Intelligent user assistance for cost effective usage of mobile phone

Environmental contextA widespread pollutant in groundwater, rivers and lakes is nitrite, which is commonly determined batchwise by using colourimetry. The batchwise method, however, requires relatively large and expensive instrumentation, and hence is unsuitable for in-field measurements. This work introduces a simple and portable colourimetric analyser based on a mobile-phone camera for monitoring nitrite concentrations in environmental water samples. AbstractA cost-effective and portable colourimetric analyser installed on a mobile phone was used to measure nitrite in water samples in Chiang Mai City, Thailand. The colourimetric detection was based on the Griess reaction, in which nitrite ion reacts with sulfanilic acid under acidic conditions to produce a diazonium salt that further reacts with N-(1-naphthyl)-ethylenediamine dihydrochloride to form a red–violet azo dye. Under controlled conditions using a light-tight box with LED flash lights, images of the red–violet solution were captured using a built-in camera and further analysed by a program, Panalysis, on the mobile phone. The calibration graph was created by measuring the red colour intensity of a series of standard nitrite solutions from 0.09–1.8 mg N L−1. The calibration equation was then automatically stored for nitrite analysis. The results demonstrated good performance of the mobile phone analyser as an analytical instrument. The accuracy (RE <4%) and precision (RSD ≤ 1%, intra- and inter-day) were also obtained with a detection limit of 0.03 mg N L−1 and a sample throughput of 40 samples per hour. Our results establish this simple, inexpensive and portable device as a reliable in-field monitor of nitrite in environmental waters.

Extension methodologies for communicating technologies to farmers have evolved over the past 200 years from so-called traditional methodologies to more advanced and technology-based methodologies that enable extension staff to reach many people within the shortest possible time in a more effective and efficient way. Though traditional methods are still relevant and effective, current trends require the use of more innovative and cost-effective methodologies. This paper examined the perceptions of farmers on the use of ICTs in Extension Service delivery in the Northern Region of Ghana. Ninety farmers were randomly sampled from 6 communities in 6 districts in the region. Data was collected using semi-structured questionnaire. A 5-point Likert scale was used to determine farmers’ perceived effects of ICT on extension delivery. Data were analysed using means, standard deviations, t-test, frequencies and percentages. The most widely used ICTs by farmers are radio, mobile phone and television. Farmers perceive the use of mobile phone to have resulted in timely delivery of information, increased interaction among farmers and between farmers and AEAs and effective use of time and energy by AEAs. The use of radio has improved adoption of technologies and enhanced farmers’ awareness of innovations. It is concluded mobile phone, radio and television are used widely in the region and have very positive effects on extension service delivery.

BACKGROUND The diagnosis of paroxysmal events in infants is often challenging. Reasons include the child’s inability to express discomfort and the inability to record video electroencephalography at home. The prevalence of mobile phones, which can record videos, may be beneficial to these patients. In China, this advantage may be even more significant given the vast population and the uneven distribution of medical resources. OBJECTIVE The aim of this study is to investigate the value of mobile phone videos in increasing the diagnostic accuracy and cost savings of paroxysmal events in infants. METHODS Clinical data, including descriptions and home videos of episodes, from 12 patients with paroxysmal events were collected. The investigation was conducted in six centers during pediatric academic conferences. All 452 practitioners present were asked to make their diagnoses by just the descriptions of the events, and then remake their diagnoses after watching the corresponding home videos of the episodes. The doctor’s information, including educational background, profession, working years, and working hospital level, was also recorded. The cost savings from accurate diagnoses were measured on the basis of using online consultation, which can also be done easily by mobile phone. All data were recorded in the form of questionnaires designed for this study. RESULTS We collected 452 questionnaires, 301 of which met the criteria (66.6%) and were analyzed. The mean correct diagnoses with and without videos was 8.4 (SD 1.7) of 12 and 7.5 (SD 1.7) of 12, respectively. For epileptic seizures, mobile phone videos increased the mean accurate diagnoses by 3.9%; for nonepileptic events, it was 11.5% and both were statistically different (P=.006 for epileptic events; P<.001 for nonepileptic events). Pediatric neurologists with longer working years had higher diagnostic accuracy; whereas, their working hospital level and educational background made no difference. For patients with paroxysmal events, at least US $673.90 per capita and US $128 million nationwide could be saved annually, which is 12.02% of the total cost for correct diagnosis. CONCLUSIONS Home videos made on mobile phones are a cost-effective tool for the diagnosis of paroxysmal events in infants. They can facilitate the diagnosis of paroxysmal events in infants and thereby save costs. The best choice for infants with paroxysmal events on their initial visit is to record their events first and then show the video to a neurologist with longer working years through online consultation.

IntroductionPostnatal depression is known to cause disability and suffering in women and negative consequences both for their infants and their families, with huge costs globally. Several studies from low and middle income countries (LAMIC) have demonstrated that effectively delivered psychological interventions are cost effective for improving maternal and child health, but access to these interventions is limited in both the low and high income countries.ObjectiveThe objective of the study is to develop and test a mobile phone-based intervention (TechMotherCare), which will include components of cognitive behavioural therapy (CBT) and child development related psychoeducation.AimThe aim of the study is to examine the feasibility and acceptability of the TechMotherCare intervention.MethodsA total of 36 participants will be recruited from health centers in Karachi, Pakistan for this 2-arm randomized pilot study. The TechMotherCare App intervention will be based on principles of CBT and learning-through-play (LTP) a parenting intervention and will assess the real-time depressive symptoms of participants and respond, using intelligent real time therapy (iRTT) dependent on symptoms reported by participants.ResultsOutcome assessments will be completed after 3 months (end of intervention). In-depth qualitative interviews will also be conducted with participants pre- and post-intervention. The trial is ongoing and we will present both the qualitative and quantitative results.ConclusionsThe results of this pilot trial will inform the design of a larger randomised controlled trial using a mobile based technology platform to address the huge treatment gap in LAMICs.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Consumer Device

Mobile phones are becoming the most widespread personal consumer device. Yet, offering mobile access anywhere, anytime for anybody poses new challenges to usability. So far there is little research on how to customize usability heuristics to the specific characteristics of mobile phone applications. Therefore, this article presents a set of tailored usability heuristics based on a systematic literature review. In order to facilitate the usage of these heuristics, the authors design and validate a measurement instrument (checklist) and scale. The checklist has been validated through an empirical study in which the results of 247 heuristic evaluations have been statistically analyzed using Item Response Theory. Based on the results, the measurement items have been calibrated and a standardized measurement scale has been constructed. The results can be used to measure usability of mobile phone applications from early on in the design process, and, thus, facilitate evaluations in a cost-effective way.

Abstract Background Strengthening surveillance systems to collect near-real-time case-based data plays a fundamental role in achieving malaria elimination in the Greater Mekong Subregion (GMS). With the advanced and widespread use of digital technology, mHealth is increasingly taking a prominent role in malaria surveillance systems in GMS countries, including Myanmar. In Myanmar’s malaria elimination program, an mHealth system called Malaria Case-based Reporting (MCBR) has been applied for case-based reporting of malaria data by integrated community malaria volunteers (ICMVs). However, the sustainability of such mHealth systems in the context of existing malaria elimination programs in Myanmar is unknown. Methods Focus group discussions were conducted with ICMVs and semi-structured in-depth interviews were conducted with malaria program stakeholders from Myanmar’s Ministry of Health and Sports and its malaria program implementing partners. Thematic (deductive followed by inductive) analysis was undertaken using a qualitative descriptive approach. Results Technological and financial constraints such as inadequate internet access, software errors, and insufficient financial resources to support mobile phone-related costs have hampered users’ access to MCBR. Poor system integrity, unpredictable reporting outcomes, inadequate human resources for system management, and inefficient user support undermined the perceived quality of the system and user satisfaction, and hence its sustainability. Furthermore, multiple parallel systems with functions overlapping those of MCBR were in use. Conclusions Despite its effectiveness and efficiency in malaria surveillance, the sustainability of nationwide implementation of MCBR is uncertain. To make it sustainable, stakeholders should deploy a dedicated human workforce with the necessary technical and technological capacities; secure sustainable, long-term funding for implementation of MCBR; find an alternative cost-effective plan for ensuring sustainable system access by ICMVs, such as using volunteer-owned mobile phones for reporting rather than supporting new mobile phones to them; and find a solution to the burden of multiple parallel systems.

Abstract Introduction: Mobile health (mHealth) programmes offer opportunities to improve sexual and reproductive health (SRH) for adolescents by providing information. Researchers define mHealth as a “medical and public health practice supported by mobile devices”. mHealth is increasingly used to deliver health interventions including adolescent SRH. However, knowledge gaps remain regarding the utilization and effectiveness of these programmes. This study reports findings of a qualitative study carried out in Homabay County, Kenya. Purpose: We aimed to establish if mHealth would facilitate access of SRH information by adolescents, and whether adolescents would participate in SRH-related content delivered on mobile phones, based on their experiences and existing constraints.Methods: This was a qualitative exploratory study seeking to gain an understanding of the experiences of adolescents concerning their mobile phone ownership, access and use. The study population included adolescents, parents, teachers and health care workers and community health volunteers (CHVs). Data were collected through 25 Focus Group Discussions (FGDs) and 19 key informant interviews (KIIs). The FGDs consisted of five groups each for girls, boys, fathers, mothers and CHVs. We purposively selected five primary school heads, five secondary school heads and nine health facilities in-charges for KIIs. Data were analyzed through thematic and qualitative content analysis.Results: Mobile phone use was frequent among adolescents accessing phones from parents and friends. The most popular use of mobile phones was short messaging service (SMS) with girls and boys citing chatting, SMS and watching movies. Service providers emphasized accessing health knowledge. Teachers emphasized accessing SRH information. All respondent categories highlighting ease of access and potential reach to large numbers of adolescents and hence an effective and efficient approach. Respondents lauded the potential of mobile phones to promote learning of useful SRH information among adolescents to influence their behavior formation, modification and or change by learning about diseases and receiving advice. Mobile phones overcame barriers experienced by adolescents when seeking sensitive SRH information and services such as stigma, discrimination, and lack of privacy and confidentiality. Conclusion: Mobile phones can provide safe, accurate, cost-effective, and timely SRH information and services tailored to the needs of adolescents to influence their behavior
