Objective To explore the medical insurance quota payment of dialysis treatment for outpatients with end-stage renal disease in Chengdu from following aspects, evaluation indexes and reasonable amount, so as to provide scientific basis for the payment of single disease. Methods A questionnaire survey was conducted to collect the cost information of patients, and to formulate the assignment of evaluation indexes according to the therapeutic principles and statistical results; Delphi method was adopted to determine the assignment and the standard of quota payment. Results A total of 17 dialysis organizations approved by Chengdu municipal medical insurance were involved in this study. Of 700 questionnaires distributed, 686 were retrieved. After excluding 26 questionnaires for incomplete filling and incorrect treatment information, a total of 660 questionnaires were included actually, accounted for 94.28% of all informants. The results of survey showed that, the hemodialysis treatment rate accounted for 84% (555/660) of all informants, while the peritoneal dialysis treatment rate accounted for 16% (105/660). By assessing the project assignment of outpatient dialysis treatment, the minimum annual payment of hemodialysis was RMB 118 242.75 yuan, while that of peritoneal dialysis was RMB 96 498.00 yuan. Conclusion The quota payment of outpatient dialysis shows b evidence after adopting the treatment project assignment. The grading quota payment of outpatient dialysis enables the medical insurance fund to be more reasonably used.
Objective To investigate the relationship of resonant frequency and low frequency conductive hearing loss. Methods Eighty- four participants were included, and tested by gold standard and resonant frequency respectively. Receiver operator characteristic (ROC) curve was used to explore the most appropriate cutoff point for diagnosing low frequency conductive hearing loss and Levene’s test was used to test the difference of the low frequency conductive hearing loss and normal hearing groups. Results The resonant frequencies of low conductive frequency hearing loss and normal hearing groups were different. The optimum cutoff points of resonant frequency were 850Hz and 1 050Hz. The resonant frequency range from 850Hz to 1 050Hz was considered normal. The test was powerful when the resonant frequency was lower than 850Hz. The test was powerless when the resonant frequency was higher than 1 050Hz. Conclusions Conductive hearing loss could be predicted from resonant frequency when it is lower than 850Hz. The test is powerless when the resonant frequency is higher than 1 050Hz. The resonant frequency could be affected by many factors, so ENT (ear, nose and throat) doctors and audiologists have to be careful about how to explain the results when the resonant frequency is higher than 1 050Hz.
