I have read the following:

  • The therapist (Valeriya Prokofieva) is obliged to act in accordance with legal regulations. The rights and obligations of client and care provider are laid down in, among other things, the Medical Treatment Agreement Act (WGBO) and the Healthcare Quality, Complaints and Disputes Act (Wkkgz).
  • The therapist keeps a client file. The client has the right to inspect his own file. The file will be kept for a total of 20 years in accordance with the legal retention period.
  • The therapist undertakes to provide information regarding the treatment to the client in all phases of the treatment. The client undertakes to provide relevant information to the therapist through the anamnesis interview.
  • The therapist maintains confidentiality with regard to information provided by the client, which is stored in the file. But with the exception of the data for which the client has stated that he/she does not object to the use for statistical purposes.
  • The therapist may not perform certain treatments without the client’s permission.
  • Supplementation of the care provider’s obligation to provide information: the focus will be on deciding “together” about treatment with the patient/client.
  • The therapist undertakes to correctly refer the client to a fellow therapist or a doctor if her treatment is not appropriate and/or sufficient.
  • Termination of the treatment can be done at any time by mutual consent. If the person requesting assistance no longer appreciates or considers it necessary to continue the agreement, he/she can terminate it unilaterally. If the person seeking help terminates the agreement against the therapist’s advice, the person seeking help will sign a statement at the therapist’s request in which he indicates that he has prematurely terminated the examination or treatment against the therapist’s advice.
  • The therapist can only terminate the agreement unilaterally, stating arguments, if he cannot reasonably be expected to continue the agreement. The therapist will continue to provide help and advice in such a situation until the person seeking help has been able to conclude an agreement with another care provider.
  • You have read the privacy regulations of the Valeria Lieveld practice and you agree to these regulations.
  • Payment method for the treatments is on account or in cash per consultation.
  • The client agrees to the rate of €95 (euros) per hour.
  • The client undertakes to cancel an appointment in a timely manner (at least 24 hours in advance), otherwise the costs of the reserved time may be charged.
  • For complaints about the treatment, the client can contact the professional organization www.lvnt.nl for the right to complain and for the disciplinary law to the TCZ Foundation, Tuchtrecht Complementaire Zorg (www.tcz.nu).
  • Any adverse consequences resulting from withholding information in the medical file at the GP are the responsibility and expense of the client.
  • There is a right of access for surviving relatives.
