Medical Clearance Components History and physical exam Mental status examination Testing Treatment
Protocol for the Emergency Medicine Evaluation of Psychiatric Patients Team of Illinois psychiatrists and emergency physicians met to develop a consensus document in 1995 Coordinate transfers to a State Operated Psychiatric Facility (SOF) Services provided at an SOF: Monitor vital signs, routine neurological monitoring, glucose finger sticks, fluid input and output, insertion and maintenance of urinary catheters, oxygen administration and suction, clinical laboratories, radiographic procedures, intramuscular and subcutaneous injections. Level III Zun, LS, Leiken, JB, Scotland, NL et. al: A tool for the emergency medicine evaluation of psychiatric patients (letter), Am J Emerg Med, 14:329-333, 1996.
Consensus Document Tool establishes the EP as the decision maker if lab tests are clinically indicated Observation is the means to determine if the presentation is from drugs/alcohol May be used for adults and children Medical findings may or may not preclude transfer to a SOF Checklist developed as a transfer document

What laboratories and radiographs does the patient need?
Evidence to Test 46% of psychiatric patients had unrecognized medical illness. Hall, RC, Gardner, ER, Popkin, MK, et. al: Unrecognized physical illness prompting psychiatric admission: A prospective study. Am J Psych 1981; 138: 629-633. 92% of one or more previously undiagnosed physical diseases. Bunce, DF: Jones, R, Badger, LW, Jones, SE: Medical Illness in psychiatric patients: Barriers to diagnoses and treatment. South Med J 1982: 75:941-944. 43% of psychiatric clinic patients had one or several physical illnesses. Koranyi, E: Morbidly and rate of undiagnosed physical illness in a psychiatric population. Arch Gen Psych 1979; 36: 414-419.
Evidence to Test In a recent retrospective review of 158 patients, 6% of the psych patients had undiagnosed physical illness that might contribute to psychiatric illness. Skelcy, K, Wagner, MJ: Medical clearance of the psychiatric patient, ACEP Research Forum, 2000. Osborn recommends a moderately comprehensive battery of tests that will detect 90% of all medical illnesses. Osborn, H: Medical clearance of the patient with psychiatric symptoms. 357-371.
Psych History vs New Onset 100 consecutive patients aged 16-65 with new psychiatric symptoms. 63 of 100 had organic etiology for their symptoms History (100) 53% ABN 27% sign PE (100)64% ABN 6% sign CBC (98)72% ABN 5% sign SMA-7 (100)73% ABN 10% sign Drug screen (97)37% ABN 29% sign CT scan (82)28% ABN 10% sign LP (38)55% ABN 8% sign Patients need extensive laboratory and radiographic evaluations including CT and LP. Level II Hennenman, PL, Mendoza, R, Lewis, RJ: Prospective evaluation of emergency department medical clearance. Ann Emerg Med 1994;24:672-677.
Evidence Not to Test Most laboratories, EKG and radiographic testing should be abandoned in favor of a more clinically driven and cost effective process. Allen, MH, Currier, GW: Medical assessment in the psychiatric emergency service. New Directions in Mental Health Services 1999;82:21-28. Patients with primary psychiatric complaints with other negative findings do not need ancillary testing in the ED. Korn,CS, Currier, GW, Henderson, SO: “Medical Clearance” of psychiatric patients without medical complaints in the emergency department. J Emerg Med 2000;18:173-176.
Evidence Not to Test Medical and substance abuse problems could be identified by initial vital signs together with a basic history and physical examination. Olshaker, JS, Browne, B, Jerrard, DA, Prendergast, H, Stair, TO: Medical clearance and screening of psychiatric patients in the emergency department. Acad Emerg Med 1997;4:124-128. Universal laboratory and toxicologic screening is of low yield. Olshaker, JS, Browne, B, Jerrard, DA, Prendergast, H, Stair, TO: Medical clearance and screening of psychiatric patients in the emergency department. Acad Emerg Med 1997;4:124-128.
EMTALA Requirements EMTALA does not require the patient to havelaboratories or radiographies performed to ensure medical stability. It does require that psychiatric patients with medical problems are transferred to a psychiatric facility that is equipped to handle the patients’ medical problem. Moy, MM: EMTALA and Psychiatry in The EMTALA Answer Book 2nd Edition. Gaithersburg, MD:Aspen; 2000
What information needs to be transmitted?
What needs to be documented? Poor documentation of medical examination of psychiatric patients 298 charts reviewed in 1991 at one hospital Triage deficiencies Mental status56% Physician deficiencies Cranial nerves45% Motor function38% Extremities27% Mental status20% “medically clear” documented in 80% Level II Tintinalli, JE, Peacodk, FW, Wright, MA: Emergency medical evaluation of psychiatric patients. Ann Emerg Med 1994; 23:859-862.
The Term “Medically Clear” Tintinalli states it should be replaced by discharge note History and physical examination Mental status and neurologic exam Laboratory results Discharge instructions Follow up plans The term has greater capacity to mislead than to inform correctly Concern about misdiagnosis, premature referral and misunderstandings Recommends education and process factors –Weissberg, M: Emergency room clearance:An educational problem. Am J Psych 1979;136:787-789. “Medically stable” vs. “medically clear”
What treatment does the patient need in the ED?
Treatment Physical restraints Chemical restraints Combination
Physical Restraints HCFA presents standards for ordering, assessing, monitoring, reevaluating and terminating restraints.

Accessed on June 29, 2000. http://www.jcaho.org/edu_pub/sealer/sea8.html JCAHO based their comments on the Hartford Courant that found 142 deaths from restraints in psychiatric hospitals from 1988-1999 Weiss, EM, Remez, M: National restraint death database in The Hartford Courant. Available at http:www.courant.com/news/special/restraint/data.stm. Accessed on March 25, 1999.
Complications of Patient Restraints The purpose of the study was to determine the type and rate of complications of patients restrained in the ED. A prospective study for one year of all patients who were restrained in a community, inner city teaching hospital emergency department. The ED nurses or physicians completed a restraint study checklist. Level II Leslie S Zun, MD, MBA, FAAEM Accepted for publication
Results - Characteristics 221 patients were restrained in the ED and enrolled in the study from November, 1999 to September, 2000. The mean age was 36.35 years (range 14-89). 71.7% were male. 70.9% were African Americans,15.8% Hispanic and 12.2% Caucasian.
Results - Complications Complication rate 5.4% 12 complications: Getting out of restraints (6) Injured others (2) Vomiting (1) Injured self (1) Other (1) Hostile or increased agitation (1) Aspiration (0) Spitting (0) Death (0) No major complications such as death or disability
Chemical Restraints What are chemical restraints? How is it different than treatment? What are the indications for chemical restraints? What is the appropriate treatment for ED patient agitation?
Use of Chemical Restraints Diagnosis General Medical Etiology Substance Intoxication Psychiatric Disturbance Dosage Single dose or multiple doses Route and onset Oral IM IV
Treatment Guidelines General Medical Etiology High Potency Conventional antipsychotics Benzodiazepine Combination Substance Intoxication Benzodiazepine Psychiatric Disturbance High potency conventional antipsychotics Benzodiazepine Combination Level III Allen, MH, Currier. GW, Hughes, DH, Reyes, Harde, M, Docherty, JP: Treatment of behavioral emergencies. Post grad Med 2001; S1-88.
Consumer preference Prospective study of the refusal of treatment with antipsychotic agents Sample of 1434 psychiatric patients at 4 acute inpatient units 103 of 1434 refused (9.3%) oral meds Older, higher social class and fewer with antiparkinson meds Most patients will assent to oral medication (>90%) Level II Hoge, ST, Appelbaum, PS, Lawlor, T, et. Al: A prospective, multicenter study of patients’ refusal of antipsychotic medication. Arch Gen Psych 1990: 47:949-956.
Use of Chemical Restraints Offset Sedation Safety Hypotension Dystonic reaction Neuroleptic malignant syndrome Akathisia Respiratory depression Increased violent behavior Small study demonstrated marked increase in violent behavior with high potency (Haloperidol) vs low potency neuroleptics (Chlorpromazine). Herrera, JN, Sramek, JJ, Costa, JF et al: High potency neuroleptics and violence in schizophrenics. J Nervous Mental Dis 1988; 176:558-561. Tolerability
Choice of Medications Use of antipsychotics Haloperidol Chlorpromazine Droperidol Loxapine Thiothixene Molidone Use of atypical antipsychotic Clozapine Risperidone Olanzapine Ziprasidone
Choice of Medications Use of benzodiazepines Lorazepam Flunitrazepam Use of combinations Haloperidol and Lorazepam Risperidone and Lorazepam
Problems with Current Medications Sedation Dystonic reactions Hypotension Problems with Droperidol WARNING : Cases of QT prolongation and/or torsades de pointes have been reported in patients receiving INAPSINE at doses at or below recommended doses. Some cases have occurred in patients with no known risk factors for QT prolongation and some cases have been fatal.
Choice of Medications New medications Ziprasidone (Geodon) Oral or IM Unrelated to phenothiazine or butyrophenone IM is indicated for the treatment of acute agitation in schizophrenic patients Low incidence of dystonia and hypotension Concern about QT prolongation Risperidone (Risperdal) Oral New chemical class Indicated for treatment of schizophrenia Infrequent dystonia and hypotension
Advantages of the New Medications Little hypotension Less sedation Few dystonic reactions Replacement for Droperidol?
Meta-analysis of drug studies Reviewed 22 studies; only 2 performed in an ED Reviewed use of all meds including haloperidol, lorazepam, loxapine, chlorpromazine, molindone, phenobarbital, amobarbital, droperidol, flunitrazepam and combination. “It would appear that lorazepam alone is superior to haloperidol for agitation” “Combinations studies did not use comparable doses but did demonstrate that the combination is better in the first few hours” Level III Allen, MH: Managing the agitated psychotic patient: A reappraisal of the evidence. J Clin Psychiatry 2000;61(suppl 14):11-20.
Meta-analysis of drug studies Onset and route Haloperidol IV is fast, IM is 30-60 minutes Benzodiazepine IM 15-30 minutes, oral is rapid Cooperation – therapeutic difference between IM and oral is relatively minor “Cheeking” oral meds Frequency - Reassessment every 15 minutes for patients in restraints, 30 minutes after IM injection and 30-60 minutes after oral meds Allen, MH: Managing the agitated psychotic patient: A reappraisal of the evidence. J Clin Psych 2000;61(suppl 14) 11-20.
Meta-analysis of drug studies Safety and tolerability Haloperidol – NMS, EPS Benzodiazepine – respiratory depression, dependence Measurement Brief Psychiatric Rating Scale Overt Aggression Scale Agitated Behavior Scale Drug selection – diagnosis, etiology, Route of administration, onset and duration Allen, MH: Managing the agitated psychotic patient: A reappraisal of the evidence. J Clin Psych 2000;61(suppl 14) 11-20.
Meta-analysis of drug studies Effectiveness – little difference in effectiveness accounted for by dose or kinetics Dosage 3 studies with haloperidol 7.4 mg – 41 mg produced 36-45% improvement Lesser dose produced intermediate response Allen, MH: Managing the agitated psychotic patient: A reappraisal of the evidence. J Clin Psych 2000;61(suppl 14) 11-20.
ED Study of Rapid Tranquilization Different from “rapid neuroleptization” Goal is alleviate anxiety, tension and motor excitement. Haloperidol 5 mg every 30-60 min IM 6 doses in 24 hours maximum No Level Dubin, WR, Feld, JA: Rapid tranquilization of the violent patient. Am J Emerg Med 1989: 7:313-320.
ED Study Prospective study of 98 agitated, aggressive patients over 18 months Used rapid tranquilization method Given IM lorazepam (2 mg), haloperidol (5mg) or combination Undifferentiated patients Haloperidol had more EPS symptoms No difference in sedation amongst the groups Did not evaluate BP between groups Most rapid RT with combination Level II Battaglia, J, Moss, S, Ruch, J, Et al: Haloperidol, lorazepam or both for psychotic agitation?

Combination Therapy Physical & Chemical Restraints Experts divided on whether patients who are calm in physical restraints need chemical restraint If there is continued agitation would add oral medication Relative safety of medication and physical restraints not studied
ED Process Case #1 Patient received a through history, physical examination and mental status examination No further laboratories were indicated Patient was given Haldol 10 mg and Cogentin 2.5 mg p.o. in the ED Diagnosis - Schizophrenia
ED Process Case #2 Patient received CBC, CMP, UA, dilantin level, head CT and lumbar puncture Dilantin level was 1.0 CT and LP were negative Patient was loaded with Dilantin and admitted for 23 hours of observation Diagnosis – Alcohol withdrawal syndrome
Take Home Point Medical Clearance process needs better definition or use of a protocol Short mental status exams better than current process Test patients with new onset on psychiatric illness Physical restraint is probably safe Chemically restrain with combination of haloperidol and lorazepam
