Intravenous iron therapy in a rural hospital: A retrospective chart review.

INTRODUCTION: Intravenous iron infusion therapy is commonly delivered in rural hospitals, but there are no common guidelines for dosing or choice of agent. The objective of the study was to understand present practice and alternate therapies and develop practical recommendations for small hospital use. METHODS: This was a retrospective chart review of all non-dialysis patients aged 15 years or older who received iron replacement therapy at Sioux Lookout Meno Ya Win Health Centre from May 2013 to May 2019 and a literature review of available iron preparations. RESULTS: Of the 147 patients who received intravenous iron replacement, 75 were administered a single dose of 200 mg or 500 mg iron sucrose. Commonly used in pregnant patients, an increase in haemoglobin by an average of 9.2 g/L followed a 200 mg dose and 12.5 g/L after 500 mg. The 3-h infusion time for the 500 mg dose consumed considerably more nursing resources. Non-pregnant patients can be transfused more effectively with iron maltoside which can efficiently deliver larger doses of iron. CONCLUSION: We recommend iron maltoside for efficient intravenous iron replacement in non-pregnant patients and single or multiple doses of 200 mg iron sucrose during pregnancy.

Résumé Introduction: La perfusion intraveineuse de fer est fréquente dans les hôpitaux ruraux, mais il n'existe pas de lignes directrices courantes sur la posologie ou le choix de l'agent. Cette étude visait à comprendre la pratique actuelle, et les autres options thérapeutiques et d'émettre des recommandations pratiques à l'intention des petits hôpitaux. Méthodologie: Revue rétrospective des dossiers de tous les patients de 15 ans et plus non sous dialyse qui avaient reçu une supplémentation en fer à l'Hôpital SLMHC entre les mois de mai 2013 et mai 2019 et revue de la littérature sur les préparations de fer commercialisées. Résultats: Sur les 147 patients ayant reçu une perfusion de supplémentation en fer, 75 ont reçu une dose unique de 200 mg ou de 500 mg de fer-saccharose. Fréquemment utilisées chez les femmes enceintes, les doses de 200 et de 500 mg ont augmenté le taux d'Hb d'en moyenne 9,2 g/L et de 12.5 g/L, respectivement. La perfusion de 3 heures nécessaire à la dose de 500 mg a utilisé considérablement plus de ressources infirmières. Le fer-isomaltoside, qui administre efficacement des doses supérieures de fer, est perfusé plus efficacement chez les patients, à l'exclusion des femmes enceintes. Conclusion: Nous recommandons le fer-isomaltoside pour la supplémentation en fer efficace chez les patients, à l'exclusion des femmes enceintes et une dose unique ou multiple de 200 mg de fer-saccharose durant la grossesse. Mots-clés: Fer-isomaltoside, médecine rurale, perfusion intraveineuse de fer.

Factors that influence soft tissue thickness over the greater trochanter: application to understanding hip fractures.

Fall-related hip injuries are a concern for the growing population of older adults. Evidence suggests that soft tissue overlying the greater trochanter attenuates the forces transmitted to the proximal femur during an impact, reducing mechanical risk of hip fracture. However, there is limited information about the factors that influence trochanteric soft tissue thickness. The current study used ultrasonography and electromyography to determine whether trochanteric soft tissue thickness could be quantified reproducibly and whether it was influenced by: (1) gender; (2) hip postures associated with potential falling configurations in the sagittal plane (from 30° of extension to 60° of flexion, at 15° intervals), combined adduction-flexion, and combined adduction-extension; and (3) activation levels of the tensor fascia lata (TFL) and gluteus medius (GM) muscles. Our results demonstrated that soft tissue thickness can be measured reliably in nine hip postures and three muscle activation conditions (for all conditions, ICC >0.98). Mean (SD) thickness in quiet stance was 2.52 cm. Thickness was 27.0% lower for males than females during quiet stance. It was 16.4% greater at maximum flexion than quiet standing, 27.2% greater at maximum extension, and 12.5% greater during combined adduction-flexion. However, there was no significant difference between combined adduction-extension and quiet standing. Thickness was not affected by changes in muscle activity. Forces applied to the femoral neck during a lateral fall decrease as trochanteric soft tissue thickness increases; gender and postural configuration at impact could influence the loads applied to the proximal femur (and thus hip fracture risk) during falls on the hip.

Epidural steroid injections for low back pain in rural practice: a 5-year retrospective study.

INTRODUCTION: Epidural steroid injections (ESIs) are a safe and accessible therapy for chronic low back pain, one of the most common and challenging chronic conditions seen in primary care. However, the indications for and effectiveness of ESI remain controversial. In rural settings with limited public transportation infrastructure, such a mobility-limiting condition can have even more negative effects on quality of life and function. Furthermore, diagnostic and specialist services are often limited. A paucity of safe, effective and accessible treatments leads to heavy reliance on oral analgesics, especially opioids, which have well-known complications. METHODS: We reviewed the use of ESI for the 2 most common types of chronic low back pain in those with neurologic symptoms: lumbar disc herniation (LDH) and lumbar spinal stenosis (LSS). We did a retrospective chart review of all patients who underwent ESI between Jan. 1, 2005, and Feb. 25, 2010, at our rural hospital in northwestern Ontario. RESULTS: During the study period, 123 ESIs were administered to 65 patients. After the first injection, 40 patients (62%) reported improvement, 10 (15%) reported worsening or no change, and 15 (23%) had no follow-up documented. CONCLUSION: Some patients with neurologic compromise from LDH or LSS have improvement in symptoms after ESI. A prospective study is underway to more rigorously assess the effectiveness of this treatment.
