Patients, providers prioritize sociobehavioral factors in glaucoma treatment adherence
Patients and providers agree that sociobehavioral factors are a key determinant of glaucoma treatment adherence, but they disagree in other areas, according to a study published in Optometry and Vision Science.
“Sociobehavioral factors such as poor patient-provider relationship, low self-efficacy and psychological stress have been found to affect adherence in glaucoma,” Shervonne Poleon, BS, of the department of optometry and vision science at the University of Alabama at Birmingham School of Optometry, and colleagues wrote. “We aimed to elicit consensus between patients and providers around key determinants of adherence using Delphi surveys. We used a mixed-methods approach to assess treatment perspectives and hypothesized that patients would place a greater emphasis on sociobehavioral factors compared with providers.”
Researchers evaluated treatment beliefs, barriers, facilitators, motivators and needs in 18 patients with glaucoma and providers. The first round of the survey evaluated agreement with 46 statements on a 5-point Likert scale. In the second round, statements with 80% or more agreement were prioritized by the panelists on degree of importance to treatment.
Among the 46 statements, there was consensus between patients and providers on the influence of perceived treatment efficacy, good provider relationship, good quality of life, psychological stress, glaucoma knowledge, instillation skill and forgetfulness regarding glaucoma adherence, according to the study. The statements that failed to reach consensus dealt with regimen complexity, instillation skill and low motivation.
“To our knowledge, this is the first study to comparatively assess treatment perspectives among patients with glaucoma and providers using both qualitative and quantitative methods. Our hypothesis was partially supported, as both groups prioritized sociobehavioral factors as key treatment beliefs, barriers, motivators, facilitators and needs,” Poleon and colleagues wrote.
“However, per Delphi studies, the external validity of our findings lies in whether they are substantiated in real-world situations,” they added. “Continued juxtaposition of patient and provider perspectives could spotlight other underexplored areas and inform the development of successful interventions for improving treatment adherence in glaucoma.”
