Impact of socioeconomic position and distance on mental health care utilization by incident users of antidepressants. A Danish nationwide follow-up study

IntroductionEqual access to health care treatment is a highly prioritized goal in most OECD countries. Timely access has become a priority too; in Denmark now with a 4-week deadline from referral to diagnosis. When mental health services become more centralized and allocation of patients to treatment further away from home become more common, it could have a negative impact on the goal of equal access.ObjectiveTo determine the impact of socioeconomic position (SEP) and distance to provider on outpatient mental health care utilization among incident users of antidepressants.MethodA nationwide, Danish, register based, follow-up study on frequencies of contacts to out-patient psychiatric services, psychologist consultations supported by public funding and therapeutic talks by general practice.Preliminary resultsOutpatient-psychiatric services were reached more often by patients in low SEP measured by income, but their frequencies of visits were less. Contacts to psychologists were less than half for patients in low SEP and less frequent too. Mental health service by GP showed low SEP associated with low contact. No difference in use of emergency or inpatient psychiatric services was found. Distance to provider showed interaction with SEP and contact to psychologist and frequencies of contact to outpatient psychiatrists. When distance increased by 5 km, contact to psychologist fell by 11% among lowest income group and frequencies of visits to outpatient psychiatrist fell by 5%.Preliminary conclusionLower SEP is associated with lower mental health care utilization. Increased distance to provider increases inequity in mental health service utilization.Disclosure of interestThe authors have not supplied their declaration of competing interest.
