[The identification of the drawbacks in the provision of medical assistance based on the so-called biased data].

The authors discuss a case of inadequate provision of emergency care encountered in expert practice. The analysis of the difficulties currently facing experts engaged in the verification of medical diagnoses is described as exemplified by the patient presenting with the obstetric and gynecological problems and the aggravated medical history. The case under consideration is characterized by the almost total absence of the relevant comprehensive medical documentation concerning a women pregnant with twins. The data are presented needed to perform the expert evaluation and formulate the objective and scientifically sound conclusions about the cause-and-effect relationships between the drawbacks in the provision of medical assistance and the unfavourable outcome of pathological conditions.
