Protocol for the ONLOOP trial: pragmatic randomized trial evaluating a province-wide system of personalized reminders for evidence-based surveillance tests in adult survivors of childhood cancer in Ontario. Implement Sci 2024; 19:19. [PMID: 38395903 PMCID: PMC10885391 DOI: 10.1186/s13012-024-01347-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2023] [Accepted: 01/29/2024] [Indexed: 02/25/2024] Open
Abstract
BACKGROUND Childhood cancer treatment while often curative, leads to elevated risks of morbidity and mortality. Survivors require lifelong periodic surveillance for late effects of treatment, yet adherence to guideline-recommended tests is suboptimal. We created ONLOOP to provide adult survivors of childhood cancer with detailed health information, including summaries of their childhood cancer treatment and recommended surveillance tests for early detection of cardiomyopathy, breast cancer, and/or colorectal cancer, with personalized reminders over time. METHODS This is an individually randomized, registry-based pragmatic trial with an embedded process and economic evaluation to understand ONLOOP's impact and whether it can be readily implemented at scale. All adult survivors of childhood cancer in Ontario overdue for guideline-recommended tests will be randomly assigned to one of two arms: (1) intervention or (2) delayed intervention. A letter of information and invitation will detail the ONLOOP program. Those who sign up will receive a personalized toolkit and a screening reminder 6 months later. With the participants' consent, ONLOOP will also send their primary care clinician a letter detailing the recommended tests and a reminder 6 months later. The primary outcome will be the proportion of survivors who complete one or more of the guideline-recommended cardiac, breast, or colon surveillance tests during the 12 months after randomization. Data will be obtained from administrative databases. The intent-to-treat principle will be followed. Based on our analyses of administrative data, we anticipate allocating at least 862 individuals to each trial arm, providing 90% power to detect an absolute increase of 6% in targeted surveillance tests completed. We will interview childhood cancer survivors and family physicians in an embedded process evaluation to examine why and how ONLOOP achieved success or failed. A cost-effectiveness evaluation will be performed. DISCUSSION The results of this study will determine if ONLOOP is effective at helping adult survivors of childhood cancer complete their recommended surveillance tests. This study will also inform ongoing provincial programs for this high-risk population. TRIAL REGISTRATION ClinicalTrials.gov NCT05832138.

Exploring Barriers and Facilitators to Indirect Cascade Screening for Familial Hypercholesteraemia in a Paediatric/Parent Population. CJC PEDIATRIC AND CONGENITAL HEART DISEASE 2023; 2:211-218. [PMID: 37970213 PMCID: PMC10642093 DOI: 10.1016/j.cjcpc.2023.05.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/25/2023] [Accepted: 05/23/2023] [Indexed: 11/17/2023]
Abstract
Background Familial hypercholesteraemia (FH), an inherited disorder of cholesterol metabolism, has a prevalence of 1:250 and an associated 6- to 22-fold increased risk for cardiovascular disease. Despite the prevalence and availability of effective risk-reduction treatments, 90% of at-risk Canadians are undiagnosed. Indirect cascade screening from an index case is useful but the uptake is low (<4%), suggesting that barriers may exist. Using the Theoretical Domains Framework, we sought to determine barriers and facilitators among parents of children diagnosed with FH that may influence the uptake of cascade screening among families. Methods A qualitative description approach was used for virtual interviews with 10 parents of children with FH, recruited from a regional Lipid Clinic in Toronto, Canada. Semistructured interviews were conducted. The data were analysed using a directed content analysis method. Results Five interconnecting themes were identified that captured both facilitators and barriers of indirect cascade screening: a high level of knowledge about FH after clinic attendance; parents' surprise of their child's diagnosis and ongoing worry; parents' willingness to communicate the need for cholesterol screening; parents' desire for educational materials, dictated by an external vs internal locus of control; and social and societal influences including the lack of awareness about FH in professional and public domains. Conclusions The themes identified will inform next steps in programme development. An urgent need was identified for strategies to educate the public and primary care providers about FH and blood cholesterol/genetic screening.

JMIR Hum Factors 2022; 9:e37606. [PMID: 36099013 PMCID: PMC9516377 DOI: 10.2196/37606] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2022] [Revised: 06/21/2022] [Accepted: 07/18/2022] [Indexed: 11/13/2022] Open
Abstract
Background Survivors of childhood cancer are at lifelong risk of morbidity (such as new cancers or heart failure) and premature mortality due to their cancer treatment. These are termed late effects. Therefore, they require lifelong, risk-tailored surveillance. However, most adult survivors of childhood cancer do not complete recommended surveillance tests such as mammograms or echocardiograms. Objective In partnership with survivors, family physicians, and health system partners, we are designing a provincial support system for high-priority tests informed by principles of implementation science, behavioral science, and design thinking. Methods Our multiphase process was structured as follows. Step 1 consisted of a qualitative study to explore intervention components essential to accessing surveillance tests. Step 2 comprised a workshop with childhood cancer survivors, family physicians, and health system stakeholders that used the Step 1 findings and “personas” (a series of fictional but data-informed characters) to develop and tailor the intervention for different survivor groups. Step 3 consisted of intervention prototype development, and Step 4 involved iterative user testing. Results The qualitative study of 30 survivors and 7 family physicians found a high desire for information on surveillance for late effects. Respondents indicated that the intervention should help patients book appointments when they are due in addition to providing personalized information. Insights from the workshop included the importance of partnering with both family physicians and survivorship clinics and providing emotional support for survivors who may experience distress upon learning of their risk for late effects. In our user-testing process, prototypes went through iterations that incorporated feedback from users regarding acceptability, usability, and functionality. We sought to address the needs of survivors and physicians while balancing the capacity and infrastructure available for a lifelong intervention via our health system partners. Conclusions In partnership with childhood cancer survivors, family physicians, and health system partners, we elucidated the barriers and enablers to accessing guideline-recommended surveillance tests and designed a multifaceted solution that will support survivors and their family physicians. The next step is to evaluate the intervention in a pragmatic randomized controlled trial.
