Patient involvement in treatment decision-making: the case for a broader conceptual framework

OBJECTIVE: To consider the conceptualisation of patient involvement in treatment decision-making. METHOD: Conceptual review. RESULTS: Current models and measures of patient involvement in treatment decision-making tend to focus on communication within consultations and/or on the patient's use of information to consider the selection of one treatment option from a well-defined set. These narrowly focused models and measures may obscure the relevance of patient involvement in decision-making for some health care contexts and limit investigations of the relationships between patient involvement in decision-making and health care outcomes. We outline a broader conceptual framework that reflects more of the complexity of the concept of involvement. It acknowledges that patients can be involved not only because of what they say and do to influence a decision, but also by virtue of what they think and feel about their roles, efforts and contributions to decision-making and their relationships with their clinicians. The framework encompasses the full range of activities associated with decision-making. CONCLUSION: The proposed conceptual framework may broaden the relevance of patient involvement in decision-making and encourage a more comprehensive characterisation that may facilitate more sophisticated investigations of the relationships between patient involvement in decision-making and health care outcomes. PRACTICE IMPLICATIONS: Clinicians who aspire to facilitate patient involvement in decision-making need to look beyond the way they discuss health care options with patients. They should also consider how they might enable patients to engage in the full range of decision-making activities and to develop a positive sense of involvement in these activities and with their clinicians.     

Preoperative psychosocial risk factors for poor outcomes at 1 and 5 years after total knee replacement

Background and purpose — Psychosocial factors are important risk factors for poor outcomes in the first year after total knee replacement (TKR), however their impact on long-term outcomes is unclear. We aimed to identify preoperative psychosocial risk factors for poor outcomes at 1 year and 5 years after TKR.

Patients and methods — 266 patients were recruited prior to TKR surgery. Knee pain and function were assessed preoperatively and at 1 and 5 years postoperative using the WOMAC Pain score, WOMAC Function score and American Knee Society Score (AKSS) Knee score. Preoperative depression, anxiety, catastrophizing, pain self-efficacy and social support were assessed. Statistical analyses involved multiple linear regression and mixed effect linear regression.

Results — Higher anxiety was a risk factor for worse pain at 1 year postoperative. No psychosocial factors were associated with any outcomes at 5 years postoperative. Analysis of change over time found that patients with higher pain self-efficacy had lower preoperative pain and experienced less improvement in pain up to 1 year postoperative. Higher pain self-efficacy was associated with less improvement in the AKSS up to 1 year postoperative but more improvement between 1 and 5 years postoperative.

Interpretation — Preoperative anxiety was found to influence pain at 1 year after TKR. However, none of the psychosocial variables were risk factors for a poor outcome at 5 years post­operative, suggesting that the negative effects of anxiety on outcome do not persist in the longer-term.
