Risk factors for prescription drug overdose: A retrospective case-control study of emergency department patients
Principal Investigator: Bharath Chakravarthy, MD, MPH
This research project is a matched case-control study that examines the prescription history of controlled substances for adult patients treated at the UC Irvine Medical Center Emergency Department for intentional and unintentional drug overdoses. The purpose of this study is to identify whether OD patients are prescribed more controlled substances (number and type of drugs, dosage, etc.) than their control counterparts.

Post-traumatic stress disorder in trauma patients arriving to the emergency department; inter-rater reliability among physicians using a novel screening tool
Principal Investigator: Bharath Chakravarthy, MD, MPH
This research study assesses whether doctors treating trauma patients can predict when a patient will have long-term problems such as post-traumatic stress disorder as a result experiencing trauma. It also assesses whether a specific survey called “PsySTART” can be used to make these predictions. PsySTART, a mental health triage instrument, has been developed to facilitate the rapid identification of high-risk adults and children, particularly in mass-casualty events. The purpose of PsySTART is to rapidly triage high-risk individuals using relatively brief, objective, evidence-based risk factors that will enable linking individuals to timely, acute interventions.

Determining the level of risk of suicide or self-harm in patients presenting to ED with psychiatric complaints: A qualitative study
Principal Investigator: Bharath Chakravarthy, MD, MPH
This research study analyzes how psychiatrists determine risk, stratification and disposition in psychiatric patients in the emergency department by examining the key components of the history and physical exam that are important in determining the level of risk of suicide or self-harm. The purpose of the study is to find information that can help improve the ability of emergency physicians to manage behavioral emergencies.

Analysis of pediatric psychiatric visits at two emergency departments
Principal Investigator: Bharath Chakravarthy, MD, MPH
This study is a retrospective measure of the trend in length of stay in the emergency department (ED) among pediatric psychiatric patients presenting at UC Irvine Medical Center and Long Beach Memorial Medical Center. The purpose of this study is to identify whether length of stay in the ED has changed in the two-year period.

Comparative effectiveness of alcohol brief intervention providing by computer compared to trained person
Principal Investigator: Ying Hoonpongsimanont, MD, MS
Randomized trial for trauma and non-trauma patients presenting to the UC Irvine Medical Center Emergency Department to ascertain whether a trained alcohol interventionist is more effective in changing drinking habits versus the CASI computerized program intervention.

The effect of alcohol screening and brief intervention on alcohol consumption in emergency department patients who are adolescents
Principal Investigator: Shahram Lotfipour, MD, MPH
Randomized study comparing CASI to the standard of care for pediatric patients in the emergency department. The purpose of this research is to examine the effectiveness of Computerized Alcohol Screening and brief Intervention (CASI) in the UC Irvine Medical Center Emergency Department in adolescents. CASI is a web-based computerized program designed to help identify at-risk or dependent alcohol drinkers and provide resources to help improve their habits.

An association of alcohol outlet density, residential proximity and trauma victims testing positive for alcohol
Principal Investigator: Shahram Lotfipour, MD, MPH
This research is to identify the individual population and environmental characteristics that influence the risk of injury to trauma patients to aid in efforts to help reduce the overall risk and the costs associated with them. This study looks at all trauma patients testing positive for alcohol over the last two years at UC Irvine Medical Center to evaluate the distance and density of alcohol outlets from the trauma patient’s residence and EMS pickup location.

A needs-analysis of uninsured patients in the hospitalist program at UC Irvine Medical Center
Principal Investigator: Shahram Lotfipour, MD, MPH
This study was created to understand the healthcare needs of uninsured UC Irvine Health Hospitalist Program patients at UC Irvine Medical Center, to determine the factors that contributed to their presentation at the hospital.

Comparative analysis of lost to follow-up emergency department patients who completed alcohol screening
Principal Investigator: Shahram Lotfipour, MD, MPH
The purpose of this research is to compare demographic factors, alcohol drinking patterns, emergency department diagnosis and readiness to change scores in emergency department patients who previously underwent alcohol screening. This entails comparing how patterns of alcohol drinking and readiness to change contribute to follow-up attrition.

A retrospective study on the association between AUDIT domain scores and demographic factors, and readiness-to-change scores in emergency and trauma patients
Principal Investigator: Shahram Lotfipour, MD, MPH
This research is to assess alcohol drinking patterns in emergency department patients and trauma patients who have previously undergone alcohol screening using Alcohol Use Disorder Identification Test (AUDIT). Individual performance in each of three test domains examines how the participants' characteristics such as age, gender, ethnicity and education level might influence performance in each domain and how they contribute to the overall AUDIT score.

Longitudinal observational follow up of computer-aided diabetes risk assessment and education (CADRAE) in a medically underserved population in Amman, Jordan
Principal Investigator: Shahram Lotfipour, MD, MPH
This research study examines the effectiveness of computer-aided diabetes risk assessment and education (CADRAE) among adults in Amman, Jordan. Effective integration of technology. such as portable tablet computers and computerized screening programs, into public health education efforts has a high potential impact on populations with limited access to primary healthcare providers.

Education

Increasing off-service resident productivity while on their emergency department rotation using the Hawthorne effect
Principal Investigator: Bharath Chakravarthy, MD, MPH
This study will determine whether requiring rotating residents to complete a shift card for each shift increases their productivity while rotating in the emergency department. Motivating off-service residents rotating in the ED through shift cards can potentially be a simple and cost-effective method to improve system-based practices and utilization of resources.
