PURPOSE: To determine the prevalence of psychiatric disorders during hospitalization for hematopoietic stem-cell transplantation (SCT) and to estimate their impact on hospital length of stay (LOS). PATIENTS AND METHODS: In a prospective inpatient study conducted from July 1994 to August 1997, 220 patients aged 16 to 65 years received SCT for hematologic cancer at a single institution. Patients received a psychiatric assessment at hospital admission and weekly during hospitalization until discharge or death, yielding a total of 1,062 psychiatric interviews performed. Psychiatric disorders were determined on the basis of the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition. Univariate and multivariate linear regression analyses were used to identify variables associated with LOS. RESULTS: Overall psychiatric disorder prevalence was 44.1%; an adjustment disorder was diagnosed in 22.7% of patients, a mood disorder in 14.1%, an anxiety disorder in 8.2%, and delirium in 7.3%. After adjusting for admission and in-hospital risk factors, diagnosis of any mood, anxiety, or adjustment disorder (P =.022), chronic myelogenous leukemia (P =.003), Karnofsky performance score less than 90 at hospital admission (P =.025), and higher regimen-related toxicity (P <.001) were associated with a longer LOS. Acute lymphoblastic leukemia (P =.009), non-Hodgkin's lymphoma (P =.04), use of peripheral-blood stem cells (P <.001), second year of study (P <.001), and third year of study (P <.001) were associated with a shorter LOS. CONCLUSION: Our data indicate high psychiatric morbidity and an association with longer LOS, underscoring the need for early recognition and effective treatment.
STUDY OBJECTIVES: Narcolepsy is a neurological disorder whose clinical features include excessive daytime sleepiness, hypnagogic hallucinations, cataplexy, sleep paralysis, and disrupted nocturnal sleep. It has been shown that there may be quite a long interval between the onset of symptoms, and the correct diagnosis. We tested the hypothesis that given their severe symptomatology, these patients would have been diagnosed more often with a variety of psychiatric and neurologic conditions than controls in the year prior to confirmation of their narcolepsy diagnosis. DESIGN: Using the Province of Manitoba Health database, we compared the diagnoses made in the year prior to initial sleep disorder center evaluation of 77 patients with narcolepsy (33 males, 44 females) and 1,155 matched control subjects from the general population. SETTING: Sleep disorders center in University-based teaching hospital PARTICIPANTS: N/A. INTERVENTIONS: N/A. MEASUREMENTS AND RESULTS: Patients were much more likely than controls to be diagnosed with mental disorders (Odds ratio (OR) = 4.0645; 95% confidence limit (CL) = 2.4671-6.6962; p<0.0001) and nervous system disorders (OR= 5.0495; CL = 3.0606 -8.3309; p<0.0001) and there was a trend towards more injuries in these patients (OR =1.6316; CL = 0.9857-2.7007; p=0.0514). We found that cases were statistically much more likely than controls to have received a diagnosis for neurotic disorders (17% of cases), depression (16%), personality disorders (3%) and adjustment reaction (4%). Although the cases had twice as many doctor visits as the controls (9.3 +/- 0.97 (sem) vs. 4.8 +/- 0.17 p<0.0001), only 38% of them had received a diagnosis of narcolepsy in the year prior to sleep specialist evaluation. Neurologists had the highest "success rate" for correct diagnosis: neurologists diagnosed narcolepsy in 55% of the cases they had seen. The other medical practitioners diagnosed narcolepsy in a much smaller percentage of the cases they had seen: 23.5% for internists (excluding neurologists), 21.9% for general practitioners, 11.1% for psychiatrists, and 0% for pediatricians. CONCLUSIONS: In the year prior to documentation of narcolepsy in a sleep disorders center, patients with narcolepsy were diagnosed with a wide variety of mental and neurologic disorders. Our findings are supportive of either the coexistence of these disorders in narcolepsy patients or a high frequency of missed diagnosis by their clinicians. The latter may help explain the very long interval between onset of symptoms and correct diagnosis.
BACKGROUND: Many people who develop schizophrenia have impairments in intellectual and social functioning that are detectable from early childhood. However, some patients do not exhibit such deficits, and this suggests that they may have suffered less neurodevelopmental damage. We hypothesized that the aetiology and form of schizophrenia may differ in such patients. We therefore studied a group of schizophrenic patients who were functioning well enough to enter university prior to illness onset. METHODS: The casenotes of 46 university-educated patients and 48 non-university-educated patients were rated on several schedules including the OPCRIT checklist, and the two groups were compared using univariate statistical techniques. Principal components analysis was then performed using data from all patients, and the factor scores for each principal component were compared between groups. RESULTS: Univariate analyses showed the university-educated patients had an excess of depressive symptoms, and a paucity of core schizophrenic symptoms. Four principal components emerged in the principal components analysis: mania, biological depression, schizophrenic symptoms, and a reactive depression. University-educated patients scored significantly higher on the reactive depression principal component, and lower on the schizophrenic symptoms principal component, than the non-university-educated patients.
