[Influence of morbidity, metabolic control, and use of resources in subjects with cardiovascular risk in the primary care setting].

OBJECTIVE

To determine the comorbidity, the therapeutic objectives, and economic impact in subjects with cardiovascular risk in primary care (PC).

DESIGN

Multicentre, cross-sectional study.

SETTING

Five urban PC centres, Spain.

PARTICIPANTS

Patients over 55 years seen during the year 2006. Compared according to the presence/absence of a cardiovascular event (CVE).

MEASUREMENTS

Demographics, cardiovascular/general comorbidity (adjusted clinical groups), Charlson index, clinical parameters, multiple drugs and semi-fixed direct costs (operational) and variables (tests, referrals, drugs). A logistical regression and ANCOVA analysis was performed to correct the models. SPSSWIN Program (P< .05).

RESULTS

Of 24 410 patients, 15.4% (CI, 14.9-15.9) had a CVE. The subjects with a CVE showed a higher mortality (4.0% vs 1.8%) and general morbidity (8.1 vs 6.4 episodes) (P< .001). The CVE had an independent association in males (OR=2.7), Charlson index (OR=2.1), dyslipaemia (OR=1.5), depression (OR=1.4), age (OR=1.3), arterial hypertension (OR=1.2) and diabetes (OR=1.1) (P< .005). In primary prevention worse average cholesterols were obtained (211.6 vs 192.4 mg/dL), while in secondary prevention blood glucose was worse (111.3 vs 104.2 mg/dL; P< .001). The average corrected direct costs were euro1543.55 versus euro1027.65, respectively (P< .001). These differences were maintained in all the cost components.

CONCLUSIONS

The presence of a CVE is associated with higher comorbidity, causing an increase in costs. The achievement of therapeutic control objectives could be improved, in primary prevention as well as in secondary. Intervention strategies should be increased to modify life styles in these patients.
