Background It has been clearly shown that after elective colorectal surgery patients benefit from multimodal perioperative care programs. The Dutch Institute for Health Care Improvement started a breakthrough project to implement a multimodal perioperative care program of enhanced recovery after surgery (ERAS). This pre/post noncontrolled study evaluated the success of large-scale implementation of the ERAS program for elective colonic surgery using the breakthrough series. Methods A total of 33 hospitals participated in this breakthrough project during 2005–2009. Each hospital performed a retrospective chart review to gather information on traditionally treated patients (pre-ERAS group, n  = 1,451). During the subsequent year patients were treated according to the ERAS program (ERAS group, n  = 1 034). Outcomes were length of stay (LOS), functional recovery, adherence to the protocol, and determinants of reduced LOS. Results Median LOS decreased significantly from 9 to 6 days ( p  < 0.001). In the ERAS group, functional recovery was reached within 3 days. Adherence to the protocol elements was high during the preoperative and perioperative phases but slightly lower during the postoperative phase. Younger age, female sex, American Society of Anesthesiologists grades I/II, and laparoscopic surgery were associated with decreased LOS. Care elements that positively influenced LOS were cessation of intravenous fluids and mobilization on postoperative day 1 and administration of laxatives postoperatively. Conclusions The ERAS program was successfully implemented in one-third of all Dutch hospitals using the breakthrough series. Participating hospitals reduced the LOS by a median 3 days and were able to improve their standard of care in elective colonic surgery.

Objective Colonic ischaemia is frequently observed in clinical practice. This study provides a novel insight into the pathophysiology of colon ischaemia/reperfusion (IR) using a newly developed human and rat experimental model. Design In 10 patients a small part of colon that had to be removed for surgical reasons was isolated and exposed to 60 min of ischaemia (60I) with/without different periods of reperfusion (30R and 60R). Tissue not exposed to IR served as control. In rats, colon was exposed to 60I, 60I/30R, 60I/120R or 60I/240R (n=7 per group). The tissue was snap-frozen or fixed in glutaraldehyde, formalin or methacarn fixative. Mucins were stained with Periodic Acid Schiff/Alcian Blue (PAS/AB) and MUC2/Dolichos biflorus agglutinin (DBA). Bacteria were studied using electron microscopy (EM) and fluorescent in situ hybridisation (FISH). Neutrophils were studied using myeloperoxidase staining. qPCR was performed for MUC2, interleukin (IL)-6, IL-1β and tumour necrosis factor α. Results In rats, PAS/AB and MUC2/DBA staining revealed mucus layer detachment at ischaemia which was accompanied by bacterial penetration (in EM and FISH). Human and rat studies showed that, simultaneously, goblet cell secretory activity increased. This was associated with expulsion of bacteria from the crypts and restoration of the mucus layer at 240 min of reperfusion. Inflammation was limited to minor influx of neutrophils and increased expression of proinflammatory cytokines during reperfusion. Conclusions Colonic ischaemia leads to disruption of the mucus layer facilitating bacterial penetration. This is rapidly counteracted by increased secretory activity of goblet cells, leading to expulsion of bacteria from the crypts as well as restoration of the mucus barrier.

Background Two healthcare innovations were successfully implemented using different implementation strategies. First, a Short Stay Programme for breast cancer surgery (MaDO) was implemented in four early adopter hospitals, using a hospital-tailored implementation strategy. Second, the Enhanced Recovery After Surgery (ERAS) programme for colonic surgery was implemented in 33 Dutch hospitals, using a generic breakthrough implementation strategy. Both strategies resulted in a shorter hospital length of stay without a decrease in quality of care. Currently, it is unclear to what extent these innovative programmes and their results have been sustained three to five years following implementation. The aim of the sustainability of healthcare innovations (SUSHI) study is to analyse sustainability and its determinants using two implementation cases. Methods This observational study uses a mixed methods approach. The study will be performed in 14 hospitals in the Netherlands, from November 2010. For both implementation cases, the programme aspects and the effects will be evaluated by means of a follow-up measurement in 160 patients who underwent breast cancer surgery and 300 patients who underwent colonic surgery. A policy cost-effectiveness analysis from a societal perspective will be performed prospectively for the Short Stay Programme for breast cancer surgery in 160 patients. To study determinants of sustainability key professionals in the multidisciplinary care processes and implementation change agents will be interviewed using semi-structured interviews. Discussion The concept of sustainability is not commonly studied in implementation science. The SUSHI study will provide insight in to what extent the short-term implementation benefits have been maintained and in the determinants of long-term continuation of programme activities.

Nutritional depletion increases the risk for postoperative complications. The intestinal barrier may be important in the underlying pathophysiologic mechanism. In this study, 26 patients were evaluated to determine whether nutritional depletion was related to gut integrity and intestinal morphology. Nutritional depletion was estimated by calculating percentage ideal body weight (PIB) or percentage ideal fat free mass (PIFFM). To assess gut integrity, a lactulose/mannitol (L/M) test was performed. Duodenal biopsies were taken, and villous height, crypt depth, number of IgA-producing plasma cells, intraepithelial lymphocytes (IELs), and proliferating index were determined. The L/M ratio was increased, and villous height was decreased in depleted patients. Depletion was not associated with differences in the number of immune cells or proliferating index. The number of IgA-producing plasma cells was positively correlated with the L/M ratio. This study shows that nutritional depletion is associated with increased intestinal permeability and a decrease in villous height.

Background A quality improvement collaborative is an intensive project involving a combination of implementation strategies applied in a limited “breakthrough” time window. After an implementation project, it is generally difficult to sustain its success. In the current study, sustainability was described as maintaining an implemented innovation and its benefits over a longer period of time after the implementation project has ended. The aim of the study was to explore potentially promising strategies for sustaining the Enhanced Recovery After Surgery (ERAS) programme in colonic surgery as perceived by professionals, three to six years after the hospital had successfully finished a quality improvement collaborative. Methods A qualitative case study was performed to identify promising strategies to sustain key outcome variables related to the ERAS programme in terms of adherence, time needed for functional recovery and hospital length of stay (LOS), as achieved immediately after implementation. Ten hospitals were selected which had successfully implemented the ERAS programme in colonic surgery (2006–2009), with success defined as a median LOS of 6 days or less and protocol adherence rates above 70%. Fourteen semi-structured interviews were held with eighteen key participants of the care process three to six years after implementation, starting with the project leader in every hospital. The interviews started by confronting them with the level of sustained implementation results. A direct content analysis with an inductive coding approach was used to identify promising strategies. The mean duration of the interviews was 37 minutes (min 26 minutes – max 51 minutes). Results The current study revealed strategies targeting professionals and the organisation. They comprised internal audit and feedback on outcomes, small-scale educational booster meetings, reminders, changing the physical structure of the organisation, changing the care process, making work agreements and delegating responsibility, and involving a coordinator. A multifaceted self-driven promising strategy was applied in most hospitals, and in most hospitals promising strategies were suggested to sustain the ERAS programme. Conclusions Joining a quality improvement collaborative may not be enough to achieve long-term normalisation of transformed care, and additional investments may be needed. The findings suggest that certain post-implementation strategies are valuable in sustaining implementation successes achieved after joining a quality improvement collaborative.

Background The potential barriers and facilitators to change should guide the choice of implementation strategy. Implementation researchers believe that existing methods for the evaluation of potential barriers and facilitators are not satisfactory. Discrete choice experiments (DCE) are relatively new in the health care sector to investigate preferences, and may be of value in the field of implementation research. The objective of our study was to investigate the complementary value of DCE for the evaluation of barriers and facilitators in implementation research. Methods Clinical subject was the implementation of the guideline for breast cancer surgery in day care. We identified 17 potential barriers and facilitators to the implementation of this guideline. We used a traditional questionnaire that was made up of statements about the potential barriers and facilitators. Respondents answered 17 statements on a five-point scale ranging from one (fully disagree) to five (fully agree). The potential barriers and facilitators were included in the DCE as decision attributes. Data were gathered among anaesthesiologists, surgical oncologists, and breast care nurses by means of a paper-and-pencil questionnaire. Results The overall response was 10%. The most striking finding was that the responses to the traditional questionnaire hardly differentiated between barriers. Forty-seven percent of the respondents thought that DCE is an inappropriate method. These respondents considered DCE too difficult and too time-consuming. Unlike the traditional questionnaire, the results of a DCE provide implementation researchers and clinicians with a relative attribute importance ranking that can be used to prioritize potential barriers and facilitators to change, and hence to better fine-tune the implementation strategies to the specific problems and challenges of a particular implementation process. Conclusion The results of our DCE and traditional questionnaire would probably lead to different implementation strategies. Although there is no 'gold standard' for prioritising potential barriers and facilitators to the implementation of change, theoretically, DCE would be the method of choice. However, the feasibility of using DCE was less favourable. Further empirical applications should investigate whether DCE can really make a valuable contribution to the implementation science.

Background Despite the increased attention for assessing the effectiveness of implementation strategies, most implementation studies provide little or no information on its associated costs. The focus of the current study was to provide a detailed report of the resource use and costs associated with implementation of a short stay programme for breast cancer surgery in four Dutch hospitals. Methods The analysis was performed alongside a multi-centre implementation study. The process of identification, measurement and valuation of the implementation activities was based on recommendations for the design, analysis and reporting of health technology assessments. A scoring form was developed to prospectively determine the implementation activities at professional and implementation expert level. A time horizon of 5 years was used to calculate the implementation costs per patient. Results Identified activities were consisted of development and execution of the implementation strategy during the implementation project. Total implementation costs over the four hospitals were €83.293. Mean implementation costs, calculated for 660 patients treated over a period of 5 years, were €25 per patient. Subgroup analyses showed that the implementation costs ranged from €3.942 to €32.000 on hospital level. From a local hospital perspective, overall implementation costs were €21 per patient, after exclusion of the costs made by the expert centre. Conclusions We provided a detailed case description of how implementation costs can be determined. Notable differences in implementation costs between hospitals were observed.

The rate of complications in immediate breast reconstruction is in 15% to 20% due to partial loss of the mastectomy skin flaps. In the case of skin necrosis or ischemia, a therapy that reduces skin loss could be of additional benefit. Hyperbaric oxygen has been used to treat compromised flaps and grafts, an indication recognized and reimbursed according to the Undersea and Hyperbaric Medical Society (UHMS). So far, hyperbaric oxygen has not been previously reported as therapy for full-thickness breast skin flap necrosis on patients with a direct reconstruction with silicone implants after a skin-sparing mastectomy. This report presents such a case, in which a 52-year-old woman carrier of the BRCA2 mutation gene was successfully treated with hyperbaric oxygen therapy.

Background: A comprehensive evidence base for perioperative care in upper gastrointestinal (GI) surgery is lacking. Little is known about the routines currently practiced in the absence of such evidence. We describe postoperative practice after gastric resections in five northern European countries. Method and Setting: Questionnaire survey in all major digestive surgical centres in Scotland, the Netherlands, Denmark, Sweden and Norway. Results: 76% of all centres (n = 200/263) responded. Routines varied extensively both nationally and between countries. No uniformity was traced although a conservative trend was noticeable in the use of nasogastric decompression tubes and ‘nil-by-mouth’ regimens. Nutritional support during the first 5 days is generally offered in Denmark, but not in Scotland. Drinking at will is generally allowed in Denmark and Norway by the first postoperative day. Eating at will is uniformly restricted. Conclusion: The paucity of evidence is reflected by the marked heterogeneity in practice. Large groups of patients may be treated suboptimally. Best perioperative care for these patients must be defined and documented. Especially, the role of early oral intake at will in upper GI surgery needs to be clarified by sufficiently powered trials.
