Drug shortage is a global issue affecting low, middle, and high-income countries. Many countries have developed various strategies to overcome the problem, while the problem is accelerating, affecting the whole world. All types of drugs, such as essential life-saving drugs, oncology medicines, antimicrobial drugs, analgesics, opioids, cardiovascular drugs, radiopharmaceutical, and parenteral products, are liable to the shortage. Among all pharmaceutical dosage forms, sterile injectable products have a higher risk of shortage than other forms. The causes of shortage are multifactorial, including supply issues, demand issues, and regulatory issues. Supply issues consist of manufacturing problems, unavailability of raw materials, logistic problems, and business problems. In contrast, demand issues include just-in-time inventory, higher demand for a product, seasonal demand, and unpredictable demand. For regulatory issues, one important factor is the lack of a unified definition of drug shortage. Drug shortage affects all stakeholders from economic, clinical, and humanistic aspects. WHO established global mitigation strategies from four levels to overcome drug shortages globally. It includes a workaround to tackle the current shortage, operational improvements to reduce the shortage risk and achieve early warning, changes in governmental policies, and education and training of all health professionals about managing shortages.

Background: Resistance to antibiotics is one of the major global health challenges. An adequate understanding of the public regarding rational antibiotic use is a prerequisite to limit progression in antibiotic resistance. This study aimed to investigate the knowledge, attitude, and practices (KAP) of antibiotics and antibiotic resistance among customers visiting community pharmacies. Methods: This study was undertaken in three capital cities in China during March 2019 and July 2019 by using a questionnaire of 28 items. The questionnaire had four parts, including sociodemographic characteristics, KAP about antibiotics, and antibiotic resistance. A systematic random sampling approach was used to recruit the participants. Kruskal–Wallis and Mann–Whitney tests were carried out for data analysis. Results: The response rate was 66.7% (1800/2700). Out of the total, only 9.7% of the customers had good knowledge about antibiotics. Nearly half of the participants were unable to differentiate between antibiotics, and anti-inflammatory drugs (n = 820, 45.6%, Median = 2, IQR = 1). Most of the customers were of the view that the use of over the counter antibiotics in pregnant women is unsafe (n = 1307, 72.6%, Median = 2, IQR = 0). Almost half of the participants disagreed that costly antibiotics are more effective and have fewer side effects (n = 897, 49.9%, Median = 3, IQR = 1). Only 22.3% of participants said that they always finish the course of antibiotic treatment (n = 401, 22.3%, Median = 3, IQR = 1). Conclusion: The knowledge of Chinese pharmacy consumers was inadequate, and a lack of good attitudes and practices in certain aspects of antibiotic use was observed. Educational interventions are needed to increase public knowledge of antibiotics.

Objective The aim of this study was to measure the impact of zero-mark-up drug policy (ZMDP) on drug-related expenditures and use in urban hospitals. Design This was a retrospective observational study of trends in drug expenses and use in the context of the ZMDP using an interrupted time series analysis. Setting Twelve hospitals (three tertiary hospitals and nine secondary hospitals) in Xi’an, which is the capital of Shaanxi Province in Western China. Data and participants The prescription information for all outpatients and inpatients in the study hospitals from January 2016 to April 2018 was used in this study. Interventions The Chinese government announced the policy intervention measure of the ZMDP, which was implemented in all public hospitals as of 1 April 2017. Primary measures Monthly drug expenditures, monthly medical expenditures, the percentage of drug expenditures among total medical expenditures, the average outpatient drug expenditure per visit, the percentage of prescriptions that include an injection and the percentage of prescriptions that include an antibiotic. Results Monthly total medical expenses increased in both tertiary and secondary hospitals after the ZMDP was implemented. In tertiary hospitals, the average outpatient drug expenditures per visit showed a slow decreasing trend before the intervention and an increasing trend after the intervention, with statistically significant changes in both the level (p<0.001) and the trend (p=0.02). Secondary hospitals showed a slow increasing trend both before and after the policy implementation, with no significant change in the trend (p=0.205). The proportion of prescriptions, including injections, was over 20% in secondary hospitals and less than 20% in tertiary hospitals, with no significant changes to this indicator observed after implementation of ZMDP. Conclusions The effect of the ZMDP on drug-related expenditures and use in Chinese public hospitals was not substantially evident. Future pharmaceutical reform measures should give more consideration to physician prescription behaviours.

In this study, we investigated the trends and patterns of antibiotic consumption (macrolides and lincosamides) in China’s healthcare institutions from 2015 to 2017. The China Drug Supply Information Platform (CDSIP) was officially launched in 2015. We collected records from this national centralized bidding procurement system between 2015 and 2017. The use of J01F antibiotics (macrolides or lincosamides) was calculated in a defined daily dose per 1000 inhabitants per day (DID).Purchase data from 70,366 national medical facilities included in the CDSIP were collected. The procurement data of 66,007 medical facilities have not changed over 3 years. There is a slight decline in the consumption of J01F antibiotics, which decreased from 3.03 DID in 2015 to 2.91 DID in 2017. Azithromycin (20.6%) was the most commonly used antibiotic in 2017 among all classes, followed by clindamycin (17.9%) and erythromycin (13.7%). Parenteral antibiotics accounted for 32.0% of total antibiotic consumption and 59.6% of total antibiotics expenditure in 2017. The overall consumption of most antibiotics decreased slightly over the 3-yearstudy period. This may be owing to China’s health-related policies in the past few years. A gap still exists in antibiotic use between regions and dosage forms. Further studies are needed to optimize antibiotic prescribing and reduce antibiotic resistance.

Introduction: Drug shortages pose a serious global public health challenge, affecting China and other countries. Evidence from USA shows that short-supplied drugs demonstrated a very high price growth during and after a shortage. However, the effect of shortages on drug prices in China remains unknown. This paper aims to understand the impact of drug shortages on prices and explore implications for shortage prevention policy.Methods: We collected the purchase prices and delivery rates of 120 drugs from April 2019 to December 2021 across whole China. We examined price progression of affected drugs using linear mixed-effects models and performed subgroup analyses based on the number of manufacturers and the severity of shortage.Results: Non-shortage cohort had an annual price growth of 11.62% (95% confidence interval [CI] 8.34 to 14.98). Shortage cohort demonstrated an annual price growth of 8.08% (95%CI 0.12 to 16.77) in the period preceding a shortage, 27.57% (95%CI 6.17 to 52.87) during a shortage, and 9.38% (95%CI −12.64 to 36.39) in the post-shortage period. Drug shortages’ impact on prices varied across subgroups. Compared with that of drug markets supplied by a single manufacturer, the price growth rate of markets supplied by more than one manufacture declined more after the shortage resolution.Conclusion: Shortages resulted in significant price increases of study markets, especially the low-priced markets, while the shortage resolution slowed the growth. The primary shortage driver has shifted from the low price to others drivers, such as unavailability of active pharmaceutical ingredients. For currently sole-supplied drugs, the expedited review of applications from other manufacturers should be considered.

Objective To ensure the availability of quality pharmaceutical products and effective pharmaceutical services, a package of interventions named auditable pharmaceutical transactions and services (APTS), was implemented in the tertiary and secondary hospitals across Ethiopia since 2014. This study aimed to evaluate outpatients’ perception of pharmaceutical service quality in hospitals with APTS in Ethiopia. Design Cross-sectional study. Setting Seven hospitals of Tigray, Ethiopia. Participants 794 patients coming for pharmaceutical services. Main outcome measures SERVQUAL instrument was employed to collect the patient’s perception of pharmaceutical services. The mean perception score of pharmaceutical service quality was the main outcome measurement. Results Out of 810 patients approached, 794 participated in the study (response rate of 98.02%). Overall, the mean perception score of the service quality was 3.1 of 5. Among the five dimensions of SERVQUAL, dimension of empathy achieved the highest result with a mean score of 3.71, and tangibility was the second (3.19), followed by responsiveness (3.08), assurance (2.87) and reliability (2.81). The perception of patients in tertiary hospitals of service quality was more positive compared with patients in secondary hospitals (3.265>3.011, p=0.04). However, the difference was only significant in the dimension of assurance when considering the five dimensions separately. Respondents who were older, widowed, illiterate, farmer, retired or Orthodox were found to have better quality service experience compared with others (p=0.001). Conclusion Generally, outpatients’ perception of pharmaceutical service quality was positive. However, two dimensions of the service quality (assurance and reliability) were negatively perceived. To improve the service quality, we recommended the following: (1) managers should provide more training for pharmacists to strengthen their professional knowledge and encourage them to cooperate with other professionals; (2) the government needs to develop guidelines on information provided to patients and train the pharmacists to follow them; (3) hospitals can apply various procurement methods and efficient inventory management methods.
