  • mHealth’s proven impact still seems elusive

    Africa has an expanding, diverse mHealth core to its eHealth initiatives. The Journal of Medical Internet Research (JMIR) found limited evidence of mHealth’s impact, and hinted that in low-income countries, mHealth’s still at an early development stage.

    JMIR’s systematic review covered 10,689 mHealth articles, including 23 systematic reviews of 371 studies with over 79,609 patients. Seventeen reviews included studies of low- and middle-income countries’ initiatives. 

    SMS for a wide range of purposes seems to be the most common type of mHealth. It includes reminders, alerts, educations, motivation and illness prevention. Ten reviews gave them an Assessment of Multiple Systematic Reviews (AMSTAR) score of 0 to 4, low quality. Seven were rated as moderate quality, an AMSTAR score of 5 to 8. Six were rated as high quality, an AMSTAR score of 9 to 11. 

    mHealth for  chronic disease management scored well for impacts of:

    Improved symptoms and peak flow variability in asthma patients and fewer hospital admissions and improving forced expiratory volume in one secondImproving Chronic Obstructive Pulmonary Diseases (COPD) symptomsImproving heart failure symptoms and fewer deaths and hospital admissionsImproving glycaemic control in diabetes patientsImproving blood pressure in hypertensive patientsReducing weight in overweight and obese patientsBetter attendance ratesBetter adherence to tuberculosis and human immunodeficiency virus therapy in some scenarios, with evidence of decreased viral loads.

    While these are positive results, the benefits may still be moderate.  JMIR concluded that “Evidence for efficacy is still limited. In general, the methodological quality of the studies included in the systematic reviews is low. For some fields, its impact is not evident, the results are mixed, or no long-term studies exist.”

    The lack of reliable evidence doesn’t mean that Africa should slow down its mHealth investment. Instead, it means it should set up a reliable methodology to reveal the range of good and bad impacts. Lessons from these will be invaluable.

  • A smart watch can detect epilepsy

    Epilepsy is a leading serious neurological condition worldwide.  It has particularly significant physical, economic and social consequences.  Recognising the need for an intervention, Empatica Inc. has developed a smart watch to detect seizures in epileptic patients.  They’re calling it Embrace.

    Embrace uses machine learning algorithms to monitor and detect different seizure types, including grand mal or generalised tonic-clonic seizures. Electrodermal Activity (EDA)* sensors in the watch are used to measure multiple indicators of a seizure. 

    It’s also accompanied by an app that will send an alert, via text message, to a healthcare provider or caregiver once a seizure is detected.  Additionally, the app serves as an electronic seizure diary and health record for the user.

    During a clinical study involving 135 epileptic patients, Embrace’s algorithm was shown to detect 100% of the seizures, including the 40% of silent seizures that were unreported in patient clinical diaries.  Following this, the smart watch has received FDA approval as well as approval in Europe as a medical device for epileptic monitoring.

    Embrace’s high sensitivity is revolutionising seizure reporting.  It serves as a much awaited alternative to wearing an EEG, that is automated, and isn’t bulky or cumbersome to wear.

  • Three mHealth apps help with treatment adherence

    Adherence to medication is an increasing problem in primary health care in Africa. It is important for many things, from birth control to antibiotics to ARTs. When medications are forgotten or skipped, most treatments are no longer as effective.  This becomes both costly for the healthcare system and detrimental to a patient’s health.

    Factors impacting adherence are multifaceted and include social, economic and psychological motives.  A sub-Saharan study in 2017 reported the most common barriers to adherence were;

    ForgettingLack of access to adequate foodStigma and discriminationSide-effects of the medicationTraveling

    With the uptake of smartphones in Africa, mHealth apps targeting treatment adherence could be a simple solution.  Here are the top 3 downloaded treatment adherence apps on Google Play Store. 


    This app turns patient education into an adventure game and shows patients the importance of sticking to a treatment schedule.


    In addition to medication reminders, this app will notify friends and family if the user defaults. Medisafe also launched a low-tech version that sends reminders through automated phone calls and text messages. 


    After logging their medications on the MyTherapy app, users will receive reminders and alerts to take their medications.  Other features on the app include symptom tracking, healthy lifestyle tips and friends and family support groups.

    Improved adherence means a healthier society and ultimately, a reduced burden on healthcare systems.  Moreover, access to adherence data from these apps could help doctors and policy makers make better informed decisions about how to improve the healthcare system.

  • EMGuidance web-platform to simplify medication look-up in South Africa

    Since the launch of their clinical support platform in 2016, EMGuidance has become one of the most popular medical apps in South Africa, even extending to other parts of the globe.  Its popularity is largely due to the comprehensive, up-to-date and locally relevant clinical guides and protocols made easily available to health professionals.

    In fact, the response from health professionals has been so great that EMGuidance is now available as a web-based platform.  The web-based platform essentially functions as a Google search engine with a twist.  This niche search engine only returns locally relevant information – fulfilling a great gap in clinical support tools in South Africa.  Health professionals will now be able to search for relevant South African therapies by trade name, active ingredient or registered indication. 

    Realising the potential for other African countries, EMGuidance has launched a slim-line version of their tool in Sierra Leone.  The positive response from the local community has spurred plans to expand to Kenya, Tanzania and other African countries.  It’s activities and initiatives like EMGuidance that will springboard eHealth in Africa to first-world healthcare delivery.

  • Ghana will have a national telemedicine service next year

    Pilotitis become a phenomenon a few years ago as scaling-up eHealth pilots became too challenging. Good scale-up news is the recent  telemedicine initiative by Ghana Health Service and The Novartis Foundation, They’ve announced the successful integration and scale-up of a telemedicine service. National coverage’s planned for 2019. 

    The 24-hour telemedicine service uses mHealth for community health workers to consult specialist health professionals at teleconsultation centres on a range of health topics, including emergencies. It builds from the telemedicine pilot started in 2011 in the Ashanti Region’s Amansie West District.

    An important lesson for other African countries’s the timescale. Seven years may seem like a long time, but eHealth does take time to come to fruition. Over the period, telemedicine has encountered some specific changes. mHealth opportunities have replaced conventional conferencing technology, now obsolete and looking a bit clumsy and chunky.

    Ghana may have set a standard for other African countries to follow. It represents a considerable technological achievement in modernising and transforming healthcare. 

  • mHealth to drive Cote d’Ivoire's immunisation project

    Like falling snow, announcements at the World Economic Forum come thick and fast. Taking place in Davos Switzerland, Thursday 25th, 2018, one of the world’s leading telecommunications operators, Orange SA and the Vaccine Alliance Gavi announced a partnership with Côte d’Ivoire’s Ministry of Health to boost immunisation rates in the countries’ regions and districts with the lowest vaccine coverage.

    A report in Ventures Africa says it’s a joint US$ 5.47m five-year project. Half the money’s from the Gavi Matching Fund, a mechanism financed by the Bill & Melinda Gates Foundation to motivate and provide incentives for private sector investment in immunisation. It builds from Gavi’s longstanding role in the country starting form 2001, Gavi supported Côte d’ Ivoire in introducing eleven vaccines.

    It all fits with the M-Vaccin Côte d’ Ivoire initiative. It uses Orange mobile technology to inform parents about the importance of vaccination. Sending text and voice messages in local languages and targeting messages about keeping immunisation sessions are standard themes. Reminders of their children’s schedules and dates are the main goals.

    The initiative should be transferrable to all African countries. It’ll be good to see vaccination rates above 95% soon.

  • South Africa’s mHealth has opportunities and bigger barriers

    Much has been made of the growth in mobile phones and their opportunities for Africans’ better health. A qualitative study in Science Direct found that there may not be a high positive correlation. It says while mobile phones have been evolving to fill South Africa’s primary care services gaps, there are barriers to access. Poor digital infrastructure and low digital literacy are two main longstanding inhibitors. 

    The study investigated mobile phone use by a wide range of people. It included patients with chronic diseases, pregnant women and health workers in Mpumalanga, South Africa. In 2014, semi-structured in-depth interviews were completed with 113 patients and 43 health workers from seven primary healthcare clinics and a district hospital.

    Some health workers and patients used their own mobile phones for healthcare, bearing the cost themselves, Bring Your Own Device (BYOD) initiatives. Patients used their mobile phones to remind themselves to take medication or attend clinic visits. They appreciated receiving voice call reminders.

    Some patients and health workers accessed websites and used social media to gather health information, but lacked web search strategies. Patients and health workers’ use of websites and social media was intermittent due to affordability constraints for airtime. Many didn’t know what to search for and where to search. 

    Doctors developed their own informal mobile health solutions for their work needs. It also overcomes resource constraints due to rurality. 

    Removing these seemingly unresponsive barriers needs investment in people and infrastructure. It’s a critical component of successful eHealth.


  • eHealth Africa pilots AVADAR to track Toward Polio Eradication progress

    In response to the reported cases of wild poliovirus in Nigeria, eHealth Africa (eHA) partnered with Bill & Melinda Gates Foundation, the  WHO, and Novel-T to pilot a mobile surveillance app for Acute Flaccid Paralysis (AFP) in children. It’s a condition of a rapid onset of weakness of people’s extremities, and includes Guillain-Barré syndrome.  AFP often causes weakness of respiration and swallowing muscles, progressing to maximum severity within one to ten days. 

    WHO defines AFP surveillance as six goals:

    Track wild poliovirus circulationUse data to classify cases as confirmed, polio-compatible or discardedMonitor routine coverage and surveillance performance using standard indicators in all geographical areas and focus efforts in ones that are low-performingMonitor seasonality to determine low season of poliovirus transmissions to help to plan National Immunisation Days (NID)Identify high-risk areas to plan mop-up immunisation campaignsProvide evidence to certification commissions of interruptions of wild poliovirus circulation. 

    Standard indicators are: 

    >90% of expected monthly reports>1/1000,000 annualised non-polio AFP rate per 100,000 children under 15>80% of AFP cases investigated within 48 hours>80% of AFP cases with two adequate stool specimens collected 24-48 hours apart and less than 14 days after onset>80% of specimens arriving at laboratories in good condition>80% of specimens arriving at a WHO-accredited laboratories within three days of despatch>80% of specimens for which laboratories’ results sent within 28 day turn round. 

    AFP surveillance’s one of four cornerstone strategies of polio eradication. The objective’s to identify all cases of polio through a system that targets any case of AFP as a potential case of polio.  AVADAR’s a surveillance tool on android mobile devices provided to health workers and community informants. It aids AFP detection and reporting both in health facilities and local communities.

  • mHealth keeps expanding, but Africa and South America are trailing

    The mHealth market’s been growing steadily, and will keep it up. In its report mHealth App Economics 2017 Current Status and Future Trends in Mobile HealthResearch2Guidance (R2G), a strategy advisory and market research company, assesses how digital intruders are taking over the healthcare market. 

    This year, there are 325,000 health and fitness apps available from all major app stores. It’s 78,000 more than last year.

    Most eHealth practitioners come from Europe, 47%, and 36% from the US, a combined 83%. Asia-Pacific accounts for 11%. South America and Africa trail at 4% and 2% respectively, confirming the need for increased human capacity development.

    Other findings include:

    Android’s overtaking Apple in health app numbers84,000 health app publishers release appsWidening demand and supply gap, with high number of developers and low downloads growth ratesUS$5.4bn investment in eHealth start-ups fuelling the marketUsers will download an estimated 3.6bn apps in 201718% are not developing health apps because of uncertain regulations53% of eHealth practitioners expect health insurances to be  the future distribution channel with best market potentialAn estimated 28% pure eHealth market players in the eHealth industry.

    Two app types may have a big healthcare impact. Artificial Intelligence (AI) is seen as the most disruptive technology.  It’s seen as combining with remote monitoring to be the technologies that will disrupt healthcare most. The profile’s:
