Improved Medication Adherence of an Elderly Diabetic Patient at a Dwelling Home Using a Pill Dispenser and Personal Health Records

Fookkun® is a pill dispenser in which single doses of several medications intended to be taken simultaneously are sealed in single film bags rolled onto a medication rotating drum. The system makes musical alert sounds when it is time for the patient to take the medications. If the patient misses a dose, a designated contact, such as the patient's child, is alerted. We conducted an experiment monitoring the use of a pill dispenser (Fookkun®) by an older patient. The participant was a 71-year-old woman with diabetes living in a dwelling home. The experiment lasted approximately 6 months. Fookkun® and the prototype data transmitter were installed at the patient's home. Fookkun®'s medication history data are displayed on the electronic medication record book (E-MRB) and the patient's pharmacist checks the patient's medication history on the E-MRB. The Fookkun® was effective in facilitating medication adherence. The pharmacist and the patient's daughter did not need to check the E-MRB because Fookkun® alerted them when the patient missed her medication. We believe that if the medication history data linked between a pill dispenser and an E-MRB can be shared among medical staff, this will contribute to a medical digital transformation in Japan in the future.

Adherence to a flexible extended regimen for oral hormonal contraception provided in blister packaging compared with an adherence-supporting digital tablet dispenser: historical comparison of data from two clinical studies

BACKGROUND

The Clyk™ digital pill dispenser helps ensure correct and consistent administration of a flexible extended regimen of the combined oral contraceptive, ethinylestradiol (EE) 20 μg/drospirenone 3 mg (EE/drospirenone ; YAZ(®) Flex Flex), guiding users through the intake cycle and 4-day pill break and providing visible and acoustic daily reminders when pill intake is due. A study showed that the audible alarm function of the dispenser could help reduce the number of missed pills, but it lacked an appropriate "non-dispenser" group for a meaningful assessment of the impact of the dispenser on adherence. This study indirectly assessed the overall effect of the digital dispenser on adherence by comparing data from a treatment with standard blister packaging.

MATERIALS AND METHODS

One-year adherence data were compared from two similarly designed, Phase III, open-label, randomized trials of EE/drospirenoneFlex. In study 1, women used diary cards to record adherence with EE/drospirenoneFlex dispensed in blister packs (n=640), and in study 2 the dispenser was used with the alarm activated (n=250) or deactivated (n=248) in addition to using diary cards.

RESULTS

A mean (±SD) of 4.3 (±4.24) missed pills over 1 year were recorded in diary cards among women who dispensed their pills from the blister packages (study 1) compared with 1.0 (±2.4) recorded by the alarm-activated dispenser (study 2). In study 2, a mean of 1.9 (±4.2) missed pills were reported in the diaries over 1 year compared with 4.4 (±9.1) from automatic recording by the dispenser (both arms of study 2), indicating underreporting of missed pills in diary cards vs the digital dispenser. Adjusting for this rate of underreporting, an estimated mean of ten pills were missed over 1 year by women using EE/drospirenoneFlex in blister packs, or ten times more than with the digital dispenser with activated acoustic alarm.

CONCLUSION

The digital dispenser helps reduce the number of missed pills and increases adherence.

Adherence with ethinylestradiol 20 μg/drospirenone 3 mg in a flexible extended regimen supported by the use of a digital tablet dispenser with or without acoustic alarm: an open-label, randomized, multicenter study

OBJECTIVE

To evaluate the effect of a digital dispenser's acoustic alarm function on adherence to ethinylestradiol (EE) 20 μg/drospirenone 3 mg in a flexible extended regimen (EE/drospirenoneFlex) among women in five European countries (France, Germany, Italy, Spain, UK) seeking oral contraception.

STUDY DESIGN

Randomized, parallel-group open-label study.

METHODS

Women aged 18-35 years received EE/drospirenoneFlex administered in a regimen with cycle lengths of their choice with the aid of a digital pill dispenser over 1 year. In group A (N=250), the dispenser's acoustic alarm was activated (ie, acoustic alarm + visual reminder). In group B (N=249), the acoustic alarm was deactivated (ie, visual reminder only). In addition, the women recorded pill intake daily in diary cards. The primary efficacy variable was the mean delay of daily pill release after the dispenser reminded the woman to take a pill (reference time). Secondary efficacy variables included number of missed pills, contraceptive efficacy, bleeding pattern, tolerability, and user satisfaction.

RESULTS

Dispenser data showed a mean (standard deviation [SD]) daily delay in pill release of 88 (126) minutes in group A vs 178 (140) minutes in group B (P<0.0001). Median (lower quartile, Q1; upper quartile, Q3) number of missed pills was 0 (0; 1) in group A vs 4 (1; 9) in group B (P<0.0001). Diary card results revealed similar trends; however, underreporting of missed pills was evident in both groups. No pregnancies were reported during 424 women-years of exposure. Across the two groups, the mean (SD) EE/drospirenoneFlex cycle length was 51.0 (31.8) days with strong regional differences, and the mean (SD) number of bleeding/spotting days was 50.4 (33.0) days. EE/drospirenoneFlex was well tolerated, and 80% of women were satisfied with treatment.

CONCLUSION

The dispenser's activated acoustic alarm improved adherence with daily tablet intake of EE/drospirenoneFlex, reducing missed pills. EE/drospirenoneFlex provided effective contraception and a good tolerability profile.

A randomized controlled trial with a Canadian electronic pill dispenser used to measure and improve medication adherence in patients with schizophrenia

Objective: Medication adherence is extremely important in preventing relapse and lowering symptoms in schizophrenic patients. However, estimates show that nearly half of these patients have poor adherence. The Brief Adherence Rating Scale (BARS) seems to be the most reliable tool assessing adherence in schizophrenia and shows that the antipsychotic adherence ratio (AAR) is about 49.5% in schizophrenia. The aim of the study was to test if an electronic pill dispenser named DoPill^® improved AAR of schizophrenic patients. Furthermore, we compared AAR obtained by the DoPill^® and the BARS, in order to verify whether the DoPill^® provides reliable assessment of medication adherence.

Methods: The DoPill^® is a smart pill dispenser that beeps and flashes at the appropriate time of the day. Each of its 28 compartments is covered by a plastic lamina that, when taken off, sends a signal to the pharmacist. Patients were randomized to the DoPill^® or treatment as usual groups for 6 weeks. The BARS was used as a reference measure.

Results: Forty-six percent of patients were deemed to be non-adherent with antipsychotic medication. The mean AAR was 67% after 6 weeks. DoPill^® recorded better AAR than some of those found in the literature and were lower than the BARS estimate we found.

Conclusion: These results suggest that DoPill^® is a valid tool that provides more reliable and objective data for the clinician about their patient’s adherence, than existing assessment tools like the BARS. Furthermore, the device may help patients successfully manage their medication regimen.
