Brief summary
This study will assess the efficacy, adoption, and impact of an integrated intervention to improve adherence to recommended stomach cancer prevention guidelines (H. pylori test-and-treat) for at-risk Chinese Americans in NYC. The integrated multifaceted theory-based intervention involves: 1) a health systems-level intervention using electronic health record (EHR)-based tools to facilitate H. pylori test-and-treat strategies; and 2) a community-engaged culturally and linguistically adapted CHW-led patient navigation program we are currently pilot testing for feasibility and acceptability. Using a 2-arm randomized controlled trial (RCT) design, \> 144 Chinese American patients across NYC safety net hospital endoscopy clinics and primary health centers will participate.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Number of Participants With Eradication of H. Pylori (ITT) | Up to Month 3-Post Treatment | Measured using breath ammonia measurement, fecal stool antigen test or other clinically approved H. pylori infection diagnostic test. Data extracted from patient EHR. Includes positive results for those with self-reported or missing results. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in Ottawa Decision Self-Efficacy Scale Score From Baseline to 6 Months | Baseline, Month 6 | Participants completed the Ottawa Decision Self-Efficacy Scale, which assessed participants' confidence in making an informed choice, at baseline and 6-month follow-up. The scale consists of 11 questions on a 5-point Likert scale from 0 (not at all confident) to 4 (very confident). The raw score is the sum of responses. The raw score is converted to a standardized total score that ranges from 0 to 100; higher total scores indicate greater decision self-efficacy. |
| Change in Medication Adherence Report Scale (MARS-5) Score From Baseline to Month 6 | Baseline, Month 6 | Participants completed the MARS-5 self-assessment of medication adherence at baseline and 6-month follow-up. One item assessed unintentional non-adherence, while four items assessed intentional non-adherence. Participants indicated how often each statement applied to them in the past month on a 5-point Likert scale (1=always, 2=often, 3=sometimes, 4=rarely, 5=never), resulting in a total score ranging from 5 to 25. Adherence is defined as a score of 25. |
| Change in Stomach Cancer Knowledge Between Baseline and 6-months | Baseline, Month 6 | Participants were asked about associations with the risk of getting stomach cancer (alcohol, spicy food, stress, family history, h. pylori infection, smoking, salty food, being physically inactive, pickled food, food high in sugar). True or false was chosen. Variables were recoded to correct (1) and incorrect (0), and summed for a final score (0-10, 10=highest knowledge) |
| Number of Participants With Eradication of H. Pylori (Clinically Confirmed) | Up to Month 3-Post Treatment | Measured using breath ammonia measurement, fecal stool antigen test or other clinically approved H. pylori infection diagnostic test. Data extracted from patient EHR. |
| Change in PROMIS Global Physical Health T-Score Between Baseline and 6-months | Baseline, Month 6 | Participants completed the PROMIS Global Physical Health Scale, which assessed participants' physical health, at baseline and 6-month follow-up. Four questions assessed global physical health. Three questions were administered using five-category response scales, and one item used a response scale of 0-10 that was recoded to five categories. Responses are recoded into t-scores, which rescales the raw sum score into a standardized score from 0-100, with a mean of 50 and a standard deviation of 10. Higher scores indicate more of the concept being measured. |
| Change in PROMIS Global Mental Health T-Score Between Baseline and 6-months | Baseline, Month 6 | Participants completed the PROMIS Global Mental Health Scale, which assessed participants' mental health, at baseline and 6-month follow-up. Four questions assessed global mental health, and all were administered using five-category response scales. Responses are recoded into t-scores, which rescales the raw sum score into a standardized score from 0-100, with a mean of 50 and a standard deviation of 10. Higher scores indicate more of the concept being measured. |
| Change in H. Pylori Knowledge Between Baseline and 6-months | Baseline, Month 6 | Participants were asked about associations with h. pylori (blood, untreated/contaminated water, rats, mosquitoes, contaminated food, vomit, poor sanitation). True or false was chosen. Variables were recoded to correct (1) and incorrect (0), and summed for a final score (0-7, 7=highest knowledge) |
