AbstractPURPOSE OF THE STUDY Anxiety may have negative repercussions on the surgery including poorer outcomes. On the other hand, the majority of patients reporting preoperative anxiety fear not receiving enough attention from a caregiver. In patients undergoing fast-track knee arthroplasty, we determined the relationship between patients' preoperative anxiety and the anxiety the patient's caregiver. We also analyzed the influence of selected psychosocial and demographic variables on the relationship between caregivers' and patients' anxiety. MATERIAL AND METHODS We conducted a prospective, descriptive study in which baseline assessments of patients scheduled to undergo fast-track total knee arthroplasty between 1st November 2014 and 30th April 2015 were compared with those of their caregivers. Patients were recruited from a large teaching hospital through the orthopedics joint replacement clinic. Information on sex, age, body mass index (BMI), educational status, employment status, marital status, and living status was recorded for all patients. Patients and their caregivers completed the Spielberger State-Trait Anxiety Inventory. Baseline trait anxiety was assessed with STAI scores in the initial interview, 2 weeks before hospitalization, and state anxiety was assessed the day before the surgery. The patients' caregivers were contacted during a scheduled postoperative clinic visit and asked to complete the STAI and to provide information on their age, degree of consanguinity with patient, and living status. RESULTS The mean age was 66.4 years for the 118 patients and 55.7 years for the 93 caregivers. In male caregivers, caregiver anxiety and patient anxiety were positively related but not statistically so, and in women was not significant. In male patients, a relationship between caregiver's anxiety and patient's anxiety was positive, although not statistically significant, and in women was neither present nor significant. DISCUSSION Given the widespread impacts of anxiety before knee arthroplasty, it is critical for surgeons to gain a better understanding of how to identify and reduce preoperative anxiety in operated patients. We found that male sex among caregivers was associated with more preoperative anxiety among patients than was female sex and that male patients more quickly accepted anxiety from their caregivers than did female patients. CONCLUSIONS Anxious male caregivers appear to impart their anxiety to male patients but not to female patients. The anxiety of unrelated caregivers is associated with low preoperative anxiety among patients. Preoperative interventions should focus on caregivers, especially male caregivers, and to related caregivers to help patients cope with anxiety before knee arthroplasty.
