Phase 1: Simulated Patient Phase
Sociodemographic data
A total of 75 different community and chain pharmacies were visited by the simulated patient. Around half of the pharmacists were females (50.6%) and working in the mid-day shift B (53.4%). In parallel, more than two thirds of the visited pharmacies were individual pharmacies (76.0%). There were no significant differences between the two conducted scenarios in terms of the gender of the pharmacist included in the study, pharmacy location, pharmacy shift, or pharmacy status. Table 1 summarizes the characteristics and demographic data of the visited pharmacies.
Pharmacists Agreement with Deanxit® administration
As provided in Figure 2, the majority of the pharmacists agreed with the use of Deanxit® in the first and second scenarios, 48% and 97%, respectively. Some of the pharmacists who disagreed with Deanxit's suggestion in the first scenario (IBS scenario), suggested an alternative. While, no alternatives were provided for the second (mood disturbances) scenario, as provided in (Figure 1S), some of which are medications and others are herbal supplements. Poxidium® (Chlordiazepoxide and Clidinium bromide) was the most alternative prescribed (n=8, 36.3%).
Pharmacist's practice regarding Deanxit® dispensing.
According to pharmacists’ patient care process formulated by the joint commission of pharmacy practitioners, Table 2 shows that pharmacists’ mean practice score. As demonstrated, the pharmacy practice was poor, hence the score was 0.5867 out of 18 (SD = 0.68). Only 22 pharmacists out of 75 provided pharmaceutical education and instructions on how to use the drug (33.3%). While they provided a variable answers for Deanxit dosing Table 3.
Phase 2: Structured interviews phase
Sociodemographic characteristics of study participants
A total of 240 different community pharmacists were visited in this study. Eight pharmacists disagreed to take part in the study and five pharmacists did not recognize the medication (Deanxit®). Accordingly, 227 responses were included in the final analysis. Pharmacies were distributed in four different provinces, (n=55, 24.2%) pharmacies in Eastern Amman, (n=59, 26.0%) in Western Amman, (n-58, 25.6%) in urban districts in Irbid and (n=55, 24.2%) in trade mart areas in Irbid. Of the responders, (n=144, 63.4%) were females and most of the respondents had a bachelor's degree (n=193, 85.0%). The sociodemographic characteristics of the respondents are presented in Table 4.
Pharmacists’ experience with Deanxit®dispensing
The majority of interviewed pharmacists (n=217,96%) reported that Deanxit used to be dispensed without a prescription. While, more than half of the interview pharmacists (n=141,62.1%) reported the exposure to at least one case of improper use of Deanxit, Figure 3.
Among the pharmacists who had ever exposed to Deanxit® improper use (n=141), there were varied answers about these uses including: "Deanxit could be used for mood disorders and to calm down" (n=37, 26.2%), " Deanxit could be used for euphoria in an addictive way" (n=36, 25.5%) and " Deanxit could be used for sleep disorders and insomnia" (30, 21.2%). Other improper uses reported by interviewed pharmacists are listed in Table 1S. In addition, Figure 2S illustrates that the source of information mostly guides Deanxit® improper users to use it according to pharmacists' answers in the structured interviews are friends (n=127) and family (n=122). In addition, most of the pharmacists (n=114, 80.8%) reported that the improper Deanxit® users often ask directly for it. Further data regarding improper users reported by the pharmacists are presented in Table 2S.
Pharmacists practice toward patients who are suspected to use Deanxit® improperly
Eighty-four pharmacists (n=84, 59.5%) declared that they would still dispense Deanxit®, even, in case of improper use confirmation. While, 43% of them stated the refusal to dispense or claim that the product is not available, more details in Table 3S.
Pharmacists’ knowledge regarding Deanxit®
In general, pharmacists showed poor knowledge about Deanxit®. The overall median knowledge score was 2.0 out of 15 (IQR = 3.0). Aspects are all listed in Table 5. Upon asking if there are any unlabeled indications of Deanxit®, about three-quarters of pharmacists answered yes (n=167, 73.5%), Table 4S lists these unlabeled indications that are mentioned by pharmacists in the interviews. Out of the 167 pharmacists who stated the presence of Deanxit® unlabeled indications, the most frequently mentioned indication was irritable bowel syndrome (n=102, 61.0%), followed by sleep disorders (n=60, 35.9%). Table 6 shows factors associated with pharmacists' knowledge score about Deanxit®, age, marital status, years of experience and highest education level were significantly affecting the knowledge score (P-value <0.05) at single linear regression. However, only the highest education level significantly affected the pharmacist knowledge score when multiple linear regression was conducted, in which the higher the education levels the highest the knowledge score.
