Abstract Objectives Mandatory newborn screening (NBS) for spinal muscular atrophy (SMA) was implemented for the first time in Italy at the end of 2021, allowing the identification and treatment of patients at an asymptomatic stage. Methods DNA samples extracted from dried blood spot (DBS) from newborns in Apulia region were analysed for SMA screening by using a real‐time PCR‐based assay. Infants harbouring homozygous deletion of SMN1 exon 7 confirmed by diagnostic molecular tests underwent clinical and neurophysiological assessment and received a timely treatment. Results Over the first 20 months since regional NBS introduction, four out of 42,492 (0.009%) screened children were found to carry a homozygous deletion in the exon 7 of SMN1 gene, with an annual incidence of 1:10,623. No false negatives were present. Median age at diagnosis was 7 days and median age at treatment was 20.5 days. Three of them had two copies of SMN2 and received gene therapy, while the one with three SMN2 copies was treated with nusinersen. All but one were asymptomatic at birth, showed no clinical signs of disease after a maximum follow‐up of 16 months and reached motor milestones appropriate with their age. The minimum interval between diagnosis and the treatment initiation was 9 days. Interpretation The timely administration of disease‐modifying therapies prevented presymptomatic subjects to develop disease symptoms. Mandatory NBS for SMA should be implemented on a national scale.

Objectives Evidence showed that, even in high-income countries, children and adolescents may not receive high quality of care (QOC). We describe the development and initial validation, in Italy, of two WHO standards-based questionnaires to conduct an assessment of QOC for children and young adolescents at inpatient level, based on the provider and user perspectives.Design Multiphase, mixed-methods study.Setting, participants and methods The two questionnaires were developed in four phases equally conducted for each tool. Phase 1 which included the prioritisation of the WHO Quality Measures according to predefined criteria and the development of the draft questionnaires. In phase 2 content face validation of the draft questionnaires was assessed among both experts and end-users. In phase 3 the optimised questionnaires were field tested to assess acceptability, perceived utility and comprehensiveness (N=163 end-users). In phase 4 intrarater reliability and internal consistency were evaluated (N=170 and N=301 end-users, respectively).Results The final questionnaires included 150 WHO Quality Measures. Observed face validity was excellent (kappa value of 1). The field test resulted in response rates of 98% and 76% for service users and health providers, respectively. Among respondents, 96.9% service users and 90.4% providers rated the questionnaires as useful, and 86.9% and 93.9%, respectively rated them as comprehensive. Intrarater reliability was good, with Cohen’s kappa values exceeding 0.70. Cronbach alpha values ranged from 0.83 to 0.95, indicating excellent internal consistency.Conclusions Study findings suggest these tools developed have good content and face validity, high acceptability and perceived utility, and good intrarater reliability and internal consistency, and therefore could be used in health facilities in Italy and similar contexts. Priority areas for future research include how tools measuring paediatric QOC can be more effectively used to help health professionals provide the best possible care.
