OBJECTIVE To develop a risk score to predict probability of bloodstream infections (BSIs) due to extended-spectrum β-lactamase-producing Enterobacteriaceae (ESBLE). DESIGN Retrospective case-control study. SETTING Two large community hospitals. PATIENTS Hospitalized adults with Enterobacteriaceae BSI between January 1, 2010, and June 30, 2015. METHODS Multivariate logistic regression was used to identify independent risk factors for ESBLE BSI. Point allocation in extended-spectrum β-lactamase prediction score (ESBL-PS) was based on regression coefficients. RESULTS Among 910 patients with Enterobacteriaceae BSI, 42 (4.6%) had ESBLE bloodstream isolates. Most ESBLE BSIs were community onset (33 of 42; 79%), and 25 (60%) were due to Escherichia coli. Independent risk factors for ESBLE BSI and point allocation in ESBL-PS included outpatient procedures within 1 month (adjusted odds ratio [aOR], 8.7; 95% confidence interval [CI], 3.1-22.9; 1 point), prior infections or colonization with ESBLE within 12 months (aOR, 26.8; 95% CI, 7.0-108.2; 4 points), and number of prior courses of β-lactams and/or fluoroquinolones used within 3 months of BSI: 1 course (aOR, 6.3; 95% CI, 2.7-14.7; 1 point), ≥2 courses (aOR, 22.0; 95% CI, 8.6-57.1; 3 points). The area under the receiver operating characteristic curve for the ESBL-PS model was 0.86. Patients with ESBL-PSs of 0, 1, 3, and 4 had estimated probabilities of ESBLE BSI of 0.7%, 5%, 24%, and 44%, respectively. Using ESBL-PS ≥3 to indicate high risk provided a negative predictive value of 97%. CONCLUSIONS ESBL-PS estimated patient-specific risk of ESBLE BSI with high discrimination. Incorporation of ESBL-PS with acute severity of illness may improve adequacy of empirical antimicrobial therapy and reduce carbapenem utilization. Infect Control Hosp Epidemiol 2017;38:266-272.

OBJECTIVESFor patients who require frequent and intensive therapy services after hospitalization, rehabilitation is predominantly provided in skilled nursing facilities (SNFs). Delivering post‐acute rehabilitation in patientsʼ homes offers a potential alternative. Our aim was to describe and evaluate services and functional outcomes and then identify factors associated with the provision of a 30‐day post‐acute care (PAC) bundle of rehabilitation, medical, and social services provided via the Rehabilitation at Home (RaH) program.DESIGNSingle‐arm retrospective review of patients participating in the RaH program.SETTINGMultidisciplinary home‐based delivery of PAC in Manhattan.PARTICIPANTSIndividuals 18 years or older residing in a specified catchment area and qualifying for SNF‐based rehabilitation services from October 2015 to September 2017.RESULTSA total of 237 patients participated in RaH over 264 episodes of care. Participants were predominantly older than 85 years (57%; mean = 84.2; standard deviation [SD] = 10.0 years) and of non‐Hispanic white (70%) race and ethnicity. Most were admitted after hospitalization (88.2%) for 117 different diagnostic related groups. Average length of stay in RaH was 14.2 (SD = 6.5) days with patients receiving 1.83 (SD = 2.22) medical provider, 1.67 (SD = 1.58) nursing, and 5.24 (SD = 1.05) physical therapist visits weekly. Most of the patients fully or almost fully met their goals for bed mobility (65%), bed transfer (69%), chair transfer (67%), and ambulation (64%) with the majority achieving moderate or considerable (61%) global functional improvement. Achieving moderate or considerable global improvement was negatively associated with dementia diagnosis (odds ratio [OR] = .23; 95% confidence interval [CI] = .08‐.71) and positively associated with higher baseline ambulation (OR = 5.51; 95% CI = 2.22‐13.66). At 30 days, 87.3% of participants were living in the community.CONCLUSIONDelivering SNF‐level post‐acute rehabilitation care in patientsʼ homes for a broad range of diagnoses is feasible and associated with functional improvement. This approach may help older adults maintain living status in the community. J Am Geriatr Soc 68:1584‐1593, 2020.
