Abstract

In order for the global healthcare system to remain sustainable, healthcare spending needs to be reduced, and self-treating certain conditions under the guidance of a pharmacist provides a means of accomplishing this goal. This article was developed to describe global healthcare trends affecting self-care with a specific focus on the role of the pharmacist in facilitating over-the-counter (OTC) medication management. Potential healthcare-related economic benefits associated with the self-care model are outlined. The importance of the collaboration between healthcare providers (HCPs), including specialists, primary care providers, and pharmacists, is also discussed. The evolving role of the pharmacist is examined and recommendations are provided for ways to successfully engage with other HCPs and consumers to optimize the pharmacist’s unique qualifications and accessibility in the community. Using the management of frequent heartburn with an OTC proton-pump inhibitor as a model, the critical role of the pharmacist in patient self-treatment of certain symptoms will be discussed based on the World Gastroenterology Organization’s recently published guidelines for the community-based management of common gastrointestinal symptoms. As the global healthcare system continues to evolve, self-care is expected to have an increasing role in treating certain minor ailments, and pharmacists are at the forefront of these changes. Pharmacists can guide individuals in making healthy lifestyle choices, recommend appropriate OTC medications, and educate consumers about when they should consult a physician.

Introduction

The global healthcare system is expected to undergo significant changes in the coming decades to remain economically viable, and self-care and self-medication will likely become important for driving these changes. The authors, who provided the concept and developed the content for this review, are experts in the area of self-care and describe the various and related aspects of this treatment model, as well as the role of self-care in the future of the global healthcare system.

John Bell, AM, BPharm, FPS, FRPharmS, FACPP, MSHP, the Principal Advisor to the Pharmaceutical Society of Australia’s Self-Care Program, has authored Importance of Self-Care in the Future of Quality Affordable Medicine in the Twenty First Century, which defines self-care and describes its key stakeholders and components, including the importance of enhancing health literacy. The potential financial savings of shifting from physician-based care to self-care is also discussed. Additionally, Mr. Bell discusses The Role of the Pharmacist in Self-Care: A Prescription for the Future. Because pharmacists are ideally placed to provide healthcare advice, the pharmacist’s role as healthcare provider (HCP) will continue to expand. Pharmacists not only fill prescriptions but also educate consumers about the importance of healthy lifestyle choices, recommend over-the-counter (OTC) treatments, perform medication monitoring, and refer consumers to physicians as necessary.

Gerald Dziekan, MD, MSc, is the Director General of the World Self-Medication Industry whose section Why Self-Care? A Public Health and Health Economic Perspective on the Benefits of Self-Care describes ways that self-care, and in particular, self-medication, can positively affect public health and reduce the economic burden of managing minor ailments and some chronic conditions by shifting care to the consumer with guidance from pharmacists and physicians.

Varocha Mahachai, MD, FRCP, is the Director of the Gastrointestinal & Liver Center for Bangkok Medical Center and Professor at Chulalongkorn University. Her section, Reflux and Heartburn as a Self-Care Model, describes the number of OTC treatments available for treating acid reflux-related symptoms, including recent switches of proton-pump inhibitors (PPIs) from prescription to OTC. With these readily available treatments, pharmacists can help consumers effectively and safely manage their acid reflux-related symptoms. Pharmacists can also help limit the risk for heartburn treatments masking more serious underlying conditions.

Within different sections, this article describes factors affecting the global healthcare system, and through examples such as the increasing availability of OTC PPIs also describes the roles that self-care and pharmacists can play in sustaining the economic viability of that system by shifting a portion of the costs for caring for some minor ailments to consumers.

This article is based on previously conducted studies and does not involve any new studies of human or animal subjects performed by any of the authors.

Importance of Self-Care in the Future of Quality Affordable Medicine in the Twenty First Century

Self-care is characterized by healthcare consumers who take proactive roles in identifying and managing their health conditions to optimize their overall physical health and psychological and spiritual well-being [1, 2]. Self-care has been described as existing on a continuum, with purely self-initiated activities such as preventative healthy lifestyle choices on one end and treatment for acute minor ailments and maintenance therapy for certain chronic conditions on the other (Fig. 1) [1, 3, 4]. Effective self-care requires active collaboration between consumers and HCPs, including pharmacists, and is reliant on well-informed consumers and HCPs with effective communication skills [5]. Consumers are supportive of the concept of self-care, which they view as an essential feature of their healthcare, yet few consumers are confident that they can effectively manage their own health [5].

Webber et al. [6] describe several key domains and behaviors of self-care. Health literacy is a key component of self-care and is broadly defined as an individual’s ability to acquire and understand information related to their healthcare. Self-care is also reliant on an individual’s awareness of their physical and mental health, including awareness of their current health status (e.g., body mass index, cholesterol, blood pressure), which requires receiving regular health screenings. Self-care also involves engaging in regular physical activity, such as moderate levels of exercise (e.g., walking, cycling), eating a healthy, nutritious diet with appropriate caloric intake, and having good hygiene, including proper dental care. In addition, effective self-care involves avoiding and mitigating potential health risks, such as eliminating tobacco use, limiting alcohol consumption, and receiving vaccinations, as well as using products, services, diagnostics, and medicines rationally and responsibly. These authors suggest that identifying domains where an individual is lacking can allow for developing a personalized self-care index that addresses potential deficits in self-care with an action plan, including identifying areas where guidance (e.g., from an HCP) is necessary.

Self-care is reliant on enhancing consumers’ health literacy to ensure that they can process the health-related information that they obtain on their own or from HCPs and allow for making informed healthcare decisions [5, 7]. Limited health literacy is common, particularly in those who are older, from lower socioeconomic strata, and with limited education [7]. Estimates in the United States suggest that 36% of the adult population has basic or below basic health literacy, while in Australia it has been estimated that approximately 60% of the population has below the minimum health literacy necessary to meet the demands of everyday life and work “in the emerging knowledge-based economy” [8, 9]. The consequences of poor health literacy include an inability to communicate needs to HCPs, a limited ability to understand instructions for taking prescription medicines, higher hospitalization rates, and, implicitly, higher healthcare costs [7].

Self-care can contribute substantially to easing financial pressures on the healthcare system by shifting the cost of care for some relevant conditions from physicians to consumers while also enhancing healthcare outcomes [3, 10]. Empowering pharmacists and establishing community pharmacies that serve as cost-effective resource centers for providing authoritative, objective, evidence-based information/advice and directions for the appropriate use of various treatments is a goal of self-care that is of interest to consumers [11, 12, 13]. Pharmacists have a necessary role in screening for certain conditions, making self-care treatment recommendations, and/or providing referral support as needed. Programs have been implemented to meet this goal, including the Health Destination Pharmacy program in Australia, which seeks to position pharmacists as primary HCPs who emphasize self-care [13]. A study of participants in this program reported benefits for the pharmacy as a whole as well as for consumers despite a minority of pharmacies experiencing negative financial growth during the study period. The Global Respiratory Infection Partnership is another example of providing appropriate self-care information and advice through HCPs, including pharmacists, for managing upper respiratory tract infections (e.g., coughs, colds) without the use of antibiotics [14]. With the increasing incidence of antimicrobial resistance, pharmacists can play a role in advocating antibiotic stewardship by promoting use of self-care treatment options. These initiatives suggest that the expanding role of pharmacists as HCPs, particularly within the realm of self-care, can enhance outcomes and reduce the cost and resource burden on the healthcare system.

The Role of the Pharmacist in Self-Care: A Prescription for the Future

HCPs, in particular general practitioners (GPs), continue to be the primary source for treating minor ailments [5]. A study conducted in the United Kingdom (UK) reported that 13% of GP and 5% of emergency department (ED) hours were spent on consulting for minor ailments that could be managed in a community pharmacy setting [15]. In addition to managing certain chronic conditions, self-care, including self-medication, can help to shift the burden of treating these minor ailments from GPs to other HCPs, particularly pharmacists, and consumers themselves (Fig. 2) [3]. Pharmacists, a widely available and conveniently accessible healthcare resource [16], are ideally placed to meet the challenges of ever-evolving consumer needs and global healthcare systems [12]. In addition to supplying treatments prescribed by physicians, pharmacists can serve as integral partners in a collaborative care team of HCPs [3, 12]. Pharmacists are also involved with health promotion by screening for, and increasing the awareness of, certain conditions and discussing strategies such as making healthy lifestyle choices for preventing certain health issues [12].

Self-medication is a key component of self-care [17]. Pharmacists provide valuable information to ensure that consumers receive treatments that are appropriate for a given condition [12]. Importantly, consumers view pharmacists as trusted resources for providing information about their healthcare [18]. When selecting a non-prescription medicine, consumers report that the advice of a pharmacist is one of the most important factors in making their decision (Fig. 3) [18]. Although pharmacists can be the first point of contact for some healthcare consumers, they are a relatively underutilized resource [5].

The potential benefits of consulting a pharmacist in the first instance include more immediate access versus having to wait for a GP appointment, as well as reducing travel time and healthcare-related costs [19]. Additionally, in many cases non-prescription/OTC products are less expensive than prescription medications [19], and as mentioned previously, the pharmacist is well positioned to refer consumers to a physician when symptoms indicate a potentially serious condition. A study conducted in the UK has demonstrated that individuals seeking treatment for minor ailments from an ED, a GP, or a community pharmacy had comparable symptomatic and quality-of-life outcomes [20]. However, the costs associated with receiving a consultation in the pharmacy setting were significantly lower than in the ED or GP setting. The key factors associated with selecting a point of care were location and convenience and prior experience with and perceived severity of the symptom that necessitated seeking treatment from an HCP. Some individuals presenting in the pharmacy setting had previously experienced the symptoms, as indicated by their often direct request for a specific treatment. In contrast, the majority of those seeking care from an ED were experiencing the symptom for the first time and the symptoms were perceived to be more severe. This effect may have confounded the cost analyses, but these data provide insights into the types of conditions that consumers are likely to self-treat in the pharmacy setting. A chronological review of policy changes in the UK suggested that continuing to reclassify medications used and providing free access to an HCP and free or low-cost treatment for minor ailments will further ease the burden of treating minor ailments in the GP setting while increasing access to healthcare services [21].

Utilizing self-care can enhance patients’ confidence by improving their skill set and empowering them to treat certain conditions on their own instead of always relying on an HCP [19]. For certain conditions, a collaborative care model where the individual is first diagnosed by a physician who provides an initial treatment plan is most appropriate [3]. After the initial diagnosis, the pharmacist is responsible for educating the consumer on identifying signs and symptoms of recurrence and ways to effectively self-treat these recurrences, as well as identifying circumstances when it is necessary to consult a physician again, for instance if symptom severity increases [22]. Pharmacists are also ideally placed to monitor for possible interactions between the multiple treatments that an individual may be receiving, as well as to inform consumers about the potential adverse events associated with a given treatment [22].

Despite these benefits, there are some potential concerns about self-medication, including the potential for consumers to inappropriately use the treatment that is recommended [23]. There is also the concern that some symptoms perceived to be minor may be the result of an undetected more serious condition that was not appropriately identified [23]. It is, therefore, important that undergraduate and postgraduate pharmacist training involves ways of enhancing clinical decision-making skills, which, as indicated by a survey of Canadian pharmacists, are often lacking [24].

Consumers are assuming greater autonomy in their healthcare, which could increase the healthcare system’s efficiency [5]. These emerging trends lend themselves to a greater role for self-care and expanding the role of community pharmacies. In the future, it is most likely pharmacies and pharmacists will not only be providing prescription and non-prescription medications, but will also be involved with more complex interventions. Assisting with self-care and self-medication is essential as the role of the pharmacist continues to evolve to meet the demands of the healthcare system and to ensure they are providing a unique, value-added service.

Why Self-Care? A Public Health and Health Economic Perspective on the Benefits of Self-Care

The aging global population [25], increasing incidence and burden of non-communicable diseases (NCDs), and other societal changes (e.g., globalization) [26] have led to increases in healthcare spending [26, 27], which can outpace the growth in gross domestic product [27]. NCDs, including potentially preventable conditions such as cardiovascular disease, respiratory disorders, cancer, and diabetes, are associated with significant disease burden and have become the leading causes of global mortality [26]. Compounding the pressure on the healthcare system, the number of workers per retiree is decreasing, particularly in emerging markets [28].

Traditional healthcare models characterize consumers as limitedly involved, passive recipients, but a shift toward empowering patients and consumers by increasing health literacy to enhance their participation is occurring [5, 29]. Advice from HCPs continues to be an important source of health-related information, but consumers often seek out information on their own, commonly through on-line resources [30], which can increase their ability to recognize symptoms/conditions suitable for self-care. Mobile technologies are becoming increasingly relevant to self-care by offering new consumer education opportunities that can reach into developing countries further and more cost effectively than healthcare infrastructures can [26, 31]. Importantly, consumers who are the most confident in making healthcare decisions have healthcare costs that are 8–21% lower than those who are the least confident [29].

The various stakeholders involved in self-care have complementary roles that must be evaluated from their various perspectives. The pharmaceutical industry is needed to develop safe and effective treatments, to identify appropriate prescription-to-OTC switch candidates, and to educate HCPs and consumers. Governmental agencies are needed to establish appropriate regulations and foster partnerships between HCPs and consumers (e.g., through public health campaigns, enhancing self-care initiatives). Appropriate regulatory frameworks are needed to empower consumers, provide access to safe and effective treatments, promote pharmacists’ roles, and enhance access to OTC products (e.g., by providing tax deductions, switching appropriate treatments from prescription to OTC status). HCPs help consumers recognize symptoms and identify appropriate self-care options, including the use of OTC products. More than 80% of physicians agree that responsible use of OTC products can reduce the burden on the healthcare system and effectively manage minor ailments [32]. Pharmacists have an important role in self-care, particularly self-medication, by serving as a point of access for providing treatment advice or HCP referrals as necessary. In the UK, a study of community pharmacy users seeking care for flu-like symptoms assessed consumer preferences for pharmacy services based on their willingness to pay. Respondents reported a willingness to pay £38 to receive care in a pharmacy setting versus no treatment [33]. However, the quality of care that was provided had an effect on their willingness to pay, as indicated by their unwillingness to pay for care at the lowest-quality pharmacies. The characteristics that differentiated high- from low-quality pharmacies included whether a friendly, trained pharmacy staff member provided a better understanding of the nature of symptoms and how to effectively manage them. Additionally, as has been previously reported, the convenience of accessing the pharmacy was an important factor, as was whether it was local or physician-affiliated versus being located in a shopping center.

Self-care can benefit individuals, healthcare systems, and, as such, society as a whole. The HCP’s role is evolving toward partnering with empowered consumers who are confident in making healthcare decisions. Self-care not only provides an opportunity to relieve overburdened healthcare systems, but also empowers patients and consumers and allows them to more effectively manage their conditions and improve health outcomes and quality of life [5]. Effective use of OTC products can eliminate the stress and inconvenience of HCP visits, saving time and money. In particular, evidence is growing that supports the value OTC products add to the global healthcare system. In addition to reducing costs associated with unnecessary HCP visits, self-care and the use of OTC products can enhance health outcomes and reduce lost work productivity (Table 1) [10, 34]. For example, in the European Union, the estimated annual savings from shifting 5% of care to self-medication is over €16 billion [3]. Although these studies report estimated costs based on hypothetical models, they indicate that there is the potential for substantial healthcare cost savings from enhancing the self-care options that are available to consumers.

Reflux and Heartburn as a Self-Care Model

Heartburn is a common recurrent gastroesophageal symptom marked by a burning sensation that develops behind the sternum and radiates up toward the neck, which may be accompanied by regurgitation of stomach contents (e.g., acid, food) into the mouth [35]. These symptoms most commonly occur after meals, during exercise, and while lying recumbently, particularly at night. Approximately 10–20% of individuals in Western countries experience these symptoms at least weekly, while in Asian countries the prevalence is often less than 5% [36]. The degree of impairment, including symptom frequency and severity, distinguishes frequent heartburn from gastroesophageal reflux disease [36]. However, frequently occurring symptoms of heartburn and regurgitation can negatively impact the affected individual’s quality of life [35].

The World Gastroenterology Organization Global Guidelines for community-based management of common gastrointestinal symptoms provide resource-sensitive treatment recommendations based on the point of care [35]. According to these guidelines, the primary goal for self-treating frequent heartburn is complete symptomatic relief and restoring quality of life. Self-care treatment options for heartburn and/or regurgitation include lifestyle and behavioral modifications such as weight loss and limitations on the consumption of foods/beverages and/or medications that may exacerbate symptoms. OTC treatment options, such as antacids, alginates, H2 receptor antagonists (H2RAs), and PPIs, are also recommended based on the frequency and intensity of heartburn and regurgitation symptoms. Antacids, alginates, and lower- and higher-dose OTC H2RAs are appropriate for infrequent, mild, or moderate symptoms, while OTC PPIs are appropriate for frequent symptoms that occur ≥2 days/week. Regardless of the frequency and intensity of symptoms, all individuals with heartburn should be instructed to include lifestyle/behavioral modifications as adjunctive therapies to these pharmacologic treatments.

A treatment algorithm that was developed for managing individuals presenting in the pharmacy setting with self-diagnosed reflux symptoms describes the circumstances that warrant referral to a physician [37]. Individuals presenting with alarm features, including new symptom onset at over 50 years of age, painful or difficult swallowing, gastrointestinal bleeding, laryngitis, unexplained weight loss, and cardiac-type chest pain, should be referred to a physician [35, 37]. Additionally, individuals who do not adequately respond to a 2-week course of OTC PPI therapy and those who experience a recurrence of symptoms within 3 months of stopping a 2-week course of OTC PPI therapy should be referred.

The relatively high prevalence of uncomplicated frequent heartburn and the availability of highly effective OTC treatment options make managing these symptoms in a physician’s office inefficient in terms of cost and resource utilization [37]. Pharmacists are, therefore, ideally positioned to serve as frontline HCPs with an important role in identifying consumers who are suitable for self-treating their heartburn. Additionally, pharmacists can reinforce directions provided by the product labelling and communicate that a failure to respond to treatment requires a physician consultation. Frequent heartburn has few direct long-term consequences, but it is important to identify those with a high likelihood of having a serious underlying condition to manage these symptoms effectively and safely [35, 37]. Additionally, although there are potential safety concerns associated with the long-term use of PPIs, instances are rare in this population and most individuals experiencing frequent heartburn will not require extended periods of treatment [35, 37].

Conclusion

Shifting care for certain conditions from physicians to other HCPs, including pharmacists, and consumers can help to alleviate the increasing burden on the healthcare system by reducing costs and resource utilization. Self-care and self-medication are expected to be important aspects of the evolving global healthcare system that will seek to manage these issues.

Self-care functions most efficiently when the various stakeholders collaborate to serve consumers’ needs by providing appropriate guidance and empowering their decision-making processes. Pharmacists, therefore, play a critical role in helping consumers manage minor ailments without relying on costly and time-consuming physician visits for conditions that can be self-managed. Additional stakeholders, including the pharmaceutical industry and governmental agencies, help to ensure that safe and effective self-care treatment options are available.

Heartburn and regurgitation is a prime example of a generally mild condition that is ideal for self-care. Lifestyle modifications and numerous OTC treatment options are available that have been shown to be safe and effective. Pharmacists can be expected to play a key role in educating consumers about the proper use of these products, including, for instance, following label instructions and consulting a physician if symptoms recur at the end of the assigned treatment period or if other alarm features appear.
