Aim: To examine the association between interpersonal relationships, nursing leadership and patient safety culture and the impact on the efficiency of hospitals. Background: Hospitals are still affected by the increased complexity of the treatments offered and by the diverse knowledge of professionals involved, which has made this assistance model ineffective, expensive and unsustainable over time. Method: A qualitative study of 32 professionals from three large hospitals in Southern Brazil was made. Semi-­structured interviews, document analysis and analysis of electronic records were used. Results: All the hospitals had infection rates and an average stay higher than their goal. Lack of interpersonal relationships and physicians failing to commit to organisational objectives were demonstrated. Conclusion: Nursing leadership styles are not definitive factors to improving patient safety and efficiency. The flaws in consolidating interpersonal relationships seem to be related to difficulties in consolidating patient safety culture, which prevented hospitals reaching their efficiency indicators. Implications for Nursing Management: Professionals who work at the patients’ bedside should be involved in the development of strategies, in order to commit them to the organisational objectives. The consolidation of interpersonal relationships of nursing professionals can lead to improvements with medical professionals, with positive impacts on patient safety and efficiency. KEYWORDS

The existing failures in communication, leadership and trust evidenced in the three hospitals are the possible causes to not consolidate the inter-­professional relationships that reflects on their capacity to provide a service with a higher quality (Kaynak & Hartley, 2008) represented here by higher infection and average stay rates.

As communication is poor and the professionals who work at the patients’ bedside do not participate in the planning process, they may not understand how important it is to perform the task requested as well as to perform it in the best way possible (Bisel et al., 2012). The environment found in all hospitals does not seem to be that of cooperation or trust (Yoon et al., 2016). This context is reflected in the way the mistakes are handled, especially in Hospitals A and C. The reports show that they are handled both as a learning source and as a

have low adherence to hand hygiene or error reporting (Yoon et al., 2016). This suggests a distance between two professional categories that should work in an integrated way, which makes it difficult to improve routines that could mitigate the mistakes made (Vogus & Sutcliffe, 2007).

This lack of inter-­professional relationship between nursing staff reflects in losses for the patient safety culture (Morello et al., 2013) and it is evidenced by the infection rates and average stay that are always higher than the goal they have established, for which no one seems to be responsible. If interpersonal relationships do not occur even among the nursing staff, it can be expected that it will not happen between the physicians and nursing staff either. It is not by chance that, only in AICUs, the discharge planning occurs as there is a contractual relationship between the physicians and the hospital (Rafter et al., 2015). The physician’s autonomy, a barrier to the interpersonal relationships, is also related to the quality of the relationships among these physicians and the nursing staff, which reflects in a higher average stay rate as well as in poor utilization of surgical rooms. Physician’s autonomy seems to be related to the commitment and intention of the nursing professionals to leave the organisation. Some reports reveal a high turnover in the three hospitals and that physicians put themselves apart from the care processes or use communication by screaming in surgical rooms (Rafter et al., 2015).

6 |  CONCLUSION Flaws in consolidating interpersonal relationships, trust, leadership and communication seem to be related to the difficulties in carrying out the patient safety culture, which has prevented all hospitals reaching the efficiency indicators. As several professionals could not be involved in simple actions, such as hand hygiene, the risk of associated infections is increased, which implies a failing of patient safety, leading to an increased average length of stay. These considerations suggest that changing only the profile of formal leaders does not guarantee a successful implementation of the patient safety culture. Regarding the limitations of this study and the lack of economic data that could not be accessed to assist in the comparison of the efficiency of the three hospital organisations, a replication of this study in other national and international units would be interesting.
