The effect of telemonitoring at home on quality of life and self-care behaviors of patients with heart failure.

Heart failure (HF) is a costly chronic disease that affects 5.7 million people in the United States. Home healthcare agencies are implementing initiatives to reduce hospitalizations and manage HF patients at home. In this study, telemonitoring improved patients' perception of their quality of life and assisted them to sustain critical self-care behaviors. Patients who were monitored had fewer hospitalizations but telemonitoring was not statistically significant in lowering hospitalizations.

Endometrial cancer surgery costs: robot vs laparoscopy.

STUDY OBJECTIVE: To compare surgical costs for endometrial cancer staging between robotic-assisted and traditional laparoscopic methods. DESIGN: Retrospective chart review from November 2005 to July 2006 (Canadian Task Force classification II-3). SETTING: Non-university-affiliated teaching hospital. PATIENTS: Thirty-three women with diagnosed endometrial cancer undergoing hysterectomy, bilateral salpingo-oophorectomy, and pelvic and paraaortic lymph node resection. INTERVENTIONS: Patients underwent either robotic or traditional laparoscopic surgery without randomization. MEASUREMENTS AND MAIN RESULTS: Hospital cost data were obtained for operating room time, instrument use, and disposable items from hospital billing records and provided by the finance department. Separate overall hospital stay costs were also obtained. Mean operative costs were higher for robotic procedures ($3323 vs $2029; p<.001), due in part to longer operating room time ($1549 vs $1335; p=.03). The more significant cost difference was due to disposable instrumentation ($1755 vs $672; p<.001). Total hospital costs were also higher for robotic-assisted procedures ($5084 vs $ 3615; p=.002). CONCLUSION: Robotic surgery costs were significantly higher than traditional laparoscopy costs for staging of endometrial cancer in this small cohort of patients.

Is there a role for MRI in the preoperative assessment of patients with DCIS?

BACKGROUND: Breast magnetic resonance imaging (MRI) is used to identify residual and additional disease in patients with invasive carcinoma. The use of MRI in assessing extent of disease for ductal carcinoma in situ (DCIS) is less well defined. This study assessed the value of MRI in the preoperative evaluation of DCIS. MATERIALS AND METHODS: We identified 98 patients with DCIS in 2007. Of these, 63 underwent stereotactic biopsy, followed by MRI. There were 35 who underwent stereotactic biopsy alone. Concordance between MRI and histopathology was defined as the presence or absence of residual disease. RESULTS: There was no significant difference in mastectomy rates between the MRI and non-MRI group (20.3% vs 25.7%, P = .62). In patients undergoing breast-conserving surgery (BCS), there were fewer positive margins in the MRI versus the non-MRI group (21.2% vs 30.8%, P = .41). Of the 64 cases that underwent preoperative MRI, 43 (67.2%) were concordant. Also, 15 of 43 cases (34.8%) had MRI results that accurately predicted pathologic size. In 28 of 43 patients (65.2%), MRI overestimated disease in 20, by a mean of 1.97 cm. In patients with MRI tumor size >2 cm, MRI overestimated disease by a mean of 3.17 cm. Of the 64 cases, 21 (32.8%) were discordant. Also, 10 of 21 (47.6%) had a positive MRI and no residual disease on histopathology, and 11 of 21 (52.3%) had negative MRI and residual disease on pathology. CONCLUSIONS: MRI does not accurately predict extent of disease in patients with extensive DCIS. In patients with MRI tumor size < or = 2 cm, MRI may assist in surgical planning. MRI results in patients with DCIS should be interpreted with caution; decision for mastectomy should not be made on MRI findings alone.
