The evolution of an acute care hospital unit to a DRG-exempt rehabilitation unit. A preliminary communication

The Health Care Financing Administration's decision to adopt a prospective based payment system has caused many institutions to implement new policies and practices. A recent area of interest for many hospitals has been the creation of diagnosis-related group (DRG) exempt units to maximize reimbursement practices. We analyzed changes which occurred when an eight bed acute care stroke unit (SU) was converted to a DRG exempt eight bed rehabilitation unit (RU). The time period involved was 1 1/2 months before and 1 1/2 months after the transition occurred. Analysis of data from the pre- and posttransition periods revealed that: (1) length of stay increased significantly from 11.7 to 15.3 days (P less than 0.001); (2) functional independence measure (FIM) score improvement was significantly greater (P less than 0.05) for RU patients (0.84/day) than for SU patients (0.39/day); (3) disposition to home v other facilities increased significantly from 50 to 81% (P less than 0.05); (4) the overall occupancy increased from 94 to 100% and all beds were filled with rehabilitation patients; (5) the proportion of patients with Medicare as their primary insurer was comparable before (64%) and after (67%) unit conversion; (6) gross income from rehabilitation patients increased by 43%. Indirect savings via reduction of acute hospital length of stay for Medicare patients increased total income from operation of this unit. We conclude that patients on the RU stayed longer, had greater daily improvements in functional status, and were more likely to be discharged to home. This appears to be due to a more efficient use of rehabilitation beds and a concomitant overall improvement in reimbursement to the hospital.(ABSTRACT TRUNCATED AT 250 WORDS)     

Oral health care for the patient with schizophrenia

Schizophrenia is a psychiatric disorder affecting 1%of the United States population. Conceptualizing the disorder as consisting of "positive" and "negative" symptoms has led to improved treatment modalities. Medications used in managing the "positive" symptoms have numerous systemic and orofacial adverse side effects that must be recognized by the dentist. Dental treatment strategies for the identification and management of these side effects art! described. "Negative" symptoms are responsible for chronicity of the disorder and frequently impede rehabilitation. These symptoms are potentially devastating to oral health as they impair a patient's desire and ability to invoke preventive oral hygiene. Treatment strategies to improve compliance with oral hygiene techniques are outlined. A medication specifically indicated for patients with treatment- resistent disease and marked "negative" symp toms has recently been approved for use in the United States. The systemic and orofacial adverse side effects of this medication and its influence on dental management are reviewed.     

Evaluating the capacity to work of the mentally ill

This study explored the relationship between psychiatric symptomatology and the functional capacity to work. Subjects were diagnosed using DSM-III criteria and were grouped into categories of psychotic or nonpsychotic, and disabled or nondisabled, in regard to adjudication for mental impairment from the Social Security Administration (SSA). There were significant relationships between disability status and work capacity, in the direction of better performance for the nondisabled subjects. This finding reflected concordance between the evaluation procedure used in the study and the SSA's disability determination process. There was considerable overlap in work performance among subjects, however, suggesting that a functional assessment of work capacity might improve disability determination in certain cases. Results suggested that these work assessments might be as short as one or two days.     

Use of cross-correlation function to detect patient motion during SPECT imaging

We have developed a procedure to detect patient motion during a tomographic acquisition. The method uses frame-to-frame cross-correlation functions of the summed profiles in the vertical and horizontal directions of the planar images. The quantitative output derived from examination of the variation of the change in the pixel value, corresponding to the maximum of the cross-correlation function at each view, provides an effective and nonsubjective means of performing quality control on the presence and amount of movement during a single photon emission computed tomographic scan. In contrast to cine mode and sinogram display, easy to interpret hard copy can be generated through this procedure.
