Background:
Existing population-based reports on complication rates after minimally invasive radical prostatectomy (MIRP) did not address temporal trends.
Objective:
To examine contemporary temporal trends in perioperative MIRP outcomes.
Design, Setting, And Participants:
Between 2001 and 2007, 4387 patients undergoing MIRP were identified using the Nationwide Inpatient Sample.
Measurements:
To examine the rates and trends of intraoperative and postoperative complications, transfusion rates, length of stay in excess of the median, and in-hospital mortality. We tested the effect of the late (2006-2007) versus the early (2001-2005) study period on all outcomes using multivariable logistic regression models controlled for clustering among hospitals.
Results And Limitations:
Intraoperative and postoperative complications decreased from 7.0% to 0.8% (p < 0.001) and from 28.5% to 8.7% (p < 0.001), respectively. Transfusion rates decreased from 3.5% to 2.1% (p = 0.3). Hospital length of stay >2 d decreased from 56% to 15% (p < 0.001). In multivariable analyses, intraoperative (odds ratio [OR]: 0.41; p = 0.002) and postoperative (OR: 0.65; p = 0.007) complications were less frequent in the late versus the early study period. Late study period patients were less likely to stay >2 d than early study period patients (OR: 0.34; p > 0.001). Limitations of these findings include the lack of adjustment for several patient variables including disease characteristics, surgeon variables including surgeon caseload, and the restriction to in-hospital events.
Conclusions:
Our analyses demonstrate that in-hospital complication rates and length of stay after MIRP decreased over time. This implies that temporal differences specific to complication rates after MIRP must be considered when comparisons are made with other radical prostatectomy techniques.
Insights
Complication rates and hospital stays after minimally invasive radical prostatectomy (MIRP) significantly decreased between 2001 and 2007. These findings highlight important temporal trends in MIRP outcomes.
Area of Science:
- Urology
- Surgical Outcomes
- Health Services Research
Background:
- Population-based reports on minimally invasive radical prostatectomy (MIRP) have not previously analyzed temporal trends in complication rates.
- Understanding these trends is crucial for evaluating surgical techniques and patient outcomes over time.
Purpose of the Study:
- To investigate contemporary temporal trends in perioperative outcomes associated with MIRP.
- To identify changes in complication rates, transfusion needs, and hospital length of stay over a defined period.
Main Methods:
- Analysis of 4387 patients who underwent MIRP between 2001 and 2007, using data from the Nationwide Inpatient Sample.
- Comparison of outcomes between an early (2001-2005) and a late (2006-2007) study period using multivariable logistic regression, controlling for hospital clustering.
Main Results:
- Significant decreases observed in intraoperative complications (7.0% to 0.8%) and postoperative complications (28.5% to 8.7%).
- Transfusion rates decreased from 3.5% to 2.1%, though not statistically significant (p=0.3).
- Hospital length of stay exceeding 2 days decreased substantially from 56% to 15% (p < 0.001).
Conclusions:
- In-hospital complication rates and length of stay following MIRP have demonstrably decreased over time.
- Temporal variations in MIRP outcomes should be considered when comparing it with other radical prostatectomy methods.
- Further research should aim to adjust for patient and surgeon-specific variables for a more comprehensive analysis.
