Sepsis Order Set Use Associated with Increased Care Value.

ABSTRACT

BACKGROUND: Sepsis is common and expensive and there is evidence that sepsis order sets may help improve care. There is very incomplete evidence of the effects of sepsis order sets on the value of care produced by hospitals or the societal costs of sepsis care. RESEARCH QUESTION In patients hospitalized for sepsis, is the receipt a of a sepsis order set vs. no order set associated with improved value of care, defined as decreased hospital mortality, decreased hospital direct variable costs and decreased societal spending on hospitalizations? STUDY DESIGN AND METHODS: Retrospective cohort study of patients discharged with sepsis ICD-10 codes over two years from a large integrated delivery system. Using a propensity score, sepsis order set users were matched to non-users to study the association between sepsis order set use and the value of care from the hospital and societal perspective. The association between order set receipt and hospital mortality, direct variable cost, and hospital revenue were also examined in a priori defined subgroups of sepsis severity and hospital mortality. RESULTS: 97,249 patients were included in the study with 52,793 (54%) receiving the sepsis order set. 55,542 patients were included in the propensity score match analysis, 27,771 in each group. Recipients of the sepsis order set had a 3.3% lower hospital mortality rate, a $1487 lower median direct variable total cost (P < 0.01 for both). Median payer neutral reimbursement (PNR), a proxy for hospital revenue and thus societal costs, was $465 lower for sepsis order set users (P < 0.01). Receipt of the sepsis order set was associated with an $1022 increase in contribution margin, the difference between direct variable costs and PNR per patient. INTERPRETATION: Receipt of the sepsis order set was associated with improved value of care, from both a hospital and societal perspective.
