A cross-sectional survey on two-way referral using self-report questionnaire was conducted in a sample of 1423 residents living in 4 communities in Caobeidian area, Chaoyang District and 4 communities in Dongcheng District from April to July 2009. Among the residents who responded the questionnaire, 19.7% (88/446) from Gaobeidian and 8.2% ( 80/977 ) from Dongcheng District were referred to hospitals in 2008. And 30.7 % (27/88) in Gaobeidian and 43.8% (35/80) in Dongcheng District referred to hospital based on their own decision rather than doctors' recommendation; 45. 5% (40/ 88) in Gaobeidian and 45. 0% (36/80) in Dongcheng District of referrals were officiary processed by health institutions. The survey also showed that 57.6% and 59.4% of the respondents from the two districts preferred to free referral between community health service centers and hospitals.

Objective To investigate the therapeutic effect of different combination regimens on patients with high-frequency sudden sensorineural hearing loss(SSNHL). Methods 82 patients with high-frequency SSNHL from December 2013 to May 2017 were enrolled. The control group was treated with hormone,lidocaine, and genetein combination therapy,while the observation group received systemic hormones,and local hormones combined with hyperbaric oxygen therapy,the average frequency of pure tone valve improvement,complications and adverse reactions in two groups were compared.Results After the treatment,the average pure tone of the two groups was significantly improved than pretherapy(tcontrol group = 10.28,P = 0.00;tobservation group = 11.06, P=0.00),but there was no significant difference in hearing improvement between the two groups(t=0.680,P=0.698),the total effective rate in the control group was 63.41%,in which the observation group was 68.29%,the difference was not statistically significant(χ2=0.230,P=0.816),but the cure rate was 26.83% in the observa-tion group which was higher than that in the control group(7.32%)(χ2=2.05,P=0.040).There was no signifi-cant difference in improvement of complication(tinnitus and ear nausea)between the two groups(χ2Tinnitus =0.000,P=1.000;χ2Aurussion=0.000,P=1.000),and there was no obvious adverse reaction in both groups. Conclusions Treatment of high-frequency SSNHL,hormone and hyperbaric oxygen therapy is good and safe, which can effectively improve the patient′s complication(tinnitus and ear nausea).
