Background/purposeNurse managers (NMs) play an important role promoting evidence-based practice (EBP) on clinical units within hospitals. However, there is a dearth of research focused on NM perspectives about institutional contextual factors to support the goal of EBP on the clinical unit. The purpose of this article is to identify contextual factors described by NMs to drive change and facilitate EBP at the unit level, comparing and contrasting these perspectives across nursing units.MethodsThis study employed a qualitative descriptive design using interviews with nine NMs who were participating in a large effectiveness study. To stratify the sample, NMs were selected from nursing units designated as high or low performing based on implementation of EBP interventions, scores on the Meyer and Goes research use scale, and fall rates. Descriptive content analysis was used to identify themes that reflect the complex nature of infrastructure described by NMs and contextual influences that supported or hindered their promotion of EBP on the clinical unit.ResultsNMs perceived workplace culture, structure, and resources as facilitators or barriers to empowering nurses under their supervision to use EBP and drive change. A workplace culture that provides clear communication of EBP goals or regulatory changes, direct contact with CEOs, and clear expectations supported NMs in their promotion of EBP on their units. High-performing unit NMs described a structure that included nursing-specific committees, allowing nurses to drive change and EBP from within the unit. NMs from high-performing units were more likely to articulate internal resources, such as quality-monitoring departments, as critical to the implementation of EBP on their units. This study contributes to a deeper understanding of institutional contextual factors that can be used to support NMs in their efforts to drive EBP changes at the unit level.

The purpose of this paper is to elaborate upon barriers to research participation by older adults at end-of-life. We focus on the hospice setting and classify barriers to research participation into six domains:1) societal attitudes towards death; 2) research procedures; 3) health care organizations; 4) agency staff; 5) patients’ families and caregivers; and 6) patient characteristics. We characterize particular participation issues, uncertainties in participation for individuals with advanced illness, infringements upon patient self-determination, as well as, potential solutions to these research challenges. Our observation of the complex palliative context included the realization that a singular change would not have large enough impact. We concluded that simultaneous with the need to expand the research base addressing the needs of dying persons is a need to understand the challenges of implementing research projects with older persons at end-of-life.

Background Obesity is a common source of artifact on conventional SPECT myocardial perfusion imaging (MPI). We evaluated image quality and diagnostic performance of high-efficiency (HE) cadmium-zinc-telluride (CZT) parallel-hole SPECT-MPI for coronary artery disease (CAD) in obese patients. Methods and Results 118 consecutive obese patients at 3 centers (BMI 43.6±8.9 kg/m2, range 35–79.7 kg/m2) had upright/supine HE-SPECT and ICA >6 months (n=67) or low-likelihood of CAD (n=51). Stress quantitative total perfusion deficit (TPD) for upright (U-TPD), supine (S-TPD) and combined acquisitions (C-TPD) was assessed. Image quality (IQ; 5=excellent; <3 nondiagnostic) was compared among BMI 35–39.9 (n=58), 40–44.9 (n=24) and ≥45 (n=36) groups. ROC-curve area for CAD detection (≥50% stenosis) for U-TPD, S-TPD, and C-TPD were 0.80, 0.80, and 0.87, respectively. Sensitivity/specificity was 82%/57% for U-TPD, 74%/71% for S-TPD, and 80%/82% for C-TPD. C-TPD had highest specificity (P=.02). C-TPD normalcy rate was higher than U-TPD (88% vs. 75%, P=.02). Mean IQ was similar among BMI 35–39.9, 40–44.9 and ≥45 groups [4.6 vs. 4.4 vs. 4.5, respectively (P=.6)]. No patient had a non-diagnostic stress scan. Conclusions In obese patients, HE-SPECT MPI with dedicated parallel-hole collimation demonstrated high image quality, normalcy rate, and diagnostic accuracy for CAD by quantitative analysis of combined upright/supine acquisitions.

Serial SPECT MPI demonstrated improved stress myocardial perfusion in 48% of patients treated for six months with pravastatin. Time course of improved myocardial perfusion during pravastatin therapy is delayed compared to lipids. Direction and magnitude of changes in the myocardial perfusion vary and do not correlate closely with improvements in lipids.

IV aminophylline and IV caffeine provide rapid, safe reversal of regadenoson-induced adverse effects during SPECT MPI. Oral caffeine appeared similarly effective for CR but not for the combined CR + PRE. Our results suggest PO caffeine may be an effective initial strategy for reversal of regadenoson, but IV aminophylline or IV caffeine should be available to optimize symptom reversal as needed.

Significant increases in the carrying of emergency contraception suggest the policy did succeed in increasing access. Despite this, barriers to access exist. Further research should explore why pharmacies might not carry emergency contraception.

The purpose of this article was to describe nursing practices (e.g., assessment, interventions) around fall prevention, as perceived by nurse managers in adult, medical-surgical nursing units. One hundred forty nurse managers from 51 hospitals from across the United States participated. Descriptive frequencies are used to describe nurse manager responses. The most commonly used fall risk assessment tool was the Morse Fall Risk Assessment Tool (40%). The most common fall prevention interventions included bed alarms (90%), rounds (70%), sitters (68%), and relocating the patient closer to the nurses' station (56%). Twenty-nine percent of nurse managers identified physical restraints as an intervention to prevent falls whereas only 10% mentioned ambulation. No nurse manager identified that RN hours per patient-day were adjusted to prevent falls or fall-related injuries. More work is needed to build systems that ensure evidence-based nursing interventions are consistently applied in acute care.
