Quality of care for depressed elderly pre-post prospective payment system: differences in response across treatment settings

Does prospective payment influence quality of care? A systematic review of the literature

In the light of rising health expenditures, the cost-efficient provision of high-quality inpatient care is on the agenda of policy-makers worldwide. In the last decades, prospective payment systems (PPS) for inpatient care were used as an instrument to contain costs and increase transparency of provided services. It is well documented in the literature that prospective payment has an impact on structure and processes of inpatient care. However, less is known about its effect on key outcome indicators of quality of care. In this systematic review, we synthesize evidence from studies investigating how financial incentives induced by PPS affect indicators of outcome quality domains of care, i.e. health status and user evaluation outcomes. We conduct a review of evidence published in English, German, French, Portuguese and Spanish language produced since 1983 and synthesize results of the studies narratively by comparing direction of effects and statistical significance of different PPS interventions. We included 64 studies, where 10 are of high, 18 of moderate and 36 of low quality. The most commonly observed PPS intervention is the introduction of per-case payment with prospectively set reimbursement rates. Abstracting evidence on mortality, readmission, complications, discharge disposition and discharge destination, we find the evidence to be inconclusive. Thus, claims that PPS either cause great harm or significantly improve the quality of care are not supported by our findings. Further, the results suggest that reductions of length of stay and shifting treatment to post-acute care facilities may occur in the course of PPS implementations. Accordingly, decision-makers should avoid low capacity in this area.

Surviving Depression: Clinical Qualitative Analysis of Long-Term Survival for Ethnically Diverse, Depressed Patients

Depression is persistent and recurrent across ethnic groups. Few narrative analyses of long-term outcomes for ethnically diverse adults with depression exist. We combined 9 years of quantitative data, qualitative interviews at 10 years, clinician ratings of outcomes, and a community discussion group with the objective of describing long-term recovery and survival of diverse primary care patients after an episode of depression. Nearly half of participants were found to be depressed at some time over a 10-year period, and most cases across ethnic groups were judged to need further treatment. The ethnically diverse community members that analyzed the transcripts emphasized assets that participants showed in surviving multiple life stresses. Different sex and ethnic/racial groups had different characteristics of engaging in care, with Latino women in particular raising concerns about care engagement, coping with stress, and long-term outcomes.

The effect of prospective payment on rehabilitative care

OBJECTIVES

To estimate the difference between cost and prospective payment system (PPS) reimbursements for rehabilitation care and to simulate potential consequences of cost-reducing strategies.

DESIGN

A retrospective study to estimate costs and functional status at discharge from care.

SETTING

An academic, urban, rehabilitation hospital.

PARTICIPANTS

Stroke patients on their first admission to a rehabilitation hospital between 1994 and 1998.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Cost was estimated from billing databases. Function was measured using the motor and cognitive components of the FIM instrument.

RESULTS

PPS reimbursements were 10,825 dollars (37%) lower than costs. No matter how much therapy was reduced, the costs were still greater than the mean PPS reimbursement. A reduction in length of stay by 9.6 days was required to bring costs in line with the PPS reimbursement, reducing discharge cognitive function by 1.1 points (P <.01). Use of group therapy brought costs close to PPS reimbursement amount and improved discharge cognitive function by 0.5 points (P <.10).

CONCLUSIONS

Our study shows the large difference between costs and expected PPS reimbursements that would have been observed before the PPS. Institutions have many options that reduce costs, with little effect on function at discharge. Future studies should determine the impact of evolving reimbursement rules on facilities financial status, and on patient outcomes.

The drive for quality care in US nursing homes in the era of the prospective payment system

The quality of nursing home care has often given rise to concern from many interested stakeholders. In the US, this has led to the implementation of a major legislative framework in the form of the Nursing Home Reform Act, which sought to improve the quality of care through regulation and inspections. Research has shown that certain elements of care have improved but much remains to be done. Additional pressure is now being placed on the nursing home sector through the introduction of a prospective payment system (PPS), which sets limits on reimbursement for services for Medicare-covered stays. It has been proposed that this new system of payment may lead to difficulties in accessing nursing home care for patients who are deemed to be costly, and initial assessments suggest that patients are now carefully screened before being admitted to nursing homes. This may have major implications for patients who require multiple and expensive drug therapy and other interventions. Although the Nursing Home Reform Act seeks to drive forward the quality agenda in nursing home care, research is urgently required to evaluate the impact of the PPS which may force this healthcare sector to emphasise reducing costs at the expense of residents' needs.

A health services perspective on delivery of psychiatric services in primary care including internal medicine

Serious problems persist in the recognition and treatment of psychiatric problems in primary care despite multiple interventions directed at correcting these problems. Improved outcomes depend on improved recognition, and screening instruments need to be streamlined tremendously to be accepted by primary care providers. Publication of guidelines and physician education, although essential for improved care, are probably insufficient to implement guidelines-based care. Improvements in psychiatric outcome appear to depend on the level of intensity of the intervention employed. Continued research is needed to determine the most effective type of educational intervention and more widely applicable quality improvement processes. Broad-based changes in health service delivery focusing on the true integration of mental health services with general medical care are required to bring about meaningful, effective change. Ongoing changes in physician training programs (combined primary care/psychiatry programs) may facilitate implementation of guideline-based psychiatric care in medical settings, but the full impact of these changes is not likely to be felt for several years.

Treatment of depression in older primary care patients in health maintenance organizations

OBJECTIVE

To examine whether older HMO patients with depression are treated differently than younger patients in terms of diagnosis, treatment by specialty provider, and pharmacotherapy.

DESIGN

Chart-review, Cross sectional study.

SETTING AND PARTICIPANTS

Patients were selected from six HMOs in the United States who had one or more of five medical diagnoses: arthritis, asthma, otitis media, epigastric pain/ulcer, and hypertension, (n = 9143). From this group, chart diagnoses and pharmacy records were used to identify patients who also had a diagnosis of depression (n = 416) or who had a diagnosis of depression and/or treatment with antidepressant medication (n = 1286).

MEASUREMENT

Medical records and computerized service and pharmacy records were reviewed to obtain diagnoses, office visits by provider type, and psychiatric medication prescription counts.

RESULTS

Significant differences were found in treatment of depression for older versus younger patients. Although depression was identified at a similar rate for both groups, older patients received fewer mental health specialty visits and fewer prescriptions for SSRI antidepressants. Older patients with a diagnosis of depression were more likely to be treated with benzodiazepines (49.2% of older vs. 33.2% of younger) though they were less likely to receive long half-life benzodiazepines.

CONCLUSIONS

Psychotropic medication management is an important target for improving quality of care for older patients with depression in HMOs. Decreasing inefficient minor tranquilizer use and increasing use of newer antidepressant medications may lead to improved outcomes for older depressed adults.

A review of quality evaluation systems for mental health services

Mental health quality of care evaluation systems found in an extensive search are reviewed. The quality measures are differentiated from other seemingly similar types of scales and instruments. The quality systems are reviewed in reference to 1) reliability and validity of data, type, and source of data, allowance for patient variables, standards of quality, and other parameters and 2) range and comprehensiveness, particularly with regard to coverage of the range of disorders and conditions, of age groups, care needs, care settings, treatment modalities, and of types of provider performance. Most measures were reliable and valid. Some gave consideration to patient variables and case mix, to timing, and to treatment intensity. There were no measures of providers' interpersonal performance. With regard to range and comprehensiveness, there was a substantial imbalance toward the medical model and pharmacotherapy and away from systems orientation, from psychotherapy, and from other modalities, interventions, and types of programs.
