Gerencia de Atención Primaria, Madrid310 enrolled

Overview

Pragmatic cluster-randomized clinical trial. An open, multicentric, parallel-group trial with a control group, and with a follow-up period of 1 year.

Pragmatic cluster-randomized clinical trial. An open, multicentric, parallel-group trial with a control group, and with a follow-up period of 1 year. Randomization unit: health care professionals. Analysis unit: patients and health care workers. Scope: primary care (PC) health centers in the Community of Madrid (Spain). Population sample: patients of 40 to 75 years of age with DM2, HbA1c ≥7.5%, on oral antidiabetic drugs (OAD) treatment, who had attended PC consultation during the last year. Sample size: 250 patients (125 per group). Main objective: assess the effectiveness of an intervention based on person-centered interviewing (PCI) to improve metabolic control and increase OAD treatment adherence in patients with DM2. Intervention: four-component intervention including 1) Training of health care professionals (doctors and nurses) on PCI, 2) Practice of PCI techniques, 3) Information card for patients and family members, 4) Instructions sheet on drug prescription. Control arm: usual clinical practice. Variables: 1) Patients: Main: metabolic control (difference of HBA1c ≥0.5%), and OAD treatment adherence (average increase of 50-75%); Secondary: cardiovascular risk, compliance with clinical practice guidelines, complications related to DM2, satisfaction with treatment, adverse effects of medication, usage of health care services. 2) Healthcare workers: professional burnout. Follow-up period: 1 year. Analysis: multi-level models.

Outcomes

Primary Outcomes

Assess the effectiveness of a complex intervention to improve metabolic control of patients with DM2, as measured through decreases in HbA1c values.

Assess the effectiveness of a complex intervention based on person-centered interviewing (PCI), in contrast to usual informational meetings, to improve metabolic control of patients with DM2 that attend PC consultations, as measured through decreases in HbA1c values.

Time frame: 1-year follow-up period

Assess the effectiveness of the intervention to increase adherence to OAD treatment.

Time frame: 1-year follow-up period
