[Factors associated with the optimum simultaneous control of diabetes, arterial hypertension and hypercholesterolemia in the diabetic population. BPC Diabetes study]

OBJECTIVES

To know the degree of simultaneous optimal control of diabetes (DM), high blood pressure (BP) and hypercholesterolemia and determine the associated factors.

MATERIAL AND METHOD

Cross-sectional descriptive study in diabetic patients 18 years aged or older selected consecutively in primary care centers (PC). Patient data were obtained through access to electronical clinical history. Clinical and analytical variables of interest were registered. Good metabolic control was considered as HbA1c < 7%, good blood pressure control (PA) as values < 140/80 mmHg and good LDL cholesterol control (c-LDL) as values < 100 mg/dL. Bivariate analysis was performed and odds ratio were calculated in a logistic regression model. The study was approved by the San Carlos Clinical Hospital's Clinical Research Ethics Committee (CREC), in Madrid.

RESULTS

1420 patients (55.8% male), with an average (SD) age of 70.6 (10.8) years were included. 75.9% were hypertensive patients, and 69.1% dyslipemic. HbA1c values were 6.9 (1.2) %, sistolic BP 135.0 (16.8) mmHg, diastolic BP 75.9 (10.6) mmHg and LDL-cholesterol 93.7 (32.8) mg/dL. Good metabolic control of DM was achieved at 63.0% (95% CI: 60.4-65.5), good control of HTA at 42.6% (95% CI: 40.0-45.2) and good LDL cholesterol control in 61.1% (95% IC: 58.4-63.7) of patients. Good simultaneous control of the three cardiovascular risk factors (CVRF) was reached at 16.1% (95% CI: 14.2-18.1). A positive and independent association (p<0.05) was observed between good simultaneous control of CVRF with age (OR: 1.017) and with personal history of cardiovascular disease (OR: 1.596).

CONCLUSIONS

The results of our study indicate that a small proportion, less than two out of 10 patients, meet the good control goals recommended by clinical practice guidelines. We found important differences between patients with and without cardiovascular disease.

[Analysis of the level of compliance to the clinical practice guidelines recommendations for the diagnosis and monitoring of chronic vascular complications in type2 diabetes in Primary Care]

OBJECTIVE

To evaluate the level of compliance to the clinical practice guidelines (CPG) recommendations for the diagnosis and monitoring of the main chronic vascular complications of patients with type2 diabetes (DM2) in Primary Care (PC).

MATERIAL AND METHODS

A retrospective cross-sectional descriptive study was conducted on patients aged 18years and over and consecutively selected in PC. Patient data were obtained by direct interview and access to the computerised history, and recording the clinical and analytical variables of interest. The determination and recording of urine microalbumin (MALB), glomerular filtration rate (GFR), foot examination (pulse palpation, monofilament or tuning fork), and electrocardiogram (ECG), if performed annually, and the eye fundus (FO) every two years.

RESULTS

A total of 1,420 patients were included, of which 55.8% were male. The mean age (SD) was 70.6 (10.8) years and the mean onset of the diabetes was 9.3 (6.2) years. The mean BMI (kg /m²) was 30.1 (5.4) in females and 29.5 (4.7) in males (P=.023), and a mean HbA1c (%) of 6.9 (1.2). Good metabolic control of DM was achieved in 63.0% (95%CI: 60.4-65.5). In the last two years, 976 (68.7%; 95%CI: 66.2-71.1) patients had an eye fundus examination. The urine microalbumin had been performed on 1,228 patients (86.5%; 95%CI: 84.6-88.2). The mean glomerular filtration rate was performed on 1,391 patients (98.0%; 95%CI: 97.1-98.6), the foot pulses examination on 626 (44.1%; 95%CI: 41.5-46.7), and the neurological examination on 473 patients (33.3%; 95%CI: 30.8-35.8).

CONCLUSIONS

The results of the present study indicate that the presence of retinopathy or neuropathy is not explored in a significant percentage of patients with DM2. Only seven out of ten patients have been screened for retinopathy, one in three had a neurological examination, and only one in four have all the scans recommended by the CPG.

Prevalence of hypotension in hypertensive treated patients within the Primary Care setting. The PRESCAP 2010 study

OBJECTIVE

To determine the prevalence of hypotension and associated factors in hypertensive patients treated in the Primary Care setting.

MATERIALS AND METHODS

A cross-sectional, descriptive, and multicentre study was conducted with a total of 2635 general practitioners consecutively including 12,961 hypertensive patients treated in a Primary Care setting in Spain. An analysis was performed on the variables of age, gender, weight, height, body mass index, waist circumference, cardiovascular risk factors (diabetes, dyslipidaemia, smoking, obesity, sedentary lifestyle), fasting plasma glucose, complete lipid profile, as well as the presence of target organ damage (left ventricular hypertrophy, microalbuminuria, carotid atherosclerosis) and associated clinical conditions. Hypotension was defined as a systolic blood pressure less than 110mmHg or a diastolic blood pressure less than 70mmHg. A multivariate analysis was performed to determine the variables associated with the presence of hypotension.

RESULTS

The mean age was 66.2 years, and 51.7% of patients were women. The mean time of onset of hypertension was 9.1 years. A total of 13.1% of patients (95% confidence interval 12.4-13.6%) had hypotension, 95% of whom had low diastolic blood pressure. The prevalence of hypotension was higher in elderly patients (25.7%) and in those individuals with coronary heart disease (22.6%). The variables associated with the presence of hypotension included a history of cardiovascular disease, being treated with at least 3 antihypertensive drugs, diabetes, and age.

CONCLUSIONS

One out of 4-5 elderly patients, or those with cardiovascular disease, had hypotension. General practitioners should identify these patients in order to determine the causes and adjust treatment to avoid complications.

[Knowledge about Biosimilars in Primary Care: a study by the Spanish Society of Primary Care Physicians (SEMERGEN)]

INTRODUCTION

The objective of this study was to evaluate the awareness and training needs on biosimilar drugs in Primary Care (PC) physicians.

MATERIAL AND METHODS

Descriptive cross-sectional study based on an on-line questionnaire with a total of 34 multiple choice questions, published on the SEMERGEN website. The main Knowledge areas were: biosimilar definition; regulatory and legal framework; prescription, traceability, interchangeability and pharmacovigilance; availability of biosimilars in the PC setting, and the biosimilars contribution to sustainability. The software used for the analysis and data processing was the Barbwin 7.5.

RESULTS

An analysis was performed on the responses from 701 questionnaires completed. There was a slight majority (57%) of women participants. The majority of participant worked in urban centres (60.91%). The definition of biosimilar was not known by 58% of those that responded, and 73% were unaware that the management of biosimilars and generics was not comparable. Most (84%) of those that responded were not aware that the studies required for the approval of biosimilars is different from reference biological medicines. Around two-thirds (66%) those that responded did not know of any biosimilars available in PC setting, and the 94% were also unaware of the Spanish legal framework for the management of biosimilar medicines.

CONCLUSIONS

The current knowledge about biosimilars among PC physicians is low. The critical areas in need of further training include specific information on biosimilars currently available in PC setting, as well as key aspects regarding prescription, interchangeability and pharmacovigilance requirements. Six out of ten doctors do not know of any biosimilar used in PC in Spain.

[Resistant arterial hypertension in Primary Care patients in Spain. PRESCAP Study 2010]

OBJECTIVE

To determine the prevalence and clinical and epidemiological characteristics of Primary Care patients with resistant hypertension (RHT) in Spain.

PATIENTS AND METHODS

A cross-sectional multicenter study was conducted on hypertensive patients aged 18 or over and seen in a Primary Care clinic. RHT was considered as the presence of uncontrolled blood pressure in patients treated with at least 3 drugs, one of which is a diuretic.

RESULTS

Of the 12,961 hypertensive patients in the PRESCAP 2010 study, 962 (7.4%) fulfilled criteria for RHT, of whom 51% were women, and with a mean age (SD) 68.8 [11.4] years. Patients with RHT were older (68.80 [10.69] years vs. 66.06 [11.44] years, P<.001), had a higher prevalence of obesity (55.2 vs. 38.6%, P<.001), a higher waist circumference (103.90 [13.89] vs. 99.32 [13.69] cm, P<.001), and a higher prevalence of DM (48.3 vs. 29.5%, P<.001). The prevalence of target organ damage (73.0 vs. 61.4%, P<.001) and cardiovascular disease (46.7 vs. 26.8%, P<.001) were higher in patients with resistant hypertension. The multivariate analysis showed that the variables associated with resistant hypertension were the presence of cardiovascular disease, diabetes mellitus, sedentary life style, microalbuminuria, body mass index, duration of AHT, and triglycerides.

CONCLUSIONS

The prevalence of RHT in Primary Care patients is related to inappropriate lifestyles, the presence of target organ damage, and cardiovascular disease.

[Evaluation of cardiovascular risk in the cross-sectional phase of the Mediterranean Study]

INTRODUCTION AND OBJECTIVES

The Mediterranean study quantifies high cardiovascular risk (HCR), consistency between REGICOR (R) and low risk SCORE (LS) scales, altered blood pressure (ABP) values in hypercholesterolemia (HC) without any history of hypertension (HT), high total cholesterol (HTC) values with HT with no background of HC and cardiac and renal damage in hypertensive patients.

PATIENTS AND METHODS

A national, cross-sectional and multicenter study was performed with the participation of 751 physicians. The physicians individually evaluated 7,973 patients with HT and 5,319 with HC. HCR was defined as over 10% with R and 5% with LS. Intra-class correlation coefficient (ICC) and Pearson coefficient (r) were calculated. The percentages of ABP and HTC were quantified. Creatinine (cr) value, glomerular filtration rate using Cockroft-Gault (CG), and prevalence of left ventricular hypertrophy (LVH) were analyzed.

RESULTS

Regarding hypertensive patients: 17.3% HCR with R and 26.1% with LS. ICC = 0.222 (p < 0.0001), r = 0.61 (p < 0.0001), 64.7% HTC. There was no evaluation of LVH in 31.2% and a prevalence of 5.1%, prevalence of lesion and kidney failure (KF) of 4.7% and 1.6% respectively based on CR and 15.9% KF by CG. In HC patients, there was 21.1% of HCR with R and 21.5% with LS; ICC = 0.190 (p < 0.0001), r = 0.64 (p < 0.0001) and 33.7% ABP.

CONCLUSIONS

The SCORE scale identifies more patients with HCR than the REGICOR one in HT patients and a similar amount in HC patients. Consistency between both scales is poor. A significant ABP/HTC was found. In HT patients, the patients who were not evaluated for LVH and the percentage of KF are important.
