Regional variation in electroconvulsive therapy use

Area of Science:

• Psychiatry
• Health Services Research

Background:

• Electroconvulsive therapy (ECT) is a highly effective depression treatment.
• Previous analyses in Ireland underestimated ECT use due to incomplete data, particularly excluding independent sector patients.
• This led to perceived significant regional variations in ECT provision.

Purpose of the Study:

• To accurately assess regional variation in electroconvulsive therapy (ECT) use in Ireland.
• To investigate the impact of including independent sector data on ECT utilization estimates.
• To explore potential service-related factors influencing ECT treatment rates.

Main Methods:

• Data from public and independent sectors were combined for a comprehensive analysis of 2008 ECT usage.
• Statistical methods, including chi-squared tests, were used to quantify inter-regional variation.
• Correlation analyses examined relationships between ECT rates, depressed admissions, and hospital bed availability.

Main Results:

• Combining public and independent sector data significantly reduced the observed inter-regional variation in ECT use (chi-squared from 83 to 30).
• The Western region showed the largest contribution to the remaining variation.
• A negative correlation was found between the ratio of ECT programs to depressed admissions and the rate of depressed admissions (r = -0.53, p = 0.01).
• Depressed admission numbers positively correlated with acute beds per area (r = 0.68, p = 0.001).

Conclusions:

• Regional variation in electroconvulsive therapy (ECT) is less pronounced than previously reported when all patient sectors are considered.
• Service factors, such as the characteristics of smaller centers admitting severely ill patients, likely play a significant role in ECT utilization.
• Accurate ECT service planning requires comprehensive data encompassing all healthcare sectors.
