Impact of repeated hospital accreditation surveys on quality and reliability, an 8-year interrupted time series analysis.

ABSTRACT:

Objective

To evaluate whether hospital re-accreditation improves quality, patient safety and reliability over three accreditation cycles by testing the accreditation life cycle model on quality measures.

Design

The validity of the life cycle model was tested by calibrating interrupted time series (ITS) regression equations for 27 quality measures. The change in the variation of quality over the three accreditation cycles was evaluated using the Levene's test.

Setting

A 650-bed tertiary academic hospital in Abu Dhabi, UAE.

Participants

Each month (over 96 months), a simple random sample of 10% of patient records was selected and audited resulting in a total of 388 800 observations from 14 500 records.
