The fibrosing pattern of NSIP has a five-year survival rate of 86% to 92%, while the cellular pattern of NSIP has a 100% five-year survival rate. Patients with NSIP (whether cellular or fibrosing), have a better prognosis than those with usual interstitial pneumonia (UIP). [4]
Necrotizing pneumonia (NP), also known as cavitary pneumonia or cavitatory necrosis, is a rare but severe complication of lung parenchymal infection.

The rates of community acquired pneumonia vary by country, but there is an estimated one million people hospitalized in Europe due to this condition per year. Hospital acquired pneumonia has an incidence rate of about .05-2% and has the highest mortality rates of any infection. [22]
Desquamative interstitial pneumonia has a favourable prognosis and most patients improve with proper treatment. The mortality rate of DIP is between 6 and 28%. [22] The survival rate of DIP is estimated to be between 68% and 94%. Without treatment around 60% of patients get worse.
Since pneumonia can take a dangerous turn, it's important to know the earliest signs of it. Dr. Zweig says that, typically, pneumonia starts as a regular viral upper respiratory infection.
