Views of glaucoma patients on provision of follow-up care; an assessment of patient preferences by conjoint analysis

Aims: To determine patients' preferences for provision of glaucoma follow-up services examining preferences for location, access and personnel for delivery of this care. Methods: 100 patient patients attending the glaucoma outpatient clinic for follow-up review underwent an interview-based assessment during which they completed the visual function questionnaire 25 and ranking of scenario options for provision of follow-up care for their glaucoma. Percentage preferences for aspects of care offered in the conjoint analysis scenario packages and generation of utility values for each of the factor levels included in the scenario design were calculated. Results: Travel time and training of health professional were the most important factors for patients (accounting for over 60%) of their preference. Utility scores were generated for each factor, with shorter travel time and examination by a doctor being the most important features to the patients. Patients who lived furthest from the hospital and had severe visual disability considered the number of visits to complete an episode to be an important feature. Conclusion: Patients ideally would like to travel a short distance and be seen by a doctor when being followed up for their glaucoma.
