Abstract

A health system is considered efficient when it provides maximum health gains to the population from the available resources. Newer drugs, diagnostics and treatment strategies aim to improve the health of the population, however, they come at an increased cost. Therefore, for an efficient health system, it needs to be decided if the extra cost being incurred is justified to achieve the extra health gains. In this regard, health technology assessment (HTA) helps to make evidence informed decisions by evaluating relative cost and benefits of the available interventions. Economic evidence generated by HTA can also be used in framing standard treatment guidelines (STGs) for high-cost cancer care. In multi-payer systems like India, the decisions regarding the clinical management of patients are taken based on the patients' ability to pay, which creates inequities in utilization of healthcare. Ayushman Bharat Pradhan Mantri Jan Aarogya Yojana (AB PM-JAY) offers an opportunity to ensure equity as it reduces financial barriers, besides having a potential to affect efficiency by including only cost-effective interventions in the benefit package. As a result, informed clinical decisions based upon HTA evidence can make cancer treatment more efficient, equitable and affordable for the patients.

Introduction

The World Health Organization, in its report in 2000, promulgated achieving the best-possible level of societal wellbeing as the overarching goal for all the healthcare systems present worldwide.[1] But, there are several intermediate end points or values that should be achieved first. These intermediate goals include the ability to provide necessary and good quality healthcare services, delivered in a dignified way, at a reasonable cost that does not impose any financial hardship to the patient. To maximize the health benefits to the population with the available resources, the health system needs to be efficient and should ensure that the services are delivered in an equitable fashion to the population.

From the financial standpoint, improving efficiency or the value of money being spent is one of the important ways to enhance the level of population health. There are four key stakeholders involved in the efficient delivery of the health services: the policy makers, purchasers of healthcare services, healthcare providers or clinicians, and finally consumers or patients. Each one of them has a different perception and aspiration for healthcare efficiency. The policy makers ensure that they get the highest value for the money being spent, besides the programs being delivered equitably and that enhance the level of financial risk protection. The purchaser designs health benefit packages (HBPs) of universal coverage schemes, and engages with public and private providers in strategic purchasing. It aims to set prices of the services to be delivered that reflect its value and set the right provider incentives. From the point of view of providers or clinicians, they need to adhere to certain standard treatment guidelines that enhance the level of technical efficiency. For consumers, the value means the overall level of quality of care and satisfaction they achieve with the delivery of healthcare services.

Health Technology Assessment (HTA) aims to evaluate the relative costs and benefits of any new drug, device, and treatment or delivery strategy.

These were considered in terms of their clinical effectiveness, cost-effectiveness, and issues related to ethics, acceptability, and equity.[2] One of the key outcomes of an HTA study is estimating the incremental cost per unit gain in health benefits with application of the new intervention.[3] [4] This needs to be weighed against a value-judgment of whether the extra cost being incurred to produce an extra health benefit is worth spending.

In this paper, we focus on the role of HTA for determining treatment choices from a clinician's perspective. In particular, we focus on the field of oncology that involves decisions for new costly drugs, diagnostics, and treatment strategies. In the next section, we describe how HTA and economic evidence can be used to influence decisions with respect to standard treatment guidelines. We use examples of recent HTA studies to illustrate this point. Next, we describe the health financing situation of India, to highlight the difficulty of integrating HTA evidence for standard treatment guidelines, clinical decision-making, and reimbursement decisions. We finally conclude by describing the future prospects on how informed clinical decisions based upon HTA evidence can make cancer treatment more efficient and affordable to the patient.

Clinical Context

Oncology is the only specialty within the medical field that has had the most number of progressive scientific developments. This leads to generation of new evidences for better ways of practice every day.[5] The new evidence aims at providing better disease-free survival (DFS) and overall survival (OS) rates when compared with the available standard of care. Various international and national guidelines continue to be updated as per the evidence from current state of the art clinical trials, so that all patients can be offered preventive strategies, diagnostic workup, treatment, and supportive care. This will hopefully lead to best-possible health outcomes.[6] [7] [8] These guidelines for the management of oncology patients give evidence-based recommendations based on the disease stage, histology, investigative workup, clinical parameters, performance status, and adverse effects. The guidelines are classified into various categories based on the level of evidence. For example, category 1 is described in the most commonly used. National Comprehensive Cancer Network (NCCN) guidelines refer to recommendations generated based upon high level of evidence with uniform NCCN consensus that the intervention is appropriate.[6] The preferred interventions are usually based on superior efficacy and safety. But, the factors such as cost and cost-effectiveness are not considered here.

Recently, however, the guidelines being prepared by the Indian National Cancer Grid do attempt to stratify the advice based on resource availability in terms of essential resources, desired resources, and what could be done if there is no resource constraint.[8] However, these guidelines also do not explicitly use evidences proving cost-effectiveness. Further, all these guidelines provide multiple preferred options for the same set of clinical situations, and just one preferred option is not separately considered. The choice from among these clinical options is based on the informed decisions taken by the patients. Next, we use examples from three economic evaluations to illustrate how the guidelines could be informed using such evidence.

Breast cancer is the most common cancer among females in India.[9] The adjuvant trastuzumab is an essential component in the treatment of human epidermal growth factor receptor 2 (HER2) positive breast cancer cases. All international guidelines continue to recommend 1 year of adjuvant trastuzumab for HER2 positive breast cancer patients along with chemotherapy.[10] [11] However, a shorter dose duration of the drug for 9 weeks or 6 months has also shown to be efficacious in this scenario. In a meta-analysis performed in India, the 5-year DFS rate with 9 weeks of trastuzumab was reported to be 85.42% versus 87.12% with 1 year of drug use.[12] Similarly, the OS rate was 92.39% and 93.46% with 9 weeks and 1 year of trastuzumab, respectively. While guidelines continue to recommend 1 year of trastuzumab, only 8% of the patients who are candidates for trastuzumab receive it due to its cost.[13] Among this set of patients who use trastuzumab, 50% of them are enrolled in some form of clinical trials and receive the drug for free. So practically, only 40% of the eligible patients are able to afford this expensive molecule for treatment.[14] This clearly shows that cost constraints determine access to treatment, and those who need treatment are not able to receive care, which is likely to lower the health benefits. This clearly indicates inefficient allocation of resources.

In a recent economic evaluation, 1 year of trastuzumab use was reported to result in a gain of 1.29 quality-adjusted life years (QALYs) at an additional cost of 178,877 (US$2,558) per QALY gained.[15] Overall, there was only 4% probability for 1 year of trastuzumab to be cost-effective. The study concluded that 9 weeks and 6 months of therapy is cost-effective in India. Though 1 year of trastuzumab gives greater health benefits, the incremental cost incurred with 1 year of trastuzumab is not justified given the threshold for cost-effectiveness in India. However, if the cost of trastuzumab is brought down to one-third of its current cost by means of price regulation, then there is 80% probability that 1 year of trastuzumab becomes cost-effective in India. The guidance for use of trastuzumab should accordingly be revised in clinical guidelines for India.

Another study was performed to estimate the cost-effectiveness of sorafenib versus best supportive care in patients with advanced unresectable hepatocellular carcinoma with extrahepatic spread, vascular invasion, or progression after local therapies. It was found out that sorafenib incurs 507,520 ($7,861) per QALY gained.[16] The study concluded that sorafenib is not cost-effective for use in advanced hepatocellular carcinoma treatment in India. In a third recent study, use of the adjuvant temozolomide along with radiation therapy for treatment of glioblastoma multiforme was not found to be cost-effective.[17]

We see from the above examples that clinical guidelines based on effectiveness data may not be in-sync with economic evidence. Clinical guidelines continue to recommend dosage of 1 year of trastuzumab, sorafenib, as well as temozolomide.[15] [16] [17] Integration of this with economic evidence specific to India in the clinical recommendations will help to attain greater health benefits at a population level. This will only be possible by optimal utilization of the limited resources. Each of these economic evaluations also indicates reasonable prices for these drugs. This is possible only if these prices are reduced through some regulation or bulk purchasing.

Financing Context: Unearthing the Real Issue

The National Health Service (NHS) in the United Kingdom has a single payer system and is the largest purchaser of healthcare. It pays for the health care of the entire population.[18] It also provides final management guidelines, based on cost-effectiveness evidence that is generated by the National Institute for Health and Care Excellence.[19] NHS can also exert its monopsonistic power to negotiate prices with the pharmaceutical companies, as has been evident in the case of trastuzumab.[20]

India, on the other hand, has a multipayer system. While 14% of the rural population and 19% of the urban population has some form of health insurance coverage, the majority (93% of rural and 47% of urban population) of this insured population is covered under the tax-funded Ayushman Bharat Pradhan Mantri Jan Aarogya Yojana (AB PM-JAY) and other State-funded health insurance schemes.[21] Most of these schemes include treatment of cancer in the HBP too. However, nearly 72% of the total health expenditure in India is incurred by households.[22]

In such a situation, the decisions about the clinical management of the patients are taken based on a mutual discussion between the clinician and the patient.[22] Here, the clinician discusses the various available treatment options with the patient in terms of the risk–benefit ratio. Benefits are described in terms of the rates of OS and DFS. Risks that can be incurred in terms of the adverse effects associated with these treatment options are also explained. Then, the clinician discusses with the patient the cost incurred with each of these treatment options. Based upon the ability of the patient to pay, the choice of treatment is made. Since the government payer or AB PM-JAY does not yield large market share, it is limited in terms of its power to influence clinical decisions or adherence to standard treatment guidelines.

Thus, we see that a strong driver for clinical decision-making in this multipayer system is the patient's ability to pay. This fallout of our health financing situation, where access to care is contingent upon ability to pay, leads to reduced access and unmet needs for those who require treatment. As a result, it is inefficient. Moreover, the poor patients are the hardest hit.[23] [24] [25] This creates inequities in utilization and supply of health care.

Solution

To ensure the application of HTA for value-based healthcare, India would need to move toward a single payer or a single purchaser system, which will purchase healthcare on behalf of the entire population. Hence, it will be able to exercise some degree of control and regulation in India. Currently, the predominant option is the AB PM-JAY. There are three ways in which the AB PM-JAY can influence uptake of HTA evidence in clinical decision-making. First, the HBPs should be determined based on the HTA evidence. Only those treatments that are found to be cost-effective should be included in the standard treatment workflow for reimbursement. Second, the provider payment rates that are set for each HBP should be based on the cost of services that are found to be value-based. Finally, when the providers are reimbursed, there should be incentives (such as higher rating of these empaneled hospitals, or higher price reward) for providers to adhere to these standard treatment guidelines, which should be driven by evidence. This would have twin benefits. First, it would lead to a culture of evidence-based practice that would be efficient. Second, it would reduce the incidents regarding the practice of “balance-billing” to patients.[26] In the absence of such regulation or incentive for adherence to standard guidelines, the clinicians may have a perverse incentive to provide unnecessary care, and charge the same to patients, over and above the claim submitted to AB PM-JAY.

Realization of this utopian, but realistic situation would need to be supplemented with appropriate nudging through a policy environment that supports the uptake of HTA evidence. The global experience suggests that the uptake of HTA evidence is favored by appropriate legislative mandate. Several European countries make the decisions for reimbursement legally binding on HTA evidence. Closer home, several South Asian countries such as Philippines, Indonesia, Malaysia, Singapore, and Vietnam have either a legislative mandate or other legal provisions or by-laws that mandate the use of HTA for a certain category of drugs, thereby providing more teeth to their respective country HTA bodies.

India also created its HTA body in 2018—The Health Technology Assessment in India (HTAIn)—the Secretariat for which is located in the Department of Health Research.[27] [28] Several HTA studies, commissioned by the HTAIn, have led to uptake in policy decisions.[29] [30] [31] A study that evaluates the value-based prices for several anticancer drugs in India is currently in progress. There needs to be institutional mechanisms for a greater interaction between the HTAIn and the AB PM-JAY to enable uptake of HTA evidence. To begin with, any new package added or new drug or treatment to be reimbursed should be subjected to HTA.

A draft legislation—“The HTA Bill”—has been created, which is being considered to be tabled in the Indian Parliament. In its current form, the HTA Bill offers recommendatory status, without any statutory powers. A way forward would be to position the linkage between cost-effectiveness threshold (CET) and the right to health. First, the CET in India should be determined, and then it should serve as a binding rule for the Government to provide proven and cost-effective services.[3] Second, the Central Government's allocations to the State Government, as a part of schemes such as National Health Mission, could be made contingent on the State adhering to this condition of providing proven cost-effective services. So, this has a broader aspirational objective to use HTA to nudge the Government toward universal health coverage and providing the right to health to the patients.

The second legislative issue concerns the pricing of pharmaceuticals. The Government has two ways of regulating the drug prices: inclusion of the drugs in the essential drug list (EDL) or regulating the trade margin. If a drug is included in the EDL, then the Government can regulate its price (Government proposes a price control order formula). An alternative viewpoint could be an application of HTA to determine a “value-based price.” Third, as part of the State-level medical service corporations, the use of HTA should become mandatory for procurement of drugs and devices under these medical service corporations (to identify what should be procured, and at what price).

There are several other criteria and processes that can be used for priority setting.[32] [33] These methods include Multicriteria Decision Analysis, Program Budgeting and Marginal Analysis. However, considering that the systems for HTA have been institutionalized in India, and its capacity is being developed, it is more pragmatic to further build upon the work that has been already done.

Conclusion

Overall, the application of HTA has benefits of making health services, especially related to oncology practice, efficient, affordable, and equitable. The problem lies with the Indian health financing situation, which leads to multipayer system where decision to use health service is contingent upon the payment capabilities of the patient. Investing adequately in health to create a single large purchaser would be the first step.[34] [35] Second, decisions of the AB PM-JAY would need to be linked with HTA evidence. Conducive legislative measures to promote HTA would go a long way in realization of the aspirations of universal coverage and efficient health system for Indian patients.
