Child-resistant containers for the elderly?

With the introduction of child-resistant medication containers, the geriatric patient has suffered another setback in an already poor record of medication compliance. Most physicians, while applauding the remarkable decrease in child poisonings resulting from safety closure devices, are not aware of the burden that child-resistant medication containers has imposed on the elderly. Nor are they aware of methods to correct the problem. Elderly patients, however, are keenly aware of the problems of child-resistant medication containers but are ignorant about methods to overcome the difficulty in opening and closing them.


Electronic medication packaging devices and medication adherence: A systematic review

Importance  Medication nonadherence, which has been estimated to affect 28% to 31% of US patients with hypertension, hyperlipidemia, and diabetes, may be improved by electronic medication packaging (EMP) devices (adherence-monitoring devices incorporated into the packaging of a prescription medication).

Objectives  To investigate whether EMP devices are associated with improved adherence and to identify and describe common features of EMP devices.

Evidence Review  Systematic review of peer-reviewed studies testing the effectiveness of EMP systems in the MEDLINE, EMBASE, PsycINFO, CINAHL, International Pharmaceutical Abstracts, and Sociological Abstracts databases from searches conducted to June 13, 2014, with extraction of associations between the interventions and adherence, as well as other key findings. Each study was assessed for bias using the Cochrane Handbook for Systematic Reviews of Interventions; features of EMP devices and interventions were qualitatively assessed.

Findings  Thirty-seven studies (32 randomized and 5 nonrandomized) including 4326 patients met inclusion criteria (10 patient interface–only “simple” interventions and 29 “complex” interventions integrated into the health care system [2 qualified for both categories]). Overall, the effect estimates for differences in mean adherence ranged from a decrease of 2.9% to an increase of 34.0%, and the those for differences in the proportion of patients defined as adherent ranged from a decrease of 8.0% to an increase of 49.5%. We identified 5 common EMP characteristics: recorded dosing events and stored records of adherence, audiovisual reminders to cue dosing, digital displays, real-time monitoring, and feedback on adherence performance.

Conclusions and Relevance  Many varieties of EMP devices exist. However, data supporting their use are limited, with variability in the quality of studies testing EMP devices. Devices integrated into the care delivery system and designed to record dosing events are most frequently associated with improved adherence, compared with other devices. Higher-quality evidence is needed to determine the effect, if any, of these low-cost interventions on medication nonadherence and to identify their most useful components.
