Factors related to admission of psychiatric patients to medical wards from the general hospital emergency department: a 3-year study of urgent psychiatric consultations.

OBJECTIVE: Emergency Rooms (ER) of Emergency Departments (ED) in General Hospitals (GH) have a role in providing for psychiatric evaluation. The aims of the present study were to examine the decision-making process of consultation psychiatry at the GH-ER and to analyze the differences between psychiatric patients admitted to a medical ward with those admitted to the psychiatry unit and those who are discharged from the ER. METHOD: Over a period of 3 years, psychiatric consultations requested by ER of ED physicians to the GH Psychiatric service were recorded by using a form to describe epidemiological and clinical data on the consultation process. RESULTS: Of 1,962 psychiatric consultations, most regarded subjects who had had previous psychiatric contacts (76.2%) and at least one psychiatric admission (53.6%), and were currently cared for by the Mental Health Services (51.1%). Neurotic/stress-related syndromes (27.98%), schizophrenia (27.67%), and personality disorders (21.81%) were the most frequent ICD-10 diagnoses. The psychiatrist's disposal was to discharge the patient in 49.9% cases, to admit him/her to medical wards of the GH (MGH; 26.9%) or to the acute inpatient psychiatric ward (AIP; 23.1%). MGH group statistically differed from AIP group for being female (p < 0.01), older (p < 0.01), more likely having an ICD-10 diagnosis of neurosis/stress-related syndromes (p < 0.01) or organic mental disorder (p < 0.01), and less likely having a diagnosis of schizophrenia (p < 0.01), being in charge of the Mental Health Services (p < 0.01), and having had previous psychiatric admissions (p < 0.01). These results were confirmed by logistic regression analysis. CONCLUSIONS: The study shows that the medical wards of the General Hospital are a significant entry-point for providing psychiatric care of patients with ICD-10 neurotic and stress-related syndromes, even if without specific medical problems.

Violence in psychiatric units: a 7-year Italian study of persistently assaultive patients.

BACKGROUND: The problem of violence and aggressive behaviour among patients with psychiatric disorders need careful assessment to improve the quality of psychiatric care. The aim of this paper is to describe the characteristics of repeated episodes of violence among patients admitted to an Italian psychiatric ward. METHODS: All violent behaviours, which occurred in a 15-bed psychiatric inpatient unit over a 7-year period, were assessed by using the Staff Observation Aggression scale (SOAS). RESULTS: Of a total of 3.507 admissions, 409 aggressive episodes were recorded by 160 patients (rate per admission 11.6%). A total of 65 patients exhibited two or more episodes and 95 patients showed a single episode. Repeatedly violent patients had a higher length of stay in the unit, a higher number of previous admissions and a higher number of previous violent episodes. No difference was found in terms of psychiatric diagnosis, socio-demographic variables, type of admission (voluntary versus involuntary), ward overcrowding and characteristics of violent episodes (means, aims and consequence). CONCLUSIONS: In spite of the low prevalence of violent incidents among Italian psychiatric inpatients, careful monitoring of clinical variables associated with repeated violent episodes may help physicians recognise and prevent violence episodes among acute psychiatric inpatients.

The Lindblom roller.

Neuropathic pain is caused by injury of the peripheral or central nervous system. The neurological examination of the sensory system in neuropathic pain patients guides the anatomical localization of the injury. Among the sensory modalities to be tested, priority should be given to those subserved by small peripheral sensory fibers or by the spinothalamic tract that most commonly are abnormal in neuropathic pain patients. Testing of cold and warm perception was traditionally carried out in the clinic using tubes filled with water at different temperatures, a cumbersome method that has limited the routine examination of these sensory modalities. The Lindblom roller offers a practical and effective method of readily testing temperature perception and is among the best available clinical tools for delineating the anatomical boundaries of a sensory abnormality. Routinely use of the Lindblom roller shall be standard bedside clinical assessment of neuropathic pain patients. To exemplify this statement we describe two patients affected by complex and fluctuating painful sensory abnormalities caused by an extradural mass compressing the spinal cord. The level of the injury was readily localized with a roller kept at room temperature.

Lidocaine test in neuralgia.

Ten patients with organic nerve injury causing chronic neuropathic pain were tested for the effects of intravenous lidocaine versus saline upon psychophysical somatosensory variables. The variables assessed were the subjective magnitude of pain, area of mechanical hyperalgesia and presence and magnitude of thermal heat/cold hyperalgesia. The study methods applied to evaluate these conditions were the conventional testing of somatosensory submodalities with area mapping and the subjective magnitude estimation of spontaneous pain. It was found that spontaneous pain and mechanical hyperalgesia were consistently improved, transiently, by intravenous administration of lidocaine in all 10 patients; areas of hyperalgesia which extended beyond the territory of the nerve also improved transiently. Spontaneous pain and mechanical hyperalgesia, but not hypoesthesia, were transiently improved by injection of saline in only 1 of the 10 patients. This outcome is probably due to a placebo effect. This improvement is in keeping with the inhibition of anomalous neural impulses which can be generated anywhere along the sensory channels responsible for generating spontaneous pain and hyperalgesia. Thus, intravenous lidocaine is proposed as a diagnostic aid in the examination of patients complaining of complex sensory disorders associated with nerve injury. The transient pain relief may allow a fuller identification of the area of sensory loss.
