Assessment of the Process of Initial Antibiotic Therapy for Patients with Sepsis in the Emergency Department of a Tertiary Hospital in the Philippines: A Mixed Methodology.

Background: Sepsis is a life-threatening organ dysfunction in response to an infection, and immediate administration of the first antibiotic dose, along with other resuscitative efforts, improves patient outcomes. This paved the way for the development of evidence-based sepsis pathways in different health institutions. Objectives: This study aims to assess the process of initial antibiotic therapy, from the time the loading dose of antibiotic was ordered to the time it was administered, for adult patients with sepsis admitted at the Emergency Department (ED) of the University of the Philippines - Philippine General Hospital (UP-PGH). Methods: In phase 1 of the study, a review of medical records was done to identify all adult patients diagnosed with sepsis in the ED from February 1 to August 31, 2022. A variant of time-motion analysis was used wherein three points in the sepsis pathway were identified: the time of diagnosis of sepsis/first chart order of antibiotics (point A), the time the chart order was noted by the nurse-in-charge (point B), and the documented time of first dose administration (point C). The mean and median duration (in hours) were then computed between these points. As an additional aim, we briefly presented the outcome of the population used. In phase 2, individual interviews and focused group discussions were done, involving key medical personnel in the sepsis pathway: physicians, nurses, pharmacists, and utility personnel. The data transcribed from these interviews was analyzed through a thematic examination. Results: A total of 508 adult patients were diagnosed with sepsis on record review, 442 of whom met the inclusion criteria. The median time it took for the nurse-in-charge to acknowledge the antibiotic order (points A to B) is 0.73 hours (IQR 0.27-1.7). Meanwhile, the median time between acknowledgment of the order to administration of antibiotics is 1.94 hours (IQR 0.83-6.63). More importantly, the median time from diagnosis-to-first dose (points A to C) is 3.53 hours (IQR 1.59-7.96), while the corresponding mean duration is 5.72 hours. In all cases, 44.6% and 12.4% of loading doses were given within three hours and within one hour after diagnosis, respectively. The all-cause mortality of all qualified cases was 64.7%. A total of 28 key medical personnel were recruited for phase 2. Issues regarding governance, information systems, finances, service delivery, and human resources were identified. In particular, the electronic chart system, a more stable supply of antibiotics, and the new pharmacy at the ER helped facilitate antibiotic delivery. Lack of personnel, gaps in information, and repetitive paperwork were cited as areas for improvement in the existing system. Conclusion: In more than half of the study population, the target time from diagnosis to loading dose of at least 1 hour was not reached. The significant delays in sepsis treatment call for system-wide improvements to hasten the process of antibiotic delivery and reduce the poor outcomes associated with sepsis.
