Abstract
Background
The acceptability and impact of mobile health (mHealth) applications on health outcomes in haemato-oncology remain unclear, particularly for patients undergoing long-term oral systematic anticancer therapy (SACT).
Purpose
This systematic review investigated the acceptability and efficacy of mHealth applications in facilitating self-management of oral SACT in patients with haematological malignancies.
Methods
We conducted a comprehensive search of five electronic databases, PubMed, PsycINFO, CINAHL, Cochrane Library, and Web of Science, until October 2024, and extracted data, including methodologies, application names, functionalities, and key results. This was followed by a narrative synthesis of quantitative outcomes, and a thematic analysis of qualitative data.
Results
Eight studies were included, comprising three qualitative studies, one randomised controlled trial, one non-randomised trial, and three mixed-method studies. mHealth applications for self-managing oral SACT exhibited acceptability, with usability and satisfaction ratings between 60% and 78%. Using the Normalisation Process Theory, four themes influencing acceptability were: (1) coherence – perceived benefits, (2) cognitive participation – barriers from technical issues, (3) collective action – burden from excessive notifications and inadequate support, and (4) reflexive monitoring – integration challenges in daily routine. Despite no major clinical or behavioural improvements, mHealth applications enhanced patient awareness of support, online health knowledge, and reduced daily life impact.
Conclusion
Fostering effective self-management of oral SACT in patients with haematological malignancies requires addressing issues such as application glitches, notification fatigue, and integration barriers to optimise these interventions. Future well-designed clinical trials are warranted to validate the impact of these applications on patient outcomes in cancer care.

Introduction
Oral systemic anticancer therapy (SACT) has revolutionised the treatment landscape for certain haematological malignancies, facilitating a transition towards a chronic disease model and enabling prolonged survival rather than a terminal prognosis. Haematological malignancies encompass a diverse group of cancers that primarily target the blood, bone marrow, and lymphoid tissues. This category includes significant types, such as leukaemia, lymphoma, and myeloma, which collectively account for 6.5% of the estimated 20 million new cancer cases and 7.1% of cancer-related mortalities reported in 2022. 1
Despite their classification as incurable diseases, many indolent blood cancers have demonstrated improved prognoses, mainly driven by advancements in molecularly targeted therapies. The rising global incidence of cancer, which accelerated from approximately 18 million in 2020 2 to 22 million in 2022, 1 presents significant public health concern and warrants effective strategies to meet the complex needs of patients treated on oral SACT living in the community, especially in the setting of haematological malignancies where surgical resection is not a treatment option.
However, a fundamental challenge persists in ensuring patient adherence to prescribed treatment regimens. A study conducted in the Netherlands revealed an alarming 50% adherence rate among patients with haematological cancers, including conditions such as acute leukaemia, chronic leukaemia, non-Hodgkin lymphoma, and multiple myeloma. 3 Suboptimal adherence to oral SACT can lead to serious therapeutic complications, such as the emergence of resistance to tyrosine kinase inhibitors (TKIs) in chronic myeloid leukaemia (CML), due to oscillations in drug concentration within cancer cells. 4 Moreover, suboptimal adherence complicates patient management, leading to increased healthcare costs associated with switching therapies, increased hospitalisation for procedures such as stem cell transplantations, poor prognoses, higher relapse rates, and decreased overall survival.3,5–7 Notably, significant differences in major molecular response (MMR) and event-free survival (EFS) rates were observed among CML patients based on their adherence levels. 8
Several factors contributing to non-adherence to oral SACT have been identified in various studies. A scoping review highlighted three primary barriers: side effects and toxicity, forgetfulness, and limited access to reliable information. 9 Forgetfulness has been consistently implicated in reduced medication adherence among patients with leukaemia.10–12 Furthermore, a systematic review concerning multiple myeloma patients found that up to 36% reported discontinuing treatment, frequently owing to adverse effects such as haematologic and gastrointestinal toxicity. 13
The autonomy associated with home-based oral SACT administration often leads to diminished oversight and monitoring from healthcare providers, contrasting with the well-established protocols for intravenous chemotherapy. Patients with haematological malignancies often experience unique clinical challenges such as prolonged treatment, require frequent monitoring, and a high symptom burden across different phases of the disease. These distinct clinical characteristics may necessitate tailored solutions that differ from those developed for solid tumour cancer populations.
mHealth or mobile health, as outlined by WHO's Global Observatory for eHealth, refers to “Medical and public health practices supported by mobile devices, such as mobile phones, patient monitoring devices, personal digital assistants (PDAs) and other wireless devices”. 14 The COVID-19 pandemic has accelerated the integration of mHealth applications into the contemporary healthcare system. These applications promote self-management by providing actionable feedback that can mitigate adverse effects and enhance patients’ quality of life.15,16 Medication self-management, as described by Bailey et al., includes taking medications as prescribed while considering aspects such as dosage, frequency, and long-term safety. 17 In the context of oral SACT, self-management entails health surveillance, recognising changes in health status, seeking assistance, and autonomously managing side effects. 18
Understanding patient acceptance and engagement with mHealth applications is essential to developing practical tools that align with the self-management needs of patients undergoing oral SACT. A systematic review by Gutierrez et al. assessed available mobile applications designed for patients with haematological malignancies, uncovering a disappointing average quality score of merely 3.1 out of 5, with particularly low ratings for engagement and aesthetics. 19 Moreover, Chow et al. carried out a review and meta-analysis revealing that while mHealth applications effectively managed side effects related to oral SACT compared to usual care, their influence on adherence was not statistically significant. 20 Eminently, only a small percentage (7.1%) of patients included in this analysis had haematological malignancies, underscoring the necessity for more tailored investigations. Furthermore, user experience studies indicated that many cancer-focused mHealth applications were developed with insufficient input from patients, showcasing a gap in understanding user preferences regarding the application. 21
According to Hinrichs-Krapels and Grant,
Therefore, this study aims to systematically assess the acceptability of mHealth apps designed to support the self-management of oral SACT in patients with haematological malignancies and to evaluate the efficacy of these apps in achieving intended clinical and patient-reported outcomes. Addressing the challenges of adherence to oral SACT through innovative, technology-driven solutions represents a promising avenue for enhancing the quality of care offered to patients grappling with these conditions. By exploring these dimensions, this research seeks to contribute to the development of effective self-management practices within the context of oral SACT.
Methods
This review was conducted to answer the research question: "Are mHealth applications designed to support oral SACT self-management practice for patients with haematological malignancies acceptable and efficacious?" The reporting of this systematic review adhered to the synthesis without meta-analysis (SWiM) guideline 28 and the preferred reporting items for systematic reviews and meta-analyses (PRISMA) as in Appendix 1. 29 The protocol for this review was registered with PROSPERO (ID: CRD42024583595) in October 2024.
Eligibility criteria
Fully published original research that evaluated the acceptability and efficacy of mHealth applications developed to aid self-management of oral SACT in patients with haematological malignancies was included in this review (Table 1). Eligible study designs included quantitative (survey, pilot study, trial), qualitative (focus group, interview) and mixed-methods research published in English-language peer-reviewed journals. The outcomes focused on mHealth applications’ acceptability or efficacy on medication self-management skills (self-efficacy, knowledge, medication adherence) and clinical outcomes (symptom, health-related quality of life) reported by patients or healthcare providers.
Inclusion and exclusion criteria of systematic review.
Studies were excluded if they (1) involved patients with haematological malignancies exclusively receiving parenteral SACT, undergoing stem cell or bone marrow transplants in an inpatient setting, or included mixed cancer population; (2) assessed mHealth solutions other than smartphone applications such as text messaging; or (3) failed to report outcomes on the acceptability or application efficacy in supporting medication self-management practices from the patient and/or healthcare provider perspective.
Search strategy
Five electronic databases, including PubMed, APA PsycINFO, CINAHL, Cochrane Library and Web of Science, were searched for relevant literature published from inception to October 2024. The search employed Medical Subject Headings (MeSH) terms and Text Word keywords aligned with the research question using the Population Intervention Comparison Outcome framework (Appendix 2). Keywords included ‘haematological malignancies’, ‘mobile applications’, ‘self-management’, ‘adherence’ and ‘side effects’, alongside relevant synonyms. Search terms were combined using ‘OR’ and ‘AND’ Boolean operators to develop robust search strategies. Initial pilot testing of search strategies was conducted in PubMed by LM, with results subsequently discussed with BKT and LCC before replication across other databases.
Selection of studies
Search results retrieved from the five databases were imported into Zotero citations management software (version 6.0.37) for removal of duplicates, then uploaded to Rayyan.ai, a systematic review tool, for title and abstract screening. Two researchers (LM and BKT) independently screened articles based on the predetermined inclusion and exclusion criteria (Table 1). Each article was classified as ‘included’, ‘excluded’, or ‘maybe’ (if the title and abstract lacked sufficient information for a definitive decision). To assess the consistency of ratings between the two reviewers (LM and BKT), the intraclass correlation coefficient (ICC) and 95% confidence interval (95%CI) were calculated using SPSS (software, Chicago, IL, USA version 26). 30 ICC values indicated poor (<0.5), moderate (0.5 to 0.75), high (0.75 to 0.9) and excellent (>0.90) reliability.
The full texts of articles categorised as ‘included’ and ‘maybe’ were retrieved accordingly to undergo a more thorough evaluation. Both LM and BKT assessed these full texts against the eligibility criteria independently to determine their relevance to the study. Articles that met all inclusion criteria were confirmed for final selection, while those that did not were excluded. For any discrepancies and articles categorised as ‘maybe’, reviewers engaged in further discussion to resolve differences and reach a consensus.
Quality assessment
The methodological quality of the included studies was assessed using the Mixed Method Appraisal Tool 31 (MMAT; version 2018). Two reviewers (LM and BKT) conducted the appraisal independently. Each paper underwent an initial screening to identify eligibility. Studies receiving ‘No’ or ‘Can't tell’, responses to one or both screening questions were excluded from a detailed appraisal. The quality of each study design (qualitative, quantitative, and mixed methods studies) was assessed using the applicable 5-item quality criteria. 31 Each quality criterion was classified as ‘Yes’, ‘No’ or ‘Can't tell’ with an assigned score, 20% for ‘Yes’, and 0% for ‘No’ or ‘Can't tell’. The total score ranged from 0% to 100%, reflecting the number of criteria met. Mixed methods studies were evaluated using both the mixed methods criteria and the specific criteria for each study component.
Data extraction and analysis
Data regarding study design, author, publication year, country, sample size, cancer type, features of mHealth applications, comparators (for trials), acceptability and efficacy measures, and results were extracted by LM using a standardised form, which was then reviewed by the research team. The form was piloted on two studies to ensure it met this review's objective. The features of the included mHealth interventions were extracted and categorised using the groupings and labels specified in the behaviour change technique (BCT) Taxonomy v1, 32 a standardised guideline for identifying behaviour change components. The developmental stages of the mHealth applications were categorised based on the 6-step development and evaluation framework of mHealth interventions as proposed by Whittaker et al. 33
Given the heterogeneity of the included studies, a narrative synthesis 34 of quantitative findings and a thematic analysis 35 of qualitative findings extracted from the result sections of the included studies were conducted. Thematic analysis followed Braun and Clarke's (2006) 35 six-phase framework: (1) familiarisation with the qualitative findings from the included studies; (2) generating initial codes to systematically identify recurring factors influencing acceptability; (3) constructing themes by organising codes into conceptually meaningful categories, guided by the four domains (coherence, cognitive participation, collective action, and reflexive monitoring) of the normalisation process theory (NPT) developed by May et al., 36 which explains how new practices like mHealth become integrated into routine care; (4) reviewing themes collaboratively to ensure coherence and theoretical alignment with NPT; (5) refining and naming themes to clearly incorporate the factors influencing acceptability within the four domains of NPT; and (6) reporting themes as illustrated using a conceptual framework. Mapping to NPT provided a robust framework for interpreting how these interventions are sustained in clinical practice.
Results
Study selection
The systematic search across five databases yielded a total of 267 articles, of which 74 duplicates were removed. Following the title and abstract screening of 193 articles, 173 were deemed irrelevant or did not meet the inclusion criteria. Agreement between reviewers on study inclusion was high (ICC=0.789; 95%CI: 0.729, 0.837). Full texts for the remaining 20 articles were retrieved for eligibility assessment, leading to the exclusion of 12 additional articles, resulting in 8 articles for this review. The study selection process is illustrated in Figure 1

Characteristics of included studies and mHealth application models
The included studies comprised one randomised controlled trial (RCT; n=1), 37 one quasi-experimental design (n=1), 38 three qualitative studies (n=3),39–41 and three mixed methods studies (n=3),42–44 published between 2017 and 2024. Sample sizes varied from 10 to 108 participants: the RCT included 38 participants, the quasi-experimental study had 108, qualitative studies ranged from 11 to 47 participants, and mixed methods studies ranged from 10 to 106 participants. Geographically, three studies were conducted in the Netherlands, two in Australia, and one each in the United States, South Korea and Iran. The majority (n=5)38,40,41,43,44 focused on CML, while two studies examined a mix of two or more haematological malignancies37,42 and one specifically concentrated on acute lymphocytic leukaemia (ALL). 39 Seven studies targeted adult populations,37,38,40–44 while one was designed for paediatrics. 39 Four studies sought input on application functionalities and acceptability from both patients and healthcare providers,39–41,44 whereas the other four relied solely on patient feedback.37,38,42,43 A summary of the study characteristics is presented in Table 2.
Characteristics of the eight studies included in this review
(Note) IG: Intervention group; CG: Control group
Of the eight interventions, seven37–43 were hybrid systems combining mobile apps and web platforms, while only one 44 was solely mobile app-based. All studies reported various features of the mHealth applications. The most common feature was symptom/side effect self-monitoring (n=8),37–44 followed by symptoms monitoring by HCP (n=7),37–43 information on disease/treatment (n=7),37–40,42–44 reminder (n=6),37–39,41–43 wellness information (n=6),37–40,43,44 engagement with HCP or peers (n=6), laboratory results (n=4),38,40,42,43 symptom assessment (n=4).39,41,42,44
These intervention features were grouped and mapped to the corresponding BCT categories and codes, using the BCT Taxonomy v1. The mapping process revealed techniques spanning several key domains. Within ‘goals and planning’, features such as symptom assessment was assigned accordingly, while laboratory results, symptom tracking, and provider-led monitoring were placed under ‘feedback and monitoring’. Interaction with healthcare providers or peers was linked to ‘social support’. Content related to lifestyle or mindfulness practices fell within the ‘shaping knowledge’ category. Likewise, information about disease and treatment was coded under ‘natural consequences’, and reminders were associated with the ‘Associations’ domains. A detailed classification and summary can be found in Table 3.
Key features of applications across included studies based on BCT taxonomy v1
Based on Whittaker et al.'s mHealth intervention development and evaluation framework, this review identified one study 40 in the formative research phase, four studies (three mixed methods42–44 and one qualitative 39 ) in the pre-testing phase, two were pilot studies37,41 and only one non-randomised trial, 38 as illustrated in Table 4. Additionally, various methodological approaches were utilised across the studies, including behavioural science research, 42 participatory action research, 43 design thinking development, 40 and user-centred design 39 ; however, only two41,44 followed specific self-management frameworks, such as the middle-range theory of adaptation to chronic health conditions. 45
Summary of the mHealth applications’ developmental stages
Quality of the included studies
The eight studies included were classified by design: three qualitative, three mixed-method, one RCT, and one non-randomised trial. The quality assessment of individual studies is shown in Appendix 3.
The MMAT scores of the studies ranged from 40% (one qualitative study 39 and one mixed method study 44 ) to 100% (non-randomised trial, 38 which fulfilled all the quality criteria). Among the qualitative studies, two39,40 lacked sufficient data, coherence and transparency in the analysis process, while another 41 reported a small sample size without evidence of thematic saturation. For the quantitative studies, LeBlanc et al. 37 did not detail random number generation or allocation concealment. Also, participant retention was low, with 53% and 39% completing surveys in weeks 4 and 8. Among the mixed-method studies, two42,43 fully met qualitative criteria but scored 60–80% in the quantitative criteria due to sampling limitations and the use of unvalidated questionnaires. Finally, Song et al. 44 scored the lowest, providing minimal, non-integrative results from a small sample despite meeting qualitative (80%) and quantitative (60%) criteria.
Acceptability towards the applications and influencing factors
mHealth applications for self-managing oral SACT were generally acceptable to patients with haematological malignancies, with usability/satisfaction ratings between 60% and 78%. In this study, acceptability of mHealth applications refers to users’ perceptions assessed through relevant validated scales or TAM focusing on domains such as usefulness, usability, satisfaction, and feasibility. LeBlanc et al. 37 defined the acceptability of the Blood Cancer Coach application based on perceived helpfulness and satisfaction, considering the application acceptable if over 70% of participants rated their satisfaction as moderate or higher (Likert score ≥ 3) and they found 73% of participants reported overall satisfaction with the Blood Cancer Coach application.
In contrast, Dang et al. 42 utilised the Evaluation Tool for Mobile and Web-based eHealth Interventions (Enlight) to assess the SAMSON application based on six quality constructs, including usability. Among 27 participants, 21 (78%) of SAMSON users rated it easy to use. On the other hand, Verweij et al. 43 applied the System Usability Scale (SUS) to evaluate the usability of the CMyLife application, scoring it 65.3 on the guideline and 60 on the medication platform. A SUS score <51 indicates poor usability, 51–68 indicates acceptable usability, 68–80.3 indicates good usability, and 80.3–100 indicates excellent usability. Furthermore, 64% (n=39) of the CMyLife application users reported daily usage, indicating practical usability.
Qualitative data extracted from six studies (three mixed-method and three qualitative) uncovered four themes influencing applications’ acceptability. The acceptability influencing factors of mHealth applications in this review are illustrated in Figure 2 and mapped to the constructs of NPT.
Themes of mHealth application acceptability factors and efficacy. Coherence – beneficial features that add value Coherence in NPT refers to users’ ability to comprehend the purpose of the intervention and assess its benefits.
46
The first theme centres on application features that add value; the reminder function was the most common for enhancing medication adherence and accountability. Monitoring and self-managing symptom distress were pivotal in the SAMSON application
42
and the REMIND system.
41
Both the CMyLife application
40
and the REMIND system
41
incorporated healthcare professional engagement, offering screen-to-screen and nurse-assisted consultations, respectively, which were well-received. Haematologists noted the empowering potential of CMyLife
40
in transferring care outside the hospital, while nurses highlighted its utility in addressing adherence issues.
36
Cognitive Participation – technical glitches and suboptimal user interfaces Cognitive participation involves users’ willingness to commit to and actively engage with the intervention
46
; however, technical glitches and suboptimal user interfaces can obstruct this, forming the second theme. SAMSON application
42
users reported frustrations due to long loading times and navigation difficulties, particularly among older adults with limited technological proficiency. Pereira-Salgado et al.
41
noted that users with unstable network connections faced delays in receiving medication reminders. Users of the CanSelfMan,
39
SAMSON,
42
and CMyLife
43
suggested enhancing clarity, primarily through visuals and simplified language. Limitations in functionality were reported, as well as difficulties in editing lists and reminders. Participants using the CanSelfMan,
39
aimed at children, recommended adding engaging elements like cartoon characters and improving the visual representation of symptom evaluation. Collective Action – excessive notifications, insufficient support and updates Collective action, the third construct of NPT, describes the coordinated efforts and support of all stakeholders to ensure the functionality of the intervention.
46
Given this context, the third theme emerges, highlighting excessive notifications, inadequate support and inconsistent content updates. Users of ReLive,
44
REMIND,
41
and CMyLife
43
reported frustrations due to frequent notifications, including relentless symptom logging and adherence reminders. Concerns arose in Verweij et al.'s CMyLife study
43
regarding content updates, whereas ReLive
44
users noted insufficient guidance post-symptom scoring. Reflexive Monitoring – challenges integrating into daily routine Reflexive monitoring focuses on the implementation of the intervention and provides feedback for continuous improvement.
46
The fourth theme discusses challenges in integrating the applications into daily routines. Haematologists in the CMyLife study
40
expressed difficulty in integrating the application with hospital electronic health systems and the time commitment required for patient-provider interactions. Similarly, a nurse from the REMIND
41
study mentioned the need for more time to adapt to the system. Furthermore, users highlighted the need for CMyLife
40
to address comorbidities rather than functioning as a standalone application. Some ReLive
44
users rated the application poorly due to perceived disruption, with newly diagnosed patients expressing a greater inclination to engage compared to those with long-term, stable conditions.
37

Efficacy of applications
Two studies assessing mHealth applications’ efficacy showed no major clinical or behaviour improvement, though some impacts on awareness of additional help outside hospital, online health knowledge, symptom burden and impact on daily life were noted. LeBlanc et al. 37 evaluated the efficacy of Blood Cancer Coach on clinical and behavioural outcomes, measuring patient-reported outcomes at baseline, 4 weeks, and 8 weeks. However, no significant differences were observed between the control (n=22) and intervention (n=16) groups in global health, posttraumatic stress, or cancer symptom measures. 37
In Verweij's study, improvements in the intervention group were observed in aspects such as “additional help outside the hospital” and online health information. However, no significant differences were found in other eHealth literacy parameters, patient activation measure, and medication adherence. 38 Notably, EORTC-QLQ-CML24 health-related quality of life scores indicated a reduction in the impact on daily life, though patients reported heightened symptom burden, as evidenced by significant statistical changes. 38 The results of the mHealth application acceptability factors and efficacy in supporting self-management practice of oral SACT are summarised in Figure 2.
Discussion
Principle findings
This review investigated the acceptability and efficacy of mHealth applications among patients with haematological malignancies undergoing oral SACT. Participants in six studies investigating acceptability reported overall positive feedback regarding usability and satisfaction. This aligns with Technology Acceptance Model 47 which posits that acceptability is driven by perceived ease of use and perceived usefulness, both of which significantly influence technology adoption. Although there were no major changes in clinical or behavioural outcomes in the two remaining studies, the CMyLife application successfully increased patients’ knowledge of online health information, consistent with studies by Potdar et al. and Ashruf et al.48,49 It also offered additional help outside the hospital, indicating a positive impact on quality of life through heightened symptom awareness and management.
This review underscored four key factors influencing application acceptability based on the four constructs of NPT, 36 which are coherence, cognitive participation, collective action, and reflexive monitoring. Within coherence, features such as reminders, symptom tracking, educational resources, and communication with healthcare providers were perceived as valuable for patients and experts in supporting self-management beyond clinical settings. The same result is evident in Leidong et al.'s study where mobile applications for cancer management successfully supported adherence through behavioural changes, symptom management, healthcare professionals interaction, and improved quality of life. 50
For cognitive participation, technical difficulties and suboptimal interfaces may hinder user acceptability, discouraging them from investing time and energy into the application. To combat this, application developers must prioritise a seamless, user-friendly experience that facilitates intuitive navigation. According to Langote et al., optimal healthcare interface can be achieved through user-centred design approach, visibility, learnability, flexibility, and error prevention, among others. 51
In terms of collective actions, excessive notifications may overwhelm users, while inadequate support and inconsistent content updates generate dissatisfaction, which impedes further participation. Under reflexive monitoring, users struggled to integrate the application into their daily routine, constantly evaluating if it met their needs. This resonates with findings by Han et al., Cao et al. and Yadav et al. whereby if the expected benefits do not outweigh the effort required, sustained usage is uncertain.52–54 This entire process ultimately dictates whether the application can become a routine part of self-management practices. 46
Results of our review showed that a common barrier to implementation of the applications is the added workload on clinical staff which is in agreement with findings by Ardito et al. and Richards et al.55,56 This often includes extra effort and time commitment required from doctors or other healthcare providers to oversee the application.57–59 Our review also revealed that the involvement of healthcare providers in application development was overlooked in some studies. This echoes findings of a review of 123 cancer applications where only 3% (4 out of 123) involve participation of healthcare providers in their development and assessment. 60 The absence of expert contribution can lead to the uncertainty of content verification.61–64 Hence, collaborating with healthcare professionals during the application development process is essential for ensuring the accuracy of medical content and the inclusion of user-centred design elements that add value to patient care without increasing the burden on providers.
The advent of mHealth applications represents a transformative step in healthcare delivery, significantly improving access to health services and allowing users to manage their conditions proactively. However, the successful integration of mobile applications 65 into healthcare heavily relies on the quality of real-time data exchange between patients and healthcare professionals. To truly meet the needs of users, their feedback must be included at all stages of application development. In this review, seven included studies employed patient-centric approaches,66–69 yet widespread barriers, such as lack of technical support, persist and hinder adoption.
In contrast to the findings of Wu et al., who reported several cancer pain self-management applications improved health outcomes - such as medication adherence and symptom control - this review suggests the gaps present in the current landscape of mHealth for haematological malignancies. 70 Future applications should incorporate features like colour-coded alerts for toxicity severity, self-care instructions, and tracking for condition-specific metrics, such as sleep, 71 to enhance user acceptability and adherence.
This systematic review also highlighted the limited availability of mHealth applications specifically tailored for patients with haematological malignancies, particularly for acute myeloid leukaemia (AML). With the rising incidence of AML, especially among aging populations and an increase in newly approved oral SACT such as venetoclax and midostaurin since 2017, 72 there is a crucial need for resources to support this demographic. Current mHealth solutions primarily address patients with solid tumours, particularly breast cancer, thereby underscoring the pressing need for innovations targeted at patients with chronic conditions like haematological malignancies. 73 Additionally, we found a notable absence of studies conducted in low-income countries, where Short Message Service (SMS) solutions are more common than application-based solutions.
Whittaker et al. emphasised the importance of involving both patients and experts throughout the development of mHealth interventions, recommending a six-step process: conceptualisation, formative research, pre-tests, pilot studies, RCT, and qualitative assessments. 33 Only the CMyLife application38,40,43 had progressed from conceptualisation to trial. Other applications39,42,44 in this review were in their pre-testing phase or had not advanced beyond the pilot study. Despite the incorporation of expert feedback in four39–41,44 of the six analysed applications, the overall efficacy of these studies did not yield significant improvements in clinical and behavioural outcomes. One possible explanation is the small sample sizes, which may not provide adequate statistical power to identify differences. Additionally, the heterogeneity of outcome measures used across the studies complicates comparisons and conclusions regarding the overall efficacy of these applications, consistent with findings from Flaucher et al.'s review of breast cancer applications. 74
Future research direction
Further development of mHealth applications should prioritise well-designed, large-scale randomised controlled trials to rigorously evaluate their clinical and behavioural efficacy for patients receiving oral SACT. These trials should move beyond pre-testing and pilot phases, incorporating adequately powered and diverse participant groups to generate robust evidence for integration into standard medical practice.
In addition, future research should examine the long-term user engagement and adherence to mHealth applications, with a focus on addressing key implementation challenges such as technical glitches, notification fatigue, and difficulties with daily integration. For example, one potential strategy to limit the volume of notifications is to implement machine learning algorithms by adapting to individual patient medication regimens and symptoms over time, thus providing tailored alerts. The development and validation of standardised measures for assessing acceptability and efficacy will also be essential to enhance comparability across studies.
Implications for practice and policy
Our findings suggest that mHealth applications have the potential to facilitate remote monitoring of side effects, symptoms, and adherence in patients undergoing oral SACT, thereby enabling healthcare providers to better track patients’ symptom and adherence beyond traditional clinical settings. The insights from this review regarding application content and contextual factors provide valuable guidance for future research, development, and implementation strategies. Specifically, incorporating an aesthetically pleasing interface aligned with user experience (UX) principles can significantly enhance user engagement. 75
Additionally, concerns about infrequent updates, consistent with findings by Gutierrez et al., 19 underscore the need for ongoing maintenance and timely updates to ensure that applications remain aligned with evolving clinical guidelines, especially in the rapidly advancing field of haematological malignancies. Addressing these challenges will be critical for the successful integration of mHealth solutions into routine practice, facilitating personalised care delivery and improving the organisation and management of treatment plans for patients in their home environments.
Limitations
This review has several limitations, including the exclusive focus on studies published in English, potentially overlooking relevant research in other languages. The small sample sizes in the included studies may also limit the statistical power to substantiate findings. The included studies demonstrated substantial diversity across several key parameters, including sample populations, haematological cancer types, app features, and study designs. This variability restricts direct comparison and generalisability of the findings. Nevertheless, it underscores the broad applicability of mHealth interventions across different clinical and demographic contexts. Additionally, the variability in assessment measures used to evaluate mHealth app acceptability (SUS, Enlight, Likert-based satisfaction ratings) complicates comparison across studies and renders a meta-analysis infeasible. Consequently, the evidence regarding the efficacy and acceptability of mHealth applications for patients with haematological malignancies remains limited, highlighting opportunities for future research to bridge these gaps.
Conclusion
The available evidence indicates that mHealth applications are generally acceptable and show promise in supporting the self-management of oral SACTs among patients with haematological malignancies. However, usability challenges such as notification fatigue, and inadequate integration into daily routine, remain key barriers that must be addressed to realise the full potential of these applications. Current evidence on clinical efficacy is limited by heterogeneous outcome measures, and a lack of adequately powered RCTs. Future research should prioritise rigorous trial designs with standardised outcome metrics to determine the true impact of mHealth application interventions on patient outcomes. Moreover, future interventions should focus on enhancing personalisation such as using machine learning algorithms to adapt to patients’ evolving medications to potentially reduce notification fatigue, and integration into patients’ ongoing care to sustain long-term engagement.
