[Winter epidemic of carbon monoxide poisoning in Badia].

Objective: To find the incidence, morbidity and possible causes of the acute carbon monoxide poisonings (ACMP) which occurred in Badia between january 1992 and june 1993.

Design: A longitudinal, retrospective study.

Patients: Every Badia resident discharged from the Hospital Consortium of Parc Taulí, Sabadell with a diagnosis of ACMP and/or from Barcelona's Red Cross Hospital (RCH) after hyperbaric treatment was considered.

[Suitability of the practice of recording only the main health problem in primary care].

Objective: To analyse if recording only the main health problem (P) can reflect in a valid way the totality of health problems (P+S) cared for and all the actions generated by a consultation.

Design: Using a representative sample of the patients seen at the centre over a three-month period, information on P+S was gathered, P was identified and the actions generated by each one of the problems were recorded. Health problems were codified through CIPSAP-2-D and grouping diagnoses.
