RR280 - Real time evaluation of health and safety management in the National Health Service
The design of an impact evaluation of a health and safety
management system in the National Health Service (NHS) was informed
by a review of relevant literature, which identified a design
comprising six main aspects. These were a longitudinal design;
inclusion of comparison groups; an intervention that was of
interest to the NHS; a participative style; multiple measurement
methods and multiple indicators of effectiveness.
Field study data was generated using a prospective longitudinal
before-and-after design with a multiple baseline. Seven NHS Trusts
participated; two of which were used as comparison groups. The
intervention was a safety management workbook, introduced only to
the test group. Evaluation of the workbook impact on safety
performance involved two identical phases, approximately 12 months
apart. Each phase comprised of a staff opinion questionnaire
survey, based on previously validated work; and a new HSE
methodology involving analysis of accident data to derive costs,
which could be linked to management root causes.
The most frequently encountered system failure was that of risk
assessment, with planning, implementing, measuring and reviewing as
the main root causes. Estimated extrapolated costs were between
0.06% and 1.44% of the running costs of the NHS. Responses from the
questionnaires showed significant differences between the Trusts
and a significant improvement in staff opinion in some safety
