“…High-resolution computed tomography (HRCT) has been shown to detect more infiltrates than CXR in cases of CAP [87][88][89]. It has been suggested to be useful for early diagnosis and treatment of patients with a clinical diagnosis in hospital care [90]. However, the relevance of the findings on HRCT in primary care is unclear, because an infiltrate on HRCT but not on CXR does not necessarily indicate a bacterial infection requiring antibiotic treatment and thus risks overdiagnosis.…”

It is important to identify patients with pneumonia because it is potentially a serious disease, often of bacterial origin, that should be treated with antibiotics. It is equally important to identify those with acute bronchitis, a self-limiting disease, that should not be treated with antibiotics. Because bacterial resistance is increasing, overprescribing of antibiotics should be avoided. However, it is sometimes difficult to differentiate between the two diagnoses, and guidelines concerning the assessment do not conform. Magnus Falk was my supervisor even during my GP training and encouraged me to continue the scientific research. During my PhD studies, I have come to realize how important it is to do pragmatic studies in a clinical context, especially in primary care, where most patients are managed, and where many have more than one disease.

“…Several studies have demonstrated that in some patients with pneumonia, the disease can be identified on chest CT but not on CR images [1, 4, 5, 7, 10, 11]. Another study showed that in bedridden patients with pneumonia, the diagnostic accuracy of CR is low [6].…”

Background: Data regarding community-acquired pneumonia (CAP) identified on chest computed tomography (CT) but not on chest radiography (CR) are limited. Objectives: The present study aimed to investigate the clinical and radiological features of these patients. Methods: We retrospectively compared the clinical characteristics, etiological agents, treatment outcomes, and CT findings between CAP patients with negative CR and positive CT findings (negative CR group) and those with positive CR as well as CT findings (control group). Results: Of 1,925 patients, 94 patients (4.9%) were included in the negative CR group. Negative CR findings could be attributed to the location of the lesions (e.g., those located in the dependent lung) and CT pattern with a low attenuation, such as ground-glass opacity (GGO). The negative CR group was characterized by a higher frequency of aspiration pneumonia, lower incidences of complicated parapneumonic effusion or empyema and pleural drainage, and lower blood levels of inflammatory markers than the control group. On CT, the negative CR group exhibited higher rates of GGO- and bronchiolitis-predominant patterns and a lower rate of consolidation pattern. Despite shorter length of hospital stay in the negative CR group, 30-day and in-hospital mortalities were similar between the two groups. Conclusions: CAP patients with negative CR findings are characterized by lower blood levels of inflammatory markers, a higher incidence of aspiration pneumonia, and a lower incidence of complicated parapneumonic effusion or empyema than those with positive CR findings. Chest CT scan should be considered in suspected CAP patients with a negative CR, especially in bedridden patients.
