A Comparison of the Charlson and Elixhauser Methods for Predicting Nursing Indicators in Gastrectomy with Gastric Cancer Patients.

Background: Comorbidity indices such as Charlson's (CCI) and Elixhauser's (ECI) are used to adjust the patient's care, depending on the severity of their condition. However, no study has compared these indices' ability to predict nursing-sensitive outcomes (NSOs). We compared the performance of CCI and ECI in predicting NSOs in gastric cancer patients' gastrectomy. Methods: Gastric cancer patients with gastrectomy, aged 19 years or older and admitted between 2015 and 2016, were selected from the Korea Insurance Review and Assessment Service database. We examined the relationships between NSOs and CCI or ECI while adjusting patient and hospital characteristics with logistic regression. Results: The ECI item model was the best in view of the C-statistic and Akaike Information Criterion for total NSO, physiologic/metabolic derangement, and deep vein thrombosis, while the Charlson item model was the best for upper gastrointestinal tract bleeding. For the C-statistic, the ECI item model was the best for in-hospital mortality, CNS complications, shock/cardiac arrest, urinary tract infection, pulmonary failure, and wound infection, while the CCI item model was the best for hospital-acquired pneumonia and pressure ulcers. Conclusions: In predicting 8 of 11 NSOs, the ECI item model outperformed the others. For other NSOs, the best model varies between the ECI item and CCI item model.

Comparison of Bleeding, Hematoma, Pain, and Discomfort After Bone Marrow Examination With or Without Sandbag Compression.

PURPOSE: A safe and effective hemostatic care is necessary after bone marrow examination to minimize bleeding, pain, and discomfort. However, a standardized hemostatic care protocol following bone marrow examination has not been established. The purpose of this study was to investigate the differences in bleeding, hematoma, pain, and discomfort by the hemostatic method used following bone marrow examination. METHODS: This study was carried out with a pre-test/post-test nonequivalent control group design. Sixty-four patients undergoing bone marrow examination at the hemato-oncology ward in a tertiary hospital in South Korea were assigned to an intervention (n = 30) and comparison group (n = 34). The intervention group was treated using a compression dressing alone, while the comparison group received a compression dressing followed by sandbag compression. Both groups received two hours of bedrest. Bleeding, hematoma, pain, and discomfort were measured at one and two hours after the biopsy. RESULTS: No significant differences in the occurrence of bleeding between the groups at one and two hours after bone marrow examination were observed, and no participant developed hematoma. The intervention group had significantly lower pain than the comparison group two hours after the bone marrow examination as well as lower discomfort one hour and two hours after the bone marrow examination (p < .05). CONCLUSION: Applying only compression dressing after a bone marrow examination is effective in reducing pain and discomfort without measurable differences in bleeding and hematoma, suggesting that compression dressings alone could be effective in lowering pain and discomfort following bone marrow examination.

Effects of Video-Based Information Provision Using a Smart Pad on Patients Undergoing Bone Marrow Biopsy.

The purpose is to determine the effect of video-based information provision using a smart pad on uncertainty, anxiety, physiological parameters, pain, and educational satisfaction among patients hospitalized for a bone marrow biopsy. This study was done with a pre-/posttest nonequivalent control group design. The subjects were 65 patients in the hematology-oncology ward of a university hospital in Cheongju, South Korea, who underwent a bone marrow biopsy between August 2017 and May 2018. Thirty volunteers were allocated to the control group and 35 volunteers to the intervention group. The experimental group showed significantly lower uncertainty and significantly greater satisfaction with education than did the control group. No significant difference was observed in anxiety, systolic and diastolic blood pressure, pulse, and pain. Video-based information provision using a smart pad was effective for lowering uncertainty among patients receiving a bone marrow biopsy, as well as for boosting their sense of educational satisfaction.

The association between nurse staffing levels and paediatric nursing-sensitive outcomes in tertiary hospitals.

AIM: This study aimed to explore the association between paediatric nursing-sensitive outcomes and nurse staffing levels. BACKGROUND: Although previous studies have reported an association between low nursing-sensitive outcomes and high nurse staffing levels in adult populations, there are few studies on paediatric nursing-sensitive outcomes. METHODS: This study used electronic Health insurance review and assessment data for all children under 18 years old admitted at 46 tertiary hospitals in Korea between 2013 and 2014. Multiple logistic regression was used to examine relationships among nurse staffing levels and 11 paediatric nursing-sensitive outcomes. RESULTS: Nurse staffing levels had a clear relationship with the occurrence of lower respiratory tract infection and gastrointestinal infection. Five paediatric nursing-sensitive outcomes (pneumonia, sepsis, arrest / shock / respiratory failure, wound infection and postoperative cardiopulmonary complication) showed weak relationships with nurse staffing levels. Pressure ulcers and failure to rescue had the lowest incidences in hospitals with the lowest nurse staffing levels. CONCLUSIONS: We demonstrated evidence for the relationships of nurse staffing levels with seven paediatric nursing-sensitive outcomes. IMPLICATIONS FOR NURSING MANAGEMENT: For quality paediatric nursing care, nurse staffing improvement is required. The study results could be useful evidence for appropriateness of nursing staffing in paediatric facilities.

Impact of surgical volume on nationwide hospital mortality after pancreaticoduodenectomy.

AIM: To evaluate the impact of surgical volume on nationwide hospital mortality after pancreaticoduodenectomy (PD) for periampullary tumors in South Korea. METHODS: Periampullary cancer patients who underwent PD between 2005 and 2008 were analyzed from the database of the Health Insurance Review and Assessment Service of South Korea. A total of 126 hospitals were divided into 5 categories, each similar in terms of surgical volume for each category. We used hospital mortality as a quality indicator, which was defined as death during the hospital stay for PD, and calculated adjusted mortality through multivariate logistic models using several confounder variables. RESULTS: A total of eligible 4975 patients were enrolled in this study. Average annual surgical volume of hospitals was markedly varied, ranging from 215 PDs in the very-high-volume hospital to < 10 PDs in the very-low-volume hospitals. Admission route, type of medical security, and type of operation were significantly different by surgical volume. The overall hospital mortality was 2.1% and the observed hospital mortality by surgical volume showed statistical difference. Surgical volume, age, and type of operation were independent risk factors for hospital death, and adjusted hospital mortality showed a similar difference between hospitals with observed mortality. The result of the Hosmer-Lemeshow test was 5.76 (P = 0.674), indicating an acceptable appropriateness of our regression model. CONCLUSION: The higher-volume hospitals showed lower hospital mortality than the lower-volume hospitals after PD in South Korea, which were clarified through the nationwide database.

The relationship between hospital volume and outcome of gastrointestinal cancer surgery in Korea.

OBJECTIVES: To assess the relationship between hospital volume and in-hospital mortality of patients undergoing four surgical procedures for gastrointestinal cancers in Korea. METHODS: Using the database of the Health Insurance Review and Assessment Service, we identified 66,201 patients who underwent the four types of gastrointestinal resection during the period 2005-2006. Participating hospitals were divided into five groups according to their surgical volume. The primary outcome was in-hospital mortality, defined as death from any cause before discharge. Multivariate logistic regression analysis was performed to determine the effect of hospital volume on risk-adjusted in-hospital mortality. RESULTS: We observed a significant relationship between hospital volume and in-hospital mortality rate for patients undergoing the four types of cancer-related gastrointestinal surgeries. The in-hospital mortality rate was lower for high-volume than for low-volume hospitals after adjusting for patient characteristics. The differences between very-high-volume and very-low-volume hospitals ranged from 0.94% to 2.77% for the four procedures, with the largest difference observed for pancreatic resection (3.75% vs. 0.98%). CONCLUSION: High-volume hospitals had better short-term surgical outcome than low-volume hospitals. We confirmed the volume-outcome relationship for four cancer-related gastrointestinal resections in Korea.
