Epidemiology and referral patterns of patients with chronic kidney disease in the Emirate of Abu Dhabi

الملخص EN

According to estimates, the dialysis prevalence in Abu Dhabi is around 370 per million population.

The annual growth is 12–15% and the dialysis population is likely to double in the next five years.

Most patients present to dialysis as an emergency and only 2.7% have an arteriovenous fistula at the first dialysis.

The prevalence of chronic kidney disease (CKD) in the Emirate is undefined.

A study of the epidemiology of CKD and referral patterns was undertaken.

SEHA, the Abu Dhabi Health Service delivery company, has a unified computer system containing all measurements made in its laboratories.

This study considered all serum creatinine measurements performed between 1 September 2011 and 31 October 2012 from outpatient departments or emergency rooms.

The estimated glomerular filtration rate (eGRF) was calculated using the Modification of Diet in Renal Disease formula (the Schwartz formula was used for children).

We identified 331,360 samples from 212,314 individuals.

The mean serum creatinine was 61 ± 48 μmol/L in females (59 ± 43 μmol/L in Emiratis, 63 ± 54 μmol/L in expatriates) and 87 ± 69 μmol/L in males (80 ± 59 μmol/L in Emiratis, 92 ± 74 μmol/L in expatriates).

Among Emiratis, 4.6% of males and 2.8% of females had an eGFR between CKD 3 and 5.

Among expatriates, 4.2% of males and 3.2% of females had an eGFR between CKD 3 and 5.

On average, eight months elapsed before a patient with CKD 3, and three months for a patient in CKD 5, to attend the nephrology clinic.

This study has defined the prevalence of CKD within Abu Dhabi and demonstrated the need to improve identification and referral of CKD patients.

Possible solutions include campaigns to increase public and physician awareness of CKD.
