The implantable cardioverter-defibrillator: postcode prescribing in the UK 1998-2002

Area of Science:

• Cardiology
• Public Health
• Medical Device Technology

Background:

• Implantable cardioverter-defibrillators (ICDs) are crucial for preventing sudden cardiac death.
• European and national guidelines recommend ICDs for specific patient groups.
• Understanding implantation trends is vital for assessing healthcare access and effectiveness.

Purpose of the Study:

• To quantify the rate of ICD implantation in the United Kingdom between 1998 and 2002.
• To compare UK ICD implantation rates with European averages and national objectives.
• To identify geographical variations in ICD uptake across the UK.

Main Methods:

• An observational study design was employed, utilizing self-reported data with cross-checking for accuracy.
• Data collection was coordinated by the National Pacemaker and ICD Database, encompassing all UK ICD implanting centers.
• The study included all patients who received an ICD in the UK from 1998 to 2002, recording implantation dates and patient postcodes.

Main Results:

• ICD implantation rates in the UK demonstrated an increase over the five-year study period.
• Despite the increase, UK implantation rates significantly lagged behind the European average and established national targets.
• Substantial regional disparities in ICD implantation rates were observed across the United Kingdom.

Conclusions:

• The study highlights a concerningly low rate of ICD implantation in the UK.
• Significant regional variations in access to this evidence-based therapy were identified.
• Further investigation is warranted to elucidate the barriers hindering wider adoption of ICDs in the UK.
