Factors associated with post-arrest withdrawal of life-sustaining therapy.
INTRODUCTION: Most successfully resuscitated cardiac arrest patients do not survive to hospital discharge. Many have withdrawal of life sustaining therapy (WLST) as a result of the perception of poor neurologic prognosis. The characteristics of these patients and differences in their post-arrest care are largely unknown.
METHODS: Utilizing the Penn Alliance for Therapeutic Hypothermia Registry, we identified a cohort of 1311 post-arrest patients from 26 hospitals from 2010 to 2014 who remained comatose after return of spontaneous circulation. We stratified patients by whether they had WLST post-arrest and analyzed demographic, arrest, and post-arrest variables.
RESULTS: In our cohort, 565 (43%) patients had WLST. In multivariate regression, patients who had WLST were less likely to go to the cardiac catheterization lab (OR 0.40; 95% CI: 0.26-0.62) and had shorter hospital stays (OR 0.93; 95% CI: 0.91-0.95). When multivariate regression was limited to patient demographics and arrest characteristics, patients with WLST were older (OR 1.18; 95% CI: 1.07-1.31 by decade), had a longer arrest duration (OR 1.14; 95% CI: 1.05-1.25 per 10min), more likely to be female (OR: 1.41; 95% CI: 1.01-1.96), and less likely to have a witnessed arrest (OR 0.65; 95% CI: 0.42-0.98).
CONCLUSION: Patients with WLST differ in terms of demographic, arrest, and post-arrest characteristics and treatments from those who did not have WLST. Failure to account for this variability could affect both clinical practice and the interpretation of research
Blunt Abdominal Trauma Patients Are at Very Low Risk for Intra-Abdominal Injury after Emergency Department Observation
<p>Introduction: Patients are commonly admitted to the hospital for observation following blunt abdominal trauma (BAT), despite initially negative emergency department (ED) evaluations. With the current use of screening technology, such as computed tomography (CT) of the abdomen and pelvis, ultrasound, and laboratory evaluations, it is unclear which patients require observation. The objective of this study was to determine the prevalence of intra-abdominal injury (IAI) and death in hemodynamically normal and stable BAT patients with initially negative ED evaluations admitted to an ED observation unit and to define a low-risk subgroup of patients and assess whether they may be discharged without abdominal/pelvic CT or observation. Methods: This was a retrospective cohort study performed at an urban level 1 trauma center and included all BAT patients admitted to an ED observation unit as part of a BAT key clinical pathway. All were observed for at least 8 hours as part of the key clinical pathway, and only minors and pregnant women were excluded. Outcomes included the presence of IAI or death during a 40-month follow-up period. Prior to data collection, low-risk criteria were defined as no intoxication, no hypotension or tachycardia, no abdominal pain or tenderness, no hematuria, and no distracting injury. To be considered low risk, patients needed to meet all low-risk criteria. Results: Of the 1,169 patients included over the 2-year study period, 29% received a CT of the abdomen and pelvis, 6% were admitted to the hospital from the observation unit for further management, 0.4% (95% confidence interval [CI], 0.1%–1%) were diagnosed with IAI, and 0% (95% CI, 0%–0.3%) died. Patients had a median combined ED and observation length of stay of 9.5 hours. Of the 237 (20%) patients who met low-risk criteria, 7% had a CT of the abdomen and pelvis and 0% (95% CI, 0%–1.5%) were diagnosed with IAI or died. Conclusion: Most BAT patients who have initially negative ED evaluations are at low risk for IAI but still require some combination of observation and CT. A subgroup of BAT patients may be safely discharged without CT or observation after the initial evaluation. [West J Emerg Med. 2011;12(4):496–504.]</p
Structural factors and best practices in implementing a linkage to HIV care program using the ARTAS model
<p>Abstract</p> <p>Background</p> <p>Implementation of linkage to HIV care programs in the U.S. is poorly described in the literature despite the central role of these programs in delivering clients from HIV testing facilities to clinical care sites. Models demonstrating success in linking clients to HIV care from testing locations that do not have co-located medical care are especially needed.</p> <p>Methods</p> <p>Data from the Antiretroviral Treatment Access Studies-II project ('ARTAS-II') as well as site visit and project director reports were used to describe structural factors and best practices found in successful linkage to care programs. Successful programs were able to identify recently diagnosed HIV-positive persons and ensure that a high percentage of persons attended an initial HIV primary care provider visit within six months of enrolling in the linkage program.</p> <p>Results</p> <p>Eight categories of best practices are described, supplemented by examples from 5 of 10 ARTAS-II sites. These five sites highlighted in the best practices enrolled a total of 352 HIV+ clients and averaged 85% linked to care after six months. The other five grantees enrolled 274 clients and averaged 72% linked to care after six months. Sites with co-located HIV primary medical care services had higher linkage to care rates than non-co-located sites (87% vs. 73%). Five grantees continued linkage to care activities in some capacity after project funding ended.</p> <p>Conclusions</p> <p>With the push to expand HIV testing in all U.S. communities, implementation and evaluation of linkage to care programs is needed to maximize the benefits of expanded HIV testing efforts</p

Long-term thrombotic recurrence after nonoperative management of Paget-Schroetter syndrome
The purpose of this study was to determine the clinical predictors associated with long-term thrombotic recurrences necessitating surgical intervention after initial success with nonoperative management of patients with primary subclavian vein thrombosis.
Sixty-four patients treated for Paget-Schroetter syndrome from 1996 to 2005 at our institution were reviewed. The standardized protocol for treatment includes catheter-directed thrombolysis, a short period of anticoagulation, and selective surgical decompression for patients with persistent symptoms. First-rib resection was performed in 29 patients (45%) within the first 3 months, with a success rate of 93%. The remaining 35 patients (55%) were treated nonoperatively and constitute this study’s population.
Of the 35 patients with successful nonoperative management, 8 (23%) developed recurrent thrombotic events of the same extremity at a mean follow-up time of 13 months after thrombolysis (range, 6-33 months). These eight patients subsequently underwent first-rib resection with a 100% success rate without further sequelae at a mean follow-up time of 51 months (range, 2-103 months). The other 27 patients remained symptom free at a mean follow-up interval of 55 months (range, 10-110 months). Bivariate analyses determined that the use of a stent during the initial thrombolysis was associated with thrombotic recurrence (
P = .05). The recurrence group was also significantly younger than the asymptomatic group (22 vs 36 years;
P = .01). Sex, being a competitive athlete, a history of trauma, whether the dominant arm was affected, time of delay to lysis, initial clot burden, response to original lysis, use of adjunctive balloons or mechanical thrombectomy devices, residual stenosis on venography, length of time on warfarin, and patency of the vein on follow-up duplex examination were all characteristics not associated with long-term recurrence after nonoperative management.
Conservative nonoperative management of primary subclavian vein thrombosis can be successfully used with acceptable long-term results. A younger age (<28 years old) and the use of a stent during initial thrombolysis are factors associated with long-term recurrent thrombosis. Younger patients should be offered early surgical decompression, and the use of stents without thoracic outlet decompression is not indicated
