Over the past decade, theoretical and empirical research on the various aspects of human resources (HR) within the healthcare (HC) sector has grown extensively due to its′ strategic importance in the sector. There is a visible tendency among researchers to pursue an effective human resource management (HRM) strategies, methods, and tools. Countries implement policies which should increase the amount and competences of employees within healthcare. Providers of HC services (i.e. hospitals) tend to enforce modern HRM solutions adapted from business organisations to attract, retain and develop HR. However, these seem not be as effective as they could (Hyde et al., 2013). Because of this, authors approached a researched reality from the point of view of a contextual paradigm, assuming that HRM solutions to be effective should match the reality of HC providers (Pocztowski, 2008). The aim of the research was to detect determinants which might influence the management of medical personnel in hospitals and identify the possible strength of these determinants so a more adjusted organisational and human resource management strategy could be elaborated. The list of possible determinants of hospital operations as the result of meta-analysis was elaborated. The list created the basis for interviews conducted among stakeholders and experts. Respondents were asked to appraise the factors with the usage of numerical scale considering their influence on medical personnel management in hospitals (physicians, nurses and others). In total, there were 28 interviews completed. The general conclusion which can be drawn from the analysis of these data is that hospitals should reorient their HRM practices in such the way that not only the quantitative but also the qualitative aspect of performance would be properly handled. This paper draws from HRM theory (contextual approach), stakeholder theory, and healthcare management theory, adding new insight to each in the context of the HC sector. Identification of most important factors which influence hospitals could allow the providers to elaborate HRM strategy adjusted to external circumstances.
