Hypoglycemic Risk Factors Among Hospitalized Patients with Type 2 Diabetes Mellitus at King Abdulaziz Medical City, Jeddah

摘要

Background Hypoglycemia is a pathological condition in which the?serum?glucose level measures less than 3.0 mmol/L. It is a well-known complication in patients with diabetes mellitus. Age, body weight, gender, insulin usage, nutritional therapy, body mass index (BMI), the presence of diabetes complications, intensive care unit admission, and infection were reported as possible risk factors that?may increase the risk of hypoglycemia. Therefore, this study aimed to analyze?predisposing factors?for hypoglycemia among hospitalized patients with type 2 diabetes in King Abdulaziz Medical City. Method This is a retrospective, case-control study design. The study included 326 hospitalized patients with type 2 diabetes; 152 experienced hypoglycemia (blood glucose 3.9) at least once during hospitalization and have been compared to 174 in the non-hypoglycemic group (blood glucose ≥3.9). Data were extracted from their electronic medical records (EMRs). Results This study reported that patients with lower BMI (28.80 ± 7 versus 31.20 ± 12.93) experienced hypoglycemia (P-value 0.044). Those hospitalized with infections or had acquired infections or required intensive care unit (ICU) admission during hospitalization had a higher risk to develop hypoglycemia (P-value 0.005, 0.003, and 0.001, respectively). Moreover, the use of multiple doses of insulin therapy or basal-plus insulin therapy?was associated with a higher risk of hypoglycemia?(P-value 0.012 and 0.028, respectively). Those on supplemental insulin were less likely to develop hypoglycemia (P-value 0.001). Patients on oral feeding had a lower chance of having a hypoglycemic attack (P-value 0.002) while those on tube feeding had double the odds (OR=2.37). Conclusions Infection, intensive care unit admission, lower body mass index, insulin regimen and nutritional therapy (enteral feeding and nothing-per-mouth (NPO))?were correlated with an elevated risk of having hypoglycemia in?hospitalized patients with type 2 diabetes mellitus.
