Summary
Total abdominal hysterectomy (TAH) rates declined while supracervical hysterectomy (SCH) rates increased in the US from 1991-1994. TAH remained the dominant procedure, despite SCH being more costly.
Area of Science:
- Gynecologic Surgery
- Health Services Research
- Surgical Trends
Background:
- Hysterectomy is a common surgical procedure for benign gynecologic conditions.
- Abdominal hysterectomy is performed using total (TAH) or supracervical (SCH) techniques.
- Understanding national practice trends is crucial for resource allocation and surgical education.
Purpose of the Study:
- To analyze nationwide practice trends for TAH and SCH in the United States between 1991 and 1994.
- To compare the utilization rates and associated hospital charges for TAH and SCH.
- To identify shifts in surgical technique preference over a four-year period.
Main Methods:
- Utilized the HCUP-3 NIS database for inpatient discharges from 1991 to 1994.
- Focused on TAH and SCH procedures, excluding vaginal or laparoscopic approaches and hysterectomies for malignancy.
- Evaluated annual numbers, rates, average length of stay, and mean institutional charges for each procedure.
Main Results:
- The national TAH rate decreased significantly from 25.7 to 20.5 cases per 10,000 females (P=0.02).
- The national SCH rate significantly increased from 0.16 to 0.41 cases per 10,000 females (P=0.04).
- TAH consistently represented over 99% of abdominal hysterectomies; SCH generally incurred higher institutional charges than TAH.
Conclusions:
- Significant shifts in US hysterectomy techniques occurred between 1991 and 1994, with declining TAH and rising SCH rates.
- Despite the observed changes, a strong preference for TAH persists.
- SCH is more expensive than TAH, but its low utilization minimizes its impact on national healthcare expenditures; further research into causative factors is warranted.
