Recourse to radical prostatectomy and associated short-term outcomes in Italy: a country-wide study over the last decade
To estimate time trends in the recourse to radical prostatectomy (RP) and associated short-term outcomes after RP in Italy, as population-based data on RP adoption and outcomes are available mainly from Northern America and Northern Europe.
PATIENTS AND METHODS
All RPs for prostate cancer performed between 2001 and 2010 were extracted from the Italian national archive of hospital discharge records. Age-specific and age-standardised RP rates were computed. The effect of procedural volume on in-hospital mortality, complications, and length of stay (LOS) was estimated by multilevel regression models.
In all, 144 432 RPs were analysed. Country-wide RP rates increased between 2001 and 2004, and thereafter remained stable, with large differences between geographical areas. The mean hospital volume increased in the first study years, without centralisation but due to increasing RP numbers at the population level. The median LOS declined from 10 to 8 days over the study period (mean from 11.7 to 9.2 days). In-hospital mortality declined from 0.16% in 2001 to 0.07% in 2010. In-hospital mortality, LOS, and the prevalence of complications increased with age, and decreased with year of surgery. Compared with very low-volume hospitals, procedures performed in high-volume hospitals were associated with decreased in-hospital mortality, in-hospital complications, and LOS.
The study adds evidence on rapidly changing trends in RP rates in Italy, on improving in-hospital outcomes, and on their association with procedural volume.
