Factors influencing surgeons' choice of method for hernia repair technique.

Tension-free hernioplasty is performed using prosthetic material in one-half of hernia repair procedures in Poland but in 85% of those in the region of Pomerania. This questionnaire study of surgeons in Pomerania examined their sources of knowledge about and the factors influencing their choice of groin hernia surgery. The questionnaire was sent to surgeons from 19 hospitals and was answered by 109 (83% of hernia surgeons in the region). We analyzed their reported knowledge of particular operative techniques, factors important in selecting the technique (personal experience, trends in surgical center), and the available sources of information (e.g., medical literature, internet, information from teachers, sales representatives). All respondents reported being familiar with and able to perform tension-free techniques, but only 44% are influenced by their individual professional skills in selecting the technique. Another 44% base their decision on trends in their hospital, and only 22% consider the patient's preferences. The most frequently quoted sources of scientific information are articles in the medical literature and conference reports (90%). Only 8% of the respondents are governed in their professional work by information from pharmaceutical company representatives. Most surgeons (70%) would prefer to make a decision about using a new surgical technique after practical training sessions or workshops led by experienced colleagues. In contrast to common opinion, the information from sales representatives are of only minor importance compared to that of evidence-based data and attendance at workshops and courses.
