CPR Preparedness Across Massachusetts Public High Schools: A Statewide Cross-Sectional Study

This statewide cross-sectional study of Massachusetts public high schools reveals that while most institutions offer some CPR instruction, student training coverage remains limited and is significantly lower in Title I schools, highlighting a critical need for equitable policies to improve cardiac emergency preparedness.

The Gist

Imagine a massive school bus system across the state of Massachusetts. On this bus, there are 413 stops (the public high schools). The researchers wanted to know: If a heart stops beating on this bus, do the students and teachers know how to jump-start it?

Here is the story of their investigation, told simply.

The Big Picture: Why This Matters

Every year, hundreds of thousands of people in the US have their hearts stop outside of a hospital. The only thing that keeps them alive until an ambulance arrives is a person nearby performing CPR (chest compressions).

Schools are a perfect place to teach this skill. Almost every teenager goes to high school. If you teach a kid CPR in school, they grow up to be an adult who can save a life in their neighborhood, at work, or at home. It's like training a whole generation of "superheroes" before they even leave the building.

However, Massachusetts doesn't require schools to teach this. So, the researchers asked: Are our schools actually doing it, and is it fair?

The Investigation: A Statewide Check-Up

The researchers sent a digital "report card" to all 413 public high schools in Massachusetts. They asked simple questions:

• Do you have CPR training?
• Do you have the fake chests (manikins) to practice on?
• Do you have defibrillators (AEDs)—those machines that shock the heart back to rhythm?
• How many students and teachers actually know how to do it?

The Response: Only about 1 out of every 4 schools (24%) filled out the report card. While this isn't a perfect snapshot of every school, it gives us a very strong clue about what's happening.

The Findings: The Good, The Bad, and The Unequal

1. The "We Have a Class" vs. "Everyone Learned It" Gap
Most schools (72%) said, "Yes, we offer CPR classes."

• The Analogy: Imagine a school says, "We have a swimming pool." That's great! But if only 10% of the students actually know how to swim, the pool isn't doing its job.
• The Reality: In these schools, while classes exist, very few schools actually trained all their students. Only 10% of schools said they had trained 100% of their students. Most schools had only trained a small slice of their student body.

2. The Great Divide: Rich vs. Poor Schools
This is the most important part of the study. The researchers split the schools into two groups:

• Title I Schools: Schools with many students from lower-income families.
• Non-Title I Schools: Schools with fewer students from low-income families.

The Result: The schools with more money trained four times more students than the schools with less money.

• The Analogy: Imagine two fire stations. Both have fire trucks (AEDs) and hoses (manikins). But in the poorer neighborhood, the fire station only teaches 1 out of 10 people how to use the hose. In the wealthier neighborhood, they teach 4 out of 10.
• The Shock: Even though the poorer schools had just as many machines and equipment as the richer schools, the students in the poorer schools weren't getting the training. It's like having a library full of books but no one in the poor neighborhood is allowed to check them out.

3. The Geography Game
The study also looked at different counties (regions). Some areas were doing a fantastic job, while others were struggling. It was a bit like a patchwork quilt where some squares were bright and colorful (lots of training) and others were dull and gray (very little training).

Why Does This Matter?

If a heart stops in a wealthy neighborhood, there's a better chance a bystander knows CPR. If it stops in a poorer neighborhood, that chance drops. This creates a "survival gap" based on zip code and income.

The study suggests that schools are missing a huge opportunity to fix this. By not training everyone, they are accidentally leaving the most vulnerable communities without a safety net.

What Should We Do?

The authors suggest a few simple fixes:

1. Make it Mandatory: Just like you can't graduate without math or history, maybe you shouldn't be able to graduate without knowing CPR.
2. Targeted Help: Give extra money and support specifically to the schools that are struggling (the Title I schools) to help them get their students trained.
3. Use What We Have: There are already programs and grants available (like the American Heart Association's help) that schools could use to buy equipment and run training days.

The Bottom Line

Massachusetts schools are holding the keys to a life-saving skill, but they aren't handing the keys to everyone equally. The equipment is there, but the training isn't reaching the students who need it most. To save more lives, we need to make sure every student, regardless of their background, leaves high school knowing how to restart a heart.

Technical Summary

1. Problem Statement

Out-of-hospital cardiac arrest (OHCA) causes over 350,000 deaths annually in the US, with survival heavily dependent on early bystander cardiopulmonary resuscitation (CPR). While schools are frequent sites of cardiac events, Massachusetts lacks a statewide mandate for CPR graduation requirements, and data regarding school-level preparedness is scarce. Furthermore, existing literature suggests that schools in lower-income communities face greater barriers to acquiring CPR equipment and training resources, potentially exacerbating health inequities. The study aims to evaluate the current state of CPR and Automated External Defibrillator (AED) infrastructure in Massachusetts public high schools, specifically examining disparities based on socioeconomic status (Title I status) and geography.

2. Methodology

• Study Design: Observational, cross-sectional study using an electronic survey.
• Population: All 413 public high schools in Massachusetts (including charter, vocational, and technical schools) serving grades 9–12.
• Data Collection Period: September 29 to November 17, 2025.
• Instrument: A 14-item survey administered to school personnel with direct knowledge of emergency preparedness (e.g., nurses, principals, athletic directors).
  • Data Points Collected: Enrollment, staff size, number of AEDs and CPR manikins, counts of trained students/staff, existence of CPR instruction, and Cardiac Emergency Response Plans (CERP).
  • Exclusion: The CERP item was excluded from analysis due to respondents conflating it with the state-mandated Medical and Behavioral Health Emergency Response Plan (MBHERP).
• Response Rate: 100 schools responded (24.2%), representing 13 of 14 counties.
• Statistical Analysis:
  • Descriptive: Medians with Interquartile Ranges (IQR) for continuous variables; frequencies for categorical variables.
  • Comparative: Mann-Whitney U tests (continuous) and Chi-square/Fisher's exact tests (categorical) to compare Title I vs. non-Title I schools. P-values were adjusted using the Holm-Bonferroni method.
  • Multivariable Modeling: Negative binomial regression for AED counts (with log enrollment as an offset) and logistic regression for CPR teaching presence.
  • Sensitivity Analysis: Median imputation was used for missing student training data to test robustness.
  • Software: Python 3.10 (scipy, statsmodels, scikit-learn).

3. Key Contributions

• First Statewide Assessment: Provides the first comprehensive, statewide data on CPR and AED resources across Massachusetts public high schools.
• Equity Focus: Specifically isolates and quantifies the disparity in student CPR training rates between Title I (low-income) and non-Title I schools, controlling for equipment availability.
• Gap Identification: Highlights the critical disconnect between schools offering CPR instruction and achieving universal student coverage.
• Methodological Framework: Demonstrates a rapid, low-cost audit approach that can be replicated by other states to monitor school cardiac preparedness and guide resource allocation.

4. Key Results

• Training Coverage:
  • 72.0% of responding schools reported teaching CPR.
  • However, only 10.0% of schools achieved 100% student training coverage, and only 15.0% reached at least 70% coverage.
  • The median student training rate was 138.2 per 1,000 students.
• Socioeconomic Disparities (Title I vs. Non-Title I):
  • Student Training: Title I schools had significantly lower training rates compared to non-Title I schools (Median: 50.3 vs. 199.8 per 1,000; adjusted p = 0.025).
  • Equipment Parity: Surprisingly, there were no significant differences in AED availability (Median: 9.2 vs. 6.9 per 1,000; p = 0.78) or manikin availability between Title I and non-Title I schools.
  • Staff Training: No significant difference in staff training rates was observed.
• Geographic Variation:
  • Significant geographic variation was found in both AED density and student training rates across counties (e.g., AEDs ranged from 3.5/1,000 in Suffolk to 33.3/1,000 in Dukes County).
• Equipment Gaps:
  • 22.9% of schools with non-missing data reported having zero CPR manikins, despite reporting CPR instruction.

5. Significance and Implications

• Public Health Impact: The findings suggest that while schools are a scalable mechanism for training the next generation of bystanders, current implementation is insufficient to ensure broad community readiness. The low coverage rates, particularly in Title I schools, may reinforce existing community-level disparities in cardiac arrest survival.
• Policy Recommendations:
  • Mandates: Supports the need for statewide CPR graduation requirements to ensure universal coverage.
  • Targeted Funding: Highlights the need for federal (e.g., HEARTS Act) and state funding specifically targeted at Title I districts to overcome implementation barriers, even if equipment is technically available.
  • Implementation Strategies: Suggests moving beyond simple equipment distribution to structured curriculum integration, centralized purchasing, and student-led programs (e.g., AHA HEART Clubs).
• Limitations: The study is limited by a modest response rate (24.2%), potential non-response bias (schools with no programs may have been less likely to respond), and self-reported data. However, sensitivity analyses confirmed that the observed disparities were robust.

Conclusion: The study concludes that the mere presence of CPR instruction in Massachusetts high schools does not equate to universal student training. There is a significant, inequitable gap in training coverage between Title I and non-Title I schools, driven not by a lack of equipment but likely by implementation and resource constraints. Addressing this requires targeted policy interventions to ensure equitable access to lifesaving skills.
