Applications of Space Technologies to Global Health: Scoping Review

Background

Space technology has an impact on many domains of activity on earth, including in the field of global health. With the recent adoption of the United Nations’ Sustainable Development Goals that highlight the need for strengthening partnerships in different domains, it is useful to better characterize the relationship between space technology and global health.

Objective

The aim of this study was to identify the applications of space technologies to global health, the key stakeholders in the field, as well as gaps and challenges.

Methods

We used a scoping review methodology, including a literature review and the involvement of stakeholders, via a brief self-administered, open-response questionnaire. A distinct search on several search engines was conducted for each of the four key technological domains that were previously identified by the UN Office for Outer Space Affairs’ Expert Group on Space and Global Health (Domain A: remote sensing; Domain B: global navigation satellite systems; Domain C: satellite communication; and Domain D: human space flight). Themes in which space technologies are of benefit to global health were extracted. Key stakeholders, as well as gaps, challenges, and perspectives were identified.

Results

A total of 222 sources were included for Domain A, 82 sources for Domain B, 144 sources for Domain C, and 31 sources for Domain D. A total of 3 questionnaires out of 16 sent were answered. Global navigation satellite systems and geographic information systems are used for the study and forecasting of communicable and noncommunicable diseases; satellite communication and global navigation satellite systems for disaster response; satellite communication for telemedicine and tele-education; and global navigation satellite systems for autonomy improvement, access to health care, as well as for safe and efficient transportation. Various health research and technologies developed for inhabited space flights have been adapted for terrestrial use.

Conclusions

Although numerous examples of space technology applications to global health exist, improved awareness, training, and collaboration of the research community is needed.

Study of Vehicle Vibration for High-Performance Land Mobile Satellite Tracking System for Telemedicine

The land mobile satellite service (LMSS) is a key component of telemedicine and an important technology for grasping the status of a patient in an ambulance. However, rough road surfaces can destabilize satellite tracking and disturb data communications with the ambulance carrying the patient. Nevertheless, accurate estimates of the location of the vehicle at any given time and rapid reconfiguration of the tracking antenna based on past data can allow stable and effective data communications. This study examined positions characterized by large vibration amplitudes from past data on vehicle vibrations due to rough road surfaces as feature points to provide the vehicle system in advance with reference pitch angle vibration data. Drawing on reference vibration data for convolution and a cost function, The authors synchronized past data with real-time vibration data and accurately estimated the point at which the ambulance or other vehicle passes on the road. They also discuss limits on the range of vibrations that can be used for data synchronization. This study demonstrates that the present method enables high-precision estimates of vehicle location.

The clinical application of mobile technology to disaster medicine

Mobile health care technology (mHealth) has the potential to improve communication and clinical information management in disasters. This study reviews the literature on health care and computing published in the past five years to determine the types and efficacy of mobile applications available to disaster medicine, along with lessons learned. Five types of applications are identified: (1) disaster scene management; (2) remote monitoring of casualties; (3) medical image transmission (teleradiology); (4) decision support applications; and (5) field hospital information technology (IT) systems. Most projects have not yet reached the deployment stage, but evaluation exercises show that mHealth should allow faster processing and transport of patients, improved accuracy of triage and better monitoring of unattended patients at a disaster scene. Deployments of teleradiology and field hospital IT systems to disaster zones suggest that mHealth can improve resource allocation and patient care. The key problems include suitability of equipment for use in disaster zones and providing sufficient training to ensure staff familiarity with complex equipment. Future research should focus on providing unbiased observations of the use of mHealth in disaster medicine.

Initial experience at a university teaching hospital from using telemedicine to promote education through video conferencing

CONTEXT AND OBJECTIVE

Telehealth and telemedicine services are advancing rapidly, with an increasing spectrum of information and communication technologies that can be applied broadly to the population's health, and to medical education. The aim here was to report our institution's experience from 100 videoconferencing meetings between five different countries in the Americas over a one-year period.

DESIGN AND SETTING

Retrospective study at Universidade Estadual de Campinas.

METHODS

Through a Microsoft Excel database, all conferences in all specialties held at our institution from September 2009 to August 2010 were analyzed retrospectively.

RESULTS

A total of 647 students, physicians and professors participated in telemedicine meetings. A monthly mean of 8.3 (± 4.3) teleconferences were held over the analysis period. Excluding holidays and the month of inaugurating the telemedicine theatre, our teleconference rate reached a mean of 10.3 (± 2.7), or two teleconferences a week, on average. Trauma surgery and meetings on patient safety were by far the most common subjects discussed in our teleconference meetings, accounting for 22% and 21% of the total calls.

CONCLUSION

Our experience with telemedicine meetings has increased students' interest; helped our institution to follow and discuss protocols that are already accepted worldwide; and stimulated professors to promote telemedicine-related research in their own specialties and keep up-to-date. These high-technology meetings have shortened distances in our vast country, and to other reference centers abroad. This virtual proximity has enabled discussion of international training with students and residents, to increase their overall knowledge and improve their education within this institution.
