In this article, we set out the current context and case for change in radiology in England and how quality-improvement approaches can support the development of sustainable Imaging services and networks to meet the challenges faced now and in the future.

Explaining the adoption and use of computed tomography and magnetic resonance image technologies in public hospitals

Objective

This article examines what the adoption and use of advanced medical technologies – computed tomography (CT) and magnetic resonance imaging (MRI) – by public hospitals depend on and to what extent.

Methods

From a sample of panel data for all public hospitals in the health service of Galicia (a subregion of the Galicia-North of Portugal Euroregion) for the 2010–2017 period, we grouped explanatory variables into inputs (resources), outputs (activities) and socio-demographic variables. Factor analysis was used to reduce as much as possible the number of analysed variables, discriminant analysis to examine the technologies adoption decision, and multiple regression analysis to investigate their use.

Results

Factor analysis identified motivators on adoption and use of CT and MRI medical technologies as follows: hospital inputs/outputs (Factor 1); radiology studies and adoption of CT by public hospitals (Factor 2); research/teaching role and big-ticket diagnostic and therapeutic (lithotripsy) technologies (Factor 3); number of transplants (Factor 4); cancer diagnosis/treatment (Factor 5); and catchment area geographical dispersion (Factor 6). Cronbach’s alpha of 0.881 indicated an acceptable degree of reliability of the factor variables. Regarding adoption of these technologies, Factor 1 is the most influential, explaining 37% of the variance and showing adequate global internal consistency, whereas Factor 2 is limited to 13% of the variance. In the discriminant analysis, values for Box’s M test and canonical correlations such as Wilks’s lambda for the two technologies underpin the reliability and predictive capacity of the discriminant equations. Finally, and according to the regression analysis, the factor with the greatest influence on CT and MRI use is Factor 2, followed by Factors 1 and 3 in the case of CT use, and Factors 3 and 5 in the case of MRI use.

Conclusion

CT and MRI adoption by public hospitals is mainly determined by hospital inputs and outputs. However, the use of both medical technologies is mainly influenced by conventional radiology studies and CT adoption. These results suggest that both choices – adoption and use of advanced medical technology – may be separate decisions as they are taken possibly by different people (the former by managers and policymakers and the latter by physicians).

The effect of length, duration, and intensity of psychological therapy on CORE global distress scores

OBJECTIVES

This study explores whether improvements, as measured by the CORE-OM/10, as a result of psychological therapy were related to length of treatment in weeks, number of treatment sessions, or treatment intensity, as well as any effect of diagnostic group.

METHODS AND DESIGN

Pre- and post-therapy CORE-OM/10 scores were extracted from the clinical records of all secondary care adult psychological therapy team patients who undertook psychological therapy between 2010 and 2013 in one mental health trust. Of the 4,877 patients identified, 925 had complete records. Length of therapy was divided by the number of sessions to create 'treatment intensity' (sessions per week). Nonparametric analyses were used, initial score was controlled for, and diagnostic group was explored.

RESULTS

No relationship was found between change in score and the number of sessions, therapy length, or treatment intensity; however, change in score was positively correlated with first-session score. Patients with higher initial scores had longer therapies; however, treatment intensity was similar for patients with lower pre-therapy distress. There were differences in treatment length (weeks) between diagnostic groups. Demographic differences were found between patients with and without complete records, prompting caution in terms of generalizability.

CONCLUSIONS

These findings are consistent with the responsive regulation model (Barkham et al., 1996) which proposes that patients vary in their response to treatment, resulting in no associations between session numbers or treatment intensity and therapeutic gain with aggregated scores. Patients with higher CORE scores at the outset of psychological therapy had longer not more intensive therapy. There was variation in treatment intensity between diagnostic clusters.

PRACTITIONER POINTS

Number of sessions, length of therapy (in weeks), and treatment intensity (the number of sessions per week between the first and last therapy sessions) were not related to therapeutic gains. These results fit with a responsive regulation model of therapy duration, suggesting an individualized approach to therapy cessation as opposed to therapy session limits as the number of sessions a patient experienced was not generally associated with outcome. We found that clients with a diagnosis of a behavioural syndrome (F50-59) had less 'intensive' therapy; they experienced the same number of sessions over a longer time frame. Despite this, there were no associations between diagnosis category and change in score.

Clinical outcome following primary total hip or knee replacement in nonagenarians

Introduction The Elective Orthopaedic Centre in Epsom has an established patient reported outcome measures programme, into which all patients are enrolled. Postoperative complications, Oxford hip/knee scores (OHS/OKS) and EQ-5D™ (EuroQol, Rotterdam, Netherlands) scores are collected up to the second postoperative year. Our population is ageing and the number of joint replacements being performed on the very elderly is rising. The aim of this study was to investigate the outcome of joint replacements in a nonagenarian population. Methods Our dataset was reviewed retrospectively for a cohort of nonagenarians undergoing either a primary total hip replacement (THR) or total knee replacement (TKR) between April 2008 and October 2011. Postoperative complications, mortality rates and functional outcomes were compared with those of a time matched 70-79-year-old cohort. Results Nonagenarians requiring a THR presented with a lower preoperative OHS (p=0.020) but made a greater improvement in the first postoperative year than the younger cohort (p=0.040). The preoperative OKS was lower for nonagenarians than for the control group (p=0.022). At one and two years after TKR, however, there was no significant difference between the age groups. The nonagenarians had a greater risk of requiring a blood transfusion following both THR (p=0.027; 95% confidence interval [CI]: 1.11-5.75) and TKR (p=0.037; 95% CI: 1.08-16.65) while the latter cohort also required a longer stay than their younger counterparts (p=0.001). Mortality rates were higher in the nonagenarian group but these were in keeping with the life expectancy projections identified by the Office for National Statistics. Conclusions Over a two-year period, the functional outcome and satisfaction rates achieved by nonagenarians following a THR or TKR are comparable with 70-79-year-olds.

Surgical referral criteria for degenerative rotator cuff tears: a Delphi questionnaire study

Selecting the most appropriate patients to refer for surgery is crucial for high-quality and efficient clinical care. However, there are no specific referral criteria to guide the referral of appropriate patients for rotator cuff repair surgery. The aim of the present study was to design robust surgical referral criteria for patients with degenerative rotator cuff tears using consensus methodology. A two-round Delphi questionnaire was undertaken with a nationally representative sample of 41 specialist shoulder surgeons experienced in rotator cuff repair. Surgical referral criteria for degenerative rotator cuff tear were developed where consensus of at least 70% agreement was achieved. The initial questionnaire consisted of 24 items. Consensus was reached on 14 items, including: severity of pain, functional limitation, the identification of fat atrophy, agreement that a course of physiotherapy should be attempted before surgical referral, and exclusion for those with an active frozen shoulder. However, there was no consensus with regard to the dimensions of the tear. The surgical referral criteria developed were novel and promising for patients with degenerative rotator cuff tears, and further research is required to examine their efficacy.
