La produzione di raccomandazioni cliniche con il metodo GRADE: l'esperienza sui farmaci oncologici

Questo Dossier \ue8 dedicato alla presentazione del background scientifico e dei risultati del Progetto AFO (Appropriatezza farmaci oncologici) sviluppato dall\u2019Agenzia sanitaria e sociale della Regione Emilia-Romagna nell\u2019ambito del Programma Ricerca e innovazione (PRI E-R). Dal punto di vista del background scientifico l\u2019elemento di originalit\ue0 del progetto \ue8 stato la sperimentazione dell\u2019uso del metodo GRADE (Grading of Recommendations Assessment, Development and Evaluation) per la produzione e graduazione di raccomandazioni cliniche relative all\u2019effetto degli interventi sanitari. Il metodo GRADE \ue8 nato dall\u2019attivit\ue0 avviata nel 2000 di un gruppo di lavoro internazionale che ha ritenuto necessario mettere a punto un approccio unificato alla produzione di raccomandazioni cliniche in presenza di una molteplicit\ue0 di sistemi di grading tra loro non sempre coerenti e la cui variabilit\ue0 mette in serio pericolo la fruibilit\ue0 dello strumento linee guida/raccomandazioni. Dal punto di vista dei contenuti e delle modalit\ue0 operative, il Progetto AFO - che ha anche ottenuto un finanziamento da parte del Ministero del Lavoro, della salute e delle politiche sociali nell\u2019ambito del Programma Ricerca finalizzata (Fondo ex art. 12 DLgs 502/1992) - \ue8 nato con l\u2019obiettivo di sperimentare la possibilit\ue0 di coinvolgere gruppi multidisciplinari di clinici nella produzione di raccomandazioni sull\u2019uso appropriato di farmaci oncologici, sia nuovi sia gi\ue0 registrati ma in evoluzione per quanto riguarda le indicazioni cliniche. Nella prima parte del Dossier, dopo una breve introduzione relativa alla filosofia del programma PRI E-R e agli scopi del progetto AFO, viene presentato il metodo GRADE, le sue assunzioni e le tappe operative di applicazione. Nella seconda parte vengono presentati i risultati del lavoro dei tre panel multisciplinari che hanno prodotto complessivamente 32 raccomandazioni per la terapia adiuvante e la fase avanzata del trattamento dei tumori della mammella, del colon retto e del polmone. Conclude la seconda parte del Dossier una discussione circa le criticit\ue0 di applicazione del metodo e le potenzialit\ue0 e i limiti del suo utilizzo per la produzione di strumenti utili al miglioramento dell\u2019appropriatezza d\u2019uso dei farmaci. Nell\u2019Appendice viene infine riportato, a scopo esemplificativo, il testo di due raccomandazioni relative all\u2019uso del trastuzumab nella terapia adiuvante del tumore della mammella e delle fluoropirimidine nella terapia adiuvante del tumore del colon.This report is devoted to the presentation of the scientific background and results of the AFO (an acronym standing for Appropriateness of Oncologic Drugs) project developed by the Health Care and Social Agency of Emilia-Romagna region in the framework of the Research and Innovation program (PRI E-R). From the methodological standpoint the novelty of the project stems from the utilisation of the GRADE method (Grading of Recommendation, Assessment, Development and Evaluation) for the production and grading of clinical recommendations on the effects of health care interventions. The GRADE method originated from the work of an international working group that, starting 2001, was convened to go beyond the variations in the existing methods for producing and grading clinical recommendations. These variations were mostly due to conceptual inconsistencies that, if not properly recognised and addressed, would jeopardise the credibility of the entire guidelines movement. From the subject matter standpoint the AFO project - which was also partially supported by a research grant from the Italian Ministry of Welfare, Health and Social Affairs - was conceived to test the feasibility of a working methodology where multidisciplinary panels of clinicians would be convened to produce clinical recommendations on newly registered drugs as well as those already in widespread use but whose indications change over time. In the first part of the report, after a brief introduction on the working hypotheses and objectives of the PRI ER program and the AFO project, the GRADE method is presented and discussed. In the second part the results of the activities of the three panels that produced a total of 32 recommendations for the adjuvant and advanced treatment of breast, colorectal and lung cancer are reported. The final session of the report addresses some open issues relative to the application of the GRADE method to the production of clinical recommendations construed with the explicit aim of improving quality and appropriateness of care in oncology. In the Appendix, two examples of the recommendations produced though this project are presented: they refer to Trastuzumab in the treatment of early breast cancer and Fluoropirimide in the adjuvant therapy of colon cancer

Family doctors' knowledge and self-reported care of type 2 diabetes patients in comparison to the clinical practice guideline: cross-sectional study

BACKGROUND: It is widely believed that providing doctors with guidelines will lead to more effective clinical practice and better patient care. However, different studies have shown contradictory results in quality improvement as a result of guideline implementation. The aim of this study was to compare family doctors' knowledge and self-reported care of type 2 diabetes patients with recommendation standards of the clinical practice guideline. METHODS: In April 2003 a survey was conducted among family doctors in Estonia. The structured questionnaire focused on the knowledge and self-reported behavior of doctors regarding the guideline of type 2 diabetes. The demographic and professional data of the respondents was also provided. RESULTS: Of the 354 questionnaires distributed, 163 were returned for a response rate of 46%. Seventy-six percent of the responded doctors stated that they had a copy of the guideline available while 24% reported that they did not. Eighty-three percent of the doctors considered it applicable and 79% reported using it in daily practice. The doctors tended to start treatment with medications and were satisfied with treatment outcomes at higher fasting blood glucose levels than the levels recommended in the guideline. Doctors' self-reported performance of the tests and examinations named in the guideline, which should be performed within a certain time limit, varied from overuse to underuse. Blood pressure, serum creatinine, eye examination and checking patients' ability to manage their diabetes were the best-followed items while glycosylated hemoglobin and weight reduction were the most poorly followed. Doctors' behavior was not related to the fact of whether they had the guideline available, whether they considered it applicable, or whether they actually used it. CONCLUSION: Doctors' knowledge and self-reported behavior in patient follow-up of type 2 diabetes is very variable and is not related to the reported availability or usage of the guideline. Practice guidelines may be a useful source of information but they should not be overestimated

20-Year Risks of Breast-Cancer Recurrence after Stopping Endocrine Therapy at 5 Years

The administration of endocrine therapy for 5 years substantially reduces recurrence rates during and after treatment in women with early-stage, estrogen-receptor (ER)-positive breast cancer. Extending such therapy beyond 5 years offers further protection but has additional side effects. Obtaining data on the absolute risk of subsequent distant recurrence if therapy stops at 5 years could help determine whether to extend treatment

Long-term outcomes for neoadjuvant versus adjuvant chemotherapy in early breast cancer: meta-analysis of individual patient data from ten randomised trials

Background Neoadjuvant chemotherapy (NACT) for early breast cancer can make breast-conserving surgery more feasible and might be more likely to eradicate micrometastatic disease than might the same chemotherapy given after surgery. We investigated the long-term benefits and risks of NACT and the influence of tumour characteristics on outcome with a collaborative meta-analysis of individual patient data from relevant randomised trials. Methods We obtained information about prerandomisation tumour characteristics, clinical tumour response, surgery, recurrence, and mortality for 4756 women in ten randomised trials in early breast cancer that began before 2005 and compared NACT with the same chemotherapy given postoperatively. Primary outcomes were tumour response, extent of local therapy, local and distant recurrence, breast cancer death, and overall mortality. Analyses by intention-to-treat used standard regression (for response and frequency of breast-conserving therapy) and log-rank methods (for recurrence and mortality). Findings Patients entered the trials from 1983 to 2002 and median follow-up was 9 years (IQR 5–14), with the last follow-up in 2013. Most chemotherapy was anthracycline based (3838 [81%] of 4756 women). More than two thirds (1349 [69%] of 1947) of women allocated NACT had a complete or partial clinical response. Patients allocated NACT had an increased frequency of breast-conserving therapy (1504 [65%] of 2320 treated with NACT vs 1135 [49%] of 2318 treated with adjuvant chemotherapy). NACT was associated with more frequent local recurrence than was adjuvant chemotherapy: the 15 year local recurrence was 21·4% for NACT versus 15·9% for adjuvant chemotherapy (5·5% increase [95% CI 2·4–8·6]; rate ratio 1·37 [95% CI 1·17–1·61]; p=0·0001). No significant difference between NACT and adjuvant chemotherapy was noted for distant recurrence (15 year risk 38·2% for NACT vs 38·0% for adjuvant chemotherapy; rate ratio 1·02 [95% CI 0·92–1·14]; p=0·66), breast cancer mortality (34·4% vs 33·7%; 1·06 [0·95–1·18]; p=0·31), or death from any cause (40·9% vs 41·2%; 1·04 [0·94–1·15]; p=0·45). Interpretation Tumours downsized by NACT might have higher local recurrence after breast-conserving therapy than might tumours of the same dimensions in women who have not received NACT. Strategies to mitigate the increased local recurrence after breast-conserving therapy in tumours downsized by NACT should be considered—eg, careful tumour localisation, detailed pathological assessment, and appropriate radiotherapy

A comparison of EuroQol 5-Dimension health-related utilities using Italian, UK, and US preference weights in a patient sample

Weights have not been calculated for every country; however, empirical research shows that cross-country differences exist. This empirical study aims at investigating the impact of recently developed Italian weights in comparison with UK and US scores on health-related utility calculation using a sample of patients with Crohn's disease. The study is based on a survey on health-related quality of life in patients (n=552) affected by active Crohn's disease conducted in Italy from 2012 to 2013. Utilities computed through the Italian algorithm (mean: 0.76; SD: 0.20; median: 0.81) are generally higher than US (mean: 0.69; SD: 0.22; median: 0.77) and UK (mean: 0.57; SD: 0.32; median: 0.69) utilities, except for extremely severe health states where US values outweigh the Italian ones. UK preference weights generate the highest number of negative results. All the three value distributions are left-skewed due to very low scores associated with the most serious health states (ie, three or four levels equal to 3). As expected, despite the tariff set considered, more severe disease (Harvey Bradshaw Index >16) reduces the mean conditional EQ-5D-3L index (P<0.0001). Kendall's rank correlation between EQ Visual Analog Scale score and EQ-5D-3L index is positive (P<0.0001), even though patients tend to value their health-related quality of life more when responding to EQ-5D-3L questions than on EQ Visual Analog Scale. Regardless of the tariff set considered, ordinary least-square results highlight that more severe disease (Harvey Bradshaw Index >16) reduces the mean conditional EQ-5D-3L index (P<0.0001). Results reveal remarkable differences among the three national tariff sets and especially when severe health states occur, suggesting the need for country-specific preference weights when evaluating utilities, which can be problematic since they have not been calculated for every country yet. Keywords: EQ-5D, preference weights, utility values, VAS, Crohn's diseas

The impact of a pharmacist as a member of healthcare team on facilitating evidenced-based prescribing of innovative drugs in an Italian oncology department

AIMS AND BACKGROUND: At the Oncology Department of the Chieti and Ortona Hospitals, the pharmacist designated by the Abruzzo Region to oversee the obligatory monitoring of innovative oncological drugs listed in the database of the Italian Medicines Agency (AIFA) collaborates with oncologists to educate them about evidenced-based prescribing for off-label uses of drugs and to optimize the efficiency of spontaneous reporting of adverse drug reaction (ADR) local system. METHODS: The contribution of the pharmacist as a member of the healthcare team was evaluated using the following indices: the percentage of off-label prescriptions of the innovative drugs monitored, the number of reported ADRs, and the percentage of pharmacist suggestions actually implemented by physicians. RESULTS: In the course of 3 years (2008-2010), the pharmacist monitored a total of 843 patients treated with 716 appropriate uses and 127 off-label uses of drugs, oversaw a reduction in the latter from 28.3% in 2008 to 9.6% in 2010, and contributed to almost tripling the number of reported ADRs, from 10 in 2008 to 27 in 2010. In 2010, the pharmacist identified 60 potentially inappropriate prescribing cases, and proposed more appropriate prescriptions for each case: 68.3% (41) of the suggestions were implemented by the physicians and only 31.7% (19) were not. According to answers to a questionnaire administered at the end of the 2010 to evaluate the usefulness of this particular collaboration, physicians are interested in continuous and extensive collaboration. CONCLUSIONS: This article demonstrates that a pharmacist, active in the department as part of the heath-care team, can facilitate evidenced-based prescribing for off-label uses of drugs and improve spontaneous reporting of ADRs

Gemcitabine-induced posterior reversible encephalopathy syndrome: a case report.

Gemcitabine is a commonly used chemotherapeutic agent for a variety of tumors. Although this nucleoside analog antineoplastic agent is similar in structure to cytarabine, central nervous system toxicities have rarely been attributed to gemcitabine. The posterior reversible encephalopathy syndrome (PRES) is a condition characterized by reversible neurological and radiological findings that has been associated with use of chemotherapeutic and more recently novel targeted therapies. We describe one case of a 41-year-old woman with PRES under treatment for leiomyosarcoma because of the probable association with gemcitabine. Our case, to our knowledge, represents the seventh published report of this particular toxicity. Naranjo algorithm, efficacious method for assessing the causality of adverse drug reactions (ADRs) from a case report, suggests a direct casual relationship. PRES is probably a rare complication of gemcitabine, but the oncologist should take it into careful consideration, because PRES is reversible with treatment of current hypertension or removal of the causative agent. However, failure to quickly recognize the syndrome and discontinue the offending agent may result in profound and permanent central nervous system dysfunction or death
