Risk minimisation measures (RMM) are put in place to ensure safe and effective use of medicines. This study assessed whether RMM for five medicines are implemented in Dutch clinical guidelines.
Descriptive study.
Dutch clinical guidelines where treatment with valproate, fluoroquinolones, methotrexate, metformin or fluorouracil was recommended were identified. In those guidelines that had been updated after publication of the RMM, we determined whether RMM-information was included in the guideline.
Out of 50 identified guidelines recommending treatment with one of the five medicines, only 21 (42%) were revised after RMM-implementation. Of these 21 guidelines, 12 (n = 57%) included RMM-related information.
Uptake of RMM information in Dutch clinical guidelines is limited and RMM-publication does not prompt guideline updates. This suggests that guidelines alone are not an optimal way to inform health care professionals of new safety warnings.

UNASSIGNED: Clozapine is the only antipsychotic approved for treatment-resistant schizophrenia, but without appropriate monitoring, it can be associated with potentially fatal outcomes. An International Adult Clozapine Titration Guideline categorizes patients into normal or slow metabolizers. Categorization provides clozapine titration schedules and recommends regular c-reactive protein (CRP) and clozapine concentration monitoring to reduce the risk of adverse drug reactions (ADRs). The impact of the guideline on clozapine ADRs has not been evaluated.
UNASSIGNED: A retrospective chart review assessed clozapine titrations, laboratory monitoring, ADRs, and discontinuations for clozapine-naive adult inpatients at a single center from January 1, 2013, to June 1, 2022. Each patient\'s cumulative weekly clozapine dosage was compared with their guideline recommended dosage to create a percent accordance. Linear logistic regression evaluated the relationship between titration speed and the presence of an ADR, while descriptive statistics analyzed laboratory monitoring.
UNASSIGNED: Forty-three patients were included, with the majority being White males with schizophrenia. An inverse relationship existed between the last inpatient week clozapine dose percent accordance and the probability of an ADR. Nonobese patients were less likely than obese patients to experience an ADR (odds ratio = 0.17; 95% CI, 0.03-0.99). CRP and clozapine concentration monitoring was suboptimal.
UNASSIGNED: Based on our small retrospective review of primarily White males, more aggressive clozapine titrations did not increase ADRs. Future studies with more diverse samples are needed and should focus on specific ADRs, which may have increased occurrence with rapid titrations. Obese patients were at higher risk of ADRs, correlating with the guideline-recommended slower titrations for these patients.

BACKGROUND: The SAVVY project aims to improve the analyses of adverse events (AEs) in clinical trials through the use of survival techniques appropriately dealing with varying follow-up times and competing events (CEs). This paper summarizes key features and conclusions from the various SAVVY papers.
METHODS: Summarizing several papers reporting theoretical investigations using simulations and an empirical study including randomized clinical trials from several sponsor organizations, biases from ignoring varying follow-up times or CEs are investigated. The bias of commonly used estimators of the absolute (incidence proportion and one minus Kaplan-Meier) and relative (risk and hazard ratio) AE risk is quantified. Furthermore, we provide a cursory assessment of how pertinent guidelines for the analysis of safety data deal with the features of varying follow-up time and CEs.
RESULTS: SAVVY finds that for both, avoiding bias and categorization of evidence with respect to treatment effect on AE risk into categories, the choice of the estimator is key and more important than features of the underlying data such as percentage of censoring, CEs, amount of follow-up, or value of the gold-standard.
CONCLUSIONS: The choice of the estimator of the cumulative AE probability and the definition of CEs are crucial. Whenever varying follow-up times and/or CEs are present in the assessment of AEs, SAVVY recommends using the Aalen-Johansen estimator (AJE) with an appropriate definition of CEs to quantify AE risk. There is an urgent need to improve pertinent clinical trial reporting guidelines for reporting AEs so that incidence proportions or one minus Kaplan-Meier estimators are finally replaced by the AJE with appropriate definition of CEs.

Immune checkpoint inhibitors (ICIs) have emerged as crucial therapeutic agents for various malignancies by activating the host immune system against tumor cells. However, many different types of skin adverse reactions may occur during its use, including eruption, pruritus, blistering, hypopigmentation, alopecia, and even severe cases, Stevens-Johnson syndrome (SJS)/toxic epidermal necrolysis (TEN). These cutaneous immune-related adverse events (cirAEs) had a high incidence, which seriously affected patients\' quality of life and antitumor treatment decisions. Some severe cutaneous adverse reactions (SCARs) even endanger patients\' lives. Therefore, the Chinese Society of Dermatology, the Chinese Dermatologist Association of the Chinese Medical Doctor Association, the Dermatology Division of the Chinese Geriatrics Society, and other relevant experts jointly discussed and formulated the \'Chinese Expert Consensus on the Diagnosis and Treatment of Immune Checkpoint Inhibitor-Related Cutaneous Adverse Reactions\'. This consensus covers the name, epidemiology, pathogenesis, clinical features, classification and grading of cirAEs, principles of management and the re-initiation of ICIs. It aims to provide a more scientific and authoritative reference for the diagnosis and treatment of cirAEs in China in the future.
免疫检查点抑制剂（ICIs）通过激活机体免疫系统抵御肿瘤细胞，目前已成为多种恶性肿瘤的重要治疗手段。但其使用过程中可能发生多种不同类型的皮肤不良反应，包括斑丘疹、瘙痒、水疱病变、色素减退和脱发等，严重者出现类似Steven-Johnson综合征/中毒性表皮坏死松解症（SJS/TEN）样表现。这些ICIs相关皮肤相关不良反应（cirAEs）发生率高，严重影响患者的生活质量和医师的治疗决策，部分严重的皮肤不良反应（SCARs）甚至危及生命。为此，中华医学会皮肤性病学分会、中国医师协会皮肤科医师分会、中国老年医学学会皮肤医学分会和其他相关领域的专家共同讨论并制订了《免疫检查点抑制剂相关皮肤不良反应诊治中国专家共识（2024版）》。此共识包括cirAEs的命名与流行病学、发病机制、临床特征、分类分级、诊断依据、治疗策略与ICIs的重启治疗等，旨在为中国cirAEs的诊治提供更科学、更权威的参考依据。.

BACKGROUND: Falls are a significant public health problem and constitute a major cause of injuries and mortality. Risk factors for falls are multifactorial and include medication use.
OBJECTIVE: To develop and investigate the content validity of the Medication-Related fall (MRF) screening and scoring tool.
METHODS: The MRF tool was developed from clinical practice guidelines addressing medication-related problems, and additional medications identified by specialist pharmacists across a region of the United Kingdom (Northern Ireland). Medication classes were categorised according to their \'potential to cause falls\' as: high-risk (three points), moderate-risk (two points) or low-risk (one point). The overall medication-related falls risk for the patient was determined by summing the scores for all medications. The MRF was validated using Delphi consensus methodology, whereby three iterative rounds of surveys were conducted using SurveyMonkey®. Twenty-two experts from 10 countries determined their agreement with the falls risk associated with each medication on a 5-point Likert scale. Only medications with at least 75% of respondents agreeing or strongly agreeing were retained in the next round.
RESULTS: Consensus was reached for 19 medications/medication classes to be included in the final version of the MRF tool; ten were classified as high-risk, eight as moderate-risk and one as low-risk.
CONCLUSIONS: The MRF tool is simple and has the potential to be integrated into medicines optimisation to reduce falls risk and negative fall-related outcomes. The score from the MRF tool can be used as a clinical parameter to assess the need for medication review and clinical interventions.

OBJECTIVE: Mitotane is an important cornerstone in the treatment of pediatric adrenal cortical tumors (pACC), but experience with the drug in the pediatric age group is still limited and current practice is not guided by robust evidence. Therefore, we have compiled international consensus statements from pACC experts on mitotane indications, therapy, and management of adverse effects.
METHODS: A Delphi method with 3 rounds of questionnaires within the pACC expert consortium of the international network groups European Network for the Study of Adrenal Tumors pediatric working group (ENSAT-PACT) and International Consortium of pediatric adrenocortical tumors (ICPACT) was used to create 21 final consensus statements.
RESULTS: We divided the statements into 4 groups: environment, indications, therapy, and adverse effects. We reached a clear consensus for mitotane treatment for advanced pACC with stages III and IV and with incomplete resection/tumor spillage. For stage II patients, mitotane is not generally indicated. The timing of initiating mitotane therapy depends on the clinical condition of the patient and the setting of the planned therapy. We recommend a starting dose of 50 mg/kg/d (1500 mg/m²/d) which can be increased up to 4000 mg/m2/d. Blood levels should range between 14 and 20 mg/L. Duration of mitotane treatment depends on the clinical risk profile and tolerability. Mitotane treatment causes adrenal insufficiency in virtually all patients requiring glucocorticoid replacement shortly after beginning. As the spectrum of adverse effects of mitotane is wide-ranging and can be life-threatening, frequent clinical and neurological examinations (every 2-4 weeks), along with evaluation and assessment of laboratory values, are required.
CONCLUSIONS: The Delphi method enabled us to propose an expert consensus statement, which may guide clinicians, further adapted by local norms and the individual patient setting. In order to generate evidence, well-constructed studies should be the focus of future efforts.

UNASSIGNED: Irrational prescribing practices have major consequences on patient safety and also increase the economic burden. Real-life examples of impact of irrational prescription have potential to improve prescribing practices. In this context, the present study aimed to capture and evaluate the prevalence of deviations from treatment guidelines in the prescriptions, potential consequence/s of the deviations and corrective actions recommended by clinicians.
METHODS: It was a cross-sectional observational study conducted in the outpatient departments of tertiary care hospitals in India wherein the 13 Indian Council of Medical Research Rational Use of Medicines Centres are located. Prescriptions not compliant with the standard treatment guidelines and incomplete prescriptions with respect to formulation, dose, duration and frequency were labelled as \'prescriptions having deviations\'. A deviation that could result in a drug interaction, lack of response, increased cost, preventable adverse drug reaction (ADR) and/or antimicrobial resistance was labelled as an \'unacceptable deviation\'.
RESULTS: Against all the prescriptions assessed, about one tenth of them (475/4838; 9.8%) had unacceptable deviations. However, in 2667/4838 (55.1%) prescriptions, the clinicians had adhered to the treatment guidelines. Two thousand one hundred and seventy-one prescriptions had deviations, of which 475 (21.9%) had unacceptable deviations with pantoprazole (n=54), rabeprazole+domperidone (n=35) and oral enzyme preparations (n=24) as the most frequently prescribed drugs and upper respiratory tract infection (URTI) and hypertension as most common diseases with unacceptable deviations. The potential consequences of deviations were increase in cost (n=301), ADRs (n=254), drug interactions (n=81), lack of therapeutic response (n=77) and antimicrobial resistance (n=72). Major corrective actions proposed for consideration were issuance of an administrative order (n=196) and conducting online training programme (n=108).
UNASSIGNED: The overall prevalence of deviations found was 45 per cent of which unacceptable deviations was estimated to be 9.8 per cent. To minimize the deviations, clinicians recommended online training on rational prescribing and administrative directives as potential interventions.

There are currently no universally accepted guidelines for the management of digoxin toxicity. In the absence of clinical practice guidelines, a set of consensus recommendations for management of digoxin toxicity in the clinical setting were developed through a modified Delphi approach. The recommendations highlight the importance of early recognition of signs of potentially life-threatening toxicity that requires immediate treatment with digoxin-specific antibodies. The consensus identifies a straightforward approach to dosing immune antibody fragments according to the presence or absence of signs of life-threatening toxicity. Supportive measures and management of specific signs of toxicity are also covered.
