Describe the strategy/assessment re. substance use in ED setting
|
i) Obtain key info on substance use that is necessary for immediate management
Esp. important in: -Withdrawal state: important to assess if alc/sedative/opioid use is sufficiently high that a Withdrawal state may develop soon -Analgesia: hx of opioid use is important in gauging patien't analgesic requirement (e.g. if heroin dependent, usual doses of morphine is insuff) -Injection hx: potential infectious risk B) AMPLIFY -minor forms of substance use & their influence on clinical management & soc/occupational functions can wait until patient is Stabilized & Recovering from the Acute illness. -Hence, once stable&monitored for withdrawal states, need to amplify the alc/drug hx |
|

|
Techniques to Enchance Substance use Hx Taking
|
1) Normalize
-Introduce Substance use as a Normal, Everyday experience e.g. Alcohol -"many men like to have a good drink with their mates after a day's work" then give... 2) Permission: -...to talk about substance use e.g. "What do you like to drink, either after work or at other times?" 3) Assess Potential Symptoms: -e.g. to establish th epresence of Physical Dependence: -"Many regular drinkers feel shaky when they get up in the morning. When did you last feel like that?" 4) Suggesting High levels of Use -"Top-High" method: person is more likely to admit to their intake if several quantities at High end of the range of use are suggested --adjust for sex, socioeconomic background, any existing knolwedge about person's substance use --pay attention for Facial expression & Body Language during the interview --->often there is a Fleeting Look of recognition OR adoption of a Defensive body posture when the Correct intake is mentioned --such level is often Higher than the one the pat is prepared to admit verbally --If No acknowledgement, then progressively lower intakes in step-wise manner --When there is acknowledgement of certain intake level, Probe further to establish a Consistent resposne NB: important to pay attention to pat's rxn to this "Top-High" questioning because it may backfire badly. |

|
i) general Apperance:
-agitation (withdrawal state/stimulant use) -malnutrition (gaunt apperance) -premature aging (substance use) -Cushingoid facies (alcohol dependent) -arms covered with long sleeves in warm weather (injection mark) ii) signs of Intoxication: -garrulouseness (talkative) -unclear thinking -ataxia -smell of alcohol on breath iii) signs of Withdrawal -Hand: tremor & sweating -Face & Tongue: tremor iv) Cutaneous Stigmata of Alcohol & Drug use: -injection sites (antecubital fossae, back of the hand) -Conjunctival Injection = Recent heavy alcohol/cannabis use -facial Telangiectasia (alcohol) -Rhinophyma (alochol) -Inflamed Nsal Septum&Alae (cocaine) -Periorbital Wrinkling (tobacco smoking) -Skin Thinning (alcoho, heroin) -Dupuytren's contractures (alcohol) -Bruises, esp. of diff ages (alcohol, sedatives, opioids) -Scars unrelated to surgery (alcohol, opioids, psychostimulants) v) Cutaneous Stigmata of Liver disease e.g. Spider naevi, palmar erythema vi) CVS: Pulse rate & BP vii) CVD evidence: esp. valvular, endocarditis, cardiac hypertrophy, or failure viii) Abdo exam: Liver size& consistency; Splenomegaly; Ascites ix) evid of Head Injury x) CNS: Cranial Nerve esp.

NB: comment on formal cogntivie function testing |
PTEC
Perception: -esp. visual & auditory Thought -Paranoid ideation -Suicidal Ideation Emotion (affect, mood) -depression, anxiety, dysphoria, blunting, lability Cognition -Awareness of current events -Memory: immediate/short/long -Abstraction -Conceptualization -Planning NB: Formal cognitive function testing should await the resolution of any clouding of conciousness |
|
Limitation of Urine Drug Testing
|
-no info on freq or quantity (cf. history taking)
--can't assess likelihood of phsyical dependence, onset of withdrawal, dependence syndrome -"-ve despite recent use" when substances are cleared rapidly from the body --exceptions are: -Long-acting BDZ (e.g. diazepam): metabolites detectable for several Days -Cannabis (THC): detectable in urine & serum for several weeks |
|
Collateral Info:
-source -purpose -NB |
Source:
-relative -friends -involved professionals -hospital/GP medical records Purpose: -reliability check -indep persepective -free from llimitation due to acute intoxication or neuropsychological impairment NB: -must be obtained with patient's permission -any limitations or concerns about ethical issues are addressed (e.g. divulging info to the parents of an adolescents) --UNLESS: prompt diagnosis outweighs privacy concerns e.g. severe psychotic symptoms, accidental OD -useful when pat shows strong denial of substance use disorder --CAREFUL: avoid patient becoming alienated by solicitation of this info |
|
Typical Presenting Complaint for:
-BDZ -Opioids |
BDZ:
-anxiety -"tension" -insomnia NB: difficult to assess if it is genuine or not Opioids -acute/chronic pain esp. Renal colic, Migraine, chronic Back pain |
|

|
Alcohol History taking Strategy
|
1) Approach: Convenient&Acceptable to pat
by introducing with other lifestyle issues e.g. "We often find that people's eating, smoking and drinking habits may have sig impact on their Health or how they Feel about themselves. I'd like to ask you some questions in these areas" 2) Normalize as everyday experience: "Most of us like to have a drink on a regular basis. How often would you have a drink during the week and at the weekends? 3. High-Top question: i.e. suggest high levels of drinking to patient e.g. two dozen beers a t asitting, a bottle of gin a day ->this way, person is more likely to admit to a high intake; and allows pat to correct you downwards (choose high value depending on sex, socioeconomic background, existing knolwedge about erson's alcohol consumption) 4) Don't let personal attitudes affect assessment: -sometimes under-dx is due to Dr's own denial mchanisms (Dr's own problems with alcohol) -Judgemental attitudes 5) Avoid Labels e.g Alcoholic -Use terms:"drinking problem" or "problems related to alcohol" -Unless the pat feels comfortable using that term -If pat feels accused of being an alcoholic, pat may become defensive, be frightened away from tx 6) Home-poured drinks: -tendency to underestimate the size of home-poured drinks -try to estimate specific amount of alcohol consumed e.g. half a bottle of wine (cf. 4 glassfuls??) 7) Motivation for Change -assess state of change by asking direct Qu's about change (interest, need, want, "other", confidence) e.g. "How Interested are you in changing your (substance) use now? "Do you feel that you Need to stop using (substance)?" "Do you really Want to stop using? (substance)" "What do you feel you could do to get on top of your use of (substance)?" "How Confident are you that you could achieve this?" |
