In the US, use of the Mitra device is limited to research and non-diagnostic applications. In many countries outside the US, the Mitra device can be used as a sample collection device for clinical diagnostic applications, as referenced in some content.

pediatric research can be done remotely

by Neoteryx | 4 min read

Research scientists and clinical trial managers can take advantage of the technologies that doctors are using in telemedicine to access patients at home. Shipping remote specimen collection kits out to study subjects at home, and connecting with them through telephone calls, video chats, digital enrollment portals, and online updates, will help your remote studies and virtual trials succeed. The remote approach can work particularly well for pediatric studies, where parents prefer the convenience of enrolling their children in research that allows them to stay safe at home as much as possible.

The Pandemic Proved That Remote Studies Work

The COVID-19 Pandemic and associated lockdowns forced the science and medical communities to pivot to remote models. Thanks to the Internet and other technologies available today, this remote approach was largely successful. Instead of asking their patients and study subjects to travel to and from the clinic or trial site for their lab tests and follow-up appointments, providers sent the “lab” to them.

Practitioners monitoring post-transplant kids collected the necessary blood samples from them by mailing specimen collection kits out to their homes. Family members used the provided instructions & video demos to assist their children in collecting their own specimen samples. Once collected, samples were safely sealed into specimen bags and special envelopes for mailing to the designated lab for analysis. This remote approach produced reliable data that researchers and practitioners used to make critical decisions. Referencing that data, providers also conducted follow-up appointments via video, email and phone.

Researchers and physicians working with pediatric populations across great distances can use an array of remote technologies to share documents and communicate in real time with colleagues, study participants or patients, while also accessing important data. Now doctors in Mozambique can reach out to their colleagues in Chicago and discuss cases. Telehealth technologies, when paired with remote specimen collection, allow them to monitor individuals, discuss lab and serology reports, adjust dosing in medication, and more. They can evaluate sick children at a remote school or a distant clinic or gather specimen samples at a field site in an underdeveloped country.

In conjunction with increasingly sophisticated telemedicine approaches, remote pediatric blood collection is helping to make research and healthcare available to more people around the globe. Microsampling technology that is based on dried specimen collection versus liquid sample collection is easier in remote areas because no refrigeration or freezer transport and storage are necessary. For example, very small samples of blood can be collected from a quick and easy fingerstick using a portable Mitra® device. A precise volume of blood is rapidly absorbed on the device’s VAMS® tip. This sample will dry on the tip during shipment via regular post. Unlike the sample contamination risks posed by dried blood spot (DBS) cards during shipment, Mitra microsamples are protected within the device’s plastic outer cartridge.

With portable and easy-to-use Mitra devices, no professional phlebotomist is required to conduct a venipuncture blood draw to collect wet blood samples in tubes. By following simple instructions, research personnel or study subjects can easily collect Mitra samples at home or in low-resource locations for low-cost mailing to a central lab.

The fingerstick microsampling technique is also much less stressful for children, especially if it can be performed in the comfort of home or other familiar surroundings with a parent or other family member to help.

Remote technologies and remote specimen collection using dried samples can be applied in many situations and environments:

  • Management of chronic medical and medical problems. After an initial in-clinic evaluation and training/orientation on how to perform fingerstick sampling, study subjects or patients can self-collect samples at home and use telemedicine technology to follow-up with their research trial coordinator or doctor.

  • Peer-to-peer consultations. The attending physician can confer with research experts and medical peers around the world for help with cases or special public health programs.

  • Education. Researchers, lab technicians and doctors can attend webinars virtually without the expense of travel, to learn how to apply remote sampling & remote monitoring using the latest technologies.

  • Therapeutic drug monitoring / patient monitoring. The physician can "see" his or her patients at times when they are unable to come to hospital or the clinic office. Specimen samples can be mailed directly from home to lab, where samples are analyzed, and bloodwork data can be uploaded online for access by the physician or clinical trial manager.

  • Research. Remote technologies have had a positive impact on medical research, helping to minimize disruptions to important studies caused by geographical distances or lockdowns during pandemics. Specimen collection kits can be shipped out to people at home, and research subjects can be reached a city or county away from the research center, greatly increasing the number and diversity of people available for studies.

  • Personalized medicine, self-care & compliance. Remote technologies put patients, study subjects and their families in control, giving them more agency in managing their care. Research subjects often express a preference for self-collecting their own specimen samples at home and mailing them to the lab, rather than visiting the study site. The comfort and convenience of at-home specimen collection and telehealth communications with the staff also eliminates the need for taking time away from work or school for a day of travel. Since remote studies require less time commitment, more people are likely to enroll in studies they might otherwise skip. Professional personnel and parents report that children are less anxious or fearful of fingerstick microsampling at home, which is a much gentler approach compared to the traditional needle-poke in the arm vein for a blood draw at the lab or clinic.
Home sampling & tele-communications are reinventing pediatric research and medicine.
