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.

New pharmaceutical support (NPS)

Other

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.

Primary outcomes

  1. pourcentage of patients able to recall the correct name of the manufacturer brand or model of their prosthesis after traceability checking by a questionnaire at 6 months postoperative.

    Time frame: 6 month

Secondary outcomes

  1. pourcentage of patients who recall the reception of a patient-implant file during hospitalization by a questionnaire at 6 months postoperative.

    Time frame: 6 month

  2. pourcentage of patients able to identify three correct information after traceability checking on the implantation, by a questionnaire at 6 months postoperative

    Time frame: 6 month

    The three requested information are on the card or patient-implant sheet for this outcome are following :

    Item 1 : Accurate date of implantation : Date as DD/MM/YYYY format Item 2 : Surgeon's name who placed their prosthesis Item 3 : Batch number of one of the DMI composing their prosthesis : For hip prosthesis, question is about femoral head and for knee prosthesis, question is about tibial insert. If there is implantation of 2 breast prostheses, this is data from right prosthesis which are requested.

  3. pourcentage of patients who recall health institution where the prosthesis was implanted by a questionnaire at 6 months postoperative

    Time frame: 6 month

  4. pourcentage of patients who know there is a regular medical monitoring after implantation by a questionnaire at 6 months postoperative.

    Time frame: 6 month

  5. pourcentage of patients who recall material (s) composing the prosthesis by a questionnaire at 6 months postoperative.

    Time frame: 6 month

    Ability of patients to recall correct and useful characteristics for the identification of their prosthesis in the event of a descending health alert (so that the patient knows if he is affected by this alert)

  6. pourcentage of patients with breast implants who recall shape (anatomical or round) and surface texturing (smooth or textured) after traceability checking by a questionnaire at 6 months postoperative

    Time frame: 6 month

  7. pourcentage of patients with hip prosthesis who recall the location of the operative scar (anterior or posterolateral) and fixing method of the prosthesis (with ciment or without) by a questionnaire at 6 months postoperative

    Time frame: 6 month

  8. pourcentage of patients know they can report an adverse effect associated with the prosthesis by a questionnaire at 6 months postoperative

    Time frame: 6 month

  9. pourcentage of patients know institutions able to receive an adverse effect associated with the prosthesis (French agency for medicines and health products (ANSM), industrial, surgeon, other) by a questionnaire at 6 months postoperative.

    Time frame: 6 month
