Clinical News: Patient Data Safety for Dementia Patients Using Apps
As medical advances lead to increases in life expectancy, the number of people who are living with dementia is growing rapidly. According to the 2015 World Alzheimer Report, the number of people with dementia is currently 46.8 million, with an expected rise to 74.7 million in 2030 and 131.5 million in 2050.1 Over the course of illness, dementia patients and their caregivers need education about diagnostic tests, symptom management, and prognostic indicators. In an ideal world, patients and their family members would have ready access to in-person consultations with geriatric specialists. In reality, there is a severe paucity of specialists who can educate families and help plan management of the course of illness.2,3 As a result, cost-effective scalable innovations and resources are needed to address the clinical demands of the rapidly expanding population of patients with dementia.
Mobile Technology: One Possible Solution
Although mobile health apps have generally been associated with younger tech-savvy people, the number of older adults who own smartphones and use them to look up health information is on the rise.4 A recent literature review suggested that mobile health technologies may be used to assess cognitive and mental illness in older adults.5 For this reason, many innovators have concluded that mobile technologies hold great promise for the future of geriatric care, a sentiment that is reflected in the wide array of dementia-focused apps that are available in the Apple App Store.
Patient Privacy: A Potential Pitfall
An Overview of Current Privacy Policies: The Lay of the Land
To answer these questions, we compiled a comprehensive list of health apps for dementia, downloaded as many of the corresponding privacy policies as we could access, and evaluated these policies using a fixed rubric. What we discovered in the process of conducting this analysis was alarming.
Among the 46% of apps with privacy policies, many contained missing information, and the information, where present, pointed to striking gaps in data security. Thirty percent did not explain how user data would be safeguarded, and 24% did not distinguish between how individual and aggregated user data would be handled. For apps that did specify how individual user data would be handled (25 of 72), 80% admitted to the possibility of sharing user data with third parties, 52% admitted to the possibility of selling data in a merger or acquisition, and 36% admitted to the possibility of sharing data with marketers and advertisers.
In summary, despite the potential for health apps to reform dementia care, our review reveals widespread gaps in data security and privacy protections. While these findings would be worrisome in all cases, they are particularly concerning for apps that target dementia patients. After all, these individuals may lack the cognitive capacity to find and interpret convoluted privacy policies, thereby calling into question their ability to consent to giving their health information to an app in the first place. As a result, the trust between app developers and consumers rests upon a tenuous foundation, which, if compromised, could jeopardize the enormous potential that mobile technologies have for enhancing care, improving quality of life, and facilitating aging in place for people with dementia.8,9
In practice, this would require physicians to perform the following steps for apps they are interested in recommending:
• Review the description of or download the app to determine whether it collects personal, diagnostic, or clinical data from its users. If it does not, there should be no risk to privacy and the app should be considered safe for use.
A combination of the answers to these questions, the sensitivity of the data being collected, and the consumer's level of risk tolerance will enable a thoughtful clinician to facilitate informed decision-making on the part of patients and their caregivers. Moreover, by raising patient awareness, physicians may indirectly motivate app developers to bolster safeguards and improve communication about privacy protections, all in an effort to engender consumer trust and thereby maximize their impact on dementia care.
