Purpose: To assess the degree of satisfaction and expressed needs of pharmaceutical care services in patients with chronic diseases and explore the factors related to the needs from patients’ perspectives for the further development of pharmaceutical care service models.
Patients and methods: A cross-sectional survey of 220 patients (mean age ± SD: 61.3±13.1, male:female: 104:116) was conducted. The questionnaire was structured to measure patients’ degree of satisfaction and expressed needs using a 5-point Likert scale. Additionally, preferred duration, methods of service delivery, and willingness to pay were surveyed. Responses were analyzed using an ordinal regression method to predict factors that were related to pharmaceutical care services.
Results: Sixty-seven patients had experienced pharmaceutical care services. Their satisfaction levels were high in all categories; however, there were no significant differences between ­categories. The levels of expressed needs were similar among categories without significant differences. The preferred delivery method was a face-to-face conversation combined with being provided with written information (53.2%). The preferred duration was ≤10 min (70.5%). About 48% of the patients showed willingness to pay for the service. Education level and region influenced patients’ needs.
Conclusion: The satisfaction and needs of pharmaceutical care services was very positive; however, noticing only a third of patients experienced pharmaceutical care services, this may indicate a lack of awareness and less appreciation of pharmacists by patients. Details concerning patients’ awareness and the value of pharmaceutical care services require further investigation.

Keywords: pharmaceutical care service, satisfaction, needs, patient perspective

Introduction

Globally, human life expectancy is increasing at a rate of more than 3 years every 10 years, and there is a 5-year life expectancy increase from 2000 to 2015.1 In 2011, the healthy life expectancy of Koreans was 70.7 years. Unfortunately, it was found to be approximately 10 years shorter than the life expectancy at birth of 81.2 years. Koreans have been suffering from diseases for 10 years before their deaths. This was predicted to be due to chronic metabolic diseases and a need for a comprehensive management program.2 In 2015, the cause of death in Korea was 150.8 cases of malignant tumors, 55.6 cases of heart diseases, 48.0 cases of cerebral vascular diseases, 28.9 cases of pneumonia, 20.7 cases of diabetes, and 9.9 cases of hypertensive diseases based on a population of 100,000. The increase in chronic metabolic diseases continues and the socioeconomic burden for the treatment of these diseases is increasing.3

Unfortunately, this is also aligned with an increase in prescriptions, limited accessibility to health care professionals, unreliable operations and regulations, and health care costs. “Change” is the new normal for our health care environment. The health care system has shifted from episodic care to population health management and from volume- to value-based care. Efforts that deliver effective and equitable global health care are needed.

To confront the increasing burden of chronic disease management, effective and well-designed pharmaceutical care services (PCSs) require implementation.410 The role of pharmacists and their contribution have been emphasized in treating chronic metabolic diseases and preventing subsequent complications.410 There are many studies that measure the outcomes of PCSs globally; however, the results are not consistent.5,11,12 They may vary depending on the target patient population, the service setting, and even the questionnaires’ content. As pharmacists look for opportunities to develop and expand the scope of practice for PCSs, patients’ views on these issues must be understood. Patients’ demands for access to services will promote the initiatives of PCSs and accelerate the changes of successful PCSs’ implementation.

In South Korea, since the development of PCSs is at the beginning stages, patients’ degree of satisfaction in PCSs and how they should be developed requires analysis. Few studies have addressed patients’ satisfaction with pharmacy services in South Korea. Most studies were conducted with general patients at community pharmacies, and the results were contradictory.13,14

According to a review of literature, 20 out of 33 studies on the subject of pharmacy services in South Korea were about prescription dispensing services, three for PCS research, and two for health promotion services. It confirmed that the pharmacy’s reliance on prescription drugs was high, and at the same time, it showed PCSs and health promotion services had not yet been settled. On the other hand, the most studied subject of the pharmacy service was related to medication instruction, which showed that the most important and importantly recognized service in Korea is medication guidance.15 There are several examples of PCSs that are in the beginning stage. The Seoul city’s pharmacy association has started the SAFE pharmacy program as a model of the future pharmacy in 2013, and currently more than 200 pharmacies are selected as SAFE pharmacies. SAFE pharmacies have the purpose of making patients safe and healthy by managing their medical history, preventing suicide, and promoting smoking cessation.16,17 The activities of the SMART pharmacy in Busan focus on providing “S”afe drug information, “M”anagement of personal health care, “A”ccurate disease information, “R”eliable, trustworthy pharmacy, “T”eaching for prevention and management of cardiovascular diseases, but no clinical outcomes have been published yet.18

On one side, the major barriers to internationally recognized Good Pharmacy Practice (GPP) standards compliance in community pharmacies in Korea were lack of time and labor, lack of updated clinical information, negative feedback or refusals from prescribers. There were significant differences according to the number of pharmacists and acceptability of the proposed GPP standards. Among these obstacles, the shortage of pharmacists issue cannot be resolved without changes in the pharmacy management environment, as pharmacists should be able to secure the manpower to spend more time on business processes.19

Elucidating health care consumers’ needs is the primary step to the successful implementation of PCSs. Therefore, we conducted a cross-sectional survey of patients with chronic metabolic diseases to investigate their perceptions of PCSs by questioning their satisfaction and expressed needs. Further, we assessed patients’ characteristics related to the expressed PCSs needs.

This study was approved by the Institutional Review Board of Seoul National University (IRB number 1401/001-013). Written consent was obtained from respondents prior to participation. This study was conducted in accordance with the Declaration of Helsinki.

Material and methods

Selecting target diseases and stakeholders for PCSs

Analytic Hierarchy Process was conducted to select target diseases which we intended to use to develop the PCS model.20 In this process, the seven chronic metabolic diseases were selected from eleven which indicated as being most likely to place a high demand on PCSs by both the Ministry of Health & Welfare of South Korea and the Korean National Health & Nutrition Examination Survey (in press). In addition, through stakeholder mapping techniques, we found the main consumers of PCSs should be health care providers, pharmacists, and patients. We previously published the qualitative analyses of the PCS needs by health care providers and this study focused on PCSs with patients’ perspectives.21

Developing survey questionnaire

We aimed to investigate current knowledge, attitude, and practice of PCSs perceived by patients through this qualitative survey. A questionnaire was preformulated by facts clustering, opportunity web, and mind map processes so that various matrices of PCSs could be completed.21 The prototype questionnaire had consisted of eleven satisfaction and eleven expressed needs. We held focus group discussions with clinical pharmacists with PCSs experiences and pharmacy school faculties, and conducted focused individual interviews with physician specialists and registered nurses. A pretest was performed on seven laymen. The experts and the pretest participants were asked to provide feedback on any aspects – whether the questionnaire covered the full range of subjects to be investigated and whether the details were appropriate. We modified the survey including style, length, and difficulty on completing and attached supplementary pictures to improve understanding. The items that did not achieve content validity index of 80% were deleted. Through these modifications, seven satisfaction and six needs questions were finalized. Factor analysis was performed on PCSs needs and nearly all items were ranging from 0.64 to 0.78. The internal consistency reliability with Cronbach’s α for the six questions about PCSs needs was 0.81.

The survey questionnaire consisted of three parts. Part 1 measured patients’ satisfaction levels on seven detailed service items: “medication reconciliation”, “duplication or interactions”, “inpatient drug use review”, “medication changes”, “storage and instructions to use”, “lifestyle modification”, and “adherence”. Satisfaction was measured only in patients who indicated previously receiving each service. Part 2 measured patients’ expressed needs on six items: “medication reconciliation”, “medication changes”, “patient-customized services”, “drug and health information”, “over-the-counter (OTC) drugs and supplements”, and “adherence tools”. Part 3 measured preferred duration, delivery methods of PCSs, and willingness to pay the fee for PCSs. Each question in Parts 1 and 2 was measured using a 5-point Likert scale: “1”=least agree to “5”=most agree. Part 3 consisted of multiple-choice questions (Table 1).

Study setting and survey interview

The survey was conducted between March and May 2014. Inclusion criteria comprised patients who had chronic diseases and three or more hospital visits within the past year. Patients were excluded if they had health professionals in their family, were not taking any medications, or if they had a medical condition that limited their ability to recall or provide information on the survey. The survey was performed in four different regions of South Korea: Seoul, Gyeonggi-do located in the northwestern area, Busan located in the southern area, and Gyeongsang-do located in the southeastern area. Pharmacies were selected according to location and size, which would be important factors when patients choose a pharmacy. They were medium to large sized with 4–7 staff and near the hospital entrance. The target group of patients had regular visits to the pharmacies to fill prescriptions. The surveys were administered after informed, written consent was obtained. Each survey took approximately 20–30 minutes. An interviewer assisted the patient to respond to each question from the beginning to the end of the questionnaire 1:1 to assist with readability and completion rate. The interviewers were trained prior to the survey implementation to minimize interinterviewer variability and maximize the collection of responses. The main content of the training was communication techniques with patients and medication therapies for chronic diseases.

Statistical analysis

We collected and organized the questionnaire data with MS Excel 2016 (Microsoft Corporation, Redmond, WA, USA). SPSS version 23 (IBM Corporation, Armonk, NY, USA) was utilized to analyze the data. Univariate analyses were conducted to describe patients’ baseline characteristics. Descriptive statistics were calculated to present the frequencies of the survey responses. Statistical differences of each degree of both satisfaction and needs for the PCSs were tested using an analysis of variance. An ordinal logistic regression was used as the dependent variable to determine the unadjusted ORs and calculate the factors that predicted patients’ needs. We considered P-values less than 0.05 as statistically significant.

Results

Participants’ demographics

Participants’ characteristics are shown in Table 2. A total of 220 patients (mean age: 61.3±13.1 years old, male: 47.3%) completed the survey questionnaire. One hundred and twenty-six patients (57.2%) had ≥2 chronic diseases, and 85 patients (38.6%) were taking ≥6 medications per day.

Table 2 Patients’ baseline characteristics (n=220)

Satisfaction with PCSs

Participants’ satisfaction with PCSs is described in Table 3. Only 30.5% (n=67 of 220) of patients received at least one PCS. Among 67, the patients received a lifestyle modification service and medication changes service (n=35) which had the most number of responses, and the least number of response was 6.6% (n=11) of an adherence service. There was a significant difference among the numbers of responses (P<0.001); however, no significant differences in the degree of satisfaction among PCSs items were observed.

Duration of provision, method of delivery, and willingness to pay for PCSs

Participants’ wishes concerning duration, delivery methods, and willingness to pay for PCSs are shown in Table 5. The preferred duration of PCSs was ≤10 min (n=155, 70.5%). The preferred delivery method was oral counseling with giving out written information at the first encounter (n=117, 53.2%). Approximately 48% of patients (n=106) showed willingness to pay for PCSs, and 21.3% (n=47) responded “undecided”.

Factors related to the expressed needs of PCSs

Medication reconciliation service

“Medication reconciliation” service was significantly associated with high school graduates (OR 1.87; 95% CI 1.01–3.46) when compared to the middle school graduates or less. A similar result was observed with patients who received the service in Seoul and its vicinity (OR 2.36; 95% CI 1.42–3.92) compared to those who received the service in local areas. Moreover, patients who took 3–5 medications demanded the service approximately 2.8 times more compared to those who took 1–2 medications (Table 6).

Medication changes

“Medication changes” service had a significant association with age (≥65 years old, OR 0.57; 95% CI 0.35–0.95), education (high school graduates, OR 1.93; 95% CI 1.02–3.63, college graduate or higher, OR 2.17; 95% CI 1.19–3.99), location (Seoul and its vicinity, OR 2.20; 95% CI 1.31–3.70), and the number of chronic diseases (two chronic diseases, OR 0.34; 95% CI 0.18–0.63; ≥3 chronic diseases, OR 0.48; 95% CI 0.24–0.94) when compared to each reference (Table 7).

OTC drugs and supplements service

“OTC drugs and supplements” service showed a significant inverse association with age (≥65 years old, OR 0.59; 95% CI 0.36–0.98) and more than two chronic diseases (OR 0.55; 95% CI 0.30–0.99). Patients who had an education level of college or higher (OR 1.84; 95% CI 1.01–3.36) and who received the services in Seoul and its vicinity (OR 1.94; 95% CI 1.15–3.26) demanded significantly more services compared to patients in the reference groups (Table 8).

Discussion

Despite the recent recognition of the benefits of PCSs, its implementation in patient care settings to achieve quality service remains a challenge.5,6,12,2224 Knowing that one of the major stakeholders of PCSs is the patient, patients’ awareness and demands of the service should be reflected to develop such services.

In this study, we found that only one third of patients experienced at least one service, which showed that PCSs were not generally available or at least recognized among patients. But their satisfaction scores were high (ie, more than 4 points in all items); since the number of patients this applied to was low, more information is needed to generalize these results.

Moreover, we found that patients anticipated various PCSs throughout the treatment process. In a previous study, a telephone survey was conducted regarding patients’ demand of the services by hospital pharmacists to help medication management.25 It revealed that most respondents, in addition to general health maintenance, expected to receive information about indication, dosage, directions to use, adverse reactions, and drug interactions of not only prescription medications including postdischarge medications but also nonprescription medications. Moreover, patients were unaware of the roles or activities as suggested by the fact that patients incorrectly assumed some of the pharmacy services were not linked with hospital pharmacies. Another study showed that 83.0% of patients who recalled meeting a pharmacist during admission were satisfied with the encounter; however, only 7.7% were related to pharmacy services.26

This finding can be similarly applied to our results. Paradoxically, patients’ high satisfaction scores in this study may have been related to a low expectation of pharmacists. Like in other studies, our patients were not familiar with pharmacists’ services or the range of pharmacists’ activities.26,27 The public should be educated on pharmacy services before developing PCSs so that patients’ preferred needs can be reflected in the proposed details.

Patients with higher education levels showed high interest in “medication reconciliation”, “medication changes”, and “OTC drugs and supplements”. This could reflect their intellectual curiosity and awareness of the potential benefits from the medications. Ironically, older patients and patients with more chronic diseases showed less demand for “medication changes” and “OTC drugs and supplements”. We also found that patients who received services in Seoul tended to express a greater demand for PCSs, which might be due to frequent exposures in a medication-rich environment.27 This information can be applied to define the target group when developing PCSs and health care policies.

Direct delivery (ie, face-to-face) of PCSs was favored over indirect delivery methods (ie, email, text, or social networking). Patients may feel uncomfortable using indirect delivery methods; however, for the face-to-face method, the service time and place for private conversations should be considered to be standardized because local pharmacies in South Korea still focus on dispensing rather than facilitating PCSs for patients.

In our study, participants’ willingness to pay was low (48%) although we had 21% undecided. Some studies reported that 60–70% of the population was willing to pay for cognitive pharmacy services.2831 Other studies showed that the better the financial condition of patients or the lower the out-of-pocket cost, the more willing people are to pay for pharmacists’ services.29,31 Future studies should examine it considering patients’ health insurance and financial condition.

Study limitations

First, the survey questionnaire was adapted based on a panel of pharmacy experts to avoid possible sources of errors and bias in the survey. The experts included pharmacy school faculty members, board-certified pharmacotherapy specialists from the American College of Clinical Pharmacy, clinical pharmacists, nurses, and physicians. Despite the fact that our survey was designed as a qualitative survey to discover the patients’ acceptance status and perception of PCSs in South Korea, the content and construct validity and reliability were confirmed to be acceptable. Moreover, the format was introduced in accordance with the PCSs guidelines by the American Society of Health-System Pharmacists.32 Nevertheless, validation with more data is warranted in the near future. Second, patients were not aware of the previous services, thus causing difficulties in assessing the recall of PCSs. Third, the satisfaction with PCSs should be considered for the personnel factors and facility environment in the pharmacy, but these factors were not included in this study. In South Korea, technicians are not allowed to assist with dispensing work. Further research is needed on the various human and institutional factors for patients to be satisfied with their PCSs.

Despite the limitations, we believe that our findings offer valuable information to understand patients’ recognition and need for PCSs. It also provides insight to overcome the lack of articulated standards for pharmacists’ services and further initial data for developing a PCS model, especially in countries in the preliminary stages of PCSs development and standardization, including South Korea.

Conclusion

The overall satisfaction and expressed needs of the desired pharmacy services were high. Age, education, region, and number of chronic diseases affected patients’ expressed needs for PCSs; however, our data emphasized that patients seemed to be unaware of the diversity of services offered by pharmacists. Future efforts should establish lists of the roles of pharmacists and develop standardized PCSs for target diseases.
