Application of individualized rational drug use monitoring platform in promoting rational drug use of patients with chronic diseases / 中国药房

OBJE CTIVE To provide reference for improving rational drug use in medical institutions and strengthening individualized rational drug use monitoring. METHODS The hospital information system （HIS）was used to retrieve the patient ’s medical information and the doctor ’s medical information ；on the basis of pre-examination of prescriptions ，the chronic disease medication monitoring and visiting frequency monitoring modules were added to construct individualized rational drug use monitoring platform. Taking hypoglycemic drugs as an example ，the number of patients who were prescribed the drug ≥3 times a month in Karamay Central Hospital （hereinafter referred to as “our hospital ”）was compared before and after the operation of the individualized rational drug use monitoring platform （Jan. to Apr. 2018 regarded as before operation ，Jan. to Apr. 2019 and 2021 regarded as after operation ）. At the same time ，the number of risk prescriptions （repeatedly prescribing the same drug ≥3 times a day）and unreasonable prescriptions after the operation of the individualized rational drug use monitoring platform （Jan. to Apr. 2019 and Jan. to Apr. 2021）in our hospital were compared. RESULTS The proport ion of patients who were over prescribed Diformin tablets from Jan. to Apr. in 2021 was lower than the same period in 2018 significantly（16.65％ vs. 27.17％，P＜0.05）. From Jan. to Apr. 2019，35.3％ of the risk prescriptions in our hospital were unqualified prescriptions ；in the same period of 2021， the proportion of unqualified prescriptions in risk prescriptions in our hospital decreased to 12.82％ ，which was statistically significant compared with 2019（P＜0.05）. CONCLUSIONS Based on the actual situation of patients ，our hospital establishes the individualized rational drug use monitoring platform by using HIS to meet the actual needs of clinical drug use. The use of the platform has significantly reduced the number of patients visiting doctors many times and unreasonable prescriptions ，and promotes rational drug use. At the same time ，the platform also further strengthens the prescription review system of our hospital and improves the level of pharmaceutical care.

Kramers escape rate in nonlinear diffusive media.

In this paper, we study nonlinear Kramers problem by investigating overdamped systems ruled by the one-dimensional nonlinear Fokker-Planck equation. We obtain an analytic expression for the Kramers escape rate under quasistationary conditions by employing a metastable potential and its predictions are in excellent agreement with numerical simulations. The results exhibit the anomalies due to the nonlinearity in W that the escape rate grows with D and drops as mu becomes large at a fixed D. Indeed, particles in the subdiffusive media (mu>1) can escape over the barrier only when D is above a critical value, while this confinement does not exist in the superdiffusive media (mu<1).
