Psychiatric Care in General Hospitals With and Without Psychiatric Units: How Much and for Whom

1. Psychiatric Care in General Hospitals With and Without Psychiatric Units: How Much and for Whom?  Tami L. Mark, Thomson Reuters Elizabeth Stranges, Thomson Reuters Rita Vandivort-Warren, SAMHSA Carol Stocks, AHRQ Pam Owens, Consultant AHRQ 2009 AHRQ Annual Conference September 14, 2009

2. 2 Background Despite the shift from long term inpatient stays to community treatment, hospitalization remains a key component of mental health care today, primarily for people in crisis Most inpatient psychiatric treatment occurs in general acute care hospitals rather than specialty psychiatric hospitals General hospital psychiatric care can be provided in two distinct ways Psychiatric Units: Set up and staffed specifically for psychiatric treatment Separate, often locked, space within hospital “Scatter Beds” General medical care beds located throughout the hospital

3. 3 Public Policies Affecting Psychiatric Unit Supply and Demand Decline in beds in public psychiatric hospitals and more recently private psychiatric hospitals

4. Change in Psychiatric Beds in U.S.

5. Public Policies Affecting Psychiatric Unit Supply and Demand PPS Exemption of Psychiatric Units, October 1983 Managed Care Limits on Inpatient Care in 1990s PPS implementation, January 2005 IMD Exclusion encourages use of psych units in community hospitals Medicaid will not pay for inpatient treatment for persons age 21-64 who receive care in an “institution for mental disease”, defined as an institution of more than 16 beds that primarily treats people with mental illness

6. 6 Shortage of Psychiatric Beds? Overcrowding in emergency rooms due to psychiatric patients Many hospitals report “ED boarding” of patients with psychiatric illness Survey of state mental health authorities revealed that more than 80 percent of states reported a shortage of psychiatric beds

7. 7 Research Questions How much psychiatric care in general hospitals is occurring in psychiatric units and how much in scatter beds? What types of patients are being treated in psychiatric units and what types in scatter beds?

8. Motivation To what extent are patients treated in community hospitals receiving the specialized services that psychiatric units offer? Are scatter beds being used more in regions where there are not specialized units to supplement psychiatric beds? Are scatter beds being used primarily to treat medical comorbid conditions or do patients being treated there primarily have psychiatric conditions?

9. 9 Outline Data Sources Prior Research Part 1: Number of community hospital psychiatric patients treated in psychiatric units vs scatter beds Part 2: Characteristics of patients treated in psychiatric units and scatter beds Conclusions

10. 10 Data Sources on Care in Psychiatric Units American Hospital Association Survey of Hospitals Medicare Cost Reports SAMHSA Survey of Mental Health Specialty Facilities (IMHO, SMHO) HCUP-SID Revenue Codes

11. 11 Prior Research Kiesler & Simpkins: The Unnoticed Majority in Psychiatric Inpatient Care, 1995 Methods 1980 Hospital Discharge Survey by NCHS Identified psychiatric unit using NIMH survey of psychiatric units (now carried out by SAMHSA) and AHA Findings In 1980, 38% of psychiatric inpatient episodes in community hospitals occurred in scatter beds

12. Part I: Estimating the Percent of Psychiatric Discharges from General Hospitals in Psychiatric Units and Scatter Beds

13. 13 Methods HCUP-SID discharges (2000 – 2006) Total number of discharges from community hospitals in participating states Examined those with principal psychiatric diagnoses (excluding substance abuse) Linked to Medicare Cost Report through AHA ID Information on whether have PPS exempt psychiatric unit Checked information on psychiatric unit against volume of MH discharges With additional web searching for verification

14. 14 Study Sample (2006)

15. 15 Of Community Hospitals, 27% Have Psychiatric Units, Down from 36% in 2002

16. 16 About 20% of Discharges are from Hospitals without Psychiatric Units Based on MCR and SID

17. Psychiatric Discharges Across States

18. 18 Summary of Analysis Thus Far Summary: About 20% of discharges from hospitals without psychiatric units Maybe over-estimate scatterbeds: Assumes no under-reporting of psychiatric units by hospitals Maybe under-estimate scatterbeds: Assumes that all discharges from hospitals with psychiatric units are from psychiatric units

19. 19 Under Reporting Analysis 94% of community hospitals without an MCR psychiatric unit indicator had less than 100 MH discharges (based on HCUP-SID counts). 6% of hospitals without an MCR psychiatric unit indicator had 100 or more MH discharges 39 of the 50 hospitals (78%) with >100 MH discharges but no MCR indicator had a psychiatric unit indicated on their website Conclusion: Discharge volume can be used to impute missing MCR psychiatric unit status

20. 20 About 2% of Discharges from Hospitals without Units (If > 100 MH discharges is used as a proxy for a unit)

21. 21 Over Estimation Analysis Used revenue codes for room & board charges for 12 states to examine whether discharges had revenue codes indicating psychiatric unit room and board charge Found 3.6% of discharges from hospitals with psychiatric units were from scatter beds

22. 22 About 6% of Discharges are from Scatter Beds after Correcting for Under and Over Estimation

23. Part II: Characteristics of Patients in Psychiatric Units and Scatter Beds

24. 24 Methods Used states that had revenue codes that accurately captured room and board Examined discharges that had a psychiatric room & board revenue code as compared to those from medical surgical rooms

25. 25 Data 12 HCUP-SID States Kentucky, Maine, Massachusetts, Nebraska, Nevada, New York, North Carolina, Pennsylvania, Tennessee, Texas, Washington, and West Virginia

26. 26 Characteristics Examined Age Gender Length of stay ICD-9-CM mental health diagnoses Existence of any secondary mental health, substance abuse, or non-mental health substance abuse ICD-9-CM diagnoses ICD-9-CM Procedures Total charges Admission source Discharge type

27. 27 Scatter Bed Discharges are More Female

28. 28 Scatter Beds Discharges Are Older

29. 29 Scatter Bed Discharges are More Medicare and Less Medicaid

30. 30 Scatter Beds Have Lower Lengths of Stay

31. 31 Scatter Beds have More Emergency Room Admissions

32. 32 Scatter Bed Discharges are More Likely to be Transferred

33. 33 Units have more schizophrenia and episodic mood disorders, scatter beds have more anxiety and other nonorganic psychosis

34. 34 Scatter beds have more secondary non-MHSA diagnoses

35. 35 Most Discharges Across Settings do not have Procedures Coded

36. 36 Limitations Data on psychiatric unit status is imperfect Data on details of clinical treatment being provided to patients in scatter beds is limited

37. 37 Conclusions Psychiatric units may play a more critical role than previously appreciated in ensuring an adequate supply of inpatient psychiatric care Scatter beds tend to be used for a short amount of time (4 days on average) and 20% of patients are transferred. More likely to be used for older Medicare patients with anxiety although 1/3 have schizophrenia or mood disorders

38. Policy Implications There are no U.S. policies to regulate, monitor, or create incentives for adequate access to psychiatric beds across the country This may need to be addressed to ensure adequate access to inpatient care Additionally, need to consider how and whether psychiatric units can be supplemented with good quality psychiatric care provided in hospitals without psychiatric units
