RESUMEN

PURPOSE: Acute myeloid leukemia (AML) is a hematologic malignancy characterized by a poor prognosis but also a paradoxical possibility of cure. This renders decision-making complex and imminent. Unfortunately, many patients with AML misestimate their prognosis and treatment risk. While decision aids can improve illness understanding and reduce decisional conflict, there are no validated decision aids for AML. We developed and tested a novel AML decision aid (NCT03442452). METHODS: Patients (n = 20) were recruited at Duke University from May 2018 to February 2019. Participants completed assessments of AML knowledge and decisional conflict, before and after using the electronic decision aid. The primary endpoint was feasibility (endpoint met if > 80% of study participants completed all study components). Secondary analyses of efficacy were conducted using paired t tests for dependent pre-/post-samples. RESULTS: The primary endpoint of feasibility was met (100% of participants completed all study components). Secondary analyses showed improved knowledge and reduced decisional conflict after using the decision aid. Knowledge scores improved from a mean of 11.8 (out of 18) correct items at baseline to 15.1 correct items after using the decision aid (mean difference 3.35; p < 0.0001). Decisional conflict scores reduced significantly from baseline to post-test as well (mean difference - 6.5; p = 0.02). CONCLUSION: These findings suggest that our AML decision aid is a useful tool to improve the patient experience and promote shared decision-making in AML. A randomized efficacy trial is planned.

RESUMEN

PURPOSE: Utilization of electronic patient-reported outcomes (ePROs) in the clinic can improve quality of life and prolong survival in cancer care. However, there remain unanswered questions regarding trends in missing data and the potential effect on real-time patient care. METHODS: This study utilized a prospectively collected dataset of ePROs from oncology clinics that administered the Patient Care Monitor 2.0 (PCM), a validated symptoms survey assessing 78 items for men, and 86 for women. We tabulated the frequency of missing items, by item and domain (emotional, functional and physical symptom-related), and examined these by age, gender, education, race and marital status. RESULTS: Within 20,986 encounters, there were responses to at least 1 PCM item from 6933 unique patients. The highest frequency of missing answers occurred for: "attend a paid job" (10.7%), "reduced sexual enjoyment" (3.8%), and "run" (3.7%). By domain, 12.3% of functional, 8.4% of physical symptom-related, and 1.6% of emotional constructs contained at least one missing item. For functional and physical symptom-related items, missingness was most common in patients >60 years old. CONCLUSION: The frequency of missingness was highest for functional items, like attending a paid job, suggesting that some respondents (e.g., retirees without a paid job) skipped questions that were less applicable to them. More universal issues for cancer patients, such as emotional well-being, had much lower frequencies of missingness. This suggests differential item completion that warrants further study to understand the inherent drivers. Identifying causes of missingness could improve the clinical utility of ePROs and highlight opportunities to personalize care.

RESUMEN

BACKGROUND: African-Americans (AA) are 3 times more likely to have small-vessel-type ischemic strokes (SVS) than Whites. Small vessel strokes are associated with cognitive impairment, a relationship incompletely explained by white matter hyperintensity (WMH) burden. We examined whether inflammatory/endothelial dysfunction biomarkers are associated with cognition after SVS in AAs. METHODS: Biomarkers were obtained in 24 subjects (median age 56.5 years, 54% women, median 12 years education). Cognition was assessed more than 6 weeks poststroke using the memory composite score (MCS), which was generated using recall from the Hopkins Verbal Learning Test-II and Brief Visuospatial Memory Test-Revised. A semi-automated, volumetric protocol was used to quantify WMH volume (WMHv) on clinical MRI scans. Potential biomarkers including vascular cell adhesion molecule-1 (VCAM-1), interleukin-1 receptor antagonist, interleukin-6, interleukin-8, interleukin-10, interferon gamma, and thrombin-antithrombin (TAT) were log-transformed and correlated with MCS with adjustment for potential confounders. RESULTS: Among serum biomarkers, only VCAM-1-correlated with poorer memory based on the MCS (r = -.659; P = .0006). VCAM-1 (r = .554; P = .005) and age (r = .479; P = .018) correlated with WMHv; VCAM-1 was independently associated with MCS after adjustment for WMHv, age, and education (P = .023). CONCLUSIONS: The findings of this exploratory analysis suggest that endothelial dysfunction and inflammation as reflected by VCAM-1 levels may play a role in poststroke cognitive impairment. Additional studies are needed to validate this observation and to evaluate this relationship in non-AAs and with other stroke types and compare this finding to cognitive impairment in nonstroke populations.

RESUMEN

PURPOSE: Pruritus is a common symptom in cutaneous malignancies, but its impact on patients with solid tumors is unclear. We explored the impact and management of pruritus in patients with solid tumors, using patient-reported outcomes (PRO) data from a real-world registry. METHODS: From 2006 to 2011, patients seen in the Duke Cancer Institute reported their symptoms via the Patient Care Monitor v2.0, a validated PRO tool that includes a 0-10-point question about pruritus severity. From > 25,000 encounters, 203 patients reported severe pruritus (> 6/10) on at least one visit and 506 total visits were abstracted where patients reported either moderate or severe pruritus (> 3/10). From this cohort, we abstracted demographics, diagnosis, stage, cancer therapy, anti-pruritic therapy, and clinicians' responses. RESULTS: Mean age was 59.8 (SD 13.3), 134 (66%) were female, 125 (62%) were Caucasian, and 65 (32%) were African American. Breast cancer was the most common tumor (36.5%), followed by lung cancer (23.2%). Mean pruritus severity score was 6.8 (SD 1.8) for patients on chemotherapy, 6.9 (SD 1.8) for patients on targeted therapy alone or in combination, and 7.1(SD 1.8) for patients off treatment. Overall, 67% of patients reported at least two episodes of moderate-severe pruritus (mean # of visits 4.2 (SD 2.7)). Despite frequent report of severe and persistent pruritus, this was mentioned in just 28% of clinician notes and an intervention was recommended/prescribed in only 7% of visits. CONCLUSIONS: Pruritus is an under-addressed symptom in patients with solid tumors. Additional research is needed to understand the burden of pruritus in affected populations.

RESUMEN

BACKGROUND/AIMS: Pain is a major concern of patients with advanced cancer and their caregivers. There is strong evidence that pain coping skills training interventions based on cognitive-behavioral principles can reduce pain severity and pain interference. However, few such interventions have been tested for patients with advanced cancer and their family caregivers. This study aims to test the efficacy of a caregiver-guided pain coping skills training protocol on patient and caregiver outcomes. METHODS: A total of 214 patients age ≥18 with Stage III-Stage IV cancer and moderate to severe pain, along with their family caregivers, are being identified and randomized with a 1:1 allocation to the caregiver-guided pain coping skills training intervention or enhanced treatment-as-usual. Dyads in both conditions receive educational resources on pain management, and the caregiver-guided pain coping skills training intervention includes three weekly 60-min sessions conducted with the patient-caregiver dyad via videoconference. Measures of caregiver outcomes (self-efficacy for helping the patient manage pain, caregiver strain, caregiving satisfaction, psychological distress) and patient outcomes (self-efficacy for pain management, pain intensity and interference, psychological distress) are collected at baseline and post-intervention. Caregiver outcomes are also collected 3 and 6 months following the patient's death. The study is enrolling patients from four tertiary care academic medical centers and one free-standing hospice and palliative care organization. The primary outcome is caregiver self-efficacy for helping the patient manage pain. RESULTS: This article describes challenges in the design and implementation of the CaringPals trial. Key issues for trial design include the identification and recruitment of patients with advanced cancer and pain, and the follow-up and collection of data from caregivers following the patient's death. CONCLUSION: The CaringPals trial addresses a gap in research in pain coping skills training interventions by addressing the unique needs of patients with advanced cancer and their caregivers. Findings from this study may lead to advances in the clinical care of patients with advanced cancer and pain, as well as a better understanding of the effects of training family caregivers to help patients cope with pain.

RESUMEN

BACKGROUND: Approximately 38% of patients with colorectal cancer will develop isolated liver metastases. Sidedness of colon tumor is identified in non-metastatic and unresected metastatic cancers as predictive of survival, yet its dedicated analysis in resected liver metastases is minimal. Our primary aim was to assess whether left-sided primary tumors improve prognosis in stage IV cancer patients undergoing curative-intent liver metastasectomy; it was hypothesized that it would. METHODS: This is a retrospective, observational cohort study from 1996 to 2016 in a single tertiary-care facility. Survival from diagnosis was calculated via Kaplan-Meier method and compared between the right and left sides via log-rank analysis. RESULTS: Median survival differs significantly between colorectal tumors of the right and left origins after hepatic metastasectomy in 612 patients. In patients with right-sided tumors, median survival from diagnosis was 4.5 years (IQR 4.1-5.3), and 6.3 years (IQR 5.6-6.9) in those with left tumors (HR 1.5, 95% CI 1.38-1.60, p < 0.001). CONCLUSION: As in studies on earlier-stage or unresected metastatic disease, tumor sidedness is an important prognostic factor in patient survival with liver metastasectomy. Clinical risk scores should include side of primary tumor. Further work is needed to determine the molecular basis for this difference.

RESUMEN

BACKGROUND Adoption of HIV pre-exposure prophylaxis (PrEP) remains limited among populations at greatest risk for HIV acquisition. This study aims to assess awareness of PrEP among individuals in Durham, North Carolina, which has one of the highest rates of HIV diagnoses in the state.METHOD In 2015-2016, we administered a survey including questions to assess PrEP awareness to individuals at multiple venues throughout Durham, North Carolina.RESULTS A total of 139 respondents were surveyed. The majority were male (66%) and black/African American (75%); 21% were Hispanic/Latino. There were an estimated 53 men who have sex with men (MSM), of which 18 (33%) were black MSM M 24 years of age. Overall, only 53/138 (38%) respondents were aware of PrEP. Awareness was reported among 33/52 (63%) MSM respondents, 29/46 (63%) black MSM, and 10/17 (59%) black MSM M 24 years of age. In multivariate analysis, non-heterosexual orientation, health-insured status, and prior HIV testing were significantly associated with PrEP awareness. Ninety-four (69%) of 137 respondents reported prior HIV testing.LIMITATIONS Limitations include non-random sampling and limited sample size. Further research needs to be done in other areas of North Carolina, and assessment of PrEP acceptability and uptake needs to be performed.CONCLUSION This study reveals low overall awareness of PrEP in Durham, North Carolina, indicating that expanded outreach is necessary to increase public awareness and encourage adoption of PrEP among all demographics at risk for HIV.

RESUMEN

Pre-exposure prophylaxis (PrEP) is an effective HIV prevention method, but many primary care physicians (PCPs) have not incorporated PrEP into practice. While PrEP may be a key strategy to reducing high HIV transmission rates in the southern US, knowledge about PrEP prescribing patterns among PCPs in this region is lacking. An online survey was sent to a large network of PCPs at an academic medical center in North Carolina in October 2015. The survey was repeated in September 2016, after an educational intervention that included on-site trainings at 14 PCP offices. Chi-square tests were used to compare PrEP prescribing patterns among providers. The initial survey was sent to 389 PCPs, with 115 (30%) responding. Of these, 78% reported seeing men who have sex with men (MSM). Only 17% had prescribed PrEP. The most frequently identified barrier was lack of knowledge (60%). When the survey was repeated after the educational initiative, 79 PCPs (20%) responded. Of these, 90% reported seeing MSM, and 35% had prescribed PrEP. PCPs who had attended a training were more likely to have prescribed PrEP (OR 4.84, CI 1.77-13.21). In conclusion, PrEP prescribing among PCPs in the southern US is low. A survey among PCPs identified lack of knowledge as a barrier to prescribing, motivating an institutional-wide educational campaign in response. Further efforts are needed to continue to raise awareness and educate PCPs in the South about PrEP.

RESUMEN

PURPOSE: Shared decision-making in acute myeloid leukemia (AML) requires understanding patients' longitudinal experiences of illness, but little is known about the impact of remission status on patient-reported outcomes (PROs). We aimed to explore the association between remission status and PROs 6-12 months following induction chemotherapy. METHODS: Forty-two patients completed three validated instruments characterizing symptom burden (Patient Care Monitor v2.0), distress (NCCN Distress Thermometer), and QOL (FACT-Leu), as part of a longitudinal observational study. We used regression models to explore the relationship between remission status and PROs, and explore differences by initial disease type (de novo versus secondary/relapsed AML). RESULTS: Those with secondary or relapsed AML at study onset had marked impairments in all measures compared to de novo AML patients. After 6 months, their mean distress score was 4.8 (> 4.0 warrants intervention), they reported a mean of 14.1 moderate/severe symptoms and had a mean QOL score of 113.6, compared to 1.0, 1.7, and 155.2, respectively, for those with de novo AML (p < .0001). Similarly, patients in relapse had a mean distress score of 5.3, a mean of 12.8 moderate/severe symptoms, and a mean QOL score of 113.4, compared to 1.8, 5.7, and 143.8, respectively, among those in remission (p < .005). These patterns persisted after adjusting for baseline differences (p < .0001). CONCLUSION: Remission is associated with markedly better patient well-being in AML. Patients with secondary or relapsed AML face more severe symptom burden, distress, and QOL issues after induction. Interventions are needed to improve AML patients' experiences of illness.

RESUMEN

OBJECTIVE: Predictive models are increasingly being used in clinical practice. The aim of the study was to develop a predictive model to identify patients with platinum-resistant ovarian cancer with a prognosis of less than 6 to 12 months who may benefit from immediate referral to hospice care. METHODS: A retrospective chart review identified patients with platinum-resistant epithelial ovarian cancer who were treated at our institution between 2000 and 2011. A predictive model for survival was constructed based on the time from development of platinum resistance to death. Multivariate logistic regression modeling was used to identify significant survival predictors and to develop a predictive model. The following variables were included: time from diagnosis to platinum resistance, initial stage, debulking status, number of relapses, comorbidity score, albumin, hemoglobin, CA-125 levels, liver/lung metastasis, and the presence of a significant clinical event (SCE). An SCE was defined as a malignant bowel obstruction, pleural effusion, or ascites occurring on or before the diagnosis of platinum resistance. RESULTS: One hundred sixty-four patients met inclusion criteria. In the regression analysis, only an SCE and the presence of liver or lung metastasis were associated with poorer short-term survival (P < 0.001). Nine percent of patients with an SCE or liver or lung metastasis survived 6 months or greater and 0% survived 12 months or greater, compared with 85% and 67% of patients without an SCE or liver or lung metastasis, respectively. CONCLUSIONS: Patients with platinum-resistant ovarian cancer who have experienced an SCE or liver or lung metastasis have a high risk of death within 6 months and should be considered for immediate referral to hospice care.

RESUMEN

This non-technical tutorial focus on two questions about the analysis of data from randomised trials. Which is the more appropriate analysis of data from a randomised trial - an unadjusted analysis or an adjusted one? When a result is not statistically significant is it nevertheless appropriate to comment on its direction?

RESUMEN

AIMS/HYPOTHESIS: Although the Diabetes Prevention Program (DPP) established lifestyle changes (diet, exercise and weight loss) as the 'gold standard' preventive therapy for diabetes, the relative contribution of exercise alone to the overall utility of the combined diet and exercise effect of DPP is unknown; furthermore, the optimal intensity of exercise for preventing progression to diabetes remains very controversial. To establish clinical efficacy, we undertook a study (2009 to 2013) to determine: how much of the effect on measures of glucose homeostasis of a 6 month programme modelled after the first 6 months of the DPP is due to exercise alone; whether moderate- or vigorous-intensity exercise is better for improving glucose homeostasis; and to what extent amount of exercise is a contributor to improving glucose control. The primary outcome was improvement in fasting plasma glucose, with improvement in plasma glucose AUC response to an OGTT as the major secondary outcome. METHODS: The trial was a parallel clinical trial. Sedentary, non-smokers who were 45-75 year old adults (n = 237) with elevated fasting glucose (5.28-6.94 mmol/l) but without cardiovascular disease, uncontrolled hypertension, or diabetes, from the Durham area, were studied at Duke University. They were randomised into one of four 6 month interventions: (1) low amount (42 kJ kg body weight(-1) week(-1) [KKW])/moderate intensity: equivalent of expending 42 KKW (e.g. walking ∼16 km [8.6 miles] per week) with moderate-intensity (50% [Formula: see text]) exercise; (2) high amount (67 KKW)/moderate intensity: equivalent of expending 67 KKW (∼22.3 km [13.8 miles] per week) with moderate-intensity exercise; (3) high amount (67 KKW)/vigorous intensity: equivalent to group 2, but with vigorous-intensity exercise (75% [Formula: see text]); and (4) diet + 42 KKW moderate intensity: same as group 1 but with diet and weight loss (7%) to mimic the first 6 months of the DPP. Computer-generated randomisation lists were provided by our statistician (G. P. Samsa). The randomisation list was maintained by L. H. Willis and C. A. Slentz with no knowledge of or input into the scheduling, whereas all scheduling was done by L. A. Bateman, with no knowledge of the randomisation list. Subjects were automatically assigned to the next group listed on the randomisation sheet (with no ability to manipulate the list order) on the day that they came in for the OGTT, by L. H. Willis. All plasma analysis was done blinded by the individuals doing the measurements (i.e. lipids, glucose, insulin). Subjects and research staff (other than individuals analysing the blood) were not blinded to the group assignments. RESULTS: Number randomised, completers and number analysed with complete OGTT data for each group were: low-amount/moderate-intensity (61, 43, 35); high-amount/moderate-intensity (61, 44, 40); high-amount/vigorous-intensity (61, 43, 38); diet/exercise (54, 45, 37), respectively. Only the diet and exercise group experienced a decrease in fasting glucose (p < 0.001). The means and 95% CIs for changes in fasting glucose (mmol/l) for each group were: high-amount/moderate-intensity -0.07 (-0.20, 0.06); high-amount/vigorous 0.06 (-0.07, 0.19); low-amount/moderate 0.05 (-0.05, 0.15); and diet/exercise -0.32 (-0.46, -0.18). The effects sizes for each group (in the same order) were: 0.17, 0.15, 0.18 and 0.71, respecively. For glucose tolerance (glucose AUC of OGTT), similar improvements were observed for the diet and exercise (8.2% improvement, effect size 0.73) and the 67 KKW moderate-intensity exercise (6.4% improvement, effect size 0.60) groups; moderate-intensity exercise was significantly more effective than the same amount of vigorous-intensity exercise (p < 0.0207). The equivalent amount of vigorous-intensity exercise alone did not significantly improve glucose tolerance (1.2% improvement, effect size 0.21). Changes in insulin AUC, fasting plasma glucose and insulin did not differ among the exercise groups and were numerically inferior to the diet and exercise group. CONCLUSIONS/INTERPRETATION: In the present clinical efficacy trial we found that a high amount of moderate-intensity exercise alone was very effective at improving oral glucose tolerance despite a relatively modest 2 kg change in body fat mass. These data, combined with numerous published observations of the strong independent relation between postprandial glucose concentrations and prediction of future diabetes, suggest that walking ∼18.2 km (22.3 km prescribed with 81.6% adherence in the 67 KKW moderate-intensity group) per week may be nearly as effective as a more intensive multicomponent approach involving diet, exercise and weight loss for preventing the progression to diabetes in prediabetic individuals. These findings have important implications for the choice of clinical intervention to prevent progression to type 2 diabetes for those at high risk. TRIAL REGISTRATION: ClinicalTrials.gov NCT00962962 FUNDING: The study was funded by National Institutes for Health National Institute of Diabetes and Digestive and Kidney Diseases (NIH-NDDK) (R01DK081559).

RESUMEN

BACKGROUND: Cancer patients may experience financial distress as a side effect of their care. Little is known about which patients are at greatest risk for altering their care or lifestyle due to treatment-related financial distress. METHODS: We conducted a cross-sectional survey study to determine which patients are at greatest risk for altering their care or lifestyle due to treatment-related financial distress. Eligible patients were adults receiving cancer treatment enrolled between June 2010 and May 2011. We grouped coping strategies as lifestyle altering or care altering. We assessed coping strategies and relationships between covariates using descriptive statistics and analysis of variance. RESULTS: Among 174 participants, 89% used at least one lifestyle-altering coping strategy, while 39% used a care-altering strategy. Care-altering coping strategies adopted by patients included the following: not filling a prescription (28%) and taking less medication than prescribed (23%). Lifestyle-altering strategies included the following: spending less on leisure activities (77%), spending less on basics like food and clothing (57%), borrowing money (54%), and spending savings (50%). Younger patients were more likely than older patients to use coping strategies (p < 0.001). Lower-income patients adopted care-altering strategies more than higher-income patients (p = 0.03). Participants with more education and shorter duration of chemotherapy used lifestyle-altering strategies more than their counterparts (both p < 0.05). CONCLUSIONS: As a means of coping with treatment-related financial distress, patients were more likely to use lifestyle-altering approaches, but more than one-third adopted potentially harmful care-altering strategies. Younger age, lower income, higher education, and shorter duration of chemotherapy were characteristics associated with greater use of coping strategies. Copyright © 2015 John Wiley & Sons, Ltd.

We searched MEDLINE, EMBASE and the Cochrane Controlled Trials Register to determine whether oxygen relieves dyspnoea in mildly or non-hypoxemic COPD and included 18 randomised controlled trials (431 participants) in the meta-analysis using Cochrane methodology. Oxygen therapy reduced dyspnoea when compared with medical air; standardised mean difference -0.37 (95% CI -0.50 to -0.24; I(2)=14%). In a priori subgroup and sensitivity analyses, dyspnoea was reduced by continuous oxygen during exertion but not short-burst oxygen therapy. Continuous exertional oxygen can relieve dyspnoea in mildly or non-hypoxemic COPD, but evidence from larger clinical trials is needed.

RESUMEN

PURPOSE: Women with early-stage breast cancer face the complex decision to undergo one of three equally effective oncologic surgical strategies: breast-conservation surgery with radiation (BCS), mastectomy, or mastectomy with breast reconstruction. With comparable oncologic outcomes and survival rates, evaluations of satisfaction with these procedures are needed to facilitate the decision-making process and to optimize long-term health. METHODS: Women recruited from the Army of Women with a history of breast cancer surgery took electronically administered surgery-specific surveys, including the BREAST-Q© and a background survey evaluating patient-, disease-, and procedure-specific factors. Descriptive statistics and regression analysis were used to evaluate the effect of procedure type on breast satisfaction scores. RESULTS: Overall, 7,619 women completed the questionnaires. Linear regression revealed that women who underwent abdominal flap, or buttock or thigh flap reconstruction reported the highest breast satisfaction score, scoring an average of 5.6 points and 14.4 points higher than BCS, respectively (p < 0.0001 and p = 0.027, respectively). No difference in satisfaction was observed in women who underwent latissimus dorsi flap reconstruction compared with those who underwent BCS. Women who underwent implant reconstruction reported scores 8.6 points lower than BCS (p < 0.0001). Those with mastectomies without reconstruction or complex surgical histories scored, on average, 10 points lower than BCS (p < 0.0001). CONCLUSION: Women who underwent autologous tissue reconstruction reported the highest breast satisfaction, while women undergoing mastectomy without reconstruction reported the lowest satisfaction. These findings emphasize the value of patient-reported outcome measures as an important guide to decision making in breast surgery and underscore the importance of multidisciplinary participation early in the surgical decision-making process.

RESUMEN

OBJECTIVE: Pillars4Life is an educational program that teaches coping skills to cancer patients in a virtual group setting; it was recently implemented at 17 hospitals across the USA. The cost-effective, scalable, and assessable Pillars4Life curriculum targets psychosocial resources (e.g., self-efficacy and coping skills) as a means to reduce symptoms (e.g., depression, anxiety, and posttraumatic stress) and enhance quality of life. METHODS: Cancer patients were recruited from hospitals that received the LIVESTRONG Community Impact Project Award to enroll in a pilot study of Pillars4Life. Consenting participants met with a certified instructor weekly for 10 weeks in a virtual environment; the manualized intervention trained participants in personal coping skills. Longitudinal assessments over 6 months were assessed using validated instruments to determine changes in Pillars4Life targeted resources and outcomes. Multiple linear regression models examined the relationship between changes in targeted resources and changes in outcome from baseline to 3 months post-intervention. RESULTS: Participants (n = 130) had the following characteristics: mean age of 56 ± 11 years, 87% women, 11% non-Caucasian, and 77% with college degree. At 3- and 6-month follow-up, mean scores improved on all key outcome measures such as depression (Patient Health Questionnaire), anxiety (Generalized Anxiety Disorder), posttraumatic stress (Posttraumatic Stress Disorder Checklist), fatigue (Functional Assessment of Chronic Illness Therapy-Fatigue), and well-being (Functional Assessment of Cancer Therapy-General) from baseline (all p < 0.01); results were most pronounced among participants who reported ≥4/10 on the Distress Thermometer at baseline (all p < 0.001). Changes in each targeted resource were associated with 3-month improvements in at least one outcome. CONCLUSIONS: Participation in the Pillars4Life program was associated with statistically and clinically significant improvements in scores on pre-specified outcomes and targeted resources.

RESUMEN

PURPOSE: Patients with advanced non-small cell lung cancer (aNSCLC) face a significant symptom burden. Little is known about the frequency and severity of symptoms over time, so we longitudinally characterized patients' symptoms using the Patient Care Monitor (PCM) version 2.0, an electronic symptom-assessment tool. METHODS: Ninety-seven patients with aNSCLC completed the PCM at up to four clinic visits. We analyzed symptom data by incidence, severity, type (functional vs. nonfunctional), proximity to death, and cancer anorexia-cachexia syndrome status (CACS). RESULTS: Functional concerns predominated, even in the non-CACS group. Average severity among the top 5 symptoms was worse for functional than nonfunctional items (mean difference 0.62, 95% CI 0.22-1.01, P = 0.003). Severe dyspnea and fatigue were the most prevalent nonfunctional symptoms; moderate/severe dyspnea was reported by at least 29% of patients, and fatigue by over 50%. Depression was reported infrequently, with over half of patients at each visit reporting "none"; moderate or severe depression was reported in only 2.5-9.3 and 3.4-6.2% of patients, respectively. The average number of moderate/severe symptoms increased with proximity to death; 84% reported moderate/severe fatigue in the last 3 months of life, compared to 48% at ≥ 12 months from death (P = 0.007). CONCLUSIONS: Patients with aNSCLC face a significant symptom burden, which increases with proximity to death. Symptom type and severity vary by proximity to death, but even patients without overt CACS report significant functional symptoms throughout. We recommend an individualized approach to palliative symptom intervention in advanced lung cancer, based on detailed symptom assessment and tracking.

RESUMEN

BACKGROUND: Health care-related costs and satisfaction are compelling targets for quality improvement in cancer care delivery; however, little is known about how financial burden affects patient satisfaction. METHODS: This was an observational, cross-sectional, survey-based study assessing patient-reported financial burden (FB). Eligible patients were ≥ 21 years with solid tumor malignancy and were receiving chemotherapy or hormonal therapy for ≥ 1 month. The Patient Satisfaction Questionnaire Short-Form assessed patient satisfaction with health care. Subjective FB related to cancer treatment was measured on a 5-point Likert scale. RESULTS: Of 174 participants (32% response rate), 47% reported significant/catastrophic FB. Participants reported highest satisfaction with interpersonal manner and lowest satisfaction with financial aspects of care. In adjusted analysis, high FB was negatively associated with general satisfaction (coefficient: -.29), satisfaction with technical quality (coefficient: -.26), and satisfaction with financial aspects of care (coefficient: -.62). Older age was associated with higher scores in all satisfaction subscales except patient-physician communication and financial aspects. Annual household income of <$20,000 was associated with lower satisfaction scores in all subscales except time spent with doctor. High FB was not associated with patient satisfaction scores for accessibility and convenience, communication, interpersonal manner, or time spent with doctor. CONCLUSION: FB is a potentially modifiable correlate of poor satisfaction with cancer care including general satisfaction and satisfaction with the technical quality of care. Addressing cancer-associated FB may lead to improved satisfaction, which in turn can influence adherence, outcomes, and quality of life.

RESUMEN

BACKGROUND: Concerns about unsustainable costs in the US Medicare program loom as the number of retirees increase and experiences serious and costly illnesses like cancer. Engagement of stakeholders, particularly cancer patients and their families, in prioritizing insured services offers a valuable strategy for informing Medicare coverage policy. We designed and evaluated a decision exercise that allowed cancer patients and family members to choose Medicare benefits for advanced cancer patients. METHODS: The decision tool, Choosing Health plans All Together (CHAT) was modified to select services for advanced cancer patients. Patients with a cancer history (N = 246) and their family members (N = 194) from North Carolina participated in 70 CHAT sessions. Variables including participants' socio-demographic characteristics, health status, assessments of the exercise and results of group benefit selections were collected. Routine descriptive statistics summarized participant characteristics and Fisher's exact test compared group differences. Qualitative analysis of group discussions were used to ascertain reasons for or against selecting benefits. RESULTS: Patients and family members (N = 440) participated in 70 CHAT exercises. Many groups opted for such services as palliative care, nursing facilities, and services not currently covered by the Medicare program. In choosing among four levels of cancer treatment coverage, no groups chose basic coverage, 27 groups (39%) selected intermediate coverage, 39 groups (56%) selected high coverage, and 4 groups (6%) chose the most comprehensive cancer coverage. Reasons for or against benefit selection included fairness, necessity, need for prioritizing, personal experience, attention to family needs, holistic health outlook, preference for comfort, freedom of choice, and beliefs about the proper role of government. Participants found the exercise very easy (59%) or fairly easy (39%) to understand and very informative (66%) or fairly informative (31%). The majority agreed that the CHAT exercise led to fair decisions about priorities for coverage by which they could abide. CONCLUSIONS: It is possible to involve cancer patients and families in explicit discussions of their priorities for affordable advanced cancer care through the use of decision tools designed for this purpose. A key question is whether such a conversation is possible on a broader, national level.

RESUMEN

BACKGROUND: Despite increasing emphasis on the role of clinical decision-support systems (CDSSs) for improving care and reducing costs, evidence to support widespread use is lacking. PURPOSE: To evaluate the effect of CDSSs on clinical outcomes, health care processes, workload and efficiency, patient satisfaction, cost, and provider use and implementation. DATA SOURCES: MEDLINE, CINAHL, PsycINFO, and Web of Science through January 2011. STUDY SELECTION: Investigators independently screened reports to identify randomized trials published in English of electronic CDSSs that were implemented in clinical settings; used by providers to aid decision making at the point of care; and reported clinical, health care process, workload, relationship-centered, economic, or provider use outcomes. DATA EXTRACTION: Investigators extracted data about study design, participant characteristics, interventions, outcomes, and quality. DATA SYNTHESIS: 148 randomized, controlled trials were included. A total of 128 (86%) assessed health care process measures, 29 (20%) assessed clinical outcomes, and 22 (15%) measured costs. Both commercially and locally developed CDSSs improved health care process measures related to performing preventive services (n= 25; odds ratio [OR], 1.42 [95% CI, 1.27 to 1.58]), ordering clinical studies (n= 20; OR, 1.72 [CI, 1.47 to 2.00]), and prescribing therapies (n= 46; OR, 1.57 [CI, 1.35 to 1.82]). Few studies measured potential unintended consequences or adverse effects. LIMITATIONS: Studies were heterogeneous in interventions, populations, settings, and outcomes. Publication bias and selective reporting cannot be excluded. CONCLUSION: Both commercially and locally developed CDSSs are effective at improving health care process measures across diverse settings, but evidence for clinical, economic, workload, and efficiency outcomes remains sparse. This review expands knowledge in the field by demonstrating the benefits of CDSSs outside of experienced academic centers. PRIMARY FUNDING SOURCE: Agency for Healthcare Research and Quality.
