About this study

The purpose of this study is to determine if a multimodal immunization program carried out in obstetrics and gynecology (ob/gyn) practices would be more effective in improving ob/gyn patients' immunization rates, specifically for Tdap (Tetanus, Diphtheria, Pertussis), HPV (Human papilloma virus), and influenza vaccines, than the usual care provided to patients in ob/gyn practices.

Multimodal Vaccine Program

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Multimodal Vaccine ProgramBehavioural

    Efforts will be made to collaborate with private ob/gyn offices to develop a multimodal intervention to improve patients'immunization rates. As part of the overall intervention, intervention practices will agree to 1) purchase, stock, and administer influenza, HPV, and Tdap vaccines, if not already doing so and 2) track patients' vaccination status. In addition, intervention strategies adopted by intervention settings to improve immunization rates may include:

    • Patient education regarding the importance of vaccination, including encouragement of vaccination for family members
    • Practice-based reminder/recall
    • Seek to decrease missed opportunities for immunization by using either or both of the following: provider prompts and/or provider education and feedback

What is being measured

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

  1. Change in the percent of women vaccinated with one or more Tdap vaccines (among eligible patients) in intervention settings compared to control settings.

    The percent of eligible patients presenting for care who receive Tdap vaccine will be assessed one year prior to the intervention and 12 and 21 months after the intervention. This assessment will occur in both intervention and control settings using two data sources 1) administrative data and 2) patient self-report of vaccine history.

    Measured: 1 year (administrative data) & 2 months (survey data) prior to intervention & 12 and 21 months after intervention (administrative and survey data)

  2. Change in the percent of women vaccinated with influenza vaccine (among eligible patients) in intervention settings compared to control settings.

    The percent of eligible patients presenting for care who receive influenza vaccine will be assessed one year prior to the intervention and at 12 and 21 months after the intervention. This will be assessed in both intervention and control settings using two data sources 1) administrative data and 2) patient self-report of vaccine history.

    Measured: 1 year (administrative data) & 2 months (survey data) prior to intervention & 12 and 21 months after intervention (administrative and survey data)

  3. Change in the percent of women who have initiated the HPV vaccine series (among eligible patients) in intervention settings compared to control settings.

    The percent of eligible patients presenting for care who have received one or more HPV vaccines will be assessed one year prior to the intervention and at 12 and 21 months after the intervention. This number will be assess in both intervention and control settings using two data sources 1) administrative data and 2) patient self-report of vaccine history.

    Measured: 1 year (administrative data) & 2 months (survey data) prior to intervention & 12 and 21 months after intervention (administrative and survey data)

  4. Change in the percent of women who have received one or more needed vaccines (eligible patients who receive HPV, influenza, and/or Tdap vaccines) in intervention settings compared to control settings.

    The percent of eligible patients presenting for care who have received one or more needed vaccines (HPV, Tdap, and/or influenza vaccines) will be assessed one year prior to the intervention and at 12 and 21 months after the intervention. This number will be assess in both intervention and control settings using two data sources 1) administrative data and 2) patient self-report of vaccine history.

    Measured: 1 year (administrative data) & 2 months (survey data) prior to intervention & at 12 and 21 months after intervention (administrative and survey data)

Secondary outcomes (3)
  1. Change in the percent of women who have completed the HPV vaccine series (among eligible patients) in intervention settings compared to control settings.

    The percent of eligible patients presenting for care who have completed the HPV vaccine series will be assessed one year prior to the intervention and at 12 and 21 months after the intervention. This number will be assess for both intervention and control settings using two data sources 1) administrative data and 2) patient self-report of vaccine history.

    Measured: 1 year (administrative data) & 2 months (survey data) prior to intervention & at 12 and 21 months after intervention (administrative and survey data)

  2. Change in the percent of women who report Tdap vaccine uptake among individuals in frequent contact with their infant in intervention offices compared to control offices

    The percent of patients who report one or more individuals who are/will be in frequent contact with their infant having received Tdap vaccine will be assessed during Feb/March 2013 and Feb/March 2014. These data will be collected in patients of both intervention and control settings via on-line survey and be administered to patients who volunteer to take the survey.

    Measured: Feb/March 2013 & Feb/March 2014

  3. Change in the percent of women who report influenza vaccine uptake among individuals in frequent contact with their infant in intervention offices. compared to control offices

    The percent of patients who report one or more individuals who are/will be in frequent contact with their infant having received influenza vaccine will be assessed during Feb/March 2013 and Feb/March 2014. These data will be collected in patients of both intervention and control settings via on-line survey and be administered to patients who volunteer to take the survey.

    Measured: Feb/March 2013 & Feb/March 2014
