Item Open Access Increased Costs with Multidrug Resistant Gram Negative Bloodstream Infections Are Primarily Due to Patients with Hospital-Acquired Infections.(Antimicrob Agents Chemother, 2016-12-19) Thaden, Joshua T; Li, Yanhong; Ruffin, Felicia; Maskarinec, Stacey A; Hill-Rorie, Jonathan M; Wanda, Lisa C; Reed, Shelby D; Fowler, Vance GThe clinical and economic impact of bloodstream infections (BSI) due to multidrug resistant (MDR) Gram negative bacteria is incompletely understood. From 2009-2015, all adult inpatients with Gram negative BSI at our institution were prospectively enrolled. MDR status was defined as resistance to ≥3 antibiotic classes. Clinical outcomes and inpatient costs associated with the MDR phenotype were identified. Among 891 unique patients with Gram negative BSI, 292 (33%) were infected with MDR bacteria. In an adjusted analysis, only history of Gram negative infection was associated with MDR BSI versus non-MDR BSI (odds ratio 1.60; 95% confidence interval [CI] 1.19-2.16; P=0.002). Patients with MDR BSI had increased BSI recurrence (1.7% [5/292] vs 0.2% [1/599]; P=0.02) and longer hospital length of stay (median 10.0 vs.8.0 days; P=0.0005). Unadjusted in-hospital mortality did not significantly differ between MDR (26.4% [77/292]) and non-MDR (21.7% [130/599]) groups (P=0.12). Unadjusted mean costs were 1.62 times higher in MDR versus non-MDR BSI ($59,266 vs. $36,452; P=0.003). This finding persisted after adjustment for patient factors and appropriate empiric antibiotic therapy (means ratio 1.18; 95% CI 1.03-1.36; P=0.01). Adjusted analysis of patient sub-populations revealed that increased cost of MDR BSI occurred primarily among patients with hospital-acquired infections (MDR means ratio 1.41, 95% CI 1.10-1.82, P=0.008). MDR Gram negative BSI are associated with recurrent BSI, longer hospital length of stay, and increased mean inpatient costs. MDR BSI in patients with hospital-acquired infections primarily account for the increased cost.Item Open Access Patients' Experiences With Staphylococcus aureus and Gram-negative Bacterial Bloodstream Infections: A Qualitative Descriptive Study and Concept Elicitation Phase To Inform Measurement of Patient-reported Quality of Life.(Clinical infectious diseases : an official publication of the Infectious Diseases Society of America, 2021-07) King, Heather A; Doernberg, Sarah B; Miller, Julie; Grover, Kiran; Oakes, Megan; Ruffin, Felicia; Gonzales, Sarah; Rader, Abigail; Neuss, Michael J; Bosworth, Hayden B; Sund, Zoë; Drennan, Caitlin; Hill-Rorie, Jonathan M; Shah, Pratik; Winn, Laura; Fowler, Vance G; Holland, Thomas LBackground
Although Staphylococcus aureus and gram-negative bacterial bloodstream infections (SAB/GNB) cause substantial morbidity, little is known regarding patient perceptions' of their impact on quality of life (QOL). Guidance for assessing QOL and disease-specific measures are lacking. We conducted a descriptive qualitative study to gain an in-depth understanding of patients' experiences with SAB/GNB and concept elicitation phase to inform a patient-reported QOL outcome measure.Methods
We conducted prospective one-time, in-depth, semi-structured, individual, qualitative telephone interviews 6- 8 weeks following bloodstream infection with either SAB or GNB. Patients were enrolled in an institutional registry (tertiary academic medical center) for SAB or GNB. Interviews were audio-recorded, transcribed, and coded. Directed content analysis identified a priori and emergent themes. Theme matrix techniques were used to facilitate analysis and presentation.Results
Interviews were completed with 30 patients with SAB and 31 patients with GNB. Most patients were at or near the end of intravenous antibiotic treatment when interviewed. We identified 3 primary high-level concepts: impact on QOL domains, time as a critical index, and sources of variability across patients. Across both types of bloodstream infection, the QOL domains most impacted were physical and functional, which was particularly evident among patients with SAB.Conclusions
SAB/GNB impact QOL among survivors. In particular, SAB had major impacts on multiple QOL domains. A combination of existing, generic measures that are purposefully selected and disease-specific items, if necessary, could best capture these impacts. Engaging patients as stakeholders and obtaining their feedback is crucial to conducting patient-centered clinical trials and providing patient-centered care.
