Summary
A community vision care program significantly reduced distance visual impairment (VI) in elderly individuals. Corrective lenses effectively lowered VI prevalence, demonstrating the program
Area of Science:
- Ophthalmology
- Public Health
- Gerontology
Background:
- Elderly populations face a high prevalence of distance visual impairment (VI).
- Community-based vision care programs offer a potential solution for managing VI in older adults.
Purpose of the Study:
- To evaluate the real-world effectiveness of a community vision care program for individuals aged 60 and above.
- To assess the cost-effectiveness of the program from a funder's perspective.
Main Methods:
- Analysis of data from 8899 elderly subjects participating in a vision care program (2015-2019).
- Evaluation of distance visual impairment (VI) prevalence before and after refractive error correction.
- Estimation of cost per distance VI case avoided.
Main Results:
- Presenting distance VI prevalence was 39.1% (worse eye) and 17.3% (better eye).
- After correction, VI prevalence reduced to 13.8% (worse eye) and 4.2% (better eye).
- Uncorrected refractive error was the primary cause of presenting VI; cost per VI case prevented ranged from HK$1921 to HK$3715.
Conclusions:
- Community vision programs can significantly decrease distance VI in the elderly.
- Effective optical correction is crucial for reducing avoidable VI in older populations.
- Such programs offer individual and societal benefits by minimizing vision impairment.

Community-based interventions in mental health represent a paradigm shift from institution-centered care to treatments embedded within the fabric of local communities. By prioritizing inclusion and leveraging existing societal structures, this approach fosters a supportive environment conducive to addressing mental health challenges while promoting individual dignity and agency.

The evaluation stage signals the end of the nursing process. The nurse gathers evaluative data to assess whether or not the patient has attained the expected results. Whereas the nurse collects data in the nursing assessment to identify the patient's health concerns, the evaluation stage data determines if the indicated health issues are resolved. Evaluative data collection includes two sections: the data acquired to evaluate patient outcomes and the time criteria for data collection.

Continuing care describes the variety of health, personal, and social services provided over a prolonged period. The need for continuing care is increasing because people are living longer. Many people do not have families or others to care for them. Continuing care is mainly for patients who are disabled, functionally dependent, or suffering from a terminal disease. It is available within institutional settings or in homes. Examples include nursing centers or facilities, assisted living,...

Rural Health Centers
Rural health centers are specialized care facilities in remote locations with very few medical personnel. The primary care providers who run the centers are mostly Registered Nurse Practitioners. Here, emergency treatment is provided to critically ill or injured patients before they are transferred to the closest hospital. Fortunately, due to advancement in technology, many rural healthcare facilities and professionals have easy access to diagnostic and treatment...

At the different levels of the healthcare system, we see varying methods of healthcare used. These methods include managed care systems, case management, and primary healthcare.
Managed Care System:
The managed care system is designed to control the cost while maintaining the quality of care. The patient's care from admission to discharge is planned by the primary care provider or the case manager, also known as the gatekeeper. In a managed care system, the number of care providers is...
