Introduction Inguinal hernias are repaired using either open or minimally invasive surgical techniques. For both types of surgery it has been demonstrated that a higher annual surgeon volume is associated with a lower risk of recurrence. This present study investigated the volume-outcome implications for recurrence operations, surgical complications, rate of chronic pain requiring treatment, and 30-day mortality based on the hospital volume. Materials and methods The data basis used was the routine data collected throughout the Federal Republic of Germany for persons insured by the Local General Sickness Fund "AOK" who had undergone inpatient inguinal hernia repair between 2013 and 2015. Complications were recorded by means of indicators. Hospitals were divided into five groups on the basis of the annual caseload volume: 1-50, 51-75, 76-100, 101-125, and ≥ 126 inguinal hernia repairs per year. The effect of the hospital volume on the indicators was assessed using multiple logistic regression. Results 133,449 inguinal hernia repairs were included. The incidence for recurrence operations was 0.95%, for surgical complications 4.22%, for chronic pain requiring treatment 2.87%, and for the 30-day mortality 0.28%. Low volume hospitals (1-50 and 51-75 inguinal hernia repairs per year) showed a significantly increased recurrence risk compared to high volume hospitals with ≥ 126 inguinal hernia repairs per year (odds ratio: 1.53 and 1.24). No significant correlations were found for the other results. Conclusions The study gives a detailed picture of hospital care for inguinal hernia repair in Germany. Furthermore, it was noted that the risk of hernia recurrence decreases in line with a rising caseload of the treating hospital.Publisher's Note Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations.
OP has the greatest risks of complication despite a low re-intervention rate. LVP demonstrated favourable results for transfusion and bleeding, but increased long-term re-interventions compared with TURP, while LEP showed increased re-interventions for bleeding. Findings support a careful indication and choice of method for surgery for LUTS, taking age and co-morbidities into account.
RP utilization in Germany is dropping, but the use of MIRP has risen steadily during the years 2005-2012, which is expected to have a positive impact on the morbidity of the operation.
This study represents the reality of healthcare for thyroid surgery in Germany. Additionally, it was determined that the risk for permanent vocal cord palsy after thyroid gland operations decreased with increasing case volumes of hospitals.
