  2. Have you heard?? There are new changes to the Alcohol Withdrawal Protocol!

  3. Review

  4. Definition of Alcohol Withdrawal Syndrome • Alcohol Withdrawal Syndrome is characterized by central nervous system hyperactivity that occurs when an alcohol dependent individual abruptly stops or significantly reduces alcohol consumption. • Alcohol Withdrawal Syndrome encompasses symptoms that can range from mild to life threatening delirium!

  5. Today, it is estimated that one in four people are classified as “at-risk” drinkers. These individuals meet the criteria for alcohol abuse or dependence. • Many times, a patient is not even aware themselves that they are considered at risk for alcohol abuse or are indeed alcohol dependent! • You, as the healthcare provider, may come in contact with patients who are alcohol dependent without being aware of it when you first care for them!

  6. About 50% of alcohol - dependent patients develop clinically relevant symptoms of withdrawal! • If you are not looking for Alcohol withdrawal, the symptoms can easily be overlooked. • Because deaths have occurred in 10% of untreated alcohol withdrawal delirium and in 25% of those patients with medical or coexistent surgical complications, it is imperative to be on the alert for this life-threatening condition! • (Stern: Massachusetts General Hospital

  7. The stigma and ignorance about alcoholism unfortunately contribute and affect two major in–patient problems: Under recognition & Inadequate treatment

  8. American Society of Addiction Medicine Guidelines for Proper Treatment of Withdrawal • Provide a safe withdrawal from the drug(s) of dependence and enable the patient to become drug free • Provide a withdrawal that’s humane and protects the patient’s dignity • Prepare the patient for ongoing treatment for the dependence

  9. Its important to remember ……… If interventions don’t get implemented early on – withdrawal symptoms are more likely to become more severe and may progress to: • Hallucinations • Seizures • Delirium tremens

  10. Withdrawal symptoms can also progress and include: • Arrhythmias • Pneumonia • CNS injury • Exacerbation of underlying pancreatitis or hepatitis

  11. Remember, every patient will differ as to how much and when they will experience if, any withdrawal symptoms!Our goal is to recognize who is at risk and prevent!

  12. Signs and symptoms team members need to be alert and watch for include…….

  13. Mild Symptoms of Alcohol Withdrawalcan occur within hours; 6-12 hours of stopping orlowering BAC (blood alcohol concentrations)

  14. Mild Symptoms • Anxiety • Insomnia • Vivid dreams • Tremors • Headache • Diaphoresis • Palpitations • Anorexia • Gastrointestinal upset- Nausea and Vomiting • Hypervigilance

  15. More serious symptoms may present anywhere within 12- 96 hours

  16. Within 12 to 24 hours, the patient may also experience… • Visual hallucinations • Tactile hallucinations • Auditory hallucinations – although not as likely

  17. Withdrawal Seizures may develop between 6 and 48 hours after the patients last drink of alcohol… Seizures are the highest safety risk for patients in alcohol withdrawal because of the: Risk for aspiration Oxygen deprivation Physical injury from thrashing Once again, those patients who have experienced repeated episodes of alcohol withdrawal increase their risk for withdrawal seizures. It is important to get treatment early to prevent status epilepticus

  18. Within 48 to 96 hours, the patient may experienceAlcohol Withdrawal Delirium • Delirium • Tachycardia • Hypertension • Low-grade fever – below 100.7F • Agitation • Diaphoresis • Fever greater than 100.7F is not withdrawal related and must be evaluated for infectious source

  19. Your patient is at risk for Alcohol Withdrawal Delirium if any of these factors are present: • Severe withdrawal symptoms • History of heavy alcohol use (more than five standard drinks a day for men; more than four standard drinks a day for women) • History of alcohol withdrawal delirium or withdrawal seizures which leads to “Kindling phenomena” • Abnormal liver function • Advanced age

  20. “Kindling” occurs when a patient has experienced repeated cycles of intoxication followed by abstinence

  21. The patient’s neurons undergo long term changes, causing subsequent episodes of withdrawal to worsen! The chemical imbalances become more pronounced and this patient is more likely to rapidly experience seizures in the absence of alcohol.

  22. Alcohol Withdrawal Protocol • All patients are considered eligible for the alcohol withdrawal protocol if a history of alcohol withdrawal delirium tremors or a positive alcohol history or symptoms. • The CIWA-Ar protocol is used to assess and treat patients who may be in/at risk for alcohol withdrawal. • Initiation of this protocol is suggested for patients evaluated to be at risk during the hospital stay to avoid the complication of alcohol withdrawal.

  23. Initiating the Alcohol Withdrawal Protocol • During the admitting process, each patient will be asked if they have a history of alcohol use and /or a prior history of alcohol withdrawal. • After discussion with the physician about the history, the physician may order the protocol for alcohol withdrawal order set. • The nurse will monitor the patient using the Alcohol (CIWA-Ar Flow sheet).

  24. The CIWA-Ar Scale • Utilizing a standardized monitoring tool for alcohol withdrawal is key to: • Preventing excess morbidity and mortality in patients who are at risk for alcohol withdrawal; • Helping clinical personnel recognize the process of withdrawal before it progresses to more advanced stages; • Intervening with appropriate medications to alleviate symptoms of withdrawal.

  25. CIWA - Ar tool Uses both nursing observation (tremor-sweats-agitation-orientation) and patient’s reports or answers (to 6 other questions the nurse will ask patient to elicit patient experiences of the symptoms which include: anxiety, headache fullness in head, nausea and vomiting- tactile disturbances-auditory disturbances-and visual disturbances being evaluated)

  26. The CIWA-Ar has well-documented reliability, reproducibility and validity, based on comparison to ratings by expert clinicians. • The CIWA-Ar scale can measure 10 symptoms (maximum possible score 67). • The assessment requires approx. 5 minutes to perform.

  27. CIWA-Ar Assessment Parameters

  28. Nausea & Vomiting • Ask: Do you feel sick to your stomach? Have you vomited?” Score appropriately: • 0 No nausea and no vomiting • 1 Mild nausea with no vomiting • 2 • 3 • 4 Intermittent nausea with dry heaves • 5 • 6 • 7 constant nausea, frequent dry heaves

  37. Orientation and clouding of sensoriumAsk “What day is this? Where are you? Who am I? • 0 oriented and can do serial additions • 1 cannot do serial additions or is uncertain about date • 2 disoriented for date by no more than 2 calendar days • 3 disoriented for date by more than 2 calendar days • 4 disoriented for place and/or person

  38. CIWA-Ar Scoring 1. The total of the number of points accrued from these 10 parameters will give you the CIWA-Ar score of your patient. 2. The nurse will score the patient on the flow sheet each time the assessment is completed. 3. Some of the assessment criteria is objective. Two different nurses may scoring the patients at the same time might have slightly different scores. However should not be large discrepancies between the two score. 4. Follow orders per physician in the CIWA-Ar order set.

  39. The Alcohol Withdrawal Protocol itself consists of: Physician orders: Activity level: Up to chair and bathroom privileges as tolerated when awake, responsive and stable. Oxygen per nasal cannula to maintain O2 saturation 93% or greater

  40. Physician's Orders: LABORATORY: RUN ALL LABS “STAT” • Magnesium Level (Serum) • Comprehensive Metabolic Panel • Partial thromboplastin time (aPTT ) (blood) • Prothrombin time/international normalized ratio PT/INR) (blood) • CBC • Alcohol (ethanol), quantitative (blood) • Drugs of abuse, qualitative (urine) • Methanol, qualitative, (blood) Ingestion suspected

  41. New Scoring Guidelines! • Minimal to Mild Withdrawal: Less than 6 or below • Moderate Withdrawal: 6-15 • Severe Withdrawal: 15 or more (impending delirium tremens).

  42. Frequency of Vital Signs and CIWA-A assessment: • If CIWA-A is less than 6, then repeat score and vital signs every 4 hours until less than 6 (x 4 scores, then discontinue protocol) • If CIWA-A score is greater than 6 - Nurse is to perform vitals signs and CIWA-A assessment hourly until score is less than 6.

  43. Frequency of Vital Signs and CIWA-A assessment continued: • If CIWA-A score remains greater than 6 x 72 hours - notify the physician! • If CIWA-A score is greater than or equal to 20, notify physician and obtain order to transfer to ICU if appropriate.

  44. CIWA-Ar Algorithm CIWA-Ar SCORE and Vital SignsFrequency Greater than 8 Greater than or equal to 20 Less than 6 6 or Greater Greater than 8 x 72 hours, notify physician. Greater than or equal to 20, notify physician and obtain order to transfer to ICU if appropriate. Repeat CIWA-Ar score and Vital Signs Every 4 Hours until score is less than 6 X 4 scores and then discontinue protocol. Repeat CIWA- Ar score and Vital Signs Hourly until score is less than 6. Call physician if patient has CIWA-Ar score greater than 8x72 hours or greater than or equal to 20. Or if Vital Signs: HR>110/min., DBP>120 mmHg, or SBP >180 mmHG

  45. Call Physician if patient has: Heart rate greater than 110 Diastolic Blood Pressure (DBP) greater than 120mm Hg or Systolic Blood Pressure (SBP) greater than 180mm Hg

  46. Medication Change Depending upon the which criteria your patient falls under, the new protocol will use either Diazepam (Valium) or Lorezapam (Ativan)

  47. Is there serious liver disease(PT/INR > 13 sec)? Is there serious pulmonary disease(FEV1 < 1.5 liters)? Is the patient elderly? NO YES Diazepam (Valium) 5mg intravenously, *reassess CIWA-Ar in 1 hour* Repeat dose every 1 hour if CIWA-Ar score is above 6 Lorazepam (Ativan) 2mg intravenously, reassess CIWA-Ar in 1 hour, Repeat dose every 1 hour if CIWA-Ar is above 6.

  48. Medication Changes: • Dosing is still based on the CIWA-A score range. • The medication frequency has changed to every 1 hour for CIWA-A score above 6 and vital signs taken every hour until score is less than 6 .

  49. Medications (as found on Physician’s orders) • Discontinue all previous benzodiazepine orders BENZODIAEPINES: IF CIWA-Ar score is greater than 6, CHOOSE ONE: Recommended treatment for withdrawal for most patients: • Diazepam (Valium) 5mg intravenously, *reassess CIWA-Ar in 1 hour* Repeat dose every 1 hour if CIWA-Ar score is above 6

  50. For patients with advanced cirrhosis, INR greater than 1.3 or age greater that 60; Choose: • Lorazepam (Ativan) 2mg intravenously, reassess CIWA-Ar in 1 hour, • Repeat dose every 1 hour if CIWA-Ar is above 6.
