Knowledge, opinions and attitudes of primary care physicians about generic drugs: a cross-sectional study

Pharmacy practice and policy research in Türkiye: a systematic review of literature

Background

In recent decades, there has been an interest in clinical pharmacy practice in Türkiye with emerging studies in this area. Despite the recent emergence of diverse pharmacy practice studies in Türkiye, a comprehensive assessment of overall typology of studies and impact has not been conducted thus far.

Objectives

This systematic review aims to document and assess pharmaceutical policy and practice literature published within the last 5 years in Türkiye. The other aim is to summarise the expected impact of published studies on policy and practice research.

Methods

The systematic review was conducted according to the guidelines described in the PRISMA Statement. A comprehensive search approach, incorporating Medical Subject Headings (MeSH) queries and free-text terms was employed to locate pertinent literature related to pharmacy practice and policy in Türkiye. The search covered the period from January 1, 2019, to January 1, 2024, and involved electronic databases including PubMed, Medline Ovid, Scopus, ScienceDirect, Springer Link, PlosOne, and BMC.

Results

In the final grouping, 73 articles met the inclusion criteria and were selected for this review. Among the quantitative studies, majority studies were cross-sectional survey studies. Through the rigorous thematic content analysis seven research domains were developed from the selected literature: drug utilisation and rational drug use, the emerging role of pharmacist, access to medicines and generic medicines, community pharmacy practice, pharmacovigilance/adverse drug reactions, and pharmacoeconomic studies.

Conclusions

The pharmacist role is evolving; however, several challenges remain in fully realising the potential of pharmacists. These include regulatory barriers, limited public awareness of pharmacists' expanded roles, workforce capacity issues, and the need for ongoing professional development and training. Research studies are needed in the areas of generic prescribing, medicine adherence, intervention studies in community and hospital pharmacy practice, and on pharmacoeconomics and pharmacovigilance.

Importance of a usual source of care in choosing low-priced generic drugs: a cross-sectional study

BACKGROUND

The potential to lower pharmaceutical spending exists if physicians prescribe low-priced generics. This study aimed to empirically investigate the determinants of choosing low-priced generic drugs in South Korea.

METHODS

The 2018 HIRA-NPS dataset was used for this study. Among 1.45 million individuals, we identified the patients who were prescribed atorvastatin 10 mg for more than 60 days in 2018 as the study subjects, separated the subjects into high- and low-priced groups based on their average unit price, and applied a series of logistic regression models to elucidate the factors affecting low-priced drug choice.

RESULTS

Out of 60,984 subjects, only 10,228 (17%) were categorized into the low-priced group. The majority of the subjects (31%) were prescribed drugs at the maximum reimbursement price. Age of the subject, the frequency of visits to the institution, the existence of a usual source of care, and the institution type that a subject mainly visited for prescriptions were associated with being prescribed low-priced generics.

CONCLUSION

The association of being prescribed low-priced generics with the primary care institution and the usual source of care could be interpreted as evidence for the role of primary care in the continuity of patient-centred care. Creating health systems under which professionals act as perfect agents of a patient and/or an insurer is required.

The change of drug utilization in China’s public healthcare institutions under the “4 + 7” centralized drug procurement policy: Evidence from a natural experiment in China

Background: Improving drug accessibility and rational drug use are major challenges for China’s healthcare reform. In 2018, the Chinese government introduced a novel nationwide policy of centralized drug procurement for off-patent drugs, focusing on improving drug utilization patterns of public medical institutions.

Objective: To estimate the impacts of the Chinese centralized drug procurement policy (the so-called “4 + 7” policy) on drug utilization in public medical institutions.

Methods: A retrospective natural experimental design and difference-in-difference method were applied using cross-region data extracted from the national procurement database. Eleven “4 + 7” pilot cities (intervention group) and eleven non-pilot provinces (control group) were matched. In addition, “4 + 7” policy-related drugs (n = 116) were selected as study samples, including 25 drugs in the 4 + 7” procurement List (“4 + 7” List drugs) and their alternative drugs (n = 91) that have not yet been covered by centralized procurement policy. Then, the “4 + 7” List drugs were divided into bid-winning and non-winning drugs according to the bidding results, and they were sorted into generic and original drugs. Defined daily dose (DDD) was used to standardize the quantity of drugs used.

Results: In the 1-year procurement period, the overall completion rate of agreed procurement volume reached 191.4% in pilot cities. Owing to policy impact, the consumption increased by 405.31% in bid-winning drugs (β = 1.62, p < 0.001) and decreased by 62.28% (β = −0.98, p < 0.001) in non-winning drugs. The overall use proportion of bid-winning drugs increased from 17.03% to 73.61% with statistical significance (β = 1.48, p < 0.001), and increments were also detected in all healthcare settings, regions, and anatomical therapeutic chemical (ATC) categories (all p-values < 0.05). Generics and originators were detected with 67.53% increment (β = 0.52, p < 0.001) and 26.88% drop (β = −0.31, p = 0.006) in consume volume. The use proportion of generics increased from 59.23% to 78.44% with significance (β = 0.24, p < 0.001), as well as in tertiary hospitals (β = 0.31), secondary hospitals (β = 0.23), and primary healthcare centers (β = 0.11) (all p-values < 0.001). The use proportion of relatively quality-guaranteed drugs (i.e. bid-winning and original drugs) increased from 56.69% to 93.61% with significance (β = 0.61, p < 0.001), and similar increments were also detected in all healthcare settings, regions, and ATC categories (all p-values < 0.05).

Conclusion: Healthcare providers demonstrated good compliance with the “4 + 7” policy in completing contracted procurement volume. Centralized drug procurement policy promoted drug consumption gradually concentrated on bid-winning drugs, generic drugs, and more importantly, quality-guaranteed drugs.

Changing Characteristics of Pharmaceutical Prices in China Under Centralized Procurement Policy: A Multi-Intervention Interrupted Time Series

Objective: National centralized drug procurement organized by the Chinese government currently represents the largest group purchasing organization worldwide, to establish a reasonable price formation mechanism. This study aimed to evaluate the effects of centralized procurement policy on drug price and price ratio in China.

Method: Monthly drug procurement data of public medical institutions were extracted from the national procurement database, including 11 pilot cities and 36 months from January 2018 to December 2020. Centralized procured INNs (International Nonproprietary Names) (n = 25) and their alternative INNs (n = 96) were selected as study samples. Centralized procured INNs were divided into bid-winning and non-winning products according to the bidding results. Drug price, price distribution, and price ratio were measured. Multi-intervention interrupted time series analysis was performed to estimate the policy impacts in two centralized procurement periods.

Results: The price of centralized procured INNs showed an immediate drop of 44.57% (β = -0.59, p < 0.001) at the policy implementation, among which bid-winning drugs decreased by 61.71% (β = -0.96, p < 0.001). No significant change in the price level or trends was found for non-winning products and alternative drugs in the first-year procurement period (all p-values > 0.05). During the second-year procurement period, alternative drugs in four therapeutic categories detected significant increases in the price level (all p-values < 0.05). The overall coefficient of variation of price distribution exhibited upward trends after policy implementation. Among the most centralized procured INNs, the price ratio between certificated generics (generics that have passed the consistency evaluation) and original drugs declined significantly after policy intervention (p < 0.05), whereas the price ratio between uncertificated and certificated generics increased significantly (p < 0.05).

Conclusion: Chinese government-organized group purchasing resulted in prominent price reduction of bid-winning drugs. The policy observed a short-term “spillover” effect of synergistic price reduction, while the effect wore off after 1-year procurement period. The extremely dispersed price distribution, as well as unreasonable price ratios, requires further effective price regulation means.
