Evaluation of Dental Emergency Treatments During COVID19 Crisis

"I. Research progress Two investigators will take turns in the service for the search duration. They will be responsible for informing patients of the research upon their arrival in the service and for the data collection and telephone follow-ups.

The course of the research will take place as follows:

Day of consultation (D0):

• Patient information on the search when he arrives in the service; explanation of its objectives, its modalities and constraints.
• Verification of eligibility criteria.
• Collection of the patient's non-opposition by the dentist during the consultation
• Consultation according to the usual care. During this procedure, the practitioner performs a medical history and, according to the patient's answers, completes the ""General Information Questionnaire"".

He carries out the emergency care and explains the postoperative consequences.

• Patient filling in the satisfaction questionnaire immediately after consultation.

Telephone follow-up:

• Telephone follow-up by the interviewer and fill in the questionnaire - in case of non-availability of the patient on day 1, the patient will be recalled on day 2 and the extrapolated data on the slope of the curve between D1 and D2
• Telephone follow-up by the interviewer on the day and filling in the questionnaire - if the patient is not available on day 3, the patient will be recalled on day 4 and the data extrapolated according to the slope of the curve between D1 and D4; if the patient is not available at D4, he will be recalled to D5 and the extrapolated data between D1 and D5.
• Telephone follow-up on the interviewer's day and fill in the questionnaire in case of non-availability of the patient on day 7, the patient will be recalled to D8 and the data extrapolated according to the slope of the curve between D3 and D8; if the patient is still not available on D8, he will be recalled to D9 and the extrapolated data between D3 and D9.

For the night sample : from 6:30 pm to 8 am Recall should be 24 hours after the care, but it seems not ethical or efficient to recall patients the night following ; an extension of 12 hours will be instaured, taking then the recalls to 36h (D1), 84h (D3), and 180h (D7) after the care.

For the Day sample : from 8 am to 6:30 pm D1: 24 hours after the care D3: 72 hours after the care D7 :168 hours after the care

II.1.STATISTICAL ASPECTS

II.1. Statistical justification for the sample size The investigators want to assess the activity of the service over 4 weeks during the COVID crisis by taking two readings per week during the day and one during the night. The 1st figures of the service (week of March 16 to 22) indicate an average attendance of 80 patients day and 50 per night.

So the investigators will have 8 x 80 = 640 patients during the day period and 4x 50 = 200 patients per night According to a previous study in the department (15), 50% of patients in care could not be included in the study or were lost to follow-up.

This leads to a number of 420 analysable patients per week.

II.2. Description of statistical methods A descriptive analysis of the characteristics of the sample will be performed (age, sex, reason for consultation, diagnosis, prior appointment test, average score of anxiety and pain scores on D0, D1, D3, D7, compliance with instructions and making follow-up appointments,), satisfaction rating, appreciation of the quality of medical care, politeness of staff, waiting time, assessment of the quality of the care setting, the information received, the treatment received, and the recommendation of the service to third parties will be made.

An analysis of the evolution of pain and anxiety scores between D0, D1, D3 and D7 will be performed.

Correlations between the type of treatment and the perceived pain as well as the type of treatment and the perceived anxiety will be made.

II.3. Method of taking into account missing or invalid data Patients unreachable during the telephone follow-up period will be contacted the next day; the pain and anxiety scores will then be extrapolated from the previous data and the new data collected, by calculating the nearest point on the curve connecting these two data. If they are new unreachable, the data will be considered missing. Data from patients with missing data will be analyzed separately.

III. DATA MANAGEMENT

III.1. Terms of data collection The research does not foresee the use of data extracted from existing information systems or from previously completed studies.

No nominative data will be collected as part of this research. The data will be rendered non-identifying. They must not in any case show in clear the names of the persons concerned or their address.

As part of this research, topics will be identified as follows:

N or W (depending on the Night or Week-end sample) - Chronological order of the person (3 digits) - first letter of the first name - first letter of last name

The answers to the different questionnaires (completed by the patients and the interviewers) will be entered into an EXCEL file. This file will be protected by a password.

The seizure will be carried out by the coordinating investigator or one of those collaborators (dentist or student) declared in the center and trained in research at the end of each session.

III.2. Data circuit The investigators will collect the data directly from the patient during the consultation or during telephone interviews on paper forms (CRF).

This data will then be entered into an Excel database specifically created for the search.

The database will be kept on the computer of the odontology service at the Pitié-Salpêtrière hospital and will be protected by a password known only to research stakeholders.

Data analysis will be done by the principal investigator and the research stakeholders"
