چکیده

Background. Procalcitonin has emerged as a promising biomarker of bacterial infection. Published literature demonstrates that use of procalcitonin testing and an associated treatment pathway reduces duration of antibiotic therapy without impacting mortality. Procalcitonin testing, however, is an additional expenditure which may or may not be offset by treatment-related financial gains. The cost-effectiveness of procalcitonin use has not been established in patients with sepsis. The objective of this study was to determine the cost-effectiveness of utilizing a procalcitonin algorithm to guide patient care compared with standard care in patients with sepsis. Methods. A decision analytic model was developed from a hospital perspective. Published clinical and economic data populated a cost-minimization and a cost-utility analysis across 10,000 hypothetical patient scenarios. Univariate and probabilistic sensitivity analyses assessed the robustness of our model across all likely scenarios. Results. Our model predicted that the use of a procalcitonin algorithm dominated standard care (i.e., increased effectiveness with decreased costs). The incremental cost of procalcitonin use vs standard care saved $168 per septic episode while increasing a patients’ quality of life. Secondary analyses found variables which had the potential to alter results included: compliance with algorithm adherence (<25.2%), days of antibiotic reduction (<0.28), the probability of antimicrobial-induced nephrotoxicity (<11%), or decreased nephrotoxicity through antimicrobial reduction (<0.9%). Under these circumstances, our model predicted a higher incremental cost of procalcitonin use; however, procalcitonin use remained cost-effective at our predetermined willingness-to-pay threshold. Conclusion. Our model predicts that use of a procalcitonin-guided treatment algorithm in sepsis patients may be cost-effective. Implementing a procalcitonin-guided treatment algorithm in septic patients could improve the quality of care and decrease costs in patients with sepsis. Disclosures.

Procalcitonin-guided therapy in intensive care unit patients with severe sepsis and septic shock – a systematic review and meta-analysis

INTRODUCTION Procalcitonin (PCT) algorithms for antibiotic treatment decisions have been studied in adult patients from primary care, emergency department, and intensive care unit (ICU) settings, suggesting that procalcitonin-guided therapy may reduce antibiotic exposure without increasing the mortality rate. However, information on the efficacy and safety of this approach in the most vulnerabl...

Procalcitonin: A Reliable Marker for the Diagnosis of Neonatal Sepsis

Objective(s) In the last few years, serum procalcitonin has been proposed as an early marker of infections in neonates, with varying results. In this study, we aimed to investigate the value of procalcitonin, and C- reactive protein in establishing the diagnosis of neonatal sepsis. Materials and Methods Blood samples were collected at admission from 69 neonates with suspected infection (admi...

Effect of Sodium Selenite Administration and Procalcitonin-Guided Therapy on Mortality in Patients With Severe Sepsis or Septic Shock: A Randomized Clinical Trial.

IMPORTANCE High-dose intravenous administration of sodium selenite has been proposed to improve outcome in sepsis by attenuating oxidative stress. Procalcitonin-guided antimicrobial therapy may hasten the diagnosis of sepsis, but effect on outcome is unclear. OBJECTIVE To determine whether high-dose intravenous sodium selenite treatment and procalcitonin-guided anti-infectious therapy in pati...

Procalcitonin as a Marker of Neonatal Sepsis in Intensive Care Units

Background: The appropriateness of using serum levels of procalcotonin (PCT) for early diagnosis of newborn sepsis is still controversial. Therefore, the objective of the present study was to compare the usefulness of PCT with those of serum levels of C-reactive protein (CRP) and white blood cell (WBC) counts in the diagnosis and response to treatment of neonatal sepsis. Methods: A total of 47 ...

Significance of Serum Procalcitonin Level in the Early Diagnosis of Neonatal Sepsis

Background: Sepsis in neonates presents itself with non-specific clinical features which makes early diagnosis difficult. However, procalcitonin (PCT) and other inflammatory markers have recently been considered as sensitive markers for the early detection of neonatal sepsis. Therefore, the present study aimed to determine the diagnostic value of PCT in the early detection of neonatal sepsis an...
