Implementation of a high volume, complex clinical pathway for cardiothoracic surgery patients in the intensive care unit. Marion van der Kolk Surgeon/Intensivist UMC St Radboud, Nijmegen The Netherlands
Cardio thoracic surgery High volume, high risk Dedicated ICU/MC/Ward 68% of deaths in this patient group in post-op ICU ( v Heede etal 2009, Int J Nurse Stud 46(6) 796-803) Clinical pathways rarely start in the ICU
Clinical Pathway Generally expressed as a day-to-day-care plan describing all multidisciplinary activities In the intensive care unit (ICU) a clinical pathway implicates an hour-to-hour care plan
The cardiothoracic ICU patient Starting a path
Pre-implementation Clinical Pathway ICU organization cardiothoracic surgery 16 beds: intensivists, fellows, residents, nurses, providers (surgeons, cardiologists) Barriers and opportunities Selection of key-nurses Education and training Heart surgery database (corrad)
Barriers and Risks Collaboration: Cardiothoracic surgeons vs Cardiologists vs Intensivists NICE: information of intensivists was not taken seriously Education aspect for residents Tradition: doctors autonomy Evidence 2005-2006 was a turbulent time for our organization
Opportunities Head of the department of Intensive Care: total commitment Chances for nurses Radboud variance model made is possible to act fast (pro-active) The hour-to-hour care plan, together with the medical protocol made it possible that responsibilities could be taken by nurses within a legal setting
Method to build a clinical pathway 1 Population: Cardiothoracic Surgery 2 Literature review 6/8 Key nurses and intensivist: clinical activities and development of Radboud variance model Education Eight step method to build a pathway. Not in our minds at that time Lodewijckx etal trials 2012 13:229
Clinical Pathway and Variance model
Variance report
Predefined goals Incidence of temperature drop >0.3 o C after arrival on the ICU Electrolytes in range Duration of weaning from the ventilator Extubation time Time to mobilization Nutrition intake
Overall variances measured Blood pressure and hemodynamic parameters Atrial fibrillation Thoracic drain output Diuresis Temperature Pain Sedation Start weaning Extubation Shivering Mobilisation etc etc.

Results Weaning time decreased significantly following the implementation of the clinical pathway Extubation time decreased significantly The day following surgery all included patients resumed normal nutrional intake and were mobilized, which was one day sooner than in the non-clinical Pathway group
Results: Clinical pathway group Over 90% of the control patients needed electrolyte or adequate blood pressure regulation, which was not started in time In contrast: Over 90% in CP group received timely and adequate treatment Nurses acted faster when abnormal drain production occured

RISK-ADJUSTED MORTALITY ANALYSIS Cussum score Q1-Q3 2012
Conclusions Clinical pathway in the intensive care unit is feasible Adherence can be measured Radboud variance model enables nurses to act fast and within a save and legal setting Clinical benefits appear to be likely Hard data on morbidity and mortality will be difficult to correlate
Where do we stand and the future CP high volume high risk is used as blue print to develop CP s for low volume-high risk populations: Implementation of preoperative optimization of esophageal resection 2008 and 2011 was succesfull (ICU path) CP (Intensive care and Surgical ward) for esophageal resection with preoperative optimization has been implemented in september 2011 Post Anesthesia Care Unit/ICU/Ward implementation of peri-operative care for Whipple procedure is starting. HIPEC, Liver surgery, etc will follow Know the strengths and weaknesses of your wards
