Biopsychosocial complexity in patients scheduled for elective TKA surgery

A feasibility pilot study with the INTERMED self-assessment questionnaire

Article

Objective: Primary aim; to determine the feasibility of implementation of the INTERMED Self-Assessment (IM-SA) in adult patients scheduled for total knee arthroplasty (TKA). Secondary aim; to measure biopsychosocial complexity, referral to psychiatry or psychology in cases of complexity and to gain insight into the relation between biopsychosocial complexity and length of stay (LOS), method of discharge (MOD) and polypharmacy. Methods: A feasibility study was conducted with 76 participants in a general hospital in the Netherlands. Feasibility was determined by the number of completed questionnaires, time spent completing the questionnaire and the attitude of staff and patients towards the IM-SA. A cut off point ≥19 on the IM-SA was used to determine the prevalence of biopsychosocial complexity. A case file study was performed to check if referral to psychiatry or psychology had taken place. The Spearman's Rank Correlation Coefficient or Phi was used to determine if there was a relation between biopsychosocial complexity and LOS, MOD and polypharmacy. Results: All participants completed the IM-SA. The average time spent completing the questionnaire was 11.46 min (SD 5.74). The attitude towards the IM-SA was positive. The prevalence of biopsychosocial complexity was 11.84%. Referral to psychiatry or psychology did not take place. There was no relation between complexity and LOS (Spearman's rho (r) = 0.079, p = 0.499, MOD (Phi = 0.169, p = 0.173) and polypharmacy (Phi = 0.007, p = 0.953). Conclusion: Biopsychosocial complexity can be identified in TKA patients during the pre-operative phase by using the IM-SA. Implementation of the IM-SA in a Dutch general hospital is feasible.
