60 Nuclear Medicine Part 9. Quality Assurance60 How to get a new Gamma camera?

61 Nuclear Medicine Part 9. Quality Assurance61 PURCHASE GROUP Nuclear medicine specialist Nuclear medicine technologist Medical physicist Medical engineer Person from the hospital administration

62 Nuclear Medicine Part 9. Quality Assurance62 How to open the safe? Careful analysis of the need and state the reasons for the purchase of the gamma camera Establishment of a nuclear medicine service Increased volume of patients The technical performance is not good enough for new methods No spare parts available Unrepairable

63 Nuclear Medicine Part 9. Quality Assurance63 How many cameras? As an example, let us assume that in a certain region of a country having a stable population of there are plans to establish a nuclear medicine facility. The mean number of examinations in the country is 15 per 1000 population and year but the new department should be designed to fulfil a future need of 20 per 1000 population, which means that the total number of examinations will be 3000 per year or 60 per week

64 Nuclear Medicine Part 9. Quality Assurance64 Basic calculation *) depends on the type of camera

65 Nuclear Medicine Part 9. Quality Assurance65 If we assume that the number of hours per week a gammacamera can be effectively used for patient examinations to be 28 (70% of 40) then the number of cameras should be 66/28=2.4. This figure should be further corrected by taking into account the time needed for regular maintenance of the equipment as well as unplanned stops due to different failures. Result Number of cameras

Safety culture Support from the hospital management Well educated staff Local radiation protection organization Quality assurance programme Use of authorized services Continuing education and training Arrangements for individual monitoring and health surveillance Records Documented local rules and procedures

94 Nuclear Medicine Part 9. Quality Assurance94 Education and Training are essential for a radiation protection programme l As part of a the implementation of a Radiation Protection Programme (IAEA TECDOC 1040, 2.2.1): “Early in the process a decision should be made about additional training required for the hospital staff…” l The relevant plan should include who, where and when shall be trained.

95 Nuclear Medicine Part 9. Quality Assurance95 Responsibility of the licensee l BSS 2.30.: “Provision shall be made for reducing as far as practicable the contribution of human error to accidents and other events that could give rise to exposures, by ensuring that: (a)all personnel on whom protection and safety depend be appropriately trained and qualified so that they understand their responsibilities and perform their duties with appropriate judgement and according to defined procedures;”

96 Nuclear Medicine Part 9. Quality Assurance96 Education l All staff in nuclear medicine must have appropriate education to perform their duties… l For radiation protection purposes this affects particularly: n Radiation Protection Officer n Physician n Qualified Expert (Medical Physicist) n Nuclear Medicine Technician n ….

97 Nuclear Medicine Part 9. Quality Assurance97 Personnel shall be instructed in radiation protection before assuming duties: the conditions of the licence; safe use and operation of equipment; instructions that should be provided to patients and patient helpers; institutional radiation protection policies and procedures (including emergency practice drills); the local QA programme and QC procedures; the results of review and analysis of incidents and accidents that have occurred in the institution or elsewhere. Education and training

98 Nuclear Medicine Part 9. Quality Assurance98 A note of qualifications of others l There should also be a process in place which ensures that outside contractors on whom radiation protection may depend (e.g. service engineers) are appropriately trained and qualified.

99 Nuclear Medicine Part 9. Quality Assurance99 EDUCATION AND TRAINING In addition to the staff working within the nuclear medicine department, the following staff should receive instruction from the RPO: nurses in wards with radioactive patients; staff who do not belong to the nuclear medicine practice but need to enter controlled areas; and staff who transport radioactive patients or radioactive materials within the institution.

100 Nuclear Medicine Part 9. Quality Assurance100 EDUCATION AND TRAINING * Basic and continuing training for those who have responsibilities for the operation of the equipment or for preparations of radio- pharmaceuticals. * Advanced training for physicians, physicists and radiochemists. * Continuing education for those who have operational responsibilities in a nuclear medicine facility.

101 Nuclear Medicine Part 9. Quality Assurance101 Continuing Education l It is essential for all staff to have regular updates on radiation protection aspects l Continuing education must be documented

102 Nuclear Medicine Part 9. Quality Assurance102 Education and Training l If the number of professionals is too small to justify setting up a training course, then international co-operation programs may be used l Distance learning programs may be useful l A course such as the present may play an important role...

103 Nuclear Medicine Part 9. Quality Assurance103 EDUCATION AND TRAINING Continuing education in annual refresher training courses, and whenever there is a significant change in duties, regulations, terms of the license, or type of radioactive material or instruments used. Topics should be selected from a syllabus which has been approved by the RPC. Today we will talk about Patient safety

104 Nuclear Medicine Part 9. Quality Assurance104 Radiation protection training programme Basic radiation physics. Biological effects of radiation. International standards in Radiation Protection Responsibility and duties. Safe handling of radioactive materials. Occupational radiation protection. Medical exposure. Management of radioactive waste. Protection of the public. Emergency preparedness. Organization of radiation protection

105 Nuclear Medicine Part 9. Quality Assurance105 Training Record The records should include the following information: (a) Name of the person(s) who delivered the instruction or training; (b) Name of the person(s) who received the instruction or training; (c) Date and duration of the instruction or training; (d) List of the topics addressed; (e) Copy of the certificates of training

106 Nuclear Medicine Part 9. Quality Assurance106 Education & Training l The Regulatory Authority should establish training curricula for (for example) :  RPOs  members of the RPC  relevant physicians  medical physicists  laboratory staff

107 Nuclear Medicine Part 9. Quality Assurance107 The role of Regulatory Authority  Require key personnel (named in RPP) to be duly accredited/qualified and to have adequate training in radiation protection.  Specify/approve minimum training standards/syllabus content for radiation protection training courses.  Provide training courses, perhaps in conjunction with other contributors, if courses are otherwise unavailable in the country.

108 Nuclear Medicine Part 9. Quality Assurance108 Continuous Quality Improvement l CQI - many other acronyms are available for this l Part of virtually all QA systems l Improved methods are documented in clinical trial reports. l Quality assurance protocols are continuously under development in many countries l Regular Quality Assurance meeting for all members of a Section l Continuing education - lectures, workshops, journal clubs and must be available for all staff

109 Nuclear Medicine Part 9. Quality Assurance109 And finally: QA is not a threat, it is an opportunity l It is essential in a QA program that all staff feel free to report errors l A non threatening environment must exist l Reward honesty with encouragement l Education is the key, not punishment

110 Nuclear Medicine Part 9. Quality Assurance110 What is this? Communication!

111 Nuclear Medicine Part 9. Quality Assurance111 Questions?

112 Nuclear Medicine Part 9. Quality Assurance112 DISCUSSION How should the quality of a nuclear medicine practice be measured?
