Improving on National Quality Indicators of Breast Cancer Care in a Large Public Hospital as a Means to Decrease Disparities for African American Women

Background

In April 2007, the National Quality Forum (NQF) endorsed the first nationally recognized hospital-based performance measures for stage I, II, and III breast cancer. The purpose of this study was to document compliance with the 3 NQF breast quality indicators during 2 time intervals in a metropolitan public hospital.

Materials and Methods

Tumor registry and medical records were used to identify patient demographics and treatments before (2005–2006) and after (2008) implementations in 2007 as a result of the NQF audit. Program changes included: hiring a dedicated medical oncology nurse practitioner, requiring the radiation oncology case manager to attend weekly multidisciplinary conferences, educating Patient Navigators of the importance of multimodal care, and providing support groups for patients addressing importance of completion of all treatment options.

Results

A total of 213 female patients were diagnosed with and treated for stage I, II, or III breast cancer in 2005–2006 and 2008. Of these, 189 (89%) were African American (AA) women. Also, 70 patients of 86 (81.3%) received radiation therapy, 60 of 77 (77.9%) received or were considered for adjuvant chemotherapy, and 124 of 144 (86.1%) for hormonal therapy according to NQF indicators. After 2007, patients receiving radiation therapy increased from 75.8 to 95.8%. Patients receiving or considered for adjuvant chemotherapy or hormonal therapy increased from 73.7 to 93.7% and from 84.1 to 90.0%, respectively.

Conclusions

NQF breast cancer indicators provided a mechanism to improve compliance of multimodal treatment in our center. Raising awareness of these indicators in the multidisciplinary conference, hiring dedicated personnel, and educating patients has led to major improvements in breast cancer care.     

Multimodal analgesic approach incorporating paravertebral blocks for open radical retropubic prostatectomy: a randomized double-blind placebo-controlled study

Introduction

Perioperative pain management influences both the quality as well as the speed of recovery following surgery.

Methods

This was a randomized double-blind placebo-controlled study designed to assess the effectiveness of a multimodal analgesic approach (MMA) vs patient-controlled analgesia (PCA) alone in patients undergoing open prostatectomy. Prior to surgery, paravertebral blocks (PVBs) were performed with either 0.5% ropivacaine in the MMA group or saline in the PCA group. Patients in the MMA group also received celecoxib (400 mg po prior to surgery and 200 mg po bid for seven days following surgery) and ketamine 10 mg iv. Following surgery, every patient had free access to morphine PCA. A pain numerical rating scale (NRS) at 24 hr was chosen as the primary endpoint. Secondary endpoints included morphine consumption at 24 hr and SF-36 (36-Item Short-Form Health Survey) scores from two weeks to 24 weeks following surgery.

Results

The primary endpoint, average pain NRS at 24 hr, was 2.6 in the MMA group compared with 3.9 in the PCA group (difference = ?1.6, 95% confidence interval [CI]: ?2.3 to ?0.4; P = 0.01). The average morphine consumption at 24 hr was 4.8 mg in the MMA group compared with 10.5 mg in the PCA group (difference = ?5.7, 95% CI: ?13.0 to 0.5; P = 0.01). Higher SF-36 scores at two, four, eight, and 12 weeks were observed in the MMA group compared with the PCA group, but no statistically significant (P < 0.05) between-group difference was found after Bonferroni correction of comparisons conducted repeatedly over time. Postoperative adverse effects included low episodes of postoperative nausea and vomiting, bladder spasms, constipation, and pruritus.

Conclusion

This study demonstrates that PVBs combined with celecoxib and ketamine provide better immediate postoperative pain control and facilitate earlier functional recovery in patients undergoing an open radical prostatectomy when compared with PCA alone.     

Fracture risk with pressurized-spray cryosurgery

Forty-two patients treated with curettage, burring, direct pressurized cryotherapy, and bone grafting or cementation were retrospectively reviewed. There were no pathologic fractures in this study group, compared with a 17% fracture rate in recent studies using the "direct pour" technique. Direct pressurized cryotherapy was used in 3 separate freezing cycles in each case. This approach may significantly reduce the risk for fracture compared with historical controls using the direct-pour technique.     

Round ligament cyst, a rare condition simulating inguinal hernia. Case report

Cysts of the inguinal cord are disorders that simulate inguinal hernias and manifest as inguinal masses and, in some cases, are accompanied by pain that can simulate a complicated inguinal hernia. We report the third case of a round ligament cyst in a 21-year-old female with a mass in the right inguinal area with intermittent pain. The patient was subjected to surgical exploration of the right inguinal area where a round ligament cyst was found. The ligament was resected and reported as a serous cyst. The patient's outcome was excellent and she was discharged 24 h after surgery. She has been followed up for 3 months without recurrence. Round ligament cysts are very rare disorders, and the diagnosis is perioperative. Resection of the round ligament causes complete symptom relief, and every case requires inguinal hernioraphy.     

Should patients undergoing coronary artery bypass grafting with mild to moderate ischaemic mitral regurgitation also undergo mitral valve repair or replacement?

A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was whether mitral valve repair at the time of coronary artery bypass grafting (CABG) in patients with coronary artery disease and mild to moderate mitral insufficiency improves short and long-term outcome. Altogether 465 papers were found using the reported search, of which 16 presented the best evidence to answer the clinical question. The author, journal, date and country of publication, patient group studied, study type, relevant outcomes, results, and study weaknesses of these papers are tabulated. We conclude that there is good evidence to suggest that moderate mitral regurgitation in patients undergoing isolated CABG adversely affects survival and mitral regurgitation does not reliably improve after CABG alone. Unfortunately, the evidence to support mitral valve repair at the time of CABG to improve long-term survival is still weak. On balance, patients with moderate ischaemic mitral regurgitation having CABG should have mitral repair at the same time, although the evidence to support this is weaker than one might like.     

An optimal regulator for linear systems with multiple state and input delays

This paper presents an optimal regulator for a linear system with multiple state and input delays and a quadratic criterion. The optimal regulator equations are obtained reducing the original problem to the linear‐quadratic regulator design for a system without delays. Performance of the obtained optimal regulator is verified in the illustrative example against the best linear regulators available for the linear system without delays and for two rational approximations of the original time‐delay system. Simulation graphs demonstrating better performance of the obtained optimal regulator with respect to the criterion value are included. Copyright © 2006 John Wiley & Sons, Ltd.     

Larger urethral catheter size leads to fossa navicularis stricture formation in robotic radical prostatectomy

Fossa navicularis strictures following radical prostatectomy are reported infrequently. We recently experienced a series of fossa strictures following robotic-assisted laparoscopic prostatectomy (RLP). We describe herein our experience to prevent fossa strictures and to determine its etiologic factors. From June 2002 to May 2006, 424 patients underwent robotic-assisted laparoscopic prostatectomy with the da Vinci surgical system. Fossa strictures were diagnosed based on the acute onset of obstructive voiding symptoms and bougie calibration. During our series, we switched from the intra-operative use of an 18 French (F) catheter to that of a 22 F one to avoid inadvertent stapling of the urethra when dividing the dorsal venous complex. After we observed a high incidence of fossa strictures, we reverted back to 18 F catheters during surgery. All patients had an 18 F catheter indwelling for 1 week after surgery. Parameters were evaluated using Fisher’s exact test and Student’s t-test for means. The 18 F catheter group of patients (n = 293) developed one fossa stricture, whereas the 22 F catheter group (n = 131) developed nine fossa strictures (P < 0.01). The fossa stricture rate in the 18 F group was 0.3% versus 6.9% in the 22 F group. The two groups had no differences in age, body mass index, cardiovascular disease, American Urological Association symptom score, urinary bother score, preoperative prostate-specific antigen, operative time, estimated blood loss, cautery use, prostate size, or catheterization time. Based on these results, a larger urethral catheter size – 20 F versus 18 F – during the intra-operative dissection would appear to increase the risk for fossa stricture by more than 20-fold.

Burkholderia gladioli: five year experience in a cystic fibrosis and lung transplantation center.

BACKGROUND: The impact of infection with Burkholderia gladioli in cystic fibrosis, other chronic airway diseases and immunosuppressed patients is unknown. METHODS: A six-year retrospective review of all patients with B. gladioli infection was performed in a tertiary referral center with cystic fibrosis and lung transplantation programs. In addition, a targeted survey of all 251 lung transplant recipients was performed. Available B. gladioli isolates were analyzed via pulsed field gel electrophoresis. RESULTS: Thirty-five patients were culture positive for B. gladioli, including 33 CF patients. No bacteremia was identified. Isolates were available in 18 patients and all were genetically distinct. Two-thirds of these isolates were susceptible to usual anti-pseudomonal antibiotics. After acquisition, only 40% of CF patients were chronically infected (> or =2 positive cultures separated by at least 6 months). Chronic infection was associated with resistance to > or =2 antibiotic groups on initial culture and failure of eradication after antibiotic therapy. The impact of acquisition of B. gladioli infection in chronic infection was variable. Three CF patients with chronic infection underwent lung transplantation. One post-transplant patient developed a B. gladioli mediastinal abscess, which was treated successfully. CONCLUSIONS: The majority of patients' culture positive for B. gladioli at our center have CF. B. gladioli infection is often transient and is compatible with satisfactory post-lung transplantation outcomes.     

The degree of bone mineralization is maintained with single intravenous bisphosphonates in aged estrogen-deficient rats and is a strong predictor of bone strength

The treatment of osteoporotic women with bisphosphonates significantly reduces the incidence of bone fractures to a degree greater than can be explained by an increase in bone mineral density. In this study, 18-month Fischer 344 rats were ovariectomized and treated with a single dose of risedronate (intravenous, iv, 500 microg), zoledronic acid (iv, 100 microg) or continuous raloxifene (2 mg/kg, po, 3x/week). High resolution microCT was used to measure lumbar vertebral bone microarchitecture, the degree of bone mineralization (DBM) and the distribution of mineral. Small angle X-ray scattering was used to investigate mineral crystallinity. We found prolonged estrogen deficiency, reduced trabecular bone volume, and increased micro architecture bone compression strength lowered the degree of mineralization. Treatment with resorptive agents (bisphosphonates>raloxifene) prevented the loss of mineralization, trabecular bone volume and bone compression strength. Crystal size was not changed with OVX or with anti-resorptive treatments. In conclusion, in the aged estrogen-deficient rat model, single intravenous doses of two bisphosphonates were effective in maintaining the compressive bone strength for 180 days by reducing bone turnover, and maintaining the DBM to a greater degree than with raloxifene.     

Examining the association between media coverage of organ donation and organ transplantation rates

Research addressing the organ shortage in the USA has examined multiple factors influencing one's decision to become an organ donor. One of these research lines addresses media coverage of organ donation. The present investigation seeks to advance this research line by examining the association between organ donation media coverage and organ transplantation rates. A content analysis spanning January 1990 to December 2005 of three television networks reveals an overall positive association between coverage and transplantation rates. The implications of our findings are discussed along with recommendations for practitioners and advocates alike.
