Complications and healthcare utilization in commercially-insured osteoporotic vertebral compression fracture patients: a comparison of kyphoplasty versus propensity-matched controls.

ABSTRACT:

Background context

Osteoporotic vertebral fractures (OVFs) can lead to severe pain and reduced function and quality-of-life, but the strength of evidence for treatments remains low, particularly in younger populations.

Purpose

To determine whether patients with OVFs who received kyphoplasty had different patterns of healthcare utilization compared to propensity-matched patients who did not receive vertebral augmentation.

Design

Observational cohort study.

Patient sample

We identified patients with OVFs from 2007 to 2018 in the IBM MarketScan Commercial Claims and Encounters Databases who received kyphoplasty and compared them to propensity-matched controls who did not receive vertebral augmentation (either kyphoplasty or vertebroplasty).

Outcome measures

Major medical complications within 30 days, fills of opioids from 1-week through 1-month postaugmentation, and spine-related gross covered payments from 3-days postkyphoplasty through 1-year post-OVF.

Methods

We used logistic regression to obtain odds ratios (ORs) and 95% confidence intervals (95% CIs) to compare binary outcomes and median analysis to compare continuous outcomes.

Results

Of the 15,197 OVF patients identified, 1,969 (13%) received kyphoplasty and 1,928 (98%) of these were propensity matched to nonaugmented controls. We did not observe differences in the odds of major medical complications within 30 days (adjusted OR [95% CI]: 1.0 [0.6, 1.8]) but patients who received kyphoplasty were more likely to have filled opioid medications within 30 days (adjusted OR [95% CI]: 1.3 [1.1, 1.5]) and had greater spine-related gross covered payments (kyphoplasty median [95% CI]: $1,340 [$240, $4,850]; nonaugmented: $7,870 [$7,480, $8,270]; adjusted difference in medians [95% CI]: $260 [$190, $2,050]).

Conclusions

In this cohort of patients <65 years, receipt of kyphoplasty was associated with greater likelihood of opioid fills and somewhat greater spine-related gross covered payments, but no difference in major medical complications. In this retrospective study of administrative data, we did not detect advantages of treatment with kyphoplasty compared with nonaugmentation for any of our outcomes.

Project description:Osteoporosis vertebral compression fractures (OVCF) are common with the aging process. This study aimed to compare the effects of unilateral transverse process extrapedicular (UEPKP) and bilateral transpedicular percutaneous kyphoplasty (BTPKP) for patients with thoracolumbar OVCF. Data from 136 patients with OVCF treated with single-level PKP in our hospital between May 2019 and April 2021 were studied. Patients were grouped based on surgical procedure: there were 62 patients in the UEPKP group and 74 in the BTPKP group. All clinical and radiological data were collected from medical records. Clinical outcomes, including visual analog scale (VAS), Oswestry Disability Index (ODI), and Japanese Orthopaedic Association (JOA) scores of the lumbar spine, were evaluated preoperatively, postoperatively, and at the follow-up visit. The radiological evaluations (anterior vertebral height rate and local kyphosis angle) and complications were also collected. All patients had successfully improved after surgery. In the UEPKP group, patients showed a significantly shorter operating time and lower fluoroscopy frequency than patients in the BTPKP group (p < 0.05). However, a significantly better distribution score and cement volume were found in the BTPKP group (p < 0.05). The UEPKP group achieved a significantly better VAS score (0.6 ± 0.5 vs. 0.9 ± 0.8) and ODI (24.7 ± 3.1 vs. 27.5 ± 1.8) at the final follow-up visit than the BTPKP group (p < 0.05). The UEPKP group showed significantly worse radiological outcomes (anterior height rate and local kyphosis angle) at the 6- and 12-month follow-ups (p < 0.05). As for complications, the UEPKP group showed significantly fewer facet joint violations and intraspinal leakages (p < 0.05). UEPKP could be a safe and effective alternative procedure for patients with thoracolumbar osteoporotic vertebral compression fracture, which possesses an apparent advantage in reducing intraspinal leakage and facet joint violation over BTPKP.

Project description:Study designRetrospective.BackgroundSymptomatic bone cement displacement (BCD) is a rare complication following percutaneous kyphoplasty (PKP) interventions for osteoporotic vertebral compression fracture (OVCF). This study aimed to investigate the incidence and the outcomes of symptomatic BCD comprehensively and identify its risk factors.MethodsThe clinical data of patients treated with PKP for OVCF between January 2012 and December 2020 were extracted. Patients who developed BCD following PKP during follow-up were divided into the symptomatic and asymptomatic groups. Patients who did not develop BCD were assigned to the control group. Univariate and multiple logistic regression analyses were used to compare the three clinical groups' features to assess the independent risk factors for the symptomatic and asymptomatic groups.ResultsA total of 896 patients were enrolled. Twenty-one patients (2.3%) were identified as having symptomatic BCD following PKP for OVCF, and 35 (3.9%) developed asymptomatic BCD. Compared with the control group, the symptomatic and asymptomatic groups had a higher incidence of anterior leakage, intravertebral vacuum cleft (IVC) signs, and a lower cement distribution score. The symptomatic group had a lower relative cross-sectional area (rCSA) of the paraspinal muscle (PSM), higher PSM fatty degeneration, and higher kyphotic angle (at the last follow-up) than the asymptomatic and control groups. For outcomes, the symptomatic group had a higher VAS/ODI score and a higher incidence of new vertebral fractures compared with the asymptomatic and control groups. Anterior leakage (OR: 1.737, 95% CI: 1.215-3.300), the IVC sign (OR: 3.361, 95% CI: 1.605-13.036), the cement distribution score (OR: 0.476, 95% CI: 0.225-0.904), PSM rCSA (OR: 0.953, 95% CI: 0.917-0.992), and PSM fatty degeneration (OR: 1.061, 95% CI: 1.005-1.119) were identified as independent risk factors for the symptomatic group. Anterior leakage (OR: 1.839, 95% CI: 1.206-2.803), the IVC sign (OR: 2.936, 95% CI: 1.174-9.018), and cement distribution score (OR: 0.632, 95% CI: 0.295-0.858) were independent risk factors for the asymptomatic group.ConclusionThe incidence of symptomatic BCD is 2.3% in patients treated with PKP. Anterior leakage, the IVC sign, and the distribution score were independent risk factors for BCD, and paraspinal muscle degeneration was a specific risk factor for symptomatic BCD. Symptomatic BCD can lead to poor outcomes.
