Inpatient Adherence to Topical Glaucoma Medications before and after an Educational Intervention.

PURPOSE

To assess the inpatient adherence rate and factors associated with adherence to topical glaucoma medications (TGMs) at a single academic institution throughout hospitalization before and after an educational intervention.

DESIGN

Nonrandomized, comparative, retrospective study.

PARTICIPANTS

Inpatients 18 years of age and older admitted to a single academic hospital from January 2014 through June 2019 with a diagnosis of glaucoma who also received TGMs.

METHODS

The medication administration record during admission was examined closely to determine if the TGMs were reconciled and administered correctly before and after an educational intervention with inpatient providers. A simple intervention reached various health care providers through an educational e-mail, communication in a weekly newsletter, and a morning report presentation. Adherence was defined as administration of more than 75% of recommended doses during the inpatient stay. Other collected variables included length of stay and primary diagnosis on admission.

MAIN OUTCOME MEASURES

Adherence rate to inpatient administration of TGMs.

RESULTS

One hundred eighty-four patients (n = 142 before intervention; n = 42 after intervention) were included. The preintervention group had a total of 275 TGMs, of which 207 (75.3%) were administered in accordance with the adherence definition of this study. After the intervention phase, 49 of 56 (87.5%) TGMs were administered with appropriate adherence (P = 0.047). Adherence was associated significantly with a known outpatient medication regimen (P = 0.006) and correct admission reconciliation (P < 0.001).

CONCLUSIONS

When glaucoma patients requiring topical treatment are admitted, approximately one quarter of patients seem to not receive their medications appropriately. In this study, a simple educational intervention was able to improve adherence. To prevent daily fluctuations in intraocular pressure for vulnerable glaucoma patients, inpatient adherence to appropriate medication administration should be stressed continuously. While in the care of health care providers, inpatients should be afforded at least the opportunity to maintain adequate adherence, just as is carried out for other medications related to other chronic medical conditions.
