Temporal trends in inpatient care use for adult mental disorders in Czechia: a nationwide register-based study from 1994 to 2015

Purpose To describe temporal trends in inpatient care use for adult mental disorders in Czechia from 1994 until 2015. Methods Data from the nationwide register of inpatient care use and yearly census data were used to calculate (a) yearly admissions rates, (b) median length of stay, and (c) standardized inpatient-years for adult mental disorders (ICD-10 codes F0-F6] or G30). Segmented regressions were used to analyze age- and sex-specific temporal trends. Results Admission rates were increasing in adults (average annual percent change = 0.51; 95% confidence interval = 0.16 to 0.86 for females and 1.01; 0.63 to 1.40 for males) and adolescents and emerging adults (3.27; 2.57 to 3.97 for females and 2.98; 2.08 to 3.88 for males), whereas in seniors, the trend was stable (1.22; -0.31 to 2.73 for females and 1.35; -0.30 to 2.98 for males). The median length of stay for studied mental disorders decreased across all age and sex strata except for a stable trend in male adolescents and emerging adults (-0.96; -2.02 to 0.10). Standardized inpatient-years were decreasing in adults of both sexes (-0.85; -1.42 to -0.28 for females and -0.87; -1.19 to -0.56 for males), increasing in female adolescents and emerging adults (0.95; 0.42 to 1.47), and stable in the remaining strata. Conclusion Psychiatric hospital admissions were increasing or stable coupled with considerable reductions in median length of stay, suggesting that inpatient episodes for adult mental disorders have become more frequent and shorter over time. The overall psychiatric inpatient care use was decreasing or stable in adults and seniors, potentially implying a gradual shift away from hospital-based care.
