Introduction In recent years, psychiatry in the United Kingdom
has faced an important challenge due to the shortage of beds for
patients with increased lengths of stay. Available resources have
been saturated due to the reduced capability of psychiatric hos-
pitals to provide spaces for patients needing access to psychiatric
care.
Objectives This research provides a figure of length of stay linked
to psychiatric pathology at discharge.
Aim To establish the length of admission of psychiatric patients.
Methods The sample comprised 137 discharges from a general
adult psychiatric ward distributed over the first 8months of 2016.
Results were analyzed by descriptive statistics and meta-analysis.
Results Overall, longer periods of admission were recorded for
psychoses and shorter periods for adjustment disorders. Psychoses
had a median length of admission of 28 days (range = 3–374);
borderline personality disorders, 10 days (range = 1–249);
mood disorders, 14 days (range = 2–74); drug addictions, 6 days
(range = 1–222); and adjustment disorders, 5 days (range = 1–55).
Meta-analysis provided a confidence interval estimate
for the whole model of 24.314 days (95% CI = 13.00–35.621)
with P < .001. Meta-analysis results also provided t2 = 101.061,
Cochrane’s Q (df = 4) = 14.327, I2 = 72.081, with P = .006.
Conclusions Psychoses are conditions that require longer admis-
sions, whereas adjustment disorders are more transient patholo-
gies. Borderline personality disorder is somewhat of a hybrid
condition. Overall, patients remain in hospital for about a month
(24 days).

Introduction Evidence shows that the prevalence and severity of
mental disorders and the need for psychiatric admission is influ-
enced by socio-demographic and contextual factors.
Objectives To characterize the severity of hospital admissions for
psychiatric care due to common mental disorders and psychosis in
Portugal.
Aims This retrospective study analyses all acute psychiatric
admissions for common mental disorders and psychosis in four
Portuguese departments of psychiatry in the metropolitan areas of
Lisbon and Porto, and investigates the association of their severity
with socio-demographic and clinical factors.
Methods Socio-demographic and clinical variables were
obtained from the clinical charts of psychiatric admissions in
2002, 2007 and 2012 ( n = 2621). The number of hospital admis-
sions per year (>1) and the length of hospital stay (31 days)
were defined as measures of hospital admission severity. Logistic
regression analysis was used to assess which socio-demographic
and clinical factors were associated with both hospital admission
severity outcomes.
Results Results showed different predictors for each outcome.
Being widowed, low level of education, being retired, having
psychiatric co-morbidity, and a compulsory admission were sta-
tistically associated (P < 0.05) with a higher number of hospital
admissions. Being single or widowed, being retired, a diagnosis
of psychosis, and a compulsory admission were associated with
higher length of hospital stay, while having suicidal ideation was
associated with a lower length of hospital stay.
Conclusions Socio-demographic and clinical characteristics of
the patients are determinants of hospital admissions for psychiatric
care and of their severity.
