Abstract

WhatsApp as many other Messaging Apps or “Messengers” enables messaging and exchanging documents and/or multimedia element (images, movies, music) through chat like tools; these last characteristics makes WhatsApp useful for the remote-image exchanging in mHealth for teleconsulting. Among the other potentialities of this App there are (I) the possibility to create groups, the so called WhatsApp Groups and (II) the possibility of this App to be installed into a platform based on a personal computer through the version for pc named WhatsApp Web; these potentialities allow both the creation of protected groups for cooperative teleconsulting and the creation of client-server architectures in telemedicine and e-Health. Scholars have recently shown the usefulness of WhatsApp in several mHealth applications. Recent important studies are highlighting, for example, the wide-range opportunities of WhatsApp as an adjunctive tool in mHealth in medical imaging or in specific applications such as in oral medicine in orthopedics and tele-education. In this contribution we share our alignment with these scholars and presents our polarities of research in the use of WhatsApp. These polarities range from the institutional surveillance of the spontaneous phenomena of WhatsApp groups in the families for the monitoring of the fragile patient up to the test of use of WhatsApp in digital-pathology and digital-radiology static imaging and recently in cardiologic dynamic imaging.

Introduction

In a recent scientific contribution Williams and Kovarik respectively from Ministry of Health of Botswana, Gaborone, Botswana and from the Department of Dermatology, Perelman School of Medicine entitled “WhatsApp: An Innovative Tool for Dermatology Care in Limited Resource Settings” (1) faced the overcoming usefulness of WhatsApp in some applications of Medical Imaging such as the Dermatology care opening a scientific interesting discussion.

In particular this contribution:

  1. Firstly, commented the perspectives and the opportunities of WhatsApp highlighted in the Mars and Scott article “Being Spontaneous: The Future of Telehealth Implementation?” published in September 2017 (2) asserting how the faced topic was forward thinking, innovative, realistic, and in alignment with authors’ experience on the ground in Botswana.

  2. Secondly, shared the authors’ position and experience using WhatsApp for dermatology care in Botswana, and explained how this application can be easily adapted and integrated into clinical practice in resource-limited settings to improve patient outcomes.

The opportunities of WhatsApp have been strongly remarked in the two contributions (1,2). Also other recent important studies are highlighting, for example, the wide-range opportunities of WhatsApp as an adjunctive tool in mHealth (3) or in specific applications such as in oral medicine (4) in orthopedics (5) and tele-education (6). Very rare are the cases of experiences don’t creating heath management improvements, as in a case of an application of the management of blood donors (7); furthermore several WhatsApp updates since the 2016/2017 up to now allowed the overcoming most of the few limitations reported by the authors (1).

Purpose of the contribution

The objective of this contribution is to share our alignment with the position of Williams and Kovarik (1) towards the presentation of our research activity moving around WhatsApp at the Istituto Superiore di Sanità (ISS) through several polarities of research. These polarities range from the institutional surveillance of the spontaneous phenomena of WhatsApp groups in the families for the monitoring of the fragile patient up to the test of use of WhatsApp in digital-pathology and digital-radiology static imaging and recently in cardiologic dynamic imaging.

WhatsApp in mHealth: the potentialities

Messaging Apps or “Messengers” are Apps and platforms that enable messaging and exchanging documents and/or multimedia element (images, movies, music) through chat like tools. The alternatives are many and among the most known we find: Hangouts; Telegram; Whatsapp; Facebook Messenger; Viber; Skype; Tango; OoVoo; Snapchat; WeChat; Yahoo Messenger. Not all, however, have the same success. WhatsApp (Facebook Corp, USA) instant messenger is one of the most diffused ones and allows the quickly sending messages on your mobile phone to any contact on your contacts list in the phone. Obviously the only requirement is that people involved in the network must have the APP installed on their own device. Currently, WhatsApp is compatible with just about all mobile operating systems on the market: Android, iOS, Symbian and Windows Phone. This basically means you are able to use WhatsApp to communicate with anyone, regardless of what model of device they have. WhatsApp users can send text messages, voice messages, links multimedia-files (images, movies, music) to any other user; these last characteristics makes WhatsApp useful for the remote-image exchanging in mHealth for teleconsulting. Among the other potentialities of this App there are (I) the possibility to create groups, the so called WhatsApp Groups (WAGs), and (II) the possibility of this App to be installed into a platform based on a personal computer through the version for pc named WhatsApp Web; these potentialities allow both the creation of protected groups for cooperative teleconsulting and the creation of client-server architectures in telemedicine and e-Health. The opportunities of WhatsApp have been strongly remarked in in the previously cited contributions (1-6).

WhatsApp in mHealth: the position and the study at the ISS

We: (I) found the Williams and Kovarik contribution (1) current, interesting and timely to open a debate among the mHealth scholars and stake-holders especially, considering also that it is a position paper from a governmental institution (the Ministry of Health of Botswana); (II) are certainly also aligned with the same position of William and Kovarik. Our specific position of alignment with (1) in regards to the opportunities of WhatsApp comes directly from our governmental experience at the ISS (The Italian NIH) in the Centre of innovative technologies in public health. This experience is directed into two directions both with an institutional and a research point of view.

The first direction is to face, with a careful consideration as an active observer, the emerging experiences of the use of WhatsApp as a spontaneous tool in familiar mobile-networks dedicated to the management and monitoring of fragile subjects in domiciliary care. Here WhatsApp is used as a means to H24 connect in specific WAGs (Figure 1) the familiars, the familiar care-givers, the non-familiar care-givers (as for example the salaried ones), other health care (HC) actors (as for example the Italian family doctor). This was recorded in recent conferences at the ISS dedicated to the technological innovations in the monitoring of the fragility (8); the role of the ISS is clearly to monitor with attention as active observer these experiences also in consideration of the regulations (9,10).

The second direction is focused to the application of WhatsApp in the medical-images exchanges. In particular the two field of interest which are receiving special attention are:

  • ❖ The digital pathology (DP), with the two components, digital cytology and digital histology, in consideration to the diffusion of these technologies from PC-based application (11) to the mobile-health applications (12,13).

  • ❖ The digital radiology (DR), embedding all the DICOM compliant (14) diagnostic systems.

We have designed specific studies with working groups (WGs) comprehending all the actors on the use of WhatsApp in these fields. Both in DP and in DR we are assisting to positive feedback from actors in the WGs, as highlighted on the specific assessment by means of dedicated surveys in DP (15) and in DR (16,17). Figure 2 shows some steps of application of WhatsApp in the critical sector of DP represented by the digital cytology (18).

In DR, where the use of PACS (16,17) is well ruled and standardized, it was found particularly useful the potentiality of WhatsApp Web (Figure 3) as a means to be installed in the server (i.e., the platform with the PACS) to send images from here to the remote teleconsulting sites.

Work in progress at the ISS: WhatsApp and the dynamic images

The next step will be focused to:

  1. The specific design and application of technology assessment (19,20) in these fields of DR and DP of mHealth, also using the TAM models (21). At the moment we are completing some of these studies, widening of the cited studies (15-17) and proceeding into the dissemination.

  2. The broadening of the studies in the field of dynamic images in DR. In the diagnosis in this field it plays an important role the visualization of the image kinematics, while the image resolution is still important but less critical. In particular we have focused to the hemodynamics and echocardiography. A first problem that we had to solve was the integration of such images into WhatsApp Web; in fact the PACS are able to provide files converted from DICOM into AVI format; but this format is not compatible with WhatsApp Web which accepts only specific versions of MP4. The “egg of Columbus” was represented by the decision to not convert the AVI into an MP4 file; but to store the AVI directly into a cloud and to export the link pointing to the file. This avoided complex conversions by simply exchanging the internet link using WhatsApp but without using its “attachment functions”.

The reader can open by herself or himself these two links relate to one hemodynamic study and to one echocardiographic study and copy them into WhatsApp to try:

In alternative Figure 4 shows the 2 QR codes, useful to extract the links by smartphone. Figure 5 shows two snapshots from smartphone of the two studies. Surely also these studies will follow a road map comprehending the technology assessment and the use of a TAM model (19-21), as for the static images in (1).
