Pre-CRT implantation, 83% of all patients had been hospitalised for a total 248 hospitalisation events. Following CRT, 47 patients (27%) were readmitted to hospital within 1\u2009year (total of 98 admissions; p&lt;0.01 compared with pre-device implant). Length of hospital stay was significantly shorter than in the year prior to CRT implantation at a median of 4 (IQR 2\u20136) vs 7 (IQR 3.5\u201310.5) days (p=0.03). An increase in the median number of DAOH was observed from 362 (IQR 355\u2013364) to 365 (IQR 364\u2013365) (p&lt;0.01) after CRT implant. The improvement in DAOH was seen regardless of gender and type of CRT devices. Greater DAOH was also seen in those with non-ischaemic cardiomyopathy and Caucasians.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>After CRT implant, patients with HF have greater DAOH with reduction of total hospitalisation and fewer hospital days.
