A Research Protocol to Test the Effectiveness of Text Messaging and Reminder Calls to Increase Service Use Referrals in a Community Engagement Program

The HealthStreet Cancer Survivor Cohort: a Community Registry for Cancer Research

PURPOSE

This report describes a cancer survivor cohort from a community engagement program and compares characteristics and willingness to participate in health research between the cancer survivors and non-cancer community members.

METHODS

Among 11,857 members enrolled in HealthStreet at the University of Florida (10/2011-03/2020), 991 cancer survivors were identified and 1:1 matched to control members without cancer on sex, age, and zip code. Demographics, body weight, height, social determinants of health, history of cancer, and willingness to participate in research were recorded by Community Health Workers as a part of the baseline Health Needs Assessment.

RESULTS

Among the cancer survivors, 71.6% were female and 19.2% lived in rural areas with a mean age of 56.7 years in females and 60.8 years in males. At baseline, 44.7% received a cancer diagnosis within 5 years, while 15.8%, more than 20 years. Cancer survivors (vs. matched non-cancer controls) were less likely to be Black (31.1% vs. 63.6%) but more likely to be divorced, separated, or widowed (49.5% vs. 41.2%), be normal/underweight (34.0% vs. 25.6%) and have health insurance (80.0% vs. 68.6%; all p < 0.05). Cancer survivors versus matched controls reported higher rates of ever being in a health research study (32.4% vs. 24.9%) and interest in participating in studies ranging from minimal risk to greater-than-minimal risk.

CONCLUSIONS

Cancer survivors from this community engagement program agnostic to cancer types and treatment are diverse in geography, race, and social determinants of health and can be a valuable resource for observational, interventional, and biospecimen research in cancer survivorship.

An Interactive Text Message Survey as a Novel Assessment for Bedtime Routines in Public Health Research: Observational Study

BACKGROUND

Traditional research approaches, especially questionnaires and paper-based assessments, limit in-depth understanding of the fluid dynamic processes associated with child well-being and development. This includes bedtime routine activities such as toothbrushing and reading a book before bed. The increase in innovative digital technologies alongside greater use and familiarity among the public creates unique opportunities to use these technical developments in research.

OBJECTIVE

This study aimed to (1) examine the best way of assessing bedtime routines in families and develop an automated, interactive, text message survey assessment delivered directly to participants' mobile phones and (2) test the assessment within a predominately deprived sociodemographic sample to explore retention, uptake, feedback, and effectiveness.

METHODS

A public and patient involvement project showed clear preference for interactive text surveys regarding bedtime routines. The developed interactive text survey included questions on bedtime routine activities and was delivered for seven consecutive nights to participating parents' mobile phones. A total of 200 parents participated. Apart from the completion of the text survey, feedback was provided by participants, and data on response, completion, and retention rates were captured.

RESULTS

There was a high retention rate (185/200, 92.5%), and the response rate was high (160/185, 86.5%). In total, 114 participants provided anonymized feedback. Only a small percentage (5/114, 4.4%) of participants reported problems associated with completing the assessment. The majority (99/114, 86.8%) of participants enjoyed their participation in the study, with an average satisfaction score of 4.6 out of 5.

CONCLUSIONS

This study demonstrated the potential of deploying SMS text message-based surveys to capture and quantify real-time information on recurrent dynamic processes in public health research. Changes and adaptations based on recommendations are crucial next steps in further exploring the diagnostic and potential intervention properties of text survey and text messaging approaches.

Factors influencing attrition in 35 Alzheimer's Disease Centers across the USA: a longitudinal examination of the National Alzheimer's Coordinating Center's Uniform Data Set

OBJECTIVE

A lack of understanding of the causes of attrition in longitudinal studies of older adults may lead to higher attrition rates and bias longitudinal study results. In longitudinal epidemiological studies of Alzheimer's disease and related dementias, high rates of attrition may cause a systematic underestimation of dementia prevalence and skew the characterization of the disease. This can compromise the generalizability of the study results and any inferences based on the surviving sample may grossly misrepresent the importance of the risk factors for dementia. The National Institute on Aging outlined a National Strategy for Recruitment and Participation in Alzheimer's Disease Clinical Research to address this problem, providing evidence of the magnitude of this problem.

METHOD

To explore predictors of attrition, this study examined the National Alzheimer's Coordinating Center (NACC) Uniform Data Set, a repository of observations of older adults spanning 11 years, using survival analysis. Four samples were examined: the full sample (n = 30,433), the alive subsample excluding those who died (n = 24,231), the MRI sample [participants with complete MRI data (n = 1104)], and the alive MRI subsample [participants with MRI data excluding those who died (n = 947)].

RESULTS

Worsening cognitive impairment, neuropsychiatric symptoms, and difficulty with functional activities predicted attrition, as did lower hippocampal volume in the MRI subsample. Questionable co-participant reliability and an informant other than a spouse also increased risk of attrition.

DISCUSSION

Special considerations exist in recruiting and retaining older adults in longitudinal studies, and results of baseline psychological, functional, and cognitive functioning should be used to identify targeted retention strategies.

Coverage and predictors of influenza vaccination in patients with cystic fibrosis in a campaign with a mobile phone text messaging intervention

Annual influenza vaccination is considered the best protection against influenza infection. We analyzed the influenza vaccine coverage (IVC) in cystic fibrosis (CF) patients and evaluated the factors associated with the IVC, including the effect of text-message/SMS reminders.

We performed a cross-sectional study in the Community of Madrid (Spain) in 2015. The target population was people with CF older than 6 months of age at the beginning of the flu vaccination campaign. The IVC was calculated according to the study variables.

A total of 445 CF patients were analyzed. In 2015, IVC reached 67.9% and was higher in children and women. The main factor associated with flu vaccination was having been vaccinated in the previous campaign (aOR 14.36; IC95%: 8.48–24.32).

The probability of being vaccinated after receiving the SMS was more than twice than for those who did not receive it, although no statistical significance was reached.

In conclusion the IVC of patients with CF is high, but it still has room for improvement. SMS reminders sent to CF patients might improve influenza vaccine uptake.

Approaching Retention within the ABCD Study

Retention efforts are critical to maintain relationships with research participants over time. This is especially important for the Adolescent Brain Cognitive Development (ABCD) study, where families are asked to stay engaged with the study throughout the course of 10 years. This high-degree of involvement is essential to longitudinally track child and adolescent development. At a minimum, we will connect with families every 6 months by telephone, and every year in person, with closer contact with the youth directly as they transition into adolescence. Differential retention, when related to non-random issues pertaining to demographic or risk features, can negatively impact the generalizability of study outcomes. Thus, to ensure high rates of retention for all participants, the ABCD study employs a number of efforts to support youth and families. This overview details the framework and concrete steps for retention.
