Elders' nonadherence: its assessment and medication reminding by voice mail

This study investigates four questions related to the problem of medication nonadherence among elders. First, does memory failure play a significant role in nonadherence? Second, can memory-related nonadherence be predicted by simple tests of cognitive performance? Third, can the new portable bar code scanner technology be used to unobtrusively monitor nonadherence? Most importantly, can inexpensive telephone voice mail technology be used to improve medication adherence? The results show that: elders have substantial levels of forgetting; nonadherence decreases with higher cognitive test scores; portable bar code scanners are useful for monitoring adherence; and voice mail reduces tardiness and complete forgetting.
