Psychiatric referral and glycemic control of Egyptian type 2 diabetes mellitus patients with depression.

OBJECTIVE: To evaluate the relationship between psychiatric referral acceptance for fluoxetine treatment and glycemic control in type 2 diabetes mellitus (T2DM) Egyptian patients with depression.

METHODS: Patients with T2DM who attended the diabetes outpatients clinic at Zagazig University Hospital, Egypt, between May 2013 and April 2015 and who scored ≥20 on screening with the Major Depression Inventory (MDI) (n=196) were offered a psychiatric referral for fluoxetine treatment and monitoring. Decliners (56.1%) received time/attention matched care via diabetologist visits (attentional controls). Fluoxetine patients and controls were compared at the time of the offer (T1) and 8weeks later (T2). Factors that significantly correlated with glycemic control were used in a linear regression analysis as the independent variables.

RESULTS: Eighty-six patients (43.9%) accepted psychiatric referral. Most of them (97.7%) remained throughout the study adherent to fluoxetine (mean daily dose=31.9mg). At T2, these patients, in comparison to controls, showed a reduction from baseline in MDI, fasting plasma glucose and glycosylated hemoglobin (HbA1c) levels (P for all comparisons <.001). In the final model of a regression analysis, 65.9% of the variation in percentage change in HbA1c was explained by adherence to antidiabetics, psychiatric referral acceptance and Internalized Stigma of Mental Illness (ISMI) and MDI scores.

CONCLUSION: In T2DM patients with depression, psychiatric referral acceptance for fluoxetine treatment is a significant predictor of both depression and glycemic control improvements.
