Impact Of Fall Education To Oncology Staff On Oncology Patient Fall Rates, Danni Sloane Apr 2024

Impact Of Fall Education To Oncology Staff On Oncology Patient Fall Rates, Danni Sloane

Articles, Abstracts, and Reports

Significance & Background

Falls and fall-related injuries impact patients' health outcomes and are the most commonly reported adverse event in hospitals. Patient falls also affect reimbursement rates and can increase length of stay by about 6.3 days and increase undue patient harm. An increase of patients falls on the medical and surgical oncology acute care units have caused undue physical harm, increased moral distress, mental fatigue, and burnout in nurses; as well as placing financial burdens on the healthcare system. Implementing fall education and interventions aligns with national patient safety goals, is a top-priority project, is in alignment with the …

Implementing A Mentorship Program On A Medical/Oncology Unit, Nicole Frye, Stephanie Perreiah, Jenna Vansanford Oct 2023

Implementing A Mentorship Program On A Medical/Oncology Unit, Nicole Frye, Stephanie Perreiah, Jenna Vansanford

Central Division Nurse Clinical Inquiry Conference

Abstract:

Title: Implementing a Mentorship Program on a Medical/Oncology Unit Background: New-to-specialty acute care nurses are generally assigned a preceptor to demonstrate complex competencies within 90 days of hire. However, providing inpatient nursing care presents psychosocial stressors not well-addressed by preceptors which can contribute to burnout and turnover. Participating in a mentorship program addressing psychosocial nursing stressors following competency-focused preceptorship may reduce burnout and turnover. A medical-oncology unit of a 200-bed urban hospital lacked a mentorship program and Unit-Based Council (UBC) members worked to implement and evaluate this resource. Purpose: To evaluate barriers and facilitators of participation in a new …


Oncology Infusion Nurses' Personal Protective Equipment Use While Handling Hazardous Drugs, Deborah Yoon Apr 2023

Oncology Infusion Nurses' Personal Protective Equipment Use While Handling Hazardous Drugs, Deborah Yoon

Articles, Abstracts, and Reports

Infusion Nurses’ Personal Protective Equipment Use While Handling Chemotherapy Drugs Purpose: To describe perceived barriers, perceived risks, interpersonal influence (modeling and norms), perceived conflict of interest, and organizational influences and select demographics related to Personal Protective Equipment (PPE) use for out-patient, oncology infusion nurses. Background: The proper use of PPE should be common practice among nurses who administer chemotherapy. However, despite training and education, many studies have demonstrated that infusion nurses’ PPE adherence is as low as 50%. Improper PPE use can increase exposure to chemotherapy and has potential adverse health effects including fertility issues and risks of cancer. Few …

Interprofessional Collaboration Optimizes Oncology Navigation Efficiency And Value​, Lauri Ledbeter, Whitney Daws, Rebekah Hart, Lindsay Shimizu Feb 2023

Interprofessional Collaboration Optimizes Oncology Navigation Efficiency And Value​, Lauri Ledbeter, Whitney Daws, Rebekah Hart, Lindsay Shimizu

Providence Nursing Research Conference 2023 – Present

Background: Oncology navigation programs have evolved to include services for addressing cancer care barriers, focusing on care coordination, patient experience, and care value, and may include nurses, social workers, and non-licensed trained workers as care navigators. The 2023 Enhancing Oncology Payment Model (EOPM) requires navigation services and emphasizes improving care value and outcomes. Effective healthcare navigation and collaboration can improve value by reducing care duplication, missed appointments, and emergency admissions; identifying and addressing health-related social needs; addressing health inequities; and improving time-to-treatment initiation and patient retention. The Institute of Medicine also advocates for healthcare professionals to work interprofessionally, implement quality …

Psychometric Characteristics And Validity Of The Promis Cancer Function Brief 3d Profile, Sean R. Smith, Mary Vargo, David S Zucker, Samman Shahpar, Lynn Gerber, Maryanne Henderson, Gina Jay, Minji Lee, Andrea Cheville

All Podium Presentations

Purpose: To develop an item response theory (IRT)-calibrated patient-reported outcome measure (PRO) that assesses cancer patient physical function, fatigue and social participation.

Problem Statement: The subspecialty of cancer rehabilitation medicine (CRM) has to date lacked a psychometrically validated patient-reported outcome measure that assesses patients’ physical function, fatigue, and social participation. A significant proportion of the 16.9 million US cancer survivors will experience, or have already experienced, impairments that compromise function, a predictable consequence of their disease and treatment. While each disease site and line of treatment may be associated with unique impairments, there are some that cut across several cancers …

Development Of A Smartphrase In The Electronic Health Record To Promote Chemotherapy And Immunotherapy Safety, Mary Jo Sarver, Monica Mcmanus, Amy Allen, Bethany Johnson, Dennielle Padgett, Elizabeth Ser

2021 Providence Nurse Research Conference

Background: Chemotherapy-immunotherapies are high risk medications that can include multi-drug and multi-day regimens with narrow therapeutic indexes and high risk for toxicities. Susceptibility for errors exists if adherence to protocol is inconsistent or if pertinent patient specific information is omitted. Prior to the creation of the "SmartPhrase" in the Electronic HealthRecord (EHR) pre-administration safety checks were on paper, not included in the EHR, not standardized among clinicians, and not completed every time. Chart audits revealed a need for consistent, centralized documentation to enhance patient safety while minimizing professional liability. A trans-disciplinary team created a "SmartPhrase" template for streamlining relevant …

Despite the success of checkpoint blockade in some cancer patients, there is an unmet need to improve outcomes. Targeting alternative pathways, such as costimulatory molecules (e.g. OX40, GITR, and 4-1BB), can enhance T cell immunity in tumor-bearing hosts. Here we describe the results from a phase Ib clinical trial (NCT02274155) in which 17 patients with locally advanced head and neck squamous cell carcinoma (HNSCC) received a murine anti-human OX40 agonist antibody (MEDI6469) prior to definitive surgical resection. The primary endpoint was to determine safety and feasibility of the anti-OX40 neoadjuvant treatment. The secondary objective was to assess the effect of …

Articles, Abstracts, and Reports

Genetic mutations lead to the production of mutated proteins from which peptides are presented to T cells as cancer neoantigens. Evidence suggests that T cells that target neoantigens are the main mediators of effective cancer immunotherapies. Although algorithms have been used to predict neoantigens, only a minority are immunogenic. The factors that influence neoantigen immunogenicity are not completely understood. Here, we classified human neoantigen/neopeptide data into three categories based on their TCR-pMHC binding events. We observed a conservative mutant orientation of the anchor residue from immunogenic neoantigens which we termed the "NP" rule. By integrating this rule with an existing …

Prognostic Gene Expression Signatures Of Breast Cancer Are Lacking A Sensible Biological Meaning., Kalifa Manjang, Shailesh Tripathi, Olli Yli-Harja, Matthias Dehmer, Galina Glazko, Frank Emmert-Streib

Articles, Abstracts, and Reports

The identification of prognostic biomarkers for predicting cancer progression is an important problem for two reasons. First, such biomarkers find practical application in a clinical context for the treatment of patients. Second, interrogation of the biomarkers themselves is assumed to lead to novel insights of disease mechanisms and the underlying molecular processes that cause the pathological behavior. For breast cancer, many signatures based on gene expression values have been reported to be associated with overall survival. Consequently, such signatures have been used for suggesting biological explanations of breast cancer and drug mechanisms. In this paper, we demonstrate for a large …

Integrated Genetic And Metabolic Landscapes Predict Vulnerabilities Of Temozolomide Resistant Glioblastoma Cells., Selva Rupa Christinal Immanuel, Avinash D Ghanate, Dharmeshkumar S Parmar, Ritu Yadav, Riya Uthup, Venkateswarlu Panchagnula, Anu Raghunathan

Articles, Abstracts, and Reports

Metabolic reprogramming and its molecular underpinnings are critical to unravel the duality of cancer cell function and chemo-resistance. Here, we use a constraints-based integrated approach to delineate the interplay between metabolism and epigenetics, hardwired in the genome, to shape temozolomide (TMZ) resistance. Differential metabolism was identified in response to TMZ at varying concentrations in both the resistant neurospheroidal (NSP) and the susceptible (U87MG) glioblastoma cell-lines. The genetic basis of this metabolic adaptation was characterized by whole exome sequencing that identified mutations in signaling pathway regulators of growth and energy metabolism. Remarkably, our integrated approach identified rewiring in glycolysis, TCA cycle, …

Articles, Abstracts, and Reports

BACKGROUND: The H&E stromal tumor-infiltrating lymphocyte (sTIL) score and programmed death ligand 1 (PD-L1) SP142 immunohistochemistry assay are prognostic and predictive in early-stage breast cancer, but are operator-dependent and may have insufficient precision to characterize dynamic changes in sTILs/PD-L1 in the context of clinical research. We illustrate how multiplex immunofluorescence (mIF) combined with statistical modeling can be used to precisely estimate dynamic changes in sTIL score, PD-L1 expression, and other immune variables from a single paraffin-embedded slide, thus enabling comprehensive characterization of activity of novel immunotherapy agents.

METHODS: Serial tissue was obtained from a recent clinical trial evaluating loco-regional cytokine …
