Noncommunicable diseases (NCDs) are long-lasting conditions that are not passed from person to person. They are the leading causes of death in the Philippines, with cardiovascular disease (heart disease and stroke) at the top, followed by cancers, diabetes, and chronic respiratory disease.

The "4 × 4" (WHO) model — four main NCDs share four modifiable risk factors (air pollution is often added as a fifth):

Intermediate (metabolic) risk factors — raised blood pressure, raised blood glucose, abnormal lipids, and overweight or obesity — sit between behavior and disease and are the targets of screening.

Goals of community NCD programs

• Primary prevention: reduce risk factors in the whole population (healthy settings, tobacco and alcohol control, salt and sugar reduction, physical activity).
• Secondary prevention: early detection by screening and risk assessment, with prompt treatment.
• Tertiary prevention: continuous management to prevent complications (stroke, kidney failure, amputation, blindness), rehabilitation, and self-management.
• Ultimate aims: fewer complications and premature deaths and better quality of life.

Key thresholds used in Philippine primary care

• Hypertension: clinic blood pressure ≥ 140/90 mmHg (Philippine guidelines), confirmed on repeated readings.
• Diabetes: fasting plasma glucose ≥ 126 mg/dL (7.0 mmol/L), HbA1c ≥ 6.5%, 2-hour OGTT ≥ 200 mg/dL (11.1 mmol/L), or random glucose ≥ 200 mg/dL (11.1 mmol/L) with symptoms. In community screening, fasting plasma (or capillary) glucose is the usual first test, followed by confirmation.
• Obesity (Asia-Pacific cut-offs used locally): BMI 23–24.9 kg/m² = overweight, ≥ 25 kg/m² = obese; abdominal obesity when waist circumference is ≥ 90 cm (men) or ≥ 80 cm (women).

PhilPEN — Philippine Package of Essential NCD Interventions

• The DOH adapted the WHO Package of Essential NCD Interventions (WHO PEN) for primary care. DOH Administrative Order 2012-0029 institutionalized PhilPEN for the integrated management of hypertension and diabetes in primary health care facilities.
• Target: adults 25 years and older without established cardiovascular disease.
• NCD Risk Assessment Form records: family history, smoking, alcohol, physical activity, diet (fruit and vegetables, salt, fat), weight, height, waist circumference, blood pressure, and — when indicated — blood glucose, urine tests, and lipids.
• Total cardiovascular risk is estimated with WHO/ISH risk charts (age, sex, systolic BP, smoking, diabetes, cholesterol when available). Management intensity follows the risk level: lifestyle counseling for everyone, closer follow-up and drug therapy as risk rises, and referral for high-risk or complicated cases.
• The program links risk assessment with a registry and follow-up of identified clients.

Chronic Care Model / self-management support. Good chronic care needs an informed, activated client and a prepared, proactive team. Self-management support means helping clients gain the knowledge, skills, and confidence to make daily decisions about their illness — goal setting, action plans, problem solving, and follow-up — not only giving information.

Registration and tracking — core elements of a chronic disease registry: systematic enrollment, standardized treatment protocols, regular follow-up with recall of defaulters, record keeping, and referral links. Free medicine is helpful where available but is not a defining element of registration management.

Policy and legal framework (population-level primary prevention)

Community NCD screening day (barangay or workplace)

1. Register participants aged 25 and above; explain the purpose and obtain consent.
2. Fill in the risk assessment form: history, lifestyle, family history, current medicines.
3. Measure weight, height, waist circumference, and blood pressure (seated, rested 5 minutes, correct cuff size, two readings).
4. Check blood glucose when indicated (for example, obesity, family history, symptoms, or high BP), preferably fasting.
5. Estimate cardiovascular risk, counsel every participant, and refer those with high readings or high risk to the physician the same day or within the protocol timeframe.
6. Enter clients in the registry, schedule follow-up, and recall those who miss visits.

Lifestyle counseling (the "brief intervention")

• Tobacco: ask, advise, assess readiness, assist, arrange follow-up (the 5 A's); refer to cessation services.
• Diet: reduce salt (avoid adding salt, patis, and toyo; limit processed and instant foods), sugar-sweetened drinks, and fatty meats; eat more vegetables and fruit.
• Physical activity: at least 150 minutes of moderate activity weekly for adults, spread across the week.
• Alcohol: reduce or avoid; no alcohol for pregnant women or minors.
• Weight: gradual, sustainable loss through tailored diet and activity changes that fit the person's environment, motivation, and preferences — not crash diets.

Hypertension teaching — hypertension is usually symptom-free, so stress taking medicines daily even when feeling well, home or clinic BP monitoring, low-salt diet, and regular follow-up. Teach stroke warning signs (sudden face drooping, arm weakness, speech difficulty — seek care immediately).

Diabetes teaching — medication and meal timing, recognition and treatment of hypoglycemia, daily foot inspection, annual eye and kidney checks, and sick-day rules.

Home visits for clients with NCD complications

• Stroke survivors: fall prevention and home safety are the top teaching priority (clear walkways, grab bars, non-slip surfaces, good lighting, assistive devices), along with swallowing safety and medication adherence.
• Heart failure: daily weights; refer urgently for sudden worsening shortness of breath or breathlessness lying flat (orthopnea), which suggests decompensation or pulmonary edema.
• COPD: smoking cessation, inhaler technique, vaccinations, and pulmonary rehabilitation (exercise training, breathing techniques, education) to reduce breathlessness and improve function and quality of life.

1. Case finder — conduct risk assessment and screening; refer abnormal results.
2. Health educator and counselor — individualized lifestyle counseling; self-management support.
3. Case manager — maintain the registry, schedule follow-up, trace defaulters, monitor BP and glucose control.
4. Coordinator — link barangay health workers, physicians, pharmacies, and referral hospitals; organize support groups (hypertension and diabetes clubs).
5. Advocate — support local ordinances on smoke-free places, healthy school canteens, and active transport.
6. Program manager — plan screening schedules, forecast supplies (BP apparatus, glucose strips, medicines), and evaluate outcomes (percentage screened, controlled BP, complications).

• Autonomy: lifestyle change must be the client's decision; use motivational counseling rather than blame.
• Confidentiality: screening results and registry data are sensitive personal information under the Data Privacy Act (RA 10173); do not post names with results in public places.
• Informed consent for screening tests and for enrollment in the registry.
• Equity: NCDs increasingly affect the poor; sin tax earmarking and UHC aim to make prevention and treatment affordable.
• Tobacco laws: health facilities are smoke-free; nurses model compliance and can report violations to local authorities.

Case 1. A 48-year-old jeepney driver has BP 150/96 mmHg on two readings but feels fine and refuses medicines "because nothing hurts."

Action: Explain that hypertension is usually silent yet damages the heart, brain, and kidneys; refer for confirmation and treatment; counsel on salt, activity, and adherence. Why: lack of symptoms is the main reason for non-adherence.

Case 2. At a barangay screening, a 35-year-old woman with obesity and a family history of diabetes asks which test she should have.

Action: Arrange fasting plasma glucose testing and confirm abnormal results. Why: fasting glucose is the usual first-line community screening test for diabetes.

Case 3. During a home visit, a man with heart failure reports he could not lie flat last night and is more breathless today.

Action: Arrange immediate medical evaluation. Why: new orthopnea and sudden dyspnea suggest acute decompensation.

Case 4. A stroke survivor with right-sided weakness lives with his daughter.

Action: Prioritize fall prevention teaching and home modification. Why: falls cause secondary injury and are a leading preventable complication.

• Believing no symptoms means no disease — hypertension and early diabetes are usually silent.
• Using HbA1c as the only community screening test when fasting glucose is the standard first step (HbA1c is diagnostic and a key monitoring tool).
• Treating free medicine as the defining element of chronic disease registration.
• Giving the same generic diet advice to everyone instead of tailoring it to the person's life and preferences.
• Confusing primary prevention (reducing risk factors) with secondary prevention (screening).
• Assuming vapes are unregulated — RA 11900 restricts them to adults 18 and older.
• Forgetting that sin taxes are both a prevention tool and a source of UHC funding.

• Leading NCD killer: cardiovascular disease; four NCDs share four risk factors (tobacco, alcohol, unhealthy diet, inactivity).
• PhilPEN (DOH AO 2012-0029): integrated hypertension and diabetes management in primary care; risk assessment for adults 25 and older.
• Philippine hypertension threshold: ≥ 140/90 mmHg.
• Diabetes: FPG ≥ 126 mg/dL (7.0 mmol/L), HbA1c ≥ 6.5%; fasting glucose for community screening.
• Registry essentials: enrollment, standardized protocols, follow-up and recall, records, referral.
• Self-management support = knowledge, skills, and confidence for daily decisions.
• RA 9211 tobacco regulation; EO 26 nationwide smoke-free environments; RA 10643 graphic warnings; RA 11900 vapes (age 18).
• Sin taxes (RA 10351, 11346, 11467) fund UHC (RA 11223).
• Stroke home visit priority: fall prevention; heart failure red flag: sudden dyspnea or orthopnea.
• Pulmonary rehabilitation reduces breathlessness and improves quality of life in COPD.
