Participant Flow

Participants were enrolled into the study when they have a pre-operative encounter for cataract surgery AND the physician starts to order a pre-op lab. Eligible providers were assigned an arm of the study based on their 2019 pre-operative visits. Patients were enrolled into each arm based on the providers arm assignment. Healthcare Providers were not enrolled in the study

Alert 1
Patients with a pre-op encounter in which the physician attempts to place an order for a pre-op test. Physician has been assigned to the Nudge #1 group. Nudge #1: Alert highlighting the safety/potential harms to patients of undergoing pre-op tests: Nudge 1: * UCLA Ophthalmologists and Anesthesiologists ADVISE AGAINST routine pre-op testing. * UCLA Pre-op Eval and Planning Center (PEPC) will order any needed labs on the day of surgery. * Routine pre-op tests are inappropriate. * Routine pre-op tests do NOT increase patient safety and go AGAINST local and national guidelines Hard stop before allowing the ordering of a pre-op test where physicians must provide accountable justification: "EXPLAIN WHY GOING AGAINST GUIDELINES"
Alert 2
Patients with a pre-op encounter in which the physician attempts to place an order for a pre-op test. Physician has been assigned to the Nudge #2 group. Nudge #2: Alert highlighting the financial harms to the patient experiencing pre-op tests: Nudge #2: * UCLA Ophthalmologists and Anesthesiologists ADVISE AGAINST routine pre-op testing. * UCLA Pre-op Eval and Planning Center (PEPC) will order any needed labs on the day of surgery. * Routine pre-op tests are inappropriate. * Routine pre-operative tests can increase the patient's out-of-pocket costs without improving the safety or medical outcomes of cataract surgery and go AGAINST local and national guidelines * Nudge includes "hard stop" before allowing the ordering of a pre-op test where physicians must provide accountable justification: "EXPLAIN WHY GOING AGAINST GUIDELINES"
Alert 3
Patients with a pre-op encounter in which the physician attempts to place an order for a pre-op test. Physician has been assigned to the Nudge #3 group. Nudge #3: Alert highlighting potential psychological harms to the patient of experiencing pre-op tests: Nudge 3: * UCLA Ophthalmologists and Anesthesiologists ADVISE AGAINST routine pre-op testing. * UCLA Pre-op Eval and Planning Center (PEPC) will order any needed labs on the day of surgery. * Routine pre-op tests are inappropriate. * Routine pre-operative tests can cause aggravation and psychological stress for the patient without improving the safety or medical outcomes of cataract surgery and go AGAINST local and national guidelines * Hard stop before allowing the ordering of a pre-op test where physicians must provide accountable justification: "EXPLAIN WHY GOING AGAINST GUIDELINES"
Control
Patients with a pre-op encounter in which the physician attempts to place an order for a pre-op test. Physician has been assigned to the Control group. Encounter continues as usual. Usual Care: Patients will receive usual care from their physicians.
