Metabolic parameters and blood pressures achieved by diabetic patients at two health care facilities in south Trinidad

Background: Previous studies have demonstrated poor metabolic and blood pressure control in the diabetic population in Trinidad. The aim of this study is to compare baseline and follow-up metabolic parameters and blood pressures taken within a 16-month period to ascertain if there have been improvements. Method: A retrospective chart review was conducted of diabetic patients at the Siparia and Erin health facilities in 2012. To be eligible, charts had to contain two point-of-care values of HbA1c, Total Cholesterol (TC), Triglycerides (TG), Low Density Lipoproteins (LDL), systolic and diastolic blood pressure (BP), and weight measurements taken within a 16-month period with at least an 8-month interval from the initial to the final testing. Comparisons were made with the Caribbean Health Research Council (CHRC) guidelines to determine clinical significance. Results: 253 patients from Siparia and 68 from Erin were studied. At Siparia there was a statistically significant change in TG, LDL and diastolic BP, with TG levels actually worsening (p < 0.05). At Erin there was a statistically significant change in HbA1c, LDL and diastolic BP. At neither site did these changes achieve clinical significance. There were statistically significant differences between the means of HbA1c and systolic BP by age, but not by gender or ethnicity. On comparing the outcomes between the two health facilities, there were no statistically significant differences between them. When compared with the recommendations by the CHRC, only for the TC was the guideline level achieved. Conclusion: Despite heavy investment in primary care centers, there continues to be little success in achieving metabolic and BP control for diabetic patients in Trinidad.
