IntroductionCurrent management strategies in nursing homes (NH) aim to ensure effective knowledge management (KM) in order to provide both best possible services to residents, and care for staff in NH. Teamwork in NH is essential for effective delivery of the highest quality of services. As a result, NH are increasingly adopting KM activities to enable knowledge creation, storage, transfer, and implementation in an environment facing many challenges such as lack of staff, increasing demands, and expectations of residents.MethodsIn our quantitative study, we examined how two Slovenian state NH that adopted the E-Qalin quality management model (European quality-improving learning model) adapted their KM, and what impact their quality management system and KM activities actually have on the quality of services. Furthermore, we examined how two Slovenian private NH that have not adopted a certified quality management program (like ISO or E-Qalin) tackle the issue of quality of services from the KM perspective. The sample consisted of 80 nursing professionals. In every NH that is part of this study, teamwork is essential and every individual that was involved in our survey is part of a team. In our study, we analyzed relationships between individual variables using linear regression.ResultsWe found a significant and positive relationship between knowledge creation, transfer, and implementation in NH with and without the E-Qalin certificate. We found a significant and positive relationship between knowledge storage and the quality of services only in NH without a E-Qualin certificate. It seems that when connecting multidisciplinary fields such as NH and KM, there is still a lack of awareness and knowledge on the topic of KM, which might be one of the reasons for some bias in the answers provided by respondents. We also found different teamwork approaches in NH with and without a E-Qalin certificate. Our research results therefore emphasize the need to gain additional insight into quality management and KM in the environment of NH.ConclusionTeamwork based on knowledge storage, transfer, the implementation of existing knowledge, and creation of new knowledge are essential for well-trained professionals and, as a result, contribute to continuous improvement in service quality. Implementation of KM is well received by NH, and enables them to better meet the needs and expectations of residents. More importantly, nursing staff also share and pass on tacit knowledge through teamwork. Finally, all of the NH in our study that implemented quality and KM activities noted an improvement in the quality of services that are offered to residents in practice. Our results indicate that the topic of KM in NH is interesting, and it has a positive impact on the quality of services in practice. However, the problem of awareness and knowledge on the topic of KM in the environment of NH still exists, highlighting the need for further research, additional insight, and dissemination of knowledge to every interested stakeholder functioning in the field of NH. The results of the study make an important contribution to the research of KM in NH, focusing on the transfer of tacit knowledge.
