Importance Sepsis is present in many hospitalizations that culminate in death. The contribution of sepsis to these deaths, and the extent to which they are preventable, is unknown. Objective To estimate the prevalence, underlying causes, and preventability of sepsis-associated mortality in acute care hospitals. Design, Setting, and Participants Cohort study in which a retrospective medical record review was conducted of 568 randomly selected adults admitted to 6 US academic and community hospitals from January 1, 2014, to December 31, 2015, who died in the hospital or were discharged to hospice and not readmitted. Medical records were reviewed from January 1, 2017, to March 31, 2018. Main Outcomes and Measures Clinicians reviewed cases for sepsis during hospitalization using Sepsis-3 criteria, hospice-qualifying criteria on admission, immediate and underlying causes of death, and suboptimal sepsis-related care such as inappropriate or delayed antibiotics, inadequate source control, or other medical errors. The preventability of each sepsis-associated death was rated on a 6-point Likert scale. Results The study cohort included 568 patients (289 [50.9%] men; mean [SD] age, 70.5 [16.1] years) who died in the hospital or were discharged to hospice. Sepsis was present in 300 hospitalizations (52.8%; 95% CI, 48.6%-57.0%) and was the immediate cause of death in 198 cases (34.9%; 95% CI, 30.9%-38.9%). The next most common immediate causes of death were progressive cancer (92 [16.2%]) and heart failure (39 [6.9%]). The most common underlying causes of death in patients with sepsis were solid cancer (63 of 300 [21.0%]), chronic heart disease (46 of 300 [15.3%]), hematologic cancer (31 of 300 [10.3%]), dementia (29 of 300 [9.7%]), and chronic lung disease (27 of 300 [9.0%]). Hospice-qualifying conditions were present on admission in 121 of 300 sepsis-associated deaths (40.3%; 95% CI 34.7%-46.1%), most commonly end-stage cancer. Suboptimal care, most commonly delays in antibiotics, was identified in 68 of 300 sepsis-associated deaths (22.7%). However, only 11 sepsis-associated deaths (3.7%) were judged definitely or moderately likely preventable; another 25 sepsis-associated deaths (8.3%) were considered possibly preventable. Conclusions and Relevance In this cohort from 6 US hospitals, sepsis was the most common immediate cause of death. However, most underlying causes of death were related to severe chronic comorbidities and most sepsis-associated deaths were unlikely to be preventable through better hospital-based care. Further innovations in the prevention and care of underlying conditions may be necessary before a major reduction in sepsis-associated deaths can be achieved.

Crude mortality rates were higher in sepsis cases that failed versus passed SEP-1, but there was no difference after adjusting for clinical characteristics and severity of illness. Delays in antibiotic administration were associated with higher mortality but only accounted for a small fraction of SEP-1 failures. SEP-1 may not clearly differentiate between high- and low-quality care, and detailed risk adjustment is necessary to properly interpret associations between SEP-1 compliance and mortality.

Background Although outpatient parenteral antimicrobial therapy (OPAT) is generally considered safe, patients are at risk for complications and thus require close monitoring. The purpose of this study is to determine how OPAT programs are structured and how United States–based infectious diseases (ID) physicians perceive barriers to safe OPAT care. Methods We queried members of the Emerging Infections Network (EIN) between November and December 2018 about practice patterns and barriers to providing OPAT. Results A total of 672 members of the EIN (50%) responded to the survey. Seventy-five percent of respondents were actively involved in OPAT, although only 37% of respondents reported that ID consultation was mandatory for OPAT. The most common location for OPAT care was at home with home health support, followed by post–acute care facilities. Outpatient and inpatient ID physicians were identified as being responsible for monitoring laboratory results (73% and 54% of respondents, respectively), but only 36% had a formal OPAT program. The majority of respondents reported a lack of support in data analysis (80%), information technology (66%), financial assistance (65%), and administrative assistance (60%). The perceived amount of support did not differ significantly across employment models. Inability to access laboratory results in a timely manner, lack of leadership awareness of OPAT value, and failure to communicate with other providers administering OPAT were reported as the most challenging aspects of OPAT care. Conclusions ID providers were highly involved in OPAT, but only one-third of respondents had a dedicated OPAT program. Lack of financial and institutional support were perceived as significant barriers to providing safe OPAT care.

We compared sepsis "time zero" and Centers for Medicare and Medicaid Services (CMS) SEP-1 pass rates among 3 abstractors in 3 hospitals. Abstractors agreed on time zero in 29 of 80 (36%) cases. Perceived pass rates ranged from 9 of 80 cases (11%) to 19 of 80 cases (23%). Variability in time zero and perceived pass rates limits the utility of SEP-1 for measuring quality.

Intravenous (IV) minocycline is increasingly used to treat infections caused by multi-drug resistant (MDR)-Acinetobacter baumannii. Despite being approved nearly 50 years ago, published information on its pharmacokinetic (PK) prolife is limited. This multi-center study examined the PK and probability of pharmacokinetic-pharmacodynamic (PK-PD) target attainment profile of IV minocycline in critically ill patients, with suspected or documented infection with Gram-negative bacteria. The PK study population included 55 patients who received a single 200 mg IV dose of minocycline. Plasma PK samples were collected pre-dose and 1, 4, 12, 24, 36, and 48 hours after initiation of minocycline. Total and unbound minocycline concentrations were determined at each timepoint. Probabilities of achieving the PK-PD targets associated with stasis and 1-log killing (fAUC:MIC of 12 and 18, respectively) were evaluated. A two-compartment population PK model with zero-order IV input and first-order elimination, which estimated a constant fraction unbound (fub) for minocycline, best characterized the total and unbound plasma minocycline concentration-time data. The only two covariates retained in the final PK model were body surface area [associated with central volume of distribution] and albumin (associated with fub). In the PK-PD target attainment analyses, minocycline 200 mg IV Q12H was predicted to result in a suboptimal PK-PD profile for patients with A. baumannii infections with MIC values ≥ 1 mg/L. These findings cast uncertainty on the appropriateness of the current minocycline FDA susceptibility breakpoints and suggest that clinicians should strongly consider only combination antibiotic therapy with IV minocycline for all patients with serious Acinetobacter sp. infections.
