QAH HospitalPortsmouth Hospitals NHS Trust Quiz

QAH HospitalPortsmouth Hospitals NHS Trust Page 45/15/2015 VTE: Collective term for:  Deep vein thrombosis (DVT)  Pulmonary Embolism (PE)  Hospital acquired VTE a patient safety priority What is VTE?

QAH HospitalPortsmouth Hospitals NHS Trust Page 55/15/2015 Deep vein thrombosis (DVT) is a thrombus (blood clot) in a deep vein that partially or totally blocks the flow of blood Pulmonary embolism (PE) is a clot that breaks off from the thrombus in the deep vein and moves to the pulmonary artery to block the blood supply in the lungs

QAH HospitalPortsmouth Hospitals NHS TrustPage 75/15/2015

QAH HospitalPortsmouth Hospitals NHS Trust Page 85/15/2015 Also known as ‘The silent killer’  Between % of PEs are rapidly fatal: usually within 2 hours of the onset of symptoms  <50% of PEs are detected prior to death  80% of DVTs are clinically silent

QAH HospitalPortsmouth Hospitals NHS Trust Page 95/15/2015 DVT & it’s complications  Pulmonary embolism (PE)  Death (due to PE)  Post-thrombotic syndrome  Recurrent DVT - 30% chance at 10 years  Pulmonary hypertension

QAH HospitalPortsmouth Hospitals NHS Trust Page 105/15/2015 Post thrombotic syndrome

QAH HospitalPortsmouth Hospitals NHS Trust Page 115/15/2015 Formation of a DVT Starts in the valve pockets of the veins and extends up and down blocking blood flow

QAH HospitalPortsmouth Hospitals NHS Trust Page 125/15/2015 Formation of PE Some of the clot can come loose and break off, travel through the venous system, through the heart and block a blood vessel in the lung

QAH HospitalPortsmouth Hospitals NHS Trust Page 135/15/2015 Virchow’s Triad Being treated as a hospital patient can do all of these things

QAH HospitalPortsmouth Hospitals NHS Trust Signs and Symptoms of DVT  Calf swelling  Pain in the calf, thigh or groin  Engorged veins  Redness and warmth to the skin  Pitting oedema  But remember: up to 80% of DVTs are clinically silent

QAH HospitalPortsmouth Hospitals NHS Trust Signs and Symptoms of PE  Shortness of breath  Pleuritic chest pain  Haemoptysis  Tachycardia  Hypoxia  Fainting  Collapse

QAH HospitalPortsmouth Hospitals NHS Trust Page 165/15/2015 Community acquired thrombosis: CAT Hospital acquired thrombosis: HAT

QAH HospitalPortsmouth Hospitals NHS Trust Page 175/15/2015 Hospital-acquired Thrombosis  There are an estimated 60,000 deaths due to VTE in the UK every year, 65% are estimated to be hospital–acquired  Up to 25,000 preventable deaths a year in the UK due to HAT  10% of all hospital deaths are due to VTE  > 20 times greater than the number of deaths due to MRSA  More deaths than breast cancer, HIV/AIDS and road traffic accidents combined 1

QAH HospitalPortsmouth Hospitals NHS Trust Page 185/15/2015 Hospital-acquired Thrombosis  Can occur whilst the patients are inpatients, indeed they account for 10% of hospital deaths BUT  Majority occur AFTER discharge  Average post-surgical DVT presents on day 7  Average post-surgical PE presents on day 21  Critical ‘at risk’ period – 3 months

QAH HospitalPortsmouth Hospitals NHS Trust Page 195/15/2015 PREVENTION Keep your patients as mobile as possible Stop them from getting dehydrated

QAH HospitalPortsmouth Hospitals NHS Trust Page 205/15/2015 Prevention  Anticoagulants for at risk patients  Extended beyond discharge where appropriate –THR, TKR, Hip #, abdominal or pelvic surgery for cancer, at risk day surgical patients

QAH HospitalPortsmouth Hospitals NHS Trust Page 215/15/2015 Prevention  Consider anti-embolism stockings (AES) and compression devices where indicated

QAH HospitalPortsmouth Hospitals NHS Trust Page 225/15/2015 Remember: no intervention is risk free – risk assessment is essential Stockings can cause harm if used inappropriately, not fitted correctly and not monitored adequately Trust policy and competency for use of AES

QAH HospitalPortsmouth Hospitals NHS Trust Page 235/15/2015 Risk factors for VTE  Surgery  Trauma  Immobility  Malignancy  Cancer therapy (hormonal, chemotherapy etc)  Previous VTE  Family history of VTE  Increasing age  Pregnancy and the postpartum period  COCP or HRT

QAH HospitalPortsmouth Hospitals NHS Trust Page 265/15/2015

QAH HospitalPortsmouth Hospitals NHS Trust Page 275/15/2015 NICE VTE Quality Standard June 2010 No Quality Statement 1All Patients, on admission, receive an assessment of VTE and bleeding risk using the clinical risk assessment criteria described in the National tool 2Patients / carers are offered verbal and written information on VTE prevention as part of the admission process 3Patients provided with anti-embolism stockings have them fitted and monitored in accordance with NICE guidance 4Patients are re-assessed within 24 hours of admission for risk of VTE and bleeding 5Patients assessed to be at risk of VTE are offered prophylaxis in accordance with NICE guidance 6Patients/carers are offered verbal and written information on VTE as part of their discharge process 7Patients receive extended postoperative VTE prophylaxis in accordance with NICE guidance

QAH HospitalPortsmouth Hospitals NHS Trust How are we doing?

QAH HospitalPortsmouth Hospitals NHS Trust

QAH HospitalPortsmouth Hospitals NHS Trust Page 435/15/2015 Report as adverse incident and carry out RCA on all cases of hospital-associated thrombosis (HAT)  Any DVT or PE diagnosed as an inpatient  Any DVT or PE diagnosed within 90 days of an admission  Weekly meeting with Senior Clinicians  Monthly meeting with Chief Nurse & Medical Director –‘avoidable’ incidents  Data to be reported to DoH

QAH HospitalPortsmouth Hospitals NHS Trust HAT Events 2011 by CSC

QAH HospitalPortsmouth Hospitals NHS Trust Readmissions with HAT = potential loss of revenue

QAH HospitalPortsmouth Hospitals NHS Trust Page 475/15/2015 Common Themes 1. Poor documentation of risk assessment (Vitalpac and paper) 2. Delayed or missed doses of chemical prophlyaxis (57% pharmacy audit) 3. Delayed recognition of DVT or PE 4. Lack of patient information provided

QAH HospitalPortsmouth Hospitals NHS Trust Page 485/15/2015  5. Confusion over the concept of mobility and therefore insufficient provision of chemical prophylaxis Significantly Reduced Mobility ‘patients who are bed bound, unable to walk unaided or likely to spend a substantial proportion of their day in bed or in a chair’. NICE definition of mobility:

QAH HospitalPortsmouth Hospitals NHS Trust 6. Failure to consider mechanical prophylaxis when chemical prophylaxis is contraindicated (particularly in medicine) 7. Delayed reporting of VTE event 8. Renal doses 9. Failure to consider obesity doses of LMWH Page 495/15/2015 Treatment doses: 200mg and 75 mg Prophylaxis: Both 40mg?????

QAH HospitalPortsmouth Hospitals NHS Trust Page 505/15/2015 Summary  VTE – major patient safety issue  Majority of events can be prevented with appropriate risk assessment and provision of prophylaxis –Risk assess every patient on admission –Ensure that appropriate prophylaxis is prescribed and administered correctly –Report all cases of HAT in a timely manner –Provide patient information
