The effect of menstruation on psychiatric hospitalization.

This study evaluated the effect of menstruation on psychiatric hospitalization. We conducted a retrospective chart review of the medical records of 177 women who met the eligibility criteria. Data collected included demographic details, primary and secondary diagnoses, date of last menstrual period (LMP), medication adherence, psychiatric hospitalization length of stay, previous psychiatric admissions (including those related to menstruation), discharge referrals, and readmissions. The majority of women were admitted for major depression, were single, Caucasian, and had a mean age of 34. A disproportionate percentage (37%) of women had their LMP within 5 days of psychiatric hospitalization (p = 0.0006). The overall average length of stay was 4.37 days, and 48.3% had a previous psychiatric admission. Medication adherence was routinely not documented (77.4%). Psychiatric hospitalizations for women are significantly greater within 5 days of their LMP. Nursing education and improved documentation are warranted to decrease the potential for readmission.
