This is a descriptive study that uses data from health service claims for patients with type 2 diabetes (T2DM) from public and private insurers operating in Puerto Rico during 2013, with the objective of estimating the prevalence of comorbidities in this population. Descriptive analyses were performed according to sociodemographic variables and type of service, using frequencies and percentages for categorical data, and averages (+/- DE) or medians (RIC) for continuous variables. Chi-square, Fisher's exact or independent sample t-tests were used for comparisons. A total of 3,100,636 complaints were identified for 485,866 adult patients with T2DM. 48% of the studied population was over 65 years old. The majority were women (57%) and had private insurance (77%). The Metropolitan Area (17%) and Caguas (16%) regions reported the highest number of people with T2DM. The estimated global prevalence of T2DM was 17.4%. The number of complaints per patient ranged from 1 to 339, with an average of 6.3 claims (DE±9.99) and a median of 3 (Q1 1 - Q3 8). Of the total number of complaints, the majority (74%) were related to the diagnosis of diabetes (59%) and related to outpatient services (88%). The most common comorbidities were hypertension (48%), hyperlipidemia (41%), neuropathy (21%), kidney disease (15%) and retinopathy (13%). There was evidence of a high prevalence and co-prevalence of comorbidities, as well as an intense use of health services, especially in older adults with T2DM. Since most comorbidities are the consequence of conditions associated with diabetes, this analysis highlights the importance of early diagnosis and appropriate management to avoid preventable burdens for both the patient and the healthcare system.
