Outcomes and Health Services Research

Outcomes and Health Services Research (HSR) is conducted in every division in the Department of Surgery, focusing on advancing the knowledge, understanding and implementation of best-evidence care in surgery. Research projects are diverse and include cross-disciplinary work in health disparities, quality improvement, surgical outcomes, disease management and population health. Researchers have significant experience with big data, institutional data linkage and both quantitative and qualitative research methods. Our researchers also have a long history of collaborations with HSR researchers across other departments and institutions beyond UAB.

In tandem with these research efforts, the department is passionate about training the next generation of surgeon-scientists and researchers. Our department has deep experience working with students (high school, undergraduate, graduate, and medical/graduate school), residents and faculty. In addition, weekly conferences are held to discuss works-in-progress, conduct grant/manuscript reviews and to share ideas.

Our department's HSR portfolio is shown below. Please contact us if you would like to participate in these projects or if you have any questions.

  • Trauma & Injury Science

    The Center for Injury Science, founded in 1999, conducts research to promote injury prevention and to improve trauma care. Our mission is to improve outcomes from injury at all stages of care, from the prehospital setting through to resuscitation, acute care and rehabilitation. Our approach is cross-cutting and multidisciplinary. Clinicians from many specialties – including trauma surgeons, emergency medicine physicians, anesthesiologists, intensivists and rehabilitation specialists – work closely with epidemiologists, basic scientists, biostatisticians, health economists, health psychologists and methodologists. The center is comprised of four units: the Clinical Trials Unit, the Trauma Care Delivery Research Unit, the Basic Science and Translational Research Unit, and the Evidence Synthesis Unit.

    Faculty conducting research in this space include: 

  • Vascular Surgery

    Outcomes research in vascular surgery focuses on analyzing and improving outcomes for patients with complex vascular disease. Reducing readmissions, defining predictors of poor outcomes, and reducing health disparities are a primary focus. In addition to research focusing on evaluating our local care practices through review of electronic medical records, current research projects use large databases including the Society for Vascular Surgery Vascular Quality Initiative (VQI), Vascular Implant Surveillance and Interventional Outcomes Network (VISION) Coordinated Registry Network and International Consortium of Vascular Registries (ICVR) databases.

Quality Improvement

  • Enhanced Recovery Program
    Enhanced Recovery Programs (ERPs) link multimodal perioperative processes (e.g., patient education, early mobilization, non-opioid pain regimes, etc.) into a fully integrated package to reduce LOS, POCs and readmissions for patients after major surgery. ERP is also a model through which we may better understand mechanisms of disparities at the patient, provider and healthcare system levels. UAB ERPs currently span nine surgical service lines with further projected growth. Over 4,000 UAB patients have undergone ERP and we have one of the nation's largest databases for outcomes research.

  • Surgical Communication and Behavior
    Perioperative communication between surgeons and family members is a critical time, especially the time immediately following the procedure. The experience is susceptible to communication breakdowns, and uncertainty heightens emotions and anxiety for the patient’s family, creating barriers to communicating critical information. While previous studies have focused on decreasing anxiety during wait times, no interventions focus on optimizing the communication following surgery. This postoperative conversation is critical to building trust between caregivers and surgeons, addressing caregiver needs, and equipping caregivers with knowledge needed to provide post-surgical care at home. Improving this process could impact the patient’s susceptibility to infections or other complications, length of hospital stay, and potential unplanned hospital readmissions.
  • VA Readmissions
    Hospital readmissions have recently been targeted as a hospital quality measure. Readmissions can increase both costs and resource utilization and are associated with poorer patient outcomes. While much research on readmissions has been done in the medical patient population, there has been little study of reasons for readmission in the surgical patient population. In contrast to medical admissions, index surgical admissions are usually planned, and post-hospital care coordination often begins before the patient is admitted to the hospital. It will be important to identify which patients have high risk for readmission after surgery and to understand whether a readmission is potentially preventable, represents a quality of care issue or indicates failure of the care transition plan. By incorporating the contributions of patient comorbidity, self-efficacy, caregiver status, procedure complexity and system factors on readmissions, we can develop a risk prediction tool to identify those patients at highest risk.
  • Virtual Acute Care for Elders
    More than 150,000 Americans 65 years and older will have major gastrointestinal surgery annually, and these patients frequently experience functional and cognitive decline, leading to reduced quality of life and diminished survival. Clinical outcomes in older patients are significantly improved when hospitals utilize an Acute Care for Elders (ACE) treatment model in which older patients are placed in specialized units where a multidisciplinary team follows evidence-based geriatric care practices. Due to a shortage of geriatric-trained physicians, dissemination of the ACE model for surgical patients has been limited, and most hospitals lack the financial resources to create dedicated ACE units. Geriatricians and surgeons at UAB have implemented a modified version of the ACE model (Virtual ACE) to address these problems with dissemination of the ACE model. Virtual ACE is a novel combination of information technology and engagement with nursing staff to deliver ACE quality care without requiring specialized geriatric units.

Health Disparities

  • Cancer Disparities

    Cancer-related disparities may be related to differences in cancer incidence, prevalence, screening rates, stage at diagnosis, treatments received, as well as cancer-related morbidity, mortality and survivorship. Over the past several decades, progress in cancer prevention, early detection and treatment has led to overall decrease in cancer death rates. However, all populations have not benefited equally from these advances. These disparities based on race, ethnicity, socioeconomic status, geography, are due to multi-level underlying causes. The multiple underlying factors contributing to disparities have not yet been understood, which is a gap in our understanding of surgical disparities and our ability to reduce them. It is important to identify, understand, and develop interventions to reduce these disparities. We use both quantitative (national databases, clinical registries, etc.) and qualitative (interviews, focus groups, etc.) methods to help address these questions.

    Faculty conducting research in this space include:

  • Colorectal and Other Gastrointestinal Disease Disparities

    Research in this area focuses on improving the outcomes after bariatric surgery, surgery for inflammatory bowel disease, as well as other minimally invasive and abdominal wall operations. Our faculty study methods to improve post-operative outcomes including decreasing morbidity and length of stay.


    Enhanced Recovery Programs (ERPs) link multimodal perioperative processes including patient education, early mobilization, and non-opioid pain regimes into a fully integrated package to reduce hospital length of stay, postoperative complications and readmissions for patients after major surgery. UAB ERPs currently span nine surgical service lines, and over 4,000 UAB patients have undergone ERP after surgery, resulting in a large database with which to study various quality improvement and other outcomes.


    Faculty conducting research in this space include:

  • Surgical Disparities and Health Literacy

    Health disparities in surgery (i.e., surgical disparities) exist. Many surgical populations suffer from disproportionately worse access, care and outcomes in surgery. Racial/ethnic disparities, which represent one type of disparity, have been demonstrated across many surgical disciplines including colorectal surgery. The factors that would reduce these inequities are unknown, which exposes a major gap in our understanding of surgical disparities and our ability to reduce them. Our faculty use both quantitative (national databases, clinical registries etc.) and qualitative (interviews, focus groups etc.) methods to help address these questions.

    We also apply important concepts, such as health literacy, to better frame our approaches. Low health literacy is associated with poor health outcomes in many chronic diseases and may have an important role in determining surgical outcomes. Studies have observed that patient education, understanding, and engagement in surgical processes lead to better surgical outcomes and reduced disparities.

    These observations suggest a potential role for health literacy, defined as an individual’s capacity to obtain, process and understand health information, in determining surgical outcomes. Our faculty are focused on developing, and implementing, health-literacy based interventions in surgery.

    Faculty conducting research in this space include:

  • Transplant Disparities

    The Transplant Epidemiology & Analytics in Medicine (T.E.A.M.), an interdisciplinary health services research group within the UAB Comprehensive Transplant Institute, supports a broad range of health services research projects aimed at improving outcomes for liver and kidney transplant recipients and living donors and overcoming health disparities in access to and outcomes of transplantation.

    Areas of focus for this program include:

    • Liver transplant candidate evaluation, management, and outcomes for adults, ensuring that culturally and ethnically appropriate assessment strategies are used to eliminate age and racial health disparities.
    • Development of novel risk prediction tools to accurately identify pre-donation risk factors associated with the development of post-donation comorbidities.
    • Examination of regional variation in organ use, allocation, listing practices, and sex-based disparities through national registry data.
    • Cost-effectiveness analysis to optimize strategies for organ allocation and treatment. Quantitative investigation is complemented by a wide range of qualitative and mixed methods to improve our understanding of the needs of our patients and donors.

    Current randomized clinical trials include educational strategies to assist patients in identifying living donors and integration of HIV-positive kidneys and livers into transplantation.
