Mary M. Brennan, AGACNP-BC, ANP, CNS, DNP, FAANP, is the program director of the Adult-Gerontology Acute Care Nurse Practitioner Program and a clinical associate professor at NYU Rory Meyers College of Nursing. In her clinical practice, Brennan specializes in the provision of advanced practice nursing care for hospitalized patients with acute, critical, and chronic cardiovascular illnesses. She has developed an innovative, problem-based curriculum, using evidence-based practice, to cultivate the art and science of clinical decision-making for adult patients with acute, critical, and chronic illnesses. As an educator, Brennan is interested in cultivating nurse practitioners' critical thinking and decision-making. As a DNP and an expert in quality improvement initiatives, Brennan teaches in the DNP Program and serves as a faculty mentor for a number of DNP students.

Brennan has received several curricular development challenge grants to design a virtual hospital called "Acute Care General Hospital," providing students with multiple opportunities to practice the assessment, diagnosis, and treatment of patients. Brennan has integrated a series of progressive simulations throughout the AGACNP Program, and has presented her work nationally and internationally on rapid-response simulations at the National Organization of Faculty Conference and the International Nursing Association for Clinical Simulation and Learning Conference. She serves on NONPF's simulation committee. In collaboration with the Silver School of Social Work and the Long Island College of Pharmacy, Brennan is integrating interprofessional simulations throughout the AGACNP Program. 

Brennan has also led an initiative in Dar Es Salaam, Tanzania, to develop a culture of safety initiative designed to improve outcomes for patients with cardiac disease. Currently, she is collaborating with a team from Xiangya Hospital, Changsha, Hunan Province, China, to develop a culture of safety assessment in three different hospitals in Sierra Leone. She is the lead author of a systematic review team, part of the Cochrane Oral Health Group, investigating the effectiveness of whitening toothpastes.

In recognition of her exemplary teaching and learning approaches in nursing education, Brennan received the inaugural Dean's Distinguished Teaching Award in 2018.

Brennan earned her DNP from Case Western Reserve University and MS from Boston College. Her DNP project was conducted in Accra, Ghana, where she taught nurses the principles of pediatric resuscitation to improve the care of infants and children treated in the emergency room.

Curricular Quality Improvement in Midwifery: Simulating Unexpected Perinatal Loss

Altman, S. D., Tilley, C. P., Feldman, R., Brennan, M., & Wholihan, D. (2023). Journal of Midwifery and Women’s Health. 10.1111/jmwh.13498
Abstract
Abstract
Introduction: Caring for families experiencing perinatal loss is a fundamental component of midwifery practice, but little attention is paid to perinatal palliative care in midwifery curricula. Lack of educational preparation and self-care resources negatively impacts midwifery students and health care teams caring for families experiencing stillbirth. Process: A private, urban university conducted a curricular quality improvement project to integrate perinatal palliative care into the midwifery curriculum using a high-fidelity, branching simulation pedagogy. Simulation objectives were developed from curricular gap analyses and the Core Competencies for Basic Midwifery Practice. Development of the Unexpected Perinatal Loss Simulation was guided by the International Nursing Association for Clinical Simulation and Learning Outcomes and Objectives and Design Standards. The Unexpected Perinatal Loss Simulation was revised based on qualitative data from student focus groups and expert content validation. Outcomes: Qualitative data yielded 4 key domains: presimulation, simulation skills, prior experience/personal reflections, and recommendations. Simulation procedures and scenario content were revised, after which 8 expert clinicians in the fields of midwifery, palliative care, and psychiatry validated the scenario content using the Lynn method. Two items did not meet the content validity index (CVI) threshold of 0.78, necessitating review by stakeholders; however, the overall scenario CVI threshold was met (0.82). Discussion: Through this project, faculty integrated perinatal palliative care into the midwifery program using a novel approach of high-fidelity, branching simulation, structured debriefing, and an introductory self-care skills workshop. Potential clinical impact includes skillful perinatal palliative care with effective communication skills to mitigate how families experience and remember a traumatic loss and facilitate the grieving process. Students voiced insights into how they would process loss and seek support to mitigate their own grief as future midwives.

Real-time, simulation-enhanced interprofessional education in the care of older adults with multiple chronic comorbidities: a utilization-focused evaluation

Tilley, C. P., Roitman, J., Zafra, K. P., & Brennan, M. (2021). MHealth, 7. 10.21037/mhealth-19-216
Abstract
Abstract
Background: Interprofessional education (IPE) is a curricular requirement for all healthcare professional education standards. To foster learning about, from and with each other, consistent with the Interprofessional Education Consortium’s Core Competencies, many graduate schools are integrating interprofessional (IP) simulation experiences throughout their educational curricula, providing multiple opportunities for health professional students to collaborate and practice together. High-fidelity, real-time simulations help students from diverse professional backgrounds to apply their classroom learning in realistic clinical situations, utilize mobile technology to access clinical decision support (CDS) software, and receive feedback in a safe setting, ensuring they are practice-ready upon graduation. Methods: New York University Rory Meyers College of Nursing (NYU) and Long Island University College of Pharmacy (LIU) partnered for two consecutive years to create, coordinate and implement two interprofessional educational simulations involving patients with chronic cardiovascular disease. A utilization-focused evaluation of high-fidelity, simulation-enhanced IPE (Sim-IPE) was implemented to assess students’ IP competencies before and after their participation in the IPE-simulation and their overall satisfaction with the experience. The Interprofessional Collaborative Competency Attainment Survey (ICCAS), a reliable instrument, was administered to both doctor of pharmacy students and primary care advanced practice nursing students before and after each simulation experience. Additionally, student satisfaction surveys were administered following the IPE-simulation. Results: Aggregated means revealed statistically significant improvements in each of the six domains including communication, collaboration, roles and responsibilities, collaborative patient/family approach, conflict resolution and team functioning. Student ratings revealed positive experiences with the IPE-simulations. Conclusions: High-fidelity, real-time IPE-simulation is a powerful pedagogy to help graduate students from different professional backgrounds practice applying IP competencies in simulated experiences. Quality improvement studies and research studies are needed to assess the impact of high-fidelity, real-time simulations throughout graduate curricula with different types of patients to improve coordinated, team approaches to treatment.

Abstract
Abstract
PURPOSE: Nurse practitioners (NPs) deliver a wide array of healthcare services in a variety of settings. The purpose of this study was to examine the practice patterns and organizational commitment of inpatient NPs.METHODS: A quantitative design was used with a convenience sample (n = 183) of NPs who attended the American Association of Nurse Practitioners (AANP) national conference. The NPs were asked to complete a demographic questionnaire, the Practice Patterns of Acute Nurse Practitioners tool and the Organizational Commitment Questionnaire.CONCLUSIONS: Over 85% of inpatient practice time consists of direct and indirect patient care activities. The remaining nonclinical activities of education, research, and administration were less evident in the NP's workweek. This indicates that the major role of inpatient NPs continues to be management of acutely ill patients. Moderate commitment was noted in the Organizational Commitment Questionnaire.IMPLICATIONS FOR PRACTICE: Supportive hospital/nursing leadership should acknowledge the value of the clinical and nonclinical roles of inpatient NPs as they can contribute to the operational effectiveness of their organization. By fostering the organizational commitment behaviors of identification, loyalty, and involvement, management can reap the benefits of these professionally dedicated providers.

Paediatric resuscitation for nurses working in Ghana: An educational intervention

Brennan, M. M., Fitzpatrick, J. J., Mcnulty, S. R., Campo, T., Welbeck, J., & Barnes, G. (2013). International Nursing Review, 60(1), 136-143. 10.1111/j.1466-7657.2012.01033.x
Abstract
Abstract
Background: Deficiencies in the paediatric emergency systems of developing countries may contribute to avoidable paediatric mortality. Studies suggest that nurses and doctors may not be educationally prepared to provide immediate paediatric resuscitative care to acutely ill children. The purpose of this study was to determine if a 1-day World Health Organization (WHO) Emergency Triage and Assessment Treatment (ETAT) Program in paediatric resuscitation would increase Ghanaian nurses' knowledge and self-efficacy of paediatric resuscitation. Methods: A pre-experimental, one-group, pre-test, post-test design was used to assess differences in the nurses' knowledge of paediatric resuscitation, and their perceived self-efficacy of paediatric resuscitation after completing a 1-day educational intervention in paediatric resuscitation. Forty-one nurses from a public teaching hospital in Ghana were recruited and participated in the study. Results: Using a paired samples t-test, there was a statistically significant increase in the nurses' perceived self-efficacy of paediatric resuscitation in general (P<0.000), perceived self-efficacy of bag and mask ventilation (P<0.000), and knowledge of paediatric resuscitation (P<0.000). Conclusions: Findings from this study suggest that a 1-day WHO ETAT Program may increase self-efficacy of paediatric resuscitation and knowledge of paediatric resuscitation. Clinical Relevance: Policy makers in Ghana need to consider implementing education programmes in paediatric resuscitation for nurses as part of a comprehensive strategy to improve emergency systems and address preventable and avoidable infant and child mortality.
