Factors Predicting Adoption of the Nurses Improving Care of Healthsystem Elders Program

Stimpfel, A., & Gilmartin, M. (2019). Nursing Research, 68(1), 13-21. 10.1097/NNR.0000000000000327
Background Registered nurses are often underprepared with the knowledge and skills to care for hospitalized older adult patients. One strategy to bridge this gap is for hospitals to adopt the Nurses Improving Care for Healthsystem Elders (NICHE) program: A nurse-led interdisciplinary organizational intervention to improve care of hospitalized older adults. Objectives This study aimed to identify the market, organizational and managerial, and sociotechnical factors associated with the adoption of NICHE among U.S. hospitals in order to understand factors that promote and inhibit the adoption of models to improve care for elders and to provide a basis for future studies that evaluate the effects of NICHE participation on patient outcomes. Methods We used an observational, retrospective design, linking three national administrative data sources, in a secondary analysis. Data included the 2012-2013 American Hospital Association Annual Survey, NICHE database, and the American Nurses Credentialing Center Magnet database. Multivariate logistic regression models were completed at the hospital level (n = 3,506). Results Statistically significant variables associated with hospital adoption of the NICHE program include using a medical home model, being in a network, having a pain services program, being in an urban location, and having over 100 beds. Discussion Understanding factors that promote the adoption of organizational interventions like NICHE holds promise for accelerating the use of evidence-based clinical practices to promote health, function, and well-being for older hospitalized adults. Our results provide a foundation for assessing the effects of NICHE participation on patient outcomes by identifying factors that account for membership in NICHE.

A Self-Efficacy Scale for Clinical Nurse Leaders: Results of a Pilot Study

Gilmartin, M., & Nokes, K. (2015). Nursing Economic$, 33(3), 133-143.
Introduced in 2003, the Clinical Nurse Leader (CNL) role is the first new nursing role introduced in more than 30 years. The hallmark of CNL practice is the management of client-centered care and clinical excellence at the point of care. As part of multifaceted efforts to implement the CNL role, understanding how an individual's self-efficacy with the identified role competencies changes over time has important implications for individuals, educational programs preparing CNLs, and health care organizations employing CNLs. In this study, preliminary psychometric analyses assessing the construct validity, reliability, and discriminant validity for a new state-specific scale (CNL Self-Efficacy Scale) that assesses nurses' perceptions of their ability to function effectively as a CNL are reported. Because self-confidence is a key predictor of successful role transition, job satisfaction, and job performance, measuring individuals' self-confidence with the core competencies associated with the CNL role over time will be important to gain the full benefit of this innovative, unit-based advanced generalist role.

Increasing faculty capacity: Findings from an evaluation of simulation clinical teaching

Richardson, H., Goldsamt, L., Simmons, J., Gilmartin, M., & Jeffries, P. R. (2014). Nursing Education Perspectives, 35(5), 308-314. 10.5480/14-1384
AIM: To compare how the use of different "doses" of simulation in undergraduate clinical teaching affect faculty capacity. BACKGROUND: Since 2008, the NYU College of Nursing has used a "high dose" of simulation to substitute for 50 percent of the clinical hours in core medical-surgical courses to address a shortage of faculty and clinical sites. Johns Hopkins University School of Nursing has used limited, "low-dose" simulation hours to supplement clinical hours. METHOD: The evaluation included program data and surveys and qualitative interviews with faculty and students in each program. RESULTS: Implementing "high-dose" clinical simulation resulted in a nearly 50 percent increase in faculty capacity at NYU, expanding undergraduate enrollment from 613 students in 2007 to 900 in 2012, with no negative impacts on faculty work life or student outcomes. CONCLUSION: Substituting simulation for traditional clinical hours can be a sustainable and educationally sound option to increase faculty capacity.

Variations in clinical nurse leaders' confidence with performing the core role functions

Gilmartin, M. (2014). Journal of Professional Nursing, 30(4), 307-316. 10.1016/j.profnurs.2013.11.002
Clinical nurse leader (CNL) practice, by definition, requires individuals to make career transitions. CNLs must adjust to their new work role and responsibilities and doing so also entails individual adjustment. Prior work has not examined the role of individual-level factors in effective CNL role transition. This study contributes to CNL implementation efforts by developing understanding of personal and contextual factors that explain variation in individuals' levels of self-confidence with performing the key functions of the CNL role. Data were gathered using a cross-sectional survey from a national sample of registered nurses (RNs) certified as CNLs. Respondents' perceptions of their confidence in performing CNL role competencies were measured with the Clinical Nurse Leader Self-Efficacy Scale (CNLSES; Gilmartin MJ, Nokes, K. (in press). The Clinical Nurse Leader Self Efficacy Scale: Results of a pilot study. Nursing Economic$). The CNLSES is a 35-item state-specific self-efficacy scale with established measurement properties that assesses nurses' perceptions of their ability to function effectively as a CNL. Demographic data were also collected. Data were analyzed using a general linear regression model. One hundred forty-seven certified CNLs participated in the survey. Results indicate that respondents vary in their confidence with performing the nine role competencies associated with CNL practice. Results from regression analyses also show that respondents' confidence in their abilities to carry out the core functions associated with the CNL role varied significantly across geographic region, organizational type, and by CNL graduate program model. The results of this study show important differences in CNLs' levels of self-confidence with the core competencies of their role. As a result, it may be important to develop targeted career transition interventions to gain the full benefit of CNL practice.

Principles and practices of social entrepreneurship for nursing

Gilmartin, M. (2013). Journal of Nursing Education, 52(11), 641-644. 10.3928/01484834-20131014-03
Although social justice and action for change are among the nursing profession's core values, curricular content on social entrepreneurship for nurses is not as well developed as it is in the educational programs for students in business, engineering, or public policy. This article describes an undergraduate honors elective course in social entrepreneurship offered at New York University College of Nursing. The course uses a seminar format and incorporates content from the humanities, business, and service-learning, with the goal of promoting participants' understanding of the sources of inequality in the United States and providing the requisite skills to promote effective nursing action for social change.

Thirty years of nursing turnover research: Looking back to move forward

Gilmartin, M. (2013). Medical Care Research and Review, 70(1), 3-28. 10.1177/1077558712449056
Despite the substantial amount of useful prior work on turnover among nurses, our understanding of the causal mechanisms explaining why nurses voluntarily leave their jobs is limited. The purpose of this article is to promote the development of stronger conceptual models of the causes of voluntary turnover among nurses. The author compares the nursing-specific literature to research on voluntary turnover from the general management field over the past 30 years and examines the evolution of key theories used in the nursing literature. Results of this review comparing nursing research with that in the broader field suggest that, over time, nursing research has not kept pace with conceptualizations from general management explaining why people either remain at or quit their jobs. The author argues that conceptual models of turnover among nurses can benefit significantly from drawing more effectively on particular models and concepts available in general management studies of turnover.
