[Treatment with human tetanus immunoglobulins in the Emergency Department. Effects of informed consent]

The impact of informed consent to tetanus prophylaxis with human immunoglobulins on patients treated in the Emergency Department has been evaluated.

Tetanus vaccination history was investigated in 1435 patients in 1995 and in 1300 patients in 1996 with post-traumatic skin lesions.

The study has shown that in 1995, 55% and in 1996 49.5% of the total patients studied had not received vaccine for tetanus or boosters for over 10 years. These patients had been proposed the treatment with human tetanus immunoglobulins (TIG). The research was performed comparing the consent obtained before (from 17/5 to 15/7/1995) and after (from 17/5 to 15/7/1996) the introduction of the informed consent. The survey was divided into 15-day periods. In 1995 prophylaxis with human immunoglobulins was refused by 42 patients out of 831 (5%) while, in the following year, by 284 out of 641 (44.3%). Every period examined has shown highly significant differences (p < 0.000).

Informing the patients that tetanus prophylaxis with human immunoglobulins can expose them to the risk, at present remote, of transmission of viral infections, has caused a heavy rise of denials to the suggestion of treatment with human immunoglobulins. The amount of the treated patients and the time that was devoted to informed consent would make Emergency Department one of the main places for effective and widespread tetanus prophylaxis. However a greater activity of outer structures would also be hoped for.
