Hospital Prices for Physician-Administered Drugs for Patients with Private Insurance.

BACKGROUND: Hospitals can leverage their position between the ultimate buyers and sellers of drugs to retain a substantial share of insurer pharmaceutical expenditures. METHODS: In this study, we used 2020-2021 national Blue Cross Blue Shield claims data regarding patients in the United States who had drug-infusion visits for oncologic conditions, inflammatory conditions, or blood-cell deficiency disorders. Markups of the reimbursement prices were measured in terms of amounts paid by Blue Cross Blue Shield plans to hospitals and physician practices relative to the amounts paid by these providers to drug manufacturers. Acquisition-price reductions in hospital payments to drug manufacturers were measured in terms of discounts under the federal 340B Drug Pricing Program. We estimated the percentage of Blue Cross Blue Shield drug spending that was received by drug manufacturers and the percentage retained by provider organizations. RESULTS: The study included 404,443 patients in the United States who had 4,727,189 drug-infusion visits. The median price markup (defined as the ratio of the reimbursement price to the acquisition price) for hospitals eligible for 340B discounts was 3.08 (interquartile range, 1.87 to 6.38). After adjustment for drug, patient, and geographic factors, price markups at hospitals eligible for 340B discounts were 6.59 times (95% confidence interval [CI], 6.02 to 7.16) as high as those in independent physician practices, and price markups at noneligible hospitals were 4.34 times (95% CI, 3.77 to 4.90) as high as those in physician practices. Hospitals eligible for 340B discounts retained 64.3% of insurer drug expenditures, whereas hospitals not eligible for 340B discounts retained 44.8% and independent physician practices retained 19.1%. CONCLUSIONS: This study showed that hospitals imposed large price markups and retained a substantial share of total insurer spending on physician-administered drugs for patients with private insurance. The effects were especially large for hospitals eligible for discounts under the federal 340B Drug Pricing Program on acquisition costs paid to manufacturers.

Quantifying the Time to Administer Outpatient Parenteral Antimicrobial Therapy: A Missed Opportunity to Compensate for the Value of Infectious Diseases.

Outpatient parenteral antimicrobial therapy (OPAT) relies on substantial uncompensated provider time. In this study of a large academic OPAT program, the median amount of unbilled OPAT management time was 27 minutes per week, per OPAT course. These data should inform benchmarks in pursuing novel payment approaches for OPAT.

Making a case for outpatient parenteral antimicrobial therapy (OPAT).

In the wake of the COVID-19 pandemic, and its negative impact on both acute and elective care and decline in available inpatient resources, there is an imperative to maximize safe and effective alternatives to inpatient hospital care. Properly governed outpatient parenteral antimicrobial therapy (OPAT) services embed the principles of antimicrobial stewardship (AMS) (including use of early oral therapy) and support admission avoidance and early discharge for a growing range of patient groups with complex infections through well-organized multidisciplinary team working. Expansion of OPAT aligns with the UK's national strategy to deliver care closer to home and cost-effectively maximize use of inpatient resources. OPAT serves as an exemplar to other ambulatory services and presents opportunities for developing and assuring AMS strategies within the rapidly developing hospital-at-home and virtual ward environments.

The effect of an initial catheter ablation with an adjunctive ethanol infusion into the vein of Marshall on persistent atrial fibrillation.

INTRODUCTION: Some previous studies have reported that a first-step ethanol infusion into the vein of Marshall (EIVOM) with touch-up radiofrequency (RF) ablation can facilitate mitral isthmus (MI) block and improves the ablation outcomes in persistent atrial fibrillation (PeAF) patients. However, the effect of an initial RF ablation with an adjunctive EIVOM has not been fully investigated. METHODS: This study enrolled 233 PeAF patients undergoing pulmonary vein isolation and linear ablation including an MI, roof line, and cavotricuspid isthmus ablation. An EIVOM was performed when endocardial ablation with or without coronary sinus ablation failed to create MI block. RESULTS: Bidirectional MI block was achieved in 224 patients (96.1%). Among them, MI block was obtained by only RF ablation in 174/224 patients (77.7%) (RF group) and an adjunctive EIVOM was needed in 50/224 (22.3%) (EIVOM group). During the follow-up, 113 (64.9%) RF group patients were free from AF/atrial tachycardia compared to 41 (82.0%) EIVOM group patients (log-rank p = .045). In a multivariate Cox regression analysis, an adjunctive EIVOM was associated with a lower recurrence rate (hazard ratio = 0.39, 95% confidence interval = 0.17-0.78, p = .006). CONCLUSION: An initial RF ablation with an adjunctive EIVOM strategy improved MI ablation's acute success rate and was associated with better clinical outcomes.

Intraperitoneal chemotherapy for peritoneal metastases of gastric origin: a systematic review and meta-analysis.

BACKGROUND: Gastric cancer with peritoneal metastases is associated with a dismal prognosis. Normothermic catheter-based intraperitoneal chemotherapy and normothermic pressurized intraperitoneal aerosol chemotherapy (PIPAC) are methods to deliver chemotherapy intraperitoneally leading to higher intraperitoneal concentrations of cytotoxic drugs compared to intravenous administration. We reviewed the effectiveness and safety of different methods of palliative intraperitoneal chemotherapy. METHODS: Embase, MEDLINE, Web of Science and Cochrane were searched for articles studying the use of repeated administration of palliative intraperitoneal chemotherapy in patients with gastric cancer and peritoneal metastases, published up to January 2024. The primary outcome was overall survival. RESULTS: Twenty-three studies were included, representing a total of 999 patients. The pooled median overall survival was 14.5 months. The pooled hazard ratio of the two RCTs using intraperitoneal paclitaxel and docetaxel favoured the intraperitoneal chemotherapy arm. The median overall survival of intraperitoneal paclitaxel, intraperitoneal docetaxel and PIPAC with cisplatin and doxorubicin were respectively 18.4 months, 13.2 months and 9.0 months. All treatment methods had a relatively safe toxicity profile. Conversion surgery after completion of intraperitoneal therapy was performed in 16% of the patients. CONCLUSIONS: Repeated intraperitoneal chemotherapy, regardless of method of administration, is safe for patients with gastric cancer and peritoneal metastases. Conversion surgery after completion of the intraperitoneal chemotherapy is possible in a subset of patients.

Outpatient parenteral antimicrobial therapy (OPAT) in Germany: insights and clinical outcomes from the K-APAT cohort study.

PURPOSE: Outpatient parenteral antimicrobial therapy (OPAT) offers several key advantages, including enhanced patient quality of life, reduced healthcare costs, and a potential reduction of nosocomial infections. It is acknowledged for its safety and effectiveness. This study provides the first systematic clinical data for Germany, where OPAT has not yet been widely adopted. The aim is to establish a foundational reference point for further research and integration of OPAT into the German healthcare system. METHODS: This prospective observational study descriptively analyses data obtained from a cohort of patients receiving OPAT. Both in- and outpatients from all medical specialties could be recruited. Patients administered the anti-infective medications themselves at home using elastomeric pumps. RESULTS: 77 patients received OPAT, with a median duration of 15 days and saving 1782 inpatient days. The most frequently treated entities were orthopaedic infections (n = 20, 26%), S. aureus bloodstream infection (n = 16, 21%) and infectious endocarditis (n = 11, 14%). The most frequently applied drugs were flucloxacillin (n = 18, 23%), penicillin G (n = 13, 17%) and ceftriaxone (n = 10; 13%). Only 5% of patients (n = 4) reported to have missed more than one outpatient dose (max. 3 per patient). Only one catheter-related adverse event required medical intervention, and there were no catheter-related infections. CONCLUSION: The study demonstrates that OPAT can be safely conducted in Germany. In preparation for its broader implementation, crucial next steps include creating medical guidelines, fostering interdisciplinary and inter-sectoral communication, as well as creating financial and structural regulations that facilitate and encourage the adoption of OPAT.

Extended physicochemical stability of cetuximab in opened vials and infusion bags when stored at 4°C and 25°C.

INTRODUCTION: This study aimed to determine the stability of cetuximab: (1) under "in-use" conditions after dilution to 1 mg/mL in 0.9% sodium chloride in polyolefin bags and (2) as an undiluted solution (5 mg/mL) repackaged in polypropylene bags or kept in the vial after opening. METHODS: Ready-to-use 500 mg/100 mL vials of cetuximab solution were diluted to 1 mg/mL in 100 mL bags of 0.9% sodium chloride or repackaged as a 5 mg/mL solution into empty 100 mL bags. Bags and vials were stored at 4°C for 90 days and 25°C for 3 days. A syringe sample of 7 mL was taken from each bag for the initial determinations. The sampled bags were weighed to determine their initial weight and placed under the planned storage conditions. The physicochemical stability of cetuximab was estimated using validated methods. RESULTS: No changes in turbidity, no protein loss, and no changes in cetuximab tertiary structure were observed after 30 days of storage or when subjected to a temperature excursion of 3 days at 25°C and when stored at 4°C for up to 90 days, regardless of the concentrations and batches. The colligative parameters did not change under any of the tested conditions. No evidence of microbial growth was found in bags after 90 days of storage at 4°C. CONCLUSION: These results support the extended in-use shelf-life of cetuximab vials and bags, which can be cost-effective for healthcare providers.

Exploring patients' perspectives: a mixed methods study on Outpatient Parenteral Antimicrobial Therapy (OPAT) experiences.

BACKGROUND: Outpatient Parenteral Antimicrobial Therapy (OPAT), an alternative to inpatient intravenous antibiotic therapy, has shown benefits in international studies such as increased patient satisfaction. Because OPAT has been used only sporadically in Germany so far, no structured results on patients' experiences and concerns regarding OPAT have yet been available. This study therefore aims to explore the experiences of OPAT patients in a pilot region in Germany. METHODS: This is an observational study in a German pilot region, including a survey of 58 patients on their experiences with OPAT, and in-depth interviews with 12 patients (explanatory-sequential mixed-methods design). RESULTS: Patients reported that they were satisfied with OPAT. That a hospital discharge was possible and anti-infective therapy could be continued in the home environment was rated as being particularly positive. In the beginning, many patients in the interviews were unsure about being able to administer the antibiotic therapy at home on their own. However, healthcare providers (doctors and pharmacy service provider staff) were able to allay these concerns. Patients appreciated regular contact with care providers. There were suggestions for improvement, particularly concerning the organization of the weekly check-up appointments and the provision of information about OPAT. CONCLUSIONS: Patients were generally satisfied with OPAT. However, the treatment structures in Germany still need to be expanded to ensure comprehensive and high-quality OPAT care.

Effect of intraperitoneal infusion of ropivacaine combined with dexmedetomidine in patients undergoing total laparoscopic hysterectomy: a single-center randomized double-blinded controlled trial.

PURPOSE: To investigate the effect of intraperitoneal infusion of ropivacaine combined with dexmedetomidine and ropivacaine alone on the quality of postoperative recovery of patients undergoing total laparoscopic hysterectomy (TLH). METHODS: Female patients scheduled to undergo a TLH under general anesthesia at Fujian Maternity and Child Health Hospital were included. Before the end of pneumoperitoneum, patients were laparoscopically administered an intraperitoneal infusion of 0.25% ropivacaine 40 ml (R group) or 0.25% ropivacaine combined with 1 µg/kg dexmedetomidine 40 ml (RD group). The primary outcome was QoR-40, which was assessed before surgery and 24 h after surgery. Secondary outcomes included postoperative NRS scores, postoperative anesthetic dosage, the time to ambulation, urinary catheter removal, and anal exhaust. The incidence of dizziness, nausea, and vomiting was also analyzed. RESULTS: A total of 109 women were recruited. The RD group had higher QoR scores than the R group at 24 h after surgery (p < 0.05). Compared with the R group, NRS scores in the RD group decreased at 2, 6, 12, and 24 h after surgery (all p < 0.05). In the RD group, the time to the first dosage of postoperative opioid was longer and the cumulative and effective times of PCA compression were less than those in the R group (all p < 0.05). Simultaneously, the time to ambulation (p = 0.033), anal exhaust (p = 0.002), and urethral catheter removal (p = 0.018) was shortened in the RD group. The RD group had a lower incidence of dizziness, nausea, and vomiting (p < 0.05). CONCLUSION: Intraperitoneal infusion of ropivacaine combined with dexmedetomidine improved the quality of recovery in patients undergoing TLH.

Real-world experience of therapeutic drug monitoring and PK/PD achievement of ceftaroline administered by different infusion regimens in patients with confirmed infections caused by Gram-positive bacteria.

BACKGROUND: Ceftaroline is a novel cephalosporin active against MDR Gram-positive (GP) bacteria. For ß-lactam antibiotics, such as ceftaroline, prolonged infusions and therapeutic drug monitoring (TDM) are used for dosage optimization based on their pharmacokinetics/pharmacodynamics (PK/PD). OBJECTIVES: To describe our experience with TDM and PK/PD target attainment of ceftaroline administered by intermittent and prolonged infusion in a cohort of patients with MDR-GP bacterial infections. METHODS: Patients treated with ceftaroline administered by continuous (24 h), extended (3 h/6 h) and intermittent infusion (1 h) and undergoing TDM of plasma concentrations were included. A 100%fT>4×MIC was the pre-specified PK/PD target and 100%fT>10×MIC was considered overexposure. Dose recommendations were made based on TDM results and each patient's clinical condition. RESULTS: Twelve patients [83.3% male, median age of 73 (38-83) years] were included. Nine patients (75%) achieved 100%fT>4×MIC, all under prolonged infusions. In one patient, the 100%fT was >10×MIC but no toxicity was observed. Based on TDM results, initial doses were recommended to be maintained in eight patients, decreased in three and increased in one. CONCLUSIONS: The administration of ceftaroline by prolonged infusion together with TDM may be a useful strategy for achieving the desired PK/PD target in these patients. However, more studies evaluating the relationship between PK/PD attainment and clinical outcomes are needed.

Co-administration of Intravenous Drugs: Rapidly Troubleshooting the Solid Form Composition of a Precipitate in a Multi-drug Mixture Using On-Site Raman Spectroscopy.

Intravenous drugs are often co-administrated in the same intravenous catheter line due to which compatibility issues, such as complex precipitation processes in the catheter line, may occur. A well-known example that led to several neonatal deaths is the precipitation due to co-administration of ceftriaxone- and calcium-containing solutions. The current study is exploring the applicability of Raman spectroscopy for testing intravenous drug compatibility in hospital settings. The precipitation of ceftriaxone calcium was used as a model system and explored in several multi-drug mixtures containing both structurally similar and clinically relevant drugs for co-infusion. Equal molar concentrations of solutions containing ceftriaxone and calcium chloride dihydrate were mixed with solutions of cefotaxime, ampicillin, paracetamol, and metoclopramide. The precipitate formed was collected as an "unknown" material, dried, and analyzed. Several solid-state analytical methods, including X-ray powder diffraction, Raman spectroscopy, and thermogravimetric analysis, were used to characterize the precipitate. Raman microscopy was used to investigate the identity of single sub-visual particles precipitated from a mixture of ceftriaxone, cefotaxime, and calcium chloride. X-ray powder diffraction suggested that the precipitate was partially crystalline; however, the identity of the solid form of the precipitate could not be confirmed with this standard method. Raman spectroscopy combined with multi-variate analyses (principal component analysis and soft independent modelling class analogy) enabled the correct detection and identification of the precipitate as ceftriaxone calcium. Raman microscopy enabled the identification of ceftriaxone calcium single particles of sub-visual size (around 25 µm), which is in the size range that may occlude capillaries. This study indicates that Raman spectroscopy is a promising approach for supporting clinical decisions and especially for compatibility assessments of drug infusions in hospital settings.

Practical use of apomorphine infusion in Parkinson's disease: lessons from the TOLEDO study and clinical experience.

Subcutaneous apomorphine infusion is a device-aided therapy for Parkinson's disease that can be considered when motor fluctuations become persistent and are no longer adequately controlled by oral/transdermal medication. Apomorphine infusion is less invasive than enteral levodopa, deep brain stimulation or focused ultrasound, and is often indicated even when neurosurgical approaches are contraindicated. This article aims to provide practical guidance for doctors and nurses initiating and treating patients with apomorphine infusion, and is based on both trial data and clinical experience from movement disorders specialists. A post hoc analysis of data from the TOLEDO randomized clinical trial of apomorphine infusion was conducted along with an analysis of 'real world' experience from 13 movement disorders specialists using a questionnaire that focused on starting patients on apomorphine infusion. Practical guidelines for starting treatment with apomorphine infusion are provided taking into consideration the regional disparities in healthcare. Apomorphine infusion is straightforward to administer but to be successful it requires concordance from the patient and family, and clinical support from an experienced team of doctors and nurses, particularly in the early months of treatment.

Physicochemical stability of PF-06439535 (bevacizumab-bvzr; Zirabev®), a bevacizumab biosimilar, under extended in-use conditions.

INTRODUCTION: PF-06439535 (bevacizumab-bvzr; Zirabev®) is a bevacizumab biosimilar. The stability profile and functional activity of PF-06439535 after dilution for intravenous infusion was evaluated following extended storage conditions. METHODS: PF-06439535 drug product was diluted in 0.9% sodium chloride to produce final concentrations of 1.4 and 16.5 mg/mL of PF-06439535, representing clinically relevant low and high doses for intravenous infusion. Three drug product lots and three infusion bag types (polyolefin, ethylene vinyl acetate, and polyvinyl chloride) were tested. To simulate the potential preparation and administration conditions encountered in a clinical setting, prepared drug solutions were initially stored at 25 ± 5°C for 24 ± 2 h, and then at 5 ± 3°C for up to 6 weeks. Extended storage was followed by storage at 25 ± 5°C for 24 ± 2 h before testing. Physicochemical and biological stability were evaluated according to visual characteristics and pH, protein concentration, particulate content, the proportions of molecular weight variants and charge variants, and relative potency. A wide range of analytical techniques optimized for PF-06439535 assessment were employed, such as size-exclusion chromatography, non-reducing sodium dodecyl sulfate capillary electrophoresis, cation-exchange chromatography, far-UV circular dichroism spectroscopy, differential scanning calorimetry, and an in vitro cell-based bioassay. RESULTS: For all concentrations, drug product lots, infusion bag types, and time points tested, there were no significant changes in protein concentration and no notable differences in visual characteristics (color, clarity, and visible particulates). The abundance of molecular weight variants and charge variants remained stable over the 6-week study period. There were no stability concerns with regard to sub-visible particles. There were no significant changes in primary, secondary, or tertiary structure. Finally, the in vitro relative potency of PF-06439535 was maintained throughout the study period. CONCLUSIONS: The stability and biological activity of PF-06439535 was maintained after dilution and storage for up to 6 weeks at 2-8°C, demonstrating the integrity of diluted PF-06439535 under extended in-use conditions.

Effect of ritodrine hydrochloride infusion on fetal movement with the use of a fetal movement acceleration measurement recorder (FMAM recorder).

AIM: To investigate the effect of ritodrine hydrochloride infusion on fetal movement. METHOD: We gathered 20 pregnant women who received ritodrine hydrochloride infusion as the treated group, and 147 pregnant women who did not as the control group. All women recorded gross fetal movement with the fetal movement acceleration measurement recorder after 28 gestational weeks. The record was divided into epochs of 10 s, and the ratio of movement-positive epochs to all epochs was calculated as the fetal movement index. Furthermore, the mean duration and the mean number per hour of no-fetal movement period, where the fetus did not move for 5 min or more, were calculated as the indexes of no-fetal movement. All indexes were compared between the two groups at 28-31 and 32-35 gestational weeks. RESULTS: The fetal movement indexes (%) were 17.29 ± 7.46 (mean ± SD) in the control group and 13.65 ± 7.13 in the treated group at 28-31 weeks (p = 0.139). At 32-35 weeks, they were 14.55 ± 6.43 and 18.50 ± 5.33, respectively (p = 0.03). Similarly, the no-fetal movement indexes (min, times/h) were 15.03 ± 10.99 and 1.61 ± 0.88, and 18.70 ± 15.80 and 1.75 ± 0.96 (p = 0.824, and 0.673) at 28-31 weeks. At 32-35 weeks, they were 18.13 ± 10.88 and 1.95 ± 0.97, and 9.20 ± 5.51 and 1.14 ± 0.71, respectively (p = 0.003, and 0.003). CONCLUSION: Ritodrine hydrochloride infusion increased the fetal movement and decreased the no-fetal movement period at 32-35 weeks.

Neonatal Survival After Serial Amnioinfusions for Bilateral Renal Agenesis: The Renal Anhydramnios Fetal Therapy Trial.

Importance: Early anhydramnios during pregnancy, resulting from fetal bilateral renal agenesis, causes lethal pulmonary hypoplasia in neonates. Restoring amniotic fluid via serial amnioinfusions may promote lung development, enabling survival. Objective: To assess neonatal outcomes of serial amnioinfusions initiated before 26 weeks' gestation to mitigate lethal pulmonary hypoplasia. Design, Setting, and Participants: Prospective, nonrandomized clinical trial conducted at 9 US fetal therapy centers between December 2018 and July 2022. Outcomes are reported for 21 maternal-fetal pairs with confirmed anhydramnios due to isolated fetal bilateral renal agenesis without other identified congenital anomalies. Exposure: Enrolled participants initiated ultrasound-guided percutaneous amnioinfusions of isotonic fluid before 26 weeks' gestation, with frequency of infusions individualized to maintain normal amniotic fluid levels for gestational age. Main Outcomes and Measures: The primary end point was postnatal infant survival to 14 days of life or longer with dialysis access placement. Results: The trial was stopped early based on an interim analysis of 18 maternal-fetal pairs given concern about neonatal morbidity and mortality beyond the primary end point despite demonstration of the efficacy of the intervention. There were 17 live births (94%), with a median gestational age at delivery of 32 weeks, 4 days (IQR, 32-34 weeks). All participants delivered prior to 37 weeks' gestation. The primary outcome was achieved in 14 (82%) of 17 live-born infants (95% CI, 44%-99%). Factors associated with survival to the primary outcome included a higher number of amnioinfusions (P = .01), gestational age greater than 32 weeks (P = .005), and higher birth weight (P = .03). Only 6 (35%) of the 17 neonates born alive survived to hospital discharge while receiving peritoneal dialysis at a median age of 24 weeks of life (range, 12-32 weeks). Conclusions and Relevance: Serial amnioinfusions mitigated lethal pulmonary hypoplasia but were associated with preterm delivery. The lower rate of survival to discharge highlights the additional mortality burden independent of lung function. Additional long-term data are needed to fully characterize the outcomes in surviving neonates and assess the morbidity and mortality burden.

Elastomeric, fillable infusion pumps: an overview for clinical practice.

Due to advances in elastomeric pump technology, there are now devices available that can be filled with intravenous (IV) therapy at the bed or chair side. These devices are safe, reliable and enable the patient to be mobile when having their infusion. The Surefuser™+ elastomeric infusion pump is available in multiple configurations and allows patients to remain independent and receive IV therapy infusions in their own homes. The pump can also be used in the acute healthcare setting where traditional electronic infusion pumps may not be available. This article provides an overview of the Surefuser+ elastomeric infusion pump, its features and mode of action and how it can be used in clinical practice.

Intravenous Local Anesthetic Compared With Intraperitoneal Local Anesthetic in Laparoscopic Colectomy: A Double-blind Randomized Controlled Trial.

INTRODUCTION: Controlling perioperative pain is essential to improving patient experience and satisfaction following surgery. Traditionally opioids have been frequently utilized for postoperative analgesia. Although they are effective at controlling pain, they are associated with adverse effects, including postoperative nausea, vomiting, ileus, and long-term opioid dependency.Following laparoscopic colectomy, the use of intravenous or intraperitoneal infusions of lidocaine (IVL, IPL) are promising emerging analgesic options. Although both techniques are promising, there have been no direct, prospective randomized comparisons in patients undergoing laparoscopic colon resection. The purpose of this study was to compare IPL with IVL. METHODS: Double-blinded, randomized controlled trial of patients undergoing laparoscopic colonic resection. The 2 groups received equal doses of either IPL or IVL which commenced intra-operatively with a bolus followed by a continuous infusion for 3 days postoperatively. Patients were cared for through a standardized enhanced recovery after surgery program. The primary outcome was total postoperative opioid consumption over the first 3 postoperative days. Patients were followed for 60 days. RESULTS: Fifty-six patients were randomized in a 1:1 fashion to the IVL or IPL groups. Total opioid consumption over the first 3 postoperative days was significantly lower in the IPL group (70.9 mg vs 157.8 mg P < 0.05) and overall opioid consumption during the total length of stay was also significantly lower (80.3 mg vs 187.36 mg P < 0.05. Pain scores were significantly lower at 2 hours postoperatively in the IPL group, however, all other time points were not significant. There were no differences in complications between the 2 groups. CONCLUSION: Perioperative use of IPL results in a significant reduction in opioid consumption following laparoscopic colon surgery when compared to IVL. This suggests that the peritoneal cavity/compartment is a strategic target for local anesthetic administration. Future enhanced recovery after surgery recommendations should consider IPL as an important component of a multimodal pain strategy following colectomy.

Outpatient parenteral antimicrobial therapy (OPAT) in the UK: findings from the BSAC National Outcomes Registry (2015-19).

BACKGROUND: Reporting of outpatient parenteral antimicrobial therapy (OPAT) outcomes with national benchmarking is key to informing service development and supporting quality improvement. OBJECTIVES: To analyse and report on data collected by the BSAC OPAT National Outcomes Registry from 2015 to 2019. METHODS: Quarterly data to 2020 was extracted from the BSAC National Outcomes Registry and analysed. RESULTS: 57 organizations submitted data on 27 841 patient episodes and 442 280 OPAT treatment days. A diverse range of infections and antimicrobials were reported with a mean OPAT treatment duration of 16.7 days (adults) and 7.7 days (paediatrics). In adults, the top five conditions treated were skin and soft tissue (27.6%), bronchiectasis (11.4%), urinary tract infections (7.6%), and diabetic foot infections (5.5%). Ceftriaxone followed by teicoplanin, ertapenem and piperacillin/tazobactam were the most-used antimicrobials. A median of 1.4 vascular-device-related complications were observed per 1000 OPAT treatment days (range 0.11 to 10.4) with device infections in 0.3 per 1000 OPAT days (range 0.1 to 1.7). Other adverse events (rash, blood dyscrasias, antibiotic-associated diarrhoea) were observed in a median of 1.9 per 1000 OPAT days. OPAT infection outcome (cured/improved) was 92.4% and OPAT outcome (success/partial success) was 90.7%. CONCLUSIONS: This report demonstrates the safety, breadth, and complexity of modern UK OPAT practice. Future analyses of OPAT data should focus on infection- and service-specific quality indicators. OPAT registries remain central to planning and assessing safe, effective, and efficient delivery of patient-centred care and should be an important focus for UK and global OPAT practice.

Safety and Efficacy of Intraperitoneal Paclitaxel Plus Intravenous Fluorouracil, Leucovorin, and Oxaliplatin (FOLFOX) for Gastric Cancer with Peritoneal Metastasis.

BACKGROUND: Peritoneal metastasis (PM) remains a major obstacle in the treatment of stage IV gastric cancer. This is a dose-escalation study of intraperitoneal (IP) paclitaxel combined with intravenous (IV) fluorouracil, leucovorin, and oxaliplatin (FOLFOX) to determine the recommended phase II dose in gastric cancer patients. METHODS: Patients with gastric adenocarcinoma and PM were enrolled. The recommended phase II dose of IP paclitaxel was determined using the standard "3 + 3" dose escalation with planned doses ranging from 40 to 100 mg/m2. IV FOLFOX was administered on the same day (oxaliplatin 100 mg/m2 (day 1), leucovorin 100 mg/m2 (day 1), fluorouracil 2,400 mg/m2 over 46 hours (day 1)). Both IP and IV regimens were repeated every 2 weeks. RESULTS: Among the 13 patients, there was no DLT at 40 and 60 mg/m2. Two patients had grade 3 febrile neutropenia at 80 mg/m2, and the recommended phase II dose was 60 mg/m2. Other patients underwent IP paclitaxel and FOLFOX without serious adverse events. Seven patients underwent second-look diagnostic laparoscopy, and the average change in PCI score was -7.0 ± 9.7. Conversion surgery rate was 23.1% (n = 3). The median overall survival was 16.6 months (95% confidence interval, 16.6-N/A), and progression-free survival was 9.6 months (95% confidence interval, 4.7-N/A). All adverse events were tolerable and manageable. CONCLUSIONS: The biweekly regimen of IP paclitaxel and FOLFOX is safe and the recommended dose of IP paclitaxel for a phase II trial is 60 mg/m2.

Adverse effects of cell-free and concentrated ascites reinfusion therapy for malignant ascites: a single-institute experience.

BACKGROUND: Cell-free and concentrated ascites reinfusion therapy (CART) is a strategy for improving various intractable symptoms due to refractory ascites, including hypoalbuminemia. CART has recently been applied in the treatment of cancer patients. This study was performed to assess the safety of CART in a single cancer institute. METHODS: We retrospectively reviewed 233 CART procedures that were performed for 132 cancer patients in our institute. RESULTS: The median weight of ascites before and after concentration was 4,720 g and 490 g (median concentration rate, 10.0-fold), The median amounts of total protein and albumin were 64.0 g and 32.6 g (median recovery rates, 44.9% and 49.0%), respectively. Thirty-three adverse events (AEs) were observed in 22 (9.4%) of 233 procedures; 30 of these events occurred after reinfusion. The most common reinfusion-related AEs were fever (13 events) and chills (10 events). Univariate analyses revealed no significant relationships between the frequency of AEs and age, sex, appearance of ascites, weight of harvested and concentrated ascites, the ascites processing rate (filtration and concentration), weight of saline used for membrane cleaning, amount of calculated total protein for infusion, or prophylaxis against AEs; the reinfusion rate of ≥ 125 mL/h or ≥ 10.9 g/h of total protein affected the frequency of AEs, regardless of the prophylactic use of steroids. CONCLUSIONS: The observed AEs were mainly mild reactions after reinfusion, which were related to a reinfusion rate of volume ≥ 125 mL/h, a simple indicator in practice, or total protein ≥ 10.9 g/h. Although our study was retrospective in nature and undertaken in a single institute, this information may be helpful for the management of cancer patients with refractory malignant ascites using CART.
