Die Häufigkeit von Operationen in der Schweiz nach Versicherungsstatus


Bisig, Brigitte; Gutzwiller, Felix; Domenighetti, Gianfranco (1998). Die Häufigkeit von Operationen in der Schweiz nach Versicherungsstatus. Swiss Surgery, 4(3):109-116.

Abstract

Several studies reported in the literature show that surgical procedures can be carried out for other than clinical indications. In Switzerland, no statistics on the "demography" of surgical procedures are available. But an earlier analysis of the "Swiss Health Survey 1992/93" gave first indications on differences in rates of surgical procedures (hysterectomy, appendectomy, tonsillectomy and operation of the hip and gallbladder) by sex, educational status and region. This study, based on the same datasource (N = 10792), reveals an additional link with the health insurance status. The prevalence of surgical procedures is higher in privately insured than in persons with only basic insurance, independent of age, sex and region. The highest rates of surgical procedures (except tonsillectomy) are found among privately insured persons with a low educational status. Among 25-74 year old privately insured women, the lifetime-prevalence of a hysterectomy is 30% with low and 13% with high educational status (p < .001). The corresponding prevalences of at least one of the mentioned surgical procedures (without tonsillectomy) are 49% versus 28% (p < .001). As these are lifetime-prevalences, these rates do not necessarily reflect the actual surgical procedures. However, an analysis of the period of operation for hysterectomy and for the gallbladder shows the same pattern as the mentioned lifetime-prevalences. Higher rates among privately insured are also a frequent finding in the international literature. These findings should stimulate patients to ask for a "second opinion". Furthermore, there is an urge for the implementation of general hospital statistics to verify such findings. In addition, the scientific consensus on the indication of several surgical procedures should be promoted on the way to more evidence-based-medicine.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
