“…Numerous studies have reported differences in baseline characteristics between patients captured and those lost to follow-up in clinical registries, and there is concern that this can indicate that attrition bias may exist, especially if the proportion lost to follow-up exceeds 20% [1,13]. Typically, non-respondents in spine registries are younger and have a less favorable health status at baseline, and the proportion of males, smokers, and participants with low socioeconomic status is higher than for respondents [2,5,11,14,17,18]. These differences in baseline characteristics correspond to those observed in the present study.…”

“…A study of 289 patients who underwent minimally invasive surgery at a single center collected 12-month outcome data from 53 (53.5%) of 99 non-respondents (34% of the total sample) through e-mailed surveys or telephone interviews and found that patients lost to follow-up reported greater improvement than those who continued to follow-up [4]. A study of 316 patients operated by a single surgeon with lumbar fusion compared 76 (24%) patients who completed a program of multiple questionnaire-based follow-ups over 2 years with 240 (76%) who responded incompletely [18]. In this study, outcomes were less favorable for patients with incomplete follow-ups.…”

Background The Norwegian registry for spine surgery (NORspine) is a national clinical quality registry which has recorded more than 10,000 operations for degenerative conditions of the cervical spine since 2012. Registries are large observational cohorts, at risk for attrition bias. We therefore aimed to examine whether clinical outcomes differed between respondents and non-respondents to standardized questionnaire-based 12-month follow-up. Methods All eight public and private providers of cervical spine surgery in Norway report to NORspine. We included 334 consecutive patients who were registered with surgical treatment of degenerative conditions in the cervical spine in 2018 and did a retrospective analysis of prospectively collected register data and data on non-respondents’ outcomes collected by telephone interviews. The primary outcome measure was patient-reported change in arm pain assessed with the numeric rating scale (NRS). Secondary outcome measures were change in neck pain assessed with the NRS, change in health-related quality of life assessed with EuroQol 5 Dimensions (EQ-5D), and patients’ perceived benefit of the operation assessed by the Global Perceived Effect (GPE) scale. Results At baseline, there were few and small differences between the 238 (71.3%) respondents and the 96 (28.7%) non-respondents. We reached 76 (79.2%) non-respondents by telephone, and 63 (65.6%) consented to an interview. There was no statistically significant difference between groups in change in NRS score for arm pain (3.26 (95% CI 2.84 to 3.69) points for respondents and 2.77 (1.92 to 3.63) points for telephone interviewees) or any of the secondary outcome measures. Conclusions The results indicate that patients lost to follow-up were missing at random. Analyses of outcomes based on data from respondents can be considered representative for the complete register cohort, if patient characteristics associated with attrition are controlled for.

Background: Patient-reported outcome measures (PROMs) contribute to evaluating and improving the quality of patient care. Patient outcomes after rotator cuff repair (RCR) have been researched; however, the relationship between PROM response rates and individual and health care correlates has not been thoroughly investigated. Purpose: To examine differences in individual and health care factors among patients who had undergone RCR based on their PROM response rates. Study Design: Case-control study; Level of evidence, 3. Methods: Shoulder-specific and general PROMs were solicited via email and text message of all patients who underwent RCR between 2016 and 2020. Three subgroups were classified: (1) complete responders completed all 1-year postoperative PROMs, (2) partial responders answered enough questions to produce ≥1 usable score, and (3) nonresponders did not respond to a single measure. Correlates were assessed using analysis of variance and chi-square tests. Adjusted multinomial logistic regression models identified predictors of 1-year PROM response. Results: Of 2195 patients included at the 1-year follow-up, 34% were complete responders; 11%, partial responders; and 55%, nonresponders. Patients had a mean age of 61.8 years, 63% were men, and 90% were White. Pre- and postoperative PROM scores were similar across responder groups. In stepwise selection, 1-year responses (complete or partial) were associated with older age, later year of surgery, White race, and having workers’ compensation insurance. The strongest predictor of PROM response was having workers’ compensation insurance. Conclusion: Patients with workers’ compensation insurance compared with other insurance types responded to PROMs at disproportionately higher rates. This could distort postoperative PROM scores in the population studied because there are known differences among patients with this insurance status.
