Confronto fra modelli di ostetricia diretti da levatrici e altri modelli, basato sulla sintesi di 15 studi con 17'700 casi, Cochrane Librery, aprile 2016 unche conferma quanto sosteniamo da tempo (v. lo studio QUI)

Studi recenti sulle cure ostetriche dirette da levatrici

• Una recente pubblicazione (Cochrane Review) giunge alla conclusione che le donne assistite con cure ostetriche gestite da levatrici, presentano esiti migliori dal punto di vista della salute che non quelle seguite con il modello di assistenza medica convenzionale. Vedi qui.

• La prestigiosa rivista scientifica Lancet ha recentemente pubblicato un’analisi dei costi di un sistema di cure ostetriche gestite da levatrici. I risultati di questa ricerca hanno mostrato che questi modelli sono altrettanto sicuri, ma meno costosi dell’assistenza medica convenzionale. Vedi qui.

• Questi importanti risultati sono riassuntie e commentati nelle seguenti pubblicazioni: „The conversation“ come pure “The Independent“
