Implementation Science: Time and Motion Research to Improve Inpatient Diabetes Education at MedStar

Recently published research evaluated nurse and patient care technician workflow to identify opportunities for providing education to patients during care. The study sought to examine the feasibility of implementing a diabetes education program on a tablet computer in the hospital setting within existing nursing workflow with existing staff.

“Understanding Nursing Workflow for Inpatient Education Delivery: Time and Motion Study” was published in the Journal of Nursing Care Quality. The collaborative research team included Kelley M. Baker, MA and Kelly M. Smith, MSc, PhD from the MedStar Institute for Quality and Safety and MedStar Health Research Institute; and Michelle Magee, MD from the MedStar Diabetes Institute, MedStar Health Research Institute and the School of Medicine and Healthcare Sciences at Georgetown University.

The researchers conducted a time and motion study of nurses and patient care technicians on three medical-surgical units within a 912-bed tertiary care medical center. Two units were standard medical-surgical units and the third unit was a cardiac care unit. Five trained observers conducted observations in 2-hour blocks. During the observation block, one observer shadowed a nurse and one observer shadowed a patient care technician and recorded tasks, locations, and their durations using a web-based time and motion data collection tool.

The results of this observation study show that nurses spent approximately one-third of their time in direct patient care and 60% on the unit but not in a patient room. Patient care technicians spent 42% of their time in direct patient care, compared with nurses. Patient care technicians averaged 18.2 tasks per hour, while nurses averaged 16.2. On average, the amount of time spent for a direct patient care session was 3:42 minutes for nurses and 3:02 minutes for patient care technicians. For nurses, 56% of task durations were 2 minutes or less and 38% were 1 minute or less. For patient care technicians, 62% of task durations were 2 minutes or less and 44% were 1 minutes or less. Nurses visited 5.3 patient rooms per hour, while patient care technicians visited 9.4 patient rooms per hour.

The research team concluded that within the existing workflow of nurses and patient care technicians, constantly in and out of patient rooms, it is possible to deliver a tablet to the patient to provide diabetes education. However, the short duration of direct patient care sessions could potentially limit the ability of the nurses and patient care technicians to spend much time with each patient on instruction for use of the technology platform or in answering questions about the content. Diabetes self-management education and support is beneficial for persons living with diabetes. Future research should identify ways to implement technology to support education delivery in the hospital within the existing workflow for nurses and patient care technicians.

This research was funded by the National Institutes of Diabetes and Digestive and Kidney Diseases (R34DK109503). Dr. Smith also received funding from the National Center for Advancing Translational Sciences of the National Institutes of Health under Award Number UL1TR001409.

MedStar Investigator Receives the ‘Women Advancing Thyroid Research’ Award

Join us in congratulating Cristiane Gomes-Lima, MD, on her 2019 Women Advancing Thyroid Research (WATR) award from the American Thyroid Association (ATA). The WATR is a new award from the American Thyroid Association that recognizes and celebrates the work of women that are leading outstanding thyroid research. The WATR Award is sponsored by Mary Ann Liebert, Inc. through the Rosalind Franklin Society.

Dr. Gomes-Lima presented her award-winning work, “Do Molecular Profiles of Primary versus Metastatic Radioiodine Refractory Differentiated Thyroid Cancer Differ?” as a highlighted oral presentation at the ATA conference in late October. Her work was recognized at the Women in Thyroid meeting of the ATA.

The research focused on patients with advanced differentiated thyroid cancer. The research team sought to understand the molecular biology of the primary tumor and its metastases. They leveraged a bioinformatics approach to explore the interconnections of abnormal cancer genes in the context of thyroid physiology. In the era of precision medicine, this knowledge is essential to offer optimal treatment choices for our patients. “This award reassures my commitment to advance health through research,” said Dr. Gomes-Lima.

Dr. Cristiane Gomes-Lima graduated in Medicine from the University of Brasilia, Brazil. She completed her Internal Medicine residency, followed by Endocrinology fellowship and a master’s degree in Health Sciences. After working in clinical practice, she pursued a post-graduate research fellowship in thyroid cancer. She is currently a research fellow at MedStar Health Research Institute, in Washington, DC, and a guest researcher at the National Institutes of Health in Bethesda, Maryland.

In addition to Dr. Gomes-Lima, there were three other recipients of the award: Drs. Mariella Tutter, Silvia Ippolito, and Rosa Falcone. The ATA press release can be viewed here.

MedStar Researchers Evaluate Coffee and Tea Consumption in Relation to Risk of Rheumatoid Arthritis

Recently published collaborative research evaluated whether tea or coffee consumption is associated with an increased risk of incident rheumatoid arthritis using the Women’s Health Initiative Observational Study. The research team included members from MedStar Washington Hospital Center, National Institute of Nursing Research, Fred Hutchinson Cancer Research Center, National Institute of Environmental Health Science, MedStar Health Research Institute and Georgetown/Howard Universities Center for Clinical and Translational Sciences.

The Women’s Health Initiative was a long-term national health study which MedStar Health Research Institute joined as a collaborating center in 1994, under the direction of Barbara Howard, PhD. The observational study includes a cohort of 93,676 postmenopausal women, age 50 to 79, whom were enrolled from 1993 to 1998. In the study, 76,853 women completed a self-administered questionnaire at baseline providing information on their daily consumption of tea and coffee.

During analysis, the study team found that previous studies have shown an increased risk of rheumatoid arthritis associated with consumption of decaffeinated coffee, but no such association with caffeinated coffee intake. Many teas such as green tea, black tea, and oolong tea have been considered as antioxidants and perhaps reducing the risk of rheumatoid arthritis. However, several studies have suggested no relationship between tea consumption and rheumatoid arthritis. Other risk factors such as age, race/ethnicity, cigarette smoking, medical history, medication use, and other lifestyle behaviors may also be associated with an increased risk of rheumatoid arthritis.

There were 185 women who self-reported incident cases of rheumatoid arthritis. The results show that women with a history of nonherbal, nondecaffeinated tea consumption of any amount had an increased risk of developing rheumatoid arthritis during the first 3 years of observation in the Women’s Health Initiative Observation Study. The study results do not show any association between coffee intake and rheumatoid arthritis but there is a minimal increased risk of incident rheumatoid arthritis with caffeinated tea consumption.

The study authors are Diman Lamichlane, MD; Christopher Collins, MD; Florina Constantinescu, MD, PhD; Brian Walitt, MD; Mary Pettinger, MS; Christine Parks, PhD, MSPH; and Barbara Howard, PhD.

MedStar Investigators Evaluate Validity and Reliability of Diabetes Survival Skills Knowledge Test

MedStar Health investigators examined the validity and reliability of the KNOW Diabetes test, a survival skill knowledge test used to evaluate the impact of diabetes education and research interventions in their study “Validity and Reliability of a (Brief) Diabetes ‘Survival Skills’ Knowledge Test.” Diabetes self-management education support (DSMES) may be defined as essential education that facilitates the knowledge, skills, and abilities necessary for safe and effective sort-term diabetes self-care.

In the United States, there is a low rate of participation in diabetes self-management education support and lack of availability of short, easy-to-administer diabetes knowledge tests. This presents a need for a tool that can easily identify knowledge deficits to ensure the safety and effectiveness of diabetes self-care management among adults with type 2 diabetes mellitus where traditional diabetes self-management education support is not available. Managing diabetes is an important part of positive patient outcomes. The KNOW Diabetes knowledge test was developed with input from endocrinologists, certified diabetes educators, and patients in a US regional health care system. The test consists of questions from seven domains: nutrition and meal plan basics, blood glucose monitoring, glycemic targets, taking medications as prescribed, hyper- and hypoglycemia recognition and treatment, and when to seek medical help.

This study recruited 280 adults with T2DM for a two-phase research study. In phase one, the 19-question diabetes knowledge test was administered to assess feasibility. Following analysis of phase one data, three questions were removed from the knowledge test due to high difficulty and two questions on insulin storage were combined into a single question. The revised KNOW Diabetes survey contained 15 questions and was completed by 227 participants. Most participants were older than 65 years, and 65% reported having diabetes for more than five years. 70% of participants were African American.

The study results showed that patients who are older and have a lower level of education, have Medicaid or Medicare, and are without pain or numbness in the feet, scored significantly lower on the KNOW Diabetes test.  Test scores were higher among those who were younger, had a higher education level had a longer duration of diabetes and were non-Medicare or Medicaid insured.

The KNOW Diabetes knowledge test is intended to identify knowledge deficits in diabetes self-management survival skills and the study results prove the validity and reliability of the test for use in a variety of nondiabetic specialty care settings as well as in the clinical care setting.

The collaborative research team included Gretchen Youssef, MS, RD, CDE; Edward H. Ip, PhD; Michelle Magee, MD, MBBCh, BAO, LRCPSI; Shyh-Huei Chen, PhD; Amisha Wallia, MD, MS; Teresa Pollack, MS; Emilie Touma; Clayton Bourges, MS; Lynne Brecker, BSN, RN, CDE from the MedStar Diabetes Institute.

Collaborative Research from MedStar Investigators Evaluates Early Laser Treatment in Surgical Scar Minimization

Recently published research from MedStar Washington Hospital Center, MedStar Health Research Institute, Firefighters’ Burn and Surgical Research Laboratory, MedStar Georgetown University Hospital, and Georgetown University School of Medicine investigated the efficacy of lasers to minimize surgical scars when applied less than one month after operation. Laser scar therapies aim to treat undesirable results post operation. Prevention of visible scars is preferred over treatment, and studies examining the use of lase scar therapies at earlier stages have shown improved results.

The study “Effectiveness of Early Laser Treatment in Surgical Scar Minimization: A Systematic Review and Meta-analysis” examined previously published literature in order to evaluate the efficacy of laser modalities in minimizing the undesirable characteristics of primary closed full-thickness surgical scars less than one month after operation. The literature review encompassed 8 articles in the systematic review and 4 in the meta-analysis.

The primary outcome of the study was the quantitative statistical review of the available data generated from randomized controlled trials determining the efficacy of early laser therapies applied less than 1 month after operation to minimize surgical scars. Based on the data, the analysis showed statistically significant therapeutic effect (p < .05). Due to the nature of the research included in this analysis (a diverse set of applications and usage), this statistical finding can offer evidence for the use of laser modalities as a whole under this indication.

The secondary outcome was a qualitative review where the validity of most individual studies included were determined to be “fair”. However, half of the studies included in the statistical review received “good” ratings.

Within the analyzed studies, there were inconsistent conclusions of studies using pulsed-dye laser systems. This observation was based on the varied use of purpuric versus non-purpuric laser settings. Only non-purpuric settings have been found to be reliably effective, whereas purpuric settings have failed to show efficacy. The research team recommends the use of non-pupuric settings when treating early scars, as this method is also desirable to patients.

In summary, the ability of lasers to achieve significant improvement after one session is ideal, alleviating the burden of repeat visits and providing a cost-effective means of minimizing scars. However, multiple scar treatments are often recommended for optimal results. Most patients prefer early treatment, as the scars are more amendable to treatment instead of waiting until they are hard, thick, and difficult to penetrate. The outcome supports the efficacy of lasers in minimizing primarily closed surgical scars when treated less than one month after surgery.

The study team included Rhett A. Kent, MD, Jeffrey Shupp, MD, Stephen Fernandez, MPH, Nick Prindeze, BS; and Cynthia M.C. DeKlotz, MD.
