Impact of a clinical pathway on cardiovascular risk in patients with diabetes

Clinical pathways (CPs) are interventions that target the way clinical practice guidelines are applied. They can be implemented in different diseases, including diabetes. In this study we evaluated the impact of the implementation of a CP in the control of cardiovascular risk factors and the occurrence of new events in patients with type 2 diabetes.

A pre- and post-intervention population-based study in a Spanish region, conducted in 2014-2016. Variables before and after the intervention were: screening; good control of diabetes, dyslipidemia and hypertension; hypoglycemia and hyperglycemic decompensation; obesity; cardiovascular events; diabetic ketoacidosis; hyperglycemic and hypoglycemic coma. Proportional differences and parameters of clinical relevance (absolute and relative risk reduction, relative risk and number needed to treat) were calculated.

The CP achieved an improvement in all outcomes, reducing events and increasing control of different cardiovascular parameters. The greatest improvement was in metabolic control (HbA1c) (37.1% in younger patients and 34.0% in older patients) and screening (5.4%). Indicators of clinical relevance showed that the CP was able to improve metabolic control of diabetes with little effort and great benefit.

The CP was of considerable benefit to metabolic control as well as control of dyslipidemia and obesity. Screening for diabetes also benefitted. The CP decreased the incidence of events, especially of angina pectoris.
