Provincial elections and timing of cancer drug funding

A. Srikanthan, MD,* S.S. Gill, MD MSc, and K.K.W. Chan, MD MSc



Concerns have been raised about the potential influence of political pressures on drug funding decisions. We evaluated the temporal relationship between cancer drug funding and provincial elections in 9 Canadian provinces.


New indications for cancer drugs between January 2003 and December 2012 were identified, and the dates of official provincial funding dates and election dates between 1 January 2003 and 31 December 2014 were retrieved. The probability of drug funding announcements in the 60-day period preceding a provincial election was evaluated using binomial probability distribution analysis.


Data from 9 provinces (all Canadian provinces except Quebec) were available. During the period of interest, 69 new indications for 39 individual drugs were identified. Variation in the availability of funding dates was identified. At the time of data collection, 2 provinces did not have data available for all 69 indications. For the 9 provinces, the number of funded indications during the 60-day period preceding an election ranged from 0 to 3; however, no differences in the proportion of indications funded pre-election were identified. Additional analyses also failed to demonstrate any significant associations with the 90-day period before an election, or the 60- and 90-day periods after an election.


We observed no clear temporal relationship between provincial election dates and funding decisions in this recent Canadian sample of new indications for cancer drugs.

Cancer drugs are increasing in both number and cost1. Internationally, governments face challenges prioritizing funding decisions2,3. To ensure fairness, many countries use rigorous processes in an attempt to ensure equitable use of constrained resources4,5.

In Canada, national evidence-based reviews have been standardized to evaluate the efficacy and cost-effectiveness of new cancer agents6. Although evidence of efficacy is necessary, multiple other factors can influence the decision to fund a drug at the provincial level3,7. Potential external factors include the influence of media, patient advocates, politicians, and the pharmaceutical industry7. Involvement of those various policy actors was discussed in a study examining Ontario’s funding of trastuzumab, a cancer drug used to treat breast cancer, compared with a number of other cancer drugs7.

Despite pressure from multiple stakeholders, there is a public expectation that certain aspects of health policy remain protected from political influences. In Canada, the Canada Health Act supports a near-universal health care system; however, provinces independently make coverage decisions based on local constraints8. Furthermore, the Canada Health Act applies to insured health services, defined as physician care and hospital care; drug coverage is not considered an insured health service under the Act. The timing of drug additions to the various provincial formularies can therefore vary, in some cases by years9.

Speculation has been raised concerning the effect of political forces on health policy decisions10. During pre-election campaigning, political parties often use various promises or incentives to win votes from the electorate, including the promise of funding for various resources. Capturing the nuances of political pressure on drug funding decisions is challenging; however, elections have been suggested as one quantifiable method11. A case study involving dementia medications demonstrated that impending elections appeared to affect the timing of drug funding announcements, despite an established structure for evidence-based decision-making11.

Cancer drugs in Canada are reviewed through a similar evidence-based review process that includes cost-effectiveness analyses. Before 2007, Canadian provinces and territories had separate regional cancer drug review processes to inform their local funding decisions9,6. In 2007, the interim Joint Oncology Drug Review (ijodr) was created to facilitate the implementation of a single drug review process. The ijodr represented an evaluative process in which one province conducted reviews and shared results with the other provinces. After an evaluation of the interim process, the Conference of Deputy Ministers of Health approved the creation of a permanent body in 2010. The pan-Canadian Oncology Drug Review (pcodr) began accepting drug submissions for review in July 2011. This formalized national body conducts reviews on behalf of all provinces and territories except Quebec6.

Given the highly political nature of cancer drug funding, the association with campaign promises and elections, and evidence of an association between elections and timing of drug funding decisions in Canada, we hypothesized that there would be an association between election dates and cancer drug funding announcements. We therefore evaluated the effect of provincial elections on cancer drug funding decisions by individual Canadian provinces.


In this retrospective cohort study, we identified all cancer drugs with a distinct indication and with a Notice of Compliance (noc) issued by Health Canada between 1 January 2003 and 31 December 2012. The year 2003 was selected as the start year because of a lack, before that year, of consistent data to link noc dates to specific indications. The 2012 end date was chosen to provide sufficient time after a noc date for a drug to be reviewed and considered for a provincial formulary.

Drug funding dates in each province for the identified indications and provincial election dates were gathered for the period 1 January 2003 to 31 December 2014. We contacted pcodr to facilitate collection of certain data variables from the provinces; pcodr was blinded to the study objective throughout the proposal development, data collection, and data analysis stages. Quebec was not included in the analysis because that province is not part of pcodr.

Data Sources

Health Canada internal databases were accessed to identify all cancer drugs and indications. The publically available Drug Product Database Online Query tool maintained by Health Canada ( was used to manually corroborate all drug and indication entries. Individual provincial ministries of health, cancer agencies, and pcodr were contacted to obtain drug funding dates by individual province. Contact with provincial ministries of health and cancer agencies was facilitated through pcodr and the pcodr Provincial Advisory Group Working Group. Provincial election dates for the 9 provinces of interest (Alberta, British Columbia, Manitoba, New Brunswick, Newfoundland and Labrador, Nova Scotia, Ontario, Prince Edward Island, and Saskatchewan) from 1 January 2003 to 31 December 2014 were extracted from publicly available Web sites (Table i).

Data Collection Process

Health Canada provided a list of all drugs and associated indications classified as antineoplastic and immunomodulatory. Veterinary entries were excluded. That dataset was manually reviewed against the Drug Product Database Online Query tool to extract noc dates of interest for each unique indication.

Using a prospectively defined electronic data extraction sheet, 2 individuals (AS and a pcodr staff member, Nianda Penner) independently extracted data. A third individual (pcodr staff member Helen Mai) resolved any discrepancies. Duplicate entries were removed so that the final data set included 1 unique noc date per drug per unique indication. The electronic drug monographs available through the Drug Product Database Online Query Web site were used to corroborate drug indications. Notice of Compliance entries were removed when the entry concerned various strengths of a drug, a non-cancer drug or indication, a discontinued drug, or replication because of a change in manufacturer or manufacturing process. It was not possible to link an individual indication to a specific noc date for all older drugs. Drugs with a first noc date before 1 January 2003 were therefore excluded.

Variable Definitions

Extracted variables of interest included the drug name; drug indication; province; noc date; submission period (pre-ijodr era, ijodr era, or pcodr era); tumour site; route of administration; provincial funding status; provincial funding date if the drug was funded; provincial election dates; and incumbent party on 1 January 2003 and subsequent election winners.

Statistical Analyses

Before analysis, provincial identifiers were removed, and results were anonymized. Anonymization was necessary to obtain interprovincial collaboration. Descriptive statistics are used to summarize characteristics of the evaluated drugs and indications.

The time from drug funding date to closest provincial election date was calculated in accordance with previously published literature11. Funding decisions made in the 60-day period preceding a provincial election were identified. The 60-day period was chosen because that is a typical time interval between the formal announcement of a provincial election and the voting date, and it is representative of the time when political parties most actively campaign to gain voter support.

To establish whether there was a statistically significant change in the probability of a drug funding announcement being made within the 60-day interval before a provincial election, a 1-sample test of binomial probability was performed. The null hypothesis was that the observed probability of a drug funding announcement within the 60-day period preceding an election is not different from the expected probability based on chance only. The expected probability was defined as the probability that a funding announcement would be expected in this period by chance alone; it was calculated by determining the proportion of time an individual province spent in the 60-day pre-election periods between 1 January 2003 and 31 December 2014. Specifically, for each province, the number of provincial elections that took place during the 12-year study period (4380 days) was identified, and the total number of days spent in the 60-day intervals before elections in each province was then determined.

The 1-sample test of a binomial proportion was applied to compare the observed proportion of funding announcements within the 60-day intervals before an election with the null hypothesis value. Table ii provides further details of the expected probabilities and the null hypothesis. No attempt was made to censor events or to model them in a time-to-event fashion.

Calculation of expected probability for null hypothesis

Using a 1-sided alpha of 0.05, the calculated null hypothesis (0.0457 of cancer drug funding decisions would, by chance, fall within the 60 days preceding an election), and the 275 drug funding decisions across the country, our study would have 80% power to detect a higher proportion of drug funding decisions (alternative hypothesis of 0.08) falling within the 60-day period before an election. Additional analyses were conducted in a similar manner for the 90-day period before an election, the 60-day period after an election, and the 90-day period after an election. Statistical significance was 1-sided and defined as p < 0.05. The statistical analyses were performed using the IBM SPSS Statistics software application (version 21: IBM, Armonk, NY, U.S.A.). No correction was made for multiple statistical testing.


Baseline Characteristics

Health Canada identified 2211 indication entries. Excluding duplicate entries, non-cancer indications, discontinued drugs, and drugs with an initial noc date before 1 January 2003, 69 indications representing 39 unique cancer drugs (chemical entities) remained (Figure 1, Table iii). Table iv lists the characteristics of the indications.

Characteristics of Available Provincial Data

The availability of drug funding dates varied for the 9 provinces (Table v). For two provinces (6 and 8), data for all 69 indications were not available at the time of data collection, because a centralized process for record-keeping was not available. Missing data all related to the pre-pcodr period, and all affected drugs were intravenous medications. Variation between the 9 provinces in the time to initial funding was identified. A funding date from more than 1 province was available for 55 indications. When more than 1 province provided a funding date, the duration from the earliest funded date to the latest funded date for an indication ranged from 0 to 3469 days (median: 646 days).

Influence of Elections

For the 9 provinces overall, the proportion of indications that were funded during the 60-day period preceding an election was low. For the individual provinces, the number of indications funded during the 60-day period preceding an election ranged from 0 to 3; however, a statistically significant increase in the proportion of indications funded in the 60 days before an election was not identified (Table vi). A similar analysis conducted for the 90-day period preceding an election, the 60-day period after an election, and the 90-day period after an election also did not demonstrate any statistically significant increases in the proportion of indications funded, with the exception of 1 province in the 90-day period after an election (Tables viiix).

No similarities between the provinces were found with respect to the drugs that were funded in the 60-day period preceding an election. Across Canada, a total of 7 different indications were funded during such a period. Of those 7 indications, 2 were funded in the ijodr era, and 5 in the pcodr era.


Our study did not produce any evidence that provincial elections systematically influence funding announcements for cancer drugs in Canada. Although provinces varied with respect to the number of drugs funded immediately preceding an election, the proportion of drugs funded was not greater than the proportion anticipated because of chance alone. Given the previously identified concern about elections influencing drug funding announcements in specific cases11, that negative finding provides some reassurance.

Yet despite the reassurance, concerns persist about cancer drug funding decisions. Provincial elections represent one relatively obvious form of political pressure; the potential for other forms of political influence to affect cancer drug funding decisions is difficult to rule out. Drug funding remains a highly political topic, subject to lobbying from many stakeholders, including patient advocacy groups and pharmaceutical companies7. Those factors do not operate in isolation, and various stakeholders and the media likely have an interdependent relationship with respect to the drug funding issue7,12. The complex interplay of those multiple factors is considerably more difficult to quantify and to study than are the dates of provincial elections.

Government action is necessary to produce outcomes that individuals cannot produce for themselves10. From the perspective of policymakers, “problems” are conditions that members of the public find unacceptable and for which change is desired13. Translation of any health condition into a political problem occurs through the mobilization of individuals who recognize that their personal needs are shared by others and who subsequently demand action from public officials. Political action can be induced through public opinion, emergence of social movements, interest group mobilization, or voting10. Strategic policy agenda–setting and innovative seizing of opportunities by policy entrepreneurs will therefore continue to affect cancer drug funding.

The rigorous and time-intensive review process for cancer drugs in Canada might explain why more drug funding approvals were not identified in the chosen 60-day window. Few data to evaluate the length of the drug review process before the implementation of pcodr in 2011 are available. The length of the process might render manipulation for political ends difficult. Alternatively, a lengthy drug review process with multiple stages might allow for increased manipulation, because a consistently short review process arguably provides fewer opportunities for influence. It is unclear how the implementation of pcodr might have influenced our results, because the number of drugs identified in the 60-day window before an election was too small to conduct subgroup analyses. The establishment in 2010 of the pan-Canadian Pharmaceutical Alliance ( to lower drugs costs and increase affordability could further influence the process in unknown ways.

Although our study demonstrates that a systematic use of political influence via elections is not occurring, published evidence has shown that, in certain situations, politicization affects cancer drug funding7. How health care issues are defined and recognized within existing social conditions and policies becomes increasingly important in ensuring adequate availability of effective drugs for oncology patients. The ability to ensure that issues of interest are on the policy agenda and are framed in a manner to allow positive funding decisions calls for the involvement of various stakeholders. Given that few studies have evaluated the effect of politicization on cancer drug funding, ongoing evaluation of external factors affecting drug funding decisions is necessary.

Limitations of our study include our inability to capture all the nuances that contribute to a drug funding decision. For example, we were unable to capture the effect of lobbying by manufacturers and patient advocacy groups. There is also a lack of transparency in negotiations between provincial governments and manufacturers—negotiations that undoubtedly shape final funding decisions. Additionally, the date of funding recorded in provincial formularies can be different from the date of the funding decision. The dates of funding decisions were not consistently available for all provinces; any relationship between strategic funding decisions and elections could not, therefore, be assessed. Any times lapses between funding decisions and subsequent funding announcements would not be captured in our study. It is a point worth highlighting that every drug funding decision is unique in terms of the disease involved, the alternative treatments available, and the costs and overall budget impact of the new drug being considered for funding. The relatively small sample size in our study is another limitation; however, a larger number of observations does not yet exist. The small sample size might prevent associations from being identified and limits the possibility of undertaking a multivariable analysis evaluating potentially explanatory variables (such as health spending per capita). It is also unclear how a “conditional approval” status rendered by pcodr affects provincial funding decisions, adding another layer of complexity to the interpretation of our results.

Despite those limitations, our study evaluates a large number of cancer drug indications relative to election timing. Furthermore, by evaluating multiple drug classes over a 12-year period, the generalizability of our results is increased.


We found no evidence of a systematic bias to fund cancer drugs near recent provincial elections. Despite that reassuring finding, further studies into the effects of politics and agenda-setting on cancer drug funding is necessary to ensure that priority-setting remains a legitimate, transparent, and fair process.
