BackgroundA territory-wide diabetes management program (Risk Assessment Management Program – RAMP) was recently established, providing comprehensive management for all diabetics, helping to delineate current level of control and complications prevalence among primary care diabetic patients in Hong Kong.MethodThis cross-sectional study captured anonymous clinical data from RAMP patients. Data obtained include sociodemographic details, type of diabetes, illness duration, family history, drug usage, coexisting illnesses, diabetic complications and other clinical parameters.ResultsData from 15,856 type 2 diabetic patients were analyzed. 57.1% were above 60 years old, with mean disease duration of 7.3 years. Hypertension was the commonest coexisting chronic illness (57.6%). 30.2% and 61.8% have their systolic and diastolic pressure controlled to below 130 mmHg and 80 mmHg respectively. Over half (51.5%) had an HbA1c level of less than 7.0%. 88.4% did not achieve target lipid level. 15% were on diet control alone. Only 22.2% were on statins. In patients with microalbuminuria and macroalbuminuria, 40.7% and 54.5% were on angiotensin converting enzyme inhibitor (ACEI) or angiotensin receptor blocker (ARB) respectively. 12.9%, 38.8% and 2.4% had diabetic retinopathy, nephropathy and neuropathy respectively. Overall, 37.9%, 7.3% and 0.4% had single, two and three concurrent microvascular complications respectively.ConclusionThe level of diabetic control is comparable with other developed countries. We demonstrated a high prevalence of microvascular complications among Chinese primary care patients despite achieving adequate HbA1c levels, highlighting the importance of managing all aspects of diabetes including weight, lipid and blood pressure. Efforts to improve holistic management must be tailored according to the needs of our population, with the challenges that the majority have low educational background and in the older age group.

Background Many foreign studies investigated glycemic control and fall risk. However, there was insufficient study on this topic in Hong Kong. This study aims to find out the association of glycemic control and fall risk in the diabetic elderly in a general outpatient clinic in the North District of Hong Kong. Their frequency of falls and other associated risk factors of fall were also studied. Methods A cross-sectional questionnaire survey was conducted on 442 diabetic patients aged 65 years-old or above with regular follow-up in a general outpatient clinic. Main outcome measure was the number of falls in the past one year from the interview date. Recurrent falls was defined as two or more falls in the past one year from the interview date. Subjects were asked about experience of hypoglycemic symptoms. HbA1c level, chronic illness, retinopathy etc. were obtained through computerized medical record review. Chi square test and logistic regression were used to assess the association between outcomes and the explanatory variables. Results In the past one year, 23.3% participants experienced at least one fall and 8.6% had recurrent falls. Hypoglycemic symptoms, and lower visual acuity < 0.6 were significantly associated with fall (OR 2.42, p = 0.007 and OR 1.75, p = 0.038 respectively). Age 75–79 years-old had a higher likelihood of fall than the 65–69 age group (OR 2.23, p = 0.044). Patients with HbA1c 7.0–7.4% had a lower risk of recurrent falls when compared to those with intensive control (OR 0.32, p = 0.044). Other risk factors that increased risk of recurrent falls were hypoglycemic symptoms (OR 6.64, p < 0.001) and history of cerebral vascular accident (OR 4.24, p = 0.003). Conclusions Hypoglycemic symptoms had a very strong association with falls. Less stringent HbA1c control reduced the risk of recurrent falls. Healthcare professionals need to take a more proactive approach in enquiring about hypoglycemia. There should be individualized diabetic treatment target for the diabetic elderly.

Background Hypertension is strongly associated with cardiovascular events. Studies have shown that electrocardiographic (ECG) abnormalities were associated with increased risks for cardiovascular events. However local data is limited. The objectives of this study were: (1) to determine the prevalence of major electrocardiographic abnormalities in patients with hypertension in primary care in Hong Kong, and (2) to determine the association of major electrocardiographic abnormalities with patients’ socio-economical background, cardiovascular disease and cardiovascular risk factors. Methods This was a cross-sectional study. Subjects were hypertensive patients aged between 18 and 80 who were enrolled in the Risk Assessment and Management Programme (RAMP) in a general outpatient clinic in Hong Kong. Outcome measures were prevalence of probable ischaemic heart disease (IHD), complete left bundle branch block (LBBB), left ventricular hypertrophy (LVH) and atrial fibrillation (AF) in patients with hypertension. The Pearson Chi-square test, independent t-test and Mantel–Haenszel test were used to measure the association between socioeconomic characteristics and cardiovascular risk factors, and ECG abnormalities. Results 504 hypertensive patients aged 18–80 were recruited in a general outpatient clinic. 6.3% had probable IHD, 0.4% had complete LBBB, 4.0% had LVH and 1.0% had AF. Probable IHD was associated with smoking (P = 0.032), hypercholesterolaemia (P = 0.037) and higher 10-year CV risk (P = 0.04). Complete LBBB was associated with smoking (P = 0.021) and hypercholesterolaemia (P = 0.022). LVH was associated with male gender (P = 0.001) and longer duration of hypertension (P = 0.035). AF was not significantly associated with any of the clinical or sociodemographic parameters. Conclusions This study showed that a significant proportion of patients with hypertension at the primary care setting in Hong Kong had probable ischaemic heart disease, left ventricular hypertrophy and atrial fibrillation. This finding is consistent with both overseas data and historic data in Hong Kong. The detection of electrocardiographic abnormalities is helpful in hypertension management by improving risk stratification.
