DOAC's

The PAUSE trial (Douketis 2019, see ref) demonstrated the favorable safety and effectiveness of a standardized approach to stopping and then resuming DOAC's around the time of surgery.  To use this protocol, one needs their list of high and low bleeding risk surgeries, and one needs their management protocol table.  Both are linked here.
 
Note that the PAUSE trial was performed on roughly 3,000 atrial fibrillation patients, not on patients with the other indication for DOAC's, VTE prevention and treatment.

High vs Low Bleeding Risk Surgeries list

The PAUSE trial protocol used the following scheme to classify surgeries and procedures as high or low bleeding risk.
 
High Bleed Risk Surgery/Procedures
1) any surgery requiring neuraxial anesthesia
- neuraxial anesthesia/injection
- epidural anesthesia/injection
2) major intracranial or neuraxial surgery
- brain cancer resection
- laminectomy or neuraxial tumour resection
- intracranial (subdural, epidural) bleed evacuation
3) major thoracic surgery
- lobectomy, pneumonectomy
- esophagectomy
4) major cardiac surgery
- coronary artery bypass
- valve replacement or repair
5) major vascular surgery
- aortic aneurysm repair
- aortobifemoral bypass, popliteal bypass
- carotid endarterectomy
6) major abdominopelvic surgery
- hepatobiliary cancer resection
- pancreatic cancer or pseudocyst resection
- colorectal and gastric cancer resection
- diverticular disease resection
- inflammatory bowel disease resection
- renal cancer resection
- bladder cancer resection
- endometrial cancer resection
- ovarian cancer resection
- radical prostatectomy
7) major orthopedic surgery
- hip arthroplasty or hip fracture repair
- knee arthroplasty or tibial osteotomy
- shoulder arthroplasty
- metatarsal osteotomy
8) other major cancer or reconstructive surgery
- head and neck cancer surgery
- reconstructive facial, abdominal, limb surgery
 
Low Bleeding Risk Surgery/Procedures
1) gastrointestinal procedures
- colonoscopy
- gastroscopy
- sigmoidoscopy
- endoscopic retrograde pancreaticocholangiography
- capsule endoscopy
- push enteroscopy
- Barrett’s esophagus ablation
2) cardiac procedures
- permanent pacemaker implantation
- permanent pacemaker battery change
- internal cardiac defibrillator implantation
- internal cardiac defibrillator battery change
- arterioventricular node ablation
- coronary artery angiography (radial approach)
3) dental procedures
- tooth extraction (up to two extractions)
- endodontic (root canal) procedure
4) skin procedures
- skin biopsy
5) eye procedures
- phacoemulsification (cataract)

DOAC Periop Mgmt table (external link)

Below is the explanatory caption for DOAC mgmt table.  The public webpage for the table itself at JAMA oddly does not include the caption, so here it is:
 
No DOAC was taken on certain days (shaded) and on the day of the elective surgery or procedure. The light blue arrows refer to an exception to the basic management, a subgroup of patients taking dabigatran with a creatinine clearance (CrCl) less than 50 ng/mL. The orange arrows refer to patients having a high–bleed-risk surgical procedure. Dark blue arrows refer to patients having a low–bleed-risk surgical procedure. The thickened orange part of arrows refer to flexibility in the timing of DOAC resumption after a procedure.
