Item Open Access A case study of inclusion of rural populations in research: Implications for science and health equity.(Clinical and translational science, 2024-08) Noonan, Devon; Lam, Wendy KK; Goodrich, James; Sullivan, Sydney; Bentley-Edwards, Keisha; Koeberl, Dwight; Palipana, Anushka; McClernon, F JosephPrior research highlights that rural populations have been historically underrepresented/excluded from clinical research. The primary objective of this study was to describe the inclusion of rural populations within our research enterprise using Clinical Research Management System demographic information at a large academic medical center in the Southeast. This was a cross-sectional study using participant demographic information for all protocols entered into our Clinical Research Management System between May 2018 and March 2021. Descriptive statistics were used to analyze the representation of rural and non-rural participants and demographic breakdown by age, sex, race, and ethnicity for our entire enterprise and at the state level. We also compared Material Community Deprivation Index levels between urban and rural participants. Results indicated that 19% of the research population was classified as rural and 81% as non-rural for our entire sample, and 17.5% rural and 82.5% urban for our state-level sample. There were significant differences in race, sex, and age between rural and non-rural participants and Material Community Deprivation Indices between rural and non-rural participants. Lessons learned and recommendations for increasing the inclusion of rural populations in research are discussed.Item Open Access A cross-site, comparative effectiveness study of an integrated HIV and substance use treatment program.(AIDS Patient Care STDS, 2010-10) Proeschold-Bell, Rae Jean; Heine, Amy; Pence, Brian Wells; McAdam, Keith; Quinlivan, Evelyn ByrdCo-occurrence of HIV and substance abuse is associated with poor outcomes for HIV-related health and substance use. Integration of substance use and medical care holds promise for HIV patients, yet few integrated treatment models have been reported. Most of the reported models lack data on treatment outcomes in diverse settings. This study examined the substance use outcomes of an integrated treatment model for patients with both HIV and substance use at three different clinics. Sites differed by type and degree of integration, with one integrated academic medical center, one co-located academic medical center, and one co-located community health center. Participants (n=286) received integrated substance use and HIV treatment for 12 months and were interviewed at 6-month intervals. We used linear generalized estimating equation regression analysis to examine changes in Addiction Severity Index (ASI) alcohol and drug severity scores. To test whether our treatment was differentially effective across sites, we compared a full model including site by time point interaction terms to a reduced model including only site fixed effects. Alcohol severity scores decreased significantly at 6 and 12 months. Drug severity scores decreased significantly at 12 months. Once baseline severity variation was incorporated into the model, there was no evidence of variation in alcohol or drug score changes by site. Substance use outcomes did not differ by age, gender, income, or race. This integrated treatment model offers an option for treating diverse patients with HIV and substance use in a variety of clinic settings. Studies with control groups are needed to confirm these findings.Item Open Access Exploring the impact of tablet computers on medical training at an academic medical center.(J Med Libr Assoc, 2013-04) Perez, Bradford A; von Isenburg, Megan A; Yu, Miao; Tuttle, Brandi D; Adams, Martha BItem Open Access Hand hygiene noncompliance and the cost of hospital-acquired methicillin-resistant Staphylococcus aureus infection.(Infect Control Hosp Epidemiol, 2010-04) Cummings, Keith L; Anderson, Deverick J; Kaye, Keith SBACKGROUND: Hand hygiene noncompliance is a major cause of nosocomial infection. Nosocomial infection cost data exist, but the effect of hand hygiene noncompliance is unknown. OBJECTIVE: To estimate methicillin-resistant Staphylococcus aureus (MRSA)-related cost of an incident of hand hygiene noncompliance by a healthcare worker during patient care. DESIGN: Two models were created to simulate sequential patient contacts by a hand hygiene-noncompliant healthcare worker. Model 1 involved encounters with patients of unknown MRSA status. Model 2 involved an encounter with an MRSA-colonized patient followed by an encounter with a patient of unknown MRSA status. The probability of new MRSA infection for the second patient was calculated using published data. A simulation of 1 million noncompliant events was performed. Total costs of resulting infections were aggregated and amortized over all events. SETTING: Duke University Medical Center, a 750-bed tertiary medical center in Durham, North Carolina. RESULTS: Model 1 was associated with 42 MRSA infections (infection rate, 0.0042%). Mean infection cost was $47,092 (95% confidence interval [CI], $26,040-$68,146); mean cost per noncompliant event was $1.98 (95% CI, $0.91-$3.04). Model 2 was associated with 980 MRSA infections (0.098%). Mean infection cost was $53,598 (95% CI, $50,098-$57,097); mean cost per noncompliant event was $52.53 (95% CI, $47.73-$57.32). A 200-bed hospital incurs $1,779,283 in annual MRSA infection-related expenses attributable to hand hygiene noncompliance. A 1.0% increase in hand hygiene compliance resulted in annual savings of $39,650 to a 200-bed hospital. CONCLUSIONS: Hand hygiene noncompliance is associated with significant attributable hospital costs. Minimal improvements in compliance lead to substantial savings.Item Open Access Optimizing donor selection for public cord blood banking: influence of maternal, infant, and collection characteristics on cord blood unit quality.(Transfusion, 2014-02) Page, Kristin M; Mendizabal, Adam; Betz-Stablein, Brigid; Wease, Stephen; Shoulars, Kevin; Gentry, Tracy; Prasad, Vinod K; Sun, Jessica; Carter, Shelly; Balber, Andrew E; Kurtzberg, JoanneBackground
Banked unrelated donor umbilical cord blood (CB) has improved access to hematopoietic stem cell transplantation for patients without a suitably matched donor. In a resource-limited environment, ensuring that the public inventory is enriched with high-quality cord blood units (CBUs) addressing the needs of a diverse group of patients is a priority. Identification of donor characteristics correlating with higher CBU quality could guide operational strategies to increase the yield of banked high-quality CBUs.Study design and methods
Characteristics of 5267 CBUs donated to the Carolinas Cord Blood Bank, a public bank participating in the National Cord Blood Inventory, were retrospectively analyzed. Eligible CBUs, collected by trained personnel, were processed using standard procedures. Routine quality and potency metrics (postprocessing total nucleated cell count [post-TNCC], CD34+, colony-forming units [CFUs]) were correlated with maternal, infant, and collection characteristics.Results
High-quality CBUs were defined as those with higher post-TNCC (>1.25 × 10(9)) with CD34+ and CFUs in the upper quartile. Factors associated with higher CD34+ or CFU content included a shorter interval from collection to processing (<10 hr), younger gestational age (34-37 weeks; CD34+ and CFUs), Caucasian race, higher birthweight (>3500 g), and larger collection volumes (>80 mL).Conclusions
We describe characteristics identifying high-quality CBUs, which can be used to inform strategies for CBU collection for public banks. Efforts should be made to prioritize collections from larger babies born before 38 weeks of gestation. CBUs should be rapidly transported to the processing laboratory. The lower quality of CBUs from non-Caucasian donors highlights the challenges of building a racially diverse public CB inventory.Item Open Access Prevalence of renal anomalies after urinary tract infections in hospitalized infants less than 2 months of age.(J Perinatol, 2010-04) Nowell, L; Moran, C; Smith, PB; Seed, P; Alexander, BD; Cotten, CM; Wiener, JS; Benjamin Jr, DKOBJECTIVE: Our aim was to determine the incidence of anatomical abnormalities after a urinary tract infection (UTI) in infants <2 months of age hospitalized in the neonatal intensive care unit (NICU). STUDY DESIGN: This was a retrospective, single-center cohort study of infants <2 months of age in the NICU with a UTI and documented renal imaging. RESULT: We identified 141 infants with UTIs. The mean gestational age and birth weight were 28 weeks and 1254 g, respectively. The most commonly identified pathogen was coagulase-negative Staphylococcus (28%, 44 of 156). A major abnormality was found on at least one imaging study for 4% (5 of 118) of infants. Major abnormalities were noted on 4% (5 of 114) of renal ultrasounds and 2% (2 of 82) of voiding cystourethrography examinations. CONCLUSION: Among infants in the NICU <2 months of age at the time of a UTI, the prevalence of major anatomical abnormalities is <5%.Item Open Access Reinvigorating pediatric care in an academic family medicine practice.(Family medicine, 2014-02) Page, Cristen; Carlough, Martha C; Lam, Yee; Steiner, JuleaBackground and objectives
Primary care access is critical for all populations, and family physicians remain a vital link to pediatric care, especially for rural/underserved areas and adolescents. Pediatric visits to family physicians have declined nationally, a trend also noted at the University of North Carolina (UNC) Family Medicine Center (FMC). Academic FMCs are challenged with maintaining their pediatric population in a competitive environment and providing excellent pediatric training to prepare residents to care for children. We investigated potential factors impacting pediatric visits with a goal of reversing this trend. We developed a 360-degree approach to examine and reinvigorate pediatric care and training in our practice.Methods
To determine which aspects of our practice made pediatric care challenging, we conducted focus groups with parents of former and current FMC pediatric practices. We used billing data to assess pediatric patient volume and performed chart audits to examine preventive health visits, immunizations, and developmental screening. We anonymously contacted local family medicine and pediatric practices to compare services offered in their practice versus ours. Resident in-training exam scores and graduate surveys were reviewed to assess our pediatric training.Results
Based on our evaluation, we identified and implemented improvements in the areas of clinical quality interventions, provider/education competency, and community marketing/relationships.Conclusions
A longitudinal evaluation and quality improvement initiative positively impacted our pediatric practice and training. The 360-degree approach of quality improvement may be useful for other academic family practices that are challenged with pediatric volume.Item Open Access Stakeholder Perspectives on Creating and Maintaining Trust in Community-Academic Research Partnerships.(Health education & behavior : the official publication of the Society for Public Health Education, 2017-02) Frerichs, Leah; Kim, Mimi; Dave, Gaurav; Cheney, Ann; Hassmiller Lich, Kristen; Jones, Jennifer; Young, Tiffany L; Cene, Crystal W; Varma, Deepthi S; Schaal, Jennifer; Black, Adina; Striley, Catherine W; Vassar, Stefanie; Sullivan, Greer; Cottler, Linda B; Brown, Arleen; Burke, Jessica G; Corbie-Smith, GiselleCommunity-academic research partnerships aim to build stakeholder trust in order to improve the reach and translation of health research, but there is limited empirical research regarding effective ways to build trust. This multisite study was launched to identify similarities and differences among stakeholders' perspectives of antecedents to trust in research partnerships. In 2013-2014, we conducted a mixed-methods concept mapping study with participants from three major stakeholder groups who identified and rated the importance of different antecedents of trust on a 5-point Likert-type scale. Study participants were community members ( n = 66), health care providers ( n = 38), and academic researchers ( n = 44). All stakeholder groups rated "authentic communication" and "reciprocal relationships" the highest in importance. Community members rated "communication/methodology to resolve problems" ( M = 4.23, SD = 0.58) significantly higher than academic researchers ( M = 3.87, SD = 0.67) and health care providers ( M = 3.89, SD = 0.62; p < .01) and had different perspectives regarding the importance of issues related to "sustainability." The importance of communication and relationships across stakeholders indicates the importance of colearning processes that involve the exchange of knowledge and skills. The differences uncovered suggest specific areas where attention and skill building may be needed to improve trust within partnerships. More research on how partnerships can improve communication specific to problem solving and sustainability is merited.Item Open Access Tb in a global health exchange program.(J Gen Intern Med, 2012-01) Decamp, Matthew; Crump, John A; Rodriguez, Joce; Richardson, Gene; Barry, Michele; Sugarman, JeremyItem Open Access Torsemide versus furosemide in heart failure patients: insights from Duke University Hospital.(J Cardiovasc Pharmacol, 2015-05) Mentz, Robert J; Buggey, Jonathan; Fiuzat, Mona; Ersbøll, Mads K; Schulte, Phillip J; DeVore, Adam D; Eisenstein, Eric L; Anstrom, Kevin J; OʼConnor, Christopher M; Velazquez, Eric JFurosemide has historically been the primary loop diuretic in heart failure patients despite data suggesting potential advantages with torsemide. We used the Duke Echocardiography Lab Database to investigate patients admitted with heart failure to Duke Hospital from 2000 to 2010 who were discharged on either torsemide or furosemide. We described baseline characteristics based on discharge diuretic and assessed the relationship with all-cause mortality through 5 years. Of 4580 patients, 86% (n = 3955) received furosemide and 14% (n = 625) received torsemide. Patients receiving torsemide were more likely to be female and had more comorbidities compared with furosemide-treated patients. Survival was worse in torsemide-treated patients [5-year Kaplan-Meier estimated survival of 41.4% (95% CI: 36.7-46.0) vs. 51.5% (95% CI: 49.8-53.1)]. After risk adjustment, torsemide use was no longer associated with increased mortality (hazard ratio 1.16; 95% CI: 0.98-1.38; P = 0.0864). Prospective trials are needed to investigate the effect of torsemide versus furosemide because of the potential for residual confounding.Item Open Access Using electronic health records data to assess comorbidities of substance use and psychiatric diagnoses and treatment settings among adults.(Journal of psychiatric research, 2013-04) Wu, Li-Tzy; Gersing, Kenneth R; Swartz, Marvin S; Burchett, Bruce; Li, Ting-Kai; Blazer, Dan GTo examine prevalences of substance use disorders (SUD) and comprehensive patterns of comorbidities among psychiatric patients ages 18-64 years (N = 40,099) in an electronic health records (EHR) database.DSM-IV diagnoses among psychiatric patients in a large university system were systematically captured: SUD, anxiety (AD), mood (MD), personality (PD), adjustment, childhood-onset, cognitive/dementia, dissociative, eating, factitious, impulse-control, psychotic (schizophrenic), sexual/gender identity, sleep, and somatoform diagnoses. Comorbidities and treatment types among patients with a SUD were examined.Among all patients, 24.9% (n = 9984) had a SUD, with blacks (35.2%) and Hispanics (32.9%) showing the highest prevalence. Among patients with a SUD, MD was prevalent across all age groups (50.2-56.6%). Patients aged 18-24 years had elevated odds of comorbid PD, adjustment, childhood-onset, impulse-control, psychotic, and eating diagnoses. Females had more PD, AD, MD, eating, and somatoform diagnoses, while males had more childhood-onset, impulse-control, and psychotic diagnoses. Blacks had greater odds than whites of psychotic and cognitive/dementia diagnoses, while whites exhibited elevated odds of PA, AD, MD, childhood-onset, eating, somatoform, and sleep diagnoses. Women, blacks, and Native American/multiple-race adults had elevated odds of using inpatient treatment; men, blacks, and Hispanics had increased odds of using psychiatric emergency care. Comorbid MD, PD, adjustment, somatoform, psychotic, or cognitive/dementia diagnoses increased inpatient treatment.Patients with a SUD, especially minority members, use more inpatient or psychiatric emergency care than those without. Findings provide evidence for research on understudied diagnoses and underserved populations in the real-world clinical settings.
