Feasibility of Capturing Cancer Treatment Data in the Utah All-Payer Claims Database.

PURPOSE: Incompleteness of treatment data is a recognized limitation of cancer registry data. An all-payer claims database (APCD) is a tool that states use to capture health care information across systems and payer. We linked the Utah Cancer Registry (UCR) records to Utah's statewide APCD and evaluated how this linkage led to improvements in the capture of cancer treatment information. METHODS: We linked cancers diagnosed and reported to the UCR with Utah APCD claims for the calendar years 2013 and 2014 using LinkPlus Software. For patients with breast or colorectal cancers, manual abstraction was completed to provide a gold-standard comparison for the treatment data obtained from the claims. RESULTS: Among 10,759 reportable cancer occurrences linked to the APCD, the claims identified additional patients with cancer who received therapies that had been unknown to the registry, increasing the proportion treated with chemotherapy from 23.7% to 27.6%, hormone therapy from 14.1% to 18.8%, immunotherapy from 4.3% to 13.2%, and radiation therapy from 24.9% to 27.5%. The APCD increased the sensitivity of treatment variables compared with the abstraction gold standard. Notably, sensitivity of hormonal therapy for breast cancer increased from 78.6% to 95.2% when augmented with APCD claims data. However, the APCD alone did not achieve as high specificity for treatment data as did the data collected through traditional registry methods. CONCLUSIONS: This is the first study, to our knowledge, showing that linking cancer registry data with a statewide claims database that covers multiple insurance companies improves cancer treatment data collection. Linking of cancer registry and APCD data can improve comprehensiveness of cancer registry treatment data.

Linkage between Utah All Payers Claims Database and Central Cancer Registry.

OBJECTIVE: To evaluate the linkage of claims from the Utah All Payers Claims Database (APCD) and Utah Cancer Registry (UCR). DATA SOURCES: Secondary data from 2013 and 2014 Utah APCD and 2013 UCR cases. STUDY DESIGN: This is a descriptive analysis of the quality of linkage between APCD claims data and cancer registry cases. DATA COLLECTION/EXTRACTION METHODS: We used the LinkPlus software to link Utah APCD and UCR data. PRINCIPAL FINDINGS: We were able to link 82.4 percent (9441/11 453) of the UCR reportable cancer cases with APCD claims. Of those linked, 66 percent were perfect matches. CONCLUSIONS: The quality of identifiers is high, evidence that claims data can potentially supplement cancer registry data for use in research.

Associations Between Physical Therapy Continuity of Care and Health Care Utilization and Costs in Patients With Low Back Pain: A Retrospective Cohort Study.

Background: Patients who consult a physical therapist for low back pain (LBP) may receive initial and subsequent management from different therapists. The impact that physical therapy provider continuity has on health care use in patients with LBP is insufficiently studied. Objective: The objective of this study was to examine the impact of continuity of the physical therapy provider on health care use and costs in patients with LBP referred from primary care. Design: The study design included a retrospective analysis of claims data. Methods: Data from an all-payer claims database were examined. Logistic regression was used to evaluate the association between physical therapy provider continuity and health care use during the 1-year period following a visit with a primary care provider for LBP. Results: Patients who experienced greater physical therapy provider continuity had a decreased likelihood of receiving lumbar surgery. They also paid less (mean = ${\$}$1737 [95% confidence interval, ${\$}$1602-${\$}$1871]) than those who experienced less physical therapy provider continuity (mean = ${\$}$2577 [95% confidence interval, ${\$}$2008-${\$}$3145]). Limitations: The degree of causality between any predictor and outcome variables cannot be determined due to the observational nature of the study. Conclusions: Greater continuity of the physical therapy provider appears to be associated with a decreased likelihood of surgical treatment for LBP and lower health care costs related to LBP.

Guided Tissue Regeneration Involving Piercing-Induced Lingual Recession: A Case Report.

Recession on the lingual aspect of mandibular incisors may occur in patients with history of tongue piercing and other factitious traumatic habits. Treatment of these areas is challenging due to the site-specific anatomical features of the region. This case report presents a novel approach for a specific type of mandibular lingual defect caused by tongue piercing. A nonresorbable titanium-reinforced barrier membrane combined with an allograft and enamel matrix derivatives was used to promote regeneration of periodontal attachment. Reentry surgery for membrane removal was performed at 8 weeks. The time from initial surgery to final follow-up was 18 months.

Prospective Clinical and Radiographic Study of Alveolar Ridge Preservation Combining Freeze-Dried Bone Allograft With Two Xenogeneic Collagen Matrices.

BACKGROUND: Tooth extractions are followed by significant dimensional changes in the alveolar crest that may preclude implant placement. This randomized, controlled, prospective compares the preservation of soft and hard tissue dimensional changes after alveolar ridge preservation (ARP) using two membranes consisting of collagen matrix (CM) or extracellular matrix (ECM) as barriers over freeze-dried bone allograft (FDBA). METHODS: Standardized clinical and radiographic measurements of soft and hard tissues were recorded by means of a stent before and 4 months after ARP. The surgery entailed sulcular incisions with minimal flap elevation and repositioning without advancement. RESULTS: Of 11 patients in the CM group and 12 in the ECM group who completed the study, gingival thickness (GT) increased from 0.1 to 0.2 mm for both groups along with a 0.5-mm decrease in the width of keratinized tissue after healing. Reductions in ridge width were most pronounced on the coronal aspect, 1.8 mm for CM and 2.0 mm for ECM, whereas vertical reduction was most pronounced on the buccal aspect, 0.7 to 1.0 mm. Differences between groups were not statistically significant. However, significant correlation for changes in GT (P = 0.001) and crestal bone width (P = 0.002) with preoperative buccal plate thickness (BPT) was observed. CONCLUSIONS: Both xenogeneic collagen matrices combined with FDBA were effective in maintaining soft tissues and minimizing ridge resorption in all dimensions after ARP. BPT was an important determinant for amount of change in crestal GT and ridge width.

Early bone healing around 2 different experimental, HA grit-blasted, and dual acid-etched titanium implant surfaces. A pilot study in rabbits.

PURPOSE: To compare early bone healing around different experimental titanium implant surfaces and to evaluate the role of a calcium phosphate-coated implant surface because it relates to bone-implant contact (BIC). METHODS: An experimental hydroxyapatite (HA) grit-blasted and dual acid-etched titanium surface (BAE-1) was compared to an experimental HA grit-blasted and dual acid-etched surface treated with nanometer-scale crystals of HA (BAE-2). Both experimental implant surfaces were implanted onto the tibias of 4 New Zealand white rabbits. The animals were killed at 1,6, 21, and 90 days after the implant surgery. Descriptive histology was performed at the healing responses of both implant surfaces. Quantitative morphology assessment provided measurements of BIC, number of bone multicellular units (BMUs), average penetration of BMUs, and maximum penetration of BMUs that were manually made using imaging computer software. RESULT: The overall BIC for the BAE-2 implant was higher than that for the BAE-1 implant at 21 days of healing. However, there was no significant difference at 90 days of healing. CONCLUSION: It is concluded from this animal pilot study that the bioactive BAE-2 implant surface provided a better BIC with healthy bone remodeling at 21 days of healing.
