Home Monitoring of Complete Blood Count Performed by Patients - a Pilot Study on the Implementation Process in South Baltic Countries.

Overview

Introduction: The number of diagnosed cancers is systematically increasing every year. Cancer patients need to undergo regular blood tests to monitor safety and eligibility for treatment. In case of poor blood results, the chemotherapy session must be omitted. For patients living far from the center, this means unnecessary travel with involvement of helpers, additional costs, increased potential of hospital acquired infections, and frustration associated with missed opportunity for treatment. Aims: The primary aim of this study is to gain knowledge about successful implementation of remote, home monitoring of complete blood count to cancer patients during and after systemic treatment for cancer. The secondary aim of the AMBeR collective study protocol is to pilot new technology, gain more context around future investigations and verify costs and changes in patient treatment pathways. Methodology: The investigators will test implementation of home blood monitoring in three South Baltic Countries (DK, PL, GER). Each site will participate in the implementation study with study group á n=33 (total n=165) and control group n=20 (total n=100). The duration of the study is planned for 4 cycles of chemotherapy for each patient and a 3-month follow up period. The first cycle of learning and training at the Outpatient Daily Clinic, then the remaining 3 cycles of blood monitoring at home. The average cycle length is 21-30 days, number of measurements will be determined individually depending on the diagnosis. At a baseline, after 4 cycles of chemotherapy (12-16 weeks) and after a 3-month follow-up period, parallel studies will be carried out in both the study and control groups, using mixed methods the investigators will assess outcomes of reach, effectiveness, adoption, implementation and maintenance (RE-AIM). Expected benefits: Implementation of the AMBeR study should reduce the amount of unnecessary and nontherapeutic hospital visits and improve manageability and independence of the patients. The investigators believe that the decrease in the number of hospital visits will diminish the risk of infection for vulnerable individuals, as well as save costs for patients and hospitals. These factors will also translate into better logistics of chemotherapy units, decreased carbon-dioxide trail, and improved quality of life and patient empowerment.

Introduction: The incidence of cancer is expected to increase by 30% over the next 20 years, mainly due to the increase in the elderly population. This will lead to a dramatic increase in the number of cancer patients in the future. Cancer patients need to undergo regular blood tests to monitor safety and eligibility for treatment. In case of poor blood results, the chemotherapy session must be omitted or modified. For patients living far from the center, this means unnecessary travel with involvement of helpers, additional costs, increased potential of hospital acquired infections, and frustration associated with missed opportunity for treatment. Digitizing cancer care can increase patients' active involvement in their own treatment, improve quality of life and reduce inequalities in access to health care. Therefore, there is a strong need to develop and implement new ways of making cancer diagnostics and treatments available to patients in their own homes. Objective The primary aim of this study is to gain knowledge about successful implementation of remote, home monitoring of complete blood count to cancer patients during systemic treatment for cancer. The secondary aim of the AMBeR collective study protocol is to pilot new technology, gain more context around future investigations and verify costs and changes in patient treatment pathways. Methods Trial design This study is a multinational multisite implementation research study to pilot test implementation of home blood monitoring in 3 South Baltic countries (PL, DK, GER). Study setting and organization The current study is part of the Interreg South Baltic Program-funded project "AMBeR" (Advanced Modelling of Baltic cancer e-caRe). A total of seven partners from five countries are involved and are working on five different WP's. The following 5 of the 7 project partners are involved in the study (WP3): 1) Zealand University Hospital Næstved, Denmark (ZUH); 2) University Medical Center Rostock, Germany (UMC Rostock); 3) University Medical Center Greifswald, Germany (UMC Greifswald); 4) University Clinical Center Gdańsk, Poland (UCC Gdańsk); 5) Pomeranian Medical University Szczecin, Poland (PMU). Intervention The aim of this study is to evaluate the feasibility and validity of home monitoring of blood parameters during systemic treatment of cancer patients using the HemoScreen device in the patient's home. Participants will be oncology patients undergoing outpatient chemotherapy in Oncology and Hematology Departments in 5 different centers in the South Baltic region. The investigators plan to enroll 33 patients from each center in the study group and 20 patients in the control group. Patients in the control group will undergo standard chemotherapy treatment and blood monitoring in general laboratory at the Outpatient Daily Clinic. Patients from the study group will be instructed in the use of the HemoScreen device by trained staff and will complete self-tests throughout their first cycle of chemotherapy at the Outpatient Daily Clinic (average cycle duration 21-30 days, number of measurements determined individually depending on the diagnosis). Patients will then be given HemoScreen to use at home and will be tested immediately or up to 48 hours before their scheduled outpatient visit for chemotherapy. The results obtained will be sent to the coordinator via the IT system at least 24 hours before the planned administration of chemotherapy to determine contraindications to treatment. If the results do not qualify for chemotherapy, depending on the center, a decision will be made to arrive to the Outpatient Daily Clinic to verify the test or to postpone the visit and issue recommendations. Each time a patient arrives at the Outpatient Day Clinic for chemotherapy, a standard venous blood test will be performed in the general laboratory. Any decision on the final administration of chemotherapy will be based on the blood count obtained from the general laboratory, not from the HemoScreen device. All trial procedures are done in addition to standard care. The duration of the study was planned for 4 cycles of chemotherapy for each patient and a 3-month follow-up period. The first cycle of learning and training at the Outpatient Daily Clinic, then the remaining 3 cycles of blood monitoring at home. At a baseline, after 4 cycles of chemotherapy (12-16 weeks) and after a 3-month follow-up period, parallel studies will be carried out in both the study and control groups, using questionnaires (PROM's) assessing a health status and quality of life to evaluate the impact of an intervention. Implementation * describing the existing care process and identifying stakeholders. * describing new care process, stakeholders and pathways in the new practice. * Workshop 1:" setting the scene" context mapping, barriers and facilitators, solution design, action plan. Participation from all relevant stakeholders identified through context mapping of the care process. A patient representative will be involved and engaged in workshop if possible, and thereby contribute with the patient perspective on barriers and facilitators. * Education and preparing health care professionals (HCP's) to use of the digital technology and integrating it into the "toolbox" and new professional identity. * Workshop 2 "facilitating/supporting the ongoing process" mid-pilot, dealing with challenges, adjusting design, planning, and supporting further implementation. * Workshop 3 "selecting the fruits of best practice" post-pilot, including examining learnings from the pilot trials and evaluating finalized, ongoing and planned implementation. * A logbook describing the process, actions, and rationale for all steps of the implementation will be used for documentation throughout the intervention phase. Following workshop 1, pre-study identification of expected barriers and facilitators for patients to engage in remote blood monitoring at home will be carried out in 4 steps: * Summary from literature review and past experiences. * Matching the most important barriers with strategies using the ERIC matching tool. * Ranking strategies by effectiveness and importance in each center's clinical setting. * Building on strategies to develop action plans to implement interventions in each site. Assessing RQ1: Patient's and HCP's perspectives on determinants In the final phase of the pilot study, the investigators will examine the perspectives of patients and HCPs on important determinants of engagement in remote home blood monitoring using the Group Concept Mapping technique. The process will follow 5 pre-described steps and all activity will be online utilizing the software Groupwisdom: 1. Brainstorming 2. Sorting and labelling 3. Rating 4. Generating a cluster rating map 5. Validation of the cluster rating map Quantitative outcomes The investigators will use the RE-AIM framework (REF) for a systematic quantification of outcomes. A range of different outcomes, measurement methods and data sources will be used. Data collection and management A REDCap database will be created for all study outcomes and relevant data to be collected and safely stored. Participant and Non-participant questionnaires To obtain information about eligible patients who refuse participation in remote home blood monitoring, the investigators will invite patients to complete a short survey containing information about their characteristics, reasons for refusal, and barriers to participation. Patients who accept participation will receive a larger questionnaire reporting further on Patient Reported Outcome Measures (PROMs) and Patient Reported Experience Measures (PREMs). PROMs and PREMs will be collected using validated questionnaires. Additionally, the investigators want to examine the implementation process. To this end, a survey will be conducted at the end of the study to examine participants' and medical professionals' experiences of implementation. Effectiveness evaluation At the baseline, after 16 weeks of treatment and 3 months of follow-up, a survey will be conducted regarding patients' perceptions of their care experience, including quality of life (PROM's - EORTC QLQ C30; EQ-5D 5L) and acceptability (Theoretical framework of Acceptability). Adherence to home blood testing and adverse events will be recorded throughout the study. At the same time, the investigators will analyze the number of unnecessary and non-therapeutic hospital visits that could potentially be avoided. Finally, health economic data will be collected to assess the economic value of the project and conduct cost-benefit analysis. Harms and drop-outs Remote blood monitoring may be associated with adverse events and the ongoing and systematic registration of harm, drop-out and reasons for drop-out. This information will be recorded in the database on a day-to-day basis. Economic/resource evaluation Based on the collected process data, the investigators will conduct an economic analysis assessing the time, resources and costs used for remote home monitoring. Additionally, the investigators would like to evaluate the price of the device with disposable materials, maintenance costs, time and amount of money necessary for training. Thanks to the above calculations, the investigators will try to estimate the cost-effectiveness of the change and the effective use of resources to perform blood test at home. Sample size in pilot trials First, sample size of the pilot trial was estimated based on considerations to ensure sufficient accumulation of experience at each site to draw upon in the development of eMOC, supported by the literature on sample size recommendations for pilot and feasibility trials. Second, the investigators defined success in the study if patients were able to use the HemoScreen equipment properly at home by following the instructions they received. Failure was defined as when the patients must call the helpline or notice that they are not using the equipment correctly at home. The investigators assumed the expected probability of success at po = 0.90. The investigators decided that if the probability of success is p=0.70 (or less), then the HemoScreen may not be useful in a given context. The null hypothesis of the study is Ho: p = p0, and the investigators wanted to test the alternative hypothesis Ha: p \<p0 (one-tailed test) with a probability of 5% or less and a power of 80%. The estimated necessary sample size is N = 33 patients. By consortium decision, each pilot study included 33 participants at each site, resulting in a total pooled sample of 165 participating patients. The consortium decided to enroll 20 control patients from each site, resulting in a total sample of 100 participants. Therefore, a total of 265 patients were planned to participate in the entire study. Statistical methods Mainly descriptive statistics will be used to analyze quantitative outcomes, although effectiveness will be assessed with a pre-post change score. Ethics approval and consent to participate An application for ethics approval will be submitted in each participating country, with local adaptations of this protocol.
