A Randomized Study of Superiority of POSToperative Pharmaceutical Support on Patients' Knowledge of Their IMPlant

Recently joint and breast prostheses were placed under special post-marketing surveillance in order to prevent new occurrence of serious incidents by agency for medicines and health products safety. Few of french patient are able to identify their prosthesis in the event on health security alert. An usual postoperative pharmaceutical support (UPS) for patients with joint prosthesis has been implemented to prepare them for return home. At the request of surgeons, a new pharmaceutical support (NPS) has been developed to improve the ability of these patients to recall or find information that identify their prosthesis.

Objectives :

The main objective is to demonstrate that the new pharmaceutical support (NPS) increase the ability to memorize then find correct information of their prosthesis 6 months post-implantation

Material and method :

This study, approved by an ethic committee, takes place in the orthopedic and plastic surgery departments. The 236 adult patients included are hospitalized following the scheduled placement of either a breast or a hip or knee prosthesis. They are randomized, either in the NPS group or in the UPS comparator group. In both cases, patients benefit from the same written information: a patient-implant file and an information booklet specific to their prosthesis, validated by specialist surgeons, to prepare for their return home. The only difference between these 2 groups is that patients in the NPS group benefit from additional visual and oral information on the characteristics of their implant and on medical device vigilance during their hospitalization. In NPS group, pharmacist use specific photo and quiz.

A telephone follow-up at the 6th month of the patients is carried out by a pharmacist to assess the patient's knowledge, using a standardized questionnaire.

Expected results :

Based on retrospective data already published, the main hypothesis is that the NPS is associated with an improvement in patient ability to remember the correct model or manufacturer of their prosthesis, compared to the UPS, 6 months after the operation.Secondary hypotheses are that NPS compared to UPS leads to an improvement in patients ability to preserve and find correct items related to theirs prosthesis at 6 months as well as an improvement in their knowledge of medical device vigilance and patient satisfaction declarations and a decrease in anxiety associated with prosthesis.
