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.

Burn prevention mechanisms and outcomes: pitfalls, failures and successes

Burns are responsible for significant mortality and morbidity worldwide and are among the most devastating of all injuries, with outcomes spanning the spectrum from physical impairments and disabilities to emotional and mental consequences. Management of burns and their sequelae even in well-equipped, modern burn units of advanced affluent societies remains demanding and extremely costly. Undoubtedly, in most low and middle income countries (LMICs) with limited resources and inaccessibility to sophisticated skills and technologies, the same standard of care is obviously not possible. Unfortunately, over 90% of fatal fire-related burns occur in developing or LMICs with South-East Asia alone accounting for over half of these fire-related deaths. If burn prevention is an essential part of any integrated burn management protocol anywhere, focusing on burn prevention in LMICs rather than treatment cannot be over-emphasized where it remains the major and probably the only available way of reducing the current state of morbidity and mortality. Like other injury mechanisms, the prevention of burns requires adequate knowledge of the epidemiological characteristics and associated risk factors, it is hence important to define clearly, the social, cultural and economic factors, which contribute to burn causation. While much has been accomplished in the areas of primary and secondary prevention of fires and burns in many developed or high-income countries (HICs) such as the United States due to sustained research on the epidemiology and risk factors, the same cannot be said for many LMICs. Many health authorities, agencies, corporations and even medical personnel in LMICs consider injury prevention to have a much lower priority than disease prevention for understandable reasons. Consequently, burns prevention programmes fail to receive the government funding that they deserve. Prevention programmes need to be executed with patience, persistence, and precision, targeting high-risk groups. Depending on the population of the country, burns prevention could be a national programme. This can ensure sufficient funds are available and lead to proper coordination of district, regional, and tertiary care centres. It could also provide for compulsory reporting of all burn admissions to a central registry, and these data could be used to evaluate strategies and prevention programmes that should be directed at behavioural and environmental changes which can be easily adopted into lifestyle. Particularly in LMICs, the emphasis in burn prevention should be by advocating change from harmful cultural practices. This needs to be done with care and sensitivity. The present review is a summary of what has already been accomplished in terms of burn prevention highlighting some of the successes but above all the numerous pitfalls and failures. Recognizing these failures is the first step towards development of more effective burn prevention strategies particularly in LMICs in which burn injury remains endemic and associated with a high mortality rate. Burn prevention is not easy, but easy or not, we have no options; burns must be prevented.

Spinal Cord Injury and Aging: Exploring the Unknown

ABSTRACT

We conducted a retrospective case-control study of falls over a four year period on a 30 bed neurorehabilitation unit at the Burke Rehabilitation Hospital to characterize the nature of falls and identify factors associated with falling. The most common diagnoses treated on the unit were traumatic spinal cord injury, brain injury, and multiple sclerosis; stroke patients are treated on another service. Falls represented 72 percent of all incident reports made to the Nursing Office during the study period. One hundred seventeen (117) falls occurred in 82 patients during a time when the unit census was 28,622 patient days, yielding a rate of 1,439 falls per 1,000 patient years. One hundred fourteen (114) patients admitted with no history of falling during the same period were selected randomly for comparison. Most falls were associated with no injury (n=96) or minor injury (n=18). The most significant injuries occurred in three cases with lacerations requiring sutures. Falls occurred with greatest frequency during the first and fourth quartiles of the hospital stay, during the evening and while bed transfers were being performed. No association between falling and patient age, sex, diagnosis, number of medications, use of sedating medications, presence of motor, visual or cognitive impairment or orthostatic hypotension was evident. An increased risk of falling was associated with physician orders for Posey restraints. The implication of these findings for falls prevention programs is discussed.

Systematic review of the use of prophylactic dressings in the prevention of pressure ulcers

This systematic review considers the evidence supporting the use of prophylactic dressings for the prevention of pressure ulcer. Electronic database searches were conducted on 25 July 2013. The searches found 3026 titles and after removal of duplicate records 2819 titles were scanned against the inclusion and exclusion criteria. Of these, 2777 were excluded based on their title and abstract primarily because they discussed pressure ulcer healing, the prevention and treatment of other chronic and acute wounds or where the intervention was not a prophylactic dressing (e.g. underpads, heel protectors and cushions). Finally, the full text of 42 papers were retrieved. When these 42 papers were reviewed, 21 were excluded and 21 were included in the review. The single high‐quality randomised controlled trial (RCT) and the growing number of cohort, weak RCT and case series all suggest that the introduction of a dressing as part of pressure ulcer prevention may help reduce pressure ulcer incidence associated with medical devices especially in immobile intensive care unit patients. There is no firm clinical evidence at this time to suggest that one dressing type is more effective than other dressings.     

High variability in the measurement of HIV primary prevention activities and outcomes

IntroductionWhile there is a global consensus on monitoring Human Immunodeficiency Virus (HIV) treatment progress, there has been less attention to the degree of consistency of the measurement of HIV prevention programmes—and the global prevention response is not on‐track to achieve 2020 goals. In this paper, we assess the degree of variability in primary prevention indicators selected by national strategic plans (NSPs) and global stakeholder monitoring and evaluation (M&E) strategies.MethodsWe obtained the most recent NSPs from low and middle income Joint United Nations Programme on HIV/AIDS (UNAIDS) Fast‐Track countries, and M&E documents from The Global Fund to Fight AIDS, Tuberculosis and Malaria (The Global Fund), President’s Emergency Plan for AIDS Relief (PEPFAR), UNAIDS, the Global HIV Prevention Coalition and the World Health Organization (WHO). We extracted HIV primary prevention indicators from each document, standardized and aggregated them by age/ sex, categorized indicators by topic, and evaluated the frequency of matched indicators between countries and stakeholders. Data were collected between February and April of 2019.ResultsTwenty‐one NSPs and five global stakeholder documents were assessed; 736 primary prevention indicators were identified; 284 remained following standardization and aggregation. NSPs contained from 3 to 48 primary prevention indicators, with an average of 23; categories included: HIV education and outreach (17.6%), testing (17.3%) and condom use (16.2%). Of unique national indicators, only 34% was shared between two or more countries. Sixty‐nine per cent was applied in a single country only. 56% of NSP indicators did not appear in any global stakeholder document. Conversely, 42% of global indicators did not appear in any surveyed NSPs. Within global indicators, 63% was only measured by one global body, and no single indicator was measured by all five.ConclusionsThese analyses reveal a lack of consensus both between and within countries’ and global stakeholders'' measurement of HIV prevention. Though some variability is expected, these findings point to a need to refocus attention on achieving greater consensus on a global measurement framework for HIV prevention.     

Potential Use of Vaccines in the Primary Prevention of Breast Cancer in High-Risk Patients

Cancer vaccines are an emerging therapeutic and prophylactic modality that may play a more important role in cancer prevention and treatment in the future. Therapeutic cancer vaccines are designed to generate a targeted, immune-mediated antitumor response. Successful prophylactic vaccines are those against oncogenic viral infections, such as the human papillomavirus and cervical cancer. However, a tough challenge for the majority of tumor vaccines is the self-nature of tumor antigens. Ongoing studies are investigating methods to enhance vaccine strategies including immune-modulating agents. The present review analyzes the potential use of vaccines in the primary prevention of breast cancer, focusing on the recent extension of vaccine target selection to self-proteins that are overexpressed during the early stages of tumor development but whose expression no longer occurs as we age, a feature that may avoid clinically significant autoimmune sequelae.     

社区骨质疏松症的综合防治

随着人口老龄化程度的加剧,骨质疏松症患者的数量逐年上升,由此导致老年人致残、致死的人数增加,给家庭和社会带来沉重的负担。目前,在大型综合医院对骨质疏松的治疗比较规范,但在社区医院对于骨质疏松症的诊治仍然存在认知上的差异。面对社区骨质疏松症认知诊治率偏低的问题,我们应积极强化对社区全科医生的培训,使其对骨质疏松症的认知和诊治水平得到提升,充分发挥社区全科医生的健康守门人作用,进一步普及防治骨质疏松症的健康知识,提高居民对骨质疏松症的防治意识,降低骨质疏松性骨折的发生率,提高其生存质量。     

CT angiography of the coronary arteries

There is insufficient knowledge about secondary prevention after coronary artery bypass grafting (CABG). Most of it is gathered from patients suffering from myocardial infarction and angina pectoris, only a minority of whom have undergone CABG. Whereas it seems clear that these patients should give up smoking and reduce low‐density lipoprotein (LDL) cholesterol, there is uncertainty about the optimal antiplatelet regimen and antithrombotic treatment. There are some data indicating the benefit of behaviour modification. There is room for improvement and more knowledge when it comes to secondary prevention after CABG.     

HIV sexual transmission risks in the context of clinical care: a prospective study of behavioural correlates of HIV suppression in a community sample,Atlanta, GA,USA

Introduction

Antiretroviral therapy (ART) improves the health of people living with HIV and has the potential to reduce HIV infectiousness, thereby preventing HIV transmission. However, the success of ART for HIV prevention hinges on sustained ART adherence and avoiding sexually transmitted infections (STI).

Objectives

To determine the sexual behaviours and HIV transmission risks of individuals with suppressed and unsuppressed HIV replication (i.e., viral load).

Methods

Assessed HIV sexual transmission risks among individuals with clinically determined suppressed and unsuppressed HIV. Participants were 760 men and 280 women living with HIV in Atlanta, GA, USA, who completed behavioural assessments, 28-daily prospective sexual behaviour diaries, one-month prospective unannounced pill counts for ART adherence, urine screening for illicit drug use and medical record chart abstraction for HIV viral load.

Results

Individuals with unsuppressed HIV demonstrated a constellation of behavioural risks for transmitting HIV to uninfected sex partners that included symptoms of STI and substance use. In addition, 15% of participants with suppressed HIV had recent STI symptoms/diagnoses, indicating significant risks for sexual infectiousness despite their HIV suppression in blood plasma. Overall, 38% of participants were at risk for elevated sexual infectiousness and just as many engaged in unprotected sexual intercourse with non-HIV-infected partners.

Conclusions

Implementation strategies for using HIV treatments as HIV prevention requires enhanced behavioural interventions that extend beyond ART to address substance use and sexual health that will otherwise undermine the potential preventive impact of early ART.     

Wounding,shock and stress lesions of the upper gastrointestinal tract

This retrospective study included 2532 wounded, of whom 354 (14 per cent) were treated in surgical intensive care units. In 32 patients, 1.3 per cent of all admissions, upper gastrointestinal bleeding was detected. It occurred on average 8.9 days (3–21 days) after the wounding or surgical procedure in severely injured patients and those treated in intensive care units, respectively (32 of 354 patients, 9.0 per cent). All patients received different analgesic drugs and 17 of a group that presented with bleeding were given psychotropic agents as well. The majority of patients (96.3 per cent) were administered H₂-receptor antagonists as prophylaxis against stress ulcer disease. There was a statistically significant difference between these patients treated with H₂-receptor antagonists and those on no prophylactic therapy. No statistically significant difference was found between cimetidine and ranitidine in terms of their efficacy. Endoscopic examination revealed multiple bleeding gastric and duodenal erosions. The lesions were most commonly located in the corpus of the stomach. In the majority of patients (56.25 per cent), the haemorrhage stopped spontaneously and rebleeding presented in four of 32 (12.5 per cent) patients. Of 354 patients treated in intensive care units, five (1.4 per cent) had to be operated on because of bleeding arrest. Despite all therapeutic and surgical procedures undertaken, five of 32 (15.6 per cent) patients died.

Completing the Audit Cycle: Comparison of Cardiac Risk Factor Management in Patients with Intermittent Claudication in Two Time Periods

AIM: The first line treatment of patients with intermittent claudication (IC) is to prolong life via cardiac risk factor management. We aimed to compare current standards of secondary prevention with those in a previously published audit. METHODS: Risk factor data was prospectively collated on 304 consecutive new referrals attending the claudication clinic over a 1-year period (2004/2005) and compared to the 104 patients assessed in 2000. RESULTS: In 2004/5 30%, (n=91) of patients did not have a diagnosis of IC confirmed (p<0.01). The use of antiplatelet therapy remained static at 73%. Statin therapy increased in 2004/5 (62% versus 38%, p<0.01) but blood pressure control remained poor with 65% failing to achieve the target levels. Smoking cessation therapy continues to be offered to a minority of patients and 17% of patients have previously undiagnosed diabetes in 2004/2005 (p-value 0.353). The number of patients who have been advised to increase physical activity significantly has fallen from 15% to 2% in the 2004/5 (p<0.01). CONCLUSIONS: Difficulties exist in diagnosing intermittent claudication in primary care and cardiac risk factor management continues to be sub-optimally managed.     

Stress and the schoolteacher

This paper examines the manifestations, effects, prevalence and origins of stress in schoolteachers. Evidence suggests that many teachers find their work stressful, that there is a correlation between perceived stress and the experience of psychological and physical symptoms, but that as a group teachers do not have an increased incidence of psychiatric or physical disorders. Possible coping strategies to reduce teacher stress are discussed.
