Research Projects

Below is a list highlighting the projects and accomplishments of our ESHM CRP investigators and other ESHM faculty:

Research Projects involving Hospital Medicine Clinical Research Program Investigators

Prognostic utility of biomarkers of collagen turnover, matrix metalloproteinases (MMP 2, 3, and 9) and tissue-inhibitors of metalloproteinases (TIMP-1, TIMP-2) over contemporary prediction models, and their correlation with cardiac function and exercise capacity in patients with low ejection fraction heart failure
Researcher: Vikas Bhalla MD
Hypothesis: Biomarkers of collagen turnover will correlate strongly with both cardiac structure & function and functional capacity in low ejection fraction heart failure patients.

Characteristics of peripherally inserted central catheters (PICCs): an analysis of patient characteristics, patterns of use, prevalence, necessity, complications, and alternatives in the hospital setting 
Researchers: Brian C. Erb MD FASN, David Tong MD MPH
Hypothesis: We hypothesize that the prevalence and duration of PICCs are unnecessarily high and that opportunities can be identified to reduce patient exposure to the hazards associated with PICCs, in particular for patients with chronic kidney disease.

Goal-directed teamwork to improve frontline patient care
Researchers: Julie Hollberg MD, Jason Stein MD
Hypothesis: Highly functional frontline teams can be created through particular staffing models, rounding formats, use of daily goals checklists, and attention to dimensions of teamwork, such as cohesiveness, communication, role clarity, and goal clarity.

Prevalence, risk factors, and impact on clinical outcome of multi-drug resistant organisms: Carbapenem-resistant Klebsiella pneumoniae
Researchers: Ketino Kobaidze MD PhD
Hypothesis: A better understanding of transmission of Carbapenem-resistant Klebsiella pneumoniae will improve the effectiveness of the infection control program across Emory hospitals.

Prevalence of abnormal values and effect of alerts at the time of discharge
Researcher: George Mathew MD
Hypothesis: Dynamically generated electronic alerts at time of discharge by CPOE (computerized physician order entry), triggered by specific abnormal vital sign or laboratory values, will help identify and alter management decisions for patients in a large tertiary care hospital.

DiaSys: Computerized decision support to improve diabetes management in primary care
Researcher: Arun Mohan MD MBA
Hypothesis: Decision support technology will provide primary care providers with individualized treatment recommendations, and the underlying rationale; decision support recommendations for changes in therapy witll be considered valid by endorinologists; use of glucose monitoring-based computerized decision support by PCPs and their nursing staff will be feasible, safe, and effective.

Improving glycemic control in hospitalized ICU and non-ICU patients
Researcher: Hasan Shabbir MD
Hypothesis: To capture the potential strengths of team-based care and specialist oversight, we hypothesize that a glycemic control order set combined with real-time nursing interventions can improve best-practice utilization for glycemic control among hospitalized patients.

Improving glycemic control in hospitalized patients through a novel insulin drip conversion equation to standardize transition to subcutaneous insulin 
Researcher: Randy Smith MD
Hypothesis: We hypothesize that for patients on insulin infusions, if an equation that takes into account caloric intake and intravenous insulin needs is used to determine subcutaneous insulin dosage, glycemic control will be achieved more predictably and rapidly than if a physician uses other means to determine subcutaneous insulin dosage.

Increasing prevalence of venous thromboembolism (VTE) prophylaxis in the hospital through measure-vention
Researcher: Jason Stein MD
Hypothesis: Real-time measurement to identify patients without VTE prophylaxis can serve as both an intervention and a measurement system to increase and track prevalence of VTE prophylaxis.

Reducing central line associated blood stream infections (CLABSIs) and eliminating the idle central venous catheter through measure-vention
Researcher: Sheri Chernetsky Tejedor MD
Hypothesis: Real-time measurement to identify patients with central lines can serve as both an intervention and a measurement system to prompt removal of idle central lines.

Improving transfusion utilization among inpatient physicians
Researcher: Dan VanderEnde MD DTM&H
Hypothesis: An educational program with audit-and-feedback can improve transfusion practices in the hospital.  

Prospective evaluation of hospitalist and intensivist staffing models in the intensive care unit
Researcher: Kristin Wise MD
Hypothesis: Hospitalists can provide equivalent mortality outcomes for critically ill patients.
