Novel opportunities for clinical pharmacy research: development of a machine learning model to identify medication related causes of delirium in different patient groups

The advent of artificial intelligence (AI) technologies has taken the world of science by storm in 2023. The opportunities of this easy to access technology for clinical pharmacy research are yet to be fully understood. The development of a custom-made large language model (LLM) (DELSTAR) trained on a wide range of internationally recognised scientific publication databases, pharmacovigilance sites and international product characteristics to help identify and summarise medication related information on delirium, as a proof-of-concept model, identified new facilitators and barriers for robust clinical pharmacy practice research. This technology holds great promise for the development of much more comprehensive prescribing guidelines, practice support applications for clinical pharmacy, increased patient and prescribing safety and resultant implications for healthcare costs. The challenge will be to ensure its methodologically robust use and the detailed and transparent verification of its information accuracy.

General practitioners-community pharmacists pharmacotherapy discussion groups: Analysis of their implementation through a series of case studies

Background

The evolution of primary care practice has led to the implementation of pharmacotherapy discussion groups between general practitioners and community pharmacists (PPPDGs) in some countries. The aim of these groups is to improve drug prescribing practices and strengthen interprofessional relationships.

Objective

To gain more insight into factors involved in successful implementation of PPPDGs.

Methods

PPPDG implementation in three countries (Belgium, the Netherlands, Switzerland), was analyzed in a series of case studies. A grid describing different evaluation criteria was completed by stakeholders in their respective country. The data collection was followed by a literature review.

Results

Various models were used to implement PPPDGs within each country and different dynamics were encountered. PPPDGs lead to positive effects on the quality and cost-effectiveness of drug prescribing and on the collaboration between general practitioners (GPs) and community pharmacists (CPs). Factors involved in implementation were also identified, such as expectations of GPs and CPs, configuration of the implemented model, and the role of CPs in the healthcare organization.

Conclusions

This study provides insight into the factors involved in successful implementation of PPPDGs in Belgium, the Netherlands and Switzerland. The findings can be used by healthcare professionals to improve the safety, cost-effectiveness of drug prescriptions and systems in primary care. This study offers a starting point for further research in the field.

Quality of Drug Prescribing and Dispensing Practices in Primary Healthcare Centres in an Urban Local Government Area in Nigeria

BACKGROUND

Irrational drug use remains a major issue in developing countries; hence this study used the World Health Organization and the International Network for the Rational Use of Drugs (WHO/INRUD) core drug indicators to assess the quality of prescribing and dispensing practices in Primary Health Centres (PHCs) in Obio-Akpor Local Government Area (LGA) in Nigeria.

METHODS

This descriptive cross-sectional study which covered 10 PHCs in Obio-Akpor LGA comprised a review of prescription records and a survey of patients and prescribers. A systematic random sample approach was used to retrieve 1300 prescriptions from August to October 2021 to evaluate prescribing indicators while direct observation of 325 consecutive patient encounters in the PHCs was used to evaluate the patient-care indicators. Twenty-three prescribers in the 10 PHCs who were available and willing to participate in the study, completed the self-administered questionnaire for assessment of the factors affecting prescribing practices. Descriptive and inferential analyses were done using the Statistical Package for the Social Sciences and p-values d" 0.05 were considered statistically significant.

RESULTS

From the 1300 retrieved prescriptions, a total of 3805 medications were prescribed for the 1300 encounters giving 2.9 (± 0.5) as the mean medications prescribed per encounter. Prescriptions in generic forms were 69.9% and 75.6% of drugs prescribed were from the Nigeria essential medicine list for PHCs. Encounters with antibiotics and injectables included in the prescriptions were 62.6% and 22.3% respectively. Antimalarial, antihypertensive, and antidiabetic medications were prescribed in 43.8 %, 9.6 %, and 1.7 % of the cases, respectively. Most (91.6 %) of the recommended drugs were dispensed, 98.2% of the drugs dispensed were appropriately labelled, and 95.5 % of the patients had an adequate understanding of their drug doses. The pharmacy stocked 88.7% of the key medications, and all PHCs had a copy of the EDL.

CONCLUSION

There was evidence of irrational drug use practices in PHCs in Obio-Akpor LGA. This calls for the implementation of periodic training for PHC workers, the promotion of effective monitoring and adherence to the policy of rational drug use in PHCs.

The WHO High 5s project: medication reconciliation in a German university hospital. A prospective observational cohort study

BACKGROUND

Ensuring medication accuracy during transitions in care is one of the five highly prevalent patient safety problems focused on within the World Health Organization High 5s Project. Medication reconciliation is a standardized patient care process that can be used to address this problem. The aim of the current study is to implement medication reconciliation in a German university hospital.

METHODS

The study was conducted at the Emergency Department of the University Hospital Aachen, Germany. All discrepancies between the Best Possible Medication History and the Admission Medication Order were documented and classified as documentation errors or medication errors. The type of error was also recorded. A negative binomial regression model was used to test several factors influencing the number of discrepancies.

RESULTS

The medications of 105 patients were reconciled. The mean number of discrepancies per patient was 4.6± 3.6, with a total of 298 medication errors and 189 documentation errors. The most common type of medication error was the omission of a drug (n=208; 69.8 %). In the negative binomial regression analysis, the care status (p=0.0015) as well as the number of preadmission drugs (p=0.0007) were significantly associated with medication errors.

DISCUSSION

A high number of discrepancies was detected and analysed. Patients admitted from nursing homes were less likely to have discrepancies in their medication reconciliation, perhaps because a structured documentation system for medications is already in place at nursing homes including error prone products (special dosage forms or food supplements).

CONCLUSIONS

In this study, medication reconciliation was implemented at a German full-care university hospital. The actual number of discrepancies observed strongly indicates the need for medication reconciliation at hospital admission.

A simulation-based module in pharmacology education reveals and addresses medical students' deficits in leading prescription talks

Although doctor-patient communication is essential for drug prescription, the literature reveals deficits in this area. An educational approach at the Cologne medical faculty aims at identifying and addressing those deficits in medical students.Fifth-year medical students first conducted a simulated prescription talk spontaneously. Subsequently, the conversation was discussed with peer students. A pharmacist moderated the discussion based upon a previously developed conversation guide. Afterwards, the same student had the conversation again, but as if for the first time. Conversations were video-recorded, transcribed and subjected to quantitative content analysis. Four days after the simulation, the students who conducted the talk, those who observed and discussed it, and students who did neither, completed a written test that focused on the content of an effective prescription talk.Content analysis revealed clear deficits in spontaneously led prescription talks. Even essential information as on adverse drug reactions were often lacking. Prescription talks became clearly more informative and comprehensive after the short, guided peer discussion. With regard to a comprehensive, informative prescription talk, the written test showed that both the students who conducted the talk and those who only observed it performed clearly better than the students who did not participate in the educational approach.Deficits regarding prescription talks are present in 5^th year medical students. We provide an approach to both identify and address these deficits. It thus may be an example for training medical students in simulated and clinical environments like the EACPT recommended to improve pharmacology education.

A mixed methods study on medicines information needs and challenges in New Zealand general practice

BACKGROUND

Medicines are central to healthcare in aging populations with chronic multi-morbidity. Their safe and effective use relies on a large and constantly increasing knowledge base. Despite the current era of unprecedented access to information, there is evidence that unmet information needs remain an issue in clinical practice. Unmet medicines information needs may contribute to sub-optimal use of medicines and patient harm. Little is known about medicines information needs in the primary care setting. The aim of this study was to investigate the nature of medicines information needs in routine general practice and understand the challenges and influences on the information-seeking behaviour of general practitioners.

METHODS

A mixed methods study involving 18 New Zealand general practitioner participants was undertaken. Quantitative data were collected to characterize the medicines information needs arising during 642 consultations conducted by the participants. Qualitative data regarding participant views on their medicines information needs, resources used, challenges to meeting the needs and potential solutions were collected by semi-structured interview. Integration occurred by comparison of results from each method.

RESULTS

Of 642 consultations, 11% (n = 73/642) featured at least one medicines information need. The needs spanned 14 different categories with dosing the most frequent (26%) followed by side effects (15%) and drug interactions (14%). Two main themes describing the nature of general practitioners' medicines information needs were identified from the qualitative data: a 'common core' related to medicine dose, side effects and interactions and a 'perplexing periphery'. Challenges in the perplexing periphery were the variation in information needs, complexity, 'known unknowns' and 'unknown unknowns'. Key factors affecting general practitioners' strategies for meeting medicines information needs were trust in a resource, presence of the patient, how the information was presented, scarcity of time, awareness of the existence of a resource, and its accessibility.

CONCLUSIONS

General practitioners face challenges in meeting wide-ranging medicines information needs in patients with increasingly complex care needs. Recognising the challenges and factors that influence resource use in practice can inform optimisation of medicines information support resources. Resources for general practitioners must take into account the complexity and time constraints of real-world practice. An individually responsive approach involving greater collaboration with pharmacists and specialist medicines information support services may provide a potential solution.

Tanzanian primary healthcare workers' experiences of antibiotic prescription and understanding of antibiotic resistance in common childhood infections: a qualitative phenomenographic study

Background

Antibiotic resistance is a threat to global child health. Primary healthcare workers play a key role in antibiotic stewardship in the community, but few studies in low-income countries have described their experiences of initiating antibiotic treatment in children. Thus, the present study aimed to describe primary healthcare workers’ experiences of antibiotic prescription for children under 5 years of age and their conceptions of antibiotic resistance in Northern Tanzania.

Methods

A qualitative study involving individual in-depth interviews with 20 prescribing primary healthcare workers in Moshi urban and rural districts, Northern Tanzania, was performed in 2019. Interviews were transcribed verbatim, translated from Kiswahili into English and analysed according to the phenomenographic approach.

Findings

Four conceptual themes emerged during the analysis; conceptions in relation to the prescriber, the mother and child, other healthcare actors and in relation to outcome. The healthcare workers relied mainly on clinical examination and medical history provided by the mother to determine the need for antibiotics. Confidence in giving advice concerning non-antibiotic treatment varied among the participants and expectations of antibiotic treatment were perceived to be common among the mothers. Antibiotic resistance was mainly perceived as a problem for the individual patient who was misusing the antibiotics.

Conclusions

To increase rational antibiotic prescription, an awareness needs to be raised among Tanzanian primary healthcare workers of the threat of antibiotic resistance, not only to a few individuals, but to public health. Guidelines on childhood illnesses should be updated with advice concerning symptomatic treatment when antibiotics are not necessary, to support rational prescribing practices and promote trust in the clinician and mother relationship.

Aspects of Medication and Patient participation-an Easy guideLine (AMPEL). A conversation guide increases patients' and physicians' satisfaction with prescription talks

Patients want more information and active participation in medical decisions. Information and active participation correlate with increased adherence. A conversation guide, combining patient-relevant drug information with steps of shared decision-making, was developed to support physicians in effective and efficient prescription talks. Six GP trainees in community-based primary care practices participated in a controlled pilot study in sequential pre-post design. Initially, they conducted 41 prescription talks as usual, i.e., without knowing the guide. Then, they conducted 23 talks considering the guide (post-intervention phase). Immediately after the respective talk, patients filled in a questionnaire on satisfaction with the information on medication and physician–patient interaction, and physicians about their satisfaction with the talk and the application of the guide. Patients felt better informed after guide-based prescription talks (e.g., SIMS-D in median 10 vs. 17, p < 0.05), more actively involved (KPF-A for patient activation 2.9 ± 0.8 vs. 3.6 ± 0.8, p < 0.05), and more satisfied with the physician–patient interaction. Physicians rated the guide helpful and feasible. Their satisfaction with the conversation was significantly enhanced during the post-intervention phase. The evaluation of the duration of the talk was not influenced. Enhanced patients’ and physicians’ satisfaction with prescription talks encourages further examinations of the conversation guide. We invite physicians to try our guide in everyday medical practice.

Off-Label Use and Safety of Drug Use in Vascular Anomalies

BACKGROUND

Off-label drug use is associated with an increased risk of adverse drug reactions. It is common in pediatrics and in rare diseases, which are two characteristics applying to vascular anomalies (VA).

OBJECTIVES

The aim of this work was to quantify off-label drug use in VA and assess its safety.

METHODS

A review was conducted to extract a list of drugs used in VA management. A drug was considered to have significant safety concerns if a black box warning was present or if a serious adverse drug reaction (SADR) was reported in at least 1% of the patients (SADR is defined as a noxious and unintended response to a drug that occurs at any dose and results in hospitalization, prolongation of existing hospitalization, congenital malformation, persistent or significant disability or incapacity, life-threatening condition, or death). The labelling status and safety of each drug was assessed based on the product monograph, Micromedex, and the FDA data.

RESULTS

We found that 98.9% of the inventoried drugs were used off-label or unlicensed for VA management. Only the oral solution of propranolol hydrochloride (Hemangeol®) for the treatment of infantile hemangiomas is approved. Significant safety issues concerned 73% of the drugs and were more frequent among systemic than locally delivered drugs.

CONCLUSIONS

Off-label drug use in VA is the rule and not the exception. Significant safety concerns are common. It is necessary to carefully weigh risk and benefits for every patient when using systemic and local treatments carrying safety concerns. Patients should be openly informed and involved in the decision-making process.

Do computerized clinical decision support systems improve the prescribing of oral anticoagulants? A systematic review

BACKGROUND

Serious adverse drug reactions have been associated with the underuse or the misuse of oral anticoagulant therapy. We systematically reviewed the impact of computerized clinical decision support systems (CDSS) on the prescribing of oral anticoagulants and we described CDSS features associated with success or failure.

METHODS

We searched Medline, Embase, CENTRAL, CINHAL, and PsycINFO for studies that compared CDSS for the initiation or monitoring of oral anticoagulants with routine care. Two reviewers performed study selection, data collection, and risk-of-bias assessment. Disagreements were resolved with a third reviewer. Potentially important CDSS features, identified from previous literature, were evaluated.

RESULTS

Sixteen studies were included in our qualitative synthesis. Most trials were performed in primary care (n = 7) or hospitals (n = 6) and included atrial fibrillation (AF) patients (n = 9). Recommendations mainly focused on anticoagulation underuse (n = 11) and warfarin-drug interactions (n = 5). Most CDSS were integrated in electronic records or prescribing and provided support automatically at the time and location of decision-making. Significant improvements in practitioner performance were found in 9 out of 16 studies, while clinical outcomes were poorly reported. CDSS features seemed slightly more common in studies that demonstrated improvement.

CONCLUSIONS

CDSS might positively impact the use of oral anticoagulants in AF patients at high risk of stroke. The scope of CDSS should now evolve to assist prescribers in selecting the most appropriate and tailored medication. Efforts should nevertheless be made to improve the relevance of notifications and to address implementation outcomes.

Medication use in older patients and age-blind approach: narrative literature review (insufficient evidence on the efficacy and safety of drugs in older age, frequent use of PIMs and polypharmacy, and underuse of highly beneficial nonpharmacological strategies)

INTRODUCTION

The importance of rational drug therapy is increasing with the aging of the population. Since one of the main reasons for inappropriate drug prescribing is also the "age-blind" approach, which results in ageist practices, this narrative literature review focuses on the description of the main barriers related to insufficient individualization of drug regimens associated with such age-blind approaches.

METHODOLOGY

A narrative literature review using the PubMed, WoS, Embase, and Scopus databases was conducted by the EU COST Action IS1402. Experts in different scientific fields from six countries (the Czech Republic, Spain, Portugal, Hungary, Serbia, and Turkey) worked in four specific areas: (1) underrepresentation of older adults in clinical trials and clinical and ethical consequences; (2) insufficient consideration of age-related changes and geriatric frailty in the evaluation of the therapeutic value of drugs; (3) frequent prescribing of potentially inappropriate medications (PIMs); and (4) frequent underuse of highly beneficial nonpharmacological strategies (e.g., exercise).

RESULTS

Older patients are underrepresented in clinical trials. Therefore, rigorous observational geriatric research is needed in order to obtain evidence on the real efficacy and safety of frequently used drugs, and e.g. developed geriatric scales and frailty indexes for claims databases should help to stimulate such research. The use of PIMs, unfortunately, is still highly prevalent in Europe: 22.6% in community-dwelling older patients and 49.0% in institutionalized older adults. Specific tests to detect the majority of age-related pharmacological changes are usually not available in everyday clinical practice, which limits the estimation of drug risks and possibilities to individualize drug therapy in geriatric patients before drug prescription. Moreover, the role of some nonpharmacological  strategies is highly underestimated in older adults in contrast to frequent use of polypharmacy. Among nonpharmacological strategies, particularly physical exercise was highly effective in reducing functional decline, frailty, and the risk of falls in the majority of clinical studies.

CONCLUSION

Several regulatory and clinical barriers contribute to insufficient knowledge on the therapeutic value of drugs in older patients, age-blind approach, and inappropriate prescribing. New clinical and observational research is needed, including data on comprehensive geriatric assessment and frailty, to document the real efficacy and safety of frequently used medications.

Adequate, questionable, and inadequate drug prescribing for older adults at the end of life: a European expert consensus

Background

Clinical guidance is needed to initiate, continue, and discontinue drug treatments near the end of life.

Aim

To identify drugs and drug classes most often adequate, questionable, or inadequate for older people at the end of life.

Design

Delphi consensus survey.

Setting/participants

Forty European experts in geriatrics, clinical pharmacology, and palliative medicine from 10 different countries. Panelists were asked to characterize drug classes as “often adequate,” “questionable,” or “often inadequate” for use in older adults aged 75 years or older with an estimated life expectancy of ≤ 3 months. We distinguished the continuation of a drug class that was previously prescribed from the initiation of a new drug. Consensus was considered achieved for a given drug or drug class if the level of agreement was ≥ 75%.

Results

The expert panel reached consensus on a set of 14 drug classes deemed as “often adequate,” 28 drug classes deemed “questionable,” and 10 drug classes deemed “often inadequate” for continuation during the last 3 months of life. Regarding the initiation of new drug treatments, the panel reached consensus on a set of 10 drug classes deemed “often adequate,” 23 drug classes deemed “questionable,” and 23 drug classes deemed “often inadequate”. Consensus remained unachieved for some very commonly prescribed drug treatments (e.g., proton-pump inhibitors, furosemide, haloperidol, olanzapine, zopiclone, and selective serotonin reuptake inhibitors).

Conclusion

In the absence of high-quality evidence from randomized clinical trials, these consensus-based criteria provide guidance to rationalize drug prescribing for older adults near the end of life.

Renal transplant patients' preference for the supply and delivery of immunosuppressants in Wales: a discrete choice experiment

BACKGROUND

Prescribing policy recommendations aimed at moving immunosuppressant prescribing for renal transplant patients from primary to secondary care may result in benefits of increased safety and reduced cost. However, there is little evidence of patients' preferences for receiving their immunosuppressant therapy from hospitals compared to community dispensing. The aim of this study was to elicit patient preferences for different service configurations focusing in particular on home delivery versus collection of medication from hospital.

METHODS

A discrete choice experiment was administered to 265 renal transplant patients in North Wales. Respondents were presented 18 pairwise choices, labelled as either home delivery or hospital collection, and described by the attributes: frequency of supply, waiting time (for delivery or collection) and method of ordering (provider contact, patient contact via phone, patient contact electronically). Data were analysed using a random-effects logit model and marginal rates of substitution calculated based on the waiting time attribute.

RESULTS

A response rate of 63% was achieved, with 5332 usable observations from 150 respondents. Method of delivery (β coefficient 1.21; 95% confidence interval 1.05 to 1.38), frequency of supply (0.05; 0.03 to 0.08) waiting time (-0.00, -0.00 to -0.00), provider contact (desirable) (0.20; 0.12 to 0.27), patient contact by telephone (desirable) (0.09; 0.01 to 0.17) and patient contact electronically (undesirable) (-0.292; -0.37 to -0.21) were statistically significant (p < 0.05). Results indicate that patients are willing to increase waiting time by nearly 10 h to have a home delivery service.

CONCLUSION

Patients indicate a clear preference for a home delivery service. They prefer providers to make contact when new immunosuppressant supplies are required and show preference against ordering medication electronically. A policy for secondary care prescribing and hospital collection of medicines does not align with this preference.

Antipsychotic prescribing for Alzheimer's disease and related disorders in specialized settings from 2010 to 2014 in France: a repeated cross-sectional study

BACKGROUND

Safety warnings from health authorities are currently intended to limit the use of antipsychotics (APs) in dementia-related conditions to treat neuropsychiatric symptoms, such as disturbing and/or delusional behaviors. The aim of this study is to investigate prevalence, correlates and trends of AP prescribing among people with dementia between 2010 and 2014 in the French population.

METHODS

AP prescribing and associated factors among individuals with AD, mixed dementia and vascular dementia in the French National Alzheimer Database between 2010 and 2014 were analyzed using multivariate generalized estimating equations models (n = 199,549).

RESULTS

In 2014, 7.7% of people with dementia were prescribed an AP. Compared with 2010 there was a 16% increase in AP use. Multivariate analysis showed a linear increase risk of prescription with an adjusted odds ratio (95% confidence interval) of 1.23 (1.17-1.30) in 2014 compared with 2010. Factors associated with AP prescribing were male gender, more severe cognitive decline and living in long-term care facilities. Older age and higher education were protective toward AP prescribing. The type of dementia did not have any influence on AP prescribing.

CONCLUSION

An increase in AP prescribing among individuals with dementia in French specialized settings over the last 5 years occurred despite safety warnings. This phenomenon suggests that alternative solutions for the management of behavioral and psychiatric symptoms in these populations are still urgently needed.

Awareness of Mothers and Doctors about Drug Utilization Pattern for Illnesses Encountered during Pregnancy

BACKGROUND

Careful consideration of the benefit to the mother and risk to the foetus, is required, while prescribing drugs during pregnancy.

OBJECTIVES

To assess the pattern of drug utilization during pregnancy and to explore the knowledge, attitude and awareness on drug use by the antenatal mother in a tertiary care hospital setup in western India.

MATERIAL AND METHODS

Observational, cross-sectional study involved holding interviews on 501 pregnant women, in OPD and IPD of Obstetrics-Gynaecology Department using a pilot-based questionnaire, was done. Data from prescriptions and case-files were also collected. Drugs were classified pharmacologically and according to teratogenic potential using U.S.FDA classification. Study population was classified according to the trimester of pregnancy and educational and socioeconomic status. Intergroup comparison was done using Chi-square test.

RESULTS

Majority of the drugs were from Category A(71.2%) and Category B (16.5%), followed by those from Categories C(9.09%), D(1.12%) and X(0.7%). Category A drugs were significantly used more in first trimester, while Category C and D drugs were used in the last two trimesters (p<0.0001) for pregnancy associated complications. Only 24.55% of the women believed that drug use in pregnancy could be harmful to both mother and baby, while 35.52% believed that drug use could be dangerous throughout pregnancy. Patients' educational and socio-economic statuses influenced their compliance for nutritional supplements prescribed during pregnancy and their awareness on common contraceptive methods. Higher education and socioeconomic class provided information on safety of barrier contraception during pregnancy.

CONCLUSION

Study revealed careful prescribing behaviour of physicians. Lack of awareness on safety of drugs in pregnancy and contraceptive use advocates a need for educating and counselling women of child bearing ages.
