Introduction Osteoporosis and fragility fractures represent a major health problem that is expected to become increasingly significant in the future. Fragility fractures have serious consequences for patients, increasing the risk of refracture, morbidity and mortality. Despite the availability of numerous effective drugs and validated AIFA nota 79 prescription criteria, a considerable treatment gap for osteoporosis persists, with the majority of eligible patients remaining untreated. A number of strategies have been proposed to reduce this therapeutic gap, particularly in the context of secondary prevention, i.e., in patients who have already experienced a fracture. These are referred to as Post-Fracture Care models, with the Fracture Liaison Service (FLS) representing the most prominent example. Materials and methods The present study evaluated the effectiveness of the Hip-POS program, the FLS model implemented in Padua, in reducing the treatment gap. Anthropometric, clinical, laboratory and personal data, and risk factors for bone fragility, collected through this program between March 2023 and March 2025 have been evaluated. How many patients were already undergoing treatment for osteoporosis and how many had an existing indication for treatment or for undergoing DEXA before the index fracture has been assessed. Furthermore, how many patients had a non-low FRAX score (a fracture risk assesment tool) has been evaluated. Finally, the study analyzed the effectiveness of the Hip-POS model in improving adherence to antiresorptive therapies, as poor adherence remains one of the key contributors to the treatment gap. Results and Discussion The study included 1,103 patients (71.6% female) with a mean age of 83.3±9.1 years, assessed following a fragility-related hip fracture between March 2023 and March 2025. Only 7.4% were already receiving osteoporosis treatment at the time of the fracture, although 18.6% had an indication for treatment prior to the fracture according to AIFA’s NOTE 79, 51% met LEA criteria for DEXA reimbursement, and 92.9% had a non-low FRAX risk. These data show that many patients could have been identified and treated before the index fracture. Moreover, the Hip-POS model proved effective in reducing the treatment gap: following FLS assessment, the proportion of treated patients increased from 7.4% to 68.9%. The 12-month follow-up, available for 372 patients, showed a generally high rate of treatment adherence, with 77.4% of patients still receiving osteoporosis medications after one year.
Introduzione L’osteoporosi e le fratture da fragilità rappresentano un problema socio-sanitario destinato ad assumere nei prossimi anni sempre più importanza. Le fratture da fragilità presentano importanti ripercussioni sul paziente, aumentando il rischio di rifrattura, di morbilità e di mortalità. Nonostante i numerosi farmaci oggi a disposizione, la loro documentata efficacia, e la prescrizione normata e validata dalla nota 79 dell’AIFA, persiste un considerevole “Treatment Gap” per l’osteoporosi, per cui la maggior parte dei pazienti avente una chiara indicazione non viene trattata. Sono state ipotizzate diverse strategie per ridurre questo gap terapeutico, soprattutto in prevenzione secondaria, ossia in pazienti che hanno già sperimentato la frattura. Si parla in questo caso di modelli di Post Fracture Care, di cui il Fracture Liaison Service (FLS) rappresenta il modello di riferimento. Materiali e Metodi Il presente studio ha valutato l’efficacia del programma Hip-POS, il modello FLS dell’Azienda Ospedale-Università di Padova, nel ridurre il treatment gap per l’osteoporosi. Sono stati raccolti i dati provenienti da questo programma tra Marzo 2023 e Marzo 2025, valutando i parametri anagrafici, antropometrici, clinici, di laboratorio e i fattori di rischio per fragilità scheletrica. Si è quindi valutato quanti pazienti erano già in terapia per l’osteoporosi e quanti presentavano già indicazione al trattamento o all’esecuzione della densitometria ossea (DEXA) prima della frattura indice. Si è analizzato anche quanti pazienti presentavano un rischio di frattura a 10 anni calcolato con FRAX score (uno strumento di valutazione del rischio di frattura) non basso. Infine, è stata valutata l’efficacia del modello Hip-POS nell’aumentare il tasso di trattamento dell’osteoporosi e nel migliorare l’aderenza terapeutica per i farmaci anti-riassorbitivi, che rappresenta ad oggi una delle cause del treatment gap. Risultati e Discussione Lo studio ha incluso 1103 pazienti (71.6% di sesso femminile) con età media 83.3±9.1 anni, valutati a seguito di frattura femorale da fragilità. Solo il 7.4% di questi era già in terapia per l’osteoporosi, ma il 18.6% aveva indicazione al trattamento prima della frattura secondo la NOTA 79 dell’AIFA, il 51% presentava i criteri LEA per il rimborso della densitometria e il 92.9% presentava un rischio FRAX non basso. Molti pazienti avrebbero potuto quindi essere identificati e trattati prima della frattura indice. Inoltre, il modello Hip-POS si è dimostrato efficace nel ridurre il treatment gap; infatti, a seguito di valutazione FLS è aumentata la percentuale dei pazienti trattati dal 7.4% al 68.9%. Il follow up a 12 mesi, disponibile per 372 pazienti, ha rivelato che il tasso di aderenza era generalmente elevato, con il 77.4% dei pazienti ancora in terapia a distanza di un anno dall’inizio del trattamento.
