Objective To evaluate the utilization status of essential medicines at community health centers,and analyze problems existing in the stocking and application situation of such medicines,hence to provide references and suggestions for the implementation of the Essential Medicine System.Methods The investigation method was used to analyze the actual stocking situation of essential medicines at community health centers,and existing problems in implementing the Essential Medicine System.Results An average of 377 species of essential medicines were stocked by the community health institutions, accounting for 53.9% of Beijing Essential Medicine List,and average 61.6% of the total medicines in these institutions.There were insufficiencies existing both in the list and supplies of essential medicines. First-aid and low-price essential medicines are out of stock.Lack of confidence by some patients on the drug brands and their quality covered in the essential medicines.Conclusions The list and supplies of essential medicines could not meet the demand of patients at community health centers adequately.The method of evidence-based practice should be applied to each area in implementing of the Essential Medicine System.

OBJECTIVE:To explore pharmacist's cognition on the factors affecting the drugstore-based pharmaceutical care(PC),and to discuss the relationship between the influencing factors and the influencing degree of these factors on pharmacists.METHODS:A questionnaire survey was carried out among pharmacists in drugstores in Xi'an city and a structural equation modeling(SEM)was formed to verify the factors affecting the drugstore-based PC.RESULTS:The questionnaire survey response rate was 84.7%(133/157).The data obtained fit the theoretical model satisfactorily.Partial of the hypotheses have been proved.CONCLUSIONS:According to SEM testing results,the development of trade were positively related to drugstore;drugstore has a direct positive impact on social evaluation,the practice of basic PC and advanced PC in drugstores;the quality of pharmacists has a direct positive impact on the social evaluation and the practice of advanced PC in drugstores.

OBJECTIVE:To study the current situation of development in personnel resources of licensed pharmacists of drug supply enterprises in China and the ways of development.METHODS:The existing problems in the development of per-sonnel resources of licensed pharmacists were analyzed through the ways of questionnaires and interviews.RESULTS&CONCLUSIONS:The drug supply enterprises lacked collocation and application rules of pharmacists and there lacked a system for employing,training,assessing and encouraging the licensed pharmacists.Furthermore,because of the inefficient policy,the supply-demand market of licensed pharmacists was unsatisfactory and the functions of the pharmacists were incomplete.Therefore,the practicing environment for the licensed pharmacists must be optimized.It is recommended that a perfect system of employment and assessment should be established;the full-time practice and the part-time practice should be allowed to coexist;the information network platform for supply-demand of the licensed pharmacists should be set up to improve the management as well as self-discipline function of licensed pharmacist association,better the further education system,and therefore promote the development of personnel resoures.
