Key Takeaway

Note that standard cardiopulmonary resuscitation may improve survival rates following out-of-hospital cardiac arrest.

The researchers conducted a meta-analysis to evaluate the efficacy of standard cardiopulmonary resuscitation compared to chest compression-only techniques in patients experiencing out-of-hospital cardiac arrest who received bystander resuscitation. The primary objective was to determine if adding additional components to chest compressions improved survival rates at and beyond thirty days.

The analysis indicated that standard cardiopulmonary resuscitation led to improved survival outcomes compared to the compression-only approach. However, when evaluating secondary outcomes such as favorable neurologic performance, the authors did not find a statistically significant difference between the two methods of resuscitation. A positive trend was noted for neurological outcomes, but it did not reach significance.

The authors noted several limitations, specifically highlighting that there are currently not enough studies with randomized controlled designs and longer follow-up periods to establish robust clinical recommendations. Because the evidence base included cohort studies rather than exclusively randomized trials, the certainty of these findings is limited. Clinicians should consider these results as a signal for potential benefit in survival while remaining cautious regarding specific neurological improvements.

Researchers looked at the difference between two types of emergency care: standard cardiopulmonary resuscitation (CPR) and chest compression-only CPR. The study focused on patients who experienced a cardiac arrest in a public or private setting and received help from bystanders before professional medical teams arrived.

The analysis found that patients receiving standard CPR had a higher chance of surviving at least 30 days compared to those who received only chest compressions. While there was a slight trend toward better neurological outcomes for those receiving standard care, this specific result was not statistically significant and should be viewed with caution.

Because the data comes from observational studies rather than large-scale randomized trials, it is difficult to make firm recommendations. More high-quality research is needed to confirm these findings. Patients and families should discuss current emergency protocols with healthcare providers to understand what treatments are most effective for specific situations.

What this means for you:

Standard CPR may improve 30-day survival rates after cardiac arrest compared to chest compression alone.

Common questions

Does standard CPR improve survival after a heart attack?

The study found that standard cardiopulmonary resuscitation improved survival at and beyond 30 days compared to chest compression-only resuscitation. The results showed an odds ratio of 1.22 with a 95% confidence interval of 1.00 to 1.43. You should speak with a medical professional to discuss how these findings apply to emergency protocols.

Does standard CPR help with brain function after cardiac arrest?

While there was a trend toward better neurologic performance for those receiving standard cardiopulmonary resuscitation, the difference was not statistically significant. Because of this, it is not yet clear if standard care provides specific benefits for neurological outcomes compared to chest compression-only methods.

How reliable are these findings for emergency treatment?

The evidence is currently limited because the study included cohort studies rather than randomized controlled trials. There are not enough high-quality, randomized designs with long follow-up periods to make a definitive recommendation. Consult with medical experts regarding current best practices for out-of-hospital cardiac arrest.

INTRODUCTION: Out-of-hospital cardiac arrest is a global health concern, in which bystanders' ability and willingness to perform cardiopulmonary resuscitation determine the survival and neurologic performance of patients. This study aimed to synthesize the available evidence that compares the effects of standard cardiopulmonary resuscitation with chest compression-only cardiopulmonary resuscitation provided by bystanders in terms of survival and neurologic performance at 1 month or later after out-of-hospital cardiac arrest. METHODS: This systematic review with meta-analysis adhered to recognized reporting guidelines. The search strategy was performed in the MEDLINE, Embase, Cochrane Library, and Web of Science databases from inception to February 2025. The DerSimonian and Laird method was used to calculate odds ratios with 95% CIs. Standard cardiopulmonary resuscitation was considered the intervention group, and compression-only cardiopulmonary resuscitation was considered the control group. The risk of bias was assessed using the Newcastle‒Ottawa quality assessment scale. Egger's test and funnel plot symmetry were used to assess publication bias. RESULTS: Six cohort studies were included. A comparison of standard cardiopulmonary resuscitation and compression-only cardiopulmonary resuscitation performed by bystanders revealed that standard cardiopulmonary resuscitation improved survival at and beyond 30 days after out-of-hospital cardiac arrest (odds ratio, 1.22; 95% CI, 1.00-1.43; I = 90.9%; P≤.05). However, no significant differences were found in terms of favorable neurologic performance (odds ratio, 1.22; 95% CI, 0.96-1.48; I = 78.7%; P≤.05). DISCUSSION: Compared with compression-only cardiopulmonary resuscitation, bystander-provided standard cardiopulmonary resuscitation may increase survival after out-of-hospital cardiac arrest, with a positive (albeit nonsignificant) trend toward better neurologic performance. However, there are not enough studies with randomized controlled designs and longer follow-up periods to establish robust recommendations.
