Cancer pain: a review of epidemiology, clinical quality and value impact.

Cancer-related pain, reported by more than 70% of patients, is one of the most common and troublesome symptoms affecting patients with cancer. Despite the availability of effective treatments, cancer-related pain may be inadequately controlled in up to 50% of patients. With the growing focus on 'value' (healthcare outcomes achieved per dollar spent) in healthcare, the management of cancer-related pain has assumed novel significance in recent years. Data from initiatives that assess the quality of pain management in clinical practice have shown that effective management of cancer-related pain improves patient-perceived value of cancer treatment. As a result, assessment and effective management of cancer-related pain are now recognized as important measures of value in cancer care.

Celiac plexus neurolysis for abdominal cancers: going beyond pancreatic cancer pain.

INTRODUCTION: Celiac plexus neurolysis (CPN) has been verified for mitigating pancreatic cancer pain. However, information regarding CPN's use beyond this remains limited. OBJECTIVES: Identify which cancers benefit from CPN, which symptoms improve, and when symptoms improve. METHODS: Retrospective analysis was conducted on 173 patients who received CPN for pain caused by various malignancies. Mean symptom changes on the MD Anderson Symptom Inventory (MDASI) from baseline to 2 weeks, 1 month, and 2 months after CPN were analyzed overall and then by cancer type: pancreatic (all stages and stages III-IV), hepatobiliary, and nonpancreatic, nonhepatobiliary gastrointestinal (NPNH-gastrointestinal). RESULTS: Eighty-two pancreatic, 43 NPNH-gastrointestinal, 14 hepatobiliary, and 34 patients with other cancers met inclusion criteria. Statistically significant changes included decrease in the pain score at 1 month by 1.01 points for all cancers, 1.65 points for all pancreatic cancers, and 1.88 points for late-stage pancreatic cancers. At 2 months, pain decreased by 1.50 points for all cancers, 1.68 points for all pancreatic cancers, 2.37 points for late-stage pancreatic cancers, and 1.50 points in NPNH-gastrointestinal cancers. At 2 months, quality of life improved by 1.07 points for all cancers and 1.53 points for all pancreatic cancers. Sleep improved at 2 months for all cancers by 0.73 points and 1.60 points in late-stage pancreatic cancers. At 2 months, pancreatic cancer patients improved in general activity by 0.93 points, walking by 1.00 points, and working by 1.12 points. CONCLUSION: Celiac plexus neurolysis can decrease cancer symptom burden beyond pain including quality of life and sleep for pancreatic and nonpancreatic cancers, as well as general activity for pancreatic cancers.

The Armstrong Institute Resident/Fellow Scholars: A Multispecialty Curriculum to Train Future Leaders in Patient Safety and Quality Improvement.

The objective was to determine if a year-long, multispecialty resident and fellow quality improvement (QI) curriculum is feasible and leads to improvements in QI beliefs and self-reported behaviors. The Armstrong Institute Resident/Fellow Scholars (AIRS) curriculum incorporated (a) a 2-day workshop in lean sigma methodology, (b) year-long interactive weekly small-group lectures, (c) mentored QI projects, and (d) practicum-based components to observe frontline QI efforts. Pre-post evaluation was performed with the Quality Improvement Knowledge Application Tool (QIKAT) and the Systems Thinking Scale (STS) using the Wilcoxon matched-pairs signed-rank test. Sixteen residents and fellows started the AIRS curriculum and 14 finished. Scholars' pre and post mean scores significantly improved: STS 3.06 pre versus 3.60 post (P < .01) and QIKAT 1.24 pre versus 2.46 post (P < .01). Most scholars (92%) agreed that skills learned in the curriculum will help in their future careers. A multispecialty QI curriculum for trainees is feasible and increases QI beliefs and self-reported behaviors.

Role of myeloid cell factor-1 (Mcl-1) in chronic lymphocytic leukemia.

The primary abnormality in chronic lymphocytic leukemia (CLL) is a defect in apoptosis, probably related to alterations in the expressions of Bcl-2 family members. In transgenic mice over expressing the anti-apoptotic Bcl-2 family member, myeloid cell factor-1 (Mcl-1), B cell lymphomas occur. Moreover, mice conditional for the loss of Mcl-1 display a profound reduction in B and T lymphocytes. This suggests that Mcl-1 is an essential survival factor in lymphocytes. In the present study, we have evaluated the role of Mcl-1 in CLL. Mcl-1 protein expression was measured by Western blot analysis in the CLL cells of 45 patients and correlated with clinical variables and survival. Mcl-1 levels were similar in 29 patients to normal B and T lymphocytes, were decreased in 8 patients and increased in 12 patients. An inverse correlation was found between Mcl-1 expression and Rai stage (P = 0.001). When assessed by flow cytometry, Mcl-1 expressions were normally distributed among CLL cells in individual patients and the mean levels correlated with those obtained by Western blotting. To evaluate the role of Mcl-1 in drug resistance, Mcl-1 levels were sequentially measured in the leukemic cells of 4 CLL patients during therapy with fludarabine (Flu). The Mcl-1 levels were found to increase in 2 patients while the peripheral blood lymphocyte counts dropped, suggesting that the residual drug-resistant cells had the highest Mcl-1 levels. Primary CLL cells were also treated with chlorambucil (CLB) or Flu in vitro and the Mcl-1 levels decreased correlating with the sensitivity of these cells to undergo apoptosis. Drug sensitivities of the CLL cells to CLB and Flu were also measured by MTT assay and the concentrations of drug required to decrease cell viability by 50% (IC50) varied from 1.9 to 9.27 microM for Flu (median, 9.4 microM) and 10 to 32.5 microM (median, 5.5 microM) for CLB. The sensitivities of the leukemic cells to CLB correlated inversely with Mcl-1 levels (P < 0.05). These results suggest that Mcl-1 may contribute to cell survival in CLL.

Sacroiliac joint pain: a comprehensive review of epidemiology, diagnosis and treatment.

Sacroiliac joint (SIJ) pain is an underappreciated source of mechanical low back pain, affecting between 15 and 30% of individuals with chronic, nonradicular pain. Predisposing factors for SIJ pain include true and apparent leg length discrepancy, older age, inflammatory arthritis, previous spine surgery, pregnancy and trauma. Compared with facet-mediated and discogenic low back pain, individuals with SIJ pain are more likely to report a specific inciting event, and experience unilateral pain below L5. Owing in part to its size and heterogeneity, the pain referral patterns of the SIJ are extremely variable. Although no single physical examination or historical feature can reliably identify a painful SIJ, studies suggest that a battery of three or more provocation tests can predict response to diagnostic blocks. Evidence supports both intra- and extra-articular causes for SIJ pain, with clinical studies demonstrating intermediate-term benefit for both intra- and extra-articular steroid injections. In those who fail to experience sustained relief from SIJ injections, radiofrequency denervation may provide significant relief lasting up to 1 year. This review covers all aspects of SIJ pain, with the treatment section being primarily focused on procedural interventions.

Positive recognition program increases compliance with medication reconciliation by resident physicians in an outpatient clinic.

The purpose of this study was to determine if well-understood, positive reinforcement performance improvement models can successfully improve compliance by resident physicians with medication reconciliation in an outpatient clinical setting. During the preintervention phase, 36 anesthesiology residents who rotate in an outpatient pain clinic were instructed in the medication reconciliation process. During the postintervention phase, instruction was given, and then improvement was recognized publicly. Data on physician compliance were collected monthly. The authors performed a secondary analysis of the audit database, which contained 1733 patient charts. The data were divided into preintervention and postintervention phases for comparison. A 4-fold increase in compliance was found. When logistic regression was used to adjust for adaptation of resident physicians over time and year, the odds of reconciling were 82% higher postintervention. By the consistent application of this effective tool, the authors have demonstrated that sustained performance of a tedious but important task can be achieved.

A Lean Six Sigma quality improvement project to increase discharge paperwork completeness for admission to a comprehensive integrated inpatient rehabilitation program.

Lean Six Sigma (LSS) process analysis can be used to increase completeness of discharge summary reports used as a critical communication tool when a patient transitions between levels of care. The authors used the LSS methodology as an intervention to improve systems process. Over the course of the project, 8 required elements were analyzed in the discharge paperwork. The authors analyzed the discharge paperwork of patients (42 patients preintervention and 143 patients postintervention) of a comprehensive integrated inpatient rehabilitation program (CIIRP). Prior to this LSS project, 61.8% of required discharge elements were present. The intervention improved the completeness to 94.2% of the required elements. The percentage of charts that were 100% complete increased from 11.9% to 67.8%. LSS is a well-established process improvement methodology that can be used to make significant improvements in complex health care workflow issues. Specifically, the completeness of discharge documentation required for transition of care to CIIRP can be improved.
