Kaplan-Meier Approach01:24

Kaplan-Meier Approach

719
The Kaplan-Meier estimator is a non-parametric method used to estimate the survival function from time-to-event data. In medical research, it is frequently employed to measure the proportion of patients surviving for a certain period after treatment. This estimator is fundamental in analyzing time-to-event data, making it indispensable in clinical trials, epidemiological studies, and reliability engineering. By estimating survival probabilities, researchers can evaluate treatment effectiveness,...

Central Tendency: Analysis

621
Measures of central tendency are tools used in biostatistics to identify the average or center of a dataset. They offer a single representative value for understanding and summarizing data distribution.
The mean is one such measure, calculated by totaling all values in a dataset and dividing by the number of values. For instance, the mean blood pressure reading (120, 130, 140, 150) would be 135. However, the mean can be affected by extreme values or outliers.
The median, another measure,...

Area of Science:

  • Health Services Research
  • Health Economics
  • Digital Health Marketing

Background:

  • Medicare Advantage (MA) related internet searches have tripled since 2020, with commercial health insurance dominating online information during enrollment periods.
  • Prior research indicates that MA advertising significantly influences enrollment decisions, potentially steering beneficiaries away from traditional Medicare.
  • Understanding the interplay between health plan marketing strategies, consumer search behavior, and enrollment is crucial for informed decision-making.

Purpose of the Study:

  • Validate Google Trends data as a reliable indicator of consumer Medicare Advantage plan selection through seasonality and domain specificity analysis.
  • Quantify the relationship between Medicare Advantage search interest and enrollment data, assessing if search peaks precede enrollment surges.
  • Evaluate local search intensity as a proxy for marketing impact and consumer engagement by aligning search behavior with advertising exposure.

Main Methods:

  • Retrospective analysis of Google Trends data (2004-2024) examining relative search volume and its correlation with Medicare Advantage enrollment.
  • Utilized Centers for Medicare & Medicaid Services (CMS) MA Dashboard for enrollment data and KFF for medical advertising marketing data.
  • Employed novel analysis techniques to assess statistical relationships between marketing, internet searches, and enrollment selection.

Main Results:

  • A significant correlation was observed between Medicare Advantage advertising and related internet searches across US markets, especially preceding and during enrollment periods.
  • Findings suggest a behavioral link between search volume and subsequent enrollment in Medicare Advantage plans.
  • Seasonal trends in searches for MA plans peaked during the annual enrollment period (October-December).

Conclusions:

  • Internet search data provides a valuable, near real-time method for tracking Medicare Advantage search activity geographically and temporally.
  • Repeatable patterns in consumer interest around enrollment periods offer insights into insurance marketing dynamics and choices between MA and traditional Medicare.
  • Enhanced accessibility to Medicare resources and targeted messaging can improve decision-making for Medicare-eligible beneficiaries, particularly underserved populations.
