The social vulnerability metric (SVM) as a new tool for public health

Objective

To derive and validate a new ecological measure of the social determinants of health (SDoH), calculable at the zip code or county level.

Data Sources and Study Setting

The most recent releases of secondary, publicly available data were collected from national U.S. health agencies as well as state and city public health departments.

Study Design

The Social Vulnerability Metric (SVM) was constructed from U.S. zip-code level measures (2018) from survey data using multidimensional Item Response Theory and validated using outcomes including all-cause mortality (2016), COVID-19 vaccination (2021), and emergency department visits for asthma (2018). The SVM was also compared with the existing Centers for Disease Control and Prevention's Social Vulnerability Index (SVI) to determine convergent validity and differential predictive validity.

Data Collection/Extraction Methods

The data were collected directly from published files available to the public online from national U.S. health agencies as well as state and city public health departments.

Principal Findings

The correlation between SVM scores and national age-adjusted county all-cause mortality was r = 0.68. This correlation demonstrated the SVM's robust validity and outperformed the SVI with an almost four-fold increase in explained variance (46% vs. 12%). The SVM was also highly correlated (r ≥ 0.60) to zip-code level health outcomes for the state of California and city of Chicago.

Conclusions

The SVM offers a measurement tool improving upon the performance of existing SDoH composite measures and has broad applicability to public health that may help in directing future policies and interventions. The SVM provides a single measure of SDoH that better quantifies associations with health outcomes.     

Post-cardiac arrest intensive care in Sweden: A survey of current clinical practice

Background

European guidelines recommend targeted temperature management (TTM) in post-cardiac arrest care. A large multicentre clinical trial, however, showed no difference in mortality and neurological outcome when comparing hypothermia to normothermia with early treatment of fever. The study results were valid given a strict protocol for the assessment of prognosis using defined neurological examinations. With the current range of recommended TTM temperatures, and applicable neurological examinations, procedures may differ between hospitals and the variation of clinical practice in Sweden is not known.

Aim

The aim of this study was to investigate current practice in post-resuscitation care after cardiac arrest as to temperature targets and assessment of neurological prognosis in Swedish intensive care units (ICUs).

Methods

A structured survey was conducted by telephone or e-mail in all Levels 2 and 3 (= 53) Swedish ICUs during the spring of 2022 with a secondary survey in April 2023.

Results

Five units were not providing post-cardiac arrest care and were excluded. The response rate was 43/48 (90%) of the eligible units. Among the responding ICUs, normothermia (36–37.7°C) was applied in all centres (2023). There was a detailed routine for the assessment of neurological prognosis in 38/43 (88%) ICUs. Neurological assessment was applied 72–96 h after return of spontaneous circulation in 32/38 (84%) units. Electroencephalogram and computed tomography and/or magnetic resonance imaging were the most common technical methods available.

Conclusion

Swedish ICUs use normothermia including early treatment of fever in post-resuscitation care after cardiac arrest and almost all apply a detailed routine for the assessment of neurological prognosis. However, available methods for prognostic evaluation varies between hospitals.

Contraception use and knowledge related to pregnancy in diabetic women

BackgroundDiabetes mellitus prevalence is increasing among women of child-bearing age. Diabetic pregnancy is associated with major maternal and fetal risks, and these can be reduced by preconception care. Pregnancy can be planned using appropriate effective contraception. The objective of this study was to assess diabetic patients’ knowledge about pregnancy and to describe their contraceptive use.Study designAn observational study was conducted from February to July 2020 at Reims University Hospital, France. Inclusion criteria were: women aged 18 to 40 years, with type 1 (T1D) or type 2 diabetes (T2D). Patients filled out a survey about contraceptive use and knowledge regarding diabetic pregnancy and data were completed from medical records.ResultsEighty-nine T1D and 33 T2D patients were included, with mean ages of 27.9 ± 6.3 and 32.6 ± 4.6 years, respectively. Seventy-five percent reported that they had been informed about pregnancy-related risks and 67% about the need to plan pregnancy. The preconception HbA1c target was known by 33% of patients. Appropriate knowledge about pregnancy was greater in T1D patients (65.9%, versus 36.4% in T2D patients; P = 0.003). The rate of patients using an effective contraceptive method was 66.4%. Fifteen percent patients for whom contraception was recommended reported having no contraceptive method; 12.5% of contraception users were using a contraindicated method.ConclusionA large majority of diabetic women were aware of pregnancy-related risks and the importance of pregnancy planning, but there are still gaps, especially in T2D patients. We need to improve our practices by providing more information and better access to appropriate effective contraception.ClinicalTrials.gov numberNCT04350879.     

Efficacy of an eConsult service to cure hepatitis C in primary care

In 2016, an eConsult service was developed within a safety net health system to expand access to hepatitis C (HCV) treatment in the primary care setting. The eConsult system provides individualized treatment recommendations from specially trained primary care pharmacists and primary care physicians to primary care providers with less experience in the rapidly changing treatment of HCV. Since its launch, this service has had a large impact in expanding care to a largely homeless and low-income urban population within our health system. We now aim to evaluate its efficacy in curing HCV. In this retrospective cohort study, we describe rates of sustained virologic response 12 weeks after treatment completion (SVR12) for those who received primary care-based HCV treatment through the eConsult system with those who were treated in primary care independent of an eConsult from 2017 to 2019. We found there was no significant difference in the proportion of patients who achieved SVR12 between the two groups. Overall, >90% of patients who received treatment achieved SVR12. Approximately 40% of patients treated for HCV received an eConsult, suggesting utility of the eConsult in expanding access and coordinating treatment for patients within our network.     

‘It felt like there was always someone there for us’: Supporting children affected by domestic violence and abuse who are identified by general practice

One in five children in the UK are affected by domestic violence and abuse. However, primary care clinicians (GPs and nurses) struggle to effectively identify and support children and young people living in homes where it is present. The IRIS+ (Enhanced Identification and Referral to Improve Safety) training and advocacy support intervention aimed to improve how clinicians respond to children and young people affected by domestic violence and abuse. IRIS+ training was delivered as part of a feasibility study to four general practices in an urban area in England (UK). Our mixed method design included interviews and questionnaires about the IRIS+ intervention with general practice patients, including children and young people as well as with clinicians and advocacy service providers. We collected the number of identifications and referrals by clinicians of children experiencing domestic violence and abuse through a retrospective search of medical and agency records 10 months after the intervention. Forty-nine children exposed to domestic violence and abuse were recorded in medical records. Thirty-five children were referred to a specialist domestic violence and abuse support service over a period of 10 months. Of these, 22 received direct or indirect support. The qualitative findings indicated that children benefitted from being referred by clinicians to the service. However, several barriers at the patient and professional level prevented children and young people from being identified and supported. Some of these barriers can be addressed through modifications to professional training and guidance, but others require systematic and structural changes to the way health and social care services work with children affected by domestic violence and abuse.     

Characterizing Standardized Functional Data at Inpatient Rehabilitation Facilities

ObjectiveThe Improving Medicare Post-Acute Care Transformation Act of 2014 mandates using standardized patient functional data across post-acute settings. This study characterized similarities and differences in clinician-observed scores of self-care and transfer items for the standardized section GG functional domain and the functional independent measure (FIM) at inpatient rehabilitation facilities.DesignWe conducted secondary analyses of 2017 Uniform Data System for Medical Rehabilitation national data. Patients were assessed by clinicians on both section GG and FIM at admission and discharge. We identified 7 self-care items and 6 transfer items in section GG conceptually equivalent with FIM. Clinician-assessed scores for each pair of items were examined using score distributions, Bland-Altman plot, correlation (Pearson coefficients), and agreement (kappa and weighted kappa) analyses.Setting and ParticipantsIn all, 408,491 patients were admitted to Uniform Data System for Medical Rehabilitation-affiliated inpatient rehabilitation facilities with one of the following impairments: stroke, brain dysfunction, neurologic condition, orthopedic disorders, and debility.MeasuresSection GG and FIM.ResultsPatients were scored as more functionally independent in section GG compared with FIM, but change score distributions and score orders within impairment groups were similar. Total scores in section GG had strong positive correlations (self-care: r = 0.87 and 0.95; transfer: r = 0.82 and 0.90 at admission and discharge, respectively) with total FIM scores. Weak to moderate ranking agreements with total FIM scores were observed (self-care: kappa = 0.49 and 0.60; transfers: kappa = 0.43 and 0.52 at admission and discharge, respectively). Lower agreements were observed for less able patients at admission and for higher ability patients of their change scores.Conclusions and ImplicationsOverall, response patterns were similar in section GG and FIM across impairments. However, variations exist in score distributions and ranking agreement. Future research should examine the use of GG codes to maintain effective care, outcomes, and unbiased reimbursement across post-acute settings.
