Improving the home health acute-care hospitalization quality measure

Causal analysis of the impact of homecare services on patient discharge disposition

This study uses observational causal inference to evaluate the impact of different combinations of home care services (nursing, therapies, social work, home aides) on end-of-episode disposition for individuals with chronic diseases associated with the circulatory, endocrine, and musculoskeletal systems. The potential to generate actionable recommendations for personalizing home care services, or treatment plans, from limited clinical and care needs data is demonstrated. For patients with chronic disease in the circulatory or musculoskeletal systems, a 2.91% and 3.38% decrease, respectively, in acute care hospitalization rates could be obtained by providing patients with therapy and nursing services, rather than therapy services alone.

Home Health Agency Characteristics and Quality Outcomes for Medicare Beneficiaries With Rehabilitation-Sensitive Conditions

OBJECTIVE

To examine associations between organizational characteristics of home health agencies (eg, profit status, rehabilitation therapy staffing model, size, and rurality) and quality outcomes in Medicare beneficiaries with rehabilitation-sensitive conditions, conditions for which occupational, physical, and/or speech therapy have the potential to improve functioning, prevent or slow substantial decline in functioning, or increase ability to remain at home safely.

DESIGN

Retrospective analysis.

SETTING

Home health agencies.

PARTICIPANTS

Fee-for-service beneficiaries (N=1,006,562) admitted to 9250 Medicare-certified home health agencies in 2009.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Institutional admission during home health care, community discharge, and institutional admission within 30 days of discharge.

RESULTS

Nonprofit (vs for-profit) home health agencies were more likely to discharge beneficiaries to the community (odds ratio [OR], 1.23; 95% confidence interval [CI], 1.13-1.33) and less likely to have beneficiaries incur institutional admissions within 30 days of discharge (OR, .93; 95% CI, .88-.97). Agencies in rural (vs urban) counties were less likely to discharge patients to the community (OR, .83; 95% CI, .77-.90) and more likely to have beneficiaries incur institutional admissions during home health (OR, 1.24; 95% CI, 1.18-1.30) and within 30 days of discharge (OR, 1.15; 95% CI, 1.10-1.22). Agencies with contract (vs in-house) therapy staff were less likely to discharge beneficiaries to the community (OR, .79, 95% CI, .70-.91) and more likely to have beneficiaries incur institutional admissions during home health (OR, 1.09; 95% CI, 1.03-1.15) and within 30 days of discharge (OR, 1.17; 95% CI, 1.07-1.28).

CONCLUSIONS

As payers continue to test and implement reimbursement mechanisms that seek to reward value over volume of services, greater attention should be paid to organizational factors that facilitate better coordinated, higher quality home health care for beneficiaries who may benefit from rehabilitation.

The impact of home health length of stay and number of skilled nursing visits on hospitalization among Medicare-reimbursed skilled home health beneficiaries

The implementation of the Home Health Prospective Payment System in 2000 led to a dramatic reduction in home health length of stay and number of skilled nursing visits among Medicare beneficiaries. While policy leaders have focused on the rising costs of home health care, its potential underutilization, and the relationship between service use and patient outcomes including hospitalization rates have not been rigorously examined. A secondary analysis of five Medicare-owned assessment and claims data sets for the year 2009 was conducted among two independently randomly selected samples of Medicare-reimbursed home health recipients (each n = 31,485) to examine the relationship between home health length of stay or number of skilled nursing visits and hospitalization rates within 90 days of discharge from home health. Patients who had a home health length of stay of at least 22 days or received at least four skilled nursing visits had significantly lower odds of hospitalization than patients with shorter home health stays and fewer skilled nursing visits. Additional study is needed to clarify the best way to structure home health services and determine readiness for discharge to reduce hospitalization among this chronically ill population. In the mean time, the findings of this study suggest that home health providers should consider the benefits of at least four SNV and/or a home health LOS of 22 days or longer.

Exploratory analysis of the relationship between home health agency engagement in a national campaign and reduction in acute care hospitalization in US home care patients

RATIONALE, AIMS AND OBJECTIVES

To determine whether US home health agencies that intensively engaged with the 2010 Home Health Quality Improvement National Campaign were more likely to reduce acute care hospitalization (ACH) rates than less engaged agencies.

METHOD

We included all Medicare-certified agencies that accessed Campaign resources in the first month of the Campaign and also responded to an online survey of resource utilization at month two. We used the survey data and item response theory to estimate a latent construct we called engagement with the campaign. ACH rates were calculated from the Centers for Medicare & Medicaid Services Outcome and Assessment Information Set for pre- and post-intervention periods (March-November 2009 and 2010, respectively).

RESULTS

Staff from 1077 agencies accessed resources in the first month of the Campaign. Of these, 382 provided information about resource use and had 10 or more monthly discharges throughout the measurement periods. Dividing these agencies into quartiles based on engagement score, we found an association between engagement and reduction in ACH rates, P=0.049 (χ(2) for trend). Exploratory path analysis revealed the effect of engagement score on reduction in ACH rate to be partially mediated through reduction in average length of service rates.

CONCLUSION

We found evidence that early intensity of engagement with the Campaign, as measured through use of activities and resources, was positively associated with improvement. To continue the investigation of this relationship, future work in this and other campaigns should focus on further development of engagement measures.

Hospitalization Among Medicare-Reimbursed Skilled Home Health Recipients

This article presents a summary and critique of the published empirical evidence between the years 2002 and 2011 regarding rehospitalization among Medicare-reimbursed, skilled home health recipients. The knowledge gained will be applied to a discussion regarding ACH among geriatric home health recipients and areas for future research. The referenced literature in MEDLINE, PubMed and Cochrane databases was searched using combinations of the following search terms: home care and home health and Medicare combined with acute care hospitalization, rehospitalization, hospitalization, and adverse events and limited to studies conducted in the United States. Twenty-five research studies published in the last eight years investigated hospitalization among patients receiving Medicare-reimbursed, skilled home health. Empirical findings indicate telehomecare can reduce hospitalizations and emergency room use. The identification of risk factors for hospitalization relate to an elder's sociodemographic, clinical and functional status that can be identified upon admission and interventions taken in order to reduce hospitalizations. Disease management, frontloading nurse visits, the structure of home health services and OBQI are also among the interventions identified to reduce hospitalizations. However, the body of evidence is limited by a paucity of research and the over reliance on small sample sizes. Few published studies have explored methods that effectively reduce hospitalization among Medicare-reimbursed skilled home health recipients. Further research is needed to clarify the most effective ways to structure home health services to maximize benefits and reduce hospitalization among this chronically ill geriatric population.

Profit status of home health care agencies and the risk of hospitalization

We examined the association of profit status and patient hospitalizations in the present-day home health care market, a market that grew substantially in the past decade, with much of that growth attributed to the entry of for-profit agencies. Data from the 2007 National Home and Hospice Care Survey were linked to the risk-adjusted agency-level measure of the percent of home health episodes of care ending in hospitalizations available from the Centers for Medicare and Medicaid Services' (CMS) Home Health Compare Web site. A linear regression model was estimated (n = 510). Control variables included other agency characteristics besides profit status, area hospital bed supply, and state dummy variables to control for state fixed effects. For-profit agencies were more likely than not-for-profit agencies to have a risk of hospitalizations greater than expected after accounting for patient characteristics and model control variables. Attributes of the CMS hospitalization measure are discussed and implications for future research described.
