[Influences of intervention on the abilities of detecting pulmonary tuberculosis cases in general hospitals].
OBJECTIVE
To explore the influences of intervention on the abilities of detecting pulmonary tuberculosis cases in general hospitals.


METHODS
We selected 6 general hospitals at 3 different levels (A, B, and C). The intervened group included hospitals A1, B1, and C1, and the non-intervened group included hospitals A2, B2, and C2. The results after intervention were compared.


RESULTS
The report rate of pulmonary tuberculosis, sputum positive rate of reported cases, and sputum check rate of reported cases were significantly higher in hospital A1 than grouping hospital A2 (P = 0.000, P = 0.045, and P = 0.017, respectively). The report rate and sputum examination rate of reported cases were significantly higher in hospital B1 than grouping hospital B2 (P = 0.000, P = 0.024, respectively). The report rate and sputum examination rate of reported cases were significantly lower in hospital C1 than grouping hospital C2 (P = 0.000, P = 0.001, respectively). In hospital A1, the report rate, sputum positive rate of reported cases, and sputum check rate of reported cases were not significantly different before and after intervention (P = 0.182, P = 0.116, and P = 0.583, respectively). In hospital B1, the report rate were significantly different before and after intervention (P = 0.004), while the sputum positive rate of reported cases and sputum check rate of reported cases were not significantly different (P = 0.909, P = 0.052, respectively). In hospital C1, the report rate was significantly higher after intervention (P = 0.025). In hospital C2, the sputum check rate significantly increased (P = 0.000).


CONCLUSIONS
Intervention influences the hospitals abilities to detect pulmonary tuberculosis cases. However, more optimized and long-term intervention mechanism should be established to increase case detection rate of pulmonary tuberculosis.
