A register-based observational cohort study on persistent frequent users of emergency services in a Finnish emergency clinic.

BACKGROUND

The focus of emergency room (ER) treatment is on acute medical crises, but frequent users of ER services often present with various needs. The objectives of this study were to obtain information on persistent frequent ER service users and to determine reasons for their ER service use. We also sought to determine whether psychiatric diagnoses or ongoing use of psychiatric or substance use disorder treatment services were associated with persistent frequent ER visits.

METHODS

A cohort (n = 138) of persistent frequent ER service users with a total of 2585 ER visits during a two-year-period was identified. A content analysis was performed for 10% of these visits. Register data including International Classification of Primary Care 2 (ICPC-2) -codes and diagnoses were analyzed and multivariable models were created in order to determine whether psychiatric diagnoses and psychosocial reasons for ER service use were associated with the number of ER visits after adjusting for covariates.

RESULTS

Patients who were younger, had a psychiatric diagnosis and engaged in ongoing psychiatric and other health services, had more ER visits than those who were not. Having a psychiatric diagnosis was associated with the frequency of ER visits in the multivariable models after adjusting for age, gender and ongoing use of psychiatric or substance use disorder treatment services. Reasons for ER-service use according to ICPC-2 -codes were inadequately documented.

CONCLUSIONS

Patients with psychiatric diagnoses are overrepresented in this cohort of persistent frequent ER service users. More efficient treatments paths are needed for patients to have their medical needs met through regular appointments.
