Can benchmarking be applied to radiation protection? And is it useful?

PURPOSE

Any program of protection from the ionizing radiations used for health care must ultimately lead to the total prevention of graduated effects and to the limitation of probabilistic effects to acceptable levels. The latter are the more dangerous because they may occur even at very low doses and involve the whole population including unexposed subjects; these effects may appear in the generations to come. The specific protection of the health of operators, patients, and the general population, depends on a series of physical-technical and bureaucratic-administrative factors. These must be known and applied based on precise reference standards, recommended or stated by law, as well as on appropriately regulated and controlled procedures. We chose to apply the benchmarking method to radiation protection in order to standardize and increase the efficacy of prevention and to plan, according to Deming's cycle, the continuous improvement of radiation protection performance.

METHOD

Benchmarking is a qualitative intercomparison method widely used in business economics to improve performance referring to best practice and the best in class. When applied in a department where all the partners belong (internal benchmarking), the method features a subdivision into different (sub)processes integrated according to the logic of problem-solving. These stages are: planning: 1) identifying benchmarking issues; 2) identifying the participants; 3) deciding the data collection method; 4) data collection; analysis: 5) measuring the gap; 6) planning future performance; integration: 7) reporting the results; 8) setting the functional goals; action: 9) developing and implementing plans; 10) checking results and resetting the target. The gross subdivision of resources into human and structural permits to check the gap between an actual and an ideal setting separately. Thus, the procedures will give information on the human factor which will be periodically checked in loco relative to all active and passive conducts, while standards will be used to assess the available spaces, facilities and equipment, as well as the relative regular activity. Specific physical-technical and bureaucratic-administrative indices will be needed in both cases.

RESULTS AND DISCUSSION

Solving the operators' doubts and consequently decreasing the statistical errors and/or the cases of incorrect performance has resulted in improved rendered quality, which will be further increased after the planned replacement of substandard or unsafe equipment. Meanwhile, the early application of equipment quality controls has helped rationalize and markedly decrease maintenance costs, which results in possible technologic investment to improve emergency imaging. Greater attention to their protection has made patients feel an improvement in received quality and has increased empathy in general. Total quality, as compared with the best practice, has increased thanks to the positive stimulus from standardization, emulation and sharing, and not only to the controls performed. It is difficult to evaluate the management indices, especially the performance efficacy, that is the relationship between radiation protection and results, because the work is in progress and we still lack the actual data on the decrease in accidents at work or occupational diseases of the operators. Moreover, the epidemiological data on radiation-induced conditions will be difficult to collect and interpret, which will make the dynamics of lawsuits for unwarranted or excessive exposure a useful and more readily available piece of information. Finally, relative to economic results, we would like to stress that no additional costs have been necessary to implement safety and quality in a setting involving, directly or indirectly, thousands of people.
