(I don't know who said this originally, but if you find out, please let me know!)
The sad fact is much of what we do on a day-to-day basis in the practice of medicine is based on very little evidence.
A good source for solid evidence-based resources is the United States Preventative Services Task Force recommendations. You can find or download a set of tools as a part of the:
electronic Preventative Services Selector: ePSS.
Hypertension: Excellent overview
Viewpoint 2017: What is the right target?
Original 2014 Guideline: 2014 Evidence-Based Guideline for the Management of High Blood Pressure in Adults
New Information: Sprint trial

In addition, there are a number of "apps" that I think can be of use in clinic:
1) Agency for Healthcare Research & Quality: electronic Preventive Service Selector (ePSS)
2) Shots by STFM (Society or Teachers of Family Medicine)
3) American Heart Association/American College of Cardiology ASCVD Risk Calculators (online)
