High costs in the German health care system and a lack of nursing staff make a shift from inpatient to outpatient treatment unavoidable. The new catalogue announced for outpatient surgical procedures will contain up to 50% of all procedures in urology. In anticipation of these major changes, neither hospitals nor medical practices are able to prepare adequately since the precise catalogue, the infrastructural changes required, and the rules of remuneration have not yet been clarified. Without some degree of certainty for planning, nobody will be able or willing to invest into future structures.
