[Computer-supported patient history: a workplace analysis].

Since 1991, an extensive computer network has been developed and implemented at the Cantonal Hospital of Lucerne. The medical applications include computer aided management of patient charts, medical correspondence, and compilation of diagnosis statistics according to the ICD-9 code. In 1992, the system was introduced as a pilot project in the departments of pediatrics and pediatric surgery of the Lucerne Children's Hospital. This new system has been prospectively evaluated using a workplace analysis. The time taken to complete patient charts and surgical reports was recorded for 14 days before and after the introduction of the computerized system. This analysis was performed for both physicians and secretarial staff. The time delay between the discharge of the patient and the mailing of the discharge letter to the family doctor was also recorded. By conventional means, the average time for the physician to generate a patient chart (26 minutes, n = 119) was slightly lower than the time needed with the computer system (28 minutes, n = 177). However, for a discharge letter, the time needed by the physician was reduced by one third with the computer system and by more than one half for the secretarial staff (32 and 66 minutes conventionally; 22 and 24 minutes respectively with the computer system; p < 0.0001). The time required for the generation of surgical reports was reduced from 17 to 13 minutes per patient and the processing time by secretaries from 37 to 14 minutes. The time delay between the discharge of the patient and the mailing of the discharge letter was reduced by 50% from 7.6 to 3.9 days.(ABSTRACT TRUNCATED AT 250 WORDS)

[Effect of conjugated PRP vaccines on the incidence of invasive diseases caused by Haemophilus influenzae Type B in childhood].

Prior to the introduction of conjugate vaccines, Haemophilus influenzae type b (Hib) was the leading cause of severe invasive infections in young children, in Switzerland as in other countries. From 1976 to 1990, 150 children were treated for Hib meningitis at the Children's Hospital of Lucerne, corresponding to an annual incidence of 9.2 cases per 100,000 children aged under 15 years. In the same time period, the case fatality rate for meningitis was 4%. 87.3% of the meningitis cases occurred among children aged under 5 years. For this age group an annual incidence of 26.4 cases per 100,000 children was calculated. From 1979 to 1990, 141 children were hospitalized for epiglottitis, corresponding to an annual incidence of 10.9 cases per 100,000 children aged under 15. The introduction of conjugated vaccines resulted in a significant reduction in the frequency of invasive Hib disease. From 1991 to 1992, 9 cases each of meningitis and epiglottitis were observed. In 1993, only one case of meningitis and 2 cases of epiglottitis were seen. For children under 15 years these 21 cases represent annual incidences of 3.2 cases of meningitis and 3.6 cases of epiglottitis per 100,000 children. 2 of 10 meningitis cases occurred in twice vaccinated children under 2 years of age with no signs of immunodeficiency, and another case was seen in a 5-month-old infant vaccinated with only one dose. Assuming a vaccination coverage of 70% among children under 5 during the years 1991 and 1992, the calculated efficacy is 80 to 85% for the vaccine PRP-D in this predominantly affected age group during the period when only this vaccine was available.(ABSTRACT TRUNCATED AT 250 WORDS)
