ABSTRACT

Hypertension Canada provides annually updated, evidence-based guidelines for the diagnosis, assessment, prevention, and treatment of hypertension. This year, we introduce 10 new guidelines. Three previous guidelines have been revised and 5 have been removed. Previous age and frailty distinctions have been removed as considerations for when to initiate antihypertensive therapy. In the presence of macrovascular target organ damage, or in those with independent cardiovascular risk factors, antihypertensive therapy should be considered for all individuals with elevated average systolic nonautomated office blood pressure (non-AOBP) readings ≥ 140 mm Hg. For individuals with diastolic hypertension (with or without systolic hypertension), fixed-dose single-pill combinations are now recommended as an initial treatment option. Preference is given to pills containing an angiotensin-converting enzyme inhibitor or angiotensin receptor blocker in combination with either a calcium channel blocker or diuretic. Whenever a diuretic is selected as monotherapy, longer-acting agents are preferred. In patients with established ischemic heart disease, caution should be exercised in lowering diastolic non-AOBP to ≤ 60 mm Hg, especially in the presence of left ventricular hypertrophy. After a hemorrhagic stroke, in the first 24 hours, systolic non-AOBP lowering to < 140 mm Hg is not recommended. Finally, guidance is now provided for screening, initial diagnosis, assessment, and treatment of renovascular hypertension arising from fibromuscular dysplasia. The specific evidence and rationale underlying each of these guidelines are discussed.

ABSTRACT

OBJECTIVE: We sought to determine whether the implementation of a sepsis protocol in a Canadian emergency department (ED) improves care for the subset of patients admitted to the intensive care unit (ICU). METHODS: After implementing a sepsis protocol in our ED we used an ICU database and chart review to compare various time-dependent end points and outcomes between a historical control year and the first year after implementation. We re-viewed the charts of all patients admitted to the ICU within 24 hours of ED admission with a primary or other diagnosis of sepsis, severe sepsis or septic shock, who met criteria for early goal-directed therapy within the first 6 hours of their ED stay. RESULTS: We compared 29 patients from the control year with 30 patients from the year after implementation of our sepsis protocol. We found that patients treated during the postintervention year had improvements in time to antibiotics (4.2 v. 1.0 h, difference = -3.2 h, 95% CI -4.8 to -2.0), time to central line placement (above the diaphragm) (11.6 v. 3.2 h, difference = -8.4 h, 95% CI -12.1 to -4.7), time to arterial line placement (7.5 v. 2.3 h, difference = -5.2 h, 95% CI -7.4 to -3.0), and achievement of central venous pressure and central venous oxygen saturation goals (11.1 v. 5.1 h, difference = -6.0 h, 95% CI -11.03 to -1.71, and 13.1 v. 5.5 h, difference = -7.6 h, 95% CI -11.97 to -3.16, respectively). There were no statistically significant differences in ICU length of stay, hospital length of stay or mortality (31.0% v. 20.0%, difference = -11.0%, 95% -33.1% to 11.1%). CONCLUSION: Implementation of an ED sepsis protocol im-proves care for patients with severe sepsis and septic shock.
