“One can die, but cannot fall ill”– A Survey on how costs may affect choice of therapy in Singapore

An article by Song Chiek Quah of the National Cancer Centre in Singapore



Continued advances in medical care in the recent years have given some hope to patients afflicted with diseases that, in the past, have poor prognoses. However it would seem that hope comes at a price, at least within the Singaporean context. This paper will explicate this issue using the example of patients with Recurrent Head and Neck Squamous Cell Carcinoma deemed inoperable after Radical Radiotherapy and in whom chemotherapy is liable to render poor results

For these patients the advent of two new therapies offers a glimmer of hope. The first of these treatments comes in the form of the addition of cetuximab (Erbitux, Merck), a monoclonal antibody to Epidermal Growth Factor Receptor (EGFR), to standard platinum-based chemotherapy. The results within the EXTREME study revealed an increased median survival by 2.5months.[1] The second arises from Phase II studies in Finland and Japan using Boron Neutron Capture Therapy (BNCT) which have also shown improvement in the median survival in this group of patients.[2,3] BNCT is a form of tumour-selective therapy based on the nuclear fission reaction that occurs when boron-10 is irradiated with low-energy thermal neutrons to yield high linear energy transfer α particles and recoiling lithium-7 nuclei.

Both these new therapies are costly and within a society where heavily subsidized care costs are borne by patients, concerns arise as to whether such interventions may lie outside the reach of many Singaporeans.[4] To be clear, Singapore employs a novel health care system that employs shared health care responsibility. This is to suggest that
on the surface, the government through heavy subsidization of health care costs attempts to share and offset the care costs of a patient whilst entrusting individuals with some responsibility for their own health care needs.[4] This subsidization then represents the first tier of this novel health care system.[4]

The second tier is Medisave, a mandatory medical savings account designated for future medical needs into which employed Singaporeans and their employers contribute monthly.[4] The third is Medishield, a low-cost catastrophic illness insurance scheme designed to help meet medical expenses for major illnesses or long hospital stay. Premiums can be paid from individual Medisave.[4] The last tier is Medifund, an endowment fund set up to assist needy Singaporeans who are unable to pay for their medical expenses, despite subsidies, Medisave and Medishield.[4]

A common perception as a result of such a personalized savings account is that most people view this money, earmarked as it may be, as their own money, thus dipping into their own pocket to cover costs, can be particularly unpalatable to some. This results in a common lament by Singaporeans is that “One may die, but cannot fall ill”, as the latter can incur a substantial financial bill. This study attempts to explore if this perception warrants merit.


Study Population

This study approved by the Singhealth Centralised Institutional Research Board with the reference number 2009/806/B. Invited nurses, radiotherapists, research coordinators and doctors employed atNational Cancer Center,Singapore, participated in this study. This questionnaire study was carried out over a 6 month period from Dec 2009 to May 2010


A 3-page survey was designed (see Figure_1). Participants were invited to complete it in the presence of the author, in order to facilitate discussions around the hypothetical situation in which they had locally recurrent, inoperable, previously irradiated, non-metastatic head and neck cancers. They were then presented with details of three different treatment options, which include the toxicities of the treatment, the treatment duration as well as the known published median survival of the treatment. These treatment options were labelled as:

  • Standard Treatment – Chemotherapy (ST), which is based on six cycles of combination chemotherapy using cisplatin and 5-fluorouracil
  • New Treatment – Combined Chemotherapy and Targeted Therapy (NT), which is based on the successful addition of cetuximab to standard chemotherapy as shown in the EXTREME study.[1] The number of cycles of the targeted therapy was based on the average reported in the EXTREME study
  • Experimental Treatment – Particle Radiation Therapy (ET), based on Boron Neutron Capture Therapy. The treatment details and efficacy were obtained from the published papers by Kankaanranta and Kato.[2,3]

The participants were asked to choose one of the above three treatment options in each of the following three similar scenarios that differed only in the cost of the treatment:

  • In scenario I, the costs presented were based on actual institutional costs, though they did not include the costs of ancillary, palliative and supportive care. For ST, the cost of treatment included the costs for six cycles of cisplatin and 5-flurorouracil combination therapy. Similarly for NT, the average number of cycles of cetuximab, determined from the published results of the EXTREME study. For ET, travel costs, board and lodgings in the vicinity ofHelsinkiUniversityHospitalwas included. Here, the cost of BNCT was established after a correspondence with Boneca Corporation (May 2009), who oversees BNCT therapy inFinland. The toxicity profile and the median survival were obtained from the respective published sources.
  • In scenario II, the cost of NT and ET were both reduced, to simulate the effect of partial sponsorship or subsidy. The cost of ET was reduced to cover the airfares and the hotel stay for the treatment. The cost of NT was reduced to match that of ET.
  • In scenario III, the costs of all three treatments were made to be free, to simulate total sponsorship of therapy.


In essence, the only difference between all three scenarios was the cost of treatment.

In each scenario, the participants were also asked the reason for their choice of therapy. Demographics data was collected.

The author was present throughout when each participant completed the survey, to explain what the survey was about, the details of all three treatments and to clarify any doubts. The exact nature of each treatment such as chemotherapy regime, which targeted agent and what type of particle therapy, was only furnished upon direct enquiry.


139 out of 151 healthcare workers responded to the survey, giving a response rate of 92%. 85% of responders were female and the median age of responders was 31 years old. 40.3% were nurses, 29.5% were radiotherapists, 12.2% were clinical research coordinators and 8.6% were doctors. The remaining 13 responders (9.4%) included dosimetrists, administrator and a physicist. The respondents in all the groups had worked for a median of 7 years.

Figure 2 illustrates the differing proportion of subjects who chose each treatment in each scenario. A chi-squared test of independence was performed to examine the relation between cost of treatment and the proportion of people that chose that treatment. The relationship between these variables were significant, C2 (4, N=139) = 171.15, p < 0.0001. The subjects were more likely to choose new or experimental  treatments if their costs are lower, best exemplified by the findings was that most people (78.4%) chose the cheaper ST in Scenario I while most (80.6%) would chose ET in scenario III.

Cost was the reason majority (91.7%) of people chose ST in Scenario I (Figure 3), while the longer Median Survival was the reason majority (69.6%) of people chose ET in Scenario III. (Figure 4)


This study was designed to elucidate cost considerations in decision making and indeed the only difference between the three scenarios presented were costs considerations. The most striking finding was that as the cost deceased, there was an increase in the proportion of people who viewed median survival rate conferred by the treatment as their main priority. It seems that many participants would forego treatments that can yield a longer survival because of high prohibitive costs; and the increase in the proportion of participants who would consider the newer technologies after their prices were cut in Scenario II and III does appear to reinforce this point.

According to an analysis by global consulting firm Watson Wyatt, “Singaporeis generally acknowledged as having one of the most successful healthcare systems in the world, in terms of both efficiency in financing and the results achieved in community health outcomes.”[5] Despite Singapore’s healthcare’s mixed financing system, with multiple tiers of protection to ensure that no Singaporean is denied access to basic healthcare because of affordability issues, this survey suggests that such a system is not without drawbacks. In fact, this survey reinforces the general notion, as well as numerous anecdotal experiences recounted by healthcare professionals, that some patients would opt for no treatment, rather than to pay the excessive costs associated with today’s treatment. It is vexatious indeed to know that within such a “successful” healthcare system, there are Singaporeans who refuse treatment, for the perverse reason of not being able to afford the price of new treatments.

The findings showed that participants are willing to consider newer treatments but would only pay a fraction of the current price of these new treatments. Can such price reductions be conceivably achieved? The author believes so. In the course of writing this manuscript, the author’s institution had already decreased the cost of cetuximab by 25%. Similarly, the international BNCT community, in tandem with local initiatives, can work together to reduce the travel, accommodation and care costs involved, making BNCT more accessible. In addition, investment should be made into the research and development of accelerator-based neutron sources to provide the low energy neutrons required for the BNCT reactions. These are generally considered to be cheaper and safer than nuclear reactors, which have hitherto been the standard neutron sources for BNCT, making such novel treatments more accessible.

The next logical questions will then be: Should such treatments be made more affordable and thus, more accessible? Opponents of such a move believe that an individual should assume responsibility for their own health, and thus their own healthcare expenditure, rather than reliance on the state. They believe that illnesses are the consequence by unhealthy lifestyles, which could have been avoided in the first place. On the other hand, since millions of dollars have been spent on developing new technologies and conducting trials to show that they benefit patients, it does not seem logical to deprive similar patients, who are not enrolled onto clinical trials, the same state-of-the-art technology, because they cannot afford it. As such, ways should be explored to remove the biggest obstacle to accessing these newer technologies – cost – especially if these new technologies have significant advantages over conventional standard ones, in terms of treatment efficacy and morbidity. There is probably no perfect healthcare financing system that can resolve this argument, but suffice to say, both opposing views warrant merit, just as the Jedi Master Obi-Wan Kenobi pointed out: “Many of the truths we cling to depend greatly on our own point of view.”


The most obvious limitation of this study was the fact that the study population was the healthcare workers in our institution that was not representative of the general population. However, they are themselves subject to the same considerations that most patients have within such settings leaving their responses not altogether incommensurable.

On another point, concerns about the validity of hypothetical scenarios within this setting have also been raised. Yet for the most part such scenarios are regularly utilized within such wide settings as Advanced Care Planning (ACP) and goals of care discussions to great effect.[6] Such discussions involve making healthcare decisions in advance so that a person is not put through treatments that he or she does not want. During these discussions, scenarios representative of the range of prognosis and disabilities are presented. Through such a range of scenarios, it is possible to note when the patient’s preferences change, allowing the physician to identify the patient’s personal preferences and values. In this study, it was through a similar method that identified how people view their lives with respect healthcare costs.


The phrase “One can die, but cannot fall sick” refers to the prevailing notion amongst Singaporean that it is more affordable to withhold treatment and await death than to pay for high healthcare costs. This survey suggests that such a notion may well be a true reflection of the sentiments amongst its participants. It also reminds physicians that costs can play a significant role in a person’s choice of treatment. Until the issue of high healthcare costs is adequately addressed, a plethora of questions have no easy answer. Is Mr X, who declined treatment for his illness doing it out of misplaced altruism? Is Ms Y, who decided to extubate her comatosed father, doing it in the best interest of the latter or to decrease the costs of staying in an intensive care unit?  It is indeed a difficult walk through the minefield of medical ethics and financial burden.  But it is a walk that needs to be taken to avoid a situation where the wealthy “have-lots” have a choice of being treated with the “best there is”, while the impoverished “have-nots” are relegated to just waiting for their meeting with the Grim Reaper.
