About this study

Official title: A Vaccination SOP Toolkit in Diverse Practices Implemented & Tested With RE-AIM

The purpose of this study is to test whether or not the 4 Pillars Toolkit increases adult Influenza, pneumococcal polysaccharide vaccine (PPSV), tetanus, adult diphtheria and acellular pertussis vaccine (Tdap/Td) vaccination rates. The vaccines are all FDA licensed vaccines and to be used according to national guidelines. The investigators will conduct a randomized cluster trial of this toolkit in diverse primary care practice with electronic medical records (EMRs).

Read the detailed description

This intervention is a two-region, two-year, stratified randomized cluster trial in 24 primary care practices with EMRs. These practices will be randomly assigned to be intervention or control sites to test this 4 Pillars Toolkit intervention package of evidence-based techniques tailored to their practice structure and culture; one set of practices randomized to intervention in year 1 and the other to control. In year 2, the other set of practices will receive the intervention and community controls may be sought.

These diverse practices consist of: 18 diverse practices from UPMC in western Pennsylvania and 6 diverse practices from large community health centers in a PBRN in Texas.

Conditions: Adult Influenza Vaccinations, Adult PPSV Vaccinations, Adult Tdap/Td Vaccinations
Being tested: Pillar 1: Convenient Vaccination Services, Pillar 2: Patient notification, Pillar 3: Enhanced Office Systems, Pillar 4: Motivation
Keywords: influenza vaccine, PPSV, Tdap, vaccination, adult
Medical subject headings: Influenza, Human

What participants receive

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

Pillar 1: Convenient Vaccination ServicesBehavioural
Extend Vaccination Season: Begin vaccinating for influenza as soon as vaccine arrives; use every visit as opportunity to vaccinate; extend the season for influenza by vaccinating in January and beyond.
Use Express Vaccination services such as influenza vaccination clinics, Open access vaccine scheduling (for all vaccines), or dedicated vaccination station. When giving influenza vaccination, screen for need for PPSV/Tdap.
Pillar 2: Patient notificationBehavioural
Patient Education: notifying patients of doctor recommendations for vaccination; providing information on express vaccination services via email, autodialer, "on-hold" messages, clinic websites, and/or social media
Pillar 3: Enhanced Office SystemsBehavioural
Routine assessment for office systems flow to ensure staff consistently promoting vaccination: utilization of EMR prompts, review of Immunization tabs within EMR, and/or checking vaccination status as part of vital signs when rooming. Empower staff to vaccinate by use of a standing orders program (SOP). Order a sufficient supply of vaccination to cover increased rates
Pillar 4: MotivationBehavioural
Utilization of an Office Immunization Champion who will track overall progress towards their goal - setting a goal of increased rates of 20 to 25% for influenza vaccine; monitoring and sharing progress with staff regularly; and changing office systems flow as needed to increased vaccination rates.

Receives: Behavioral: Pillar 1: Convenient Vaccination Services; Behavioral: Pillar 2: Patient notification; Behavioral: Pillar 3: Enhanced Office Systems; Behavioral: Pillar 4: Motivation
12 clinical practices (control sites)	No intervention	12 diverse clinical practices will receive no additional assistance in Year 1 to increase their adult influenza, PPSV, Tdap/Td vaccination rates, they will follow guidelines for usual care. In Year 2 however they will become intervention sites and receive the 4 Pillars Toolkit for use in increasing vaccination rates

Questions about this trial

What is this clinical trial studying?

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 7 inclusion and 4 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 6 Oct 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. 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.

Are results available for this study?

Yes. Results are posted in the registry (first posted 2 Oct 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Year 1 RCCT: Change From Baseline in the Percentage of Participants Who Were Vaccinated at the End of Year 1 (time frame: % vaccinated by 5/31/2014 (Tdap, Pneumococcal); % vaccinated by 1/31/2014 (Influenza)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01868334, which also lists 3 linked publications.

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 6 Oct 2023.
