An E-learning Module on Chronic Low Back Pain in Older Adults: Effect on Medical Resident Attitudes, Confidence, Knowledge, and Clinical Skills.

Objective: To determine 1) the feasibility of implementing an e-learning module on chronic low back pain (CLBP) in an older adult into an existing internal medicine residency curriculum and 2) the impact of this module on resident attitudes, confidence, knowledge, and clinical skills relating to CLBP. Methods: Participants were assigned to complete either the online module (N = 73) or the Yale Office-based curriculum on CLBP (N = 70). Attitudes, confidence, and knowledge were evaluated pre- and postintervention via survey. A retrospective blinded chart review of resident clinic encounters was conducted, wherein diagnosis codes and physical exam documentation were rated as basic or advanced. Results: There was no improvement in overall knowledge scores in either group (60% average on both metrics). There were tendencies for greater improvements in the intervention group compared with controls for confidence in managing fibromyalgia (2.4 to 2.9 vs 2.5 to 2.5, P = 0.06) and leg length discrepancy (1.8 to 2.5 vs 1.5 to 1.9, P = 0.05). Those exposed to the online module also showed an increase in the percentage of physical exam documentation rated as advanced following the intervention (13% to 32%, P = 0.006), whereas the control group showed no change (14% to 12%, P = 0.68). Conclusions: An online module on CLBP in the older adult was a feasible addition to an existing curriculum for internal medicine residents. The module positively and substantively impacted resident clinical behaviors, as evidenced by enhanced sophistication in physical exam documentation; it also was associated with improved confidence in certain aspects of chronic pain management.

Isolation.

This comic tells the true story of a hospitalist physician learning from a patient how to slow down. It is a commentary on the isolating experience of hospitalization-magnified for patients by infection control precautions and hospital restrictions and for clinicians by long hours away from family and friends, particularly during peaks of the COVID-19 pandemic.

Subtle case of dapsone-induced methaemoglobinaemia.

Methaemoglobinaemia is a rare disease that is typically caused by a medication or other exogenous agent, with dapsone being the most common. It occurs when the concentration of methaemoglobin rises via ferrous haeme irons becoming oxidised to the ferric state, which shifts the oxygen dissociation curve to the left. The net result of an elevated methaemoglobin concentration is functional anaemia and impaired oxygen delivery to tissues. At lower blood levels, this can cause symptoms such as cyanosis, lethargy, headache and fatigue, whereas at higher levels it can be fatal. Here we discuss a subtle case of dapsone-induced methaemoglobinaemia presenting as subacute mental status changes and apparent hypoxia, thus highlighting the association between methaemoglobinaemia and dapsone. This case demonstrates the importance of thorough medication reconciliation and maintaining a broad differential diagnosis, while also recognising the significance of conflicting data and their implications for the workup.

The Association between Limited English Proficiency and Sepsis Mortality.

BACKGROUND: Limited English proficiency (LEP) has been implicated in poor health outcomes. Sepsis is a frequently fatal syndrome that is commonly encountered in hospital medicine. The impact of LEP on sepsis mortality is not currently known. OBJECTIVE: To determine the association between LEP and sepsis mortality. DESIGN: Retrospective cohort study. SETTING: 800-bed, tertiary care, academic medical center. PATIENTS: Electronic health record data were obtained for adults admitted to the hospital with sepsis between June 1, 2012 and December 31, 2016. MEASUREMENTS: The primary predictor was LEP. Patients were defined as having LEP if their self-reported primary language was anything other than English and interpreter services were required during hospitalization. The primary outcome was inpatient mortality. Mortality was compared across races stratified by LEP using chi-squared tests of significance. Bivariable and multivariable logistic regressions were performed to investigate the association between mortality, race, and LEP, adjusting for baseline characteristics, comorbidities, and illness severity. RESULTS: Among 8,974 patients with sepsis, we found that 1 in 5 had LEP, 62% of whom were Asian. LEP was highly associated with death across all races except those identifying as Black and Latino. LEP was associated with a 31% increased odds of mortality after adjusting for illness severity, comorbidities, and other baseline characteristics, including race (OR 1.31, 95% CI 1.06-1.63, P = .02). CONCLUSIONS: In a single-center study of patients hospitalized with sepsis, LEP was associated with mortality across nearly all races. This is a novel finding that will require further exploration into the causal nature of this association.

Management of Elevated Blood Pressure in the Hospital-Rethinking Current Practice.

This Clinical Insight proposes a new framework for managing asymptomatic blood pressure elevation in the hospital setting.

Reducing Unnecessary Treatment of Asymptomatic Elevated Blood Pressure with Intravenous Medications on the General Internal Medicine Wards: A Quality Improvement Initiative.

BACKGROUND: Asymptomatic elevated blood pressure (BP) is common in the hospital. There is no evidence supporting the use of intravenous (IV) antihypertensives in this setting. OBJECTIVE: To determine the prevalence and effects of treating asymptomatic elevated BP with IV antihypertensives and to investigate the efficacy of a quality improvement (QI) initiative aimed at reducing utilization of these medications. DESIGN: Retrospective cohort study. SETTING: Urban academic hospital. PATIENTS: Patients admitted to the general medicine service, including the intensive care unit (ICU), with ≥1 episode of asymptomatic elevated BP (>160/90 mm Hg) during hospitalization. INTERVENTION: A two-tiered, QI initiative. MEASUREMENTS: The primary outcome was the monthly proportion of patients with asymptomatic elevated BP treated with IV labetalol or hydralazine. We also analyzed median BP and rates of balancing outcomes (ICU transfers, rapid responses, cardiopulmonary arrests). RESULTS: We identified 2,306 patients with ≥1 episode of asymptomatic elevated BP during the 10-month preintervention period, of which 251 (11%) received IV antihypertensives. In the four-month postintervention period, 70 of 934 (7%) were treated. The odds of being treated were 38% lower in the postintervention period after adjustment for baseline characteristics, including length of stay and illness severity (OR = 0.62; 95% CI 0.47-0.83; P = .001). Median SBP was similar between pre- and postintervention (167 vs 168 mm Hg; P = .78), as were the adjusted proportions of balancing outcomes. CONCLUSIONS: Hospitalized patients with asymptomatic elevated BP are commonly treated with IV antihypertensives, despite the lack of evidence. A QI initiative was successful at reducing utilization of these medications.

Harmonin (Ush1c) is required in zebrafish Müller glial cells for photoreceptor synaptic development and function.

Usher syndrome is the most prevalent cause of hereditary deaf-blindness, characterized by congenital sensorineural hearing impairment and progressive photoreceptor degeneration beginning in childhood or adolescence. Diagnosis and management of this disease are complex, and the molecular changes underlying sensory cell impairment remain poorly understood. Here we characterize two zebrafish models for a severe form of Usher syndrome, Usher syndrome type 1C (USH1C): one model is a mutant with a newly identified ush1c nonsense mutation, and the other is a morpholino knockdown of ush1c. Both have defects in hearing, balance and visual function from the first week of life. Histological analyses reveal specific defects in sensory cell structure that are consistent with these behavioral phenotypes and could implicate Müller glia in the retinal pathology of Usher syndrome. This study shows that visual defects associated with loss of ush1c function in zebrafish can be detected from the onset of vision, and thus could be applicable to early diagnosis for USH1C patients.
