Smartphone-based application for self-management of patients with colorectal cancer: development and usability evaluation

A randomized controlled trial of a digital lifestyle intervention involving postoperative patients with colorectal cancer

Few studies have investigated quality of life (QoL) improvements in patients with colorectal cancer or the benefits of digital healthcare interventions. This randomized controlled trial assessed the impact of mobile applications on postoperative QoL in patients scheduled for curative surgery for colorectal cancer. Patients were randomized into three intervention groups (each using a different mobile application for postoperative lifestyle management) and a control group. QoL was evaluated using the European Quality of Life-5 Dimensions (EQ-5D), with physical and metabolic parameters and fat/muscle areas measured preoperatively, and every six months postoperatively. At six months, no significant differences in the EQ-5D scores from baseline were observed across groups. Intervention Group C showed a significant increase in skeletal muscle area compared to the control group (P = 0.046). Overall, mobile application use had a minimal effect on postoperative health-related QoL, warranting further research on their efficacy and compliance rates.

Discussion on the optimization of personalized medication using information systems based on pharmacogenomics: an example using colorectal cancer

Pharmacogenomics (PGx) is a powerful tool for clinical optimization of drug efficacy and safety. However, due to many factors affecting drugs in the real world, PGx still accounts for a small proportion of actual clinical application scenarios. Therefore, based on the information software, pharmacists use their professional advantages to integrate PGx into all aspects of pharmaceutical care, which is conducive to promoting the development of personalized medicine. In this paper, the establishment of an information software platform is summarized for the optimization of a personalized medication program based on PGx. Taking colorectal cancers (CRC) as an example, this paper also discusses the role of PGx in different working modes and participation in drug management of CRC patients by pharmacists with the help of information systems. Finally, we summarized the recommendations of different PGx guidelines to provide reference for the follow-up personalized pharmaceutical care.

Patients' Experienced Usability and Satisfaction With Digital Health Solutions in a Home Setting: Instrument Validation Study

Background

The field of digital health solutions (DHS) has grown tremendously over the past years. DHS include tools for self-management, which support individuals to take charge of their own health. The usability of DHS, as experienced by patients, is pivotal to adoption. However, well-known questionnaires that evaluate usability and satisfaction use complex terminology derived from human-computer interaction and are therefore not well suited to assess experienced usability of patients using DHS in a home setting.

Objective

This study aimed to develop, validate, and assess an instrument that measures experienced usability and satisfaction of patients using DHS in a home setting.

Methods

The development of the "Experienced Usability and Satisfaction with Self-monitoring in the Home Setting" (GEMS) questionnaire followed several steps. Step I consisted of assessing the content validity, by conducting a literature review on current usability and satisfaction questionnaires, collecting statements and discussing these in an expert meeting, and translating each statement and adjusting it to the language level of the general population. This phase resulted in a draft version of the GEMS. Step II comprised assessing its face validity by pilot testing with Amsterdam University Medical Center's patient panel. In step III, psychometric analysis was conducted and the GEMS was assessed for reliability.

Results

A total of 14 items were included for psychometric analysis and resulted in 4 reliable scales: convenience of use, perceived value, efficiency of use, and satisfaction.

Conclusions

Overall, the GEMS questionnaire demonstrated its reliability and validity in assessing experienced usability and satisfaction of DHS in a home setting. Further refinement of the instrument is necessary to confirm its applicability in other patient populations in order to promote the development of a steering mechanism that can be applied longitudinally throughout implementation, and can be used as a benchmarking instrument.

Effect of self-efficacy on self-management ability for colorectal cancer patients with stoma: a path analysis

PURPOSE

Colorectal cancer threatens health and causes heavy social burdens. The purpose of this study is to analyze the pathway model for the effect of self-efficacy on self-management ability in colorectal cancer patients with stoma.

METHODS

A cross-sectional study was conducted from December 2022 to April 2023, with a convenience sample of 422 colorectal cancer patients with stoma at six tertiary grade A hospitals in Shandong Province, China. Statistical analysis was undertaken using SPSS 26.0 and Amos 24.0 software. A pathway model based on individual and family self-management theories was developed and analyzed by collecting data through onsite survey and online survey.

RESULTS

Chinese colorectal cancer patient's self-management ability score is 105.19 (17.19), which shows medium-level self-management ability. The self-efficacy of colorectal cancer patients with a stoma is influenced by social support, which ultimately leads to changes in their self-management ability.

CONCLUSION

The findings may help healthcare professionals to identify the factors that influence self-management skills of colorectal cancer patients with stoma and provide a basis for developing interventions.

Determinants of the implementation of eHealth-based long-term follow-up care for young cancer survivors: a qualitative study

BACKGROUND

eHealth may help closing gaps in the long-term follow-up care of former young age cancer patients. While its introduction to medical aftercare appears promising, it also faces obstacles in the course of its implementation. This study explored what prospective eHealth applications have to achieve and what facilitating and hindering factors are associated with the implementation of them.

METHODS

A qualitative, explorative-descriptive design involving semi-structured interviews was used in this study. General practitioners (GPs) from urban and rural areas as well as former cancer patients were recruited and interviewed. The interview guide focused on expectations of telemedical care services for the patient group of children and adolescents as well as potential facilitating and hindering factors of the implementation of telemedical care services for former cancer patients. Interviews were recorded, transcribed and analyzed on the basis of qualitative content analysis as described by Kuckartz.

RESULTS

Empiric saturation was reached after 25 interviews, respectively. The age of the physicians surveyed at the time of the interviews ranged from 27 to 71 years, with an average of 42 years. The former patients ranged in age from 21 to 43 at the time of participation, with an average age of 34. The age at diagnosis ranged from 3 to 31 years. eHealth services were considered an effective way to maintain continuity of care and improve the health literacy of cancer survivors. Cooperation with health insurance companies and gamification-elements were regarded as beneficial for the introduction of eHealth structures. Poor interface compatibility, insufficient network coverage and lack of digital literacy were valued as potential barriers.

CONCLUSIONS

If properly introduced, eHealth shows the potential to provide stakeholders with tools that increase their self-efficacy and ability to act. As the technology continues to advance, our data provides application-oriented factors for tailored implementation strategies to bring eHealth into the field.

Acceptability, Effectiveness, and Roles of mHealth Applications in Supporting Cancer Pain Self-Management: Integrative Review

BACKGROUND

 Cancer pain remains highly prevalent and persistent throughout survivorship, and it is crucial to investigate the potential of leveraging the advanced features of mobile health (mHealth) apps to empower individuals to self-manage their pain.

OBJECTIVE

 This review aims to comprehensively understand the acceptability, users' experiences, and effectiveness of mHealth apps in supporting cancer pain self-management.

METHODS

 We conducted an integrative review following Souza and Whittemore and Knafl's 6 review processes. Literature was searched in PubMed, Scopus, CINAHL Plus with Full Text, PsycINFO, and Embase, from 2013 to 2023. Keywords including "cancer patients," "pain," "self-management," "mHealth applications," and relevant synonyms were used in the search. The Johns Hopkins research evidence appraisal tool was used to evaluate the quality of eligible studies. A narrative synthesis was conducted to analyze the extracted data.

RESULTS

 A total of 20 studies were included, with the overall quality rated as high (n=15) to good (n=5). Using mHealth apps to monitor and manage pain was acceptable for most patients with cancer. The internal consistency of the mHealth in measuring pain was 0.96. The reported daily assessment or engagement rate ranged from 61.9% to 76.8%. All mHealth apps were designed for multimodal interventions. Participants generally had positive experiences using pain apps, rating them as enjoyable and user-friendly. In addition, 6 studies reported significant improvements in health outcomes, including enhancement in pain remission (severity and intensity), medication adherence, and a reduced frequency of breakthrough pain. The most frequently highlighted roles of mHealth apps included pain monitoring, tracking, reminders, education facilitation, and support coordination.

CONCLUSIONS

 mHealth apps are effective and acceptable in supporting pain self-management. They offer a promising multi-model approach for patients to monitor, track, and manage their pain. These findings provide evidence-based insights for leveraging mHealth apps to support cancer pain self-management. More high-quality studies are needed to examine the effectiveness of digital technology-based interventions for cancer pain self-management and to identify the facilitators and barriers to their implementation in real-world practice.

Smartphone applications for nutrition Support: A systematic review of the target outcomes and main functionalities

INTRODUCTION

A proper nutrition is essential for human life. Recently, special attention on this topic has been given in relation to three health statuses: obesity, malnutrition and specific diseases that can be related to food or treated with specific diets. Mobile technology is often used to assist users that wish to regulate their eating habits, and identifying which fields of application have been explored the most by the app developers and which main functionalities have been adopted can be useful in view of future app developments.

METHODS

We selected 322 articles mentioning nutrition support apps through a literature database search, all of which have undergone an initial screening. After the exclusion of papers that were already reviews, not presenting apps or not focused on nutrition, not relevant or not developed for human subjects, 100 papers were selected for subsequent analyses that aimed at identifying the main treated conditions, outcome measures and functionalities implemented in the Apps.

RESULTS

Of the selected studies, 33 focus on specific diseases, 24 on obesity, 2 on malnutrition and 41 on other targets (e.g., weight/diet control). Type 2 diabetes is the most targeted disease, followed by gestational diabetes, hypertension, colorectal cancer and CVDs which all were targeted by more than one app. Most Apps include self-monitoring and coaching functionalities, educational content and artificial intelligence (AI) tools are slightly less common, whereas counseling, gamification and questionnaires are the least implemented. Body weight and calories/nutrients were the most common general outcome measures, while glycated hemoglobin (HbA1c) was the most common clinical outcome. No statistically significant differences in the effectiveness of the different functionalities were found.

CONCLUSION

The use of mobile technology to improve nutrition has been widely explored in the last years, especially for weight control and specific diseases like diabetes; however, other food-related conditions such as Irritable Bowel Diseases appear to be less targeted by newly developed smartphone apps and their related studies. All different kinds of functionalities appear to be equally effective, but further specific studies are needed to confirm the results.

Digital postoperative follow-up after colorectal resection: a multi-center preliminary qualitative study on a patient reporting and monitoring application

The development of minimally invasive colorectal surgery in the last decades led to a decrease in length of hospital stay. However, readmission and postoperative complications were still observed. Several studies have shown that close postoperative follow-up is required to decrease postoperative morbidity through patient education and by detecting early signs of complications. To help in this task, multiple monitoring programs have been set up to follow patients at home, allowing detection of several complications at an early stage. To evaluate acceptance, satisfaction, usability, compliance and safety of a mobile application following postoperative colorectal patients during the first 15 days post-discharge from hospital. A mobile application enabling the communication between the patient and medical staff during the recovery phase was developed and tested in four hospitals. Patients who underwent a colorectal resection were included in this prospective qualitative study. Questionnaires to assess satisfaction and usability were handed out to patients at the end of the test period. Overall, 118 patients (52% females, median age 52.5 years) were included. Median adherence-rate during 15 days was 89.6%. Satisfaction-rate for the application was 76% and usability was high. Overall, 1220 notifications were collected, of which 722 were orange, 466 red and 32 purple, colours used to rate the severeness of complaints. We analyzed the most common notifications, showing trends in different subgroups of the study with higher risks of complications (pain (409 notifications), abnormal stools (196 notifications), and wound problems (118 notifications)). A mobile application could be used to follow patients at home after colorectal resection. Future studies should evaluate whether these applications can detect complications and prevent readmission.

Mobile-Based Application Interventions to Enhance Cancer Control and Care in Low- and Middle-Income Countries: A Systematic Review

Objective: To identify and appraise mobile-based application (mAPP) interventions that have been used to support cancer control and care in low- and middle-income countries (LMICs). Methods: Four electronic databases were systematically searched for studies that reported primary research findings related to mAPP interventions applied in oncology settings in LMICs. A narrative synthesis was performed using the Mhealth Index and Navigation Database as an analytical framework. Results: Twenty studies reporting 18 cancer control and care mAPPs were included in this review. Among these mAPPs, ten focused on prevention, screening and early detection of cancer, five provided information to optimise supportive and palliative care, two provided support to assist treatment-shared decision-making and one covered information for follow-up and survivorship care. Conclusion: Cancer mAPP interventions are gradually gaining attention in LMICs as they provide unique resources for empowering and strengthening the role of people with cancer in their own care. To enhance cancer control, a focus on prevention and early detection is important; however, more mAPP interventions related to cancer treatment, follow-up and survivorship are also needed to enable more cost-effective cancer care.

Effects of an interactive coaching intervention on quality of life and psychological factors for colorectal cancer survivors: A single group pre and posttest design

OBJECTIVE

To develop and evaluate the effects of an interactive coaching intervention, using a self-management mobile application, on quality of life and physical and psychological factors for colorectal cancer survivors.

METHODS

We developed a self-management mobile application providing social support services for post-treatment CRC survivors and evaluated its effects through baseline and post-intervention surveys. Using the biopsychosocial holistic model as the theoretical framework, automated interactive coaching technology was applied for six weeks to provide supportive services tailored for each user. To evaluate the effects of the application, self-efficacy, health practice index, depression, fear of cancer recurrence, and quality of life measures were administered to participants. A total of 34 men and 5 women were included in the analysis.

RESULTS

Participants' mean age were 54.10 years and 78% of them had been diagnosed within the last five years. There were significant increases in self-efficacy (z = 2.09, p = .04), health practice index (t = 2.35, p = .02), and quality of life (t = 2.03, p = .05). More specifically, the emotional functional score increased (z = 2.23, p = .03) while both of the total symptom score (t = 2.10, p = .04) and the fatigue symptom score (z = 2.54, p = .01) decreased after six weeks of using the mobile application.

CONCLUSIONS

Interventions supporting colorectal cancer survivors' self-management are critical for addressing the challenges they face after treatment and improving their quality of life. Providing social support through mobile applications could be a good strategy in terms of usability and effectiveness.

User-Centered Development of a Mobile App to Assess the Quality of Life of Patients With Cancer: Iterative Investigation and Usability Testing

BACKGROUND

The treatment for cancer can have a negative impact not only on physical well-being but also on mental health and the quality of life (QoL). Health apps enable the monitoring of different parameters, but to date, there are only few that support patients with cancer and none that focuses on the assessment of QoL. Furthermore, patients as stakeholders are often only integrated at the late stage of the development process, if at all.

OBJECTIVE

The aim of this research was to develop and evaluate a smartphone app (Lion-App) to enable patients with cancer to autonomously measure the QoL with an iterative, user-centered approach.

METHODS

Patients with cancer were involved in a 3-stage process from conceptualization to the point when the app was available on the tester's private device. First, focus groups with members (N=21) of cancer support groups were conducted to understand their expectations and needs. Thereafter, individual tests were performed. After developing a prototype that incorporated findings from the focus groups, a second test cycle was conducted, followed by a beta test lasting 2 months. In our app, the QoL can be assessed via a patient diary and an integrated questionnaire. Through all stages, usability was evaluated using the modular extended version of the User Experience Questionnaire (UEQ+), including the calculation of a key performance indicator (KPI). If possible, the impact of sex on the results was evaluated. As part of the beta test, usage rates as well as age-dependent differences were also assessed.

RESULTS

A total of 21 participants took part in the initial 3 focus groups. In the subsequent usability testing (N=18), 17 (94%) participants rated their impression through the UEQ+, with a mean KPI of 2.12 (SD 0.64, range: -3 to 3). In the second usability test (N=14), the mean KPI increased to 2.28 (SD=0.49). In the beta test, the usage rate of 19 participants was evaluated, of whom 14 (74%) also answered the UEQ+ (mean KPI 1.78, SD 0.84). An influence of age on the number of questionnaire responses in Lion-App was observed, with a decrease in responses with increasing age (P=.02). Sex-dependent analyses were only possible for the first usability test and the beta test. The main adjustments based on user feedback were a restructuring of the diary as well as integration of a shorter questionnaire to assess the QoL.

CONCLUSIONS

The iterative, user-centered approach for development and usability testing resulted in positive evaluations of Lion-App. Our app was rated as suitable for everyday use to monitor the QoL of patients with cancer. Initial results indicated that the sex and age of participants seem to play only a minor role.

Remote Monitoring of Colorectal Cancer Survivors Using a Smartphone App and Internet of Things-Based Device: Development and Usability Study

BACKGROUND

Patients with colorectal cancer who undergo surgery face many postoperative problems. These problems include the risk of relapse, side effects, and long-term complications.

OBJECTIVE

This study sought to design and develop a remote monitoring system as a technological solution for the postdischarge care of these patients.

METHODS

This research was conducted in 3 main steps: system feature extraction, system design, and evaluation. After feature extraction from a systematic review, the necessary features were defined by 18 clinical experts in Iran. In the next step, the architecture of the system was designed based on the requirements; the software and hardware parts of the system were embedded in the architecture, then the software system components were drawn using the unified modeling language diagrams, and the details of software system implementation were identified. Regarding the hardware design, different accessible hardware modules were evaluated, and suitable ones were selected. Finally, the usability of the system was evaluated by demonstrating it over a Skype virtual meeting session and using Nilsen's usability principles.

RESULTS

A total of 21 mandatory features in 5 main categories, including patient information registration, periodic monitoring of health parameters, education, reminders, and assessments, were defined and validated for the system. The software was developed using an ASP.Net core backend, a Microsoft SQL Server database, and an Ionic frontend alongside the Angular framework, to build an Android app. The user roles of the system included 3 roles: physicians, patients, and the system administrator. The hardware was designed to contain an Esp8266 as the Internet of Things module, an MLX90614 infrared temperature sensor, and the Maxim Integrated MAX30101 sensor for sensing the heartbeat. The hardware was designed in the shape of a wristband device using SolidWorks 2020 and printed using a 3D printer. The firmware of the hardware was developed in Arduino with the capability of firmware over the air. In evaluating the software system from the perspective of usability, the system received an average score of 3.8 out of 5 from 4 evaluators.

CONCLUSIONS

Sensor-based telemonitoring systems for patients with colorectal cancer after surgery are possible solutions that can make the process automatic for patients and caregivers. The apps for remote colorectal patient monitoring could be designed to be useful; however, more research regarding the developed system's implementation in clinic settings and hospitals is required to understand the probable barriers and limitations.
