Death and injury on duty- a study of South African police officers

Objectives. Sections of contemporary South African society are characterised by high levels of crime and interpersonal conflict. The South African Police Service (SAPS) is in the front line, with many deaths and injuries occuring among serving officers in recent years. The circumstances and nature of the injuries sustained by these officers have received little attention in the medical literature.Design. A retrospective review of all injured SAPS members was undertaken at a single level one trauma centre in Johannesburg between June 1993 and June 2002. The following factors were recorded: demographics, mechanism and anatomical site of injury, mode of transportation to hospital, whether personal protection had been used, mortality, and return to work.Results. One hundred and thirty-four SAPS personnel were admitted over a 9-year period. The majority (95%) were male and the median age was 31 years. One hundred and thirty two were on duty and two were in transit to a place of duty when injured. Ninety-two (69%) were injured by gunshot, (including 3 attempted suicides and 9 injuries due to negligent discharge), 2 members were stabbed, 31 were involved in motor vehicle accidents, 2 in motorbike accidents, 1 member was struck by a car while directing traffic, 3 officers were injured by falls from a height, 2 members were injured in helicopter crashes, and 1 member required treatment for gas inhalation. Documentation on whether some form of personal protection was worn at the time of injury was only available for 43 of the 92 cases of gunshot wounds (47%); of these, only 15 (35%) were wearing a bulletproof vest. Use or non-use of a seat belt was documented by hospital staff for only 6 of the 31 officers (19%) injured in motor vehicle accidents. None of the 6 officers had been restrained by a seatbelt. Nineteen SAPS personnel (14%) died of their injuries, but the majority of surviving members returned to duty.Conclusion. There is an unacceptably high level of violence in South African society today and SAPS members regularlyhave to deal with dangerous or violent situations. There is a clear need to introduce a reporting system within the SAPS to record the use of personal protection by officers. Education needs to target SAPS members in order to enhance their use of personal protection. There is a further need to design and implement personal protection that will be universally acceptable by SAPS members

Safety and efficacy of non-steroidal anti-inflammatory drugs to reduce ileus after colorectal surgery

Background: Ileus is common after elective colorectal surgery, and is associated with increased adverse events and prolonged hospital stay. The aim was to assess the role of non-steroidal anti-inflammatory drugs (NSAIDs) for reducing ileus after surgery. Methods: A prospective multicentre cohort study was delivered by an international, student- and trainee-led collaborative group. Adult patients undergoing elective colorectal resection between January and April 2018 were included. The primary outcome was time to gastrointestinal recovery, measured using a composite measure of bowel function and tolerance to oral intake. The impact of NSAIDs was explored using Cox regression analyses, including the results of a centre-specific survey of compliance to enhanced recovery principles. Secondary safety outcomes included anastomotic leak rate and acute kidney injury. Results: A total of 4164 patients were included, with a median age of 68 (i.q.r. 57\u201375) years (54\ub79 per cent men). Some 1153 (27\ub77 per cent) received NSAIDs on postoperative days 1\u20133, of whom 1061 (92\ub70 per cent) received non-selective cyclo-oxygenase inhibitors. After adjustment for baseline differences, the mean time to gastrointestinal recovery did not differ significantly between patients who received NSAIDs and those who did not (4\ub76 versus 4\ub78 days; hazard ratio 1\ub704, 95 per cent c.i. 0\ub796 to 1\ub712; P = 0\ub7360). There were no significant differences in anastomotic leak rate (5\ub74 versus 4\ub76 per cent; P = 0\ub7349) or acute kidney injury (14\ub73 versus 13\ub78 per cent; P = 0\ub7666) between the groups. Significantly fewer patients receiving NSAIDs required strong opioid analgesia (35\ub73 versus 56\ub77 per cent; P < 0\ub7001). Conclusion: NSAIDs did not reduce the time for gastrointestinal recovery after colorectal surgery, but they were safe and associated with reduced postoperative opioid requirement
