title: A criterion based audit of community-acquired pneumonia.
abstract: We undertook a prospective audit of patients admitted to a specialist respiratory unit in order to assess: (a) the completeness of the objective assessment of severity of community-acquired pneumonia in patients on admission to hospital, and whether such indices were useful in predicting outcome; (b) the completeness of microbiological testing and whether maximizing the number of specimens sent to the laboratory would increase the frequency of positive microbiological diagnoses and; (c) the influence of the above on clinical management. Forty-eight patients with consolidation on chest X-ray were studied in two audit periods: 1 February 1991 to 1 May 1991 and 2 May 1991 to 16 March 1992. After the first audit period, a rubber stamp with a check list of microbiological investigations was used in the patients' notes. Seven 'markers of severity' of pneumonia, were recorded consistently throughout the study and these were useful in predicting outcome (P < 0.01). In the first audit period sputum culture, blood culture and acute serology were recorded in approximately 50% of patients. Following the introduction of the rubber stamp, the requesting of sputum, blood and urine antigen rose from none in the first audit period to 40-60%. The increase in the number of specimens obtained was not associated with an increase in the proportion of positive microbiological diagnoses. Clinical management was altered in 10 patients because of the microbiological reports and in four patients with negative microbiology (chi2 = 8.19; P < 0.01).
  
  
  CONCLUSIONS
  The standard of initial assessment was high in this specialist unit, and the presence of two or more 'markers of severity' did help predict outcome. A simple change in work practice resulted in a significant improvement in the thoroughness of microbiological investigations.(ABSTRACT TRUNCATED AT 250 WORDS)
