Decompressive Hemicraniectomy for Acute Ischemic Stroke in the US: Characteristics and Outcomes.

OBJECTIVES: Decompressive hemicraniectomy can be life-saving for malignant middle cerebral artery acute ischemic stroke (AIS). However, utilization and outcomes for hemicraniectomy in the US are not known. We sought to analyze baseline characteristics and outcomes of patients receiving hemicraniectomy for AIS in the US. MATERIALS AND METHODS: We identified adults who received hemicraniectomy for AIS, identified with validated International Classification of Disease, Ninth Revision, Clinical Modification (ICD-9) code in the Nationwide Readmissions Database 2014. We calculated 30-day readmission rates, reasons for readmission, and procedures performed. RESULTS: 2850 of 531,896 AIS patients (0.54%) received hemicraniectomy. Although patients receiving hemicraniectomy were more likely to be younger (57.0, 95% CI 56.0-58.0; vs 70.9, 95% CI 70.6-71.2; p < 0.0001) and male (40% vs 51.2% female; p<0.0001), 46.3% of patients who received hemicraniectomy were age 60 years and older. Patients 60 years or older receiving hemicraniectomy were more likely to die (29.9% vs 21.9%, p = 0.0081). Hemicraniectomy was more frequently performed at large hospitals (75.3% vs 57.7%; p < 0.0001) in urban areas (99.1% vs 90.3%; p < 0.0001) designated as metropolitan teaching hospitals (88.3% vs 63.4%; p < 0.0001). 30-day readmissions were most commonly due to infection (31.5%), non-infectious medical complications (17.7%), and surgical complications (13.8%). These readmissions were critical. CONCLUSIONS: Although hemicraniectomy is used more frequently in the treatment of younger, male, ischemic stroke patients, only half of the patients receiving hemicraniectomy in 2014 were <60 years old. Regardless of age, hemicraniectomy is a geographically segregated procedure, only being performed in large metropolitan teaching hospitals.

The rapid adoption of opportunistic salpingectomy at the time of hysterectomy for benign gynecologic disease in the United States.

BACKGROUND: Mounting evidence for the role of distal fallopian tubes in the pathogenesis of epithelial ovarian cancer has led to opportunistic salpingectomy being increasingly performed at the time of benign gynecologic surgery. Opportunistic salpingectomy has now been recommended as best practice in the United States to reduce future risk of ovarian cancer even in low-risk women. Preliminary analyses have suggested that performance of opportunistic salpingectomy is increasing. OBJECTIVE: To examine trends in opportunistic salpingectomy in women undergoing benign hysterectomy and to determine how the publication of the tubal hypothesis in 2010 may have contributed to these trends. STUDY DESIGN: This is a population-based, retrospective, observational study examining the National Inpatient Sample between January 2001 and September 2015. Women younger than 50 years who underwent inpatient hysterectomy for benign gynecologic disease were grouped as hysterectomy alone vs hysterectomy with opportunistic salpingectomy. All women had ovarian conservation, and those with adnexal pathology were excluded. Linear segmented regression with log transformation was used to assess temporal trends. An interrupted time-series analysis was then used to assess the impact of the 2010 publication of the tubal hypothesis on opportunistic salpingectomy trends. A regression-tree model was constructed to examine patterns in the use of opportunistic salpingectomy. A binary logistic regression model was then fitted to identify independent characteristics associated with opportunistic salpingectomy. Sensitivity analysis was performed in women aged 50-65 years to further assess surgical trends in a wider age group. RESULTS: There were 98,061 (9.0%) women who underwent hysterectomy with opportunistic salpingectomy and 997,237 (91.0%) women who underwent hysterectomy alone without opportunistic salpingectomy. The rate at which opportunistic salpingectomy was being performed gradually increased from 2.4% to 5.7% between 2001 and 2010 (2.4-fold increase; P<.001), predicting a 7.0% rate of opportunistic salpingectomy in 2015. However, in 2010, the rate of opportunistic salpingectomy began to increase substantially and reached 58.4% by 2015 (10.2-fold increase; P<.001). In multivariable analysis, the largest change in the performance of opportunistic salpingectomy occurred after 2010 (adjusted odds ratio, 5.42; 95% confidence interval, 5.34-5.51; P<.001). In a regression-tree model, women who had a hysterectomy at urban teaching hospitals in the Midwest after 2013 had the highest chance of undergoing opportunistic salpingectomy during benign hysterectomy (76.4%). In the sensitivity analysis of women aged 50-65 years, a similar exponential increase in opportunistic salpingectomy was observed from 5.8% in 2010 to 55.8% in 2015 (9.8-fold increase; P<.001). CONCLUSION: Our study suggests that clinicians in the United States rapidly adopted opportunistic salpingectomy at the time of benign hysterectomy following the publication of data implicating the distal fallopian tubes in ovarian cancer pathogenesis in 2010. By 2015, nearly 60% of women had undergone opportunistic salpingectomy at benign hysterectomy.

Characteristics of hospitalizations among patients receiving immune checkpoint inhibitors at a community teaching hospital.

PURPOSE: As immune checkpoint inhibitors continue to acquire new indications, it is important to understand the impact their use has on patients. This study adds to current literature by presenting an analysis of hospitalizations in this population. The primary objective was to assess the reasons for an emergency department visit or hospital admission in patients who receive immune checkpoint inhibitors. Secondary objectives included identifying the frequency of suspected or confirmed immune related adverse events, types of immune related adverse events, number of preventable admissions, duration of immunotherapy, and length of stay. METHODS: This study was a retrospective, multi-center, chart review of patients hospitalized after receiving an immune checkpoint inhibitor. The population included patients aged 18 and above who received at least one dose of an immune checkpoint inhibitor at a network facility and had a documented admission within one year following the initiation of immunotherapy. Descriptive statistics were performed along with inferential comparisons and a Poisson regression to determine if the immune checkpoint blocker or cancer type predicted admission or reason for admission. RESULTS: The 99 patients who met inclusion criteria had a total of 202 admissions. Of these patients, 56 (56.6%) had multiple admissions within the year following initiation of immunotherapy. The most common diagnoses on initial admissions were shortness of breath, pain, and pneumonia. A total of 104 admissions (51.5%) were considered potentially preventable. Suspected or confirmed immune related adverse events were identified in 15.6% of all admissions. There were no significant predictors of admissions or reason for admission. CONCLUSION: Reasons for admission in the study population were comparable to those identified in the general cancer population, with immune related adverse events being associated with a minority of both total and potentially preventable admissions.

Long-term mortality of patients discharged from the hospital after successful critical care in the ICU in Korea: a retrospective observational study in a single tertiary care teaching hospital.

BACKGROUND: The long-term outcomes of patients discharged from the hospital after successful care in intensive care unit (ICU) are not briskly evaluated in Korea. The aim of this study was to assess long-term mortality of patients treated in the ICU and discharged alive from the hospital and to identify predictive factors of mortality. METHODS: In 3,679 adult patients discharged alive from the hospital after ICU care between 2006 and 2011, the 1-year mortality rate (primary outcome measure) was investigated. Various factors were entered into multivariate analysis to identify independent factors of 1-year mortality, including sex, age, severity of illness (APACHE II score), mechanical ventilation, malignancy, readmission, type of admission (emergency, elective surgery, and medical), and diagnostic category (trauma and non-trauma). RESULTS: The 1-year mortality rate was 13.4%. Risk factors that were associated with 1-year mortality included age (hazard ratio: 1.03 [95% CI, 1.02-1.04], P < 0.001), APACHE II score (1.03 [1.01-1.04], P < 0.001), mechanical ventilation (1.96 [1.60-2.41], P < 0.001), malignancy (2.31 [1.82-2.94], P < 0.001), readmission (1.65 [1.31-2.07], P < 0.001), emergency surgery (1.66 [1.18-2.34], P = 0.003), ICU admission due to medical causes (4.66 [3.68-5.91], P < 0.001), and non-traumatic diagnostic category (6.04 [1.50-24.38], P = 0.012). CONCLUSIONS: The 1-year mortality rate was 13.4%. Old age, high APACHE II score, mechanical ventilation, malignancy, readmission, emergency surgery, ICU admission due to medical causes, and non-traumatic diagnostic category except metabolic/endocrinologic category were associated with 1-year mortality.

Changes in Total Knee Arthroplasty Utilization since the Implementation of ACA: An Analysis of Patient-Hospital Demographics, Costs, and Charges.

The Patient Protection and Affordable Care Act (PPACA) formed the Center for Medicare and Medicaid Innovation Center which has implemented experimental reimbursement models targeted at high-demand procedures to improve care quality. However, the effect of health care reform on total knee arthroplasty (TKA) procedures has not been explored. This study explores patient-hospital level demographics, inpatient costs, and charges related to TKA procedures between 2009 and 2015. The National Inpatient Sample database was utilized to identify patients who received primary TKA between January 2009 and October 2015 (4,283,387 cases). Categorical, continuous, and ordinal data were analyzed using chi-square/Fisher's exact test, t-test/analysis of variance, or Kruskal-Wallis' test, respectively. There was an increase in proportion of TKA recipients belonging to minority groups and the lowest quartile of median income (p < 0.05). There was a 1.9% increase in recipients using Medicaid as a primary payor and volume shifts from urban nonteaching toward urban teaching hospitals. There was a reduction in mean length of stay and mean inpatient costs. There were increases in hospital charges, but reductions in rates of inpatient mortality, and other postoperative complications. TKA procedures remain the most common surgical procedure; therefore, our study assessed national trends to capture the effect of PPACA. We found an increasing proportion of TKA recipients belonging to minority and low-income groups, volume shifts to urban teaching hospitals, and lower costs of care. These findings may be useful in objectively critiquing the effects of PPACA on TKA-related care.

Nationwide trends in the use of subtotal cholecystectomy for acute cholecystitis.

BACKGROUND: Subtotal cholecystectomy is a viable alternative approach to the proverbial "difficult" gallbladder. To date, only a few studies have observed the establishment of those bail-out procedures as an increasingly common surgical practice. The purpose of this study is to assess nationwide trends of subtotal cholecystectomy through evaluation of operative variables and patient- and institution-level characteristics in procedure preference. METHODS: Data were obtained from the National Inpatient Sample for the years between 2003 and 2014. Patients with acute cholecystitis were categorized based on the ninth revision International Classification of Disease Clinical Modification procedure codes for open total, laparoscopic total, open subtotal, or laparoscopic subtotal cholecystectomy. Any patient younger than 18 years of age or with a preoperative stay >1 week was excluded. Logistic regression analysis was performed to evaluate significant patient- and institution-level characteristics associated with the performance of subtotal cholecystectomy. RESULTS: A total of 290,855 patients were evaluated. During the study period, the rate of open and laparoscopic subtotal cholecystectomy sharply increased (0.10% of all cholecystectomy procedures to 0.52% and 0.12% to 0.28%, respectively). The conversion rate from laparoscopic to open total cholecystectomy decreased from 10.5% to 7.6%. Subtotal cholecystectomies were performed at significantly higher rates in men (odds ratio: 1.95, P < .001), Asian Americans (odds ratio: 2.21, P = .037), and patients with alcohol abuse (odds ratio: 2.23, P < .001). Teaching hospitals (odds ratio: 2.41, P < .001) and those in rural areas (odds ratio: 2.26, P < .001) were more likely to perform subtotal cholecystectomies. CONCLUSION: Growing trends in the use of subtotal cholecystectomy suggest evolving surgical practices for acute cholecystitis. Our data suggests that several patient- and hospital-level characteristics might play a deciding role in procedure preference.

Trends of Hospital Palliative Care Utilization and Its Associated Factors Among Patients With Systemic Lupus Erythematosus in the United States From 2005 to 2014.

OBJECTIVE: To investigate trends and associated factors of utilization of hospital palliative care among patients with systemic lupus erythematosus (SLE) and analyze its impact on length of hospital stay, hospital charges, and in-hospital mortality. METHODS: Using the 2005-2014 National Inpatient Sample in the United States, the compound annual growth rate was used to investigate the temporal trend of utilization of hospital palliative care. Multivariate multilevel logistic regression analyses were performed to analyze the association with patient-related factors, hospital factors, length of stay, in-hospital mortality, and hospital charges. RESULTS: The overall proportion of utilization of hospital palliative care for the patient with SLE was 0.6% over 10 years. It increased approximately 12-fold from 0.1% (2005) to 1.17% (2014). Hospital palliative care services were offered more frequently to older patients, patients with high severity illnesses, and in urban teaching hospitals or large size hospitals. Patients younger than 40 years, the lowest household income group, or Medicare beneficiaries less likely received palliative care during hospitalization. Hospital palliative care services were associated with increased length of stay (ß = 1.407, P < .0001) and in-hospital mortality (odds ratio, 48.18; 95% confidence interval, 41.59-55.82), and reduced hospital charge (ß = -0.075, P = .009). CONCLUSION: Hospital palliative care service for patients with SLE gradually increased during the past decade in US hospitals. However, this showed disparities in access and was associated with longer hospital length of stay and higher in-hospital mortality. Nevertheless, hospital palliative care services yielded a cost-saving effect.

Complications and Mortality Rates Following Surgical Management of Extradural Spine Tumors in New York State.

STUDY DESIGN: Database analysis. OBJECTIVE: To evaluate complications and mortality in patients undergoing surgical management of extradural spinal tumors in New York State. SUMMARY OF BACKGROUND DATA: Metastatic spine surgery has a high rate of complications but most studies are limited to single institutions. METHODS: The Statewide Planning and Research Cooperative System was used to identify patients with extradural spinal tumors undergoing surgery in New York State from 2006 to 2015. Bivariate and multivariate logistic regression analyses were used to estimate outcomes. RESULTS: Four thousand seven hundred sixty-seven patients were identified, the majority of patients were male and white a median age of 61. The complication rate was 17.6% and the mortality rate within 30 days of discharge was 12.2%. Multivariate analysis showed the odds of complications were higher in males compared with females (odds ratio [OR]: 1.27; 95% confidence interval [CI]: 1.05-1.52, P = 0.01), and patients on Medicaid compared with patients on private insurance (OR: 1.42; 95% CI: 1.03-1.96, P = 0.03). Analysis of hospital characteristics showed lower volume hospitals (OR 1.48; 95% CI: 1.03-2.13, P value = 0.03), and teaching hospitals (OR: 1.47; 95% CI: 1.03-2.09, P = 0.04), have higher odds of complications compared with high-volume hospitals and nonteaching hospitals. Multivariate analysis showed higher odds of mortality within 30 days of discharge in patients of older age (OR: 1.02; 95% CI: 1.01-1.03, P value = 0.001), low-volume hospitals compared with high-volume hospitals (OR: 1.36; 95% CI: 1.09-1.79, P value = 0.02), hospitals with low bed size compared with high bed size (OR: 1.43; 95% CI: 1.12-1.83, P value = 0.01), and urban hospitals compared with rural hospitals (OR: 3.04; 95% CI: 2.03-4.56, P value = 0.001). CONCLUSION: Low-volume hospitals are associated with complications and mortality in patients with metastatic spine disease. LEVEL OF EVIDENCE: 3.

Atenção humanizada às mulheres em situação de abortamento e violência sexual: movimentos e ações de um coletivo de trabalho em um hospital de ensino / Humanized care for women in situations of abortion and sexual violence: movements and actions of a work collective in a teaching hospital

O aborto legal e a violência sexual são temas importantes para a saúde das mulheres no país. Porém, o acesso e a qualidade dos serviços prestados a estas demandas estão aquém do ideal. Lançada em 2011, a Rede Cegonha tem entre suas ações vinculadas o ApiceON ­ Aprimoramento e Inovação no Cuidado e Ensino em Obstetrícia e Neonatologia ­, projeto que congrega cerca de cem hospitais com atividade de ensino no país e se volta a qualificação da atenção, gestão e ensino, considerando-os componentes indissociáveis. Em Belo Horizonte, o projeto conta em com o Hospital Risoleta Tolentino Neves (HRTN) como um destes serviços. OBJETIVO: Demarcar os movimentos e ações disparadas, planejadas e/ou implementadas por um coletivo de trabalho de uma maternidade participante do projeto ApiceON na humanização do cuidado às mulheres em situação de violência sexual e abortamento, considerando seu desenho de acompanhamento avaliativo. MÉTODOS: Pesquisa qualitativa, do tipo estudo de caso, recorte de um estudo maior intitulado "Avaliação para a qualificação da atenção obstétrica e neonatal em hospitais com atividades de ensino". Foi escolhido como unidade de análise o grupo estratégico local (GEL-HRTN). Participaram deste estudo 10 trabalhadores que integravam o GEL de forma ativa no período da pesquisa. A coleta de dados ocorreu entre out./2019 e jan./2020, por meio de análise documental, observação participante e entrevista. A análise dos dados ocorreu mediante a metodologia do acompanhamento avaliativo transversal proposta pelo Projeto. RESULTADOS: O GEL realizou movimentos e ações que proporcionaram a construção do serviço de atendimento à vítima de violência sexual, assim como possibilitou o reconhecimento do trabalho coletivo como importante ferramenta para a mudança. Porém, observase que ações de gestão e formação ainda apontam como incipientes. CONCLUSÕES: Reconhece-se que este coletivo avançou nos aspectos relativos ao componente atenção. Contudo, apresentou dificuldades próprias de uma instância colegiada, em especial aquelas referentes à gestão e participação dos estudantes. Novos estudos devem ser conduzidos a fim de elucidar questões não esclarecidas neste trabalho.

Legal abortion and sexual violence are important issues for the health of women in the country. However, the access and quality of services provided to these demands are less than ideal. Launched in 2011, the Cegonha Network has among its related actions ApiceON ­ Improvement and Innovation in Care and Education in Obstetrics and Neonatology ­, a project that brings together about one hundred hospitals with teaching activity in the country, aimed at qualifying care, management and teaching, considering them inseparable components. The project in Belo Horizonte has the Hospital Risoleta Tolentino Neves (HRTN) as one of these services. OBJECTIVE: To demarcated the movements and actions triggered, planned and / or implemented by a working group from a maternity hospital participating in the ApiceON project in the humanization of care for women in situations of sexual violence and abortion, considering its evaluative follow-up design METHODS: Qualitative research , of the case study type, part of a larger study entitled "Evaluation for the qualification of obstetric and neonatal care in hospitals with teaching activities." As a unit of analysis, the local strategic group (GEL-HRTN) was chosen. They participated in this study 10 workers who actively integrated the GEL during the research period. The data collection took place between Oct / 2019 and Jan / 2020, through document analysis, participant observation and interview. The data analysis took place using the evaluation monitoring methodology transversal proposal proposed by the Project RESULTS: GEL made arrangements, and movements provided the construction of the service to victims of sexual violence, as well as making it possible to recognize collective work as an important tool for change. However, it is observed that management and training actions still point out as incipient. CONCLUSIONS: It is recognized that this group has advanced in the aspects related to the attention component, however, it presented difficulties specific to a collegiate body, especially those related to the management and participation of students. New studies should be conducted in order to elucidate issues not revealed in this work.

National trends in centralization and perioperative outcomes of complex operations for cancer.

BACKGROUND: Complex cancer operations performed at high-volume and teaching hospitals have been associated with better outcomes. The purpose of this study was to determine the national trends in the performance of these operations at large teaching hospitals. METHODS: Patients who underwent elective esophagectomies, gastrectomies, pancreatectomies, and hepatectomies for cancer (2003-2015) were identified using the National Inpatient Sample. We determined average annual percent change (AAPC) in the proportion of operations at large teaching hospitals, inpatient complications, length of stay (LOS), and inpatient mortality. RESULTS: Between 2003 and 2015, 38,932 esophageal, 104,941 gastric, 96,098 hepatic, and 137,440 pancreatic cancer resections were performed. The proportion at large teaching hospitals increased with an AAPC of 2.5 for esophagectomies (P < .001), 3.6 for gastrectomies (P < .001), and 1.5 for pancreatectomies (P = .039), but did not change for hepatectomies (AAPC 0.48, P = .50). During the study period, mean LOS and inpatient mortality rates at large teaching hospitals decreased across hospital types. By 2013 to 2015, the operations at large hospitals were associated with decreased mortality only for pancreatectomies (odds ratio, 0.62, 95% confidence interval, 0.43-0.91, P = .015). CONCLUSIONS: Complex cancer operations are performed increasingly at large teaching hospitals, but perioperative outcomes have improved nationally across hospital types. Further studies should identify actionable areas for improvement to ensure accessible quality cancer care.

Pain and Palliative Care Service, Massachusetts Society for the Prevention of Cruelty to Animals-Angell Animal Medical Center.

A veterinary palliative care service was developed as a specialty service in 2006 at a large, nonprofit teaching veterinary hospital. The service originally was conceived as a pain medicine service, but quickly refocused on palliative care because a need was evident. The Pain and Palliative Care Service at Angell Animal Medical Center is structured primarily as an outpatient service, but does provide consultation services for hospitalized patients. The goals of the service, appointment structure, referral relationships, client communication issues, and practitioner sustainability are described in detail in this article as an aid to development of similar services.

Substantial Increase in Anesthesia Assistance for Outpatient Colonoscopy and Associated Cost Nationwide.

BACKGROUND AND AIMS: The use of anesthesia assistance (AA) for outpatient colonoscopy has been increasing over the past decade, raising concern over its effects on procedure safety, quality, and cost. We performed a nationwide claims-based study to determine regional, patient-related, and facility-related patterns of anesthesia use as well as cost implications of AA for payers. METHODS: We analyzed the Premier Perspective database to identify patients undergoing outpatient colonoscopy at over 600 acute-care hospitals throughout the United States from 2006 through 2015, with or without AA. We used multivariable analysis to identify factors associated with AA and cost. RESULTS: We identified 4,623,218 patients who underwent outpatient colonoscopy. Of these, 1,671,755 (36.2%) had AA; the proportion increased from 16.7% in 2006 to 58.1% in 2015 (P < .001). Factors associated with AA included younger age (odds ratios [ORs], compared to patients 18-39 years old: 0.94, 0.82, 0.77, 0.72, and 0.77 for age groups 40-49 years, 50-59 years, 60-69 years, 70-79 years, and ≥80 years, respectively); and female sex (OR, 0.96 for male patients compared to female patients; 95% CI, 0.95-0.96). Black patients were less likely to receive AA than white patients (OR, 0.81; 95% CI, 0.81-0.82), although this difference decreased with time. The median cost of outpatient colonoscopy with AA was higher among all payers, ranging from $182.43 (95% CI, $180.80-$184.06) higher for patients with commercial insurance to $232.62 (95% CI, $222.58-$242.67) higher for uninsured patients. CONCLUSIONS: In an analysis of a database of patients undergoing outpatient colonoscopy throughout the United States, we found that the use of AA during outpatient colonoscopy increased significantly from 2006 through 2015, associated with increased cost for all payers. The increase in anesthesia use mandates evaluation of its safety and effectiveness in colorectal cancer screening programs.

Exploring the current and future role of the pharmacists in osteoporosis screening and management in Malaysia.

Background Several studies have found that pharmacists can assist in screening and prevention of osteoporosis by referring patients for bone mineral density scans and counselling on lifestyle changes. In Malaysia, screening osteoporosis in all elderly women is not mandatory due to its cost. One approach to address this gap is to develop a pharmacist-led osteoporosis screening and prevention program. However, there is a paucity of data on the perspectives of Malaysian pharmacists in this area. Objective To explore the perspective of stakeholders (policy makers, doctors, pharmacists, nurses and patients) towards the role of pharmacists in osteoporosis screening and management. Setting A primary care clinic located within a teaching hospital in Kuala Lumpur, Malaysia. Method Patients (n = 20), nurses (n = 10), pharmacists (n = 11), doctors (n = 10) and policy makers (n = 5) were individually interviewed using a semi-structured topic guide. Purposive sampling was used. Interviews were transcribed verbatim and analysed using thematic analysis. Main outcome measure Perspective of stakeholders on the current and future role of pharmacists. Results All participants perceived pharmacists to be suppliers of medication, although there was some recognition of roles in providing medication advice. Nonetheless, these stakeholders were eager for pharmacists to expand their non-dispensing roles towards counselling, creating awareness and screening of osteoporosis. Interviewed pharmacists referred to their current role as 'robotic dispensers' and unanimously agreed to spread out to osteoporosis management role. Conclusion Under stakeholders there is a willingness to expand the role of pharmacists in Malaysia to non-dispensing roles, particularly in osteoporosis screening and management.

Pancreatoduodenectomy in a public versus private teaching hospital is comparable with some minor variations.

BACKGROUND: The impact of the public and private hospital systems on major abdominal operations that are demanding on clinical resources, such as pancreatic surgery, has not been explored in an Australian setting. This study examines the perioperative outcome of patients undergoing pancreatoduodenectomy (PD) at a major public and private hospital. METHODS: Patients undergoing PD between January 2004 and October 2015 were classified based on their health insurance status and location of where the surgery was performed. Clinical variables relating to perioperative outcome were retrieved and compared using univariate and multivariate analyses. RESULTS: Four hundred and twenty patients underwent PD of whom 232 patients (55%) were operated on in the private hospital. Overall, there was no difference in morbidity and mortality in the public versus the private hospital. However, there were variations in public versus private hospital, this included longer duration of surgery (443 min versus 372 min; P < 0.001), increased estimated blood loss (683 mL versus 506 mL; P < 0.001) and more patients requiring perioperative blood transfusion (25% versus 13%; P = 0.001). Of the 10 complications compared, post-operative bleeding was higher in the private hospital (11% versus 5%; P = 0.051) and intra-abdominal collections were more common in the public hospital (11% versus 5%; P = 0.028). Independent predictive factors for major complications were American Society of Anesthesiologists score (odds ratio (OR) = 1.91; P = 0.050), patients requiring additional visceral resection (OR = 3.36; P = 0.014) and post-operative transfusion (OR = 3.37; P < 0.001). The hospital type (public/private) was not associated with perioperative outcome. CONCLUSION: Comparable perioperative outcomes were observed between patients undergoing PD in a high-volume specialized unit in both the public and private hospital systems.

Large Variability in the Diversity of Physiologically Complex Surgical Procedures Exists Nationwide Among All Hospitals Including Among Large Teaching Hospitals.

BACKGROUND: Multiple previous studies have shown that having a large diversity of procedures has a substantial impact on quality management of hospital surgical suites. At hospitals with substantial diversity, unless sophisticated statistical methods suitable for rare events are used, anesthesiologists working in surgical suites will have inaccurate predictions of surgical blood usage, case durations, cost accounting and price transparency, times remaining in late running cases, and use of intraoperative equipment. What is unknown is whether large diversity is a feature of only a few very unique set of hospitals nationwide (eg, the largest hospitals in each state or province). METHODS: The 2013 United States Nationwide Readmissions Database was used to study heterogeneity among 1981 hospitals in their diversities of physiologically complex surgical procedures (ie, the procedure codes). The diversity of surgical procedures performed at each hospital was quantified using a summary measure, the number of different physiologically complex surgical procedures commonly performed at the hospital (ie, 1/Herfindahl). RESULTS: A total of 53.9% of all hospitals commonly performed <10 physiologically complex procedures (lower 99% confidence limit [CL], 51.3%). A total of 14.2% (lower 99% CL, 12.4%) of hospitals had >3-fold larger diversity (ie, >30 commonly performed physiologically complex procedures). Larger hospitals had greater diversity than the small- and medium-sized hospitals (P < .0001). Teaching hospitals had greater diversity than did the rural and urban nonteaching hospitals (P < .0001). A total of 80.0% of the 170 large teaching hospitals commonly performed >30 procedures (lower 99% CL, 71.9% of hospitals). However, there was considerable variability among the large teaching hospitals in their diversity (interquartile range of the numbers of commonly performed physiologically complex procedures = 19.3; lower 99% CL, 12.8 procedures). CONCLUSIONS: The diversity of procedures represents a substantive differentiator among hospitals. Thus, the usefulness of statistical methods for operating room management should be expected to be heterogeneous among hospitals. Our results also show that "large teaching hospital" alone is an insufficient description for accurate prediction of the extent to which a hospital sustains the operational and financial consequences of performing a wide diversity of surgical procedures. Future research can evaluate the extent to which hospitals with very large diversity are indispensable in their catchment area.

The pattern, peculiarities, and management challenges of spina bifida in a teaching hospital in Southwest Nigeria.

PURPOSE: Spina bifida is a common congenital anomaly of the nervous system. It is frequently associated with significant morbidity and sometimes mortality in affected children. In this paper, we review the clinico-epidemiological pattern, peculiarities, and therapeutic challenges of this condition in our practice setting. METHODS: This is a retrospective study of all cases of spina bifida managed from July 2000 to March 2016 at a tertiary health facility located in the southwest region of Nigeria. Relevant information was retrieved from the medical records. The data was collected using a pro forma and analyzed with SPSS version 22. RESULTS: Data from 148 patients was reviewed and analyzed. There were 78 males and 70 females. Only 5.8% of these children were delivered at the health institution. A fifth (20%) of the patients were first born of their mothers. The mean maternal age was 29 years. Few (10.1%) mothers use folate medication prior to conception and only 58% of the mothers use folate during antenatal care. Mean duration of pregnancy was 38 weeks. The most common anatomical site was lumbosacral region (74.3%) while the most common pathology was myelomeningocele 80.4%. Mean age at surgery was 88.68 h. Mean duration of surgery was 92.8 min. Mean follow-up duration was 46.8 weeks. As many as 59% of the patients had some neurologic improvement noticed during follow-up clinic visits. CONCLUSION: Spina bifida occurs frequently in our environment. Low socio-economic status and poor antenatal clinic visits contributes significantly to its occurrence.

Two-year audit of outcomes of pituitary surgery at an Australian teaching hospital.

BACKGROUND: There is evidence that cure rates and complications are influenced by the caseload in neurosurgical centres performing transsphenoidal pituitary surgery. Although Australian centres may perform relatively small numbers of these procedures, there have been few published audits of their performance. AIMS: To conduct an audit of surgery for pituitary tumours between 2012 and 2014 in the only public hospital neurosurgical unit in the state of Western Australia. METHODS: A retrospective chart review was conducted, with standardised extraction of data relating to indications for surgery, tumour type, procedure and postoperative endocrinological and other outcomes. RESULTS: Of 53 patients identified, most (91%) underwent transsphenoidal surgery. Most tumours were non-functioning (71.7%), and most of these extended outside the sella turcica (86.8 vs 73.3% of functioning tumours). There was complete removal in 43.4% of patients and evidence of biochemical cure in 33.3% of functioning tumours, but readmission for further surgery was infrequent (5.7%). Persistent cerebrospinal fluid leakage, photophobia and deep venous thrombosis occurred in <4% of patients. There were no deaths. There was a relatively high rate of permanent diabetes insipidus (DI) (13.2 vs <5% in published series), while the frequency of new postoperative anterior pituitary dysfunction (9.4%) was within the range reported in the literature (3-14%). CONCLUSION: The outcomes of pituitary surgery in this audit were largely comparable to those reported from other neurosurgical units in Australia and other countries. The increased risk of permanent postoperative DI may reflect the high proportion of non-functioning tumours with extension outside the sella turcica.

Incidence and diagnosis of Acute kidney injury in hospitalized adult patients: a retrospective observational study in a tertiary teaching Hospital in Southeast China.

BACKGROUND: Acute kidney injury (AKI) places a heavy burden on the healthcare system in China and is usually misdiagnosed. However, there are limited studies that have described the epidemiology and diagnosis of AKI in China. The aim of this study was to describe the incidence and diagnosis of AKI in hospitalized adult patients in a tertiary teaching hospital in southeast China. METHODS: All adult patients hospitalized from October 1, 2013 to September 30, 2014 in the First Affiliated Hospital of Nanjing Medical University were screened using the Lab Administration Network. AKI definition and staging were based on the KDIGO AKI criteria. Demographic characteristics, laboratory examination, clinical data, and clinical outcomes of AKI patients were recorded and analyzed. RESULTS: The incidence of AKI was 1.6% (1401/87196). The 30-day mortality was 35.3%. AKI stage 1, 2, 3 and RRT accounted for 38.0% (532/1401), 22.0% (309/1401), 40.0% (560/1401), and 16.3% (228/1401) of patients, respectively. The Renal, other Internal Medicine, Surgery, and ICU Departments accounted for 7.4%, 37.1%, 30.1%, and 25.4% of AKI patients, respectively. The timely diagnosis rate, delayed diagnosis rate, and missed diagnosis rate were 44% (616/1401), 3.3% (46/1401), and 52.7% (739/1401), respectively. Patients hospitalized in the Renal Department had the highest AKI diagnosis rate (89.3%, 88/103), while missed diagnosis rate of the surgical patients was as high as 75.1% (317/422). Multivariable logistic regression analysis indicated that presence of tumors, higher serum albumin, and AKI stage 1 were associated with failure to timely diagnose AKI, whereas presence of chronic kidney disease, oliguria, higher blood urea nitrogen, and greater number of organ failures correlated with earlier diagnosis. CONCLUSIONS: AKI was characterized by a high incidence, high short-term mortality, and high missed diagnosis rate in hospitalized adult patients in our hospital. Interventions for improving diagnosis of AKI are urgently needed.
