Introduction: The frequency and clinical impact of chronic kidney disease (CKD) in type 2 diabetes patients (DM2) and the benefits of early intervention highlights the need for close collaboration in detection and management between Nephrology and Primary Health Care.
Objective: Our objectives were to estimate the prevalence of CKD in DM2 patients controlled by primary care and evaluate the need to early referral of CKD DM2 patients to renal specialists.
Study population: patients older than 18 years of age, with analysis made for any reason in the 16 Health Centers of Health Sector Alcañiz (84,340 inhabitants)during 2008.
Variables: age, sex, serum creatinine,urine albumin/creatinine ratio, glycated hemoglobin,potassium and hemoglobin. We calculated the estimated glomerular filtration rate (eGF) by the MDRD formula. Were viewed the Consensus Document S.E.N.-SEMFyC ERC 2008 criteria for referral to renal specialists.
Results: Of the 16,814 patients enrolled, 3,466 (20.6%) had DM2. In DM2 patients, the prevalence of CKD was 34.6% (IC 95%, 33-36.2). eGF <60 ml/min/m2 was recorded in 25.2% of DM2 patients. In this subgroup the prevalence of albuminuria was 31.7%. Met criteria for referral to renal specialists 104 (3%) DM2 patients and 132 (1%) non diabetic patients(p <0.0001).
Conclusions: The prevalence of DM2 in the Health Centers is high, with frequent presence of CKD and albuminuria. An important percentage of patients meets the referral S.E.N.-SEMFyC criteria. The collaboration with primary care is essential in early detection and monitoring of these patients, and common primary care and nephrology protocols are need.Key words: Chronic kidney disease.
