Changes in inpatient mental health utilization and costs in a privately insured population, 1993 to 1995

Correlates of readmission risk and readmission days in a large psychiatric hospital in Guangzhou, China

INTRODUCTION

For many patients with psychiatric disorders, the course of illness is characterized by frequent relapses, resulting to re-hospitalization and high costs. While the correlates of readmission have been extensively studied in developed countries, few studies have examined readmission in low- and middle-income countries where bed supply is limited.

METHODS

Using administrative data from the Guangzhou Psychiatric Hospital (GPH), we used Cox regression models to evaluate the relationship among age, gender, index length of stay (LOS), and the number of previous admissions to post-discharge readmission risk. Linear regression is used to evaluate predictors of total hospital days during the year after the index discharge.

RESULTS

Between April 1, 2010 and March 31, 2011, 2,525 patients were discharged with International Classification of Diseases, 10th Revision psychiatric diagnoses from GPH, with an average LOS of 64.2 (SD = 69.0), and 317 (12.4%) were readmitted in the following year. Survival analysis showed older age (P < 0.05), and the number of previous hospitalizations (P < 0.01) were significant predictors of the risk of readmission but not diagnosis or LOS. The number of previous admissions was the only predictor of total bed days of psychiatric care at GPH in the year following the initial discharge.

DISCUSSION

Shortened LOS was not associated with increased readmission risk or post-discharge hospital days. Rather, the number of past hospitalizations was the major predictor of both readmission risk and post-discharge hospital days of psychiatric care, and such patients deserve special attention. Lowering LOS may be justified, allowing funds to be redeployed to outpatient or community-based care.

The impact of managed care on psychiatric hospitalizations and length of stay in Puerto Rico

The objective of this paper is to estimate the impact of managed care on psychiatric hospitalizations and length of stay of medically indigent residents in Puerto Rico. A quasi-experimental design and three waves of data from a random community sample were used. Results indicate that, after 2 years, managed care had minimal impact on the number of psychiatric hospitalizations; while the mean length of hospitalization decreased after implementation of managed care, this change was not significant. Based on the data in this study, the managed care initiative developed as part of health reform in Puerto Rico did not appear to affect rates of psychiatric hospitalization and produced only a nonsignificant reduction in the average length of psychiatric hospital stays. Additional research is needed to determine trends in mental health care provision in Puerto Rico based on more recent data.

Visual disfigurement and depression

Approximately 10% of the population has a facial disfigurement, such as a scar, blemish, or deformity that severely affects the ability to lead a normal life, and 2 to 3% have a clearly visible blemish. They may experience depressive symptoms due to disfigurement, stressful life events, or other causes. Depression is a painful and costly disorder that is often unrecognized and untreated in specialty practices; it is linked with higher costs of care, lengths of stay, and rates of rehospitalization. Often, these individuals seek plastic surgery to repair the disfigurement, and depressive symptoms are not uncommon preoperatively, perioperatively, and postoperatively. In addition, depressive disorders exist among 20 to 32% of people with a medical disease. Major depression is a recurring and disabling illness that typically responds to treatment with psychotherapy, antidepressants, and social support. Nurses have a major role to play in screening for and detecting depression so it can be evaluated and referred for treatment. Nurses also provide education, psychosocial support, and advocacy for patients with depression. Identifying those with depressed symptoms allows the nurse to recommend treatment, offer referrals, and provide supportive interventions.

Decision making in bipolar disorder: a cognitive modeling approach

A formal modeling approach was used to characterize decision-making processes in bipolar disorder. Decision making was examined in 28 bipolar patients (14 acute and 14 remitted) and 25 controls using the Iowa Gambling Task (Bechara et al., 1994), a decision-making task used for assessing cognitive impulsivity. To disentangle motivational and cognitive aspects of decision-making processes, we applied a formal cognitive model to the performance on the Iowa Gambling Task. The model has three parameters: The relative impact of rewards and punishments on evaluations, the impact of recent and past payoffs, and the degree of choice consistency. The results indicated that acute bipolar patients were characterized by low choice consistency, or a tendency to make erratic choices. Low choice consistency improved the prediction of acute bipolar disorder beyond that provided by cognitive functioning and self-report measures of personality and temperament.

Crisis discharges and readmission risk in acute psychiatric male inpatients

BACKGROUND

Severe pressures on beds in psychiatric services have led to the implementation of an early ("crisis") discharge policy in the Western Cape, South Africa. The study examined the effect of this policy and length of hospital stay (LOS) on readmission rates in one psychiatric hospital in South Africa.

METHODS

Discharge summaries of adult male patients (n = 438) admitted to Stikland Psychiatric Hospital during 2004 were retrospectively examined. Each patient's clinical course was then analysed for the period between January 1st, 2004, and August 31st, 2006.

RESULTS

Although shorter LOS was associated with decreased readmission rates, the effect of crisis discharges was far more powerful. Patients discharged as usual had a far lower risk of readmission than those discharged due to bed pressures (i.e. crisis discharge).

CONCLUSION

Increased risks associated with the early discharge policy necessitate the urgent review of the current management of bed shortages in this inpatient facility. The strengthening of community initiatives, particularly assertive outreach could be a way forward.

One-year health care costs associated with delirium in the elderly population

BACKGROUND

While delirium has been increasingly recognized as a serious and potentially preventable condition, its long-term implications are not well understood. This study determined the total 1-year health care costs associated with delirium.

METHODS

Hospitalized patients aged 70 years and older who participated in a previous controlled clinical trial of a delirium prevention intervention at an academic medical center between 1995 and 1998 were followed up for 1 year after discharge. Total inflation-adjusted health care costs, calculated as either reimbursed amounts or hospital charges converted to costs, were computed by means of data from Medicare administrative files, hospital billing records, and the Connecticut Long-term Care Registry. Regression models were used to determine costs associated with delirium after adjusting for patient sociodemographic and clinical characteristics.

RESULTS

During the index hospitalization, 109 patients (13.0%) developed delirium while 732 did not. Patients with delirium had significantly higher unadjusted health care costs and survived fewer days. After adjusting for pertinent demographic and clinical characteristics, average costs per day survived among patients with delirium were more than 2(1/2) times the costs among patients without delirium. Total cost estimates attributable to delirium ranged from $16 303 to $64 421 per patient, implying that the national burden of delirium on the health care system ranges from $38 billion to $152 billion each year.

CONCLUSIONS

The economic impact of delirium is substantial, rivaling the health care costs of falls and diabetes mellitus. These results highlight the need for increased efforts to mitigate this clinically significant and costly disorder.

Hospital length of stay for children and adolescents diagnosed with depression: is primary payer an influencing factor?

OBJECTIVE

This study aimed (a) to discern the distribution by primary payer (public vs. private) of U.S. patients aged 5-18 years who were hospitalized with a primary diagnosis of depression and (b) to discern the mean hospital length of stay and mean charge per day by payer type.

METHODS

The 2003 Healthcare Cost and Utilization Project Kids' Inpatient Database was used for this analysis. Depression was defined as International Classification of Diseases, 9th Revision, Clinical Modification codes 296.2-296.36, 300.4 or 311. Differences in hospital length of stay and mean cost per day by payer type were discerned via adjusted least square mean analysis (+/-S.E.).

RESULTS

The adjusted mean hospital length of stay was significantly higher (P<.0001) for patients with a public payer (6.6+/-0.05 days) versus a private payer (5.3+/-0.05 days). Although statistically significant (P<.0001), the adjusted mean charge per day differed little by payer type (public, US$1316.39+/-9.82; private, US$1357.51+/-9.07).

CONCLUSIONS

Further research is required to discern whether observed differences in hospital length of stay are the result of private payers enhancing patient care, thereby discharging patients in a more efficient manner, or the patients being discharged prematurely from the hospital due to constraints in reimbursement by private payers.

An evidence-based project to improve depression and alcohol use screening

Using research to improve practice is a high priority. Research shows that routine screening helps identify adults who are at risk for various disorders. Depression and alcohol use screening tools can improve evaluation and treatment. Nurses aimed to improve the screening rates for depression and alcohol use from the existing 50%-80% to 100% with a 1-hour educational program on depression screening and alcohol use disorders screening for 2 clinic areas: primary care and home-based care. Post program evaluation revealed that depression screening and alcohol use disorders screening rates increased to 100%.

Systematic review of the role of gender as a health determinant of hospitalization for depression

Objectives:To conduct a systematic review of selected health determinants, including gender, and their impact on hospitalization rates for depression. Depression includes both depressive and bipolar disorders. Selected health determinants were gender, age, sex, family structure, education, and socioeconomic status.

Methods:Systematic search of conventional and fugitive literature sources. All reports of primary data, systematic reviews, and meta-analysis of primary data were included if they focused on hospitalization for depression and reported data by one or more of the selected health determinants. Two researchers independently evaluated each citation for inclusion and extracted data from the included studies.

Results:There is an important underreporting of health determinants data in studies of hospitalization for depression. No studies examined the role of gender. Age and sex were reported in 83 percent and 80 percent of the 110 included studies. Women showed a higher rate of hospitalization for depression than men (p<.05). Age and diagnosis had different effects in men and women. Adult women were significantly more likely than men to report a depressive disorder, whereas men were more likely to report a bipolar disorder (p<.05). Little can be concluded on the other health determinants.

Conclusions:The importance of reporting hospitalization data and conducting hospital utilization analysis by sex and health determinants, including gender, must be emphasized.

Depression and HIV disease

Depressive disorders are common among 20% to 32% of people with HIV disease but are frequently unrecognized. Major depression is a recurring and disabling illness that typically responds to medications, cognitive psychotherapy, education, and social support. A large percentage of the emotional distress and major depression associated with HIV disease results from immunosuppression, treatment, and neuropsychiatric aspects of the disease. People with a history of intravenous drug use also have increased rates of depressive disorders. Untreated depression along with other comorbid conditions may increase costly clinic visits, hospitalizations, substance abuse, and risky behaviors and may reduce adherence to treatment and quality of life. HIV clinicians need not have psychiatric expertise to play a major role in depression. Screening tools improve case finding and encourage early treatment. Effective treatments can reduce major depression in 80% to 90% of patients. Clinicians who mistake depressive signs and symptoms for those of HIV disease make a common error that increases morbidity and mortality.

What drove private health insurance spending on mental health and substance abuse care, 1992-1999?

Trends in MH/SA treatment spending from 1992 to 1999 were examined using employer claims data from approximately 1.7 million covered lives in each year. The analysis finds that employer-based private insurance spending on MH/SA treatment did not keep pace with total employer-based private insurance spending or general price inflation. MH/SA spending dropped from 7.2 percent of total private insurance spending in 1992 to 5.1 percent in 1999. The decline was attributable to a dramatic decrease in inpatient MH/SA treatment--specifically, the probability of admissions and average length-of-stay.

Variables related to outcome following child psychiatric hospitalization

Children (N = 110) hospitalized on a child psychiatric unit improved significantly in psychological functioning at discharge and 1- and 6-months follow-up relative to their functioning at admission. Children who were more impaired at admission made more progress during admission but were more impaired at follow-up than children who had milder symptoms at admission. Children without a behavior disorder had a better outcome than children with a behavior disorder. None of the other variables, alone or in combination, was significantly related to admission progress or follow-up outcome, including specific diagnoses, gender, race, age, IQ, family functioning, negative life events, parent education and employment, biological family history, length of hospitalization, parent involvement during admission and follow-up services.

Outcome following child psychiatric hospitalization

Admission, discharge, and follow-up evaluations of 110 children admitted to a child psychiatric unit (mean 14 days) showed that the children's psychological functioning improved significantly during hospitalization. Gains were not fully maintained at follow-up (1 and 6 months), but the children were still significantly less impaired after discharge than at admission. A nonsignificant difference existed between follow-up scores, indicating no loss of progress or decline in functioning from 1- to 6-month follow-up. The results are consistent with an ABA (A = no inpatient intervention, B = inpatient intervention, A = no inpatient intervention) treatment effect. They are not explained by removal from and return to an unsatisfactory home environment. Psychological functioning after admission was significantly better than after 1 to 6 months of post-discharge psychiatric services. This study offers a clinically feasible approach to evidence-based practice by documenting patient improvement during and after inpatient treatment using a simple, empirically supported assessment instrument.

Changes in inpatient psychiatric utilization and quality of care performance measures in a capitated HMO population, 1989-1999

Managed behavioral health care approaches have significantly reduced inpatient utilization and related cost of care, but the relationship between decreased utilization and cost of care to changes in quality of care performance over time remains in question. The trends in utilization and quality of care performance measures over the course of 10 years of the Tufts Health Plan Designated Facility Program, a model health maintenance organization capitated program for inpatient behavioral health care, are presented. The results indicate that substantial decreases in inpatient utilization were sustained while quality of care measures improved over time. The data support the Tufts Health Plan Designated Facility Program as a successful means of balancing cost containment with quality of care.

Effect of declining mental health service use on employees of a large corporation

This study examines concurrent changes in use of mental and general health services and in annual sick days among 20,814 employees of a large corporation. From 1993 to 1995 mental health service use and costs declined by more than one-third, more than three times as much as the decline in non-mental health service use. However, employees who used mental health services showed a 37 percent increase in use of non-mental health services and significantly increased sick days, whereas other employees showed no such increases. Savings in mental health services were fully offset by increased use of other services and lost workdays.

Shifting to outpatient care? Mental health care use and cost under private insurance

OBJECTIVE

Concern over rising health care costs has put pressure on providers to reduce costs, purportedly by reducing inpatient care and increasing outpatient care.

METHOD

Inpatient and outpatient claims were analyzed for adult users of mental health services (180,000/year on average) from a national study group of 3.9 million privately insured individuals per year from 1993 to 1995. Costs and treatment days per patient were compared across diagnostic groups and stratified by whether patients were hospitalized.

RESULTS

Inpatient mental health costs fell $2,507 (30.4%) over the period, driven primarily by decreases in hospital days per patient per year (19.9%), with smaller changes in the proportion of enrollees who received inpatient care (increase of 0.8%) and a decrease in per diem costs (9.1%). Outpatient mental health costs also declined over the period, falling 13.6% for patients also using inpatient services and 14.6% for patients receiving only outpatient care. Patients whose primary diagnosis was mild to moderate depression saw the largest decreases in inpatient cost per patient (42.8%); those diagnosed with schizophrenia experienced the smallest decrease (23.5%). For patients using outpatient services only, those diagnosed with substance abuse experienced the largest decrease in costs (23.5%); those diagnosed with schizophrenia experienced the smallest decrease (8.6%).

CONCLUSIONS

Substantial cost reductions for mental health services are primarily a result of reductions in inpatient and outpatient treatment days. Declines in inpatient service use were not accompanied by increases in outpatient service use, even for severely ill patients requiring hospitalization. Managed care has not caused a shift in the pattern of care but an overall reduction of care.
