Referral determinants in Swiss primary care with a special focus on managed care.

Studies have shown large variation of referral probabilities in different countries, and many influencing factors have been described. This variation is most likely explained by different healthcare systems, particularly to which extent primary care physicians (PCPs) act as gatekeepers. In Switzerland no mandatory gatekeeping system exists, however insurance companies offer voluntary managed care plans with reduced insurance premiums.

Referral rates in Swiss primary care with a special emphasis on reasons for encounter.

Questions Under Study: Referrals from primary to secondary care reflect a crucial role of primary care physicians (PCPs). Most referral rates are based on the number of consultations, rather than on the number of problems addressed during consultations (reasons for encounter = RFE). The aim of the study was to update data on consultations, RFE and referrals in Swiss primary care and calculate a referral rate based on RFE rather than on the number of consultations.

Propofol sedation alone or in combination with pharyngeal lidocaine anesthesia for routine upper GI endoscopy: a randomized, double-blind, placebo-controlled, non-inferiority trial.

Background: In patients undergoing routine upper EGD, propofol is increasingly used without pharyngeal anesthesia because of its excellent sedative properties. It is unclear whether this practice is non-inferior in regard to ease of endoscopic intubation and patient comfort.

Objective: To assess the relevance of local pharyngeal anesthesia regarding the ease of EGD performance in patients sedated with propofol as monotherapy.
