Prostatic pathology reporting in the UK: development of a national external quality assurance scheme

Aims:  To develop a baseline picture of prostatic pathology reporting in the UK, identify areas of particular difficulty and assess the feasibility of a national external quality assurance scheme based on prostatic biopsy specimens using the same format as the National Health Service breast pathology scheme, as recommended by the National Institute for Clinical Excellence.
Methods and results:  Eight expert uropathologists and 32 randomly selected pathologists participated in four circulations each of 12 cases of prostatic biopsy specimens. A fixed text proforma was developed and responses were analysed for interobserver agreement using κ statistics. Consistency of reporting the main diagnostic categories of benign and invasive carcinoma was good (κ values 0.77 and 0.88, respectively), but only after excluding 19% of cases for which the experts did not reach 75% agreement. Areas of difficulty included the diagnosis of high-grade prostatic intraepithelial neoplasia and small foci of cancer. Prognostic factor reporting was more variable, with lower overall κs for the assessment of Gleason grading (experts 0.55, others 0.50), perineural invasion (experts 0.64, others 0.50) and number of positive cores (experts 0.74, others 0.61).
Conclusions:  Given the difficulties in diagnosis of prostatic biopsy specimens and the assessment of prognostic factors, the expansion of the scheme could deliver important educational benefits.     

An update on head and neck cancer: new entities and their histopathology,molecular background,treatment, and outcome

The head and neck region harbor numerous specialized tissues of all lineages giving rise to a plethora of different malignancies. In recent years, new types and subtypes of cancer has been described here due to the recognition of their histological and molecular characteristics. Some have been formally accepted in the most recent classifications from the World Health Organization (WHO) and American Joint Committee on Cancer (AJCC) as distinct diseases due to characteristics in clinical presentation, outcome, and treatment. In particular, this applies to malignancies of the salivary gland, sinonasal tract, and oropharynx. In this overview, we present the most recent developments in the classification, histopathological characteristics, and molecular features of head and neck cancer. The clinical and radiological characteristics, outcome, and treatment options including perspectives for targeted therapies, are discussed.     

Patient experience and the role of postgraduate GP training: a cross-sectional analysis of national Patient Survey data in England

Background

Quality indicators for primary care focus predominantly on the public health model and organisational measures. Patient experience is an important dimension of quality. Accreditation for GP training practices requires demonstration of a series of attributes including patient-centred care.

Aim

The national GP Patient Survey (GPPS) was used to determine the characteristics of general practices scoring highly in responses relating to the professional skills and characteristics of doctors. Specifically, to determine whether active participation in postgraduate GP training was associated with more positive experiences of care.

Design and setting

Retrospective cross-sectional study in general practices in England.

Method

Data were obtained from the national QOF dataset for England, 2011/12 (8164 general practices); the GPPS in 2012 (2.7 million questionnaires in England; response rate 36%); general practice and demographic characteristics. Sensitivity analyses included local data validated by practice inspections. Outcome measures: multilevel regression models adjusted for clustering.

Results

GP training practice status (29% of practices) was a significant predictor of positive GPPS responses to all questions in the ‘doctor care’ (n = 6) and ‘overall satisfaction’ (n = 2) domains but not to any of the ‘nurse care’ or ‘out-of-hours’ domain questions. The findings were supported by the sensitivity analyses. Other positive determinants were: smaller practice and individual GP list sizes, more older patients, lower social deprivation and fewer ethnic minority patients.

Conclusion

Based on GPPS responses, doctors in GP training practices appeared to offer more patient-centred care with patients reporting more positively on attributes of doctors such as ‘listening’ or ‘care and concern’.     

Primary lower limb lymphedema: a focus on its functional, social and emotional impact

Primary lymphedema is a rare, chronic and distressing condition with negative effects on physical, social and emotional level. The purpose of these reports was to present and discuss two different cases of primary lower limb lymphedema with a focus on its physical and mental impact and on some qualitative aspects of patients' self-reported experiences. The patients were recruited as they used occasional services within the University Hospital of Heraklion (Crete, Greece). The functional and mental impact of primary lymphedema was measured using the generic Medical Outcome Study short form-36 questionnaire and open-ended questions led to give more emphasis to patients' experiences. The analysis of short form-36 results in the first patient disclosed a significant functional impairment with a minor impact of the condition on emotional and social domains. For the second patient quality of life scores in the emotional and social domains were affected. Our findings support further the statement that physicians should pay full attention to appraise the patient's physical and emotional condition. General practitioners have the opportunity to monitor the long-term impact of chronic disorders. Posing simple open-ended questions and assessing the level of physical and mental deficits in terms of well-being through the use of specific metric tools can effectively follow-up rare conditions in the community.     

Assessing depression severity using the UK Quality and Outcomes Framework depression indicators: a systematic review

BackgroundDepression is a major cause of chronic ill-health and is managed in primary care. Indicators on depression severity assessment were introduced into the UK Quality and Outcomes Framework (QOF) in 2006 and 2009. QOF is a pay-for-performance scheme and indicators should have evidence to support their use; potential unintended consequences should also have been considered.AimTo review the effectiveness of routine assessment of depression severity using structured tools in primary care, and to determine the views of GPs and patients regarding their use.DesignSystematic review.MethodStudies were identified by searching electronic databases; study selection, data abstraction, and quality assessment were carried out by one reviewer, with checks from other authors and GRADE (grading of recommendations, assessment, development and evaluation) tables completed for included effectiveness studies.ResultsEight studies met the eligibility criteria. There was very low-quality evidence that assessing severity in a structured way at diagnosis using a validated tool led to interventions that were appropriate to the severity of depression. Patients and GPs had different perceptions of the assessment of depression at diagnosis, with patients being more positive. GPs highlighted unintended consequences. There was low-quality evidence that structured assessment at follow-up led to increased rates of remission and response, but changes to management were not seen. Patients used this assessment to measure their own response to treatment.ConclusionAny estimate of the effect of structured assessment of depression severity in UK general practice is uncertain. GPs consider routine use of questionnaires as incentivised by the QOF has unintended consequences, which could adversely affect patient care.     

Type and accuracy of sphygmomanometers in primary care: a cross-sectional observational study

Background

Previous studies identified worrying levels of sphygmomanometer inaccuracy and have not been repeated in the era of digital measurement of blood pressure

Aim

To establish the type and accuracy of sphygmomanometers in current use

Design and setting

Cross-sectional, observational study in 38 Oxfordshire primary care practices

Method

Sphygmomanometers were evaluated between 50 and 250 mmHg, using Omron PA350 or Scandmed 950831-2 pressure meters.

Results

Six hundred and four sphygmomanometers were identified: 323 digital (53%), 192 aneroid (32%), 79 mercury (13%), and 10 hybrid (2%) devices. Of these, 584 (97%) could be fully tested. Overall, 503/584 (86%) were within 3 mmHg of the reference, 77/584 (13%) had one or more errorof 4-9 mmHg, and 4/584 (<1%) had one or more errorof more than 10 mmHg. Mercury (71/75, 95%) and digital (272/308, 88%) devices were more likely to be within 3 mmHg of the reference standard than aneroid models (150/191, 78%) (Fisher''s exact test P = 0.001). Donated aneroid devices from the pharmaceutical industry performed significantly worse: 10/23 (43%) within 3 mmHg of standard compared to 140/168 (83%) aneroid models from recognised manufacturers (Fisher''s exact test P<0.001). No significant difference was found in performance between manufacturers within each device type, for either aneroid (Fisher''s exact test P = 0.96) or digital (Fisher''s exact test P = 0.7) devices.

Conclusion

Digital sphygmomanometers have largely replaced mercury models in primary care and have equivalent accuracy. Aneroid devices have higherfailure rates than other device types; this appears to be largely accounted forby models from indiscernible manufacturers. Given the availability of inexpensive and accurate digital models, GPs could consider replacing aneroid devices with digital equivalents, especially for home visiting.     

New observations on the etiology of aortic valve disease: A surgical pathologic study of 236 cases from 1990

Among 236 aortic valves surgically excised at the Mayo Clinic in 1990 (mean patient age, 66 years; age range, 10 to 92 years), 154 (65%) were stenotic, 58 (25%) were insufficient, and 24 (10%) were both stenotic and insufficient. Pure stenosis was related to calcification, and causes included degenerative (51%), bicuspid (36%), postinflammatory (9%), and other (4%) reasons. Fourteen (9%) valves with pure stenosis also underwent ventricular septal myectomy, 12 for hypertrophy and two for co-existent hypertrophic cardiomyopathy. Pure insufficiency was not related to calcification, and causes included aortic root dilatation (50%), bicuspid valve (14%), postinflammatory (14%), posttherapeutic (14%), and other (8%) reasons. Combined stenosis and insufficiency was secondary to degenerative calcification (46%), bicuspid and postinflammatory etiologies (17% each), posttherapeutic (13%), and indeterminate (8%) causes. New observations include the following findings: (1) degenerative (senile) disease is the most common cause of aortic stenosis and combined stenosis and insufficiency at the Mayo Clinic, (2) aortic root dilatation is the most common cause of pure aortic insufficiency, (3) posttherapeutic aortic valve disease now leads to valve replacement in a substantial percentage of patients, particularly among those with insufficiency, (4) postinflammatory (presumably rheumatic) disease is relatively uncommon in all three functional categories, (5) septal myectomy may be performed for hypertrophic states other than hypertrophic cardiomyopathy, and (6) adults with operated congenital heart disease are undergoing valve replacement for annular dilatation with insufficiency. Because of the increasing age of the general population, the prominence of age-related degenerative aortic valve calcification and aortic root dilatation may have important implications concerning future health care costs.     

Molecular biology in diagnostic histopathology. Part 3: signal transduction

Signal transduction pathways allow cellular behaviour to be modulated in response to extracellular stimuli. The molecular components of these pathways make attractive targets for pharmacological intervention, and progressive advances in our understanding of specific signal transduction pathways is facilitating the development of a large number of novel signal transduction inhibitors. Rational therapy is likely to require histopathological assessment of the expression of receptor molecules and other signal transduction proteins within individual lesions to predict the effect of these treatments and thus assess patient eligibility. The identification of specific dysfunctions in signal transduction is also refining our recognition of specific diseases and disease subtypes. Cross-talk between pathways often regarded as linear is emerging as a key concept in our current understanding of signal transduction, and is of both biological and clinical relevance. This article reviews the biology of signal transduction, focusing on G-protein-coupled receptors, enzyme-linked receptors and steroid hormone receptors and their associated signal transduction pathways. The impact on diagnostic histopathology of advances in our understanding of these pathways is discussed, using the examples of the diagnosis of gastrointestinal stromal tumours and the assessment of prognosis and prediction of response to treatment in breast cancer.     

Opening the black box: the patient mix of GP trainees

Background

The variety of health problems (patient mix) that medical trainees encounter is presumed to be sufficient to masterthe required competencies.

Aim

To describe the patient mix of GP trainees, to study differences in patient mix between first-year and third-year GP trainees, and to investigate differences in exposure to sex-specific diseases between male and female trainees.

Design and setting

Prospective cohort study in Dutch primary care.

Method

During a 6-month period, aggregated data about International Classification of Primary Care diagnosis codes, and data on the sex and age of all contacts were collected from the electronic patient record (EPR) system.

Results

Seventy-three trainees participated in this study. The mean coding percentage was 86% and the mean number of face-to-face consultations per trimester was 450.0 in the first year and 485.4 in the third year, indicating greater variance in the number of patient contacts among third-year trainees. Diseases seen most frequently were: musculoskeletal (mean per trimester = 89.2 in the first year/91.0 in the third year), respiratory (98.2/92.7) and skin diseases (89.5/96.0). Least often seen were diseases of the blood and blood-forming organs (5.3/7.2), male genital disorders (6.1/7.1), and social problems (4.3/4.2). The mean number of chronic diseases seen per trimester was 48.0 for first-year trainees and 62.4 for third-year trainees. Female trainees saw an average of 39.8 female conditions per trimester — twice as many as male trainees (mean = 21.3).

Conclusion

Considerable variation exists trainees in the number of patient contacts. Differences in patient mix between first- and third-year trainees seem at least partly related to year-specific learning objectives. The use of an EPR-derived educational instrument provides insight into the trainees'' patient mix at both the group and the individual level. This offers opportunities for GP trainers, trainees, and curriculum designers to optimise learning when exposure may be low.     

Users' reports and evaluations of out-of-hours health care and the UK national quality requirements: a cross sectional study

Background

National standards for delivery of out-of-hours services have been refined. Health service users'' preferences, reports, and evaluations of care are of importance in a service that aims to be responsive to their needs.

Aim

To investigate NHS service users'' reports and evaluations of out-of-hours care in the light of UK national service quality requirements.

Design

Cross sectional survey.

Setting

Three areas (Devon, Cornwall, Sheffield) of England, UK.

Method

Participants were 1249 recent users of UK out-of-hours medical services. Main outcome measures were: users'' reports and evaluations of out-of-hours services in respect of the time waiting for their telephone call to the service to be answered; the length of time from the end of the initial call to the start of definitive clinical assessment (‘call back time’); the time waiting for a home visit; and the waiting time at a treatment centre.

Results

UK national quality requirements were reported as being met by two-thirds of responders. Even when responders reported that they had received the most rapid response option for home visiting (waiting time of ‘up to an hour’), only one-third of users reported this as ‘excellent’. Adverse evaluations of care were consistently related to delays encountered in receiving care and (for two out of four measures) sex of patient. For 50% of users to evaluate their care as ‘excellent’, this would require calls to be answered within 30 seconds, call-back within 20 minutes, time spent waiting for home visits of significantly less than 1 hour, and treatment centre waiting times of less than 20 minutes.

Conclusion

Users have high expectations of UK out-of-hours healthcare services. Service provision that meets nationally designated targets is currently judged as being of ‘good’ quality by service users. Attaining ‘excellent’ levels of service provision would prove challenging, and potentially costly. Delivering services that result in high levels of user satisfaction with care needs to take account of users'' expectations as well as their experience of care.     

Routine mortality monitoring for detecting mass murder in UK general practice: test of effectiveness using modelling.

BACKGROUND: The Shipman Inquiry recommended mortality rate monitoring if it could be 'shown to be workable' in detecting a future mass murderer in general practice. AIM: To examine the effectiveness of cumulative sum (CUSUM) charts, cross-sectional Shewhart charts, and exponentially-weighted, moving-average control charts in mortality monitoring at practice level. DESIGN OF STUDY: Analysis of Scottish routine general practice data combined with estimation of control chart effectiveness in detecting a 'murderer' in a simulated dataset. METHOD: Practice stability was calculated from routine data to determine feasible lengths of monitoring. A simulated dataset of 405,000 'patients' was created, registered with 75 'practices' whose underlying mortality rates varied with the same distribution as case-mix-adjusted mortality in all Scottish practices. The sensitivity of each chart to detect five and 10 excess deaths was examined in repeated simulations. The sensitivity of control charts to excess deaths in simulated data, and the number of alarm signals when control charts were applied to routine data were estimated. RESULTS: Practice instability limited the length of monitoring and modelling was consequently restricted to a 3-year period. Monitoring mortality over 3 years, CUSUM charts were most sensitive but only reliably achieved >50% successful detection for 10 excess deaths per year and generated multiple false alarms (>15%). CONCLUSION: At best, mortality monitoring can act as a backstop to detect a particularly prolific serial killer when other means of detection have failed. Policy should focus on changes likely to improve detection of individual murders, such as reform of death certification and the coroner system.     

Recorded quality of care for depression in general practice: an observational study

Background

Depression is a leading cause of disease and disability internationally, and is responsible for many primary care consultations. Little is known about the quality of primary care for depression in the UK.

Aim

To determine the prevalence of good-quality primary care for depression, and to analyse variations in quality by patient and practice characteristics.

Design of study

Retrospective observational study.

Setting

Eighteen general practices in England.

Method

Medical records were examined for 279 patients. The percentage of eligible participants diagnosed with depression who received the care specified by each of six quality indicators in 2002 and 2004 was assessed. Associations between quality achievement and age, sex, patient deprivation score, timepoint, and practice size were estimated using logistic regression.

Results

There was very wide variation in achievement of different indicators (range 1–97%). Achievement was higher for indicators referring to treatment and follow-up than for indicators referring to history taking. Achievement of quality indicators was low overall (37%). Quality did not vary significantly by patient or practice characteristics.

Conclusion

There is substantial scope for improvement in the quality of primary care for depression, if the highest achievement rates could be matched for all indicators. Given the lack of variation by practice characteristics, system-level and educational interventions may be the best ways to improve quality. The equitable distribution of quality by patient deprivation score is an important achievement that may be challenging to maintain as quality improves.     

Weakly supervised annotation-free cancer detection and prediction of genotype in routine histopathology

Deep learning is a powerful tool in computational pathology: it can be used for tumor detection and for predicting genetic alterations based on histopathology images alone. Conventionally, tumor detection and prediction of genetic alterations are two separate workflows. Newer methods have combined them, but require complex, manually engineered computational pipelines, restricting reproducibility and robustness. To address these issues, we present a new method for simultaneous tumor detection and prediction of genetic alterations: The Slide-Level Assessment Model (SLAM) uses a single off-the-shelf neural network to predict molecular alterations directly from routine pathology slides without any manual annotations, improving upon previous methods by automatically excluding normal and non-informative tissue regions. SLAM requires only standard programming libraries and is conceptually simpler than previous approaches. We have extensively validated SLAM for clinically relevant tasks using two large multicentric cohorts of colorectal cancer patients, Darmkrebs: Chancen der Verhütung durch Screening (DACHS) from Germany and Yorkshire Cancer Research Bowel Cancer Improvement Programme (YCR-BCIP) from the UK. We show that SLAM yields reliable slide-level classification of tumor presence with an area under the receiver operating curve (AUROC) of 0.980 (confidence interval 0.975, 0.984; n = 2,297 tumor and n = 1,281 normal slides). In addition, SLAM can detect microsatellite instability (MSI)/mismatch repair deficiency (dMMR) or microsatellite stability/mismatch repair proficiency with an AUROC of 0.909 (0.888, 0.929; n = 2,039 patients) and BRAF mutational status with an AUROC of 0.821 (0.786, 0.852; n = 2,075 patients). The improvement with respect to previous methods was validated in a large external testing cohort in which MSI/dMMR status was detected with an AUROC of 0.900 (0.864, 0.931; n = 805 patients). In addition, SLAM provides human-interpretable visualization maps, enabling the analysis of multiplexed network predictions by human experts. In summary, SLAM is a new simple and powerful method for computational pathology that could be applied to multiple disease contexts. © 2021 The Authors.

Overall quality of diabetes care in a defined geographic region: different sides of the same story.

BACKGROUND: In diabetes care, knowledge about what is achievable in primary and secondary care is important. There is a need for an objective method to assess the quality of care in different settings. A quality-of-care summary score has been developed based on process and outcome measures. An adapted version of this score was used to evaluate diabetes management in different settings. AIM: To evaluate the quality of diabetes management in primary and secondary care in a defined geographic region in the Netherlands, using a quality score. DESIGN OF STUDY: Cross-sectional study. SETTING: Thirty general practices in the Netherlands. METHOD: A study of 2042 patients with type 2 diabetes (1640 primary care and 402 secondary care) was conducted. Quality of diabetes management was assessed by a score of process and outcome indicators (range 0-40). Clustering at practice level and differences in patient characteristics (case mix) were taken into account. RESULTS: At the outpatient clinic, patients were younger (mean age 64.1 years, standard deviation (SD)=12.5 years, versus mean age 67.1 years, SD=11.7, P<0.001), had more diabetes-related complications (macrovascular: 39.7% versus 24.3%, P<0.001; and microvascular: 25.9% versus 7.3%, P<0.001), and lower quality-of-life scores (EuroQol-5D: mean=0.60, SD=0.29, versus mean=0.80, SD=0.21, P<0.001). After adjusting for case mix and clustering, there was a weak association between the setting of treatment and haemoglobin A1c (primary care: mean 7.1%, SD=1.1, versus secondary care: mean 7.6%, SD=1.2, P<0.016), and between setting and systolic blood pressure (primary: mean 145.7 mmHg, SD=19.2, versus secondary care: 147.77 mmHg, SD 21.0, P<0.035). Quality-of-care summary scores in primary and secondary care differed significantly, with a higher score in primary care (mean 19.6, SD=8.5 versus, mean 18.1, SD=8.7, P<0.01). However, after adjusting for case mix and clustering, this difference lost significance. CONCLUSION: GPs and internists are treating different categories of patients with type 2 diabetes. However, overall quality of diabetes management in primary and secondary care is equal. There is much room for improvement. Future guidelines may differentiate between different categories of patients.
