Comparing interventions to lower blood pressure in chronic kidney disease

Questionnaire: How confident are General Practitioners & the Primary care team in managing Chronic Kidney Disease (CKD)

This questionnaire is part of a multi-centre study that aims to test the effects of two quality improvement interventionsagainst usual practiceon the quality of management of CKD. The primary outcome measure of this study is the control of systolic blood pressure among patients with CKD.

Please complete all the questions. The questions ask about your confidence in management of patients with CKD. Some require you to select your personal threshold for intervention. The confidence questions are on a Likert Scale, with 1 representing ‘Not at all confident’, 2 ‘Not confident’, 3 ‘Neither confident nor not confident’, 4 ‘Confident’, 5 ‘Very confident’. Each section compares your confidence in practice in a clinical area using the Likert Scale above.

The information provided by you is strictly confidential. You or your practice will not be identified in any reports or publications that may result from this study.
