Stress ulcer prophylaxis in non-critically ill patients: a prospective evaluation of current practice in a general surgery department

Objective: There is little evidence regarding the benefit of stress ulcer prophylaxis (SUP) outside critical care setting. Over-prescription of SUP is not devoid of risks. This prospective study aimed to evaluate the use of proton pump inhibitors (PPIs) for SUP in a general surgery department.Methods: Data collection was performed prospectively during an 8-week period on patients hospitalized in a general surgery department (58 beds) by pharmacists. Patients with a PPI prescription for the treatment of ulcers, gastro-oesophageal reflux disease, oesophagitis or epigastric pain were excluded. Patients admitted twice during the study period were not re-included. The American Society of Health-System Pharmacists guidelines on SUP were used to assess the appropriateness of de novo PPI prescriptions.Results: Among 255 consecutive patients in the study, 138 (54%) received a prophylaxis with PPI, of which 86 (62%) were de novo PPI prescriptions. One-hundred twenty-nine patients (94%) received esomeprazole (according to the hospital drug policy). The most frequent dosage was 40 mg/day. Use of PPI for SUP was evaluated in 67 patients. Fifty-three patients (79%) had no risk factors for SUP. Twelve and 2 patients had one or two risk factors, respectively. At discharge, PPI prophylaxis was continued in 34% of patients with a de novo PPI prescription.Conclusion: This study highlights the overuse of PPIs in non-ICU patients and the inappropriate continuation of PPI prescriptions at discharge.Treatment

Stress ulcer prophylaxis in non-critically ill patients: a prospective evaluation of current practice in a general surgery department.

RATIONALE, AIMS AND OBJECTIVES: There is little evidence regarding the benefit of stress ulcer prophylaxis (SUP) outside a critical care setting. Overprescription of SUP is not devoid of risks. This prospective study aimed to evaluate the use of proton pump inhibitors (PPIs) for SUP in a general surgery department. METHOD: Data collection was performed prospectively during an 8-week period on patients hospitalized in a general surgery department (58 beds) by pharmacists. Patients with a PPI prescription for the treatment of ulcers, gastro-oesophageal reflux disease, oesophagitis or epigastric pain were excluded. Patients admitted twice during the study period were not reincluded. The American Society of Health-System Pharmacists guidelines on SUP were used to assess the appropriateness of de novo PPI prescriptions. RESULTS: Among 255 patients in the study, 138 (54%) received a prophylaxis with PPI, of which 86 (62%) were de novo PPI prescriptions. A total of 129 patients (94%) received esomeprazole (according to the hospital drug policy). The most frequent dosage was at 40 mg once daily. Use of PPI for SUP was evaluated in 67 patients. A total of 53 patients (79%) had no risk factors for SUP. Twelve and two patients had one or two risk factors, respectively. At discharge, PPI prophylaxis was continued in 33% of patients with a de novo PPI prescription. CONCLUSIONS: This study highlights the overuse of PPIs in non-intensive care unit patients and the inappropriate continuation of PPI prescriptions at discharge. Treatment recommendations for SUP are needed to restrict PPI use for justified indications.

Educational intervention regarding hypothermia: a teaching strategy for education in the Surgery Department

This is a quasi-experimental study performed using a short-term educational intervention involving nursing aides working in a Surgery Department, with the objective to identify the social and professional characteristics of the nursing aides, identify the differences in their knowledge regarding hypothermia following the educational intervention, and relate the nursing actions to the studied variables. It was found that the educational intervention was effective, considering that the difference in the mean nursing actions was 5.35 following the intervention. However, no significant difference was found regarding the nursing actions related to the studied variables. Further studies should be performed to investigate the education of nursing professionals considering their significant learning requirements in different units.

Medication errors in a swiss cardiovascular surgery department: a cross-sectional study based on a novel medication error report method

The purpose of this study was (1) to determine frequency and type of medication errors (MEs), (2) to assess the number of MEs prevented by registered nurses, (3) to assess the consequences of ME for patients, and (4) to compare the number of MEs reported by a newly developed medication error self-reporting tool to the number reported by the traditional incident reporting system. We conducted a cross-sectional study on ME in the Cardiovascular Surgery Department of Bern University Hospital in Switzerland. Eligible registered nurses (n = 119) involving in the medication process were included. Data on ME were collected using an investigator-developed medication error self reporting tool (MESRT) that asked about the occurrence and characteristics of ME. Registered nurses were instructed to complete a MESRT at the end of each shift even if there was no ME. All MESRTs were completed anonymously. During the one-month study period, a total of 987 MESRTs were returned. Of the 987 completed MESRTs, 288 (29%) indicated that there had been an ME. Registered nurses reported preventing 49 (5%) MEs. Overall, eight (2.8%) MEs had patient consequences. The high response rate suggests that this new method may be a very effective approach to detect, report, and describe ME in hospitals.

Laparoscopic and open colorectal surgery in everyday practice : retrospective study

Résumé Introduction: La plupart des études disponibles sur la chirurgie colorectale par laparoscopie concernent des patients hautement sélectionnés. Le but de cette étude est d'analyser les résultats à court et à long terme de l'ensemble des patients traités dans un service de chirurgie générale. Méthodes: Il s'agit d'une analyse rétrospective d'un registre prospectif interne au service, dans lequel tous les patients consécutifs opérés pour la première fois du colon et du rectum entre mars 1993 et décembre 1997 ont été enregistrés. Les informations concernant le suivi ont été collectées par questionnaire. Résultats: Un total de 187 patients ont été opérés par laparoscopie et 215 patients par chirurgie ouverte durant la période d'étude. Les informations concernant le suivi ont pu être collectées dans 95% des cas avec une évolution de 1-107 mois (médiane 59 mois), respectivement de 1-104 mois (médiane 53 mois). Une conversion fut nécessaire dans 28 cas (15%) mais ceux-ci restent inclus dans le groupe laparoscopie pour l'analyse par intention de traitement. Dans le groupe laparoscopie, les opérations ont duré plus longtemps (205 vs 150 min, p<0.001) mais l'hospitalisation a été plus courte (8 vs 13 jours, p<0.001). La reprise du transit a été plus rapide après laparoscopie, mais uniquement après intervention sur le colon gauche (3 vs 4 jours, p<0.01). Cependant, la sélection préopératoire (nombre plus élevé d'urgences et de patients avec un risque anesthésiologique élevé dans le groupe de la chirurgie ouverte) a été favorable à la laparoscopie. Le taux de complications (global ainsi que pour chaque complication chirurgicale) a été similaire dans les deux groupes, avec un taux global de 20% environ. Conclusions: Malgré une sélection favorable des cas, uniquement très peu d'avantages à la laparoscopie sur la chirurgie ouverte ont pu être observés. Abstract Background: Most studies available on laparoscopic colorectal surgery focus on highly selected patient groups. The aim of the present study was to review short- and long-term outcome of everyday patients treated in a general surgery department. Methods: Retrospective review was carried out of a prospective database of all consecutive patients having undergone primary laparoscopic (LAP) or open colorectal surgery between March 1993 and December 1997. Follow-up data were completed via questionnaire. Results: A total of 187 patients underwent LAP resection and 215 patients underwent open surgery. Follow up was complete in 95% with a median of 59 months (range, 1-107 months) and 53 months (range, 1-104 months), respectively. There were 28 conversions (15%) in the LAP group and these remained in the LAP group in an intention-to-treat analysis. The LAP operations lasted significantly longer for all types of resections (205 vs 150 min, P<0.001) and hospital stay was shorter (8 vs 13 days, P<0.001). Recovery of intestinal function was faster in the LAP group, but only after left-sided procedures (3 vs 4days, P<0.01). However, preoperative patient selection (more emergency operations and patients with higher American Society of Anesthesiologists (ASA) score in the open group) had a major influence on these elements and favours the LAP group. Surprisingly, the overall surgical complication rate (including long-term complications such as wound hernia) was 20% in both groups with rates of individual complications also being comparable in both groups. Conclusion: Despite a patient selection favourable to the laparoscopy group, only little advantage in postoperative outcome could be shown for the minimally invasive over the open approach in the everyday patient.

Cost-effective utilization of a private facility to perform outpatient surgery in public hospital waiting list patients.

Background: Public hospitals' long waiting lists make outpatient surgery in private facilities very attractive provided a standardized protocol is applied. The aim of this study was to assess this kind of innovative collaboration in abdominal surgery from a clinical and economical perspective. Methods: All consecutive patients operated on in an outpatient basis in a private facility by a public hospital abdominal surgeon and an assistant over a 5-year period (2004-2009) were included. Clinical assessment was carried out from patients' charts and satisfaction questionnaire, and economic assessment from the comparison between the surgeons' charges paid by the private facility and the surgeons' hospital salaries during the days devoted to surgery at the private facility. Results: Over the 5 years, 602 operative procedures were carried out during 190 operative days. All patients could be discharged the same day and only 1% of minor complications occurred. The patients' satisfaction was 98%. The balance between the surgeons' charges paid by the private facility and their hospital salary costs was positive by 25.8% for the senior surgeon and 12.6% for the assistant or, on average, 21.9% for both. Conclusion: Collaboration between an overloaded university hospital surgery department and a private surgical facility was successful, effective, safe, and cost-effective. It could be extended to other surgical specialities. Copyright (C) 2011 S. Karger AG, Basel

Cirurgia do Timo num Serviço de Cirurgia Geral

AIMS: Evaluation of thymectomy cases between 1990-2003, in a General Surgery Department. Evaluation of the therapeutic efficacy in Miastenia Gravis patients. PATIENTS AND METHODS: Retrospective study based on evaluation of data from Serviço de Cirurgia, Neurologia and Consult de Neurology processes, between 1990-2003, of 15 patients submitted to total thymectomy. RESULTS: 15 patients, aged 17 to 72, 11 female and 4 male. Miastenia Gravis was the main indication for surgery, for uncontrollable symptoms or suspicion of thymoma. In patients with myasthenia, surgery was accomplish after compensation of symptoms. There weren't post-surgery complications. Pathology were divided in thymic hyperplasia and thymoma. Miastenia patients have there symptoms diminished or stable with reduction or cessation of medical therapy. CONCLUSIONS: Miastenia was the most frequent indication for thymectomy. Surgery was good results, with low morbimortality, as long as the protocols are respected.

The Impact of Multifocal Intraocular Lens in Retinal Imaging with Optical Coherence Tomography

Multifocal intraocular lenses (MF IOLs) have concentric optical zones with different dioptric power, enabling patients to have good visual acuity at multiple focal points. However, several optical limitations have been attributed to this particular design. The purpose of this study is to access the effect of MF IOLs design on the accuracy of retinal optical coherence tomography (OCT). Cross-sectional study conducted at the Refractive Surgery Department of Central Lisbon Hospital Center. Twenty-three eyes of 15 patients with a diffractive MF IOL and 27 eyes of 15 patients with an aspheric monofocal IOL were included in this study. All patients underwent OCT macular scans using Heidelberg Spectralis®. Macular thickness and volume values and image quality (Q factor) were compared between the two groups. There were no statistically significant differences between both groups regarding macular thickness or volume measurements. Retinal OCT image quality was significantly lower in the MF IOL group (p < 0.01). MF IOLs are associated with a significant decrease in OCT image quality. However, this fact does not seem to compromise the accuracy of spectral domain OCT retinal measurements.

Implementation of robotic laparoscopic cholecystectomy in a university hospital.

BACKGROUND: Robot surgery is a further step towards new potential developments in minimally invasive surgery. Surgeons must keep abreast of these new technologies and learn their limits and possibilities. Robot-assisted laparoscopic cholecystectomy has not yet been performed in our institution. The purpose of this report is to present the pathway of implementation of robotic laparoscopic cholecystectomy in a university hospital. METHODS: The Zeus(R) robot system was used. Experimental training was performed on animals. The results of our experimental training allowed us to perform our first two clinical cases. RESULTS: Robot arm set-up and trocar placement required 53 and 35 minutes. Operative time were 59 and 45 minutes respectively. The overall operative time was 112 and 80 minutes, respectively. There were no intraoperative complications. Patients were discharged from the hospital after an overnight stay. CONCLUSION: Robotic laparoscopic cholecystectomy is safe and patient recovery similar to those of standard laparoscopy. At present, there are no advantages of robotic over conventional surgery. Nevertheless, robots have the potential to revolutionise the way surgery is performed. Robot surgery is not reserved for a happy few. This technology deserves more attention because it has the potential to change the way surgery is performed.

Regional Advisory Committee on Cancer - Report on Endocrine Cancer (September 2004) (PDF 144 KB)

There is already a good infrastructure for the management of endocrine cancer in Northern Ireland but to develop and strengthen it we recommend the following: • Increasing the already close cooperation between the individual parts of the service for endocrine cancer by use of shared protocols for assessment and follow up: • The main hub of management should remain at the RGH focussed on The Regional Centre for Endocrinology and Diabetes and the Endocrine Surgery department where there has been a long-term interest in the management of these patients. This includes a close working relationship between the endocrinologists and surgeon at the Belfast City Hospital. • This does not suggest that current developments of shared follow-up should not be encouraged. They should but with the provision of adequately resourced registers to allow adequate audit and to ensure adequate assessment of follow-up attendance. The issues regarding informed consent for such registers are currently being discussed for all forms of cancer. In the rarer conditions follow-up should remain central to allow adequate numbers and experience to maintain internationally recognisable outcomes and to allow training of future specialists to continue åÊ

Salvage treatment for venous aneurysm complicating vascular access arteriovenous fistula: use of an exoprosthesis to reinforce the vein after aneurysmorrhaphy.

OBJECTIVES: We report a new salvage technique for treating venous aneurysms (VAs) complicating vascular access arteriovenous fistula (AVF) using externally reinforced venous aneurysmorrhaphy. DESIGN: A retrospective study over a 20-month period from a single centre. PATIENTS: Patients presenting to the vascular surgery department, Bordeaux University Hospital for revision of a vascular access AVF were included. METHODS: Reinforced venous aneurysmorrhaphy consisted in removal of redundant vessel wall followed by reinforcement using an external prosthetic graft. Patency, diameter and flow were assessed by duplex ultrasound at 1, 6 and 12 months after salvage. RESULTS: Thirty-eight eligible patients were identified. Five were excluded because VA was associated with central vein stenosis; the remaining 33 underwent salvage. Indications were rapidly expanding or painful VA in seven cases; VA with frequent bleeding or damaged overlying skin in eight; VA in close relation to a stenosis in two; and VA associated with high-flow rate in 16. Cannulation was attempted after 30 days. Mean follow-up time was 12 S.D. 5 months (range: 4-22). Two repaired AVFs failed. Primary 1-year patency was 93%. No aneurysm or infection occurred. Reduction of high flow was successful in 12 of 16 patients. The remaining four required re-operation. CONCLUSIONS: Reinforced venous aneurysmorrhaphy is effective in controlling venous dilation and achieving patency. Reduction of high-flow rates was not always achieved. Further study is needed to evaluate long-term efficacy of this treatment.

Retrospective clinicopathological study of 418 odontogenic cysts

Objectives: To determine the relative incidence of odontogenic cysts and to identify the main clinicopathological features among patients treated in the Oral Surgery Department of the Dental Clinic of the University of Barcelona (Spain). Study design: A retrospective observational study was made of 418 odontogenic cysts diagnosed in 380 patients included in the database of 1235 histopathological diagnoses. The subjects were treated in the Master degree program of Oral Surgery and Implantology of the University of Barcelona in the period 1997-2006. The following variables were recorded: gender, age, clinical characteristics of the lesions (size and location), radiological features, duration, treatment, complications and relapses. A descriptive analysis was made of the study variables, using the SPSS version 15.0. Results: The incidence of odontogenic cysts was 33.8%. The mean patient age at appearance of the lesion was 42 years (range 7-83). The cysts were slightly more prevalent in males (58.4%). The lesion size ranged from 2-60 mm, with a mean size of 18.4 mm. The most frequent diagnosis was radicular cyst (50.2%). The most common location of the odontogenic cysts was in the mandible (61.5%), particularly the lower third molar region (36.8%). Conclusions: The most frequently diagnosed lesion was the radicular cyst. Odontogenic cysts were seen to be slightly more prevalent in males, and showed a high mandibular incidence. Knowledge of the biological and histological behavior of odontogenic cysts and their frequency are key aspects for ensuring early detection and adequate treatment.

Free Flap Monitoring. Using Tissue Oxygen Measurement and Positron Emission Tomography

Aims:This study was carried out to evaluate the feasibility of two different methods to determine free flap perfusion in cancer patients undergoing major reconstructive surgery. The hypotheses was that low perfusion in the flap is associated with flap complications. Patients and methods: Between August 2002 and June 2008 at the Department of Otorhinolaryngology – Head and Neck Surgery, Department of Surgery, and at the PET Centre, Turku, 30 consecutive patients with 32 free flaps were included in this study. The perfusion of the free microvascular flaps was assessed with positron emission tomography (PET) and radioactive water ([¹⁵O] H₂O) in 40 radiowater injections in 33 PET studies. Furthermore, 24 free flaps were monitored with a continuous tissue oxygen measurement using flexible polarographic catheters for an average of three postoperative days. Results: Of the 17 patients operated on for head and neck (HN) cancer and reconstructed with 18 free flaps, three re-operations were carried out due to poor tissue oxygenation as indicated by p_tiO₂ monitoring results and three other patients were reoperated on for postoperative hematomas in the operated area. Blood perfusion assessed with PET (BF_PET) was above 2.0 mL / min / 100 g in all flaps and a low flap-to-muscle BFPET ratio appeared to correlate with poor survival of the flap. Survival in this group of HN cancer patients was 9.0 months (median, range 2.4-34.2) after a median follow-up of 11.9 months (range 1.0-61.0 months). Seven HN patients of this group are alive without any sign of recurrence and one patient has died of other causes. All of the 13 breast reconstruction patients included in the study are alive and free of disease at a median follow-up time of 27.4 months (range 13.9-35.7 months). Re-explorations were carried out in three patients due data provided by p_tiO₂ monitoring and one re-exploration was avoided on the basis of adequate blood perfusion assessed with PET. Two patients had donorsite morbidity and 3 patients had partial flap necrosis or fat necrosis. There were no total flap losses. Conclusions: P_tiO₂ monitoring is a feasible method of free flap monitoring when flap temperature is monitored and maintained close to the core temperature. When other monitoring methods give controversial results or are unavailable, [₁₅O] H₂O PET technique is feasible in the evaluation of the perfusion of the newly reconstructed free flaps.

Toimintaprosessin kehittäminen sairaalaympäristössä teollisuustalouden menetelmin

Työn tavoitteena on tutkia reaaliaikaisen sanelunpurun vaikuttavuutta ja kannattavuutta. Reaaliaikaisen sanelunpurun vaikuttavuuden tarkastelun pohjana käytetään teollisuustalouden puolella tunnettuja ja yrityksissä laajasti käytössä olevia ajatusmalleja, kuten Leania ja Six Sigmaa. Lean –ajattelu perustuu läpimenoajan nopeuttamiseen, hukkaa ja ei lisäarvoa luovien vaiheiden eliminoimisella. Six Sigma keskittyy taas laatuun, jolloin tuote ja palveluvirheitä karsitaan. Lisäksi teoriaosassa käsitellään palveluiden ulkoistamista, tietosuojaa ja palkkakustannusten rakennetta. Empiriaosassa kuvataan kirurgianpoliklinikan ja leikkausosaston prosesseja. Prosesseissa keskitytään nykytilan sekä reaaliaikaisen sanelunpurun vaikutuksiin. Prosessien kuvaamisella saadaan tietoa toiminnan ongelmista ja kehittämiskohteista. Henkilökunnan haastatteluin selvitettiin sanelujonon vaikutuksia sekä kokemuksia ulkoistamisesta. Kustannusanalyysin avulla selvitettiin ulkoistamisen kannattavuutta reaaliaikaisessa sanelunpurussa. Työn tuloksena saatiin vaikuttavuus tarkastelu reaaliaikaisesta sanelunpurusta sekä ulkoistamisen kannattavuudesta. Prosessien kuvaaminen osoittaa, että useissa prosessin eri vaiheissa sanelujen puuttuminen aiheuttaa kustannuksia ja vaikuttaa henkilökunnan työhön. Kustannusanalyysin pohjalta sanelunpurun ulkoistaminen todettiin kannattavaksi. Jatkossa sanelunpurun ulkoistamisessa tulee kiinnittää huomiota siihen, mitkä osat sanelunpurkuprosessista halutaan ulkoistaa. Sähköisten järjestelmien kehittyminen vaikuttaa osaltaan tähän päätökseen. Lisäksi suoritepohjaisen hinnoittelun kehittäminen on tärkeä osa sanelunpurkuprosessin tehokkuutta.
