Prompted Text-Based Vital Sign Recording Versus Unprompted Electronic Medical Record Entries in Patients With Advanced Heart Failure: Observational Study.
Wu J, Chen J, et al. • JMIR formative research • 2026
Although MPOTA was associated with substantially higher patient engagement levels compared to unprompted patient reporting, neither demonstrated significant differences in hospitalizations or emergency room visits across engagement levels or between programs.
Key Findings
Results
The text-based prompting system (MPOTA) achieved dramatically higher patient engagement rates than unprompted electronic medical record flowsheets (PEF).
MPOTA group showed a median engagement rate of 66.67% (IQR 30.67%-88.24%)
PEF group had a median engagement rate of 2.29% (IQR 0%-23.93%)
890 total patients were included: 301 in the MPOTA group and 589 in the PEF group
Both groups reported daily weight, blood pressure, and pulse
Results
Mean hospitalizations declined after program initiation in both groups, but the reduction was statistically significant only in the PEF group.
MPOTA group: mean hospitalizations declined 21% (from mean 0.53, SD 0.90 to mean 0.42, SD 0.88; P=.06)
PEF group: mean hospitalizations declined 18% (from mean 0.50, SD 0.86 to mean 0.41, SD 0.80; P=.03)
The reduction was described as 'small' in both groups
All analyses of clinical outcomes were exploratory and underpowered
Results
Mean emergency room visits did not significantly change in either the MPOTA or PEF group after program initiation.
No significant changes in emergency room visits were observed in either group
Regression analyses showed no significant association between engagement level and emergency room utilization
Analyses were exploratory and underpowered to detect clinically meaningful effects
Results
Regression analyses found no significant association between engagement level and hospitalization or emergency room utilization.
Engagement was categorized as none, low, medium, and high
There were no significant differences in hospitalization or emergency room visit rates across engagement categories
Medium engagement was associated with a nonsignificant trend toward fewer events
No significant differences were found between programs in clinical outcomes
Methods
The study was conducted among patients in the University of Michigan Advanced Heart Failure Program using two distinct remote monitoring modalities.
MPOTA (MiChart Patient Outreach Texting Application) used 2-way text-based communication to prompt patients
PEF (patient enrolled flowsheets) relied on unprompted patient reporting through electronic medical records
The primary metric was the consistency of patient-reported vital signs
Secondary descriptive metrics included variations in hospitalization and emergency room visits pre-enrollment and postenrollment
What This Means
This research suggests that sending patients text message prompts to record their vital signs (weight, blood pressure, and pulse) dramatically increases how often they actually do so compared to leaving it up to patients to voluntarily enter data into an online health portal. Among nearly 900 patients with advanced heart failure, those receiving text prompts reported their vitals about 67% of the time on average, while those using the self-directed online portal did so only about 2% of the time. Despite this large difference in participation, the two approaches did not produce meaningfully different rates of hospital visits or emergency room use.
Both groups showed small reductions in hospitalizations after joining their respective monitoring programs, but these reductions were modest and only reached statistical significance in the self-directed portal group. The text-messaging group showed a 21% decline in hospitalizations that did not reach statistical significance, possibly because the study did not have enough participants to reliably detect such an effect. Emergency room visits did not change significantly in either group, and the level of engagement (how often patients reported their vitals) was not linked to better or worse hospital outcomes in either program.
This research suggests that mobile text-based communication is a promising tool for keeping heart failure patients engaged in remote monitoring, solving a longstanding problem of low participation. However, whether that improved engagement actually leads to better health outcomes — fewer hospitalizations or emergency visits — remains unclear and requires larger, more rigorous studies to determine. The findings highlight that getting patients to participate is only one piece of the puzzle; future research needs to examine whether consistent monitoring translates into meaningful clinical benefits.
