Characterizing Patients Presenting on Hospital Admission With Central Line-Associated Bloodstream Infections: A Multicenter Study.

BACKGROUND: There are no systematic measures of central line-associated bloodstream infections (CLABSIs) in patients maintaining central venous catheters (CVCs) outside acute care hospitals. To clarify the burden of CLABSIs in these patients, we characterized patients with CLABSI present on hospital admission (POA). METHODS: Retrospective cross-sectional analysis of patients with CLABSI-POA in 3 health systems covering 11 hospitals across Maryland, Washington DC, and Missouri from November 2020 to October 2021. CLABSI-POA was defined using an adaptation of the acute care CLABSI definition. Patient demographics, clinical characteristics, and outcomes were collected via record review. Cox proportional hazard analysis was used to assess factors associated with the all-cause mortality rate within 30 days. RESULTS: A total of 461 patients were identified as having CLABSI-POA. CVCs were most commonly maintained in home infusion therapy (32.8%) or oncology clinics (31.2%). Enterobacterales were the most common etiologic agent (29.2%). Recurrent CLABSIs occurred in a quarter of patients (25%). Eleven percent of patients died during the hospital admission. Among patients with CLABSI-POA, mortality risk increased with age (hazard ratio vs age <20 years by age group: 20-44 years, 11.2 [95% confidence interval, 1.46-86.22]; 45-64 years, 20.88 [2.84-153.58]; ≥65 years, 22.50 [2.98-169.93]) and lack of insurance (2.46 [1.08-5.59]), and it decreased with CVC removal (0.57 [.39-.84]). CONCLUSIONS: CLABSI-POA is associated with significant in-hospital mortality risk. Surveillance is required to understand the burden of CLABSI in the community to identify targets for CLABSI prevention initiatives outside acute care settings.

Home infusion services in Saudi Arabia: Where are we standing?

Diseases management has reached the highest level of complexity and cost in history, worldwide, and in Saudi Arabia in particular, which led to prolonged, unnecessary hospital stays. There have been many recent innovative measures to reduce these issues. One is to provide home infusion services. Hence, this narrative review emphasizes the expected benefits and challenges of such services and the applicability of their implementation in Saudi Arabia. A literature search was conducted via PubMed database, involving all published studies from inception until March 24th, 2023. Many studies showed positive impacts of home infusion on reducing the length of hospital stays, increasing cost-saving, and leading to high patient satisfaction.

Experience in the use of midclavicular catheters: An inception cohort study.

AIMS AND OBJECTIVES: To describe the outcomes of midclavicular catheters related to first insertion success rate, catheter dwell time, rate of catheter survival until the end of the treatment, and complication rates, as well as identify risk factors associated with early catheter removal. BACKGROUND: Midclavicular catheters are peripheral venous catheters that are typically 20-25 cm in length. DESIGN: Inception cohort study. METHODS: We included all the midclavicular lines inserted in patients who met any of the following criteria: (a) difficult venous access; (b) administration of intravenous therapy expected to last between 6 and 30 days with non-irritant (pH=5-9) and/or non-vesicant drugs; or (c) contraindications to central venous catheter placement. The incidence of adverse events was calculated using percentages and episodes per 1,000 catheter days. Univariate and multivariate logistic regression analyses were performed to identify significant risk factors for unexpected catheter removal by calculating odds ratios. Catheter survival was assessed using Cox regression analysis. The STROBE guidelines were followed. RESULTS: Overall, 2,275 midclavicular lines were placed in 1,841 participants. The insertion success rate was 99.4% and the mean catheter dwell time was 21.82 days. The rate of adverse events was .7 per 1,000 catheter days, the most common complications being thrombosis (.39) and catheter-associated bacteraemia (.14). No significant association was found between adverse events and the administration of irritant drugs. The incidence of unexpected removal was 6.7 per 1,000 catheter days. The multivariate analysis showed that both age ≤70 years and home therapy were associated with a lower likelihood of catheter failure. CONCLUSIONS: Midclavicular catheters are associated with a high rate of insertion success and low rates of adverse events and unplanned removal. RELEVANCE TO CLINICAL PRACTICE: Midclavicular lines are a safe alternative for intravenous therapy lasting more than 6 days, even with irritant drugs.

Clinical strategies for optimizing infusion center care through a pandemic.

The national pandemic resulting from the novel coronavirus, COVID-19, has made the delivery of care for patients with cancer a challenge. There are competing risks of mortality from cancer versus serious complications and higher risk of death from COVID-19 in immunocompromised hosts. Furthermore, compounding these concerns is the inadequate supply of personal protective equipment, decreased hospital capacity, and paucity of effective treatments or vaccines to date for COVID-19. Guidance measures and recommendations have been published by national organizations aiming to facilitate the delivery of care in a safe and effective manner, many of which, are permanently adoptable interventions. Given the critical importance to continue chemotherapy, there remains additional interventions to further enhance patient safety while conserving healthcare resources such as adjustments in medication administration, reduction in laboratory or drug monitoring, and home delivery of specialty infusions. In this manuscript, we outline how to implement these actionable interventions of chemotherapy and supportive care delivery to further enhance the current precautionary measures while maintaining safe and effective patient care. Coupled with current published standards, these strategies can help alleviate the numerous challenges associated with this pandemic.

Home-Based Treatment with Immunoglobulins: an Evaluation from the Perspective of Patients and Healthcare Professionals.

PURPOSE: This study aims to evaluate home-based treatment with immunoglobulin (IgG) by assessing and comparing the experiences and perceived value of patients and healthcare professionals, and potential differences in experiences between subcutaneous (SCIg) and intravenous (IVIg) modes of administration. As choices on the location and type of treatment are determined in a shared decision-making process, we evaluated the home-based treatment from the perspectives of both patients and professionals. METHODS: A questionnaire study was conducted among 205 patients, 44 informal caregivers, 43 hospital professionals, and 21 nurses of the Sanquin Home Service (SHS) that provides home treatment with immunoglobulins in the Netherlands. Experiences, perceived benefits, and effects on the patients' quality of life and overall ratings were assessed. RESULTS: Both patients and professionals were predominantly positive about the home treatment, irrespective of the administration mode. The home-based treatment with Ig contributed to the patients' autonomy, participation, and perceived health. Patients and informal caregivers valued the treatment with a global rating of 8.84, and professionals with 8.32 (on a scale from 0 "worst" to 10 "best possible care"). SCIg and IVIg patient groups differed in their experiences regarding the accessibility and communication of the home treatment service. Furthermore, hospital professionals reported lower effects on quality of life than patients themselves. CONCLUSIONS: Home-based treatment with immunoglobulins is highly valued because of its personalized and effective character, meeting the needs and preferences of patients. Nonetheless, patients and professionals do have different perspectives on the value of this type of care.

Impact of Site of Care on Infection Rates Among Patients with Primary Immunodeficiency Diseases Receiving Intravenous Immunoglobulin Therapy.

PURPOSE: Patients with primary immunodeficiency diseases (PIDD) are at increased risk of infection and may require lifelong immunoglobulin G (IgG) replacement. Infection incidence rates were determined for patients with PIDD receiving intravenously administered IgG (IGIV) in a home or hospital outpatient infusion center (HOIC). METHODS: Data were extracted from a large, US-based, employer-sponsored administrative database. Patients were eligible for analysis if they had ≥1 inpatient or emergency room claim or ≥2 outpatient claims with a PIDD diagnosis between January 2002 and March 2013, 12 months of continuous health plan enrollment prior to index date (i.e., first IGIV infusion date), and 6 months of continuous IGIV at the same site of care after the index date. Incidences of pneumonia (bacterial or viral) and bronchitis (all types) within 7 days of IGIV infusion were retrospectively determined and compared between sites of care. RESULTS: A total of 1076 patients were included in the analysis; 51 and 49% received IGIV at home and at an HOIC, respectively. The event/patient-year of pneumonia was significantly lower in patients receiving IGIV at home compared to an outpatient hospital (0.102 vs. 0.216, p = 0.0071). Similarly, the event/patient-year of bronchitis was significantly lower among patients infusing at home compared to an HOIC (0.150 vs. 0.288, p < 0.0001). CONCLUSIONS: PIDD patients experienced incidence rates for pneumonia and bronchitis that were lower for patients receiving home-based IGIV treatment versus HOIC-based IGIV treatment. The lower infection rates in the home setting suggest that infection risk may be an important factor in site of care selection.

Association of overweight and obesity with the use of self and home-based infusion therapy among haemophilic men.

An elevated body mass index (BMI) may make venipuncture more difficult, potentially impacting the use of home infusion (HI) and self-infusion (SI). We sought to determine whether above-normal BMI is associated with decreased use of HI treatment and SI of clotting factor concentrate among haemophilic persons. We analysed data from 10,814 male patients with haemophilia A and B (45% with severe disease) aged 6-79 years enrolled in the Centers for Disease Control and Prevention Universal Data Collection surveillance project between 1998 and 2008. Associations between the use of HI and SI and BMI were evaluated using logistic regression. Fifty per cent of haemophilic men were overweight or obese, similar to rates reported among the general US population by the 2007-2008 National Health and Nutrition Examination Survey [Flegal, KM et al., JAMA 2010;303:235-241;]. Twenty per cent of children and 22% of teens were obese, as were 28% of adults [Ogden, CL et al., JAMA 2010;303:235, 242]. Overall, 70% of the study sample used HI; 44% of those who used HI also used SI. Overweight and obese men were each less likely to use HI than those of normal weight [odds ratio (OR) 0.8; 95% confidence interval (CI) 0.7-1.0 and OR 0.7; 95% CI 0.6-0.8 respectively]. Obese teens and adult men were also less likely to practice SI than teens and adults of normal weight (OR 0.8; 95% CI 0.7-0.9 for each). We conclude that overweight and obese haemophilic men are less likely to use HI and obese men are less likely to use SI than their normal-weight counterparts.

First analysis of 10-year trends in national factor concentrates usage in haemophilia: data from CHARMS, the Canadian Hemophilia Assessment and Resource Management System.

The Canadian Hemophilia Assessment and Resource Management System (CHARMS) tracks factor concentrates (FC) from the sole suppliers, Canadian Blood Services (CBS) and Hema-Quebec (HQ), to hospitals and to patients' homes. Patients FC infusion data are entered into CHARMS at Canadian Hemophilia Treatment Centres (HTCs) then exported to the national database (CentrePoint). From 2000 to 2009, 2260 registered haemophilia A or B patients received FVIII (1,009,097,765 IU) and FIX (272,406,859 IU). Over 91% of FVIII and over 84% of FIX was infused at home. Utilization of FVIII progressively increased; this was accounted for by an increase in the number of patients treated (r = 0.97; P < 0.001), there being a linear relationship between the increase in utilization and the increase in number of patients treated (P < 0.001). There was also a correlation with the annual amount used per patient (r = 0.95; P < 0.001). Utilization of FIX did not increase over time. The highest proportional utilization of both FVIII and FIX was for prophylaxis, and this proportion progressively increased being, in year 10 (2009), 77% and 66% for FVIII and FIX respectively. The proportion used for bleeding remained steady; in year 10 that proportion was 14% for FVIII and 26% for FIX, the use per patient for bleeding decreasing. The HTC-based CHARMS tracking system is essential, in Canada, for analysing indications for infusion, for predicting utilization and planning for future needs.

A Quality Approach to Blinatumomab Delivery in Pediatric Oncology: A Children's Oncology Group Study.

Background: Blinatumomab is a promising immunotherapy agent that has been shown to improve survival outcomes in children diagnosed with relapsed B-lineage acute lymphoblastic leukemia. Expanded use of blinatumomab in the treatment of childhood cancer is expected; however, clinician perspectives regarding administering this agent in healthcare and home settings have not been explored. Method: Semistructured interviews were conducted with clinicians (N = 13) from pediatric institutions across the United States and Canada. Qualitative data were analyzed using a constant comparative analysis three-stage method. Results: Participants were primarily nurses (92%), female (77%), and had greater than 10 years of pediatric oncology experience. The selective code and overarching theme identified was "A quality approach to blinatumomab delivery in pediatric oncology." Clinicians described detailed processes that were created and implemented to promote a common goal of safe blinatumomab administration across the continuum of care. Clinicians shared how they engaged in planning activities and considered a variety of factors prior to and during blinatumomab administration. Clinicians also expressed a need to reflect and evaluate on previous patient experiences to create new or revise existing processes and workflows. Communication was also central to clinicians' work. Clinicians provided recommendations to assist others with blinatumomab administration and offered suggestions for items that could help with implementing future clinical trials containing similar agents. Discussion: Findings suggest nurses are pivotal to establishing processes which support safe administration of immunotherapies, such as blinatumomab, while also considering patient-specific needs and promoting quality of life.

Infusion parameters, safety, and practical guidance for the manual administration of subcutaneous immunoglobulin 20% (Ig20Gly).

Primary immunodeficiency diseases (PIDs), also referred to as inborn errors of immunity, constitute a group of genetic conditions that affect the immune system. The current standard of care for patients with PIDs is lifelong immunoglobulin replacement therapy, delivered by intravenous (IVIG) or subcutaneous (SCIG) infusion. Immune globulin subcutaneous (human) 20% solution stabilized with glycine (Ig20Gly) is indicated as a replacement therapy for PIDs in adults and children of any age in Europe and in patients aged 2 years and above in the USA. Typically, Ig20Gly is administered using an infusion pump; however, delivery of Ig20Gly by manual administration has recently been approved in Europe. Practical recommendations on the use of Ig20Gly manual administration are lacking; this review therefore aims to provide guidance for use of this method of administration. Additionally, we summarize the infusion parameters, safety, patient-reported outcomes, and economic benefits associated with Ig20Gly manual administration. Manual administration of Ig20Gly was shown to permit faster rates of infusion than administration via infusion pump. Patients typically infused at two or fewer infusion sites with manual administration of Ig20Gly. Safety and tolerability profiles were similar for Ig20Gly manual administration and administration by infusion pump. Overall, there were comparable levels of patient satisfaction with manual administration and infusion pump, with patient preference deemed to be a key determinator of success for either method of administration. Economic studies identified cost savings for the healthcare system through manual administration compared with IVIG or SCIG infusion by infusion pump because of the reduced equipment costs and nurse support. For infusion of Ig20Gly by manual administration, a syringe and butterfly needle are used; patients are advised to start infusion at 1-2 mL/min to prevent discomfort. Overall, manual administration of Ig20Gly offers an effective and well-tolerated alternative to administration by infusion pump.

Retrospective study of home antibiotic infusion therapy in elastomeric infusion pumps. / Estudio retrospectivo de la terapia de infusión de antibióticos domiciliaria en bombas de infusión elastoméricas.

OBJECTIVES: To describe the experience of home antibiotic infusion therapy using elastomeric infusion pumps, administered to patients admitted to the Home Hospitalization Unit of a tertiary hospital for three years and to analyse clinical evolution and mortality. METHOD: Retrospective observational study. The medical history of the patients included in the study was reviewed. Information was obtained on personal history, antimicrobial therapy received and clinical evolution. Statistical analysis was performed using SPSS® 19 software. RESULTS: Eighty-one patients were included, 61.7% men, with a mean age of 73.5 ± 17.5 years. The most frequent comorbidities were diabetes mellitus (30.9%) and chronic kidney disease (28.4%). Patients received a mean of 11.9 ± 8.5 days of antibiotic treatment in an elastomeric infusion pump. The main focus of infection was respiratory (27.2%), followed by bacteremia (16%) and skin and soft tissue infections (12.3%). Of the infections, 65.4% were monomicrobial, with Pseudomonas aeruginosa being the main microorganism involved (39.6%). The most commonly used antimicrobial was piperacillin/tazobactam (33.3%). The clinical course was good in 85.2% of the patients, but the mortality rate in the 30 days following the end of treatment was 24.7%. In the univariate analysis, a history of neoplasia in the last 5 years (p = 0.01) and having received fewer days of antibiotic therapy prior to the start of outpatient antimicrobial therapy in infusion pump (p = 0.04) were associated with worse clinical outcome. Age over 80 years was associated with better outcome (p = 0.03). The diagnosis of heart failure was associated with higher mortality (p = 0.026) and patients from surgical services, with lower mortality (p = 0.047). In the multivariate analysis, the presence of neoplasia was associated with unfavorable evolution (p = 0.012) and heart failure with higher mortality (p = 0.027). CONCLUSIONS: Outpatient antimicrobial therapy in elastomeric infusion pumps is an alternative in patients requiring prolonged intravenous treatment, and age is not a conditioning factor for inclusion in these programs. However, the presence of certain comorbidities can negatively affect the clinical course and mortality of patients.

Patient safety outcomes for continuous infusion vancomycin as outpatient parenteral antimicrobial therapy.

BACKGROUND: Administration of vancomycin as a continuous infusion has been associated with reduced nephrotoxicity. Given limited published experience with continuous infusion vancomycin in outpatient parenteral antimicrobial therapy (OPAT) programs, we reviewed outcomes from our center. METHODS: This was a retrospective, single-center study of adult patients receiving vancomycin OPAT as continuous or intermittent infusion for an intended treatment duration of at least 7 days. The primary outcome was time to nephrotoxicity with continuous versus intermittent infusion vancomycin while on OPAT; additional outcomes included time to any vancomycin-associated adverse event, time to 60-day death or readmission, and time to 60-day emergency department encounter. Proportional hazards modeling was used to identify variables independently associated with outcomes, as well as assess the strength of association of continuous infusion with each outcome. RESULTS: Four-hundred ninety-two patients were included: 118 treated with continuous and 374 with intermittent vancomycin infusion. Continuous infusion was not associated with lower rates of nephrotoxicity compared to intermittent infusion (adjusted hazard ratio (aHR) 0.72, 95% CI: 0.35-1.50). There were no advantages of continuous over intermittent infusion in the rates of any adverse event (aHR 0.93, 95% CI: 0.56-1.53), 60-day death or readmission (aHR 1.04, 95% CI: 0.68-1.61), or 60-day emergency department encounter (aHR 1.17, 95% CI: 0.68-1.99). Vancomycin area under the concentration-time curve (AUC) at discharge was the only modifiable factor identified that was independently associated with patient safety outcomes. CONCLUSION: There was no appreciable benefit of continuous infusion vancomycin on outpatient safety outcomes. AUC-centered dosing approaches warrant further investigation as strategies to improve vancomycin safety in OPAT programs.

An evaluation of risk factors for readmission in patients receiving outpatient parenteral antimicrobial therapy.

Background: Outpatient parenteral antimicrobial therapy (OPAT), when required, is beneficial to patients and healthcare systems by reducing hospital length-of-stay, providing cost savings, and improving patient satisfaction. Objectives: The purpose of this study is to determine readmission rates and associated risk factors in patients receiving OPAT at home. Methods: This retrospective study included hospitalized patients 15 years and older who were discharged on intravenous antimicrobial therapy via OPAT at home between January 2018 and December 2019. Patients receiving antimicrobials at a skilled nursing facility, long-term acute care, or dialysis center, and those who began OPAT at home directly from the outpatient setting were excluded. The primary outcome of this study was all-cause 30-day readmission rate. Secondary outcomes included 90-day readmission rate, rates of complications related to OPAT, emergency department visits during OPAT, and predictors of all-cause 30-day readmission through a logistic regression analysis. Results: Two hundred individual patients were included in the analysis; 60% were male and the mean age was 49 years. The most common indications for OPAT at home were bone and joint infection (52%) and bacteremia (26%). Forty patients (20%) experienced an unplanned, all-cause 30-day readmission, with a total of 48 readmission events. Of the 40 patients who were readmitted within 30 days, 20 (50%) were due to non-OPAT related reasons. Sixty patients (30%) experienced an OPAT-related complication, and chronic kidney disease was found to be an independent predictor of readmission (OR: 2.8, 95% CI: 1.0-7.6). Conclusions: Patients receiving OPAT at home are at increased risk for early hospital readmission, but it is often due to reasons not associated with OPAT. Patients with chronic kidney disease beginning OPAT at home should be closely monitored after discharge.

Navigating Access and Optimizing Medication Infusions in an Academic Medical Center: A Quality Improvement Study.

(1) Background: The rising prices of medical infusions have resulted in the increased utilization of policies for payors to manage costs. These policies can be disruptive to the continuity of care, and health systems should develop a systematic strategy to address market changes and prevent patient leakage. (2) Methods: A quality improvement study was conducted by an interdisciplinary workstream to assess the current state of infusion services in an academic medical center in the Midwest and to provide recommendations for immediate access improvement and long-term system planning. An organizational assessment of the value stream was completed, which analyzed the available infusion capacity, billing strategy, patient mix/volumes, payor mix, staffing levels, and current policies. The interventions implemented after developing the infusion system strategy were triaging patients to the appropriate site of care to increase infusion capacity and eliminating paper orders in one of the health system's Infusion Centers. (3) Results: Patients receiving medical infusions for oncologic conditions warrant unique considerations in evaluating the Infusion Center's efficiency due to the infusion regimen's length, complexity, and tolerability. The management of the payor site of care also poses a challenge for health systems to triage patients effectively without fragmenting care. (4) Conclusions: An organizational strategy around infusion services must include broad stakeholder representation to address the clinical, operational, and financial challenges to provide timely care to patients.

Adverse Events and Compliance Among Inflammatory Bowel Disease Patients Treated With Home- vs Office-Based Biologic Infusions.

BACKGROUND: Biologic medications are a common therapy for those with inflammatory bowel disease (IBD). There are limited data on the outcomes of home-based biologic infusions for patients with IBD. The aim of this study was to compare the safety and efficacy of biologic infusions for IBD patients who receive either home- or office-based administration. METHODS: Patients receiving infliximab or vedolizumab were analyzed retrospectively over a period of 152 weeks. Survival free of major adverse events including delayed infusion reaction, steroid initiation, drug discontinuation, or IBD-related emergency department visits, admission, and surgery were compared using a Kaplan-Meier curve. Individual adverse events, infusion-.related quality measures, and markers of patient adherence were analyzed. RESULTS: Adverse event-free survival was greater among those receiving home-based infusion (n = 154) compared with office-based infusion (n = 133). The office infusion cohort had higher rates of delayed infusion reactions (4 vs 0), IBD-related surgery (6 vs 0), and drug discontinuation (44 vs 35); this was a sicker cohort of patients compared with those in the home infusion group. Home infusion patients were less likely to receive correct weight-based dosing for infliximab (71.7% vs 89.3%), obtain labs for drug monitoring (53.2% vs 71.4%), and adhere to routine clinic visits (37.9% vs 58.1%). CONCLUSIONS: The home-based infusion of biologics for IBD appears safe with lower rates of major adverse events compared with office-based infusions. However, those receiving home infusion were less likely to receive correct weight-based dosing for infliximab and were poorly adherent to routine follow-up.

There are higher rates of adverse events among inflammatory bowel disease patients infused with biologics in the office rather than at home. The quality of care delivered and patient adherence to follow-up is reduced among those receiving home infusions.

Switching from intravenous vancomycin to oral antibiotics reduces adverse events in a retrospective cohort of outpatients with orthopedic infections.

INTRODUCTION: Vancomycin is frequently used for prolonged courses in treating osteoarticular infections despite a high rate of adverse drug events (ADE). The objective of this study was to evaluate the safety and effectiveness of transitioning to oral therapy compared to continuing parenteral vancomycin in patients with orthopedic infections. METHODS: We conducted a single-center, retrospective cohort study of patients with orthopedic infections discharged on parenteral vancomycin with a planned duration of at least 4 weeks. We compared rates of ADE while on vancomycin to rates of ADE after switching to an oral regimen. As a secondary analysis, we compared unplanned hospital readmission within 60 days and treatment failure at 1 year between patients who were transitioned to oral antibiotics within 4 weeks of vancomycin initiation and those that were not. RESULTS: Two hundred twenty-eight patients met the inclusion criteria. Vancomycin was associated with significantly greater toxicity compared to oral regimens. Fifty-one patients had an adverse event while on vancomycin (5.87 ADE per 1000 patient-days) while 9 patients had an adverse event on oral therapy (1.49 ADE per 1000 patient-days) (Rate difference 4.39 per 1000 patient days, 95% CI: 2.52 to 6.26 events per 1000 patient-days). In proportional hazards analysis, transition to an oral antibiotic regimen was independently associated with a lower rate of ADE (aHR 0.12, 95% CI: 0.02-0.86). Forty-one patients (18%) were transitioned to oral therapy within 4 weeks; these patients did not have an increased rate of unplanned readmission (12.2% vs 17.1%) or treatment failure (17.1% vs 21.9%). CONCLUSIONS: Patients transitioned to oral therapy within 4 weeks of discharge had significantly fewer adverse events and similar incidences of 1-year treatment failure compared to patients maintained on parenteral vancomycin. Substituting oral antibiotics for parenteral vancomycin is a potential strategy to minimize vancomycin toxicity during the treatment of orthopedic infections.

The patients` perspective on home-based infusion: A longitudinal observational study in the German healthcare setting for patients with lysosomal storage disorders treated with enzyme replacement therapy.

Background: Lysosomal storage diseases (LSDs), metabolic disorders resulting in build-up of endogenous waste and progressive organ damage, can be treated with intravenous enzyme replacement therapy (ERT). ERT can be administered either in specialized clinics, at a physician's office or in the home care setting. Legislative goals in Germany strive to shift to more outpatient care while maintaining treatment objectives. This study investigates the patient perspective on home-based ERT in terms of acceptance, safety, and treatment satisfaction in LSD patients. Methods: This was a longitudinal observational study, carried out under real-world conditions in patients' home environment, covering 30 months from January 2019 to June 2021. Patients with LSDs who were deemed suitable for home-based ERT by their physicians were recruited to the study. Patients were interviewed before the start of the first home-based ERT and then at regular intervals thereafter using standardized questionnaires. Results: Data from 30 patients were analyzed: 18 with Fabry disease, 5 with Gaucher disease, 6 with Pompe disease and 1 with Mucopolysaccharidosis type I (MPS I). Age ranged from 8 to 77 years (mean age 40). The reported average waiting time prior to infusion of more than half an hour decreased from 30% of the patients affected at baseline to 5% across all follow-up time points. All patients felt adequately informed about home-based ERT throughout follow-ups and reported that they would choose home-based ERT again. At almost each time point, patients indicated that home-based ERT had improved their ability to cope with the disease. All but one patient indicated feeling safe at each follow-up time point. Compared to 36.7% at baseline, only 6.9% of patients reported a need for improvement in their care after 6 months of home-based ERT. Mean treatment satisfaction increased by approximately 1.6 scale points after 6 months of home-based ERT compared to baseline, and by another 0.2 scale points after 18 months. In terms of quality of care, all but one patient rated home-based ERT as an equivalent alternative throughout follow-ups. Patients would recommend home-based ERT to other suitable LSD-patients. Conclusion: Home-based ERT increases patients' treatment satisfaction, and patients perceive the quality of care as an equivalent alternative, compared to ERT in a center, clinic, or at a physician's office.

Real-World Experiences with Taliglucerase Alfa Home Infusions for Patients with Gaucher Disease: A Global Cohort Study.

Taliglucerase alfa is an enzyme replacement therapy approved for Gaucher disease. We assessed the duration/compliance/safety of such home infusions in commercial use in four countries where home infusion programs are available. The treatment duration/compliance study included 173 patients (Israel, 58; US, 61; Brazil, 48; Australia, 6) who received ≥1 taliglucerase alfa home infusion through 6/2021. The median age at home therapy initiation was 38 (range, 2-87) years; 58% were females. The median treatment duration (at home) was 2.7 (range, 0.04-9.0) years. The annual compliance rate was stable (≥95%) throughout the study period. A search of the Pfizer global safety database (through 6/2021), identified 19 adverse events (AEs) as related to "definite home use" and 14 to "possible home use" of taliglucerase alfa; 42.4% of these AEs were serious; none were fatal. Twelve serious AEs in five separate case reports were considered treatment related: one case of chest discomfort/pain and hypertension and one case of erythema associated with a toe blister, for which causality could not be excluded; pain in extremity; projectile vomiting and chills, alongside excessive eye blinking; and an infusion-related AE (pruritus). In conclusion, this real-life global study demonstrated that taliglucerase alfa home infusions are safe with high compliance rates.

Positive Impact of Home ERT for Mucopolysaccharidoses and Pompe Disease: The Lesson Learnt from the COVID-19 Pandemic.

OBJECTIVE: Patients with Lysosomal disorders (LSDs) are treated with regular infusions of enzyme replacement therapy (ERT). During the COVID-19 pandemic, home treatment was permitted. This study aimed at monitoring the patients' compliance with home therapy and its effects on physical, psychological, and relational issues. Moreover, we also tested the possible impact of home therapy on familial relationships and contacts with the referral hospital. MATERIALS AND METHODS: Thirteen patients with Pompe disease (N = 8) and MPS (N = 5) were tested through an online questionnaire designed to assess their level of appreciation and satisfaction with home therapy and their feelings about the referral centre and psychological support provided. RESULTS: Most of the patients (84%) stressed the positive impact of home therapy. All patients described a significant reduction in stressful conditions associated with the need to attend the hospital every week or two. CONCLUSIONS: Home ERT leads to a clear improvement in "daily life skills", as represented in our by sample by positive feelings, better emotional self-control, and an increased ability to understand the feelings of relatives. Our data underline the paramount positive effect home ERT has on both patients and their families.
