Palestine has a unique geographical location at the meeting point of the three continents (Asia, Africa and Europe). This location plays an important role in diversity of CAM products and encourages people here to use them. Community pharmacists, as an important part of the health care system, are in a position to give information to the customers with evidence-based information [
38]. Hence, to our best of knowledge, this study is the first survey in Palestine that investigate the community pharmacists practice, perception, beliefs about CAM and knowledge about different types and modalities of CAM in general and not only herbal medicines.
Demographic characteristics of the participant pharmacists
The socio-demographic characteristics of pharmacists in Palestine are similar to those in other parts of the world being mainly males (53.0%) [
29,
30,
38]. Contrary to other published data, in which females were the majority of the pharmacists [
6,
33]. Our data showed that the age of participant pharmacists ranged from 20 to 72 years (age was 35 ± 1.08 years; mean ± SD). The predominant age group being between 20 and 29 years (39.9%).Compared to the study conducted Jordan, the results regarding the range of age and years of experience of pharmacists were almost similar [
29]. However, Kheir and his coauthors in Qatar found that the average age was higher, therefore they had higher years of experience [
6].
Regarding pharmacy practice pertaining to CAM products, different types of CAMs were recommended by the Palestinian pharmacists. Exercises and food supplements were the two major recommended types. These results are almost in line with the findings of Awad (2012) in Kuwait where the most commonly used CAM modalities among students were herbal products, massage, nutritional supplements [
33]. Similarly, in Iranian survey, herbal therapy, cupping and massage therapy were considered of medium or high level efficiency by more than 60% of participants [
39]. This in part is consistent with the Kuwait study but somehow different from the USA study in which the most frequently used alternatives to conventional medicine were relaxation techniques, chiropractic, and massage [
33,
40,
41].
However, ritual Islamic spirituality including Quran, fasting, prayer, hejama and zamzam had a reasonable percent of pharmacist’s recommendations. The popularity of these types of CAM comes from its religious value and cultural believes. Alfaris et al. [
42] have found prayer and spiritual healing as one of the most often used complementary and alternative therapy in Saudi Arabia. Since the highest percent of responders were Muslims with the same believes as Saudi people, that’s why the recommendations of ritual Islamic spirituality were reasonable.
Pharmacists were also asked whether they prescribe supplements and herbs during the last year. Vitamin B
12 (93.2%), fish oil (86.8%), multivitamins (85.4%) were the highest prescribed agents. Deficiency of vitaminB
12is prevalent during all age groups was reported in different developing countries. Inadequate intake, due to low consumption of animal-source foods is the main cause of low serum vitamin B
12 [
43]. In Palestine, it was noted that during the last several years, serum vitamin B
12 determination was more frequently requested by the physicians and vitamin B
12 deficiency becomes as if it is an epidemic disease [
44].
Pharmacists’ practice and beliefs about CAM
Our results showed that the leading factor affecting pharmacist’s recommendation of specific CAM product was the proved efficacy of the product (87.2%) followed by the customer’s positive responses regarding product effectiveness (77.6%). Australian study conducted by Bushett and coauthors [
12] resulted in that brand familiarity was the main influence in pharmacist decision although the majority of pharmacists (88.2%) recommends generic name of the product only. Regarding the beliefs of pharmacists about CAM, the majority of the participants (96.5%) in this study agreed that CAM need more scientific testing before use. This finding is consistent with the results of a previous survey conducted by Sweileh et al. [
37], in which only 31% of respondents agreed that herbal drugs have been sufficiently studied. In the Australian study the result was also very close to our result, in which (91%) of the pharmacists agreed that CAMs need more scientific testing [
34]. Clearly, these results along with results of other studies show a global agreement among pharmacist on the need of CAM to be scientifically evident [
6,
33,
45].Interestingly, these results negates the general perception of CAM being ‘safe ‘[
45].
A fair number of pharmacists (42%) have a positive beliefs about CAM regarding the statement that results of CAM are mainly due to placebo effect. While, in the Australian study majority of the pharmacist have a neutral attitude about this statement (44%) [
34]. This can be attributed to cultural background and strong belief in benefits of CAM products among Palestinian pharmacists in the recent study, generally, people’s cultural and ethnic backgrounds can influence their propensity for using CAM [
46].
When comparing CAM with conventional medicine, non-surprisingly, only (27.1%) of the participants agreed with the statement that CAMs can offer therapeutic benefits that the conventional medicine does not, whereas (44.1%) disagreed. To some acceptable extent, this result agrees with a Singaporean study, which reported that only 15% of pharmacist recommended CAM because they are unsatisfied with results of conventional medicine, while 26% were satisfied with conventional medicine. This can reflect a general trend among pharmacists to CAMs as any complement medicine rather than alternative to conventional medicine, and dissatisfaction with conventional medicine is not necessarily the reason for turning to CAM.
Interestingly, the majority of the pharmacists (64.4%) agreed that CAM improve general health and not only cure the disease, in agreement with the Singaporean study, the main reason for using CAM was reported as improving general health and promote wellbeing [
33]. This supports the idea of CAM as a preventive as well as curative measure to treat health problems. A great majority of the pharmacists (76.5%) showed agreement with statement that pharmacists should regularly ask consumer if they use CAM, positively, this reflects the awareness of pharmacist upon safety measurements and drug-herbal interactions that can affect consumer’s safety. In the Australian study, surprisingly, the percent was 100, which reflects a high level of awareness. Eventually, research regarding both conventional and CAM therapies is ongoing and the medical evidence can change rapidly, the clinician should communicate regularly with the patient regarding any new developments [
47].
When comparing the beneficial effect of CAMs with conventional medicine, we asked the respondents weather they agree that alternative medicine offers the patient benefits not offered by conventional medicine. Only 27.1% agreed with this statement while in an Australian study about Complementary Medicines among hospital pharmacists, conducted by Brown (2009), the results were close to ours in which only 35% agreed with this statement. Our result is much lesser than the result of Sweileh et al. [
48] study which reported that 61% of pharmacists believed that herbal medicine was more beneficial and safer than conventional medicine. This could be attributed to either the time/regional difference between the two studies or the fact that Sweileh’s study was focused only in herbs and therefore the numbers were higher when compared to our results which focused on CAM in general.
In this study more than half of the pharmacists 57.3% (161 pharmacists) showed confidant discussing CAM with the consumers. Comparing this with their knowledge score (a score of 4.32 ± 1.78, mean ± SD), the level of confidence is conformed to their fair knowledge. However, in the previous survey by Sweileh, majority of pharmacists rated their knowledge as good while the actual testing scores, which was reported to be poor, did not substantiate this impression [
37]. On the other hand, the Australian study investigating hospital pharmacist attitude, reported lack of both confidence and knowledge. Generally, pharmacists showed fair beliefs about CAM, based on beliefs about CAM score test with a mean of 4.2 of 7.
Besides, several approaches were made to correlate pharmacist attitude with demographic characteristics, as shown in Table
3, there was no significant difference in beliefs score within the socio-demographic groups. Regarding the barriers that limit appropriate CAM recommendation by the pharmacists, the most reported two in this study are the small number of well-trained pharmacists on CAM use (82.6%) followed by lack of scientific knowledge in CAM (73.7%).
Pharmacists’ knowledge about CAM
The finding of this research draw an attention on patient safety and pharmacists educational and training needs. The pharmacists’ scores from the knowledge test were fair, with a median of 5.00 ± 1.78 (mean score 4.32 ± 1.78) out of 8 questions. Pharmacists were more likely to answer statements about the side effect and contraindication of the herbal products as shown in Fig.
1, this sounds good regarding patient safety, which is one of the biggest concerns related to CAM use. However, since the percentage of responders to these questions was low (24.2%), we should not neglect the importance of increasing pharmacists awareness of the potential harmful effects that CAM may cause by Continuing Education and Training.
The observed knowledge score is higher than a previous survey about pharmacists knowledge of natural herbal product in Qatar where pharmacists mean score was 4.51 ± 3.57 (mean ± SD), when they answered 12 questions about knowledge of natural herbal product [
6]. Inappropriately, our study illustrated that Palestinian pharmacists’ knowledge scores are lower than the survey done in Singapore about pharmacists knowledge toward CAM with a mean score of 7.23 ± 1.96 (mean ± SD), when pharmacists answered the knowledge test consisting of ten questions [
45].
No differences were found in knowledge score between males and females, whereas in Qatar survey female pharmacists showed superior knowledge scores than males [
6]. However, there is a difference found in knowledge score between the different groups of age and years of experience. With the lower age, lower years of experience having the highest knowledge score. A possible explanation for this might be that the newly graduated pharmacists had taken relevant courses about CAM during their undergraduate studies. These results related to the years of experience conform to the result of survey published in 2013 about Dispensing Practices, Attitudes, and Knowledge of Pharmacists towards Herbal Products in Palestine [
37].
As expected, there is statistically significant difference in knowledge score based on educational level. Pharmacists with postgraduate studies (master and PhD degree) have a higher knowledge score, this is logical due to the increased years of education with more courses being studied that may be related somehow to CAM.
One interesting finding is the significant difference between knowledge score and the University of Graduation, with the pharmacists locally graduated from Palestinian universities having the highest knowledge score. This may reflect the improved educational levels offered by local universities and the attention given to the common CAM in our countries, by offering courses about their indications, side effect, contraindications and the interactions. The pharmacists knowledge scores are higher in those where their pharmacies located in village, this may be due to the wide believe in CAM in the village, where the community pharmacists are the first health care provider from whom patients seek recommendations on CAM products.
The increasing number of patients using CAM pose a challenge to pharmacists. Therefore, pharmacists need to incorporate CAM learning into their continuing professional development plan to improve their knowledge and skills in dealing with patients taking CAM. Educational meetings alone or combined with other interventions, can improve professional practice and healthcare outcomes for the patients [
49].
Echinacea is one of the available herbal products found in our pharmacies. Echinacea preparations, commonly perceived as herbal immune stimulants or “cold fighters,” are among the most widely used dietary supplements in Europe and the United States [
50]. As the results show only (33.8%) were familiar with its indication, while (91%) of community pharmacists in Riyadh, Saudi Arabia were more familiar with this indication [
31].
Finally, pharmacists were least familiar with the drug – herb interactions (12.5%). Only about (19.6%) were aware of the interaction of digoxin with bran. Whereas, more than half of the pharmacists were aware of Garlic (
Allium sativum) and warfarin interaction in term of bleeding. As shown in the practice part Garlic (
Allium sativum) is prescribed by (42.7%) of the pharmacists. In 2007, a published research about the effects of garlic on platelet biochemistry and physiology concluded that garlic inhibits platelet aggregation by multiple mechanisms and may have a role in preventing cardiovascular disease [
51]. Another study showed that CAM use in Asian patients is prevalent and associated with the ‘chronic disease triad’ (of arthritis, musculoskeletal disorders and stroke), satisfaction with care and cultural beliefs [
52]. This put an effort on the pharmacists to be more aware of this interaction.
The most frequently needed information are related to the safety of CAMs, which included drug interactions (71.2%), use in pregnancy (70.8%) and side effects (64.8%). These results are in agreement with those obtained by Bushett and coauthors [
12] in Australia, in which the percentage of pharmacists needed the above information were 95% for drug interactions, 76% for contraindications and 75% for side effects. It was expected that the most information needed among participant is about CAM types and drug interactions as Sawalha’s [
22] study in Palestine showed that there was a significant correlation (p -value of 0.039) between the number of health conditions treated and the number of CAM types used. Also in the same study, herbal therapy was the most commonly used. Pokladnikova et al. [
53] showed that pharmacists obtained information on CAM mainly from pharmacy journals (69%) and the internet (60%) [
53]. In our study, the main source of information was internet (66.9%) and specific websites (47%). It is not surprisingly that internet research has the highest percentage, because there is a wild spread of the modern mobile phones with many applications that help to reach to the information faster and easier.
