INTRODUCTION: While several population-based studies have documented behavioral health disturbances following terrorist attacks, a number of mental health service utilization analyses present conflicting conclusions. PURPOSE: The purpose of this study was to determine if mental health service utilization increased following a terrorist attack by assessing changes in psychoactive drug prescription rates. METHODS: The rate of selective serotonin reuptake inhibitor (SSRI) prescriptions was measured among New York State Medicaid enrollees before and after the terrorist attacks of 11 September 2001. The association between geographic proximity to the events and changes in the rate of SSRI prescriptions around 11 September 2001 was assessed. RESULTS: From September to December 2001, among individuals residing within three miles of the World Trade Center site, there was an 18.2% increase in the SSRI prescription rate compared to the previous eight-month period (p = 0.0011). While there was a 9.3% increase for non-New York City residents, this change was not statistically significant (p = 0.74). CONCLUSIONS: There was a quantifiable increase in the dispensing of psychoactive drugs following the terrorist attacks of 11 September 2001, and this effect varied by geographic proximity to the events. These findings build on the growing body of knowledge on the pervasive effects of disasters and terrorist events for population health, and demonstrate the need to include mental and behavioral health as key components of surge capacity and public health response to mass traumas.

STUDY OBJECTIVE: We assess emergency department (ED) utilization by a population whose health care encounters can be tracked and quantified for behavioral and mental health conditions in the aftermath of the terrorist attacks of September 11, 2001. METHODS: We assessed presentations to EDs by using Medicaid analytic extract files for adult New York State residents for 2000 and 2001. We created 4 mutually exclusive geographic areas that were progressively more distant from the World Trade Center and divided data into 4 periods. All persons in the files were categorized by their zip code of residence. We coded primary ED diagnoses for posttraumatic stress disorder, substance abuse, psychogenic illness, severe psychiatric illness, depression, sleep disorders, eating disorders, stress-related disorders, and adjustment disorders. RESULTS: There was a 10.1% relative temporal increase in the rate of ED behavioral and mental health diagnoses after the September 11, 2001, terrorist attacks for adult Medicaid enrollees residing within a 3-mile radius of the World Trade Center site. Other geographic areas experienced relative declines. In population-based comparisons, Medicaid recipients who lived within 3 miles of the World Trade Center after the September 11, 2001, terrorist attacks had a 20% increased risk of an ED mental health diagnosis (prevalence density ratio 1.2; 95% confidence interval 1.1 to 1.3) compared to those who were non-New York City residents. CONCLUSION: The complex role that EDs may play in responding to terrorism and disasters is becoming increasingly apparent. To the best of our knowledge, this is the first report of a quantifiable increase in ED utilization for mental health services by persons exposed to a terrorist attack in the United States.

BACKGROUND: Numerous studies have suggested that emergency medical services (EMS) providers are ill-prepared in the areas of training and equipment for response to events due to weapons of mass destruction (WMD) and other public health emergencies (epidemics, etc.). METHODS: A nationally representative sample of basic and paramedic EMS providers in the United States was surveyed to assess whether they had received training in WMD and/or public health emergencies as part of their initial provider training and as continuing medical education within the past 24 months. Providers also were surveyed as to whether their primary EMS agency had the necessary specialty equipment to respond to these specific events. RESULTS: More than half of EMS providers had some training in WMD response. Hands-on training was associated with EMS provider comfort in responding to chemical, biological, and/or radiological events and public health emergencies (odds ratio (OR) = 3.2, 95% confidence interval (CI) 3.1, 3.3). Only 18.1% of providers surveyed indicated that their agencies had the necessary equipment to respond to a WMD event. Emergency medical service providers who only received WMD training reported higher comfort levels than those who had equipment, but no training. CONCLUSIONS: Lack of training and education as well as the lack of necessary equipment to respond to WMD events is associated with decreased comfort among emergency medical services providers in responding to chemical, biological, and/or radiological incidents. Better training and access to appropriate equipment may increase provider comfort in responding to these types of incidents.

BACKGROUND: Both children and older adults are thought to sustain burns serious enough to warrant hospitalization disproportionately more often than other age groups, but the incidence, injury characteristics, and outcome have not been precisely defined. METHODS: Patients hospitalized with a burn diagnosis were identified from hospital discharge data from California, Florida, New Jersey, and New York for the 5-year period 2000-2004. RESULTS: In those states, 60,024 residents were hospitalized with a diagnosis of burn and/or inhalation injury according to the International Classification of Diseases, 9th Revision, Clinical Modification diagnosis codes. Using population data from the United States Census 2000, we found that the average annual incidence of hospitalization with a burn diagnosis in these 4 states was 155 per million (per M) (95% confidence interval,153-158). There were 13,453 children under 15 years of age: incidence, 163 per M (range, 157-169). Of these 9508 (70%) were under 5 years of age: incidence, 363 per M (range, 347-379). In contrast, there were 10,686 patients 65 years of age or older: incidence, 214 per M (range, 205-224), of whom 2091 were at least 85 years old: incidence, 347 per M (range, 314-380). The incidence of hospitalization with a burn diagnosis for patients 15 to 64 years of age was 141 per M (range, 138-145). Compared with children younger than 15 years, patients aged 65 years and older more often had flame burns (odds ratio [OR], 2.12), burns of 20% or more of body surface area (OR, 2.41), inhalation injury (OR, 2.88), respiratory failure (OR, 4.48), and death (OR, 16.53), all P < .0001. CONCLUSIONS: Older individuals are the most vulnerable to the morbidity and mortality of burn injury. Prevention strategies targeted to those older than 65 years should be developed.

The hypothesis that relative to cars, light trucks and vans (including sports utility vehicles) are more likely to result in fatal paediatric pedestrian injury was investigated. It was further hypothesized that this increased risk is a result of head injuries. The study sample consisted of 18 117 police records of motor vehicles involved in crashes in which one or more pedestrians aged 5 to 19 years old was injured or killed. Frequencies and case fatality ratios for each vehicle body type were calculated. A logistic regression analysis was conducted, with light truck or van vs. car as the exposure variable and fatal/non-fatal pedestrian injury as the outcome variable. After controlling for driver age, driver gender, vehicle weight, road surface condition and presence of head injury, 5 to 19 year-olds struck by light trucks or vans were more than twice as likely to die than those struck by cars (odds ratio (OR) 2.3; 95% CI 1.4, 3.9). For the 5 to 9 year-old age group, light trucks and vans were four times as likely to be associated with fatal injury (OR 4.2; 95% CI 1.9, 9.5). There was an association between head injury and light trucks and vans (OR 1.2; 95% CI 1.1, 1.3). It was concluded that vehicle body type characteristics play an important role in paediatric pedestrian injury severity and may offer engineering-based opportunities for injury control.

Effective postterrorism public health interventions require the recognition that behavioral consequences are, in fact, the intent of terrorists. The authors searched published and unpublished post-1980 studies that documented population-level behavioral and psychological consequences of terrorist incidents, focusing on posttraumatic stress disorder (PTSD). Results were tabulated, and random effects models were used to calculate overall effect sizes. The analysis indicates that in the year following terrorist incidents, the prevalence of PTSD in directly affected populations varies between 12% and 16%. The review also shows that this prevalence can be expected to decline 25% over the course of that year. These prevalence estimates mask great variability, depending on who is being studied, who is conducting the study, and where the event occurred. Higher rates of disease are reported for survivors and rescue workers, and higher overall rates are also reported from studies conducted in Western Europe compared with studies conducted in North America. Prior psychiatric diagnoses are strongly associated with subsequent PTSD and may be a useful triage factor, particularly when considered together with factors such as female gender and direct exposure to events as either a survivor or rescuer. The review indicates that these associations are consistent across study types and environments and represent important variables to consider when developing triage, outreach, and treatment programs.
