A First Look at VascTrac PAD Research Study
Millions of Americans over the age of 50 suffer from peripheral artery disease (PAD), a lifestyle-limiting vascular condition that hampers blood flow to the legs. PAD restricts a patient’s ability to walk for continuous distances without experiencing pain, a severe impediment to patient mobility- this symptom is called claudication. What is more, the disease is often coupled with parallel vascular disease in the heart and brain, putting the patient at risk for heart attack or stroke.
Treatments for PAD such as angioplasty and stenting often have short-lived effects, and symptoms return as the blood vessels narrow once again from healing or scarring.
There are 525,600 minutes in a year, but we only monitor 90 of them. Optimal PAD surveillance is limited by the very structure of physicians’ typical data collection techniques. Patient visits occur periodically with months of unmonitored activity in between; this leaves a “black hole” of unused information that could otherwise be used to detect signs of decline or to find overlooked specificities of a disease.
Enter VascTrac, the first mobile health tracker app for PAD, developed using Apple’s ResearchKit framework. ResearchKit modules were used to provide VascTrac’s clinical-grade consent, enrollment, and survey functionality for patients across the nation. Using the iPhone’s HealthKit Activity Tracker and Core Motion framework, we gather passive data about total number of steps taken, flights of stairs climbed, and daily distances covered from consenting participants. In particular, the VascTrac app measures the “maximum steps without stopping” (MSWS), which we believe is the most sensitive and specific metric for PAD patients. Patients with claudication typically have to stop for over a minute to let their leg muscles recover. Interested patients simply download the app, consent to participation, and continue their daily activities. They also perform 6-minute continuous “walk tests” at two week intervals and fill out a survey about symptoms and recent procedures every quarter. All information is gathered, de-identified, and encrypted for security purposes in compliance with HIPAA.
VascTrac aims to validate passive activity tracking from a smart phone as a mode of surveillance for disease burden in patients with PAD. Especially after surgical procedures, VascTrac will explore new paradigms for personalized surveillance to predict and prevent treatment failures- a new form of Precision Medicine. We plan to grow with new technology, providing ever-improving tools to help patients move forward, pain-free.

Phendo is a new mobile app designed by Columbia University’s Citizen Endo project using Apple’s ResearchKit. The aim of the Phendo study is to bridge the gap between patient experience of endometriosis and clinical understanding of the disease.
Phendo is differentiated from other ResearchKit apps by capturing variables of a disease that is not well understood and for which phenotypes are still unclear. The research team employed iterative participatory design, engaging patients in building a meaningful tool for self tracking using both moment- and day-level surveys to document living with endometriosis. The app was developed by Applied Informatics.
A challenge arose in the need to achieve both individual self-tracking and yet obtain population-level signals. To meet both research and user needs and the unknown nature of endometriosis, Applied Informatics created custom profile questions and a multi-select image choice question for survey answers to capture detailed demographic and disease specific information from participants.Custom Profile Responses Feature
Custom profile questions give participants the ability to personalize responses to track specific medications and foods and exercises that impact endometriosis symptoms. A ResearchKit extension was developed (via ORKStepViewController, code example here) that allows any type of profile question response to be entered, processed through an API and then displayed back to the participant as selectable survey responses.Multi-Select Image Choice Question
Phendo’s multi-select image choice question is an upgraded version of the ORKImageChoiceAnswerFormat class that added two features. First, image choices no longer scale down and shrink when there are too many options to display in the view and instead allow scrolling horizontally. The second feature added allowed for multiple image choices to be selectable rather than allowing only a single option.
The multi-select is implemented using the following ORKImageChoiceAnswerFormat construct (code here) and is currently planned for contribution back into the ResearchKit framework.

Sage Bionetworks is a non-profit research organization dedicated to accelerating the pace of biomedical research. It is our perspective that innovation and life saving advances have been hamstrung by lack of access to research data. We feel that research participants, as data donors, are the ones who should own and control if and how their data is shared.
However, data sharing is causing considerable conversation across the biomedical research community. Researchers are rarely professionally recognized or compensated for sharing data. However, when funders provide incentives we have found that many scientists are up for the challenge. As such, we have created a data sharing path rooted in practical application which we hope will be useful for other ResearchKit studies.
In March 2015, we launched the mPower Parkinson Study: an observational study designed to remotely quantify daily changes in symptoms of Parkinson Disease (PD). During the first six months of mPower 12,201 participants completed the consent and enrollment process, a scale never before seen in PD research. 9,520 (78%) participants opted to share their data broadly with qualified researchers, including over 1,000 who self-reported a Parkinson diagnosis. Earlier this year, we made the data available worldwide, and published an article in Nature Scientific Data describing the study’s methodology and data in detail.
Since the data release, more than 50 researchers from 14 countries and 5 continents have requested and been granted access to the mPower data. These researchers are the first of a growing community collectively contributing to our understanding of how PD symptoms can be remotely tracked and managed over time. We hope that researchers will rise to match the generosity of the study participants who have shared their data by joining forces to accelerate the insights gleaned from these data.

PPD ACT was designed by UNC Chapel Hill researchers in partnership with the PACT Consortium to understand more about the genetic basis of postpartum depression (PPD) and postpartum psychosis (PPP)—devastating disorders that impact 1 in 8 women who give birth. Our goal is to learn about the reasons why some women get PPD or PPP and other women do not. The successful launch of the PPD ACT app in March, 2016 was a result of strong social media campaigns, including outreach by Postpartum Progress, as well as traditional media coverage (New York Times, CNN). Almost 11,000 women have enrolled in the iPhone-based research study, far surpassing expectations.
Of those who have enrolled, 5,306 women met criteria for postpartum depression and have been sent a saliva DNA sampling kit (provided free by NIMH). Approximately 3,000 women have already returned their spit kits to the NIMH DNA biobank—some with notes of thanks for conducting this research and having the opportunity to participate in a study that could help prevent suffering in the future.
We know that many women have sought care after the PPD ACT app told them of the severity of their PPD symptoms. This has been a wonderful use of the PPD ACT app as a screening tool that has received widespread support from clinicians and advocacy groups across the U.S.
Based on the feedback we have received, it is clear that app-based technology is an effective way to engage women in research during the perinatal period. We believe that PPD ACT offers the ability to reach women and provide vital education and resources, in addition to study participation in ways that have not previously been possible. PPD ACT is currently available in the U.S and Australia, but is coming soon to the U.K. and Canada.

REDCap is a popular web application built to support the data capture and management needs for biomedical clinical and translational research. With the goal of bringing ResearchKit within reach of all investigators regardless of budget and access to developers, I created status/post, an iOS- and supporting web-application that integrates REDCap and ResearchKit for rapid production and deployment of powerful iPhone and iPad apps for medical research.
Researchers can now connect ResearchKit to REDCap’s API to take advantage of its capabilities in native applications, allowing them the further advantage of the iOS SDK, for example, implementation of Active Tasks. REDCap can also serve as the required HIPPA-compliant data management solution for storage and analysis of collected data. Perhaps most exciting, investigators can use the REDCap interface that they are already familiar with to design a complete ResearchKit-based application without the need for developer resources.
Since announcing the application at Washington University in St. Louis in November 2015, I have partnered with researchers on over fifteen projects. With each project, exciting new features such as geofencing, iBeacon ranging, HealthKit integration, kiosk mode, real-time monitoring and analytics, 23andMe integration, and customized messaging have been added and are available to all future projects.
ResearchKit and REDCap are force multipliers, greatly expanding what is possible for me as a developer, and for my research partners. They are natural companions, and building bridges between them continues to be rewarding and fun. I am looking forward to the discoveries this integration will help uncover.

Today we released ResearchKit 1.4 which provides several new updates and features that will add enhanced functionality to your ResearchKit apps.
A new video capture step allows for study participants to submit video responses to surveys and tasks which can provide critical information otherwise lost in a still image. Additionally, we added a review step for users to quickly look back at and revise their survey answers.
To address the concerns of researchers and participants who have difficultly locating an unobstructed path for 20 steps, ResearchKit 1.4 introduces the “walk back and forth” activity task. To perform this task, users are instructed to walk and turn in a full circle, allowing the tests to be conducted in smaller spaces.
More features to be excited about:
- Signature Step: Now supports the Apple Pencil and can be added to any task workflow.
- Voice Task 2.0: Voice task has been updated to account for ambient noises and is now able to advise users to relocate to a quieter area if necessary.
- Hand Tremor Activity Task: Allows researchers to collect accelerometer and motion data while asking the participant to hold the device in their most affected hand.
- Data Collection Module: This new module makes it even easier to aggregate data from HealthKit & related device sensors.
- Tapping Test: New update includes the tapping duration as a part of the result.
We can't wait for you to download the new release and take advantage of all the new improvements!

Vital signs are indicators of general physical health status. Body temperature, heart rate, blood pressure, breathing rate, and pain are easily assessed and used to detect medical problems and show progress toward recovery. Walking speed has also been shown to be an important vital sign; however, uptake in healthcare is slow and there isn’t an easy way for the general population to measure it. The Duke Clinical Research Institute has launched the 6th Vital Sign study, designed using Researchkit, to establish walking speed as a new standard for measuring physical health on iPhone easily, anywhere, and by anyone.
Participation is simple. After consenting to the study, users provide basic demographics, complete a two minute walk test using built-in iPhone sensors to monitor stride, and are asked to answer general health questions. Those with an account have a dashboard to track performance, which can be especially useful during recovery from illness or injury. Users receive feedback on their walking speed compared to published norms for their age and sex. Performance reports can be shared as PDFs with others including healthcare providers. The study will help our team validate walking speeds of 0.6 m/s or slower as an indicator of poor health, hospitalization, and dependence for all adults, as has been shown for older adults.
Multiple users can participate with their own account on a single device. This was designed to engage non-iPhone users and people of all ages. It also allows entire households, nursing homes and communities to assess walking speed on a single iPhone. We hope this helps create an “off the shelf” smartphone-based approach for the general public to measure and monitor walking speed.
It took decades to establish blood pressure as a vital sign and efforts continue today to increase screening and detection of hypertension. Our hope is that technology will accelerate adoption. Please join us to create a new marker of health establishing walking speed as the sixth vital sign.

Chronic inflammation caused by Rheumatoid Arthritis (RA), characterized by severe joints pain and swelling, often leads to irreversible joint deformities and physical disability in patients. Wrist function is critically important to our daily lives. Without it, simple tasks like writing, opening a door, brushing teeth, eating, getting dressed, etc. become extremely difficult.
The wrist’s normal range of flexo-extension movement drastically reduces over time in patients affected by RA. There is no tool to objectively assess wrist joint function in a quantifiable manner. We developed a wrist exercise for the GSK PARADE Study using a custom ResearchKit active task. During the exercise, ResearchKit collects motion data from the accelerometer, magnetometer and the gyroscope sensors in the device in order to measure the forward and backward bending of each wrist. After the exercise, the data recorded by ResearchKit is packaged and sent to the secure back-end for assessment by the study scientists. A secondary custom feature built into the wrist exercise is an ability check. If the users indicate they cannot perform the exercise, they are automatically opted out.
The mobility data gathered via the wrist exercise could potentially represent an objective tool to investigate joint function compared to traditional methods. The wrist exercise may also predict functions that are important to one’s ability for independent living. Outputs from the app will be correlated to the patient’s medical history, medications and other symptom scores to achieve a holistic view of the patient’s RA symptoms.
This is our first attempt to develop novel assessment tools from data collected in the PARADE study, but we believe ResearchKit has the potential for industry-wide standardization and re-usability, which is why we chose this open-source platform . We will learn from it and hope to disrupt the model for how we conduct research in the future and ultimately improve patient health.

Today the Mood Challenge for ResearchKit announced five semi-finalists. The Challenge, a New Venture Fund program funded by the Robert Wood Johnson Foundation and powered by Luminary Labs, launched in April and sought proposals for ResearchKit studies that will further our understanding of mood and how it relates to our daily lives, health, and well-being. Each semi-finalist has proposed innovative new ways to use sensors in iPhone to help researchers gather data more frequently and more accurately from participants using iPhone apps.
The five ambitious proposals aim to bring fresh insights and capabilities around mood, biology, and social context to both researchers and users with new methods for mental health diagnostics, clinical care delivery, daily wellness tracking, and behavioral interventions. They will launch longitudinal studies to study correlations between mood and contextual factors, gather insights and data on daily habits and self-reported mood and test the effectiveness of novel behavioral interventions, to innovate the practice of mental health care delivery and use sensors to demonstrate biological links between mood and health. With studies ranging from new diagnostics for bipolar disorder, to the biomarkers of stressed caregivers, to measuring symptoms in trauma survivors, the semi-finalists each aim to bring new ResearchKit capabilities to the mental health research and clinical community.
Following review by an expert Review Panel, the Mood Challenge semi-finalists were selected by an esteemed panel of judges with expertise across psychology, health, and technology.Each semi-finalist will receive $20,000 and enter the Virtual Accelerator, which includes an in-person Boot Camp to develop their proposals into designs with support from experts in research, app design, and ResearchKit. In October, two finalists will be selected to receive $100,000 and develop their designs into prototypes that will be piloted with iPhone users.
Meet the semi-finalists:
The Aware Study will measure mood and posttraumatic stress symptoms among the millions of adults living with PTSD. The study will develop and validate mobile methods, including passive data collection, active tasks, and linguistic analysis, while exploring how social and contextual factors such as connectedness and activity levels can be used to rapidly detect changes in posttraumatic stress symptoms.
BiAffect is a system for understanding mood and neurocognitive functioning in bipolar disorder using keystroke dynamics, such as typing speed and errors, to track and predict mood episodes. Alteration in communication is one of the main, problematic symptoms of bipolar disorder. This study will unobtrusively monitor non-verbal speech/behaviors to improve our understanding of mood disorders and provide a means of predicting future mood fluctuations.
Mood Circle will improve on mood detection and modeling using passive data tracking and self-reports on mood by incorporating social networking. Users of Mood Circle will enlist their closest companions to track their mood and contribute data to this shared platform, improving the experience and data models for each user while investigating social influences on mood and behavior.
MoodSync will identify how daily mood and social environments are associated with biological aging among family caregivers. This population is at high risk for mental and physical health problems caused by chronic emotional distress. By triangulating assessments of social interactions, mood and affect, and cell aging via saliva collections, MoodSync will improve our understanding of how caregivers can thrive under chronic stress.
Mood Toolkit will provide mental health researchers with a configurable toolkit to study daily emotional health and wellbeing through the ResearchKit framework. The study will combine biometric data from external sensors such as heart rate monitors, with user surveys and machine learning to generate and validate personalized insights and interventions to improve emotional health.
Stay tuned for the finalist announcement in October!

47 million people worldwide live with dementia. Alzheimer's disease is the most common form of dementia, and causes difficulties in memory, attention, and high-level thinking. Although drugs have shown some effectiveness in mediating dementia symptoms their impact has unfortunately been limited. Many studies have shown that physical activity, diet, and social engagement all influence both age-related cognitive decline and the symptoms of dementia, suggesting that factors directly under our control may be the best way to influence cognitive health. However, we don't know exactly how these factors interact within an individual to affect cognition and overall quality of life.
The Mindshare studies are designed to directly involve patients and their caregivers in the research process to assess how these factors interact to affect both normal (age-related) and pathologic (dementia-related) cognitive decline. We used the ResearchKit open source platform and integrated our validated cognitive tests with both subjective (questionnaire based) and objective (activity tracking, HealthKit, GPS) measures of behavior, physical activity, and life space.
Since our participants include seniors, we felt it was important to provide an iPad version of the application to support larger font and interface components. The iPad version also allows multiple family member participation, with multiple users being able to securely login and participate using a single device. As ResearchKit studies transition into clinical settings, we anticipate that this type of multi-user application support will become more broadly used.
To recruit participants, we used IRB reviewed Facebook advertisements to specify ad placement based on location, demographics, devices, and operating systems. We are also able to target participants based on unique interests, allowing us to reach over 30 million people interested in Alzheimer’s disease, caregiving, and dementia. An exciting aspect of mobile ad based recruitment has been obtaining near real-time measures of reach and engagement, providing an effective, direct response mechanism for the success of study recruitment.
We're excited that our approach has the opportunity to streamline large-scale neuroscience studies and enhance our ability to discover new relationships between cognition, lifestyle, and health.

Behavioral economics, positive psychology, organizational behavior, econometrics… what do all of these fields have in common? A focus on the impact of mood on outcomes and behavior.
For too long, mood has been a largely subjective and often ill-defined target of study. Linked to a wide range of environmental factors and social determinants – such as pollution, sleep, social connectedness, and access to food – mood is the subjective, free-floating extension of our emotional experience. We know that mood is one of the keys to health; whether you are happy, depressed, stressed out, anxious – all impact your physical wellbeing. However, our knowledge of the relationship between mood and social, environmental, and economic factors remains limited, despite decades of study.
While many previous ResearchKit studies have focused on improving the patient experience for specific ailments and disorders, the recently launched Mood Challenge for ResearchKit, a New Venture Fund program funded by the Robert Wood Johnson Foundation, seeks to bring new insights and capabilities around psychological health and happiness to everyone with an iPhone.
Apps exist to help track mood, and there are clinical assessments used to measure it, but never before has there been an opportunity to combine self-reporting with background data analysis across thousands of subjects to paint a more nuanced picture of mood. The ResearchKit platform combines the standardization and reliability needed for scientific viability with the accessibility of a frictionless tool already in your pocket.
Beyond quantifying correlations between mood and social context, and translating analog clinical assessments into frictionless digital tools, we believe the most exciting aspect of the Mood Challenge will emerge from unmeasured and yet unimagined analyses. The most intriguing and successful studies will develop active and passive tasks that combine disparate data streams and user input to answer questions about what our phones know about our mood and mental wellbeing. The fact that these questions are yet unanswered (and, in many cases, unasked) is what makes ResearchKit – and the Mood Challenge – so exciting.
The Challenge will award $500,000 in prize money as well as expert mentorship and opportunities to pilot new studies. To learn more about and to submit a proposal, visit: www.moodchallenge.com.

This week 23andMe introduced a module that allows researchers to seamlessly integrate genetics into their ResearchKit apps. The module and its documentation are available on GitHub.
"This new technology gives researchers a turnkey way to integrate genetics into their studies," said Anne Wojcicki, 23andMe CEO and co-founder. "This will enable research on a much broader scale. Incorporating genetics into a platform with the reach of ResearchKit will accelerate insights into illness and disease even further."
The 23andMe module will allow interested researchers who are using the ResearchKit platform to support the collection of genetic data for their studies from current 23andMe customers and beyond. Using the module, researchers can allow existing 23andMe customers to easily contribute their data to a study. Or, researchers could choose to offer genotyping services to their study participants through 23andMe, with the services being funded by the researchers. Participants will then have access to the full 23andMe service, and researchers will have a simple, low cost way to incorporate genetic data into their studies.
Once a participant agrees to share their genetic data with a study, the researcher can then use the credentials they receive from the module to access the participant's genetic data via the 23andMe API.
Data sharing within the context of the ResearchKit module has been structured to provide the same robust privacy protections as all 23andMe research. 23andMe only allows a researcher to access data when the user explicitly agrees to share that data with the researcher by providing informed consent, and the participant can disconnect from an app in their 23andMe settings anytime to prevent any future information sharing. The information 23andMe shares on our customer's behalf with third party research apps is de-identified and encrypted, safeguarding the data during transfer.
We also require that any partner using the 23andMe ResearchKit module have their study approved by an Institutional Review Board, which is an independent panel of experts which ensures that all research is conducted in accordance with all federal, institutional and ethical guidelines.
23andMe has created a development environment for researchers looking to include the 23andMe module in their app. Send an email to GeneticsModule@23andme.com for more information on accessing the development environment.
If your app will only accept data from existing 23andMe customers, then you may not need access to the development environment. You can create a development API account here.
