Evaluation of patients treated for diabetic retinopathy: an analysis of the administrative databases of the Lazio Region

BACKGROUND: In Italy there are an estimated 4 million patients suffering from diabetes mellitus (DM). The most important ocular complication of DM is diabetic retinopathy (DR), which affects about one third of diabetic patients.AIMS: To identify, within the Lazio Region, the cohort of patients starting treatment for DME in the years 2010-2016 and calculating the annual cost of therapy; and to assess the appropriateness of the drugs prescribed.METHODS: From the Health Information System of the Lazio Region were identified all subjects who, in the 2010-2016 period, had received at least one prescription for dexamethasone intravitreal implant (i.i.) or intravitreal triamcinolone or ranibizumab or aflibercept or bevacizumab. For the cohort of users selected, the appropriateness of the treatment were evaluated calculating the number of administrations performed in the first four months of the index prescription and the number of administrations performed during the 12 months of treatment.RESULTS: In 2016, 7,265 patients in the Lazio Region received at least one prescription of ranibizumab (43.0%), aflibercept (37.5%) and dexamethasone i.i. (19.5%). Among the 3,416 patients naïve at 6 months, who started treatment in the 2013-2015 period and who did not switch to different drugs, 78.7% started treatment with ranibizumab, 16.0% with dexamethasone i.i. and 5.3% with aflibercept. The mean annual cost for the treatment of a patient with DME and naïve at 6 months was equal to € 2,388; a total cost for only the naïve patients selected in the 2013-2015 period is therefore estimated at approximately € 8.2 million. The average annual cost of dexamethasone i.i. treatment was € 1,497, lower than that of ranibizumab (€ 2,562) and aflibercept (€ 2,485). The expenditure for patients receiving less than 3 administrations of ranibizumab or aflibercept in the first 10 months of treatment was estimate equal to € 1.3 million.CONCLUSIONS: The administrations of dexamethasone i.i. are in line with what is indicated in the prescribing information, while for ranibizumab and aflibercept a potential under-use has been identified. A greater appropriateness of the drugs prescribed, accompanied by an optimal adherence to therapy, would strongly reduce the current waste of resources

Impact of new DAA therapy on real clinical practice: a multicenter region-wide cohort study

Abstract Background Management of chronic hepatitis C (CHC) has significantly accelerated in the last few years. Currently, second generation direct acting antivirals (DAAs) promise clearance of infection in most of patients. Here we present the results of the first analysis carried out on data of Lazio clinical network for DAAs. Methods The study was designed as a multicenter cohort: a) to assess the evolution of treatment during the first 24 months of the activity of the Clinical Network; b) to report overall efficacy of treatments; c) to analyze potential factors associated with lack of virological response at 12 weeks after therapy (SVR12); d) to evaluate the variation of ALT at baseline and 12 weeks after therapy in those who achieved SVR12 in comparison to those who did not. Analyses of efficacy were carried out with multilevel mixed effect logistic regression model. ALT temporal variation was assessed by mixed effect model mixed models with random intercept at patient’s level and random slope at the level of the time; i.e. either before or after therapy. Results Between 30 December 2014 and 31 December 2016 5279 patients started a DAA treatment; of those, 5127 (in 14 clinical centers) had completed the 12-week follow-up. Overall proportion of SVR12 was 93.41% (N = 4780) with no heterogeneity between the 14 clinical centers. Interruption as the consequence of severe side effect was very low (only 23 patients). Unadjusted analysis indicates that proportion of SVR12 significantly changes according to patient’s baseline characteristics, however after adjusting for potential confounders only adherence to current guidelines, stage of liver diseases, gender, transplant and HIV status were independently associated with the response to therapy. Analysis of ALT temporal variation showed that ALT level normalized in most, but not, all patients who achieved SVR12. Conclusion Our study confirmed the extraordinary efficacy of DAAs outside clinical trials. The advantage of DAAs was particularly significant for those patients who were previously considered as difficult-to-treat and did not have treatment options before DAAs era. Intervention based on network of select centers and prioritization of patients according to diseases severity was successful. Further studies are needed to establish whether clearance of HCV after DAAs therapy can arrest or even revert liver fibrosis in non-cirrhotic patients and/or improve life quality and expectancy in those who achieve SVR12 with cirrhosis
