Objective

Phlebolymphedema (chronic venous insufficiency-related lymphedema) is a common and costly condition. Nevertheless, there is a dearth of evidence comparing phlebolymphedema therapeutic interventions. This study sought to examine the medical resource utilization and phlebolymphedema-related cost associated with Flexitouch (FLX; Tactile Medical, Minneapolis, Minn) advanced pneumatic compression devices (APCDs) relative to conservative therapy (CONS) alone, simple pneumatic compression devices (SPCDs), and other APCDs in a representative U.S. population of phlebolymphedema patients.

Methods

This was a longitudinal matched case-control analysis of deidentified private insurance claims. The study used administrative claims data from Blue Health Intelligence for the complete years 2012 through 2016. Patients were continuously enrolled for at least 18 months, diagnosed with phlebolymphedema, and received at least one claim for CONS either alone or in addition to pneumatic compression (SPCDs or APCDs). The main outcomes included direct phlebolymphedema- and sequelae-related medical resource utilization and costs.

Results

After case matching, the study included 86 patients on CONS (87 on FLX), 34 on SPCDs (23 on FLX), and 69 on other APCDs (67 on FLX). Compared with CONS, FLX was associated with 69% lower per patient per year total phlebolymphedema- and sequelae-related costs net of any pneumatic compression device-related costs ($3839 vs $12,253; P = .001). This was driven by 59% fewer mean annual hospitalizations (0.13 vs 0.32; P < .001) corresponding to 82% lower inpatient costs and 55% lower outpatient hospital costs. FLX was also associated with 52% lower outpatient physical therapy and occupational therapy costs and 56% lower other outpatient-related costs. Compared with SPCDs, FLX was associated with 85% lower total costs ($1153 vs $7449; P = .008) driven by 93% lower inpatient costs ($297 vs $4215; P = .002), 84% lower outpatient hospital costs ($368 vs $2347; P = .020), and 85% lower other outpatient-related costs ($353 vs $2313; P = .023). Compared with APCDs, FLX was associated with 53% lower total costs ($3973 vs $8436; P = .032) because of lower outpatient costs and lower rates of cellulitis (22.4% vs 44.9% of patients; P = .02).

Conclusions

This analysis indicates significant benefits attributable to FLX compared with alternative compression therapies that can help reduce the notable economic burden of phlebolymphedema.  相似文献

The CDKL5 disorder is characterized by early onset epilepsy, stereotypical hand movement, absent speech and severe hypotonia. Herein, we report epileptic encephalopathy with continuous spike-and-wave during sleep (CSWS) in apatient with CDKL5 disorder. She admitted with complaints of frequently recurring generalized tonic and myoclonic seizures. The diagnoses were confirmed by de novo CDKL5 mutation, c.197_198delCT (p.L67QfsX23). Interictal EEG revealed generalized spike and slow-wave activity, occurring intermittently in wakefulness but present for at least 85% of non-REM sleep, consistent with the diagnosis of CSWS. To our knowledge, this is the first report of CSWS associated with CDKL5 disorder.  相似文献

Identifying risk factors for mortality is crucial in the management of diabetic foot syndrome. We aimed to evaluate risk factors for mortality in patients with diabetic foot infection (DFI). A retrospective chart review was conducted on 401 patients from 2010 through 2019. Our primary endpoint was in‐hospital mortality. Patients were divided into two groups according to the outcome (survival or death). Clinical data were compared between the two groups statistically. A total of 401 patients were enrolled in the study, 280 (69.8%) of them were male and the mean age was 59.6 ± 11.1 years. The mean follow‐up period was 23.7 ± 22.9 months. In‐hospital mortality rate was 3%. Univariate analysis indicated that ischaemic wound (P = .023), hindfoot infection (P = .038), whole foot infection (P = .010), peripheral arterial disease (P = .024), high leucocyte levels (>12 040 K/μL) (P = .001), high thrombocyte levels (>378 000 K/μL) (P < 0.001), high C‐reactive protein levels (>8.81 mg/dL) (P = .022), and polymicrobial growth in deep tissue culture (P = .041) were significant parameters in predicting mortality. In multivariate analysis, peripheral arterial disease (odds ratio [OR]: 13.430, 95% confidence interval [Cl]: 1.129‐59.692; P = .040), high thrombocyte levels (OR: 1.000, 95% Cl: 1.000‐1.000; P = .022), and polymicrobial growth in deep tissue culture (OR: 7.790, 95% Cl: 1.592‐38.118; P = .011) were independent risk factors for mortality. In conclusion, peripheral arterial disease, high thrombocyte levels, and polymicrobial growth in deep tissue culture were independent risk factors for mortality in DFI.  相似文献
