Incomplete or delayed referrals from primary care providers to specialty care can cause diagnostic delays and patient harm. A systems engineering analysis was conducted to identify vulnerabilities in the referral process and develop a framework to close the loop between primary and specialty care. Low reliability processes, such as workarounds, were identified and human factors approaches were recommended to improve successful referral rates.
