Change of glycaemic control and predictors in diabetes patients: Longitudinal observational study during the one year after hospital discharge

Effect of follow-up by a hospital diabetes care team on diabetes control at one year after discharge from the hospital

AIM

This study was conducted to evaluate the effect of continued follow-up by a hospital diabetes team on HbA1c at 1-year after discharge.

METHODS

Adults with HbA1c ≥8% (64mmol/mol), undergoing an elective surgery, were treated in the perioperative period and randomized to continued care (CC) or the usual care (UC) after discharge. Patients in the CC group received weekly to monthly phone calls from a diabetes specialist nurse practitioner (NP) to review their home blood glucose values, diet, exercise, and medications. Patients in the UC group followed with their diabetes care providers.

RESULTS

Out of 151 patients, 77 were randomized to the CC group and 74 to the UC group. HbA1c (%) at 1-year was 8.2±1.4 in the CC group and 8.5±1.5 in the UC group (p=NS). Change in HbA1c from baseline was similar between the groups; -0.7±1.4 in the CC versus -0.7±1.5 in the UC group (p=NS). A higher number of calls was not associated with lower HbA1c or reduction in HbA1c. There were 41 insulin-treated patients in the CC group and 53 in the UC group and among them, HbA1c reduction was 0.5±1.5 and 0.6±1.3 respectively (p=NS).

CONCLUSIONS

Optimal perioperative treatment of diabetes is associated with an improvement in HbA1c but continued follow-up by a hospital diabetes team after discharge does not have an additional impact on long-term glycemic control. ClinicalTrials.gov identifier NCT02065050.

Socioeconomic status and glycemic control in adult patients with type 2 diabetes: a mediation analysis

OBJECTIVE

The purpose of this study is to examine the contribution of health behaviors (self-management and coping), quality of care, and individual characteristics (depressive symptoms, self-efficacy, illness representations) as mediators in the relationship between socioeconomic status (SES) and glycemic control.

METHODS

A sample of 295 adult patients with type 2 diabetes was recruited at the end of a diabetes education course. Glycemic control was evaluated through glycosylated hemoglobin (HbA1c). Living in poverty and education level were used as indicators of SES.

RESULTS

Bootstrapping analysis showed that the significant effects of poverty and education level on HbA1c were mediated by avoidance coping and depressive symptoms. The representation that diabetes is unpredictable significantly mediated the relationship between living in poverty and HbA1c, while healthy diet mediated the relationship between education level and HbA1c.

CONCLUSIONS

To improve glycemic control among patients with low SES, professionals should regularly screen for depression, offering treatment when needed, and pay attention to patients' illness representations and coping strategies for handling stress related to their chronic disease. They should also support patients in improving their self-management skills for a healthy diet.
