About this study

Official title: Pertussis Vaccination in Pregnant Women: Implementation and Evaluation of Different Models of Vaccination Dispensation

Brief Summary: The study compares four models of pertussis vaccination dispensation to pregnant women on the vaccine coverage obtained. In addition, the cost of the different models of vaccination will be evaluated.

Read the detailed description

This is a quasi-experimental study with a non-equivalent control group in pregnant women, taking place in 4 regions of Québec (Montréal, Montérégie, Capitale-Nationale, Mauricie). Four models of vaccine dispensation will be evaluated: one university hospital around gestational diabetes screening, local health and social services centres (CSLC) and a high volume clinic. 250 participants will be recruited in each of the four types of centres.

In addition, the study will also evaluate the costs incurred by all those involved in the pertussis vaccination program for pregnant women as well as the cost per woman vaccinated.

Health Professionals:

15 to 20 health professionals involved in providing immunization services to pregnant women: obsterician-gynaecologists, family doctors and nurses in participating clinics will be interviewed to evaluate their knowledge, attitudes and professional practises regarding pertussis vaccination during pregnancy.

Evaluating the Cost:

A detailed costing approach (micro-costing) will be used. Time and movement will be studied by direct observation using a grid on an electronic file in each of the 5 environments studied in order to identify the services and activities carried out as well as to determine the resources involved in the implementation of these services and activities. Three typical vaccination days will be chosen to make these observations, in each of the four study environments.

The main activities observed will be related to preparations for vaccination up to the vaccination itself (informed consent, injection, etc.), the capture of vaccination data the management of vaccines and equipment, clinical manifestations, etc. If necessary, the people observed can be interviewed directly to better understand the activities or services provided. Otherwise, some questions may be included in the interviews described above.

The major cost categories that will be evaluated for each of the delivery modalities are human resources and supplies. The cost components listed are: nursing time (immunization / training), coordination time, support staff time, office supplies, vaccine storage equipment, vaccine transportation equipment, vaccine transportation, health and safety equipment, emergency, single-use vaccination equipment and others.

With regard to the costs borne by women, the main categories of variables evaluated will be: the time spent making appointments and attending vaccination appointments, working time lost, if any, transportation, childcare and other expenses

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Proportion of pregnant women vaccinated against pertussis

    Proportion of pregnant women vaccinated against pertussis will be evaluated in 5 Quebec regions

    Measured: 11 months, May 2019 o March 2020

  2. Proportion of pregnant women who consider pertussis as serious risk for infant

    Understanding of pertussis risk

    Measured: 12 months, May 2019 to April 2020

  3. Proportion of pregnant women who consider pertussis vaccination during pregnancy as safe.

    Understanding of vaccine risk perception in pregnant women

    Measured: 12 months, May 2019 to April 2020

  4. Costs for each vaccinated woman

    The cost of vaccination will be evaluated and compared between the four vaccination models.

    Measured: 12 months, January to December 2019

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Boostrix administered during gestational diabetes screening and Boostrix administered in high volume obstetric clinic in people with Pertussis, run by St. Justine's Hospital at 3 sites in Canada.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 24 Sep 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in Canada. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Proportion of pregnant women vaccinated against pertussis (time frame: 11 months, May 2019 o March 2020). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Sep 2021.
