Document Overview
Title: Evidence-Informed Guidance for the Implementation of HPV-Based Cervical Cancer Screening Programmes
Publisher: World Health Organization (WHO), 2026
ISBN: 978-92-4-012417-2 (electronic) / 978-92-4-012418-9 (print)
What This Document Is
This is a 72-page WHO guidance document (not a clinical guideline, but an implementation guide) designed to help countries translate existing WHO screening recommendations into real-world practice. It was developed collaboratively by WHO's Departments of Noncommunicable Diseases and Sexual/Reproductive Health, with input from global experts, ministries of health, NGOs, and multi-country implementation initiatives.
Background & Why It Was Created
Cervical cancer is the 4th most common cancer in women globally, with over 660,000 new cases and ~350,000 deaths in 2022 - 94% of those deaths in low- and middle-income countries (LMICs). Without action, deaths are projected to reach ~514,000 by 2045.
In 2020, WHO launched the Global Strategy to Eliminate Cervical Cancer, with three 2030 targets (the "90-70-90" targets):
- 90% of girls vaccinated with HPV vaccine by age 15
- 70% of women screened with a high-performance test by ages 35 and 45
- 90% of women with cervical disease receiving treatment
Despite these goals, global HPV-based screening coverage was only 7% in 2022 - highlighting a massive gap between policy and reality.
Key Recommendation: Transition to HPV DNA Testing
WHO's 2021 updated guideline (and the 2026 genotyping addendum) recommends transitioning from:
- Visual inspection with acetic acid (VIA), or
- Cytology (Pap smear)
...to HPV DNA/mRNA detection as the primary screening test for both the general population and women living with HIV (WLHIV).
Screening schedules differ by population:
| Population | Screening Start Age | Frequency |
|---|---|---|
| General women | Age 30 (priority 30-49) | Every 5-10 years (DNA) / 5 years (mRNA) |
| WLHIV | Age 25 (priority 25-49) | Every 3-5 years |
Special notes on WLHIV: They face a 2x higher risk of HPV acquisition, 2x lower clearance, and a 6x higher risk of cervical cancer. WHO recommends HPV testing with triage (not without) for this group, and repeat testing at 12 months (vs. 24 months for general population) after a negative triage.
Theoretical Framework
The document uses a multilevel implementation framework built from three established models:
- Cancer Care Continuum framework - the inner triad of health system, provider, and patient
- Proctor's Implementation Outcomes framework - adoption, uptake, retention, sustainability/scale-up
- CICI (Context and Implementation of Complex Interventions) framework - outer contextual conditions (political, epidemiological, geographic, socioeconomic, sociocultural, ethical)
The 48 Implementation Strategies
The document identifies 48 unique strategies across three target levels:
Health System Level (27 strategies)
Strategies include: establishing national mandates, aligning guidelines with WHO, generating local evidence via pilots, multisectoral partnerships, public-private partnerships, external funding, phased implementation, training and technical assistance, integrating cervical screening with other services (HIV, maternal health, family planning), health information systems, cost-effectiveness analyses, and point-of-care vs. centralized testing.
Provider/Facility Level (9 strategies)
Training providers, task-shifting (e.g., nurses performing ablation instead of doctors), creating care delivery teams, performance audits, provider incentives, reminders to offer screening.
Women-Targeted Level (12 strategies)
CHW-delivered education, HPV self-sampling kits, social media/mass media campaigns, community leader engagement, peer-to-peer networks, patient navigation, invitation/reminder systems, community outreach.
8 Key Strategies Highlighted in Detail
The document gives in-depth descriptions and real-world case studies for these eight strategies:
| # | Strategy | Outcome Targeted |
|---|---|---|
| 8 | External facilitators/consultants | Adoption, scale-up |
| 11 | Training and technical assistance | Adoption, scale-up |
| 25 | Improving treatment capacity | Retention, scale-up |
| 30 | Engaging in-country experts & professional orgs | Adoption, scale-up |
| 42 | CHW-delivered education & awareness | Uptake |
| 46 | HPV self-sampling kits | Uptake |
| 18+47 | Systematic results delivery + patient navigation | Retention |
Notable country case studies included:
- Côte d'Ivoire - Partnership with Expertise France/Unitaid (SUCCESS project) expanded HPV screening to 200 health centres by 2025
- Nigeria - CHAI-supported 5-day training-of-trainers programme for physicians and nurses
- Viet Nam - Decentralized HPV screening to community health stations using existing midwife workforce
- Slovenia - Stepwise engagement with professional societies led to adoption of primary HPV screening nationally in 2026
- India - CHWs carrying HPV self-sampling kits during home visits; ~90% of samples collected at home
- Peru - 930,000 women screened by December 2025; 70% chose HPV self-sampling; scaled to 21 regions
- Malaysia - ROSE project combining HPV self-sampling, digital registry, and mobile navigation platform
Contextual Conditions That Influence Implementation
The document maps 14 contextual conditions under 6 domains that programmes must assess:
- Political - National commitment, WHO alignment, coalition-building, trust, political will
- Epidemiological - Local burden data, data infrastructure for tracking
- Geographic - Distance/access to services, complexity of care pathways
- Socioeconomic - Workforce capacity, task-sharing ability
- Sociocultural - Trusted information access, gender-sensitive care, cues to preventive action
- Ethical - Equitable access, timely treatment, managing loss to follow-up
Planning & Documentation Tool
Section 6 provides a practical toolkit for programme managers:
- Indicator tables for each implementation outcome (adoption, uptake, retention, sustainability) at health system, facility, and patient levels
- 4 strategy boxes (Boxes 1-4) as checklists - programs can mark each strategy as: Not using / Planning to implement / Implementing / Planning to scale
Most adoption/sustainability indicators are Yes/No measures. Uptake and retention indicators require quantitative milestones (e.g., 70% screening participation, 90% treatment completion).
Key Conclusions
- No single universal strategy works - selection must be context-specific and participatory
- Multi-component approaches are most effective - especially provider training + task-shifting, which influenced all 4 implementation outcomes
- HPV testing amplifies strong implementation, but does not replace it - infrastructure, community engagement, and workflows must be addressed regardless of test type
- Evidence gaps remain - many strategies are practice-based; comparative effectiveness data are limited
- Documentation is a call to action - countries are urged to prospectively document strategy use using the provided tool, to build an evidence base for future programmes
This document functions as a practical, systems-level field guide for health ministries, programme managers, NGOs, and implementation researchers working on cervical cancer elimination globally.

Tobacco Cessation - A Comprehensive Clinical Overview
Sources: Fuster & Hurst's The Heart (15th ed.); Goldman-Cecil Medicine; Lee's Essential Otolaryngology; Fishman's Pulmonary Diseases
Why Cessation Matters - The Health Benefits
Quitting smoking produces rapid, substantial benefits:
- Within hours: Heart rate drops, blood CO levels fall
- Within days: Platelet activation decreases
- After 1 year: Half of excess coronary heart disease (CHD) risk is eliminated
- After 5-15 years: Excess stroke risk nearly eliminated
- Quitting before age 40 eliminates almost all risk of premature death from smoking-related disease; even quitting after age 65 still adds years of life
In established CVD:
- 36% reduction in all-cause mortality (systematic review of 20 studies)
- After MI: mortality reduced by 15-61%; risk of repeat events decreases to nonsmoker level within 3 years of cessation
- In COPD: slower lung function decline, fewer exacerbations, lower mortality
- In lung cancer: reduced risk of recurrence and other cancers
Step 1: Assess Nicotine Dependence
Before selecting treatment, assess dependence level. Key indicators:
- Time to first cigarette after waking (≤30 min = high dependence) - determines NRT dose (4 mg vs 2 mg gum/lozenge)
- Number of cigarettes per day (≥25/day = higher dose NRT)
- Previous quit attempts and which treatments helped or failed
The "5 A's" framework is standard in clinical practice: Ask, Advise, Assess, Assist, Arrange.
Step 2: Pharmacotherapy (First-Line)
The FDA has approved 7 medications for smoking cessation. There are 3 main classes:
A. Nicotine Replacement Therapy (NRT)
NRT works by alleviating withdrawal symptoms, allowing the patient to focus on behavioral/conditioning factors. It increases quit rates 1.5 to 2.5-fold vs. placebo. Safe even in patients with established CVD - meta-analyses show no increase in major cardiovascular events.
| Product | Route | Availability | Key Notes |
|---|---|---|---|
| Transdermal patch | Skin | OTC | 21 mg (≥10 cigs/day), 14 mg (<10 cigs/day). Once daily - best compliance. 24-hr or 16-hr patches |
| Nicotine gum | Buccal | OTC | 4 mg (1st cig ≤30 min of waking), 2 mg (>30 min). Chew-and-park technique. No acidic drinks before/during use |
| Nicotine lozenge | Buccal | OTC | 4 mg or 2 mg; dissolves in mouth; preferred in those with dental work. Greater nicotine absorption than gum |
| Nicotine inhaler | Oral/buccal | Rx only | Mimics hand-to-mouth ritual; puff into mouth (not into lungs); max 16 cartridges/day |
| Nicotine nasal spray | Nasal | Rx only | Fastest onset of all NRT; 0.5 mg/spray, one spray each nostril; highest abuse potential |
Combination NRT (patch + rapid-acting form) is now standard of care and is more effective than any single product (RR 1.25 over monotherapy). This is one of the two first-line choices per the ACC Expert Consensus for smokers with CVD.
Duration: At least 8-12 weeks; extended treatment (up to 24 weeks) shows higher long-term abstinence. Starting the patch before the quit date may improve success.
B. Varenicline (Chantix / Champix)
- Mechanism: Partial agonist at α4β2 central nicotinic acetylcholine receptors - reduces craving and blocks nicotine's rewarding effects
- Efficacy: Highest single-agent quit rate; superior to bupropion and NRT monotherapy in head-to-head trials
- The ACC lists varenicline as the other first-line choice for CVD patients alongside combination NRT
- Dose: Start 1 week before quit date; 0.5 mg/day × 3 days → 0.5 mg twice daily × 4 days → 1 mg twice daily × 12 weeks (can extend to 24 weeks)
- Side effects: Nausea (most common, take with food/water), abnormal dreams, insomnia
- Cardiovascular safety: Reassuringly confirmed in large RCTs including EAGLES trial
- Psychiatric warning: Previously had black-box warning for neuropsychiatric events; the EAGLES trial largely allayed these concerns, but monitor patients with pre-existing psychiatric illness
C. Bupropion SR (Zyban / Wellbutrin SR)
- Mechanism: Not fully established; likely inhibits reuptake of dopamine and norepinephrine in the CNS; also a nicotinic receptor antagonist
- Efficacy: Approximately doubles quit rates vs. placebo; comparable to NRT monotherapy
- Dose: 150 mg/day × 3 days → 150 mg twice daily; start 1-2 weeks before quit date; use for 7-12 weeks (can extend to 6 months)
- Side effects: Insomnia, dry mouth, headache, increased blood pressure
- Contraindications: Seizure disorder, eating disorders (bulimia/anorexia), concurrent MAOIs, and caution in heart failure (increases BP; cardiovascular safety less established than NRT or varenicline)
- Combining bupropion + NRT patch does not appear superior to either agent alone
D. Combination Strategies
- Combination NRT (preferred over monotherapy) - standard of care
- Varenicline alone - generally preferred over bupropion
- Bupropion + NRT patch - not significantly better than bupropion alone
- Adding behavioral support to any pharmacotherapy is strongly recommended - nearly all efficacy trials included behavioral support
Step 3: Behavioral Treatments
Pharmacotherapy alone is less effective than pharmacotherapy + behavioral support. Behavioral approaches include:
| Treatment | Evidence | Details |
|---|---|---|
| Cognitive-Behavioral Therapy (CBT) | Strong | Identifies high-risk situations (triggers); teaches coping strategies (behavioral substitution, cognitive reframing). Works in individual or group format |
| Motivational Interviewing | Moderate | Patient-centered; explores and resolves ambivalence about quitting; increases intention to quit |
| Brief physician advice | Moderate | Even a brief "you should quit" from a physician increases cessation rates over no advice |
| Telephone quitlines (e.g., 1-800-QUIT-NOW in USA) | Moderate | Trained tobacco coaches; scheduled calls before and after quit date; many offer free NRT samples |
| Text messaging / web-based programs | Moderate | Online interventions yield quit rates similar to in-person; highly scalable |
| Relapse prevention | Moderate | Recognizing high-risk situations, managing lapses; especially important given that most smokers relapse within 6 months |
Acupuncture and hypnotherapy have NOT shown consistent benefit and are not recommended as primary treatments.
Step 4: Special Clinical Populations
- CVD patients: All FDA-approved cessation medications are safe to use. NRT: no increase in major CV events. Varenicline: confirmed safe. Bupropion: caution in heart failure (BP elevation)
- COPD patients: Cessation is the single most effective intervention to slow lung function decline; all pharmacotherapies applicable
- WLHIV / immunocompromised: Standard cessation approaches apply; integrate into HIV care visits
- Pregnancy: NRT is preferred over continued smoking; bupropion and varenicline are generally avoided (limited safety data)
- Smokeless tobacco / waterpipe users: Varenicline and nicotine lozenges have evidence for smokeless tobacco; bupropion and behavioral intervention for waterpipe users (evidence is more limited)
Step 5: Clinical Practice Framework (Outpatient & Inpatient)
- Outpatient: Integrate cessation counseling into every cardiovascular or primary care encounter. Even 3 minutes of counseling can increase quit rates
- Inpatient: Hospital admission is a "teachable moment." All admitted smokers should receive cessation counseling and a prescription for pharmacotherapy on discharge. Inpatient-initiated treatment significantly increases long-term cessation rates
- Secondary prevention: After MI, stroke, or revascularization, smoking cessation is as effective as any other cardiac medication - it should be treated as an essential part of the care plan, not optional
Summary: Choosing a Treatment
1st line (choose one or combine):
→ Combination NRT (patch + gum/lozenge/spray/inhaler)
→ Varenicline
2nd line:
→ Bupropion SR
→ NRT monotherapy
Always add behavioral support to any pharmacotherapy.
