The Mild Traumatic Brain Injury Model of care in the Saguenay Lac
The Mild Traumatic Brain Injury Model of care in the Saguenay Lac St-Jean, Qc CSSS de Chicoutimi Guylaine Gobeil, clinical nurse adviser Serge Bergeron, MD Creation of the traumatology network in the province of Quebec at the beginning of the 1990s (the SAAQ being a key player) The MTBI model exists since1994 in the Saguenay Lac St-Jean Extension to the moderate and severe TBI in1999 (SAAQ) Report from the SAAQ in 2003 and the TASK FORCE in 2004 The SAAQ has stimulated the creation of a committee of medical advisers in neurotraumatology which meets regularly since 2003 Ministerial orientation for 2005-2010 Proposal to the regional committee for two models of organization A) Decentralization of the process by CSSS B) Centralization of the follow-up and screening at the CSSSC There has been a regional consensus for the second proposal Grouping of the medical advisers in neurotraumatology • Group of doctors working in the 10 neurotraumatology centre in the province of Quebec • Role : – Support for the diagnosis of TBI – Support for the coverage of TBI patients by the team of premature rehabilitation in neurotraumatology – Support for the development and preservation of the expertise in their center Grouping of the medical advisers in neurotraumatology • • • • • • • • • • • • • • Dr Jean-François Giguère, Hôpital du Sacré-Cœur de Montréal, responsable of the committee Dr Jeffrey Atkinson, Hôpital de Montréal pour Enfants (CUSM) Dr Serge B.

DIAGNOSIS OF TBI • Transfer of kinetic energy – Ischemia – Inflammation – Immunological reaction – Apoptose – Neurobiochemical perturbation – Modification in the permeability of cell membrane, including the hemato-encephalic brain barrier NEW DEFINITION OF MTBI • Eliminate all the others causes which may be responsible for the signs and symptoms (shock, medication, alcohol, drug, etc.) • Operational criteria : • Glasgow between 13 and 15 after 30 minutes or during the evaluation at the emergency • 1 of these signs: confusion, disorientation, loss of consciousness < 30 minutes, post-trauma amnesia < 24 hours, transient neurological signs including convulsion or a cranial or intracranial non-chirurgical lesion CARACTERISTICS CRANIOCEREBRAL TRAUMA CATEGORY OR GRAVITY MILD Duration of the loss or the alteration* of consciousness Result obtained on the Glasgow coma scale in the emergency or 30 min after the trauma Structural damage (fracture or intracranial brain lesion) 0 to 30 minutes maximum MODERATE Generally between 30 min and 6 h, but maximum duration of 24 h SEVERE Often > 24 h to several days, but necesseraly >6h 13 to 15 9 to 12 3 to 8 Positive or negative Generally positive Positive neuroimaging neuroimaging neuroimaging Neurological exam may Positive neurological Positive neurological Neurological exam be positive (possible exam (focal signs) exam (focal signs) focal signs) Variable, but generally Post-traumatic amnesia Variable but has to be between Several weeks < 24 h 1 and 14 days * The notion of a change of consciousness concerns essentially the mild trauma. Moderate and severe TBI are rather associated to an initial loss of consciousness of variable duration but which respect the indicated maximal durations. INCIDENCE • In Canada,11 persons on 100 000 severe TBI • Moderate-severe TBI 15% • MTBI represents 85% of all the TBI treated in a hospital environment • MTBI 300 on 100 000 of population • Two to three times more men than women nevertheless the causes or age groups • The frequency is sharply higher during the adolescence and at the beginning of adulthood (15-24 age group) CAUSES • • • • • Motor vehicle accident (+ ↑ Men) Fall (+ ↑ children (35%) and elderly) Sports (children 29%) Occupational accident Aggression 45 % 30 % 10% 10% 5% CAUSES OF REFERRED MTBI CASES 120 107 111 100 Women Men 88 Referred cases 80 68 60 51 42 40 32 28 27 23 20 10 10 10 0 0 Aggression Fall Objet Sport Motor vehicle Occupational Non accident documented Reference volume Region 02 by age group 180 170 160 140 MTBI 120 100 97 87 80 69 59 60 56 40 32 37 20 0 0 age 0-10 age 11-20 age 21-30 age 31-40 age 41-50 age 51-60 age 61-70 age 71 and Unknown up Consultation ADVICE GIVEN TO THE PATIENTS WHEN LEAVING THE EMERGENCY • Temporary symptoms; • Drowsiness, fatigue, fatigability, decrease of attention and concentration, headache, dizziness and nausea, irritability, anxiety • Frequent symptoms which can be disturbing especially during the first two weeks; • Rest and the management of energy; • Resume of the activities according to tolerance; ADVICE GIVEN TO THE PATIENTS WHEN LEAVING THE EMERGENCY • • • • • Supervision needed during the first 2 - 3 days; Information on MTBI; Reassuring on the favorable evolution; Medication as needed; Sick leave of work / study • Sick leave recommanded for 2 weeks • May be modified according to the evolution of the symptoms or the type of work / study ADVICE GIVEN TO THE PATIENTS WHEN LEAVING THE EMERGENCY • Come back to the emergency if ... • • • • Drowsiness is important and increasing; Uncontrollable headache; Persistent vomiting; Neurological signs appear (paresis, paresthesis, ataxia, convulsion, etc.). The emergency physician • Refer the client to the TBI program and inform the patient about it • • • • • Follow-up is essential + + +; Phone contact, support, playing-down of the symptoms; Energy and symptoms management; Sick leave and return to work management; Services and treatments management according to the evolution. Role of the clinical nurse manager in the TBI program • Assume the activites linked with the screening of MTBI (regional mandate) for an ambulatory clientele having been the objet of a case report to the Traumatology Program of the CSSSC; • Evaluate the state of health, determine and assure the realization of the nursing and interdisciplinary plan of the MTBI victims; • Advice and support the users in the management of the symptoms; • According to their needs, direct the victim of MTBI (and their family) to the members of the interdisciplinary team or to other actors of the health community; • Act as a ressource person for the users, the members of the team of care, the members of the interdisciplinary team and other local and regional partners; • Assure the continuity of care by establishing links of communication with all the involved participants (doctors, employees, school, environment,…); • Give some formation. Screening by the clinical nurse manager Cases may be reported to the Program by: - the emergencies of the several regional health centers - medical clinics - personnal initiative - SAAQ - health professionals Screening by the clinical nurse manager A- Call each referred client, ideally in the 7 days following the case report, in order to: 1. Proceed to the collection of data and complete the screening tool. 2. Look for convincing signs of TBI. 3. Look for the presence of factors which can negatively affect the prognosis. 4. Look for the presence of symptoms post-TBI. 5. Look for the presence of elements of acute stress. 6. Inform the users about TBI, acute stress and the management of the symptoms. 7- Reassure the users 8- Coordonate the Program 9- Elaborate the follow-up plan Screening by the clinical nurse manager B- Follow-up of the users by regular phone calls. C- If unfavorable evolution, orientation towards another professional according to the users needs - family physician - psychologist - occupational therapist - physiotherapist - social worker - emergency - medical adviser of the TBI Program - rehabilitation center D- Intervene with - teachers - employers Management of the symptoms Drowsiness: • Very frequent; • Allowed to sleep; • Make sure that the person remains arousable. Nausea and vomiting: • Rests often fix the problem; • Gravol can be used as needed (but can increase drowsiness); • Good food hygiene; – 3 meals a day – Regular hours – Follow the food guide Management of the symptoms Headache: • • • • • Rest and energy management are important; Provide relief to the symptoms, do not “endure“ them; Acetaminophen (ex: tylenol) vs Ibuprofen (ex: advil); Avoid the too noisy, too much lit or too hectic environment; Avoid alcohol or drug consumption. Sleeping disorder: • • • • • • Frequent and temporary; Good sleep hygiene; Hot milk; If the trouble persists, consult the family physician. Zopiclone Avoid benzodiazepines Management of the symptoms Fatigue and fatigability: • Frequent; • Variable in duration; • Progressive return to activities (school, work; facilitate temporary modifications of the work load); • Limit the time spent playing video games, using the computer or watching TV; • Respect threshold of energy; • Alternation of physical and cognitve activities; • More frequent rest period; • Avoid complete inactivity. Management of the symptoms Dizziness: • • • • Frequent; Avoid precarious positions (ex: height); Change position more slowly In presence of vertigo (presence of free otoliths) which can be frequent, vestibular therapy for example the Epley maneuvre. Attention-concentration-memory disorder: • Frequent • Dedramatise and normalise (put the acquaintance in the loop… use them as accomplices) • Use reminders (memo pads) • Do one thing at a time • Favor the places where stimuli are limited • Give oneself time to find back regular activities ACUTE AND PERSISTENT SYMPTOMS FREQUENTLY OBSERVED IN ADULTS Acute symptoms (0 to 3 months) • • Fatigue • Dizziness (mostly following • sport accidents) • Trouble sleeping Attention problem or decrease in • • the speed of treatment of the • information • Memory problem • • Headache • • • • • Persistent symptoms (0 to 12 months and more) Headache Fatigue Dizziness Trouble sleeping Attention problem Depression Memory problem Anxiety Irritability Other cognitive problems ACUTE AND PERSISTENT SYMPTOMS FREQUENTLY OBSERVED IN CHILDREN Acute symptoms* (0 to 3 months) •Headache •Fatigue •Attention problem or decrease in the speed of treatment of the information •Memory problem •Trouble sleeping •Light hyperactivity** Persistent symptoms * (0 to 12 months and more) •Light hyperactivity ** (followed for 5 years after the MTBI) •Negative prognosis has been noted in one study of a follow-up of a child 6 months after the MTBI (TDM + and deterioration > 24 h) •Other cognitive troubles (?) * These symptoms are generally less pronounced than in adults and have a shorter remission time period. ** This is the case in a study in which the authors conclude that it may be the result of the MTBI or conversely the MTBI being the result of light hyperactivity. Factors and level of risk of morbidity associated with MTBI Level of risk of morbidity High risk Low risk • Compensation problem • Ø compensation ( 50 %) • Age > 40 years problem • Age < 40 years • No previous history of • Neurological integrity neurological being already infringement compromised before the MTBI • Absence of previous stressors • Previous stressors • Gravity of the MTBI • (complex MTBI) Uncertain risk • Glasgow coma scale initial result at 13 • History of psychological, psychiatric or personnality disorder • Very young (<2 years) • Parents anxiety Diagnoses accompanying MTBI • Acute stress vs post-traumatic stress vs adaptation trouble vs previous stress; • Sprain cervical; • Other injuries, insomnia caused by pain or the hospitalization, etc.; • Neuropathic syndrome (fibromyalgia). SECOND IMPACT SYNDROME • While there are still some symptoms, another TBI occurs; • A smaller blow will give more symptoms and more aftereffects; • Ex. boxers, hockey players,etc.; • 35-40 deaths in athletes according to the literature between 1980 and 1993; • Morbidity 100%. Mortality > 50%. Resuming of sport activities • The Montreal Children Hospital has elaborated a tool “The concussion KIT “ – 5 steps: • Step 1: conditioning exercices; • Step 2: conditioning and specific habilities of the practised sport; • Step 3: conditioning and specific habilities of the practised sport; individually and with a teammate; • Step 4: conditioning and specific habilities of the practised sport; with the team (without contact); • Step 5: Complete training with contact. Resuming of sport activities • There should be at least 24 h (or more) in between each step; • If there is an inscrease or a return of the symptoms; stop training; • Rest; • Restart at the previous step; • Consult a physian if the symptoms persist or increase in intensity; • Resuming contact in the sport activity is only made when all the symptoms have disappeared. Prevention • Wear recommended, approved and well adjusted equipment (ex: helmet); • Promote team spirit and accept no violence; • Practise sport activities in zone planned for that purpose (ex: skate park); • Use adequately sport facilities (ex: soccer net); • Be visible during the evening; Prevention • Have the necessary habilities before increasing the level of difficulty of certain sport activities; • Make sure the depth of water in sufficient before diving; • Make sure that the equipments of the playgrounds are secure; • Make sure that the supervision is adequate in school playgrounds; • Respect the regulation when driving any motor vehicle. Guide for screening a TBI • Evaluate the presence of signs (confusion, amnesia, loss of consciousness, headache, nausea, vomiting, dizziness, loss of vision, ringing in the ears, drowsiness); • Ask question in order to evaluate the memory (How have you been hurt, where do we play, in which half are we, who scored the last goal, etc.); • Evaluate cognitive function ( 1: short term memory, ex: ask to memorize 5 words; 2: ask to spell the month backward; 3: ask to count backward; 4: ask the recall of the first 5 words). We should suspect a TBI in case of failure of any of these items. Medication being used in our patients… • The best means to manage the symptoms after a TBI, is to begin by avoiding that the brain is sub- or overstimulated. No medication is going to work if we do not manage the stimuli or the cognitive and physical efforts, if we do not alternate periods of stimuliactivities and rest, and if we do not mobilize the patient by adjusting to the threshold of fatigability where the symptoms appear (headache, dizziness, decrease of attention-concentration, increase of impulsiveness, nausea, etc.). Medication being used in our patients… • Amitriptyline at dinner time (for headache, pains and sleep quality) • Quetiapine (Seroquel) or Olanzapine (Zyprexa Zydis) (allows to decrease the impulsiveness, and facilitate the management of agitation and aggressiveness). • Zopiclone as a supplement to help sleeping (Zolpidem not being available in Canada and being used in Europe and the USA). Medication being used in our patients… • Avoid typical neuroleptic and benzo, except in the case of withdrawal problems, use oxazepam in minimal dose with Quetiapine and Thiamine. • For pharmacostimulation: amantadine or methylphenidate or modafinil Medication being used in our patients… • Venlafaxine for additional stimulation with or without amantadine, methylphenidate or modafinil , or for the treatment of anxiety problem or post-traumatic stress syndrome. • Mirtazapin in order to decrease anxiety or facilitate sleep. • Gabapentin, Pregabalin, Topiramate and other coanalgesics (for pain control) (adjust dosage in order to avoid adverse effects). • For nausea, avoid Stemetil (which is a typical antipsychotic), prefer Zofran, Gravol or Motilium (always having in mind that the basic treatment is the management of stimuli). • For vertigo: Serc and consider the Epley maneuvre. PROGNOSIS OF THE MTBI • Unfavorable outcome is not frequent after a MTBI, but may occur (2 to 1520% according to some studies). • The MTBI classification does not have any predictive power on a possible unfavorable outcome (trivial, simple or complex). Goal To make sure that the symptoms of the MTBI only remains a hard time to pass and without any functional aftereffects.
