Utility of repeat head computed tomography after mild head trauma: influence on short- and long-term prognosis and health-related quality of life.

The aim of this study was to investigate the utility of repeat head CT in a large population of patients with non-isolated blunt mild head trauma (MTBI), especially in the presence of intracranial injury. This is a study of a cohort of 478 non-isolated MTBI patients admitted to the High Dependency Unit of the Emergency Department of the University-Hospital of Florence from July 2008 to December 2013. Results of initial and subsequent head CT scans, and indications for repeat head CT scan (routine vs. neurologic change) were recorded. The study population was divided into two subgroups: 28 (6 %) patients with neurological change or persistently reduced GCS (group GCS-) and 450 (94 %) patients with normal or improving GCS (group GCS+). After 6 months from the event, a telephone interview using SF12 questionnaire was conducted. Among GCS- patients, the admission CT scan showed intracranial lesions (ICI) in 16 (57 %) patients; only two patients had a TBI-related neurosurgical intervention. Among GCS+ patients, the first CT scan showed an ICI in 133 patients; in a significant proportion of patients with ICI at the first CT scan, the injury worsened (40/133, 30 %, p < 0.0001). However, no GCS+ patient had any neurosurgical intervention. We observed a significant reduction in both MCS and PCS scores after the injury compared with the previous period. The number of repeat CT scan was high in patients who presented ICI at the first CT scan; however, no patient with ICI and normal or improving GCS score needed a neurosurgical intervention.

Quality of life after mild to moderate trauma.

INTRODUCTION: To evaluate potential reduction in health-related quality of life (HRQOL) after a mild to moderate trauma. MATERIALS AND METHODS: Follow-up study of a cohort of 153 trauma patients admitted to the High Dependency Unit of the Emergency Department of the University-Hospital of Florence from July 2008 to February 2012. After 6 months from the event, a telephone interview using the Physical (PCS) and Mental (MCS) Health Composite Score (SF12) was conducted. Patients reported their HRQOL both at present and before trauma. Scores ≥ 50 represent no disability; 40-49, mild disability; 30-39, moderate disability; and below 30, severe disability. RESULTS: Before the event 143 (93%) subjects reported a normal PCS and MCS. After the events, a significantly lower proportion of patients maintained a normal PCS and MCS values (52 and 68%, all p<0.01). One, two, three and four PCS items worsened in 14%, 15%, 18% and 38% of the study population, while one, two, three or four MCS dimensions worsened in 12%, 19%, 19% and 24%. We identified 109 subjects (N+), which showed normal PCS and MCS values before trauma, in the absence of any pre-existing medical condition. After the event, we observed a significant PCS (before: 54, standard deviation, SD 6; after 43, SD 11, p<0.0001) and MCS (before: 55, SD 7; after 47, SD 11, p<0.0001) worsening among N+ subjects. Distribution across the four disability categories was 52, 24, 17 and 6% for MCS score and 38, 25, 27 and 11% for PCS score: overall 8 (7%) patients reported a moderate disability and 5 (5%) reported a severe disability in both dimensions. Compared with subjects with preserved values, patients with an abnormal (<39) HRQOL were older, showed a higher prevalence of female gender and pre-existing medical conditions and a worst Sequential Organ Failure Assessment score. An advanced age (OR 1.033, 95% CI 1.010-1.057, p=0.005) and a higher SOFA T1 score (OR 1.500, 95% CI 1.027-2.190, p=0.036) were independently associated with a worsening PCS. CONCLUSIONS: After a mild trauma, we evidenced a relevant reduction in HRQOL; an advanced age and a higher degree of organ dysfunction were independently associated with HRQOL deterioration.

Prognosis and health-related quality of life in elderly patients after a mild to moderate trauma.

The aims of this study were to compare outcome after a mild to moderate trauma in three subgroups of patients of increasing age (A1: <50, A2: 50-74, A3: >74 years) and to assess potential health-related quality of life (HRQOL) impairment. This is a follow-up study of a cohort of 418 trauma patients admitted to the High Dependency Unit of the Emergency Department of the University Hospital of Florence from July 2008 to February 2012. Six months after the event, a telephone interview using the Physical component summary (PCS) and Mental component summary (MCS) Health Composite Score (SF12) was conducted. Patients reported their QOL both at present and before trauma. In-hospital mortality was 10 of 418 (2.3 %); overall mortality was 27 of 244 (11 %) patients found at follow-up. No death was observed among A1 patients; overall mortality was (6/76) 7 % in A2 and (21/71) 30 % in A3 patients (p < 0.05 A1 vs A2, A1 vs A3 and A2 vs A3). Before the event, respectively, 94 and 96 % patients reported a normal MCS and PCS score (>39); after the event, the proportion of patients with a normal score value was significantly lower (MCS 70 %, p = 0.002; PCS 58 %, p < 0.0001). All subgroups showed a highly significant reduction in the scores' value due to the trauma. After the event, the proportion of patients with normal scores was significantly lower (all p < 0.0001, except for MCS score in A1 subgroup, who showed p = 0.013) within all subgroups. Elderly patients' prognosis was significantly worse compared with the younger counterpart; despite young patients' optimal outcome, HRQOL was uniformly reduced across all age groups.

Management of patients with acute atrial fibrillation in the ED.

BACKGROUND: Patients with acute atrial fibrillation with a history of mild structural heart disease could be considered for rhythm conversion. METHODS: Patients received intravenous flecainide, propafenone, or amiodarone on presentation and a second dose after 6 hours if atrial fibrillation persisted. No randomization was used, and drugs were given at the discretion of the treating physician. Primary end point was rhythm conversion within the first 6 hours from presentation. Secondary end points included rhythm conversion, time to rhythm conversion, and adverse drug effects within 24 hours. RESULTS: Among the 378 patients enrolled, 37 (10%) recovered sinus rhythm before therapy was given. Of the remaining 341 patients, 43 (13%) received flecainide, 187 (55%) received propafenone, and 111 (32%) received amiodarone. Baseline clinical characteristics were homogeneous among groups. Rhythm conversion was obtained in 87% of treated patients overall. Within 6 hours, the primary end point was achieved in a higher proportion in the flecainide and propafenone groups (72% and 55%, respectively) as compared with the amiodarone group (30%; P < .001). The mean time to the end point overall was shorter in the flecainide and propafenone groups (178 ± 227 and 292 ± 285 minutes, respectively) as compared with the amiodarone group (472 ± 269 minutes; P < .001). Length of in-hospital stay in the amiodarone group was significantly higher (26.1 ± 22.4 hours) compared with the flecainide and propafenone groups (8.9 ± 10.3 and 11.0 ± 13.8 hours; respectively; P = .001). No significant differences were found in adverse drug effects. CONCLUSIONS: Flecainide and propafenone achieve rhythm control in a higher proportion of patients as compared with amiodarone within a 6-hour management.
