Identifying patients at risk for loss to follow-up after pain center treatment

Objective. This study was designed to identify, at admission to a pain trea tment facility, characteristics of patients who will be lost to follow-up a fter treatment completion. Method. Patients were divided into 3 groups depending on how they responded to the 12-month follow-up. The analysis was a between-subjects design usin g prospective data collected at a comprehensive pain treatment facility. Lo w back pain patients (n = 168) received 4 weeks of multidisciplinary pain t reatment. The main outcome measure was response/nonresponse to follow-up qu estionnaires. Results. showed that patients who were later lost to follow-up, or who were reluctant to answer follow-ups, could be predicted at treatment admission by measures of pain and functioning. The prediction equation was validated by a second group of patients, treatment noncompleters (n = 55). Conclusion. Chronic pain patients who are more likely to be lost to follow- up can be identified upon admission to a pain facility. Procedures that sho uld decrease follow-up attrition could be implemented at program admission.
