Home care program for patients at high risk of hospitalization

Objective: To assess the efficacy of a home care program designed to improve access to medical care for older adults with multiple chronic conditions who are at risk for hospitalization. Study Design: Randomized controlled trial in which participants were assigned to the home care intervention (Choices for Healthy Aging [CHA]) program or usual care. Methods: The intervention group consisted of 298 older adults at risk of hospitalization as determined by a risk stratification tool. Measures included satisfaction with medical care, medical service use, and costs of medical care. Results: The intervention group reported significantly greater satisfaction with care than usual care recipients (t test = 2.476; P = .014). CHA patients were less likely than usual care patients to be admitted to the hospital (25.6% and 37.1%, respectively; P = .02). There were no differences in terms of costs of care between the home care and usual care groups. Conclusions: Provision of home care to older adults at high risk of hospitalization may improve satisfaction with care while reducing hospitalizations. Lack of difference in medical costs suggests that managed care organizations need to consider targeting rather than using risk stratification measures when designing programs for high-risk groups.     

Satisfaction with services in innovative managed care programs for groups of traditionally underserved individuals with HIV/AIDS: empirical models

As the number of people with HIV/AIDS receiving services in managed care models increases, concerns over quality of care and satisfaction with services have grown. This article examined data from three national demonstration projects that were funded to enroll traditionally underserved individuals and provide innovative medical services in programs developing models appropriate for managed care funding. Assessments of patient satisfaction were related to indicators of traditionally underserved status including demographic characteristics, behaviors, and other risk factors using the data modeling method of Exhaustive CHAID (Chi-squared Automatic Interaction Detector). Overall patient satisfaction levels with these programs were very high. Through the modeling methods, the groups most likely to experience the greatest program satisfaction are identified. In general, all groups were highly satisfied with the programs.     

Case management of the elderly in a health maintenance organization: the implications for program administration under managed care

Kaiser Permanente initiated a two-year demonstration ambulatory case management program in its Ohio region to evaluate five outcomes: perceived health status, functional status, and satisfaction with care, service use, and service costs. Expected results were not consistently obtained for the five outcome measures. Treatment group members did not, however, experience the functional status impairments or decline in health status perceptions reported by the control group during the study period. The unexpected finding that costs were not affected may be attributed to the type of case management intervention used in the demonstration program. This study is broadly applicable to managed care settings facing the challenge of developing programs to minimize the risk for bearing the costs of the Medicare beneficiaries' overall health when all services are not covered. Managed care administrators should be favorably disposed to implementing a case management model with the potential for affecting functional status, the most significant predictor of expensive continuing care for this cohort of Medicare beneficiaries, while working to develop more effective protocols and resource control strategies.     

Satisfaction with Services in Innovative Managed Care Programs for Groups of Traditionally Underserved Individuals with HIV/AIDS: Empirical Models

SUMMARY

As the number of people with HIV/AIDS receiving services in managed care models increases, concerns over quality of care and satisfaction with services have grown.

The doctor on the patient's turf: assessing patient satisfaction with physician home visit programs.

We evaluated a physician home visit program (n = 23 patients) focusing on program implementation and quality. Quality was measured by evaluating patient satisfaction with services using a patient satisfaction scale and interviews with patients, caregivers, and providers. Scale results showed patients expressed the highest satisfaction with access to routine care and physician consideration. Patients expressed less satisfaction with access to emergency care and continuity of care. Physician communication and integration with home- and community-based service providers were other areas of concern. Recommendations include enhancing physician communication skills in the home, providing care for urgent medical conditions, improving chart documentation, and incorporating community-based chronic care experts into the program.     

Economic analysis of home vs hospital-based parenteral nutrition in Ontario, Canada

BACKGROUND: Advances in technology and infrastructure have facilitated transfer of complex services from acute care hospitals to the home. This increases the burden on community resources but may provide net savings to the health care system. We undertook a retrospective cohort study of patients transferred from hospital to home while receiving home parenteral nutrition (PN) to assess their costs of care. METHODS: A detailed review of medical records was undertaken for all patients managed by the Hamilton Health Sciences Home PN Program between 1996 and 2001 whose PN was initiated in hospital. Mean per diem direct medical costs were estimated from the perspective of the provincial Ministry of Health for 3 periods: the last 2 weeks before discharge and the first month after discharge. Costs were compared among time intervals and among patients subgroups defined by age and underlying disease. RESULTS: Twenty-nine eligible subjects were identified. Common indications for PN included malignancy (n = 12), inflammatory bowel disease (n = 6), and intestinal ischemia (n = 4). Mean per diem costs in the last week of hospitalization were higher than those in the first month after discharge (dollars 567 vs dollars 405, p < .0001). Acute care resources accounted for <10% of the overall costs on home PN. The estimated monthly savings per patient maintained on home PN were dollars 4860 (95% confidence interval dollars 2700-dollars 7000). Savings were even greater among patients with underlying malignancy and advanced age. CONCLUSIONS: Home PN is cost saving when compared with hospital-based PN. Neither age nor underlying malignancy should pose a barrier to receipt of home PN.     

The effects of medical group practice and physician payment methods on costs of care

OBJECTIVE: To assess the effects of payment methods on the costs of care in medical group practices. DATA SOURCES: Eighty-six clinics providing services for a Blue Cross managed care program during 1995. The clinics were analyzed to determine the relationship between payment methods and cost of care. Cost and patient data were obtained from Blue Cross records, and medical group practice clinic data were obtained by a survey of those organizations. STUDY DESIGN: The effects of clinic and physician payment methods on per member per year (PMPY) adjusted patient costs are evaluated using a two-stage regression model. Patient costs are adjusted for differences in payment schedules; patient age, gender, and ACG; clinic organizational variables are included as explanatory variables. DATA COLLECTION: Patient cost data were extracted from Blue Cross claims files, and patient and physician data from their enrollee and provider data banks. Medical group practice data were obtained by a mailed survey with telephone follow-up. PRINCIPAL FINDINGS: Capitation payment is correlated with lower patient care costs. When combined with fee-for-service with withhold provisions, this effect is smaller indicating that these two clinic payment methods are not interchangeable. Clinics with more physician compensation based on measures of resource use or based on some share of the net revenue of the clinic have lower patient care costs than those with more compensation related to productivity or based on salary. Salary compensation is strongly associated with higher costs. The use of physician profiles and clinical guidelines is associated with lower costs, but referral management systems have no such effect. The lower cost clinics are the smaller, multispecialty clinics. CONCLUSIONS: This study indicates that payment methods at both the medical group practice and physician levels influence the cost of care. However, the methods by which that influence is manifest is not clear. Although the organizational structure of clinics and their use of managed care programs appear to play a role, this influence is less than expected.     

A study to assess patient satisfaction of transitioning from Medicaid to managed care by sickle cell patients in Hampton Roads,Virginia

Transition issues faced by the sickle cell patient who has a significant chronic illness or disability are many and often life threatening. The problems that are faced in transitioning from Medicaid to managed care are many that could hinder the process and patient satisfaction. Such problems during the transition periods could stem from interrupted health care services; improperly coordinated services; inappropriate intervention; and inappropriate or unfounded psychologically diagnosed cases (Blum, 1993). It is not known which health care programs are cost-effective and which are not. Nor is it known which health care program best meets the needs of patients with chronic illnesses or varying levels of severity; and it is not known if health status actually improves as a result of transitioning from one program to another. What factors then impact the satisfaction levels in transitioning from Medicaid to managed care for sickle cell patients in Hampton Roads, Virginia? This study looked at patient satisfaction with the transition from Medicaid to managed care as related to the cost of care, quality of care, and access to care.     

Impact of point-of-care case management on readmissions and costs

Objective: To measure the impact of point-of-care case management by a team of diverse clinical specialists at a large medical group on 30-day readmissions and associated costs. Study Design: An intent-to-treat, historical, baseline cohort comparison design. Methods: A case management team employed by a managed care organization was integrated into the point of care at 4 medical offices of a medical group to provide services to health plan members who were medically hospitalized. Measures included case management process measures, 30-day readmissions and associated costs, and total savings. Results: Among eligible members, 93% were enrolled in the case management program. In the baseline cohort, 17.60% of members were readmitted within 30 days, compared with 12.08% in the intervention group. Regression models identified case management intervention, prospective risk score, and Medicaid insurance coverage as significantly associated with readmissions and associated costs. Annual savings in 30-day inpatient utilization costs were $1040.74 per member, which considerably exceeded the costs of the program. Conclusions: Point-of-care case management can be an effective strategy for reducing readmissions and associated costs. Providing services at the point of care allows for greater convenience for members and increased collaboration with physicians. This strategy of a managed care organization collaborating with medical groups and hospitals has the potential to enhance outcomes in accountable care organizations and to support patientcentered medical homes.     

The impact of including future medical care costs when estimating the costs attributable to a disease: a colorectal cancer case study

A source of controversy in the economic literature concerns whether to include or exclude future medical care costs when computing attributable costs for lifesaving interventions. Although it is hypothesized that including future medical care costs will offset the cost savings achieved through prevention, the magnitude of the effect is not known. The objectives of the present study are to develop a methodology for estimating the excess costs of care among colorectal cancer patients, including and excluding future costs of care, and comparing these results with previous studies that do not include costs in added years of life. Subjects in the study included those identified with colorectal cancer drawn from the Surveillance, Epidemiology and End Results (SEER)-Medicare database and an age- and gender-matched control group drawn from the general Medicare population. Using the Kaplan-Meier Sample Average estimator, we directly estimate expected 11-year costs, and then, with the addition of some simple extrapolating assumptions, determine expected 25-year costs. The latter time horizon captures lifetime costs for over 90% of the cohort. Males results for discounted, stage-specific 11- versus 25-year excess costs: in situ, 22411 dollars versus 23494 dollars; Stage 1, 29365 dollars versus 32510 dollars; Stage 2, 28114 dollars versus 25263 dollars; Stage 3, 27397 dollars versus 19647 dollars; Stage 4, 3006 dollars versus 7837 dollars. Trends were similar for females. It can be concluded that adding costs of care in future years for those whose colorectal cancer is prevented owing to screening greatly alters the estimate of lifetime excess costs for colorectal cancer patients, and can produce negative results for advanced stage disease. The results emphasize the need to adopt a standard approach for dealing with future costs when evaluating lifesaving interventions for cost-effectiveness analyses.     

The effectiveness, acceptability and costs of a hospital-at-home service compared with acute hospital care: a randomized controlled trial

OBJECTIVE: To compare the safety, effectiveness, acceptability and costs of a hospital-at-home programme with usual acute hospital inpatient care. METHOD: Patients aged 55 years or over being treated for an acute medical problem were randomized to receive either standard inpatient hospital care or hospital-at-home care. Follow-up was for 90 days after randomization. Health outcome measures included physical and mental function, self-rated recovery, health status as assessed by the SF-36, adverse events and readmissions to hospital. Acceptability was assessed using satisfaction surveys and the Carer Strain Index. Costs comprised hospital care, care in the home, community services, general practitioner services and personal health care expenses. RESULTS: In all, 285 people were randomized with a mean age of 80 years. There were no significant differences in health outcome measures between the two randomized groups. Significantly more patients receiving care at home reported high levels of satisfaction, as did more of their relatives. Relatives of the care-at-home group also reported significantly lower scores on the Carer Strain Index. However, the mean cost per patient was almost twice for patients treated at home (NZ 6524 dollars) as for standard hospital care (NZ 3525 dollars). A sensitivity analysis indicated that, if the service providing care in the home had been operating at full capacity, the mean cost per patient episode would have been similar for both modes of care. CONCLUSIONS: This hospital-at-home programme was found to be more acceptable and as effective and safe as inpatient care. While caring for patients at home was significantly more costly than standard inpatient care, this was largely due to the hospital-at-home programme not operating at full capacity.     

Meeting an expanding educational role for ambulatory care services

The mid-1980s have been marked by a growing shift in the locus of health care delivery: from the in-patient setting to ambulatory care programs. As a result of cost containment strategies--exemplified by the diagnosis related group method for hospital reimbursement--the ambulatory care network has assumed responsibility for many patients with advanced or complicated diseases. This increased responsibility is in addition to preventive services, health maintenance, and routine care of acute and chronic conditions. This shift not only requires expansion of the current system for delivery of primary care services, but will also increase the role that organized ambulatory care programs will have to play in the education of health professionals. On the basis of a ten-year experience in utilizing two county funded neighborhood health centers for primary care training of family practice residents and medical students, undergraduate and postgraduate medical education programs are discussed in terms of the changes they impose on ambulatory care program organization (e.g., staffing, space, patient assignment and consent), proposed financing, and agreements with educational institutions. The increased administrative burden of training programs is offset by benefits which include staff satisfaction, enhanced quality of care, and an increase in the pool of appropriately trained physicians.     

Hospital economics of the hospitalist

OBJECTIVE: To determine the economic impact on the hospital of a hospitalist program and to develop insights into the relative economic importance of variables such as reductions in mean length of stay and cost, improvements in throughput (patients discharged per unit time), payer methods of reimbursement, and the cost of the hospitalist program. DATA SOURCES: The primary data source was Tufts-New England Medical Center in Boston. Patient demographics, utilization, cost, and revenue data were obtained from the hospital's cost accounting system and medical records. STUDY DESIGN: The hospitalist admitted and managed all patients during a six-week period on the general medical unit of Tufts-New England Medical Center. Reimbursement, cost, length of stay, and throughput outcomes during this period were contrasted with patients admitted to the unit in the same period in the prior year, in the preceding period, and in the following period. PRINCIPAL FINDINGS: The hospitalist group compared with the control group demonstrated: length of stay reduced to 2.19 days from 3.45 days (p<.001); total hospital costs per admission reduced to 1,775 dollars from 2,332 dollars (p<.001); costs per day increased to 811 dollars from 679 dollars (p<.001); no differences for readmission within 30 days of discharge to extended care facilities. The hospital's expected incremental profitability with the hospitalist was -1.44 dollars per admission excluding incremental throughput effects, and it was most sensitive to changes in the ratio of per diem to case rate reimbursement. Incremental throughput with the hospitalist was estimated at 266 patients annually with an associated incremental profitability of 1.3 million dollars. CONCLUSION: Hospital interventions designed to reduce length of stay, such as the hospitalist, should be evaluated in terms of cost, throughput, and reimbursement effects. Excluding throughput effects, the hospitalist program was not economically viable due to the influence of per diem reimbursement. Throughput improvements occasioned by the hospitalist program with high baseline occupancy levels are substantial and tend to favor a hospitalist program.     

Utilization, costs, and access to primary care in fee-for-service and managed care plans

This study compares access to primary care, utilization, and costs among enrollees in four forms of managed care and an indemnity plan. We use 1996 data from a commercial insurer. Most managed care enrollees had better access to primary care services than indemnity enrollees. This access was associated with a generally lower rate of preventable hospitalization. Per capita inpatient costs were notably lower in managed care plans than in the indemnity plan. We describe how health care managers can use readily available administrative data and straightforward statistical techniques to enhance routine monitoring for quality and costs. Policy makers can use this approach to identify health services trends, and to evaluate access to health services for individuals enrolled in various benefit plan types.     

Medicaid chemical dependency patients in a commercial health plan

A cohort of 197 Medicaid-insured patients presenting for treatment in Kaiser Permanente's outpatient chemical dependency treatment program were observed the year prior to their program intake visit and followed for 3 years afterwards, to compare their medical costs and utilization to demographically matched commercially insured patients entering the same programs. The Medicaid-insured patients on average incurred medical costs 60% higher than non-Medicaid patients during the 12-month preintake period ($5402 vs $3377). [corrected] During the 3 years subsequently, however, both groups of chemical dependency patients displayed significant declines in medical costs, averaging 30% from the baseline period to the third year of follow-up. Cost trends reflected declines in use of hospital days, emergency department visits, and nonemergent outpatient visits. These results may help address concerns among Medicaid managed care providers and payers by giving a more realistic account of the long-term costs of this group of high-utilizing enrollees.     

Mental health and substance abuse parity: a case study of Ohio's state employee program

BACKGROUND: In the United States, insurance benefits for treating alcohol, drug abuse and mental health (ADM) problems have been much more limited than medical care benefits. To change that situation, more than 30 states were considering legislation that requires equal benefits for ADM and medical care ("parity") in the past year. Uncertainty about the cost consequences of such proposed legislation remains a major stumbling block. There has been no information about the actual experience of implementing parity benefits under managed care or the effects on access to care and utilization. AIMS OF THE STUDY: Document the experience of the State of Ohio with adopting full parity for ADM care for its state employee program under managed care. Ohio provides an unusually long time series with seven years of managed behavioral health benefits, which allows us to study inflationary trends in a plan with unlimited ADM benefits. METHODS: Primarily a case study, we describe the implementation of the program and track utilization, and costs of ADM care from 1989 to 1997. We use a variety of administrative and claims data and reports provided by United Behavioral Health and the state of Ohio. The analysis of the utilization and cost effect of parity and managed care is pre-post, with a multiyear follow-up period. RESULTS: The switch from unmanaged indemnity care to managed carve-out care was followed by a 75% drop in inpatient days and a 40% drop in outpatient visits per 1000 members, despite the simultaneous increase in benefits. The subsequent years saw a continuous decline in inpatient days and an increased use of intermediate services, such as residential care and intensive outpatient care. The number of outpatient visits stabilized in the range of 500-550 visits per 1000. There was no indication that costs started to increase during the study period; instead, costs continued to decline. A somewhat different picture emerges when comparing utilization under HMOs with utilization under a carve-out with expanded benefits. In that case, the expansion of benefits led to a significant jump in outpatient utilization and intermediate services, while there was a small decrease in inpatient days. Insurance payments in 1996/1997 were almost identical to the estimated costs under HMOs in 1993. CONCLUSIONS: In contrast to the emerging inflation anxiety regarding overall health care costs, managed care can provide long-run cost containment for ADM care even when patient copayments are reduced and coverage limits are lifted. This may differentiate ADM care from medical care and reasons for this difference include the state of management techniques (more advanced for ADM care), complexity of treatments (much higher technology utilization in medical care) and demographic factors (medical, but not behavioral health, costs increase as the population ages). IMPLICATIONS FOR HEALTH POLICY: The experience of the state of Ohio demonstrates that parity level benefits for ADM care are affordable under managed care. It suggests that the concerns about costs that have stymied ADM policy proposals are unfounded, as long as one is willing to accept managed care. IMPLICATIONS FOR RESEARCH: The continuing decline in costs raises concerns that levels of care may become insufficient. While concerns about costs being too high dominate the policy hurdle for parity legislation at this moment, the next step in research is to address quality of care or health outcomes, areas about which even less is known than about costs.     

Clinical and economic effects of coronary restenosis after percutaneous coronary intervention in a managed care population

PURPOSE: The epidemiology of coronary restenosis after percutaneous coronary intervention (PCI) has been documented extensively in clinical trials, but no data exist on the clinical and economic burden of restenosis in a managed care population. DESIGN: Retrospective cohort with a nationally representative managed care claims database (IHCIS, Waltham, Mass.) representing 2.8 million members. METHODOLOGY: Patients undergoing initial PCI between 1/1/00 and 12/31/00 (N=3,258) were identified and followed to 1 year. Clinical events, resource use, and costs between 1 month and 1 year after the initial PCI were identified. The clinical restenosis rate was estimated by multiplying the observed repeat revascularization rate by 0.85, based on previously published studies. All costs are reported from a managed care perspective in Year 2000 dollars. PRINCIPAL FINDINGS: Overall, 14.7 percent of patients required 1 or more repeat revascularization procedures between 1 month and 1 year after initial PCI, which implies an estimated clinical restenosis rate of 12.5 percent. Mean 1-year costs were nearly 6-fold higher among patients with and without repeat revascularization (dollars 31,954 +/- dollars 31,857 vs. dollars 5,474 +/- dollars 12,006, P<.001). After adjusting for baseline imbalances, the independent incremental cost for each patient with repeat revascularization was dollars 24,955 (95 percent confidence interval, dollars 23,401-dollars 26,510). Annual follow-up costs attributable to restenosis were dollars 3,118 per initial PCI recipient (i.e., dollars 24,955 x 12.5 percent). CONCLUSION: Clinical restenosis occurred in approximately 12.5 percent of real-world managed care PCI patients and increased health care costs by an average of dollars 3,118 per patient. These findings have important implications for the cost-effectiveness of new treatments that substantially reduce restenosis.     

Occupational Therapy and Low Vision Rehabilitation

This article addresses low vision rehabilitation programs and the certified occupational therapy assistant's role in a low vision, outpatient, ambulatory-care service. An individual who acquires low vision secondary to eye or brain pathology may have some useful vision but not enough to facilitate ease in performing activities of dail living. Visual tasks, such as reading, writing, homemaking and leisure activities become quite difficult without medical and therapeutic intervention. In these instances, the efforts of eye care professionals and occupational therapists can be coordinated to provide a holistic approach to patient treatment. The primary objective in utilizing a low vision rehabilitation program is to provide instruction to patients with low vision problems in activities of daily living through the use of optical/nonoptical aids to achieve functional independence.     

Expanding developmental and behavioral services for newborns in primary care: implications of the findings

BACKGROUND: In two other papers in this issue, the rationale, development, implementation, experimental design, approach to evaluation, and early results of a program to deliver developmental and behavioral services to all infants in primary care practice were described. Positive effects were seen for parental satisfaction, including decreased disenrollment, provider satisfaction, parenting practices, and health outcomes. METHODS: In the present article, the results are reviewed and implications of our findings for the delivery of care, families, healthcare systems, and further research are discussed. RESULTS: Findings that have broad implications are as follows: (1) developmental and behavioral services can be delivered successfully in practice using dedicated professionals to deliver and integrate services; (2) the "planned care model" was useful in program implementation for making "the right thing to do, the easy thing to do"; (3) the added focus on satisfaction and cost helps to develop the "business case" for broad scale implementation; (4) bonding of parents to organizations has marketing implications; (5) the program provides positive effects for all parents, not just high-risk parents; and (6) several research questions emerge, including persistence of effects on health outcomes, costs, and utilization. CONCLUSIONS: The authors conclude that study results have implications for preventive services, families, child healthcare in office practice, healthcare systems, and healthcare policy. In this ongoing study, examination of intervention effects at 30 months of age shoud be informative. Further research is warranted as it remains to be seen whether or not these interventions can become viable ongoing programs.
