Complex Decision Makin g in Providing Surgical Intensive Care
Decisions made by physicians in intensive care medicine
are often complex, requiring the consideration of
information that may be incomplete, ambiguous, or even
contradictory. Under conditions of complexity and
uncertainty, individuals may cope by using simplifying
decision strategies. The research described in this paper
examines the strategies used by physicians in coping with
complexity in decision making. Six residents
(intermediates) and three specialists in intensive care were
each presented with 12 cases of intensive care respiratory
problems of varying levels of complexity. The subjects
were asked to think-aloud as they worked through the
problems and provided a management and treatment plan
for each case. The audiotaped protocols were coded for
key process variables in decision making and problem
solving. Despite the incompleteness and ambiguity of the
information available, the confidence of physicians in
their decision making was consistently high. The
strategies used by intermediates and experts in dealing
with the more complex cases varied considerably. Expert
physicians were found to focus on the assessment of the
decision problems to a greater extent than intermediates.
Implications for research in decision making and medical
cognition are discussed
Exploring factors that influence the spread and sustainability of a dysphagia innovation: an instrumental case study
Background: Swallowing difficulties challenge patient safety due to the increased risk of malnutrition, dehydration
and aspiration pneumonia. A theoretically driven study was undertaken to examine the spread and sustainability of
a locally developed innovation that involved using the Inter-Professional Dysphagia Framework to structure
education for the workforce. A conceptual framework with 3 spread strategies (hierarchical control, participatory
adaptation and facilitated evolution) was blended with a processual approach to sustaining organisational change.
The aim was to understand the processes, mechanism and outcomes associated with the spread and sustainability
of this safety initiative.
Methods: An instrumental case study, prospectively tracked a dysphagia innovation for 34 months (April 2011
to January 2014) in a large health care organisation in England. A train-the-trainer intervention (as participatory
adaptation) was deployed on care pathways for stroke and fractured neck of femur. Data were collected at the
organisational and clinical level through interviews (n = 30) and document review. The coding frame combined
the processual approach with the spread mechanisms. Pre-determined outcomes included the number of staff
trained about dysphagia and impact related to changes in practice.
Results: The features and processes associated with hierarchical control and participatory adaptation were
identified. Leadership, critical junctures, temporality and making the innovation routine were aspects of hierarchical
control. Participatory adaptation was evident on the care pathways through stakeholder responses, workload and
resource pressures. Six of the 25 ward based trainers cascaded the dysphagia training. The expected outcomes
were achieved when the top-down mandate (hierarchical control) was supplemented by local engagement and
support (participatory adaptation).
Conclusions: Frameworks for spread and sustainability were combined to create a ‘small theory’ that described
the interventions, the processes and desired outcomes a priori. This novel methodological approach confirmed
what is known about spread and sustainability, highlighted the particularity of change and offered new insights
into the factors associated with hierarchical control and participatory adaptation. The findings illustrate the dualities
of organisational change as universal and context specific; as particular and amendable to theoretical generalisation.
Appreciating these dualities may contribute to understanding why many innovations fail to become routine
Aquatic therapy for children with Duchenne muscular dystrophy: a pilot feasibility randomised controlled trial and mixed-methods process evaluation.
BACKGROUND: Duchenne muscular dystrophy (DMD) is a rare disease that causes the progressive loss of motor abilities such as walking. Standard treatment includes physiotherapy. No trial has evaluated whether or not adding aquatic therapy (AT) to land-based therapy (LBT) exercises helps to keep muscles strong and children independent.
OBJECTIVES: To assess the feasibility of recruiting boys with DMD to a randomised trial evaluating AT (primary objective) and to collect data from them; to assess how, and how well, the intervention and trial procedures work.
DESIGN: Parallel-group, single-blind, randomised pilot trial with nested qualitative research.
SETTING: Six paediatric neuromuscular units.
PARTICIPANTS: Children with DMD aged 7-16 years, established on corticosteroids, with a North Star Ambulatory Assessment (NSAA) score of 8-34 and able to complete a 10-m walk without aids/assistance. Exclusions: > 20% variation between baseline screens 4 weeks apart and contraindications.
INTERVENTIONS: Participants were allocated on a 1 : 1 ratio to (1) optimised, manualised LBT (prescribed by specialist neuromuscular physiotherapists) or (2) the same plus manualised AT (30 minutes, twice weekly for 6 months: active assisted and/or passive stretching regime; simulated or real functional activities; submaximal exercise). Semistructured interviews with participants, parents (n = 8) and professionals (n = 8) were analysed using Framework analysis. An independent rater reviewed patient records to determine the extent to which treatment was optimised. A cost-impact analysis was performed. Quantitative and qualitative data were mixed using a triangulation exercise.
MAIN OUTCOME MEASURES: Feasibility of recruiting 40 participants in 6 months, participant and therapist views on the acceptability of the intervention and research protocols, clinical outcomes including NSAA, independent assessment of treatment optimisation and intervention costs.
RESULTS: Over 6 months, 348 children were screened - most lived too far from centres or were enrolled in other trials. Twelve (30% of target) were randomised to AT (n = 8) or control (n = 4). People in the AT (n = 8) and control (n = 2: attrition because of parental report) arms contributed outcome data. The mean change in NSAA score at 6 months was -5.5 [standard deviation (SD) 7.8] for LBT and -2.8 (SD 4.1) in the AT arm. One boy suffered pain and fatigue after AT, which resolved the same day. Physiotherapists and parents valued AT and believed that it should be delivered in community settings. The independent rater considered AT optimised for three out of eight children, with other children given programmes that were too extensive and insufficiently focused. The estimated NHS costs of 6-month service were between £1970 and £2734 per patient.
LIMITATIONS: The focus on delivery in hospitals limits generalisability.
CONCLUSIONS: Neither a full-scale frequentist randomised controlled trial (RCT) recruiting in the UK alone nor a twice-weekly open-ended AT course delivered at tertiary centres is feasible. Further intervention development research is needed to identify how community-based pools can be accessed, and how families can link with each other and community physiotherapists to access tailored AT programmes guided by highly specialised physiotherapists. Bayesian RCTs may be feasible; otherwise, time series designs are recommended.

Teaching tools in Evidence Based Practice: evaluation of reusable learning objects (RLOs) for learning about Meta-analysis
<p>Abstract</p> <p>Background</p> <p>All healthcare students are taught the principles of evidence based practice on their courses. The ability to understand the procedures used in systematically reviewing evidence reported in studies, such as meta-analysis, are an important element of evidence based practice. Meta-analysis is a difficult statistical concept for healthcare students to understand yet it is an important technique used in systematic reviews to pool data from studies to look at combined effectiveness of treatments. In other areas of the healthcare curricula, by supplementing lectures, workbooks and workshops with pedagogically designed, multimedia learning objects (known as reusable learning objects or RLOs) we have shown an improvement in students' perceived understanding in subjects they found difficult. In this study we describe the development and evaluation of two RLOs on meta-analysis. The RLOs supplement associated lectures and aim to improve students' understanding of meta-analysis in healthcare students.</p> <p>Methods</p> <p>Following a quality controlled design process two RLOs were developed and delivered to two cohorts of students, a Master in Public Health course and Postgraduate diploma in nursing course. Students' understanding of five key concepts of Meta-analysis were measured before and after a lecture and again after RLO use. RLOs were also evaluated for their educational value, learning support, media attributes and usability using closed and open questions.</p> <p>Results</p> <p>Students rated their understanding of meta-analysis as improved after a lecture and further improved after completing the RLOs (Wilcoxon paired test, p < 0.01 in all cases) Whilst the media components of the RLOs such as animations helped most students (86%) understand concepts including for example Forest plots, 93% of students rated usability and control as important to their learning. A small number of students stated they needed the support of a lecturer alongside the RLOs (7% 'Agreed' and 21% 'Neutral').</p> <p>Conclusions</p> <p>Meta-analysis RLOs that are openly accessible and unrestricted by usernames and passwords provide flexible support for students who find the process of meta-analysis difficult.</p

Pharmacology education for nurse prescribing students – a lesson in reusable learning objects
<p>Abstract</p> <p>Background</p> <p>The shift away from a biological science to a social science model of nursing care has resulted in a reduction in pharmacology knowledge and understanding in pre-registration nursing students. This has a significant impact on nurse prescribing training where pharmacology is a critical component of the course from a patient safety perspective.</p> <p>Methods</p> <p>Reusable learning objects (RLOs) are electronic resources based on a single learning objective which use high quality graphics and audio to help engagement with the material and to facilitate learning. This study used questionnaire data from three successive cohorts of nurse prescribing students (n = 84) to evaluate the use of RLOs focussed around pharmacology concepts to promote the understanding of these concepts in students. A small number of students (n = 10) were followed up by telephone interview one year after qualification to gain further insight into students' perceptions of the value of RLOs as an educational tool.</p> <p>Results</p> <p>Students' perceptions of their own understanding of pharmacology concepts increased substantially following the introduction of RLOs to supplement the pharmacology component of the course. Student evaluation of the RLOs themselves was extremely positive with a number of students continuing to access these tools post-qualification.</p> <p>Conclusion</p> <p>The use of RLOs to support the pharmacology component of nurse prescribing courses successfully resulted in a perceived increase in pharmacology understanding, with some students directly implicating these educational tools in developing confidence in their own prescribing abilities.</p
Universal Genetic Testing for Newly Diagnosed Invasive Breast Cancer
IMPORTANCE Between 5% and 10% of breast cancer cases are associated with an inherited germline pathogenic or likely pathogenic variant (GPV) in a breast cancer susceptibility gene (BCSG), which could alter local and systemic therapy recommendations. Traditional genetic testing criteria misses a proportion of these cases. OBJECTIVE To evaluate the prevalence and clinicopathological associations of GPVs in 2 groups of BCSGs among an ethnically diverse cohort of women with newly diagnosed breast cancer. DESIGN, SETTING, AND PARTICIPANTS This cross-sectional study, conducted at 3 Montreal hospitals between September 2019 and April 2022, offered universal genetic counseling and testing to all women with a first diagnosis of invasive breast cancer. Women were offered an obligatory primary panel of BRCA1, BRCA2, and PALB2 (B1B2P2) and an optional secondary panel of 14 additional BCSGs. Eligible participants were women 18 years of age or older who received a diagnosis of a first primary invasive breast cancer not more than 6 months before the time of referral to the study. Data were analyzed from November 2023 to June 2024. RESULTS Of 1017 referred patients, 805 were eligible and offered genetic counseling and testing, and 729 of those 805 (90.6%) consented to be tested. The median age at breast cancer diagnosis was 53 years (range, 23-91 years), and 65.4% were White and of European ancestry. Fifty-four GPVs were identified in 53 patients (7.3%), including 39 patients (5.3%) with B1B2P2 and 15 patients (2.1%) with 6 of the 14 secondary panel BCSGs (ATM, BARD1, BRIP1, CHEK2, RAD51D, and STK11). On multivariable analysis, clinical factors independently associated with B1B2P2-positive status included being younger than 40 years of age at diagnosis (odds ratio [OR], 6.83; 95% CI, 2.22-20.90), triple-negative breast cancer (OR, 3.19; 95% CI, 1.20-8.43), high grade disease (OR, 1.68; 95% CI, 1.05-2.70), and family history of ovarian cancer (OR, 9.75; 95% CI, 2.65-35.85). Of 39 B1B2P2-positive patients, 13 (33.3%) were eligible for poly(adenosine diphosphate-ribose) polymerase (PARP) inhibitors. CONCLUSIONS AND RELEVANCE In this cross-sectional universal genetic testing study of women with newly diagnosed invasive breast cancer, the prevalence of GPVs was 7.3%, with 5.3% of patients testing positive for B1B2P2. Among B1B2P2-women women, one-third were eligible for PARP inhibitors.Scopu
