Knowledge, attitude and practice of pharmacists on medication therapy management: a survey in Hospital Pulau Pinang, Penang, Malaysia
Journal of Pharmaceutical Health Care and Sciencesvolume 5, Article number: 1 (2019)
Medication therapy management (MTM) service provides set of clinical activities to optimize therapeutic outcomes for patients. It requires the collaboration between patient, pharmacist and other healthcare providers to ensure safe and effective use of medicines. The objective of the current study was to assess Hospital Pulau Pinang pharmacists’ knowledge, attitude and practice on MTM service.
A self-administrated validated survey was carried out among all pharmacists working at Hospital Pulau Pinang.
A total of 93 pharmacists out of 130 (71.5%) were included in the study (61.3% between the age of 20–30 years old, 74.2% female, 68.8% Chinese, 88.2% holding bachelor’s degree and 48.4% working in medication therapy adherence clinic and outpatient pharmacy). Majority of pharmacists had a high level of knowledge and positive attitudes regarding MTM service. All pharmacists agreed that MTM service could improve the quality of health services and most pharmacists were interested in providing MTM service (92.5%). Moreover, 95.7% were interested in acquiring more information about MTM service. About the barriers that might affect MTM service implementation, the most common barriers identified by pharmacists were lack of training (88.2%), need of high budget to implement MTM service (51.6%) and lack of time (46.2%).
Overall, the research findings provide some insights about the Hospital Pulau Pinang pharmacists’ knowledge, attitude and practice regarding MTM service. Majority of pharmacists agreed and showed their interest towards the implementation of MTM service.
Medication therapy management (MTM) service is defined as a service or group of services that optimize therapeutic outcomes for individual patients [1, 2]. It requires the collaboration between patient, pharmacist, physician and other healthcare providers to control patient’s condition, prevent drug related problems and ensure safe and effective use of medicines to reach patient’s therapy outcomes [3, 4].
In 2003, MTM service was included in Medicare Modernization Act (MMA), United States America (USA), and that was the initial step to start applying MTM service at different healthcare sectors. MMA identified the importance of implementing MTM service to achieve three different goals: enhance patients’ adherence to their medications, give optimal education and counselling to patients regarding their drug therapies and detect any adverse drug reaction associated with the therapy. These goals could be achieved when pharmacists work with physicians and other healthcare professionals to optimize medications use according to national and international guidelines .
American Pharmacists Association (APhA) and National Association of Chain Drug Stores Foundation (NACDS) descried five main elements of MTM service including: Medication Therapy Review (MTR), Personal Medication Record (PMR), Medication Related Action Plan (MAP), Intervention or Referral and Documentation and Follow-Up. These five elements are needed to implement MTM service in pharmacy practice .
MTM service can be also sorted into levels to make performing of this service more scalable and applicable. There are three levels of MTM service. First level is Adherence Management, and this is the lowest level. In this level pharmacists ensure that patients are adhering to the medications that they take for certain type of disease such as; hypertension, diabetes or dyslipidemia. Pharmacists need general clinical knowledge to apply this level. The importance of Adherence Management is to enhance health outcomes and reduce costs linked to lack of adherence. The second level is Interventions on Drug-Related Problems. In this level pharmacists apply Medication Therapy Review Service (MTRS) to ensure safe and effective use of all medications that are used by patients. There are two types of MTRS: Comprehensive and Targeted. In Comprehensive type, pharmacists review all medications taken by patients including prescribed, non-prescribed, over the counter and herbal medications. Then pharmacists detect if there is any problem associated with these medications and try to resolve it. In Targeted MTRS, pharmacists assess specific actual drug related problem. This happens after providing comprehensive service first, so pharmacists already have information about all medications taken by patients. The third and highest level of MTM service is Disease State Management Service. In this level pharmacists cover all chronic diseases that patient is diagnosed with. Pharmacists participate not only in drug related problem interventions, but also in non-drug therapy, lifestyle modifications and other activities that optimize health outcomes .
In Malaysia, Ministry of Health (MOH) established medication therapy adherence clinic (MTAC) in 2004 to be the first pharmacist-managed clinic in Malaysia. MTAC was implemented to enhance patients’ adherence to their medications. Over the past years, many types of MTACs has been introduced and covered many diseases and conditions such as; diabetes, stroke and respiratory disease. In 2013, thirteen types of MTACs were established by MOH with 660 different facilities offering the service around Malaysia [8,9,10].
The main difference between MTM service and MTAC is that MTAC focuses mainly about adherence. The main objective of this service is to improve patients’ understanding of medicines taken by them. On the other hand, MTM service includes furthermore services such as; detection of any adverse drug reaction associated with the therapy taken by the patient and disease state management [7, 10].
Aims of the study
Assess the level of knowledge, attitude and practice (KAP) of medication therapy management service among pharmacists working in Hospital Pulau Pinang.
Identify various challenges and barriers towards providing MTM service in the future.
Study setting and design
This study was a cross-sectional survey of medication therapy management service KAP and was carried out at Hospital Pulau Pinang. Questionnaires were distributed among all pharmacists that were working at the hospital during research period, between March 2018 and July 2018.
A convenience sample of 130 pharmacists was included in the study. All trainee pharmacists and those who were on leave during research period were excluded.
Development of questionnaire
After referring to many studies regarding MTM service in the literature, a structured questionnaire was designed to cover all the main key points of the research and in a way that suit with local population of Penang. Later, the questionnaire was validated by six lecturers from the discipline of clinical pharmacy at Universiti Sains Malaysia and it was examined for content relevance and appropriateness. Minor modifications were done based on their comments. Moreover, face validity was done by giving the questionnaire to a group of five pharmacists working at Hospital Pulau Pinang. Then the final structure of the questionnaire was conducted based on all comments given by participants. Finally, for reliability, a pilot study was done on 15 pharmacists working at Hospital Pulau Pinang. The pharmacists who were participated in pilot study have been excluded from final analysis. The survey was written in English and contains 34 items of questionnaire distributed between four sections. Table 1 describes each section in detail.
Statistical Package for the Social Sciences (SPSS), version 23.0, was used for data analysis. Descriptive data was presented in percentage (%) for categorical data and in mean and Standard Deviation (SD) for numerical data. Chi-Square test and Fisher’s Exact test were performed to compare the differences in level of knowledge about MTM service based on sociodemographic characteristics. In addition, Mann Whitney U test and Kruskal Wallis test were conducted to investigate the differences between sum score of KAP and sociodemographic characteristics.
A total of 130 questionnaires were distributed and 93 questionnaires were returned with response rate of 71.5%.
Table 3.1 displays the frequency of participants according to sociodemographic characteristics. Most of responders were female (N = 69, 74.2%). There were more responders in the age group 20–30 years old (N = 57, 61.3%) and majority of pharmacists were from Chinese ethnicity (N = 64, 68.8%). The highest number of pharmacists were holding bachelor’s degree (N = 82, 88.2%) and most of responders were outpatient pharmacists (N = 31, 33.3). Moreover, majority of pharmacists had 0–10 years of experience (N = 84, 90.3%) compared with pharmacists that had 11–20 years of experience (N = 9, 9.7%) (Table 2).
Knowledge of pharmacists about medication therapy management service
Ten different questions were used to assess pharmacists’ knowledge regarding MTM service (Table 3). The first five questions were about MTM service and the other questions were about MTAC. Each correct answer was given 1 mark with a total of 10 marks. The median of total score of knowledge was equal to 9. The minimum score obtained was equal to 6 and maximum score reported was equal to 10. Generally, majority of responders could answer most of the questions correctly which indicated that pharmacists had very good knowledge about MTM service.
Table 4 shows the level of knowledge of participants regarding MTM service. Majority of participants were considered with high level of knowledge (N = 86, 92.5%) compared to those with moderate level of knowledge (N = 7, 7.5%). While none of the pharmacists considered with low level of knowledge.
Apart from high level of knowledge (Table 5), higher knowledge regarding MTM service existed in female, younger pharmacists in age group 20–30 years old, Indian, pharmacists holding PhD degree and had 11–20 years of experience. All pharmacists working at MTAC, drug information center, total parenteral nutrition preparation and clinical pharmacists were with high level of knowledge and half of responders working at store were with high level of knowledge. There was a significant association between the level of knowledge and pharmacy practice setting (P = 0.004).
Attitude of pharmacists towards medication therapy management service
Table 6 shows that majority of the pharmacists agreed with most of the statements on attitude towards MTM service. High proportion of responders (92.5%) believed that pharmacist’s role is more than dispensing medications and 90.3% of them agreed that patients would receive more information about their chronic diseases and medicines by applying MTM service. 84.9% of pharmacists fully supported MTM service core elements and 79.6% of responders agreed that patient’s health outcomes would be improved when medications are monitored by a pharmacist as compared to other healthcare providers. Majority of pharmacists (91.4%) believed that MTM service requires more knowledge than basic information of pharmacy practice and high percentage of pharmacists (93.5%) agreed that applying MTM service would allow pharmacists to participate in patient care at a broader spectrum.
Practice of pharmacists regarding medication therapy management service
Table 7 describes the practice of pharmacists towards MTM service and the barriers that might affect MTM service implementation in the future. All pharmacists agreed that MTM service improves the quality of health services and most pharmacists were interested in providing MTM service in the future (92.5%). Moreover, 95.7% of them were interested in acquiring more information about MTM service. 87 pharmacists had a desire for taking training workshops regarding MTM service and 82 of them believed that online education system is a good way to provide training for pharmacists regarding MTM service.
About the barriers that might affect MTM service implementation, the most common barriers identified by pharmacists were lack of training (88.2%), need of high budget (51.6%), lack of time (46.2%) and difficulty to access current guidelines (24.7%). All pharmacists stated that the physical environment is not a barrier because the hospital contains counselling rooms.
Comparison of total score of KAP between the grouping variable
Examination of differences in total score of KAP between sociodemographic variables (Table 8) showed that there was a significant difference in total score of KAP between responders that were working at MTAC and outpatient pharmacy compared with pharmacists who were working at other pharmacy practice settings. Pharmacists who were working at MTAC and outpatient pharmacy had higher total score of KAP compared with the other group. Similarly, a significant difference in total score of KAP reported between pharmacists who had 0–10 years of experience compared to those that had 11–20 years of experience and showed that people with more experience had higher total score of KAP.
Nowadays, besides dispensing activity, pharmacist’s role has been expanded to include more services such as; patient counseling, enhance patients’ adherence and detect any adverse drug reaction associated with the therapy. Medication therapy management (MTM) service has been implemented to extend pharmacists’ services beyond the regular activities . MTM service is a direct patient care service and although pharmacists are the only healthcare professionals specifically identified as MTM providers in MMA but providing MTM service requires collaboration between all healthcare providers to achieve best therapeutic outcomes for individual patient . A recent review study, that included 21 references, has been conducted to detect the outcomes of pharmacist-nurse collaboration to enhance patients’ adherence to drugs. The results of this study showed that pharmacists and nurses could work together to achieve better outcomes .
MTM service becomes one of the potential and valuable clinical pharmacy services; therefore, the present KAP research studied the knowledge, attitude and practice of pharmacists regarding MTM service as well as established the potential barriers that might affect MTM service implementation.
Majority of pharmacists participated in our study were female (N = 69, 74.2%), Chinese (N = 64, 68.8%), holding bachelor’s degree (N = 82, 88.2%), young pharmacists in the age group 20–30 years old (N = 57, 61.3%) and had 0–10 years of experience (N = 84, 90.3%).
Compared with other international studies, our study showed that high percentage of Hospital Pulau Pinang pharmacists were with high level of knowledge regarding MTM service (N = 86, 92.5%). This result gave a good hint regarding the level of pharmacists’ awareness about MTM service. Similarly, In USA, cross-sectional studies showed that most of pharmacists had good knowledge regarding MTM service [14, 15].
Regarding the attitude of pharmacists towards MTM service, as showed in Table 6, most pharmacists were with positive attitudes about MTM service. This finding was in agreement with pervious study, done between all community pharmacists working at Iowa, USA, which showed that 90.1% of pharmacists agreed that MTM service is a valuable service and applying MTM service is an important step to enhance pharmacy practice career. Moreover, 86.2% of responders agreed that applying MTM service would give them good opportunity to give higher level of care to their patients . On average, Hospital Pulau Pinang pharmacists who participated in this study had positive attitudes regarding MTM service, similar to other international studies which concluded that pharmacists generally had positive attitudes regarding MTM service [15,16,17,18].
In terms of practice, most pharmacists reported that they have willingness to become MTM service providers in the future. This indicates that pharmacists have interest to improve their current services. All pharmacists participated in our study agreed that MTM service implementation will improve the quality of health services. In a systemic review study regarding “pharmacist-led medication review”, MTM service was defined as one of the services that used to optimize the therapeutic outcomes of patients and enhance the quality of services that were obtained by pharmacists .
Our study also identified the potential barriers that might affect MTM service implementation in the future. Four potential barriers to pharmacist provision of MTM service were assessed (1) training, (2) cost, (3) time, and (4) accessibility to current guidelines. This result was different than other studies done in USA, where pharmacists identified time as a major barrier [14, 16, 18, 20, 21]. 79.6% of Hospital Pulau Pinang pharmacists stated that they do not spend enough time with their patients and 53.8% of them think that they will have time to apply MTM service in the future. This finding indicates that around half of the pharmacists believed that MTM service will allow them to spend more time with their patients since majority of them do not give sufficient time to their patients because their role in the current practice is limited and include only the regular activities. Applying MTM service in the future will allow pharmacists to connect more with their patients because pharmacists will need to control all patients’ conditions and to collaborate with other healthcare workers to take the right decisions. Spending adequate time with patients will help pharmacists to be more involved in patients’ care plan and to give the optimal instructions to their patients and this will increase patients’ adherence to their medications and minimize hospitalization. Moreover, pharmacists were not reporting physical environment as a potential barrier because Hospital Pulau Pinang contains counseling rooms.
Regarding the differences in total score of KAP between sociodemographic variables, Table 8 showed that there was a significant difference in total score of KAP between responders that were working at MTAC and outpatient pharmacy compared with pharmacists who were working at other pharmacy practice settings as well as significant difference in total score of KAP reported between pharmacists who had 0–10 years of experience compared to those that had 11–20 years of experience. People who were working at MTAC and outpatient pharmacy were having higher total score of KAP comparing to pharmacists working at other places. This indicates that those pharmacists were more familiar with MTM service than others and that could be because they have direct contact with patients and they provide some of direct-patient services such as patients counseling service, giving patients additional pharmacological and nonpharmacological information regarding their diseases and therapies and enhance patients’ adherence to drugs. In addition, our study finds that pharmacists with more experience had higher score of KAP than others with less experience.
Strength and limitations
This is the first cross-sectional study conducted in Malaysia regarding medication therapy management. On the other hand, there were several limitations that appeared with the current study. Cronbach’s alpha value for knowledge part was equal to 0.326 and this value is low compared to Cronbach’s alpha values for attitude and practice parts. Furthermore, this study was conducted only at one hospital in Penang; so, the results of this study cannot extrapolate to predict the knowledge, attitude and practice regarding MTM service among all Malaysian pharmacists.
This study found that pharmacists had high level of knowledge and positive attitudes regarding MTM service, so further studies at other hospitals around Malaysia is recommended to take bigger picture about implementing MTM service in Malaysia. In addition, majority of pharmacists were interested to apply MTM service as well as they would like to know more information about MTM service, so we recommend doing many online and live workshops regarding MTM service and to enhance the knowledge of pharmacists regarding this service.
In conclusion, the research findings provide some insights about the Hospital Pulau Pinang pharmacists’ knowledge, attitude and practice regarding MTM service. Most of pharmacists were with high level of knowledge regarding MTM service and showed positive attitudes about MTM service. In addition, Majority of them had willingness to become MTM service provider in the future and were interested to know more information about MTM service. Moreover, participants recorded lack of training and requirement of high budget as the most common barriers that might affect implementation and provision of MTM service in the future.
