INTRODUCTIONChronic kidney disease (CKD) is a major public health problem in Singapore. Efforts are being made to right-site CKD care (stage 1 to 3) from specialist outpatient clinics (SOCs) to general practitioners (GPs) to ease congestion. This study aims to identify factors influencing screening and management of CKD among GPs in Singapore.

MATERIALS AND METHODSA survey was conducted among the 1202 GPs between April and September 2010. The survey questionnaire was developed in collaboration with experts in nephrology and general practice, it included questions about screening, awareness and management of CKD.

POPULATION STUDIEDGPs registered with the National Healthcare Group General Practitioner (NHG GP) partner database.

RESULTSThree hundred and two GPs completed the survey. A total of 70% of the respondents were males and with their median years of practice as 18. A total of 86% of them reported screening for CKD while 50% of GPs were confident of managing patients with CKD stage 1; and 38% of GPs are aware of CKD guidelines. Majority of GPs (64%) agreed that right-siting of early CKD patients would ease congestion at SOCs. Some of the obstacles in CKD management listed by the GPs were lack of patient trust, experience and communication with the specialist and the inability of the patient to pay.

CONCLUSIONGPs screen patients for CKD, however their awareness of guidelines is limited. Opportunities exist for improving physician recognition of CKD, awareness of CKD guidelines, improving collaborative care and reimbursement for the patient and the provider. This study has identified factors which when addressed could lead to wider acceptance of CKD right-siting by both the patients and the GPs.

INTRODUCTIONClinical practice guidelines recommend different blood pressure (BP) goals for chronic kidney disease (CKD) patients. Usage of antihypertensive medication and attainment of BP targets in Asian CKD patients remain unclear. This study describes the profile of antihypertensive agents used and BP components in a multiethnic Asian population with stable CKD.

METHODSStable CKD outpatients with variability of serum creatinine levels < 20%, taken > 3 months apart, were recruited. Mean systolic blood pressure (SBP) and diastolic blood pressure (DBP) were measured using automated manometers, according to practice guidelines. Serum creatinine was assayed and the estimated glomerular filtration rate (GFR) calculated using the CKD Epidemiology Collaboration equation. BP and antihypertensive medication profile was examined using univariate analyses.

RESULTS613 patients (55.1% male; 74.7% Chinese, 6.4% Indian, 11.4% Malay; 35.7% diabetes mellitus) with a mean age of 57.8 ± 14.5 years were recruited. Mean SBP was 139 ± 20 mmHg, DBP was 74 ± 11 mmHg, serum creatinine was 166 ± 115 µmol/L and GFR was 53 ± 32 mL/min/1.73 m(2). At a lower GFR, SBP increased (p < 0.001), whereas DBP decreased (p = 0.0052). Mean SBP increased in tandem with the number of antihypertensive agents used (p < 0.001), while mean DBP decreased when ≥ 3 antihypertensive agents were used (p = 0.0020).

CONCLUSIONDifferent targets are recommended for each BP component in CKD patients. A majority of patients cannot attain SBP targets and/or exceed DBP targets. Research into monitoring and treatment methods is required to better define BP targets in CKD patients.
