Timing of adoption of laparoscopic cholecystectomy in Denmark and in The Netherlands: a comparative study.

Laparoscopic cholecystectomy (LC) has diffused rapidly in most industrialised countries. The aim of this study has been to analyse the impact of different hospital characteristics on the hospital adoption of LC in Denmark and The Netherlands. Data on the timing of the adoption of LC and hospital characteristics (hospital size, teaching status and location) were retrieved in both countries. Proportional hazard regression was used to analyse different multivariate models. A total of 59 Danish and 109 Dutch hospitals adopting LC were identified. The multivariate analyses showed that increased hospital size was associated with relatively early adoption of LC in Denmark. Neither this nor other hospital characteristics influenced the timing of adoption in The Netherlands. As in other countries studied, hospital size is identified as an important factor in hospital adoption, whereas teaching status and location play a more limited role. The study shows that a multivariate method, such as the proportional hazard regression, can be used to elucidate differences among countries of the impact of different factors on the adoption of medium-ticket technologies like LC. Such multinational comparisons provide valuable information for health policy and planning.
