Current Trends in Nursing II

1.4K
Trends in nursing are multifactorial and associated with changes in society, within the nursing profession, and in other professions. Notably, telehealth and remote nursing contribute to successful healthcare delivery for numerous patients and help reduce stress for nurses due to nursing shortages. Nurses can reach patients, monitor their conditions, and interact with them using computers, audio, visual accessories, and telephones—for example, remote patient monitoring systems. Likewise,...

Issues And Trends In Healthcare Delivery System

5.9K
The issues and trends in healthcare delivery are constantly changing. The COVID-19 pandemic is one recent issue that wreaked havoc on healthcare systems, causing a shortage of healthcare workers, high demand for medicines and supplies, and increased medical expenditure due to a lack of insurance. Other issues include rising healthcare costs and care fragmentation.
Cost Containment
Payment for healthcare services has historically promoted adoption of costly and often unnecessary or inefficient...

Glaucoma: Overview01:25

Glaucoma: Overview

940
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...

Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

866
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...

Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

733
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.
Drugs such as carbonic anhydrase inhibitors, α2- and...

Area of Science:

  • Ophthalmology and Optometry
  • Contact Lens Technology
  • Public Health & Epidemiology

Background:

  • Contact lens prescribing data are crucial for eye care professionals, researchers, and the contact lens industry.
  • Understanding prescribing patterns helps benchmark clinical practice and identify trends.

Purpose of the Study:

  • To document global trends in contact lens prescribing from 1996 to 2020.
  • To analyze changes in lens types, wearer demographics, and fitting practices over two decades.

Main Methods:

  • A longitudinal survey collected data on contact lens fits from practitioners worldwide.
  • Information from 406,859 contact lens fits across 71 countries (1996-2020) was analyzed.
  • Trend analysis focused on 20 countries with at least 13 years of data (2000-2020).

Main Results:

  • Majority of lenses (65-70%) fitted to females; average wearer age increased.
  • Significant rise in silicone hydrogel and daily disposable lens fitting.
  • Increased fitting of toric and multifocal lenses; specialist rigid lens designs grew.
  • Near correction provision for presbyopes remained incomplete; extended wear remained low.
  • Multi-purpose care systems dominated; daily disposables used for all wear durations.

Conclusions:

  • International contact lens fitting practices evolved considerably between 2000 and 2020.
  • Findings can inform clinical practice, research, and product development in the contact lens field.
  • Data highlights shifts towards advanced lens materials and designs, and changing wearer demographics.
