Electronic Prescribing tools (e-prescribing) have shown several benefits in terms of prescribing process adequacy and health care quality in hospital settings. We hypothesize however, that an undesired effect of digitalisation, due to the easier and faster prescribing process allowing patients to skip face-to-face conversations with patients and nurses, is that it could facilitate the prescription of medications at high risk of overuse or abuse, such as benzodiazepines (BZDs). We conducted a panel data study to investigate, the impact of the introduction of an e-prescribing system on new BZD prescriptions in hospitalised patients in a network of five teaching hospitals. During the observation period 1 July 2014–30 April 2019, 43,320 admissions were analysed. A fixed-effects model was adopted to estimate the effect of e-prescribing on new BZD prescriptions. E-prescribing implementation was associated with a significant increase of new BZD prescriptions: absolute +1.5%, and relative +43% (p < 0.001). The effect was similar in males and females (respectively, absolute +2.3%, relative +65% (p < 0.001); absolute +1.8%, relative +58% (p = 0.01)) and in patients ≥70 years old (absolute +1.6%, relative +59% (p < 0.001)). After controlling for time-varying explanatory variables, the implementation of the e-prescribing tool showed similar significant effects. E-prescribing implementation was associated with a significant increase of new in-hospital BZD prescriptions. For classes of drugs at risk of overuse or abuse, e-prescribing should be used cautiously, to minimize the risk of over-prescriptions. Further research in other settings and countries is needed to analyse causal interactions between e-prescribing and BZD prescriptions in the hospital setting, and to promote the ultimate goal of high-value care.

Background: Cancer and pulmonary circulation disorders represent increasingly intersecting clinical entities. The prevalence of malignancy in patients with pulmonary hypertension (PH), particularly those with chronic thromboembolic pulmonary hypertension (CTEPH), is higher than in the general population. Moreover, cancer and antineoplastic therapies have been implicated in the development of PH through multiple mechanisms. Methods: We performed a systematic review and meta-analysis of the literature focusing on the prevalence of cancer in patients with PH. Mortality incidence and mortality risk were also evaluated for patients with PH with or without cancer. Specific sub-analyses for patients with CTEPH were also performed. Finally, we evaluated the prevalence of PH and its risk of mortality in patients with cancer. Results: Overall, 12 studies including 4402 patients were selected in the quantitative analysis. All the included studies had an observational design. The prevalence of cancer in patients with any PH group was 13% (95% CI: 11–16%); mortality incidence in patients with any PH group and cancer was 41% (95% CI: 26–58%), compared to 10% (95% CI: 1–48%) in those without cancer. The association was even stronger when considering only patients with CTEPH, with a mortality incidence of 4% (95% CI: 2–9%) in those without cancer compared to 19% (95% CI: 8–37%) in patients with cancer (p for difference: <0.01). Finally, prevalence of any PH group in patients with cancer was 22% (95% CI: 15–31%). Conclusions: We observed a possible correlation between PH and cancer, with a significant impact on mortality in patients with PH, particularly those with CTEPH. This association suggests the need for a close clinical surveillance for early detection of cancer and PH.
