recidivism in a Rural ED

50 billion. On a per-capita basis, hospital charges were highest for rural populations. CONCLUSIONS These findings highlight the substantial burden imposed by injury on the U.S. population and the significantly increased risk for those residing in rural locations. Prevention and intervention efforts in rural areas should be expanded and should focus on risk factors unique to these populations.

The Emergency Department Log as a Simple Injury-Surveillance Tool

STUDY OBJECTIVE To determine the degree of injury recidivism in our ED population and to identify indicators of injury recidivism. METHODS We conducted a retrospective review in a university-affiliated department of emergency medicine. The study participants were patients who presented for treatment of an injury. An injury recidivist was defined as a patient who presented for treatment of two or more unique injuries during the 1-year study period. The injured population was divided into three categories: (1) those with a single injury visit, (2) those with two to three injury visits, and (3) those with four or more injury visits. Demographics, mechanism of injury, and outcome data were collected and comparative analyses performed. RESULTS Of the 37,360 ED patient visits, 12,075 were injury related. Of the injury visit load, 2,838 of the 12,075 (24%) were injury recidivists. Of injured patients, 1,239 of 10,476 (12%) were recidivists. The sex distribution was similar among the groups, but the mean age decreased as the degree of recidivism increased. The degree of recidivism was higher for patients with Medicaid and for those who were uninsured. Lower mean medical charges per visit were found with increasing degree of recidivism, but the average total charges per patient increased with increasing degree of recidivism. Increasing degree of recidivism was associated with decreasing incidence of transportation-related injury but increased incidence of overexertion or intentional injuries. CONCLUSION A small group of patients account for a significant proportion of ED injury visits. In comparison with injury patients seen once during the year, recidivists represent a younger population of lower socioeconomic status, and they are at increased risk of intentional injury.

Matched analysis of parent's and children's attitudes and practices towards motor vehicle and bicycle safety: an important information gap

STUDY OBJECTIVE To describe the development of an injury-surveillance system based on the emergency department log. SETTING An ED with 40,000 visits annually, tertiary care center. PARTICIPANTS All patients to our ED during a 6-month period. ED logs are used to collect basic information such as demographics, chief complaint, mode of arrival, and disposition. Our log was modified for collection of injury-related information such as whether the ED visit was because of an injury and, if so, the mechanism of injury. A list of 16 mechanism-of-injury codes was developed on the basis of review of existing literature and on a 1-month review of injuries in our population. The ED log data were entered into a database, and descriptive analysis was performed. RESULTS A list of mechanisms of injury was developed that, when implemented, was successful in coding 93% of injured patients in our ED population. The expansion of the ED log for collection of injury data required minimal training and cost. An example of the data obtained is presented to demonstrate the type of information available. Of the 18,742 patients, the ED log identified 5,067 patients (27%) as having been injured. Most were male (2,972 of 5,067 [59%]), and most were between 15 and 40 years of age (2,857 of 5,067 [61%]). Common mechanisms of injury included falls (907 of 5,067 [19%]), transportation (706 of 5,067 [15%]), cuts or punctures (332 of 5,067 [7%]), sports (323 of 5,067 [7%]), and assaults (245 of 5,067 [5%]). CONCLUSION With minimal training and cost, the ED log can be adapted for collection of injury data on all patients seen in the ED.

Realities of rural emergency medical services disaster preparedness

The purpose of this study was to compare parents’ and children’s attitudes and habits towards use of bicycle helmets and car seat belts. We hypothesized that parental perception of their children’s safety practices did not reflect actual behavior and further, that parental practices, rather than their beliefs about a particular safety practice, have a greater affect on their child’s risk-taking behavior. The study population consisted of children in grades four and five and their parents/guardians. Participation in the cross-sectional study was voluntary and confidential anonymous questionnaires were used. In separate and independent surveys, children and parents were questioned in parallel about their knowledge, habits and attitudes toward bicycle helmet use and car safety practices. In the study, 731 students participated with 329 matched child-parent pairs. Ninety-five percent of the children own bicycles and 88% have helmets. Seventy percent of parents report their child always wears a helmet, while only 51% of children report always wearing one (p < 0.05). One-fifth of the children never wear a helmet, whereas parents think only 4% of their children never use one (p < 0.05). Parents report their children wear seat belts 92% of the time while 30% of children report not wearing one. Thirty-eight percent of children ride bicycles with their parents and wear their helmets more often than those who do not ride with their parents (p < 0.05). Parents who always wear a seat belt are more likely to have children who sit in the back seat and wear a seat belt (p < 0.05). Parents’ perceptions of their children’s safety practices may not be accurate and their actions do affect their children’s. Injury prevention programs that target both parents and children may have a greater impact on reducing risk-taking behaviors than working with each group in isolation.

Development of an Emergency Department—Based Injury Surveillance System

INTRODUCTION Disaster preparedness is an area of major concern for the medical community that has been reinforced by recent world events. The emergency healthcare system must respond to all types of disasters, whether the incidents occur in urban or rural settings. Although the barriers and challenges are different in the rural setting, common areas of preparedness must be explored. PROBLEM This study sought to answer several questions, including: (1) What are rural emergency medical services (EMS) organizations training for, compared to what they actually have seen during the last two years?; (2) What scale and types of events do they believe they are prepared to cope with?; and (3) What do they feel are priority areas for training and preparedness? METHODS Data were gathered through a multi-region survey of 1801 EMS organizations in the US to describe EMS response experiences during specific incidents as well as the frequency with which these events occur. Respondents were asked a number of questions about local priorities. RESULTS A total of 768 completed surveys were returned (43%). Over the past few years, training for commonly occurring types of crises and emergencies has declined in favor of terrorism preparedness. Many rural EMS organizations reported that events with 10 or fewer victims would overload them. Low priority was placed on interacting with other non-EMS disaster response agencies, and high priority was placed on basic staff training and retention. CONCLUSION Maintaining viable, rural, emergency response capabilities and developing a community-wide response to natural or man-made events is crucial to mitigate long-term effects of disasters on a local healthcare system. The assessment of preparedness activities accomplished in this study will help to identify common themes to better prioritize preparedness activities and maximize the response capabilities of an EMS organization.
