ABSTRACT

BACKGROUND: The rates of post-discharge deaths after surgical procedures are unknown and may represent areas of quality improvement. The NSQIP database captures 30-d outcomes not included within normal administrative databases, and can thus differentiate between in-hospital and post-discharge deaths. METHODS: Retrospective analysis of NSQIP from 2005 through 2007. Inclusion criteria were procedures whose median length of stay was greater than 1 d (to exclude outpatient procedures), and whose overall death rate was greater than 2% (to include only procedures where mortality was a significant issue). Procedures where less than 25 deaths occurred were excluded (for sample size concerns). RESULTS: There were 363,897 patients with 2236 different CPT codes captured in NSQIP. There were 6395 deaths; among them, 1486 (23.2%) occurred after discharge. Thirty-eight CPT codes met the analysis threshold. In two of the CPT codes, there were no post-discharge deaths (repair of ruptured abdominal aortic aneurysm [AAA], repair of ruptured AAA involving iliacs). In the other 36 CPT codes, the proportion of deaths occurring after discharge ranged from 6.3% (repair of thoracoabdominal aneurysm) to 50.0% (femoral-distal bypass with vein). The highest percentage of post-discharge mortality occurs on d 1 after discharge. Fifty percent of post-discharge mortality occurs by d 7; 95% occurs by d 21. CONCLUSION: Approximately one-fourth of postoperative deaths occur after hospital discharge. There is significant variation across surgical procedures in the likelihood of postoperative deaths occurring after discharge. These data indicate a need for closer and more frequent monitoring of post-surgical patients. These data also call into question conclusions drawn from hospital-based outcomes analyses for at least some key diseases/procedures. This analysis demonstrates the power of the risk-adjusted 30-d follow-up NSQIP data, but perhaps more importantly, the responsibility of surgeons to monitor and optimize the discharge process.

ABSTRACT

OBJECTIVE: The objective of this study was to determine whether the outcomes of infants with surgically managed necrotizing enterocolitis (NEC) differ according to whether the location of NEC is in the small bowel, large bowel, or both. STUDY DESIGN: A retrospective analysis was performed using the Healthcare Cost and Utilization Project Nationwide Inpatient Sample and Kids' Inpatient Database. A total of 5374 infants identified as having undergone surgical management of NEC were stratified by location of bowel affected as small bowel (SB) only, large bowel (LB) only, or both small and large bowel (SB&LB). The type of surgical operation performed was used as a proxy for the location of bowel affected. RESULTS: Of the 5374 infants with a diagnosis of NEC, 4371 had an operation that allowed for stratification by location. The LB group (n = 963) fared the best in all outcomes. The SB group (n = 2126) had the longest length of stay and highest total hospital charges, and mortality was comparable with that of the SB&LB group (n = 1282). CONCLUSIONS: Mortality, length of stay, and total hospital charges varied according to location of bowel affected by NEC.

ABSTRACT

BACKGROUND: Women have been shown to have worse outcomes compared with men after cardiac surgery, but fare better after traumatic injury. No study considers the impact of gender on outcomes after major gastrointestinal surgery. We hypothesize that the physiologic insults of a major abdominal operation are similar to an injury model; therefore, women will have improved outcomes. MATERIAL AND METHODS: We performed a retrospective review of the NIS database from 1998 to 2007. Patients undergoing major gastrointestinal surgery were identified by ICD-9 procedure codes: esophageal (42.4), gastric (43.5-43.9), small intestine (45.6), large intestine (45.7-45.8 and 17.3), rectal (48.4-48.6), hepatic (50.2-50.3), biliary (51.3 and 51.6), and pancreatic (52.5-52.7). Exclusion criteria included age over 60 y and under 18 y, multiple operations, and a sexual developmental disorder (25.52, 75.27, and 25.9). The primary outcome measure was in-hospital death. RESULTS: A total of 307,124 patients were identified, of whom 50.3% were women. Overall, there were 6574 (2.14%) deaths; 2.45% of men and 1.84% of women died (P < 0.001). In multivariate analysis, women were 21.1% less likely to die than men (OR = 0.789, 95% CI = 0.74-0.84). When subset analysis was performed, women had improved mortality in the following types of surgery: gastric (OR = 0.751, 95% CI = 0.60-0.94), small intestine (OR = 0.704, 95% CI = 0.63-0.79), large intestine (OR = 0.845, 95% CI = 0.77--0.93), hepatic (OR = 0.562, 95% CI = 0.41-0.77), and pancreatic (OR = 0.658, 95% CI = 0.49-0.89, see Fig. 1). CONCLUSIONS: Our study demonstrates that women may have improved outcomes after some types of major gastrointestinal surgery; however, the mechanism by which this occurs is unclear. Future studies are needed to further evaluate this interesting phenomenon.

ABSTRACT

BACKGROUND: The concept of surgery and public health has been introduced in recent years, highlighting the impact of surgeons on improving public health outcomes, a relationship that has traditionally been ascribed to general practitioners. The purpose of this study is to quantify the effect of surgeon availability on deaths from motor vehicle crashes (MVC). STUDY DESIGN: Retrospective analysis of the Area Resource File from 2006 was performed. The primary outcome variable was the three-year (2001-2003) average in MVC deaths per 1 million population for each county. The primary independent variable was the density of surgeons per 1 million population in year 2003. Multiple linear regression analysis was performed, adjusting for density of general practitioners, urbanicity of the county, and socioeconomic status of the county. RESULTS: A total of 3,225 counties were analyzed. The median number of MVC deaths per million population was 226 (IQR 158-320). The median number of surgeon per million population was 55 (IQR 0-105), while the median number of general practitioners per million population was 424 (IQR 274-620). On unadjusted analysis, each increase of one surgeon per million population was associated with 0.38 fewer MVC deaths per million population (p < 0.001). On multivariate analysis, each increase of one surgeon per million population was significantly associated with 0.16 fewer MVC deaths per million population (p < 0.001). Rural location, persistent poverty, and low educational level were all associated with significant increases in MVC deaths. CONCLUSIONS: Higher density of surgeons is associated with significant reduction in deaths from MVCs. This highlights the need for 1) consideration of surgery as primary care and 2) development of inclusive surgical systems designed to provide care commensurate with patients' degree of injury.

ABSTRACT

PURPOSE: To document the quality of training and experience of those who care for patients undergoing surgery and emergency obstetrical procedures at 10 government district hospitals in Ghana. METHOD: A study team composed of Ghanaian and U.S. surgeons visited 10 district hospitals in 10 different regions of Ghana in August 2009. On-site interviews were conducted documenting the formal and informal training and the experience of the medical officers (MOs) performing in surgical facilities in these hospitals. RESULTS: Fourteen of the 17 MOs working at these facilities were available for interviews. All 14 had completed two years of housemanship, which is similar to a rotating internship. Only one had obtained any formal surgical training beyond the housemanship, although all were responsible for performing major surgical procedures. The formal training under qualified supervision during the housemanship was limited; the mean number of the most common major surgical procedures performed during training ranged from four to eight, depending on the procedure. CONCLUSIONS: Even though formal general surgical residency training in Ghana is well developed, graduates of these programs are not working in the district hospitals surveyed. The majority of surgical services provided at the district hospital are provided by MOs, who would benefit from more comprehensive training and ongoing supervision. To help meet the challenge of a shortage of physicians working at district hospitals, the authors present alternative approaches to care described in the literature that involve nonphysician midlevel health providers.

ABSTRACT

BACKGROUND: For most of the population in Africa, district hospitals represent the first level of access for emergency and essential surgical services. The present study documents the number and availability of surgical and obstetrical care providers as well as the types of surgical and obstetrical procedures being performed at 10 first-referral district hospitals in Ghana. MATERIALS AND METHODS: After institutional review board and governmental approval, a study team composed of Ghanaian and American surgeons performed on-site surveys at 10 district hospitals in 10 different regions of Ghana in August 2009. Face-to-face interviews were conducted documenting the numbers and availability of surgical and obstetrical personnel as well as gathering data relating to the number and types of procedures being performed at the facilities. RESULTS: A total of 68 surgical and obstetrical providers were interviewed. Surgical and obstetrical care providers consisted of Medical Officers (8.5%), nurse anesthetists (6%), theatre nurses (33%), midwives (50.7%), and others (4.5%). Major surgical cases represented 37% of overall case volumes with cesarean section as the most common type of major surgical procedure performed. The most common minor surgical procedures performed were suturing of lacerations or episiotomies. CONCLUSIONS: The present study demonstrates that there is a substantial shortage of adequately trained surgeons who can perform surgical and obstetrical procedures at first-referral facilities. Addressing human resource needs and further defining practice constraints at the district hospital level are important facets of future planning and policy implementation.

ABSTRACT

BACKGROUND: The World Health Organization (WHO) Tool for Situational Analysis to Assess Emergency and Essential Surgical Care (hereafter called the WHO Tool) has been used in more than 25 countries and is the largest effort to assess surgical care in the world. However, it has not yet been independently validated. Test-retest reliability is one way to validate the degree to which tests instruments are free from random error. The aim of the present field study was to determine the test-retest reliability of the WHO Tool. METHODS: The WHO Tool was mailed to 10 district hospitals in Ghana. Written instructions were provided along with a letter from the Ghana Health Services requesting the hospital administrator to complete the survey tool. After ensuring delivery and completion of the forms, the study team readministered the WHO Tool at the time of an on-site visit less than 1 month later. The results of the two tests were compared to calculate kappa statistics for each of the 152 questions in the WHO Tool. The kappa statistic is a statistical measure of the degree of agreement above what would be expected based on chance alone. RESULTS: Ten hospitals were surveyed twice over a short interval (i.e., less than 1 month). Weighted and unweighted kappa statistics were calculated for 152 questions. The median unweighted kappa for the entire survey was 0.43 (interquartile range 0-0.84). The infrastructure section (24 questions) had a median kappa of 0.81; the human resources section (13 questions) had a median kappa of 0.77; the surgical procedures section (67 questions) had a median kappa of 0.00; and the emergency surgical equipment section (48 questions) had a median kappa of 0.81. CONCLUSIONS: Hospital capacity survey questions related to infrastructure characteristics had high reliability. However, questions related to process of care had poor reliability and may benefit from supplemental data gathered by direct observation. Limitations to the study include the small sample size: 10 district hospitals in a single country. Consistent and high correlations calculated from the field testing within the present analysis suggest that the WHO Tool for Situational Analysis is a reliable tool where it measures structure and setting, but it should be revised for measuring process of care.

ABSTRACT

BACKGROUND: The occurrence of discharge to home shortly after transfer from another hospital, also termed "secondary overtriage," needs to be analyzed in trauma patients because it helps to assess the efficiency of triage and transfer criteria. The extent of secondary overtriage and factors associated with it remain largely undescribed. METHODS: A retrospective analysis of the Nationwide Inpatient Sample from 2000 to 2004. Inclusion criteria were trauma patients (as identified by ICD-9 diagnosis codes of 800-959 in the primary position, excluding codes representing late effects of injury, foreign body, burn, or early complications) who were admitted as transfers from another hospital. Rapid discharge after transfer (secondary overtriage) was defined as patients who were discharged alive within 1 day after transfer and did not receive any surgical procedure. RESULTS: The overall rate of secondary overtriage was 6.9% (3,291 of 51,278), with an increasing trend over the years. This rate was significantly higher among patients younger than 18 years (19.5% vs. 4.2%). Patients meeting the definition were more likely to be male (68.3% vs. 50.65%), more likely to be black or Hispanic (25.16% vs. 16.8%), more likely to come from ZIP codes with above-median household incomes (43.4% vs. 38.1%), and more likely to be treated at teaching hospitals (77.3% vs. 61.3%). The majority of these patients (98.7%) were insured, although the proportion of uninsured patients was significantly higher among secondary overtriage (1.3% vs. 0.54%). On multivariate analysis, younger age, uninsured status, and being transferred to a teaching hospital were associated with higher likelihood of rapid discharge after transfer. No association was found with gender, race, and urbanicity. CONCLUSION: Secondary overtriage is more common in pediatric patients than in adults. The underlying causes of this occurrence need to be further investigated (e.g., fear of litigation and uneven distribution of resources). There are significant direct and indirect costs associated with these occurrences that must be considered as we identify areas of potential cost savings in our nation's health care.

ABSTRACT

OBJECTIVES: To survey infrastructure characteristics, personnel, equipment and procedures of surgical, obstetric and anaesthesia care in 17 hospitals in Ghana. METHODS: The assessment was completed by WHO country offices using the World Health Organization Tool for Situational Analysis to Assess Emergency and Essential Surgical Care, which surveyed infrastructure, human resources, types of surgical interventions and equipment in each facility. RESULTS: Overall, hospitals were well equipped with general patient care and surgical supplies. The majority of hospitals had a basic laboratory (100%), running water (94%) and electricity (82%). More than 75% had the basic supplies needed for general patient care and basic intra-operative care, including sterilization. Almost all hospitals were able to perform major surgical procedures such as caesarean sections (88%), herniorrhaphy (100%) and appendectomy (94%), but formal training of providers was limited: a few hospitals had a fully qualified surgeon (29%) or obstetrician (36%) available. CONCLUSIONS: The greatest barrier to improving surgical care at district hospitals in Ghana is the shortage of adequately trained medical personnel for emergency and essential surgical procedures. Important future steps include strengthening their number and qualifications.

ABSTRACT

BACKGROUND: Rashkind balloon atrial septostomy is a common cardiac procedure aimed at improving systemic oxygenation in newborns with cyanotic congenital cardiac defects, such as transposition of the great arteries. Recent reports on the safety of this procedure were from limited series at single institutions. We analysed two complementary national databases to evaluate clinically relevant outcomes of this procedure. METHODS AND RESULTS: We performed an analysis of transposition of the great artery patients nationwide using 15 years of the Nationwide In-patient Sample and three complementary years of the Kids' Inpatient Database. Variables included gender, race, age, and co-existing diagnoses. Outcomes included mortality, length of stay, and hospital charges. Comparison between patients undergoing Rashkind procedure or not was performed using Pearson's chi-square and Kruskal-Wallis tests. We identified 8681 patients with transposition of the great arteries, of whom 1742 (20%) underwent Rashkind procedure. Patients undergoing Rashkind procedure had lower mortality (10% versus 12%, p = 0.021), despite higher median co-morbidities and longer median length of stay. Rashkind procedure was not associated with increased risk of necrotising enterocolitis (1% versus 1%, p = 0.630), but was associated with nearly twice the risk of clinically recognised stroke (1% versus 0%, p = 0.046). CONCLUSIONS: This study represents the largest national analysis of transposition of the great artery patients to date, with a subset treated with Rashkind procedure. Patients not undergoing Rashkind procedure had higher mortality. Rashkind procedure was not associated with increased risk of necrotising enterocolitis, but was associated with twice the risk of stroke.
