Intervention Details:
  • Other: Epidemiological intervention
    An analysis of 600 diabetic patients in the Island of PR to evaluate metabolic control.

Primary Outcome Measures :
  1. Blood sugar control [ Time Frame: 2 years ]
    Numbers of Patients with Hg A1C on control (less than 7%). Those with A1c greater than 7% will be considered as not meeting the goal

  2. Blood pressure control [ Time Frame: 2 years ]
    Blood Pressure Control: Patients will be considered out of blood pressure control if they have a systolic blood pressure greater than 130 mm Hg or a diastolic blood pressure greater than 80 mg Hg

  3. Lipids goal achievement [ Time Frame: 2 years ]
    The following lipids results will be considered out of goal for this population: LDL cholesterol greater than 100 mg/dL, HDL cholestero lower than 40 mg/dL in male and lower than 50 mg/dL in women, and serum triglycerides greater than 150 mg/dL

Secondary Outcome Measures :
  1. Achievement of National Clinical Practice Recommendations among Puerto Rican Population with Diabetes Mellitus [ Time Frame: 2 years ]
    Type of therapies used by these populations and their relationship with out of goals outcome.

Other Outcome Measures:
  1. Achievement of National Clinical Practice Recommendations among Puerto Rican Population with Diabetes Mellitus [ Time Frame: 1 year ]

    Outcome measure assessment: Descriptive analysis will be computed to describe the demographic and health services characteristic of the participants.

    Bivariate analysis using contingency tables and the Pearson Chi-square test and independent samples t-tests will be conducted to determine whether or not there were differences between adults with diabetes and A1C levels lower than 7% and those with A1C levels greater than 7% in term of demographics, health services characteristics, health insurance type, type of providers, type of medication (insulin or pills) and comorbidities. For statistical analysis, alpha will be set at p < 0.05.
