Too much contact

The Goldilocks Quandary Too Little High
5
Overview Cancer registry research policies The sample The analysis (models and methods) The results The grand finale- o How much contact is just right?
6
Recruitment through US Cancer Registries 1. Researcher initiates contact with patient 2. Registry initiates contact with patient Opt-out approach Opt-in approach 3.Physician notification required Beskow, L. M., R. S. Sandler and M. Weinberger (2006). "Research recruitment through US central cancer registries: balancing privacy and scientific issues." Am J Public Health 96(11): 1920-1926.

Sample Patients contacted Jan. 2007-Oct. 2012 11 studies Excludes : Deceased patients/next-of-kin studies “Lost” patients Ineligible patients 9,488 patients 75% permission studies 25% consent studies

9
Analysis Bi-variate analyses using chi-square and ANOVA (p value <0.05) Multinomial logistic regression models o 3 models: Everyone (excluding site) & by sex (including site)
10
Regression Models Outcome: Response to contact effort –Categorical: yes, no, nonresponsive Predictors: Sex Age at Diagnosis Site Age at Contact Stage Time from diagnosis to first contact attempt

All Contact Attempts
20
Contact Attempts by Response
21
Contact Attempts
25
Conclusions Only men get prostate cancer After 8 contact attempts 95% of those who will respond, have responded As age increases, refusals increase and nonresponders decrease Younger ages were more likely to be nonresponders
26
Limitations Contact protocol varied by study Consent studies lack diversity Population lacks diversity Geography and SES Generalizability –Limited sites considered –Are Utahns more willing to participate? Simmons, R.G., A.L. Yuan-Chin, et al. (2013). “Examining the challenges of family recruitment to behavioral intervention trials…” Trials 14:116
27
Future Research & Considerations Adjust contact effort based on target population Additional analysis with a diverse population including additional variables Examine relationship between registry policies, participation rates, and study’s response rate –Simmons, R.G., A.L. Yuan-Chin, et al. (2013). “Examining the challenges of family recruitment to behavioral intervention trials…” Trials 14:116
