IQWiG Reports – Commission No. V21-04

Key statement

Research question:

The objective of this investigation is to update Rapid Report V18-02. Hence, this rapid report aims to answer the same research questions as Rapid Report V18-02:

– present and assess the correlation between volume and quality of treatment outcome in allogeneic stem cell transplantation (SCT) in adults (research question 1a)

– present and assess the correlation between volume and quality of treatment outcome in autologous SCT in adults (research question 1b)

– present and assess studies which investigate the effects of a minimum number of cases of SCT introduced into the healthcare system on the quality of treatment outcomes (research question 2)

Conclusion:

For the investigation of any correlation between volume and quality of treatment outcome in allogeneic SCT (research question 1a) and autologous SCT (research question 1b), the present rapid report was able to include 1 observational study each. Both studies investigated volume solely on the transplantation centre (TC) level and quality of treatment outcome solely for the outcome of all-cause mortality.

Regarding allogeneic SCT, on the basis of 1 study of high informative value of results, the present rapid report derived a correlation between volume and quality of treatment outcome in favour of higher-volume TCs for the outcome of all-cause mortality. This result supports the conclusion of Rapid Report V18-02.

Regarding autologous SCT, the 1 study of low informative value of results did not allow the present rapid report to derive any correlation between TC volume and quality of treatment outcome. This result does not alter the conclusion of Rapid Report V18-02, which derived a correlation.

No studies were found for investigating the effects of specific minimum case numbers implemented in patient care for SCT on the quality of treatment outcomes (research question 2).
