Risk factors of 30-days re-hospitalization after Hospital at Home in a cohort of patients treated with parenteral therapy

Safety of Outpatient Parenteral Antimicrobial Therapy in Nonagenarians

Background

Although widely accepted for adults, the safety of outpatient parenteral antimicrobial therapy (OPAT) in very old patients has not been examined.

Methods

Nonagenarians (age ≥90 years) discharged from the hospital on OPAT over a 5-year period were identified from the Cleveland Clinic OPAT Registry. Three matched controls (<90 years) were selected for each nonagenarian. Times to OPAT-related emergency department (ED) visit and OPAT-related readmission were compared across the 2 groups in multivariable subdistribution proportional hazards competing risks regression models. Incidence of adverse drug events and vascular access complications were compared using negative binomial regression.

Results

Of 126 nonagenarians and 378 controls, 7 were excluded for various reasons. Among the remaining 497 subjects, 306 (62%) were male, 311 (63%) were treated for cardiovascular or osteoarticular infections, and 363 (73%) were discharged to a residential health care facility. The mean (SD) ages of nonagenarians and controls were 92 (2) and 62 (16) years, respectively. Compared with matched controls, being a nonagenarian was not associated with increased risk of OPAT-related ED visit (hazard ratio [HR], 0.77; 95% CI, 0.33-1.80; P = .55), OPAT-related readmission (HR, 0.78; 95% CI, 0.28-2.16; P = .63), adverse drug event from OPAT medications (incidence rate ratio [IRR], 1.00; 95% CI, 0.43-2.17; P = .99), or vascular access complications (IRR, 0.66; 95% CI, 0.27-1.51; P = .32). Nonagenarians had a higher risk of death overall (HR, 2.64; 95% CI, 1.52-4.58; P < .001), but deaths were not from OPAT complications.

Conclusions

Compared with younger patients, OPAT in nonagenarians is not associated with higher risk of OPAT-related complications. OPAT can be provided as safely to nonagenarians as to younger patients.

2018 Infectious Diseases Society of America Clinical Practice Guideline for the Management of Outpatient Parenteral Antimicrobial Therapy

A panel of experts was convened by the Infectious Diseases Society of America (IDSA) to update the 2004 clinical practice guideline on outpatient parenteral antimicrobial therapy (OPAT) [1]. This guideline is intended to provide insight for healthcare professionals who prescribe and oversee the provision of OPAT. It considers various patient features, infusion catheter issues, monitoring questions, and antimicrobial stewardship concerns. It does not offer recommendations on the treatment of specific infections. The reader is referred to disease- or organism-specific guidelines for such support.

Environmental Exposures and the Risk of Central Venous Catheter Complications and Readmissions in Home Infusion Therapy Patients

BACKGROUND Patients are frequently discharged with central venous catheters (CVCs) for home infusion therapy. OBJECTIVE To study a prospective cohort of patients receiving home infusion therapy to identify environmental and other risk factors for complications. DESIGN Prospective cohort study between March and December 2015. SETTING Home infusion therapy after discharge from academic medical centers. PARTICIPANTS Of 368 eligible patients discharged from 2 academic hospitals to home with peripherally inserted central catheters and tunneled CVCs, 222 consented. Patients remained in the study until 30 days after CVC removal. METHODS Patients underwent chart abstraction and monthly telephone surveys while the CVC was in place, focusing on complications and environmental exposures. Multivariable analyses estimated adjusted odds ratios and adjusted incident rate ratios between clinical, demographic, and environmental risk factors and 30-day readmissions or CVC complications. RESULTS Of 222 patients, total parenteral nutrition was associated with increased 30-day readmissions (adjusted odds ratio, 4.80 [95% CI, 1.51-15.21) and CVC complications (adjusted odds ratio, 2.41 [95% CI, 1.09-5.33]). Exposure to soil through gardening or yard work was associated with a decreased likelihood of readmissions (adjusted odds ratio, 0.09 [95% CI, 0.01-0.74]). Other environmental exposures were not associated with CVC complications. CONCLUSIONS complications and readmissions were common and associated with the use of total parenteral nutrition. Common environmental exposures (well water, cooking with raw meat, or pets) did not increase the rate of CVC complications, whereas soil exposures were associated with decreased readmissions. Interventions to decrease home CVC complications should focus on total parenteral nutrition patients. Infect Control Hosp Epidemiol 2016;1-8.
