A multimodal infection control and patient safety intervention to reduce surgical site infections in Africa: a multicentre, before-after, cohort study.

BACKGROUND: Surgical site infections (SSIs) are the most frequent health-care-associated infections in developing countries. Specific prevention measures are highly effective, but are often poorly implemented. We aimed to establish the effect of a multimodal intervention on SSIs in Africa. METHODS: We did a before-after cohort study, between July 1, 2013, and Dec 31, 2015, at five African hospitals. The multimodal intervention consisted of the implementation or strengthening of multiple SSI prevention measures, combined with an adaptive approach aimed at the improvement of teamwork and the safety climate. The primary outcome was the first occurrence of SSI, and the secondary outcome was death within 30 days post surgery. Data on adherence to SSI prevention measures were prospectively collected. The intervention effect on SSI risk and death within 30 days post surgery was assessed in a mixed-effects logistic regression model, after adjustment for key confounders. FINDINGS: Four hospitals completed the baseline and follow-up; three provided suitable (ie, sufficient number and quality) data for the sustainability period. 4322 operations were followed up (1604 at baseline, 1827 at follow-up, and 891 in the sustainability period). SSI cumulative incidence significantly decreased post intervention, from 8·0% (95% CI 6·8-9·5; n=129) to 3·8% (3·0-4·8; n=70; p<0·0001), and this decrease persisted in the sustainability period (3·9%, 2·8-5·4; n=35). A substantial improvement in compliance with prevention measures was consistently observed in the follow-up and sustainability periods. The likelihood of SSI during follow-up was significantly lower than pre-intervention (odds ratio [OR] 0·40, 95% CI 0·29-0·54; p<0·0001), but the likelihood of death was not significantly reduced (0·72, 0·42-1·24; p=0·2360). INTERPRETATION: Implementation of our intervention is feasible in African hospitals. Improvement was observed across all perioperative prevention practices. A significant effect on the overall SSI risk was observed, but with some heterogeneity between sites. Further large-scale experimental studies are needed to confirm these results and to improve the sustainability and long-term effect of such complex programmes.

Traumatic tracheostomy and spent bullet aspiration after a gunshot injury: a case report.

Penetrating tracheal injuries are rare. Even rarer is the finding of intrabronchial foreign bodies caused by penetrating objects. We report a patient who experienced a gunshot injury to the trachea and mandible. The tracheal wound was debrided and used as a tracheostomy; a spent bullet in the bronchial tree was missed on initial evaluation but later successfully retrieved bronchoscopically. Spent bullet aspiration is a very rare occurrence. A careful examination of radiographs is essential to aid with the diagnosis. Flexible bronchoscopy is the best means of bullet retrieval. Management of any associated injuries is made easier after the airway is secured.

Strangulated paraumbilical hernia-An unusual complication of a Meckel's diverticulum.

INTRODUCTION: Meckel's diverticulum is the commonest congenital abnormality of the gastrointestinal tract. Most are asymptomatic but can rarely present with varies forms of intestinal obstruction. PRESENTATION OF CASE: We present an unusual case of an elderly African woman with a massive strangulated paraumbilical hernia as a complication from a Meckel's diverticulum. DISCUSSION: Meckel's diverticulum presenting as a strangulated paraumbilical hernia is uncommon and can be difficult to diagnose. It is often only found intraoperatively. Delay in referral due to poor access can potentially lead to adverse outcome. CONCLUSION: Although uncommon, a through clinical assessment is of paramount importance and timely operative intervention must occur in order to provide the best outcome for these patients.

Pedicled fasciocutaneous anterolateral thigh flap for the reconstruction of a large postoncologic abdominal wall resection defect: a case report.

The anterolateral thigh (ALT) flap has been used to cover defects between the proximal third of the leg and lower abdomen, and with modification, may cover epigastric defects. We used the ALT flap to cover a full-thickness defect of over half the anterior abdominal wall. We conclude that abdominal wall defects of large sizes can be successfully reconstructed using an appropriately designed ALT flap; a simple, single-stage effective reconstruction.
