A Growing Problem: Implications of Obesity on the Provision of Trauma Care

The lived experience of patients with obesity at a metropolitan public health setting

BACKGROUND

Patient-centred care models for acutely hospitalised people living with obesity are poorly understood and the quality of evidence low.

OBJECTIVE

The aim of this study was to explore and better understand the lived experience of people living with obesity, in the inpatient hospital context.

DESIGN

A qualitative methodology using Interpretative Phenomenological Analysis (IPA) was used. Data were collected via a single semi-structured interview with each participant.

SETTING AND PARTICIPANTS

The study was completed at a metropolitan public health service. Ten previously hospitalised patients who live with obesity were included.

RESULTS

Three main themes emerged: meeting physical care needs of people with obesity on hospital wards, interpersonal interactions between patients and healthcare professionals, and the psychosocial impact of being obese in the hospital setting. Priorities included timely provision of appropriate equipment and infrastructure design to meet care needs and facilitate better wellbeing. To improve patient experience, an emphasis on basic principles of quality care provision to enhance interpersonal interactions, along with improved awareness of the impact of weight bias and obesity stigma in healthcare are supported. Participants found hospitalisation stressful, but valued support from healthcare professionals regarding weight loss.

DISCUSSION

These data provide new insights in to the lived experience of people living with obesity in the hospital setting. Items which are low cost, such as appropriately sized chairs and gowns, as well facilitators to independent mobility such as electric wheelchairs are suggested to improve both experience and care outcomes. Interpersonal interactions demonstrated obesity stigma in the hospital setting, with participants expressing the desire for more appropriate communication. People living with obesity self-reflected in the inpatient setting, suggesting that staff should be trained to utilise the opportunity to provide weight loss advice.

CONCLUSIONS

The themes identified in this study provide insight into the lived experience of people with obesity in hospital. This understanding provides direction for the development of improved models of care for people living with obesity in this setting and beyond.

Treatment of tibial shaft nonunion with a retained nail in morbidly obese patients

PURPOSE

Morbid obesity is a rising worldwide health problem. Tibial shaft nonunion with retained intramedullary nail (IMN) in the morbidly obese is a challenging orthopaedic problem. Prolonged immobilization carries a significant risk of complications. This study aimed to investigate whether decortication and cancellous bone grafting with the application of a circular external fixator (CEF) over the preexisting IMN can achieve fracture union and avoid serious complications.

METHODS

We retrospectively reviewed 27 consecutive morbidly obese patients treated for tibial diaphysis aseptic nonunion after failed IMN. All cases were treated with osteoperiosteal decortication, cancellous bone grafting, and fixation with CEF over the IMN. Peri-operative multidisciplinary patient evaluation included internal medicine, cardiology, chest, vascular surgery, and anesthesia consultations. The union rate, bone results, functional results, and complications were recorded.

RESULTS

The mean age of the patients was 37.9 years. The mean BMI was 45.8. Sixteen cases (59.3%) were treated for hypertrophic nonunion, while 11 cases (40.7%) were treated for atrophic nonunion. Seven cases (25.9%) had open initial injury, 14 cases (51.9%) had associated comorbidities, and seven cases (25.9%) were smokers. Twenty-six cases united. The mean time to union was 5.2 months. Bone results and functional results were good to excellent in 96.3% of the cases. We recorded 25 complications in 21 patients. However, most of the complications were minor.

CONCLUSION

Decortication and cancellous bone grafting with the application of CEF over the preexisting nail is a safe and reliable treatment method for aseptic tibial shaft nonunion with retained IMN in morbidly obese patients.

Outcomes of Obese and Morbidly Obese Patients Undergoing Percutaneous Coronary Intervention

BACKGROUND

The risks of percutaneous coronary intervention (PCI) in obese and particularly morbidly obese patients remain uncertain.

METHODS

1082 consecutive patients were categorised as non-obese (NO, body mass index (BMI) <30kg/m², n=688), obese (O, BMI 30-40kg/m², n=354) or morbidly obese (MO, BMI ≥40kg/m², n=40). Demographic and procedural information was collated. Monte Carlo simulations modelled radiation dosimetric data.

RESULTS

Obese and morbidly obese patients were younger (p=0.016), more frequently female (p=0.036), more frequently diabetic (p<0.0001), with better renal function (p<0.0001), and prior PCI (p=0.01). There was no difference in major adverse cardiovascular or cerebrovascular events (MACCE) (NO=1.2%, O=0.8%, MO=2.5%, p=NS), acute kidney injury, bleeding, length of stay, 30-day readmission or 30-day mortality. Obese and morbidly obese patients received increased contrast (NO=180 [150-230]mL, O=190 [160-250]mL, MO=200 [165-225]mL, p=0.016), dose area product (NO=75.56 [50.61-113.69]Gycm², O=116.4 [76.11-157.82]Gycm², MO=125.62 [92.22-158.81]Gycm², p<0.0001), entrance air kerma (NO=1439.42 [977.0-2075.5]mGy, O=2111.63 [1492.0-3011.0]mGy, MO=2376.0 [1700.0-3234.42]mGy, p<0.0001), and peak skin dose (NO=1439.42 [977.0-2075.5], O=2111.63 [1492.0-3011.0], MO=2376.0 [1700.0-3234.42], p<0.0001). Effective radiation dose increased in obese patients (NO=20.9±14.9mSv, O=27.4±17.1mSv, MO=24.1±12.6mSv, p<0.0001 for NO vs O, p=0.449 for NO vs MO).

CONCLUSIONS

Percutaneous coronary intervention can be performed in obese and morbidly obese patients without elevated risk for most clinical outcomes. However, radiation increases above levels that could cause both transient and late effects. Strategies should be pursued to minimise radiation dose.

Trauma and BMI Mortality

PURPOSE OF REVIEW

Obesity has been recognized as an impactful comorbid condition. It has been demonstrated to be an independent risk factor for morbidity and mortality following trauma.

RECENT FINDINGS

Multiple studies and reviews have strongly suggested obesity to be associated with increased risk for post-injury morbidity and mortality. As obesity is associated with a pro-inflammatory state, it has been suggested to negatively affect the respiratory, cardiovascular, coagulation, and renal systems and the ability and manner in which an obese patient heals. As obesity continues to rise at alarming rates in the USA, this population of patients requires special consideration and continued research is underway to delineate relationships between obesity, trauma, and outcomes in an effort to improve overall care.

Demand for specialised training for the obese trauma patient: National ATLS expert group survey results

BACKGROUND

The growing incidence of obesity in Western populations continues to place new stressors on health systems. Obese trauma patients present particular challenges across the entirety of the patient care pathway, and are at risk of higher lengths of stay, morbidity, and mortality. This study sought to assess a national group of trauma experts' opinions and knowledge regarding the management of obese trauma.

METHODS

A questionnaire was circulated to a trauma training providers and national steering committee members at a UK national Advance Trauma Life Support meeting. Demographic, knowledge, and opinion data was collected and collated for analysis.

RESULTS

109 questionnaires were returned (73% response rate). Broad agreement was reached that obese trauma patients were more challenging to manage (96.2% agreement) and suffered worse outcomes (89.9%). Only 22.2% felt their hospitals possessed appropriate resources to facilitate management. Up to a third of respondents had personally witnesses errors in care due to patient obesity. 90% believed specialist training for obese trauma could improve care.

DISCUSSION

There is broad consensus amongst UK trauma providers that obese trauma patients are at risk of poorer outcomes and errors in care. Knowledge and preparedness of centres to manage these patients is variable. There was broad consensus that specialist training for the management of obese trauma patients may improve outcomes.
