A computer education program to improve physician awareness of rehabilitation hospital charges

OBJECTIVE: To quantify physician knowledge of hospital charges and determine if computer fiscal feedback would improve physician awareness of hospital charges. DESIGN: Comparison of physicians' knowledge of hospital charges before and 6 months after the instigation of a computer feedback educational program. PARTICIPANTS AND SETTING: All physicians (attendings, residents, and fellows) at a large academic rehabilitation hospital. INTERVENTION: After surveying physicians' knowledge of hospital charges, the billing fees for some items were placed on the computer ordering menu so that these charges were viewed when orders were made by physicians. MAIN OUTCOME MEASURES: Error in physician charge estimates before and after computer education program, and physician confidence in charge estimates. RESULTS: The baseline survey found that physicians had poor awareness of hospital charges, regardless of ordering frequency, relative charge for the item, or physician experience. Physicians expressed little confidence in their knowledge of the charges and were twice as likely to underestimate than to overestimate charges. Six months after the implementation of a computer feedback educational program, improvement was seen in the awareness of hospital charges for all imaging studies and most laboratory tests. Fiscal awareness of items that had not been included in the computer feedback also showed some small improvement. Physicians' confidence in their knowledge of fees improved. Physicians indicated the program was beneficial and should be expanded to include fiscal information on more services. CONCLUSIONS: Immediate computer feedback of hospital charges improves physicians' fiscal awareness and may lead to their practice of more cost-efficient medicine.     

Behavioral compliance with dialysis prescription in hemodialysis patients

The relationship between compliance and outcome is poorly understood, partially because there has been no gold standard for measuring compliance in hemodialysis patients. To investigate interrelationships between psychological, medical, and compliance factors, hemodialysis (HD) patients were studied with the Beck Depression Inventory, and a subset, the Cognitive Depression Index, the Perception of Illness Effects scale, and the Multidimensional Scale of Perceived Social Support. Behavioral compliance was measured in three ways: (1) percent time compliance (signifying "shortening behavior"); (2) percent attendance (signifying "skipping behavior) (3) percent total time compliance, assessing patients' time on dialysis normalized for prescribed time, including all shortenings and absences. Standard compliance indicators (predialysis serum potassium and phosphorus concentrations and interdialytic weight gain) were also analyzed. The patients' mean Beck Depression Inventory was in the range of mild depression. The prevalence of depression was 25.5%. Both depression indices correlated with Perception of Illness Effects scale scores. In general, social support was related to both measures of depression and perception of illness effects. Total time compliance was 95.8 +/- 5.0%. Younger patients were more likely to skip treatments compared with older patients. Time compliance comprised a wide spectrum, with most patients relatively compliant, whereas a small proportion received far less than their prescribed dialysis. Skipping and shortening behaviors did not correlate, suggesting that these constitute two separate types of noncompliant behaviors. Time compliance parameters did not correlate with potassium levels or interdialytic weight gain, but did correlate with phosphorus levels. Interrelationships between behavioral compliance measures and other parameters varied between units and patients of different gender. Finally, behavioral compliance patterns were stable over months in patients.(ABSTRACT TRUNCATED AT 250 WORDS)     

The effect of Medicare's payment system for rehabilitation hospitals on length of stay, charges, and total payments

BACKGROUND: Medicare's system for the payment of rehabilitation hospitals is based on limits derived from a hospital's average allowable charges per patient discharged during a base year. Thereafter, payments are capped but hospitals receive incentive payments if charges per patient are reduced in succeeding years. We hypothesized that per-patient charges would increase during the base year and then decrease in subsequent years. Hospitals would thus have higher reimbursement limits and receive incentive payments for reducing their charges. METHODS: We analyzed Medicare claims data for 190,921 discharges from 69 rehabilitation hospitals from 1987 through 1994. We compared total charges, length of stay, and interim payments before, during, and after each hospital's base year. RESULTS: After we controlled for inflation and temporal and seasonal trends, mean charges per patient discharged increased from $25,131 for patients discharged before the base year to $32,167 for patients discharged in the base year (a 28 percent increase, P<0.001) and the mean length of stay increased from 22.1 to 26.7 days (a 21 percent increase, P<0.001). After the base year, mean charges decreased to $29,307 (a 9 percent decrease) and the mean length of stay decreased to 24.0 days (a 10 percent decrease) (P<0.001 for both comparisons). Analysis of data on patients according to diagnosis -- for example, spinal cord injury, brain injury, stroke, amputations and deformities, hip fracture, and arthritis and joint disorders -- showed similar findings for each, with increases in charges and length of stay in the base year, followed by smaller reductions thereafter. For-profit hospitals had greater increases than nonprofit hospitals in their per-patient charges (mean increase, $7,434 vs. $2,929; P<0.001) and length of stay (mean increase, 4.6 vs. 2.3 days, P<0.001) during the base year. CONCLUSIONS: Although Medicare's reimbursement system for rehabilitation hospitals put an upper limit on total payments, its design was associated with substantial extra costs, including significantly increased payments to hospitals and doctors and increased numbers of hospital days for the average patient.     

The PEN-Ivory project: exploring user-interface design for the selection of items from large controlled vocabularies of medicine

OBJECTIVE: To explore different user-interface designs for structured progress note entry, with a long-term goal of developing design guidelines for user interfaces where users select items from large medical vocabularies. DESIGN: The authors created eight different prototypes of a pen-based progress-note-writing system called PEN-Ivory. Each prototype allows physicians to write patient progress notes using simple pen-based gestures such as circle, line-out, and scratch-out. The result of an interaction with PEN-Ivory is a progress note in English prose. The eight prototypes were designed in a principled way, so that they differ from one another in just one of three different user-interface characteristics. MEASUREMENTS: Five of the eight prototypes were tested by measuring the time it took 15 users, each using a distinct prototype, to document three patient cases consisting of a total of 63 medical findings. RESULTS: The prototype that allowed the fastest data entry had the following three user-interface characteristics: it used a paging rather than a scrolling form, it used a fixed palette of modifiers rather than a dynamic "pop-up" palette, and it made available all findings from the controlled vocabulary at once rather than displaying only a subset of findings generated by analyzing the patient's problem list. CONCLUSION: Even simple design changes to a user interface can make dramatic differences in user performance. The authors discuss possible influences on performance, such as positional constancy, user uncertainty and system anticipation, that may contribute significantly to the effectiveness of systems that display menus of items from large controlled vocabularies of medicine.     

Transition to a computer-based record using scannable, structured encounter forms

OBJECTIVE: To evaluate the quality of documentation and user satisfaction with a structured documentation system for pediatric health maintenance encounters, using scanned paper-based forms to generate an electronic medical record. DESIGN: (1) A retrospective medical record review comparing 16 structured (ST) records with 16 contemporaneously created unstructured records, (2) a questionnaire evaluation of user satisfaction, and (3) an electronic records review of patients seen 1 year following the full implementation of the system to evaluate persistence of the effect. SETTING: The Yale-New Haven Hospital Pediatric Primary Care Center, New Haven, Conn, an inner-city clinic in an academic center. PARTICIPANTS: (1) A random sample of 16 health maintenance records completed by first- and second-year residents in February 1996 matched for patient's age and provider training level with 16 contemporaneously documented visits, (2) 16 of 18 pediatric level 1 residents and 14 of 16 pediatric level 2 residents who completed questionnaires, and (3) all electronic records of health maintenance visits during February 1997. MAIN OUTCOME MEASURES: The number of data elements documented and the percentage of records that record specific components of the health maintenance encounter. User satisfaction was specified on a Likert scale. RESULTS: Overall, residents in the ST records group documented more data elements per visit than did those in the unstructured records group. The number of developmental items documented was 11.5 per visit in the ST records group and 4.8 per visit in the unstructured records group (P = .004). Likewise, anticipatory guidance was more thoroughly documented in the ST records group--8.3 items per visit vs 2.5 items per visit (P < .001). Ninety percent of the users preferred the ST records. One year after the adoption of the ST recording system, high levels of thoroughness persisted. CONCLUSIONS: Structured, scannable encounter forms can facilitate documentation of patient care and are well accepted by users. They can provide an effective mechanism to ease the transition to a computer-based patient record.     

The Maudsley Addiction Profile (MAP): a brief instrument for assessing treatment outcome

AIM: To develop a brief, multi-dimensional instrument for assessing treatment outcome for people with drug and/or alcohol problems. The Maudsley Addiction Profile (MAP) is the first instrument to be developed in the United Kingdom for this purpose. DESIGN: Field testing with quota-recruitment of problem drug users and problem alcohol users in treatment with researcher and clinician-administered test-retest interviews. SETTING: Two community and two inpatient services at the Bethlem Royal and Maudsley Hospital, London. PARTICIPANTS: Subjects (160 drug users and 80 alcohol users) interviewed by eight interviews (four researchers and four clinicians), each of whom interviewed 30 subjects on two occasions. MEASURES: Sixty items across substance use, health risk, physical/psychological health and personal/social functioning domains. FINDINGS: Average completion time of the MAP was 12 minutes. The questionnaire was acceptable to a majority of subjects and performed well with both researcher and clinician interviewers. Internal reliability and feasible concurrent validity assessments of the scales and items were highly satisfactory. Test-retest reliability was good, average intraclass correlation coefficients across eight substances were 0.94 and 0.81 across health risk, health problems, relationship conflict, employment and crime measures. CONCLUSIONS: The MAP can serve as a core research instrument with additional outcome measures added as required. The collection of a set of reliable quantitative measures of problems among drug and alcohol users by research or treatment personnel for outcome evaluation purposes need not be time-consuming.
