Abstract:
Objective:To evaluate the effectiveness of syncope unit in improving the diagnosis efficiency and treatment prognosis of patients with suspected syncope.Methods:The standardized syncope unit was established in the Affiliated Nanyang Second General Hospital of Xinxiang Medical College in 2018. Patients with suspected syncope attending from November 2018 to April 2019 (before the establishment of syncope unit) and from May to October 2019 (after the establishment of syncope unit) were enrolled in the study. There were 109 cases attending before the establishment of syncope unit (control group) and 126 cases attending after establishment (syncope unit group). The positive rate of examination, the treatment and its cost before and after the establishment of syncope unit were compared. After one year, the follow-up rate, recurrence rate, rehospitalization rate, treatment satisfaction and quality of life of patients were documented and compared between two periods.Results:The positive rates of tilt table test [61.90%), Holter monitoring [64.29%(81/126)], exercise stress test [7.14%(9/126)] invasive electrophysiology [40.48%(51/126)], cardiac imaging [9.52%(12/126)] and 24-h blood pressure monitoring [55.56%(70/126)] in syncope unit group were significantly higher than those in control group [44.95%(49/109), 36.70%(40/109), 5.50%(6/109), 10.09%(11/109), 2.75%(3/109) and 40.37%(44/109); χ2=19.28, 23.11, 6.93, 28.18, 15.85 and 11.61,respectively; all P<0.01]. The diagnostic rate of etiology in syncope unit group was significantly higher than that in control group [87.30%(110/126) vs. 77.06%(84/109), χ2=21.70, P<0.01].The time from onset to cardiac assessment and hospitalization time in syncope unit group were significantly shorter than those in control group[(3.68±1.93)h vs. (7.31±2.64)h;(6.17±1.52)d vs. (10.83±2.09)d]. The hospitalization rate [3.17%(4/126) vs. 8.26%(8/109)], hospital mortality [0.79%(1/126) vs. 2.75%(3/109)] and treatment cost [(4.91±1.14) thousands Yuan vs. (7.05±2.53) thousands Yuan] in syncope unit group were significantly lower than those in control group ( t=14.49, P<0.01; t=8.62, P=0.02;χ2=15.83, P<0.01;χ2=10.03, P=0.01; t=6.17, P=0.03).The outpatient follow-up rate [82.54%(104/126)] and treatment satisfaction rate [91.35%(95/104)] in syncope unit group were significantly higher than those in control group [61.47%(67/109) and 64.18%(43/67)]; and the recurrence rate [14.42%(15/104)] and rehospitalization rate [7.69%(8/104)] in syncope unit group were significantly lower than those in control group [40.30%(27/67) and 23.88%(16/67)](χ2=17.30, 20.37, 18.56, 15.08,all P<0.01). The scores of psychological status, physiological status, environmental status, social relations and overall quality of life in contral group were significantly lower than those in syncope unit group (43.62±12.84 vs. 59.13±13.95,43.10±11.31 vs. 5.86±12.09,52.35±12.76 vs. 63.58±13.05,54.87±12.08 vs. 67.91±14.23,58.42±11.87 vs. 69.28±13.51; t=7.74, P=0.03; t=7.50, P=0.03; t=8.66, P=0.02; t=9.77, P=0.01; t=8.46, P=0.02, respectively). Conclusion:The establishment of standardized syncope unit is helpful to improve the diagnosis efficiency and the prognosis of patients with suspected syncope, and also reduce the cost of diagnosis and treatment.
