The study aims to document the utility of Methodist Charlton Medical Center (MCMC's)Emergency Medicine Pharmacist (EMP) Collaborative Practice Agreement (CPA )utilization for the resolution of outpatient prescription issues. Evaluation of utility will involve describing all EMP-written prescriptions pursuant to resolution of prescription issues realized after discharge.

Use of an EMP CPA, which allows for broad prescriptive authority, will assist Emergency Department (ED )workflow by preventing a significant volume of new prescriptions needing to be sent by physician and mid-level providers. Will improve rates of ED re-visits. In addition, this Collaborative Practice Agreement (CPA) will not be associated with a large volume of new prescription errors.

Inclusion Criteria:

• Patients at MCMC who had a prescription sent by an EMP between November 1, 2021 and June 30, 2023 and a progress note and documenting the reason for the call and action taken by the EMP.

Exclusion Criteria:

• CPA actions were misclassified as discharge prescription issue resolutions.
• Patients with prescriptions pursuant to late culture review, formulation changes not requiring a new prescription, prescription transfers to another pharmacy, or simple retransmission of prescriptions.
• Patients documented to have left the ED against medical advice.
