Diabetes is often poorly managed in hospitals. This study assessed the level of adherence to current Canadian practice guidelines for inpatient pharmacologic management of type 2 diabetes and whether it affected the frequency of hyperglycemia or hypoglycemia. ⋯ Adherence to guidelines for inpatient type 2 diabetes management is good and may be greater with more training. Hyperglycemia was more common in patients who did not receive guideline-based care. Hypoglycemia was uncommon and did not appear to be more common in the guideline-adherent group, although numbers were small. These results may alleviate physicians' fear that providing adequate insulin to hospitalized patients may cause hypoglycemia.

The renin angiotensin aldosterone system (RAAS) plays a central role in the pathophysiology of hypertension and vascular disease. Angiotensin-converting enzyme inhibitors (ACEi's) suppress angiotensin II (ANG II) concentrations, whereas angiotensin II type 1 (AT1) receptor blockers (ARBs) block the binding of ANG II to AT1 receptors. ACEi's and ARBs are both effective antihypertensive agents and produce similar risk reductions for stroke, a blood pressure-dependent phenomenon. ⋯ Systematic reviews of ARBs that include meta-analyses or metaregression analyses confirm that ARBs lack the cardiovascular-protective effects of ACEi's. Practice guidelines, especially those for high-risk patients, such as those with diabetes mellitus, should reflect the evidence that ACEi's and ARBs have divergent cardiovascular effects: ACEi's reduce mortality, whereas ARBs do not. ACEi's should remain the preferred RAAS inhibitor for patients at high risk.
