Social Health Insurance in Zambia: Getting the bolt and nut right with Health Economics

According to the WHO, Universal Health Coverage (UHC) means everyone in the country can use the promotive, preventive, rehabilitative and palliative health services they need of sufficient quality to be effective, while being protected from financial loss (WHO, 2017). So far, only 58 countries in the world- 10 in Africa are regarded to provide Universal health care as they have legislation mandating Universal Health care. The question is, is this attainable in Zambia? As optimistic citizens, the answer is a resounding “YES”.

However, in the real world, this is just an aspiration of where mankind would love to be-Utopia. Should a Man in need of Sildenafil, Viagra (the conventional Congo dust or mutototo) for his erectile dysfunction get his fair share of the health service as a new-born that needs Measles vaccination? Should a woman that needs breast implants get a fair share as an accident victim that that needs a hip replacement? These questions seem to be clear cut but imagine a choice between providing Second line HIV treatment versus providing palliative care to a cancer patient. As long as resources are scarce, choices will have to be made on resource allocation. Unlike accounting, aimed at balancing the books, of where the money came from and where it is spent, it is important to keep in mind the opportunity cost of these resource allocations. This means that when resources are used in one way, they are not available for use in other activities and the benefits that would have resulted from the left alternative are sacrificed.

Among the critical issues in Social Health Insurance is defining the benefits packages. This gives the insured persons the right to a given set of services in exchange for their contribution. Therefore, a contractual arrangement between the insurance and the insured persons which guarantees a minimum package exists. This is unlike in the tax financed system which only guarantees care to the extent it can afford at a time. Where a clear benefit package is not established, the economic and financial viability of the system remains at risk of failure. In addition, measure to curb gaming of the system (Moral hazard) need to be established from the onset.

Since 1991, Zambia has been looking at introducing social health insurance. In light of the 1991 economic structural adjustment policy, Zambia sought to mobilize additional financial resources for health and thus requested had requested the International Labor office (ILO) to provide health with consultancy services. Fast forward to 2011, the current government rekindled the momentum to introduce Social health Insurance in Zambia. Zambia should be commended for laying a foundation for sustainable health care financing. Nonetheless, the case of Ministry of Health (MoH), who to this day is in charge of health care provision, has been spear-heading the Social health Insurance. One would, argue that MoH becomes the judge and the jury (i.e. Payer and the Provider). This is a big recipe for compromised service provision as it tends to create what may be some sort of a “bilateral Monopoly”, market of one supplier and one buyer-except the buyer and seller in the case of the Ministry of Health in Zambia is one. This does not favor competition and ultimately kills quality improvement. Therefore, I order to ensure that the dream.

With the need to provide care for all one would argue about what kind of medical technologies to pay for and what not to pay for. With the technological advancement, arrays of treatments for diseases have been established. Some treatments may provide superior clinical effectiveness alas at a high cost. The question, which arises then, is whether the extra clinical benefit is worth the extra cost. It is such questions that have lead to the establishment of Pricing and Reimbursement sections in Health Insurance, Schemes such as the Pharmaceutical Benefit Scheme of Australia, and the National Institute for Health and Care Excellence (NICE) in the UK, the National Center of Pharmacoeconomics in Ireland etc. The hallmark of these institutions is to see to it that a Budget Impact Analysis (BIA) and an Economic Evaluation is conducted whenever there is plans to introduce a new treatment or even change the treatment guidelines. For example, when switching to option B+ in HIV management in Zambia, as advocated for by the WHO, it is also argued that local health economic evaluation is necessary to understand the cost implication.

As is always the case in Economics, one can always learn from history or experiences of others. Therefore, as Zambia embarks on the Social Health Insurance program, it can learn from other countries. For Instance, Germany known to be among the oldest Social Health Insurance countries, introduced health Economics evaluation to improve efficiency and curb the deficit that was increasing. Similarly, South Korea, which introduced Social Health Insurance in 1977, much like the intended Zambian model that aims to first start with employees in the formal sector was faced with a cumulative deficit. This led to a number of reforms among them was the use of Economic data in decisions regarding payment for newly introduced medical technologies. Therefore, it just makes sense that from the very beginning Zambia incorporates Economic Evaluation in the reimbursement for Health Technologies under the Social Health Insurance.

Therefore, as Zambia forges ahead with Social Health Insurance, it is time to ensure that the foundation is well set and that strong institutions that consider not only how resources are mobilized in the health sector but also that the citizens get value for money. One such arm of this institution would be a strong Health Technology Assessment wing. This wing should be mandated to deliver evidence based recommendations on health technologies. The wing should create a multi-disciplinary pool of experts in Health Economics, Clinical practice, public health, laboratory services etc. Then and only then will we see this institution serve its purpose.
