The frequency of five common, in-hospital surgical procedures appeared to vary between Dutch provinces in 1985. The degree of variation was largest for (adeno)tonsillectomies (the highest and lowest values differed by a factor of 2.6), and smallest for abdominal hernia operations (difference a factor of 1.1). Appendectomies, cholecystectomies and hysterectomies showed a moderate degree of variation (differences a factor of 1.4-1.6). The possible causes of these differences are not known with certainty, but results from studies in other countries suggest that differences in practice styles may be involved. Information to surgeons and other specialists on interregional variation in surgical procedures could play an important role in the identification of areas where consensus development, or consensus promoting research, is necessary.
1985年，荷兰各省之间五种常见的住院外科手术的频率似乎有所不同。（腺）扁桃体切除术的变异程度最大（最高值与最低值相差2.6倍），腹部疝气手术的变异程度最小（相差1.1倍）。阑尾切除术、胆囊切除术和子宫切除术的变异程度适中（相差1.4 - 1.6倍）。这些差异的确切原因尚不确定，但其他国家的研究结果表明，可能涉及手术方式的差异。向外科医生和其他专家提供有关手术程序区域间差异的信息，可能在确定需要达成共识或促进共识的研究领域方面发挥重要作用。
