The transition from acute to persistent pain: the identification of distinct trajectories among women presenting to an emergency department.

Posttraumatic stress disorder (PTSD) symptoms and other negative psychosocial factors have been implicated in the transition from acute to persistent pain. Women (N = 375) who presented to an inner-city emergency department (ED) with complaints of acute pain were followed up for 3 months. They completed a comprehensive battery of questionnaires at an initial visit and provided ratings of pain intensity at the site of pain presented in the ED during 3 monthly phone calls. Latent class growth analyses were used to detect possible trajectories of change in pain intensity from the initial visit to 3 months later. A 3-trajectory solution was found, which identified 3 groups of participants. One group (early recovery; n = 93) had recovered to virtually no pain by the initial visit, whereas a second group (delayed recovery; n = 120) recovered to no pain only after 1 month. A third group (no recovery; n = 162) still reported elevated pain at 3 months after the ED visit. The no recovery group reported significantly greater PTSD symptoms, anger, sleep disturbance, and lower social support at the initial visit than both the early recovery and delayed recovery groups. Results suggest that women with high levels of PTSD symptoms, anger, sleep disturbance, and low social support who experience an acute pain episode serious enough to prompt an ED visit may maintain elevated pain at this pain site for at least 3 months. Such an array of factors may place women at an increased risk of developing persistent pain following acute pain.

Social support, social undermining, and acute clinical pain in women: Mediational pathways of negative cognitive appraisal and emotion.

Women may be disproportionately vulnerable to acute pain, potentially due to their social landscape. We examined whether positive and negative social processes (social support and social undermining) are associated with acute pain and if the processes are linked to pain via negative cognitive appraisal and emotion (pain catastrophizing, hyperarousal, anger). Psychosocial variables were assessed in inner-city women (N = 375) presenting to an Emergency Department with acute pain. The latent cognitive-emotion variable fully mediated social undermining and support effects on pain, with undermining showing greater impact. Pain may be alleviated by limiting negative social interactions, mitigating risks of alternative pharmacological interventions.

Race-related differences in acute pain complaints among inner-city women: the role of socioeconomic status.

Previous research has shown that African Americans (AA) report higher pain intensity and pain interference than other racial/ethnic groups as well as greater levels of other risk factors related to worse pain outcomes, including PTSD symptoms, pain catastrophizing, and sleep disturbance. Within a Conservation of Resources theory framework, we tested the hypothesis that socioeconomic status (SES) factors (i.e., income, education, employment, perception of income meeting basic needs) largely account for these racial/ethnic differences. Participants were 435 women [AA, 59.1%; Hispanic/Latina (HL), 25.3%; Non-Hispanic/White (NHW), 15.6%] who presented to an Emergency Department (ED) with an acute pain-related complaint. Data were extracted from psychosocial questionnaires completed at the participants' baseline interview. Structural equation modeling was used to examine whether racial/ethnic differences in pain intensity and pain interference were mediated by PTSD symptoms, pain catastrophizing, sleep quality, and sleep duration, and whether these mediation pathways were, in turn, accounted for by SES factors. Results indicated that SES factors accounted for the mediation relationships linking AA race to pain intensity via PTSD symptoms and the mediation relationships linking AA race to pain interference via PTSD symptoms, pain catastrophizing, and sleep quality. Results suggested that observed racial/ethnic differences in AA women's pain intensity, pain interference, and common risk factors for elevated pain may be largely due to racial/ethnic differences in SES. These findings highlight the role of social inequality in persistent health disparities facing inner-city, AA women.

Race, psychosocial vulnerability and social support differences in inner-city women's symptoms of posttraumatic stress disorder.

BACKGROUND/OBJECTIVES: Inner-city Black women may be more susceptible to posttraumatic stress disorder (PTSD) than White women, although mechanisms underlying this association are unclear. Living in urban neighborhoods distinguished by higher chronic stress may contribute to racial differences in women's cognitive, affective, and social vulnerabilities, leading to greater trauma-related distress including PTSD. Yet social support could buffer the negative effects of psychosocial vulnerabilities on women's health. METHODS/DESIGN: Mediation and moderated mediation models were tested with 371 inner-city women, including psychosocial vulnerability (i.e., catastrophizing, anger, social undermining) mediating the pathway between race and PTSD, and social support moderating psychosocial vulnerability and PTSD. RESULTS: Despite comparable rates of trauma, Black women reported higher vulnerability and PTSD symptoms, and lower support compared to White Hispanic and non-Hispanic women. Psychosocial vulnerability mediated the pathway between race and PTSD, and social support moderated vulnerability, reducing negative effects on PTSD. When examining associations by race, the moderation effect remained significant for Black women only. CONCLUSIONS: Altogether these psychosocial vulnerabilities represent one potential mechanism explaining Black women's greater risk of PTSD, although cumulative psychosocial vulnerability may be buffered by social support. Despite higher support, inner-city White women's psychosocial vulnerability may actually outweigh support's benefits for reducing trauma-related distress.

PTSD Symptoms and Acute Pain in the Emergency Department: The Roles of Vulnerability and Resilience Factors Among Low-income, Inner-city Women.

BACKGROUND: Given high levels of traumatic stress for low-income, inner-city women, investigating the link between posttraumatic stress disorder (PTSD) and pain is especially important. PURPOSE: Using the conservation of resources theory, we investigated direct and indirect relationships of PTSD symptoms, vulnerability factors (ie, resource loss, depressive symptoms, and social undermining), and resilience factors (ie, optimism, engagement, and social support) to acute pain reports in a sample of low-income, inner-city women. METHODS: Participants (N=341; mean age=28 y; 58.0% African American) were recruited from an inner-city Emergency Department following presentation with acute pain. Study data were gathered from psychosocial questionnaires completed at a baseline interview. RESULTS: Structural equation modeling examined direct and indirect relationships among PTSD symptoms, vulnerability factors, and resilience factors on self-reported pain intensity and pain interference. PTSD symptoms were directly related to higher pain intensity and pain interference and indirectly related through positive associations with vulnerability factors (all Ps<0.05). Pathways through resilience factors were not supported. CONCLUSIONS: Results suggest that presence of PTSD symptoms is associated with elevated acute pain responses both indirectly via psychosocial vulnerability factors and directly, independent of the psychosocial factors assessed. Resilience factors did not play a significant role in determining acute pain responses. Consistent with conservation of resources theory, the negative effects of vulnerability factors outweighed the positive effects of resilience factors.

Medicaid beneficiaries who continue to use the ED: a focus on the Illinois Medical Home Network.

OBJECTIVES: Frequent, nonurgent emergency department use continues to plague the American health care system through ineffective disease management and unnecessary costs. In 2012, the Illinois Medical Home Network (MHN) was implemented to, in part, reduce an overreliance on already stressed emergency departments through better care coordination and access to primary care. The purpose of this study is to characterize MHN patients and compare them with non-MHN patients for a preliminary understanding of MHN patients who visit the emergency department. Variables of interest include (1) frequency of emergency department use during the previous 12 months, (2) demographic characteristics, (3) acuity, (4) disposition, and (5) comorbidities. METHODS: We performed a retrospective data analysis of all emergency department visits at a large, urban academic medical center in 2013. Binary logistic regression analyses and analysis of variance were used to analyze data. RESULTS: Medical Home Network patients visited the emergency department more often than did non-MHN patients. Medical Home Network patients were more likely to be African American, Hispanic/Latino, female, and minors when compared with non-MHN patients. Greater proportions of MHN patients visiting the emergency department had asthma diagnoses. Medical Home Network patients possessed higher acuity but were more likely to be discharged from the emergency department compared with non-MHN patients. CONCLUSIONS: This research may assist with developing and evaluating intervention strategies targeting the reduction of health disparities through decreased use of emergency department services in these traditionally underserved populations.

Successful collaborative model for STEMI care between a STEMI-referral and a STEMI receiving center.

BACKGROUND: Patients with ST-segment elevation myocardial infarction (STEMI) greatly benefit from a rapid door-to-balloon (D2B) time. For hospitals without a catheterization laboratory, it is imperative to establish partnerships with a STEMI receiving center (SRC). STEMI systems of care have been established to facilitate these relationships to improve rapid reperfusion. We describe the experience and benefits of such a relationship. METHODS: A partnership between our 2 institutions was established in April 2011. Saint Anthony Hospital (SAH) of Chicago is an inner city hospital with interventional cardiologists on staff, but no catheterization laboratory. Before the partnership, STEMI patients were transferred 8 miles to a percutaneous coronary intervention (PCI) hospital on the city's north side. Rush University Medical Center (RUMC) is an academic medical center with 24/7/365 PCI capability. SAH decided that a transfer relationship with a closer SRC would benefit patient care. The following steps were taken: both hospitals signed a STEMI transfer agreement for STEMI transfers regardless of insurance status; an education process occurred at both hospitals; agreement that transferred patients would follow-up at the STEMI referring hospital (SAH); a contract with a single ambulance provider was signed; a simple STEMI protocol was adopted. RESULTS: In 2010, SAH saw 20 patients with STEMI. Average time from patient arrival to leaving the emergency department (ED) [Door-in-Door-out (DIDO)] was 83 minutes, these times were not tracked carefully; approximate transfer time to SRC was 25 minutes; Door1-2-Balloon (D12B) time was not recorded. Since the new protocol, 44 patients transferred to RUMC for PCI to date. Median (inclusive minimum, maximum) time from ED arrival (D1) at referral hospital to SRC (D2) was 52 minutes (56, 192) for all PCI cases; 11 patients transferred did not have PCI; 1 patient expired upon arrival; and median time to first PCI device (D12B) was 86 minutes (53-167). DISCUSSION: Streamlining STEMI patient care to reduce D2B is a major priority. We have demonstrated that establishing a transfer program between a STEMI-Referral Hospital (SRH) and SRC can markedly improve time to reperfusion. This approach has resulted in D12B that match or exceeds the D2B for nontransfer patients at most STEMI-receiving hospitals.

The Rush University advanced trauma training program, a novel approach for military trauma training.

Nearly 90% of combat deaths occur on the battlefield before the casualty reaches a treatment facility. It has been shown that early intervention in trauma patients improves morbidity and mortality. Hence, the training of military health care providers in lifesaving measures is imperative to saving lives on the battlefield. To date, few courses exist to provide skills in combat-zone trauma stabilization and treatment. Even fewer offer training in the identification and treatment of post-traumatic stress disorders and traumatic brain injury. We set out to develop a multidisciplinary, comprehensive course to include didactic lectures as well as hands-on training and observational modules. Ten courses have been delivered to date. Thus far, feedback from military personnel and course participants has revealed the positive impact of the training program. In this manuscript, we present the layout of the program and its contents.

Achieving high quality in ST-segment elevation myocardial infarction care: one urban academic medical center experience.

Management of acute myocardial infarction with ST elevation (STEMI) remains a challenge for academic institutions. There are numerous factors at play from the time electrocardiogram is obtained to the time the patient arrives to a catheterization laboratory and the balloon is inflated. Academic hospitals that are located in large urban centers have to deal with staff living long distances from the facility, and therefore, assembling the catheterization team after-hours and on the weekends becomes a difficult task to achieve. There are other factors that contribute to time delays, such as, administering electrocardiograms in timely fashion, having emergency physicians activate the catheterization team, instead of contacting the cardiologist to discuss the case, and other time-sensitive factors. All of the aforementioned issues contribute to the delay. Yet, primary percutaneous coronary intervention is clearly demonstrated as the modality of choice in treatment of STEMI, which improves patient's morbidity and mortality. Therefore, it is imperative that institutions do all they can to improve their protocols and meet the core measures in the treatment of STEMI patients, including the door-to-balloon time of less than 90 minutes. Our institution started a quality improvement program for STEMI care in 1993 and has showed progressive improvement in use of aspirin, beta-blockers, angiotensin-converting enzyme inhibitors, and other medication, culminating in 95% to 100% use of these medications in 2003-2004, when we operated in accordance with the Get With The Guidelines program. Door-to-balloon time in less than 90 minutes became a new phase in our quality improvement process, and we achieved 100% compliance in the last 2 years.

A comprehensive disaster training program to improve emergency physicians' preparedness: a 1-year pilot study.

OBJECTIVES: The main objective of this pilot study was to measure the effectiveness of a 1-year comprehensive training program on the long-term cognitive competence in disaster preparedness among attending emergency physicians (EPs). DESIGN: Ten attending EPs participated in a year-long training program in disaster preparedness and management. A baseline pretraining test and self-evaluation questionnaire were administered to the participants. Post-training written test and self-evaluation questionnaire were repeated at 12 months after the completion of the program. SETTING: The study took place at an urban tertiary care medical center from July 2007 to June 2008. INTERVENTIONS: The training program was divided into three main categories: didactic core topics, formally recognized courses, and a practicum (drill). MAIN OUTCOME MEASURES: Pretraining and posttraining test scores in addition to pretraining and posttraining self-assessments were compared for disaster preparedness in various areas. RESULTS: There was a statistically significant increase in the overall post-test versus pretest scores on the written examination for the entire group (44.4 vs. 29.8, p < 0.005). In addition, statistically significant increases in each area of disaster preparedness were noted for the self-assessments (2.7 +/- 0.82 vs. 3.9 +/- 0.56, p = 0.01), where 1 means not prepared at all and 5 means extremely well prepared. CONCLUSIONS: Disaster preparedness is an essential area of clinical competence for EPs. Participation in a yearlong pilot training program demonstrated a statistically significant increase in cognitive competence among a pilot sample of EPs. More research is needed to validate the content of the training program and its instruments of evaluation.

Emergency Department greeters reduce door-to-ECG time.

INTRODUCTION: Screening for Acute Coronary Syndrome in chest pain patients can be initiated with a 12-lead electrocardiogram (ECG). Current American College of Cardiology/American Heart Association guidelines recommends getting an ECG performed and reviewed within 10 minutes of the time these patients present to the Emergency Department (ED). One innovative method to improve door-to-ECG time is by placing a trained greeter in the triage section of the ED. METHODS: This study was conducted over a 3-week period from September to October 2006, in a large urban academic medical center. The greeter was stationed in the triage area, and screened every patient entering the ED for the following symptoms/complaints: chest pain, shortness of breath, acute mental status changes in nursing home patients, dizziness, and nausea with or without vomiting in diabetic patients. The greeter obtained the ECG in the qualified patients, or alerted the triage. Data was collected on ECGs for all ED patients who presented with the above complaints in the absence of a greeter. RESULTS: In the 3 weeks of the study, data was collected on 126 cases. The greeter had obtained 40 ECGs, and 86 ECGs were done without the greeter. The average door-to-ECG times were significantly different between the groups. The study found 8.8 minutes in the greeter group versus 29.6 minutes in the nongreeter group (P = 0.000). CONCLUSION: ED triage greeter can be effectively used to obtain timely ECGs in suspected Acute Coronary Syndrome patients.

Who should be admitted to the chest pain observation unit?: one urban hospital experience.

INTRODUCTION: Patients at low risk for coronary artery disease (CAD) can be safely treated in the chest pain observation unit (CPOU). The goal of the study is to identify the differences in risk profiles of patients with positive and negative workup. METHODS: The study is a retrospective CPOU chart review conducted over 6 months. Data collected included gender, age, race, history of diabetes, hypertension, hyperlipidemia, family history of CAD, smoking, test results, and disposition. SPSS-12 program was used to analyze the differences in patient's characteristics. RESULTS: Two hundred forty-three patients were admitted to CPOU, 86% completed their workup, and 82% were discharged. Twenty-four (10%) patients had positive stress test, of whom 13 (54%) had > or =3 risk factors. CONCLUSION: It is practical to admit patients to the CPOU. The study has shown that "ideal" patients for CPOU are those with < or =2 risk factors for CAD.
