The proportion of persons with no readmissions were 65.0%, 65.8% and 67.3% for the three years. An official website of the United States government While a fall description of the GOM subgroup profiles are presented in Appendix C, Table 2 highlights the most significant characteristics of the four groups. Hence, a post-hospital SNF stay, if it started several days after a hospital discharge, would not be recorded as the disposition of the hospital episode. 1982: 194 days1984: 199 days* Adjusted for competing risks of death and end of study. Prospective payment systems have become an integral part of healthcare financing in the United States. The post-PPS period was the one-year window from October 1, 1984 through September 30, 1985. Service Use and Outcome Analyses. Following are summaries of Medicare Part A prospective payment systems for six provider settings. Finally, the life table contains functional relationships that provide rich descriptions of the patterns that are fundamentally important to this analysis. The statistic used to test the significance of differences is the well known X2 "goodness-of-fit" statistic which is used to determine if two or more distributions are statistically significantly different. The study team chose patients admitted for one of five conditions: These conditions were chosen because they are severe and have high mortality rates. In the following sections on Medicare service use, these GOM groups are used to adjust overall utilization differences between pre- and post-PPS periods. As with the total cases, we found a slightly different pattern of risk of readmission when we focused on time intervals shortly after admission (i.e., 30 days, 90 days). Additional payment (outlier) made only if length of stay far exceeds the norm, Patient Assessment Instrument (PAI) determines assignment of patient to one of 95 Case-Mix Groups (CMGs). The computational details of such tests are presented in Manton et al., 1987. Krakauer concluded that "overall, no adverse trends in the outcomes of the medical care provided Medicare beneficiaries are discernible as yet.". Paul Eggers, Jim Vertrees, Bob Clark and Judy Sangl read earlier drafts of this report and provided many insightful comments and suggestions. Life table methodology incorporates the use of the periods of exposure of incompleted events (e.g., a nursing home stay that ends after the study) in the calculation of risks of specific outcomes. 200 Independence Avenue, SW In 1985, the corresponding rates were 6.8 percent and 21.2 percent. Manton, K.G., E. Stallard, M.A. Before sharing sensitive information, make sure youre on a federal government site. DesHarnais, S., E. Kobrinski, J. Chesney, et al. However, more Medicare patients were discharged from hospitals in unstable condition after PPS was implemented. Not surprisingly, the expected number of days before readmission were also similar--194 days versus 199 days. The study found no significant differences before and after PPS in the location of the hip fracture, associated proportions or types of comorbid conditions. lock The life table can provide estimates of the expected amount of time before readmission in addition to the probability of readmission. Prospective payment systems are intended to motivate providers to deliver patient care effectively, efficiently and without over utilization of services. The patients studied were those aged 65 years or older with a new fracture. Hence, the readmission rates for each period are not confounded by possible differences in exposure to readmission because of differences in mortality risks between the two periods. Krakauer found that while hospital admission rates continued to decline during the study period, 1983-85, there was not a significant increase in the incidence of readmissions. In a further disaggregation of the total sample of disabled older persons, in which we examined changes of specific case-mix and post-acute care subgroups, we found statistically significant differences at the .05 level in only two cases. For the 30-44 days interval, however, there was a reduction in risk of hospital readmissions of 1.1 percent in the post-PPS period. These characteristics included medical conditions, dependencies in activities of daily living (ADL) and instrumental activities of daily living (IADL). As a consequence we observed a general pattern of mortality declines in our analyses using that set of temporal windows. Hence, while hospital LOS has been noted to decrease with PPS, questions still remained about whether the observed declines were due to hospital behavior or to case-mix changes. Hence, the availability of information on a multiplicity of patient characteristics to identify potential PPS effects on specific subgroups of the Medicare population required us to examine utilization patterns in fixed intervals before and after the implementation of PPS. or From reducing administrative tasks to prompting more accurate coding and billing practices, these systems have the potential to improve financial performance while ensuring quality of care. Analyses of the characteristics of hospital admissions suggested that approximately half of the increase in post-hospital mortality was accounted for by an increase in the proportion of admissions for conditions associated with higher mortality risks. Relative to the entire population of disabled Medicare beneficiaries, Type I individuals are young, with only 10 percent being over 85 years of age.

Prospective Payment System: A healthcare payment system used by the federal government since 1983 for reimbursing healthcare providers/agencies for medical care provided to Medicare and Medicaid participants. Reflect on how these regulations affect reimbursement in a healthcare organization. This study on the effects of hospital PPS on Medicare beneficiaries has certain limitations. U.S. Department of Health and Human Services Corresponding with the reduction in this segment of stay after PPS, the authors found a reduction in the mean number of physical therapy sessions received by the patients, which declined from 9.7 to 4.9. Fourth quart The set of these coefficients describes the substantive nature of each of the K analytically defined dimensions just as the set of factor loadings in a factor analysis describes the nature of the analytically determined factors. Houchens. Prospective payment systems are intended to motivate providers to deliver patient care effectively, efficiently and without over utilization of services.The concept has its roots in the 1960s with the birth of health maintenance organizations (HMOs). While the proportion of HHA episodes resulting in hospital admission was lower, the proportion of HHA episodes discharged to the other settings increased. The remaining four parts address different service use and outcome patterns of the subgroup of Medicare beneficiaries who have chronic disabilities. In the following sections, we first discuss the background for this study. Rheumatism and arthritis (58%)"Young-Olds" (10% over 85)50% married53% male67% good-excellent health on subjective scale3% with prior nursing home stay47% with no helper days, Problems with transfer (72%), mobility, toileting and bathingAll IADLsHip fractures (8%: RR=3:1), other breaks (14%: RR=2:1)GlaucomaCancer50% over 85 years old70% not married70% female22% prior nursing home stay (RR=2:1)Home nursing service (.25) and therapist (.06), Bathing dependent and IADLs100% arthritis, 62% permanent stiffness45% diabetes, 50% obeseHighest risks of cardiovascular and lung diseases95% female95% under 85, 60% with ADL for eating, 100% all other ADLsBedfast (11%); chairfast (32%)70% incontinent (27% with catheter or colostomy)Parkinsons, mental retardation (10%)Senile (60%)Stroke, some heart and lung48% male, 58% married, 25% over 85, 20% Black80% with poor subjective health19% with prior nursing home use. First, multivariate profiles or "pure types" are defined by the probability that a person in a given group or pure type has each of the set of characteristics or attributes. One expected result of reductions in hospital admissions, as a result of the "channeling effects" would be a more severe case-mix of hospital admissions. Unlike other studies assessing PPS effects, our study population focused on disabled, noninstitutionalized. This analysis focused on hospital admissions and outcomes of these admissions in terms of hospital readmissions. Home health episodes were significantly different with overall LOS decreasing from 108 days to 63 days. Table 12 presents the schedule of probabilities of hospital readmission for pre- and post-PPS periods, and the difference in probabilities between the two periods. Explain the classification systems used with prospective payments. For example, the proportions of hospital episodes resulting in readmission within the one-year observation periods were 39.3% pre-PPS and 38.4% post-PPS. The earliest of the ACA's provisions related to provider reimbursement have slowed growth in fee-for-service payment levels. Table 15 presents the mortality patterns of hospital episodes stratified by use of Medicare SNF, Medicare home health and no post-acute Medicare services. The purpose of this study was to provide empirical information on Medicare hospital PPS effects on an important subgroup of Medicare beneficiaries, the functionally disabled. Table 15 also presents, for persons who died, the proportion of deaths that occurred within 30 and 90 days in the given type of episode. For information on reprint and reuse permissions, please visit www.rand.org/pubs/permissions. They posited that the observed change in location of death could reflect both a less aggressive use of hospital resources by physicians caring for terminally ill patients and a transfer of seriously ill patients to nursing homes for terminal care. Because of this, GOM is distinct from the classification methodology used to identify the DRG categories or hospital reimbursement by which homogeneous discrete groups are defined in terms of the variation of a single criterion (i.e., charges or length of stay) except where clinical judgment was used to modify the statistically defined groups; and each case is assigned to exactly one group and thus does not represent individual heterogeneity in the classification. Interprofessional Education / Interprofessional Practice, Inpatient rehabilitation hospital or distinct unit, Resource Utilization Groups, Third Version (RUG-III), Each day of care is classified into one of four levels of care. We discuss the GOM methodology in greater detail in the following section on statistical methodology. Table 6 presents the patterns of discharge for HHA episodes. In our analysis of the distribution of deaths at specified intervals of time after hospital admission, we found higher proportions of death occurring in a short period of time after admission. They may also increase the risks that hospital patients are discharged inappropriately and have to be readmitted. A clear interpretation of this finding requires, however, a data set that can determine what other services and where such individuals were receiving care. HCFA Contract No. In examining the length of time and percent of cases that terminate in a particular way we see that the nondisabled community elderly and the institutionalized elderly have slight increases in hospital episodes ending in death with the community disabled experiencing virtually no change. The HMO receives a flat dollar amount (i.e., monthly premiums) and is responsible for providing whatever services are needed by the patient. An essential attribute of a prospective payment system is that it attempts to allocate risk to payers and providers based on the types of risk that each can successfully manage. The payment amount is based on a unique assessment classification of each patient. The program pays hospitals a prospectively determined amount for each Medicare patient treated depending on the patient's diagnosis. Second, since the analysis identifies "K" sets of discrete profiles, each with their own characteristic relationships to the variables of interest, subgroup variable interactions are directly represented in the analysis. PPS changed the way Medicare reimbursed hospitals from a cost or charge basis to a prospectively determined fixed-price system in which hospitals are paid according to the diagnosis-related group (DRG) into which a patient is classified. Hall, M.J. and J. Sangl. In addition, the researchers found that an observed 8.7 percent decrease in Medicare hospital admission rates between the two years was primarily caused by a decline in the hospitalization of low severity patients. The CPHA researchers concluded that, while the results of the study provided initial insights, further analysis on the effects of PPS was required because of identifiable limitations of the study (DesHarnais, et al., 1987). how do the prospective payment systems impact operations? Finally, since the analysis generates coefficients that describe how each person is related to each of the basic profiles, it offers a strategy for generating continuous measures of severity determined by a wide range of interacting medical and disability conditions. However, insurers that use cost-based . While the first three studies examined effects of PPS in multiple hospitals in multiple states, two other studies focused on more circumscribed populations. (Part B payments for evaluation and treatment visits are determined by the, Primary diagnosis determines assignment to one of 535 DRGs. Other measures included length of hospital stay, status at discharge, discharge destination (home or other care facility), prolonged nursing-home stays, and readmissions. For example, all of the hospital episodes in our sample, whether they were the first, second or third hospitalization during the observation window, were included as an individual unit of observation. To assist our community with this payment, the pensioner rebate applied against the water infrastructure charge has been doubled from $35 per annum to $70 to help pensioners with the cost of the water charges. They assembled a nationally representative data set containing cost, outcome, and process-of-care information on 16,758 Medicare patients hospitalized in one of 300 hospitals across five states (California, Florida, Indiana, Pennsylvania, and Texas). Our analysis suggested that the overall patterns of hospital readmission risks were not different between the one year pre- and post-PPS observation periods. The net increase for this interval was 0.7 percent between 1982 and 1984. STAY IN TOUCHSubscribe to our blog. We also found that, for community dwellers (both disabled and non-disabled), there were compensating decreases in mortality in Medicare SNF and HHA service episodes suggesting that more serious cases were being transferred to hospitals more efficiently. Each option comes with its own set of benefits and drawbacks. Thus, the benefits of prospective payment systems are based on shifting the risk of treating a population of patients to the provider, formulating a fair payment structure that encourages providers to deliver high-value healthcare. As noted in the figure, the number of such patients increased by 3 percentage points (a 22-percent rise). For example, while a schedule of conditional probabilities of hospital readmissions can be produced, these probabilities do not tell us how much time passed before the readmission. We did not find overall changes in mortality among hospital patients between pre- and post-PPS periods, although an increased risk of mortality was indicated for the short-term (e.g., within 30 days of the initiating admission). Statistically significant differences (p = .05) between 1982 and 1984 were detected in the hospital, length of stay for this group. The association between increases in SNF admissions and decreases in hospital LOS suggests the possibility of service substitution among the "Mildly Disabled." Because of the recent introduction of PPS, relatively few evaluation results have been available to study its effects on Medicare service use and patients. The Prospective Payment System In response to payment growth, Congress adopted a prospective payment system to curtail the amount of resources the Federal Government spent on medical care for the elderly and disabled.

In a further analysis of these measures, the hospital cases were stratified by whether they were followed by post-acute SNF or HHA use. The collective results of the study led the authors to conclude that there was no evidence to indicate that the quality of care has declined during the first two years of PPS. Although prospective payment systems offer many benefits, there are also some challenges associated with them. Bundled payment interventions may aggregate costs longitudinally (i.e., over time within a single provider), aggregate costs across providers, and/or involve warranties The authors noted that since changes in hospitalization were seen only in the institutionalized population, the possibility existed that the frail elderly may represent a unique segment of the Medicare population that is vulnerable to the changes in health care provision encouraged by PPS. Mortality rates for patients with the given conditions did not increase after PPS. , Passaic County Community College Seton Hall University. The probability of a hospital readmission between the initial admission date and the subsequent 15 days was 3.8 percent in 1982-83 and 4.1 percent in 1984-85, a likelihood of hospital readmission in the post-PPS period higher by 0.3 percent. By following these best practices, prospective payment systems can be implemented successfully and help promote efficiency, cost savings, and quality care across the healthcare system. The authors reported that during the 12 months following the implementation of PPS, Wisconsin's institutionalized elderly Medicaid population experienced a 72 percent increase in the rate of hospitalization and a 26 percent decline in hospital length of stay. Instead, the RAND team undertook a massive data-collection effort. The GOM techniques identified an optimum number of case-mix profiles based on maximum likelihood estimation of the set of health and functional status characteristics from the 1982 and 1984 NLTCS. In addition, changes in patterns of hospitalization were compared between the institutionalized and noninstitutionalized elderly patients. PPS represents a radically different approach to paying for care than the retrospective cost-based reimbursement system it replaced. Distinct from prior studies which addressed the general Medicare population, our analysis focused on PPS effects on disabled elderly Medicare beneficiaries. By focusing on each episode of service use as a unit of observation, the analysis was able to include all episodes of the samples without benchmarking for a specific event, such as the first admission during the pre and post-PPS observation windows. Events of interest to the study were analyzed in two ways. The study also found an increase in the proportion of patients discharged to skilled nursing facilities after hospitalizations, from 21 percent to 48 percent. Stern, R.S. The next four tables highlight the Medicare service use patterns of each of the four GOM subgroups. Overall, our analysis indicated no system-wide changes in hospital readmission risks between the pre- and post-PPS periods for hospital episodes. The two types of GOM coefficients can be associated with the two types of results. There were indications of service substitution between hospital care and SNF and HHA care. Improvements in hospital management. Providers must make sure that their billing practices comply with the new rates as well as all applicable regulations. The Grade of Membership analysis of the period 1982-83 and 1984-85 NLTCS data produced four relatively homogeneous subgroups. The NLTCS allowed a broad characterization of cases including multiple chronic complications or co-morbidities and physical and cognitive impairments. The Pardee RAND Graduate School (PardeeRAND.edu) is home to the only Ph.D. and M.Phil. This finding suggests that in spite of the financial incentives, hospitals were unable to reduce LOS for certain types of patients. The implementation of a prospective payment system is not without obstacles, however. Medicare's DRG system is called the Medicare severity diagnosis-related group, or MS-DRG, which is used to determine hospital payments under the inpatient prospective payment system (IPPS). Yashin. In a second study, Krakauer (HCFA, 1987) analyzed the effectiveness of care provided to Medicare beneficiaries during hospitalization and thereafter in 1983-85. Hospital Utilization. "Institutional Responses to Prospective Payment Based on Diagnosis-Related Groups," N Engl J Med, 312:621-627. Funds were also provided by the Health Care Financing Administration. Since we cannot observe a readmission after the study ends, our results could be biased and misleading if we did not account for this censoring. However, the impact on mortality of discharge in unstable condition did not outweigh other quality improvements, because overall mortality fell. The rate of reimbursement varies with the location of the hospital or clinic. There were no statistically significant differences before and after PPS in the patterns of hospital, SNF and HHA episodes. Thus, an groups experienced notable declines in hospital LOS with the institutionalized having the largest decline (i.e., 2.0 days). Prospective payment. This uncertainty has led to third-party payers moving towards prospective payment methodologies. Continuous Medicare Part A bills permitted a tracking of persons in the NLTCS samples through different parts of the health care system (i.e., Medicare hospital, SNF and HHA) so that we could examine transitions from acute care hospitals to subsequent experience in Medicare SNF or HHA services. As these studies are completed, policy makers will have a better understanding of the effects of PPS on the provision and outcomes of various t3rpes of Medicare as well as non-Medicare services. Except for acute care hospital settings, Medicare inpatient PPS systems are in their infancy and will be experiencing gradual revisions. For the total elderly population we see that the pattern is erratic with death rate "peaks" in 1983 and 1985 and with the lowest mortality rates for 1986. By "significant" we mean whether or not the life tables estimated for each case mix group differ from those for the total population by more than chance. Sager, M.A., E.A. The analysis suggested that the shorter Medicare stays are being supplemented with more use of home health agencies for post-discharge care. and S. Harrison. Table 11 presents the patterns of service use for the "Severely Disabled" group, which was characterized by heavy ADL dependency, neurological problems, stroke, and senility. A linear forecasting model to project 1984 measures of utilization and outcomes based on trends from 1980 to 1983 was developed to compare the expected 1984 measures to observed 1984 measures. Because the PPS system has been introduced only recently, evaluations of the effects of the policy on Medicare beneficiaries have been limited. The characteristics of the four subgroups suggested different needs for Medicare services and different risks of various outcomes such as hospital readmission and mortality. With Medicare Part A bills for the NLTCS samples of approximately 6,000 persons in 1982 and 1984, this study compared utilization patterns in one-year periods pre-PPS (1982-83) and post-PPS (1984-85). Neither of these changes were significant. Easterling. Abstract In a longitudinal panel study design, 80 hospitals in Virginia were selected for analysis to test the hypothesis that the introduction of the prospective payment system (PPS) in October 1983 had helped hospitals enhance their operational performance in technical efficiency. Appendix A discusses the technical details of GOM analyses. Subgroups of the Population. Lastly, by creating a predictable prospective payment plan structure with standardized criteria, PPS in healthcare helps providers manage their finances while also helping to ensure patients receive similar quality care. Several studies have examined PPS effects on the total Medicare population. We measured changes in hospital use, and use of post-acute SNF and HHA services, hospital readmissions and mortality during and after hospital stays. Neu, C.R. Jossey-Bass, pp.309-346. For example, because of the relatively small number of Medicare SNF episodes, all SNF episodes were drawn for the analysis. It doesn't matter how the property passes to the inheritor.State Supplemental Pay System Page 7 Recommendations: 1. All but three of the bundled payment interventions in the included studies included public payers only. Subscribe to the weekly Policy Currents newsletter to receive updates on the issues that matter most. In the fifth study, Fitzgerald and his colleagues studied the effects of PPS on the care received by hospitalized hip fracture patients. However, this definition was applied uniformly for both pre- and post-PPS periods, and we are not aware of any systematic differences in the onset of post-acute services between the two time periods. Comparisons were then made between the expected (severity adjusted) mortality rate and the observed 1985 mortality rates. In contrast to post-acute SNF care, there was a distinct increase in the use of home health services that followed hospital discharges as well as Medicare SNF discharges. The site is secure. By termination status of SNF episodes, there was a reduction in discharge from SNFs to hospitals from 30.6 percent in the pre-PPS period to 18.0 percent in the post-PPS period. Type IV, the severely disabled individuals with neurological conditions, would be expected to be users of post-acute care services and long-term care, and at high risk of mortality. Everything from an aspirin to an artificial hip is included in the package price to the hospital. All these measures were adjusted to take into account the severity of patient sickness at admission. An outpatient prospective payment system can make prepayment smoother and support a steady income that is less likely to be affected by times of uncertainty. Life Table Analysis. Fifty-six (56) medical conditions, ADLs and IADLs were used in this analysis. Hospital, SNF and HHA service events were analyzed as independent episodes. There was a decline in average LOS for all SNF episodes from 69.9 days to 37.7 days.
