The impact of managed care and current governmental policies on an urban academic health care center.

BACKGROUND: Managed care and governmental policies have restructured hospital reimbursement. We examined reimbursement trends in trauma care to assess the impact of this market driven change on an urban academic health center. METHODS: Patients injured between January 1997 and December 1999 were analyzed for Injury Severity Score (ISS), length of hospital stay, hospital cost, payer, and reimbursement. RESULTS: Between 1997 and 1999, the volume of patients with an ISS less than 9 increased and length of stay decreased. In addition, overall cost, payment, and profit margin increased. Commercially insured patients accounted for this margin increase, because the margins of managed care and government insured patients experienced double-digit decreases. Patients with ISS of 9 or greater also experienced a volume increase and a reduction in length of stay; however, costs within this group increased greater than payments, thereby reducing profit margin. Whereas commercially insured patients maintained their margin, managed care and government insured patients did not (double- and triple-digit decreases). CONCLUSIONS: Managed care and current governmental policies have a negative impact on urban academic health center reimbursement. Commercial insurers subsidize not only the uninsured but also the government insured and managed care patients as well. National awareness of this issue and policy action are paramount to urban academic health centers and may also benefit commercial insurers.

Cytokines and the pathogenesis of nosocomial pneumonia.

BACKGROUND: Nosocomial pneumonia (NP) in injured patients is a significant clinical problem. We hypothesize that the pathogenesis of NP in injured patients involves an imbalanced cytokine response within the alveolar airspace that may inhibit effector cell function. METHODS: Proinflammatory (IL-8) and anti-inflammatory (IL-10) levels were measured in bronchoalveolar lavage (BAL) fluid from multitrauma patients on admission, 24, 48, and 72 hours post-injury and following lipopolysaccharide (LPS) induction of alveolar cells. Patients were compared based on IL-8 levels and the development of NP. RESULTS: A high level of IL-8 on admission was associated with the development of NP. In addition, levels of IL-8 were significantly greater in NP-positive patients at all time points. The IL-10 levels decreased from admission values in NP-negative patients but increased in NP-positive patients. Furthermore, a high level of IL-10 ( > 120 pg/mL) at 72 hours post-injury was associated with the development of NP. Alveolar cells from NP-positive patients produced significantly more IL-10 in response to LPS than cells from NP-negative patients. CONCLUSIONS: The pathogenesis of NP in injured patients involves an early and severe IL-8 process within the lung followed by an exaggerated IL-10 response that may inhibit effector cell function.

Hyperphosphatemia in a burn patient.

Hypophosphatemia has been observed in severely burned patients and has been associated with increased mortality. Hyperphosphatemia has rarely been described in this population. We present a burn patient with hyperphosphatemia, hypercalciuria, and suppressed parathyroid hormone level 5 months after the initial burn. The patient's presentation is most consistent with the effect of immobilization on bone and calcium metabolism.

Academic practice groups: strategy for survival.

BACKGROUND: The mission of public academic health centers (puAHC) and their affiliated practice groups (APG) focuses on teaching, research, and the clinical care of at-risk populations. Resources to accomplish this mission, however, are becoming scarce. For puAHC to survive and remain competitive, innovative strategies will need to be developed by the APG. We hypothesized that the integration of a surgical academic practice of the APG with a nonacademic integrated health care delivery system (NAIDS) in a managed care environment would benefit all involved. METHODS: A surgical academic practice was integrated with a NAIDS in a 95% managed care market. Faculty alone provided care the first year, and third-year residents were added the following year. To assess outcome, we collected benefit and cost data for the 1-year period before integration and compared them with the two, 1-year periods after integration. RESULTS: In the second year of integration, revenues from the NAIDS referrals to the puAHC and APG increased 89% and 150%, respectively. The NAIDS' general surgical and endoscopy caseload increased by 25%. Additionally, there was a 92% reduction in operating room technician cost with no increase in operating time per case. Finally, the third-year resident experienced a caseload increase of 163%. CONCLUSIONS: In an environment where resources are diminishing and managed care consists of many large NAIDS that drive referrals and revenue, the integration of a surgical academic practice with a NAIDS benefits all shareholders. Academic practice groups that develop strategies that leverage their competitive advantage will have the best chance of surviving in today's turbulent health care market.
