Identification of Predictive Factors for observAnce of Transcutaneous Electrical NeuroStimulation (TENS) in Chronic Pain (IPATENS)
This is a retrospective and transverse multicenter study to identify predictive factors for adherence to TENS by chronic pain patients followed in structures specialized in Chronic Pain management (SPC).
The study contains 2 parts:
- A retrospective part of data collection in the patient follow-up file of the SPC during the 6 months elapsed after the first rental prescription.
- A transversal part, aimed at collecting additional information on the use of TENS, satisfaction and quality of life during a telephone interview after 6 months of use.

Popolazione di studio
The population studied is all adult chronic pain patients, who have benefited from an initiation of treatment with TENS dating back at least 6 months within a centre specialized in chronic pain management identified and labeled by a local regulatory agency.
Patients who agree to participate in the study will be recruited in reverse chronological order from the list of patients in the active queue of each centre. Ten patients will be recruited by each investigator with a total of 50 centers.

Chronic pain patients
|
Patients must fill questionnaires to collect socio-demographics, aetiology and characteristics of pain, efficacy and tolerance regarding the TENS. Study sites must fill questionnaires to collect information regarding the type of pain management centre, the characteristics of the clinician, the characteristics of the TENS prescribed. |
Cosa sta misurando lo studio?
Misure di risultato primarie
Misura del risultato |
Misura Descrizione |
Lasso di tempo |
---|---|---|
Determination of predictive factors explaining compliance to TENS.
Lasso di tempo: Data are collected the day of the inclusion retrospectively on a 6 month period prior to the inclusion of each patient
|
Compliance is evaluated on a 6 month period prior to the inclusion.
Compliant patients to TENS are defined as having 0, 1 or 2 to score of Morisky Medication Adherence Scale.
Factors which can explain the lack of compliance will be collected and categorized within "pain centre", "clinician", "TENS characteristics", "patient socio-demographics", "aetiology and characteristics of pain", "efficacy and tolerance" data.
