Utilization of over-the-counter analgesics in two private medical insurance schemes in South Africa.

INTRODUCTION: In South Africa there is an easy access to over-the-counter (OTC) medicines and expenditure is high. Certain OTC products are available to the public in general stores, while others may only be available at pharmacies. It is also common for OTC medicines to be prescribed by a doctor for treatment of minor illnesses. Individuals with medical insurance usually have cover for these products, but typically only to a limited extent. AIM: To investigate the utilization patterns in two medical insurance schemes of OTC analgesic products in the Anatomical Therapeutic Chemical (ATC) category N02BE51 which includes medicines containing paracetamol and varying combinations of codeine, caffeine and antihistamines.
METHODOLOGY: Data were obtained for two benefit plans, one with generous, high benefits (HI), the other with lower benefits (LO). Data covered utilization of OTC medicines in the N02BE51 group, indicating whether the medicines were purchased at a pharmacy or dispensed by a doctor. Doctors were further categorised as contracted/network or non-network providers. Product costs and volumes were analysed according to access directly by the beneficiary, recommendation by a pharmacist, or prescription from a doctor.
RESULTS: Compared to doctors, pharmacists issued more-expensive products. Average costs were higher in the HI plan compared to the LO plan. Pharmacists showed a preference for dispensing larger and more expensive pack sizes. Doctors showed better cost containment: the average cost of products in HI was twice that of LO. Doctors dispensing directly to patients issued smaller pack sizes and lower-priced products. Contracted network doctors did not appear to impact on costs.
CONCLUSION: Among the privately-insured individuals studied, the avaiIability, cost and formulation of N02BE51 OTC products appeared to be poorly regulated, whether by the consumer, pharmacist, medical insurance scheme or legislation. Doctors demonstrate better cost containment by prescribing less costly, smaller pack-size alternatives compared to pharmacists.

Introduction

By definition, “ethical medicines” are medicines that can only be accessed by patients on a doctor’s prescription. Over-the-counter (OTC) medicines are not subject to such control and, being more available, contribute significantly to South Africa’s annual healthcare expenditure. According to reliable industry information, in 2015 R39.5bn was spent on all medicines (R=South African Rand; in 2015 R12.6=1US Dollar). The OTC market accounted for almost 26% of the total amount (R10.2bn)1 One particular manufacturer featured as the leader in OTC sales, an achievement highlighted in the company’s 2018 annual report which showed OTC market growth of 7.6% (calculated at R1.898bn).2

The ease of access to OTC medicines by consumers has resulted in a perception that the products are harmless and do not pose health or other risks.3 These medicines, available without a prescription, are categorised by the national accreditation and registering body as Schedule 0,1 or 2 medicines.4 Schedule 0 medicines are available at general stores and supermarkets, while Schedule 1 and 2 medicines (S1,S2) are kept behind the counter at pharmacies but can still be purchased without a prescription.4 Many OTC products are “poly-pharmaceuticals” and contain mixtures of various Schedule 1–2 medicines, but the evidence base for their effectiveness is generally lacking. Most have “flown under the radar” in terms of safety with the exception of ephedrine, pseudoephedrine and codeine. In the latter cases the Medicines and Related Substances Act 101 of 1965 was amended to limit the milligram quantity of these substances in OTC preparations and restrict the number of packs that an individual is able to purchase.5–7 While placing the above restrictions on access to codeine, the legislation is less prescriptive about the poly-pharmaceutical formulations of OTC medicines. Freely available to the public via cash payments, OTC medicines are also available to medically-insured beneficiaries via their “medical aid schemes”, whether accessed directly by the beneficiary, recommended by a pharmacist or prescribed during a doctor’s consultation for treatment of a minor illness. In South Africa private health insurance is provided by not-for-profit medical aid schemes. In 2015 there were 87 medical aid schemes registered with the Council for Medical Schemes (CMS), the Government regulatory body.8 Each one offers access to a range of medical, dental, optical, paramedical and medicinal services known as “benefits.” Benefit combinations vary between medical aid schemes, with each combination termed a “plan” or “option”. Health plans are purchased by “beneficiaries” on the basis of affordability and healthcare needs. Where healthcare is accessed within the public sector which serves more than 80% of the population, S1,S2 medicines are prescribed and dispensed according to the South African Essential Medicines List (EML) which is a formulary with a limited number of OTC medicines, typically only includes single-compound products and does not include combination medicines.9

An additional issue with OTC medicines is that the combination and concentration/strength of ingredients may be identical or differ only marginally between products, yet prices vary markedly without sound basis. However, it is not only the varying cost of the products themselves, but also the potential costs of their adverse effects that are important. For example, a study by Friedman showed that cheaper, “old generation” sedating antihistamines were easily accessible for allergic conditions, but the long-term cost impact of the adverse effects of these drugs had not been considered.10 In terms of potential costs of adverse outcomes, the codeine-containing medicines represent a category that raises or should raise concerns in the country. As a result of legislation, OTC medicines are restricted to 10mg of codeine per dose.7 While this is restrictive, it does not limit the risk of addiction.11 Codeine abuse is currently receiving attention globally, with Australia removing codeine-containing OTC preparations and “up-scheduling” them to the “prescription only” category,12 while measures to restrict access are also being considered in the United States and Canada.13,14

Council for Medical Schemes annual reports indicate that a high percentage of covered beneficiaries access the OTC benefit, irrespective of whether they have restricted or generous benefits.8 Furthermore, as shown by others, it appears that the higher the available benefit, the more tends to be spent on an event, despite the fact that spending more-carefully would extend the value of the benefit.15 Medical aid schemes provide little in the way of member education and also have few, if any, cost-containment initiatives within the OTC benefit.8 This may be because schemes have limited interest in how the benefit is used. It is typically capped in one way or another and structured in such a way that it functions as a debit card account, to be used at the discretion (or indiscretion) of the beneficiary concerned.

Access to care, cost of care and quality are key elements in any discussion around a health system. The aim of the present study is to investigate the utilization patterns in two South African medical aid schemes of a high-impact set of OTC products. As such the focus was on analgesic products in the Anatomical Therapeutic Chemical (ATC) N02BE51 category which includes medicines containing paracetamol and varying combinations of codeine, caffeine and antihistamines. The study addresses individual products and explores costs, volumes and elements of quality, the latter mainly related to regulatory oversight of pricing and formulation of products in the ATC category under review. We also discuss findings in relation to the current national debate around costs in the private sector in general, and the intended transition to universal, affordable access to quality healthcare.

Methodology

Beneficiaries were selected from a 2015 database provided by a large medical aid scheme administration company in South Africa. Administration companies take on the day-to-day operational activities of one or more medical aid schemes. Services range from enrolment of members to payment of claims, actuarial services and production of management reports. The administrator who provided our data has been in existence for over 40 years and serves more than 3 million lives within a number of medical aid schemes. The various medical aid schemes, their specific benefit options/plans and beneficiaries were not identifiable; as such all data were confidential. One year’s data was provided for analysis covering 12 plans with 641 525 beneficiaries in total. Only two plans were selected for this study, one within a high benefit medical aid scheme with a comprehensive set of generous benefits (designated HI), the other offering a lower benefit plan (designated LO). In both plans there was access to OTC medicines up to specified limits.

Beneficiaries were identified only by a unique study number. Background information provided for each beneficiary included gender, age and ethnicity. Medicines data extracted included only S1,S2 medicines. Those prescribed or dispensed by a doctor are referred to as doctor-prescribed (DP) medicines, while those accessed directly by the beneficiary or on the recommendation of the pharmacist are referred to as beneficiary/pharmacist (BP) medicines. In the South African context all medically-qualified and registered practitioners are referred to as doctors, whether general practitioners, specialists or sub-specialists in the various medical and surgical disciplines.

Actual indication for the medicines could not be ascertained because of the frequent use of a non-specific diagnostic ICD10 code such as in the Z76 category which covers “Persons encountering health services in unspecified circumstances.”16 Each medicine claimed was coded according to its ATC classification.17 Within the ATC system medicines are grouped into five levels (anatomical main group, therapeutic subgroup, pharmacological subgroup, chemical subgroup and chemical substance). One of the most-frequently accessed categories, N02BE51, covers N: the nervous system, 02 represents analgesics, BE and 51 cover paracetamol and its combination with various ingredients, excluding psycholeptics. In South Africa this ATC category includes a large number of products, most of which have varying combinations of a relatively limited number of ingredients. Products may be original or generic and be priced very differently, in many cases for identical formulations.18

This ATC category was selected not only because its overall utilization was high in both HI and LO plans, but also because of the potential for products in this category to present with adverse drug reactions.19 For both HI and LO plans the top 10 N02BE51 products were selected based on volume, whether accessed via the DP or BP route. The contribution of each product to the total cost within the ATC was calculated, together with the average cost of each product as submitted to and paid by the medical aid scheme. To establish whether the HI and LO plans selected for this study were representative of utilization in other plans, five other plans were randomly selected from the database of 12 plans. A correlation analysis was performed for the top products of the five against the products accessed within the two plans used in this study. Results showed correlation coefficients that ranged between 0.84 and 0.99, with p-values ranging from <0.005 to 0.000. Statistical analysis was carried out using Statistica (Version 13.2 TIBCO Software Inc., Palo Alto, CA, USA) which was also used for descriptive statistics and frequency analysis. Significance was set at p˂0.05.

In the DP option in both plans, the top 10 medicines by volume were further separated, based on whether they were prescribed by a formally-registered dispensing doctor (who stocks medicines within her/his practice) or a non-dispensing doctor (who writes a prescription for dispensing by a pharmacist). An additional level of service provision and DP-prescribing explored the involvement of contracted, preferred/designated service providers (DSPs), alternatively referred to as “network doctors”. This applied only to the LO plan as it was not a managed care strategy employed by the HI plan.

Ethics approval was obtained from the Human Ethics Committee of the University of the Witwatersrand (certificate M160141).

Results

Table 1 shows the ranking of 14 branded products in the NO2BE51 ATC by composition and volume in the HI plan, whether BP-dispensed or DP-prescribed. Six products were common to both DP and BP. The generic use within both DP and BP categories was similar. Of the top 10 in both BP and DP categories, seven of the products have the same chemical composition, yet prices ranged between R7.54 and R110. The average cost for the top 10 in the BP category was R66.82 in contrast to R44.73 in the DP category.

Table 2 shows volume and cost comparisons for identical products prescribed by non-dispensing and dispensing doctors. When comparing identical products dispensed by the two doctor groups it is clear that the dispensing doctors showed better cost containment. For the non-dispensing doctors the medicine costs were almost twice as high as those of the dispensing doctors. Two products (A1,A2) have similar ingredients but costs ranged between R28.08 and R109.96. Some of the large price differences could be the result of differing pack sizes. This is explored below (Table 3).

Table 3 compares the frequency with which smaller and larger pack sizes of the two most commonly utilised products (A1, A2) were dispensed between three groups: dispensing doctors, non-dispensing doctors and pharmacists. Frequency analysis showed that there was significantly more dispensing of large packs by pharmacists, while dispensing doctors were significantly less inclined to do so. This had an impact on costs reflected in Tables 1 and 2.

Table 4 shows the ranking of 15 branded products by composition and volume in the N02BE51 ATC in the LO plan. Five products were common to both DP and BP categories, with almost complete use of generics in both. Eight products contain similar ingredients. The average product price in the BP category was more than double that of the DP category (R42.43 vs R19.19). The use of smaller pack sizes is detailed below (Table 6), but the choice of cheaper generics by doctors and proportionally lower dispensing fees may also have distorted the average cost in favour of the doctors.

Table 5 shows the cost differences for products common to both non-dispensing and dispensing doctors. For four of the six common products the costs were very close, however once again for the two generics that contain paracetamol, caffeine, doxylamine and codeine there was a substantial difference. This is shown below as a possible manifestation of pack size differences (Table 6).

Table 6 shows frequency of dispensing by dispensing doctors, non-dispensing doctors and pharmacists. In comparison with the HI plan there appeared to be more “balanced” use of smaller and larger pack sizes, but frequency analysis showed again that pharmacists, and to an extent non-dispensing doctors, resorted to larger pack sizes than dispensing doctors. There was an impact of pack size dispensing on costs as reflected in Tables 4 and 5.

Table 7 shows costs attributable to different doctor categories. Network doctors are doctors who have service-level and payment agreements with medical aid schemes. These doctors were further categorised as either dispensing or non-dispensing doctors. There was not much difference in costs between network and non-network doctors, irrespective of whether they dispensed directly to patients or wrote prescriptions for dispensing by a pharmacy. However, as shown in previous Tables, the average cost remained higher for the non-dispensing doctors compared to the dispensing doctors (R31.06 vs R19.47).

Discussion

This study focused on 14 branded products in the N02BE51 ATC category representing 'top 10' expenditure in the HI plan and 15 products in the LO plan. Overall, 50 mostly-paracetamol-based and codeine-containing products were dispensed in the NO2BE51 category, with variable prices but limited differences in terms of their composition. South Africa has “single exit price” legislation that compels all manufacturers to declare the price of each product and seeks to ensure that prices are not inflated at points of sale.20 However, as shown in this study, there is no requirement for manufacturers to justify prices or show how they were derived. This results in identically-formulated products having markedly differences prices. This aspect is confirmed and covered in detail in a recent report which showed that two-thirds of 6613 products across the ATC categories were formulated identically to one or more others.18 The use of several generic products in this study raises the question of whether similarly-constituted products are always and reliably clinically equivalent. This is an important issue that has been reviewed by others who note that particularly in emerging economies and developing countries there is variability between drug batches, between generic and originator products, and impurities may be present.21

The cost differentials for identical products according to how they are accessed also indicates that legislation that is intended to regulate dispensing fees and the handling costs of medicines is also failing.22 Costs to the medical aid schemes were related to the available benefits; the higher the available benefit the greater the cost even for identical products. This is in accordance with published data.15

The cost of OTC products accessed by beneficiaries or recommended by pharmacists was higher than when prescribed by a doctor. This has been reported for Schedule 0 medicines in South Africa but to our knowledge has not been studied for S1 and S2 OTC medicines.23 Furthermore, non-dispensing doctors appeared to be more cost-effective than dispensing doctors, and network contracts between the medical aid schemes and doctors did not appear to generate OTC medicines savings. These findings accord with other local research.24,25

In some cases the cost differentials appeared to be related to provision of larger pack sizes by pharmacists and non-dispensing doctors (whose prescriptions are ultimately dispensed by pharmacists). Further investigation is required to assess the extent to which dispensed quantities might differ from what was prescribed. In this regard recent changes to legislation5 prevent the sale of large pack sizes, but this does not necessarily prevent pharmacists from dispensing multiple boxes of a smaller quantity. It is possible/likely that pharmacies have higher overhead costs than dispensing doctors, and that they dispense accordingly in order to maximise returns. While regulated by government,22 the variable application of dispensing fees may be a factor in the cost differentials. This was not measurable in this study.

Several ingredients within the S1,S2 category, for example ephedrine, pseudoephedrine and codeine are subject to legislative restrictions.6,7 In the ATC category under review, codeine is included in several products up to the specified maximum concentration. While codeine is a weak opioid, despite these safeguards the drug has the potential for abuse and dependence. Furthermore, sedation, and euphoria are common side effects that may impair function.26 Simply decreasing the codeine quantity accessible to an individual consumer is also not an effective control because in the medical aid schemes environment it is possible for one beneficiary to access additional OTC quantities by simply using another family member’s benefit. In fact, research has shown that in this country 43% of codeine abusers accessed codeine-containing products through their medical aid schemes.27 A recent investigative report has also highlighted poor oversight by government and poor compliance in the dispensing of codeine-containing products by pharmacists.28

Billions are spent annually on OTCs in South Africa, apparently not in a cost-effective manner. It is therefore appropriate to consider whether free market principles should prevail or interventions introduced that would better regulate access to and the cost and quality of OTCs. For the BP category, in order to reduce costs medical aid schemes could enhance managed care interventions, perhaps restrict access to lower cost products by following strategies such as the Maximum Medical Aid Price (MMAP)29 or a medical aid scheme-specific recommended price list that would only cover products at the lower end of the cost spectrum.30 Medical aid schemes could also do more to develop evidence-based OTC formularies and educate beneficiaries in the use thereof. Benefits could be restructured in order to create greater awareness of cost implications, although research has shown that “brand awareness” does not change in response to such initiatives.31 Alternatively, the benefit could be abolished completely, leaving beneficiaries to self-medicate according to affordability, but in this regard research has shown that while “price shopping” may be supported in theory, consumers are limited in their ability to effect change.32 In the DP category, medical aid schemes could pay more attention to the potential value of doctors, predominantly general practitioners but dispensing doctors in particular, who appear to be more aware of costs in their prescribing of OTCs to patients.

To a large extent managed care initiatives are in effect in the public sector through processes such as the State’s tender system (which manages the cost aspect) and formularies such as the EML (which restricts access to a limited range of products and also affects quality by excluding most multi-ingredient products).9 Extension of State control to the private sector’s access to OTC medicines would almost certainly impact on overall costs and quality through regulation in areas of pricing, product composition and polypharmacy. On the other hand, up-scheduling of an ingredient such as codeine would likely lead to an increase in costs through additional consultations with doctors and also financial disadvantage to pharmacies.33

The results of this analysis and the list of possible interventions should also be considered within the context of current debates around private sector healthcare in South Africa. Three documents are under consideration: the National Health Insurance (NHI) Bill, the interim report of the Health Market Inquiry (HMI), and the Medical Schemes Amendment (MSA) Bill.34–36 The NHI Bill is focused on the future, while the HMI report is directed towards the existing private healthcare system with an emphasis on the roles of private hospitals, medical aid schemes, administrators and doctors in driving the costs of private healthcare. Pharmaceutical companies, manufacturers and distributors of OTCs were not covered by the HMI, but recommendations in the interim report certainly apply and are consistent with the interventions proposed above based on results of the present study. These include the need to introduce value-based purchasing, effectively control costs, educate disempowered and uninformed medical aid scheme beneficiaries, and use DSPs with obligations to provide cost-effective quality healthcare.

The proposed amendments to the Medical Schemes Act include ten major changes of which two are particularly relevant to this study: revising the current acute benefit package to include primary health care (PHC) medicines and care, and ensuring that the comprehensive benefit package is covered in full without co-payments. In terms of OTCs, if the amendments become law then in future the medical aid schemes would likely include within the PHC benefit the common ATC categories and the poly-pharmaceuticals discussed in this paper. According to the NHI Bill these would then have to be covered in full with no co-payments. Without attention being given to access and cost controls, the lack of formularies, DSPs, networks and guaranteed prices, there is thus a risk that the proposed MSA amendments would actually result in higher expenditure on OTCs in the future.

Conclusion

Within the medical aid schemes industry, access to and costs of OTC medicines are poorly managed, whether by the beneficiaries, medical aid schemes/administrators, pharmacists or State. On the positive side, doctors (particularly doctors who dispense from their consulting rooms) show better cost containment compared to pharmacists, who appeared to favour more-expensive products in larger pack sizes. The recommendations emanating from this study are consistent with those that appeared in the recent interim report of the Health Market Inquiry,35 demonstrating that cost drivers that apply to hospitals, administrators and doctors apply similarly in the OTC market, with stakeholders endeavouring to drive costs up rather than down.
