The Joint Commission International Accreditation (JCIA) is perceived worldwide as the symbol of exceptional quality of care. Despite the popularity of international accreditation, evidence of its effectiveness on improving health care quality is inconclusive. This dissertation research utilized a Convergent parallel mixed method framework to evaluate the impact of the JCIA process on quality and to identify the factors that influence the effectiveness of this process at King Fahd Hospital of the University in Khobar, Saudi Arabia. An interrupted time series analysis was conducted to assess the changes in a total of 12 quality outcomes pre and post accreditation. Furthermore, a qualitative approach was used to investigate the attitudes and perceptions of 31 health providers towards this process and the factors that influence its success.

The quantitative results suggested that the JCIA had a positive impact on 9 out of 12 outcomes. The improved quality outcomes included: the average length of stay, the percentage of hand hygiene compliance, the rate of nosocomial infections, the percentage of radiology reporting outliers, the rate of pressure ulcers, the percentage of the correct identification of patients prior to medication administration, the percentage of critical lab reporting within 30 minutes, and the bed occupancy rate.  The outcomes that did not improve were the rate of patients leaving the ER without being seen, the percentage of OR cancelations on the day of the or and the rate of patient falls.

The qualitative analysis suggested that the JCIA was perceived positively by all participants. Some of the perceived advantages of international accreditation included the transformation of the organizational culture to a culture that promotes continuous quality improvement, standardization, and the reduced paperwork in some departments. The participants’ responses also indicated that there were many factors that influence the success of the process. Examples of the factors identified in the study include the increased workload and the providers’ resistance to participate in the JCIA process. In conclusion, international accreditation seemed to have a positive impact on quality outcomes and was received positively by providers. Nevertheless, the factors that hindered the JCIA process need to be addressed by the hospital’s leadership to ensure more efficient quality improvement efforts during future accreditation cycles.
