Background. Few studies have addressed the frequency and the consequences of the appropriateness of referrals for patch testing. Objectives. To analyse the appropriateness of referrals for patch testing among patients seen in the Allergy Unit, University of Ferrara, and to evaluate whether this selection influences the results of the test. Patients and methods. One thousand six hundred and twenty-seven consecutive patients were enrolled, and 1528 patients were patch tested. On the basis of the history and clinical picture, the appropriateness of referrals for patch testing was judged. Results. Of the patients, 82.30% attended the Allergy Unit with a clinical presentation and/or history considered to be an appropriate indication for patch testing. The rate of appropriate referrals for patch testing from dermatologists was significantly higher (p < 0.001) than that for referrals from other physicians. The sensitization rate was significantly higher among the appropriate referrals than among the inappropriate ones, both in the entire sample (p < 0.001) and in atopic patients (p = 0.012). Conclusions. Clinical experience was seen to be crucial for the appropriate selection of patients. Furthermore, appropriate referral for patch testing was shown to influence the sensitization rate. © 2011 John Wiley & Sons A/S.

Abstract
Background. Few studies have addressed the frequency and the consequences of the appropriateness of referrals for patch testing. Objectives. To analyse the appropriateness of referrals for patch testing among patients seen in the Allergy Unit, University of Ferrara, and to evaluate whether this selection influences the results of the test. Patients and methods. One thousand six hundred and twenty-seven consecutive patients were enrolled, and 1528 patients were patch tested. On the basis of the history and clinical picture, the appropriateness of referrals for patch testing was judged. Results. Of the patients, 82.30% attended the Allergy Unit with a clinical presentation and/or history considered to be an appropriate indication for patch testing. The rate of appropriate referrals for patch testing from dermatologists was significantly higher (p < 0.001) than that for referrals from other physicians. The sensitization rate was significantly higher among the appropriate referrals than among the inappropriate ones, both in the entire sample (p < 0.001) and in atopic patients (p = 0.012). Conclusions. Clinical experience was seen to be crucial for the appropriate selection of patients. Furthermore, appropriate referral for patch testing was shown to influence the sensitization rate. © 2011 John Wiley & Sons A/S.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
