The Impact of the COVID-19 Pandemic on Diabetes Management (CoDiaM)

Brief Summary

The "CoDiaM study" examines how diabetes management and outcomes are changing during the COVID-19 pandemic and whether these changes are influenced by socio-demographic factors, health literacy, self-efficacy and perceived social support.

Detailed Description

The Covid-19 pandemic created new challenges for patients with diabetes and their treating physicians. In order to protect people from SARS-COV-2 infections, social contacts were reduced by restrictions on many areas of social life. As a side effect, these measures could have also led to changes in the self-management of patients with diabetes mellitus, such as lack of physical exercise, less healthy dietary behavior, and a reduced intensity of medical care. These possible changes may be associated with poorer control of blood glucose, cholesterol, and blood pressure. Therefore, the CoDiaM study will investigate how management and outcomes of diabetes are changing during the pandemic and identify associated factors. The study is based on data of patients treated in three GP practices specialized on diabetes treatment in Hamburg, Germany. Data collection will include a written patient survey and extraction of clinical data from patient records. The patient's survey includes sociodemographic data and validated instruments to assess diabetes self-management (DSMQ), health literacy (HLS-EU-Q16), self-efficacy (General Self-efficacy scale) and perceived social support (F-SozU K14). Data will be analyzed by descriptive statistics and multivariable, multilevel linear and logistic regression analyses adjusted for possible confounders and random effects on the practice level.
