Italian drug information centres: benchmark report

Clinical-pharmacological drug information center of Hannover Medical School: experiences and analysis from a tertiary care university hospital

Drug information centers (DICs) are institutions dedicated to provide objective, independent, and up-to-date information on drugs and their rational use. To overcome the lack of recent DIC reports from central Europe, we analyzed all queries (n = 594) submitted to the DIC run by the Institute for Clinical Pharmacology of Hannover Medical School between October 2018 and April 2022. Approximately one in three queries (31.1%; 185/594) was submitted by internists. 82.8% (492/594) of the queries were patient-specific, while the remaining 17.2% (102/594) were general queries. Adverse drug reactions (ADRs), indications/contraindications, and pharmacodynamic interactions (PDIs) represented the three most frequently addressed query categories, being involved in 44.8% (266/594), 43.3% (257/594), and 34.3% (204/594) of all queries, respectively (assignment of more than one category per query was possible). As compared to general queries, patient-specific queries were statistically significantly more often related to ADRs, PDIs, and pharmacokinetic interactions (PKIs) (ADRs: 35.3% vs. 46.7%, P = 0.034; PDIs: 14.7% vs. 38.4%, P < 0.001; PKIs: 20.6% vs. 31.5%, P = 0.028). To demonstrate the complexity of queries submitted to the clinical-pharmacological DIC, we present and comment on an illustrative selection of queries.

Medicines information services in a resource-limited setting

INTRODUCTION

In resource-limited settings, it is particularly important to explore the priorities for, as well as barriers to, development of health services. There has been limited development of medicines information (MI) services in Vietnam despite national guidelines.

OBJECTIVES

To explore the current status of MI services for healthcare professionals and patients in Vietnamese hospitals.

METHODS

In 2018, all hospitals which were under the direct administration of the Ministry of Health and all 63 Provincial Health Bureaus were invited to participate (n = 1359). All national, provincial and district hospitals, as well as private hospitals and hospitals from other Ministries in Vietnam, were included. An online questionnaire about MI facilities, workforce, and activities was used.

RESULTS

There were 560 eligible responses from pharmacists in hospitals. The most common MI service was pharmacovigilance (provided in 91% of hospitals), and the least common was providing MI for clinical case management (30%), nurse training (31%), and MI provision to patients (27%). Multivariate logistic regression analysis showed that the number of pharmacists and the geographical-economical area where hospitals were based had the strongest impact on the likelihood of offering more MI services in hospitals. While the type of hospital (traditional medicine vs. other hospitals) had some impact, hospital size, level, and specialization of hospital (general vs. specialized) did not have a significant impact on the provision of MI services.

CONCLUSION

The differences in workforce and location may contribute to differences in MI practices between hospitals. These findings are relevant for the implementation of a national MI strategy in Vietnam and other developing countries.

A systematic review examining the effectiveness of medicines information services for patients and the general public

OBJECTIVES

Hospital-based patient medicines helpline services (PMHS) and medicines information services for the general public (MISGP) are available in many countries to support people with their medicines. Our aim was to examine the available evidence regarding the effectiveness of PMHS and MISGP.

METHODS

Searches were conducted using Medline, EMBASE, CINAHL, Scopus and Web of Science, on 11 August 2018. Forward and backward citation searches were conducted, grey literature was searched, and study quality/risk of bias was assessed. Findings were synthesised in a narrative synthesis. Where appropriate, weighted means were calculated.

KEY FINDINGS

Thirty-two studies were identified for inclusion (17 published articles, 15 conference abstracts). Eighteen studies were conducted within the United Kingdom. Mean quality assessment was moderate (51%), and risk of bias was high (63%). PMHS and MISGP are both typically perceived as positive (e.g. 94% and 91% of participants were satisfied with using a PMHS and MISGP, respectively). For PMHS, the advice received is reported to be usually followed (94%, and 66% for MISGP). For both services, users report several positive outcomes (e.g. problems resolved/avoided, feeling reassured and improved health). PMHS may also be effective for correcting medicines-related errors (up to 39% of calls may concern such errors) and for potentially avoiding medicines-related harm (48% of enquiries concerned situations that were judged to have the potential to harm patients).

CONCLUSIONS

Findings suggest that both PMHS and MISGP may be beneficial sources of medicines-related support. However, the moderate quality and high risk of bias of studies highlight that more high-quality research is needed.

Use of References in Responses from Scandinavian Drug Information Centres

Background: The aim of this study was to compare use of references in responses from Scandinavian drug information centres (DICs). Methods: Six different fictitious drug-related queries were sent to each of seven Scandinavian DICs. The six queries concerned adverse effects, pharmacokinetics, pregnancy, complementary medicine, polypharmacy, and breast feeding. References in the responses were categorised into five types of drug information sources: primary (original studies), secondary (reviews), tertiary (drug monographs, handbooks, etc.), DIC database, or personal communication. Results: Two hundred and forty-four references were used in the 42 responses. The mean number of references varied from 3.0 to 10.6 for the six queries. The largest difference between centres with regard to number of references used (range 1⁻17) was found for the query on complementary medicine. In total, 124 references (50.8%) were tertiary, and only 10 of the 42 responses (23.8%) did not have any tertiary references included. Complementary medicine, breast feeding, and pregnancy were query types associated with relatively frequent use of primary references. Use of DIC database was not uncommon, but personal communications were seldom used. Conclusions: Scandinavian DICs differ substantially in number and type of references to identical drug-related queries. Tertiary sources are mainly preferred irrespective of type of query.

A survey of UK dental health professionals using a medicines information service: what questions do they ask and do they get useful answers?

Dentists prescribe a limited range of medicines but it is important that they consider the effects of all medicines their patients are taking when providing dental care. In the UK, a national medicines information (UKMi) service funded by the National Health Service is available to advise health professionals on prescribing and to support evidence-based practice. This paper presents the results of a survey of 151 dental health professionals who contacted the UKMi service for advice. Enquiries most commonly involved antibiotics (32%), but dental health professionals also asked for advice on legal issues relating to medicines (10%), and on managing patients receiving bisphosphonates (9%), local anaesthetics (6%) and antiplatelet drugs (5%). One hundred and forty-six (97%) enquirers used the advice provided: for managing current patients, planning the care of future patients, for continuing professional development and teaching others. Two thirds of enquirers used the information provided to check if current or proposed management was appropriate, one half to change therapy and over one quarter to identify, manage or avoid adverse effects or drug interactions.

Utility and value of a medicines information service provided by pharmacists: a survey of health professionals

OBJECTIVES

many health professionals lack the time and skills to search for and appraise information on medicines. A solution might be to use others skilled in evidence appraisal, who make recommendations or provide information tailored to patients' needs. The objectives of this study were to assess how advice provided to health professionals by the northwest of England regional medicines information centre is used, whether it is useful for patient care and to measure satisfaction with the service.

METHODS

a questionnaire was designed and sent to health professionals who contacted the centre between September 2008 and March 2009. Enquirers contacting the centre more than once were sent a questionnaire only in response to their first enquiry during the study period. Non-responders were sent a reminder.

KEY FINDINGS

questionnaires were sent to 672 enquirers; 68% were returned. Nearly all respondents used the advice provided. Of the 430 respondents who provided data on how they used the information, 81% used it to manage a current patient and 29% to plan the care of future patients; nearly all considered it useful. Where data were given (n = 366), half used it to check if current or proposed management was appropriate, 45% to make changes to therapy and 35% to advise another health professional. In addition to patient care, one-quarter (n = 105/430) of respondents used the information for continuing professional development and 16% (n = 69/430) for training or teaching.

CONCLUSIONS

health professionals value the enquiry-answering service and use the advice provided for patient care, continuing professional development and educating patients and other health professionals. The service is responsive, supporting the care of patients needing immediate and future management.

Evaluation of tools to prevent drug incompatibilities in paediatric and neonatal intensive care units

OBJECTIVE

Intravenous drug administration in neonatal (NICU) and paediatric intensive care units (PICU) is critical because of poor venous access, polymedication, fluid restriction and low infusion rate. Risk is further increased by inadequate information on the physicochemical compatibility of drugs. Eight decision-supporting tools were hence evaluated to improve the detection of drug incompatibilities in paediatric wards.

SETTING

NICU and PICU, University hospital.

METHOD

Eight tools (Thériaque 2007, Stabilis 3, Perfysi 2 databases; KIK 3.0 software; Neofax 2007 handbook; King 2008 Guide, CHUV 9.0, pH 2007 cross-tables) were assessed by two pharmacists using 40 drug pairs (20 incompatible; 20 compatible) frequently prescribed in PICUs and NICUs. Trissel's 14th Ed. handbook served as the gold standard. Four criteria were evaluated (each with a maximum of 250 points): accuracy (sensitivity, specificity, positive and negative predictive values), completeness (number of drug pairs documented), comprehensiveness (presence of 16 different items), and applicability (by combining the time needed by 7 pharmacists to classify 5 drug pairs, plus an evaluation of their design, usefulness, reliability and ergonomics, using visual analogy scales). The percentage of non-compliant answers (NCA) was calculated for both the performing pharmacists and the tools.

MAIN OUTCOME MEASURE

Global score of drug incompatibilities (accuracy + completeness + comprehensiveness + applicability).

RESULTS

Thériaque obtained the best global score (840/1000 points), followed by pH (807), CHUV (803), Perfysi (776), Neofax (678), King Guide (642), Stabilis (584) and KIK (523), respectively. The highest scores were reached by Thériaque for accuracy (234/250); Thériaque and pH for completeness (200/250); Thériaque and Perfysi for comprehensiveness (218/250); and pH for applicability (298/250). The range of pharmacists' NCAs was between 9% (4/45 NCAs) and 33% (15/45), whereas that for drug pairs was between 10% (6/63) and 30% (19/63). The range of NCAs for tools was between 6% (2/35, pH) and 49% (18/35, Perfysi).

CONCLUSIONS

Thériaque proved outstanding as a drug-incompatibility tool. However, all resources showed some shortcomings. The large ranges of pharmacists' NCAs shows that such an assessment is subject to different interpretations. Standard operating procedures for drug-incompatibility assessment should be implemented in drug-information centres. Tools with low NCA percentage, such as the pH or CHUV tables, may be useful for nurses in ICUs.

Scope of international hospital pharmacy practice

OBJECTIVE

To review the published English literature regarding international hospital pharmacy practice.

DATA SOURCES

A computer search of all English-language articles in MEDLINE (1966-June 2004) and other Internet sources and International Pharmaceutical Abstracts (1971-June 2004).

STUDY SELECTION AND DATA EXTRACTION

All studies that discussed hospital pharmacy or clinical hospital pharmacy activities outside of the US were considered for inclusion.

DATA SYNTHESIS

The scope of international hospital pharmacy practice is quite varied, both inter- and intra-country, and varying degrees of specialization exist. Although clinical pharmacy is well developed in some countries, it is still in infancy stages in others. In addition, there is disparity in the actual definition of clinical pharmacy throughout the world.

CONCLUSIONS

Since very few data have been published regarding hospital pharmacy practice on an international scale, we suggest a survey be conducted to objectively capture this information and increase awareness of clinical pharmacy in this setting.
