Occupational chronic bronchitis
Apr
Occupational chronic bronchitis is a term commonly used in the previous decade to refer to cases of chronic inflammation of the respiratory tract. However, after the term chronic obstructive pulmonary disease (COPD) appeared, the term chronic bronchitis has been used less frequently, and is now limited to cases where all causes of prolonged cough—such as COPD, bronchial asthma, bronchiectasis, interstitial pneumonia, gastroesophageal reflux, etc.—have been excluded.
1. What is occupational chronic bronchitis?
Lesions in chronic bronchitis mainly localize in the airway mucosa. The disease often begins with episodes of respiratory infections that cause inflammation, edema, increased mucus secretion, and airway narrowing. Without proper treatment, or when respiratory infections recur frequently, the disease progresses into chronic bronchitis.
This disease often occurs in individuals working in environments with smoke, dust, or toxic substances who frequently inhale dust particles and harmful chemicals, leading to chronic bronchitis. It may cause symptoms such as dry cough, shortness of breath, chest pain, and breathing difficulty during physical activity.
2. Occupations at risk of chronic bronchitis
Occupations at risk of occupational chronic bronchitis include:
- Workers in metal, wood, leather, tobacco, cement, paper pulp, and chemical manufacturing and processing industries.
- Agricultural workers, especially those working in livestock and poultry farms.
- Construction workers, particularly those exposed to hazardous substances such as construction dust, asbestos, and chemical agents.
- Occupations related to shipbuilding, ship repair, automobile assembly, and other heavy industries.
- Occupations involving drilling, grinding, cutting, welding, and sandblasting.
These occupations expose workers to harmful agents and fine dust, which can cause occupational chronic bronchitis.
Occupational chronic bronchitis risk assessment tool is an online application designed to evaluate the risk level of workers developing chronic bronchitis (COPD) related to their working environment. This tool uses a series of multiple-choice questions to assess factors such as exposure to smoke, dust, chemicals, and working conditions that may damage the respiratory tract.
With a user-friendly and intuitive approach, the tool provides a composite score that helps users understand their occupational COPD risk level. Results are categorized into various risk levels, from very low to very high, helping workers and healthcare professionals make informed decisions and take preventive measures when needed. The tool also contributes to raising awareness and promoting occupational safety education in the workforce community.
3. Mechanisms and causes of chronic bronchitis
Chronic bronchitis is a chronic lung disease characterized by prolonged bronchial inflammation, tissue damage, and airflow limitation. Causes include:
- Smoking: This is the leading cause of chronic bronchitis, as tobacco smoke contains hundreds of toxic chemical compounds that damage lung and bronchial tissues.
- Exposure to fine dust and small particles in the workplace: Industries such as construction, shipbuilding, metal polishing, mechanical engineering, chemical industries, and abrasive manufacturing pose high risks.
- Exposure to other harmful substances: Auto exhaust, chemical fumes, urban pollution, and smog also contribute.
- Genetic factors: Some individuals may develop chronic bronchitis due to hereditary factors.
The mechanism is primarily prolonged bronchial inflammation, which leads to tissue damage, lung function reduction, and airflow obstruction. Common symptoms include shortness of breath, dry cough, chest pain, and exertional breathing difficulty. Treatment focuses on relieving symptoms, improving lung function, and preventing complications.
4. Symptoms of chronic bronchitis
A person may be suspected of chronic bronchitis when experiencing the following clinical symptoms:
- Persistent cough: often mild or episodic; symptoms worsen after respiratory infections or when exposed to cold weather, smoke, or dust.
- Persistent sputum production: sputum is usually white; in cases of bacterial infection, it may turn yellow or green. Fever is uncommon unless there is flu or severe bacterial exacerbation.
- Shortness of breath: less common in chronic bronchitis. If present, COPD, asthma, or heart failure should be investigated.
- Fatigue: patients often complain of tiredness, though weight loss is uncommon.
These symptoms often recur frequently, and each treatment episode tends to last long. Physicians may not detect significant abnormal signs during physical examinations of chronic bronchitis patients.
5. Harms of occupational chronic bronchitis
Occupational chronic bronchitis can cause multiple health and lifestyle impacts:
- Reduced work capacity: The disease may limit daily activities and lower quality of life.
- Increased risk of other lung diseases: Such as flu, pneumonia, and acute bronchitis.
- Declined lung function: Causes breathing difficulty and reduced physical performance.
- Higher risk of lung cancer: Persistent, untreated bronchitis increases susceptibility.
- Psychological effects: Patients may feel isolated, stressed, or depressed.
- Increased healthcare costs: Treatment and long-term care may cause financial burden.
Thus, prevention is crucial through using masks, personal protective equipment, and minimizing exposure to harmful agents. Patients should seek treatment and pulmonary rehabilitation to reduce long-term harm.
6. Complications of chronic bronchitis
Complications of chronic bronchitis are grouped into two categories: lung-related and systemic complications.
+ Lung-related:
- Pneumonia: Patients have an increased risk of lung infections.
- Pulmonary hypertension: Occurs when the lungs cannot adequately exchange oxygen and carbon dioxide.
- Asthma: Chronic bronchitis may lead to airway hyperresponsiveness.
+ Systemic complications:
- Heart failure: Prolonged bronchitis can increase cardiac strain.
- Liver dysfunction: Long-term inflammation may impair metabolism and detoxification.
- Kidney stress and dysfunction: Chronic inflammation may strain the kidneys.
- Loss of bronchial mobility: Airway structures lose proper function, causing severe breathing difficulty.
Early detection and treatment are crucial to reduce these risks.
7. Protective equipment to prevent chronic bronchitis
Protective gear plays a vital role in safeguarding workers exposed to dusty or toxic environments:
- Respirators: Essential for preventing inhalation of smoke, dust, and toxic chemicals. The type of respirator should match workplace hazards and be worn correctly.
- Safety goggles: Protect the eyes from debris, dust, fumes, and harmful agents.
- Protective clothing: Includes jackets, pants, and safety shoes designed to prevent exposure to hazardous substances.
- Protective gloves: Protect hands from chemical hazards and contaminants.
- Oxygen tanks: In some hazardous environments, workers may require oxygen tanks to protect their lungs from contaminants.
8. Compensation for workers with occupational chronic bronchitis
According to Vietnam’s Social Insurance Law, workers with occupational diseases, including chronic bronchitis caused by hazardous work environments, are entitled to compensation benefits.
Workers may receive:
- Occupational disease allowance: Covers medical examination, treatment, medication, and related costs.
- Rehabilitation allowance: For long-term treatment to restore health and working ability.
- Vocational transition allowance: If the disease prevents the worker from continuing their previous job.
- Maternity allowance: For women whose chronic bronchitis affects pregnancy or postpartum health.
9. Treatment for chronic bronchitis
Avoid risk factors that may trigger exacerbations:
- Avoid smoking, second-hand smoke, kitchen smoke, and dusty environments.
- Avoid cold and humidity; wear scarves and masks when going outdoors.
- Avoid indoor drafts.
- Get annual influenza vaccination (optimal in September).
- Use alternative biological immunostimulants to prevent respiratory infections.
10. Prevention of occupational chronic bronchitis
To prevent occupational chronic bronchitis, workers should follow these measures:
- Wear protective gear such as masks, goggles, gloves, respirators, chemical-resistant clothing, and safety shoes.
- Use vacuum or extraction systems to reduce airborne toxins.
- Limit exposure to dust, fumes, and chemicals.
- Maintain a healthy diet, proper rest, and regular exercise.
- Receive regular health checkups to detect early issues.
- Conduct occupational environment monitoring and periodic reporting.
11. Responsibilities of businesses in preventing chronic bronchitis
