Efficacy and feasibility of basal-bolus insulin regimens and a discharge-strategy in hospitalised patients with type 2 diabetes--the HOSMIDIA study.

AIMS: Guidelines recommend use of basal-bolus insulin in hospitalised patients with hyperglycaemia, but information about implementation and medication reconciliation at discharge is scarce. The HOSMIDIA study evaluated a management program involving basal-bolus insulin and an algorithm for medication reconciliation at discharge in non-critically ill hospitalised patients with type 2 diabetes in clinical practice.
METHODS: HOSMIDIA was a prospective, observational study performed during routine clinical practice at 15 Spanish hospitals during hospitalisation, with follow-up 3 months postdischarge. Study patients (n = 134) received a basal-bolus regimen with insulin glargine during hospitalisation and treatment at discharge was adjusted according to a simple algorithm. The control group (n = 62) included patients with similar characteristics hospitalised during the month before study initiation and had no follow-up after discharge.
RESULTS: Compared with control subjects, patients in the prospective study achieved lower mean total (167.7 ± 41.1 vs. 190.5 ± 53.3 mg/dl) preprandial (164.2 ± 42.4 vs. 189.6 ± 52.6 mg/dl; p < 0.001) and fasting (137.0 ± 42.2 vs. 165.8 ± 56.5 mg/dl) blood glucose levels while hospitalised, without increased hypoglycaemic episodes (17.7% vs. 19.3% patients). In the prospective study, glycaemic control improved from admission to discharge, with control maintained 3 months after discharge. The main treatment modification at discharge compared with admission was addition of basal insulin, and treatment at discharge was maintained at 3 months in 89% of patients.
CONCLUSION: The HOSMIDIA study confirmed that management of hyperglycaemia with basal-bolus insulin is feasible and effective in routine clinical practice, and that a simple strategy facilitating the reconciliation of medication on discharge can improve glycaemic control postdischarge.
