Association between Elevated Plasma Vitamin B12 and Short-Term Mortality in Elderly Patients Hospitalized in an Internal Medicine Unit

Background

The prognostic value of vitamin B12 blood levels remains controversial. An association between elevated vitamin B12 and mortality has been reported, particularly among elderly patients with cancers and liver or blood diseases. The present study explored the relationship between mortality and elevated vitamin B12 levels in a population of unscheduled inpatients in an internal medicine unit.

Methods

This retrospective observational analysis was conducted between August 2014 and December 2018. We compared 165 patients with elevated plasma vitamin B12 levels (>600 pmol/l) with a random sample of 165 patients with normal B12 levels who were hospitalized during the same period. Demographic, clinical, and biological characteristics were assessed during hospitalization. The primary endpoint was all-cause death at 1 year.

Results

Patients with elevated B12 were younger, with a lower body mass index and lower plasma albumin than those with normal B12 (75 ± 16 years vs 79 ± 13 years, p = 0.047; 23 ± 5 vs 26 ± 7 kg/m2, p  <  0.001; and 33 ± 5 vs 35 ± 5 g/l, p  <  0.001, respectively). The prevalence of auto-immune disease and referral from an intensive care unit was higher among patients with elevated B12 (11% vs 5%, p = 0.043 and 36% vs 10%, p  <  0.001, respectively). After 1 year of follow-up, 64 (39%) patients with elevated B12 had died compared to 43 (26%) patients with normal B12 (p = 0.018). Multivariate analysis using the Cox proportional hazards regression model adjusted for age, gender, body mass index, intensive care unit hospitalization, albumin level, and the presence of solid cancer or autoimmune disease revealed elevated B12 to be associated with a significant risk of death in the first year of follow-up (hazard ratio: 1.71 [1.08-2.7], p = 0.022).

Conclusion

Elevated B12 is an early warning indicator of increased short-term mortality, such as independently of age, cancer, or comorbidities, in patients hospitalized in an internal medicine department.

[Place of internal medicine specialists in inpatient unprogrammed care of adult patients in France: A survey of in training and senior internal medicine specialists]

INTRODUCTION

French internal medicine specialists are trained in clinical immunology and rare diseases as well as frequent ones. The latest activity is rarely highlighted by practitioners themselves and their representative authorities. Frequent diseases care in French hospitals are also the tasks of physicians without internal medicine specialty, mostly trained in general medicine, who practice in departments carrying various names.

METHODS

We conducted a survey to estimate the part of frequent diseases' care and unplanned hospital medicine in the practice of specialists and residents in internal medicine in France, and its designation, through two surveys released by the "Collège National Professionnel de Médecine Interne" (for the internal medicine specialists), and the "Amicale des Jeunes Internists" (for the internal medicine residents).

RESULTS

A total of 180 and 247 responses were obtained among the residents and the specialists, respectively, representing 31.3% and 24.8% of the internal medicine specialist's workforce. The most suitable qualifier for frequent diseases' care and unplanned hospital medicine, primarily post-emergency, was "general hospital medicine" for 48.9% of the residents and "general internal medicine" for 35.6% of the specialists. Unplanned hospital medicine was considered to represent a large part of the internal medicine activity by 66.7% and 64.7% of residents and specialists, respectively. A 50% and more hourly part of the activity devoted to it was reported by 71.4% of the residents and 76.1% of the specialists. General hospital medicine was reported to be distinct from internal medicine-clinical immunology by 46.1% of the residents and 47.4% of the specialists.

CONCLUSION

French internists devote a large part of their activities to frequent diseases' care and unscheduled medicine, the name of which was not consensual. However, their work could not be summarized to it, often involving a specific activity named internal medicine - clinical immunology.

Work Climate Scale in Emergency Services: Abridged Version

This study is based on a 40-item work climate scale in hospital emergency services (WCSHES). Teams working in these emergency services experience a heavy workload and have a limited amount of time with each patient. COVID-19 has further complicated these existing issues. Therefore, we believed it would be helpful to draft an abridged version of the 40-item WCSHES, considering both validity and reliability criteria, but giving greater weight to validity. One hundred and twenty-six workers between the ages of 20 to 64 (M = 32.45; standard deviation (SD = 9.73)) years old participated voluntarily in the study. The validity, reliability, and fit model were evaluated in an iterative process. The confirmatory factor analysis yielded appropriate global fit indices in the abridged 24-item version (Χ²(248) = 367.84; p < 0.01, RMSEA = 0.06 with an interval of 90% from 0.05 to 0.07, SRMR = 0.08, GFI = 0.9, AGFI = 0.96, CFI = 0.98, NFI = 0.95, and NNFI = 0.98), along with test criteria validity (ρ_XY = 0.68, p < 0.001) and excellent reliability (α = 0.94 and ω = 0.94), maintaining the same conceptualization and usefulness of the original scale. The abridged 24-item version was used to measure four work climate factors (work satisfaction, productivity/achievement of aims, interpersonal relations, and performance at work). Evidence of the usefulness of the new abridged scale is provided along with a description of our study limitations and future areas for development.
