‘Do Not Attempt Resuscitation’ – Do Standardised Order Forms make a clinical difference above hand-written note entries?

Abstract

To quantify any effect of Standardised Order Forms (SOFs), versus hand-written note entries for 'Do Not Attempt Resuscitation'--on the selection and survival of remaining cardiopulmonary resuscitation (CPR) attempts. A prospective, observational study in two UK Hospitals, comparing numbers, demographics and survival rates from CPR attempts for 2 years prior to and 2 years after the introduction of SOFs (the only change in DNAR policy). There were 133 CPR attempts, representing 0.30% of the 44,792 admissions, pre SOFs and 147 CPR attempts representing 0.32% of the 45,340 admissions following the SOFs (p=0.46). The median duration of a CPR attempt was 11min prior to and 15min following the SOFs (p=0.02). Of the CPR attempts, there was no change in mean age (p=0.34), proportions occurring outside working hours (p=0.70) or proportions presenting with an initial shockable rhythm (p=0.30). Survival to discharge following CPR was unchanged (p=0.23). The introduction of SOFs for DNAR orders was associated with a significantly longer duration of CPR (on average by 3-4min) but no difference in overall number, demographics or type of arrest or survival in the remaining CPR attempts.
