ABSTRACT Hospital organizational culture is widely held to matter to the delivery of services, their effectiveness, and system performance in general. However, little empirical evidence exists to support that culture affects provider and patient outcomes; even less evidence exists to support how this occurs.
To explore causal relationships and mechanisms between nursing specialty subcultures and selected patient outcomes (i.e., quality of care, adverse patient events).
Martin's differentiation perspective of culture (nested subcultures within organizations) was used as a theoretical framework to develop and test a model. Hospital nurse subcultures were identified as being reflected in formal practices (i.e., satisfactory salary, continuing education, quality assurance program, preceptorship), informal practices (i.e., autonomy, control over practice, nurse-physician relationships), and content themes (i.e., emotional exhaustion). A series of structural equation models were assessed using LISREL on a large nurse survey database representing four specialties (i.e., medical, surgical, intensive care, emergency) in acute care hospitals in Alberta, Canada.
Nursing specialty subcultures differentially influenced patient outcomes. Specifically, quality of care (a) was affected by nurses' control over practice, (b) was better in intensive care than in medical specialty, and (c) was related to lower adverse patient events; nurses in intensive care and emergency specialties reported fewer adverse events than did their counterparts in medical specialties.
Understanding the meaning of subcultures in clinical settings would influence nurses and administrators efforts to implement clinical change and affect outcomes. More research is needed on nested subcultures within healthcare organizations for better understanding differentiated subspecialty effects on complexity of care and outcomes in hospitals.

    ABSTRACT: Purpose This paper reports an analysis of the concept of patient outcomes. Methods The Walker and Avant concept analysis approach was applied. Results The attributes of patient outcomes include (1) patient functional status (maintained or improved), (2) patient safety (protected or unharmed), and (3) patient satisfaction (patient reporting of comfort and contentment). These attributes are influenced by the antecedents of individual patient characteristics and health problems, the structure of healthcare organizations and received health interventions. Additionally, patient outcomes do significantly impact the quality of nursing care, the cost of effective care and healthcare policy making formulation. Conclusion Providing good nursing care to all patients is a central goal of nursing. Patient outcomes in nursing are primarily about the results for the patient receiving nursing care. This analysis provides nurses with a new perspective by helping them to understand all the components within the concept of patient outcomes.

    ABSTRACT: To identify factors associated with intent to stay in hospital among five different categories of healthcare professionals using an adapted version of the conceptual model of intent to stay (CMIS). /st>A cross-sectional survey targeting Lausanne University Hospital employees performed in the fall of 2011. Multigroup structural equation modeling was used to test the adapted CMIS model among professional groups.MeasuresSatisfaction, self-fulfillment, workload, working conditions, burnout, overall job satisfaction, institutional identification and intent to stay. /st>Surveys of 3364 respondents: 494 physicians, 1228 nurses, 509 laboratory technicians, 935 administrative staff and 198 psycho-social workers. /st>For all professional categories, self-fulfillment increased intent to stay (all β > 0.14, P < 0.05). Burnout decreased intent to stay by weakening job satisfaction (β < -0.23 and β > 0.22, P < 0.05). Some factors were associated with specific professional categories: workload was associated with nurses' intent to stay (β = -0.15), and physicians' institutional identification mitigated the effect of burnout on intent to stay (β = -0.15 and β = 0.19). /st>Respondents' intent to stay in a position depended both on global and profession-specific factors. The identification of these factors may help in mapping interventions and retention plans at both a hospital level and professional groups' level.
