A recent study has found that a positive correlation can be drawn to infer among the quality of treatment results for adult heart transplantations and the volume of services.
According to the Eurotransplant statistics, in hospitals with larger case volumes, fewer of the transplanted patients die, both in timely association with the intervention and in respect of total mortality.
However, the three observational studies included in the report show only a low informative value of results. 318 heart transplantations in Germany in 2018.
Heart transplantation may be medically indicated in the event of a severe cardiac failure that, despite the use of all other treatment options, is progressing and endangers the life of the patient concerned or extremely restricts his or her quality of life. After transplantation, lifelong immunosuppression is required to prevent organ loss due to transplant rejection. In the Eurotransplant region, the average survival time after surgery is currently eleven years.
According to the Eurotransplant statistics, a total of 318 heart transplantations were performed in Germany in 2018. The demand was considerably higher, but could not be met due to the shortage of donor organs.
For heart transplantations in adults in Germany, the G-BA has not yet established minimum volume standards for the provision of services in hospitals.
A positive correlation between case volumes and survival probabilities
In its worldwide literature searches, IQWiG identified three observational studies containing usable data for investigating the correlation between the volume of services and quality of treatment results for heart transplantations. All three studies analyse this correlation exclusively at the hospital level and not at the level of the surgeons involved in the transplantation.
For the outcome category "mortality", data are available for two outcomes: "all-cause mortality" and "intra- and perioperative mortality" (mortality before, during and immediately after surgery). For both outcomes, a reduction in the number of deaths in hospitals with more heart transplants per year can be inferred from the data.
For the outcomes "in-hospital mortality", "need for retransplantation", "health-related quality of life" (including activities of daily living and dependence on the help of others), as well as "length of hospital stay", the studies evaluated did not contain any data. Data were available for the outcome "adverse effects of treatment", but no statistically significant results could be inferred.
For heart transplantations in adults, IQWiG found no mengful studies examining the effects of specific minimum case volumes introduced into the health care system on the quality of treatment results.
