ABSTRACT

OBJECTIVE: To examine the extent to which Veterans Health Administration (VHA) Patient-Aligned Care Team (PACT) members have a shared understanding/ agreement upon and enact responsibilities within the team. BACKGROUND: The PACT model focuses on team-based care management. However, lack of a shared understanding of team-based care management roles and responsibilities makes system-wide implementation a challenge. METHODS: Quantitative and qualitative analysis of national survey data collected in 2022 from primary care personnel working in a VHA-affiliated primary care facility. RESULTS: Significant discrepancies exist in responses about what core team members say they do and what others perceive they should be doing, indicating either a lack of agreement, knowledge, or training about what core team members should do. CONCLUSIONS: Successful implementation of a team-based model requires adequate support and training for teamwork including shared mental models to work according to their clinical competency. Clear guidance and communication of expectations are critical for role clarity.

ABSTRACT

BACKGROUND: Working for extended hours in a physically and mentally demanding profession has subjected nurses to occupational fatigue. Limited evidence exists about nurse fatigue and alertness changes throughout shift work and their relationship with medication errors and near misses. PURPOSE: The purposes of this study were to: (1) assess the relationship between nurses' fatigue and alertness, (2) evaluate nurses' fatigue and alertness changes throughout their shift, and (3) examine the relationship between nurses' fatigue, alertness, and medication errors and near misses. METHODS: This prospective study is part of a larger mixed-method study. Fatigue and alertness data from 14 work and non-workdays were collected from a convenience sample of 90 nurses. A wearable actigraph (ReadibandTM) was used to measure alertness, while ecological momentary assessment (EMA) using text messaging was used to measure nurses' fatigue. RESULTS: A 1-unit increase in fatigue was associated with a 1.06-unit reduction in nurses' alertness score (ß = -1.06, 95% CI: [-1.33, -0.78], p < .01). Night-shift nurses experienced a 31-point reduction in alertness from the start to the end of the work shift. Nurses' fatigue, but not alertness, was associated with medication errors and near misses (OR = 1.26, 95% CI [1.07, 1.48], p = .01). CONCLUSION: Initiating fatigue mitigation measures during mid-shift, especially for night-shift nurses, may be a viable option to mitigate fatigue and alertness deterioration among nurses and to maintain patient safety. The multifaceted nature of fatigue, as captured by EMA, is a stronger predictor of medication errors and near misses than device-measured alertness.

ABSTRACT

Burnout is a prevalent issue among healthcare providers affecting up to 54% of physicians and 35% of nurses. Patient Aligned Care Teams (PACT) is a team-based primary care delivery model designed to assure the delivery of high-quality care while improving clinicians' well-being. Limited studies evaluated the relationship between work environment variables and PACT members' burnout and the relationship between PACT members' burnout and patient-centered care. This cross-sectional study is based on the 2018 Veterans Health Administration (VHA) national web-based PACT survey. Burnout was measured using a single-item question that was validated in previous studies. Descriptive statistics and logistic regression were used to analyze the data. Fifty-one percent of primary care providers and 40.12% of nurses reported high burnout. PACT members with a work environment characterized by high-quality team interaction, leadership support, and psychological safety experienced lower levels of burnout. PACT members' burnout explained 6% of the variance in PACT members' ability to deliver patient-centered care. Burnout among PACT members is attributed to multiple personal and occupational variables. This study identified modifiable work environment variables that can be used to inform burnout interventions.

ABSTRACT

Introduction: Anastomotic leakage is a severe complication associated with gastrointestinal surgery. The process of intestinal wound healing is crucial for the successful outcome of digestive tract surgical repair procedures. This research aimed to determine the impact of silver nanoparticles sheet (Acticoat) on the anastomotic healing of the cecum in rabbits. Methods: A total of 48 New Zealand male rabbits in good health were used for cecum transection and anastomosis. The animals were randomized into the control group (C) and the silver nanoparticles group (AgNPs). In the C group, the transected cecum was end-to-end anastomosed with a single layer of simple continuous suture pattern using 3-0 polyglyconate. In contrast, a silver nanoparticle sheet (Acticoat) was covered around the sutured anastomotic line in the AgNPs group. Postoperatively, abdominal ultrasound imaging and the Bristol Rabbit Pain Score (BRPS) were measured on days 7, 15, and 30. Eight rabbits from each group were euthanized at each time point to assess macroscopic findings, bursting pressure tests, tensile strength tests, histopathological examinations, and immunohistochemical analyses. Results: The AgNPs group demonstrated a significant increase in the cecal lumen diameter wall (p ≤ 0.001), burst pressure measurement (p ≤ 0.02), and tensile strength (p ≤ 0.01). Conversely, the AgNPs group had significantly lower BRPS scores (p ≤ 0.01). In addition, histopathological examinations revealed that AgNPs significantly reduced inflammatory cell infiltration (neutrophils and macrophages) and enhanced collagen deposition. Immunohistochemical analyses revealed a significant increase (p ≤ 0.01) of α-SMA and a reduction of CD31 in the anastomotic tissue of the AgNPs group. Discussion: The results of the present study indicate that the utilization of the AgNPs sheet (Acticoat®) effectively enhanced the strength of cecum anastomosis, resulting in a reduction in anastomosis leakages, pain scores, and abdominal adhesions. Additionally, the bursting pressure values in the rabbit model were significantly increased.

ABSTRACT

BACKGROUND: Improved health among older women remains elusive and may be linked to limited knowledge of and interventions targeted to population subgroups. Use of structured community nurse home visit data exploring relationships between client outcomes, phenotypes, and targeted intervention approaches may reveal new understandings of practice effectiveness. MATERIALS AND METHODS: Omaha System data of 2363 women 65 years and older with circulation problems receiving at least 2 community nurse home visits were accessed. Previously identified phenotypes (Poor circulation; Irregular heart rate; and Limited symptoms), 7 intervention approaches (High-Surveillance; High-Teaching/Guidance/Counseling; Balanced-All; Balanced-Surveillance-Teaching/Guidance/Counseling; Low-Teaching/Guidance/Counseling-Balanced Other; Low-Surveillance-Mostly-Teaching/Guidance/Couseling-TreatmentProcedure-CaseManagement; and Mostly-TreatementProcedure+CaseManagement), and client knowledge, behavior, and status outcomes were used. Client-linked intervention approach counts, proportional use per phenotypes, and associations with client outcome scores were descriptively analyzed. Associations between intervention approach proportional use by phenotype and outcome scores were analyzed using parallel coordinate graph methodology for intervention approach effectiveness. RESULTS: Percent use of intervention approach differed significantly by phenotype. The 2 most widely employed intervention approaches were characterized by either a high use of surveillance interventions or a balanced use of all intervention categories (surveillance, teaching/guidance/counseling, treatment-procedure, case-management). Mean outcome discharge and change scores significantly differed by intervention approach. Proportionally deployed intervention approach patterns by phenotype were associated with outcome small effects improvement. DISCUSSIONS AND CONCLUSIONS: The Omaha System taxonomy supported the management and exploration of large multidimensional community nursing data of older women with circulation problems. This study offers a new way to examine intervention effectiveness using phenotype- and targeted intervention approach-informed structured data.

ABSTRACT

OBJECTIVE: The aim of this study was to analyze the perceptions of core team members implementing patient-centered medical home (PCMH) within the Veterans Health Administration regarding delegation of work. BACKGROUND: Significant overlap exists in the performance of work tasks among PCMH team members (primary care providers, RNs, clinical associates, clerks), and scant literature exists on appropriate delegation within PCMH teams. METHODS: This study conducted used a quantitative and qualitative analysis of 4254 respondents to a 2018 survey. RESULTS: Primary care providers rely heavily on team members, and nurses report being relied upon at high levels. Lack of role clarity and a perceived need for a team leader were concerns voiced by participants. CONCLUSIONS: Findings indicated a need for clear guidance on roles and responsibilities within the team. Patient-centered medical home team members need information about the scope of practice of each professional group to allow providers to function at the top of their scope of practice and ensure effective delegation.

ABSTRACT

AIM: This study aimed to investigate the efficiency of topically applied pycnogenol (PYC) in healing the standardized alkaline corneal ulcer in diabetic and normal rats. MATERIALS AND METHODS: The corneal alkali-burn injury (CA-I) model was unilaterally developed in Wistar rats by filter paper saturated with 0.01 M of NaOH and touching the eyes for 45 s. Rats were divided into four groups: Normal control (NC), normal PYC (NPYC), diabetic control (DC), and diabetic PYC (DPYC). Both NPYC and DPYC groups were daily treated with PY eye drops three times, whereas NC and DC ones were treated with ordinary saline for six successive days. RESULTS: The wound healing of corneal epithelial was improved in the NPYC group compared to the NC group. Meanwhile, it was significantly improved (P < 0.05) in the DPYC group than in the DC group. Histological examination revealed that corneal re-epithelialization was more accomplished in the DPYC group than in the DC group. In addition, the inflammatory cells were augmented in the DC group more than those in the DPYC one. CONCLUSION: The findings obtained revealed the efficiency of PYC for enhancing the corneal re-epithelialization and reducing the inflammatory reaction post alkali burn in rats, and thus it could be beneficially valuable as a treatment for the diabetic keratopathy.

ABSTRACT

This study evaluated the diuretic, antioxidant, anti-inflammatory, and immunological effects of a commercial diuretic (CD) (composed of ammonium chloride, potassium citrate, sodium chloride, ascorbic acid, biotin, halfa bar extract, and hexamine) on chickens with induced urolithiasis. A total of 100 one-day-old white Hy-Line chicks were fed a basal diet containing 20% crude protein (CP) and 1% Ca until they reached 48 days of age. Then, the birds were divided into five groups (G1-G5). G1 was fed a basal diet and kept as a negative control, G2 was fed a high protein (HP) diet containing 25% crude protein, G3 was fed high calcium (HC) diet containing 5% Ca, G4 was fed HP diet supplemented with CD, and G5 was fed HC diet supplemented with CD. The CD was supplemented with drinking water (at a dose of 0.5 ml/ liter) for 1 week. The experiment was held for 78 days. Clinical signs, postmortem lesions, and mortality rates were observed. Biochemical analytes, redox status biomarkers, and expression of interleukin-6 (IL-6) and interferon-gamma (IFN-γ) were measured. Tissue samples were taken for histopathological examination. No signs of CD toxicity were observed during the toxicity test prior to the experiment. Compared to all groups, birds in G2 and G3 showed impaired renal function and alterations in biochemical, redox status, lipid peroxidation, post-mortem, and histopathological lesions along with upregulation of IL-6 and IFN-γ in the kidney and spleen. In conclusion, commercial diuretic supplementation for one week improves renal function, redox status, immune and anti-inflammatory responses in chickens with induced urolithiasis.

ABSTRACT

BACKGROUND: Gallinula chloropus (Linnaeus, 1758) is a wild aquatic omnivorous bird characterized by a marked resistance to harsh environmental conditions and a worldwide distribution. In this study, anatomical, morphometrical, histochemical, and immunohistochemical techniques were employed to study the structure of the gastrointestinal tract of Gallinula chloropus. RESULTS: The esophagus appeared tubular with no distinct crop. Both superficial (SPG) and deep (DPG) proventricular glands were present. The DPG filled about two-thirds of the total wall thickness. Histochemically, the mucosubstances revealed mixed alcian blue-PAS positive reactions. They were mainly localized in the acini of the esophageal glands and SPG, gastric surface epithelium, duct system of DPG, and intestinal goblet cells. The highest number of goblet cells per every 1 mm2 of the intestinal mucosa was seen within the ileum and rectum, 2555 ± 468 and 2607 ± 653 respectively. Notably, glucagon immunoreactive (IR) cells were abundant in the mucosa of the small and large intestines and the proventriculus, while somatostatin IR cells were concentrated within the acini of the DPG. IR cells for the mitosis marker phospho-histone H3 (PHH3) were highest within the entire intestinal crypts and mucosa-associated lymphoid tissues (MALT). In contrast, cells IR for the apoptosis marker C.CASP3 were remarkable in epithelial cells at the tips of intestinal villi and in MALT, reflecting the dynamic nature of the latter mentioned structures. CONCLUSIONS: The findings of the present study advance our knowledge of the gross and microscopic anatomy of the gastrointestinal tract in wild birds and could help to enhance the productivity of Aves via improving gut health.

ABSTRACT

Nurses function at the point of care and assume a significant role in intercepting errors. They work in a mentally and physically demanding profession that is comprised of shift-work, subjecting nurses to considerable fatigue. Yet, few studies constructed a comprehensive model that integrates personal and occupational factors to explore their relationship with various types of fatigue (acute, chronic, physical, mental, and total). Here, we examine this type of comprehensive fatigue-model, in a report that represents one aim of a larger, mixed-methods study. The study sample comprised of 1137 registered nurses working in eight hospitals in a Midwestern state. Nurses reported higher levels of acute and total fatigue than chronic and physical fatigue. Staffing and resource adequacy, exercise, and sleep were among the strongest predictors. Since fatigue is a multi-faceted construct, a comprehensive fatigue-management strategy that targets both day and night-shift nurses is the optimal way to manage nurse fatigue.

ABSTRACT

Background: Fatigue is prevalent among hospital nurses and has been linked to medical errors and decreased patient safety. However, little is known regarding the relationship between occupational physical activity, sedentary behavior, and fatigue. Objective: To assess the impact of 12-hour shifts on nurses' fatigue and its relationship to occupational physical activity and sedentary behavior. Design: Prospective-cohort study design Setting(s): Midwestern trauma one academic medical center Participants: A total of 80 registered nurses working 12-hour day and night shifts participated in this study and completed momentary measures of fatigue (texting, aim one). Only 52 participants were included in aim two analyses (included activity monitoring, aim two). Methods: Occupational patterns of momentary fatigue was measured via ecological momentary assessments. Occupational physical activity and sedentary behaviors (e.g., step count, time spent sitting, standing, and walking) were measured for 14 continuous days using the ActivPAL3 micro activity monitor. Mixed models were used to examine the effects of shift type and time within a shift on occupational fatigue. General estimation equations were used to examine the relationship between time spent sitting, standing, and walking on fatigue. Results: Regardless of shift type, nurses exhibited a significant rise in fatigue; however, the rise was greater during night shifts compared to day shifts. Walking was positively associated with fatigue during day shifts, and negatively associated with fatigue during night shifts. Conclusions: The rise in fatigue was greater among nurses working night shifts compared to day shifts, which could place them at greater risk for fatigue-related consequences. The relationship between walking and fatigue was moderated by shift-type. Tweetable abstract: Nursing fatigue rises during 12-hour shifts, but the rise is greater for those working night shifts @DrRobertoBenzo.

ABSTRACT

BACKGROUND: High rates of mental health conditions and poor healthy lifestyle behaviors are reported in nurses, other clinicians, and health science students but have not been compared across different professions. PURPOSE: The purpose of this study was threefold: (1) describe rates of mental health problems and healthy lifestyle behaviors across the Big 10 health professional faculty and students, (2) compare the health and healthy lifestyle behaviors of the Big 10 health sciences faculty and students across health sciences' professions, and (3) identify factors predictive of depression, stress, and anxiety. METHODS: Faculty and students from eight health science colleges at the Big 10 Universities responded to the study survey, which included: demographics, healthy lifestyle behavior questions, and three valid/reliable mental health scales. Descriptive statistics described the findings and multiple linear regression identified factors associated with mental health conditions. RESULTS: Eight-hundred and sixty-nine faculty and 1087 students responded. Approximately 50% of faculty and students reported 7 h of sleep/night, a third achieved 150 min of physical activity/week; 5.5%-9.9% screened positive for depression; and 11.5%-25.5% had anxiety. Age, sleep, and physical activity were associated with lower depression and anxiety. CONCLUSIONS: University leadership must build wellness cultures that make healthy lifestyle behaviors easy to engage in and enhance mental well-being.

ABSTRACT

This study was carried out to evaluate the effects of induced urolithiasis by high dietary calcium (Ca) or protein levels on biochemical analyte levels, redox status, selected inflammatory cytokines and histopathology in chickens. A total of 90 one-day-old white Hy-Line chicks were fed basal control diets containing 20% crude protein (CP) and 1% Ca until they reached 44 days of age. After that, the birds were divided into three groups (30 birds per group). All management factors (light, temperature, ventilation, stock density and diet) were identical among the three groups throughout the study except for the dietary Ca and protein percentages. Group I was fed a control diet containing 20% CP and 1% Ca, group II was fed a high-Ca diet containing 5% Ca, and group III was fed a high-protein diet containing 25% CP. Our findings clearly demonstrated that dietary imbalance (caused by high-Ca or high-CP levels) per se in chickens was physiologically harmful, as it was accompanied by post-mortem lesions; biochemical, redox status and histopathological alterations; and upregulation of inflammatory cytokines (interleukin (IL)-1ß and IL-6). In particular, the birds fed the high-Ca diet clearly exhibited the most obvious alterations in most of the endpoints. In conclusion, this study constitutes the first extensive investigation of the effects of high-Ca or high-protein diets induced urolithiasis on growth performance, redox status, inflammatory cytokine levels and pathological characterization in chickens.

ABSTRACT

Medication near-misses occur at higher rates than medication errors and are usually underreported. Reporting a medication near-miss is crucial, as it highlights areas of human and system failures. Identifying these incidents is particularly important in nursing home (NH) settings to help managers plan and initiate proactive measures to contain the errors. However, scarce evidence exists about predictors of nurses' willingness to report near-misses. Therefore, the purpose of this study was to test a proposed model for NH nurses' willingness to report medication near-misses. Data for this cross-sectional study were collected using a random sample of RNs working in NHs across one Midwestern state. The proposed model predicted a 19% variance in nurses' willingness to report medication near-misses, with the strongest predicators being non-punitive responses to errors (ß = 0.33, p < 0.001). According to the study results, system and social factors are needed to improve nurses' voluntary reporting of medication near-misses. [Journal of Gerontological Nursing, 46(4), 21-30.].

ABSTRACT

BACKGROUND: Little is known about how team processes impact providers' abilities to prepare patients for a safe hospital discharge. Teamwork Shared Mental Models (teamwork-SMMs) are the teams' organised understanding of individual member's roles, interactions and behaviours needed to perform a task like hospital discharge. Teamwork-SMMs are linked to team effectiveness in other fields, but have not been readily investigated in healthcare. This study examines teamwork-SMMs to understand how interprofessional teams coordinate care when discharging patients. METHODS: This mixed methods study examined teamwork-SMMs of inpatient interprofessional discharge teams at a single hospital. For each discharge event, we collected data from the patient and their discharge team (nurse, physician and coordinator) using interviews and questionnaires. We quantitatively determined the discharge teams' teamwork-SMM components of quality and convergence using the Shared Mental Model Scale, and then explored their relationships to patient-reported preparation for posthospital care. We used qualitative thematic analysis of narrative cases to examine the contextual differences of discharge teams with higher versus lower teamwork-SMMs. RESULTS: The sample included a total of 106 structured patient interviews, 192 provider day-of-discharge questionnaires and 430 observation hours to examine 64 discharge events. We found that inpatient teams with better teamwork-SMMs (ie, higher perceptions of teamwork quality or greater convergence) were more effective at preparing patients for post-hospital care. Additionally, teams with high and low teamwork-SMMs had different experiences with team cohesion, communication openness and alignment on the patient situation. CONCLUSIONS: Examining the quality and agreement of teamwork-SMMs among teams provides a better understanding of how teams coordinate care and may facilitate the development of specific team-based interventions to improve patient care at hospital discharge.

ABSTRACT

Mesenchymal stem cells (MSCs) are undifferentiated cells that have the ability of self-renewal and trans-differentiation into other cell types. They hold out hope for finding a cure for many diseases. Nevertheless, there are still some obstacles that limit their clinical transplantation. One of these obstacles are the xenogeneic substances added in either proliferation or differentiation media with subsequent immunogenic and infectious transmission problems. In this study, we aimed to replace fetal bovine serum (FBS), the main nutrient source for MSC proliferation with xeno-free blood derivatives. We tested the effect of human activated pure platelet-rich plasma (P-PRP) and advanced platelet-rich fibrin (A-PRF) on the proliferation of human adipose derived-MSCs (AD-MSCs) at different concentrations. For the induction of MSC neural differentiation, we used human cerebrospinal fluid (CSF) at different concentrations in combination with P-PRP to effect xeno-free/species-specific neuronal/glial differentiation and we found that media with 10% CSF and 10% PRP promoted glial differentiation, while media with only 10% PRP induced a neuron-like phenotype.

ABSTRACT

One of the major impacts of spinal cord injury (SCI) is the cerebellar neurological malfunction and deformation of its sub-layers. This could be due to the enormous innervation of the spinocerebellar tract from the posterior gray horn in the spinal cord to the ipsilateral cerebellum. Although the neuroprotective role of estradiol in spinal cord (SC) injuries, as well as its ability to delay secondary cell death changes, is well-known, its effect on cerebellar layers is not fully investigated. In this study, a SCI model was achieved by injection of Kainic acid into SC of adult Male Wistar rats in order to assess the effects of SCI on the cerebellum. The animals were classified into SCI group (animals with SCI), estradiol-treated group (animals with SCI and received estradiol), control groups, and sham control group. The microscopical examination 24 h after induction of SCI revealed that KA induced the most characteristics of neurodegeneration including astrocytic propagation and microglial activation. The estradiol was injected intraperitoneally 20 min after induction of SCI, and the samples were collected at 1, 3, 7, 14, and 30 days. Histologically, the estradiol reduced the inflammatory response, enhanced the recovery of molecular, granular, and Purkinje cell layers, and therefore aided in the restoration of layer organization. These findings were also confirmed by immunohistochemical staining and gene expression profiling.

ABSTRACT

Medication errors are common in health care settings. Safety motivation, such as willingness to report error, is needed to contain medication errors. Limited evidence exists about measures to enforce nurses' safety motivation. The purpose of this study was to test a proposed model explaining the mechanism by which organizational and social factors influence nurses' safety motivation. Survey for this cross-sectional study was mailed to a random sample of 500 acute care nurses. Data collection started in January 2014 and lasted 6 months. Path analysis results showed a good fitting final model with 15% of explained variance on nurses' safety motivation. Safety climate dimensions of error feedback (ß = .38, p ⩽ .00) and nonpunitive response to errors (ß = .22, p = .01) significantly predicted the outcome. There is a need for both organizational and social factors to motivate nurses to report errors. Leadership practices emphasizing safety as a priority is needed to enhance nurses' safety motivation.
