An Organizational Quality Improvement Project Exploring Diversity, Equity, and Inclusion Opportunities
Aims: The purpose of this participatory action quality improvement project was to identify challenges and member-driven solutions to enhance diversity, equity, and inclusion (DEI) in a regional nursing research society (RNRS).
Methods: This project adhered to a quality improvement (QI) framework and drew on strategies used in participatory action research to collect data on member-identified organizational practices that support and/or limit DEI within the RNRS, and member-generated solutions to enhance DEI within the society. The QI team consisted of RNRS members serving on a DEI Task Force and members with qualitative methods expertise. The team conducted focus groups during the society’s annual meeting and collected quantitative and qualitative data using a cross-sectional survey sent to all society members following the annual meeting.
Results: Preliminary findings of this project in progress (PIP) indicate membership willingness to identify DEI issues and potential organizational solutions. Preliminary focus group data demonstrated members’ desires to encourage and support underrepresented members of the society. Potential solutions suggested by membership included creating mechanisms for financial support of underrepresented current/prospective members, increasing transparency in executive board decision-making, and creating more robust mechanisms for new member orientation and existing member professional development through a formal mentorship program.
Conclusions: This PIP provides an exemplar of nursing research societies’ potential capacity to engage members in efforts to enhance organizational DEI. Efforts to create regional nursing research societies that are more inclusive and more accurately reflect the broader population is an important first step in supporting research on social and structural determinants of health
Differences among physical activity actigraphy algorithms in three chronic illness populations
Objectives: In three chronic illness populations and in a combined sample, we assessed differences in two algorithms to determine wear time (WT%) and four algorithms to determine: Kilocalories, light physical activity (PA), moderate-to-vigorous PA (MVPA), and metabolic equivalents (METs).
Methods: Data were collected from 29 people living with HIV (PLHIV), 27 participants recovering from a cardiac event, and 15 participants with hypertension (HTN). Participants wore the ActiGraphTM wGT3X-BT for > 3 days on their hip. Analysis of variance (ANOVA) was used to assess differences among the algorithms.
Results: No differences were found between the two algorithms to assess WT% or among the four algorithms to assess kilocalories in each of the chronic illness populations or in the combined sample. Significant differences were found among the four algorithms for light PA (p < .001) and METs (p < .001) in each chronic illness population and in the combined sample. MVPA was significantly different among the four algorithms in the PLHIV (p=.007) and in the combined sample (p < .001), but not in the cardiac (p=.064) or HTN samples (p=.200).
Discussion: Our findings indicate that the choice of algorithm does make a difference in PA determination. Differences in algorithms should be considered when comparing PA across different chronic illness populations.This work was supported by the National Institute of Nursing Research (grant numbers P30NR015326 and T32NR015433)
Clinical Outcomes by Race and Ethnicity in the Systolic Blood Pressure Intervention Trial (SPRINT): A Randomized Clinical Trial
BACKGROUND:
The Systolic Blood Pressure Intervention Trial (SPRINT) showed that targeting a systolic blood pressure (SBP) of ≤ 120 mm Hg (intensive treatment) reduced cardiovascular disease (CVD) events compared to SBP of ≤ 140 mm Hg (standard treatment); however, it is unclear if this effect is similar in all racial/ethnic groups.
METHODS:
We analyzed SPRINT data within non-Hispanic White (NHW), non-Hispanic Black (NHB), and Hispanic subgroups to address this question. High-risk nondiabetic hypertensive patients (N = 9,361; 30% NHB; 11% Hispanic) 50 years and older were randomly assigned to intensive or standard treatment. Primary outcome was a composite of the first occurrence of a myocardial infarction, acute coronary syndrome, stroke, decompensated heart failure, or CVD death.
RESULTS:
Average postbaseline SBP was similar among NHW, NHB, and Hispanics in both treatment arms. Hazard ratios (HRs) (95% confidence interval) (intensive vs. standard treatment groups) for primary outcome were 0.70 (0.57–0.86), 0.71 (0.51–0.98), 0.62 (0.33–1.15) (interaction P value = 0.85) in NHW, NHB, and Hispanics. CVD mortality HRs were 0.49 (0.29–0.81), 0.77 (0.37–1.57), and 0.17 (0.01–1.08). All-cause mortality HRs were 0.61 (0.47–0.80), 0.92 (0.63–1.35), and 1.58 (0.73–3.62), respectively. A test for differences among racial/ethnic groups in the effect of treatment assignment on all-cause mortality was not significant (Hommel-adjusted P value = 0.062) after adjustment for multiple comparisons.
CONCLUSION:
Targeting a SBP goal of ≤ 120 mm Hg compared to ≤ 140 mm Hg led to similar SBP control and was associated with similar benefits and risks among all racial ethnic groups, though NHBs required an average of ~0.3 more medications
Effects of a high-dose 24-h infusion of tranexamic acid on death and thromboembolic events in patients with acute gastrointestinal bleeding (HALT-IT): an international randomised, double-blind, placebo-controlled trial
Background: Tranexamic acid reduces surgical bleeding and reduces death due to bleeding in patients with trauma.
Meta-analyses of small trials show that tranexamic acid might decrease deaths from gastrointestinal bleeding. We
aimed to assess the effects of tranexamic acid in patients with gastrointestinal bleeding.
Methods: We did an international, multicentre, randomised, placebo-controlled trial in 164 hospitals in 15 countries.
Patients were enrolled if the responsible clinician was uncertain whether to use tranexamic acid, were aged above the
minimum age considered an adult in their country (either aged 16 years and older or aged 18 years and older), and
had significant (defined as at risk of bleeding to death) upper or lower gastrointestinal bleeding. Patients were
randomly assigned by selection of a numbered treatment pack from a box containing eight packs that were identical
apart from the pack number. Patients received either a loading dose of 1 g tranexamic acid, which was added to
100 mL infusion bag of 0·9% sodium chloride and infused by slow intravenous injection over 10 min, followed by a
maintenance dose of 3 g tranexamic acid added to 1 L of any isotonic intravenous solution and infused at 125 mg/h
for 24 h, or placebo (sodium chloride 0·9%). Patients, caregivers, and those assessing outcomes were masked to
allocation. The primary outcome was death due to bleeding within 5 days of randomisation; analysis excluded patients
who received neither dose of the allocated treatment and those for whom outcome data on death were unavailable.
This trial was registered with Current Controlled Trials, ISRCTN11225767, and ClinicalTrials.gov, NCT01658124.
Findings: Between July 4, 2013, and June 21, 2019, we randomly allocated 12 009 patients to receive tranexamic acid
(5994, 49·9%) or matching placebo (6015, 50·1%), of whom 11 952 (99·5%) received the first dose of the allocated
treatment. Death due to bleeding within 5 days of randomisation occurred in 222 (4%) of 5956 patients in the
tranexamic acid group and in 226 (4%) of 5981 patients in the placebo group (risk ratio [RR] 0·99, 95% CI 0·82–1·18).
Arterial thromboembolic events (myocardial infarction or stroke) were similar in the tranexamic acid group and
placebo group (42 [0·7%] of 5952 vs 46 [0·8%] of 5977; 0·92; 0·60 to 1·39). Venous thromboembolic events (deep vein
thrombosis or pulmonary embolism) were higher in tranexamic acid group than in the placebo group (48 [0·8%] of
5952 vs 26 [0·4%] of 5977; RR 1·85; 95% CI 1·15 to 2·98).
Interpretation: We found that tranexamic acid did not reduce death from gastrointestinal bleeding. On the basis of our
results, tranexamic acid should not be used for the treatment of gastrointestinal bleeding outside the context of a
randomised trial
Designing a Cocreated Intervention with African American Older Adults for Hypertension Self-Management
Hypertension is a lifelong disease that requires self-management. Additionally, there are disparities in hypertension self-management that disproportionately affect African Americans. Interventions designed in collaboration with older adults have the potential to improve hypertension self-management. The purpose of this design paper is to describe the process in which African American older adults and nurse researchers cocreated an intervention to address stress in the self-management of hypertension. A semistructured interview guide was used to elicit feedback on self-management behaviors to cocreate an intervention with the participants. Participants provided constant iterative feedback on the design used for the intervention. Participants prioritized the content and mode of delivery. African American older adults with hypertension (N=31; 87% women) participated in two focus group sessions. The primary stressors identified by the group that influenced their blood pressure self-management were as follows: (a) measuring blood pressure and using home blood pressure monitors; (b) difficulty communicating with family and friends; (c) sleep management and pain at night; and (d) healthy eating. Based on the participants’ feedback, we created four biweekly (2-hour) group sessions that incorporated their suggestions and addressed their concerns. Health care providers can use this technique to engage African American older adults in participant-centered hypertension self-management

The impact of central IRB's on informed consent readability and trial adherence in SPRINT
Federal agencies have encouraged the use of central institutional review boards (CIRBs) for multi-site clinical trials. There is limited evidence supporting the use of CIRBs. Our aim is to evaluate how SPRINT sites regulated by CIRBs performed regarding informed consent readability and participant trial adherence compared to those regulated by local IRBs.
We conducted a cohort study using the SPRINT clinical trial. We collected the IRB of record from the stamped and approved 2012 informed consents from each of the sites. We defined CIRB as an IRB for more than one SPRINT site. Our outcomes were informed consent readability measured using the Flesch-Kincaid readability scale and trial adherence defined as a loss to follow-up, consent withdrawal, and missed last 3-month visit.
Sixty-one percent of all SPRINT sites used a CIRB as their IRB of record. The adjusted mean grade reading level for CIRB consents was 13.4 (95% CI 12.6–13.8) compared to 12.3 (95% CI 12.1–13.1) for non CIRB consents (p = 0.07). CIRB sites had similar rates of withdrawal of consent and loss to follow-up as non-CIRB sites; subjects missing the last appointment of the study were more likely to come from sites regulated by a CIRB. The Veterans Affairs CIRB had the lowest rate of withdrawal of consent (1.9%) and the lowest rate of missed appointments (1.9%) among CIRBs.
Niether CIRB-regulated sites nor IRB regulated sites enforce the recommended readability level of the informed consent documents. Sites regulated by both IRBs had similar participant trial adherence
Measuring Mental Workload and Brain Dynamics in Prosthesis Motor Learning over Multi-Session Practice
Gemstone Team REACHThe capability of humans to adapt their motor behavior and learn new motor skills is critical
to interact with their changing environment as well as for integration with new machine interfaces,
such as assistive technology (Casadio, Ranganathan, & Mussa-Ivaldia, 2012; Kitago & Krakauer,
2013; Mussa-Ivaldi et al., 2011). Such learning capability depends on the recruitment of cognitivemotor
resources (Wickens, 2002). Mental workload (MWL), which is an important component in
understanding learning, can be defined as the relationship between the deployment of neural
resources and imposed task demands (Sharples & Megaw, 2005; Young et al., 2015). Although a
large body of work has examined the behavior and cortical dynamics underlying the motor learning
processes, most of this prior effort generally did not examine changes in mental workload through
multiple practice sessions and did not consider individuals with upper limb (UL) loss (Marchand,
de Graaf, & Jarrassé, 2021; Park & Zahabi, 2022).
In this work, UL amputees were approximated by considering healthy individuals using
bypass prostheses (Bloomer, Wang, & Kontson, 2018; Wang et al., 2021). Based on the work by
Bloomer and Wang, able-bodied individuals can serve as a reasonable proxy for amputees while
using these bypass prostheses. From a methodological standpoint, the use of human-body
interfaces such as a bypass prosthesis is interesting since it requires participants to acquire a novel
and unusual sensorimotor mapping, mitigating the influence of prior motor experiences and
ultimately offering a fairly unbiased learning paradigm (Casadio, Ranganathan, & Mussa-Ivaldia,
2012; Mussa-Ivaldi et al., 2011). Thus, we employed this approach here, along with
electroencephalography (EEG), which was used to assess the cortical dynamics as participants
completed the learning task in order to objectively assess mental workload. In addition, surveys
were employed to subjectively assess the level of workload perceived by the participants along with performance (e.g., time, smoothness, number of blocks transported within a fixed time period)
collected via an inertial measuring unit.
Overall, the aim of this research was to examine the concomitant changes in performance
(e.g., number of blocks transported within a fixed time period) and in mental workload (by means
of surveys and the cortical dynamics indexed by EEG) that occur when healthy individuals learn
to operate a bypass prosthetic device via multi-session practice to perform a variety of motor tasks
of daily living. This work can inform not only the human cognitive-motor processes underlying
mental workload and performance during learning but also, to some degree, the
rehabilitation/training of UL amputees, as well as the design and evaluation of prosthetic devices
Baseline characteristics of African Americans in the Systolic Blood Pressure Intervention Trial
The Systolic Blood Pressure Intervention Trial (SPRINT) will compare treatment to a systolic blood pressure goal of <120 mmHg to treatment to the currently recommended goal of <140 mmHg for effects on incident cardiovascular, renal, and neurologic outcomes including cognitive decline. OBJECTIVES: The objectives of this analysis are to compare baseline characteristics of African American (AA) and non-AA SPRINT participants and explore factors associated with uncontrolled blood pressure (BP) by race. METHODS: SPRINT enrolled 9,361 hypertensive participants over age 50. This cross-sectional analysis examines sociodemographics, baseline characteristics, and study measures among AAs compared to non-AAs. RESULTS: AAs made up 31% of participants. AAs (compared to non-AAs) were younger and less frequently male, had less education, and were more likely uninsured or covered by Medicaid. In addition, AAs scored lower on the cognitive screening test when compared to non-AAs. Multivariable logistic regression analysis found BP control rates to <140/90 mmHg were higher for AAs who were male, had higher number of chronic diseases, were on diuretic treatment, and had better medication adherence. CONCLUSION: SPRINT is well poised to examine the effects of SBP targets on clinical outcomes as well as predictors influencing BP control in AAs
