Acute bronchitis, also known as a chest cold, is short-term bronchitis – inflammation of the bronchi (large and medium-sized airways) of the lungs. However, most GPs are worried that they might miss a case of acute community-acquired pneumonia (CAP), which still has relatively high mortality, especially among the elderly.6 The criterion standard for diagnosing CAP is the presence of consolidation on the chest radiograph, but GPs cannot be ordering chest x-ray scans for every patient with acute cough. You recommend that Mr Smith use an over-the-counter medication (dextromethorphan, with or without an antihistamine) at night for the next 7 to 10 days. Do not smoke and stay away from others who smoke. Also, people with underlying and chronic diseases or compromised immune systems should be considered and treated differently; primary care clinicians will have no difficulty recognizing such patients. This type of cough, also described as acute bronchitis, is the fifth most common new presentation to FPs in Australia2 and the United States.3 Figures from the United Kingdom suggest there are about 50 cases per 1000 people each year,4 and acute cough leads to 10 ambulatory visits per 1000 visits each year in the United States.5 Evidence from such general practice reports and the US and UK morbidity surveys shows that the overwhelming majority of acute coughs are infectious in origin. A chest X-ray can help determine if you have pneumonia or another condition that may explain your cough. Some doctors have questioned whether bronchitis is a clear diagnostic entity; maybe it is just a cold on the chest. The first step in the treatment of acute cough is to determine if the cause of the cough is one of these serious conditions or an acute upper respiratory infection (i.e., common cold), lower respiratory tract infection, or an exacerbation of a preexisting condition (e.g., asthma, bronchiectasis, chronic obstructive pulmonary disease [COPD], or upper airway cough syndrome). Acute cough is one of the most common complaints prompting patient visits to healthcare professionals. The history is also important for discovering if the patient is from an area where diseases that can cause cough (e.g., tuberculosis) are prevalent; has systemic signs of disease (e.g., fever, sweating, weight loss); or has a history of cancer, tuberculosis, or acquired immune deficiency syndrome.

The illness came on slowly, over a day or so. Any patient who responds only partially or not at all to the above therapies should be empirically treated for GERD. 26 Up to that time, and unless there are signs of super-infection or other complications such as painful pleural inflammation, cough seems to be best managed with simple breathing control exercises 28 (see box 2) and medication where indicated (such as proton pump inhibitors if reflux is suspected). The American College of Chest Physicians’ evidence-based clinical practice guidelines1 recommend that patients with acute cough be divided into children (younger than 15 years of age) and adults (15 years of age or older). Smoking cessation is almost always successful in eliminating cough within four weeks. The most common cause of an acute or subacute cough is a viral respiratory tract infection. Half of them concluded that there was no benefit from taking antibiotics; the other half, including a Cochrane review, concluded that antibiotics can have some modest treatment effects compared with placebo.15 The use of antibiotics decreases the time feeling ill with cough and sputum production by about half a day, and reduces time lost from work by about a third of a day. The majority of patients will respond to treatment with inhaled corticosteroids and beta agonists after one week of therapy; it may take up to eight weeks for complete cough resolution. Some patients will respond in as little as two weeks, whereas others may not respond for several months. Cough should resolve within four weeks of therapy. It is also important to determine if the patient is a current smoker. If the cough is due to the common cold, a first-generation antihistamine plus a decongestant should be prescribed.

If the patient has complete or partial resolution of cough after one to two weeks of antihistamine/decongestant therapy, then it is assumed that upper airway cough syndrome was the cause and therapy should be continued.

The patient's description of the character or timing of cough is of limited diagnostic value.

Cough caused by an ACE inhibitor usually will stop within two weeks of ceasing the medication. The cough commonly lasts 7 to 10 days, but can last up to 1 month in 25% of patients.11 When the clinical course of control-group patients in trials of antibiotic treatment of acute bronchitis was studied, it was found that 85% to 90% of patients improved spontaneously, just as quickly as if they had not taken antibiotics.12. The condition is like a “cold on the chest” and it will get better by itself; there is no need for antibiotic treatment. Similarly, apart from a previous history of asthma and a currently runny nose, few symptoms or signs have much of a negative likelihood ratio. Similarly, when the history is suggestive of acute bronchitis and there are no alarm signs in the chest, there is no need for sputum analysis, viral culture, or serologic analysis.

It should take about 2 weeks to get better. If the cough is severe, consider prescribing 30 to 40 mg of prednisone per day for a brief period. When other treatments fail, codeine or dextromethorphan (Delsym) should be considered. Non-life-threatening acute cough (URI, acute bronchitis): Nonpharmacological treatment . The doctor will know whether the patient is immunosuppressed or suffers from asthma or dementia. Ongoing allergen or irritant exposure, lingering effects of an infection, pneumonia, and acute exacerbation of chronic bronchitis should also be considered. Because of the high success rates of therapies directed at specific underlying causes, nonspecific therapy for cough has only a limited role (3, 18). PubMed was relied on to pick up any Cochrane systematic reviews for chronic cough. Acute bronchitis often starts because of another illness, such as a cold or the flu. question for acute, subacute, and chronic cough.

Table 1 shows positive and negative likelihood ratios for pneumonia of various respiratory symptoms and physical signs.10 Note that, apart from egophony, neither symptoms nor signs have high positive likelihood ratios for pneumonia; in a low-prevalence primary care situation, the positive likelihood ratio has to be very high to significantly increase the chances of pneumonia being present. During the past 5 years, you have seen him 3 times. Chest X-ray. Aim: The authors set out to develop a new prediction rule for poor outcome (re-consultation with new or worsened symptoms, or hospital admission) in adults presenting to primary care with acute cough.
