Symposium Theme

Intensive longitudinal measurement:

Methodologies for collecting, analyzing and interpreting patient-generated data from daily diaries, wearables and sensors

As we collect data more frequently in both clinical and real-world studies, patients are often assessed using intensive longitudinal measurement techniques, such as daily diaries, wearable devices, and/or sensor technology. This allows the recording of data at regular intervals between site visits, the capture of acute events as they occur for clinical monitoring, and/or continuous monitoring in order to answer research questions that were previously unanswerable through traditional data collection.

Despite our ability to collect more data, our knowledge about evaluating new data collection techniques and using these rich data sources effectively is limited.

This symposium will cover

  • patient-centered approaches to endpoint selection/development
  • the subsequent identification of appropriate methods and technology for assessing these endpoints
  • the different ways we currently summarize this data and how this leads to a loss of information
  • ways to maximise our data using improved summary methods and more complex modelling techniques

Attendees will leave this symposium with new insights and better understanding on how to better use, analyze, and interpret intensive longitudinal data generated from daily diary and wearable devices in a more effective and complementary manner.

Sessions

Session I: Intensive longitudinal measurement and you: How do you measure what matters?

Monday, 19 July | 8:10 am – 9:10 am CDT

 

Description:

What does intensive longitudinal measurement mean to you and your research? Daily diary, wearables, and sensors all collect lots of data over a continuous period of time. This is known as intensive longitudinal measurement. When collecting this kind of data, there are additional considerations above and beyond those made when using typical clinical outcome assessment measures. How do you translate the patient experience into selecting the right endpoint and data collection modality, in order to handle the resulting gargantuan quantities of data?

Session II: Walking a mile in the patient’s shoes

Monday, 19 July | 9:25 am – 10:25 am CDT

 

Description:

Have you ever had to have a box constantly strapped to your chest that shows from under your clothes, sleep in a helmet, and answer the same question every day for 365 days? How would that make you feel? How likely would you be to do it? The only way we can understand the patients’ study experience is by engaging them at relevant steps in the research journey. Through understanding the patient experience, we can select more practical measurement tools that can lead to data of better quality, while minimizing patient burden.

Session III: Having your cake and eating it, too: Mixing modalities to enhance interpretation of data

Monday, 19 July | 10:40 am – 11:40 am CDT

 

Description:

So you want to have your cake and eat it, too? Continuous wearable and sensor data is great, but without context it can be difficult to interpret. Diary data provides rich information about how patients feel and perceive their functioning. Together, one provides the broader context to the finer detail of other. However, it is important to carefully consider when it is necessary to collect data from multiple modalities, and when it is sufficient and less burdensome to rely on fewer. Which begs the question, is too much cake bad for you?

Session IV: Why did the researcher throw away their data? - How to handle intensive longitudinal data as a research outcome

Tuesday, 20 July | 8:00 am – 9:15 am CDT

 

Description:

Have you ever felt like you were drowning in data and were tempted to summarise it as an average? The central tendency is not your friend. Reducing data leads to a loss of information and while this can help make data sets manageable, there are techniques available to avoid this. Intensive longitudinal data analysis can maximise the use of your collected data and allows you to answer a range of additional questions. If you’ve got a lot of data, why not try and use it all?

Session V: What makes a step a step? A step by any other algorithm…

Tuesday, 20 July | 9:30 am – 10:45 am CDT

 

Description:

What makes a step a step? Research endpoints need to have meaning and context. Wearables and sensors do not directly count meaningful units such as steps and heart rate. Instead, they measure raw data, such as x-, y-, z- coordinates, or blood volume (photoplethysmography). Before it is ready for our analysis and interpretation, algorithms run complex operations on the raw data to add meaning and context – turning coordinates and blood volume into steps and beats. But…is the definition of a step or a heart beat the same for all patient groups?

Session VI: When good science meets good standards - Regulatory considerations around intensive longitudinal data

Tuesday, 20 July | 11:00 am – 12:00 pm CDT

 

Description:

Are regulatory standards fluid enough to accommodate the evolving landscape of collection and analysis of intensive longitudinal data? Algorithmic interpretation of raw sensor data is a prerequisite for analysis. However, algorithms are typically black boxes, the validity of which is difficult to demonstrate to regulators. Similarly, intensive longitudinal analytical techniques are not commonplace in regulatory decision-making. Such techniques provide powerful ways of understanding patients’ health, but as with emerging technologies, it is as yet unclear what level of evidence is needed to demonstrate this. How do we strike a balance between accommodating evolving techniques and maintaining scientific and safety standards?

Session VII: A World of Pure Imagination: The evolving landscape and undefined future

Tuesday, 20 July | 12:15 pm – 1:15 pm CDT

 

Description:

Throughout the preceding sessions, there have been a lot of questions answered, but many more have been raised. Our panelists will debate whether diaries and sensors are distinct COA measures, or whether they are individual components of a larger assessment of the patient experience that need to be considered together rather than in isolation. In the changing landscape of clinical development, these are important questions that need to be considered to guide where we go next.
