Development and validation of a score assessing the risk of severe asthma in primary care.

OBJECTIVE: To develop and validate the Asthma Severity-Health Search (AS-HScore), predicting severe asthma risk in Italian primary care. According to the current asthma treatment guidelines, the AS-HScore intended to serve as a clinical decision support system (CDSS) for General Practitioners (GPs). METHODS: Using the Health Search Database (HSD), a cohort of 32,917 asthma-diagnosed patients between 2013 and 2021 was identified. The AS-HScore was developed using multivariable Cox regression in a two-part cohort: development and validation. Candidate determinants were estimated and linearly combined to form the score; its predictive accuracy was evaluated in the validation sub-cohort. RESULTS: AS-HScore performance in the validation cohort revealed a 73% area under the curve (i.e. discrimination power) and a 22% pseudo-R2 (explained variation). Calibration slope of 1.07 indicated strong calibration without rejecting the equivalence hypothesis (p = 0.157). Estimating a mean 10% (SD: 6.8%) 1-year risk of severe asthma, GPs might be provided with risk thresholds for patient categorization. CONCLUSION: The AS-HScore emerges as an accurate tool predicting severe asthma risk in the Italian primary care. It therefore shows promising application to enhance asthma care by early identification of severe cases. Implementing a score-based CDSS for Italian GPs holds potential for significantly improving asthma management and patients' outcomes.

Perception and knowledge of general practitioners on COPD management according to the GOLD23 document and reimbursement criteria for drugs prescription: an e-Delphi study.

BACKGROUND: COPD management and therapy have been periodically revised to support a more patient-specific approach. Several concerns remain in primary care, such as the proper choice of initial treatment, medication adherence, and missing values for spirometry investigations. These concerns may be exacerbated by inconsistencies between the GOLD23 report and reimbursement criteria, as per the Italian NOTA99, especially for what concerns the assessment of disease severity and related treatment choice. We therefore examined the perception and knowledge of general practitioners (GPs) on COPD management and treatment. METHODS: We conducted an exploratory e-Delphi study among 600 GPs. The study examined the COPD-related GP's access to spirometry evaluations in primary care clinics; knowledge on early recognition of COPD and related clinical concerns; perception of the clinical application of the NOTA99; the place in therapy of the triple LABA/LAMA/ICS combination. RESULTS: Among 466 participating GPs (response rate: 70.3%; mean age 52, SD: 14.2; mean years of experience: 21.3, SD: 15) had a good level of knowledge about the GOLD 2023 document and the reimbursement criteria for COPD medications. Nevertheless, a low (34%) direct access to spirometry was reported, along with absence of consensus on the proper choice of initial treatment (especially of use of LABA/LAMA combination), and the re-evaluation of free-triple therapy LABA/LAMA/ICS through specialist's referral. CONCLUSIONS: This study captured the domains on which further training for GPs might be implemented to improve the management and treatment of COPD. An extension of this e-Delphi to a larger GPs' panel might further confirm these findings.

Expert consensus on the role of OM-85 in the management of recurrent respiratory infections: A Delphi study.

Recurrent infections of upper and lower respiratory tract have an important clinical and economic impact, which can be reduced through appropriate preventive measures, including the use of immunomodulating agents, such as OM-85, which proved to be effective and safe in both adults and children. Although OM-85 can be useful for the prevention of respiratory tract infections, it is still underused in clinical practice. In order to evaluate the level of awareness of the disease burden of recurrent respiratory infections in adults and children and to assess the level of agreement on the prophylactic and therapeutic approach to the disease, including the use of immunomodulants, a Delphi study was performed. A board of six experts in the field of respiratory infections was appointed to elaborate a series of statements covering four main topics (disease, prevention, OM-85, and future strategies), which were thereafter voted by a panel of 30 experts. Results showed that prevention is unanimously recognized as the most important intervention to reduce disease burden, and the use of immunomodulation to improve the effectiveness of vaccination is gaining increasing favor among clinicians. In this respect, OM-85 is recognized as the most studied immunomodulating agent currently available, whose efficacy and safety make it a valuable tool to optimize the management of recurrent respiratory infections in both adults and children. In particular, the combined use of OM-85 and influenza vaccine was recognized as an effective and safe approach to improve the current prevention strategies in order to reduce the burden of recurrent respiratory infections.
