OBJECTIVE To evaluate the effects of pharmaceutical interventio n led by clinical pharmacists on medication appropriateness of elderly inpatients. METHODS A non-randomized concurrent controlled trial was carried out. Elderly patients admitted to two treatment groups in the geriatric department of Yancheng First People ’s Hospital since June 2021 were selected as the research objects. According to the inclusion and exclusion criteria ，the first 40 patients were selected from each of the two treatment groups （according to the order of admission time ）and set as the control group or the intervention group. The control group received routine treatment and nursing services ，and the intervention group additionally received pharmaceutical intervention led by clinical pharmacists on the basis control group. Clinical pharmacists found potential inappropriate medication （PIM）and put forward suggestions on optimization of medication regimen. American Geriatrics Society 2019 Updated AGS Beers Criteria ® for PIM Use in Older Adults （hereinafter referred to as “Beers criteria ”）and the Criteria of PIMs for Older Adults in China 2017 Edition （hereinafter referred to as “Chinese criteria ”）were used as reference tools for drug use review. The medication appropriateness index （MAI）total scores （main evaluation indicator ），the number of PIMs ，the number of drugs used ，the length of hospital stay ，the number of drug-related adverse events during hospital stay ，the number of drug regimen optimization suggestions by pharmacists ， and implementation rate of E-mail：zhihuadou@163.com optimization suggestions adopted by clinicians were compared between 2 groups at admission and at discharge. RESULTS At admission ，there were no statistically differences in MAI total scores，the number of PIMs based on Beers criteria ，the number of PIMs based on Chinese criteria or the number of drugs used between 2 groups（P＞0.05）. At discharge ，there were no statistically differences in the number of PIMs based on Chinese criteria and the length of hospital stay between 2 groups（P＞0.05），but the MAI total scores ，the number of PIMs based on Beers criteria and the number of drugs used in the intervention group were lower than those in the control group （P＜0.05）. In the intervention group，the proportion of drugs recorded as “inappropriate medication ”at admission （34.5％）was significantly higher than that at discharge（19.5％）（P＜0.05）. The difference between the number of drugs discharged from hospital and the number of drugs admitted to hospital in the control group [ 3（1-4.8)] was significantly higher than that in the intervention group [ 1（0-2.8)]（P＝ 0.012）. Compared with admission ，the proportion of drugs recorded as “inappropriate medication ”in the intervention group at discharge was significantly decreased on the basis of “effectiveness”dimension and “course”dimension （P＜0.05）. During hospitalization，clinical pharmacists put forward 70 optimization suggestions of drug regimen for the intervention group ，among which 39 suggestions were adopted and implemented by clinicians ，with an implementation rate of 55.7％. CONCLUSIONS The pharmaceutical intervention led by clinical pharmacists can improve overall appropriateness of drug use in the elderly inpatients using MAI as main evaluation indicator.

To eliminate viral hepatitis as a public health threat, the World Health Organization has set the ambitious goal of reducing the prevalence of hepatitis B surface antigen (HBsAg) in children to 0.1% by 2030, and the key to this grand goal is cutting off hepatitis B virus (HBV) transmission from mother-to-child. Previously, national and international guidelines for the management of chronic hepatitis B recommended the use of hepatitis B vaccine and hepatitis B immunoglobulin (HBIG) or combination of any in neonates and antiviral drugs for pregnant women with high viral load in late pregnancy. However, a recent study in Thailand found that the addition of antiviral drugs in pregnant women with high viral load in the third trimester did not significantly lower the incidence of mother-to-child HBV transmission, but no case of chronic HBV infection was seen with strict standards hepatitis B vaccine and HBIG combined immunoprophylaxis and the use of tenofovir disoproxil in pregnant women with high viral load in the third trimester. In addition, the incidence of mother –to- child transmission of HBV in the antiviral group was 0, while the incidence of HBV transmission in the placebo group was 2%. Therefore, it is not possible to deny the efficacy of adding antiviral drugs in treating pregnant women with high viral load in the third trimester with combined immunoprophylaxis. There is an urgent need for more real-world studies in clinical practice to further reveal the principles and existing problems of mother- to- child transmission of HBV.
