INTRODUCTION

Given the increasing costs of health system management and health care service delivery, utilizing the principles of health economics is inevitable. The World Health Organization report in 2000 highlights the importance of strategic purchasing as the primary strategy to achieve the goals of every health system 1. In line with the efforts made to achieve the major goals of the health system in all countries, strategic purchasing is one of the most important components of the financing structure in the health system; it must be implemented in a way that it would provide cost-effectiveness, quality, and high level of efficiency 2.

Strategic purchasing is the active and evidence-based interaction to achieve the major health goals via increasing the volume and quality of services provided 1. This type of purchase in the health system seeks to find effective, high quality, and cost-effective services from the best providers. The best framework for evaluating the performance of strategic purchasing is the model presented by the World Health Organization (WHO) in the report published in 2000 (Figure 1) that is accepted by all health care system researchers and health policy makers around the world. This framework can be used to assess the status of quality in strategic purchasing 4.

Undoubtedly, observing quality in these five dimensions can have a significant impact on the quality of health care delivery in the community. Hence, according to the definition presented by the World Health Organization (WHO), strategic purchasing in this area is an important component that is always looking for methods to decide in the five domains including: What to be purchased? For whom to buy? From whom should be purchased? How much to pay? How to pay?

A small number of studies have been conducted on the quality of services in strategic purchases to improve the coverage of health care services in several African countries 5. In addition, it has also been considered in European countries 6.

In order to improve access to quality health care services in the health care systems of different countries, many interventions has been conducted in these systems and they have provided a higher level of efficiency in proportion to the resources and costs spent. It is a way to provide new resources for the delivery of effective quality health care services 3,5.

Many studies have investigated different components of strategic purchasing. Given the impact of quality status on different domains of strategic purchasing, this study was conducted as a systematic review aimed at investigating the status of quality in strategic purchasing in the health systems.

METHODS

In this study, five scholarly databases were used including ProQuest, EBSCO, Scopus, PubMed, and the Web of Science. The mentioned databases were chosen because of their comprehensiveness and consistency with the objective of the study. To ensure the quality, the search was primarily focused on the finding of peer-reviewed journal articles; however, research reports, monographs, and edited collections of academic papers were also included because they also undergo a similar process of peer review.

Procedure:

This systematic review study was conducted based on the components of the Protocol of Systematic Reviews and Meta-analysis (PRISMA). Accordingly, an electronic search was conducted on articles published from 2000 to October 2019.

Search strategy: The search strategy was as follows.

Search Engines and Databases: Google, Google Scholar, PubMed, ProQuest, EBSCO,ISI web of science, Scopus, Science Direct, MAGIRAN, Scientific Information Database, Iran doc (2000 to present)

Search in Embase: ('health care delivery'/de OR 'health service'/de) AND 'health care quality'/de AND 'strategic purchasing'.

In this study, a data extraction form was used to collect data from previous studies (data collection form). The form was used to maintain integrity, reduce bias, and increase the validity and reliability of data collected via systematic review. To conduct the study, first, the list of main keywords consistent with the objective of the research was prepared by the research team in both English and Persian, and then the above mentioned databases were searched. The data collection form was completed using the data existing in the sources of information.

Inclusion and exclusion criteria: The search was conducted on the papers published from 2000 to October 2019 and only English articles relevant to the objective of the review were included in the study. In order to enrich the quality of data, only articles that were mainly focused on the quality of strategic purchasing in the health system and their full text were available were reviewed. Editorial notes, letters to the editor, book reviews, as well as books were excluded from the study.

Evaluation of articles: Evaluation was performed by four researchers, including two assistant professors and two researchers, all with a rich research background. They reviewed the articles’ titles and abstracts and tagged them in the endnotes software. The full articles were reviewed by researchers based on inclusion and exclusion criteria. Studies on strategic purchasing and procurement in the fields other than the health systems were excluded due to non-compliance with the study objectives.

Data extraction and analysis: The data extraction form was used to collect different data including the name of the first author, year of publication, type of study design, study population, the objective of the study, and the outcome of the study regarding strategic purchasing for the delivery of quality services.

RESULTS

After searching the databases, 256 articles were selected and then duplicates were removed. Of all the selected articles published on strategic purchasing, 11% had assessed quality. A total of 16 articles had investigated the quality and the results are presented in the following PRISMA flowchart (Figure 2).

Figure 2 Literature review and data extraction flowchart 

The results of the review in this study showed that different domains of strategic purchasing were addressed as follows: “What to be purchased?” in 5 cases (31.3%); “For whom to buy?” in 8 cases (43.6%); “From whom should be purchased?” in 11 cases (68%); “How much to pay?” in 9 cases (56.3%); and “How to pay?” in 7 cases (44%) (Table 1).

DISCUSSION

The results of the review of studies showed that only 11% of the selected papers addressed quality in strategic purchasing. It indicates the lack of focus on the quality of studies conducted in the field of strategic purchasing. Of the 24 articles that examined the status of quality in strategic purchasing, 16 articles dealt with one aspect of strategic purchasing. The review of the first domain of strategic purchasing, i.e. “What to be purchased?” in the category of “Benefit package”, five articles assessed the delivery of a variety of service packages 7,8,13,17,21. This domain was investigated in a study in the Philippines that was conducted on this type of purchase. Since both the government and the private sector provide health care services in the Philippines, the issue of purchasing low-cost and high-coverage services had been a part of the strategic purchasing agenda, it had been suggested to deliver quality service packages for middle-income population groups by private insurers and private centers 12. In Iran, this issue has been addressed by developing health insurance for all members of the community 22.

In the domain of “For whom to buy?” in the category of “Demand side”, seven out of 16 articles assessed target populations in need of strategic purchasing packages. These articles emphasize the establishment of support mechanisms for vulnerable and poor groups in the community 5,9,10,12,15,16,17. This issue had been addressed in the Philippines and Malaysia by focusing on the delivery of quality services to the poor and middle-income population groups.

Among the five domains of strategic purchasing, the domain of “From whom should be purchased?” in the category of “Supply-side” was the most addressed domain with 11 articles (68.5%). This group of the study investigated appropriate platforms for purchasing quality products and services 5,9,10,12,13,14,15,16,17,20,21. The significant focus on this domain might be attributed to the fact that health policymakers are mainly willing to buy from those who have better quality products.

Concerning the domain of “How to pay?” in the category of “Payment method”, nine articles investigated methods of purchasing and paying for the quality services provided. It may indicate that the topic of fulfilling health care needs in a strategic purchase is closely related to the quality of services required 5,7,8,10,11,12,13,17,18. In a study conducted in Hong Kong on government-run Hong Kong-funded hospitals, the researchers investigated a performance-based payment system (P4P) that had been utilized for strategic purchasing and allocating population-based funds. Given that almost 60% of the budget had been allocated for developing services and the rest had been dedicated to improving the quality of services, a quality-based payment incentive program had been proposed 18.

Concerning the domain of “How much to buy” in the category of “Price” in strategic purchasing, six articles examined quality in creating sustainable financial resources and cost management; they concluded that neglecting a reasonable amount of services and products needed, more or less than the needs of the community, can affect the quality 8,9,11,12,14,17,19. In a study on the status of strategic purchasing in ten European countries, it was found that the amount of information, expertise, policy capacity, and bargaining power was effective in the amount of strategic purchasing. In the studied countries, the emphasis was on the quality of care and the real needs of the community, rather than the use of old patterns, prices, and capacity 6.

In a study conducted in Iran, it was stated that the strategic purchasing of health insurance services helps to utilize the limited resources of the health sector of the country to ensure the health of the Iranian population and achieve the maximum level of efficiency in the health system. In addition, it helps to achieve equity in the distribution of health services, target resources, improve quality of health services, and improve the methods of health service payments 23.

The assessment of the status of quality in different domains of strategic purchasing of health services showed that this issue has not been adequately addressed. Hence, further research is needed to investigate this issue and to motivate health authorities in the community to focus on this topic
