Trial Outcomes & Findings for Vaccination Education Through Pharmacists and Senior Centers (VEPSC) (NCT NCT03239665)

NCT ID: NCT03239665

Last Updated: 2020-07-01

Results Overview

Knowledge and awareness about the target vaccine-preventable diseases was assessed at each timepoint using the VEPSC Knowledge Instrument, a 3-section, 22-item instrument categorical response instrument. Scores consist of number of correct responses to the questions on the knowledge instrument, thus a higher score indicates better performance. Four scores are possible: three disease-specific subscores (one each for pneumonia, influenza, and zoster) and one total score (equaling the sum of the three disease-specific subscores). Possible score ranges are as follows: pneumonia 0-7; influenza 0-7; zoster 0-8; total 0-22. For each score type, pairwise score differences were calculated between all 3 timepoints (baseline, post-test, and one-month follow-up). Positive values indicate increased knowledge among participants; negative values indicate decreased knowledge.

Pharmacist-led Intervention (PHARM)
In the PHARM intervention group, participants will be given a 60-minute formal presentation on vaccine-preventable diseases to address knowledge and beliefs related to zoster, pneumonia, and influenza and to address barriers to receiving vaccination. In several studies, it has been demonstrated that those who believe it is wise to receive vaccinations and those that have discussed vaccination with their healthcare provider are more likely to receive a vaccine. Pharmacist-led Intervention (PHARM): 60 minute didactic lecture about vaccinations.
Peer-led Intervention (PEER)
A pharmacist will train the peer educators about vaccine-preventable diseases over the course of two didactic sessions. Following this training, a third session will be held to train the peer educators on the script that they will deliver to participants. The script will include the key learning points to be taught by the peer educators to participants about vaccine preventable diseases and vaccination. The script will also include role-play exercises. In the role-play exercises, 3 vaccination-related scenarios (one for each disease- zoster, pneumonia, and influenza) will be delivered to illustrate situations participants might encounter when interacting with healthcare providers or friends/family. Peer-led Intervention (PEER): 60 minute peer led small group intervention including skits and other educational material

SECONDARY outcome

Timeframe: Measured at baseline (BL), immediately post-intervention (PT), and 1 month follow-up (1M)

Beliefs about vaccine-preventable diseases and vaccination were assessed via agreement with 5 statements scored on a 4-point Likert scale (1-Completely disagree, 2-Somewhat disagree, 3-Somewhat agree, 4-Completely agree) at each timepoint. The changes in beliefs between baseline, post-intervention, and the one-month follow-up were assessed in both PHARM and PEER groups. Pairwise Wilcoxon Signed-Rank tests were run comparing within-group changes in beliefs across timepoints and applying the Bonferroni correction (α=0.05/3=0.0167).

SECONDARY outcome

Timeframe: Measured after completion of all programs in both groups (an average of one year).

Measure the program costs of PHARM and PEER from the senior center perspective. Costs were measured in total for each group, and per-participant costs were calculated by dividing total group cost by group sample size. Outcome measure type is thus reported as "number" rather than choosing measures of central tendency and dispersion/precision (i.e., there are no standard deviations, confidence intervals, or ranges with this methodology).

Pharmacist-led Intervention (PHARM)
n=147 Participants
In the PHARM intervention group, participants will be given a 60-minute formal presentation on vaccine-preventable diseases to address knowledge and beliefs related to zoster, pneumonia, and influenza and to address barriers to receiving vaccination. In several studies, it has been demonstrated that those who believe it is wise to receive vaccinations and those that have discussed vaccination with their healthcare provider are more likely to receive a vaccine. Pharmacist-led Intervention (PHARM): 60 minute didactic lecture about vaccinations.
Peer-led Intervention (PEER)
n=140 Participants
A pharmacist will train the peer educators about vaccine-preventable diseases over the course of two didactic sessions. Following this training, a third session will be held to train the peer educators on the script that they will deliver to participants. The script will include the key learning points to be taught by the peer educators to participants about vaccine preventable diseases and vaccination. The script will also include role-play exercises. In the role-play exercises, 3 vaccination-related scenarios (one for each disease- zoster, pneumonia, and influenza) will be delivered to illustrate situations participants might encounter when interacting with healthcare providers or friends/family. Peer-led Intervention (PEER): 60 minute peer led small group intervention including skits and other educational material

SECONDARY outcome

Timeframe: Measured immediately post-intervention (PT) and at 1 month follow-up (1M)

Satisfaction was assessed on the post-intervention and one-month follow-up surveys using two statements that were each scored on a 4-point Likert scale (1-Completely disagree, 2-Somewhat disagree, 3-Somewhat agree, 4-Completely agree). The statements were: 1) "The educational program kept me interested or engaged" and 2) "I was satisfied with the content of the educational program". At each timepoint, responses were dichotomized as "agree" (comprising the "Somewhat agree" and "Completely agree" response options) and "disagree" (comprising the "Somewhat disagree" and "Completely disagree" response options), and these dichotomous responses were compared between PHARM and PEER via Fisher's exact test.

Pharmacist-led Intervention (PHARM)
n=147 Participants
In the PHARM intervention group, participants will be given a 60-minute formal presentation on vaccine-preventable diseases to address knowledge and beliefs related to zoster, pneumonia, and influenza and to address barriers to receiving vaccination. In several studies, it has been demonstrated that those who believe it is wise to receive vaccinations and those that have discussed vaccination with their healthcare provider are more likely to receive a vaccine. Pharmacist-led Intervention (PHARM): 60 minute didactic lecture about vaccinations.
Peer-led Intervention (PEER)
n=140 Participants
A pharmacist will train the peer educators about vaccine-preventable diseases over the course of two didactic sessions. Following this training, a third session will be held to train the peer educators on the script that they will deliver to participants. The script will include the key learning points to be taught by the peer educators to participants about vaccine preventable diseases and vaccination. The script will also include role-play exercises. In the role-play exercises, 3 vaccination-related scenarios (one for each disease- zoster, pneumonia, and influenza) will be delivered to illustrate situations participants might encounter when interacting with healthcare providers or friends/family. Peer-led Intervention (PEER): 60 minute peer led small group intervention including skits and other educational material
