TL;DR

This study examines how psychotropic medications are prescribed in Jordan's primary healthcare, finding significant issues with inappropriate prescriptions.

Contribution

The study provides new insights into psychotropic medication prescribing patterns and pharmacist interventions in Jordan's primary care.

Findings

19.4% of psychotropic medication prescriptions were found to be inappropriate.

Pharmacists dispensed 78.7% of the prescribed psychotropic medications.

Inappropriate prescriptions included overprescribing, underprescribing, and incorrect medication choices.

Abstract

Background: Although psychotropic medications (PMs) have enormous adverse events and may cause serious harm if administered inappropriately, there is a scarcity of research concerning the patterns and appropriateness of prescribing these medications in primary care in Jordan. This study aimed to investigate the patterns and appropriateness of PM prescription in primary care, as well as the types and frequency of pharmacist interventions in community pharmacies. Methods: A prospective observational study was conducted in 16 community pharmacies across Jordan. A data reporting sheet was developed, validated, piloted to ensure its applicability, and filled out over 12 weeks (April to June 2023), covering three regions in Jordan. Results: Overall, 426 patients with 469 prescriptions containing 919 PM orders were observed. Among the PMs prescribed, 19.4% were prescribed inappropriately. Among the PMs, 78.7% were dispensed by pharmacists. The inappropriate prescription categories (n = 178) were overprescribing (45, 25.3%), underprescribing (19, 10.7%), inappropriate medication choice (39, 21.9%), inappropriate duration of medication therapy (64, 36.0%), and inappropriate medication dosage (11, 6.2%). The top therapeutic category requested was anti-epileptics (23.9%). Conclusions: This study evaluated the prescribing patterns and appropriateness of PMs in Jordan, revealing notable instances of inappropriate PM prescriptions alongside varied and extensive pharmacist interventions.

1. Introduction

Psychotropic medications (PMs) are an increasingly prevalent solution to mental health disorders [1]. Major depressive disorder, anxiety disorders, bipolar disorder, and schizophrenia are just some conditions commonly treated using psychotropics as they have direct neurotransmitter-regulating properties that regulate mood disorders or manage associated symptoms [2].

The prescription of psychotropic medications is performed by healthcare professionals such as psychiatrists, primary care physicians, clinical pharmacists, and nurse practitioners [3]. These practitioners take account of everything including patients’ symptoms, medical history, and other situations that are relevant when they ask for PMs. Once a medication is prescribed, a community pharmacist serves as an intermediary between the prescriber and the patient, being responsible for the management of medication therapy and the safe storage conditions of medication [3].

PMs have been widely known for the effective management of these mental illness disorders; yet, some debates have arisen about their appropriate applications. The misuse, overuse, and underuse of PMs may be considered as adverse events that should always be avoided [4]. Overuse occurs when patients consume too many medications at high dosages or for extended duration [4]. Side effects, medication errors, and dependence or addicting possibilities may be the consequences of this [4]. Underuse can be described as when patients do not take medicine correctly or are provided with medicine that is inadequate or outdated. It is often the case that with improper usage, people experience adverse events and their symptoms are aggravated. However, abuse denotes those instances when someone excessively uses a drug in a way that is detrimental to themselves; this encompasses both physical dependence and psychologic dependence [4,5].

The role of the community pharmacist in mental health services is evolving quickly, with increasing levels of mental illness and the need for convenient, patient-centred care. Traditionally focused on dispensing medication, pharmacists are now being recognized more and more for their ability to influence several aspects of mental health service delivery. Experiments have shown the efficacy of training courses in enhancing pharmacists’ attitudes, knowledge, and skills in mental health, in addition to their competence in care delivery, and reducing stigma [6]. Experiments have also examined pharmacist-provided interventions such as collaborative drug therapy management and the improvement of psychotropic medication use and adherence [7]. Further, studies on prescribing antidepressants emphasize the importance of treatment duration and medication selection [8]. There are still ongoing issues, including communication with other professionals, resources, and the general problem of stigma [9,10,11]. This overview shows the mounting evidence base for incorporating community pharmacists into mental healthcare teams and stresses the need to bridge existing obstacles and optimize collaborative models.

Moreover, studies have proven that Jordanian community pharmacies offer services, such as blood pressure measurement, weight measurement, ear piercing, and first aid. Individuals rely on pharmacists for medication counselling and the management of minor ailments; hence, pharmacists are well suited to offer such advice as well as educate on different types of drugs or supplements [12].

The awareness of how PMs are dispensed by community pharmacists is crucial to identify areas in which to improve the prescribing process. By considering factors, such as patient demographics, medication type, prescriber characteristics, and pharmacy characteristics, we can recognize potential issues while devising plans to promote the appropriate use of such drugs and improve care quality while protecting the safety of mental health disorder patients. This study aimed to investigate the pattern of PM prescription in primary care in Jordan, with a focus on the appropriateness of prescription as well as the characteristics of pharmacists’ interventions in community pharmacies.

2. Materials and Methods

2.1. Study Design

A prospective observational study was conducted to collect data in a real-world setting, providing insights into the prescription practices in primary care and pharmacist interventions in community pharmacies across Jordan.

Ethical approval was granted by the Research Ethics Committee of The University of Petra to ensure adherence to standards, while safeguarding participants’ rights and well-being (O/3/8/2023).

2.2. Study Flow and Settings

A data reporting sheet was developed by the principal investigator after reviewing the relevant literature. The sheet was validated by three experts (psychiatrist, clinical pharmacotherapist, and pharmacist) using a scoring technique. The sheet was piloted by two pharmacists over a period of three days to check its applicability. Based on the feedback received, minor changes were made to the sheet. The reliability of the data reporting sheet was checked with the Kappa coefficient technique. This yielded a score of 0.89, indicating substantial agreement between observers. Finally, full-scale data collection was carried out by distributing the reporting sheet to pharmacists, who filled it out over a period of 12 weeks (April to June 2023).

2.3. Sample Size

The sample size was calculated using the formula n = (Z^2^ × P × (1 − P)) /d^2^, where Z = Z-score corresponded to the desired confidence level, P = estimated prevalence (proportion) of the outcome of interest, and d = precision [13]. Assuming a confidence level of 95% (corresponding to Z = 1.96) and a 4% rate of dispending PMs (P = 0.04) [14], in order to estimate the proportion of PMs dispensed in community pharmacies with a precision of 3%, the required sample size was 843 PMs.

2.4. Participants

Based on the required sample size, 16 pharmacies with 52 pharmacists were recruited to fill out the data reporting sheet over a period of 12 weeks. The selection of pharmacists was conducted to cover three regions in Jordan: Central and Capital region (Amman, Zarqa, Madaba, and Balqa), Northern region (Jerash, Irbid, Ajloun, Mafraq), and Southern region (Tafelah, Karak, Aqaba, Maan).

The inclusion criteria of pharmacies were as follows: opening at least two shifts per day and working regularly, being located near clinics, preferably those with psychiatrists, and having at least two licenced pharmacists present per shift practicing for at least one year. The pharmacies unwilling to participate were excluded. Pharmacists were given induction training on the study procedure and data collection form; this included types of medications prescribed/dispensed, and terminologies related to medication safety and pharmacist intervention classification.

2.5. Statistical Analysis

Data analysis was performed using SPSS version 26 [15]. In this study, the Shapiro–Wilk test was used, which showed that the collected data were normally distributed (p > 0.05). We reported any statistically significant differences employing the Chi-square test for categorical variables, and the independent t-test was used for continuous variables. We used regression analysis to examine how various independent variables related to a dependent variable. In this analysis, the dependent variable was categorized as either the appropriate or inappropriate prescription of PMs. A multidisciplinary committee categorized the inappropriate prescription of PMs into categories of overprescribing (the prescription of a medication for which no clear clinical indication exists), underprescribing (the omission of a potentially beneficial medication clinically indicated for the treatment or prevention of a disorder), inappropriate medication choice, inappropriate duration of medication therapy, and inappropriate medication dosage or frequency. This categorization, adopted from a previous study [16], helped us understand how different predictors influenced the likelihood of certain PM prescription practices being adopted.

3. Results

During the study period, 469 prescriptions containing 919 PMs were recorded. Among the prescribed PMs, 178 (19.4%) were inappropriately prescribed, and 723 were dispensed by the pharmacists (Table 1). The top three therapeutic categories prescribed were anti-epileptics (220, 23.9%), tranquillizers (105, 10.4%), and selective serotonin reuptake inhibitor (ssri) antidepressants (101, 11.0%); conversely, the least frequently prescribed categories were barbiturate plain hypnotics (14, 1.5%), non-barbiturate plain hypnotics (21, 2.3%), and nootropics (25, 2.7%).

As shown in Table 2, the highest number of PMs requested was for patients aged 52 years, with 41 PMs, followed by patients aged 25, with 40 PMs; conversely, the lowest level (2 PMs) was for patients aged 75 years.

In this study, the most common PMs prescribed were pregabalin (81, 8.8%), carbamazepine (74, 8.1%), Levetiracetam (69, 7.5%), and Clonazepam (67, 7.3%). On the other hand, the least common PMs prescribed were cyanocobalamin (6, 0.7%) and venlafaxine (7, 0.8%) (Table 3).

In our study, 178 PMs were inappropriately prescribed. The inappropriate prescription categories were overprescribing (45, 25.3%), underprescribing (19, 10.7%), inappropriate medication choice (39, 21.9%), an inappropriate duration of medication therapy (64, 36.0%), and inappropriate medication dosage (11, 6.2%) (Table 4).

Of the 2799 pharmacist interventions conducted during the study, 1023 (36.5%) were related to patient education, 362 (12.9%) were about asking for more clarification from the patient, and 214 (7.6%) involved changing the brand name of the medication prescribed (Table 5).

Among the patient education recommendations, 313 (30.6%) highlighted potential side effects, 163 (15.9%) explained the importance of medication adherence, and 122 (11.9%) were about advising the patient on lifestyle modifications that can support their mental health (Table 6).

The logistic regression model showed that physicians in the Central and Capital region were less likely to prescribe PMs inappropriately compared with those in the Northern region (AOR: 0.71; 95%CI: 0.01–0.87, p = 0.001) (Table 7). In addition, patients aged below 55 were more likely to be inappropriately prescribed PMs compared with those above 55 years (AOR: 1.75; 95%CI: 1.13–4.56, p = 0.018). Furthermore, the findings showed that SNRI antidepressants were less likely to be inappropriately prescribed compared with anti-epileptics (AOR: 0.62; 95%CI: 0.08–0.91, p = 0.014).

4. Discussion

While community pharmacists play an integral role in ensuring the safe use of PMs, research focusing on them remains lacking. This knowledge gap illustrates why urgent steps must be taken to investigate and develop evidence-based practices that empower community pharmacists to enhance patient outcomes within community settings. Therefore, this study aimed to investigate the pattern of PM prescription in primary care in Jordan, focusing on the appropriateness of prescription as well as the characteristics of pharmacists’ interventions in community pharmacies.

While limited to the pharmacies sampled, the frequent prescription of PMs observed in this study may reflect the high prevalence of treated mental disorders within the specific regions of Jordan included in our analysis. While there has been no study addressing this problem in the community sector of Jordan, there was a small study that reviewed each medical record of 67 patients with psychiatric disorders that found a high rate of prescriptions for PMs [17]

Our results coincided with previous research suggesting that antiepileptics, tranquillizers, and selective serotonin reuptake inhibitor (SSRI) antidepressants were the most common drugs prescribed to combat anxiety and major depressive disorders. These results backed what was known and proved the effectiveness of PMs for managing mental disorders. PMs were mostly prescribed to those aged between 52 years and 25 years, which indicated that they might be more vulnerable to mental health disorders. This finding was confirmed by the existing literature that emphasized the vulnerability to particular types of disorders during life stages. The population aged between 18 and 29 years have been identified with the highest prevalence rate of anxiety disorders, while those from 45 to 64 years old are more susceptible to depression [18]. Another research from Latin America [19] found that the highest number of PMs was prescribed for people at the age of 58. To develop age-tailored treatment plans and interventions, it is necessary to consider the variations that may only be applicable to these groups.

This alarming finding of a high inappropriate prescription incidence in our study (19.4%) was an issue that warranted prompt targeted action. This evidence almost paralleled the results from other countries that established an upsurge of PM prescription for psychiatric disorders management [20]. In a Norwegian study [20], the inappropriate prescription of PMs, based on the prescribing quality indicators, was compared in three Norwegian nursing homes in 2000 and 2016 and it was found that the potential inappropriate prescription of PMs increased from 0.8% to 27.9%.

Regarding the possible causes of inappropriate prescription by healthcare professionals, one possible explanation is that some professionals might have a wrong or outdated understanding of mental health disorders and pharmacological management guidelines. The other explanation could be that there were many patients with no access to specialized mental healthcare clinics, where they had to refer to non-psychiatrists.

Our findings showed that providers’ location, patients’ age, and the type of PMs predicted the occurrence of inappropriate prescription. In detail, inappropriate prescription was lower in the Central and Capital region than in the Northern region, possibly reflecting the variation among physicians in Jordan with respect to the availability of mental health teaching resources, physicians’ level of training, and cultural attitudes towards mental illnesses.

Furthermore, younger patients were more likely to be prescribed PMs inappropriately than those older than 55 years. This may reveal that younger people may administer PMs more frequently and incorrectly for a variety of reasons, including family pressure on physicians to prescribe PMs to control their children’s challenging behaviours.

Furthermore, the fact that SNRI antidepressants were less likely to be prescribed inappropriately than anti-epileptics may indicate that certain PMs might be more prone to misuse by physicians than others based on factors such as the safety profile of the medication, the availability of alternative treatment options, or clinical guidelines for treating mental health conditions.

These factors aligned somewhat with previous studies from other countries. One study conducted in the US found that older age, “seen before” status, and antidepressant drug class were factors making one less likely to have PMs prescribed inappropriately, while enrollment in Medicaid, antipsychotic drug class, living in the Northeast region, and receiving healthcare in a metropolitan area were negatively associated with PM prescription [21].

The findings of our study indicated that pharmacists performed a high number of interventions on prescriptions with PMs, which underscored the evolving role of community pharmacists in mental health. Additionally, there were three major types of interventions, namely patient education, asking for more clarifications from patients, and changing the brand name of prescribed medications.

Pharmacists’ roles in mental health have been shown to have positive effects, leading to improved prescribing practices and satisfaction among those living with mental illness [22]). Nonetheless, studies are often of low quality, necessitating well-designed randomized controlled trials (RCTs) that not only demonstrate effectiveness but also assess cost-effectiveness in different healthcare settings, including the community, hospitals, and others [22,23].

Studies have demonstrated the efficacy of pharmacist-led interventions in improving antidepressant medication adherence through education and monitoring [24,25]. Some studies investigated screening mental illnesses by pharmacists; investigations included perinatal depression screening as well as pilot studies, showing their feasibility [26,27].

A recent systematic review on pharmacist-led depression screening practices among adults found that they could use screening tools to detect undiagnosed depression in adult populations; however, more robust and high-quality research in this area should be conducted in order to ascertain cost-effectiveness and the clinical implications of such screening practices [28].

5. Conclusions

This study investigated the prescription patterns and appropriateness of PMs in primary care in Jordan. To sum up, our study revealed high rates of the prescription of potentially inappropriate PMs, indicating a concerning trend. Patient age, the location of the clinic, and drug class were associated with inappropriate prescription. Pharmacist interventions were frequently documented.

The strengths of this study came from its uniqueness, as there have been no studies investigating the frequency, types, and appropriateness of PMs in primary care in the region. One more strength was the observational nature of this study, which added to the validity of the findings. However, the study had some limitations. The data collection relied on pharmacist reporting and was potentially subject to recall bias or selective reporting, where pharmacists may have been more inclined to document interventions or problematic prescriptions. Prescriptions without interventions or issues may have been under-reported, potentially overestimating the rate of inappropriate prescription. While training was provided to pharmacists on using the data collection form, variations in interpretation and documentation practices cannot be ruled out.
