Performance improvement through best practice team management: human factors in complex trauma.

Human factors or non-technical skills are now commonplace in the medical literature, having taken the lead from the airline and nuclear industries and more recently Formula One motor racing. They have been suggested as playing a vital role in the success of the trauma teams in recent conflicts. This article outlines the background to human factors, referring to early papers and reports and also outlines high profile cases that highlight their importance. We then describe the importance of human factors in the deployed setting and some of the lessons that have been learnt from current conflicts.

Optimising communication in the damage control resuscitation -- Damage Control Surgery sequence in major trauma management.

Damage Control Resuscitation and Damage Control Surgery (DCR-DCS) is an approach to managing severely injured patients according to their physiological needs, in order to optimise outcome. Key to delivering DCR-DCS is effective communication between members of the clinical team and in particular between the surgeon and anaesthetist, in order to sequence and prioritise interventions. Although the requirement for effective communication is self-evident, the principles to achieving this can be forgotten and sub-optimal when unexpected problems arise at critical points during management of challenging cases. A system is described which builds on the 'World Health Organisation (WHO) safer surgery checklist' and formalises certain stages of communication in order to assure the effective passage of key points. We have identified 3 distinct phases: (i) The Command Huddle, once the patient has been assessed in the Emergency room; (ii) The Snap Brief, once the patient has arrived in the Operating Room but before the start of surgery; and (iii) The Sit-Reps, every 10 minutes for the entire theatre team to maintain situational awareness and allow effective anticipation and planning.

Human factors in decision making in major trauma in Camp Bastion, Afghanistan.

INTRODUCTION: The concentration of major trauma experience at Camp Bastion has allowed continuous improvements to occur in the patient pathway from the point of wounding to surgical treatment. These changes have involved clinical management as well as alterations to the physical layout of the hospital, training and decision making. Consideration of the human factors has been a major part of these improvements. METHODS: We describe the Camp Bastion patient pathway with the communication template that focused decision making at various key moments during damage control resuscitation and damage control surgery (DCR-DCS). This system identifies four key stages: 'command huddle', 'snap brief', 'sit-reps' (situation reports) and 'sign-out/debrief'. The attitude of staff to communication and decision making is also evaluated. RESULTS: Twenty cases admitted to Camp Bastion with battlefield injuries were studied from 6 September to 6 October 2012. Qualitative responses from 115 members of staff were collected. All patients were haemodynamically shocked with a median pH of 7.25 (range: 6.83-7.40) and a median of 18 units of mixed red cells and plasma were transfused. In 89% of instances, theatre staff were aware of what was required of them at the beginning of the case, 86% felt there were regular updates and 93% understood what was required of them as the case progressed. CONCLUSIONS: The evolution of the hospital at Camp Bastion has been a unique learning experience in the field of major trauma. The Defence Medical Services have responded with continuous innovation to optimise DCR-DCS for seriously injured patients. Together with the improvements in clinical care, a communication and decision making matrix was developed. Staff evaluation showed a high degree of satisfaction with the quality of communication.

Women's lung cancer mortality, socio-economic status and changing smoking patterns.

Mortality data from the OPCS Longitudinal Study were used to determine whether the conventional classification of married women by their husband's occupation under-estimates the extent of social differences in lung cancer among this group. Differences existed for social class measures but alternatives based on housing tenure and car access defined socio-economic differences wider than any other previously recorded for England and Wales: married women living in rented housing and without a car were two and a half times as likely to die from lung cancer than those in owner occupied housing with access to a car. In 1957 and 1974 mothers of children included in the 1958 cohort study showed parallel socio-economic differences in smoking patterns as well as in uptake and cessation rates. Data from the General Household Survey for 1982 similarly suggest that cigarette smoking is more sharply differentiated using household rather than occupational measures of class. This suggests that wide differences in mortality are likely to persist through the eighties and beyond.

Role of angiogenesis in benign, premalignant and malignant vulvar lesions.

OBJECTIVE: To investigate the presence of angiogenic factors in benign, premalignant and malignant vulvar lesions. STUDY DESIGN: Immunohistochemical demonstration of vascular endothelial growth factor (VEGF) and platelet-derived endothelial cell growth factor (PD-ECGF) in normal vulvar skin, lichen sclerosus, vulvar intraepithelial neoplasia (VIN) and vulvar cancer. RESULTS: VEGF was found in the majority of vulvar cancers but only a minority of VIN lesions. PD-ECGF was found in the majority of lesions. CONCLUSION: Demonstration of angiogenesis may suggest which preinvasive lesions will progress to invasive cancer.

Failure in the application of fragility fracture prevention guidelines.

INTRODUCTION: The cost of fragility fractures to the UK economy is predicted to reach £2.2 billion by 2025. We studied our hip fracture population to establish whether national guidelines on fragility fracture prevention were being followed, and whether high risk patients were identified and treated by local care services. METHODS: Data on a consecutive series of trauma hip fracture admissions were collected prospectively over 14 months. National Institute for Health and Care Excellence (NICE) and National Osteoporosis Guideline Group (NOGG) recommendations and FRAX(®) risk calculations were applied to patients prior to their admission with a new hip fracture. RESULTS: Overall, 94 patients were assessed against national guidelines. The mean population age was 77 years. Almost a quarter (22%) of patients had suffered a previous fragility fracture. The mean FRAX(®) ten-year probability of hip fracture was 7%. According to guidelines, 45% of the study population required treatment, 35% fulfilled criteria for investigation and reassessment, and 20% needed no further management. In practice, 27% received treatment, 4% had undergone dual energy x-ray absorptiometry and were untreated, and 69% had not been investigated and were untreated. In patients meeting intervention thresholds, only 33% of those who required treatment were receiving treatment in practice. CONCLUSIONS: In conjunction with NICE and NOGG recommendations, FRAX(®) was able to identify 80% of our fracture population as intermediate or high risk on the day of fracture. Correct management was evident in a third of cases with a pattern of inferior guideline compliance seen in a London population. There remains a lack of clarity over the duty of care in fragility fracture prevention.

Managing type II and type IV Lauge-Hansen supination external rotation ankle fractures: current orthopaedic practice.

INTRODUCTION: Differentiating supination external rotation (SER) type II and IV ankle injuries is challenging in the absence of a medial malleolar fracture or talar shift on radiographs. The accurate differentiation between a stable SER-II from an unstable SER-IV injury would allow implementation of the appropriate management plan from diagnosis. The aim of this study was to ascertain the practice of orthopaedic surgeons in dealing with these injuries. MATERIALS AND METHODS: A postal survey was undertaken on 216 orthopaedic consultants from three regions. RESULTS: In the presence of medial-sided clinical signs (tenderness, swelling, ecchymosis), 22% of consultants would perform surgical fixation. 53% would choose non-operative treatment and the majority would monitor these fractures through serial radiographs. The remaining 25% of consultants would perform an examination under anaesthesia (EUA; 15%), request stress radiographs (9%) or an MRI scan (1%). Without medial-sided signs, 85% would advocate non-operative treatment and, of these, 74% would perform weekly radiographs. Interestingly, 6% would perform immediate surgical fixation. Stress radiographs (6%) and EUAs (2%) were advocated in the remaining group of consultants. Foot and ankle surgeons utilised stress radiographs more frequently and were more likely to proceed to surgical fixation should talar shift be demonstrated. CONCLUSIONS: Clinical practice is varied amongst the orthopaedic community. This may lead to unnecessary surgery in SER-II injuries and delay in diagnosis and operative management of SER-IV injuries. We have highlighted the various investigative modalities available that may be used in conjunction with clinical signs to make a more accurate diagnosis.

"No one has ever asked for it back!" A survey assessing the fate of reusable external fixation equipment in mortuaries.

Technicians from one hundred and eighteen Human Tissue Authority (HTA) approved mortuaries licensed to perform post-mortems in England completed a telephone interview. All were questioned on whether they had contact with reusable external fixators, who was responsible for the removal, the number removed annually, and the destination of the fixator post-removal. Opinion was sought on how the return of the equipment could be better facilitated. Seventy-four of the technicians interviewed could remember seeing external fixation devices, but were unable to quantify how many were removed annually. Sixty-one of those questioned stated that they personally removed the fixator, three always requested an Orthopaedic surgeon to remove the device and five contacted a Nurse Specialist. Forty-eight stated that they returned the devices to their local Sterile Services Department or Orthopaedic department. Nine technicians always discarded the fixators, eight always left them with the body and two stored them in the mortuary. Many reusable external fixation devices are inappropriately disposed of each year due to a lack of knowledge and communication with Orthopaedic departments. Confusion also exists among some technicians over whether external fixation components should be treated as 'implants'. There is a need for clear guidelines to raise awareness and ensure the appropriate return of these high cost devices.

Inequalities in women's health: looking at mortality differentials using an alternative approach.

Data obtained from follow up of the 1971 census sample in the Office of Population Censuses and Surveys longitudinal study of England and Wales were used to look at women's mortality differentials at ages 15-59. Women were grouped by combining information on marital state, own occupation, husband's occupation (if married), economic activity, and indicators of household wealth (housing tenure and access to a car). Large groups were found with considerable differences in mortality. High mortality was associated with working in manual occupations and living in rented housing with no car in the household. In contrast, low mortality was associated with non-manual occupations and living in owner occupied housing with a car. Among married housewives and single women these extreme groups contributed 44% of expected deaths, the disadvantaged group experiencing death rates two and a half times that of the advantaged group. Smaller differences were found among married women with an occupational class. These findings are further evidence of the "health divide" in England and Wales and show that accurately to reflect the relation between a woman's life circumstances and mortality it is necessary to utilise other measures than those based solely on occupation.

Inequalities in women's health in England and Wales: mortality among married women according to social circumstances, employment characteristics and life-cycle stage.

"Data obtained from follow-up of the Office of Population Censuses and Surveys Longitudinal Study 1971 Census sample have been used to look at women's mortality differentials at ages 15-59 in England and Wales....In this paper we focus on married women and use age of youngest child as a measure of life-cycle stage. We relate this to whether the woman was a housewife, or was in full or part-time paid employment, so as to examine how these affect differences in mortality by social class. We find that socio-economic mortality differences persist irrespective of life-cycle stage.... Housewives married to men in manual occupations experienced death rates over one and a half times as high as those married to men in non-manual occupations. For women in employment the differences by husbands' social class are of a lesser magnitude.... Differences in the mortality of those in full and part-time work depend on the woman's own social class and are greater for non-manual than manual classes." (SUMMARY IN FRE AND ITA)
