Human-centred explanations for artificial intelligence systems

As Artificial Intelligence (AI) systems increase in capability, so there are growing concerns over the ways in which the recommendations they provide can affect people's everyday life and decisions. The field of Explainable AI (XAI) aims to address such concerns but there is often a neglect of the human in this process. We present a formal definition of human-centred XAI and illustrate the application of this formalism to the design of a user interface. The user interface supports users in indicating their preferences relevant to a situation and to compare their preferences with those of a computer recommendation system. A user trial is conducted to evaluate the resulting user interface. From the user trial, we believe that users are able to appreciate how their preferences can influence computer recommendations, and how these might contrast with the preferences used by the computer. We provide guidelines of implementing human-centred XAI.

Childhood-Onset Lupus Nephritis in the Childhood Arthritis and Rheumatology Research Alliance Registry: Short-Term Kidney Status and Variation in Care

OBJECTIVE

The goal was to characterize short-term kidney status and describe variation in early care utilization in a multicenter cohort of patients with childhood-onset systemic lupus erythematosus (cSLE) and nephritis.

METHODS

We analyzed previously collected prospective data from North American patients with cSLE with kidney biopsy-proven nephritis enrolled in the Childhood Arthritis and Rheumatology Research Alliance (CARRA) Registry from March 2017 through December 2019. We determined the proportion of patients with abnormal kidney status at the most recent registry visit and applied generalized linear mixed models to identify associated factors. We also calculated frequency of medication use, both during induction and ever recorded.

RESULTS

We identified 222 patients with kidney biopsy-proven nephritis, with 64% class III/IV nephritis on initial biopsy. At the most recent registry visit at median (interquartile range) of 17 (8-29) months from initial kidney biopsy, 58 of 106 patients (55%) with available data had abnormal kidney status. This finding was associated with male sex (odds ratio [OR] 3.88, 95% confidence interval [95% CI] 1.21-12.46) and age at cSLE diagnosis (OR 1.23, 95% CI 1.01-1.49). Patients with class IV nephritis were more likely than class III to receive cyclophosphamide and rituximab during induction. There was substantial variation in mycophenolate, cyclophosphamide, and rituximab ever use patterns across rheumatology centers.

CONCLUSION

In this cohort with predominately class III/IV nephritis, male sex and older age at cSLE diagnosis were associated with abnormal short-term kidney status. We also observed substantial variation in contemporary medication use for pediatric lupus nephritis between pediatric rheumatology centers. Additional studies are needed to better understand the impact of this variation on long-term kidney outcomes.

Measuring occupational stress in emergency departments

OBJECTIVE

EDs are highly demanding workplaces generating considerable potential for occupational stress experiences. Previous research has been limited by a focus on specific aspects of the working environment and studies focussing on a range of variables are needed. The aim of the present study was to describe the perceptions of occupational stress and coping strategies of ED nurses and doctors and the differences between these two groups.

METHODS

This cross-sectional study was conducted at a public metropolitan hospital ED in Queensland, Australia. All ED nurses and doctors were invited to participate in an electronic survey containing 13 survey measures and one qualitative question assessing occupational stress and coping experiences. Descriptive statistics were employed to report stressors. Responses to open-ended questions were thematically analysed.

RESULTS

Overall, 104 nurses and 35 doctors responded (55.6% response rate). Nurses reported higher levels of both stress and burnout than doctors. They also reported lower work satisfaction, work engagement, and leadership support than doctors. Compared with doctors, nurses reported significantly higher stress from heavy workload/poor skill mix, high acuity patients, environmental concerns, and inability to provide optimal care. Thematic analysis identified high workload and limited leadership and management support as factors contributing to stress. Coping mechanisms, such as building personal resilience, were most frequently reported.

CONCLUSIONS

The present study found organisational stressors adversely impact the well-being of ED nurses and doctors. Organisational-focused interventions including leadership development, strategic recruitment, adequate staffing and resources may mitigate occupational stress and complement individual coping strategies. Expanding this research to understand broader perspectives and especially the impact of COVID-19 upon ED workers is recommended.

Intraarticular steroids as DMARD-sparing agents for juvenile idiopathic arthritis flares: Analysis of the Childhood Arthritis and Rheumatology Research Alliance Registry

BACKGROUND

Children with juvenile idiopathic arthritis (JIA) who achieve a drug free remission often experience a flare of their disease requiring either intraarticular steroids (IAS) or systemic treatment with disease modifying anti-rheumatic drugs (DMARDs). IAS offer an opportunity to recapture disease control and avoid exposure to side effects from systemic immunosuppression. We examined a cohort of patients treated with IAS after drug free remission and report the probability of restarting systemic treatment within 12 months.

METHODS

We analyzed a cohort of patients from the Childhood Arthritis and Rheumatology Research Alliance (CARRA) Registry who received IAS for a flare after a period of drug free remission. Historical factors and clinical characteristics and of the patients including data obtained at the time of treatment were analyzed.

RESULTS

We identified 46 patients who met the inclusion criteria. Of those with follow up data available 49% had restarted systemic treatment 6 months after IAS injection and 70% had restarted systemic treatment at 12 months. The proportion of patients with prior use of a biologic DMARD was the only factor that differed between patients who restarted systemic treatment those who did not, both at 6 months (79% vs 35%, p < 0.01) and 12 months (81% vs 33%, p < 0.05).

CONCLUSION

While IAS are an option for all patients who flare after drug free remission, it may not prevent the need to restart systemic treatment. Prior use of a biologic DMARD may predict lack of success for IAS. Those who previously received methotrexate only, on the other hand, are excellent candidates for IAS.

Social determinants of health influence disease activity and functional disability in Polyarticular Juvenile Idiopathic Arthritis

BACKGROUND

Social determinants of health (SDH) greatly influence outcomes during the first year of treatment in rheumatoid arthritis, a disease similar to polyarticular juvenile idiopathic arthritis (pJIA). We investigated the correlation of community poverty level and other SDH with the persistence of moderate to severe disease activity and functional disability over the first year of treatment in pJIA patients enrolled in the Childhood Arthritis and Rheumatology Research Alliance Registry.

METHODS

In this cohort study, unadjusted and adjusted generalized linear mixed effects models analyzed the effect of community poverty and other SDH on disease activity, using the clinical Juvenile Arthritis Disease Activity Score-10, and disability, using the Child Health Assessment Questionnaire, measured at baseline, 6, and 12 months.

RESULTS

One thousand six hundred eighty-four patients were identified. High community poverty (≥20% living below the federal poverty level) was associated with increased odds of functional disability (OR 1.82, 95% CI 1.28-2.60) but was not statistically significant after adjustment (aOR 1.23, 95% CI 0.81-1.86) and was not associated with increased disease activity. Non-white race/ethnicity was associated with higher disease activity (aOR 2.48, 95% CI: 1.41-4.36). Lower self-reported household income was associated with higher disease activity and persistent functional disability. Public insurance (aOR 1.56, 95% CI 1.06-2.29) and low family education (aOR 1.89, 95% CI 1.14-3.12) was associated with persistent functional disability.

CONCLUSION

High community poverty level was associated with persistent functional disability in unadjusted analysis but not with persistent moderate to high disease activity. Race/ethnicity and other SDH were associated with persistent disease activity and functional disability.

Finding people like me: contact among young adults who share an open-identity sperm donor

STUDY QUESTION

What interests and experiences do donor-conceived adults have with respect to same-donor peers/siblings, when they share an open-identity sperm donor?

SUMMARY ANSWER

Donor-conceived young adults report considerable interest in, and primarily positive experiences with, their same-donor peers, with some finding ‘people like me’.

WHAT IS KNOWN ALREADY

Through mutual-consent contact registries, director-to-consumer DNA testing and other means, donor-conceived people with anonymous (i.e. closed-identity) sperm donors are gaining identity-related information from, and establishing relationships with, people who share their donor.

STUDY DESIGN, SIZE, DURATION

Semi-structured, in depth telephone and Skype interviews with 47 donor-conceived young adults were carried out over a 31-month period. Inclusion criteria were being one of the first adults for each donor to obtain their identity and being at least 1-year post donor-information release.

PARTICIPANTS/MATERIALS, SETTING, METHODS

Participants (aged 19–29 years, 68.1% women) were born to female same-sex couple parents (46.8%), a single mother (29.8%) or heterosexual couple parents (23.4%); all parents had conceived through the same US open-identity sperm donation program. The dataset was analyzed thematically and included interviews from only one participant per family. Each participant had a different donor.

MAIN RESULTS AND THE ROLE OF CHANCE

Interest in, and experiences with, same-donor peers suggested that they occupy a unique position in the lives of donor-conceived young adults who share their open-identity donor. Contact can provide identity-relevant information and support through the availability of relationships (whether actualized or potential), shared experiences, and easier relationships than with their donor. Most donor-conceived young adults felt positively about their contact experiences. Of those not yet linked, almost all expressed an interest to do so. Some had met the children raised by their donor. When asked, all expressed an interest in doing so.

LIMITATIONS, REASONS FOR CAUTION

Interviews were conducted with donor-conceived young adults who were uncommon in their generation in terms of: having an open-identity sperm donor; the majority knowing about their family’s origins from childhood; and having parents that accessed at the time one of the only open-identity sperm donation programs. Further research is needed to assess applicability to all donor-conceived adults; findings may be more relevant to the growing number of people who have an open-identity donor and learned in childhood about their family’s origins.

WIDER IMPLICATIONS OF THE FINDINGS

Participants were among the first generation of donor-conceived adults with an open-identity sperm donor. Their experiences and perspectives can provide essential guidance to programs and others with similar origins. Early disclosure of family origins and identifying the donor did not diminish the young adults’ interest in their same-donor peers. Positive experiences suggest that the benefits of contact include not only identity-relevant information (through shared traits and experiences), but also relationships with and support from people who understand the uncommon experience of being donor conceived. Implications include the need to educate families and intended parents about the potential benefits of knowing others who are donor conceived, and the risk of unexpected linking across families by donors, regardless of donor-conceived person or family interest.

The Perirolandic Sign: A Unique Imaging Finding Observed in Association with Polymerase γ-Related Disorders

Pathogenic variants in the polymerase γ gene (POLG) cause a diverse group of pathologies known as POLG-related disorders. In this report, we describe brain MR imaging findings and electroencephalogram correlates of 13 children with POLG-related disorders at diagnosis and follow-up. At diagnosis, all patients had seizures and 12 had abnormal MR imaging findings. The most common imaging findings were unilateral or bilateral perirolandic (54%) and unilateral or bilateral thalamic signal changes (77%). Association of epilepsia partialis continua with perirolandic and thalamic signal changes was present in 86% and 70% of the patients, respectively. The occipital lobe was affected in 2 patients. On follow-up, 92% of the patients had disease progression or fatal outcome. Rapid volume loss was seen in 77% of the patients. The occipital lobe (61%) and thalamus (61%) were the most affected brain regions. Perirolandic signal changes and seizures may represent a brain imaging biomarker of early-onset pediatric POLG-related disorders.

Utilization care plans and effective patient data management

This article introduces the concept of a utilization care plan (UCP) for supporting the communication of data required for effective utilization review and utilization management. Utilization review is a process of measurement that compares the performance of a ward, department, or entire facility against accepted criteria to identify resource use shortfalls. Utilization management is the deliberate action by third party payers to ensure that shortfalls in resource utilization are minimized. Critical to the success of utilization management is effective data communication; utilization review data must be accurate, complete, accessible, timely, and coordinated. Computer-based UCP systems can remind caregivers when and what services should be provided to patients and also monitor the portion of those services that should be administered during each phase of a patient's therapy. Deviations from the UCP system template constitute variances that can be documented and highlighted in a friendly automated system that ensures highly accurate and extremely timely concurrent utilization information. Some implications of using UCP systems for future research and practice are also discussed.

Pharmacokinetics of ciprofloxacin in subjects with varying degrees of renal function and undergoing hemodialysis or CAPD

The pharmacokinetics of a single, oral dose of 750 mg of ciprofloxacin were studied in 35 subjects with various degrees of renal function (Group 1, Clcr > or = 80 ml/min; Group II, Clcr 50-79 ml/min; Group III, Clcr 10-49 ml/min) and on hemodialysis (HD) or continuous ambulatory peritoneal dialysis (CAPD). Blood, urine and CAPD dialysate samples were collected over a period of 48 hours after dosing. Data were fitted using non-linear, least squares regression. The mean Cmax was 3.4 +/- 1.0 mg/l and tmax was 2.3 +/- 0.9 hours. The mean AUC in Group I was 14.7 mg.h/l, Group II was 33.7 (p < 0.001), Group III 63.8 (p < 0.001), HD 57.9 (p < 0.0001) and CAPD 44.3 (p < 0.001). Half-life in Group I was 4.6 h, and was shorter than Group III (11.1 h, p < 0.001), HD (13.4 h, p < 0.001) and CAPD (8.9 h, p < 0.001). Total body clearance and renal clearance demonstrated significant differences also. The dialysis clearance in CAPD patients was 0.53 +/- 0.39 l/h. Peritoneal effluent concentrations varied from 0.6 mg/l during the first exchange, to a peak of 2.2 mg/l during the second, to 0.13 mg/l in the 48 hour (9th) exchange. Dosage adjustments of ciprofloxacin in the presence of renal insufficiency are indicated for subjects with a Clcr < 20 ml/min/1.73m2.

Evaluation of impairment of the upper extremity

Evaluation of impairment of the upper extremity is the product of a team effort by the physician, occupational therapist, physical therapist, and rehabilitation counselor. A careful recording of the anatomic impairment should be made because this is critical in determining the subsequent functional activities of the extremity. The measurement criteria for clinical and functional evaluation includes condition assessment instruments. Some assess the neurovascular system, others assess movements including the monitoring of articular motion and musculotendinous function. Sensibility assessment instruments measure sympathetic response and detect single joint stimulus, discrimination, quantification, and recognition abilities. A detailed description of each assessment is recorded and physical capacity evaluation is only one component of the entire vocational evaluation. This evaluation answers questions regarding the injured worker's ability to return to his previous job. The work simulator is a useful instrument that allows rehabilitation and testing of the injured upper extremity. Job site evaluation includes assessment criteria for work performance, work behavior, and work environment.

The expanding role of occupational therapy in the treatment of industrial hand injuries

A recent survey of members of the American Society of Hand Therapists revealed an expanding role for the therapist in the treatment of industrial hand injuries. In the traditional role of treatment provider, occupational therapists are using their assessment tools and work capacity programming to aid in predicting return to work readiness. This is aimed at preventing reinjury of the present patient population. In addition to this, therapists have begun to identify relationships between specific injuries and work that produced them. This gives rise to a specified goal of preventing the injury from ever occuring. To reach this goal therapists are becoming involved in industrial settings and are working with industrial safety teams.
