Given the risks associated with direct oral anticoagulants (DOACs) and the lack of defined pathways for patients prescribed this class of medications, the study intervention has the potential for an enormous impact in preventing medication errors and improving the quality of care transition, patient knowledge, and adherence with DOAC therapy.
Patients first treated with direct oral anticoagulants (DOACs) in an ambulatory setting are at an elevated risk for adverse drug events (ADEs) or potential ADEs from medication errors. An intervention that integrates clinical pharmacists, a pharmacy technician, and follows a checklist published by experts at the Anticoagulation Forum can prevent adverse outcomes. The Investigators propose research on the effectiveness, implementation, and dissemination for a care transition intervention that follows the checklist which includes evaluation for appropriateness of DOAC use, assistance with drug procurement, telephone access to an anticoagulation expert, and other best practice recommendations.

After randomization, the pharmacist calls patients to assess drug choice and dose. Staff distribute manufacturer coupons and help patients apply for medication payment assistance. Pharmacist discusses DOAC alternatives with prescribe and provides DOAC education by discussing potential adverse effects, medication interactions, alarm symptoms, and lab work. Staff mail educational materials. Pharmacist documents concerns in the electronic health record and messages prescriber about missing lab work. Patients share medication-related concerns. Patients are provided with a phone number for non-education calls to discuss their medications from 6 AM - 10 PM on any day. The pharmacist offers dose de-escalation instructions based on the DOAC prescription. The pharmacist advises the continuity provider on DOAC duration and monitoring. For follow-up/perioperative support, the pharmacist reviews and recommends lab monitoring and gives DOAC interruption/resumption recommendations.

Number of Direct Oral Anticoagulant (DOAC)-Related Clinically Important Medication Errors
The number of preventable, ameliorable and potential Adverse Drug Events (ADEs) that physician reviewers attribute to Direct Oral Anticoagulant (DOAC) medication. Each DOAC related clinically important medication error is counted as a separate event, enabling patients to have multiple events consistent with the literature.
Time frame: 90 Days Post Enrollment
Patient Knowledge regarding Anticoagulation and Venus Thromboembolism (VTE) using the Anticoagulation and Venus Thromboembolism (VTE) knowledge questionnaire
Patient knowledge regarding Anticoagulation and Venus Thromboembolism (VTE) will be evaluated using a modified version of a 22-item instrument previously developed and tested by the institution. This instrument assesses patients' knowledge of warning signs of bleeding and new VTE, interactions with other medications, and complications of VTE. A low score indicate a low level of knowledge and a high score indicates a high level of knowledge regarding anticoagulation and VTE.
Time frame: 90 Days Post Enrollment
Number of missed or extra doses to assess medication adherence
Patients are asked to to count out the number of remaining pills from the last filled prescription and provide the fill date, number of pills dispensed, the schedule prescribed (either once or twice a day depending on DOAC), and skipped doses for deliberate interruption to determine medication adherence with the number of missed or extra doses.
Time frame: 90 Days Post Enrollment
Medication Possession Ratio (MPR) to assess medication adherence
Medication adherence is measured with Medication Possession Ratio (MPR) which is the ratio between the time a patient had medication on hand, the time that a patient is eligible to have a medication on hand, and the time that a patient is covered by the medication. The MPR ratio will be calculated by using available pharmacy data.

Proportion of days covered (PDC) to assess medication adherence
Proportion of Days Covered (PDC) is the ratio between the time that a patient has a medication on hand, the time that a patient is eligible to have a medication on hand, and the time that a patient is covered by the medication. Medication adherence will be evaluated using the mean PDC using available pharmacy data.
