Interval between symptom onset and hospitalization in mania
Abstract:
Previous studies of illness onset in mania lack a frequency distribution for the interval between symptom onset and hospitalization (hospital latency), although a bimodal distribution of illness onset been suggested. We identified 100 patients hospitalized for mania and found a unimodal distribution, with mean +/- SD of 3.3 +/- 3.2 weeks for hospital latency. Cases with short hospital latency (< 1 week, n = 15) were younger and had briefer psychiatric histories. The data were compared to other studies of hospital latency in mania.
Insights
This study found a unimodal distribution for hospital latency in mania, averaging 3.3 weeks. Younger patients with shorter psychiatric histories experienced shorter intervals between mania symptom onset and hospitalization.
Area of Science:
- Psychiatry
- Bipolar Disorder Research
Background:
- Previous research on mania onset lacked detailed frequency distributions for hospital latency.
- A bimodal distribution for illness onset in mania has been suggested but not confirmed.
Purpose of the Study:
- To determine the frequency distribution of hospital latency in patients hospitalized for mania.
- To identify characteristics associated with short hospital latency.
Main Methods:
- Analysis of hospital latency in 100 patients admitted for mania.
- Comparison of patient demographics and psychiatric history between short and long latency groups.
Main Results:
- A unimodal distribution was observed for hospital latency.
- The mean hospital latency was 3.3 weeks (± 3.2 weeks).
- Patients with short latency (< 1 week) were younger and had briefer psychiatric histories.
Conclusions:
- The study provides a frequency distribution for hospital latency in mania, refuting previous suggestions of bimodality.
- Younger age and shorter psychiatric history are associated with rapid hospitalization following mania symptom onset.
