Recommended empirical antibiotic therapy according to community acquired pneumonia degree of severity. Chart based on BTS.2 4 guidelines. What is the most common form of aspiration pneumonia? Patients who had not been clinically diagnosed with pneumonia but had radiological pneumonia (n-99) had lower symptoms and less severe individual symptoms, such as fever, cracking and signs of systemic inflammatory reaction syndrome, compared to patients with both an empirical clinical diagnosis and a radiological diagnosis of pulmonary inflammation (n-41) (Table 4). It is not surprising that many believe that breast radiology, which is a relatively inexpensive test, plays a fundamental and important role in the diagnosis of pneumonia, as well as clinical evaluation and sometimes appropriate microbiological tests . Its main objective is to diagnose or exclude pneumonia, but it will also show the extent of pneumonia, the presence or absence of associated comorbid diseases or complications that can all serve as prognostic indicators, and it can also be used for subsequent follow-ups to verify resolution . Breast X-rays are much less useful in suggesting the probable microbial etiology of CAP, although specific patterns can sometimes be seen and particularly useful for immunosuppressed people [36-38]. Certainly, in hospitalized patients, there is evidence that early performance of breast x-rays is associated with clinical benefits, including significantly shorter hospital stays and post-radiology antibiotic use . Assessing the severity of pneumonia depends on the physician`s experience, which often indicates underestimating the severity of the disease . No predictive factor is sufficiently sensitive and specific to predict the development of each patient.
For example, the medical literature has described several prognostic clues that would help the physician identify patients with Community-acquired pneumonia with a low or high risk of complications and/or death during evolution (Table 7) [76,79-82]. None of the predictive models developed allowed patients to be categorized into clearly defined risk categories. The development and dissemination of clinical guidelines that examine the severity of pneumonia based on objective criteria have reduced hospitalizations of low-risk patients and significantly reduced the cost of medical resources without affecting patient development and prognosis [16,17,35,88,89].
