Plain abdominal radiographs to diagnose constipation patients with advanced progressive illness?

Understanding experiences of the radiography workforce delivering medical imaging as part of patients' end of life care: An exploratory qualitative interview study

INTRODUCTION

People nearing the end of life often require medical imaging in hospitals to manage symptoms and care, despite this little is known about the experiences of those delivering it. The aim of this study is therefore to explore the experiences of the radiography workforce delivering medical imaging as part of patients' end-of-life care.

METHOD

Qualitative design using semi-structured interviews and thematic analysis. A total of 8 participants participated in the study including registered diagnostic radiographers (n = 5), imaging assistants (n = 2) and assistant practitioners (n = 1). All have been involved in the medical imaging of patients receiving end of life care in UK hospitals.

RESULTS

Findings identified an absence of end of life care policy guidance and education accessible to radiography staff, limiting their ability to provide evidenced based care for those nearing the end of life during medical imaging examinations. Findings also suggest difficulty in identifying patients receiving end of life care further hindered staffs' ability to adapt their care to provide a more person-centred approach. Lastly, the workforce felt an accumulative emotional burden following their interactions with patients nearing the end of life.

CONCLUSION

There is a clear need to develop policy and education to support the radiography workforce to ensure care is appropriately identified and adapted to those nearing the end of life. Furthermore, staff support and wellbeing needs to be considered.

IMPLICATIONS FOR PRACTICE

Future research is required exploring the patient perspective to understand their experiences so that the education and practice provision is driven by patient need. International exploration of end of life care in medical imaging is recommended to explore whether similar challenges related to clinical practice exist in other countries.

Colonic stool burden on computed tomography does not correlate with bowel habit: a cross-sectional study

PURPOSE

Stool burden on abdominal radiographs is not reflective of constipation, perhaps because of variable fecal shadowing or limited inter-rater agreement. These limitations are hypothetically mitigated by computed tomography (CT). This research aimed (i) to evaluate whether bowel movement frequency, stool form, or a diagnosis of functional constipation correlate or associate with stool burden identified on CT, and (ii) to investigate whether physicians use CT in their assessment of a patients' bowel function.

METHODS

Patients attending for non-emergent abdominal CT imaging were invited to participate by completing a bowel questionnaire. Stool burden identified on imaging was determined and inter-rater reliability was evaluated in a subgroup of patients (n = 20). Descriptive and comparative analyses were performed. An online questionnaire evaluated the use of abdominal imaging in assessing patients' bowel function in a cross-section of ordering physicians.

RESULTS

The patient response rate was 19% (96/516). No clinically useful associations between fecal burden and stool form, bowel motion frequency, gastrointestinal symptoms or a diagnosis of constipation was identified. The physician response rate was 35% (33/94). Opportunistic use of data was more common than deliberate use. However, an abdominal radiograph or CT scan had been requested by 42% and 18% of physicians respectively to assess patient's chronic bowel habit. Approximately 30% of physicians believed evidence supported this practice.

CONCLUSIONS

Physicians may use abdominal CT in their assessment of patients' chronic bowel habits. However, objective assessment does not support this practice. Colonic stool burden does not correlate with patient-reported symptoms or a criteria-based diagnosis of constipation.

Examining Clinical Utility of Imaging for Inpatient Palliative Care

BACKGROUND

Medicine in the final months of life is increasingly interventional, both in the manner by which life may be prolonged and symptoms may be reduced. Radiology is frequently utilized to provide diagnostic clarity and improve symptom control. As with any intervention, examining the benefit and potential harms of a procedure is required to establish its role in ongoing clinical care.

METHODS

This retrospective cohort study involved patients admitted to an inpatient palliative care unit between October 2013 and September 2014. Data were collected using clinical databases manually searched by the researchers.

RESULTS

Of 388 admissions, there were a total of 154 imaging events completed in 85 patients. Patients who had imaging performed had longer mean length of stays, more likely to be discharged home, and male. Very few imaging events (4%) occurred in the 3 days prior to death and none on the day of death. In total, 43% of imaging confirmed the clinical suspicion and management changed 42% of times. Limbs X-rays and computed tomography brain had low rates of confirming clinical suspicion (21% and 17%) and changing management (21% and 33%). There were a total of 7 complications resulting from imaging, the majority due to interventional procedures.

CONCLUSION

The use of imaging in inpatient palliative care seems to be of substantive utility, prompting alterations in management in >40% of instances. The majority of imaging occurred prior to the terminal phase of the disease and with few complications.

The disparity between patient and nurse symptom rating in a hospice population

BACKGROUND

Meticulous assessment, monitoring, and treatment of symptoms are key components of palliative care. The Symptom Assessment Scale (SAS) is a 0-10 numerical rating scale (NRS) used for self-report of sleep, appetite, nausea, bowels, breathing, fatigue, and pain. Ideally, symptom rating should be by self-report; however, the ratings are often completed by nurses. The aim of this study was to examine the relationship between simultaneous symptom ratings of patients and nurses in an Australian inpatient palliative care unit.

METHODS

All inpatients and their treating nurse (blinded to the patient's report) scored the SAS weekly. Nurse symptom rating was considered accurate if the score for an individual symptom differed by ≤1. The relationship for each dyad was examined by comparing absolute values, mean differences, and Pearson correlations.

RESULTS

Sixty-four pairs of symptom ratings were obtained from 29 patients (mean 65 years, male 55%, malignancy 90%, mean Karnofsky 50). The absolute differences were closest for nausea, bowels, and breathing domains, and worst for appetite. Mean differences and Pearson correlations did not adequately reflect the disparity between patient and nurse symptom rating, and nurses systematically underreported symptoms. The total difference for the seven items ranged from nurses overreporting the patients' symptoms by 39 points to underreporting by 31 out of a possible 70 points.

DISCUSSION

Proxy symptom assessment only modestly correlates with patient symptom rating, can significantly misrepresent the patient's actual symptom burden, and should only be used when the patient is absolutely unable to contribute his or her own view.
