Diagnosis-related Groups and Hospital Inpatient Federal Reimbursement.

To understand the complex system of reimbursement for health care services, it is helpful to have a working knowledge of the historic context of diagnosis-related groups (DRGs), as well as their utility and increasing relevance. Congress implemented the DRG system in 1983 in response to rapidly increasing health care costs. The DRG system was designed to control hospital reimbursements by replacing retrospective payments with prospective payments for hospital charges. This article explains how these payments are calculated. Every inpatient admission is classified into one of several hundred DRGs that are based on the diagnosis, complications, and comorbidities. The Centers for Medicare & Medicaid Services (CMS) assigns each DRG a weight that the CMS uses in conjunction with hospital-specific data to determine reimbursement. A population's DRGs represent the resources needed to treat the medical disorders of that population. Hospital administrators use this information to budget and plan for the future. The Affordable Care Act and other recent legislation affect medical reimbursement by altering the DRG system. Radiologic procedures in particular are affected. This legislation will give DRGs an even larger role in determining reimbursements in the coming years.

Use of an automated critical test result management system: effect on message delivery time.

Using an automated CTRM system in a radiology department leads to improved delivery of critical test results. Although a significant proportion of the improvement stems from experience, other factors likely contribute (eg, administrative support and acceptance by the medical staff). Longitudinal message documentation data was collected from 8 facilities. Data was evaluated to exclude the null hypothesis (absence of a relationship). CTRM experience (measured in days) was correlated with message delivery time (measured in hours). The goal was to evaluate the relationship between duration of experience and reduction in notification turnaround time (TAT).The inverse relationship of duration of experience with reduced TAT was highly significant, independent of other factors, even though experience only accounted for 25% of the improvement.

Failure to notify reportable test results: significance in medical malpractice.

BACKGROUND: Diagnostic physicians generally acknowledge their responsibility to notify referring clinicians whenever examinations demonstrate urgent or unexpected findings. During the past decade, clinicians have ordered dramatically greater numbers of diagnostic examinations. One study demonstrated that between 1996 and 2003, malpractice payments related to diagnosis increased by approximately 40%. Communication failures are a prominent cause of action in medical malpractice litigation. The aims of this study were to (1) define the magnitude of malpractice costs related to communication failures in test result notification and (2) determine if these costs are increasing significantly. EVALUATION: Linear regression analysis of National Practitioner Data Bank claims data from 1991 to 2009 suggested that claims payments increased at the national level by an average of $4.7 million annually (95% confidence interval, $2.98 million to $6.37 million). Controlled Risk Insurance Company/Risk Management Foundation claims data for 2004 to 2008 indicate that communication failures played a role, accounting for 4% of cases by volume and 7% of the total cost. DISCUSSION: Faile communication of clinical data constitutes an increasing proportion of medical malpractice payments. The increase in cases may reflect expectations of more reliable notification of medical data. Another explanation may be that the remarkable growth in diagnostic test volume has led to a corresponding increase in reportable results. If notification reliability remained unchanged, this increased volume would predict more failed notifications. CONCLUSIONS: There is increased risk for malpractice litigation resulting from diagnostic test result notification. The advent of semiautomated critical test result management systems may improve notification reliability, improve workflow and patient safety, and, when necessary, provide legal documentation.
