Abstract
Background and Objective. Reports addressing continuous quality improvement (CQI) methods in developing countries are
scant and there are questions about the applicability of quality improvement methods in such settings. The structure and
                                                                                                                                                         Downloaded from by guest on November 13, 2015
output of a formal quality improvement program implemented in a teaching hospital affiliated with the Tehran University of
Medical Sciences is presented.
Objective Method. During a nine-month period, a multi-stage quality improvement program was implemented. It comprised:
(i) training workshops; (ii) a steering committee; (iii) weekly consultation and facilitation of improvement projects; and (iv) a
day-long demonstration and recognition meeting. Four cycles of workshops were held in which 132 employees were trained in
the basics of CQI.
Results. Thirty improvement projects were initiated. Twenty-five of the projects were completed. In an evaluation survey
more than 70% of respondents assessed a ‘positive impact’ on organizational culture, work efficiency and quality of services.
More than 90% believed that the changes were sustained, and more than 60% reported that they have implemented additional
improvement projects.
Conclusion. Our quality improvement package supported rapid implementation of multiple projects. The underlying ‘change
structure’ comprised the improvement teams, top management and the university’s quality improvement office; it integrated
project management, support and facilitation functions by the respective participant. Organization-wide change was more
limited than anticipated. To institutionalize the program and ensure sustainability, a local structure for change should be orga-
nized, management coaching should be sustained, local facilitators should be developed, incentives should be established and
physician involvement should be emphasized.
Keywords: change in behavior, continuous quality improvement, hospital, structure for change
