What PROMIS Scores Correlate With Severe Disability in Cervical Spine Surgery?

Institutional Review Board-approved prospective cohort study. To establish a conversion between Neck Disability Index (NDI) and Patient-Reported Outcomes Measurement Information System (PROMIS) Pain Interference (PI). As the National Institutes of Health (NIH) PROMIS is a global outcome measure, it can be difficult to interpret the clinical implications in patients with cervical spine surgery. To determine how a disease-specific legacy instrument (NDI) correlates with PROMIS PI and define levels of substantial and minimal disability, we developed a formula to convert NDI scores to PROMIS PI. Adult patients undergoing cervical spine surgery at a single institution from 2016 to 2018 were prospectively enrolled. Patients undergoing surgery for instability due to trauma were excluded. Preoperative questionnaires, demographic data, presenting complaint (radiculopathy, myelopathy, myeloradiculopathy), and procedural data were recorded. Patients were included if they had completed the NDI and PROMIS PI. Correlation and regression analyses were performed. One hundred ninety-six patients met inclusion criteria. The average age was 56.9±12.9 years. The mean NDI score was 68.6±38 and PROMIS PI was 60.9±7.3. The PROMIS PI was strongly correlated with the NDI ( r =0.76, P <0.001). Linear regression analysis revealed the following formula. We performed a regression analysis allowing for the conversion of PROMIS PI scores with NDI. In keeping with the previous studies, our analysis showed that PROMIS PI was most strongly correlated to NDI. A PROMIS PI score >66 was correlated to substantial disability (NDI=50), whereas a PROMIS PI score <59 was correlated to minimal relative impairment (NDI=28). These results provide important reference, as PROMIS reporting becomes more widespread in the literature.

Preoperative Patient Reported Outcomes Measurement Information System Scores Assist in Predicting Early Postoperative Success in Lumbar Discectomy.

Retrospective review of prospective data. Determine whether patient reported outcome (PRO) data collected prior to lumbar discectomy predicts achievement of a minimal important difference (MID) after surgery. Compare ability of PRO and clinical information to predict achievement of MID in short term follow-up after discectomy. We investigated the ability of patient reported outcomes measurement information system (PROMIS) and clinical factors at the preoperative time point to determine patients achieving MID after surgery. PROMIS physical function (PF), pain interference (PI), and depression (D) scores were assessed at evaluation and follow-up for consecutive visits between February, 2015 and September, 2017. Patients with preoperative scores within 30 days prior to surgery and with scores 40 days or more after surgery who completed all PROMIS domains were included yielding 78 patients. MIDs were calculated using a distribution-based method. A multivariate logistic regression model was created, and the ability to predict achieving MID for each of the PROMIS domains was assessed. Cut-off values and prognostic probabilities were determined for this model and models combining preoperative PROMIS with clinical data. Preoperative PROMIS scores modestly predict reaching MID after discectomy (areas under the curve [AUC] of 0.62, 0.68, and 0.76 for PF, PI, and D, respectively). Preoperative cut-off scores show patients who have PF and PI scores more than 2 standard deviations, and D more than 1.5 standard deviations worse-off than population mean are likely to achieve MID. The combination of PROMIS with clinical data was the most powerful predictor of reaching MID with AUCs of 0.87, 0.84, and 0.83 for PF, PI, and D. PROMIS scores before discectomy modestly predict improvement after surgery. Preoperative PROMIS combined with clinical factors was more predictive of achieving MID than either clinical factors or PROMIS alone. 3.

The Dutch–Flemish PROMIS Physical Function item bank exhibited strong psychometric properties in patients with chronic pain

ObjectiveThe objective of this study was to assess the psychometric properties of the Dutch–Flemish Patient-Reported Outcomes Measurement Information System (PROMIS) Physical Function item bank in Dutch patients with chronic pain. Study Design and SettingA bank of 121 items was administered to 1,247 Dutch patients with chronic pain. Unidimensionality was assessed by fitting a one-factor confirmatory factor analysis and evaluating resulting fit statistics. Items were calibrated with the graded response model and its fit was evaluated. Cross-cultural validity was assessed by testing items for differential item functioning (DIF) based on language (Dutch vs. English). Construct validity was evaluated by calculation correlations between scores on the Dutch–Flemish PROMIS Physical Function measure and scores on generic and disease-specific measures. ResultsResults supported the Dutch–Flemish PROMIS Physical Function item bank's unidimensionality (Comparative Fit Index = 0.976, Tucker Lewis Index = 0.976) and model fit. Item thresholds targeted a wide range of physical function construct (threshold-parameters range: −4.2 to 5.6). Cross-cultural validity was good as four items only showed DIF for language and their impact on item scores was minimal. Physical Function scores were strongly associated with scores on all other measures (all correlations ≤ −0.60 as expected). ConclusionThe Dutch–Flemish PROMIS Physical Function item bank exhibited good psychometric properties. Development of a computer adaptive test based on the large bank is warranted.

First use of patient reported outcomes measurement information system (PROMIS) measures in adults with neurofibromatosis.

The patient reported outcomes measurement information system (PROMIS) provides clinicians and researchers access to reliable, validated measures of physical, mental, and social well-being. The use of PROMIS can facilitate comparisons among clinical subpopulations and with the U.S. general population. We report on the first study using PROMIS measures in patients with neurofibromatosis (NF). Eighty-six adult patients (mean age = 44; 55% female; 87% white; 50% NF1, 41% NF2 and 9% schwannomatosis) completed a battery of PROMIS computerized adaptive tests (CATs). Across all PROMIS instruments, mean scores for each CAT were between 48.97 and 52.60, which is within ±0.5 SD of the U.S. general population norms. However, scores were distributed across a broad range for each PROMIS measure (±3 SDs). Clinically meaningful scores (defined >1 SD impairment) were observed in 20% (pain interference), 17% (pain behavior), 16% (physical function), 16% (anxiety), 16% (depression), 15% (satisfaction with social roles), 13% (fatigue), 6% (anger), and 5% (satisfaction with discretionary social activities) of the sample. All PROMIS measures were highly interrelated in bivariate analysis (P ≤ .001). There were no differences in PROMIS scores by disease type (NF1, NF2 and schwannomatosis), or self reported learning disabilities, or compared with the US population. Scores suggest a broad continuum of symptoms and functioning in patients with NF that is not affected by NF type, as well as interrelation among the physical and psychosocial domains as measured by PROMIS. PROMIS measures may be useful in clinical practice to monitor changes in symptoms and functioning over time, as well as in clinical trials to determine patient reported changes during drug and psychosocial clinical trials.

Caregiver Quality of Life Is Related to Severity of Otitis Media in Children.

Otitis media (OM) in children is the most frequent reason for physician visits in developed countries and burdens caregivers, society, and the child. Our objective was to describe the impact of OM severity on parent/caregiver quality of life (QoL). Multi-institutional prospective cross-sectional study. Otolaryngology, family, and pediatric practices. Children 6 to 24 months old with and without a primary diagnosis of recurrent OM and their caregivers. Physicians provided patient history, and parents/caregivers completed a Family Information Form, the PedsQL Family Impact survey, the Patient Reported Outcomes Measurement Information System (PROMIS) survey, and the OM 6-item severity survey (OM-6). A total of 2413 subjects were enrolled and data from 1208 patients and physician were analyzed. The average child age was 16 months, and 54% were male. The mean OM-6 score was 3.2. The mean PedsQL Family Impact score for parents was 66.9 from otolaryngology sites and 78.8 from pediatrics/family practice sites (P < .001). Higher (worse) OM-6 scores correlated significantly with worse PedsQL Family Impact scores (Pearson r = -0.512, P < .01). Similarly, increasing OM-6 scores strongly correlated with increased parental anxiety, depression, and fatigue, as well as decreased satisfaction (all P < .01). Worse PedsQL Family Impact and PROMIS scores were highly correlated with elevated OM-6 scores, suggesting that severity of childhood OM significantly affects parent/caregiver QoL. Understanding the impact of a child's illness on parent/caregiver QoL can help physicians counsel patients and families and provide better family-centered, compassionate care.
