Purpose In the Indonesian health‐care system, nurses and midwives often serve as the primary health‐care providers due to physician shortages. Seeking to address the need for medical care in resource‐limited environments, some have advocated for portable equipment in the hands of health‐care providers. We hypothesized that medical students are able to effectively teach point‐of‐care ultrasound (POCUS) to physicians, nurses, and midwives in rural Indonesia. Methods We conducted a prospective, observational study using health‐care practitioners from a clinic and accredited school for nursing and midwifery in Mojokerto, East Java, Indonesia. Enrolled practitioners took part in a 4‐week POCUS course followed by postinstructional testing. Results A total of 55 health‐care practitioners completed the course. This included 19 physicians, 13 nurses, and 19 midwives. Of the 55 clinicians, 43 (72%) passed the course and 12 (28%) failed. Conclusions Physicians, nurses, and midwives in rural Indonesia showed significant acquisition of ultrasound (US) knowledge and skills following a 4‐week US course. Following training, all three groups displayed skills in practical US use during a postcourse practical examination. This is one of the first studies to assess the efficacy of medical students teaching POCUS to midwives and nurses.

Introduction: Encrustation of implanted urinary tract devices is associated with significant morbidity. Pellethane Ò is a polyether-based compound noted for its strength, porosity, and resistance to solvents. We assessed Pellethane thermoplastic polyurethane (TPU) with and without surface coatings 2-hydroxyethyl methacrylate (HEMA) and tetraethylene glycol dimethyl ether (TETRA) for the potential to resist encrustation in an artificial urine environment. Materials and Methods: Samples of Pellethane TPU, HEMA Pellethane TPU, TETRA Pellethane TPU, and hydrogel-coated ureteral stent (Cook Ò) were suspended in a batch-flow model with an artificial urine solution (AUS). Every 48 hours for 90 days, 40% of the solution was replaced with fresh AUS. All samples were stored in a 37°C incubator. Subsequently, the samples were thoroughly dried for 48 hours before weighing. Scanning electron microscopy was used to assess the degree of encrustation. Nu-Attom Inductively Coupled Plasma Mass Spectrometry (ICP-MS) was used to determine the precise compositions of the encrustation specifically with regard to calcium, magnesium, and phosphate. Results: At the conclusion of the 90-day trial, the samples were analyzed, and the average mass changes were as follows: stent 63.78%, uncoated Pellethane TPU 11.50%, HEMA-coated Pellethane TPU 2.90%, and TETRAcoated Pellethane TPU 0.60%. Pellethane TPU products, and specifically those coated with HEMA and TETRA, exhibited less average mass increase and a lesser propensity to form encrustation than the traditional urinary tract stent. The mass increases noted on coated Pellethane devices were primarily ionic, whereas that of the stent was not. Conclusion: Pellethane, particularly with an HEMA-based preventative coating, may serve as a favorable alternative to traditional urinary stent material, providing its improved resistance to encrustation.
