Professional overview

Dr. Mary M. Brennan is the Program Director of the Adult-Gerontology Acute Care Nurse Practitioner Program at New York University's Rory Meyers College of Nursing. She received her MS from Boston College and a DNP from Case Western Reserve University. 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.


As an educator, 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. She has designed a virtual hospital called "Acute Care General Hospital" with a contextualized learning environment that provides students with multiple opportunities to practice clinical decision-making. Most recently, she has led an interprofessional curricular initiative with the NYU Dental and Nutrition Programs, focused on developing video case studies to promote collaboration in meeting the nutrition, oral health and systemic health needs of hospitalized adult patients (NOSH Initiative). She is the lead author of a systematic review team, part of the Cochrane Oral Health Group, investigating the effectiveness of whitening toothpastes. In her practice, Mary specializes in the provision of advanced practice nursing care for hospitalized patients with acute, critical, and chronic cardiovascular illnesses.

Practice patterns and organizational commitment of inpatient nurse practitioners

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
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

Evaluation of the clinical hour requirement and attainment of core clinical competencies by nurse practitioner students

Hallas, D., Biesecker, B., Brennan, M., Newland, J. A., & Haber, J. (2012). Journal of the American Academy of Nurse Practitioners, 24(9), 544-553. 10.1111/j.1745-7599.2012.00730.x
Abstract
Purpose: The purpose of this study was to analyze the national practice of fulfilling 500 clinical hours as a requirement for graduation from nurse practitioner (NP) programs at the master's level and to compare this standard to a comprehensive approach of evaluating attainment of clinical competencies. Data sources: The National Organization of NP Faculties (NONPF) and specialty accreditation bodies publications were used for references to clinical hour and core competency requirements for graduation from NP programs. Data from one university from student documentation on a commercial electronic tracking system were also analyzed. Conclusions: Data analysis revealed that the 500 clinical hours correlated to populations, skills performed, required levels of decision making, and expected diagnoses. However, assurance that these clinical hour requirements translated to exposure to all core competencies for entry into practice could not be established. Implications for practice: A more comprehensive approach to the evaluation of student core competencies by implementing one or more performance-based assessments, such as case-based evaluations, simulations, or objective structured clinical examinations (OSCEs), as a strategic part of NP evaluation prior to graduation is proposed. This change is viewed as critical to the continued success of NP programs as master's level education transitions to direct BS to DNP educational preparation for advanced nursing practice.

Evidence-based care for patients with acute coronary syndrome in New York City

Abstract
This chapter describes an innovative model of emergency cardiac care, designed by an academic medical center for residents living in the high-disparity community of East Harlem in New York City. Due to the socioeconomic, racial, and ethnic disparities experienced by individuals living in this community, residents experience the second highest rate of premature death in New York. With a state-of-the-art cardiac catheterization center, cardiologists, partnering with nurse practitioners, collaborate to utilize the best available evidence to assess, diagnose, and treat patients with acute coronary syndrome. This innovative model has resulted in a dramatic reduction of mortality rates involving both nonemergency and emergency patients as well as an improved safety record that has surpassed other New York State Hospitals since reporting of data began in 1994.
