ABSTRACT

Objective:

To determine the influence of number and type of antidiabetes medications on adherence and glycemia of ambulatory type 2 diabetes patients in southwestern Nigeria.

Methods:

A cross-sectional study using pre-tested structured questionnaire among 176 consented patients recruited from the endocrinology clinics of two teaching hospitals between November, 2010 and January, 2011; and a retrospective review of case notes of the cohort for details of prescribed medications and blood glucose values. Descriptive statistics were used to summarize the data. Tests of proportions were evaluated using Chi-square or Fisher’s exact test as appropriate. The differences in mean fasting blood glucose (FBG) between and among categorical variables were compared using student t-test and ANOVA respectively, with p<0.05 considered significant.

Results:

Mean number of prescribed medications was 4.6±1.4. Almost two thirds 103 (60.6%) were placed on >4 medications. Adherence was better among patients on >4 medications compared to those on ≤4 medications (p=0.05). However, patients on >4 medications were mostly older adults (>60 years of age), and they were in the majority (66.7%) who had tertiary education compared to 33.3% of those on <=4 medications who had tertiary education (p=0.02). Adherence rates to antidiabetes medications were in the ranking of oral antidiabetes medications (OAM) alone (50.0%) > insulin plus OAM (44.0%) > insulin alone (41.7%) with no significant difference (p=0.77). There was a significant difference in mean FBG among patients on >4 medications (172.1 ±61.1mg/dL) versus (198.8 ±83.8mg/dL) among those on <=4 medications (p=0.02).

Conclusion:

Prescribing more than four medications is linked to improved adherence and glycemic outcome. However, age and educational background of patients are important factors that need to be considered when prescribing multiple medications for type 2 diabetes (AU)
RESUMEN

Objetivo:

Determinarla influencia del número y tipo de medicamentos antidiabéticos en la adherencia y la glucemia de pacientes con diabetes tipo 2 en el suroeste de Nigeria.

Métodos:

Estudio transversal utilizando un cuestionario pre-estructurado en 176 pacientes que aceptaron, reclutados en la clínica de endocrinología de dos hospitales Universitarios entre noviembre 2010 y enero 2011; y revisión retrospectiva de las notas clínicas de la cohorte para recopilar los detalles de medicamentos prescritos y valores de glucemia. Se utilizó estadística descriptiva para presentar los datos. Las proporciones se analizaron usando test chicuadrado o pruebas exactas de Fischer cuando fue apropiado. La diferencia entre las medias de glucemia en ayuno (FBG) se compararon usando ttest y ANOVA, considerando significativos p<0,05.

Resultados:

La media de medicamentos prescritos fue de 4,6±1,4. Casi dos tercios, 103 (60,6%), tenían >4 medicamentos. La adherencia era mejor entre los pacientes con >4 medicamentos comparados con los de ≤4 medicamentos (p=0,05). Sin embargo, los pacientes con >4 medicamentos eran mayoritariamente adultos mayores (>60 años) y en su mayoría (66,7%) tenían educación terciaria, comparado con el 33,3% de los de <=4 medicamentos con educación terciaria (p=0,02). Las tasas de adherencia a medicamentos antidiabéticos estaban en el margen de los antidiabéticos orales solos (AOS) (50,0%) > insulina más AOS (44,0%) > insulina sola (41,7%) sin diferencias significativas p=0,77). Hubo diferencia significativa en la FBG entre los pacientes con >4 medicamentos contra los de <= (172.1±61.1mg/dL vs. 198.8±83.8mg/dL, respectivamente. p=0,02).

Conclusión:

Prescribir más de cuatro medicamentos está asociado con una mejoría de la adherencia y de resultados de la glucemia. Sin embargo, la edad y la escolaridad son factores importantes que deben considerarse cuando se prescriben medicamentos para la diabetes tipo 2 (AU)
