As the medical industry continuously raises its demands for efficiency and quality, hospital performance management has gradually become the focus of reform. The Resource-based Relative Value Scale (RBRVS) evaluation system, as an effective performance evaluation tool, has been adopted and implemented by numerous hospitals both domestically and internationally. Based on the analysis of the current status of performance reform using RBRVS in hospitals at home and abroad, this article comprehensively introduces the origin, development, and basic principles of RBRVS. Furthermore, it provides an evaluation of the difficulties encountered in the practical application of this system and suggests optimization measures.
ObjectiveTo investigate the positive rates of virulence genes ply, lytA and nanA in Streptococcus pneumoniae (SP) strains isolated from different sources and the pathogenesis.MethodsA total of 147 and 24 strains of SP were isolated from sputum and blood samples of hospitalized children in Tongji Hospital of Wuhan from 2015 to 2016, respectively. Such strains of SP were analyzed by automated microbial analyzer VITEK Compact-2 and confirmed by its specific gene pbp2B using regular polymerase chain reaction (PCR) method. Then PCR method was used to detect the carriers of the virulence genes ply, lytA and nanA, and calculated the fatality and hospitalization days of patients.ResultsPositive rates of virulence genes ply, lytA and nanA were 95.9%, 96.6% and 88.4% respectively for 147 strains isolated from sputum, and were 100.0%, 100.0% and 79.2% respectively for those from blood. Between the 147 children with pneumonia and 24 children with septicemia, there was no statistically significant difference in fatality [ 8.3% (2/24) vs. 0.7% (1/147), P=0.052], but there was a significant difference in length of hospital stay [(14.2±2.4) vs. (6.4±1.5) d; t=21.303, P<0.001].ConclusionsThe positive rate of SP virulence gene nanA is lower than those of ply and lytA. The positive rates of SP virulence genes ply, lytA and nanA are similar from different sources. Significant difference may be found for hospitalization days among different types of SP infections.
