CLINICAL PRACTICE GUIDELINES

PRACTITIONERS
CLINICAL PRACTICE GUIDELINES
FOR PRACTITIONERS
This combined reference has been developed as an educational tool by a statewide, interdisciplinary panel of providers, in collaboration with Blue Cross and Blue Shield of Missouri. It is intended to identify leading “best practices” and help practitioners reduce variation in practice patterns. It is not intended to include all possible methods of care for a particular condition, to identify all criteria for recommending a specific procedure, or to be a required treatment of a particular condition.
The practitioner, at his/her discretion, is expected to exercise reasonable clinical judgment regarding the care each patient needs. Individual patient circumstances should always be taken into account. These guidelines are intended to serve as a foundation for a continuous process of collaboration with physicians and allied health providers to maintain and advance the knowledge base associated with “best practices”.
Each of the Guidelines is based on recommendations from recognized specialty societies (i.e., ACOG, ACOG, AAFP, ACC, AAP, ACP-ASIM), national organizations (i.e., American Cancer Society, American Heart Association, March of Dimes), and governmental entities (i.e., U.S. Department of Health and Human Services, the Centers for Disease Control and Prevention). An external panel of BCBSMo physicians and the BCBSMo Quality Improvement and Physician Review Committee (QIPRC) reviewed the revised guidelines on the basis of content, clarity and appropriateness.
We hope you will find this manual useful in your practice. Information regarding current issues will be provided from time to time through guideline updates and periodic mailings. We invite your comments and suggestions. Please direct your communications to:

Induction of Labor
ACOG Dating Criteria for term gestation:
•Fetal heart tones documented for 20 wks by non-electronic fetoscope or for 30 wks by Doppler•36 weeks since positive serum or urine HCG pregnancy test was performed by a reliable laboratory•An U/S measurement of crown-rump length, obtained at 6-12 weeks, supports a gestational age of at least 39 wks•An U/S obtained a 13-20 weeks confirms the gestational age of at least 39 weeks determined by clinical history and physical examination
Indications for inducing labor may include:•Pregnancy-induced hypertension, pre-eclampsia, or chronic hypertension•Premature rupture of membranes•Chorioamnionitis•Suspected fetal jeopardy (i.e. fetal growth restriction, isoimmunization)•Maternal medical problems (i.e. DM, renal disease, chronic pulmonary disease)•Fetal demise•Logistical factors (i.e. risk of rapid labor, distance from the hospital, psychosocial indications)•Postdate pregnancy•Oligohydramnios•Abruptio placentae
Consideration of Labor Induction
Do benefits
to mother andfetus outweigh therisks of continuing
the pregnancy?
no
Reconsider Induction
yes
Iscervix
favorable?no Repeat doses of
ripening agent as appropriate
Proceed with amniotomy and/or oxytocininduction (10U of oxytocin in 1 L of IV solution) as appropriate.
Does thepatient meet
dating criteriafor term?
yes
Initiate cervical ripening (if appropriate) with one of the following:•IV Oxytocin (Pitocin)--0.5-6 mU/min initial dose (max 25mU/min)•Intracervical Dinoprostone gel (Prepidil)--0.5 mg initial dose, may repeat q6 hours (maximum of 3 doses in 24 hours)•Intravaginal Dinoprostone insert (Cervidil)--10 m (once only)•Intravaginal Misoprostol* (Cytotec)--25 ug initial dose, may repeat q3-6 hours (maximum of 6-8 doses) Wait at least 4 hours to begin oxytocin.Other options for cervical ripening include: stripping of the membranes,amniotomy, balloon catheters
Absolute contraindications for inducing labor include:•Placenta or vasa previa•Transverse fetal lie•Prolapsed umbilical cord•Previous transfundal uterine surgery•Active genital herpes infection•Pelvic structural abnormality•Invasive cervical cancer
Obstetric conditions that may require special care during induction (relative contraindications):•Mulitfetal gestation•Polyhydramnios•Maternal cardiac disease•Abnormal fetal heart rate patterns not requiring emergency birth•Grand mulitparity•Severe hypertension•Breech presentation•Presenting part above the pelvic inlet•One or more previous low-transverse cesarean deliveries
yes
no
Consider Bishopscore (see page 2)
Isinduction
likely to besuccessful?
no
yes
*Do not use Misoprostol in patients with prior c-section or major uterine surgery.
Fetal heart rate and uterine activity should be continuously monitored from the time the PGE2 vaginal insert is placed until at least 15 minutes after it is removed

Bishop System of Cervical Scoring (Table from Harman et al)
Note: Add the score for each of the clinical assessments. If the total score is greater than 8, the success of induction approaches that of spontaneous labor. A Bishop score of "5 is associated with induction failure.
Possible complications associated with oxytocin infusion include:
•Uterine Hyperstimulation --> uterine contractions more often than every 2 minutes that lastlonger than 90 seconds with or without fetal heart changes. Excessive uterine contractions may lead to uteroplacental hypoperfusion and fetal hypoxia, uterine rupture, or abruptio placentae. Hyperstimulation may be treated by decreasing or stopping the oxytocin and with administration of terbutaline 0.125 mg IV or SC.
•Water Intoxication --> because of its similarity to pituitary antidiuretic hormone (ADH), large doses can result in water intoxication that can lead to hyponatremia, confusion, convulsion, coma, congestive heart failure, and death. To avoid this complication, monitor intake and output closely and use oxytocin judiciously.
•Uterine Rupture --> occurs more commonly in multiparous patients, in those with previous uterine scar, with fetal malpresentations, and with multiple pregnancy or overdistended uterus. These conditions are relative contraindications to oxytocin use.
•Other complications of oxytocin infusion include: abruptio placentae, precipitous delivery, postpartum uterine atony and hemorrhage, neonatal hyperbilirubinemia, hypotension, and amniotic fluid embolism.
Physician focus for managing labor induction:
• Discuss risks/benefits with women considering induction and document in chart.• Confirm adequate fetal dates prior to induction and document in chart.

Non-Reassuring Fetal Status
Non-Reassuring Patterns:
• Fetal tachycardia• Fetal bradycardia• Saltatory variability• Variable decelerations associated
with a non-reassuring pattern• Late decelerations with preserved
beat-to-beat variability
Ominous Patterns:
• Persistent late decelerations with loss of beat-to-beat variability
• Non-reassuring variable decelerations associated with loss of beat-to-beat variability
• Prolonged severe bradycardia• Sinusoidal pattern• Confirmed loss of beat-to-beat
variability not associated with fetal quiescence, medications or severe prematurity
Labor with ElectronicFetal Monitoring (EFM)
ReassuringFHR pattern?
no
Continuelabor monitoring

yes
ReassuringFHR
pattern?
no
Vaginal delivery
Perform Cesarean Section
yes
Emergency Interventions for Non-reassuring Patterns:
• Check maternal blood pressure - if hypotensive and epidural in place, administer IVF bolus
• Change maternal position (lateral or knee-chest)• Call anesthesia to evaluate, if no improvement• If no epidural, give IVF bolus, and reposition - if no
improvement, evaluate for cause of maternal hypotension• Consider tocolysis (for uterine tetany or hyperstimulation)• Decrease or discontinue oxytocin if infusing• Consider amnioinfusion (for variable decelerations)• Determine whether operative intervention is warranted and, if
so, how urgently it is needed
Deliveryimminent?
no
yes
Fetal Heart Rate (FHR) tracing should be interpreted ONLY in the context of the clinical scenario, and any therapeutic intervention should consider the maternal condition as well as that of the fetus.
Non-Reassuring Fetal Status p.2
Causes of Fetal Tachycardia:• Fetal hypoxia• Maternal fever• Hyperthyroidism• Maternal or fetal anemia• Parasympatholytic drugs
•Atropine•Hydeoxyzine (Atarax)
• Sympathomimetic drugs•Ritodrine (Yutopar)•Terbutaline (Bricanyl)
• Chorioamnionitis• Fetal Tachyarrhythmia• Prematurity
Signs of Non-Reassuring Variable Decelerations that Indicate Hypoxemia:• Increased severity of the deceleration• Late onset and gradual return phase• Loss of “shoulders” on fetal heart rate (FHR) recording• A blunt acceleration or “overshoot” after severe deceleration• Unexplained tachycardia• Saltatory variability• Late decelerations or late return to baseline• Decreased variability
Causes of Severe Fetal Bradycardia:• Prolonged cord compression• Cord prolapse• Tetanic uterine contractions• Paracervical block• Epidural and spinal anesthesia• Maternal seizures• Rapid descent• Vigorous vaginal examination
Physician focus for managing non-reassuring fetal heart rate (FHR) patterns: • Emphasize appropriate emergency interventions for non-reassuring or ominous fetal heart rate patterns.

Fetal Macrosomia
Risk Factors for Fetal Macrosomia:
•Maternal diabetes•Maternal impaired glucose intolerance•Multiparity•Previous macrosomic infant•Prolonged gestation•Maternal obesity•Excessive maternal weight gain•Male fetus•Parental stature•Maternal age•Maternal race•Paternal birth weight•Need for labor augmentation•Prolonged second stage
# Prepare and drill labor and delivery staff in the basics and management of shoulder dystocia, including:
⇒ McRoberts maneuver⇒ Suprapubic pressure on the
impacted shoulder⇒ Wood’s maneuver⇒ Delivery of the posterior arm⇒ Zavanelli maneuver
“To date, no management algorithm involving selective interventions based on estimates of fetal weight has demonstrated efficacy in reducing the incidence of either shoulder dystocia or brachial plexus injury…planned interventions based on estimates of fetal weight do not reduce the incidence of shoulder dystocia and do not decrease adverse outcomes attributable to fetal macrosomia.”
--Sacks and Chen, Obstetrical and Gynecological Survey 2000“Current guidelines state that a planned cesarean delivery for a diabetic pregnant woman whose fetal weight estimates exceed 4250 to 4500 gm may be reasonable...”
--ACOG Practice Patterns Number 7, October 1997“With an estimated fetal weight greater than 4500 gm, a prolonged second stage of labor or arrest of descent in the second stage is an indication for cesarean delivery”
--ACOG Practice Bulletin Number 22, November 2000“For almost all macrosomic pregnancies including diabetic mothers, previous deliveries with shoulder dystocia, or women considering VBAC, expectant management with vigilance for evidence of fetopelvic disproportion will have optimal results.”

Vaginal Birth after Cesarean Section(page 2)
Special considerations of labor management for VBAC candidates:
•C-section team should be available within a short time (20-30 min).•Intermittent auscultation or continuous electronic fetal heart rate monitoring should be done.•Augmentation or induction of labor is not contraindicated.•Uterine scars do not require manual exploration post-partum.•Epidural anesthesia is not contraindicated.•Amnioinfusion is not contraindicated•Intrauterine pressure catheters are not necessary unless there are other obstetric indications.•The use of prostaglandins in women with previous c-sections has not been thoroughly studied. Each situation should be weighed individually.
The following are NOT contraindications to VBAC:
•Two or more previous C-sections•Previous failure to progress in labor and/or CPD•Post C-section infection•Vaginal delivery with a known overdistended uterus (i.e., twins, macrosomia, hydramnios)
Physician focus for Vaginal Birth after C-section (VBAC):
• Discuss risks/benefits of VBAC with patient and document in chart• Document prior uterine surgeries, including c-section(s) in patient’s chart.• Facilities are encouraged to have a general VBAC policy that is agreed on by the obstetrics and
gynecology department, with a built-in monitoring and evaluation system.

Pregnancy-Associated Hypertensive Disease
Findings suggestive of preeclampsia syndrome:
•Blood pressure>=160 systolic or >=110 diastolic•Proteinuria of 2.0 g or more in 24 hours (2+ or 3+ on qualitative examination)•Increased serum creatinine (>1.2 mg/dL)•Platelet count less than 100,000 cells/mm3 and/or evidence of microangiopathic hemolytic anemia•Elevated hepatic enzymes (ALT or AST)•Pulmonary edema•Oliguria - <400cc/240•Intrauterine growth retardation or oligohydramnios•Persistent headache or other cerebral or visual disturbances•Persistent epigastric pain
Hypertension inpregnancy
(>140/90 mmHg on two or more
determinations)
Always carefully consider the risks and benefits to a woman and her fetus with continuing or initiating pharmacotherapy for hypertensive disease during pregnancy. Antihypertensive treatment for mild chronic hypertension benefits the mother, but the impact on perinatal outcomes is less clear.
HTNdiagnosedbefore 20
weeks gesta-tion?
no•Consider reducing dose or weaning current regimen. ACE-Inhibitors and Angiotensin II Receptor Blockers MUST be discontinueddue to risk of fetal abnormalities. •If SBP >=150 mmHg or DBP >=100 mmHg and treatment has not yet been initiated, see page 2 for options•Consider work-up of secondary hypertension
Ispatient at
<32 weeks’gestation?
Attempt to postpone delivery if hypertension is mild, and no renal, liver, or coagulation abnormalities are evident.
yes
no
Continue close observation of woman and fetus. Initiate antihypertensive therapy if/when benefits to mother appear to outweigh risk to fetus.
Pre-eclampsiasymptomsor signs present?
yes
Consider corticosteroids to accelerate fetal lung development.
Likely chronic hypertension
The use of alcohol and tobacco during pregnancy should be strongly discouraged.
yes
no
Consider labor induction
yes
no
Hospitalize patient and monitor closely for signs of fetal distress and symptoms of headache, visual disturbances, and right upper quadrant pain
Consider initiation of antihypertensive agent if DBP is 100 mmHg or higher
Haspatient
experienced severehypertension
for 24-48 hours? ORDoes patient have another qualifying
diagnosis?
•Continue close observation and monitoring of woman and fetus•Bed rest•Antihypertensive medications•Magnesium sulfate for seizure prophylaxis
Qualifying diagnosis for labor induction when pregnancies are at or near term:
•HELLP syndrome•Progressive renal failure•Premonitory signs of eclampsia (including
mild)•Elevated blood pressure•Fetal distress
Administer magnesium sulfate for seizure prophylaxis during labor and delivery and for at least 24 hours post-partum by continuous IV infusion.
Consider bed rest
Outpatient management may be considered if compliance is expected to be good, hypertension is mild, and the fetus is normal.
Monitor deep tendon reflexes, respiratory rate, and urinary output during magnesium sulfate administration
Pregnancy-Associated HypertensiveDisease (page 2)
Antihypertensive Drugs Used in Pregnancy (from NHLBI*):
Suggested Drug CommentsCentral alpha-agonist Methyldopa is the drug of choice recommended by the NHBPEP** Working Group.
Beta-blockers Atenolol and metoprolol appear to be safe and effective in late pregnancy.Labetalol also appears to be effective. Beta-blockers can cause IUGR and lowplacental weight when used during the second trimester. Other potentially adverseeffects include fetal bradycardia, impaired fetal compensatory response to hypoxia,and neonatal hypoglycemia.
Calcium antagonists Potential synergism with magnesium sulfate may lead to precipitous hypotension.
ACE-Inhibitors, Fetal abnormalities, including death, can be caused, and these drugs should not beAngiotensin II receptor blockers used in pregnancy.
Diuretics Diuretics are recommended for chronic hypertension if prescribed before gestationor if patients appear to be salt-sensitive. They are not recommended in preeclampsia.
Direct vasodilators Hydralazine was the parenteral drug of choice, but is being replaced by IV labetalolor oral /SL nifedipine based on fewer maternal and perinatal adverse effects.
Conditions Sometimes Confused with Preeclampsia or Eclampsia:
•Viral hepatitis•Acute fatty liver of pregnancy•Acute pancreatitis•Gallbladder disease•Appendicitis•Kidney stones•Glomerulonephritis•Hemolytic-uremic syndrome•Exacerbation of systemic lupus erythematosus•Autoimmune thrombocytopenia•Thrombotic thrombocytopenic purpura•Cerebral venal thrombosis•Encephalitis of various causes•Cerebral hemorrhage
Laboratory tests to consider in early gestation for women who are “High-risk” for preeclampsia*** or who present with hypertension before gestation week 20:•CBC•serum creatinine and uric acid levels•24-hour urine collection for protein and creatinine IF routine urine analysis shows 1+ or greater protein with clean catch specimen•Early sonogram for dating if conditions not optimal for clinical dating•Baseline sonogram for evaluating fetal growth at 25 to 28 weeks
*NHLBI, National Heart, Lung, and Blood Institute (a division of the NIH).
**NHBPEP, National High Blood Pressure Education Program
***High-risk for preeclampsia includes a history of increased blood pressure before conception or in a previous gestation; women with diabetes, collagen vascular disease, or underlying renal vascular or renal parenchymal disease; and those with a multifetal pregnancy.
Laboratory evaluation for women who develop hypertension after gestation week 20--at initial diagnosis of hypertension, and consider repeating biweekly:•CBC•protein excretion quantification (e.g., 24-hour collection)•serum creatinine, uric acid, and transaminase levels•serum albumin, lactic acid dehydrogenase, blood smear, and coagulation profile
Hypertension
*Consider simultaneous initiation ofpharmacotherapy if patient is a diabetic or has signs/symptoms of end-organ damage.**B-blockers should not be started during an acute worsening of clinical status or when patient has fluid overload. FDA-approved B-blockers for CHF include Carvedilol (Coreg), Bisoprolol (Zebeta) and Metoprolol succinate (Toprol XL)
Goal blood pressure:<140/90 for adult without diabetes<130/80 for adults with diabetes

Focus on the Patient:• Simplify medication regimens• Provide explicit patient instruction and use good counseling techniques to teach the patient how to follow the
prescribed treatment• Encourage the use of prompts to help patients remember treatment regimens• Use systems to reinforce adherence and maintain contact with the patient• Encourage the support of family and friends• Reinforce and reward adherence• Increase visits for patients unable to achieve treatment goal• Increase the convenience and access to care• Involve patients in their care through self-monitoring
Drug Class Indication Cautions/ContraindicationsStatins(HMG-CoAreductase inhibitors)
• Drug of choice in patients with knownCAD
• Reduces LDL-C 25-40%• Reduces triglyceride levels• Modest increase in HDL-C• Demonstrated decreased mortality from
CAD
• Contraindicated in active liver disease• Hepatotoxicity occurs in <2% of
patients, and is usually reversible• Myositis is unusual complication• Caution when combining with
fibrates or niacin
Bile AcidSequestrants(Cholestyramine andcolestipol HCl)
• Typically first-line for primaryprevention (hyperlipidemia withoutknown CAD)
• Can reduce total cholesterol and LDL-C 15-30%• Increases triglyceride levels• Can be combined with other drugs (e.g.
statins)for severe forms ofhypercholesterolemia
• Gastrointestinal side effects maypreclude or limit dosage
Niacin(i.e. Nicotinic acid,Niaspan)
• Reduces LDL-C cholesterol andtriglycerides
• Increases HDL-C levels
• Contraindicated in chronic liverdisease, severe gout
• Relative contraindication with pepticulcer disease
• Flushing is common side effect. Thismay be alleviated by titrating dose,taking with a meal and/orpretreatment with aspirin
• Requires monitoring of liver function
Fibrates(i.e. gemfibrozil)
• Reduces triglyceride levels—mostvaluable for treatment of very hightriglyceride levels
• May elevate both LDL-C and HDL-Clevels
• Can use as combination therapy with astatin for mixed lipid abnormalities—monitor for myopathy and potentialhepatic toxicity
• Doesn’t usually produce substantialLDL-C reduction
• May elevate both LDL-C and HDL-Clevels
• Myositis and gallstones are unusualcomplications
• Contraindicated in severe renaldisease, severe hepatic disease
EstrogenReplacementTherapy
• Should be considered as a possiblealternative or adjunct to therapy forwomen with elevated LDL-cholesterollevels
• Increases HDL-C levels• Reduces LDL-C levels
• Combine with progestins for womenwith intact uterus
Physician focus for Treating Hyperlipidemia:
• Select a statin for lipid-lowering therapy in patients with known coronary artery disease (CAD). Indicator: Percentage of adults diagnosed with hyperlipidemia with a co-existing diagnosis of
CAD or MI that are treated with a statin.
• See patients diagnosed with hyperlipidemia for office follow-up within 4 months of initial diagnosis.

General Contraindications for Exercise Stress Test
Consider pharmacologic stress test under the following circumstances:•Acute thrombophlebitis or deep venous thrombosis•Neuromuscular, musculoskeletal or arthritic condition that precludes treadmill exercise•Patient’s inability or lack of desire to perform the test•Easy fatigability
Consider cardiac catheterization under the following circumstances:•Recent (within 6 weeks) acute myocardial infarction•Angina at rest•Severe symptomatic left ventricular dysfunction•Potentially life-threatening arrhythmias•Acute pericarditis, myocarditis or endocarditis•Severe aortic stenosis•Acute pulmonary infarct or embolus•Acute or serious general illness
Medical therapy and lifestyle modification recommendations (if no contraindications):•B-blocker--titrate to achieve a resting heart rate of 50-60 beats per minute•Calcium channel blocker* and/or nitrates** (if symptoms persist with B-blocker monotherapy)•ACE-I for patients with CHF, LV dysfunction (EF<40), hypertension, or diabetes•Aspirin 75-325 mg qd (or, Clopidogrel 75 mg/d if Aspirin contraindication)•Lipid-lowering therapy (see Hyperlipidemia guideline)•Low-cholesterol diet education•Physical exercise education•Smoking cessation•Nitroglycerin (sublingual or spray)--patient must be instructed in its use.
*Caution with negative inotropic agents IF impaired left ventricular function present (consider dihydropyridines as Ca-channel blockers of choice in compensated CHF)**Long-acting nitrates, with daily nitrate-free interval.
Physician focus for Evaluating and Treating Stable Angina:
• See patients diagnosed with stable angina within two months of initial diagnosis.Indicator: Percentage of adults diagnosed with stable angina who have a follow-up appointmentwith their PCP or Cardiologist within 2 months of initial diagnosis
• Prescribe beta-Blocker therapy for patients with stable angina, unless contraindicated or nottolerated.
Indicator: Percentage of adults with stable angina filling a prescription for a beta-Blocker.

Congestive Heart Failure (CHF)
*For ACE-I and B-blockers, start with very low doses and titrate to target dosage (see page 2) as tolerated**B-blockers should not be started during an acute worsening of clinical status or when patient has fluid overload. FDA-approved B-blockers include Carvedilol (Coreg), Bisoprolol (Zebeta) and Metoprolol succinate (Toprol XL)
Common Symptoms of CHF:•Paroxysmal nocturnal dyspnea or supine cough•Orthopnea•Dyspnea or cough on exertion•Edema in the lower extremities•Decreased exercise tolerance•Unexplained confusion, altered mental status, or fatigue•Abdominal symptoms associated with ascites and/or hepatic engorgementUncommon Symptoms of CHF:•Pulmonary or systemic embolism in the absence of an obvious cause•Unexplained pleural effusions•Abnormal liver enzymes
Symptoms andsigns of heart
failure
Likely diastolic dysfunction, valvular heart disease,
or a non-cardiac etiology (beyond scope of this guideline)
Reversible cause (e.g.,ischemic or valvular
heart disease)?
Assess LV function (Echocardiogram,
Radionuclide Ventriculogram)
Asymptomatic(NYHA Class 1)•ACE-I*•B-blocker*, **
Is ejectionfraction

Consider referral to address cause, then
reconsider pharmacologictherapy
Systolic dysfunction.Determine symptom
class and treat as follows (unless contra-
indications exist)
yes yesno
no
Include comprehensive patient education (see page 2)
Symptomatic(NYHA Class II-IIIa)•ACE-I*•B-blocker*, **•Diuretic (may be prn edema and congestion)
If symptoms persist:•Digoxin
Symptomatic with history of recent rest dyspnea(NYHA Class IIIb)•ACE-I*•B-blocker*, **•Diuretic (dosing may be modified depending uponmagnitude of congestion)•Spironolactone •Digoxin
Symptomatic with rest dyspnea(NYHA Class IV)•ACE-I* •Diuretic (dosing may be modified depending uponmagnitude of congestion)•Spironolactone--monitor potassium (<5.0) and creatinine (<2.5)•Digoxin
•Consider Aspirin (especially if patient has known CAD) •Consider warfarin anticoagulation in patients with left ventricular ejection fraction of 35% or less•Warfarin anticoagulation in patients with heart failure and atrial fibrillation (goal INR= 2.0 to 3.0), unless contraindicated•In symptomatic patients, if ACE-I is not tolerated, consider Hydralazine and Isosorbide Dinitrate combination. Alternatively,may consider Angiotensin II Receptor Blockers (ARBs), although not shown to have comparable decrease in mortality, available
with beta blockers and ACE-I•Avoid drugs that may exacerbate CHF: Class I anti-arrhythmics, NSAIDs, some “first-generation” calcium channel blockers (i.e., diltiazem, nifedipine, verapamil)
Complete history andphysical exam and
clinically appropriate diagnostic tests
Diagnostic tests to consider:•CBC•AST, alkaline phosphatase•Sodium, potassium•Creatinine, BUN•Protein or albumin•Urinalysis•Thyroid function•Magnesium, calcium•Iron/ferritin•Electrocardiogram•Chest radiograph
Cath or image study

yes
CHF (Page 2)
NYHA Class NYHA Symptom DescriptionI Asymptomatic. No limitation of physical activity. Ordinary physical activity does not cause undue
fatigue, palpitation, or dyspnea.II Mildly symptomatic. Slight limitation of physical activity. Comfortable at rest, but ordinary physical
activity results in fatigue, palpitation or dyspnea.III Moderately symptomatic. Marked limitation of physical activity. Comfortable at rest, but less than
ordinary activity causes fatigue, palpitation or dyspnea.IV Symptoms at rest. Unable to carry out any physical activity without discomfort. Symptoms of cardiac
insufficiency at rest. If any physical activity is undertaken, discomfort is increased.
Patient Education•Low-salt diet•Moderation of fluid intake•Alcohol restriction•Self-monitoring with daily weights (especially NYHA Class III-IV)•Symptoms of exacerbation•Smoking cessation (if applicable)•Exercise regimen•Importance of flu and pneumococcal vaccination
ACE-I target dosesCaptopril 150 mg/dEnalapril maleate 20 mg/dRamipril 10 mg/dLisinopril 40 mg/dQuinapril hydrochloride 40 mg/dTandolapril 4 mg/d*Renal function and serum potassium levels should be assessed within 1-2 weeks of initiation and every 2-3 months thereafter.
Physician focus for Evaluating and Treating Congestive Heart Failure (CHF):
• Prescribe ACE-Inhibitors (or nitrates plus hydralazine) for all CHF patients withoutcontraindications.
Indicator: Percentage of adults with diagnosis of CHF treated with ACE-Inhibitors (OR nitratesplus hydralazine)
• Titrate ACE-Inhibitors to target dose, as tolerated, in patients with CHF.Indicator: Percentage of adults with diagnosis of CHF, treated with ACE-Inhibitors, at targetdoses. These target doses are outlined on page 2 of the CHF guideline.

Osteoarthritis of the hipAseptic necrosis of the femoral headSciatic nerve injury due to pressure, stretch or piriformis muscle entrapmentCyclic radiating low back pain— endometriosis on the sciatic nerve/ sacral plexusIntrapelvic masses—benign or malignantPeroneal (fibular) nerve entrapment at the fibular headSacroiliac joint dysfunctionFacet joint syndromeInternal disk disruption
Gordon Waddel’s five “non-organic pain” signs1. Overreaction during the exam2. Simulated testing--pain with axial loading or rotation of the pelvis and shoulders in the same plane3. Distracted testing--test straight leg raise while distracted when sitting.4. Superficial, non-anatomical or variable tenderness. When skin rolling over the back markedly increases the pain5. Non-anatomical motor or sensory disturbances. Positive when sensoryloss does not follow a dermatome or entire leg is numb or without stretch or when there is a “ratchety” giveway on strength testing.
Presence of two or more of these findings correlates with poor surgical outcome, but not rehabilitation outcome. Patient is at risk for becoming chronically disabled. Should not be interpreted as specific for malingering.
Physician focus for Evaluating and Treating Acute Low Back Pain
• Prescribe a conservative treatment plan for patients with Acute Low Back Pain before orderingdiagnostic radiological studies (unless critical exclusionary diagnoses are present). Indicators:

Interpreting Spirometry:
Referral is recommended when:• Life threatening asthma exacerbations• Is not meeting treatement goals, or unresponsive to therapy• Atypical signs and symptoms• Complicating comorbidities (e.g. sinusitis, nasal polyps, vocal cord dysfunction, COPD)• Additional diagnostic testing indicated• Additional patient education/guidance needed• Immunotherapy considered• Patient has severe persistent asthma• Patient requires continuous oral corticosteroid therapy or high-dose inhaled corticosteroids• Patient is under age 3• Confirmation of history that suggests occupational or environmental inhalant or ingested
substance causing asthma.
General Guidelines for Referral to an Asthma Specialist:
Physician focus for managing patients with asthma:
• Prescribe anti-inflammatory medication to all patients with persistent asthma.Indicator: Percentage of patients with persistent asthma with prescriptions for an anti-inflammatory medication.
• Monitor patients for overuse of β-agonist medication and re-evaluate/educate patient.Indicator: Percentage of patients with greater than three MDIs filled at pharmacy in a 3 monthperiod.
• Utilize objective measures (spirometry or peak flow) for accurate assessment of lung function.Indicator: Percentage of patients with asthma with spirometry or peak flow documented in themedical record at the last visit.
• Educate patients, including an asthma action plan.Indicator: Percentage of patients with asthma with an asthma action plan in the medical record.documented in their chart at the last visit.
• Counsel patients diagnosed with asthma regarding smoking cessation.Indicator: Percentage of adults diagnosed with asthma who receive smoking cessation education,as documented in the medical record (or billing charges).

CAGE(AID) Screen
Have you ever:C felt you ought to cut down on your
drinking or drug use?A had people annoy you by criticizing your
drinking or drug use?G felt bad or guilty about your drinking or
drug use?E had a drink or used drugs as an eye
opener first thing in the morning to steady your nerves or get rid of a hangover or to get the day started?
If substance abuse is present or suspected, consider referral for chemical dependency assessment.
Major Depressive Episode--DSM IV CriteriaMust have a total of five symptoms for at least two weeks. One of the symptoms must be depressed mood or loss of interest.
•Depressed mood.
•Markedly diminished interest or pleasure in all or almost all activities.
•Significant (>5% body weight) weight loss or gain or decrease or increase in appetite.
•Insomnia or hypersomnia.
•Psychomotor agitation or retardation.
•Feeling of worthlessness or inappropriate guilt.
•Diminished concentration or indecisiveness.
•Recurrent thoughts of death or suicide.
Treatment(Patient Education Considerations)
Both pharmacologic and non-pharmacologic interventions may be effective depending on the severity of symptoms. For antidepressant medications, compliance with a therapeutic dose is more important than the specific drug selected. The following educational messages may increase adherence:
•Take the medication daily.
•Antidepressants must be taken for two to four weeks for a noticeable effect.
•Continue to take medicine even if feeling better.
•Do not stop taking antidepressant without checking with your provider.
•Contact your provider if you have questions about your medication.
Referral to Psychiatrist
Consider psychiatric consultation for patients with:• History of mania or psychosis• Condition not responding to trials of one or two
medications• Need for combination therapyImmediate psychiatric evaluation is necessary if
patient may harm themselves or others.
Physician focus for management of depression:
• Increase the detection and diagnosis of depression in primary care through application ofspecific criteria.
Indicator: Percentage of adults complaining of depression containing documentation of DSM-IVcriteria at the time of initial diagnosis.
• Increase screening for depression in patients with somatic complaints.Indicator: Percentage of adults complaining of fatigue or sleep disorder who have documentationof screening for depression.
• Follow-up patients with newly diagnosed depression within 6 weeks of initial diagnosis.Indicator: Percentage of adult patients newly diagnosed with depression who have a follow-upappointment within 6 weeks.
