Purpose: Advancements in pathogen identification by diagnostic testing may improve patient outcomes. This study evaluated healthcare utilization and costs following diagnostic testing for acute oropharyngeal and respiratory tract infections (RTIs). Patients and Methods: Healthcare utilization and costs were evaluated in patients with acute oropharyngeal infections (n=1,172,693), and RTIs (n=4,005,228) who received a syndromic panel-based PCR test with next-day results (HealthTrackRx, Denton, TX), or no test in the IQVIA PharMetrics^® Plus adjudicated claims database. Results: Statistically significant differences were observed between patients who received the PCR test compared to those who received no test. The PCR test cohort had lower total healthcare costs (mean = $5,601±$29,170, median = $807) versus the no test cohort (mean = $7,460±$40,817, median = $1,163) (p = 0.0014) over 6 months, and fewer outpatient visits, other medical service visits, emergency room visits, and inpatient stays (p< 0.0001). Similarly, those who received the PCR test for oropharyngeal infection trended towards lower total healthcare costs (mean = $4,393±$13,524, median=$844) than those who received no test (mean = $5,503±$34,141, median = $956) (p=0.0525) and had fewer outpatient and other medical services (p< 0.0001). Conclusion: Next-day molecular testing for respiratory and oropharyngeal infection lowers healthcare utilization and costs, suggesting improved patient care through reduced need for healthcare resources.

Background/Objectives: Vaginitis is a common infection among women of reproductive age. Although various diagnostic methodologies exist, diagnosis without the utilization of available diagnostic tests remains prevalent. This study aimed to assess downstream healthcare utilization and the cost of patients with and without diagnostic testing. Methods: This retrospective, observational study utilized the IQVIA PharMetrics^® Plus database from July 2020 to October 2023. Patients with an index claim (ICD-10 code indicating vaginitis) were categorized into two cohorts: those who received a syndromic polymerase chain reaction (PCR) test and those who had no documented test on the index date or within two days. Total and service-specific healthcare resource utilization and costs were assessed for 6 months following the index event. This study was designed to inform how Syndromic Vaginitis PCR testing is used to make treatment decisions and to track outpatient and inpatient healthcare utilization for 6 months post index date represented by cost. Results: Patients who received a Syndromic Vaginitis PCR test had significantly fewer outpatient medical services in the 6 months following initial diagnosis compared to those who received no diagnostic test. This was largely attributed to a substantial decrease in other medical service visits, resulting in mean cost savings of USD 2067 (Syndromic PCR = USD 6675, SD = USD 17,187; No Test = USD 8742, SD = USD 29,894) (p-value 0.0009). Conclusions: Many vaginitis patients do not receive testing, but Syndromic Vaginitis PCR testing may be an effective diagnostic tool for reducing costs associated with vaginitis infections.
