InspeCKD: Secondary Data Analysis of Patients at Risk for CKD to Inspect CKD Prevalence, Diagnosis Rates, Diagnostic Behaviour, Treatment Patterns and Patient Characteristics
Study Details
Study Description
Brief Summary
This study is a national secondary data analysis to determine the prevalence of diagnosed and undiagnosed CKD in German primary care offices in a patient population at high risk for the development and progression of CKD. Furthermore, it addresses the question of how CKD screening, monitoring and treatment of these patients is conducted within the German primary care setting.

Detailed Description
The study does not attempt to test any specific a priori hypothesis; it is descriptive only. Data on general patient characteristics, health insurance details, participation in disease management programs and/or family doctor-centred care, diagnoses, prescriptions, surgeries, and procedures, used billable services and laboratory test results are documented during daily routine by the physician. The data used in this setting are part of routine visits, dating back a maximum of 24 months from the date of first data transfer within the study period.
