Clinical practice guideline and pathways for the evaluation and management of patients with dizziness in family and community practice

ABSTRACT

Background@#Dizziness is a commonly encountered symptom in the primary care which can be caused, most of the time by benign condition and rarely due to serious conditions needing higher level of care.@*Objective@#To develop a clinical guideline and pathway that will serve as guide in the diagnosis and management of adult patients with dizziness in primary care and outpatient setting@*Methods@#A guideline development team was formed which is composed of family and community medicine specialists from different institutions. Searching, selection and assessment of the latest evidence on dizziness diagnosis and management was done using the search terms “dizziness”, “diagnosis”, “management”, and “primary care”. Formulation of the recommendation was done using Grade approach and graded with modified GRADEPro and expert panel consensus. External review was also done by an expert in otorhinolaryngology.@*Recommendations@#Clinical Assessment •Recommendation1.Askforthepatient’sdescriptionofdizzinessandclassifythepatientintooneofthefourtypes vertigo, presyncope, disequilibrium, and lightheadedness and classify as acute/episodic or chronic/sustained. (Strong Recommendation, Low Quality Evidence) •Recommendation2.Obtainamedicalhistoryfocusingonthetiming,triggers,associatedsymptoms,riskfactorsfor atherosclerotic vascular disease, and functional status or quality of life. (Strong Recommendation, High Quality Evidence) •Recommendation3.Performaphysicalexaminationfocusingonvitalsigns,HEENT(includingotoscopy),cardiovascular and neurologic examination. (Strong Recommendation, High Quality Evidence) •Recommendation4.PerformspecialphysicalexaminationslikeDix-Hallpikemaneuverforacuteepisodictriggeredvertigo to check for BPPV (most common cause of peripheral vertigo), HINTS plus test for spontaneous episodic vertigo to check for stroke and hyperventilation provocation test for patients suspected of anxiety (Strong Recommendation, High Quality Evidence) •Recommendation5.Elicitredflagsthatshouldwarrantreferrallikeseveredizzinessandassociated,alteredmentalstatus, loss of consciousness and abnormal vital signs. Other symptoms like chest pain, palpitations, dyspnea, neurologic deficit may warrant referral for evaluation and management. (Strong Recommendation, High Quality Evidence) •Recommendation6.Forpatientsconsultingviatelemedicine,obtainamedicalhistoryfocusingonthetiming,triggers, associated symptoms, risk factors for atherosclerotic vascular disease, and functional status or quality of life, and observe and conduct self-physical examination (vital signs, mental status, ocular and facial nerve) (Strong Recommendation, Low Quality Evidence) Diagnostic •Recommendation7.Laboratorytestingisnotroutinelyrecommendedamongpatientswithdizziness.However,testingmay be requested if there is a need to identify a definite etiology to guide treatment and should be guided by the classification of dizziness, possible etiology, and the medical history and physical examination. (Strong Recommendation, High Quality Evidence).Recommendation8.Forpatientswithvertigoandwithauditorysymptoms(i.e.,hearingloss,tinnitusandauralfullness, etc.), pure tone audiometry speech test may be requested if available. (Strong Recommendation, High Quality Evidence) •Recommendation9.Forpatientswithpresyncope/syncopeandachronicmedicalconditionisbeingconsidered,complete blood count may be requested for those with probable blood dyscrasia, serum blood glucose may be requested for those with diabetes, electrocardiogram and lipid profile may be requested for those with cardiovascular disease. (Strong Recommendation, High Quality Evidence) •Recommendation10.Forpatientswithdisequilibriumandwithanabnormalneurologicphysicalexaminationfinding,CT scan may be requested. (Strong Recommendation, High Quality Evidence) Pharmacologic •Recommendation11.Empirictrialofshortcourse(7days)pharmacologictreatmentforsymptomreliefshouldbeoffered. Referral should be considered if the dizziness become more severe or it did not improve in 7 days. (Strong Recommendation, High Quality Evidence) •Recommendation12.Forpatientswithmildtomoderatevertigo,offerhistamineanalogue(betahistine)orantihistamine (meclizine, diphenhydramine, dimenhydrinate or cinnarizine) for symptom relief. (Strong Recommendation, High Quality Evidence) •Recommendation13.Forpatientswithmildtomoderatevertigoassociatedwithmigraine(vestibularmigraine),aside from symptom relief, offer any of the triptans as preventive medication. (Strong Recommendation, High Quality Evidence) •Recommendation14.Forpatientswhosedizzinessisdescribedasdisequilibrium(gaitimbalance)orpresyncope(near faintness) or dizziness with anxiety attack, offer symptomatic treatment and intervention based on the underlying cause or consider referral to appropriate specialist. (Strong Recommendation, High Quality Evidence) Non-pharmacologic •Recommendation15.Allpatientsshouldbeprovidedwithhealtheducationoncauses,triggersandfollowup.(Strong Recommendation, Low Quality Evidence) •Recommendation16.Allpatientsshouldbeadvisedonappropriatedietandlifestylemodification.(StrongRecommendation, Low Quality Evidence) •Recommendation17.Dependingonthenatureofvertigo,educateandtrainthepatientoncanalrepositioningmaneuver and vestibular rehabilitation. Referral to rehabilitation medicine may be considered.

(Strong Recommendation, Expert Opinion)@*Implementation@#The committee shall disseminate the guidelines through presentations and via journal publications. The QA committee shall be in charge of implementation of the guideline and pathway.
