Prochlorperazine is a commonly used medicine to treat nausea and vomiting. The only liquid formulation in the UK was discontinued in November 2022 due to safety concerns. One alternative option available is to use crushed tablets instead. Crushing and mixing tablets in water to produce a liquid is a widespread practice in paediatrics. However, there is often little evidence to support this practice.In this case report, a patient established on liquid prochlorperazine mesilate who was switched to crushed prochlorperazine maleate tablets experienced significant harm. The child's vomiting became uncontrolled and led to multiple healthcare attendances and a prolonged hospital admission. Control was re-established by increasing the prochlorperazine dose to accommodate for loss of drug during preparation. Care should be taken when converting prochlorperazine mesilate liquid doses to crushed prochlorperazine maleate tablets, and the doses used should not be treated as equivalent.

Background: The use of complementary and alternative medications (CAM) is popular among cancer patients. CAM includes vitamins, minerals, phytotherapy, homeopathy, nutritional supplements and probiotics. CAM use may lead to unwanted risks by interacting with anticancer drugs; therefore, it is important for healthcare providers to be aware of CAM use by their patients. This article describes the prevalence and potential risk of CAM use in an adult Dutch cancer population. This is the first study in which CAM use was investigated using medication reconciliation.

Methods: A descriptive, observational study was conducted at Amsterdam UMC between August 2021 and July 2022. Data regarding the use of CAM was obtained by medication reconciliation reviews with inpatients and outpatients with cancer who received systemic anticancer treatment. Acquired data were evaluated by the research team, and the risks of interactions were classified into relevant, potential, unknown or no interaction. Ultimately, patient-specific recommendations on the use of CAM were provided.

Results: Of the 100 included patients, 73% used CAM during the past year and 41% used CAM actively while receiving anticancer treatment. The most common CAM were vitamins and multivitamins (both 28%). Some 10% of CAM were classified as having a relevant interaction with one or more concurrently used anticancer drugs. No association between age or gender and CAM use was found, while outpatients used significantly more CAM than inpatients (72.7% vs 32.1%; p=0.001). Patients received personalised advice from the hospital pharmacy about their CAM use.

Conclusions: More than 40% of oncology patients investigated in this study used CAM while receiving anticancer treatment, leading to unwanted risks. This prevalence is higher than reported in other studies, possibly due to the use of medication reconciliation interviews. To guarantee safety and efficacy of anticancer treatment, communication between healthcare professionals and patients about CAM is essential.

Objective: We report our experience with the use of ceftaroline in combination with daptomycin or vancomycin for methicillin resistant coagulase negative Staphylococcus bacteraemia.

Methods: A multicentre retrospective study was carried out at three institutions of adult patients with methicillin resistant S. epidermidis or S. lugdunensis bacteraemia who were managed with either daptomycin or vancomycin in combination with ceftaroline.

Results: Twelve patients met the inclusion criteria. All patients who received combination therapy had sterile blood cultures on the subsequent blood cultures drawn following ceftaroline initiation. Those who received ceftaroline combination within 7 days had a faster time to blood culture sterilisation than those who received ceftaroline combination therapy after 7 days (6 (3-7) days vs 17 (12-19) days, p=0.031).

Conclusions: The results from this case series support the use of ceftaroline combination therapy in patients with methicillin resistant coagulase negative Staphylococcus bacteraemia whose blood cultures failed to sterilise with vancomycin or daptomycin alone.

Objective: Elastomeric devices or pumps are a valuable tool to deliver outpatient parenteral therapy and have been used for administration of chemotherapy, antibiotics and pain medication. A key determinant of effective treatment is to consider the stability of medicines within these devices. It is widely known that an increase in temperature positively correlates to an increase in drug degradation. The objective of our work was to measure the temperature within soft shell elastomeric devices, under simulated outpatient treatment conditions in summer and winter months, and to determine the maximum temperature reached within these periods of use.

Methods: Thermocouples were inserted within soft shell Easypump II (B Braun Medical, Sheffield, UK) elastomeric pumps and the temperature was monitored under simulated outpatient conditions during cold and warm weather with different fill volumes. Temperature monitoring was also conducted with varying levels of insulation around the devices.

Results: Our results show that internal temperatures remained below 32°C±1°C in winter and summer months, including during times defined as a heatwave. Fill volume and ambient temperature were shown to be significant factors affecting the internal temperatures reached.

Conclusion: A soft shell Easypump II elastomeric pump, if used within its carry pouch, will maintain the internal solution below a temperature of 32°C±1°C if patients correctly adhere to handling guidance. Our results show that further improvements to the insulation material used in carry pouches can significantly restrict the rate of temperature rise within the pumps and will give more assurance in relation to preventing degradation especially considering the increases in extreme weather conditions observed in recent years due to global warming.

Introduction: Intravenous vedolizumab is a widely used monoclonal antibody for outpatients with inflammatory bowel disease. Drug preparation is performed on the day of administration, but is time consuming, causing unnecessary in-hospital patient delay and inefficient logistics for preparation and distribution. Storage of vedolizumab ready-to-administer infusions and distribution via pneumatic air tubes could streamline logistics in the outpatient setting. The aim of this study was to test the shelf life and stability of ready-to-administer intravenous infusion bags containing vedolizumab.

Methods: For assessing in-use shelf life, the reconstituted product (300 mg fixed dose) was diluted to a concentration of 1.2 mg/mL in 0.9% NaCl under aseptic conditions, and stored in polyolefin infusion bags at 2-8°C prior to analysis. On replicate samples, we measured concentration, physical and chemical stability using sodium dodecyl sulphate polyacrylamide gel electrophoresis, size exclusion chromatography, and multi-angle laser light scattering, as well as biological activity using a biolayer interferometry assay to study target engagement, and endotoxin content to assess microbiological stability. Stability of ready-to-use vedolizumab was assessed also after transportation via pneumatic tube system. Samples were taken at different time points over an observation period of 30 days on four replicate samples.

Results: For all parameters assessed, the ready-to-use solution of vedolizumab remained stable over a period of at least 30 days. There were no signs of protein aggregation, chemical instability, or loss of binding of the antibody to the α4β7 integrin target. There was no increase in endotoxin concentration over time. No significant difference was seen in antibody structural stability and protein aggregation between samples before and after transportation via pneumatic tube system.

Conclusion: When prepared under aseptic conditions, dissolved ready-to-administer vedolizumab infusion bags can be stored long term at 2-8°C and transported via pneumatic air tube, without observable loss of antibody stability or binding activity.

This case report investigates elevated serum concentrations of inhaled tobramycin in a patient with chronic kidney disease. The patient, a man in his early 80s with complex comorbidities, underwent tobramycin inhalation therapy for chronic respiratory infections caused by Pseudomonas aeruginosa Despite the strategic localised treatment approach, unexpectedly high plasma tobramycin concentrations were observed. After a dosage adjustment guided by a pharmacokinetic-pharmacodynamic model, a final inhalation dose of 300 mg of tobramycin was determined at a 24-hour interval. This case report underscores the need for rigorous monitoring of plasma tobramycin levels in patients with renal impairment undergoing inhaled tobramycin therapy, advocating for enhanced pharmacokinetic models to improve the safety and efficacy of the treatment.

Purpose: This study investigates the clinical impact of electronic patient-reported outcome (ePRO) monitoring apps/web interfaces, aimed at symptom-management, in cancer patients undergoing outpatient systemic antineoplastic treatment. Additionally, it explores the advantages offered by these applications, including their functionalities and healthcare team-initiated follow-up programmes.

Methods: A systematic literature review was conducted using a predefined search strategy in MEDLINE. Inclusion criteria encompassed primary studies assessing symptom burden through at-home ePRO surveys in adult cancer patients receiving outpatient systemic antineoplastic treatment, whenever health outcomes were evaluated. Exclusion criteria excluded telemedicine-based interventions other than ePRO questionnaires and non-primary articles or study protocols. To evaluate the potential bias in the included studies, an exhaustive quality assessment was conducted, as an additional inclusion filter.

Results: Among 246 identified articles, 227 were excluded for non-compliance with inclusion/exclusion criteria. Of the remaining 19 articles, only eight met the rigorous validity assessment and were included for detailed examination and data extraction, presented in attached tables.

Conclusion: This review provides compelling evidence of ePRO monitoring's positive clinical impact across diverse cancer settings, encompassing various cancer types, including early and metastatic stages. These systems are crucial in enabling timely interventions and reducing communication barriers, among other functionalities. While areas for future ePRO innovation are identified, the primary limitation lies in comparing clinical outcomes of reviewed articles, due to scale variability and study population heterogeneity. To conclude, our results reaffirm the transformative potential of ePRO apps in oncology and their pivotal role in shaping the future of cancer care.

Objectives: To establish a clinical application monitoring system for proton pump inhibitors (PPI-MS) and to enhance the detection and intervention of inappropriate PPI use in adult hospitalised patients.

Methods: Natural language processing technology was applied to indication recognition of therapeutic PPI applications and the assessment of admission record recognition for preventive PPI applications. Symptom judgement was based on the tense-negation model and regular expressions. Evidence-based rules for clinical PPI application were embedded for the construction of PPI-MS. A total of 9421 patient records using PPI from July 2022 to July 2023 were analysed to validate the performance of the system and to identify common issues related to inappropriate clinical PPI use.

Results: Out of 9421 hospitalised patients detected using PPI, 4736 (50.27%) were used for prophylaxis and the rest for therapeutic use. Among the prophylactic medications, 2274 patients (48.02%) were identified as receiving inappropriate prophylactic PPI. The main reasons were inappropriate prophylaxis without indication. Additionally, 258 cases of inappropriate therapeutic PPI use were identified, mainly involving the use of esomeprazole for peptic ulcers and Zollinger-Ellison syndrome. The efficiency of the PPI rational medication monitoring system, when coupled with human involvement, was 32 times that of manual monitoring. Among cases of inappropriate prophylactic PPI use, 45.29% were due to lack of indications, 28.34% involved inappropriate administration routes, 15.74% were related to inappropriate dosing frequencies and 10.62% were attributed to inappropriate drug selection. There were 933 cases related to the use of antiplatelet and anticoagulant drugs and 708 cases related to the use of non-steroidal anti-inflammatory drugs. The overall accuracy of the PPI-MS system was 88.69%, with a recall rate of 99.33%, and the F1 score was 93.71%.

Conclusions: Establishing a PPI medication monitoring system through natural language processing technology, while ensuring accuracy and recall rates, improves evaluation efficiency and homogeneity. This provides a new solution for timely detection of issues relating to clinical PPI usage.

The UK has fallen from fourth to 10th place in the global ranking for clinical trial activities in the past 6 years. Due to the limited capacity of the clinical trial pharmacy workforce and delays in providing pharmacy approvals, pharmacy has been identified as one of the constraining services that delays the set-up and delivery of clinical trials. To tackle this problem, we developed a single pharmacy review process for multicentre trials across Greater Manchester (GM) and tested its feasibility and implementation in our region. A survey completed by each GM Trust suggests that this harmonised pharmacy review process for multicentre studies would expedite trial set-up time at each pharmacy site and standardise the pharmacy review process in GM. We therefore believe that this harmonised review process could potentially reduce pharmacy set-up time and reposition the UK in the global market for clinical trials.

Objectives: In the Danish healthcare system, restructuring is an ongoing process to accommodate the rising number of patients and to optimise resource allocation. To ease departmental burdens at hospitals in the North Denmark Region, outpatients are empowered to collect their cost-free medicines from medication pick-up lockers. The lockers function similarly to a package box, thereby enhancing patient freedom. Due to lack of evidence within the published literature regarding cost-free medicines and medicine waste, the aim of our study was to identify the common medications delivered to medicine pick-up lockers and secondly, to evaluate potential medicine waste.

Methods: Data from ApoVision provided insights into medications delivered to medicine pick-up lockers from March to October 2023 in the North Denmark Region. To estimate unused medicines we obtained data on the number of medications returned from medicine pick-up lockers.

Results: From 2020 to 2023, the number of patients receiving cost-free medicines at medication pick-up lockers increased. In total, approximately 30 000 packages of medicine were delivered to medicine pick-up lockers from March to October 2023 in the North Denmark Region; 1.7% were returned. Methotrexate, adalimumab, and omalizumab were among the most common deliveries and were also the three most returned from the medicine pick-up lockers.

Conclusions: This study is an initial attempt to investigate potential medicine waste in cost-free medicines dispensed to outpatients via pick-up lockers. Antineoplastic and immunomodulating agents were the most common medicines delivered to medication pick-up lockers in the North Denmark Region from March to October 2023. In this period, approximately 2% of all delivered medicine packages were returned to the hospital pharmacy. Our analysis solely focuses on waste associated with medications left uncollected from medicine pick-up lockers. Addressing the impact of medicine waste in a hospital setting requires a comprehensive approach, thus future studies should also focus on other sites relevant for medication waste as, for example, the patient's household.
