1 Background

In countries that are building and expanding their healthcare (HC) systems, pharmaceutical products often represent a considerable part of the total HC expenditure, ranging from 20 to 60% [1, 2]. In addition, most countries with expanding healthcare coverage (CEHCs) are low- and middle-income countries, which still rely significantly on private health expenditure in the form of out-of-pocket payments and voluntary health insurance [3]. However, as many CEHCs strive towards universal HC coverage and to expand the access to HC including pharmaceuticals and decrease out-of-pocket spending, increased expenditure and burden on the public HC budgets can be expected [4, 5]. The payers and purchasers in such countries are under high pressure to develop effective procedures and mechanisms supporting more efficient use of the limited financial means by attaining maximum health benefit at a minimum possible cost. Single-source products are mostly protected through patents with limited options for cost containment through competition. Therefore, cost-containment policies often target off-patent multi-source products. For off-patent pharmaceuticals, tendering is one of the procedures commonly deployed to achieve the lowest possible purchasing price and to have it fixed for the time of the resulting contract.

Tendering can be defined as: “The acquisition of pharmaceuticals based on a competitive bidding process where the contract is granted to the pharmaceutical supplier who offered the best bid following strict criteria” [6, 7]. Tenders for medicines offered by competing suppliers are also conducted in many countries with developed HC systems. While tenders can be powerful in minimizing acquisition costs, they may also expose the HC system to some risks [8]. An important aspect in conducting tenders effectively is the criteria used for selecting a winner. Even, if containing the same active ingredient, there may be important differences between product alternatives relating to, for example, regulatory approval process, data available, formulation, dose, or manufacturer reliability, and manufacturing regulatory and quality standards [9]. If all products in a tender were equal and completely interchangeable, the winner should be the product with the lowest cost.

In many CEHCs, however, there is a high variability in the products offered in tenders. Differences can relate for example to quality, manufacturer reliability or capability to deliver, the formulation, or intended or unintended effects at the patient level. Moreover, when additional costs are incurred when using the product, it is important to take the total cost into consideration. When only focusing on price in the supplier selection, factors related to product value and health outcomes for the patients are neglected. However, most patients are currently treated with off-patent pharmaceuticals and therefore, tendering for off-patent pharmaceuticals must be conducted in a manner that protects these patients against potential negative consequences of the methods used for procuring pharmaceuticals. By ensuring good tender practices, purchasers and decision makers of CEHCs, alongside efficiently using the financial resources, can make an important contribution to the stability and accessibility of the HC services in their country.

2 Objective

This research aims to examine the effectiveness and impact of tendering practices in different HC environments and to make recommendations as to good tender practices for CEHCs based on a literature review of all countries and a survey with current tender experts from one multi-national pharmaceutical company in a number of CEHCs. These can guide policy makers and purchasers in CEHCs on how to make choices that improve accessibility and health outcomes in their country at the lowest possible overall cost.

3 Methods

A systematic review was conducted following the Centre for Reviews and Dissemination guidance for systematic reviews [10] to describe tender practices and to identify, evaluate, and summarize the findings of relevant individual studies regarding tender practices in compliance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statement [11]. Relevant reports published between 1995 and December 2017 were retrieved through electronic searches (performed in August 2017 and January 2018) in PubMed, Google Scholar, and the Cochrane Library databases. The search strategy was based on combinations of two groups of keywords as follows: Group 1: ‘drug’ or ‘pharmaceutical’ or ‘medicine’ or ‘medication’; Group 2: ‘tender(s)’ or ‘tendering’ or ‘bid’ or ‘bidding’ or ‘buy’ or ‘buying’ or ‘purchase’ or ‘purchasing’ or ‘procure’ or ‘procurement’. In further screening, only those publications were retained where the titles and abstracts suggested that they would contain information on the following items: tender system in place (year of introduction, setting); types of procured pharmaceuticals; methodology, frequency, and criteria used and the legal basis for tendering systems. The reference lists of eligible articles were hand searched for further relevant publications meeting the same criteria. Data synthesis involved the collation, extraction, and categorization of the findings of the selected studies included in the systematic review. The publications were categorized and summarized by developed and developing HC systems, the latter generally representing CEHCs.

In parallel, an online survey was conducted to describe current purchasing practices, and more specifically those related to tender practices in CEHCs. The questionnaire [available as Appendix A1 of the Electronic Supplementary Material (ESM)] was completed between March and July 2017 by individual experts in CEHCs such as Algeria, China, Egypt, Indonesia, Lebanon, Malaysia, Pakistan, Philippines, Republic of Korea, Russian Federation, South Africa, Thailand, Turkey, Ukraine, United Arab Emirates, and Vietnam. All responders were market access professionals working in the country affiliates of Abbott (Established Products Division), who are all trained and experienced in purchasing, pricing, and reimbursement mechanisms of off-patent pharmaceuticals. The advantage of sourcing the information from this group of individuals was that it was possible to have a 100% response rate with a level of intra-company semantic consistency. The responses were evaluated and summarized by the research team.

4 Results

The literature search in PubMed and Cochrane resulted in a total of 9546 publications. After the selection of relevant abstracts according to predefined criteria, 14 papers were selected. After hand searching the reference lists of the eligible articles, another 14 publications were added, thus a total of 28 publications were included in the present review.

Tendering for pharmaceutical products is a common practice in many developed countries and, increasingly, also in developing countries. Tender practices have been analyzed and reported in European and other developed countries by academic or institutional researchers, whereby most of these reports comes from European research institutions [7, 12,13,14]. Such work was much less undertaken for the experiences with tender practices in developing countries and, therefore, the description of the tender practices in developing countries was drawn from our survey. The findings for tender practices in both developed and developing countries are summarized subsequently. The first part of this Sect. (4.1) focuses on describing the characteristics of tender systems, while the second part (4.2.) focuses on the impact of tendering in developed or developing countries as reported in the published literature.

4.1 Characteristics of Pharmaceutical Tendering

4.1.1 Developed Healthcare Systems

The approaches for pharmaceutical tendering in developed countries, and especially for Europe, have been reported by several authors and these reports are summarized here. In most of the developed countries, tendering is used primarily in hospital settings and public services (e.g., pandemic plans or military service), but in some countries, tenders are also applied for the purchasing of pharmaceuticals in the ambulatory care sector [7, 12]. Many countries apply the tendering process for a selection of vaccines, pharmaceuticals included in pandemic plans, or pharmaceuticals against communicable diseases.

In general, the tendering methodology depends on the volume of the tender. Tenders are invited from the specific country or from across the European Union. Switzerland is the only country where tenders are limited to pandemic supplies and vaccines for military hospitals. A recent report on tendering concluded that tendering in Europe can contribute to cost containment if embedded in a robust legal and organizational framework with appropriate stakeholder management protecting the users against potential risks [13]. There are European directives, which regulate the use of tenders for public sector procurements in general and specifically, for HC purchasing in Europe [14].

4.1.1.1 Reward Criteria

Lowest price is the prevailing award criterion, but some countries have advanced to select the Most Economically Attractive (Advantageous) Tender (MEAT) [14,15,16]. This is also the approach recommended across all sectors including HC in recent European Union regulations [14]. Criteria such as quality standards or ability to deliver may serve as conditions (i.e., prerequisites) for access to tenders or alternatively, tender selection criteria may include quality, availability, or supply reliability. Tender invitations can be released by single hospitals, regional consortia, or by central governmental organizations. Germany and the Netherlands apply tender-like processes for the selection of preferred providers. In Germany, these are conducted by the health insurance funds on a regional basis. The pharmacists should dispense only drugs from those manufacturers who have been selected as preferred providers by the patient’s health insurer [12, 17].

4.1.1.2 Frequency of Calls for Tenders

Mostly, tenders are conducted in a 1-year cycle, but they may occur less frequent (e.g., 2–3 years in Germany) or on an irregular basis as in the case of Lithuania [7, 13].

4.1.2 Pharmaceutical Tenders in Countries with Expanding Healthcare Coverage

In many countries, tendering systems have only recently been introduced and the introduction is usually not well documented and reported. Therefore, the information for this section was drawn from the survey answered by individuals from Algeria, China, Egypt, Lebanon, Malaysia, Pakistan, Philippines, Republic of Korea, Russian Federation, South Africa, Thailand, Turkey, Ukraine, United Arab Emirates, and Vietnam. The results of these responses are summarized in Tables 1 and 2.

While Pakistan, Lebanon, and the Republic of Korea did not report any use of tender systems for the purchasing of pharmaceuticals, all other responders indicated the use of tendering for pharmaceuticals in some form. In most of the countries, all medicines are purchased through a tendering procedure. In addition, five countries also purchase vaccines through a tendering procedure, and only Vietnam also purchases medical devices through tenders (see Table 1). In most countries, the Ministry of Health and hospitals are the key institutions procuring pharmaceuticals through tenders. Some countries mention military entities or the army (Pakistan, Lebanon, and Algeria). In Egypt and the Russian Federation, tendering can happen throughout all governmental sectors (e.g., Ministry of Health, university hospitals, educational institutions). In Turkey, the Social Security Institution is the single payer; the drugs are sold to the wholesaler first and then, the pharmacies procure drugs from the wholesaler.

4.1.2.1 Reward Criteria

Where tenders are conducted, the lowest price is the key criterion for selecting the winning supplier. Some countries, however, apply additional criteria such as ‘performance’ (not further defined) in Thailand; the ability to supply quantities in South Africa; product categories differentiated by product quality standards as defined in Vietnam [18]; supplier quality and investment by suppliers in Algeria; local manufacturing in Malaysia; or innovation and brand value in some cases in the United Arab Emirates (see Table 2).

4.1.2.2 Frequency of Calls for Tenders

In several countries, calls for tenders are issued annually (Table 2: Vietnam, Thailand, Philippines, Egypt, United Arab Emirates, and Algeria). In other countries, tenders occur every 2–3 years. In Ukraine, many mid-sized and small tenders occur throughout the year, usually in spring and autumn. In Malaysia, tenders are called for products exceeding a budget of US$250 million per hospital. In Egypt and Algeria, the duration of the tender contracts may extend for longer than 1 or 2 years.

4.2 Analysis of Impact of Tender Systems

4.2.1 Tendering Policies in Developed Healthcare Systems

Twenty-one publications relating to the use of tendering in European or other countries with developed HC systems and the key benefits and risks that were reported are extracted into Table 3. Broad experience exists with procurement through tendering in hospitals or for vaccines or pharmaceuticals for the military, but increasingly, tendering is also applied in the ambulant sector [7]. However, there is little ‘European’ agreement on best practices for tendering, each tender system is a ‘homebrew’ by the individual member state institutions [19]. Generally, the focus of the studies is on price management rather than health or other outcomes [20, 21] and too little attention is paid to monitoring the success of the policies [22].

Table 3 Benefits and risks relating to tendering for off-patent pharmaceuticals in Europe and other developed healthcare systems. Summary of the published information
Full size table

Many authors agree that tendering effectively reduces prices and contributes to cost containment in the short term [6,7,8, 13, 17, 20, 21, 23,24,25,26,27,28,29]. This seems to be more evident when there is more competition in the tender [30]. Cost savings were also observed with a tender process used for the selection of preferred providers, such as in Germany [12, 31]. Here, however, it is primarily the insurance companies that benefit [12]. Increased transparency was mentioned as another benefit [7]. In contrast, the long-term impact of procurement through tenders is not yet very well known [12, 29]. There is some evidence that the growth in pharmaceutical expenditure may not be reduced sustainably [25]. Dylst and Simoens reported a phenomenon called “reallocation of demand”, which means that savings are offset by prescribing medicines with a similar therapeutic indication that does not fall under the tendering procedure [32]. In some cases, even increased government budgets were described [8].

Several additional risks and potential negative consequences have been identified. Tendering is challenging for manufacturers and when bidding prices eventually are reduced to marginal costs [17, 23], they will be less motivated to compete and may move away from the business, which may be detrimental for product availability [17, 23, 27]. This will be even more critical for manufacturers of branded products [31]. In particular, tenders selecting only one supplier will lead to monopolist supply situations [24]. Overall, the capacity to produce and supply the products at affordable prices may be reduced [8]. This will lead to decreased competition and consequently, to less pressure to offer the lowest price. Additionally, a reduction in the number of players will make the market more vulnerable for special events and may increase the risk for drug shortages, meaning restricted access to effective medicines for patients [13, 24, 25, 27, 32, 33]. A possible negative impact on HC quality has been red-flagged [8, 24]. Alternatively, manufacturers may choose to cut costs in their production processes, which ultimately may provoke quality compromises [24].

From the administration perspective, procurement through tendering requires a high level of expertise and resources for managing effective tendering processes [7, 26]. The smaller the volumes, the more burdensome and complex are the tenders. Planning and forecasting are demanding, and can be error prone and challenging [7]. It has also been observed that procurement through tendering can lead to an imbalance between foreign and domestic suppliers [26]. Additionally, with decreasing margins, manufacturers will invest less into the growth of the company in this market, which negatively impacts employment and the domestic economy [27, 32]. The reduced investment will be true for both branded and generic manufacturers, and the profitability in pharmacies may also be impacted negatively [27].

A few recommendations resulted from the research and observations in developed HC systems. Among the key success factors of tender programs are a strong legal basis, criteria to grant the tender, the number of winners, and the duration of the tender [6, 13, 28], but also the collaboration of buyers and pooling to achieve larger volumes [26], and the importance of fostering broad competition [30]. Finally, impact assessment is recommended for all pricing and reimbursement policies including tenders [13].

4.2.2 Tender Policies in Countries with Expanding Healthcare Coverage

Research on the impact of procurement by tendering in CEHCs is extremely scarce and only six publications relating to this were retrieved and summarized in Table 4. Often, when such policies are introduced, there is only a limited capacity to establish the processes themselves and only a small amount of interest, time, or ability exists for measuring the consequences.

Table 4 Benefits and risks relating to tendering for off-patent pharmaceuticals in countries with expanding healthcare coverage. Summary of the published information retrieved in the literature review
Full size table

Cost reduction [34] and improved transparency [34, 35] were observed as key benefits. Kaplan et al. recognized the power of competition and the lack of motivation to reduce prices, when competition was low [35]. On the risk side, compromises in quality were emphasized, especially if the legal and structural framework was unable to protect the system [35]. However, setting the appropriate quality standards increased the resulting prices substantially [36].

Finally, there was some evidence that pooling or joint tenders were more effective in attracting bidders and in reducing the prices [34, 37]. Recommendations for the CEHCs included that strict quality standards should be imposed for tender inclusion [38], procurement should be pooled to address larger volumes [39], and a prudent practice for tendering should be followed by CEHCs to achieve their objectives in building their HC systems [38, 40, 41].

5 Discussion and Recommendations

5.1 Process and Prerequisites

Evidence from the literature review suggests that tendering is a well-established tool for purchasing pharmaceuticals or a predictable large volume of products such as vaccines. Especially in CEHCs, tendering is more broadly applied for the acquisition of any HC services in the public sector. In general, tenders seem to be somewhat effective in lowering prices for the purchasers and using public funds more transparently. However, tendering for ambulatory care seems to be relatively new and less evidence is available concerning long-term effects. Tendering procedures require expertise and resources and must be applied to each country’s operational health policy framework. However, the side effects of tendering as summarized in Fig. 1 have also been reported on many occasions.

Risks associated with tender practices as identified in the literature review

Our survey revealed specific behaviors or characteristics of procurement through tenders in CEHCs, which may elevate the risk for the occurrence of undesirable side effects. Such risk factors include the following: (1) products for public HC are procured through tenders without differentiation concerning value characteristics; (2) the lowest price criterion defines the tender winner; (3) tendering systems are applied for the on- and off-patent drug segments; (4) no consideration of the quality of the product or reliability of the manufacturer; (5) high frequency and short duration of tenders; and (6) single winner tenders, as reported from almost all CEHCs. These observations confirm those shortcomings, which had caused the World Health Organization to propose guidelines for pharmaceutical purchasing in low- and middle-income countries [42, 43].

Healthcare policy makers and purchasers are faced with the challenge to create systems, which allow them to maximize in the short term the amount of medicines bought within the frame of limited budgets while also maximizing the value in terms of health outcomes and overall HC costs. Any policy impacts HC for many millions of patients and should be designed to support HC system sustainability. This is of special relevance to CEHCs, which are more susceptible to the risks of flawed polices than countries with more developed HC systems [44]. Transparent and clear tender procedures will help to conduct tenders successfully and the general process is described in Fig. 2.

In the initial PLANNING step, the need for goods or services is identified to develop the procurement plan and budget for the required purchases. This very important preparation phase starts by talking and listening to the users of the product to exactly define the need. It also includes desk research on the market and the inherent risks. Based on this, the scope can comprehensively define the expectations relating to the product and the auxiliary services [45]. Subsequently, the REQUIREMENTS are SPECIFIED through clear and measurable criteria, serving as evaluation criteria as described further below. The criteria may be weighted by importance for achieving the overall goals. The CALL for TENDER will inform potential suppliers about the procurement conduct including a submission checklist and tender specifications. It is useful to develop a standardized approach; in the ESM, we have suggested an example for a checklist for the components (Appendix A2) to be included and characteristics of good specifications (Appendix A3). The incoming bids will be EVALUATED using the predefined criteria in a (weighted) scoring exercise and the CONTRACT will be awarded to the two to three best-scoring suppliers. This step may include additional negotiation of the contract details. Finally, the contracts will have to be MANAGED over the time of the tender contract, which will include inspection of performance and quality, monitoring, and reporting.

5.2 Using Multiple Criteria for the Tender Decision

Most health systems, especially in CEHCs, tend to purchase medical products (including devices, supplies, and equipment) with the primary focus on up-front purchasing costs, not only failing to address patient needs, primarily, but also the needs of providers, health systems, and the society. In contrast to the prioritization of lowest price, there is a universal trend of value-based HC and consequently, value-based procurement: delivering the best possible health outcomes at the lowest possible overall HC cost.

It has often been emphasized that tender evaluation and contractor selection is “one of the most critical undertakings performed by clients, the effectiveness of which is directly related to project success and the achievement of specified objectives” [46]. Making judgments about suppliers and their ability to deliver to the requirements comprises high levels of ambiguity, uncertainty and, sometimes, trade-offs in conflicting objectives. Therefore, criteria supporting the fair and effective assessments of the offers are of eminent importance (e.g., price, experience, capability, quality, performance). Furthermore, the relative importance of the criteria for the selection must be defined [46].

In some developed markets, the MEAT approach makes purchasing processes fit for value-based HC [47]. The MEAT approach integrates, in addition to cost, more criteria for the supplier selection. Tenders are scored on each criterion, and an overall score is computed, to determine the winning tender. Alternatively, the ratio of the score in the criteria over cost is computed. For example, the UK National Health Service clearly define in their ‘Principles of NHS Procurement’ [15] that as the first principle ‘Value for Money’ should be applied in undertaking a procurement exercise and this is determined through the MEAT approach.Footnote 1 The European directive 2014/24/EU suggests in article 67 to select those product(s) with the best price-quality ratio as measured by pre-defined criteria, including cost and outcomes as well as qualitative, environmental and/or social aspects, linked to the subject matter of the public contract in question [14].

Even if the objectives and scope of tenders in developing countries might differ from those in developed countries such as those of the European Union, the risks and potential weaknesses of tendering are the same for any tender process within HC or other industries. In HC in developing countries, however, the users of the products purchased as a result of the tendering process are specifically vulnerable and therefore, should be protected as much as possible against the risks. Our literature review and the survey suggest that clear principles should also guide tenders for pharmaceuticals in CEHCs to foster a sustainable and affordable supply of pharmaceuticals with a minimum risk of unwanted side effects. Tenders for off-patent pharmaceuticals in CEHCs could include criteria such as: (1) costs including acquisition costs and any additional cost that could differ between the alternatives; (2) outcomes documented by evidence (data) on the effectiveness of the product for the target population; (3) other benefits such as patient preferences, application forms, devices, and support services; (4) the broader impact on society in terms of meeting local health policy priorities: local investment, employment, distribution and accessibility, risk management; and (5) quality standards in manufacturing and approval.

Tenders in developing countries often fail to define the prerequisites in the same way as public tenders in the European Union, for example. Therefore, what may be a prerequisite for being able to participate in the tender in the European Union (e.g., Good Manufacturing Practice production or proof of bioequivalence) may sometimes be a criterion for value assessment in a developing country. A range of such potential criteria has been defined in a recent publication by Brixner et al [48].

One option to reduce the complexity of the evaluation is to define narrower tender categories, which confine a fair competition within each of the categories. An example for this was introduced in Vietnam, where five categories of off-patent pharmaceuticals have been defined (see Fig. 3) with a dedicated budget for each category [48]. The competitive evaluation and supplier prioritization occurs within each product category and therefore, the differential value between the categories is recognized and preserved.

A more advanced approach or value-based tender evaluation that can be applied in tenders for off-patent pharmaceuticals in CEHCs is outlined in Fig. 4. Tender specifications and requirements are converted into measurable criteria. Not more than 10–12 criteria should be used. Those criteria more important in the decision (e.g., cost, quality) may be weighted stronger than those of secondary importance (e.g., local employment, added value services). The evaluation of each submission follows a simple multiple criteria decision analysis (MCDA) calculation:

$${\text{Total}}\;{\text{score}} = \left(w_{\text{cost}} \times \cos t + \mathop \sum \limits_{k = 1}^{n} \left( {w_{k} \times c_{k} } \right)\right),$$

where w indicates weight, c indicates criterion rating, k indicates criteria count, and n indicates the total number of criteria. Two examples for such a calculation are shown in Tables 5 and 6.

A case where this approach was applied in Indonesia was described by Inotai et al [49]. Starting from the criteria suggested by Brixner et al. [48] all important stakeholders in the Indonesian medicines tender worked together to define those tender criteria that are relevant in a local context. These authors list criteria related to the product (e.g., proof of bioequivalence, product formulation, stability), the manufacturer (e.g., quality certification level, supply track record, local investment), the services related to the product (e.g., pharmacovigilance, product enhancement services), or the value evidence (e.g., cost effectiveness in the local environment, health outcomes, cost consequences beyond price). Which criteria are appropriate and effective in the setting of a specific country will have to be defined by the stakeholders involved in the specific HC system as shown by Inotai et al. in the example of Indonesia [49], Tuan et al. for Vietnam [44], and by Nurgozhin et al. for Kazakhstan [50]. Other examples for using MCDA in decision making for off-patent medicines in developing countries in a broader sense (price, listing, or formulary decisions) are emerging in several countries such as China, Thailand, or Egypt [48, 51, 52].

As an alternative to calculating an overall performance score from all criteria including acquisition costs, the cost-quality ratio may be calculated and compared:

$${\text{Total}}\;{\text{score}} = \left({\text{Cost}}/\mathop \sum \limits_{k = 1}^{n} \left( {w_{k} \times c_{k} } \right)\right).$$

The cost-quality-ratio approach to tender prioritization has the advantage of linking price and value of products, the latter being defined in ways that are meaningful for the HC policy priorities. It does not discriminate against higher quality products and incentivizes investment in outcomes and quality. Both the resulting total scores and the cost-quality ratios can be compared and used for prioritization of the alternative bids.

Finally, the literature review and survey have resulted in important recommendations (see Table 7) relating to the preparation, conduct, and follow-up of the tender, which should be guiding the establishment of a structured and transparent process. Learning from the current shortcomings of sometimes short-sighted purchasing procedures across the world and designing more robust tender processes will enable CEHCs to further develop their HC offerings while stabilizing the HC systems.

As described by Brixner et al., Inotai et al., and others, a simple multiple criteria process can be introduced by involving the key stakeholders in a country in the adaptation to the local context [9, 48, 49, 53]. Introducing this concept will not only sensitize decision makers to important value aspects of buying off-patent pharmaceuticals but it will also help to increase the transparency and documentation level of decisions in the purchasing process.

In conclusion, tenders can be advantageous if they are well planned, managed, and conducted. This review shows how to consider value criteria in addition to price for the procurement of off-patent pharmaceuticals. In CEHCs, product value categorization, a multiple criteria (weighted) scoring mechanism, or MCDA may be incorporated into the tender for off-patent pharmaceuticals. Important pillars for tender mechanisms that help to ensure sustainability and consistency of supply are: (1) transparency at all stages; (2) an established, accepted, and publicly known process; (3) an audit trail along the entire decision chain; (4) compliance with the country’s and organization’s policy framework; (5) mechanisms such as product value categorization or MCDA to ensure fairness to all parties; (6) the encouragement of competition; (7) written quotations, along with relevant supporting information, against pre-defined requirements; (8) a structure that allows easy comparison of offers; and (9) selection of multiple winners.

6 Limitations

This study is based on a literature review and a survey. Scant research has been performed specifically on tender effects as related to off-patent pharmaceuticals in CEHCs. Therefore, the underlying evidence was drawn from the small amount of research on tender effects in other applications such as hospital tenders or vaccine tenders in developed HC markets. The survey was limited to the viewpoint and experience of one specific company active in the off-patent pharmaceutical sector and may be biased by the respondents’ unique viewpoint. However, great care was taken to avoid such bias and to not guide the respondents in their answers. By suggesting monitoring as a standard part of future tender processes, more evidence should be generated that can be used to refine and improve the overall effectiveness of this purchasing procedure.
