RESUMO
OBJECTIVES: Although more than 1.8 million people survive snakebite envenomation each year, their recovery is understudied. Obtaining long-term follow-up is challenging in both high- and low-resource settings. The Patient-Specific Functional Scale (PSFS) is an easily administered, well-accepted patient-reported outcome that is validated for assessing limb recovery from snakebite envenomation. We studied whether the PSFS is valid and reliable when administered by telephone. METHODS: This is a secondary analysis of data from a randomized clinical trial. We analyzed the results of PSFS collected in-person on days 3, 7, 14, 21, and 28 and by telephone on days 10, 17, and 24. We assessed the following scale psychometric properties: (a) content validity (ceiling and floor effects), (b) internal structure and consistency (Cronbach's alpha), and (c) temporal and external validity using Intraclass Correlation Coefficient (ICC). Temporal stability was assessed using Spearman's correlation coefficient and agreement between adjacent in-person and telephonic assessments with Cohen's kappa. Bland Altman analysis was used to assess differential bias in low and high score results. RESULTS: Data from 74 patients were available for analysis. Floor effects were seen in the early post-injury time points (median: 3 (IQR: 0, 5) at 3 days post-enrollment) and ceiling effects in the late time points (median: 9 (IQR: 8, 10). Internal consistency was good to excellent with both in-person (Cronbach α: 0.91 (95%CI 0.88, 0.95)) and telephone administration (0.81 (0.73, 0.89). Temporal stability was also good (ICC: 0.83 (0.72, 0.89) in-person, 0.80 (0.68, 0.88) telephone). A strong linear correlation was found between in-person and telephone administration (Spearman's ρ: 0.83 (CI: 0.78, 0.84), consistency was assessed as excellent (Cohen's κ 0.81 (CI: 0.78, 0.84), and Bland Altman analysis showed no systematic bias. CONCLUSIONS: Telephone administration of the PSFS provides valid, reliable, and consistent data for the assessment of recovery from snakebite envenomation.

BACKGROUND: Helicopter emergency medical services improve survival in some injured patients but current utilization leads to significant overtriage with considerable numbers of transported patients discharged home from the emergency department or found to have non-time-sensitive injuries. Current triage models for utilization are complex and untested. METHODS: Data from a state trauma registry were reviewed from 1987 to 1993 and from 2013 to 2015 and compared. Data from 2013 to 2015 were analyzed for field information found to influence mortality and a model for low mortality-risk patients designed. RESULTS: Indexed to population, a major increase in numbers of injured patients transported directly to designated trauma centers (39.849-167.626/100,000/year) occurred with an increased portion transported by helicopter emergency medical services from 7.28% to 9.26%. A simple triage tool to predict low mortality rates was designed utilizing results from logistic regression. Nongeriatric adult patients (age, 16.0-69.9 years) with a blunt injury mechanism, normal Glasgow Coma Scale motor score, pulse rate of 60 bpm to 120 bpm and respiratory rate of 10 breaths per minute to 29 breaths per minute are at low risk for mortality. Cost for helicopter transportation was substantially higher than ground transportation based on available data. Cost differentials in transport mode increased patient financial risk when helicopter transportation was utilized. CONCLUSION: Implementing a simple decision tool designating nongeriatric adult patients with a blunt injury mechanism, normal Glasgow Coma Scale motor score, systolic blood pressure greater than 90 mm Hg, pulse rate of 60 bpm to 120 bpm, and respiratory rate of 10 breaths per minute to 29 breaths per minute to ground transportation would result in substantial savings without an increase in mortality and reduce risk of patient financial harm. LEVEL OF EVIDENCE: Prognostic/Epidemiological study, level IV. Economic and value based evaluation, level IV.

BACKGROUND: In 1999, a Level I Trauma Center committed significant resources for development, recruitment of trauma surgeons, and call pay for subspecialists. Although this approach has sparked a national ethical debate, little has been published investigating efficacy. This study examines the price of commitment and outcomes at a Level I Trauma Center. METHODS: Direct personnel costs including salary, call pay, and personnel expenses were analyzed against outcomes for two periods defined as PRE (1994-1999) and POST (2000-2005). Patient care costs and 1999 to 2000 transition data were excluded. Demographics, outcomes, and direct personnel costs were compared. Significant mortality reductions stratified by age and injury severity score (ISS) were used to calculate lives saved in relation to direct personnel costs. Student's t test and chi were used (significance *p < 0.05). RESULTS: In the PRE period, there were 7,587 admissions compared with 11,057 POST. There were no significant differences PRE versus POST for age (41.4 +/- 24.4 years vs. 41.3 +/- 24.9 years), gender (62.4% vs. 63.7% male), mechanism of injury (11.5% vs. 11.8% penetrating), and percent intensive care unit admissions (30.1 vs. 29.9). Significant differences were noted for ISS (10.5 +/- 9.7 vs. 11.6 +/- 10.1*), percent admissions with ISS >or=16 (18.5 vs. 27.3*), and revised trauma score (10.8 +/- 2.8 vs. 10.7 +/- 2.8*). Both the average length of stay (6.8 +/- 8.8 vs. 6.5 +/- 9.8*) and percent mortality for ISS >or=16 (23 vs. 17*) were reduced. When mortality was stratified by both age and ISS, significant reductions were noted and a total of 173 lives were saved as a result. However, direct personnel costs increased from $7.6 million to $22.7 million. When cost is allocated to lives saved; the cost of a saved life was more than $87,000. CONCLUSIONS: Resources for program development, including salary and call pay, significantly reduced mortality. Price of commitment: $3 million per year. The cost of a saved life: $87,000. The benefit: 173 surviving patients who would otherwise be dead.

BACKGROUND: The cost of care in elderly (ELD) trauma patients is high compared with younger patients, but the association between age and reimbursement relative to cost is less clear. The purpose of this study was to explore the relationship between total costs (TC) and reimbursement in young (YNG) and ELD trauma patients. METHODS: The National Trauma Registry of the American College of Surgeons was queried for patients admitted to a level I trauma center between January 2002 and December 2004. YNG patients (18-64 years) were compared with ELD patients (> or =65 years) for mechanism of injury, Injury Severity Score, and outcome variables. Data obtained from the hospital cost accounting system included TC, total payment, and net margin (P-L). Virtually, all patients were reimbursed based on the fixed diagnostic-related group payment. RESULTS: There were 641 ELD and 3,470 YNG patients included in the study. ELD patients were more commonly injured via a blunt mechanism than the YNG patients (97% vs. 83%; p < 0.001). The ELD were more severely injured (Injury Severity Score 14.9 +/- 10.8 vs. 13.3 +/- 10.9), developed more complications (54% vs. 34%), and died more frequently (17% vs. 4.7%; all p < 0.05). TC for the ELD were significantly higher than the YNG ($20,788.92 +/- $28,305.54 vs. $19,161.11 +/- $30,441.56; p = 0.02). Total payment ($20,049.75 +/- $29,754.52 vs. $16,766.14 +/- $31,169.15) and P-L (-$739.18 +/- $17,207.84 vs. -$2,294.98 +/- $22,309.51; both p < 0.05) were significantly better for the ELD cohort. However, a financial loss was realized for all patients with trauma. CONCLUSION: When compared with YNG trauma patients, reimbursement in the ELD appears favorable. However, compensation via diagnostic-related group payment fails to cover costs even in the ELD. Reimbursement for all patients with trauma is suboptimal and needs to be improved.

BACKGROUND: Abrupt cessation of chronic drinking patterns places hospitalized patients at risk for alcohol withdrawal syndrome (AWS). The purpose of this study was to investigate the effect of AWS on length of stay, morbidity, mortality, and cost in low injury acuity trauma patients. METHODS: A retrospective review of the National Trauma Registry of the American College of Surgeons database from July 1999 to February 2004 was performed. All patients 15 years or older admitted to our Level I trauma center with an Injury Severity Score (ISS) <16 were included. AWS patients were compared with those without AWS. Demographics, mechanism of injury (MOI), ISS, revised trauma score, Glasgow Coma score, hospital course, morbidity, requirement of additional procedures, mortality, and cost were compared. Analysis was done with chi2 test and Student's t test. A p value of < or =0.05 determined significance. RESULTS: Of 6,431 patients, 55 (0.9%) developed AWS. AWS patients were likely men (p < 0.001); had a higher ISS (p = 0.001) and lower Glasgow Coma score (p = 0.01); had more ventilator days (p = 0.008), intensive care unit days (p < 0.0001), and hospital days (p < 0.0001); suffered more complications, including respiratory failure (p < 0.0001), pneumonia (p < 0.0001), urinary tract infection (p = 0.0005), sepsis (p < 0.0001), tracheostomy (p < 0.0001), and percutaneous endoscopic gastrostomy (p < 0.0001); and had higher cost (p < 0.0001). Mortality was similar (p = 0.38) among groups. CONCLUSIONS: Low injury acuity patients with AWS have increased morbidity, leading to increased hospital stay and cost. To allow minor injuries to remain minor problems, the best modality to identify patients at risk and to achieve AWS prophylaxis require further investigation.

BACKGROUND: The effect of resident work-hour restriction on patient outcome remains controversial. METHODS: Demographic data, mechanism of injury, length of hospital stay length of intensive care unit (ICU) stay, ventilator days, mortality, and complication data were prospectively collected for 11 months before and 11 months after institution of a rotating night-float system. Seven attending surgeons reviewed all complications and categorized each as preventable, potentially preventable, or nonpreventable. RESULTS: Both study periods were comparable with respect to demographic data, mean Injury Severity Score, mechanism of injury, and admissions. Limitation of resident work hours had no effect on length of hospital or ICU stay, ventilator days, or mortality. Work-hour restrictions did not increase or decrease the total number of complications nor did it alter the distribution of those determined to be preventable or potentially preventable. CONCLUSIONS: Resident work-hour restrictions were not associated with significant improvement or deterioration in patient outcome.
