ABSTRACT
OBJECTIVE:
To evaluate several early outcome measures following diagnosis of psychogenic nonsyncopal collapse (PNSC).METHODS:
Over a 34-month period, a prospective cohort study was conducted of patients referred for tilt-table evaluation of fainting and orthostatic intolerance. Clinical histories were obtained and anxiety and depressive symptom questionnaires were completed prior to testing. Among 539 patients referred, 100 (18.6%) were diagnosed with PNSC. Outcome data were collected by telephone or during routine follow-up a median of 572 days postdiagnosis.RESULTS:
Eighty-four patients (84%) provided outcome data. Following communication of the diagnosis, 32 patients (38%) had immediate PNSC resolution. Attack resolution occurred in 44% by 1 month, 51% by 6 months, 52% by 12 months, 69% after 12 months, and 31% continued to have PNSC at the time of follow-up. Patients with continued PNSC had higher anxiety scores than patients with immediate resolution (p = 0.047). Following diagnosis, emergency department visits for fainting decreased from 78.6% to 20.2% (p = 0.017), and management by psychology or psychiatry increased from 26.2% to 76.2% (p < 0.001). During the follow-up period, 8 patients (9.5%) were hospitalized for suicidal ideation, a median of 253 (range 33-470) days postdiagnosis; 12 patients (14.3%) developed new (non-PNSC) conversion disorders, a median of 86 (range 9-504) days postdiagnosis. Suicidal ideation was associated with higher anxiety (p = 0.007) but not higher depression scores.CONCLUSIONS:
The diagnostic rate of PNSC parallels that of PNES among patients referred for tertiary care evaluations. The improvements in attack frequency following PNSC diagnosis must be tempered by the potential risks of self-harm and the development of new conversion disorders.
