Medication Adherence Apps Miss the Mark on What Patients Really Need

Do Medication Adherence Apps Truly Meet Patient Needs?

Medication Adherence Apps Only Partially Meet User Needs, New Study Finds

A recent study conducted at the University of Basel has revealed a significant gap between the features offered by freely available medication adherence apps and what users actually desire. The research, which combined app testing with user feedback, found that while most apps provide basic tracking capabilities, they often lack the professional feedback and data-sharing features that patients find most valuable.

The study's findings have important implications for clinical research and healthcare professionals seeking to improve medication adherence, which remains a persistent challenge in healthcare with adherence rates for chronic diseases averaging only around 50% according to World Health Organization data. With unintentional nonadherence accounting for approximately half of all cases, often due to forgetfulness or complex treatment regimens, smartphone apps represent a promising intervention tool given that over 96% of the Swiss population owned smartphones as of 2023.

What Methods Revealed the Gaps in App Functionality?

Researchers conducted a comprehensive analysis of medication adherence apps available in the Swiss Apple App Store and Google Play Store, screening 80 apps and ultimately identifying 9 that met their strict eligibility criteria. These apps were systematically tested by scheduling medication intakes for ibuprofen 400 mg twice daily over three consecutive days, with researchers intentionally skipping some doses to evaluate how the apps processed and displayed adherence data.

The study found that tracking history was the most common output feature, present in 89% of the tested apps. Other desirable features were considerably less prevalent: statistics (33%), rewards (22%), exportable files (22%), and charts (11%). "Our results indicate that in the last few years—despite a rapidly growing and evolving field—the outputs of adherence apps remained predominantly unchanged," the researchers noted.

What Do Users Think About These Digital Tools?

To understand user perspectives, the team conducted two focus groups with a total of 8 participants and distributed an online survey completed by 42 respondents with a mean age of 53 years. Notably, 62% of survey participants took regular medication, making them representative of the target population for adherence apps. The survey revealed that tracking history was indeed the most desired feature (mean rating 5.29 on a 7-point scale), followed by exportable files (4.83) and the option to discuss data with healthcare professionals (4.38).

Interestingly, participants showed considerable interest in features that were rarely available in free app versions, particularly those enabling professional interpretation of adherence data. "Users seem to be more interested in the clinical meaning of their adherence behavior and impact on their treatment course rather than getting feedback on their performance with medication use," the researchers observed. Half of the survey participants expressed strong desire for features like the option to discuss data with healthcare professionals and receiving additional recommendations based on their adherence patterns.

The research team identified 13 categories of desired app features, with 6 specifically addressing app outputs and 7 concerning general functions. These were further classified according to their underlying adherence-optimizing strategies: behavioral, educational, or reminder-based. Educational strategies, which aim to increase patients' knowledge about their medication through feedback or professional recommendations, were particularly valued by participants but underrepresented in available apps.

Are These Apps Clinically Validated?

The study also revealed important insights about app characteristics. Of the 9 apps that met inclusion criteria, only 2 (22%) were registered as medical devices according to their store descriptions or websites. Healthcare professional involvement in development was indicated for 4 apps (44%), with 2 mentioning physician involvement and 2 noting pharmacist participation. One app (11%) mentioned involvement from a pharmaceutical company, while the remaining 4 apps (44%) provided no information about their development processes.

What Insights Emerged from Focus Groups and Surveys?

In the focus groups, participants emphasized the importance of professional feedback regarding therapy or intake course. One participant stated: "I would appreciate it if feedbacks were provided. For example, if I experience side effects, I would receive a response like: 'Yes, that's normal and included in 90% of the reported side effects, you don't need to worry.' or 'Please go to the pharmacy.' or 'Please contact your doctor.'" Another participant advocated for additional educational content, noting it would be "helpful to get a reminder or some additional educational material. Something like a simple overview of the 'dos and don'ts' with the most important information about what could influence the therapy, both positively and negatively."

The online survey also revealed important nuances in user preferences. While tracking history was widely desired, rewards were the least popular feature, with a mean score of only 2.81 on the 7-point scale. In fact, 52.4% of participants rated rewards as "not desirable" or "absolutely not desirable" (points 1-2). Additionally, in the free comment section of the survey, 24% of participants suggested additional features, with reminder functions being the most frequently mentioned (10% of participants).

"Adherence apps, either as free or paid version, are not able and neither should be intended to replace HCPs; instead, they could be used to complement current patient care by integrating apps into the treatment setting," the researchers emphasized. This finding suggests a potential new direction for clinical practice, where adherence apps could serve as bridges between patients and healthcare providers rather than standalone solutions.

The study had several strengths, including a heterogeneous participant demographic that better represented the general population, particularly in the online survey. The majority of survey participants were taking regular medication, which aligned well with the target audience for adherence apps. However, there were also limitations, including the focus on freely available apps, which may have underestimated the presence of desirable features in the broader market. Additionally, the exclusion of disease-specific apps and the relatively small sample size limit the generalizability of the findings. None of the survey participants had prior experience with adherence apps, which may have affected their perception of feature utility.

Could These Findings Redefine Clinical Practice?

Could medication adherence apps become more effective tools if they better incorporated professional feedback mechanisms and clinical interpretation of adherence data? This study suggests that bridging the gap between simple reminder functions and meaningful clinical support could significantly enhance the value of these digital tools for both patients and healthcare providers.

What regulatory and practical challenges might arise in implementing more sophisticated adherence app features that connect patients directly with healthcare professionals? As digital health continues to evolve, finding the right balance between patient autonomy and professional oversight remains a critical consideration for developers, clinicians, and health systems alike.

Summary

A comprehensive study from the University of Basel has identified a significant disconnect between the features offered by medication adherence apps and what patients actually need. Researchers analyzed nine freely available apps and gathered feedback from 50 participants through focus groups and surveys. While most apps provide basic tracking capabilities—with 89% offering medication history logs—they critically lack features that users value most: professional feedback, data-sharing with healthcare providers, and clinical interpretation of adherence patterns. The study found that only 22% of apps were registered as medical devices, and just 44% involved healthcare professionals in their development. Survey participants, 62% of whom took regular medication, strongly desired educational features and the ability to discuss their adherence data with clinicians, rating these features at 4.38 and 4.83 on a seven-point scale respectively. However, such features were rarely available in free app versions. Users expressed particular interest in understanding the clinical meaning of their adherence behavior rather than simply receiving performance-based rewards, which were the least popular feature. The research highlights that effective medication adherence apps should not replace healthcare professionals but rather serve as complementary tools that bridge the gap between patients and providers. This finding has important implications for improving medication adherence, which remains problematic with only 50% adherence rates for chronic diseases according to WHO data, and approximately half of nonadherence cases being unintentional due to forgetfulness or complex regimens.
