Summary
A smart medication dispenser, spencer, effectively collects longitudinal patient-reported outcomes, demonstrating good panel persistence and high survey response rates for real-world data generation.
Area of Science:
- Digital Health
- Patient-Reported Outcomes
- Real-World Data
Background:
- The spencer smart medication dispenser collects longitudinal survey data from patients.
- Patients act as a survey panel, reporting on quality of life and outcomes.
Purpose of the Study:
- Evaluate panel persistence and survey response rates for spencer.
- Assess the reliability and validity of spencer-administered surveys.
Main Methods:
- Analyzed data from 4138 polychronic patients using spencer.
- Estimated 2-year panel persistence and 1-year survey response rates.
- Assessed reliability and validity using a fall risk question and associated covariates.
Main Results:
- 2-year dispenser persistence was 51%; 1-year survey enablement was 82.3% with a mean response rate of 84.1%.
- Fall risk measure showed good reliability (Pearson correlation 0.723).
- Fall risk was associated with SSRI/SNRI use, quality of life, and health factors, but not age or sex.
Conclusions:
- spencer generates valuable longitudinal patient-reported outcomes with low attrition.
- The system demonstrates reliability and validity for patient-reported data.
- spencer offers a promising alternative to web-based panels for real-world data collection.

Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

Longitudinal studies are also widely used in other medical and social science fields. For instance, in cardiovascular research, they can monitor patients' health over decades to identify risk factors for heart disease, such as high cholesterol or smoking, and evaluate the long-term effectiveness of preventive measures. Similarly, in mental health studies, researchers might follow individuals from adolescence into adulthood to understand the development and progression of conditions like...

Ideally, the people who observe and record the children’s behavior are unaware of who was assigned to the experimental or control group, in order to control for experimenter bias. Experimenter bias refers to the possibility that a researcher’s expectations might skew the results of the study. Remember, conducting an experiment requires a lot of planning, and the people involved in the research project have a vested interest in supporting their hypotheses. If the observers knew which...

Observational studies are a type of analytical study where researchers observe events without any interventions. In other words, the researcher does not influence the response variable or the experiment's outcome.
There are three types of observational studies – Prospective, retrospective, and cross-sectional.
Prospective Study
Prospective studies, also known as longitudinal or cohort studies, are carried out by collecting future data from groups sharing similar characteristics. One...

Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

Data collection refers to a systematic way of obtaining, observing, measuring, and analyzing accurate information. Observational studies are one of the most widely used methods of data collection. It involves collecting data by observing the behavior and physical characteristics of a sample without making any modifications to the sample.
