Hypertension And Surgery Study: Evaluating the Implementation of a Hypertension Guideline Protocol

"Patients with stage 1 hypertension will receive monotherapy and risks of hypotension are negligible. A single antihypertensive lowers blood pressure (BP) on average by 10/5 mmHg.~Patients with stage 2 hypertension will be initiated on two medications and this is recommended by all international hypertension guidelines and studies have shown prompt BP control with minimal side effects.~For borderline patients, the investigators will elect to not treat them for blood pressure ranges of BP: 135-140/85-90 mmHg and give them a letter on discharge to be followed up at their local clinic. The letter will detail that they are potentially hypertensive patients and need to be followed up closely in future.~Patients with Stage 3 hypertension will be referred to the in-hospital physician as per the algorithm."
