Evidence-Based Intervention Guidelines

Overview

This reference provides comprehensive guidance on selecting, implementing, and documenting evidence-based interventions across pharmacological, non-pharmacological, and procedural treatment modalities. These guidelines support treatment plan development with current best practices and clinical recommendations.

Evidence Hierarchy

Levels of Evidence

Level I: Highest Quality

• Systematic reviews and meta-analyses of randomized controlled trials (RCTs)
• Large multi-center RCTs

Level II: High Quality

• Individual RCTs
• Systematic reviews of observational studies

Level III: Moderate Quality

• Cohort studies
• Case-control studies
• Well-designed observational studies

Level IV: Lower Quality

• Case series
• Case reports
• Expert opinion

Recommendation Strength:

• Grade A: Strong recommendation, high-quality evidence
• Grade B: Moderate recommendation, moderate-quality evidence
• Grade C: Weak recommendation, low-quality evidence
• Grade D: Recommendation against (evidence of harm or no benefit)

Pharmacological Interventions

Medication Selection Principles

1. Evidence-Based Prescribing

• Use medications with proven efficacy for indication
• Follow clinical practice guidelines
• Consider comparative effectiveness data
• Prefer medications with better safety profiles when equivalent efficacy

2. Patient-Specific Factors

• Comorbidities and contraindications
• Organ function (renal, hepatic)
• Drug allergies and intolerances
• Concurrent medications (drug interactions)
• Age, pregnancy status
• Genetic factors (pharmacogenomics when available)
• Cost and insurance coverage

3. Medication Safety

• Start low, go slow (especially in elderly, multiple comorbidities)
• Titrate to target dose based on response and tolerance
• Monitor for adverse effects
• Avoid potentially inappropriate medications (Beers Criteria for elderly)
• Polypharmacy reduction when possible

Common Medication Classes by Indication

Hypertension

First-Line Agents (per JNC-8, ACC/AHA guidelines):

• ACE Inhibitors (lisinopril, enalapril): Preferred if diabetes, CKD, or heart failure
• ARBs (losartan, valsartan): Alternative to ACE if intolerant
• Calcium Channel Blockers (amlodipine): Particularly effective in elderly, Black patients
• Thiazide Diuretics (chlorthalidone, HCTZ): Cost-effective, good CV outcomes

Dosing Strategy:

• Start single agent at low dose
• Titrate to maximum tolerated dose before adding second agent
• Combination therapy often needed (2-3 agents)
• Monitor BP response, adjust every 2-4 weeks

Type 2 Diabetes Mellitus

First-Line (ADA Standards of Care):

• Metformin: First-line for all patients unless contraindicated (eGFR <30)
  • Start 500-850mg daily or BID, titrate to 2000mg total daily

Second-Line (individualize based on comorbidities):

• SGLT2 Inhibitors (empagliflozin, dapagliflozin): If heart failure or CKD (strong cardio-renal benefits)
• GLP-1 Receptor Agonists (semaglutide, dulaglutide): If ASCVD or high risk, weight loss needed
• DPP-4 Inhibitors (sitagliptin): If low hypoglycemia risk desired
• Sulfonylureas (glipizide): Cost-effective but hypoglycemia risk
• Insulin: If HbA1c very elevated ($>$10%) or symptoms of hyperglycemia

Depression

First-Line SSRIs (APA guidelines):

• Sertraline, escitalopram, fluoxetine, citalopram, paroxetine
• Start low (e.g., sertraline 50mg, escitalopram 10mg)
• Titrate after 2-4 weeks if partial response
• Full trial: 6-8 weeks at therapeutic dose
• Continue 6-12 months after remission (longer if recurrent)

Second-Line:

• SNRIs (venlafaxine, duloxetine): Especially if chronic pain comorbidity
• Bupropion: If sexual dysfunction concern, smoking cessation
• Mirtazapine: If insomnia/appetite stimulation needed

Augmentation (if partial response):

• Second antidepressant from different class
• Atypical antipsychotic (aripiprazole, quetiapine) - FDA-approved augmentation
• Lithium, thyroid hormone (triiodothyronine)

Chronic Pain

Multimodal Analgesia (WHO Pain Ladder, CDC Opioid Guidelines):

Non-Opioid Analgesics:

• Acetaminophen: 3-4g/day divided, safe if liver function normal
• NSAIDs: Ibuprofen, naproxen, meloxicam - short-term or chronic with GI protection
  • Monitor: Renal function, BP, GI bleeding risk

Adjuvant Analgesics for Neuropathic Pain:

• Gabapentin: 300mg titrated to 1800-3600mg/day divided TID
• Pregabalin: 75mg BID titrated to 150-300mg BID (better bioavailability than gabapentin)
• SNRIs (duloxetine): 60mg daily for diabetic neuropathy, chronic MSK pain
• TCAs (amitriptyline, nortriptyline): Low-dose (10-75mg QHS) - second-line due to side effects

Topical Agents:

• Lidocaine patches 5%, diclofenac gel, capsaicin cream
• Local effect, minimal systemic absorption

Opioids (CDC guidelines - use cautiously):

• Only after non-opioid multimodal therapies inadequate
• Lowest effective dose, short-acting preferred initially
• Avoid $>$90 MME/day if possible
• UDS, PDMP monitoring, naloxone co-prescription
• Reassess frequently, taper if not meeting functional goals

Heart Failure with Reduced Ejection Fraction (HFrEF)

Guideline-Directed Medical Therapy (GDMT) - "Foundational Four":

1. ACE Inhibitor or ARB or ARNI

   • ACE: Lisinopril 20-40mg daily, enalapril 10-20mg BID
   • ARNI (Sacubitril/Valsartan): 24/26mg BID → 97/103mg BID (superior to ACE/ARB)
   • Monitor: BP, renal function, potassium

2. Beta-Blocker

   • Carvedilol 3.125-6.25mg BID → 25mg BID (target)
   • Metoprolol succinate 12.5-25mg daily → 200mg daily
   • Bisoprolol 1.25mg → 10mg daily
   • Titrate slowly, monitor HR, BP

3. Mineralocorticoid Receptor Antagonist (MRA)

   • Spironolactone 12.5-25mg daily (up to 50mg)
   • Eplerenone 25mg daily → 50mg daily
   • Monitor: Potassium, renal function (risk hyperkalemia)

4. SGLT2 Inhibitor

   • Dapagliflozin 10mg daily or empagliflozin 10mg daily
   • Reduces HF hospitalizations and mortality
   • Also beneficial for diabetes and CKD

Additional Therapies:

• Loop diuretic (furosemide) for volume management (not mortality benefit)
• Hydralazine-isosorbide dinitrate (if African American or intolerant to ACE/ARB)
• Ivabradine (if EF $\leq$35%, HR $>$70 on max beta-blocker)
• Digoxin (symptomatic benefit, reduce hospitalizations)

Medication Documentation Best Practices

Include in Treatment Plan:

• Generic name (brand name optional)
• Dose, route, frequency
• Indication/rationale
• Titration plan if applicable
• Expected timeline for benefit
• Key side effects to monitor
• Drug interactions
• When to adjust or discontinue

Example: "Lisinopril 10mg PO daily - ACE inhibitor for hypertension and renal protection in diabetes. Titrate to 20mg in 2-4 weeks if BP not at goal and tolerating (monitor for cough, hyperkalemia). Target BP <130/80."

Non-Pharmacological Interventions

Lifestyle Modifications

Diet and Nutrition

Mediterranean Diet (Evidence: multiple RCTs, PREDIMED trial):

• Indications: Cardiovascular disease prevention, diabetes management
• Components:
  • High intake: Fruits, vegetables, whole grains, legumes, nuts, olive oil
  • Moderate: Fish, poultry
  • Low: Red meat, sweets
• Evidence: Reduces cardiovascular events by 30%, improves glucose control
• Implementation: Dietitian referral for medical nutrition therapy

DASH Diet (Dietary Approaches to Stop Hypertension):

• Indication: Hypertension
• Components: High fruits/vegetables, low-fat dairy, reduced sodium (<2300mg, ideally <1500mg)
• Evidence: Reduces SBP by 8-14 mmHg
• Implementation: DASH eating plan education, sodium tracking

Carbohydrate Counting (for Diabetes):

• Consistent carbohydrate intake: 45-60g per meal
• Enables insulin dosing adjustment
• Prevents glycemic variability
• Dietitian teaches carb counting skills

Weight Management:

• Caloric deficit: 500-750 kcal/day for 1-2 lb/week weight loss
• Behavior change strategies: Self-monitoring, stimulus control, goal-setting
• Structured programs (Weight Watchers, MOVE!, etc.) more effective than self-directed
• Pharmacotherapy (GLP-1 agonists, orlistat) or bariatric surgery for BMI $\geq$30-35 with comorbidities

Physical Activity and Exercise

Aerobic Exercise:

• Recommendation: 150 min/week moderate intensity OR 75 min/week vigorous
• Moderate: Brisk walking, cycling, swimming - can talk but not sing
• Vigorous: Running, fast cycling - can say few words before pause
• Benefits: Cardiovascular health, glucose control, weight management, mood
• Implementation: Start with 10 min sessions, gradually increase

Resistance Training:

• Recommendation: 2-3 sessions/week, all major muscle groups
• Benefits: Muscle strength, bone density, metabolic rate, glucose control
• Implementation: Bodyweight exercises, resistance bands, free weights, machines

Balance and Flexibility:

• Important for fall prevention in elderly
• Yoga, tai chi
• Stretching routines

Exercise Prescription:

• FITT principle: Frequency, Intensity, Time, Type
• Individualize based on fitness level, comorbidities, goals
• Cardiac clearance if indicated (using ACSM or ACC/AHA guidelines)

Example: "Aerobic exercise: Walk 30 minutes, 5 days/week at moderate intensity (target HR 50-70% max). Resistance training: Upper and lower body exercises 2x/week, 2 sets of 10-12 reps."

Smoking Cessation

Evidence: Strongest intervention for COPD, cardiovascular disease, cancer prevention

5 A's Approach:

1. Ask: Screen all patients for tobacco use
2. Advise: Urge all tobacco users to quit
3. Assess: Willingness to make quit attempt
4. Assist: Aid in quitting (counseling + medication)
5. Arrange: Follow-up contact

Pharmacotherapy (doubles quit rates):

• Nicotine Replacement: Patch, gum, lozenge - OTC, safe
• Varenicline: Most effective (Chantix), start 1 week before quit date
• Bupropion: Alternative, also treats depression
• Combination: NRT + varenicline/bupropion more effective

Counseling:

• Quitline: 1-800-QUIT-NOW
• Individual or group counseling
• Cognitive-behavioral techniques

Implementation: Set quit date within 30 days, prescribe pharmacotherapy + counseling referral, follow up within 1 week of quit date.

Sleep Hygiene

Indications: Insomnia, poor sleep quality

Implementation: 12-16 weekly 50-min sessions with trained therapist, homework between sessions

Variants:

• CBT-I (insomnia): Sleep restriction, stimulus control, cognitive therapy for sleep
• CBT-CP (chronic pain): Pain education, activity pacing, cognitive restructuring of pain catastrophizing

Motivational Interviewing (MI)

Indication: Ambivalence about behavior change (diet, exercise, substance use, medication adherence)

Principles:

• Express empathy
• Develop discrepancy (between current behavior and goals/values)
• Roll with resistance (don't argue)
• Support self-efficacy

Techniques:

• Open-ended questions

Procedure: Trial lead placement (5-7 days), if successful → permanent implant

Technologies: Traditional, high-frequency, burst stimulation, dorsal root ganglion (DRG)

Surgical Interventions

When to Refer for Surgery:

• Failed conservative management (adequate trial - typically 6-12 weeks minimum)
• Progressive neurologic deficit
• Cauda equina syndrome (emergency)
• Severe functional limitation affecting quality of life
• Structural pathology amenable to surgical correction
• Patient preference after risks/benefits discussion

Shared Decision-Making: Discuss operative vs. non-operative management, risks, benefits, expected outcomes, recovery

5. Individualized: Adjust for patient factors (comorbidities, preferences, resources)

Documentation Template

For each intervention, document:

• Intervention: Specific name/type
• Indication: Why this intervention for this patient
• Evidence: Guideline-based, RCT data supporting use
• Dose/Frequency/Duration: Specific parameters
• Expected Benefit: What should improve, by how much, when
