Abstract Background Outpatient parenteral antimicrobial therapy (OPAT) allows patients to complete extended antimicrobial treatment at home, improving quality of life and reducing healthcare costs. National guidelines outline best practices for antimicrobial administration, vascular access management, monitoring, and recommend involving an infectious disease physician and a multidisciplinary team. Evaluating adherence to these practices can identify improvement opportunities and enhance outcomes. The primary objective of this study was to assess patient outcomes related to adherence to OPAT best practices at Mayo Clinic Health System – Southwest Wisconsin (MCHS–SWWI). Secondary objectives included evaluating adherence to key process metrics and identifying associations between baseline characteristics and outcomes. Methods This retrospective cohort study included adults discharged from MCHS–SWWI on home OPAT from November 2021 to July 2024. Patients were excluded if under 18 years old or if they received OPAT in non-home settings (e.g., skilled nursing, infusion center). Data on process metrics, outcomes, and safety were collected through manual chart review. These findings were evaluated against established best practices to assess the OPAT program's adherence and determine the impact of this adherence on patient outcomes. Statistical analysis used Pearson’s chi-square tests and Wilcoxon rank sum tests to measure associations of patient characteristics with outcomes. Results A total of 164 patients were included. The MCHS-SWWI OPAT program demonstrated high adherence ( > 85%) to majority of established best practices. Successful OPAT completion occurred in 92.7% of patients, and overall incidence of adverse events and poor outcomes was generally low. Adherence to best practices was below 85% for vascular access selection (81.7%) and completion of weekly labs and vascular access care throughout the OPAT course (∼69%). Conclusion High adherence to OPAT best practices led to a generally low incidence of adverse events, treatment failures, and other unfavorable patient outcomes. The results of this study provide valuable insights to guide institutional quality improvement initiatives aimed at optimizing patient outcomes in OPAT therapy through targeted interventions.

Background: Recent literature demonstrated a 24-hour reduction in vancomycin duration of therapy (DOT) for skin and soft tissue infections (SSTIs) with a negative methicillin-resistant staphylococcus aureus (MRSA) nasal screening versus a positive nasal screening. Objective of this study was to investigate vancomycin DOT in patients with SSTIs who received MRSA nasal polymerase chain reaction (PCR) screening versus those who did not receive MRSA nasal PCR screening. Methods: A retrospective, multi-center, cohort study was completed in admitted adult patients on vancomycin for SSTI from 01/01/2020 to 09/30/2022. Hospital policy permits any clinician to order a MRSA nasal PCR screening test for various indications, including SSTIs, pneumonia and sepsis. Results: One-hundred-fifty-one patients were included, of which 71 had MRSA nasal PCR screening tests obtained, and 80 did not. The median vancomycin DOT in patients with MRSA nasal PCR screening tests was 19.9 versus 36.7 hours ( P = .014) in patients without screening tests. Conclusion: Patients with SSTIs who receive MRSA nasal PCR screening tests have a shortened vancomycin DOT. These results contribute to current data in support of the efficacy and clinical utility of obtaining MRSA nasal PCR screening tests for SSTIs.

Background Sexual assault survivors are at increased risk for sexually transmitted infections. Sexual Assault Nurse Examiner programs guide sexually transmitted infection treatment, monitoring, and follow-up scheduling according to guidelines by the Centers for Disease Control and Prevention (CDC). Reported low rates of provider adherence to CDC treatment guidelines and patient adherence to follow-up necessitate a review of medication prescribing and follow-up scheduling practices, especially at smaller community hospitals in the United States. Methods A retrospective medical record review was conducted to assess adherence rates to CDC guidelines for prescribing practices, scheduling, and follow-up of sexual assault survivors. We included pediatric and adult patients presenting to the emergency department (ED) and participating in the ED Sexual Assault Nurse Examiner program at a rural, community-based teaching hospital in La Crosse, WI, from January 2018 to December 2021. Descriptive statistics were used to evaluate results. Results Analysis included 103 patients. Prescribing adherence to CDC guidelines was >80% for all except human immunodeficiency virus (53.4%), trichomoniasis (68.1%), and hepatitis B (69%). Of the 38 patients who had a follow-up scheduled during their ED encounter, 78.9% attended their scheduled follow-up and 94.7% of those appointments were scheduled within the CDC-recommended time frame, leading to an overall adherence of 40%. Conclusions Adherence rates were high for most prescribing practices, and attendance of scheduled follow-up was higher than expected. Opportunities to improved adherence to CDC guidelines were identified in prescribing for 3 disease states (human immunodeficiency virus, trichomoniasis, and hepatitis B) and in scheduling of follow-up.

Abstract Background Sexual assault survivors are at increased risk for sexually transmitted infections. Due to patient vulnerability, institutions have implemented Sexual Assault Nurse Examiner (SANE) protocols to care for these patients. These protocols guide evidence collection, testing, treatment, and medical follow-up to ensure optimization of sexually transmitted infections (STIs) treatment, monitoring and follow-up. Previous gap analyses have identified decreased prescribing of prophylactic STI medications and scheduling follow-up appointments compared to guideline recommendations. The purpose of this study was to assess adherence of medication prescribing and follow-up scheduling practices to Centers for Disease Control (CDC) guidelines. Methods This study was a single-center, retrospective, observational, descriptive assessment which evaluated adherence rates to CDC guidelines, to scheduling medical follow-up, and patient attendance at scheduled appointments. Pediatric and adult patients who presented to the emergency department at Mayo Clinic Health System in La Crosse, WI from January 2018 through December 2021 were included. Data collected through chart review included demographics and laboratory data necessary for prescribing prophylactic HIV medications, antibiotics for STIs, emergency contraception, and vaccine administration. Descriptive statistics were used to evaluate results. Results One hundred three patients were evaluated. Majority of patients were female and presented within 3 days of assault. Medication adherence to CDC guidelines was ≥ 80% for chlamydia and gonorrhea whereas < 80% was noted for trichomoniasis and HIV prophylaxis. Adherence to post-ED discharge follow-up was 40%. Conclusion Opportunities to improve adherence of ED-SANE protocols for medication prescribing and medical follow-up for trichomoniasis and HIV prophylaxis exist.
