OBJECTIVES: The aim of our prospective study is to compare health state score of patients with femoral neck fracture at the time of primary treatment in hospital and at 1.5 years after treatment by using EQ-5D questionnaire. METHODS: The validated version of EQ-5D questionnaire was filled in at first on the 6-8th day after primary treatment of femoral neck fracture in hospitals, than later 1.5 years after surgical treatment at home. Patients filled in the questionnaires with the assistance of interviewer at 6-8th day and it was posted to them 1.5 years later to their home (control value). Patients with polytrauma were excluded from the study. We compared the health state score of patient filled in both questionnaires according to gender, activity (active/non active), marital status (married/single), education (high school/or lower), residence (town/village), type of operation (osteosynthesis/prosthesis). RESULTS: Altogether 134 patients (97 women and 37 men) fill in both questionnaires. Their mean age was 73.05 ± 10.75 years (min.40 years, max 92 years). The mean health statues score of all patients was 0.548 at 6-8th day and 0.433 at 1.5 years later. According to gender: female: 0.539 and 0.451; male: 0.572 and 0.383 (statistical test: P=0.205). Type of operation: ostheosynthesis: 0.395 and 0.437; arthroplasty: 0.605 and 0.431 (P=0.073). Residence: town: 0.598 and 0.494; village: 0.5 and 0.373 (P=0.053). Education: at least high school: 0.651 and 0.456; below high school: 0.482 and 0.417 (P=0.160). Marital status: single: 0.481 and 0.418; married: 0.629 and 0.452 (P=0.303). Activity: non active: 0.537 and 0.423; active: 0.702 and 0.518 (P=0.278). Age (P:0,057). CONCLUSIONS: The personal opinion on health status showed a deterioration 1.5 years following femoral neck fracture, which is determined mainly by age, residence, type of operation and education. Our study will be completed later by inclusion health status data from visual analogue scale.
