Blood lines conduct leakage current during haemodialysis: a potential safety risk during first failure, especially for patients with central dialysis catheter as access.

Haemodialysis (HD) machines are IEC-classified as I type B. When central dialysis catheters (CDCs) are used for access, there will be close electrical contact with the heart. To investigate the risk for HD patients, the leakage of current through the tubing set was measured during in vitro dialysis performed according to the IEC 60601-1 standard for class I cardiac floating (CF) devices. A series of eight measurements were made with Gambro GFS + 12 dialysers, first with saline and then with blood in the blood lines. The leakage current exceeded the CF limit (50 microA) at the top of the CDC using the test 'mains on applied part' for saline (median 1008 microA, range 720-1241 microA), for blood (median 610 microA, range 449-772 microA) and also for a 'single fault condition' using saline (median 68 microA, range 35-118 microA) or blood (47 microA, range 4-128 microA). In the single fault condition, the highest leakage current at the CDC (128 microA) almost exceeded the earth leakage current in normal conditions. A safety risk can appear if a single fault arises in the dialysis machine or another device connected to the same patient, or during 'mains contact to the patient'. Then the current flow may be high enough to induce arrhythmias in the patient, especially when a CDC is used. These data and the use of CDCs as access for dialysis indicate that HD machines should be classified as cardiac floating rather than body (B) devices.

From teaching to learning. Experiences of small CME group work in general practice in Sweden.

OBJECTIVE: To describe the experiences of learning in small groups and the impact of small group continuing medical education (CME). DESIGN: Literature review, personal communication and critical reflection. SETTING: General practice in Sweden. SUBJECTS: Small CME groups. MAIN OUTCOME MEASURES: Occurrence, themes and impact of small CME groups. RESULTS: In 1998, there were approximately 230 small CME groups in Sweden, which means that nearly half of Swedish general practitioners (GPs) participated in such activities. Although widely used in Sweden, small CME groups are less practised than "traditional" CME activities, such as lectures. Group work might enhance knowledge development, enable the assessment of individual learning needs and facilitate the adoption of national guidelines and agreements between primary and secondary care. A competent group leader is crucial. CONCLUSION: A transition from passive to interactive learning in small groups is recommended.

[Better communication between primary health care providers and hospital physicians. The Danish health care consultation model].

A successful model of liaison between the primary and secondary (hospital) levels of health care entails improved co-operation between hospital doctors and general practitioners (GPs). Since its introduction in Denmark in 1991, this approach has been adopted in Sweden and, to a lesser extent, in Norway. Important principles of the model include: 1) both at the primary and secondary level, responsibility for cooperation rests with the physicians themselves; 2) all physicians at both levels are involved; 3) liaison is maintained by selected GPs serving as liaison officers acting in concert under the guidance of a coordinator; 4) liaison officers are responsible for cultivating personal contacts and good relations at hospitals, and promoting interest in and commitment to the system. Evaluation of the model requires both quantitative and qualitative studies. Although few evaluations have been completed, and no definite conclusions can be drawn, the preliminary results of current evaluations in progress in Sweden and Norway are promising, as are the reported experiences of those who use the system. A Nordic ad hoc group has been actively engaged in promoting the quality of primary-secondary health care liaison since 1997.
