Mediating role of inner strength in the relationship between medication literacy and medication adherence among kidney transplant patients

Objective:Compared with long-term renal replacement therapy,kidney transplantation is the ideal treatment for end-stage renal disease(ESRD),significantly extending patient life and improving quality of life.Kidney transplant patients need to adhere to lifelong immunosuppressive medication regimens,but their medication adherence is generally poor compared with other organ transplant recipients.Medication adherence is closely related to medication literacy and psychological status,yet related studies are limited.This study aims to investigate the current status of medication adherence,inner strength,and medication literacy in kidney transplant patients,analyze the relationships among these 3 factors,and explore the mediating role of inner strength in the relationship between medication literacy and medication adherence.Methods:A cross-sectional survey was conducted from March to October 2023 involving 421 patients aged≥18 years who visited kidney transplantation outpatient clinics at 4 tertiary hospitals in Hunan Province.The inner strength,medication literacy,and medication adherence of kidney transplant patients were investigated using the Inner Strength Scale(ISS),the Chinese version of the Medication Literacy Assessment in Spanish and English(MedLitRxSE),and the Chinese version of the Morisky Medication Adherence Scale-8(C-MMAS-8),respectively.Univariate analysis was performed to examine the effects of demographic and clinical data on medication adherence.Correlation analysis was conducted to explore the relationships among medication literacy,medication adherence,and inner strength.Significant variables from univariate and correlation analyses were further analyzed using multiple linear regression,and the mediating effect of inner strength was explored.Results:Among the 421 questionnaires collected,408 were valid,with an effective rate of 96.91%.The scores of C-MMAS-8,MedLitRxSE,and ISS were 6.64±1.16,100.63±14.67,and 8.47±4.03,respectively.Among the 408 patients,only 86(21.08%)patients had a high level of medication adherence,whereas 230(56.37%)patients had a medium level of medication adherence,and 92(22.55%)patients had poor medication adherence.Univariate analysis indicated that the kidney transplant patients’age,marital status,education levels,years since their kidney transplant operation,number of hospitalizations after the kidney transplant,and adverse drug reactions showed significant differences in medication adherence(all P<0.05).Correlation analysis showed that inner strength positively correlated with both medication literacy(r=0.183,P<0.001)and medication adherence(r=0.201,P<0.001).Additionally,there was a positive correlation between medication adherence and medication literacy(r=0.236,P<0.001).Inner strength accounted for 13.22%of the total effect in the mediating role between medication literacy and medication adherence.Conclusion:The level of medication adherence among kidney transplant patients needs improvement,and targeted intervention measures are essential.Inner strength mediates the relationship between medication literacy and medication adherence in these patients.Healthcare professionals should focus on enhancing medication literacy and supporting patients’inner strength to improve medication adherence.

《小品方》方药服量控制策略与服药方法的文献研究

目的探析陈延之《小品方》中方药服量的控制策略与方法。方法纳入《小品方》中方名、主治病症、药物组成、方药剂量及煎服法均完整辑录的内服方剂,并运用描述性分析对所纳入的数据进行频次统计与归纳总结。结果共纳入内服方剂194首。汤剂单次服量为30~1200 ml,以300 ml最多见,约占汤剂单次服量总频次的46.19%。散剂单次服量为0.10~15 g,以5 g最多见,约占散剂单次服量总频次的64.29%。丸剂单次服量为0.02~6 g,以2 g最多见,约占丸剂单次服量总频次的34%。服药次数为2日1服~日7服,各剂型均以日服3次最为常见,约占3种剂型日服次数总频次的68.15%。服药时间以定时服药为主,但据病情轻重、病理特点与人体生物节律等不同,有汤剂顿服、平旦服药及昼夜连服等特殊服法。结论《小品方》强调多因素综合作用下机体对于药物耐受性与敏感性的差异是决定服量轻重的关键。其通过对方药的单次服量及服药间隔时间的调整,增强了服法对于方药绝对服量的控制。

Aspirin-induced small bowel injuries and the preventive effect of rebamipide

AIM:To evaluate the influence of taking low-dose aspirin for 4 wk on small intestinal complications and to examine the preventive effect of rebamipide.METHODS:This study was conducted as a single-center,randomized,double-blind,cross-over,placebo-controlled study.Eleven healthy male subjects were enrolled.Each subject underwent video capsule endos-copy after 1 and 4 wk of taking aspirin and omepra-zole,along with either rebamipide or placebo therapy.The primary endpoint was to evaluate small bowel damage in healthy subjects before and after taking low-dose aspirin for 4 wk.RESULTS:The number of subjects with mucosal breaks(defined as multiple erosions and/or ulcers)were 1 at 1 wk and 1 at 4 wk on the jejunum,and 6 at 1 wk(P = 0.0061)and 7 at 4 wk on the ileum(P =0.0019).Rebamipide significantly prevented mucosal breaks on the ileum compared with the placebo group(P = 0.0173 at 1 wk and P = 0.0266 at 4 wk).CONCLUSION:Longer-term,low-dose aspirin adminis-tration induced damage in the small bowel.Rebamipide prevented this damage,and may be a candidate drug for treating aspirin-induced small bowel complications.
