Introduction And Hypothesis: Enhanced recovery programs (ERPs) are evidence-based protocols designed to improve functional rehabilitation after surgery. ERPs have gained widespread acceptance in many surgical disciplines, and their use leads to significant improvements in patient outcomes while reducing hospital length of stay (LOS). There remains a paucity of data on the use of ERPs in benign gynecologic surgery.

Purpose: To develop a Korean version of the Functional Assessment of Cancer Therapy (FACT)-Vanderbilt Cystectomy Index (VCI) from the original English version, with subsequent linguistic validation in Korean patients who underwent radical cystectomy with urinary diversion.

Materials And Methods: Translation and linguistic validation were carried out between January and May of 2013, which consisted of the following stages:(1) permission for translation;(2) forward translation;(3) reconciliation;(4) backward translation;(5) cognitive debriefing and(6) final proof-reading.

Results: During the forward translation phases,word as such as "bother","spend time", "support", "coping" and "concern" were adjusted to be more comprehensible to the target population.

Purpose: Severe hyperkalemia leads to significant morbidity and mortality if it is not immediately recognized and treated. The concentration of potassium (K⁺) in the serum increases along with deteriorating renal function. The use of point-of-care K⁺ (POC-K⁺) in chronic kidney disease (CKD) could reduce the time for an accurate diagnosis and treatment, saving lives.

Purpose: Cardiopulmonary resuscitation (CPR) is commonly performed in high-risk, high intensity situations and is therefore a good procedure around which to develop and implement safety culture strategies in the hospital. The purpose of this study was to evaluate the impact of a hospital-wide quality improvement program on the management of sudden cardiac arrests by assessing healthcare providers' attitudes towards patient safety.

Materials And Methods: This study was designed as a prospective cohort study at a single academic medical center.

Purpose: The severity of a stroke cannot be described by widely used prehospital stroke scales. We investigated the usefulness of the Kurashiki Prehospital Stroke Scale (KPSS) for assessing the severity of stroke, compared to the National Institutes of Health Stroke Scale (NIHSS), in candidate patients for intravenous or intra-arterial thrombolysis who arrived at the hospital within 6 hours of symptom onset.

Materials And Methods: We retrospectively analyzed a prospective registry database of consecutive patients included in the Emergency Stroke Therapy program.

Purpose: Since the 1990s, it has been well known that orchiopexies should be performed by no later than 2 years of age. Nevertheless, studies from other countries report a substantial number of delayed orchiopexies. On the basis of an analysis of a tertiary care hospital database, we aimed to investigate the incidence of delayed orchiopexies performed in patients after 5 years of age and to understand the causes of such delays and the possible consequences.

The causes of hemolysis, elevated liver enzymes, and low platelet count (HELLP) syndrome or hepatic hemorrhage as a serious complication of HELLP are not known. Although spontaneous hepatic rupture associated with HELLP syndrome is a rare complication of pregnancy, hepatic rupture results in life-threatening complications. The cornerstone of prognosis is early diagnosis.

Background: Despite the usefulness of the Cincinnati Prehospital Stroke Scale (CPSS) for rapid recognition of acute stroke, its ability to assess stroke severity is unclear. We investigated the usefulness of CPSS for assessment of stroke severity by comparing CPSS and National Institutes of Health Stroke Scale (NIHSS) scores in patients who were candidates for thrombolytic therapy at hospital admission within 6 hours of symptom onset.

Methods: We conducted a retrospective analysis of a prospective registry database of consecutive patients included in the brain salvage through emergency stroke therapy program.

Background: In real cardiopulmonary resuscitation (CPR), noise can arise from instructional voices and environmental sounds in places such as a battlefield and industrial and high-traffic areas. A feedback device using a flashing light was designed to overcome noise-induced stimulus saturation during CPR. This study was conducted to determine whether 'flashlight' guidance influences CPR performance in a simulated noisy setting.

Objective: There has been little investigation on the appropriateness of the hand position suggested by various guidelines in paediatric cardiopulmonary resuscitation (CPR). We aimed to identify anatomical structures underneath the chest compression landmarks and tried to find the proper hand position using computed tomography (CT) images for more effective paediatric CPR.

Patients And Methods: This study included a total of 181 paediatric patients who were admitted to Severance Hospital and underwent CTs of chest.
