BACKGROUND - METHODS - RESULTS - CONCLUSION - LEVEL OF EVIDENCE; The proximal humeral fracture (PHF) is the third most common fracture in older individuals. Prior level of care (LoC) and associated comorbidities may have an impact on patient outcome and prognosis.; Retrospective German health insurance data from patients with PHF aged 65 years and older between 01/17 to 09/22 were analysed. The primary endpoints included overall survival (OS), major adverse events (MAEs), thromboembolic events (TEs), and surgery- or injury-related complications. All endpoints were analysed using multivariable models.; A total of 55,798 patients (median age 79 years; 84% female) were included. Prior to PHF, 68% had no LoC (LoC I 3%, LoC II 12%, LoC III 11%, LoC IV 6%, LoC V 1%), and 8% were living in a nursing home. With increasing LoC, the proportion of patients receiving non-operative treatment (no LoC 52%, LoC I 53%, LoC II 62%, LoC III 64%, LoC IV 71%, LoC V 76%) and the likelihood of a worse outcome increased. Both, mortality rates (1-year mortality: no LoC 4%, LoC I 12%, LoC II 19%, LoC III 29%, LoC IV 41%, LoC V 50%) and rates of MAEs increased drastically with increasing LoC. Multivariable analyses confirmed that increasing LoC was associated with a greater risk of death, MAEs, and TEs (all p < 0.001).; Prior LoC has a significant effect on the course of PHF and the choice of treatment method in older individuals. This should be considered when making treatment decisions.; Level III, retrospective comparative study.
