One-on-one long-term tutorials in general practitioners' practices - a successful new teaching concept in primary care medicine.

To improve teaching in practical and communicative skills and knowledge in day-to-day medical practice, in 1997 we introduced one-on-one tutorials in general practitioners' offices as a mandatory part of medical students' academic education. Students participate actively half a day per week in their 3rd and 4th academic years (out of 6) in the office or clinic of a trained personal tutor. We recruited 270 general practitioners in town or from surrounding rural areas for this purpose. 85% of students choose general practitioners as their tutors and 15 % tutors in hospitals. To test whether the tutorials' aims were achieved, in 2005 we performed a detailed questionnaire evaluation after seven years' experience of one-on-one tutorials. All 236 students involved were asked to participate. The response rate was almost complete (98%). 233 anonymous questionnaires were analysed. Students reported improvement in knowledge, social and communicative skills and personal motivation. The overall rating of the one-on-one tutorials obtained 5.3 on a 6 point scale and achieved the top ranking among all university medical faculty classes. In-practice long-term one-on-one medical student-general practitioner tutorials can be recommended for implementation.

Measurement of lung volume in mechanically ventilated monkeys with an ultrasonic flow meter and the nitrogen washout method.

OBJECTIVE: Measurement of functional residual capacity (FRC) during mechanical ventilation is important to standardise respiratory system compliance and adjust the ventilator settings to optimise lung recruitment. In the present study we compared three methods to measure FRC. DESIGN: The bias flow nitrogen washout technique (FRC(N2MC)), the multiple breath nitrogen washout (FRC(MBNW)) and the multiple breath sulphur-hexafluoride washout using the molar mass signal of an ultrasonic flow meter (FRC(MBSF6)) were compared in six adult monkeys after endotracheal intubation and during spontaneous breathing and mechanical ventilation at three different positive end-expiratory pressure (PEEP) levels of 0, 5 and 10 cmH2O. SETTING: Animal research laboratory. RESULTS: We found good agreement between all three methods and they all accurately measured changes in FRC when PEEP was increased. The coefficients of variance of the three measurement techniques were in the same range (1.3-9.2%). CONCLUSION: The measurement of the tracer gas concentration with the molar mass signal of the ultrasonic flow meter provides a good and simple alternative to respiratory mass spectrometer for FRC measurements in ventilated subjects.

One-on-one tutorials in private practices and clinics: four years of experience in Basel, Switzerland.

The one-on-one tutorial is a new form of learning that is practice oriented. It is based on a teacher-student relationship continuing over two years. Since 1997, third- and fourth-year students have worked for one half day per week under the supervision of their tutor, be it in a private practice or in a hospital. This programme facilitates direct patient contact at an early stage of medical school. In addition, it allows students to apply their knowledge in everyday life. The interactive form of learning is of paramount importance in this module. The ARIVA learning model was developed specially for third-year students and the logbook for fourth-year students. After each tutorial third-year students completed the ARI VA worksheet and fourth-year students completed the logbook. They were handed in together with the structured learning report. Between 85 and 109 students per year participated in these tutorials, totalling 733 students. Each student was taught an average of 3.1 patients in the presence of the tutor. In addition students examined an average of 2.4 patients independently and fulfilled an average of 1.2 practical tasks. For the fourth-year students the number of contacts with patients and the spectrum of diseases examined are impressive. All learning goals were fulfilled The one-on-one tutorial is a practice-oriented, interactive learning method. It uses a variety of didactic methods based on the principals of problem-oriented learning. In a relatively early stage of their medical education one-on-one tutorials give students the opportunity to learn independently how to interview and examine patients. They also give students the possibility to acquaint themselves with a multitude of diseases with the aid of instructions and demonstrations. They are conducive to work with patients above all because students learn how to perform certain techniques.
