Development and validation of a questionnaire assessing discrepancy between patients' pre-surgery expectations and abilities and post-surgical outcomes following knee replacement surgery.

Purpose: The discrepancy between patient-desired outcomes and achievable functional outcomes is a source of patient dissatisfaction. This paper reports development and validation of a questionnaire to assess this discrepancy in patients undergoing knee replacement surgery.

Methods: The initial questionnaire (Knee Surgery Perception Questionnaire, KSPQ) comprised two parts.

Effect of lipid exposure on graft patency and clinical outcomes: arteries and veins are different.

Objectives: We evaluated the influence of lipid exposure upon conduit patency in long-term follow-up after primary CABG.

Methods: From a prospectively compiled database, we identified 1207 grafts (436 SV and 771 mixed arterial grafts) among 413 CABG patients with 9.4 ± 2.

Cardiac Depression Scale: Mokken scaling in heart failure patients.

Background: There is a high prevalence of depression in patients with heart failure (HF) that is associated with worsening prognosis. The value of using a reliable and valid instrument to measure depression in this population is therefore essential. We validated the Cardiac Depression Scale (CDS) in heart failure patients using a model of ordinal unidimensional measurement known as Mokken scaling.

Long-term impact of radial artery harvest on forearm function and symptoms: a comparison with leg vein.

Objective: The radial artery (RA) has gained popularity as a conduit for coronary artery bypass surgery despite a paucity of patient-centered analysis of long-term quality of life after its removal. We sought to characterize forearm function and symptoms after RA harvest and compare these with those associated with saphenous vein (SV) removal.

Methods: A total of 408 patients from an RA trial completed a questionnaire up to 14 years after primary coronary artery bypass surgery.

Lipid management in high risk coronary patients: how effective are we at secondary intervention?

Objective: To assess the proportion of patients who achieve and maintain target lipid levels during optimum long term follow up after coronary bypass surgery.

Methods: From a prospectively compiled database, we identified 440 patients followed for up to 13 years after CABG as part of a radial artery randomised controlled trial. All available lipid assays conducted during the follow-up period were collected from pathology databases.

Development and validation of the Diabetes Management Orientation Scale (DMOS): assessing culturally related approaches to diabetes self-management.

Aims: Self-management behaviours of type 2 diabetes are improved by self-efficacy while the role of culture is not well understood. This study explored cultural individualist and collectivist aspects of self-management and their relationship to diabetes control.

Methods: 94 Adults with type 2 diabetes for over 1 year and Chinese spoken as a first language at home recruited through healthcare providers completed the newly developed Diabetes Management Orientation Scale (DMOS), and a validated Diabetes Self-Efficacy Scale (DSES).
