Post-traumatic stress disorder in an emergency department population one year after Hurricane Katrina.

BACKGROUND: Hurricane Katrina resulted in a significant amount of injury, death, and destruction. STUDY OBJECTIVES: To determine the prevalence of, and risk factors for, symptoms of post-traumatic stress disorder (PTSD) in an emergency department (ED) population, 1 year after hurricane Katrina. METHODS: Survey data including the Primary Care PTSD (PC-PTSD) screening instrument, demographic data, and questions regarding health care needs and personal loss were collected and analyzed. RESULTS: Seven hundred forty-seven subjects completed the survey. The PC-PTSD screen was positive in 38%. In the single variate analysis, there was a correlation with a positive PC-PTSD screen and the following: staying in New Orleans during the storm (odds ratio [OR] 1.73, 95% confidence interval [CI] 1.28-2.34), having material losses (OR 1.64, 95% CI 1.03-2.60), experiencing the death of a loved one (OR 1.96, 95% CI 1.35-1.87), needing health care during the storm (OR 2.01, 95% CI 1.48-2.73), and not having health care needs met during the storm (OR 2.00, 95% CI 1.26-3.18) or after returning to New Orleans (OR 2.29, 95% CI 1.40-3.73). In the multivariate analysis, the death of a loved one (OR 1.87, 95% CI 1.26-2.78), being in New Orleans during the storm (OR 1.69, 95% CI 1.22-2.33), and seeking health care during the storm (OR 1.69, 95% CI 1.22-2.35) were associated with positive PC-PTSD screens. CONCLUSIONS: There was a high prevalence of PTSD in this ED population surveyed 1 year after hurricane Katrina. By targeting high-risk patients, disaster relief teams may be able to reduce the impact of PTSD in similar populations.

Sexual assault victims in the emergency department: analysis by demographic and event characteristics.

The objective of this study was to analyze demographic and event characteristics of patients presenting to the Emergency Department (ED) for evaluation after sexual assault, using a Sexual Assault Nurse Examiner standardized database. Data were prospectively collected as part of the Sexual Assault Nurse Examiner program at an urban teaching hospital. This study reviewed all ED patient records with a complaint of sexual assault between January 1, 2000 and December 31, 2004. Data were collected on 1172 patients; 92.6% were women, with a mean age of 27 years. The sample was 59.1% black, 38.6% white, and 2.3% "Other." Black victims of sexual assault were significantly more likely to be young (25 years or less) than Whites. Over half (54%) reported involvement of drugs or alcohol during the event. Fifty-three percent knew their assailant(s), and black and young patients were significantly more likely to know the perpetrator(s). Threats of force were common (72.4% of sample), and multiple assailants were uncommon (18.1% of sample). Physical evidence of trauma was present in more than half (51.7%), with increased rates among Whites and older persons. Multivariate analysis showed that race, age, threats, and substance use during the event were independent risk factors for evident trauma on physical examination. Survivors of sexual assault who present to the ED are overwhelmingly female, relatively young, often know the perpetrator of the event, and are likely to be threatened and show signs of physical trauma. Differences between patients according to demographic and event characteristics may have important implications for ED management and treatment plans.

Male victims of partner violence: prevalence and accuracy of screening tools.

The objective of this study was to determine the accuracy of two brief surveys for detection of male victims of intimate partner violence (IPV) in the Emergency Department (ED). This study was conducted prospectively in an urban, teaching hospital over 6 weeks; all men triaged to the acute care portion of the ED were eligible for enrollment. Exclusion criteria included age less than 18 years, refusal, altered mental status, or condition requiring lifesaving intervention. Data included demographics, Revised Conflict Tactics Scale (CTS2) score, and scores on two brief surveys of IPV: the HITS ("Hurt/Insult/Threaten/Scream") scale and the Partner Violence Screen (PVS). The CTS2 uses previously validated population scores for female to male psychological aggression and physical assault. Neither the HITS nor the PVS has been validated for use in the ED for detecting male victims of IPV. There were 116 men approached for enrollment; nearly half completed all surveys. Mean age was 41.8 years, and the sample was 73% African-American and 20% white. Thirty-nine percent had positive scores on the psychological aggression portion of the CTS2, whereas 20% had positive scores on the physical assault subscale. Comparing the HITS and PVS to both the psychological and physical portions of the CTS2 resulted in sensitivities of 30-45% and specificities of 83-88%. False negative rates on the two brief surveys ranged from 14-33%, and negative predictive values and positive likelihood ratios were low. Neither the HITS nor the PVS accurately screens male victims of IPV in the ED. Further research is needed to develop a valid, brief screening test to identify male victims of IPV in an acute setting.

Symptoms of post-traumatic stress disorder among emergency medicine residents.

There have been anecdotal reports of post-traumatic stress disorder (PTSD) in physicians responding to mass casualty events. No formal, prospective study has addressed the presence of PTSD symptoms as a result of the work of Emergency Medicine residents in non-mass casualty settings. The purpose of this study is to evaluate the presence of symptoms of PTSD among Emergency Medicine residents (EMR). The study was a survey of EMR, administered in an anonymous, voluntary format in late June 2001. The survey was conducted at an Emergency Medicine residency program that serves a large, urban, county hospital. Four groups, incoming interns and three EM resident classes were surveyed. PTSD symptoms were divided into three categories according to the DSM IV. The Jonckheere-Terpstra test for trends was applied to each of the three categories of symptoms. Sixty-three surveys were administered, with a 93.6% response rate. All respondents reported experience with patient death or dying. Seven residents reported sufficient symptoms to meet the DSM IV criteria for PTSD. Each of the three symptom categories showed a statistically significant increase in the proportion of positive responses as the resident time in training increased (p < 0.01). In conclusion, many EM residents reported symptoms of PTSD. Symptoms of PTSD significantly increased as resident level of training increased.

The epidemiology of skydiving injuries: World freefall convention, 2000-2001.

The purpose of this study is to describe the prevalence and types of injuries incurred by civilian skydivers using contemporary equipment under conventional conditions. Injury data were collected at the World Freefall skydiving convention (WFFC), during two consecutive periods of operation, August 4-13, 2000 and August 3-12, 2001. During the study periods, 8976 skydivers made 117,000 skydives. The First Aid Station at the WFFC treated 204 patients for injuries related to skydiving, at a rate of 17.4/10,000 (injuries/skydives). Most injuries were minor (66%) and required only simple first aid. Significant injuries, defined as those requiring treatment in the emergency department, occurred at a rate of 6.0/10,000 (injuries/skydives). The rate of hospitalization was 1.8/10,000 skydives. There was one fatality during this study. We believe these results provide a current update regarding the risk and types of injury related to recreational skydiving.

The prevalence of female-to-male intimate partner violence in an urban emergency department.

Female-to-male intimate partner violence (IPV) recently has become a recognized health care issue. We screened a heterosexual male Emergency Department population for IPV using the HITS scale, a four-question survey. Two hundred eighty-two men were enrolled in the study. Basic demographics, along with the answers to the HITS scale, were analyzed. Of the men screened, 29.3% had a positive history of IPV. Men who were positive for IPV were more likely to score higher on questions regarding the frequency of verbal aggression than actual or threatened physical violence. This study reinforces the need to screen both genders for IPV in the Emergency Department.

Ultrasound guidance versus the landmark technique for the placement of central venous catheters in the emergency department.

OBJECTIVE: To compare ultrasound (US)-guided vs. landmark-guided techniques for central venous access (CVA) in the emergency department. METHODS: This was a prospective study of consecutive patients enrolled at a university teaching hospital with an annual census of approximately 100,000. On even days patients had CVA with ultrasonic assistance; patients presenting on odd days had CVA via traditional landmark techniques. Ultrasound users were emergency medicine faculty or residents who completed a one-hour training session. A data collection tool with 17 variables was completed for each central line placed. Variables were compared using the independent t-test, Fisher's exact test, and the non-parametric Mann-Whitney U test. RESULTS: Between August 1, 2000, and February 1, 2001, data for 122 subjects (n = 51 for US, and n = 71 for landmark) were collected. Variables with statistically significant differences are as follows. Mean (+/-SD) time from skin puncture to blood flash was 115 (+/-184) seconds for the US group vs. 512 (+/-698) seconds for the landmark group (p < 0.0001). The mean number of CVA attempts in the US group was 1.6 (+/-1.0) vs. 3.5 (+/-2.7) in the landmark group (p < 0.0001). Acute complications were comparable between groups. Comparisons for time, number of CVA attempts, and complications were done specifically for a subset of patients considered to be "difficult stick" due to predefined criteria regarding body habitus or vascular disease. Patients considered to be "difficult sticks" required a significantly longer amount of time (p < 0.001) for CVA via the landmark technique than patients considered to be "difficult sticks" who had CVA with ultrasonic guidance. Time to line placement for the landmark group was 462.7 (+/-627) seconds vs. 93.3 (+/-176) seconds in the US group. Comparing the same subset also revealed an increase in number of required CVA attempts for the landmark technique group. The number of acute complications in the "difficult stick" patients did not show statistical significance (p = 1.00). The landmark group had 60% "difficult sticks," while the ultrasound group had 80%, although the difference was not statistically significant (p = 0.08). CONCLUSIONS: Emergency physicians with limited training and experience are able to use ultrasound as an adjunct for central venous access. Ultrasound technology may decrease the number of CVA attempts required to cannulate a central vein and will decrease the amount of time required to cannulate the vein starting from the time when the needle is on the skin, after the ultrasound machine has been set up and turned on. These results are especially true for those patients considered to be "difficult sticks."
