title: Achieving minimum caseload requirements: an analysis of hospital quality control reports from 2004-2010.
abstract: BACKGROUND
  Legally mandated minimum hospital caseload requirements for certain invasive procedures, including pancreatectomy, esophagectomy, and some types of organ transplantation, have been in effect in Germany since 2004. The goal of such requirements is to improve patient care by ensuring that patients undergo certain procedures only in hospitals that have met the corresponding minimum caseload requirement. We used the case numbers published in legally mandated hospital quality control reports to determine whether the hospitals actually met the stipulated requirements.
  
  
  METHODS
  We performed a secondary analysis of data supplied by hospitals in their quality control reports for the years 2004, 2006, 2008, and 2010 with respect to six procedures that have a minimum caseload requirement: complex interventions on the esophagus and pancreas, total knee replacement, and hepatic, renal, and stem-cell transplantation.
  
  
  RESULTS
  The total case numbers for these six different procedures rose from 22 064 (0.1% of all procedures) in 2004 to 170 801 (0.9% of all procedures) in 2010. From 2006 onward, procedures to which minimum caseload requirements apply have been carried out in half of all hospitals studied. These procedures account for 0.9% of all inpatient cases in Germany. The percentage of hospitals that continue to perform certain procedures despite not having met the minimum caseload requirement ranged from 5% to 45%, depending on the type of procedure, and the percentage of cases carried out in such hospitals ranged from 1% to 15%. These values remained nearly constant for each of the six minimum caseload requirements over the 4 reporting years for which data were examined.
  
  
  CONCLUSIONS
  The establishment of minimum caseload requirements in Germany in 2004 did not lessen the number of cases performed in violation of these requirements over the period 2004 to 2010.
