Registration Number

Lead Sponsor
Nantes University Hospital
Brief Summary

The purpose of this study is to determine the cost-effectiveness of vocal rehabilitation with reinforced inter-tracheoesophageal voice prosthesis versus standard voice prosthesis in case of repeated intra-prosthetic leakage in total laryngectomy patients.

This is a one year medico-economic study involving patients carrying a standard voice prosthesis implant and having undergone 2 successive prosthesis replacements within 3 months of interval and/or requiring at least 4 changes in the last 12 months, for intraprosthetic leakage.

Eligible subjects will be randomized in 2 groups: reinforced prosthesis with silver coating and double valve (Dual Valve) or standard prosthesis (single unreinforced valve), of the same model as the prosthesis previously implanted in the patient.

Detailed Description

Prosthetic voice rehabilitation is a widespread practice that allows the patient to resume phonation quickly after total laryngectomy/total pharyngolaryngectomy/total circular pharyngolaryngectomy.

When the longevity of the implant is abnormally short (less than 3 months), the multiplication of changes is likely to increase the risk of overall morbidity related to maintaining the functionality of the voice prosthesis and to alter the patient's quality of life.

Reinforced innovative prostheses, currently not supported by the French Social Security, delay the occurrence of intraprosthetic leakage compared to standard prostheses.

This study assesses the economic efficiency from a societal perspective and a one-year time horizon, from vocal rehabilitation with reinforced inter-tracheoesophageal prosthesis versus standard voice prosthesis in case of intra-tracheal leakage in total laryngectomy patients.

Patients are randomized in 2 arms. Arm A usual care with reinforced prosthesis, or arm B usual care with standard prosthesis. Each patient is followed during 12 months.

Primary Outcome Measures
NameTimeMethod
Incremental Cost-Effectiveness Ratio (cost per avoided prosthesis change), based on a societal perspective, comparing the use of a reinforced voice prosthesis to the use of a standard prosthesis12 months

Effectiveness will be measured by the mean of number of prosthesis changes in each arm. Costs will be measured by 1) Outpatient resource consumption collected in a declarative patient questionnaire and 2) Hospital care resources using the database of the Medicalised Information System Program of each recruiting site

Secondary Outcome Measures
NameTimeMethod
Quality of life using the Head and Neck Quality of Life Questionnaire (QLQ - H&N 35)Baseline, 3 months, 6 months, 9 months and 12 months

Score of the QLQ - H\&N 35, including 35 questions assessing other aspects of quality of life in patients with head and neck cancer. The total score ranges from 0 to 100

Quality of voiceBaseline, 3 months, 6 months, 9 months and 12 months and at each voice prosthesis replacement

score of the Voice Handicap Index: 10 items assessing the patient's voice, with 5 possible answers per item ranking from "never" to "always". The total score ranges from 0 to 120

Patient quality of voice assessed by the patient's relativeBaseline, at 3 months, 6 months, 9 months and 12 months

Voice quality assessed by the patient's relative if present at time of prosthesis replacement, with a numeric scale ranging from 0 "worst possible voice" to 10 "best possible voice", before and after each voice prosthesis change

Time spent out of home12 months

Time spent by the patient out of home induced by voice prosthesis leaks, declared by the patient

Interruption of oral communication12 months

Number of days or hours during which the patient could not speak due to voice prosthesis leak, declared by the patient

Frequency of voice prosthesis replacements12 months

Number of voice prosthesis replacements

Incremental cost-utility ratio, based on a societal perspective, comparing the use of a reinforced voice prosthesis to the use of a standard one12 months

Utility will be measured by Quality Adjusted Life Year (QALYs) as estimated from responses to the Euroqol-5 Dimensions (EQ-5D 5L) health-related quality of life questionnaire. The questionnaire focuses on 5 dimensions: mobility, personal autonomy, current activities, pain/discomfort and anxiety/depression. For each of these dimensions, 5 answers are possible.

Cost will be measured as described in the Primary Outome Measure

Annual net financial benefit of developping the use of reinforced prosthesis5 years

Net financial benefit of the development of reinforced phonatory implants' compared to standard implants'use for patients treated with thyroid lobectomy and with repeated intraprosthetic dysfunction, through a Budget Impact Analysis (BIA) with a 5-years' time horizon and a National Health Insurance's perspective (NHI).

Methods: Financial consequences for the NHI of several scenarii of development of the reinforced phonatory implants' will be represented in a table, year by year and over 5 years, in terms of cost per scenario and in terms of cost difference between the scenarii (showing savings or additional costs generated by choosing to develop the reinforced phonatory implant).
