The surgical safety checklist survey: a national perspective on patient safety.

BACKGROUND: In 2008, the World Health Organisation (WHO) recommended practices to ensure the safety of patients worldwide. This led to the development of the Surgical Safety Checklist (SSC). Ireland has endorsed the SSC ( www.hiqa.ie/press-release/2008-06-17-health-information-and-quality-authority-launches-world-health-organization , 10). OBJECTIVES: We aimed to determine (i) whether SSC is being implemented, (ii) whether it promotes a safer surgical environment and (iii) identify problems associated with its introduction and on-going implementation. METHODS: All hospitals in Ireland with operating departments (n = 61) were invited to participate in an online survey. RESULTS: The response rate was 67 %. The WHO SSC or modified version is in place in 78 % (mean time: 20 months) of operating departments that responded. Partaking in Time Out as a team was reported as occurring in 57 % of cases. Greater than 60 % of respondents reported that the SSC was difficult to introduce and implement and that its introduction was time consuming. Further training in using the SSC was reported as desirable by 84 % of respondents. The introduction of the SSC was reported to be associated with an improvement in team communication (72 %), a positive change in team behaviour (63 %), an increase in the consistency of patient care (82 %) and a positive culture of safety in theatre (81 %). CONCLUSION: The SSC has not been implemented throughout all operating departments in Ireland. Where it has been introduced there has been a perceived positive change in safety culture. However, overall greater education, endorsement, teamwork, and communication will be required to optimise the potential benefits associated with this safety instrument. In order to properly determine the benefit of the SSC following its implementation, a formal audit of morbidity and mortality is required.

Quality of rectal cancer surgery and its relationship to surgeon and hospital caseload: a population-based study.

AIM: A population-based audit of all rectal cancers diagnosed in Ireland in 2007 has shown an inconsistent relationship between surgeon and hospital caseload and a range of quality measures. Better outcome for rectal cancer has been associated with increasing surgeon and hospital caseload, but there is less evidence of how this may relate to quality of care. Our aim was to examine how measures of quality in rectal cancer surgery related to surgeon and hospital workload and to outcome. METHOD: All colorectal surgeons in Ireland participated in an audit of rectal cancer based on an evidence-based instrument. Data were extracted from medical records by trained coders. Generalized linear mixed models were used to determine the relationship between surgeon or hospital caseload and measures of quality of care. RESULTS: Five hundred and eighty-one (95%) of the 614 rectal cancers diagnosed in Ireland in 2007 were audited; 49 hospitals and 86 surgeons participated. Ten (28%) hospitals treated fewer than five cases and seven fewer than three. A positive relationship between caseload and quality was seen for a few measures, more frequently for hospital than surgeon caseload. The relationship between caseload and quality of care was inconsistent, suggesting these measures do not represent a single dimension of quality. One-year survival was negatively associated with hospital caseload. There was no statistically significant relationship between survival and measures of quality of care. DISCUSSION: Quality of care was inconsistently influenced by surgeon and hospital caseload. Caseload may affect only one aspect of surgical management, such as the quality of preoperative workup, and is not necessarily related to the quality of other hospital care. Simple measures of outcome, such as survival, cannot represent the complexity of this relationship.

The management of rectal cancer in Ireland in 2007--room for improvement?

INTRODUCTION: Effective management of rectal cancer relies on accurate pre-operative assessment, surgical technical excellence and integrated neoadjuvant and adjuvant chemo and/or radiotherapy. The aim of this study was to examine the management of rectal cancer in Ireland. METHODS: This was a retrospective chart review. All cases of rectal cancer (15 cm or less from the anal verge) diagnosed in Ireland in the year 2007 were included in the audit. RESULTS: In total data for 585 patients were included, under the care of 87 consultant surgeons operating in 48 hospitals. Only data recorded in medical charts were included. Pre-operative investigations were less utilised than recommended by current guidelines and consequently many cancers were inadequately staged. In total 52.5% of cases were discussed at a multi-disciplinary meeting. Overall, 88% of the patients had surgery, and the 30-day mortality rate was 1.7%. The quality of post-operative pathology reporting was variable, with adequacy of total mesorectal excision status unclear or unknown in 74% of cases. Cases were managed in a large number of centres, and in lower volume centres (<5 cases per annum) patients appeared to be less adequately investigated. CONCLUSION: This study gives a snapshot of recent practice in the management of rectal cancer in Ireland but is of necessity limited as the audit was retrospective and long term outcomes have not been assessed. In 2007 rectal cancer was managed in a large number of centres and best practice was frequently not adhered to. The impending centralisation of cancer services is likely to impact on the management of rectal cancer in Ireland.

The RAPID protocol enhances patient recovery after both laparoscopic and open colorectal resections.

BACKGROUND: Enhanced recovery after surgery (ERAS) programs can accelerate recovery and shorten the hospital stay after colorectal resections. The RAPID (remove, ambulate, postoperative analgesia, introduce diet) protocol is a simplified ERAS program that consists of a simplified, user-friendly single-page pro forma schedule. This study aimed to evaluate the impact of the RAPID protocol on patients undergoing both laparoscopic and open colorectal resections in two specialized colorectal units. METHODS: A prospective, two-center study assessed 117 age-matched patients undergoing open or laparoscopic colorectal resection to compare the postoperative course for patients using the RAPID protocol with those treated in a traditional manner. RESULTS: Of the 117 patients studied, 70 underwent laparoscopic resection (55 with the RAPID protocol) and 47 underwent open resection (25 with the RAPID protocol). Patients undergoing laparoscopic resections with the RAPID protocol had a significantly shorter hospital stay (p = 0.01) and tolerance of a full diet (p = 0.002). Similarly, patients undergoing open resections with the RAPID protocol also have a significantly shorter hospital stay (p = 0.04). CONCLUSION: The RAPID protocol is a user-friendly, easy, and effective tool that facilitates earlier tolerance of diet and discharge from the hospital for patients undergoing laparoscopic or open colorectal resections.

Laparoscopic colonic resection in inflammatory bowel disease: minimal surgery, minimal access and minimal hospital stay.

OBJECTIVE: Laparoscopic surgery for inflammatory bowel disease (IBD) is technically demanding but can offer improved short-term outcomes. The introduction of minimally invasive surgery (MIS) as the default operative approach for IBD, however, may have inherent learning curve-associated disadvantages. We hypothesise that the establishment of MIS as the standard operative approach does not increase patient morbidity as assessed in the initial period of its introduction into a specialised unit, and that it confers earlier postoperative gastrointestinal recovery and reduced hospitalisation compared with conventional open resection. METHOD: A case-control study was undertaken on laparoscopic resection (LR) vs open colon resection (OR) for IBD. The LR group was collated prospectively and compared with a pathologically matched historical control set. Outcomes measured included: postoperative length of stay, time to normal bowel function and postoperative morbidity. Statistical analysis was performed using spss. RESULTS: Twenty-eight patients were investigated (14 LR, 14 OR). The two groups were matched for type of operation, type of disease and age. There were no conversions in the LR group. Morbidity and readmissions did not differ significantly between the groups. Those undergoing laparoscopic resection had a quicker return to diet (median 2 vs 4 days; P = 0.000002), time to first bowel motion (2 vs 4 days; P = 0.019) and shorter postoperative length of stay (5.5 vs 12.5; P = 0.0067). CONCLUSION: These findings support the routine use of MIS for the elective surgical management of IBD in our department. Patients undergoing laparoscopic colectomies for IBD can expect faster return of gastrointestinal function and shorter hospitalisation.

Gossypiboma: a case report and review of the literature.

INTRODUCTION: Post-operative complications in surgery may frequently be unavoidable. However, some complications result from human error, both in the intra-operative and post-operative period. One such complication, which is frequently underreported, is the retained swab, or gossypiboma. CASE REPORT: We report a case from our hospital of a patient who presented with unexplained pyrexia, 4 years post-gynaecological surgery in another institution. A 67-year-old woman from overseas presented to our emergency department with a 2-day-history of pyrexia, collapse and confusion. Following a CT guided biopsy, which was inconclusive, she was scheduled for retroperitoneal biopsy. In theatre, a retained swab was discovered. CONCLUSION: Prevention of gossypiboma is far better than cure. Strict adherence to swab counts, and the avoidance of change of staff during procedures is important in decreasing the incidence. Perhaps, with the increasing use of minimally invasive procedures, the incidence of gossypiboma will fall dramatically.

Laparoscopic colectomy is cheaper than conventional open resection.

OBJECTIVE: International randomized trials have endorsed the routine use of laparoscopic techniques in colorectal surgery. The authors hypothesize that the overall care pathway in minimal access resection was cheaper than conventional open resection. METHOD: This was a case-matched study of consecutive patients undergoing laparoscopic resection between July 2005 and February 2006. Intraoperative (costs, duration, incision length) and postoperative [morbidity, length of stay (LOS), readmission] parameters were examined. Institutional retrospective open controls and national validated figures were used for costings. RESULTS: Thirty-five laparoscopic and 53 open resections were evaluated. Median LOS was 5 days in the laparoscopic group vs 12 in the open group (P = 0.001). There were two conversions (5.7%) and two readmissions. Mean operative cost of laparoscopic resection was 1557.08 euros, therefore 2.4 bed days need to be saved to recoup the increased cost compared with open resection. The actual median save is 7 days (P = 0.031). A mean of 4591.38 euros and 7 bed days per case is saved by performing the resection laparoscopically. Subgroup analysis of laparoscopic resections clearly demonstrates similar trends. CONCLUSION: The institutional saving is over 150,000 euros and 245 bed days during the study period. Despite higher operative spending, laparoscopic colorectal resections are significantly cheaper than conventional open resections.

Non-seminomatous testicular metastasis mimicking acute appendicitis.

This is the first report in the literature of a non-seminomatous metastasis from an occult testicular primary that presented as an acute appendicitis. The report highlights the necessity of testicular re-imaging in cases of occult malignancy and reviews the association of chromosome 12 with embryonal germ cell tumours.

Unusual presentation of an appendiceal malignancy.

Primary malignant epithelial tumors of the appendix are uncommon. The most common presentation of appendiceal malignancy is right lower abdominal pain suggestive of acute appendicitis. Presentation caused by loco-regional spread with involvement of neighboring organs is rare. We present the case of a 48-year-old woman with an appendiceal malignancy who presented with symptoms and signs suggestive of complicated diverticular disease with an enterovaginal fistula. From a review of the literature, this is the first report of an appendiceal malignancy presenting in this manner.

Patients' recall of clinical information following laparoscopy for acute abdominal pain.

BACKGROUND: Failures in doctor-patient communication and patients' understanding continue to confound improvements in the delivery of quality healthcare. In the context of acute abdominal pain managed by means of laparoscopy, it was hypothesized that patients are either not adequately informed, or do not reliably retain simple relevant information transmitted at the time of the procedure. This study was designed to evaluate the reliability of information transfer between doctor and patient in this setting, including the diagnosis and whether or not the appendix was removed. METHODS: A retrospective study of 350 consecutive patients who had undergone laparoscopy for acute abdominal pain over 3.5 years was designed. Each patient completed a telephone questionnaire that was used to evaluate the accuracy of patients' information. RESULTS: In total, 26.9 per cent of patients did not know or were incorrect regarding the surgical procedure performed. Similarly, 20.0 per cent of all patients did not know or were incorrect regarding the status of their appendix after surgery and 30.0 per cent of patients were incorrect regarding the diagnosis. Despite all of these statistics, 91.4 per cent of patients were happy with the information they had received regarding the procedure. CONCLUSION: Some 26.9 per cent of patients who underwent laparoscopy for acute abdominal pain were incorrect or did not know about the procedure that had been performed. This could lead to a further unnecessary operation should they re-present with similar symptoms.

The influence of bladder filling on anorectal function.

OBJECTIVE: The aim of this study was to develop a technique to simultaneously evaluate bladder and anorectal function. In particular, this study was designed to determine if anal sphincter resting pressure, anal sphincter squeeze pressure and rectal sensation change with bladder filling. PATIENT AND METHODS: A pilot study of ten female patients who presented to the pelvic physiology unit for assessment of urinary symptoms was performed. All patients completed a symptom questionnaire and quality of life assessment form. Following informed consent a baseline urodynamic test was performed with the bladder empty and subsequently followed by an anorectal manometric test. Changes in anal sphincter resting pressure, squeeze pressure and rectal pressure were recorded over a ten-minute period. With the patient lying in the left lateral position, the bladder was then filled with isotonic saline at room temperature at a constant rate of 30 ml/min. A continuous assessment of changes in anal sphincter resting pressure during bladder filling was made. Anal sphincter squeeze pressure and rectal sensation were measured at fixed intervals during bladder filling (50, 100, 150 ml etc.) and at fixed intervals relative to bladder capacity (25, 50, 75 and 100% capacity) by stopping bladder filling at the appropriate level. RESULTS: There was no significant change in anal sphincter resting pressure (Mean difference(s.d.) between bladder full and empty = 2.7(5.6) P = 0.92*), squeeze pressure (Mean(s.d.) difference = 9.5(26.3) P = 0.86*) and rectal sensation (Mean difference(s.d.) first sensation 10(15.2) P = 0.958; Mean difference(s.d.) urgency = 10(17.8) P = 0.07*) on bladder filling. CONCLUSION: Under normal physiological circumstances, bladder filling does not influence anorectal function. * STATISTICAL ANALYSIS: Wilcoxon signed rank sum test. P < 0.05 considered significant.

Minimally invasive techniques in common surgical procedures: implications for training.

BACKGROUND: Laparoscopic techniques are increasingly used in common surgical procedures. Many of these procedures are used to teach basic surgical trainees (BST) and therefore introduction of these techniques may have implications for training. AIMS: To establish whether the introduction of laparoscopic techniques reduced the opportunity of BSTs to perform surgical procedures. METHODS: Patients undergoing hernia repair or appendicectomy in 1991 (when laparoscopy was first introduced) and 1997 (when laparoscopy was readily available) were identified using the Hospital In-Patient Enquiry (HIPE) database. The principal operator and whether the procedure was open or laparoscopic were identified by chart review. RESULTS: The data showed a 50% reduction in the number of appendicectomies performed by BSTs following the introduction of laparoscopic techniques. The number of hernia repairs performed by BSTs has been preserved but the proportion by BSTs fell from 10 to 6%. The proportion of BST-performed procedures carried out laparoscopically has been reduced compared with the registrar-performed group. CONCLUSIONS: The use of minimally invasive techniques has had a negative effect on surgical training. Appropriate measures must be taken to minimise this and such measures should include a structured approach to laparoscopic training and greater access to laparoscopic training facilities.

Surgical informatics on the Internet: any improvement?

PURPOSE: The Internet is a popular, but ungoverned, source of medical information. This study tracked the change in performance of commonly available search engines and the quality of medical data therein over a four-year period. METHODS: We compared the accuracy of information on a commonly performed surgical procedure (vasectomy) using six standard search engines in a four-year period and with two recently developed search engines. The top 25 ranked sites cited by each search engine were scored for description of the procedure, post-operative instructions, complications and unproven associations. RESULTS: There was no improvement in quality of individual sites over the study period. Additionally, the hit rate of search engines remained poor with 27 sites cited (40%) in 2002 either irrelevant or unavailable. DISCUSSION: Few useful sites with accurate information on surgical procedures are available on the Internet and simple search strategies fail to identify site quality or relevancy. CONCLUSION: At present, the Internet cannot be recommended as a reliable resource for many aspects of health information for patients. The onus is on health-care providers to provide high quality sites and direct patients to these sources of reliable information

Granulomatous appendicitis.

Granulomatous inflammation of the appendix is uncommon. It can be caused by a variety of conditions, including systemic disorders such as Crohn's disease and sarcoidosis, and infections such as mycobacterium tuberculosis, yersinia pseudotuberculosis, parasites and fungi. Granulomatous appendicitis as an isolated pathological entity unassociated with systemic disease is rare. Isolated granulomatous inflammation of the appendix of unknown aetiology, otherwise known as idiopathic granulomatous appendicitis is extremely rare. Patients with this condition present with the typical signs and symptoms of acute appendicitis. We present a series of patients with isolated granulomatous inflammation of the appendix, and discuss the difficulties encountered in the management of this condition.

Acute pancreatitis.

Acute pancreatitis is an important and extremely common cause of acute hospital admission which may be associated with major morbidity and mortality. Modern treatment is largely supportive with a limited role for surgery.

An evaluation of the prognostic significance of vascular endothelial growth factor in node positive primary breast carcinoma.

Angiogenesis is intimately related to the growth and progression of tumours and must be induced to facilitate growth beyond a minimum size. It has been implicated in the development of metastases and survival in breast carcinoma. VEGF is a cytokine that plays an important role in angiogenesis. Its expression is increased in solid tumours during induction of angiogenesis and it has been implicated as a prognostic marker in patients with node negative breast carcinoma. We studied VEGF expression, in a series of patients with node positive breast carcinoma and examined histopathological parameters of the tumour and the prognostic value of VEGF expression. Specimens from 108 cases of node positive breast cancer were stained for VEGF using an antibody suitable for use on formalin fixed tissue. VEGF staining was cytoplasmic and was scored by intensity and the percent positive cells. Patients with positive VEGF staining (n=48) were compared with patients with negative VEGF staining (n=60). Demographic criteria were similar in both groups. Only one (12%) patient with lobular carcinoma and one (14%) patient with medullary carcinoma expressed VEGF compared with 46 (49%) patients with ductal carcinoma (NOS). DCIS was present in 60 tumours. There was a strong correlation between staining in DCIS and the adjacent invasive tumours. There was no significant association between VEGF staining and T stage, tumour size or the number of positive lymph nodes. VEGF expression had no prognostic significance either for disease-free or overall survival in patients with node positive disease. This study failed to support a role for VEGF as a prognostic marker in patients with node positive breast carcinoma.

An immunohistochemical study of p21 and p53 expression in primary node-positive breast carcinoma.

AIMS: p21, an inhibitor of cyclin-dependent kinase, is involved in the p53 pathway of growth control. Its expression has been linked to cellular differentiation. It has been implicated in p53-mediated growth arrest following DNA damage and in terminally differentiated cells. This study analysed p21 and p53 expression, in a series of node-positive patients with breast carcinoma and examined histopathological parameters of the tumour and the prognostic implications of p21 and p53 expression. METHODS: One hundred and five consecutive patients with node-positive disease and at least 3 years follow-up were identified. Sections were stained for p53 and p21 using monoclonal antibodies. Results were expressed as percentage positive cells, and over 20% considered positive for p53 and over 10% considered for p21. RESULTS: p21 was overexpressed (>10% of cells positive) in 65% of patients and p53 was overexpressed (>20% of cells positive in 68%. The mean (SEM) level of p21 staining was 5.7(0.8)% and was 54.9(4.0)% for p53. There was no correlation between p21 and p53 expression (r=0.071 P=0.5). There were no significant differences in demographic criteria between patients that were p21 positive or negative and p53 positive or negative. There were no significant differences in tumour type, grade or stage between the groups. p21 expression did not have prognostic significance; however, p53 positivity was associated with a worse prognosis, which remained when controlled for stage. CONCLUSIONS: This study demonstrated p21 overexpression in 65% of patients with node-positive breast carcinoma. Levels did not correlate with p53 status and unlike p53 failed to have prognostic significance.

Should an appendix that looks 'normal' be removed at diagnostic laparoscopy for acute right iliac fossa pain?

OBJECTIVE: To find out whether the removal of the appendix from patients in whom laparoscopy for acute right iliac fossa pain shows no abnormality is justified to avoid the risk of missing acute appendicitis. PATIENTS: The records of patients who, between 1990 and 1997 had emergency laparoscopy for acute right iliac fossa pain were reviewed. Only those in whom laparoscopy had shown no abnormality and had not had the appendix removed were included in the study. METHODS: Outcome was assessed by telephone questionnaire to the patient, the general practitioner, or both. RESULTS: Emergency laparoscopy had been done for 254 patients. No abnormality was detected in 41. Full follow up was available on 34 patients (83%). 21 patients have remained entirely free of symptoms. Of the 13 patients who had recurrent symptoms, 2 subsequently had a histologically normal appendix removed, yet still had symptoms; 2 had a second laparoscopy that showed no abnormality; 5 had ultrasound; and 4 had colonoscopy or a barium enema examination. CONCLUSION: Removal of an appendix that looks 'normal' at emergency laparoscopy for right iliac fossa pain is unjustified.
