Evaluating the utility of existing patient-reported outcome scales in novel patient populations with pancreatic cancer, lung cancer, and myeloproliferative neoplasms using medicare current beneficiary survey data

Pancreatic Cancer Surgery: What Matters to Patients?

Pancreatic cancer is a leading cause of cancer-related death, with a poor overall survival rate. Although certain risk factors have been identified, the origins of pancreatic cancer are still not fully understood. Surgical resection remains the primary curative treatment, but pancreatic surgery is still associated with high morbidity and mortality rates, and most patients will experience recurrence. The impact of pancreatic cancer on patients' quality of life is significant, with an important loss of healthy life in affected individuals. Traditional outcome parameters, such as length of hospital stay, do not fully capture what matters to patients during recovery. Patient-centered care is therefore central, and the patient's perspective should be considered in pre-operative discussions. Patient-reported outcome and experience measures (PROMs and PREMs) could play an important role in assessing patient perspectives, but standardized methodology for evaluating and reporting them is needed. This narrative review aims to provide a comprehensive overview of patient perspectives and different patient-reported measures in pancreatic cancer surgery. Understanding the patient perspective is crucial for delivering patient-centered care and improving outcomes for patients with pancreatic cancer.

The Role Of Social, Cognitive, And Functional Risk Factors In Medicare Spending For Dual And Nondual Enrollees

The Centers for Medicare and Medicaid Services is increasingly focused on value-based payment programs, which tie payment to performance on quality and cost measures. In this context, there is rising concern that such programs systematically disadvantage providers that care for vulnerable populations, such as the poor, by holding the providers accountable for factors beyond their control that influence patient outcomes and utilization. In this nationally representative study of Medicare beneficiaries, we found that dually enrolled Medicare beneficiaries (those also enrolled in Medicaid) had strikingly higher levels of medical, functional, and cognitive comorbidities, as well as social needs, compared to their non-dually enrolled counterparts. Dual enrollees also had significantly higher annual costs of care. Including functional, cognitive, and social factors in cost prediction, in addition to risk factors derived from medical claims, improved risk prediction and decreased differences between dual and nondual enrollees. Medicare could consider such adjustment to improve accuracy and fairness in value-based payment programs.

Association of Patient Social, Cognitive, and Functional Risk Factors with Preventable Hospitalizations: Implications for Physician Value-Based Payment

BACKGROUND

Ambulatory care-sensitive condition (ACSC) hospitalizations are used to evaluate physicians' performance in Medicare value-based payment programs. However, these measures may disadvantage physicians caring for vulnerable populations because they omit social, cognitive, and functional factors that may be important determinants of hospitalization.

OBJECTIVE

To determine whether social, cognitive, and functional risk factors are associated with ACSC hospitalization rates and whether adjusting for them changes outpatient safety-net providers' performance.

DESIGN

Using data from the Medicare Current Beneficiary Survey, we conducted patient-level multivariable regression to estimate the association (as incidence rate ratios (IRRs)) between patient-reported social, cognitive, and functional risk factors and ACSC hospitalizations. We compared outpatient safety-net and non-safety-net providers' performance after adjusting for clinical comorbidities alone and after additional adjustment for social, cognitive, and functional factors captured in survey data.

SETTING

Safety-net and non-safety-net clinics.

PARTICIPANTS

Community-dwelling Medicare beneficiaries contributing 38,616 person-years from 2006 to 2013.

MEASUREMENTS

Acute and chronic ACSC hospitalizations.

RESULTS

After adjusting for clinical comorbidities, Alzheimer's/dementia (IRR 1.30, 95% CI 1.02-1.65), difficulty with 3-6 activities of daily living (ADLs) (IRR 1.43, 95% CI 1.05-1.94), difficulty with 1-2 instrumental ADLs (IADLs, IRR 1.54, 95% CI 1.26-1.90), and 3-6 IADLs (IRR 1.90, 95% CI 1.49-2.43) were associated with acute ACSC hospitalization. Low income (IRR 1.28, 95% CI 1.03-1.58), lack of educational attainment (IRR 1.33, 95% CI 1.04-1.69), being unmarried (IRR 1.18, 95% CI 1.01-1.36), difficulty with 1-2 IADLs (IRR 1.30, 95% CI 1.05-1.60), and 3-6 IADLs (IRR 1.44, 95% CI 1.16-1.80) were associated with chronic ACSC hospitalization. Adding these factors to standard Medicare risk adjustment eliminated outpatient safety-net providers' performance gap (p < .05) on ACSC hospitalization rates relative to non-safety-net providers.

CONCLUSIONS

Social, cognitive, and functional risk factors are independently associated with ACSC hospitalizations. Failure to account for them may penalize outpatient safety-net providers for factors that are beyond their control.

Association Between Patient Cognitive and Functional Status and Medicare Total Annual Cost of Care: Implications for Value-Based Payment

IMPORTANCE

Medicare is moving toward value-based payment. The Merit-Based Incentive Payment System (MIPS) program judges outpatient clinicians' performance on a measure of annual Medicare spending. However, this measure may disadvantage outpatient clinicians who care for vulnerable populations because the algorithm omits meaningful determinants of cost.

OBJECTIVES

To determine whether factors not included in Medicare risk adjustment, including patient neuropsychological and functional status, as well as local area health resources and economic conditions, are associated with Medicare total annual cost of care (TACC), and evaluate whether accounting for these factors is associated with improved TACC performance by outpatient safety-net clinicians.

DESIGN, SETTING, AND PARTICIPANTS

In this retrospective observational study, we used the Medicare Current Beneficiary Survey (MCBS) to examine patient-reported neuropsychological and functional status and the Area Health Resources File to obtain information on local area characteristics. Included were Medicare beneficiaries with annual physician or clinic visits to outpatient safety-net (federally qualified health centers and rural health clinics) and non-safety-net clinics, contributing 76 927 person-years of data to the MCBS from 2006 through 2013. We used patient-level multivariable regression models to estimate the association between each factor and annual Medicare spending, and compared outpatient safety-net performance under current risk adjustment and after adding additional adjustment for these factors.

MAIN OUTCOMES AND MEASURES

Medicare TACC, measured as the total annual reimbursed amount per patient for Medicare Part A and Part B services, in all categories.

RESULTS

Our study included 111 414 unique identifiable physicians, and the final weighted sample included 213 904 324 patient-years (unweighted, 76 927 patient-years) from 30 058 unique patients, of whom 17 478 (58.1%) were women. The mean (SD) patient age was 71.84 (12.48) years. The mean TACC was $9117. Those with higher than mean TACC included beneficiaries with depression ($14 436), dementia ($18 311), and difficulty with 3 or more activities of daily living (ADLs, $19 113) or instrumental ADLs ($17 443). After adjusting for comorbidities, depression and dementia were still associated with $2740 (95% CI, $2200-$2739) and $2922 (95% CI, $2399-$3445) higher TACC, respectively. Difficulty with 3 or more ADLs ($3121 higher; 95% CI, $2633-$3609) or instrumental ADLs ($895 higher; 95% CI, $452-$1337) was also associated with higher TACC. Adding these neuropsychological and functional factors, as well as local residence area factors, to risk adjustment calculations reduced outpatient safety-net clinicians' underperformance on Medicare TACC relative to non-safety-net clinicians by 52% (from 0.098 to 0.047 difference in the observed to expected ratio).

CONCLUSIONS AND RELEVANCE

Neuropsychological and functional impairment are common in Medicare beneficiaries and are associated with increased annual Medicare spending. Failure to account for these factors may inappropriately penalize outpatient clinicians who care for these vulnerable groups, such as safety-net clinicians, for factors that are arguably beyond their control.

Real-world characteristics of elderly patients with overactive bladder in the United States

OBJECTIVES

Although much has been published about the demographic and clinical characteristics of elderly patients with overactive bladder (OAB) who were enrolled in clinical trials, very little is known about the general population of elderly Americans with OAB. We update this gap in the literature by using real-world data to describe this population.

METHODS

We used Medicare claims and the Medicare Current Beneficiary Surveys from 2006 to 2011 to identify patients with OAB. We describe the demographic characteristics, functional impairment and physical limitations, concurrent medical conditions, Charlson Comorbidity Index (CCI) scores, and concomitant medication use of patients with OAB; these characteristics are also described by sex and age group (65-74 vs. ≥75 years). We also compare the characteristics of OAB with non-OAB patients.

RESULTS

We identified 415 elderly patients with OAB (average age 79 years; 71% female) and 6868 without OAB (average age 77 years; 62% female). Patients with OAB reported high levels of functional impairment as measured by the Activities of Daily Living (44% vs. 33% for non-OAB patients), Instrumental ADL (53% vs. 40% for non-OAB patients), and physical functioning limitation (90% vs. 81% for non-OAB patients) scales. Elderly patients with OAB also experienced high levels of comorbidity burden, as measured by the number of medical conditions (18 vs. 11 for non-OAB patients), CCI (2.1 vs. 1.4 for non-OAB patients), and number of non-OAB-related concomitant medications used (11 vs. 8 for non-OAB patients).

CONCLUSIONS

Elderly patients with OAB in the general population have high levels of functional impairment and physical limitations, comorbidity, and concomitant medication use. These characteristics should be taken into consideration when managing OAB symptoms and designing future clinical studies. These results, which are representative of elderly patients with OAB in the general US population, should, however, be interpreted in light of the key limitations of the data we used: patients may have been misclassified and medical conditions overestimated due to artifacts of diagnosis coding and our results can only be generalized to patients who were enrolled in Medicare Parts A, B, and D for at least 12 continuous months.

Assessment of an Expanded Functional Disability Scale for Older Adults With Diabetes

Although prior literature has shown the plausibility of combining the Activities of Daily Living (ADL) and Instrumental Activities of Daily Living (IADL) items to form an expanded scale for measuring the degree of functional decline, this has not been shown in older adults with diabetes who are disproportionately affected by functional disability. Using the 2009 Medicare Current Beneficiary Survey data, we evaluated the factor structure of the pooled ADL and IADL items. Based on our study comprising 2,158 community-dwelling older adults (≥65 years) with diabetes, the unidimensional model exhibited good fit. Despite well-fitting indices, high correlations were observed between the latent constructs (>.70) of the multi-factor models, suggesting a lack of discriminant validity. These findings provide empirical support for a combined scale that can comprehensively and efficiently characterize the extent of functional disability in older adults with diabetes for research, risk adjustment, and evaluation in patient-centered medical homes.
