A Framework for Outpatient Infusion of Antispike Monoclonal Antibodies to High-Risk Patients with Mild-to-Moderate Coronavirus Disease-19: The Mayo Clinic Model.

The administration of spike monoclonal antibody treatment to patients with mild to moderate COVID-19 is very challenging. This article summarizes essential components and processes in establishing an effective spike monoclonal antibody infusion program. Rapid identification of a dedicated physical infrastructure was essential to circumvent the logistical challenges of caring for infectious patients while maintaining compliance with regulations and ensuring the safety of our personnel and other patients. Our partnerships and collaborations among multiple different specialties and disciplines enabled contributions from personnel with specific expertise in medicine, nursing, pharmacy, infection prevention and control, electronic health record (EHR) informatics, compliance, legal, medical ethics, engineering, administration, and other critical areas. Clear communication and a culture in which all roles are welcomed at the planning and operational tables are critical to the rapid development and refinement needed to adapt and thrive in providing this time-sensitive beneficial therapy. Our partnerships with leaders and providers outside our institutions, including those who care for underserved populations, have promoted equity in the access of monoclonal antibodies in our regions. Strong support from institutional leadership facilitated expedited action when needed, from a physical, personnel, and system infrastructure standpoint. Our ongoing real-time assessment and monitoring of our clinical program allowed us to improve and optimize our processes to ensure that the needs of our patients with COVID-19 in the outpatient setting are met.

Clinical effectiveness of flucloxacillin delivery using an elastomeric device for outpatient parenteral antimicrobial therapy.

There has been a surging interest in using elastomeric infusion devices to deliver outpatient parenteral antimicrobial therapy (OPAT), which is more cost-effective than standard antibiotic administration, which requires multiple daily home visits. This has been particularly important since the outbreak of the coronavirus pandemic, because reducing patient contact can also help to minimise transmission of COVID-19 to outpatients who are at a high risk of COVID-19-triggered complications. In this retrospective study, the clinical effectiveness of intravenous (IV) infusion of flucloxacillin using an elastomeric device was explored in a convenience sample of patients. Patients with three primary infective diagnoses-bloodstream infection, non-vertebral osteomyelitis and vertebral osteomyelitis-were included in the analyses. In non-vertebral osteomyelitis patients, Accufuser antibiotic infusion shortened the course of OPAT care relative to standard antibiotic administration (p<.05). In contrast, in vertebral osteomyelitis patients, it prolonged the course of OPAT care relative to standard administration (p<.05). In patients with bloodstream infections, no significant difference was found between the treatment modes (p=.93). Thus, the clinical effectiveness of Accufuser antibiotic infusion varies among patients with different infective diagnoses, and there seems to be a complex relationship between the method of antibiotic delivery and the patient's condition.

Home Infliximab Infusions Are Associated With Suboptimal Outcomes Without Cost Savings in Inflammatory Bowel Diseases.

INTRODUCTION: Biologic agents including infliximab are effective but costly therapies in the management of inflammatory bowel disease (IBD). Home infliximab infusions are increasingly payer-mandated to minimize infusion-related costs. This study aimed to compare biologic medication use, health outcomes, and overall cost of care for adult and pediatric patients with IBD receiving home vs office- vs hospital-based infliximab infusions. METHODS: Longitudinal patient data were obtained from the Optum Clinformatics Data Mart. The analysis considered all patients with IBD who received infliximab from 2003 to 2016. Primary outcomes included nonadherence (≥2 infliximab infusions over 10 weeks apart in 1 year) and discontinuation of infliximab. Secondary outcomes included outpatient corticosteroid use, follow-up visits, emergency room visits, hospitalizations, surgeries, and cost outcomes (out-of-pocket costs and annual overall cost of care). RESULTS: There were 27,396 patients with IBD (1,839 pediatric patients). Overall, 5.7% of patients used home infliximab infusions. These patients were more likely to be nonadherent compared with both office-based (22.2% vs 19.8%; P = .044) and hospital-based infusions (22.2% vs 21.2%; P < .001). They were also more likely to discontinue infliximab compared with office-based (44.7% vs 33.7%; P < .001) or hospital-based (44.7% vs 33.4%; P < .001) infusions. On Kaplan-Meier analysis, the probabilities of remaining on infliximab by day 200 of therapy were 64.4%, 74.2%, and 79.3% for home-, hospital-, and office-based infusions, respectively (P < .001). Home infliximab patients had the highest corticosteroid use (cumulative corticosteroid days after IBD diagnosis: home based, 238.2; office based, 189.7; and hospital based, 208.5; P < .001) and the fewest follow-up visits. Home infusions did not decrease overall annual care costs compared with office infusions ($49,149 vs $43,466, P < .001). DISCUSSION: In this analysis, home infliximab infusions for patients with IBD were associated with suboptimal outcomes including higher rates of nonadherence and discontinuation of infliximab. Home infusions did not result in significant cost savings compared with office infusions.

Nutrición enteral domiciliaria en el paciente con patología neurológica de un área de salud del sureste español / Home enteral nutrition in patients with neurological disease in an area of the southeast of Spain

Introducción: la desnutrición en el paciente neurológico presenta una alta prevalencia, aumentando las complicaciones y disminuyendo la calidad de vida. La nutrición artificial minimiza el riesgo de malnutrición. En los últimos años, en Murcia, se pone en marcha una vía clínica de adecuación a la Guía Nacional de Nutrición Enteral Domiciliaria (NED) para optimizar este recurso y reducir la variabilidad de prescripción. Objetivo: analizar las características de la NED en el paciente neurológico, de un área de salud de Murcia, antes y después de la adecuación a las directrices nacionales. Método: diseño observacional de corte transversal. Análisis y comparación de las muestras NED de adultos del Área 1 de salud de Murcia, en 2010 y 2014. Resultados: la patología más asociada a las prescripciones de NED fue la neurológica. La vía de administración más utilizada fue la oral, aunque desciende en la muestra de 2014 a favor de la sonda de nutrición y ostomía. El tipo de fórmula más usado en 2010 fue la no específica. Tras la vía clínica se reduce el uso de fórmulas específicas, disminuyendo especialmente las fórmulas hiperproteicas y/o hipercalóricas. Conclusiones: la implementación de una vía clínica de adecuación a la Guía Nacional NED ha provocado un cambio en la realidad de este tipo de nutrición artificial en el Área 1 de salud del Servicio Murciano de Salud, consiguiendo normalizar su uso bajo criterios unificados y profesionales especializados. Finalmente, estos logros se han generalizado a toda la región

Introduction: malnutrition in patients with neurological disease is very prevalent, worsening their complications and diminishing their quality of life. For that reason, nutritional support can provide a reduction in comorbidities. Over the past years, in Murcia (southeast of Spain), a clinical pathway has been stablished in accordance to the National Home Enteral Nutrition guide (HEN) to optimize this resource and reduce the prescription gap. Objective: to analyze the HEN characteristics in neurological patients in an area of Murcia, before and after the adequacy of the national recommendations. Method: observational cross-sectional study. Analysis and comparison of HEN in health area no. 1 in Murcia in 2010 and 2014. Results: the most prevalent cause for HEN was neurological disease. In 2010, oral nutrition was the most used way compared with 2014, when it had changed to enteral nutrition through feeding tube or ostomy. Non-specific formula was the most frequently used in 2010. However, after the establishment of the clinical pathway there was a reduction in specific enteral formula use, specially hypercaloric and hyperproteic. Conclusions: the implementation of a clinical pathway according to the National HEN guide has caused a change in the reality of artificial nutrition in health area no. 1 in Murcia (Spain), which means a standardization of its use under unified criteria made by specialized professionals. Finally, due to these results, this clinical pathway has been generalized to the rest of the region

Economic Burden of Home Antimicrobial Therapy: OPAT Versus Oral Therapy.

BACKGROUND: There is increasing evidence that outpatient parenteral antimicrobial therapy (OPAT) is overused for children and that outcomes with oral therapy are equivalent. Our objective was to compare economic burden between OPAT and oral therapy, accounting for direct and indirect costs and caregiver quality of life (QoL). METHODS: We conducted a prospective cohort study of caregivers for children after hospitalization who were treated with prolonged antimicrobial therapy. We collected data about missed work and school and time spent administering therapy. Caregivers completed the Pediatric Quality of Life Inventory to assess QoL. Clinical information included length of stay, treatment indication, and type of therapy (OPAT versus oral therapy). Direct medical costs were obtained by using a microcosting system and accounted for medication, supplies, and home-nursing visits. The primary cost outcome was the mean daily cost of therapy. Multivariable models were developed to adjust for potential confounders. RESULTS: Two hundred and twelve caregivers completed surveys: 123 (58%) for oral therapy and 89 (42%) for OPAT. Caregivers administering OPAT reported more missed work, missed school for their children, time with daily medication administration (90 vs 6 minutes; P < .01) and lower QoL scores (77.8 vs 68.9) than caregivers administering oral therapy. The mean daily cost was $65 (95% confidence interval: $51-$78) for OPAT and $7 (95% confidence interval: $4-$9) for oral therapy. Relative differences in cost and QoL between groups did not change after model adjustment. CONCLUSIONS: The overall burden of OPAT is substantially higher than that of oral therapy, including higher direct and indirect costs and greater impact on caregiver QoL. These findings strongly support efforts to use oral therapy in place of OPAT when clinically appropriate.

Infectious Diseases Specialty Intervention Is Associated With Better Outcomes Among Privately Insured Individuals Receiving Outpatient Parenteral Antimicrobial Therapy.

BACKGROUND: Outpatient parenteral antimicrobial therapy (OPAT) can be managed by specialists in infectious diseases (ID) or by other physicians. Better management of OPAT can reduce the likelihood of readmission or emergency department (ED) use. The relative success of ID specialists and other physicians in managing OPAT has received little study. METHODS: We analyzed a national database of insurance claims for privately insured individuals under age 65, locating inpatient acute-care stays in 2013 and 2014 that were followed by OPAT. Through propensity scoring, patients who received outpatient ID intervention (ID-led OPAT) were matched 1-to-1 with those who did not (Other OPAT). We estimated regression models of hospital and ED admissions and of total healthcare payments over the first 30 days after discharge. RESULTS: The final analytic sample of 8200 observations was well balanced on clinical and demographic characteristics. Soft-tissue infection and osteomyelitis were the most common infections in the index event, each affecting more than 40% of individuals. Relative to those with Other OPAT, people with ID-led OPAT had lower odds of an ED admission (odds ratio [OR] 0.449, 95% confidence interval [CI] 0.311-0.645) or hospitalization (OR 0.661, 95% CI 0.557-0.791) over 30 days, and they accumulated $1488 less in total healthcare payments (95% CI -2 688.56--266.58). CONCLUSIONS: Among privately insured individuals below age 65, ID consultations during OPAT are associated with large and significant reductions in the rates of ED admission and hospital admission in the 30 days after index events, as well as lower total healthcare spending.

Ambulatory Inotrope Infusions in Advanced Heart Failure: A Systematic Review and Meta-Analysis.

OBJECTIVES: This study sought to systematically review the available evidence of risks and benefits of ambulatory intravenous inotrope therapy in advanced heart failure (HF). BACKGROUND: Ambulatory inotrope infusions are sometimes offered to patients with advanced Stage D HF; however, an understanding of the relative risks and benefits is lacking. METHODS: On August 7, 2016, we searched SCOPUS, Web of Science, Ovid EMBASE, and Ovid MEDLINE for studies of long-term use of intravenous inotropes in outpatients with advanced HF. Meta-analysis was performed using random effects models. RESULTS: A total of 66 studies (13 randomized controlled trials and 53 observational studies) met inclusion criteria. Most studies were small and at high risk for bias. Pooled rates of death (41 studies), all-cause hospitalization (15 studies), central line infection (13 studies), and implantable cardioverter-defibrillator shocks (3 studies) of inotropes were 4.2, 22.2, 3.6, and 2.4 per 100 person-months follow-up, respectively. Improvement in New York Heart Association (NYHA) functional class was greater in patients taking inotropes than in controls (mean difference of 0.60 NYHA functional classes; 95% confidence interval [CI]: 0.22 to 0.98; p = 0.001; 5 trials). There was no significant difference in mortality risk in those taking inotropes compared with controls (pooled risk ratio: 0.68; 95% CI: 0.40 to 1.17; p = 0.16; 9 trials). Data were too limited to pool for other outcomes or to stratify by indication (i.e., bridge-to-transplant or palliative). CONCLUSIONS: High-quality evidence for the risks and benefits of ambulatory inotrope infusions in advanced HF is limited, particularly when used for palliation. Available data suggest that inotrope therapy improves NYHA functional class and does not impact survival.

Catheter Occlusion in Home Infusion: The Influence of Needleless Connector Design on Central Catheter Occlusion.

Thrombotic catheter occlusion is a common complication associated with central venous catheters (CVCs). A wide variety of needleless connectors that differ greatly in design and function are available for use with CVCs; however, there are a limited number of studies comparing the catheter occlusion rate associated with differently designed needleless connectors. This retrospective observational study compared occlusion rates associated with a split-septum neutral-displacement needleless connector versus those of a solid-surface neutral-reflux needleless connector in patients undergoing home infusion therapy. The neutral-reflux needleless connector was associated with a significant reduction in occlusion rate and thrombolytic use versus the neutral-displacement needleless connector.

Clinical efficacy, cost analysis and patient acceptability of outpatient parenteral antibiotic therapy (OPAT): a decade of Sheffield (UK) OPAT service.

Outpatient parenteral antimicrobial therapy (OPAT) has evolved relatively slowly in the UK. This study describes the OPAT service based in a large UK teaching hospital in Sheffield, and examines the clinical efficacy, patient acceptability and costs saved over a 10-year period. Data on 3812 episodes of OPAT administered between January 2006 and January 2016 were retrieved from a prospectively maintained electronic database. This study compared the real costs of the OPAT service with estimated costs of conventional inpatient care for these patient episodes, and analysed patient feedback questionnaires that were administered randomly between January 2014 and January 2015. A wide range of infections were managed during the 10-year period. Skin and soft tissue infections accounted for 57% of OPAT episodes. The total number of bed-days saved was 49,854. A successful outcome (cure or improvement) was found in 3357 (88%) episodes. Re-admission occurred in 265 (7%) episodes. The rates of healthcare-associated infections were low: 15 intravenous-line-related infections were recorded (0.3 per 1000 OPAT patient-days). Patient acceptance and satisfaction with OPAT were high. OPAT cost 15%, 39%, 40% and 44% of inpatient costs for an infectious diseases unit, national average costs, other departments (non-infectious diseases unit), and the minimum national average costs for each diagnostic category, respectively. This study shows that OPAT is safe, clinically efficacious and acceptable for treating a wide range of infections with high levels of patient satisfaction and substantial cost savings.

Determining the Risk of Sepsis Using Nurse-Compounded Elastomeric Pumps for Continuous Infusion in Outpatient Parenteral Antibiotic Therapy.

Limited availability of compounded antibiotics used for continuous infusion outpatient parenteral antibiotic therapy (OPAT) can delay or interrupt an OPAT course. To solve this problem, OPAT nurses at a hospital in Australia have been compounding elastomeric pumps for immediate use. The incidence of sepsis in 5014 patients before and after the introduction of nurse compounding was compared. There were no cases of laboratory-confirmed bloodstream infection among the nurse-compounded group compared with 2 cases (0.045/1000 catheter days) among the control group without nurse compounding (P = .16). No compounding medication errors occurred in more than 180 patient years of follow-up among the nurse compounding group. Nurse compounding can be a safe and convenient alternative when immediate access to preloaded elastomeric pumps is required.

Safety Risks Among Home Infusion Nurses and Other Home Health Care Providers.

In the United States, home health care (HHC) is a rapidly growing industry and home infusion therapy is a rapidly growing market. HHC can present substantial occupational safety and health (OSH) risks. This article summarizes major OSH risks relevant to home infusion therapy by illustrating them through real-life scenarios collected systematically using qualitative research methods by the National Institute for Occupational Safety and Health-funded research projects at the University of Massachusetts Lowell. The need for home infusion therapy will continue to grow in the future, and safety interventions to prevent or minimize OSH risks are essential.

Continuous Intravenous Milrinone Therapy in Pediatric Outpatients.

Milrinone is a phosphodiesterase 3 inhibitor with both positive inotropic and vasodilator properties. Administered as a continuous infusion, milrinone is indicated for the short-term treatment of patients with acute decompensated heart failure. Despite limited data supporting long-term milrinone therapy in adults with congestive heart failure, children managed as outpatients may benefit from continuous milrinone as a treatment for cardiac dysfunction, as a destination therapy for cardiac transplant, or as palliative therapy for cardiomyopathy. The aim of this article is to review the medical literature and describe a home infusion company's experience with pediatric outpatient milrinone therapy.

Administration of Home Intravenous Chemotherapy to Children by their Parents.

OBJECTIVES: Caring for a child with cancer can disrupt family life and financial stability, in addition to affecting the child's social, emotional, and educational development. Health care providers must consider ways to minimize the negative impact of illness and hospitalization on the child and family. This study evaluates a nationwide initiative to educate and support parents to administer chemotherapy to their child in their home. METHOD: A questionnaire was circulated to parents participating in a home chemotherapy program from 2009 to 2014 (n = 140), seeking their perspective on the education program, and the benefits and concerns associated with administering home chemotherapy. Data analysis was conducted using a combination of descriptive statistics and content analysis. RESULTS: Questionnaires were received from 108 parents (response rate = 77%). Overall, the program was positively evaluated with 100% of parents (n = 108) reporting that the training met their needs. More than one-third of parents (41%, n = 44) initially felt nervous about home chemotherapy but reported that the education program helped assuage their concerns. Benefits included reduced financial costs, reduced travel time to hospital, less disruption to family life, and less stress for the child and family. No medication errors were reported during the evaluation period. CONCLUSION: An important feature of the program is the partnership approach, which ensures that parents' decision to enter the program is informed, appropriate for their situation, and centered on the needs of the child.

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.

INTRODUCTION: This prospective, observational study evaluated transanal dearterialization (THD) efficacy and safety in grade 2-4 hemorrhoids (HD). METHODS: THD was performed under sedation-locoregional anesthesia in 402 outpatients. Patients had follow-up evaluation 3 days, 2 weeks, 1, 6 and 12 months postoperatively. Postoperative complications and recurrence of symptoms at 12 months were analyzed. The relationship between the learning curve and the number of postoperative complications was studied. RESULTS: Mean patient age was 46.4 (range 20-85) years. A total of 268 patients (66.6%) were male. Sixteen patients (4.0%) had grade 2 HD, 210 (52.2%) had grade 3 and 176 (43.8%) had grade 4 HD. Surgery lasted 23 (17-34) min. A total of 67 patients had complications: bleeding in 10 patients (2.5%), hemorrhoidal thromboses in 10 (2.5%), perianal fistulas in 5 (1.2%), fissures in 14 (3.5%), urinary retention in 3 (0.8%), residual prolapse in 19 (4.7%), severe anal pain in 3 (0.8%), and perianal abscess in 3 patients (0.8%). Recurrent HD occurred in 6.3% (1/ 16) of grade 2 HD patients, 5.8% (12/210) of grade 3 patients and 9.7% (17/176) of grade 4 patients. Twelve months after THD, bleeding was controlled in 363 patients (90.5%), prolapse was controlled in 391 (97.3%) and pain markedly improved in 390 patients (97%). CONCLUSION: THD appears safe and effective for grade 2-4 HD, and the number of complications decreased with increasing surgeon experience. THD advantages include mild pain, fast recovery, early return to daily activities and low incidence of complications

Infusion treatments and deep brain stimulation in Parkinson's Disease: The role of nursing.

Parkinson's Disease (PD) represents one of the most common neurodegenerative disorders in the elderly. PD is caused by a loss of dopaminergic cells in the substantia nigra pars compacta. The motor cardinal signs include a resting tremor, bradykinesia, rigidity and postural reflex impairment. Although levodopa represents the gold standard also in the advanced stage of the disease, over the years most patients develop disabling motor fluctuations, dyskinesias, and non-motor complications, which are difficult to manage. At this stage, more complex treatment approaches, such as infusion therapies (subcutaneous apomorphine and intraduodenal levodopa) and deep brain stimulation of the subthalamic nucleus or the globus pallidus internus should be considered. All three procedures require careful selection and good compliance of candidate patients. In particular, infusional therapies need adequate training both of caregivers and nursing staff in order to assist clinicians in the management of patients in the complicated stages of disease.

From a Suspect Victim to the Holmes: The Unexpected Value of a Home-Made Mobile Chemotherapy Medication Administration System.

Nurse used to be the first one to be investigated in a drug adverse event. Our newly hospital-wide implemented home-made mobile chemotherapy medication support system, which has released our nurses from the traditional heavy 2-nurse-double-checking loading, was unexpectedly used to protect our nurses from being suspected in a recent event of over delivery of infusion. The outcome turned us to reexamine the device maintenance and test protocols.

[Outpatient parenteral antibiotic therapy (OPAT)]. / Ambulantní parenterální antibiotická terapie (OPAT).

Traditionally, parenteral (i. e. intravenous) antimicrobial therapy has been used in inpatients with various bacterial infections. In recent decades there has been growing experience with outpatient parenteral antimicrobial therapy, mainly in the USA and western Europe. This article provides basic information on OPAT, based on available literature and the author´s experience on running OPAT service in the UK.

Vascular access complications during outpatient parenteral antimicrobial therapy at home: a retrospective cohort study.

OBJECTIVES: The need for indwelling vascular access for outpatient parenteral antimicrobial therapy (OPAT) places patients at risk of vascular access complications. The purpose of this study was to describe vascular access complications during OPAT at home, and identify factors associated with their occurrence. METHODS: All OPAT courses carried out at home for patients at Cleveland Clinic in 2013 were identified from the institution's OPAT registry. The first OPAT course per patient was included. Vascular access complications that occurred during the treatment course were abstracted from the electronic medical record. Only complications that triggered a clinical intervention were included. RESULTS: The 1461 included OPAT courses encompassed 33,579 OPAT days of treatment. One-hundred-and-forty-four vascular access complications occurred in 131 OPAT courses (9% of OPAT courses, 4.29 complications per 1000 OPAT days). The most common complication was occlusion (53% of all complications). Hickman catheters [incidence rate ratio (IRR) 0.20, 95% CI 0.03-0.63] and indwelling ports (IRR 0.25, 95% CI 0.04-0.78) were associated with lower complication rates than peripherally inserted central catheters, as was increasing age (IRR 0.99, 95% CI 0.98-1.00). Log OPAT duration (IRR 1.60, 95% CI 1.28-2.03), female sex (IRR 1.62, 95% CI 1.16-2.28) and injection drug use (IRR 3.32, 1.16-7.46) were associated with increased risk of vascular access complications. CONCLUSIONS: Nine percent of OPAT courses at home have at least one vascular access complication requiring clinical intervention. Longer OPAT duration, younger age, female sex and injection drug use are associated with increased risk of vascular access complications.
