Core Health Data Concepts

Categories of Health Data

Health data comes in various forms, each playing a distinct role in your healthcare journey. For instance, Electronic Health Records (EHRs) provide an all-encompassing view of your medical history, while Electronic Medical Records (EMRs) focus on treatment details within a single healthcare setting.

Here’s a quick breakdown of common health data types:

| Data Type | Description | Primary Use |
| --- | --- | --- |
| <strong>EHRs/EMRs</strong> | Digital records of medical history and treatments | Track medical care and enable provider collaboration |
| <strong>Claims Data</strong> | Records of healthcare services and related costs | Monitor expenses and insurance coverage |
| <strong>Patient Registries</strong> | Condition-specific health information | Track diseases or treatments |
| <strong>Wearable Data</strong> | Metrics collected by devices in real-time | Monitor daily activity and vital signs

Data Collection Methods

Most health data today is gathered through digital tools and wearables. In 2019, 21% of Americans used fitness trackers to monitor their health. These devices collect data in multiple ways. As Dr. Seth Creasy from the University of Colorado School of Medicine points out:

"These devices are super helpful in helping us become more aware of our own health... These are information tools that can help us learn more about ourselves."

Smartphones also play a significant role, using built-in sensors to track activity, location, heart rate, and sleep patterns. While these tools are convenient, protecting the data they collect is just as important.

Data Privacy Basics

Protecting your health data is critical. In 2023, the U.S. Department of Health and Human Services reported 725 major healthcare data breaches - an average of more than two per day.

To keep your health information secure when using fitness apps or devices, follow these tips:

Check privacy policies before purchasing a health tracker.
Enable data encryption wherever possible.
Audit app permissions regularly and remove unnecessary access.
Adjust sharing settings in platforms like Apple Health or Google Fit.

Justin Sherman, a Senior Fellow at Duke Sanford School of Public Policy, highlights the risks:

"We uncovered data brokers selling a range of data about all kinds of mental health conditions dealt with by Americans ranging from depression and anxiety to PTSD, OCD, people battling trauma, and even actually, people who had suffered strokes."

When selecting health tracking tools, choose ones with clear privacy options and the ability to opt out of data sharing. Keep in mind that while HIPAA safeguards traditional medical records, many fitness apps and wearables operate outside these rules.

Data Analytics in Health – From Basics to Business

Reading Your Health Data

This section dives into how to analyze and make sense of your personal health metrics, building on foundational data concepts.

Basic Analysis Methods

Start by looking for daily patterns in your health data. Analyzing these patterns can help you spot trends and make informed lifestyle adjustments. For example, tracking your resting heart rate can reveal important details about your heart health.

A typical resting heart rate ranges between 60–100 beats per minute (bpm), with individuals in better physical shape often showing rates between 50–70 bpm. Research highlights that a 10 bpm increase in resting heart rate is linked to a 9% higher risk of mortality.

To get the most out of your health data:

Wear your tracking device regularly, including while you sleep, to monitor trends over time.
Look for connections between lifestyle changes (like exercise or diet) and your health metrics.

Using visual tools like charts can make it easier to spot patterns and understand your data.

Reading Health Charts

Health apps often include visual tools to make your data easier to understand. For example, the HealthView app, which has a 4.5/5 rating on the App Store, provides customizable widgets to display multiple health metrics at once.

Here are some common health metrics and their target ranges:

| Metric | Healthy Range | Monitoring Frequency |
| --- | --- | --- |
| Steps per Day | 7,500–12,500 | Daily |
| Resting Heart Rate | 50–70 bpm | Continuous |
| Sleep Duration | 7–9 hours | Nightly

These benchmarks can help you work toward better sleep, reduced stress, and improved fitness.

Key Health Numbers

Step counts are a straightforward way to measure physical activity. Here's how to interpret your daily steps:

| Activity Level | Steps per Day | Health Impact |
| --- | --- | --- |
| Sedentary | <

Disrupted sleep patterns can lead to a higher resting heart rate. This ties into a broader trend: the health tracking market is booming, with projections showing growth from $11.5 billion in 2019 to $40.8 billion by 2025. Tracking your health data can help you make small, daily adjustments that lead to better overall wellness.

Using Health Data Day-to-Day

This section explores practical ways to incorporate health data into your daily life.

Sleep Tracking

Sleep tracking tools can help you understand your rest patterns better. For example, the Oura ring, rated 4.6/5 on the App Store, boasts 96% accuracy in tracking sleep metrics. It’s priced at $349, with a $5.99 monthly membership.

Here are a few tips for improving sleep tracking:

Track your sleep regularly to establish patterns and observe how caffeine affects you.
Pay attention to factors like room temperature and light exposure.
Use smart alarms that align with your natural sleep cycles.

"If you're having trouble sleeping, an app can help you track your sleep and identify variables that contribute to better sleep. You might notice you get better quality sleep when you go to bed at a certain time or that diet, caffeine, or alcohol intake impact your sleep quality, and make changes for better sleep."
– Amy Marschall, PsyD

Combine sleep data with other wellness metrics to create a more effective health plan.

Current Limits and Future Changes

Common Data Problems

Nearly half (46%) of healthcare organizations report that data silos present a major challenge. Additionally, poor clinical documentation accounts for 44% of billing errors. These issues often stem from fragmented data systems and the sheer volume of information, which can overwhelm users and hinder effective decision-making.

New technologies are stepping in to address these challenges.

New Health Tech Tools

Despite these hurdles, technology continues to transform how health data is tracked and used. About 25% of Americans now own a wearable device, and this percentage is steadily increasing.

"By combining AI's analytical capabilities with wearable devices' real-time data tracking, we're seeing the beginning of a healthcare evolution that supports healthier, and more connected lives." – TDK

One example of this shift is a digital health program for managing high blood pressure. It enabled 71% of patients to achieve their target blood pressure, compared to only 31% under traditional care methods. These tools not only improve data accuracy but also help tackle the integration challenges many healthcare providers face. Looking ahead, remote monitoring technologies are projected to cut hospital costs by 16% by 2027, potentially saving $200 billion by 2037.

Privacy and Ethics

As health tracking evolves, so do privacy concerns. Healthcare data breaches cost organizations an average of $7.13 million per incident. While HIPAA safeguards traditional medical records, newer technologies bring fresh challenges to individual privacy.

Public trust varies significantly. Only 11% of American adults are comfortable sharing health data with tech companies, whereas 72% trust their physicians with the same information. To address this, it's essential to choose tools that offer HIPAA-compliant encryption, clear user permissions, and transparent policies on data ownership.

Emerging solutions like federated learning models show promise. These models allow for data sharing while still maintaining privacy. However, users should remain cautious and informed about how their health data is collected, stored, and used.

Next Steps with Health Data

Now that we've covered key data concepts and challenges, it's time to focus on practical steps to make the most of your health data.

Key Takeaways

Tracking your health data consistently can lead to better results. Start by focusing on three areas: setting clear goals, choosing the right metrics, and using the right tools. Instead of vague goals like "get healthier", create SMART goals - specific, measurable, achievable, relevant, and time-bound. For example, aim for "walking 30 minutes, five days a week." This structured approach aligns with recommendations from organizations like the AHA and WHO for reducing heart disease risks.
