What's known on the subject? and What does the study add?

Adverse outcomes after radical prostatectomy are more often recorded in the elderly.

In the USA, elderly patients undergoing radical prostatectomy are treated at institutions where suboptimal outcomes are recorded.

OBJECTIVE

  • • To assess the rate of adverse outcomes after open radical prostatectomy (ORP) in the elderly and to examine the effect of annual hospital caseload (AHC) and academic institutional status on adverse outcomes in these of patients.

PATIENTS AND METHODS

  • • Within the Health Care Utilization Project Nationwide Inpatient Sample, we focused on ORPs performed between 1998 and 2007. Subsequently, we restricted to patients aged ≥75 years.
  • • In both datasets, we examined transfusion rates, intra-operative and postoperative complication rates, and in-hospital mortality rates.
  • • Stratification was performed according to AHC tertiles and academic status.
  • • Multivariable logistic regression analyses were fitted.

RESULTS

  • • Of 115 554 ORP patients, 2109 (1.8%) were aged ≥75 years.
  • • In multivariable analyses performed in the entire cohort, elderly age increased homologous blood transfusion rates (P < 0.001), intra-operative (P= 0.001) and postoperative (P < 0.001) complication rates, and the mortality rate (P= 0.007).
  • • Most elderly were treated at low or intermediate AHC (68.5%) and non-academic centres (56.2%).
  • • Within the elderly cohort, intra-operative (2.9%) and postoperative (22.2%) complications tended to be highest at low AHC institutions compared to institutions of intermediate (2.7% and 17.4%) and high AHC (1.7% and 14.5%). Similarly, intra-operative (2.7% vs 2.1%) and postoperative complications (19.1% vs 13.9%) tended to be higher at non-academic than academic centres.
  • • In multivariable analyses performed in the elderly subgroup, low AHC predicted higher intra-operative complications and higher homologous transfusions, whereas non-academic status predicted higher postoperative complications.

CONCLUSIONS

  • • Adverse outcomes are more often recorded in the elderly.
  • • Most elderly are treated at institutions where suboptimal outcomes are recorded.
