Using a meta-ethnographic approach to explore the nature of facilitation and teaching approaches employed in interprofessional education.

BACKGROUND: Interprofessional facilitators and teachers are regarded as central to the effective delivery of interprofessional education (IPE). As the IPE literature continues to expand, most studies have focused on reporting learner outcomes, with little attention paid to IPE facilitation. However, a number of studies have recently emerged reporting on this phenomenon. AIM: To present a synthesis of qualitative evidence on the facilitation of IPE, using a meta-ethnographic approach. METHODS: Electronic databases and journals were searched for the past 10 years. Of the 2164 abstracts initially found, 94 full papers were reviewed and subsequently 12 papers were included. Teams of two reviewers independently completed each step in the review process. The quality of these papers was assessed using a modified critical appraisal checklist. RESULTS: Seven key concepts embedded in the included studies were synthesized into three main factors which provided an insight into the nature of IPE facilitation. Specifically, the synthesis found that IPE facilitation is influenced by "contextual characteristics"; "facilitator experiences"; and the "use of different facilitation strategies". CONCLUSIONS: IPE facilitation is a complex activity affected by contextual, experiential and pedagogical factors. Further research is needed to explore the effects of these factors on the delivery of IPE.

Non-therapeutic omission of medications in acutely ill patients.

AIMS AND OBJECTIVES: To examine documentation of medication administration in medical and surgical patients. STUDY OBJECTIVES: (1) Determine the point prevalence of non-therapeutic medication omissions; (2) identify documented reasons for non-therapeutic medication omissions; (3) examine the relationship between length of stay and medication omissions; and (4) explore the impact of outlier status (e.g. medical patients managed on surgical wards) on medication administration. BACKGROUND: Acutely ill patients are particularly sensitive to health care errors. We previously identified a 26% rate of non-therapeutic medication omissions in patients admitted unexpectedly to intensive care unit (ICU) from medical and surgical wards. DESIGN: A point prevalence survey of 162 medical and surgical patients across four sites in the South West of England. METHOD: Data collected included: all instances of, and reasons for, non-therapeutic medication omission. We also recorded whether the patient was an 'outlier' and examined nursing documentation where no reason for medication omission was given on the drug chart. RESULTS: The number of patients who missed at least one medication was high across all sites (n = 129/162; 79.6%, range 60-88%), with a total of 1077 doses omitted. Patients who were outliers (e.g. surgical patients on a medical ward) were more likely to miss medications (100% versus 74%, p < 0.001). The most common missed medications were analgesia and anti-inflammatory drugs (28%, 299/1077); 203 of these were due to patient refusal. CONCLUSIONS: The extent of medications omitted for non-therapeutic reasons in medical and surgical patients is of concern. None were recorded as an adverse drug event; however, the extent of omitted or refused medications suggests the need for a review of prescribing and drug administration processes. These findings have important implications for the role of ICU outreach and liaison services, for example, including medication management in the monitoring of patients pre/post-ICU admission and support/education provided for ward staff. RELEVANCE TO CLINICAL PRACTICE: Detailed analysis of medication records suggests a number of areas of medication administration that would benefit from review.

A prospective study comparing radiographer- and clinician-based localization for patients with metastatic spinal cord compression (MSCC) to assess the feasibility of a radiographer-led service.

OBJECTIVE: To investigate whether there was parity between treatment fields localized by radiographers and clinicians, by comparing geographical variations and hence determining the feasibility of a radiographer-led service. METHODS: 23 patients with metastatic spinal cord compression (MSCC) were prospectively sampled. Four radiographers not involved in the original planning performed localization on each patient. The 92 localizations that they determined were compared with the clinician-approved fields. Agreement was defined as ≤0.5 cm between field length, width and three isocentre co-ordinates. To be feasible, agreement was required in a minimum of 97% of the cases. The potential time saved with a radiographer-led approach was also recorded. RESULTS: Agreement between clinicians and radiographers was 97.8%. For all field parameters, the average differences were <0.3 cm and were significantly different from the 0.5-cm median (p < 0.0001) that would establish no agreement using Wilcoxon signed-rank test. The average (range) delay awaiting clinician approval was 54 min (4-141 min). CONCLUSION: Strong agreement between radiographer and clinician localizations was established. It was also highlighted that time could be saved in the patient's pathway by removing the need to wait for clinician approval. We believe this supports a radiographer-led service. ADVANCES IN KNOWLEDGE: This article is novel, as it is the first known comparison between clinicians and radiographers in the localization of MSCC radiotherapy. These data show the feasibility of introducing radiographer-led practice and a methodology that could be potentially transferred to investigate the localization parity for other treatment sites.

An assessment of the magnitude of intra-fraction movement of head-and-neck IMRT cases and its implication on the action-level of the imaging protocol.

BACKGROUND AND PURPOSE: A planning margin ⩽3 mm is employed in some head-and-neck IMRT cases due to the proximity of critical structures. This study aims to explore the need to redefine the action-level in the head-and-neck imaging protocol in consideration of the intra-fraction movement. MATERIAL AND METHODS: This is a local study of 18 patients treated using the same immobilisation system and setup protocol. Post-treatment orthogonal pair of kilovoltage X-ray images was acquired on the first three days of treatment. 106 sets of pre- and post-treatment kV X-ray images acquired over 53 fractions were analysed against the treatment planning DRR for calculation of intra-fraction movement. RESULTS: Individual mean intra-fraction movement in all directions ranged from -1.8 to 1.1 mm. Population mean (median) intra-fraction movement in the x-, y-, and z-planes were -0.1 mm (0 mm), -0.3 mm (-0.3 mm) and -0.2 mm (-0.2 mm) respectively. Intra-fraction movement in all three dimensions, x-, y- and z-planes were considered statistically significant (p<0.05). 7 out of 53 fractions (13.2%) were highlighted as the combined magnitude of the intra-fraction motion with the uncorrected pre-treatment setup errors had exceeded the boundaries of given margins. CONCLUSIONS: 3 mm-AL was not adequate to account for intra-fraction movement when the CTV-PTV margin was ⩽3 mm and should be excluded from the routine imaging protocol and daily image-guided radiotherapy should be employed. Adjusting the action-level to 2 mm would allow a more confident approach in delivery of the prescribed dose in head-and-neck IMRT cases.

Acute tryptophan depletion alters gastrointestinal and anxiety symptoms in irritable bowel syndrome.

OBJECTIVES: To assess the effect of acute changes in serotonin (5-HT) synthesis using the acute tryptophan depletion (ATD) paradigm on gastrointestinal (GI) and mood symptoms in irritable bowel syndrome (IBS). METHODS: In a randomized double-blind crossover study, 29 subjects (18 patients with ROME II defined IBS and 11 age-matched controls) were studied under ATD and acute tryptophan increase (ATI) conditions. GI symptoms, mood and anxiety ratings, as well as plasma tryptophan concentrations were measured. RESULTS: Total (and free) plasma tryptophan concentrations decreased on the ATD day in patients (73%[82%]) and controls (73%[80%]), and increased on the ATI day in patients (59%[143%]) and controls (61%[381%]). Compared with the ATD day, IBS patients reported more GI symptoms on the ATI day at +210 (p < 0.001) and at +270 (p < 0.05) min post drink. IBS patients also reported less anxiety on the ATI day compared with the ATD day at +270 min (p < 0.001). ATD and ATI did not affect these ratings in control participants. IBS patients had a lower mood compared with controls (p < 0.05), but this did not differ between the ATI and ATD days in either group. CONCLUSIONS: IBS patients' GI and anxiety responses to changes in tryptophan load differ from controls. This suggests a difference in serotonergic functioning between these two groups and provides evidence to support the hypothesis that 5-HT dysfunction is involved in IBS.
