Impact of Weekend Admission on Outcomes in Sinus Node Dysfunction and AV Block Undergoing Permanent Pacemaker: A...

Area of Science:

• Cardiology
• Health Services Research
• Medical Outcomes

Background:

• The
• weekend effect"
• is a known phenomenon associated with adverse outcomes in various cardiovascular conditions.
• Limited research exists on its specific impact on patients requiring permanent pacemaker (PPM) implantation for bradyarrhythmias.

Purpose of the Study:

• To investigate the association between weekend admissions and in-hospital outcomes for patients undergoing permanent pacemaker (PPM) implantation due to sinus node dysfunction (SND) or atrioventricular (AV) block.

Main Methods:

• A retrospective analysis of the 2022 National Inpatient Sample database.
• Identified adult patients hospitalized with SND or AV block who received PPM implantation.
• Stratified patients by admission day (weekend vs. weekday) and used multivariable regression models to assess outcomes like mortality, temporary pacemaker (TPM) placement, time to PPM implantation, and length of stay (LOS).

Main Results:

• The study included 29,630 patients with SND and 44,150 with AV block.
• For SND patients, weekend admission was not linked to increased mortality or TPM use but was associated with delayed PPM implantation and longer LOS.
• For AV block patients, weekend admission was not linked to increased mortality but was associated with higher TPM use, delayed PPM implantation, and longer LOS.

Conclusions:

• Weekend admissions for patients with SND or AV block requiring PPM implantation are not associated with increased in-hospital mortality.
• However, weekend admissions are linked to delays in permanent pacemaker implantation and extended hospital stays for these patient groups.
