Abstract

Objectives To identify priority medicines policy issues for New Zealand.

Setting Stakeholders from a broad range of healthcare and policy institutions including primary, secondary and tertiary care.

Participants Exploratory, semistructured interviews were conducted with 20 stakeholders throughout New Zealand.

Primary and secondary outcome measures The interviews were digitally recorded, transcribed and coded into INVIVO 10, then compared and grouped for similarity of theme. Perceptions, experiences and opinions regarding New Zealand's medicines policy issues were recorded.

Results A large proportion of stakeholders appeared to be unaware of New Zealand's (NZ) medicines policy. In general, the policy was considered to offer consistency to guide decision-making. In the context of Pharmaceutical Management Agency's (PHARMAC's) fixed budget for procuring and subsidising medicines, there was reasonable satisfaction with the range of medicines available—rare disorder medicines being the clear exception. Concerns raised were by whom and how decisions are made and whether desired health outcomes are being measured. Other concerns included inconsistencies in evidence and across health technologies. Despite attempts to improve the situation, lower socioeconomic groups (including rural residents) Māori and Pacific ethnicities and people with rare disorders face challenges with regards to accessing medicines. Other barriers include, convenience to and affordability of prescribers and the increase of prescription fees from NZ$3 to NZ$5. Concerns related to the PHARMAC of New Zealand included: a constraining budget; non-transparency of in-house analysis; lack of consistency in recommendations between the Pharmacology and Therapeutics Advisory Committee. Constraints and inefficiencies also exist in the submission process to access high-cost medicines.

Conclusions The results suggest reasonable satisfaction with the availability of subsidised medicines. However, some of the major challenges include access to medicines in vulnerable groups, increasing costs and demand for new medicines, access to prescribers, budgetary constraints, cultural and health literacy, patient affordability and evidence requirement for gaining subsidy for medicines.

Strengths and limitations of this study

  • This study is the first independent objective study to identify priority medicines policy issues, from a broad range of stakeholders.

  • Has identified access to medicine issues requiring further research.

  • Provides a context to identify issues.

  • The views expressed are from 20 stakeholders. Issues raised in this research project are therefore indicative.

Introduction

New Zealand has a population of approximately 4.5 million, with a nominal gross domestic product of approximately NZ$211 billion.1 New Zealanders have an average life expectancy of 81.2 years, which is above the Organisation for Economic Co-operation and Development (OECD) countries’ average of 80.1 years.2 Just under 83% (82.7%) of health expenditure in New Zealand is publicly funded.3 New Zealand's health and disability budget at the starting of this research is NZ$13.983 billion.3 In comparison with other OECD countries, as a percentage of total expenditure on health, New Zealand spends less on pharmaceuticals.2 Approximately NZ$795 million and NZ$280 million are available for procuring community/cancer and hospital pharmaceuticals, respectively.4 This compares with a reported estimated spend of NZ$880 million on medical devices.5 Approximately 1848 medicines are subsidised by Pharmaceutical Management Agency (PHARMAC, as listed on its Pharmaceutical Schedule) for use in the community and are largely accessible via prescription from a medical doctor.6

Medicines and New Zealand

Medicines make a significant contribution to health outcomes.7 In 2007, ‘Medicines New Zealand’ New Zealand's medicines policy, was launched in response to access concerns from the public.7 The aim of the policy is to promote quality, effective and optimally used medicines. To guide decisions, principles of affordability, equity and need are stated.7 Medicines New Zealand aims to ensure that the decisions made about prioritisation and funding are as transparent as possible, understood and open to debate. It is important for New Zealanders to have confidence that the medicines system is fair, even if they do not always agree with the decisions made.7

Pharmaceutical Management Agency

PHARMAC, established in 1993 in response to increasing expenditure on pharmaceuticals, is a separate non-profit government agency whose role is to determine and procure community and oncology medicines on behalf of New Zealand's 20 District Health Boards (DHBs). PHARMAC has a predetermined fixed budget which it is required to operate within. In order to provide medicines considered necessary, PHARMAC employs therapeutic and economic analyses to guide decisions. PHARMAC's scope is now expanding to include hospital medicines and some medical devices.

For the majority of patients prescribed a medicine listed on PHARMAC's schedule, a NZ$5 DHB charge is incurred. For high user or low socioeconomic patients, access enablers (eg, Prescription Subsidy, Community Services and High User cards and, recently, the Services to Improve Access (SIA)) exist to help ease the financial burden.6

Literature exists indicating medicine issues for New Zealand related to: inequities in access, affordability, processes used and their funding.8–31 However, no systematic work has been conducted to identify priority medicines policy issues with regard to access and funding of medicines. Within this context, it was considered timely and appropriate to conduct research that could identify priority medicines policy issues for New Zealand.

The dataset obtained from this research was expected to be substantial and provide a solid platform to contribute towards informing medicines policy, expenditure and provision, and the development of optimal medicines management strategies.

Aim

The aim of this project was to identify priority medicines policy issues for New Zealand.

Methods

Study design and participant selection

We conducted a general inductive study using semistructured exploratory interviews during December 2012–March 2013. Selection was purposeful to ensure a broad representation of stakeholders and their opinions, who had one or more of the following traits in relation to medicines policy: involvement in its formation or implementation had researched and/or commented on medicines policy, including having made submissions during its development (n=10); medically qualified doctor (n=7, four of whom were active prescribers, including one of each of Māori, Indian and Asian ethnicity); medicines regulation (n=1); representation of or past or current involvement in medicines supply, procurement, funding or provision (excluding dispensing, n=6); involved in medicines management (n=9, one of whom was of Māori ethnicity); medical information or health technology assessment interest (n=2); medical interest group representative (includes ethnic medical group/association, past or present, n=4); private health provision and subsidy (n=1); patient group representative (PGR; n=2, one of whom represents and advocates for a large chronic disease group, disproportionately represented by Māori, Pacifica and increasingly Indian and Asian ethnicity). Participants’ characteristics are summarised in table 1.

Stakeholder characteristics: stakeholders n = 20

A total of 26 stakeholders were contacted and explained the research involvement. Twenty stakeholders consented and were interviewed. All 20 received a ‘Participants Information’ letter detailing the involvement, aim and general methods. All signed a confidentiality and anonymity agreement. Fifteen interviews were conducted face to face and five via telephone, due to geographical or time constraints. The average length of the interview ranged from 53 to 56 min. No gratuity was offered.

Instrument development

The main aim of this research was to identify priority medicines policy areas. An in-depth literature review was conducted to ascertain existing information on pharmaceutical policy. A total of 105 references were identified as useful. The following broad themes were discovered and, accordingly, sets of questions developed: (1) medicines policy: including participant's awareness, description and opinions; (2) ethnicity inequities in accessing medicines (eg, Māori, Pacifica and recently immigrated people whose first language was not English); (3) PHARMAC: its pricing policy, impact on access, economic modelling, performance, future and any improvements; (4) the Trans Pacific Partnership Agreement (TPPA): impact on access and resultant considerations; (5) high-cost medicines access; and (6) medicines policy issues not covered but considered important (see online supplementary appendix one for question details).

The questions were piloted by one doctor of Māori ethnicity and one pharmacist (Ph) with an interest in medicines policy, medicines management and academia, who had previous experience in the pharmaceutical industry. Their responses were not included for analysis.

Data collection

Participants (stakeholders) were encouraged to give comprehensive answers. Clarifying and confirming questions were asked where more information was considered necessary, or to avoid interviewer assumption.

All interviews were recorded on a voice recorder, and transcribed intelligently (space fillers were omitted to enable ease of reading). Participants received their own transcript to proof, edit and approve. Only the approved editions were entered into INVIVO 10 (QSR International Pty Ltd) for coding.

Coding was conducted two ways: first, categorically according to answers and second, highlighted, grouped and compared according to similarity of theme. Transcripts were checked for any missed issues.

A check for stakeholder bias was conducted using the coding summaries, but no apparent bias was detected. Any variations appeared to be attributable to stakeholder knowledge.

Results

Issues revealed specific to ethnicity, PHARMAC, the TPPA or high-cost medicines are reported in those sections. A summary of issues is available in table 2.

Table 2

Summary of issues

General medicines policy issues

Nine participants stated they were unfamiliar with the policy. However, four demonstrated a tacit understanding. It was questioned how policy intentions and decisions are made, in the context of being achievable: How do you attain that?...what is the right way to make those overall policy decisions… (pharmaceutical industry stakeholder, PI)

All participants believed medicines make a positive contribution to health. Differing levels of impact on health were noted. There was uncertainty as to how the impact is or could be quantified. The lost opportunity from not capturing and accessing data efficiently was voiced by two academics for treatment and outcomes monitoring: …we are not asking questions about patient health status before and after…so you can really see what is going on, at the GP level. Because that's at least as important as hospitalisation data (Academic, Ac)

Conversely, one participant said he would prefer to see more investment in epidemiology, as opposed to increasing the medicines budget, in a desire to preserve health.

Low socioeconomic patients were considered to have a higher burden of disease. Affordability to prescribers was described as the major issue, which may be compounded by the 2013 raise in prescription copayment from NZ$3 to NZ$5.

Despite access enablers, such as the High User Cards and Community Services Cards, it was questioned whether those in need are utilising them. One general practitioner (GP) said cost-sensitive patients could be managed with prudent prescribing and education on priorities: You could get all your medicines for less than a pack of cigarettes. It's educational priorities and various other things, where the effort needs to go rather than reducing the cost much further (GP)

The opposite situation of the misuse of access was described: I initially struggled to understand how somebody could pull up outside a pharmacy in a Mercedes Benz and…present their scripts for their family and handover their Community Services Card…As soon as they get in the country; they put the money into a family trust…So the wealth of the individual gets assessed, which qualifies them for a Community Services Card and then they wave that around (Pharmacist, Ph)

Sole supplyi provision raised issues in terms of: supply outages when switching supplier (and having to pay for the alternative option) options for patient intolerance and vulnerability if a significant disruption in supply occurs (eg, a disaster destroying a supplier's warehouse).

There was an additional reference to policies and funding needing to be consistent and interlinked, especially for priority areas. ‘Quit-Line’ was given as an example: a NZ$40 million funded smoking cessation programme, described as having markedly less evidence than the appropriate medicines (which were not funded for many years). Budgetary constraints were the reason given for this. Equally, the government funding of ‘alternative medicines’ was described as something which needed a debate: …government is providing funding for people to obtain alternative medicines…real debate to be had…money better spent some place else in the healthcare system? (Pharmceutical Industry, PI)

One doctor voiced frustration at PHARMAC's Pharmacology and Therapeutics Advisory Committee (PTAC)ii being ‘generalists’ who override the recommendation of their subcommittee. With patient subtyping and genomic medicine on the horizon, he considered that ‘generalists’ may not understand what they are assessing and dismiss research, thereby inhibiting access. Access is then through an ability to pay for litigation and decided by a non-medical expert.

With demographic changes increasing the demand for healthcare services and a general movement towards increasing costs of new medicines, there was concern for future affordability of medicines. It was suggested that funding may move away from being population based and move towards funding health outcomes. An academic suggested that changes in copayments, taxation or medicines classification status may result. The oncologist had concerns that the lack of research (research being an attracter) being conducted within New Zealand will compound the low availability of future medical specialist prescribers. Extending prescribing ability to non-doctors was considered a help. However, for oncology, a medical specialist was still considered to be required to make treatment decisions.

Ethnicity issues

Most of the issues presented related to socioeconomic variables and are presented under General Medicines Policy Issues.

Those with poor English speaking skills were described as having access to an English speaking relative or even interpreters if needed: I think if they can access General Practice or the Hospital system, their access to the medications is just as good as anybody else's. I'm not aware of any specific ethnic problems in accessing our medicines… (GP)

One GP felt strongly that Māori and Pacifica access inequities are evident and are resulting in poorer health outcomes. He believes his colleagues are treating everyone the same but with inequitable risk: earlier intervention, improved communication, education and patient engagement are required: I think the key issue is the prescribers have a poor understanding of inequalities. Because, the prescribers generally approach things as; I treat everyone the same…they must have an inequity lens on anyone they see…but if the quality of your discussion and the quality in the way in which you prescribed that was poor i.e., you culturally are incompetent and you have a disconnect with the patient… (GP)

Other issues related to Asian ethnicities wanting treatment (oncology setting) irrespective of the likely outcomes and the use of alternative treatments, for example, St John's Wort or vitamin C injections impacting on medical treatment. One of the doctors had issues with alternative practitioners recommending such treatments.

Pharmaceutical Management Agency

There was general appreciation shown towards PHARMAC's strategy of creating competition in order to achieve a lower purchasing price. This was seen as advantageous for the purchase of a greater range of medicines, in the context of a fixed budget.

The budget was defined as the threshold for provision, which was considered too small by an academic and pharmaceutical industry stakeholder, causing a focus on cost as the driver of value and provision, thereby contributing towards ‘static efficiency’: If Pharmac's objective is to stay within budget then it's doing well…improve the health of New Zealanders within a capped pharmaceuticals budget…it's doing moderately well…objective were to improve the health of New Zealanders taking into account the financial constraints of Vote Health…it's doing poorly because it should be fighting for a better share of Vote Health (Ac)

A public service (PS) stakeholder offered the following standpoint: ‘You can always achieve more with more’ (in terms of a bigger budget), but an analytical framework is not in place that would define whether the medicines budget receives a fair proportion of ‘Vote Health’ or not.

PHARMAC's budget is determined at regularly defined intervals but medicines enter the marketplace sporadically. This has resulted in concerns from oncologists who believe that extra funding may not be available to cater the needs of patients.

The Private Health Care Organisation (PHCO) stakeholder thought PHARMAC's approach of requiring new and more expensive medicines to be better than standard medicines a ‘completely acceptable approach’. It was suggested by the PHCO and an academic that their approach could be more widely adopted, both overseas and with the expansion of PHARMAC's role to medical devices: …the expertise PHARMAC has built up…is something that we could learn from and borrow from, for the wider health sector…I'd like to see them take on medical devices, because that is absolutely scandalous that these products are getting onto the market without being properly evaluated… (Ac)

There was caution given by one pharmacist that PHARMAC's expansion into hospital medicines (in an acute care setting of moribund disease) may limit choices. Concern was shown for risk, if New Zealand is leading the world in this type of provision.

Provision was described as having a utilitarian focus: ‘The greatest good for the greatest number’ (PS) and described as being: you get what you need—not what you want. One doctor questioned whether the lost opportunity from not treating someone is being measured. Rare disorder patients were mentioned and are discussed under High Cost Medicines. The distinction was made that provision of a medicine in a cost-effective manner, which PHARMAC achieves, is not the same as delivering healthcare: I find some of their PR a little bit irritating…bray on about the marvellous healthcare they're delivering…delivering medicines in a cost effective manner but that's not saying it's delivering healthcare… (PHCO)

Questioning PHARMAC's undertaking of economic modelling received very favourable comments from 15 of the participants. Three participants were not familiar with economic modelling: I think it's world leading actually. No one else dares do it. That's the crazy thing. Here we are little old New Zealand and we dare do it (Ac) Well I mean, as a tax payer you could argue that for the majority of the products they get in, they've done a really good job of driving cost out of the system (PI) Technically it's very good. PHARMAC considers clinical effectiveness and cost effectiveness…they make trade-offs…they look at the QALYs and the number of people affected and how their quality of life will be improved and so on, I think is a very good model (PS)

It was suggested that the cost–benefit of returning an individual to their normal daily activities should be considered by PHARMAC, such as what Accident Compensation Corporation does when assessing intervention options.

A pharmaceutical industry stakeholder and academic were concerned that the required economic modelling submitted by suppliers is adjusted with unknown ‘in-house’ variables, making it hard for suppliers to understand decisions. This was contrasted against Medsafe's practice, where decision modelling is transparent: Pharmac receives a dossier from the company…Assumptions of statistical models get changed…QALYs get changed…population who will use the product get changed…that should be part of a scientific debate…companies don't know what information is being used to make the decisions on their products…we would like a right of reply to those…It happens with MedSafe…Not as though it could potentially negatively affect evidence based decisions (PI)

Delays in the submission process of up to 8 years, described as a ‘medicines waiting list’, were a matter of concern for an academic, pharmaceutical industry stakeholder and PGR, all of whom thought access was related to cost. There was a suggestion from one academic to follow Australia's submission process and outsource assessments from independent bodies.

Trans Pacific Partnership Agreement

Very few participants were familiar with the TPPA, which some referred to as speculation and no facts. One participant refused to make any comments related to the TPPA.

There was acknowledgement that trade deals are complex and often require compromises and trade-offs. New Zealand was referred to as a ‘small country’ and ‘we need our trade partners’. There was concern that already ‘big amounts’ are being spent on healthcare and the ‘benefits are low’ and if there is a resultant increase in the cost of medicines, where would resources come from to offset any cost increases.

The main issues were: (1) patent extension, delaying generic entry into the market, thereby prolonging a higher cost of provision; (2) industry influencing supply (described as an issue of sovereignty) may result not only in quicker access to new medicines, but also in an increase in public campaigns and appeal processes if PHARMAC's decisions are unpopular with the pharmaceutical industry or patient groups; and (3) transparency requests in PHARMAC's assessment process caused the most concern and confusion. One academic said he did not think PHARMAC could be more transparent and that transparency might mean the industry discloses its pricing processes and the results of all clinical trials.

In general, scepticism was voiced as to what the driving force is behind the agreement and what the benefits would be for New Zealand—with the USA being a protected market (heavily subsidised). Australia was described by a pharmaceutical industry representative as getting ‘trounced’ over their agreement with the USA, losing a lot of their pharmaceutical production and jobs as a result: Forget it…wouldn't even bother going along to the negotiations (PHCO); …tell the US to bugger off quite frankly. You either put everything on the table and we talk about it or no, you don't…We should learn from what happened in Australia… (PI)

Conversely, another participant suggested that while ‘America’ has influence, it may become limited as a result of the influence of China's developing economy and differing ideas around protection and new opportunities may develop: …a hugely developing economy in the form of China that basically has total disregard for such things…so the ability for America…is probably going to be limited in the world of the future, and maybe different forms of protection of ideas will kind of evolve…it's very hard to predict how the market might respond or what kind of new opportunities develop (PS)

A pharmaceutical industry stakeholder said Medicines New Zealand (New Zealand's prescription medicines representative association, same title as the policy) is attempting to ensure that its USA equivalent understands New Zealand's medicines system: …working quite hard to ensure…our sister organisation in the US is effectively asking the US government to achieve out of the process, is well enough informed to understand actually what the New Zealand model does achieve, what it doesn't achieve and how that can be improved…So we're working hard to make sure it's a process that actually benefits New Zealanders as well, and all of the transparency, timeliness, appeals—those aspects that we've discussed, are exactly I think what the US is likely to be asking for (PI)

Most considered that New Zealand's current ability to access generic medicines or independence in procuring medicines should be upheld. If not, funds may need to be redirected from other services or patient copayments would need to rise, in order to compensate a likely increase in the cost of medicines.

High-cost medicines

A GP questioned the necessity of continuing the Special Authority (SA)iii status for a medicine once the appropriate use of a medicine has been established. Not all participants were familiar with the Named Patient Pharmaceutical Assessment (NPPA)iv access scheme. Most high-cost medicines were described as being ‘breakthrough’ or ‘expensive’ and are restricted, to control spending. One participant said, if it was ‘dirt cheap’, there would be ‘no argument’, indicating the case even if the medicine did not have clear health benefits: My bet, is that PHARMAC would listen to anyone that agrees with them saying no. Because it's expensive…They are diametrically opposed for a reason and the reason is cost (Ph) The Rabbits in charge of the lettuce patch (M)

One PS stakeholder thought there to be no inappropriate blocking of access to medicines, as no complaints about access had been received at their level. Equally, another PS stakeholder commented that there are patients accessing medication costing up to NZ$500 000/year: …So it's not that the system can't cope with treatments that are high cost, it's just that we would expect a return for that cost and for it to be justifiable in terms of what we value (PS)

A small group of patients were described as not having access to high-cost medicines. Access was described as ‘the collective good’. On the other hand, ‘people dying from a lack of access to very cheap and simple therapies’ was described. It was suggested that it is DHB's remit to look after its population. A statement was made if we are advocating treatment at any cost: It's a question of who pays for all these things. I think if you have pretence; like there is in the USA, that cost isn't of any relevance…then you're going down the wrong path (PHCP)

The oncologist described the NPPA process as inefficient and that a comprehensive and referenced application takes him up to 6 h, potentially impacting on his clinic time and perversely hindering patient access. He suggested PHARMAC at a nominal cost could employ someone to aid in information gathering and, in the process, develop expertise.

Additionally, the oncologist believes oncology has the stigma that everyone dies but individual survival may be greater than the median survival assessment. This issue was presented in comparing the availability of two to three drugs in Australia that are unavailable in New Zealand.

Questions were posed: (1) is it fair to give fourth-line or fifth-line chemotherapy and not give a first-line treatment, for example, for rare disorders? and (2) when should one stop the treatment? A patient was described as gaining access to expensive medication; however, their condition was fragile and they died a few weeks later: I think it's important if Pharmac has a few loose strings in terms of hospital and severe rare conditions. They are perhaps because of how they are funded, they want a very narrow perspective on those, to try and avoid blow out. They are very emotive issues we don't always know how to best manage people's care (Ph)

High need patients, such as rare disorder patients, received the most sympathy for difficulty in access because of the exclusion criteria. Evidence requirements were described as difficult to attain due to the low patient numbers. Conversely, the PHCO suggested that the supplier needs to produce quality evidence: …where there's some evidence, but not solid or quality evidence:…the company doing the—providing the medication, it behoves on them to do some research in those areas and produce quality data (PHCO)

Discussion

We purposefully attempted to be open to issues and their capture, despite some issues already being identified. Our focus was on access to medicines. It is possible that there are other issues in existence that we neither recognised nor captured. We did not seek to determine issues specifically related to generic medicines, considered a ‘vital component of New Zealand's medicine cost management policies’ by Babar et al.12

Medicines policy

Medicines are clearly valued health interventions—evidenced by the budget, literature and responses from stakeholders. The smaller percentage spent on pharmaceuticals in New Zealand (described as a constrained budget), compared with similar countries such as Australia, the UK and the USA,2 may in fact reflect the price reduction strategies that are implemented by PHARMAC,32 as opposed to less opportunity to improve health outcomes. However, this needs to be tested through robust research on health outcomes and their relationship to pharmaceutical spending.

Delayed access and the resultant impact discussed by some of the participants was also described by Ellis and Hamer,33 in relation to New Zealand's statin availability for atherosclerotic patients, as probably negatively impacting the health outcome and considered to be due to the capped budget. They considered this as ‘anomalous’, as other types of healthcare are not capped. This anomaly was also described by a number of participants but may change with PHARMAC's expanding role.

New medicines are increasing in cost, along with demand, causing tension in affordability. Price efficiency initiatives, such as what PHARMAC encourages, help ease the tension in affordability of provision. Another option is to reduce demand, either through ‘gate keeping’ (not usually a popular choice) or genuine effects, such as initiatives to maintain health or prevent disease. We assume that a reduction in demand and therefore burden of provision should result in healthcare becoming more affordable for providers and helping those remaining in need.

Manning34 compared the processes of decisions, pricing, economic analysis, provision and access and participation and appeals between the UK, Australia and New Zealand. It was suggested that resolving issues may benefit from a disputes panel comprising a broad range of experts in scientific, economic, policy and ethical evaluations, in order to provide an objective decision. Manning additionally reported that approximately one-sixth of the UK's National Institute for Healthcare and Care Excellence (NICE) recommendations are appealed and upheld.35 There should not be great demand if the evaluation processes are robust.

Ethnicity

Our participants revealed that low socioeconomically related populations (encompassing Māori and Pacifica people) are continuing to have access issues related to financial, structural, educational and cultural barriers. These findings were consistent with that of Jatrana et al,36 who assessed SOFIE-health's 18 320 respondents (an add-on to Statistics New Zealand's longitudinal survey of Family, Income and Employment). Māori and Pacific people were more likely to defer purchasing a prescription due to cost, which at that time was NZ$15.

Māori represent approximately 15% of New Zealand's population37 and on average have the poorest health status of any ethnic group in New Zealand.38 ,39 Pacifica people represent 6.5% of the population and also experience health inequalities. He Korowai Oranga: the Māori Health Strategy (2002)38 recognises the Treaty of Waitangi principles of: partnership, participation and protection, through which the aim is to reduce the existing health inequalities. This aim is extended to include the Pacific people, who like Māori are over-represented by a low socioeconomic situation, reflecting low affordability and health literacy, which in turn affects access. The Ministry of Health recently launched SIA40 an additional targeted capitation payment, available to primary healthcare organisations to reduce health inequalities. It is designed for new services (eg, outreach programmes) or improving access (eg, funding transport) for Māori, Pacific people and those of low socioeconomic status. Once SIA is embedded, it would be prudent to evaluate its impact.

Other Ministry of Health initiatives, such as Whanau Ora (to build the health, participation and capability of families) and One Heart Many Lives (to improve the cardiac health of Māori and Pacific men) along with recent changes in health practitioner training, appear to be good initiatives for engaging Māori and Pacifica in a culturally appropriate way. It would be prudent to evaluate their impact.

We did not have any issues specifically described for new immigrants. It was described to us that patients with poor English speaking capability present to practitioners with an English speaking person, or frequent a surgery of their ethnicity. This is at odds with Babar et al,9 who found for 11 Chinese and Indian migrants, residing in New Zealand for less than 5 years, that financial barriers existed in affording doctors, pharmacists and medicines, and that language barriers exist. This anomaly may highlight the differences in the perspective and experience of the stakeholders we interviewed.

Asia and India have different medicines access systems to New Zealand. Babar et al additionally found that there is a lack of information on New Zealand's medicines system, including medicines provision and classification. The United Nations and World Health Organisations, when discussing the right to health,41 refer to migrants as being vulnerable to reduced access to health services for reasons that include language or cultural barriers. New Zealand has a significant migrant population, reported as 927 000 in 2006.42 The current main countries for immigration are: China (15%), the UK (unspecified), India (13%) and the Philippines (8%).42 In consideration of Babar et al's work and immigration statistics, there may be a significant number of people from these countries with issues, resulting in difficulties in accessing healthcare and therefore medicines.8–10 In the light of this, it may be worth investigating new immigrant issues further.

PHARMAC

The general appreciation for New Zealand needing to be efficient, in order to provide more medicines, expressed by our stakeholders was also shown by Ragupathy et al.26 Included was the need to apply consistent economic evaluations to other health technologies, to support congruous decisions for resource allocation. PHARMAC's expansion into procuring hospital medicines and medical devices may enable greater consistency of evaluation across technologies.

The significance of PHARMAC's role expansion should not be underestimated. PHARMAC will need to exercise caution when expanding its role into hospitals, which are generally settings of acute and moribund disease. We are unaware whether a closed formulary has occurred elsewhere in the world. PHARMAC has been noted to have consulted directly with medical specialist groups to discuss their role expansion, including consultation on hospital medical devices,43 so it would appear to be fully cognisant and appreciative of this issue.

We found delays of up to 8 years in PHARMAC's process for funding medicines onto the Pharmaceutical Schedule, which a number of our participants purported to be due to the medicine's pricing and/or PHARMAC's budget not being able to expand. Other reasons may be the medicine's priority status, insufficient information or not meeting PHARMAC's nine decision criteria.44 The question is whether this means delays in therapeutic advancement and therefore improved health outcomes.

The measurement of opportunity foregone was of clear concern to the oncologist we interviewed. New Zealand has a capped medicines budget; it cannot expand and therefore drives the need for efficient spending (determined using cost utility analysis, where medicines are assessed against QALY gains per NZ$1 million). Using this process for provision means there is opportunity foregone, as described by Milne and Wonder.14 We are not aware of New Zealand focused research assessing either opportunities foregone or other specialist viewpoints on access, the exceptions being: Ellis and Hamer33, discussing the delayed availability of cardiac medicines; MacCormack et al31 in 2009, assessing stakeholders’ views on needed access to high-cost medicines and the Sage report for the Ministry of Health in 2010,22 reporting the consultation of stakeholders on the proposal to expand PHARMAC's role.

Sole supply issues (supply outages, lack of palatable formulations, resultant out-of-pocket payments for alternatives and vulnerability as a result of a disaster) were reported to be continuing, despite there being penalties for suppliers. This was also reported by Babar et al,45 who reported additional concerns with poor quality products in the past, from previous studies.

Trans Pacific Partnership Agreement

There is very little information available on the TPPA; the reason given is, particulars of the negotiation are changing. What does exist concurs with our findings; it questions the motivation and self-interest of parties involved and warns of possibly binding impacts that may affect health services budgets and PHARMAC's autonomy, including method of procurement and provision.25–29 ,46 Such impacts stem from the USA's desire for stricter protection of intellectual property rights, transparency of in-house evaluation, regulatory coherence, dispute settlement, government procurement and evidence-based decisions being contestable in court. Unless budgets expand to cope with likely increases in costs, there may need to be a re-evaluation of provision, subsidies and copayments. In contrast to existing publications, our research additionally suggested that a TPPA may enable earlier access to newer medicines. It may be of use to quantify what effect a TPPA would have on medicines access.

High-cost medicines

A significant issue discussed in our study was the need to differentiate between high-cost medicines and highly specialised needs and medicines in relation to the NPPA access scheme. McCormack et al31 suggest that a medicine that costs NZ$20 000 per patient per year may be considered high cost. It is important to be cognisant of the total cost to the health system of any medicine, which is dependent on the number of patients treated (volume used) and the acquisition price. Some high-cost medicines may not result in a high total cost to PHARMAC, for some patient groups. Gallego et al47 question how treating large populations at high total cost for small population gains compares with treating smaller populations, for possibly significant benefit.

The issue of treating large versus small populations may intensify with patient subtyping and genomic medicines development (as described by the oncologist) where greater expectation to fund (ie, demand) may occur. With the NPPA process now reported in our findings as enabling the capturing of patients with cancer subtype information, cancer medicine outcomes may become easier to measure and, if positive, make it harder to decline funding treatments. It may also mean the table is turned and large populations end up having limited treatment options, if outcomes cannot be measured in the same way. However, funding outcomes will give a clear indication for innovation and direction to suppliers and funders of medicines.

Our findings describe the SA and the NPPA access schemes as being inefficient. The SA inefficiency finding is also supported by Babar et al’s45 evaluation of GP perceptions on access to medicines in New Zealand. Once correct prescribing of a medicine has been established, it may not be necessary to continue a medicine's SA status. The NPPA process appears to impact significantly on consultant clinic time, which may perversely hinder patient access. With demographic trends indicating greater demand for such medicines, the impact of the inefficiency may intensify. PHARMAC's website lists 555 approvals and 15 declines for NPPA access.48 The high rate of NPPA approvals brings into question the need for such a process. Alternatively, it may be more efficient for PHARMAC, at a nominal cost, to contract an evidence-based facilitator, to ease the burden of application for clinicians.

Difficulty in access to high-cost medicines, encompassing rare disorder patients, as described by our participants, has been widely documented.31 ,47 ,49–58 The nature of rare diseases makes it hard to gain the necessary evidence PHARMAC requires for evaluation. This issue is compounded for suppliers because the need to satisfy manufacturer ordering and regulatory requirements adds to the unit cost of supply for low-volume demand medicines. It may be worth investigating options to reduce cost of supply and provision in the context of constrained evidence. PHARMAC has recently sought public and professional input into its decision criteria. The results have yet to be published but may reveal new options or initiatives.

Our research highlighted the issue of access to medicines of therapeutic value in the context of a fixed predetermined budget and the difficulties in how priorities for funding are determined. Lu et al,59 discussed the ethical perspectives and access to high cost medicines outlining that ethical aspects could help to achieve the fairest outcomes for individual patients, as well as for the community. This does come with ethical concerns but may enable access and capturing evidence. MacCormack et al31 suggest ‘risk sharing’ supply to ensure some form of access (defining a threshold for maximum numbers to treat for a high-cost medicine above which the supplier funds)

Conversely, Simoens et al52 caution providing access to medicines with limited effectiveness, implying that rare disorders health improvement is more valuable than a common disease, which challenges the utilitarian view that the health gain of each patient is valued equally. With increasing effort in the development and availability of orphan drugs, this issue may only worsen. Equally, other questions arise: because we see that ill health cannot mean preferential treatment over someone who has a ‘silent’ state of declining health. There are people not getting access to inexpensive medicines, who are at risk, as stated by an academic. Perhaps remedying issues of access based on need could start with prioritising based on the impact of an unmet need?

Conclusion

Overall, despite issues being identified, there was reasonable satisfaction with New Zealand's medicines policy and its principles. In particular, that provision is evidence based, cost effective and there is equitable ability to have prescribed medicines listed as subsidised, on PHARMAC's schedule.

However, despite this, there appear to be some patient groups still experiencing difficulties in access, not necessarily appearing as a result of medicines policy or PHARMAC, such groups being rare disorders and the low socioeconomic (encompassing the rural, Māori and Pacifica populations). Other issues ranged from: the pharmaceutical industry's pricing of new medicines; manufacturer and registration requirements; the submission for funding process; increasing demand for medicines and the resultant financial impact; budgetary constraints; cultural and health literacy; patient affordability and access to prescribers; through to knowledge development for clinical expertise and the measurement of health outcomes.

Our study has highlighted issues in access based on need and the consequences of unmet need, the context being that a fixed and predetermined budget, increasing demand and rising cost of medicines are all compounding constraints in affordability. We suggest that these issues and consequences of unmet needs may worsen and options for demand and provision may need to be explored further.
