Abstract
Background and objectives
Practice-based research (PBR) is of pivotal importance for hospital pharmacists which not only up-grades the profession but also improves the patient care. This study aimed to evaluate the attitude, perception, willingness, motivation and barriers to PBR among hospital pharmacists in Pakistan.
Methods
A descriptive, cross sectional study design was employed. Data were collected between 1st December, 2017 and 1st March, 2018 from 130 hospital pharmacists employed in 41 hospitals of Lahore, Pakistan. A survey instrument comprising of six sections was designed to determine the attitude, perception, willingness, motivation and barriers to PBR. Data were analyzed by using Statistical Package for Social Sciences (IBM SPSS Statistics for Windows, version 21.0, Armonk, NY: IBM Corp.). The normality of the data was determined through Shapiro-Wilks and Kolmogorov-Smirnov tests. Independent Samples Mann-Whitney U Test and Independent Samples Kruskal-Wallis Test were carried out to test if there were differences among the characteristics of the hospital pharmacists. Logistic regression analysis was used to figure out the factors associated with attitude, perceptions, willingness and motivation towards PBR. A p-value <0.05 was used for statistical significance of differences.
Results
A total of 141 pharmacists were approached. Among them, 130 responded to the survey (response rate 92%). Out of a maximum score i.e., 5 (100%) the respondents obtained a median score of 4 (IQR = 0) for attitude, perception and motivation towards PBR; whereas, a median score of 4 (IQR = 1) was obtained for willingness thus demonstrating fair positive attitude, good perceptions, increased motivation and willingness towards PBR. The most common barrier limiting the pharmacists’ participation in PBR was lack of time (23.8%) followed by lack of incentives (16.2%) and lack of support (14.6%). Results of the logistic regression analysis revealed that hospital pharmacists practicing in the inpatient settings had 4.56 times more positive attitude towards PBR (OR = 4.56, 95%CI = 1.07─19.42, p-value = 0.040) as compared to those practicing in the outpatient settings. The male hospital pharmacists (OR = 8.86, 95%CI = 1.15–53.74, p-value = 0.017), those practicing in the outpatient (OR = 23.51, 95%CI = 2.04─271.53, p-value = 0.011) and inpatient settings had increased motivation towards PBR (OR = 12.24, 95%CI = 1.61─94.66, p-value = 0.016).

Introduction
Medical research demands continuous up-gradation of professional practice and knowledge [1]. Thus, it is very crucial to develop the interest of pharmacists towards practice-based research (PBR). Pharmacy practice research is defined as, “a component of health services research that focuses on the assessment and evaluation of pharmacy practice” [2]. PBR not only improves the quality of pharmaceutical care but also helps to extend its scope [3]. In the past, pharmacists were reluctant to conduct research [4] but this trend has been changed with the passage of time. PBR is now being increasingly acknowledged and supported by pharmacy organizations globally [5]. The American College of Clinical Pharmacy (ACCP) is working to pave ways for the betterment of human health and quality of life by encouraging pharmacists to be a part of the research [6]. Similarly, the Canadian Society of Hospital Pharmacists has also developed a research and education foundation for enhancing the research skills of pharmacists [3]. It is essential to conduct more research for spreading awareness about the concept of PBR and its impact on the betterment of the community. Most of the pharmacists practicing in developing countries lack interest in research activities. In contrast to this a Qatari study showed that more participants were ardent to participate in PBR, though some obstacles were also there [7].
The social cognitive theory states that researchers are greatly influenced by the environmental and personal factors [8]. Environmental factors are related to the financial rewards, support and encouragement from concerned authorities. The personal factors are the one’s own interests and curiosity, desire to flourish and to improve the skills and knowledge related to disease management. Both of these factors play a pivotal role in the researchers work. According to this theory the thoughts, beliefs and feelings of a person has a strong influence on his behavior. If a person has positive attitude towards research, understands the importance of research in uplifting the profession and is cognizant of the motivators and barriers in research then he could play a pivotal role in conducting PBR. Literature suggests that the involvement of pharmacists in PBR can lead to better patient outcomes; however, the pharmacists have to overcome certain barriers in this regard. These barriers include inadequate training, lack of skills and competency required for PBR [9–11]. Although, number of hospital pharmacists is continuously increasing with each passing year but there is scarcity of data that reflects the ongoing scenario of PBR in Pakistan or other developing countries. Most of the literature pertaining to PBR has been reported from developed countries [12, 13]. In such circumstances, it is necessary to scrutinize the opinions and inclination of hospital pharmacists in Pakistan about their participation in PBR. This aspect has not yet been explored in Pakistan and warrants attention. Therefore, the focus of this study is to evaluate the attitude, perception, willingness, motivation and barriers to PBR among hospital pharmacists in Pakistan.
Methods
Study design and settings
A descriptive, cross sectional study design was employed. Out of the total 66 hospitals present in Lahore, hospital pharmacists are employed in 41 hospitals (23 private, 17 public, and 1 military hospital). Lahore is the 32nd most populated city in the world and second most populated city in Pakistan, with the population of 15,245,000 [14]. This city has a total of 48 private, 17 public, and 1 military hospital for catering the needs of the growing population [15]. The study was conducted among those 41 hospitals of Lahore, Pakistan where hospital pharmacists were employed.
Study population and sample size
Study population consisted of hospital pharmacists employed in private and government hospitals of Lahore. The total sampling strategy was used for the current study. All the hospital pharmacists (n = 141) working in Lahore were approached out of which 130 hospital pharmacists consented to participate in this study.
Data collection
Data were collected between 1st December, 2017 and 1st March, 2018. An additional note was attached with each questionnaire which defined the aim of the research. An extensive literature review of previously published findings was executed [13, 16, 17] and a survey instrument was designed [S1 Appendix]. Three experienced pharmacy practitioners and professors assessed the survey instrument for face and content validity. Centered on their opinions, the questionnaire was adjusted and piloted on 10 hospital pharmacists’ prior to its administration among the study participants.
The survey instrument had six distinct sections. The first two sections sought the attitude, perception and willingness of hospital pharmacists towards PBR and were measured on a five point Likert scale (5 = strongly agree, 4 = agree, 3 = neutral, 2 = disagree and 1 = strongly disagree). The third section included the factors that motivated the pharmacist to be a part of research and was also measured by the Likert scale. The fourth section examined the barriers in executing research such as lack of time, support and knowledge etc. The fifth section explored the main areas of interest for research and the final section comprised of the participant’s demographics.
Data analysis
Data were analyzed by using Statistical Package for Social Sciences (IBM SPSS Statistics for Windows, version 21.0, Armonk, NY: IBM Corp.). Internal consistency of the questionnaire was measured by Cronbach’s alpha, while reproducibility was evaluated using intra-class correlation for each item in the attitude, perceptions, willingness, and motivation scales, with acceptable values ≥0.6. Calculation for Cronbach’s alpha was made as 0.77 for attitude, 0.73 for perceptions, 0.75 for willingness, and 0.73 for motivation section. Descriptive statistics such as frequencies, percentages, median and interquartile ranges were used to analyze the data. Moreover, the normality of the data was determined through Shapiro-Wilks and Kolmogorov-Smirnov tests. Outcomes regarding attitude, perceptions, willingness and motivation towards PBR were dichotomized as “Positive” versus “Negative”, “Good” versus “Poor”, “More” versus “Less”, and “High” versus “Low”, respectively. Median scores of ≥3 were considered as “Positive”, “Good”, “More”, and “High”; whereas, scores <3 were considered as “Negative”, “Poor”, “Less”, and “Low”, respectively. Independent Samples Mann-Whitney U Test and Independent Samples Kruskal-Wallis Test were carried out to test if there were differences among characteristics of the hospital pharmacists with regard to their attitudes, perceptions, willingness and motivation towards PBR. Logistic regression analysis was performed to figure out the factors associated with attitude, perceptions, willingness and motivation towards PBR. Results were expressed as Odds Ratio (OR) accompanied by 95% Confidence Intervals (95%CI) and a p-value <0.05 was used for statistical significance of differences.
Ethics approval and consent to participate
The ethical approval was obtained from the Pharmacy Research Ethics Committee (PREC) at the Akhtar Saeed College of Pharmaceutical Sciences (Reference: 16-2017/PREC, dated November 23, 2017). Before initiating the study, the purpose and protocols were thoroughly explained to participants and written consents were also obtained.
Results
Characteristics of the participants
A total of 141 hospital pharmacists were approached. Out of them, 130 participants agreed to participate in the survey (response rate = 92%). Most of the respondents were male (n = 75, 57.7%) and had a professional experience of less than 2 years (n = 67, 51.5%). Most of the respondents had neither any clinical training (n = 74, 56.9%) nor other board certifications (n = 108, 83.1%). Majority of them were interested in surgical unit (n = 23, 17.7%), employed in inpatient departments (n = 66, 50.8%), and had major research interest in the field of therapeutics (n = 24, 18.5%) (Table 1).
Attitude towards research
Out of a maximum score i.e., 5 (100%) for the attitude towards PBR, the respondents obtained a median score of 4 (IQR = 0), demonstrating a fair positive attitude towards PBR.
Majority of the respondents (n = 117, 90%) agreed (Strongly agreed (SA) + Agreed (A)) with the statement “Pharmacy practice research is significant in recognizing and examining complications in pharmacy” (Median = 4, IQR = 1). Similarly, most of the respondents (n = 112, 86.2%) agreed (Strongly agreed (SA) + Agreed (A)) with Item no. 2 (Median = 4, IQR = 1). For details please refer to Table 2.
Perceived importance of research in pharmacy practice
Out of a maximum score i.e., 5 (100%) for the perceptions towards PBR, the respondents obtained a median score of 4 (IQR = 0), demonstrating good perceptions towards PBR.
Majority of the respondents (n = 113, 86.9%) agreed (Strongly agreed (SA) + Agreed (A)) with the statement “It is crucial to be well-informed of the research fitting to the practice of pharmacy” (Median = 4, IQR = 1). Similarly, most of the respondents (n = 111, 85.4%) agreed (Strongly agreed (SA) + Agreed (A)) with Item no. 5 (Median = 4, IQR = 1). For details please refer to Table 3.
Willingness to participate in research
Out of a maximum score i.e., 5 (100%) for the willingness towards PBR, the respondents obtained a median score of 4 (IQR = 1), demonstrating high willingness towards PBR.
Majority of the respondents (n = 112, 86.2%) agreed (Strongly agreed (SA) + Agreed (A)) with the statement “I have the required abilities to participate in research” (Median = 4, IQR = 0). Similarly, most of the respondents (n = 112, 86.2%) agreed (Strongly agreed (SA) + Agreed (A)) with Item no. 4 (Median = 4, IQR = 1). For details please refer to Table 4.
Motivators and barriers to take part in research
Out of a maximum score i.e., 5 (100%) the respondents obtained a median score of 4 (IQR = 0) for the motivation towards PBR thus demonstrating increased motivation towards PBR.
Majority of the respondents (n = 122, 93.9%) agreed (Strongly agreed (SA) + Agreed (A)) with the statement “Provide better services and increased patient care” (Median = 4, IQR = 1). Similarly, most of the respondents (n = 121, 93.1%) agreed (Strongly agreed (SA) + Agreed (A)) with Item no. 1 (Median = 4, IQR = 1). For details please refer to Table 5.
A number of barriers limiting pharmacists’ participation in PBR were identified. The most common barrier reported by most of the pharmacists was lack of time (n = 31, 23.8%) followed by lack of incentives (n = 21, 16.2%), lack of support (n = 19, 14.6%) and lack of knowledge (n = 15, 11.5%). Please refer to Table 6.
Difference in hospital pharmacists’ attitude, perceptions, willingness, and motivation towards PBR
Independent samples Mann-Whitney U Test showed a significant association (p-value <0.05) between gender and attitude, perceptions, and willingness of hospital pharmacists towards PBR. Independent samples Kruskal-Wallis Test showed that area of practice was found to be statistically associated (p-value = 0.031) with the motivation of hospital pharmacists (Table 7).
Results of the logistic regression analysis revealed that hospital pharmacists practicing in the inpatient settings had 4.56 times more positive attitude towards PBR (OR = 4.56, 95%CI = 1.07─19.42, p-value = 0.040) as compared to those practicing in the outpatient settings. Furthermore, male hospital pharmacists had 8.86 times increased motivation towards PBR (OR = 8.86, 95%CI = 1.15–53.74, p-value = 0.017) as compared to female hospital pharmacists. Similarly, hospital pharmacists practicing in the outpatient settings had 23.51 times increased motivation towards PBR (OR = 23.51, 95%CI = 2.04─271.53, p-value = 0.011) and hospital pharmacists practicing in the inpatient settings had 12.24 times increased motivation towards PBR (OR = 12.24, 95%CI = 1.61─94.66, p-value = 0.016) as compared to those practicing in other settings (Table 8).
Discussion
The current study set out to determine the attitude, perception, willingness, barriers and motivation towards PBR among hospital pharmacists in Pakistan. Some studies conducted in developing countries revealed that the pharmacists were least interested in conducting research [4, 18, 19]. In contrast to this, the results of the present study showed that Pakistani hospital pharmacists were not only well aware of the importance of PBR in emerging pharmacy practice but were also willing to participate in PBR. The outcome of the survey indicated that pharmacists understood the significance and worth of research for their practice, profession, and patient care. A large number of hospital pharmacists were willing to participate in research. However, several barriers related to lack of time, support, incentives and never being asked to participate in research were also reported.
Findings of the current study revealed that hospital pharmacists had a fair positive attitude towards PBR. Participants strongly agreed/agreed that “Pharmacy practice research is significant in recognizing and examining complications in pharmacy” and “Pharmacy practice research is vital in pharmacy decision-making”. This is in line with the findings of a study conducted by Sultana et al. [3]. PBR has beneficial impact on pharmacists in terms of obtaining knowledge, improving expertise through evidence-based practice and rationalizing the decision making process in the provision of patient-oriented services. A significant role can be played by the hospital pharmacists in research due to their direct involvement in provision of optimal care to the patients. Moreover, they are in an ideal position for implementing evidence based pharmaceutical care to the patients. In the current study, 89% of the participants strongly agreed/agreed with their interest in conducting research which is comparable to the findings of a Qatari study in which 70% of pharmacists showed interest in being a part of PBR [4]. Nearly half of the respondents agreed that they understood research terminologies. This is in contrast to the previous studies that demonstrated a relatively poor knowledge of standard health related research terms among physicians and pharmacists [13, 20]. If the pharmacists are unaware about the research terminologies then they would be unable to assess any paper provided by the pharmaceutical firms or other healthcare professionals. The enhancement of critical thinking skills and familiarity with the research terminologies is of great importance for hospital pharmacists. Our study showed that the hospital pharmacists practicing in the inpatient settings had more positive attitude towards PBR as compared to those practicing in the outpatient settings. It might be due to the fact that the pharmacists working in inpatient settings had more interaction with the patients as compared to those working in outpatient settings who were merely involved in administrative tasks like dispensing of medicines. However, future studies are needed to explore the relationship between pharmacists’ attitude and hospital setting.
Respondents in the current study demonstrated good perceptions towards PBR. Many participants disagreed with the statement “Being a practicing pharmacist the research findings are inapt to me” justifying the importance of PBR. Majority of the pharmacists agreed with the statement “Research is of pivotal importance for a pharmacist”. Similar positive perceptions have been reported in an Australian study [21]. The findings of the current study revealed an increased willingness of respondents towards PBR. Participants strongly agreed/agreed that “I have the required abilities to participate in research” and “I would need observation to participate in research”. This is in contrast with the findings of a study conducted in the United Kingdom (UK) where only 32 to 50% of the pharmacists were interested in conducting research [22]. A possible explanation for such differences could be attributed to the difference in the study settings since the pharmacists working in above mentioned study were working in the community settings as opposed to current study where pharmacists were employed in hospital settings. Findings of the current study also depicted that more than half of the respondents were confident about their skills and ability to carry out a research project. This is comparable with the findings of other studies [4, 7, 17, 21]. In contrast to other studies nearly one quarter of the participants were of the opinion that monetary benefits did not have an influence on their research interests [17, 21].
Study participants also showed an increased motivation towards PBR. Participants strongly agreed/agreed with the statement “Provide better services and increased patient care” and “The pharmacy profession would be uplifted”. The factors that motivated the pharmacists to take part in PBR included the desire of uplifting the pharmacy profession, provision of better services and increased role in patient care, continuous medical education and for sustaining research activities. Similar motivational factors have been reported in other studies [13, 23]. Furthermore, male hospital pharmacists had increased motivation towards PBR as compared to female hospital pharmacists. However, the exact reason behind the relation of gender with motivation needs to be explored.
Our study revealed that the major barriers that hindered the participation of pharmacists in research were the lack of time, lack of incentives, lack of support, and lack of knowledge to conduct PBR. Lack of time has been reported to be a major barrier in various previously published studies [13, 21, 24]. In concordance with the findings of our study, other studies have also reported lack of support as one of the barriers [7, 21]. Moreover, lack of awareness and never being approached has been termed as barriers elsewhere [13]. Lacks of confidence, inadequate skills, knowledge, and training have been termed as barriers in multiple studies [7, 21, 22]. It was quite encouraging that the respondents had trust on their capabilities, knowledge and ability to carry out research. The responsibility lies on the national and international organizations to overcome the barriers faced by pharmacists having positive attitude, perception and willingness to participate in PBR.
This study has few limitations as well. First, the study was conducted in a single city of Pakistan, so results could not be generalizable to the entire country. However, the healthcare system and curriculum of healthcare professionals is similar across the country and the findings are likely to be similar for entire country. Second, some estimations of CI in Table 8 were very wide; the point estimate was not in the midpoint of the CI, which indicated a lack of precision. Data was rechecked to ensure that the CI was actually asymmetrical rather than being a calculation error. It was possibly due to the limited sample size or high variability in responses of participants. Last, the possibility of non-response bias and self-report bias could not be ruled out due to the utilization of self-administered questionnaire. There might be some differences in the accuracy or completeness of the recollections retrieved by the participants, and an under or over-reporting of attitude, perceptions, willingness, and motivation scales.
Conclusion
The respondents had fair positive attitude, good perceptions, increased motivation and willingness towards PBR which is a promising finding. The most common barrier limiting pharmacists’ participation in PBR was lack of time followed by lack of incentives and lack of support. Male gender was found to be statistically associated with positive attitude, perceptions, and willingness towards PBR. Similarly, area of practice was found to be statistically associated with the motivation of hospital pharmacists.
