Perceived quality of life by patients with immune-mediated inflammatory diseases treated with biological therapies. SACVINFA study

OBJECTIVES

To evaluate health-related quality of life perceived by patients with the most prevalent immune-mediated inflammatory diseases in Spain: inflammatory bowel disease (IBD), psoriasis (Ps), psoriatic arthritis (AP), rheumatoid arthritis (RA), and spondyloarthropathies (SpAs), and to determine the factors that influence patient quality of life.

METHODS

The SACVINFA study (SA=satisfaction, CV=quality of life, IN=immune-mediated, FA=pharmacy) consisted of an observational study conducted in 4 hospitals in the Community of Madrid. A cross-sectional analysis was made for adult patients diagnosed with an immune-mediated inflammatory disease who attended the Pharmacy Service. Quality of life was assessed using the EQ-5D-5L questionnaire (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression) and specific questionnaires: SIBDQ-9, DLQI, PsAQoL, QoL-RA, and ASQoL.

RESULTS

A total of 578 patients were analysed (inflammatory bowel disease=25.3%; psoriasis=19.7%; spondyloarthropathies=18.7%; rheumatoid arthritis=18.5%; psoriatic arthritis=17.8%). The mean age (standard deviation) was 49.8 (12.3) years and 50.7% were male. The average score (standard deviation) for the global EQ-5D-5L was 0.771 (0.2) and the mean (standard deviation) visual analogue scale score was 71.5 (20.0). Type of immune-mediated inflammatory diseases was associated with differences in quality of life showing psoriasis and inflammatory bowel disease higher values of EQ5D-5L than psoriatic arthritis, rheumatoid arthritis, and spondyloarthropathies, p<.05 in all comparisons. Patients with RA, IBD, and Ps achieved 70% of the maximum score, while patients with PsA and SpAs did not reach 50% of the maximum possible score. Female gender, a state of moderate/severe disease severity, an older age, and a higher number of previous treatments were correlated with worse quality of life. Conversely, persistence to current treatment correlated with better quality of life.

CONCLUSIONS

Patients with immune-mediated inflammatory diseases have markedly affected quality of life, mainly in the pain/discomfort dimension, especially in those immune-mediated inflammatory diseases with a rheumatological component.

Medication guide for dose adjustment and management of cardiotoxicity and lipid metabolic adverse events of oral antineoplastic therapy

Objective

The management of cardiotoxicity concerning the use of oral antineoplastic agents (OAAs) is a challenge for healthcare professionals. Our objective was to create a comprehensive medication management guide with dose adjustment recommendations on OAAs concerning cardiotoxic and lipid metabolic adverse events (AEs) to assist healthcare professionals when prescribing OAAs.

Materials and methods

A review of the available information on all dose adjustments necessary to safely prescribe and dispense OAAs concerning cardiotoxicity was conducted. In January 2023, we identified all OAAs authorized by the European Medicines Agency (EMA). For each drug, the latest summary of product characteristics (SPC) approved by the EMA and the tertiary data source Lexicomp® were reviewed. Cardiotoxic AEs were recorded, namely, QT interval prolongation, decrease in left ventricular ejection fraction (LVEF), imbalances in blood pressure (hypertension and hypotension), alterations in heart rate (tachycardia and bradycardia), and thrombosis. Any available dose adjustment recommendations in case of an occurrence of these adverse events were collected.

Results

In all, 93 different OAAs had been approved by the EMA and were reviewed. Among them, 51.6% have recognized cardiotoxic AEs and 10.8% can cause alterations in lipid metabolism. A total of 27 (29.0%) OAAs had specific recommendations regarding QT prolongation; 88.9% were listed in the SPC and 59.3% in Lexicomp®. Eight OAAs (9.68%) have reported a decrease in LVEF, and four of these drugs, namely, encorafenib, lorlatinib, ripretinib, and sunitinib, have specific management recommendations. Almost half (49.5%) of currently approved OAAs can potentially alter blood pressure; 34 (36.6%) of them have been reported to cause hypertension and 12 (12.9%) are related to hypotension. Tachycardia and/or bradycardia are associated with 22.6% and 8.6% of the evaluated drugs, respectively. Regarding thrombosis, 30 (32.3%) of the drugs analyzed included the appearance of a thrombus as a possible AE.

Conclusions

More than half of the OAAs can produce cardiotoxic effects, with the most frequent being blood pressure alteration and QT interval prolongation with a non-depreciable incidence of LV dysfunction or thrombosis. Before starting the treatment, it is necessary to stratify baseline cardiovascular risk, plan a surveillance schedule, and consider referral to cardio-oncology units.

Anti-interleukin-17 therapies for moderate/severe psoriasis in clinical practice: effectiveness, safety and association with clinical patient factors

OBJECTIVES

Interleukin-17 (IL-17) contributes to the pathogenesis of psoriasis. Secukinumab, ixekizumab, and brodalumab are monoclonal antibodies anti-IL-17 antibodies, approved for the treatment of moderate/severe plaque psoriasis.The aim of the study was to describe the effectiveness and safety of anti-IL-17 agents in moderate/severe plaque psoriasis in clinical practice. We also analysed anti-IL-17 therapies' survival, dose adjustment, and clinical patients' factors associated with their effectiveness and safety.

METHODS

A retrospective, longitudinal study was conducted at a tertiary hospital. We included patients with moderate/severe psoriasis treated with anti-IL-17 agents. The effectiveness was evaluated with Psoriasis Area and Severity Index (PASI) score and safety through the adverse drug reactions (ADRs) collected.

RESULTS

38 patients were studied (median age=47.4 years, 71.0% male). The mean number of biological therapies that patients received was 2.6, and anti-IL-17 therapy was the first biological therapy for 36.8% of patients. The median years in treatment were 2.5 (95% CI 1.95 to 2.98) for secukinumab, 1.2 (95% CI 0.36 to 1.47) for ixekizumab, and 0.7 (IQR 0.71) for brodalumab. The median PASI score after 6 months of treatment was 0 (IQR 0) and 85.3% of patients achieved a PASI of 90 (84.0% with secukinumab, 87.5% with ixekizumab, and 100% with brodalumab). Dose adjustment was associated with the line of treatment (p=0.034 for naïve patients), age (p=0.044 for younger patients), and concomitant pathologies (p=0.015 without more diseases).24 patients suffered from ADRs, mainly infections of the upper respiratory tract, and there were no statistically significant differences between the three therapies.

CONCLUSIONS

Anti-IL-17 agents constitute an effective treatment for patients with moderate/severe plaque psoriasis and for longer. Dose reductions were associated with fewer lines of treatment, younger patients and absence of concomitant pathologies. ADR were minor and similar among the anti-IL-17.

Economic burden of locoregional and metastatic relapses in resectable early-stage non-small cell lung cancer in Spain

BACKGROUND

There are scarce data of the costs of non-small cell lung cancer (NSCLC) recurrence in Spain. The objective of this study is to assess the economic burden of disease recurrence, for both locoregional and/or metastatic relapses, after appropriate early-stage NSCLC treatment in Spain.

MATERIALS AND METHODS

A two-round consensus panel of Spanish oncologists and hospital pharmacists was conducted to collect information on patient's flow, treatments, use of healthcare resources and sick leaves in patients with relapsed NSCLC. A decision-tree model was developed to calculate the economic burden of disease recurrence after appropriate early-stage NSCLC. Both direct and indirect costs were considered. Direct costs included drug acquisition and healthcare resources costs. Indirect costs were estimated using the human-capital approach. Unit costs were obtained from national databases (euros of 2022). A multi-way sensitivity analysis was performed to provide a range to the mean values.

RESULTS

Among a cohort of 100 patients with relapsed NSCLC, 45 patients would have locoregional relapse (36.3 would eventually progress to metastasis and 8.7 would be considered in remission) and 55 patients would have metastatic relapse. Over time, 91.3 patients would experience a metastatic relapse (55 as first relapse and 36.6 after previous locoregional relapse). The overall cost incurred by the 100-patients cohort is €10,095,846 (€9,336,782 direct costs, €795,064 indirect costs). The average cost of a locoregional relapse is €25,194 (€19,658 direct costs, €5536 indirect costs), while the average cost a patient with metastasis who receives up to 4 lines of treatment is €127,167 (€117,328 direct, €9839 indirect).

CONCLUSIONS

To our knowledge, this is the first study that specifically quantifies the cost of relapse in NSCLC in Spain. Our findings shown that the overall cost of a relapse after appropriate treatment of early-stage NSCLC patients is substantial, and it increases considerably in the metastatic relapse setting, mainly due to the high cost and long duration of first-line treatments.

Cost-effectiveness of adjuvant atezolizumab versus best supportive care in the treatment of patients with resectable early-stage non-small cell lung cancer and overexpression of PD-L1

AIMS

To assess the cost-effectiveness of adjuvant atezolizumab in the treatment of early-stage NSCLC patients (stage II-IIIA) with expression PD-L1 ≥ 50% without mutations in EGFR or ALK rearrangements in Spain.

MATERIALS AND METHODS

A 5-states Markov model (DFS, locoregional recurrence, 1 L-metastatic recurrence, 2 L-metastatic recurrence, and death states) was adapted to the Spanish setting. Demographic characteristics of the hypothetical cohort, transition probabilities from the DFS state, and safety parameters were obtained from IMpower010 study (GO29527). Transition probabilities from locoregional and metastatic health states were obtained from the literature. The usual clinical practice in Spain (use of health resources, management of the disease, etc.) was obtained from a previous analysis carried out by the authors of this study. A societal perspective was considered so both direct and indirect costs were included (expressed in € of 2021). A lifetime horizon was used, so costs and health outcomes were discounted at 3% per year. Sensitivity analyses were performed to evaluate uncertainty.

RESULTS

Over a lifetime horizon, treatment with adjuvant atezolizumab provided greater effectiveness (+2.61 life years [LY] and +1.95 quality-adjusted life years [QALY]) and higher cost (€+22,538) than BSC. The incremental cost-effectiveness ratio (ICER) and incremental cost-utility ratios (ICUR) of the analysis were €8,625/LY gained and €11,583/QALY gained, respectively. Robustness of these base-case results was confirmed by the sensitivity analyses performed. In the probabilistic sensitivity analysis, 90% of the simulations performed showed that adjuvant atezolizumab is cost-effective versus BSC, considering a threshold of €30,000/QALY.

CONCLUSIONS

Our results showed that adjuvant treatment with atezolizumab in patients with early-stage resected NSCLC with overexpression of PD-L1 and without EGFR and ALK mutations is cost-effective versus BSC as the ICERs and ICURs obtained are below the cost-effectiveness thresholds commonly considered in Spain, thus offering a new treatment alternative for these patients.

Possible heart failure caused by osimertinib in a lung cancer patient

Introduction

Osimertinib is a third-generation tyrosine kinase inhibitor (TKI) indicated for the treatment of epidermal growth factor receptor mutated non-small cell lung cancer (NSCLC). It has demonstrated better results concerning effectiveness than other TKIs for the same indication. However, despite a good safety profile, it could produce some cardiotoxicity that does not occur with other drugs of the same group.

Case report

We report the evolution and management of a female patient diagnosed with NSCLC who developed a grade 3 cardiotoxicity due to treatment with osimertinib. This patient suffered from a left bundle branch block, dyslipidemia, and hypertension as cardiovascular risk factors. After a long period of treatment with osimertinib, she developed a severe heart failure (HF) with an important decrease in left ventricular ejection fraction (LVEF), which triggered an admission to the oncology unit for eight days.

Management and outcomes

Treatment with osimertinib was first suspended and then resumed after stabilization of the HF. She also developed atrial fibrillation during admission and has required narrow cardiac monitoring and management since the debut of the HF. After evaluating the benefit-risk balance, osimertinib was reintroduced and the patient continues in treatment at the moment, although the baseline LVEF is not recovered.

Discussion

There is scarce evidence in the literature concerning HF and important LVEF decrease due to osimertinib. However, its severity and repercussion for the patient justify the thorough screening of cardiovascular risk factors before starting the therapy.

Evaluation of the hospital care quality perceived by patients with immune-mediated inflammatory diseases from the pharmacy service. SACVINFA study

WHAT IS KNOWN AND OBJECTIVE

Immune-mediated inflammatory diseases (IMIDs) are a group of chronic and highly disabling diseases. The objective is to evaluate the satisfaction with the health care received by patients with the most prevalent IMIDs in Spain: inflammatory bowel disease (IBD), psoriasis (Ps) psoriatic arthritis (PsA), rheumatoid arthritis (RA) and spondyloarthropathies (SpAs), and to determine the factors that influence patient satisfaction.

METHODS

This was an observational, cross-sectional, multicentre study in a real-world evidence context conducted in the Pharmacy Service in four hospital centres of the Community of Madrid that belong to the National Health System. The study included adult patients diagnosed with an IMID who had attended the Pharmacy Service at least three times. The patients were grouped according to the main IMID. Health care satisfaction was evaluated using the chronic patient experience assessment (IEXPAC) questionnaire. The responses to IEXPAC are grouped into three factors: productive interactions, new relational model and patient self-management, with a total score from 0 (worst) to 10 (best experience). Health-related quality of life (HRQoL) was also evaluated using the EQ-5D-5L questionnaire, and pharmacological adherence was evaluated through the Morisky-Green test.

RESULTS AND DISCUSSION

A total of 578 patients were analysed (IBD = 25.3%; Ps = 19.7%; SpAs = 18.7%; RA = 18.5%; PsA = 17.8%). The mean age (SD) was 49.8 (12.3) years and 50.7% were male. The average score (SD) for the total IEXPAC sample was 6.6 (1.9). RA was the IMID with the lowest score, at 5.83 (2.0), significantly lower than the scores of Ps (SD) [7.01 (1.7); p = 0.003], IBD [6.83 (1, 9); p = 0.012] and SpAs [6.80 (1.6); p = 0.001]. Productive interactions (SD) [8.5 (1.8)] and patient self-management (SD) [7.3 (2.3)] were the factors with the highest scores, and the new relational model had the lowest score (SD) [3.2 (2.7)]. Male gender, a longer time interval between medication administrations and a higher HRQoL were correlated with better patient satisfaction. Current biological therapy (according to the Anatomical Chemical classification system) also had a significant influence; patients treated with tumour necrosis factor inhibitors and interleukin inhibitors showed greater satisfaction than those treated with selective immunosuppressants.

WHAT IS NEW AND CONCLUSION

The IEXPAC results show high general satisfaction with care quality reported by patients with IMIDs treated in the Pharmacy Service. However, there are areas of improvement in care quality specially health professional-patient communication, such as increasing access to information, and promoting and facilitating relationships with patients in similar conditions.

A smartphone app to improve the safety of patients undergoing treatment with oral antineoplastic agents: 4 years of experience in a university hospital

Objective

This study aims to analyze the impact of the eOncosalud app on the management and follow-up of adverse effects (AE) in patients receiving oral antineoplastic agents.

Material and methods

We performed an observational, prospective study of cancer outpatients treated with oral antineoplastic agents (OAA), monitored by the eOncosalud app between August 2017 and October 2021. Safety variables were collected from eOncosalud: the number of AE; severity of the AE according to CTCAE, version 4.03; timelapse from app installation to first recorded AE; automatic recommendations issued; and the patient's acceptance of the recommendations made. To assess the impact of the recommendations generated by the algorithm, we calculated the positive predictive value (PPV) as the number of recommendations accepted out of the total number of recommendations generated. Safety-related patient messages were also analyzed (AE, drug-drug interactions, drug administration).

Result

The app was downloaded and used by 186 patients (58.0% women), with a mean age of 59.0 years. A total of 1,368 AE were recorded, the most frequent being fatigue (19.37%), diarrhea (18.20%), and skin changes (9.21%). Regarding the recommendations issued by the app algorithm, 102 patients received 344 information brochures, 39 patients received 51 recommendations for supportive care to control AE, 60 patients received 240 recommendations to visit their primary care doctor, 14 patients received 16 recommendations to contact their specialist pharmacist or oncologist-hematologist, and 34 patients received 73 recommendations to go to the emergency room. The suggestion to go to the emergency room and contact the specialist pharmacist or oncologist-hematologist had a PPV of 0.51 and 0.35, respectively. Half of the patients (50.4%) used the messaging module. A total of 1,668 messages were sent. Of these, 47.8% were related to treatment safety: AE, 22.7%; drug-drug interactions, 20.6%; drug administration, 3.6%; and missing a dose, 1.0%.

Conclusions

The eOncosalud app enables close, real-time monitoring of patients treated with OAA. The automatic recommendations through the app's algorithm have optimized available healthcare resources. The app facilitated early detection of AE, thus enabling patients themselves to improve the safety of their treatment.

Implementation and evaluation of a home pharmaceutical care model through Telepharmacy

OBJECTIVE

To describe the impact of a Specialized Pharmaceutical Care model  that includes pharmacotherapeutic monitoring of patients through an  Telepharmacy platform and home medication dispensing.

METHOD

A descriptive and retrospective study conducted in the Pharmacy Service of a tertiary hospital, between 23 March 2020 and 31  December 2021. A new pharmaceutical care model for chronic ambulatory  patients was developed, including: (i) definition of criteria for selecting  Telepharmacy candidate patients; (ii) stratification of patients by risk level; (iii)  definition of individualized pharmacotherapeutic monitoring; (iv)  adaptation of the Pharmacy Service app platform to ensure continuous pharmacotherapeutic monitoring and patient monitoring (e- Oncohealth, e-Midcare and farMcuida), (v) implementation of an appointment  system; and (vi) development of a software module for the management of  home medication delivery. The impact of this pharmaceutical care model was assessed by analyzing indicators of activity, safety, adherence and  perceived quality. Moreover, an additional study on the impact of COVID‑19 was developed in order to assess the accessibility of medical care  and continuity of treatment through a survey conducted on a random sample of 100 patients.

RESULTS

During the study period, 2,737 patients benefited from the new  remote pharmaceutical care model. A total of 7,758 Telepharmacy consultations were performed. Pharmacotherapeutic monitoring  prevented 1,043 adverse drug reactions, which affected 10.4% of patients  (3.6 adverse drug reactions/patient). Mean adherence to treatment  was 95.2%. Overall satisfaction with the new model was 9.8/10. All patients would recommend this model to other patients.

CONCLUSIONS

The new Pharmaceutical care model increases patient safety and  improves treatment adherence, with a high perceived quality. Patient  stratification and individualized follow-up via an Telepharmacy platform were  crucial to the development of this model.

Design and implementation of a mobile app for the pharmacotherapeutic follow-up of patients diagnosed with immune-mediated inflammatory diseases: eMidCare

Background

Pharmacotherapeutic management of immune-mediated inflammatory diseases (IMID) has become more complex due to the development of new treatments, such as biological therapies. Mobile health, especially apps, can provide IMID patients with greater autonomy and facilitate communication with healthcare professionals. Our objective was to design and implement an app for remote monitoring and communication with IMID patients.

Methods

A multidisciplinary group was created to design and develop an app for IMID patients in a tertiary hospital. The app functionalities were identified through a focus group with IMID patients and through an observational, descriptive study of available apps for IMID patients at App Store and Play Store platforms. Once the app was designed and developed, we offered the app to IMID patients who initiated a new biological therapy. The inclusion period was from December 2020 to August 2021. We performed an observational, longitudinal study to assess the app’s impact on medication safety, communication, satisfaction, and usability.

Results

We designed an app (eMidCare®) with the following modules: My Medication, My Questionnaires, Adverse Events, Useful Information, Messages, and Patient Profile. A total of 85 patients were installed with the app. The median (range) follow-up time for app use was 123 (5-270) days. In the My Medication module, 100% of patients registered their biological therapy and 25.9% also used this module to record each dose of medication administered. A total of 82 adverse events (AEs) were registered. Thirty-two percent of the patients registered at least 1 AE. The most frequent AEs were fatigue, injection site reaction, headache, and nausea. Fifty-two percent of patients used the Messages module to communicate with healthcare professionals. The most frequent messages concerned doubts about managing AEs (26.2%) and drug interactions (18.9%). The satisfaction survey yielded a median (range) score of 9.1 (7-10) out of 10.

Conclusions

We developed an app, eMidCare®, which reminds patients to take their medication, enables them to record AEs, and helps them communicate with healthcare professionals. Approximately one-third of the patients registered the administration of the biological therapies and registered at least 1 AE. The most used and most satisfactory functionality was communication with health professionals.

Smartphone-Based Ecological Momentary Assessment for the Measurement of the Performance Status and Health-Related Quality of Life in Cancer Patients Under Systemic Anticancer Therapies: Development and Acceptability of a Mobile App

Background

We have defined a project to develop a mobile app that continually records smartphone parameters which may help define the Eastern Cooperative Oncology Group performance status (ECOG-PS) and the health-related quality of life (HRQoL), without interaction with patients or professionals. This project is divided into 3 phases. Here we describe phase 1. The objective of this phase was to develop the app and assess its usability concerning patient characteristics, acceptability, and satisfaction.

Methods

The app eB2-ECOG was developed and installed in the smartphone of cancer patients who will be followed for six months. Criteria inclusion were: age over 18-year-old; diagnosed with unresectable or metastatic lung cancer, gastrointestinal stromal tumor, sarcoma, or head and neck cancer; under systemic anticancer therapies; and possession of a Smartphone. The app will collect passive and active data from the patients while healthcare professionals will evaluate the ECOG-PS and HRQoL through conventional tools. Acceptability was assessed during the follow-up. Patients answered a satisfaction survey in the app between 3-6 months from their inclusion.

Results

The app developed provides a system for continuously collecting, merging, and processing data related to patient’s health and physical activity. It provides a transparent capture service based on all the available data of a patient. Currently, 106 patients have been recruited. A total of 36 patients were excluded, most of them (21/36) due to technological reasons. We assessed 69 patients (53 lung cancer, 8 gastrointestinal stromal tumors, 5 sarcomas, and 3 head and neck cancer). Concerning app satisfaction, 70.4% (20/27) of patients found the app intuitive and easy to use, and 51.9% (17/27) of them said that the app helped them to improve and handle their problems better. Overall, 17 out of 27 patients [62.9%] were satisfied with the app, and 14 of them [51.8%] would recommend the app to other patients.

Conclusions

We observed that the app’s acceptability and satisfaction were good, which is essential for the continuity of the project. In the subsequent phases, we will develop predictive models based on the collected information during this phase. We will validate the method and analyze the sensitivity of the automated results.

Complementary and alternative medicine in cancer patients: characteristics of use and interactions with antineoplastic agents

PURPOSE

Our objectives were to analyze the use of complementary and alternative medicine (CAM) in cancer patients and to describe the incidence and characteristics of interactions between CAM and antineoplastic agents.

METHODS

We performed an observational study in cancer outpatients at a university hospital. Variables were collected through a 22-item questionnaire. Potential interactions between CAM and antineoplastic agents were analyzed using the Lexicomp^®, the About Herbs^®, and the summary of product characteristics. Mechanism of action, reliability, and the potential clinical effect of interactions were analyzed.

RESULTS

The study population comprised 937 patients, of whom 65% used CAM (70.6% herbal products, 25.8% dietary supplements, and 3.6% homeopathy). Female sex, younger age, and breast cancer were associated with more frequent use of CAM. The primary source of information about CAM was friends and family (43.5%). A total of 335 (57.1%) patients did not tell their doctor that they took CAM. The five most common CAM were chamomile, green tea, pennyroyal mint, linden, and rooibos. At least one interaction between CAM and antineoplastic agents was reported by 65.0% of CAM users (33.9% of all patients). Depending on the mechanism of action, 80% of CAM diminished the metabolism of the antineoplastic agents.

CONCLUSION

Our results reveal a high incidence of interactions between CAM and antineoplastic agents. The most frequent CAM were herbal products. Family and friends were the primary sources of information that led patients to start taking CAM, and more than half of the patients did not tell their doctor that they were taking CAM.

A New Methodology to Estimate Drug Cost Avoidance in Clinical Trials: Development and Application

Background

Oncology clinical trials can lead to relevant financial savings in drug acquisition for healthcare providers. Considerable methodological heterogeneity is observed among previous studies estimating these savings.

Methods

We developed a methodology to estimate the economic benefit obtained from the enrollment of patients into clinical trials through the analysis of drug cost avoidance. We designed a decision algorithm to determine if a clinical trial is associated with drug cost avoidance. This algorithm is based on five scenarios according to the availability or not of standard treatment, the presence or absence of a control arm (placebo or active treatment), and the provider of the medication. We considered as reference the cost of the standard treatment that the patient would have received in routine clinical practice. We standardized drug doses and treatment durations according to the literature. Costs were considered from a National Health System perspective. We applied this methodology at a single, research-active University Hospital in 2019. A cost avoidance analysis per trial and patient was carried out on cancer patients.

Results

We analyzed 140 trials in which 198 patients were recruited. Drug cost avoidance was found in 120 trials (85.7%). The estimated total drug cost avoidance amounted to over €3,200,000. Melanoma and genitourinary tumors were the tumor types associated with the highest cost avoidance. The average drug cost avoidance per patient was €16,245.

Conclusion

We describe a standardized method to estimate drug cost avoidance in clinical trials. We have applied it to all ongoing oncology clinical trials in our center. This methodology could be valuable for other centers to analyze the potential saving of clinical trials.

Defining a Standard Set of Patient-Reported Outcomes for Patients With Advanced Ovarian Cancer

Purpose

Advanced ovarian cancer (AOC) and its treatment cause several symptoms and impact on patients’ health-related quality of life (HRQoL). We aim to reach a consensus on the most relevant patient-reported outcome (PROs), the corresponding measures (PROMs), and measurement frequency during AOC patients’ follow-up from patients’ and healthcare professionals’ (HCP) perspective.

Methods

The project comprised five steps: 1) a literature review, 2) a focus group with patients, 3) a nominal group with HCP, 4) two round-Delphi consultations with patients and HCP, and 5) a final meeting with HCP. Delphi questionnaire was elaborated based on literature review, focus group (n=5 patients), and nominal group (n=16 HCP). The relevance of each PRO and the appropriateness (A) and feasibility (F) of the proposed PROM were assessed (Likert scale 1=strongly agree; 9=strongly disagree). The consensus was reached when at least 75% of the panelists rated it as ‘relevant’, ‘appropriate’, or ‘feasible’ (score 7-9).

Results

A total of 56 HCP [51.8% Hospital Pharmacy; 41.1% Oncology; 3.6% Nursing; and 3.6% Psycho-oncology; mean time in specialty 12.5 (8.0) years] and 10 AOC patients [mean time diagnosis 5.4 (3.0) years] participated in the 1^st round. All PROs achieved consensus regarding their relevance, except dry skin (58.0%). Agreement was reached for PRO-CTCAE to be used to assess fatigue (A:84.9%; F:75.8%), neuropathy (A:92.4%; F:77.3%), diarrhea (A:87.9%; F:88.7%), constipation (A:86.4%; F:75.8%), nausea (A:89.4%; F:75.8%), insomnia (A:81.8%; F:88.7%), abdominal bloating (A:82.2%; F:82.2%) and sexuality (A:78.8%; F:88.6%); EQ-5D to determine patients’ HRQoL (A:87.9%; F:80.3%), pain (A:87.9%; F:75.8%) and mood (A:77.7%; F:85.5%); to assess treatment adherence the Morisky-Green (A:90.9%; F:84.9%) and the dispensing register (A:80.3%; F:80.3%) were chosen. It was agreed to note in the medical record whether the patient’s treatment preferences had been considered during decision-making (A:78.8%; F:78.8%) and to use a 5-point Likert scale to assess treatment satisfaction (A:86.4%; F:86.4%). Panelists agreed (A:92.4%; F: 77.3%) to collect these PROs (1) at the time of diagnosis/relapse; (2) one month after starting treatment/change therapeutic strategy; (3) every three months during the 1^st-year of treatment; and later (4) every six months until treatment completion/change.

Conclusions

The consensus reached represents the first step towards including the patient’s perspective in AOC follow-up. The standardized collection of PROs in clinical practice may contribute to optimizing the follow-up of these patients and thus improving the quality of care.

Implementation of a methodology to assess patient reported outcomes in lung cancer patients: The PeOpLe (Patient-reported Outcomes in Lung cancer ) study protocol

OBJECTIVE

The purpose of this article is to describe the PeOpLe study protocol, developed to assess patient-reported health outcomes in  advanced or metastatic non-small-cell lung cancer in routine clinical practice using the methodology provided by the International Consortium for Health Outcomes Measurement tool.

METHOD

The study envisaged will be multicenter, longitudinal, ambispective and observational. Two groups will be compared: a control group (followed up according to standard clinical practice) and an experimental group (followed up using the International Consortium for Health  Outcomes Measurement methodology adapted to the Spanish setting for 6  months). The variables collected will be related to demography (age, sex,  degree of family support), clinical factors (smoking, comorbidities, lung  capacity), the neoplasm (histology, staging, mutations), pharmacotherapy  (treatment schedule, modifications, and complications), health status  (functional status, quality of life, satisfaction and overall survival) and resource consumption (emergency visits, hospital admissions and time spent by health providers). The PeOpLe study protocol has been approved by the Ethics Committee for Research into Medicinal Products of the Gregorio Marañón General University Hospital and will be conducted in compliance with prevailing ethical principles and standards.

CONCLUSIONS

The PeOpLe study will explore how patient-reported outcomes collection can be developed and integrated with the clinical processes used in  the management of patients with locally advanced or metastatic nonsmall cell  lung cancer what patient-reported outcomes can be measured with systems  that can conveniently be used both by patients and by healthcare providers.  Systematic evaluation of patient-reported outcomes will help determine their  impact in terms of effectiveness (survival), safety (complications of systemic  therapy), and quality of life and patient satisfaction. The multidisciplinary and  multicenter nature of the study will facilitate a comprehensive view of the  subject analyzed and allow external reproducibility.

Cost-utility analysis of venetoclax in combination with obinutuzumab as first-line treatment of chronic lymphocytic leukaemia in Spain

OBJECTIVE

Venetoclax in combination with obinutuzumab has significantly improved efficacy versus immunochemotherapy (progression-free survival) in patients with chronic lymphocytic leukaemia who have not  received prior treatment. The objective of this study was to evaluate its efficiency in Spain using a cost-utility analysis.

METHOD

Using a partitioned-survival analysis model adapted to the Spanish  context and based on three health states (progression-free survival, survival  after progression, and death), a simulation of the evolution of patients who  were candidates for initiating first-line treatment was conducted for a lifetime  time horizon. Venetoclax in combination with obinutuzumab was compared to  the most commonly used therapeutic options for these patients at the time of  study design: chlorambucil in combination with obinutuzumab, ibrutinib,  fludarabine in combination with cyclophosphamide and rituximab, and  bendamustine in combination with rituximab. In order to estimate survival  curves, efficacy data were derived from the CLL14 trial and a network meta- analysis. The  analysis was conducted from the perspective of the Spanish  National Healthcare System and included direct healthcare costs (i.e.  pharmacological costs and their administration), and those associated with the management of the disease and adverse events. The resource use was validated by an expert group. Quality of life data were used to estimate the  quality-adjusted life years obtained for each alternative. A threshold of  €25,000/quality-adjusted life years was used. The robustness of the model was evaluated using deterministic and probabilistic sensitivity analyses.

RESULTS

Venetoclax in combination with obinutuzumab was shown to be a  dominant alternative compared to the rest of the treatment alternatives, with a  lower cost per patient (€-67,869 compared to chlorambucil in combination  with obinutuzumab, €-375,952 compared to ibrutinib, €-61,996 compared to  fludarabine in combination with cyclophosphamide and rituximab, and €- 77,398 compared to bendamustine in combination with rituximab). It also had  a greater gain in quality-adjusted life years (0.551 quality-adjusted life years  gained compared to chlorambucil in combination with obinutuzumab and  ibrutinib, 1.639 quality-adjusted life years gained compared to fludarabine in  combination with cyclophosphamide and rituximab, and 1.186 quality-adjusted  life years gained compared to bendamustine in combination with  rituximab). Between 68% and 85% of the simulations performed in the  sensitivity analysis showed that venetoclax in combination with obinutuzumab  had lower costs and more quality-adjusted life years gained.

CONCLUSIONS

Venetoclax in combination with obinutuzumab is an efficient and  dominant alternative for treating previously untreated patients with chronic lymphocytic leukaemia compared to the available  alternatives and from the perspective of the Spanish National Health System.

Patient-reported outcomes and mobile applications. A review of their impact on patients' health outcomes

OBJECTIVE

To review the evidence of the mobile apps in collection patient- reported outcomes and their impact on health outcomes. Method: A review was conducted of the literature on apps aimed at collecting  patient-reported outcomes. Selected articles were required to consider the  apps' impact on patients' health outcomes. The search was carried out during  April 2021 in Pubmed and Embase using the search terms "app", "mobile  applications" , "patient-reported outcomes", "outcome assessment, health  care", and "quality of life", To be included articles had to be written in English  or Spanish and they were required to dwell on apps used by patients, family  members and/or caregivers that measured at least one health outcome. No  time restrictions were applied.

RESULTS

Of the 26 articles reviewed, 19 (73.1%) were clinical trials, 4  (15.4%) were quasi-experimental studies, and 3 (11.5%) were observational studies. A pharmacy department was involved in 4 studies  (15.4%), and 3 (11.5%), were carried out in Spain. The sample size ranged  from 14 to 411. Depending on the study population, the most frequent studies included cancer patients (42.3%) and patients with cardiovascular  diseases (26.9%). Most of the studies focused on measuring the impact of the app on the patients' quality of life (50.0%), control of clinical parameters  (46.2%), adherence (38.5%), and management of symptoms and/or reduction  of complications (26.9%). Overall efficacy in terms of the  percentage of studies where apps were found to result in a significant  improvement was 73.1%. The most heavily impacted patient-reported  outcomes were adherence, health-related quality of life and satisfaction.

CONCLUSIONS

There is emerging evidence that apps have a positive impact on  patients' health outcomes. These tools have shown to lead to an improvement  in the management of different conditions, with results showing a reduction in  complications rates and in the consumption of resources as well as better  adherence to medication and enhanced patient quality of life.

The Characteristics and Functionalities of Mobile Apps Aimed at Patients Diagnosed With Immune-Mediated Inflammatory Diseases: Systematic App Search

Background

Immune-mediated inflammatory diseases (IMIDs) are systemic conditions associated with a high social and health impact. New treatments have changed the prognosis of IMIDs and have increased patient autonomy in disease management. Mobile apps have enormous potential to improve health outcomes in patients with IMIDs. Although a large number of IMID apps are available, the app market is not regulated, and functionality and reliability remain uncertain.

Objective

Our aims are to review available apps for patients with IMIDs or caregivers and to describe the main characteristics and functionalities of these apps.

Methods

We performed an observational, cross-sectional, descriptive study of all apps for patients with IMIDs. Between April 5 and 14, 2021, we conducted a search of the App Store (iOS) and Play Store (Android) platforms. We used the names of the different IMIDs as search terms. The inclusion criteria were as follows: content related to IMIDs, English or Spanish language, and user population consisting of patients and health care consumers, including family and caregivers. The variables analyzed were as follows: app name, type of IMID, platform (Android or iOS), country of origin, language, category of the app, cost, date of the last update, size, downloads, author affiliation, and functionalities.

Results

We identified 713 apps in the initial search, and 243 apps met the criteria and were analyzed. Of these, 37% (n=90) were on Android, 27.2% (n=66) on iOS, and 35.8% (n=87) on both platforms. The most frequent categories were health and well-being/fitness apps (n=188, 48.5%) and medicine (n=82, 37.9%). A total of 211 (82.3%) apps were free. The mean time between the date of the analysis and the date of the most recent update was 18.5 (SD 19.3) months. Health care professionals were involved in the development of 100 (41.1%) apps. We found differences between Android and iOS in the mean time since the last update (16.2, SD 14.7 months vs 30.3, SD 25.7 months) and free apps (85.6% vs 75.8%; respectively). The functionalities were as follows: general information about lifestyles, nutrition, or exercises (n=135, 55.6%); specific information about the disease or treatment (n=102, 42%); recording of symptoms or adverse events (n=51, 21%); agenda/calendar (n=44, 18.1%); reminder medication (n=41, 16.9%); and recording of patient-reported outcomes (n=41, 16.9%). A total of 147 (60.5%) apps had more than one functionality.

Conclusions

IMID-related apps are heterogeneous in terms of functionality and reliability. Apps may be a useful complement to IMID care, especially inpatient education (their most frequent functionality). However, more than half of the IMID apps had not been developed by health care professionals or updated in the last year.

Information and communication technologies in Patients with Immune-Mediated Inflammatory Diseases: Cross-Sectional Survey (Preprint)

Background

Information and communication technologies (ICTs) are changing the traditional health care model and redefining personalized health. ICTs offer effective communication and real-time monitoring of patients and provide additional data to support clinical decision-making, improve the quality of care, and contribute to the empowerment of patients. However, evidence on the use of ICTs and digital preferences of immune-mediated inflammatory disease (IMID) patients is scarce.

Objective

The aim of this study is to describe the degree of use of ICTs in patients with IMIDs (including rheumatic diseases, inflammatory bowel diseases, and psoriasis), identify their needs, and analyze their interest in the use of apps as tools for better management of their disease.

Methods

A questionnaire was created by a multidisciplinary team including pharmacists, rheumatologists, gastroenterologists, dermatologists, and nurses with experience in ICTs applied to the field of IMID. The survey included 27 questions organized into 3 blocks: (1) sociodemographic characteristics, (2) ICT use for health-related information, and (3) patient expectations about mobile health.

Results

A total of 472 questionnaires were analyzed. Overall, 52.9% (250/472) of patients were diagnosed with a rheumatologic disease, 39.4% (186/472) with inflammatory bowel disease, and 12.3% (58/472) with psoriasis. The state of health was considered good by 45.6% (215/472) of patients. Patients were interested in staying informed about health issues in 86.9% (410/427) of cases and sought health-related information mainly from the internet (334/472, 70.8%) and health care professionals (318/472, 67.4%). Overall, 13.6% (64/472) did not trust the health information they found in internet. Of the patients, 42.8% (202/472) had a health app, and 42.2% (199/472) had found it on their own. Patients would like a health app to help mainly to manage appointments (281/472, 59.5%), obtain information about their diseases and treatments (274/472, 58.1%), and get in contact with health professionals (250/472, 53.0%). Overall, 90.0% (425/472) of patients reported they would use an app to manage their IMID if their health professional recommended it, and 58.0% (274/472) would pay or probably be willing to pay for it.

Conclusions

IMID patients were very interested in finding health-related information via ICTs, especially using smartphones and apps recommended by health professionals. Appointment management, advice on disease and treatment management, and personalized communication with health professionals were the most desired app features identified. Health professionals should play an essential role in recommending and validating these tools to ensure they are of high quality.

Mobile Apps for Hematological Conditions: Review and Content Analysis Using the Mobile App Rating Scale

Background

Hematological conditions are prevalent disorders that are associated with significant comorbidities and have a major impact on patient care. Concerning new tools for the care of these patients, the number of health apps aimed at hematological patients is growing. Currently, there are no quality analyses or classifications of apps for patients diagnosed with hematological conditions.

Objective

The aim of this study is to analyze the characteristics and quality of apps designed for patients diagnosed with hematological conditions by using the Mobile App Rating Scale (MARS).

Methods

We performed an observational, cross-sectional descriptive study of all smartphone apps for patients diagnosed with hematological conditions. A search was conducted in March 2021 using the following terms: anemia, blood cancer, blood disorder, hematological cancer, hematological malignancy, hematological tumor, hematology, hemophilia, hemorrhage, lymphoma, leukemia, multiple myeloma, thalassemia, thrombocytopenia, and thrombosis. The apps identified were downloaded and evaluated by 2 independent researchers. General characteristics were registered, and quality was analyzed using MARS scores. Interrater reliability was measured by using the Cohen κ coefficient.

Results

We identified 2100 apps in the initial search, and 4.19% (88/2100) of apps met the inclusion criteria and were analyzed. Of the 88 apps, 61% (54/88) were available on Android, 30% (26/88) were available on iOS, and 9% (8/88) were available on both platforms. Moreover, 7% (6/88) required payment, and 49% (43/88) were updated in the last year. Only 26% (23/88) of the apps were developed with the participation of health professionals. Most apps were informative (60/88, 68%), followed by preventive (23/88, 26%) and diagnostic (5/88, 6%). Most of the apps were intended for patients with anemia (23/88, 26%). The mean MARS score for the overall quality of the 88 apps was 3.03 (SD 1.14), ranging from 1.19 (lowest-rated app) to 4.86 (highest-rated app). Only 47% (41/88) of the apps obtained a MARS score of over 3 points (acceptable quality). Functionality was the best-rated section, followed by aesthetics, engagement, information, and app subjective quality. The five apps with the highest MARS score were the following: Multiple Myeloma Manager, Hodgkin Lymphoma Manager, Focus On Lymphoma, ALL Manager, and CLL Manager. The analysis by operating system, developer, and cost revealed statistically significant differences in MARS scores (P<.001, P<.001, and P=.049, respectively). The interrater agreement between the 2 reviewers was substantial (k=0.78).

Conclusions

There is great heterogeneity in the quality of apps for patients with hematological conditions. More than half of the apps do not meet acceptable criteria for quality and content. Most of them only provide information about the pathology, lacking interactivity and personalization options. The participation of health professionals in the development of these apps is low, although it is narrowly related to better quality.

Potential negative pharmacodynamic interaction of spironolactone and abiraterone in two prostate cancer patients

INTRODUCTION

Spironolactone when combined with abiraterone in metastatic castration-resistant prostate cancer (mCRPC) may theoretically exert androgenic properties, thereby compromising the therapeutic effectiveness of abiraterone.

CASE REPORT

Two patients with a medical history of cardiovascular disease and mCRPC combined spironolactone within the course of abiraterone regimen. The abiraterone-spironolactone interaction was identified using the Lexicomp® interaction tool (classified as risk C).

MANAGEMENT & OUTCOME

Spironolactone treatment was maintained as it was considered beneficial due to the cardiac condition. The prostate-specific antigen (PSA) levels started to rise when these two drugs were used together. Eventually, tumour progression was observed.

DISCUSSION

There is increasing evidence that spironolactone behaves as a selective androgen receptor modulator. Strategies to overcome abiraterone-spironolactone interaction could involve the use of eplerenone, although this drug is also controversial. The best strategy should imply a multidisciplinary evaluation by cardiologists and oncologists.

Potential and real drug interactions in patients treated with abiraterone or enzalutamide in clinical practice

BACKGROUND

Abiraterone and enzalutamide, androgen receptor pathway inhibitors (ARPI) for the treatment of metastatic castration-resistant prostate cancer (mCRPC), are at high risk of potential drug interactions (PDIs). We aimed to describe PDIs and their management, and triggered adverse events (AEs) in clinical practice.

METHODS

We conducted a cross-sectional study in mCRPC patients who started treatment with abiraterone or enzalutamide in a university hospital between August 1st, 2016 and July 31st, 2020. Lexicomp® was used to identify and analyze PDIs, and the clinical records to assess their management and the occurrence of AEs.

RESULTS

We included 173 patients: 36.8% and 93.0% of patients treated with abiraterone and enzalutamide, respectively, had at least 1 PDI. Globally, 6.3% of PDIs had X-risk (contraindication due to high probability of AE). Treatment was modified in 9.2% of patients and 9.8% suffered AEs due to PDIs. Factors associated with a higher risk of PDIs were polypharmacy (OR=41.0, p=0.003) and treatment with enzalutamide (OR=128.26, p< 0.001).

CONCLUSIONS

At least two-thirds of patients treated with ARPI suffered a PDI. Overall, abiraterone would have a more favorable PDI profile. Knowing these interaction profiles may be helpful to develop a more efficient therapeutic follow-up and to select the safest treatment.

Error Detection and Cost Savings With an Image-Based Workflow Management System Connected to a Computerized Prescription Order Entry Program for Antineoplastic Compounding

OBJECTIVE

The aim of the study was to analyze both the prevalence of errors with the implementation of an image-based workflow management system during the antineoplastic compounding process, and the estimated costs associated with the negative clinical outcome if the errors had not been intercepted.

METHODS

Three months after the implementation of Phocus Rx system at a hospital pharmacy department, the identification, classification (type, preparation stage, and cause), and potential severity degree (from negligible to catastrophic) of the errors intercepted were determined. The probability of an error causing an adverse event if it had reached the patient (from nil [0] to high [0.6]) and its consequences was estimated by a team of clinical pharmacists and physicians. Cost-effectiveness analysis from the hospital's perspective was performed.

RESULTS

Overall, 9872 antineoplastic medications were prepared using Phocus Rx. The total compounding error rate was 0.8% (n = 78, 56 [69.2%] were related to incorrect dose, 20 [28.2%] to incorrect drug preparation or conditioning technique, and 2 [2.6%] were wrong drugs). Approximately 70% of the detected errors were classified as undetectable via the previous verification practice, with 11.55% judged to be potentially severe (n = 9) and 51.3% moderate (n = 29). Likelihood of occurrence of an adverse event was medium (0.4) to high (0.6) for 37.2% of the errors. Estimated cost ratio and return on investment were €4.21 and 321%, respectively.

CONCLUSIONS

The implementation of Phocus Rx prevented antineoplastic preparation errors that would have reached the patient otherwise. In addition, acquisition of this technology was estimated to be cost-effective.

Thalidomide as treatment of refractory thoracic Rosai-Dorfman disease

WHAT IS KNOWN AND OBJECTIVE

Rosai-Dorfman disease (RDD) is an infrequent entity of unknown aetiology. Currently, there is no clear consensus on the treatment, and nothing has shown definitive safety and efficacy. We describe the case of a woman diagnosed with pulmonary RDD, who responded to thalidomide treatment after failure of four previous lines of systemic chemotherapy.

CASE DESCRIPTION

We present the case of a 74-year-old woman diagnosed with pulmonary RDD and autoimmune complications. We decided to use thalidomide as a rescue treatment after the failure of corticosteroids and several chemotherapies. Our patient achieved remission of the disease and remained stable for years.

WHAT IS NEW AND CONCLUSION

To the authors' knowledge, this is the first reported case in which thalidomide treatment induced remission in refractory pulmonary RDD. Thalidomide showed a rapid onset of action, with lasting responses, which could make it an exciting option for treating this life-threatening.

Medication guide for the perioperative management of oral antineoplastic agents in cancer patients

BACKGROUND

Oral antineoplastic agents (OAAs) are high-risk drugs that may increase the risk of bleeding, difficulty in wound healing, or produce alterations in coagulation and/or platelet aggregation. These aspects had to be highly considered throughout the entire perioperative process. Our aim was to create a comprehensive management medication guide based on reconciliation and dose adjustment recommendations for OAAs in patients undergoing a surgical intervention.

RESEARCH DESIGN AND METHODS

We analyzed all OAAs approved by the EMA in November 2020. We assessed data related to dose adjustment, drug reconciliation, coagulation disturbances, or anticoagulant interactions from the FDA and EMA summary of product characteristics.

RESULTS

We analyzed 67 OAAs. We identified that 51 (76.2%) OAAs can produce alteration in the platelet count, 12 (17.9%) affect the wound healing and recovery process, and 32 (47.8%) require control and monitoring in case of combination with anticoagulants. Only 13 (19.4%) OAAs, most of them antiangiogenics, have specific recommendations for temporary suspension before surgery.

CONCLUSIONS

Most OAAs require perioperative monitoring. This review can serve as an easy (simple, effective) tool to help healthcare professionals involved in patient care to manage OAAs during the perioperative process.

Chimeric Antigen Receptor T Cell Therapy Management and Safety: A Practical Tool From a Multidisciplinary Team Perspective

Purpose

The use process for chimeric antigen receptor T (CAR-T) cell drugs is complex and has been associated with a number of potentially severe complications, which requires management by a multidisciplinary team. Pharmacists are a key element in the team and have roles and responsibilities. Our objective was to develop a structured and practical guide that supports hospital pharmacist responsibilities and defines specific activities in a CAR-T cell therapy program, specifically in Europe.

Methods

A literature review was performed, and the recommendations related to pharmacy practice in CAR-T therapy programs were analyzed. A multidisciplinary team was assembled, and meetings were held to address the key tasks in the CAR-T cells’ management process and to create the guide, based on national and international recommendations and in expert’s opinions.

Results

The multidisciplinary team defined the following key tasks and issued recommendations to improve patient safety, treatment efficacy, and quality: patient selection and evaluation, CAR-T cell drug order to manufacturer, apheresis and material shipment, reception of CAR-T cell drug and storing, CAR-T cell drug prescription and pharmacy verification, CAR-T cell drug thawing and dispensing, CAR-T cell drug administration, patient education, pharmacovigilance and monitoring and outcomes’ record and evaluation. In each task the pharmacist’s role and how it can improve patient care are defined. A checklist was created to guarantee the compliance of standard operating procedures approved in the institution to manage CAR-T cell therapy and as a tool to collect required data for outcomes’ record and evaluation.

Conclusion

This article provides a consensus set of safety recommendations regarding CAR-T therapy management in clinical practice, easily implementable by other institutions in the European setting. The guide identifies key steps where the involvement of hospital pharmacists would improve the safety and quality of the process and is a support guide to standardize hospital pharmacists’ responsibilities within the multidisciplinary team.

Assessment of diarrhea as side effect of oral targeted antineoplastic agents in clinical practice

BACKGROUND

Diarrhea is one of the most frequent class adverse events associated with targeted oral antineoplastic agents (OAAs). Our objective was to analyze the incidence, characteristics, and severity of diarrhea in cancer patients in clinical practice.

METHODS

An observational, longitudinal, and prospective study of cancer outpatients treated with targeted OAAs was carried out in a tertiary hospital. Targed OAAs analyzed were anaplastic lymphoma kinase inhibitors, BCR-ABL inhibitors, cyclin-dependent kinase inhibitors, epidermal growth factor receptor inhibitors, mTOR inhibitors, poly (ADP-ribose) polymerase inhibitors, and vascular endothelial growth factor receptor inhibitors. Patients were given a data collection form to record daily the number, severity (CTCAE version 5.0), and characteristics of stools during the first 30 days of treatment with OAAs. Multivariate analysis was performed to identify risk factors associated with the incidence of diarrhea.

RESULTS

We analyzed 240 patients, of whom 28.7% experienced diarrhea (25.4% grades 1-2 and 3.3% grades 3-4). Patients treated with EGFR and VEGFR inhibitors had a higher incidence of diarrhea. The multivariate analysis revealed that taking the OAA with food was associated with a lower risk of diarrhea (OR = 0.404 [0.205-0.956], p = 0.038).

CONCLUSIONS

More than a third of patients in treatment with OAAs presented diarrhea (any grade), and 22.1% of stools were semi-liquid/liquid. In multivariate analysis, taking the OAA on an empty stomach was associated with a statistically significant increase in the incidence of diarrhea.

Aggressiveness of end-of-life cancer care: what happens in clinical practice?

PURPOSE

End-of-life cancer care varies widely, and very few centers evaluate it systematically. Our objective was to assess indicators of the aggressiveness of end-of-life cancer care in clinical practice.

METHODS

An observational, longitudinal, and retrospective cohort study was conducted at a tertiary hospital. Eligible patients were at least 18 years old, had a solid tumor, were followed up by the Oncology Department, and had died because of cancer or associated complications during 2017. We used the criteria of Earle et al. (J Clin Oncol 21(6):1133-1138, 2003) to assess the aggressiveness of care. Multivariate logistic regression analyses were performed to characterize factors associated with aggressiveness of therapy.

RESULTS

The study population comprised 684 patients. Eighty-eight patients (12.9%) received anti-cancer treatment during the last 14 days of their lives, and 62 patients (9.1%) started a new treatment line in the last 30 days. During the last month of life, 102 patients (14.9%) visited the ER, 80 patients (11.7%) were hospitalized more than once, and 26 (3.8%) were admitted to the ICU. A total of 326 patients (47.7%) died in the acute care unit. A total of 417 patients (61.0%) were followed by the Palliative Care Unit, and in 54 cases (13.0%), this care started during the last 3 days of life.

CONCLUSIONS

The use of anti-cancer therapies and health care services in our clinical practice, except for the ICU, did not meet the Earle criteria for high-quality care. Concerning hospice care, more than half of the patients received hospice services before death, although in some cases, this care started close to the time of death.

Effect of a Mobile App for the Pharmacotherapeutic Follow-Up of Patients With Cancer on Their Health Outcomes: Quasi-Experimental Study

Background

Oral antineoplastic agents (OAAs) have revolutionized cancer management. However, they have been reported with adverse side effects and drug-drug interactions. Moreover, patient adherence to OAA treatment is critical. Mobile apps can enable remote and real-time pharmacotherapeutic monitoring of patients, while also promoting patient autonomy in their health care.

Objective

The primary objective was to analyze the effect of using a mobile app for the follow-up of patients with oncohematological malignancies undergoing treatment with OAAs on their health outcomes. The secondary objectives were to analyze the role of the app in communication with health care professionals and patient satisfaction with the app.

Methods

We performed a comparative, quasi-experimental study based on a prepost intervention with 101 patients (control group, n=51, traditional pharmacotherapeutic follow-up vs intervention group, n=50, follow-up through e-OncoSalud, a custom-designed app that promotes follow-up at home and the safety of patients receiving OAAs). The effect of this app on drug safety, adherence to treatment, and quality of life was evaluated.

Results

With regard to drug safety, 73% (37/51) of the patients in the control group and 70% (35/50) of the patients in the intervention group (P=.01) presented with drug-related problems. The probability of detecting an insufficiently treated health problem in the intervention group was significantly higher than that in the control group (P=.04). The proportion of patients who presented with side effects in the intervention group was significantly lower than that in the control group (P>.99). In the control group, 49% (25/51) of the patients consumed some health resources during the first 6 months of treatment compared with 36% (18/50) of the patients in the intervention group (P=.76). Adherence to treatment was 97.6% (SD 7.9) in the intervention group, which was significantly higher than that in the control group (92.9% [SD 10.0]; P=.02). The EuroQol-5D in the intervention group yielded a mean (SD) index of 0.875 (0.156), which was significantly higher than that in the control group (0.741 [0.177]; P<.001). Approximately 60% (29/50) of the patients used the messaging module to communicate with pharmacists. The most frequent types of messages were acknowledgments (77/283, 27.2%), doubts about contraindications and interactions with OAAs (70/283, 24.7%), and consultations for adverse reactions to treatment (39/283, 13.8%). The satisfaction with the app survey conducted in the intervention group yielded an overall mean (SD) score of 9.1 (0.4) out of 10.

Conclusions

Use of e-OncoSalud for the real-time follow-up of patients receiving OAAs facilitated the optimization of some health outcomes. The intervention group had significantly higher health-related quality of life and adherence to treatment than the control group. Further, the probability of the intervention group presenting with side effects was significantly lower than that of the control group.

Standardizing Health Outcomes for Lung Cancer. Adaptation of the International Consortium for Health Outcomes Measurement Set to the Spanish Setting

Purpose: Lung cancer (LC) and its treatment impose a significant burden on patients' life. However, patient-centered outcomes are rarely collected during patient follow-up. Filling this gap, the International Consortium for Health Outcomes Measurement (ICHOM) developed a standard set of variables for newly diagnosed LC patients. In order to facilitate the use of this standard set, the project aims to adapt it to the Spanish setting.

Methods: The variables (instrument and periodicity) to be included in Spanish standard set were selected through consensus during 4 nominal groups (13 oncologists, 14 hospital pharmacists, 4 hospital managers and 3 LC patients), under the supervision of a Scientific Committee (1 oncologist, 3 hospital pharmacists, 2 LC patients advocates).

Results: The variables agreed upon included: (1) case-mix: demographic [age, sex, education and social-family support], clinical [weight loss, smoking status, comorbidities (Charlson index), pulmonary function (FEV-1)], tumor [histology, clinical, and pathological stage (TNM), EGFR, ALK, ROS-1, PD-L1] and treatment factors [intent and completion] and (2) outcomes: degree of health [performance status (ECOG) and quality-of-life (EQ-5D, LCSS)], survival [overall survival and cause of death], quality of death [place of death, end-of-life care and palliative care, death aligned with living will], treatment complications, and others [date of diagnosis and treatment initiation, productivity loss (sick leave)].

Conclusion: The adaptation of ICHOM standard set to the Spanish setting pave the way to standardize the collection of variables in LC.

Features and Functionalities of Smartphone Apps Related to COVID-19: Systematic Search in App Stores and Content Analysis

Background

Knowledge of the quantity and quality of apps related to coronavirus disease (COVID-19) is lacking. In addition, no directory has been established listing all the apps developed to address the COVID-19 pandemic.

Objective

The aim of this study was to identify smartphone apps designed to address the COVID-19 pandemic and to analyze their characteristics.

Methods

We performed an observational, cross-sectional, descriptive study of all smartphone apps associated with COVID-19. Between April 27 and May 2, 2020, we searched the App Store (iOS) and Google Play Store (Android) for COVID-19 apps. The search terms used were coronavirus, COVID-19, and SARS-COV-2. The apps were downloaded and evaluated. The variables analyzed were name, platform, country, language, category, cost, update date, size, version, number of downloads, developer, and purpose. Purpose was further classified into the following categories: news, general information, self-diagnosis, contact tracing, notices to contacts, notification of close cases, awareness, helplines, monitoring of clinical parameters, recording of symptoms and treatment, and messaging with health care professionals.

Results

We identified 114 apps on the investigated platforms. Of these, 62/114 (54.4%) were on Android and 52/114 (45.6%) were on iOS. Of the 114 apps, 37 (32.5%) were developed in Europe, 32 (28.1%) in Asia, and 30 (26.3%) in North America. The most frequent languages were English (65/114, 57.0%), Spanish (34/114, 29.8%), and Chinese (14/114, 12.3%). The most common categories were health and well-being/fitness apps (41/114, 41.2%) and medicine apps (43/114, 37.7%). Of the 114 apps, 113 (99.1%) were free. The mean time between the date of the analysis and the date of the last update was 11.1 days (SD 11.0). Overall, 95 of the 114 apps (83.3%) were intended for the general population, 99 apps (7.9%) were intended for health professionals, and 3 apps (2.6%) were intended for both. Regarding the type of developer, 64/114 apps (56.1%) were developed by governments; 42/114 (64.1%) were developed by national governments, and 23/114 (35.9%) were developed by regional governments. The apps with the highest number of downloads (100,000+) were developed by governments (P=.13), except for the World Health Organization app (500,000+). The purposes of the apps available in Western languages (107/114, 93.9%) were determined; the most common purposes were general information about COVID-19 (66, 64.0%), COVID-19 news (53, 51.0%), recording of symptoms (53, 51.0%), and contact tracing (51, 47.7%). More than one purpose was identified for 99/107 apps (92.5%).

Conclusions

This paper offers a comprehensive and unique review of all available COVID-19 apps. Governments have adopted these tools during the pandemic, and more than half of the apps were developed by government agencies. The most common purposes of the apps are providing information on the numbers of infected, recovered, and deceased patients, recording of symptoms, and contact tracing.

Novel mobile application for direct communication between pharmacists and patients treated with oral antineoplastic agents

PURPOSE

Initial experience with use of a smartphone application to enhance communication with and home monitoring of hematology/oncology patients under treatment with oral antineoplastic agents (OAAs) is described.

SUMMARY

Broad use of OAAs is changing the landscape of hematology/oncology patient care, with this form of therapy giving patients greater autonomy but also raising concerns about correct OAA administration and management of adverse effects (AEs) or interactions. Information and communication technologies, specifically mobile health technologies, are ideal tools in this new environment. A multidisciplinary team at a large hospital in Spain developed a smartphone application for patients receiving OAA therapy that consists of 5 modules or functionalities: (1) a treatment agenda, or electronic journal of patient activity, including medication use; (2) a treatment record; (3) continuous recording of vital signs (blood pressure and temperature), health-related quality of life, and AEs, with management of AEs based on an algorithm that displays different recommendations according to AE severity; (4) 2-way messaging capability; and (5) information and links to websites of interest. From June through November 2017, 37 patients downloaded and used the application. About two-thirds (68%) of the patients sent a total of 182 messages to the pharmacist on duty; 58% of the patients registered at least 1 AE. The mean time of registration of the first AE after initiation of OAA therapy was 8 days. As a result of patient use of the application, 2 emergency room visits were avoided and 3 patients were referred to a general practitioner.

CONCLUSION

The application has allowed real-time monitoring of patients treated with OAAs. This new patient-pharmacist communication channel has facilitated the early detection of AEs, contributing to the safety of treatment and patient satisfaction with healthcare.

Acute pancreatitis in a patient treated with imatinib and gefitinib

INTRODUCTION

Use of oral antineoplastic agents (OAAs) has increased significantly in recent years. OAAs currently represent 30-50% of all cancer treatments. Drug interactions are the most frequent drug-related problem affecting OAAs. We describe the case of a patient who presented acute pancreatitis, possibly induced by the concomitant use of imatinib and gefitinib.

CASE REPORT

A female patient received imatinib and gefitinib for the treatment of chronic myeloid leukemia and lung adenocarcinoma, respectively. Liver function and pancreatic enzyme values gradually worsened after initiation of imatinib, and the patient was diagnosed with acute pancreatitis.

MANAGEMENT AND OUTCOMES

Imatinib was discontinued owing to pancreatic toxicity. Gefitinib was subsequently discontinued owing to tumor progression. The patient received supportive measures for pancreatitis, although she eventually died 3 months after the onset of symptoms.

DISCUSSION

To our knowledge, this is the first case in the medical literature of acute pancreatitis possibly induced by an interaction between imatinib and gefitinib. The interaction most likely arose because imatinib is a CYP2D6 inhibitor and could therefore impair the metabolism of gefitinib (a CYP2D6 substrate) and increase its serum concentration. This interaction is extremely rare. However, due to its severity, hepatic and pancreatic function should be carefully monitored in patients treated with imatinib and/or gefitinib and other inhibitors or inducers of CYP2D6 and CYP3A4.

Tocilizumab as salvage treatment of refractory pulmonary acute graft-versus-host disease

INTRODUCTION

Acute graft-versus-host disease GVHD (aGVHD) is the main complication during the first months after bone transplantation. Steroid therapy is clearly the upfront established treatment for aGVHD. However, there are patients with partial response to steroid treatment and steroid-refractory cases. For those patients, a vast number of therapeutic options have emerged, although the evidence is scarce.

CASE REPORT

We report the use of tocilizumab as salvage treatment in a patient with corticosteroid refractory pulmonary aGVHD that was admitted to the critical care unit for respiratory support measures.

MANAGEMENT & OUTCOME

We decided to use tocilizumab as rescue treatment, after failure of corticosteroid treatment, standard treatment with broad-spectrum antibiotics and etanercept. The patient showed a remarkable clinical improvement two days after first infusion and a total resolution of the symptomatology with normalization of the spirometry tests after 4 weeks of the administration of tocilizumab.

DISCUSSION

To the authors' knowledge, this is the first case that describes the effective and safe use of tocilizumab as a rescue treatment in a patient with steroid-refractory pulmonary aGVHD. It showed a rapid onset of action and a favorable safety profile, which could make it an interesting option for the treatment of this potentially fatal complication.

Assessing Apps for Patients with Genitourinary Tumors Using the Mobile Application Rating Scale (MARS): Systematic Search in App Stores and Content Analysis

BACKGROUND

The large number of available cancer apps and their impact on the population necessitates a transparent, objective, and comprehensive evaluation by app experts, health care professionals, and users. To date, there have been no analyses or classifications of apps for patients with genitourinary cancers, which are among the most prevalent types of cancer.

OBJECTIVE

The objective of our study was to analyze the quality of apps for patients diagnosed with genitourinary cancers using the Mobile Application Rating Scale (MARS) and identify high-quality apps.

METHODS

We performed an observational cross-sectional descriptive study of all smartphone apps for patients diagnosed with genitourinary cancers available on iOS and Android platforms. In July 2019, we searched for all available apps for patients with genitourinary cancers (bladder, prostate, cervical, uterine, endometrial, kidney, testicular, and vulvar) or their caregivers. Apps were downloaded and evaluated, and the general characteristics were entered into a database. The evaluation was performed by 2 independent researchers using the MARS questionnaire, which rates 23 evaluation criteria clustered in 5 domains (Engagement, Functionality, Esthetics, Information, and Subjective Quality) on a scale from 1 to 5.

RESULTS

In total, 46 apps were analyzed. Of these, 31 (67%) were available on Android, 6 (13%) on iOS, and 9 (20%) on both platforms. The apps were free in 89% of cases (41/46), and 61% (28/46) had been updated in the previous year. The apps were intended for prostate cancer in 30% of cases (14/46) and cervical cancer in 17% (8/46). The apps were mainly informative (63%, 29/46), preventive (24%, 11/46), and diagnostic (13%, 6/46). Only 7/46 apps (15%) were developed by health care organizations. The mean MARS score for the overall quality of the 46 apps was 2.98 (SD 0.77), with a maximum of 4.63 and a minimum of 1.95. Functionality scores were quite similar for most of the apps, with the greatest differences in Engagement and Esthetics, which showed acceptable scores in one-third of the apps. The 5 apps with the highest MARS score were the following: "Bladder cancer manager," "Kidney cancer manager," "My prostate cancer manager," "Target Ovarian Cancer Symptoms Diary," and "My Cancer Coach." We observed statistically significant differences in the MARS score between the operating systems and the developer types (P<.001 and P=.01, respectively), but not for cost (P=.62).

CONCLUSIONS

MARS is a helpful methodology to decide which apps can be prescribed to patients and to identify which features should be addressed to improve these tools. Most of the apps designed for patients with genitourinary cancers only try to provide data about the disease, without coherent interactivity. The participation of health professionals in the development of these apps is low; nevertheless, we observed that both the participation of health professionals and regular updates were correlated with quality.

Potential drug interactions between targeted oral antineoplastic agents and concomitant medication in clinical practice

OBJECTIVES

Our objective was to analyze potential drug interactions (PDIs) between targeted OAAs and concomitant therapy in clinical practice.

METHODS

A cross-sectional observational study was performed in cancer outpatients who started treatment with a targeted OAA between 1 December 2015 and 31 May 2019. PDIs were analyzed using the Lexicomp® and the database About Herbs®. PDIs were classified according to severity, risk, and reliability ratings and their underlying mechanism. Univariate and multivariate analysis were performed to identify risk factors associated with PDIs.

RESULTS

A total of 881 patients were included, of whom 50.9% had at least 1 PDI between the OAA and the concomitant medication. The factors associated with a higher risk of PDIs were polypharmacy (≥5 concomitant medicines) (OR = 3.64 (2.54-5.20), p < 0.001), type of tumor (prostate cancer [OR = not available, p < 0.001], chronic myelogenous leukemia [OR = 5.10 (1.08-24.05), p = 0.040], sarcoma [OR = 4.97 (1.05-23.55), p = 0.043]), and treatment with hormone therapies (OR = not available, p < 0.001).

CONCLUSION

A search of PDIs should be prioritized, especially in patients receiving targeted OAAs with risk factors, such as polymedication, prostate cancer, chronic myelogenous leukemia, sarcoma, and treatment with hormone therapies.

Risks and medication errors analysis to evaluate the impact of a chemotherapy compounding workflow management system on cancer patients' safety

A failure modes, effects and criticality analysis was supported by an observational medication error rate study to analyze the impact of Phocus Rx^®, a new image-based workflow software system, on chemotherapy compounding error rates. Residual risks that should be a target for additional action were identified and prioritized and pharmacy staff satisfaction with the new system was evaluated. In total, 16 potential failure modes were recognized in the pre-implementation phase and 21 after Phocus Rx^® implementation. The total reduction of the criticality index was 67 percent, with a reduction of 46 percent in material preparation, 76 percent in drug production and 48 percent in quality control subprocesses. The relative risk reduction of compounding error rate was 63 percent after the implementation of Phocus Rx^®, from 0.045 to 0.017 percent. The high-priority recommendations defined were identification of the product with batch and expiration date from scanned bidimensional barcodes on drug vials and process improvements in image-based quality control. Overall satisfaction index was 8.30 (SD 1.06) for technicians and 8.56 (SD 1.42) for pharmacists (p = 0.655). The introduction of a new workflow management software system was an effective approach to increasing safety in the compounding procedures in the pharmacy department, according to the failure modes, effects and criticality analysis method.

Development and Evaluation of a Clinical Decision Support System to Improve Medication Safety

BACKGROUND

Clinical decision support systems (CDSSs) are a good strategy for preventing medication errors and reducing the incidence and severity of adverse drug events (ADEs). However, these systems are not very effective and are subject to multiple limitations that prevent their implementation in clinical practice.

OBJECTIVES

The objective of this study was to evaluate the effectiveness of an advanced CDSS, HIGEA, which generates alerts based on predefined clinical rules to identify patients at risk of an ADE.

METHODS

A multidisciplinary team defined the system and the clinical rules focusing on medication errors commonly encountered in clinical practice. Four intervention programs were defined: (1) dose adjustment in renal impairment; (2) adjustment of anticoagulation/antiplatelet therapy; (3) detection of biochemical/hematologic toxicities; and (4) therapeutic drug monitoring. We performed a 6-month observational prospective study to analyze the effectiveness of these clinical rules by calculating the positive predictive value (PPV).

RESULTS

The team defined 211 clinical rules. During the study period, HIGEA generated 1,086 alerts (8.9 alerts per working day), which were reviewed by pharmacists. Fifty-one percent (554/1,086) of alerts generated an intervention to prevent a possible ADE; of these, 66% (368/554) required a documented modification to therapy owing to a real prescription error intercepted. The intervention program that induced the highest number of modifications to therapy was the dose adjustment in renal impairment program (PPV = 0.51), followed by the adjustment of anticoagulation/antiplatelet therapy program (PPV = 0.24). The percentage of accepted interventions was similar in surgical units (68%), medical units (67%), and critical care units (63%).

CONCLUSION

Our study offers evidence that HIGEA is highly effective in preventing potential ADEs at the prescription stage.

Oral antineoplastic agents: assessment of safety and dose adjustments in clinical practice

Objectives: Although the safety profile of oral antineoplastic agents (OAAs) is better than that of classic chemotherapy, the rate of severe adverse events (AEs) is high. The objective was to assess the reasons for adjustments to treatment with OAAs during the first 100 days of treatment. Methods: The authors performed a prospective observational study of cancer outpatients who initiated OAAs between November 2015 and October 2017. Dose reductions and treatment interruptions were closely followed-up during the first 100 days after the beginning of treatment with an OAA. The authors described the different safety profile of different OAA classes. Results: The authors included 443 patients (31 different OAA assessed), of whom 53.0% required their OAA to be adjusted during the first 100 days of treatment. A total of 151 patients required dose reductions and/or interruptions of OAAs owing to AEs. The authors identified 203 AEs in these patients. Treatment with sorafenib, lower ECOG performance status, and first-line treatment were associated with a higher proportion of treatment adjustments due to AEs. Conclusion: These results in clinical practice could be a first approach to help healthcare professionals to design patient monitoring programs by identifying priority patients and drugs, and remarks the importance of pharmacovigilance in OAAs.

Design of the functional requirements of a smartphone app for patients receiving oral antineoplastic agents: The e-OncoSalud® app

Objective

To design a mobile app based on the needs of the onco-hematological patient receiving oral antineoplastic agents.

Methods

A multidisciplinary working group (pharmacy–oncology–hematology) was created to design the app. The study was developed in three phases: first, we analyzed the features of patients receiving oral antineoplastic agents. We then analyzed available apps for cancer patients. Finally, we designed the app's functionalities.

Results

We included 51 patients with middle-advanced age (68.7 years (SD=10.7)). They were polymedicated (mean: 5.3 (SD = 2.7), with numerous drug–drug interactions and adverse effects (all patients presented adverse effects). We then analyzed 166 apps. Most apps had more than one use, the most frequent being information (39.8%) and diagnosis (38.6%). Ten apps (6%) were for registering and monitoring treatment and adverse effects. Almost half of the apps (48.8%) were developed by healthcare organizations. Finally, we designed an app (e-OncoSalud®) with the following functionalities: (a) agenda; (b) treatment and drug interactions checker; (c) continuous recording of self-controls (weight, blood pressure, general condition) and adverse effects. The management of the adverse effects are based on an algorithm which provides different recommendations according to the adverse effects severity; (d) patient–pharmacist messaging in real-time; (e) education.

Conclusions

After analysis of the main problems affecting these patients and the needs not covered by the existing apps, we designed e-OncoSalud®. It integrates relevant information about their treatment, focused on drug interactions identification and the prevention, and management of adverse effects.

Robotic dispensing improves patient safety, inventory management, and staff satisfaction in an outpatient hospital pharmacy

RATIONALE, AIMS AND OBJECTIVES

Implementation of robotic systems in outpatient hospital pharmacies is uncommon. Other than cost, 1 of the barriers to widespread adoption is the lack of definitive evidence that this technology actually reduces dispensing errors and improves inventory management.

OBJECTIVE

To identify the frequency of medication dispensing errors before and after the implementation of a robotic original pack dispensing system in an outpatient hospital pharmacy and to analyse the impact of this system on the quality of stock management and staff satisfaction.

METHODS

A prospective before-and-after medication error study was performed using a disguised observation technique. Several indicators of stock management and staff satisfaction were monitored. Drugs were dispensed manually by technicians using a barcode-controlled system (preimplementation phase) or the dispensing robot ROWA Vmax (ARX) (postimplementation phase). As not all drugs could be handled by the robot, residual manual dispensing was also used.

RESULTS

The dispensing error rate was reduced from 1.31% of prescriptions (43/3284) to 0.63% (19/3004) (relative risk reduction [RRR], 51.7%; 95% CI, 17.3% to 71.8%). The error rate decreased up to 0.12% (3/2496) (RRR, 90.8%; 95% CI, 70.4% to 97.1%) if errors during residual manual dispensing were excluded. The stock-out ratio was reduced from 0.85% to 0.17% (RRR, 80.5%; 95% CI, 49.5% to 92.5%). Daily staff time (median) in stock management was reduced by 59.3% (from 1 hour 36 minutes to 39 minutes). High level of staff satisfaction with this technology was achieved, although it was slightly higher in the group of pharmacists compared to technicians (8.63 ± 0.7 vs 7.78 ± 0.7, P = .046).

CONCLUSION

The implementation of a robotic original pack dispensing system substantially decreased the rate of dispensing errors and optimized stock management. Minimizing the number of drugs out of the dispensing robot is critical when attempting to maximize the benefits of its implementation.

Oncology Patient Interest in the Use of New Technologies to Manage Their Disease: Cross-Sectional Survey

Background

Information and communication technologies (ICTs) in oncology can revolutionize the medical care of cancer patients. ICTs can promote patients’ empowerment and real-time disease monitoring. There is limited information about the impact of ICTs in cancer patients or their level of interest in using these tools for greater management of their condition.

Objective

This study aimed to understand the ICT usage profile in hematology-oncology patients to identify their needs and determine their level of interest in these technologies as a means of managing their disease.

Methods

A 28-item questionnaire was drawn up by a multidisciplinary team including pharmacists and oncologists. The questions were organized into 3 blocks, which were as follows: block A—sociodemographic characteristics; block B—use of ICTs when searching for health-related information; and block C—usage preferences for health apps. Hematology-oncology patients receiving treatment between May and July 2017 were included. A paper copy of the questionnaire was handed over to patients in either the day hospital or the pharmaceutical care consultancy in pharmacy services.

Results

A total of 650 questionnaires were handed out, with a participation of 94.0% (611/650). Patient sociodemographic characteristics were as follows: mean age was 57.8 years (age range: 19-91). Of 611 participants, 40.7% (249/611) had a university education, and 45.1% (276/611) of participants reported their overall state of health to be good. Results from use of ICTs when searching for health-related information were as follows: 87.1% (532/611) of participants were interested in being informed about health-related matters. Of all participants, 75.5% (532/611) sought information from health professionals and 61.3% (375/611) on the internet. Before going to their doctor’s appointment, 21.8% (133/611) of patients looked up information about their disease or treatment on the internet. This access to the internet rose to 50.9% (311/611) after their first medical appointment with their oncologist. Usage preferences for health apps were as follows: 82.7% (505/611) had a smartphone, whereas 20.3% (124/611) had a health app installed. Overall, 81.5% (498/611) would use an app if their health professional recommended it to them, but 39.6% (242/611) were not willing to pay for it.

Conclusions

The hematology-oncology patients showed a great deal of interest in searching for health-related information by means of ICTs, especially using smartphones and apps. The issues that drew the most interest in terms of apps were appointment management, advice on disease management, and communication with health professionals. Free access to these features and the recommendation by a health professional are important factors when it comes to their use. Therefore, the health care provider is a key element in the recommendation of ICTs, providing their knowledge and experience concerning their correct usage.

Association between clinical factors and dose modification strategies in the treatment with ustekinumab for moderate-to-severe plaque psoriasis

PURPOSE

The aim of this study was to identify clinical factors associated with dose reduction and dose escalation in the treatment with ustekinumab in patients with moderate-to-severe plaque psoriasis.

MATERIALS AND METHODS

An observational, longitudinal and retrospective study was conducted using patients with moderate-to-severe plaque psoriasis. We reviewed clinical histories and variables were recorded on a database (patients' characteristics, pharmacotherapeutics, effectiveness and safety). We evaluated correlation between dose reduction, dose escalation and used dose with other variables.

RESULTS

Of the study's 62 patients, Ustekinumab dose was adjusted in 45.2% (22.6% with reduced doses and 22.6% with increased doses). We found a statistically significant correlation between extending the dosing interval and the absence of psoriatic arthritis, no concomitant systemic therapies, treatment time with ustekinumab, lower PASI at week 28 and achieving PASI75 at week 28. There was also a statistically significant correlation between dose escalation and diabetes mellitus, psoriatic arthritis, prior biological treatments, concomitant systemic therapies, concomitant phototherapy and not achieving PASI75 at week 28.

CONCLUSIONS

Dose-reduction strategies would increase ustekinumab efficiency in patients that achieve PASI 75 without psoriatic arthritis, diabetes mellitus, previous BT and concomitant treatment with conventional systemic drugs.

Twelve weeks of ombitasvir/paritaprevir/r and dasabuvir without ribavirin is effective and safe in the treatment of patients with HCV genotype 1b infection and compensated cirrhosis: results from a real-world cohort study

OBJECTIVE

To explore the effectiveness and safety of ombitasvir/paritaprevir/ritonavir and dasabuvir (OBV/PTV/r+DSV) for 12 weeks without ribavirin in adults with chronic HCV genotype 1b infection and compensated cirrhosis.

METHODS

Observational study of a prospective cohort of adult patients with HCV genotype 1b infection and compensated cirrhosis who received 12 weeks of OBV/PTV/r and DSV without ribavirin. Effectiveness was assessed by recording the percentage of patients achieving sustained virological response at week 12 post-treatment (SVR12). Safety outcomes were based on the incidence of adverse events.

RESULTS

Seventy-eight patients were included. The SVR12 rate was 96.1% (95%CI 89.2-99.2). Adverse events were recorded in 78.0% of patients. Of these, 97.7% were grade 1/2. One patient discontinued treatment prematurely owing to adverse events. Eighty-six interactions were detected in 43 patients (55.1%). Overall, 81.4% of interactions required close monitoring, alteration of drug dosage, or timing of administration. In 7.0% of cases, the interactions arose from contraindications that required the suspension of the concomitant drug. In 11.6% of cases, medicinal plants or foods were withdrawn.

CONCLUSIONS

The simplified regimen of OBV/PTV/r+DSV administered for 12 weeks is effective and safe in patients with chronic HCV genotype 1b infection and compensated cirrhosis. No adverse reactions related to drug-drug interactions were recorded.

Inadequate response to imatinib treatment in chronic myeloid leukemia due to a drug interaction with phenytoin

Imatinib mesylate and the newer BCR-ABL tyrosine kinase inhibitors are the standard therapy for chronic myeloid leukemia. Although these are remarkably effective drugs, some mechanisms of resistance have been identified including drug-to-drug interactions. Here we present the case of a chronic myeloid leukemia patient with an inadequate response to imatinib due to concurrent phenytoin administration. Conspicuously low imatinib plasma trough levels were documented. Imatinib dose was increased from 400 to 800 mg with good response. In conclusion, drug-to-drug interactions should be ruled out in cases of resistance to tyrosine kinase inhibitor treatment. Potent inducers of cytochrome P450 isoenzyme CYP3A4, as phenytoin, could induce inadequate responses due to increased imatinib clearance and low imatinib trough plasma levels. Thus, this interaction should be avoided. When this is not possible, dose escalation of imatinib and measurement of plasma levels, if available, is recommended.

Eosinophilia secondary to lenalidomide therapy

WHAT IS KNOWN AND OBJECTIVE

Limited data are available on eosinophilia as a drug adverse event. We describe a case of eosinophilia from lenalidomide therapy.

CASE DESCRIPTION

A 50-year-old woman received lenalidomide, dexamethasone and cyclophosphamide as POEMS syndrome treatment. Eosinophil count rose during lenalidomide treatment and decreased in the periods off treatment. Naranjo nomogram suggested a probable association between the use of lenalidomide and eosinophilia.

WHAT IS NEW AND CONCLUSION

Eosinophilia has rarely been described with lenalidomide. This case shows a clear temporal relationship between lenalidomide and eosinophilia.

Severe liver toxicity in a chronic myeloid leukemia patient probably induced by a drug interaction between imatinib and sertraline

Our objective is to describe a chronic myeloid leukemia patient with a severe liver toxicity likely due to a drug-drug interaction between imatinib and sertraline. The patient started treatment with sertraline three months after starting imatinib. From the beginning of sertraline treatment, the patient developed vomiting, and five weeks later she developed a severe hepatic failure and was admitted to the hospital. The Naranjo nomogram showed a probable correlation between this adverse effect and the interaction between imatinib and sertraline. This interaction is extremely rare and the mechanism of action is not clear; it could be a mix of pharmacokinetic and pharmacodynamic processes. To our knowledge, this is the first case in medical literature of a severe liver toxicity due to an interaction between imatinib and sertraline. This interaction is also not described in the main secondary data sources, such as Lexicomp® and Micromedex®. However, due to the severity of this event, the hepatic function should be carefully monitored in patients treated with imatinib and sertraline.
