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.

An Interactive Mobile Phone-Website Platform to Facilitate Real-Time Management of Medication in Chronically ill Patients.

Poor adherence to medication is a prevalent issue that affects 50-60% of chronically ill patients. We present Medplan, a platform for patients/caregivers and healthcare professionals (HCPs) that aims to enhance adherence, increase patient medication knowledge, and facilitate communication between patients and HCPs. The Medplan platform was designed and developed by a multidisciplinary team composed of primary care and hospital physicians, pharmacists, patients, and developers. We questioned 62 patients in order to know their opinion about the different functions the app would incorporate and other possible features that should be taken into consideration. Medplan comprises a website for HCPs and an application (app) that is installed on the patient's phone. The app is available in Spanish, Catalan, and English. The patient's medication plan was introduced by the HCP and interfaced with the app. Each medicine is represented by an icon showing the indication of the treatment, the trade name, active ingredients, dose, and route of administration. Information about special requirements (e.g., need to take medication on an empty stomach), side effects, or lifestyle recommendations can also be provided. Additional functions include a medication reminder alarm system, by which patients can confirm whether or not they have taken the drug. Patients can self-track their adherence, and all data collected are sent automatically to the website for analysis by the HCP. Weekly motivation messages are sent to encourage adherence. A tool enabling interactive communication between patients and HCPs (primary care or hospital care) is also included. The app contains a feature enabling the HCP to verify the suitability of over-the-counter drugs. Medplan has the potential to significantly improve management of medication in chronically ill patients. A pilot study is being conducted to test whether Medplan is useful and effective.

mHealth intervention to improve medication management in chronically ill patients: analysis of the recruitment process.

OBJECTIVES: Mobile phones have been rapidly adopted by the general population and are now a promising technology with considerable potential in health care. However, refusal rates of 24%-75% have been reported in telemedicine studies. We aimed to report the challenges faced when recruiting patients to use Android and iOS smartphone applications aimed at improving medication management and communication between patients and healthcare professionals. METHODS: The patients invited to participate had heart failure and/or hypertension and/or dyslipidemia. After reaching the number of participants required for inclusion, the recruitment process was analyzed, and the study team determined the reasons for refusal. RESULTS: Of the 448 potential participants who were invited to participate, 210 responded. Of these, 37.1% did not use a smartphone, 2.9% owned a mobile phone that was neither iOS nor Android, and 28.6% were smartphone users who refused to participate. In this case, the most common motive was that patients considered their routine healthcare sufficient and had no trouble remembering to take their medicines (81.7%). The final study sample comprised 48 patients. The mean age of the patients enrolled was significantly lower than that of participants who were not included (59.9 ± 10.6 vs. 66.8 ± 11.4 years, respectively; p=0.00). CONCLUSION: We found age to be an important barrier to smartphone use in healthcare. Among smartphone users, good adherence and sufficient routine healthcare were the most common reasons for refusal to participate. Thus, this type of intervention could enhance participation for poor adherers or caregivers. Implementing educational initiatives could play a key role in improving patient perceptions of technology.

Feasibility and Preliminary Outcomes of a Web and Smartphone-Based Medication Self-Management Platform for Chronically Ill Patients.

OBJECTIVE: The aim of this study was to assess the feasibility and preliminary outcomes of a medication self-management platform for chronically ill patients, Medplan. METHODS: We performed a 6-month single-arm prospective pre-post intervention study of patients receiving treatment for hypertension and/or dyslipidemia and/or heart failure and/or human immunodeficiency virus infection. During the pre-intervention phase, participants were followed according to their usual care; during the intervention phase, they used Medplan. We evaluated adherence, health outcomes, healthcare resources and measured the satisfaction of patients and health care professionals. RESULTS: The study population comprised 42 patients. No differences were found in adherence to medication measured by proportion of days covered with medication (PDC). However, when adherence was measured using the SMAQ, the percentage of adherent patients improved during the intervention phase (p < 0.05), and the number of days with missed doses decreased (p < 0.05). Adherence measured using the Medplan app showed poor concordance with PDC. No differences were found in health outcomes or in the use of health care resources during the study period. The mean satisfaction score for Medplan was 7.2 ± 2.7 out of 10 among patients and 7.3 ± 1.7 among health care professionals. In fact, 71.4 % of participants said they would recommend the app to a friend, and 88.1 % wanted to continue using it. CONCLUSION: The Medplan platform proved to be feasible and was well accepted by its users. However, its impact on adherence differed depending on the assessment method. The lack of effect on PDC is mainly because patients were already good adherers at baseline. The study enabled us to validate the platform in real patients using many different mobile devices and to identify potential barriers to scaling up the platform.

Dosing of chemotherapy in obese and cachectic patients: results of a national survey.

BACKGROUND: It is not unusual to find obese and cachectic patients in the hematology oncology setting. However, information on dosage in these groups is scarce. OBJECTIVE: The objectives of our study were to explore the dosing strategies applied in the treatment of obese and cachectic cancer patients and to determine whether these strategies are applied in clinical trials. SETTING: Members of the Spanish Group for the Development of Hematology-Oncology Pharmacy (GEDEFO). METHODS: We invited all cancer hospital pharmacists to participate in a survey. MAIN OUTCOME MEASURE: Descriptive statistics of the dosing strategies approaches. RESULTS: We invited 159 eligible hospitals to participate, and 38 responded to the survey. A total of 50 surveys were received: different strategies were applied by different physicians from the same hospital and by hematology and oncology departments. Body mass index was used to define obesity and cachexia in 40 and 30 % of the cases, respectively. Capping the body surface area (BSA) was the approach most commonly followed (64.1 %) in obese patients, whereas no specific approach was adopted in cachectic patients. In hematology patients, the BSA calculation was based on ideal body weight or adjusted body weight in 16.0 % of cases (n = 2) and 50.0 % of cases (n = 6), respectively; in oncology patients, use of adjusted or ideal body weight was negligible. Actual body weight was the main approach in obese patients (35 surveys) and cachectic patients (48 surveys). Creatinine clearance was assessed mainly using the Cockcroft and Gault equation (around 76.0 % of responses). As for clinical trials, 64.1 % of the respondents (n = 25 hospitals) considered the criteria from each clinical trial individually. CONCLUSIONS: Dose adjustments are more frequent in obese patients than in cachectic patients. In cancer oncology patients, dose is adjusted mainly by hematology and hematopoietic cell transplant teams. Capping BSA is the most frequent strategy, followed by calculating actual body weight.

Neumonitis intersticial como reacción adversa a inhibidores de mTOR / Interstitial pneumonitis as an adverse reaction to mTOR inhibitors

Introducción: Los inhibidores de mTOR (del inglés mammalian target of rapamycin), sirolimus y everolimus, utilizados como tratamiento inmunosupresor en el trasplante de órganos sólidos, pueden producir efectos adversos graves, como la neumonitis intersticial. Incidencia y presentación clínica: La incidencia de neumonitis intersticial se ha estimado entre el 4 % y el 11 %, aunque podría ser mayor. La mayoría de los casos publicados se ha producido en pacientes trasplantados renales en tratamiento con sirolimus. La presentación clínica es heterogénea, lo que dificulta el diagnóstico. Se acostumbra a observar alteraciones en la tomografía axial computarizada torácica, como opacidades en vidrio deslustrado. La fisiopatología es poco conocida. Sin embargo, se ha observado una mayor incidencia en pacientes con función renal alterada y en pacientes que habían recibido inhibidores de calcineurina previamente. La relación entre aparición de neumonitis y concentraciones plasmáticas de inhibidores de mTOR no está bien definida. Tratamiento: La suspensión del fármaco y la administración de dosis altas de corticoides parecen ser efectivos. Otras alternativas terapéuticas, aunque más discutidas, son la reducción de la dosis del inhibidor de mTOR y el cambio de sirolimus a everolimus. Conclusión: Se debe sospechar de neumonitis iatrogénica en pacientes trasplantados en tratamiento con inhibidores de mTOR y con síntomas respiratorios. Faltan datos concluyentes en cuanto a estrategias de tratamiento. Parece que everolimus podría ser mejor tolerado que sirolimus (AU)

Introduction: mTOR (mammalian target of rapamycin) inhibitors sirolimus and everolimus, used as immunosuppressants in solid organ transplantation, may cause severe adverse effects, such as interstitial pneumonitis. Incidence and clinical presentation: The estimated incidence of interstitial pneumonitis is 4-11% although it may be higher. Most reported cases have occurred in renal transplant recipients treated with sirolimus. Clinical presentation is heterogeneous, which makes diagnosis difficult. Abnormalities, such as ground glass opacities, are often found in computerised axial tomography scans of the chest. Physiopathology is not well-known. However, patients with abnormal renal function and those with previous calcineurin inhibitor treatment display a higher incidence. The relationship between pneumonitis and mTOR inhibitor plasma concentrations is not well defined. Treatment: Drug discontinuation and administration of high doses of corticosteroids seems to be an effective treatment. mTOR inhibitor dose reduction and replacing sirolimus with everolimus are other alternatives, but they are still under discussion. Conclusion: Iatrogenic pneumonitis must be suspected when a transplant recipient being treated with mTOR inhibitors presents respiratory symptoms. There is lack of conclusive data on treatment strategies. It appears that everolimus may be tolerated better than sirolimus (AU)

Prescribing of zoledronic acid in a tertiary outpatient hospital setting.

BACKGROUND: Zoledronic acid (ZA) is an intravenous bisphosphonate approved for the prevention and treatment of cancer skeletal-related events. OBJECTIVE: Our aim was to analyze the prescription patterns of ZA in the cancer outpatient clinic. METHOD: We performed a retrospective chart review of all patients who received at least 1 dose of ZA from January 2009 until December 2010 in our institution. The patients' follow-up period was defined from the administration of the first dose until February 2011. RESULTS: The sample comprised 345 patients: 31.9 % had breast cancer, 14.5 % prostate cancer, 29.0 % multiple myeloma, and 24.6 % other solid tumors. A total of 4,546 doses were administered; 2,749 (60.5 %) without intravenous chemotherapy. 71.1 % of patients with breast cancer, 86 % with prostate cancer, 60 % with multiple myeloma and 44.6 % with other solid tumors, received ZA without intravenous chemotherapy throughout bisphosphonate treatment. Doses were adjusted in one-third of cases. Administration every 4-weeks was the most frequent schedule. Median duration of treatment varied between 15.0 months for breast cancer and 4.2 months for other solid tumors. CONCLUSION: Most of ZA prescriptions in cancer outpatients followed the labeled indications. The percentage of ZA doses administered without intravenous chemotherapy was 60.5 %.
