Purpose The aim of this retrospective study was to identify independent prognostic factors for developing a postoperative delirium (POD) in patients suffering from a proximal femoral neck fracture and treated by implantation of a hemiprosthesis. Methods A retrospective study, including patients with hip hemiarthroplasty due to a femoral neck fracture between 2011 and 2020 was performed. Demographic data, preexisting conditions, intra-/postoperative complications, mobilization and laboratory results were extracted from the patients’ charts. The different parameters were analyzed comparing patients with and without POD. Results 412 patients, mean age of 81 ± 9.58 years were included, 66.5% ( n  = 274) were female, 18.2% ( n  = 75) of them developed a POD. Significantly higher incidence of POD was associated with older age ( p
