abstract: Harm to patients remains high in US hospitals despite significant progress to improve the quality of care in our health systems. Leadership, a culture of patient safety, and a climate conducive to innovation in patient care are necessary to advance positive patient safety outcomes. Yet, little is known about how leadership can impact patient safety within a climate of innovation. This study examines the effects of transformational and transactional leadership (singularly and with transactional augmenting transformational leadership) as related to nurses’ perception of patient safety, how communication elements of a culture of patient safety may strengthen that relationship, and how the mediating role of team innovation climate may help explain the relationship between transformational and transactional leadership and nurses’ perception of patient safety. The variables were measured using three validated and reliable survey instruments: The Multifactor Leadership Questionnaire (MLQ Form 5X), the Team Climate Inventory-short (TCI), the Agency for Healthcare Research and Quality (AHRQ) Hospital Survey on Patient Safety Culture. A convenience sample of all staff registered nurses (N=952) from the single academic medical center with direct patient care responsibility was surveyed via e-mail for this research. A total of 210 surveys were returned, 157 met inclusion criteria for a response rate of 16%. Transformational leadership had a statistically significant relationship with patient safety perception, while the relationship of transactional leadership with patient safety perceptions was not significant. The results of the regression analysis that tested the effect of communication elements of a culture of patient safety on the relationship between transactional and transformational leadership and patient safety perception were not significant. Transformational leadership was significantly related with team innovation climate after controlling the effect of transactional leadership supporting the augmentation effect. Mediation analysis showed that team innovation climate had a significant mediating effect on the relationship between transformational leadership and patient safety perception. Team innovation climate had a significant mediating effect on the relationship between managers’ transformational leadership and patient safety perception after controlling for transactional leadership supporting the augmentation effect. This is the first study known to test the augmentation of transformational leadership related to patient safety and the role of team innovation climate. / Dissertation/Thesis / Doctoral Dissertation Nursing and Healthcare Innovation 2019

The methodological strategy used was the multiple-case study, applying a self-assessment questionnaire from the Emergency Care Research Institute (ECRI), translated for the Portuguese language. The questionnaire was applied both to leaders who work directly with patient care and administrative leaders that ensure assistance is not prevented or interrupted, and thus indirectly reflect on patient safety. Qualitative and quantitative questions were graded using a Likert scale and consolidated according to seven dimensions, namely: expectations and safety promotion, support and investment from hospital management, security environment, openness to communication and non-punitive response, organizational learning, teamwork, and feedback (information and communication feedback about errors). Data analysis was performed using the statistical programSTATATM 12.1, whose response sample was subjected to linear regression for analysis of variance (ANOVA), having an F test of joint statistical significance as decision rule , in which the p-value is zero. The analysis of mean values of the groups in the studied organizations, as perceived by the respondents, showed a gradation among organizations, with higher values concentrating in private institutions. However, when assessing the specifics among the dimensions of safety culture used for the data analysis, it was found that, as perceived by the participants of the study, the most significant dimensions are Security Environment and Organizational Learning, with an explanatory power of 80%. In addition, also as perceived by the agents, the correlation between the above-mentioned dimensions is stronger in direct administration organizations, followed by the institutions under governmental autonomous administration. / Considerando que a segurança do paciente é um dos pontos críticos que refletem no desempenho de uma organização hospitalar, o presente estudo teve como objetivo identificar como a segurança do paciente se insere na cultura organizacional de organizações hospitalares do município de São Paulo, de diferentes naturezas administrativas: hospitais públicos de administração direta, hospitais públicos administrados por contrato de gestão e hospitais privados. A estratégia metodológica utilizada foi o estudo de casos múltiplos, com aplicação do questionário de autoavaliação do Emergency Care Research Institute (ECRI), traduzido para a língua portuguesa. Procedeu-se a aplicação do instrumento com as lideranças que atuam diretamente com a assistência aos pacientes e com as lideranças administrativas que garantem que a assistência não seja inviabilizada ou interrompida, e, assim, refletem indiretamente na segurança dos pacientes. As questões, qualitativas e quantitativas, utilizaram uma escala de Likert para sua gradação e foram consolidadas segundo sete dimensões, a saber: expectativas e ações de promoção da segurança, apoio e investimento da gestão hospitalar, ambiente de segurança, abertura para comunicações e respostas não punitivas, aprendizado organizacional, trabalho em equipe e feedback (retorno da informação e comunicação a respeito de erros). Para análise dos dados utilizou-se o programa de estatística STATATM 12.1, cuja amostra de resposta foi submetida a regressão linear para análise de variância (ANOVA), considerando como base decisória um teste F, de relevância estatística conjunta, em que p-valor é igual a zero. A análise das médias de respostas obtidas nos grupos das organizações estudadas, segundo a percepção dos respondentes, evidenciou uma gradação entre as organizações com maiores valores se concentrando nas de natureza privada. Entretanto, ao serem avaliadas as especificidades entre as dimensões da cultura de segurança utilizadas para a análise dos dados, verificou-se que, segundo a percepção dos participantes do estudo, as dimensões significativas foram a do Ambiente de Segurança e Aprendizado Organizacional, com um poder explicativo de 80%. Além disso, também segundo a percepção dos agentes, a correlação entre as dimensões citadas acima foi mais forte nas organizações de administração direta, seguida pelas instituições sob administração autárquica.
