RESUMO
Asthma exacerbations continue to be a major cause of visits to emergency departments (ED). Comprehensive care in the outpatient setting, with planning for early intervention for exacerbations, can reduce emergency visits. Thus, a major goal of ED intervention is to establish a link between the patient and the provider of ongoing asthma care, where complete education can be achieved and reinforced over time. When designing the Asthma 1-2-3 Plan discharge teaching tool for the ED, consideration was given to educational format, readability, patient population, and setting in which education was to be delivered. To evaluate use of the plan, ED records of patients enrolled in a separate asthma study, the Neighborhood Asthma Coalition (NAC), were audited for two 8-month intervals, May-December 1993 (before initiation of the plan) and May December 1994 (starting 1 month after completion of pilot testing on the plan in the ED). To evaluate effectiveness of the plan, records of physicians who cared for children in the NAC were evaluated. The database was reviewed for the date of the first visit for planned review of asthma that occurred after the acute asthma ED visit. After introduction of the plan, the proportion of children told to return to the physician for follow-up increased from 54% to 81%. The proportion of children given advice to return to their physician within the recommended 3 days or less increased from 11% to 54%. Chi2 Analyses showed that these changes were both statistically significant (p<0.0001). The plan was not effective in achieving increased follow-up visits for regular asthma care, in that 7% returned for follow-up within 7 days after an ED visit before the plan and only 6% returned for such a visit after the Plan. Successful initiation of a focused discharge teaching tool into the routine of the ED increased appropriate advice given at time of discharge from the ED. Although unsuccessful in increasing appropriate follow-up, the present intervention uses the ED not as a base for asthma education, but as a point for contacting patients in need of regular care and education, and for promoting access to that regular care.

In vitro production of the second and fourth components of complement (C2 and C4, respectively) by peritoneal macrophages from noninbred Hartley guinea pigs was tested after the animals had been inoculated with known carcinogens. The system demonstrated the capacity of N-nitrosodimethylamine to decrease C2 and C4 production. However, a similar decrease in C2 and C4 production was seen with only CCl4, 1 of the 10 chemical carcinogens studied. This system had little usefulness as a short-term screening procedure for the detection of carcinogenicity. The effect of the carcinogens on several other functions of peritoneal macrophages was also determined. The number of peritoneal exudate cells (PEC) was significantly lower in carcinogen-inoculated animals than in solvent-inoculated controls for three carcinogens: BeSO4, P < 0.005; CHCl3, P < 0.025; and CCl4, P < 0.01. However, the capacity of the PEC to adhere to plastic was decreased by only CHCl3 (P < 0.05), and adherent cells from all guinea pigs produced normal amounts of total secreted protein.
