Scoping our Practice The 2004 Report of the National Confidential Enquiry into Patient Outcome and Death Elements of the study • Deaths within 30 days of a therapeutic endoscopy • Complications (incl. death) following upper GI dilation and tubal prosthesis insertion (includes denominator data) • Organisational questionnaire GI therapeutic endoscopy - method • All deaths April 2002 - March 2003 reported to NCEPOD • Sample cases identified by OPCS codes and included if death occurred within 30 days of procedure • Retrospective data - questionnaires and case note extracts Data overview Patient assessment Patient assessment • 91% admitted as emergencies • 76% had 2 or more comorbidities • 74% of deaths were either a ‘definite risk’ or ‘expected’ Patient assessment • 86% of procedures were appropriate • 83% of procedures were timely • 9% of procedures were either futile or too late to be of any benefit Recommendation Patients must be assessed by the referring clinician and the endoscopist to justify that the procedure is in the patient’s interest. (Professional specialist associations) Training and education Training and education Experience • 74% of procedures performed by consultants, some doing less than 20/ year • 94% appropriate grade • 91% appropriate experience Training and education Supervision • 88% - senior endoscopist in hospital • 18% - direct supervision Audit • 78% of procedures in hospitals that held audit meetings • 26% of cases reviewed Recommendations There should be national guidelines for assuring continuing competency in endoscopy. (Professional specialist associations) All endoscopy units should perform regular audit and all deaths during, or within 30 days of, therapeutic endoscopy should be reviewed. (Local hospitals; Professional specialist associations) Recommendations (cont.) All those responsible for the administration of sedation should have received formal training and assessment. (Local hospitals) Patient consent Consent Consent Recommendation The risks and benefits of therapeutic endoscopy should be explained to the patient, and this should be documented on the consent forms as laid down in the Department of Health guidelines. (Local hospitals) Consent 16% of patients studied had dementia or acute confusion Recommendation The ability of those with dementia or acute confusion to provide consent should be tested and clearly documented. (Local hospitals) Sedation and monitoring Sedation and monitoring Sedation and monitoring • 14% of patients received inappropriate sedation • 14% of those that received sedation required a reversal agent afterwards A patient with severe alcoholic liver disease, Childs-Pugh C, and bacterial peritonitis had undergone previous gastroscopies for bleeding. Bleeding continued and an endoscopist who had received training in sedation, performed what was the patient’s second gastroscopy in two days. Sedation comprised IV midazolam 5mg and further IV midazolam 2mg. Pulse oximetry was recorded as 87-91% during the whole of the procedure and flumazenil was used to reverse the effects of midazolam following it. Sedation and monitoring A patient was admitted with an acute inferior myocardial infarction. Four weeks later the patient suffered a large haematemesis, became hypotensive and their haemoglobin decreased by 2.5 gm/dl. A CVP line was inserted to monitor resuscitation. The next day an endoscopy was performed and adrenaline was injected into two large gastric ulcers. Pulse oximetry and automatic blood pressure were monitored, but ECG was not. Sedation and monitoring Recommendations Sedation and monitoring practices within endoscopy units should be audited and reviewed. (Local hospitals; Professional specialist associations) There should be national guidelines on the frequency and method of the recording of vital signs during the endoscopy. (NPSA; Professional specialist associations) Recommendations (cont.) Clear protocols for the administration of sedation should be available and implemented. (Local hospitals) Percutaneous endoscopic gastrostomy (PEG) PEG Indication • Neurological disorders of swallowing • Cognitive impairment/depressed consciousness • Mechanical obstruction to swallowing • Long-term partial failure of intestinal function requiring supplemental intake PEG Profile • In 59% of cases the indication included acute neurological disease (stroke/trauma) • 82% were 70 years of age • 84% were ASA 3 or poorer • 95% were elective/scheduled procedures PEG Patient selection and timing • 19% of PEG procedures were thought to be futile • 40% had a co-existing diagnosis of chest infection • 18% had dementia • 43% died within 7 days In one case where a patient was over 90 years-of-age an advisor commented: “The PEG placement was technically OK - but the timing was wrong. The patient was very ill, dehydrated and had pneumonia. They should not have had a PEG at this time and died six days later. There is no information about the last few days of life.” Recommendations The decision to use a PEG feeding tube requires an in-depth assessment of the potential benefits to the individual. All patients in whom PEG feeding is proposed should be reviewed by a multidisciplinary team. (NICE) There is a need for more comprehensive national guidelines for the use of PEG feeding, including issues of patient selection. (NICE) Endoscopic retrograde cholangiopancreatography (ERCP) ERCP Profile • 82% 70 years of age • 77% were ASA 3 or poorer • 87% received prophylactic antibiotics • 68% were considered futile ERCP Procedure • 97% performed by consultants • 11% of cases by endoscopist who performed < 50 ERCPs/year • 92% involved the biliary tract ERCP Complications • In 9% of cases during the procedure • 64% of patients had one or more complications in the 30 days following ERCP Recommendation Patients should be reviewed by the consultant endoscopist before therapeutic ERCP to ensure that the procedure is appropriate and the patient’s condition has been optimised. (Local hospitals) Oesophagogastroduodenoscopy (OGD) OGD Profile • 44% of sample cases • 61% 70 years of age • 44% bleeding varices • 35% stricturing disease in oesophagus • 20% ulcer disease OGD Treatment • sclerotherapy, coagulation, banding Complications • haemorrhage, respiratory and cardiac Upper GI haemorrhage Upper GI haemorrhage • 86% needed emergency/urgent endoscopy • In 89% of cases there was a definite or expected risk of death • 94% of endoscopists were GI specialists • 25% had both topical anaesthesia and intravenous sedation Upper GI haemorrhage • 92% of cases were appropriate and timely and in the correct location for both procedure and recovery • 73% had good ‘overall’ care • clinical factors • organisational factors An elderly patient with cirrhosis (no cause stated) and ischaemia related biventricular failure presented with a haematemesis that was not considered to be severe by the admitting clinician as the “urea is only 6.5”. The patient was tachypnoeic, tachycardic and hypotensive. Before endoscopy, the patient did not receive either supplemental oxygen or intravenous fluids - which in view of the cardiac condition should have been governed by central venous monitoring. Recommendations Only experienced endoscopists should treat patients with upper GI haemorrhage. Experience will vary by grade but competence should be assessed by the supervising consultant. (Local hospitals) Recommendations (cont.) Optimising the patient’s preendoscopy condition will reduce both morbidity and mortality. Early involvement of an anaesthetist/intensivist if necessary will assist this. (Local hospitals) Pathology Reporting deaths to the coroner and autopsy rates Total autopsies - 144 (8% of all deaths) Autopsy rates comparison NCEPOD study England & Wales national averages - all deaths • 38% deaths • 27% deaths reported reported • 30% accepted for • 58% accepted for autopsy autopsy Evaluable autopsy reports • Clinical history present in 86% of cases (increase on previous NCEPOD studies) • Gross description ‘satisfactory’ or better in 89% of cases (increase) • Histology taken in 37% of cases (increase) • Clinico-pathological summary absent or poor in 44% of cases (same) ONS cause of death formulation • 1a. Disease, due to • 1b. Disease, due to • 1c. Fundamental pathological cause of death • 2. Other diseases contributing to death, but not the main cause ONS • Wrong structure = 13% • Wrong cause of death = 34% Main deficiencies in cause of death • Omitting the operative procedure • Lazy thinking on sequence of events • Leaving out fundamental pathology (e.g. cancer) • Attributing death to ‘ischaemic heart disease’ instead - convenient but probably not true In an otherwise excellent report, including histology, of a patient who died of cholangiocarcinoma, and who also had documented 60-70% stenoses of the coronary arteries, the cause of death was stated to be: 1a. Myocardial insult due to anaemia following ERCP (August 2002) 1b. Ischaemic heart disease Better would be: 1a. Cholangiocarcinoma (ERCP August 2002) 2. Ischaemic heart disease Recommendations The operative procedure should be included in the cause of death statement. (Undergraduate and postgraduate deans; ONS) Post-procedure deaths (i.e. those occurring during or within 24 hours of anaesthesia or sedation or those where it is known that the procedure is implicated in the death) should be reported to the coroner. (Local hospitals) Recommendations (cont.) Pathologists should think more carefully about all the clinical circumstances of a death, to produce an autopsy report more useful for clinical governance and audit. (Professional specialist associations particularly the Royal College of Pathology) NCEPOD supports the reforms of the coronial and death certification systems, which will result in better scrutiny of deaths. (Home Office) Additional recommendations Organisational issues Hospitals should ensure that the appropriate monitoring equipment and resuscitation equipment is available in each of their endoscopy rooms and recovery areas. (Local hospitals; Primary Care Trusts) In order to produce optimal care for what is a large group of severely ill patients, hospitals should consider establishing formal on-call arrangements. (Local hospitals) Upper GI dilation and tubal prosthesis insertion A national audit across all specialties of specific techniques and equipment that is used for upper GI dilation and tubal prosthesis insertion is indicated.
