Background:
     
     Head nurses face challenging job content while executing their roles as nurses, managers and leaders. However, no European compilation for portraying head nurses' job content within a hospital setting is available.
   

Objectives:
     
     This study aimed to develop and validate a compilation that portrays the job content of head nurses employed in European hospitals.
   

Methods:
     
     A scoping review was conducted according to Arksey and O'Malley's (2005) five-stage framework. Articles focusing on the job content of head nurses with 24-h first-line organizational and hierarchical responsibility for one or two units in a hospital setting were included. An electronic search was performed via PubMed, CINAHL and Embase. The Journal of Nursing Administration, Journal of Nursing Management, Journal of Healthcare Management and Nursing Management were screened manually to identify additional articles. Subsequently, a two-round multinational Delphi study following the methodology of Yussof (2019) was carried out. Eligible opinion leaders originated from Europe and included head nurses, as well as second-line nurse managers and hospital executives with head nurse experience. Twenty-three opinion leaders participated in the first round of the Delphi study, and 16 opinion leaders from the initial round subsequently participated in the second round. The item-level content validity index and scale-level content validity index based on the average method were calculated.
   

Results:
     
     The scoping review included 90 articles published between 1934 and 2024. In total, 64 terms were found to name the head nurse position. Job content could be categorized according to four main themes: operational management, patient care, human resources management and unit-level policy development. Fifteen subthemes were determined, namely quality and safety management, staff planning, administrative and financial management, resource and technology management, care planning, direct and indirect patient care, individual and general staff management, learning opportunities, strategic management, creative thinking, and change management. After two Delphi rounds, the final compilation comprises four main themes, 10 subthemes and 53 task descriptions, excluding staff planning, care planning, direct patient care, administrative management and financial management.
   

Conclusions:
     
     Head nurses' job content mapped by international evidence differs from the job content considered relevant by European opinion leaders. Fragmentation in what European opinion leaders considered relevant within the head nurses' job content became apparent. The compilation can be tailored to different countries or types of hospitals and serve as a guide for second-line nurse managers and hospital executives to determine the key job content based on the priorities and strategic direction of the hospital.
