Non-prescription supply of combination analgesics containing codeine in community pharmacy: A simulated patient study

Counselling with a focus on product and price transparency for over-the-counter headache medicines: A simulated patient study in community pharmacies in Munich, Germany

BACKGROUND

In Germany, over-the-counter (OTC) medicines may only be dispensed by community pharmacies (CPs). German CPs must ensure 'adequate' counselling, including the cost of medicines. Along with information gathering and advice giving as classic aspects of counselling, the aim was also to investigate counselling indicators of product and price transparency.

METHODS

The cross-sectional study was based on the covert simulated patient (SP) methodology and was conducted in a random sample of CPs stratified by districts in the major German city of Munich. Each of the 178 selected CPs was visited once by one of five trained female students. They simulated a symptom-based sub-scenario 1 with a request for an OTC medicine for a headache and a sub-scenario 2 with standardised information regarding product and price transparency. The assessment, completed immediately postvisit by the SPs, included a total of 23 items.

RESULTS

All 178 scheduled visits were completed successfully. The median counselling score with the classic items was 3.0 out of 12 points (interquartile range [IQR] 4.25) and when expanded by items for product and price transparency the score was 4.0 out of 14 points (IQR 4.00). A selection of medicines was offered unsolicited in 38.2% of the visits and in 5.6% of the visits voluntary price information was provided before the transaction. A request for a cheaper medicine led to a significant price reduction (Wilcoxon signed-rank test; p < 0.001, r = 0.869).

CONCLUSION

Due to the below-average level of counselling, the regional chambers of pharmacists are recommended to initiate measures for improvement. There is also potential for optimisation with regard to product and price transparency as an important extension of the classic counselling aspects. It is therefore recommended that the government raise customers' awareness of the cost of medicines.

Is there a need for standardization of medication counseling in community pharmacies?

Medication counseling is one of the most important duties in community pharmacies aiming to ensure rational pharmacotherapy and medication safety. However, based on research evidence, the quality of medication counseling in pharmacies is often low and shown to vary between different patient groups. This Commentary raises a question whether there is a need to standardize medication counseling in community pharmacies to ensure quality of care for every customer? The law obligates to counsel about medications when dispensing medicines in many countries, however, on a very general level. It seems clear that the general level in which medication counseling is required in law is not enough to ensure the quality of medication counseling, and thus, some standards are needed. However, these standards should take into account the multidisciplinary nature of the pharmacotherapy process as well as the different patient groups and situations that patients face. Most importantly, such standards should not inhibit interaction between the patient and the pharmacist, and they should encourage tailored medication counseling that is based on the individual needs of the patient.

Pharmacists' use of guidelines for the supply of non-prescription medicines: a cross-sectional survey

OBJECTIVES

Guidelines support best practice for healthcare practice. In Australia, some non-prescription medicines are only accessible after consultation with a pharmacist and are known as Pharmacist Only medicines. Guidelines for providing some Pharmacist Only medicines are available, however, it is currently unknown if and how these guidelines are used in practice.The objective was to characterise pharmacists', intern pharmacists and pharmacy students' use of guidelines for Pharmacist Only medicines.

METHODS

A cross-sectional electronic survey of Australian registered pharmacists, intern pharmacists and pharmacy students was administered in July 2020. Questions explored the participants' use of Pharmacist Only medicine guidelines (available both in print and online; available online only) in the preceding 12 months. Data were analysed descriptively (i.e. frequencies, percentages).

KEY FINDINGS

In total, 574 eligible respondents completed the survey. Overall, 396 (69%) reported accessing the online and in-print guidelines in the previous 12 months with 185 (33%) accessing online-only guidelines. The guideline on emergency contraception was used the most out of all guidelines in the past 12 months (278, 48%). Overall, respondents reported accessing guidelines to update knowledge, check their practice reflected best practice and content familiarisation. Respondents' reasons for not accessing guidelines were due to respondents stating they did not need the information or that they had previously accessed the guidelines more than 12 months ago. These reasons varied between respondent groups.

CONCLUSIONS

Access and use of the Pharmacist Only medicines guidelines varied between pharmacists, interns and students. Further understanding of the influences of the use of these guidelines will help inform professional bodies on how best to develop guidelines to increase consistent use in practice and implement interventions to increase use.

The quality of non-prescription medicine counselling in Finnish pharmacies - a simulated patient study

Background

Medication counselling provided by pharmacists is important for ensuring the safe use of medicines.

Objective

To assess the quality of non-prescription medicines counselling in Finnish pharmacies.

Methods

Three scenarios using simulated patient methodology were conducted: the patient requesting a specific brand name Burana® (ibuprofen, OTC medicine), Pronaxen® (naproxen, behind-the-counter (BTC) medicine) and a nasal spray. The visits were conducted in 146 pharmacies by trained simulated patients. Each pharmacy was visited twice. The quality of counselling was defined as poor (1-2 points), moderate (3-4 points), or high (5-6 points) based on developed scenario-based scoring criteria.

Results

The total number of conducted visits was 292, of which only 29 received high quality counselling. The quality was high in 20% of the cases for Pronaxen® and in 7% of the cases for Nasal spray scenarios. In the Burana® scenario, counselling quality was high only in 2% of the cases. Patients who requested a nasal spray were often asked questions about their symptoms (93%). In the Pronaxen®-scenario, the most frequently asked questions were related to contraindications and drug interactions (56%). The most often given instructions varied between the scenarios, being follow-up in the Burana® and Nasal spray scenarios (17% and 70%, respectively) and how to use the medicine in the Pronaxen®-scenario (63%).

Conclusions

Non-prescription medicine counselling is rarely performed with high quality. However, the quality of counselling depends on the medication in question. There is room to improve medication counselling and the assessment of the necessity and suitability of treatment, especially when a patient requests an OTC pain medicine by its brand name.

Practice of pharmaceutical care by community pharmacists in response to self-medication request for a cough: a simulated client study

BACKGROUND

Community pharmacy practice worldwide has been shifting from product-focused to patient-oriented. However, due to the absence of separation between prescribing and dispensing in Malaysia, community pharmacists may have limited roles in the provision of pharmaceutical care to patients with chronic diseases. Therefore, the main functions of community pharmacists in Malaysia are related to self-medication requests for minor ailments and the supply of non-prescription medications. The objective of this study was to determine the practice of pharmaceutical care by community pharmacists within the Klang Valley, Malaysia in response to self-medication requests for a cough.

METHODS

This study utilised a simulated client method. A research assistant, acting as a simulated client, visited community pharmacies in the Klang Valley, Malaysia to consult the pharmacists on the treatment of a cough experienced by his father. Upon leaving the pharmacy premise, the simulated client entered the pharmacist's responses in a data collection form which was structured based on pharmacy mnemonics for the response to symptoms, OBRA'90 on counselling elements, the five practice principles of pharmaceutical care by the American Pharmacists Association and literature review. Visits to the community pharmacies were conducted from September to October 2018.

RESULTS

The simulated client visited a total of 100 community pharmacies. None of these community pharmacists practised adequate patients' data collection, with only a low proportion who practised all the components studied under medication information evaluation (13%), formulating a drug therapy plan (15%) and monitoring and modifying the plan (3%). Of the 100 community pharmacists, 98 recommended treatment but none of them provided all the counselling elements studied in implementing the drug therapy plan.

CONCLUSION

The present study showed that community pharmacists within the Klang Valley, Malaysia were not providing adequate pharmaceutical care services to patients seeking self-medication for a cough. Such practice may compromise patient safety if inappropriate medicines or advice are given.

The Quality of Counseling for Headache OTC Medications in German Community Pharmacies Using a Simulated Patient Approach: Are There Differences between Self-Purchase and Purchase for a Third Party?

Background

In Germany—as worldwide—headache is one of the most frequent causes of self-medication. The dispensing of over-the-counter (OTC) medications may only be carried out by community pharmacies (CPs). In doing so, CPs have to ensure “adequate” counseling, for both self-purchase and purchase for a third party, which also occurs in everyday pharmacy practice. The aim of this study was to evaluate the quality of counseling for headache OTC medications in German CPs and, as the first study worldwide, to analyze whether and to what extent there are differences in counseling between self-purchase and purchase for a third party.

Methods

A cross-sectional study was carried out using the covert simulated patient methodology (SPM) in all 42 CPs in the German big city Potsdam. With the help of 8 trained simulated patients (SPs), each CP was visited four times by a different SP. The SPs simulated in each CP two scenarios two times with the demand for an OTC medication against headache, which differed only in whether the demand was for themselves or for their boyfriend/girlfriend.

Results

All 168 planned pharmacy visits (84 visits per scenario) were successfully carried out. Overall, the median counseling score was 3.0 out of 9 points (interquartile range [IQR 2.0]). There were no significant differences between the two scenarios (Wilcoxon signed-rank test; p=0.495, r = 0.053). In a multivariate binary logistic regression analysis, the counseling level and the different scenarios were not significantly associated (adjusted odds ratio [AOR] = 1.635, 95% CI = 0.673–3.972, p=0.278).

Conclusions

Due to the partly considerable deficits in counseling of German CPs, policy-makers and the regional chambers of pharmacists are called upon to take appropriate measures to improve the quality of counseling. It is positive that no differences in counseling between self-purchase and purchase for a third party were found, but further verifying studies with a modified methodology are recommended.

Do north-eastern German pharmacies recommend a necessary medical consultation for acute diarrhoea? Magnitude and determinants using a simulated patient approach

Background: In Germany, non-pharmacists (pharmacy technicians and pharmaceutical technical assistants) are permitted to advise on and sell medications in addition to pharmacists. The aim of this study was to determine if pharmacists and non-pharmacists referred patients to a medical consultation for a scenario in which consulting a doctor was mandatory ('appropriate outcome') and what the quality of questioning and - if a medication was dispensed - the quality of information provided were in this context. The study also aimed to determine which factors predicted a necessary referral to a doctor. Methods: A cross-sectional, covert simulated patient study was conducted in a random sample of community pharmacies stratified by location in the German state of Mecklenburg-Vorpommern. Each pharmacy was visited once by one of four trained investigators. They simulated a symptom-based request involving a grandmother with acute diarrhoea. A multivariate binary logistic regression analysis using potential variables from bivariate analysis was carried out to determine the predictors for a referral to a doctor. Results: All 199 planned visits were conducted. A necessary referral to a doctor was recommended in 59.8% (n=119) of all visits. The most commonly asked question was 'for whom is the medication?' (75.4%, n=150), while 'clarification by a doctor' was asked the least (17.6%, n=35). In 87.9% (n=175) of all visits a medication was dispensed. Multivariate analysis revealed that, unlike pharmacists, non-pharmacists have a 2.446 times higher likelihood of recommending a referral to a doctor (p = 0.044; 95% CI = 1.025-5.835). Conclusions: In almost half of the visits a necessary referral to a doctor was not recommended. Furthermore, the quality of questioning and the quality of information were below expectations. Moreover, involvement of non‑pharmacists was surprisingly identified as a relevant factor influencing the appropriate outcome.

Do north-eastern German pharmacies recommend a necessary medical consultation for acute diarrhoea? Magnitude and determinants using a simulated patient approach

Background: To determine if pharmacy staff in Germany referred patients to a medical consultation for a scenario in which consulting a doctor was mandatory (‘appropriate outcome’) and what the quality of questioning and – if a medication was dispensed – the quality of information provided were in this context. Moreover, to determine which factors predicted a necessary referral to a doctor. Methods: A cross-sectional covert simulated patient study was conducted in a random sample of community pharmacies stratified by location in the German state of Mecklenburg-Vorpommern. Each pharmacy was visited once by one of four trained investigators. They simulated a symptom-based request involving a grandmother with acute diarrhoea. A multivariate binary logistic regression analysis using potential variables from bivariate analysis was carried out to determine the predictors for a referral to a doctor. Results: All 199 planned visits were conducted. A necessary referral to a doctor was recommended in 59.8% (n=119) of all test purchases. Multivariate analysis revealed that a non-pharmacist as opposed to a pharmacist and two or more questions as opposed to no questions were significantly associated with a referral to a doctor. Conclusions: Regarding the necessary referral to a doctor, an enormous potential for improvement was revealed for community pharmacies in the German state of Mecklenburg-Vorpommern. The results should make both the Mecklenburg-Vorpommern pharmacy association and legislators aware of the need to significantly escalate their quality management efforts.

Medication dispensing, additional therapeutic recommendations, and pricing practices for acute diarrhoea by community pharmacies in Germany: a simulated patient study

Background:

In Germany over-the-counter medications (OTC) – which since 2004 are no longer subject to binding prices – can only be purchased in pharmacies. Pharmacy owners and their staff therefore have a special responsibility when dispensing, advising on and setting the prices of medications.

Objective:

The aim of this study was to assess medication dispensing, additional therapeutic recommendations and pricing practices for acute diarrhoea in adults and to evaluate the role of the patient’s approach (symptom-based versus medication-based request) in determining the outcome of these aspects.

Methods:

A cross-sectional study was conducted from 1 May to 31 July 2017 in all 21 community pharmacies in a medium-sized German city. Symptom-based and medication-based scenarios related to self-medication of acute diarrhoea were developed and used by five simulated patients (SPs) in all of the pharmacies (a total of 84 visits). Differentiating between the different test scenarios in terms of the commercial and active ingredient names and also the prices of the medications dispensed, the SPs recorded on collection forms whether the scenario involved generic products or original preparations as well as whether recommendations were made during the test purchases regarding an additional intake of fluids.

Results:

In each of the 84 test purchases one preparation was dispensed. However, a preparation for oral rehydration was not sold in a single test purchase. On the other hand, in 74/84 (88%) of test purchases, medications with the active ingredient loperamide were dispensed. In only 35/84 (42%) of test purchases, the patient was also recommended to ensure an ‘adequate intake of fluids’ in addition to being dispensed a medication. In symptom-based scenarios significantly more expensive medications were dispensed compared to the medication-based scenarios (Wilcoxon signed rank test: z = -4.784, p < 0.001, r = 0.738). Also within the different scenarios there were enormous price differences identified – for example, in the medication-based scenarios, even for comparable loperamide generics the cheapest preparation cost EUR 1.99 and the most expensive preparation cost EUR 4.53.

Conclusions:

Oral rehydration was not dispensed and only occasionally was an adequate intake of fluids recommended. There were also enormous price differences both between and within the scenarios investigated.

Pharmacists' views on the upscheduling of codeine-containing analgesics to 'prescription only' medicines in Australia

Background Codeine is the most commonly used opioid worldwide, and is available over-the-counter (OTC) in many countries. There is continual debate regarding the risk:benefit profile for OTC codeine. In Australia, codeine containing analgesics became 'prescription only medicine' from February 2018. However, there is currently limited knowledge on the views of community pharmacists on this upscheduling and the perceived impacts on clinical practice. Objective To investigate the views of community pharmacists on the recent codeine upscheduling in Australia. Setting Community pharmacists in Australia, predominately recruited from Victoria. Method A descriptive cross-sectional study was conducted using a pre-tested customised anonymous self-administered online questionnaire between March and May 2018. To capture a broad range of demographics, pharmacists were recruited via local industry contacts and the Pharmaceutical Society newsletter, with further recruitment through snowball sampling. Main outcome measure Pharmacists' opinions to targeted questions regarding the perceived advantages and disadvantages of the recent 2018 codeine rescheduling from both their perspectives and their perceived impact on patients. Results A total of 113 pharmacists completed the survey. Approximately 43% of pharmacists agreed/strongly agreed that they believed upscheduling will positively impact their ability to manage pain; while 30% were neutral. Approximately 54% of pharmacists agreed/strongly agreed that they believed upscheduling will positively benefit their patients; while 25% were neutral. Perceived advantages for codeine upscheduling included: increased pharmacist/patient engagement, and less codeine use leading to better overall risk:benefit outcome; while disadvantages included: fewer analgesic options, and increased burden for patients, General Practitioners, and the health system. Conclusion This study showed that the current views on the recent codeine upscheduling are quite mixed, with both advantages and disadvantages perceived. Improving education and up-skilling in this space is essential.

Investigating the management of potentially cancerous nonhealing mouth ulcers in Australian community pharmacies

We sought to examine the management and referral of nonhealing mouth ulcer presentations in Australian community pharmacies in the Greater Brisbane region. Trained simulated patients visited 220 randomly selected community pharmacies within the Greater Brisbane region in 2016. Simulated patients enacted two nonhealing (>1 month) mouth ulcer scenarios: A direct product request (DPR) (n = 110) and a symptom-based request (SBR) (n = 110). Results were documented and evaluated against Australian national pharmacy practice standards. Referral rates for pharmacy staff (pharmacist, pharmacy assistant or mixed-pharmacist and assistant) were also assessed. Australian pharmacy practice standards recommend staff ask six key questions during SBR and DPR consultations to enable informed decision-making. Two questions relating to identifying the patient and their symptoms were asked in the majority of interactions (76% and 69% respectively); the remaining four questions relating to symptom duration, treatments tried, other medications, and medical conditions were enquired in only 32%, 53%, 31%, and 27% of interactions, respectively. Simulated patients were referred to the doctor/dentist in only 11.8% of all interactions (both scenarios requiring referral). Overall, staff handling of nonhealing mouth ulcer consultations was suboptimal compared to national professional standards. In particular, duration of the nonhealing mouth ulcer was enquired in less than one-third of consultations potentially resulting in low referral rates by staff. This study identifies the need for increased oral cancer awareness and education for community pharmacy staff and reinforcing the importance of practising according to professional standards to effectively screen for potentially cancerous nonhealing mouth lesions.

A systematic review of community pharmacies' staff diagnostic assessment and performance in patient consultations

BACKGROUND

Increases in patients seeking advice at pharmacies has led to pharmacy staff engaging in diagnostic behaviours. Approaches to diagnosis include using mnemonics and clinical reasoning.

OBJECTIVES

The primary aim of this review was to assess the degree to which the criteria researchers use to evaluate diagnostic performance in pharmacy consultations, in studies that have simulated patients or vignettes, conform with a clinical reasoning and a mnemonic framework. A secondary aim of the review was to characterize staff performance in the studies, based on the authors' comments of their results.

METHODS

MEDLINE, EMBASE and Web of Science were searched between October 2016 and April 2017. Only peer-reviewed studies assessing pharmacy staff's diagnostic performance using simulated patients or vignettes were eligible for inclusion. Data were extracted about how each study's criteria conformed with clinical reasoning and mnemonic frameworks. A scoring system between 0 and 4 was devised to determine the degree to which studies aligned to these two approaches. Risk of bias was assessed using the NHI Study Quality Assessment Tools. The review was registered in PROSPERO with identification number CRD42017054827.

RESULTS

Sixty-eight studies (55 cross-sectional, 11 educational interventions and 2 RCTs) with sample sizes between 10 and 2700 were included in the review. Most studies were of poor or fair quality. Performance of pharmacy staff was overwhelmingly reported as poor by study authors. This was the case regardless of geography, scenario used, or assessment framework adopted. Scrutiny on how authors arrived at these conclusions revealed that mnemonic criteria were employed to assess pharmacy staff's diagnostic performance rather than a clinical reasoning approach.

CONCLUSIONS

Potentially important aspects of the decision-making process, such as clinical reasoning, were left unexplored. The number and geographic distribution of the included studies is a strength of this review; however, a validated tool was not employed.

Preparation, Characterization and Pharmacokinetics Evaluation of the Compound Capsules of Ibuprofen Enteric-Coated Sustained-Release Pellets and Codeine Phosphate Immediate-Release Pellets

The objective of this study was to prepare ibuprofen enteric-coated sustained-release pellets (IB-SRPs) and codeine phosphate immediate-release pellets (CP-IRPs) to play a synergistic role in analgesia. The pellets were developed by extrusion-spheronization and fluidized bed coating technology. The single-factor investigation was used to determine the optimal prescription and process. The sustained-release membrane of IB-SRPs was water-insoluble ethyl cellulose (EC), triethyl citrate (TEC) was used as plasticizer, and hydroxypropyl methylcellulose (HPMCP) was chose as porogen. Besides, the immediate-release layer of CP-IRPs was gastric-soluble coating film. The ibuprofen and codeine phosphate compound capsules (IB-CP SRCs) were prepared by IB-SRPs and CP-IRPs packed together in capsules with the optimum doses of 200 and 13 mg, respectively. The prepared pellets were evaluated by scanning electron microscopy and dissolution test. Pharmacokinetic studies in beagle dogs indicated that the optimized IB-CP SRCs had smaller individual differences and better reproducibility comparing with commercial available tablets. Additionally, IB-CP SRCs achieved consistency with in vivo and in vitro tests. Therefore, IB-CP SRCs could play a great role in rapid and long-term analgesic.
