Have Nursing Home Compare quality measure scores changed over time in response to competition

Nicholas G. Castle; John Engberg; Darren Liu

Background: Currently, the Centers for Medicare and Medicaid Services report on 15 Quality Measures (QMs) on the Nursing Home Compare (NHC) website. It is assumed that nursing homes are able to make improvements on these QMs, and in doing so they will attract more residents. In this investigation, we examine changes in QM scores, and whether competition and/or excess demand have influenced these change scores over a period of 1 year. Methods: Data come from NHC and the On-line Survey Certification And Recording (OSCAR) system. QM change scores are calculated using values from January 2003 to January 2004. A series of regression analyses are used to examine the association of competition and excess demand on QM scores. Results: Eight QMs show an average decrease in scores (ie, better quality) and six QMs show an average increase in scores (ie, worse quality). However, for 13 of the 14 QMs these average changes averaged less than 1%. The regression analyses show an association between higher competition and improving QM scores and an association between lower occupancy and improving QM scores. Conclusion: As would be predicted based on the market-driven mechanism underlying quality improvements using report cards, we show that it is in the most competitive markets and those with the lowest average occupancy rates that improvements in the QM scores are more likely.

The Association of Nursing Home Compare Quality Measures with Market Competition and Occupancy Rates

Nicholas G. Castle; Darren Liu; John Engberg

&NA; Since 2002, the Centers for Medicare and Medicaid Services have reported quality measures on the Nursing Home Compare Web site. It has been assumed that nursing homes are able to make improvements on these measures. In this study researchers examined nursing homes to see whether they have improved their quality scores, after accounting for regression to the mean. Researchers also examined whether gains varied according to market competition or market occupancy rates. They identified some regression to the mean for the quality measure scores over time; nevertheless, they also determined that some nursing homes had indeed made small improvements in their quality measure scores. As would be predicted based on the market‐driven mechanism underlying quality improvements using report cards, the greatest improvements occurred in the most competitive markets and in those with the lowest average occupancy rates. As policies to promote more competition in long‐term care proceed, further reducing occupancy rates, further, albeit small, quality gains will likely be made in the future.

An important focus for meaningful use criteria is to engage patients in their care by allowing them online access to their health information, including test results. There has been little evaluation of such initiatives. Using a mixed methods analysis of electronic health record data, surveys, and qualitative interviews, we examined the impact of allowing patients to view their test results via patient portal in one large health system. Quantitative data were collected for new users and all users of the patient portal. Qualitative interviews occurred with patients who had received an HbA1c or abnormal Pap result. Survey participants were active patient portal users. Our main measures were patient portal usage, factors associated with viewing test results and utilizing care, and patient and provider experiences with patient portal and direct release. Usage data show 80% of all patient portal users viewed test results during the year. Of survey respondents, 82.7% noted test results to be a very useful feature and 70% agreed that patient portal has made their provider more accessible to them. Interviewed patients reported feeling they should have direct access to test results and identified the ability to monitor results over time and prepare prior to communicating with a provider as benefits. In interviews, both patients and physicians reported instances of test results leading to unnecessary patient anxiety. Both groups noted the benefits of results released with provider interpretation. Quantitative data showed patient utilization to increase with viewing test results online, but this effect is mitigated when results are manually released by physicians. Our findings demonstrate that patient portal access to test results was highly valued by patients and appeared to increase patient engagement. However, it may lead to patient anxiety and increase rates of patient visits. We discuss how such unintended consequences can be addressed and larger implications for meaningful use criteria.

BACKGROUND When second-generation antipsychotics (SGAs), also called atypical antipsychotics, were introduced in the 1990s, early research suggested that these drugs offered better tolerability and adherence than first-generation antipsychotics (FGAs), or typical antipsychotics. This presumably would reduce the need for hospital services. However, health research to test this hypothesis has focused mostly on psychiatric readmissions. OBJECTIVE The objective of this study was to compare rates of all-cause hospitalization among patients receiving different classes of antipsychotics (SGAs, FGAs, both, or neither) in a large, all-ages sample of both institutionalized and noninstitutionalized Medicare beneficiaries. METHODS We examined the 2005 Medicare Current Beneficiary Survey Cost and Use file for 11,236 survey participants. Antipsychotic utilization was characterized in terms of class: FGA (ie, chlorpromazine, fluphenazine, haloperidol, loxapine, perphenazine, thiothixene, thioridazine, or trifluoperazine) or SGA (ie, aripiprazole, clozapine, olanzapine, quetiapine, risperidone, or ziprasidone). Hospitalization was defined in terms of whether a Medicare beneficiary was admitted to the hospital for any reason in 2005, and was measured in terms of the number of hospital visits. In our final model, we included the following confounding variables: disability status (> or =1 limitation in activities of daily living), Rosow-Breslau impairment score (difficulty with walking, stooping, crouching, kneeling, or doing heavy housework), cognitive impairment (diagnosis of Alzheimers disease or memory loss that interfered with daily activity), and health behavior variables (body mass index and smoking status). RESULTS A total of 3.5% of Medicare beneficiaries (1.3 million) filled > or =1 prescription for an antipsychotic medication in 2005. Controlling for demographic, socioeconomic, health, and disability variables, SGA-only users were more than twice as likely (odds ratio [OR] = 2.2 [95% CI, 1.7-2.9]) and combination users were more than 6 times as likely (OR = 6.3 [95% CI, 2.4-16.2]) as nonusers to be hospitalized. The odds of FGA users being hospitalized were not significantly different from nonusers (OR = 1.4 [95% CI, 0.7-2.8]). CONCLUSIONS This analysis yielded provocative, but by no means conclusive, evidence that SGAs as a class are not necessarily superior to FGAs in mitigating patients use of hospital services under real-world conditions. Systematic analysis of this relationship with a large, multiple-year sample of Medicare beneficiaries is warranted.

Does use of advanced information technology in commercial minimum data set systems improve quality of nursing home care

Darren Liu; Nicholas G. Castle; Jill C. Diesel

Information technology (IT) has been recommended to improve the quality of health care. Nursing homes use very little IT, but they have been required by the federal government to electronically submit resident assessments (via commercial Minimum Data Set [MDS] software). This article examines whether use of the advanced IT features commonly found in commercial MDS software is associated with better quality of care. This study employed a national survey of US nursing home administrators (N = 2397) regarding the use of 12 advanced IT features in commercial MDS software. Overall, the effects of using advanced IT features in commercial MDS software on quality were highly significant (P < .01) when controlling for the prior years quality as well as facility characteristics. Although nursing homes have been slow to adopt IT, the use of the identified IT in MDS software packages appears to offer the promise to improve quality of care.

Visibility and Findability of the Nursing Home Compare Website

Darren Liu; Chi-Jung Lu

Nursing Home Compare (NHC) is a federal government website providing information for selecting a nursing home. However, not many consumers were aware of or can locate the site. This study analyzed 50 official state and District of Columbia websites from September through December 2013. Using Google “inlink:” operator, this study evaluated the visibility and findability of NHC links in each state-level website. The results show that a link to NHC is available in all states except for Connecticut, Florida, and Michigan. Although it took only 4.7 clicks on average to the page with a NHC link, consumers may still have difficulty to find NHC from a state website. This article provides a snapshot of the visibility and findability of NHC and indicates a need for further investigation of promising website dissemination strategies not yet adequately evaluated.

The use of governance tools in promotion of health care information technology adoption by physicians.

Alice M. Noblin; Kendall Cortelyou-Ward; Darren Liu

Electronic health records are important technology for health care with promises of streamlining and improving care. However, physicians have been slow to adopt the technology usually because of financial constraints. Third-party payers, including Medicare and Medicaid, are coming forward with solutions and funding. While payers have the most to gain in terms of cost savings, they have been slow to provide a solution to the financial dilemmas posed by the new technology. This article details some governance tools that are frequently used to alleviate the financial concerns. Grants, loans, and tax expenditures are some of the options available to physicians to purchase electronic health records and other types of health care information technology.

Time Spent on Beneficial Leisure Activities Among Elder Caregivers in Their Third Age

Takashi Yamashita; Anthony R. Bardo; Darren Liu

ABSTRACT The Third Age is an emerging postretirement life stage characterized by better health and greater independence than previous cohorts have experienced, and recognized as an ideal time for personal growth and leisure. Yet the same demographic force that is partially responsible for this new life stage—population aging—is also driving an increased need for long-term services and supports, and Third Agers often find themselves fulfilling these caregiving roles. Thus, data from the 2013 American Time Use survey were analyzed to assess elder-caregiving-related barriers to leisure among Third Agers. While, caregivers were found to report more total leisure time and social activities, they reported less time on physical activities than noncaregivers. Results were found to differ by weekday or weekend status. Future research needs to consider specific types of leisure time use, as well as timing of leisure activities, to promote quality of life among caregivers in their Third Age.

Numeracy and Preventive Health Care Service Utilization among Middle-Aged and Older Adults in the U.S.

Takashi Yamashita; Anthony R. Bardo; Roberto J. Millar; Darren Liu

ABSTRACT Objectives: Determine whether a specific numeracy skill cut-point(s) reflects an empirical threshold in the context of preventive health service utilization, and identify associations between numeracy and preventive health services utilization among middle-aged and older adults in the United States. Methods: A nationally representative sample (n = 2,989) of adults 45 years and older from the International Assessment of Adult Competencies (PIAAC) was analyzed. Binary logistic regression was used to examine the utilization of dental checkup, vision screening, influenza vaccination, and osteoporosis screening, using multiple numeracy level classifications. Results: A dichotomous classification of numeracy skill levels (low vs. moderate to high proficiency) was associated with dental checkup utilization, but vision screening, influenza vaccination, and osteoporosis screening. Conclusions: Middle-aged and older adults with sufficient numeracy skills are more likely to have had a dental check up in the past 12 months. Findings suggest that numeracy may be more relevant for long-term vs. short-term risk assessment in determining preventive health care service utilization. Clinical Implications: Two-level numeracy categories are recommended in preventive health contexts. Numeracy proficiency-sensitive risk communication by health care providers and education programs may enhance awareness of preventive health care and promote the utilization of specific preventive health service utilization among older adults.

Literacy, Numeracy, and Health Information Seeking Among Middle-Aged and Older Adults in the United States

Takashi Yamashita; Anthony R. Bardo; Darren Liu; Phyllis Cummins

Objectives: Health literacy is often viewed as an essential skill set for successfully seeking health information to make health-related decisions. However, this general understanding has yet to be established with the use of nationally representative data. The objective of this study was to provide the first nationally representative empirical evidence that links health information seeking behaviors with health literacy among middle-age to older adults in the United States. Methods: Data were obtained from the 2012/2014 Program for the International Assessment of Adult Literacy (PIAAC). Our analytic sample is representative of adults age 45 to 74 years (N = 2,989). Results: Distinct components of health literacy (i.e., literacy and numeracy) were uniquely associated with the use of different health information sources (e.g., health professionals, the Internet, television). Discussion: Findings should be useful for government agencies and health care providers interested in targeting health communications, as well as researchers who focus on health disparities.
