Frequency of heavy episodic drinking among nonfatal injury patients attending an emergency room.

This study investigated the relationship between frequency of heavy episodic drinking and nonfatal injury in four categories: environment, external cause, diagnosis, and activity at the time of injury. Data were collected over 18 months at the emergency room facility of a Swedish hospital. Injury patients aged 18-70 years answered an alcohol screening questionnaire. Heavy episodic drinking was measured as drinking six glasses (72 g alcohol) or more per occasion, for both males and females. A total of 2211 patients were enrolled in the study (79.5% completion rate). Demographic and drinking characteristics for the patients were compared to those of the general population, data for which were derived from a population-based survey. The proportion of people who reported heavy episodic drinking once a month or more was nearly twice as large among the injury patients as in the general population. However, age and sex outweighed heavy episodic drinking as risk factors for most injury types. There were 11 significant associations between frequency of heavy episodic drinking and injury types in the four injury categories, yet no linear trends of increased likelihood of injury with increased frequency of heavy episodic drinking could be discerned.

Effectiveness of community-based injury prevention. Long-term injury rate levels, changes, and trends for 14 Swedish WHO-designated Safe Communities.

This study investigates the injury rate levels, changes, and trends between 1987 and 2002 for the 14 Swedish municipalities designated as WHO Safe Communities. The injury rate was defined as the number of injured patients discharged from hospital per 1000 persons. Injury rates were age standardised. Each municipality was compared with its respective municipality group, according to a classification of Sweden's 288 municipalities into nine groups based on numerous structural parameters. The average injury rate levels for the 14 WHO-designated Safe Community municipalities ranged from 11.54 to 19.09 per 1000 population during the study period, which was defined as the time period during which a municipality's injury prevention program has been operational. Eleven of 14 municipalities had higher levels than their corresponding municipality groups. Five of the 14 municipalities "outperformed" their respective municipality groups and achieved a greater relative injury rate decrease during the study period. The trends for the 14 municipalities in relation to their municipality groups showed an inconsistent pattern, with only four municipalities exhibiting overall favourable trends for the study period.

Effectiveness of strategies to implement brief alcohol intervention in primary healthcare. A systematic review.

OBJECTIVE: To review systematically the available literature on implementation of brief alcohol interventions in primary healthcare in order to determine the effectiveness of the implementation efforts by the health are providers. KEY QUESTION: To what extent have the efforts to implement brief alcohol interventions in primary healthcare environments been successful? METHOD: Literature search from Medline, Cinahl, PsychLIT, Cochrane. SETTING: Primary healthcare. MATERIAL: A total of 11 studies encompassing 921 GPs, 266 nurses, 88 medical students, and 44 "non-physicians" from Europe, the USA, and Australia. MAIN OUTCOME MEASURES: Material utilization, screening, and brief intervention rates. ANSWER: Intervention effectiveness (material utilization, screening, and brief intervention rates) generally increased with the intensity of the intervention effort, i.e. the amount of training and/or support provided. Nevertheless, the overall effectiveness was rather modest. However, the studies examined were too heterogeneous, not scientifically rigorous enough, and applied too brief follow-up times to provide conclusive answers.

Strategies and goals of community-based injury prevention programmes--a mixed-methods study of 25 Scandinavian WHO Safe Communities.

Documentation and analysis of prevention goals and interventions employed by community-based injury prevention programmes is vital to advance the knowledge and understanding of synergistic multi-strategy injury prevention programmes. This study examined the goals and interventions of 25 Scandinavian community-based injury prevention programmes in WHO-designated Safe Communities. Collection and analysis of quantitative data from survey questionnaires to the programme coordinators was followed by collection and analysis of qualitative data from structured interviews with programme coordinators from eight of the programmes. The results demonstrated that the programmes under study predominantly relied on "intuitive" and subjective methods for selecting interventions. The programmes largely failed to transform injury surveillance data into information and knowledge that could prioritize community safety strategies and measures, due to insufficient time and personnel resources. The results demonstrated the importance of combining passive approaches with active interventions. Educational efforts were considered essential to the programmes. The programmes preferred to rely on broadly stated goals rather than specific objectives.

Economic analysis of injury prevention--applying results and methodologies from cost-of-injury studies.

Injuries pose an economic problem of immense proportion to communities in every society. The economic burden from injuries can be quantified through cost-of-injury studies, using techniques adopted from cost-of-illness research. This study explores the feasibility of applying results and methodologies from existing cost-of-injury studies in economic analyses of injury prevention interventions and programmes. The literature on cost-of-injury studies and economic appraisals of injury prevention efforts was examined to elicit studies that calculated injury costs. Studies were accepted for inclusion if they included an analysis of the costs of all injuries occurring in a geographical area (community, region or country) during a specific time period, employed a societal perspective and an incidence-based costing approach and were conducted in industrialized countries. There were 12 studies that met the inclusion criteria. The average total cost per injury case was USD $3536, while the average share of indirect to total cost per injury case was 71%. However, the cost figures showed wide variation across the studies. Based on the limited similarity of findings from the studies, it was concluded that it is not feasible to apply results and methodologies from existing cost-of-injury studies. The cost estimators described in this study could possibly be adapted for use as reference points in economic analyses of existing programmes, but any other uses should be approached with caution. Locally obtained data are needed for reliable economic analyses of injury prevention interventions and programmes.

Evaluation of community-based injury prevention programmes: methodological issues and challenges.

The evaluation of comprehensive community-based injury prevention programmes is complex and poses many methodological challenges. There is little consensus in contemporary literature about the most appropriate methods of evaluating these programmes. This study employed a systematic literature review to examine evaluations of 16 community-based injury prevention programmes with regard to key methodological issues and challenges. Three aspects of the evaluated programmes were analysed: assessed elements (context, structure, process, impact, and outcome); study design; and methodological issues addressed. The results showed that context, structure and process assessments were the most neglected aspects of the evaluation studies. The programmes were typically described with minimal discussion of how the context may have influenced the effectiveness. The process (activities) was described rather than evaluated against appropriate standards of comparisons. Impact evaluations adhered more closely to documented guidelines, but half of the evaluations did not include impact variables. Outcome evaluations focused on injury incidence. Most evaluations employed some qualitative methods, but the vast majority of methods used were quantitative. This study indicated that the quasi-experimental study design has become an accepted norm for the evaluation of community-based injury prevention programmes. Most of the evaluations contained explicit details of the methodology used and of the choices related to the methodology. While threats to internal validity were identified in most studies, problems related to external validity and construct validity were largely overlooked by the evaluators.

Factors associated with injuries occurring aboard vessels in Alaska: differences between residents and nonresidents.

BACKGROUND: Over the past decade, visitors to Alaska have spent increasing amounts of time engaged in water-based recreational activities aboard vessels of various sizes. Serious vessel-related injuries to travelers in Alaska involve not only medical care from unfamiliar health care providers and facilities but also entail the loss of vacation time and the need for injured travelers to return to their homes under less than optimal traveling conditions. METHODS: This study employed a retrospective, case-comparison analysis to identify differences in factors associated with recreational injuries acquired aboard watercraft that resulted in hospitalizations of residents and nonresidents of Alaska during 1991 to 2000. Tests of proportions were conducted to elucidate differences in demographic characteristics and injury precursors between the two subgroups. Specific injury outcomes were then tested for significance using odds ratios. RESULTS: Alaska residents and nonresidents demonstrated significant differences for both demographic factors and factors describing events leading to injuries, and for injury outcomes. Nonresidents were more likely to be 65 years or older, female, and aboard cruise ships when injuries occurred. Nonresidents were more likely to suffer fracture injuries, to suffer injuries with Abbreviated Injury Scores greater than 2, to experience posthospital discharges to sites other than their homes, and to experience postinjury disabilities. CONCLUSIONS: Alaska residents and nonresidents in this study showed significant differences in demographics, precipitating events, and injury outcomes. The findings lend support for targeted safety promotion programs.
