Data Collection Background and Data Quality The ACS NSQIP collects data on over 150 variables, including preoperative risk factors, intraoperative variables, and 30-day postoperative mortality and morbidity outcomes for patients undergoing major surgical procedures in both the inpatient and outpatient setting. A site’s trained and certified Surgical Clinical Reviewer (SCR) captures these data using a variety of methods including medical chart abstraction. Required data variables are entered via web-based data collection to the ACS NSQIP website. Portions of the data may be automatically populated by a software program that was developed to extract data from the participating hospital’s existing information systems. Requestors should contact the SCR(s) at their hospital for detailed information on how the hospital collects its ACS NSQIP data. To ensure the data collected are of the highest quality, the ACS NSQIP has developed a host of different training mechanisms for the SCRs and conducts an Inter-Rater Reliability (IRR) Audit of selected participating sites.

  • The Differences Between ICD-9 and ICD-10

    The Differences Between ICD-9 and ICD-10

    Preparing for the ICD-10 Code Set: Fact Sheet 2 October 1, 2015 Compliance Date Get the Facts to be Compliant Alert: The new ICD-10 compliance date is October 1, 2015. The Differences Between ICD-9 and ICD-10 This is the second fact sheet in a series and is focused on the differences between the ICD-9 and ICD-10 code sets. Collectively, the fact sheets will provide information, guidance, and checklists to assist you with understanding what you need to do to implement the ICD-10 code set. The ICD-10 code sets are not a simple update of the ICD-9 code set. The ICD-10 code sets have fundamental changes in structure and concepts that make them very different from ICD-9. Because of these differences, it is important to develop a preliminary understanding of the changes from ICD-9 to ICD-10. This basic understanding of the differences will then identify more detailed training that will be needed to appropriately use the ICD-10 code sets. In addition, seeing the differences between the code sets will raise awareness of the complexities of converting to the ICD-10 codes. Overall Comparisons of ICD-9 to ICD-10 Issues today with the ICD-9 diagnosis and procedure code sets are addressed in ICD-10. One concern today with ICD-9 is the lack of specificity of the information conveyed in the codes. For example, if a patient is seen for treatment of a burn on the right arm, the ICD-9 diagnosis code does not distinguish that the burn is on the right arm.

  • About Liver Resection

    About Liver Resection

    ABOUT LIVER RESECTION Surgical removal of part of the liver A guide for patients and relatives This booklet has been written to provide information about the operation called a liver resection. This is a major operation and involves removal of a part of the liver. Information about the benefits and risks will help you make an informed decision about the operation. It is important to remember that each person is different. This booklet cannot replace the professional advice and expertise of a doctor who is familiar with your condition. If you have questions that this booklet does not cover, please discuss them with your surgeon or cancer nurse specialist. page 2 What is the liver? The liver is a large organ which lies on the right side of the upper abdomen, under the rib cage. It has many functions related to body metabolism (chemical processes within the body) and is very important to health. One of its functions is to produce yellow-green fluid called bile. Bile flows down a tube called the bile duct to the intestine, where it mixes with food and helps digestion. The gall bladder is a small sac attached to the side of the bile duct. The gall bladder stores excess bile and pushes it down the bile duct in to the intestine, ready for when it is needed for digestion. The liver has right and left lobes (sections). An artery (hepatic artery) and a vein (portal vein) carry blood to the liver. Blood from the liver flows through the hepatic veins back to the heart.

ABSTRACT Objective: to analyze the National Cancer Institute Abdominopelvic Division (INCA / MS/HC I) initial experience with thoraco-laparoscopic esophagectomy with thoracic stage in prone position. Methods: we studied 19 consecutive thoraco-laparoscopic esophagectomies from may 2012 to august 2014, including ten patients with squamous cells carcinoma (five of the middle third and five of the lower third) and nine cases of gastroesophageal junction adenocarcinoma (six Siewert I and three Siewert II). All procedures were initiated by the prone thoracic stage. Results: There were minimal blood loss, optimal mediastinal visualization, oncological radicality and no conversions. Surgical morbidity was 42 %, most being minor complications (58% Clavien I or II), with few related to the technique. The most common complica- tion was cervical anastomotic leak (37%), with a low anastomotic stricture rate (two stenosis: 10.53%). We had one (5.3%) surgical related death, due to a gastric tube`s mediastinal leak, treated by open reoperation and neck diversion. The median Intensive Care Unit stay and hospital stay were two and 12 days, respectively. The mean thoracoscopic stage duration was 77 min. Thirteen patients received neoadju- vant treatment (five squamous cells carcinoma and eight gastroesophageal adenocarcinomas). The average lymph node sample had 16.4 lymph nodes per patient and 22.67 when separately analyzing patients without neoadjuvant treatment.

The management of patients with colorectal liver metastases and loop ileostomies remains controversial. This study was performed to assess the outcome of combined liver resection and loop ileostomy closure. Methods. Analysis of prospectively collected perioperative data, including morbidity and mortality, of 283 consecutive hepatectomies for colorectal liver metastases was undertaken. Consecutive liver resections were performed from 1996 to 2006 in one centre by a single surgeon (NDK). Fourteen of these patients had combined liver resection and ileostomy closure. Case-matched analysis was undertaken. Results.Six(2.2%) patients died in the hepatectomy only group and none died in the combined group. There was no difference in operative blood loss between the two groups (0.09). Perioperative morbidity was 36% in the combined group and 23% in the hepatectomy alone group (P = 0.33). Mean hospital stay was 14 days in the combined group and 11 days in the hepatectomy only group (P = 0.046). Case-matched analysis showed a significant increase in hospital stay (P = 0.03) and complications (P = 0.049) in the combined group.
