Patients Undergoing Hip or Knee Arthroplasty in Poland Based on National Data-Challenge for Healthcare in Aging Society.

Arthroplasty procedures are more frequently performed due to their impact on the quality of life. The aim of this study was to evaluate and analyze the Polish national datasets and registries for hip and knee arthroplasty across Poland in order to describe and understand the challenges for healthcare in an aging society. The study included national data on 83,525 hip or knee arthroplasties performed in 2017. Of those, 78,388 (93.8%, 63.0% females) were primary operations: 66.6% underwent hip replacement surgery (HPRO, mean age 68.43 years, SD 11.9), and 5137 were secondary operations (females: 62.9%), with 75.2% of those being HPRO (mean age 69.0 years, SD 12.0). The mean age of the patients undergoing knee surgery (KPRO) was 68.50 years (SD 8.2). The majority (79.9%) were scheduled. The main reason for hospitalization was arthrosis (84.2% in total, HPRO-76.5%, and KPRO-99.5%), then trauma (15.1%; < 0.001). In 5137 cases (6.2%, 62.9% females) in revision surgery group, 75.2% underwent HPRO (mean age 69.0 years; SD12.0), and 24.8% KPRO (mean age 68.0 years; SD 10.5). Similarly, 71.1% were scheduled. The main reason for hospitalization was complications (total-90.9%, HPRO-91.4%, and KPRO-89.4%) ( < 0.001). Comorbidities were present (over 80%) with the level of influenza, hepatitis B vaccination, and pre-hospital rehabilitation not exceeding 8% each in both groups. Due to the increasing age of patients, implicating comorbidities, there is a need for better preparation prior to surgery.
