Does Admission to Medicine or Orthopaedics Impact a Geriatric Hip Patient's Hospital Length of Stay?

OBJECTIVES: The aim of our study was to determine the association between admitting service, medicine or orthopaedics, and length of stay (LOS) for a geriatric hip fracture patient. DESIGN: Retrospective. SETTING: Urban level 1 trauma center. PATIENTS/PARTICIPANTS: Six hundred fourteen geriatric hip fracture patients from 2000 to 2009. INTERVENTIONS: Orthopaedic surgery for geriatric hip fracture. MAIN OUTCOME MEASUREMENTS: Patient demographics, medical comorbidities, hospitalization length, and admitting service. Negative binomial regression used to determine association between LOS and admitting service. RESULTS: Six hundred fourteen geriatric hip fracture patients were included in the analysis, of whom 49.2% of patients (n = 302) were admitted to the orthopaedic service and 50.8% (3 = 312) to the medicine service. The median LOS for patients admitted to orthopaedics was 4.5 days compared with 7 days for patients admitted to medicine (P < 0.0001). Readmission was also significantly higher for patients admitted to medicine (n = 92, 29.8%) than for those admitted to orthopaedics (n = 70, 23.1%). After controlling for important patient factors, it was determined that medicine patients are expected to stay about 1.5 times (incidence rate ratio: 1.48, P < 0.0001) longer in the hospital than orthopaedic patients. CONCLUSIONS: This is the largest study to demonstrate that admission to the medicine service compared with the orthopaedic service increases a geriatric hip fractures patient's expected LOS. Since LOS is a major driver of cost as well as a measure of quality care, it is important to understand the factors that lead to a longer hospital stay to better allocate hospital resources. Based on the results from our institution, orthopaedic surgeons should be aware that admission to medicine might increase a patient's expected LOS. LEVEL OF EVIDENCE: Therapeutic Level III.

Healthcare reimbursement models and orthopaedic trauma: will there be change in patient management? A survey of orthopaedic surgeons.

OBJECTIVES: Healthcare reimbursement models are changing. Fee-for-service may be replaced by pay-for-performance or capitated care. The purpose of this study was to examine the potential changes in orthopaedic trauma surgery patient management based on potential shifts in policy surrounding readmission and reimbursement. METHODS: An e-mail survey consisting of 3 case-based scenarios was delivered to 375 orthopaedic surgeons. Five options for management of each case were provided. Each of the 3 cases was presented in 3 different healthcare settings: scenario A, our current healthcare setting; scenario B, in which 90-day reoperation or readmission would not be reimbursed; and scenario C, in which a capitated healthcare structure paid a fixed amount per patient. RESULTS: The response rate was 40.3% with 151 surgeons completing the survey. A 71.1% of the respondents were in private practice settings, whereas 28.3% were in academic centers. In each case, there was significant increase in the respondents' choice to transfer patients to tertiary care centers under both the capitated and penalization systems as compared with the current fee-for-service model. CONCLUSIONS: This survey is the first of its kind to demonstrate through case-based scenarios that a healthcare system with readmission penalties and capitated reimbursement models may lead to a significant increase in transfer of complex orthopaedic trauma patients to tertiary care centers. Physicians should be encouraged to continue evidence-based medicine instead of making decisions due to finances, and other avenues of healthcare savings should be explored to decrease patient transfer rates with healthcare changes.

Stress hyperglycemia and surgical site infection in stable nondiabetic adults with orthopedic injuries.

BACKGROUND: Hyperglycemia in nondiabetic patients outside the intensive care unit is not well defined. We evaluated the relationship of hyperglycemia and surgical site infection (SSI) in stable nondiabetic patients with orthopedic injuries. METHODS: We conducted a prospective observational cohort study at a single academic Level 1 trauma center over 9 months (Level II evidence for therapeutic/care management). We included patients 18 years or older with operative orthopedic injuries and excluded patients with diabetes, corticosteroid use, multisystem injuries, or critical illness. Demographics, medical comorbidities (American Society of Anesthesiologists class), body mass index, open fractures, and number of operations were recorded. Fingerstick glucose values were obtained twice daily. Hyperglycemia was defined as a fasting glucose value greater than or equal to 125 mg/dL or a random value greater than or equal to 200 mg/dL on more than one occasion before the diagnosis of SSI. Glycosylated hemoglobin level was obtained from hyperglycemic patients; those with glycosylated hemoglobin level of 6.0 or greater were considered occult diabetic patients and were excluded. SSI was defined by a positive intraoperative culture at reoperation within 30 days of the index case. RESULTS: We enrolled 171 patients. Of these 171, 40 (23.4%) were hyperglycemic; 7 of them were excluded for occult diabetes. Of the 164 remaining patients, 33 were hyperglycemic (20.1%), 50 had open fractures (6 Type I, 22 Type II, 22 Type III), and 12 (7.3%) had SSI. Hyperglycemic patients were more likely to develop SSI (7 of 33 [21.2%] vs. 5 of 131 [3.8%], p = 0.003). Open fractures were associated with SSI (7 of 50 [14%] vs. 5 of 114 [4.4%], p = 0.047) but not hyperglycemia (10 of 50 [20.0%] vs. 23 of 114 [20.2%], p = 0.98). There was no significant difference between infected and noninfected patients in terms of age, sex, race, American Society of Anesthesiologists class, obesity (body mass index > 29), tobacco use, or number of operations. CONCLUSION: Stress hyperglycemia was associated with SSI in this prospective observational cohort of stable nondiabetic patients with orthopedic injuries. Further prospective randomized studies are necessary to identify optimal treatment of hyperglycemia in the noncritically ill trauma population. LEVEL OF EVIDENCE: Therapeutic study, level III.
