Predictive Modeling for One-Year Lower Extremity Endovascular Revascularization Failure in Black Persons.

INTRODUCTION: Black persons bear a disproportionate burden of peripheral artery disease (PAD) and experience higher rates of endovascular revascularization failure (ERF) when compared with non-Hispanic White persons. We aimed to identify predictors of ERF in Black persons using predictive modeling. METHODS: This retrospective study included all persons identifying as Black who underwent an initial endovascular revascularization procedure for PAD between 2011 and 2018 at a midwestern tertiary care center. Three predictive models were developed using (1) logistic regression, (2) penalized logistic regression (least absolute shrinkage and selection operator [LASSO]), and (3) random forest (RF). Predictive performance was evaluated under repeated cross-validation. RESULTS: Of the 163 individuals included in the study, 113 (63.1%) experienced ERF at 1 y. Those with ERF had significant differences in symptom status (P < 0.001), lesion location (P < 0.001), diabetes status (P = 0.037), and annual procedural volume of the attending surgeon (P < 0.001). Logistic regression and LASSO models identified tissue loss, smoking, femoro-popliteal lesion location, and diabetes control as risk factors for ERF. The RF model identified annual procedural volume, age, PAD symptoms, number of comorbidities, and lesion location as most predictive variables. LASSO and RF models were more sensitive than logistic regression but less specific, although all three methods had an overall accuracy of ≥75%. CONCLUSIONS: Black persons undergoing endovascular revascularization for PAD are at high risk of ERF, necessitating need for targeted intervention. Predictive models may be clinically useful for identifying high-risk patients, although individual predictors of ERF varied by model. Further exploration into these models may improve limb salvage for this population.

Social Determinants of Health Factors and Loss-To-Follow-Up in the Field of Vascular Surgery.

BACKGROUND: It is estimated that 22-57% of vascular patients are lost to follow-up (LTF) which is of concern as the Society of Vascular Surgery recommends annual patient follow-up. The purpose of this report was to identify social determinants of health factors (SDoH) and their relationship to LTF in vascular patients. METHODS: The methods employed were a systematic literature review of 29 empirical articles and a retrospective quality improvement report with 27 endovascular aortic repair (EVAR) and thoracic endovascular aortic repair (TEVAR) patients at the University of Chicago. RESULTS: The systematic literature review resulted in 2,931 articles which were reduced to 29 articles meeting the inclusion criteria. Demographic variables were more frequently cited than SDoH factors, but the most common were smoking, transportation, and socioeconomic status/insurance. Additionally, 176 EVAR and TEVAR patients were called resulting in 27 patients who completed a SDoH questionnaire. Twenty-six percent indicated they had missed at least 1 appointment with the top reasons being work or family responsibilities. Due to limited patient size no statistical analyses were performed, but frequencies of responses to SDoH questions were reported to augment the existing limited literature and guide future research into variables such as one's ability to pay for basics like food or mortgage. CONCLUSIONS: SDoH factors are important yet understudied aspects of endovascular repairs that require more research to understand their impact on vascular surgery follow-up rates and outcomes. Additional research is needed as lack of consideration of such factors may impact the generalizability of existing research and such knowledge may help in informing clinician treatment plans.

Inpatient pediatric nursing staff experiences treating psychiatric patients: A mixed methods study.

PROBLEM: A gap in the literature exists attempting to understand the impact that the influx of pediatric psychiatric patients has had on inpatient general medicine pediatric nursing staff. METHODS: A mixed-method research study was conducted among full- and part-time pediatric nurses and nursing assistants working on general pediatric units. Quantitative data was collected via an anonymous survey using the Professional Quality of Life Scale version 5 and Support Appraisal for Work Stressors scale. Surveys were followed by semistructured interviews. FINDINGS: Of the 158 staff eligible, 47 (29.7%) participated in the quantitative portion. [Correction added on 29 September 2023, after the first online publication: In the preceding sentence, the participation rate was revised from 23.5% to 29.7% in this version.] Significant differences were found between roles, with nurses experiencing lower levels of compassion satisfaction and higher levels of burnout. Role differences were seen in supervisor support and nonwork support, with nurses reporting less support from both. Supervisor support showed a significant correlational relationship with compassion satisfaction and burnout. Nonwork support showed similar correlations with compassion satisfaction and burnout. Themes that emerged from the interviews were Barriers to Care, Emotional Impact, and "Help Me Help You." CONCLUSION: Nurses may be at greater risk for compassion fatigue due to perceived inadequate support from leadership, unclear role expectations, and lack of resources.

Hypotensive Events in Pediatric Patients Receiving Dexmedetomidine for MRI.

PURPOSE: Dexmedetomidine, the preferred pediatric sedating agent for magnetic resonance imaging (MRI), has the side effect of hypotension. Newer recommendations for reporting adverse events in pediatric procedural sedation include using a two-pronged definition. Our aim was to describe the incidence of hypotension in patients undergoing sedated MRI and to identify demographic and clinical factors associated with hypotension, applying a two-pronged definition, where a numerical threshold/clinical criterion must be met as well as at least one clinical intervention performed. DESIGN: An observational cohort study. METHODS: Medical record data were extracted for outpatients less than 18 years of age sedated primarily with dexmedetomidine for MRI in a single center for over a seven-year period. Patients who received propofol as an adjunct were also included. Hypotension was defined using a two-pronged approach, as a 20% reduction in systolic blood pressure from baseline lasting ≥10 minutes, coupled with a fluid bolus. Analysis included descriptive statistics, t tests and logistic regression using discrete-time survival analysis. FINDINGS: Of the 1,590 patient encounters, 90 (5.7%) experienced hypotension. Males were significantly more likely to have hypotension. Patients with hypotension had overall longer appointment times, including longer sedation times and recovery time. Greater blood pressure (BP) variability in the preceding 20 minutes also increased the risk of hypotension. CONCLUSIONS: Our lower incidence of hypotension is likely related to the two-pronged intervention-based definition used, as it likely more accurately reflects clinically meaningful hypotension. To our knowledge, this is the first study using this approach with this population. Research further examining the relationship between prolonged sedation, blood pressure variability, gender, hypotension, and recovery time is needed. Understanding these relationships will help interdisciplinary teams, including nurses in pediatric procedural areas, to reduce the incidence of hypotension, potentially maximize patient safety, and optimize throughput.

Using a Cascading Approach to Improve Multisite Study Procedures.

BACKGROUND: Multisite studies offer larger, more diverse samples to successfully capture populations and clinical practices of interest at the point of care. However, investigators face challenges with site recruitment and sampling, differences in clinical practices across sites, and data integrity. Addressing these issues a priori can improve the rigor and reproducibility of the research. OBJECTIVE: This article aims to describe a cascading approach to multisite research. An exemplar is provided of a study using this approach, which aimed to evaluate the prevalence of pain and the pain management practices provided to critically ill children in pediatric intensive care units in the United States. METHODS: The cascading approach includes two or more pilot study procedures with a progressively increasing number of sites prior to a full-scale study. Following each pilot, study procedures are evaluated; feedback was obtained from site personnel and content experts; procedures were revised accordingly; approvals were obtained; sites were trained; and the revised procedures are repeated with a larger, more diverse number of sites. RESULTS: In the exemplar provided, improvements in the efficiency and integrity of data collection were noted for the full-scale study following the pilots. All sites that completed the agreements and approvals for study participation were retained for the duration of the two pilots and full-scale study. DISCUSSION: Borrowing from principles of process improvement, the cascading approach allows knowledge to be gained regarding site differences and informs the revision of study procedures while potentially maximizing efficiency and data integrity, minimizing site burden, and maintaining site engagement for multisite studies.

Transitioning to Independent Nursing Practice during COVID-19: A Mixed Methods Study.

The COVID-19 pandemic presented challenges to onboard and support new graduate nurses (NGNs). This study sought to explore the perceptions of nurses entering clinical practice during the COVID-19 pandemic. Using mixed methods, we investigated the experiences of NGNs entering the field during the pandemic and how a nurse residency program (NRP) adapted to meet their needs. Newly graduated nurses entering practice in November 2019 described their transition through nurse experience surveys and focus group discussions. Results from the quantitative data reported on compassion satisfaction, burnout, and exposure to secondary traumatic stress. The qualitative data mirrored these findings with the discovery of the following five themes: transitioning through an NRP, impact to nursing care, value of coworkers, coping, and professional growth. These findings illustrate the need to better support future practice transitions in times of disruption and change.

Quantifying Compassion Fatigue in Ancillary and Clinical Staff in an Adult Emergency Department.

INTRODUCTION: Emergency department (ED) staff are at a high risk for compassion fatigue (CF) due to a work environment that combines high patient acuity, violence, and other workplace stressors. This multifaceted syndrome has wide-ranging impacts which, if left untreated, can lead to adverse mental health conditions including depression, anxiety, and substance use disorders. However, the majority of studies examining CF look solely at clinicians; as a result, there is little information on the impact of CF across other roles involved in supporting patient care. We conducted this study to establish the prevalence of CF across both clinical and non-clinical roles in the adult ED setting. METHODS: For this single institution, cross-sectional study, all full- and part-time ED staff members who worked at least 50% of their shifts in the ED or within the adult trauma service line were eligible to participate. Using the Professional Quality of Life Scale, which measures CF via compassion satisfaction (CS), burnout (BO), and secondary traumatic stress (STS), we assessed for group differences between roles using non-parametric one-way ANOVA. RESULTS: A total of 152 participants (response rate = 38.0%) completed the survey. This included attending physicians (n = 15, 9.7%), resident/fellow physicians (n = 23, 15.1%), staff nurses (n = 54, 35.5%), emergency technicians (n = 21, 13.8%), supportive clinical staff (n = 28, 18.4%), and supportive ancillary staff (n = 11, 7.2%). Across all roles, the majority of respondents had average levels of BO (median = 25.0, interquartile range [IQR] 20.0-29.0) and STS (median = 23.0, IQR 18.0-27.0) coupled with high levels of CS (median = 38.0, IQR 33.0-43.0). There was a difference in CS by role (P = .01), with nurses reporting lower CS than attending physicians. Secondary traumatic stress also differed by role (P = .01), with attending physicians reporting lower STS than both emergency technicians and nurses. Group differences were not seen in BO. CONCLUSIONS: Rates of compassion fatigue subcomponents were similar across all ED team members, including non-clinical staff. Programs to identify and mitigate CF should be implemented and extended to all roles within the ED.

Nurse-Driven Assessment, Prevention, and Management of Delirium on an Acute Inpatient Neurology Unit.

BACKGROUND: Delirium commonly affects hospitalized patients and is associated with increased hospital length of stay, discharge to skilled care, cost, morbidity, and mortality. LOCAL PROBLEM: At our organization, there was no formal delirium assessment performed by the nursing staff outside of the intensive care unit. METHODS: Assessment of nurses' knowledge about delirium, a nurse-driven delirium screening protocol, and patient education were implemented on an adult inpatient neurology unit. Knowledge change, protocol implementation, and patient-level outcomes were assessed. INTERVENTIONS: Staff nurse delirium education and a nurse-driven delirium screening protocol were implemented. RESULTS: No change in nursing knowledge occurred pre/postintervention. Falls, falls with injury, and restraint and sitter usage decreased. Changes in length of stay varied over the intervention period. The trend to discharge to home increased, while the trend to discharge to skilled nursing care decreased. CONCLUSIONS: Formal delirium screening protocols may add organizational value by positively impacting patient outcomes.

Palliative Care Utilization Following Out-of-Hospital Cardiac Arrest in Pediatrics.

OBJECTIVES: Pediatric out-of-hospital cardiac arrest (OHCA) is associated with significant morbidity and mortality. Pediatric palliative care (PPC) services could provide an integral component of the comprehensive care necessary for these patients and their families. The main objectives of this study are to examine the utilization of PPC following OHCA and compare the differences in characteristics between children who received PPC with those who did not. DESIGN: Retrospective cohort study. SETTING: An urban, tertiary PICU. PATIENTS: Children less than 21 years old admitted from October 2009 to October 2019 with an admitting diagnosis of OHCA and minimum PICU length of stay (LOS) of 48 hours. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Of the 283 patient charts reviewed, 118 patient encounters met inclusion criteria. Of those, 34 patients (28.8%) received a PPC consultation during hospitalization. Patients who received PPC had a longer PICU LOS (14.5 vs 4.0 d), a greater number of ventilator days (12.5 vs 4.0 d), and a larger proportion of do-not-resuscitate (DNR) statuses (41% vs 19%). When comparing the disposition of survivors, a greater proportion was discharged to rehab or nursing facilities (47% vs 28%), with no difference in mortality rates (53% vs 50%). In the multivariate logistic regression model, older age, longer LOS, and code status (DNR) were all associated with higher likelihood of PPC utilization. Data were analyzed using descriptive, Mann-Whitney U, and Fisher exact statistics. CONCLUSIONS: Our study demonstrates PPC services following OHCA are underutilized given the high degree of morbidity and mortality. The impact of automatic PPC consultation in all OHCA patients who survive beyond 48 hours should be explored further. Future studies are warranted to understand the benefits and barriers of PPC integration into standard postarrest care for patients and families.

Predicting Who Receives Nonpharmacologic Pain Interventions in the Pediatric Intensive Care Unit.

AIMS: The majority of patients in the pediatric intensive care unit (PICU) experience pain daily, while nonpharmacologic interventions are indicated for pain management in children, there is limited information on which nonpharmacologic interventions are provided in the PICU and which patients receive those interventions. The aim of this descriptive correlational secondary data analysis was to determine what nonpharmacologic interventions were recorded in the electronic health record of PICU patients and patterns in use by patient demographics. SETTING/SUBJECTS: All patients hospitalized in 15 participating PICUs are located within 12 unique children's hospitals across the United States were eligible for participation. METHODS: Nonpharmacologic interventions used in the PICU were identified and differences between patients who did and did not receive those interventions were examined using Fisher's exact test. A generalized linear mixed effects model was constructed to determine patient characteristics that predict nonpharmacologic pain intervention application. RESULTS: Of 220 enrolled patients, 97 (44%) had nonpharmacologic pain interventions recorded in their electronic health record. The most frequently recorded interventions included repositioning (65%), decreasing environmental stimuli (55%), caregiver presence (37%), distraction (23%), and music therapy (20%). Children who had moderate to severe pain were most likely to receive nonpharmacologic pain interventions. CONCLUSIONS: Nonpharmacologic pain management is applied inconsistently across PICUs and may be underdocumented or underutilized. Additional research is needed to determine when nurses use nonpharmacologic pain interventions, their rationale for applying these interventions across differing groups, and the effectiveness of these interventions in managing pain in critically ill children.

Racial and Ethnic Differences in Inpatient Palliative Care for Pediatric Stem Cell Transplant Patients.

OBJECTIVES: Racial/ethnic disparities in utilizing inpatient palliative care services are well documented in the adult literature. However, the impact of racial/ethnic disparities in the context of pediatric palliative care is less well understood even in high-acuity patient populations such as stem cell transplant patients. We investigated racial/ethnic differences in the utilization of inpatient palliative care consultations (IPCCs) for pediatric stem cell transplant patients. STUDY DESIGN: A retrospective cohort study was conducted using the Pediatric Health Information System database. A generalized linear mixed effects model was developed to assess demographic and clinical characteristics associated with the likelihood of receiving IPCC. SETTING: Thirty-eight tertiary pediatric hospitals in the United States. PATIENTS: Pediatric patients undergoing stem cell transplantation for any indication from January 2017 to December 2019. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Of the 1,193 inpatient encounters studied, 12% (n = 143) included a palliative care consult. IPCC rates varied across hospitals with a median rate of 5.97% (interquartile range, 0.00-20.71). In multivariable analyses, Hispanic/Latinx patients were 59% less likely to receive IPCC compared with non-Hispanic White patients (odds ratio [OR], 0.41; 95% CI, 0.21-0.78). This difference persisted after adjusting for all other sociodemographic and clinical factors. In terms of the other clinical characteristics, having a malignant condition and mechanical ventilation were associated with significantly increased odds of receiving IPCC for the entire cohort (OR Malignancy: 1.93; 95% CI: 1.07-3.51; OR Mechanical Ventilation: 2.37; 95% CI: 1.36-4.13). The remainder of the variables were not found to be significantly associated with IPCC. CONCLUSIONS: Racial and ethnic differences exist in the likelihood of receiving palliative care consultations among hospitalized pediatric stem cell transplant recipients. Evaluating the impact of systemic racism and social determinants on palliative care medicine as well as standardizing early integration of IPCC may potentially mitigate disparities in this population.

Novel Trauma Composite Score is superior to Injury Severity Score in predicting mortality across all ages.

BACKGROUND: Injury Severity Score (ISS) is a widely used metric for trauma research and center verification; however, it does not account for age-related physiologic parameters. We hypothesized that a novel age-based injury severity metric would better predict mortality. METHODS: Adult patients (≥18 years) sustaining blunt trauma (BT) or penetrating trauma (PT) were abstracted from the 2010 to 2016 National Trauma Data Bank. Admission vitals, Glasgow Coma Scale, ISS, mechanism, and outcomes were analyzed. Patients with incomplete/non-physiologic vital signs were excluded. For each age: (1) a cut point analysis was used to determine the ISS with the highest specificity and sensitivity for predicting mortality and (2) a linear discriminant analysis was performed using ISS, ISS greater than 16, Trauma and Injury Severity Score, and Revised Trauma Scale to compare each scoring system's mortality prediction. A novel injury severity metric, the trauma component score (TCS), was developed for each age using significant (p < 0.05) variables selected from Abbreviated Injury Scale scores, Glasgow Coma Scale, vital signs, and gender. Receiver operator curves were developed and the areas under the curve were compared between the TCS and other systems. RESULTS: There 777,794 patients studied (BT, 91.1%; PT, 8.9%). Blunt trauma patients were older (53.6 ± 21.3 years vs. 34.4 ± 13.8 years), had higher ISS scores (11.1 ± 8.5 vs. 8.5 ± 8.9), and lower mortality (2.9% vs. 3.4%) than PT patients (p < 0.05). When assessing the entire PT and BT cohort the optimal ISS cut point was 16. The optimal ISS was between 20 and 25 for BT younger than 70 years. For those older than 70 years, the optimal BT ISS steadily declined as age increased PT's cut point was 16 or less for all ages assessed. When the injury metrics were compared by area under the curve, our novel TCS more accurately predicted mortality across all ages in both BT and PT (p < 0.001). CONCLUSION: Injury Severity Score is a poor mortality predictor in older patients and those sustaining penetrating trauma. The age-based TCS is a superior metric for mortality prediction across all ages. LEVEL OF EVIDENCE: Clinical outcomes, Level IV.

Quality of Transition From Hospital to Home: The Influence of Nurse- and Patient-Reported Readiness.

Identifying those at risk of poor outcomes after hospital discharge is a central focus of health care systems. Our purpose was to better understand whether and how patient- and nurse-assessed readiness for discharge (Pt- and RN-RHDS) is related to patient experiences after discharge. We conducted a prospective survey of 70 Veterans and their assigned nurses on the day of, and again with Veterans 2 weeks after, hospital discharge. The predictive model for post-discharge coping difficulty included educational level ( p = .05) and an interaction between Pt-RHDS ratings and Pt-RN RHDS discordance ( p = .01). The predictive model for patient-reported quality of hospital to home transition experience included Pt-RN RHDS discordance and an interaction between Pt-RHDS and the number of people living with the patient ( p = .05). Our findings demonstrate that agreement between Pt- and RN-RHDS may be an important measure in work aiming to improve patient outcomes post-hospitalization.

Testing a Resilience Training Program in Police Recruits: A Pilot Study.

BACKGROUND: Stress from multiple sources is inherent in law enforcement. However, it is possible to modify responses to stress with resilience training that includes teaching techniques to modify emotional and physical responses to stress, interface with mental health professionals, and practice sessions to improve self-regulation of responses to stress including coherence, a measure of heart rate variability. A gap exists in the research, however, regarding evaluation of the duration of effects after the initial resilience training. METHOD: Subjects included ( N = 34) recruits enrolled in summer 2015 at the Milwaukee Police Academy. An experimental design was used to compare recruits who received resilience training to recruits in the control group. RESULTS: No statistically significant differences between the groups were found for self-reported measures of stress and resilience. For the treatment group ( n = 17), change in coherence was significant ( p < .001) and improvement in the Personal Organizational Quality Assessment Emotional Buoyancy subscale correlated significantly with the number of practice sessions ( r = .63, p = .01) and marginally with change in coherence ( r = .47, p = .07). CONCLUSION: Results confirm several significant effects of resilience training with recruits.

Pain sensitivity profiles in patients with advanced knee osteoarthritis.

The development of patient profiles to subgroup individuals on a variety of variables has gained attention as a potential means to better inform clinical decision making. Patterns of pain sensitivity response specific to quantitative sensory testing (QST) modality have been demonstrated in healthy subjects. It has not been determined whether these patterns persist in a knee osteoarthritis population. In a sample of 218 participants, 19 QST measures along with pain, psychological factors, self-reported function, and quality of life were assessed before total knee arthroplasty. Component analysis was used to identify commonalities across the 19 QST assessments to produce standardized pain sensitivity factors. Cluster analysis then grouped individuals who exhibited similar patterns of standardized pain sensitivity component scores. The QST resulted in 4 pain sensitivity components: heat, punctate, temporal summation, and pressure. Cluster analysis resulted in 5 pain sensitivity profiles: a "low pressure pain" group, an "average pain" group, and 3 "high pain" sensitivity groups who were sensitive to different modalities (punctate, heat, and temporal summation). Pain and function differed between pain sensitivity profiles, along with sex distribution; however, no differences in osteoarthritis grade, medication use, or psychological traits were found. Residualizing QST data by age and sex resulted in similar components and pain sensitivity profiles. Furthermore, these profiles are surprisingly similar to those reported in healthy populations, which suggests that individual differences in pain sensitivity are a robust finding even in an older population with significant disease.

Readiness for Hospital Discharge, Health Literacy, and Social Living Status.

Patient characteristics and lack of preparedness are associated with poor outcomes after hospital discharge. Our purpose was to explore the association between patient characteristics and patient- and nurse-completed Readiness for Hospital Discharge Scale (RHDS). We conducted a prospective study of 70 Veterans being discharged from medical and surgical units. Differences in RHDS knowledge subscale scores were found among literacy levels, with lower perceived knowledge reported for those with marginal or inadequate literacy (p = .03). Differences in RHDS expected support subscale scores were also found, with those who were unmarried and/or living alone (p < .001) anticipating less support upon discharge. No other differences were found. Similar differences were found for the RHDS completed by nurses. These findings suggest that the RHDS appears responsive to differences in health literacy and social environment, adding to evidence of its utility as a tool to identify, and plan interventions for, those at risk for readmission.
