RESUMO
The article deals with current issues and quality of the medical labour examinations (MLE) performed by MLE commissions, reveals the reasons accounting for discrepancies in MLE based on the data of the commissions and those of specialized clinics. A clinico-functional examination of 243 in-patient dust bronchitis cases established a late primary diagnosing of dust bronchitis as one of the reasons for invalidism. 3-rd group invalids were mostly workers with lengthy professional background but still before the retirement age, who needed social and labour rehabilitation. The main reason for the discrepancies lies in inadequate examination prior to the MLE commissions decision and prescription of invalidism to the patients with the initial stage of the disease basing on the social criterion.
