CKD Screening and Prevention Initiatives in Jalisco.

!● Population-based screening ● Targeted Screening -CKD screening program using mobile clinics ● Oportunistic Screening - CKD Screening on WKD !● MDC Prevention Clinic ! !!! ! !

Mobile Clinics Screening Programs

!▪ In operation since 1999 ▪ Diabetes ▪ Hypertension ▪ CA of Cervix ▪ HIV-AIDS ▪ Cataracts

Mobile Clinics CKD Screening Program begins September, 2006

!▪ Mexico’s Secretary of

Health, Dr. Jose Cordova Villalobos, launches the CKD Screening Program. March, 2007

Equipment and Staff

!● 4 mobile units ● 4 Physicians ● 4 Nurses ● 4 Lab Technicians ● Undergraduate students

from the University of Guadalajara Schools of Medicine, Nursing, and Nutrition

Clinical and Lab exams

!● CBC ● Blood Glucose, Creatinine,

Urea ● Pap smear ● Eye examination ● Serum Lipids ● Urianalysis ● Estimated GFR (MDRD) ● BMI ● Blood Pressure

How does it work?

● Community leaders organize the screening program at their communities.

- location of the van - estimated population - number of days of screening. ● Advertising campaign to alert for risk factors for

kidney and CV disease and the benefits of early detection (flyers, radio and pulpit announcements during Sunday mass, mobile loudspeakers in public places, or door-to-door visits by local volunteers)

Follow-up of Findings During Screening

● Individuals found to have hypertension, proteinuria, diabetes or reduced eGFR are informed of the findings.

● They are advised for: A) follow up with their own physician B) Those without phisicians are referred to our subsidized, protocol-driven, multidisciplinary prevention clinic.

CKD Screening Initiatives.

!! ● OPORTUNISTIC SCREENING ! -CKD screening on World Kidney Day !

CKD screening in WKD

Results

● eGFR < 60 ml/min/1.73 m2 prevalence ranges between 1.7% in children and 6.4% in adults.

Conclusions

● Impaired kidney function is frequently detected when mobile units are used to perform screening in Jalisco, Mexico.

● Our data indicate that oportunistic screening on World Kidney Day may be useful for identifying individuals with CKD

" KEEP is an effective CKD screening program for high-risk individuals, an CKD is severely under diagnosed and under recognized.

Conclusions

● CKD and its risk factors are highly prevalent among homeless persons in Jalisco, Mexico. Lack of awareness of having CKD, diabetes, and hypertension is highly common.

● Impaired kidney function, proteinuria, and cardiovascular risk factors are frequently detected when targeting a high-risk population.

● This suggests that trials of case-finding and intervention are feasible and warranted in Mexico and other low income settings.
