Objective: To assess the use, effectiveness and acceptance of prescribed contraception in three remote Western Australian Aboriginal communities.
Participants And Design: Mixed method study, including retrospective file review of contraception methods for 566 regular female Aboriginal patients, 1 November 2010 - 1 September 2014, and semi-structured interviews with 20 Aboriginal women.
Setting: Primary care clinics in three remote Aboriginal communities.
Main Outcome Measures: Number of episodes of contraceptive use, effectiveness and continuation rates of prescribed contraceptive use; personal experiences, attitudes towards and beliefs about contraception options.
Results: 34% of women had used contraception, ranging from 15% of women aged younger than 15 years to 55% of women aged 15-19 years. The most common forms of contraception at the census date were long-acting reversible contraceptives (LARCs): 77% of women using contraception had an etonogestrel implant and 7% had depot medroxyprogesterone. Etonogestrel continuation rates at 1, 2 and 3 years were 87% (95% CI, 81-92%), 72% (95% CI, 64-78%) and 51% (95% CI, 41-60%) respectively. Medroxyprogesterone depot continuation at one year was only 14% (95% CI, 8-22%). Social acceptance of the etonogestrel implant was high; no concerns were raised about stigma or unwanted attention related to implant use.
Conclusion: The high uptake of LARCs in these communities is consistent with international recommendations about contraception use. High acceptability was reflected in excellent continuation rates. Service delivery models that use community engagement and capacity building are recommended for broadening the focus of sexual health beyond sexually transmitted disease detection and management, giving priority to the reproductive rights and unmet needs of Aboriginal women.
Internet of Things (IoT) is changing patient engagement in healthcare by shifting from traditional care models to a continuous, technology-driven approach using IoT-based Remote Monitoring Systems (IoT-RMS). This research seeks to redefine patient engagement by examining how Internet of Things (IoT) technologies can impact healthcare management and patient-provider interactions at different phases. Additionally, it presents the relationship between patient engagement stages and IoT-RMS, which promotes patients' active participation using technological health management tools.
This paper investigates the evolution of changes in surface ultraviolet (UV) radiation globally, emphasizing the significant impacts of key factors influencing its variability, i.e., total column ozone, aerosols, clouds, and surface reflectivity.
The integration of psychiatric treatment into emergency services is critical to improving the management of severe mental health emergencies. Emergency departments (EDs) are frequently the initial point of contact for patients with mental emergencies, but they are not always prepared to offer adequate care. This systematic review aims to analyze the effectiveness of collaborative care models (CCMs), psychiatric consultation-liaison (C-L) teams, and telepsychiatry in enhancing psychiatric treatment in emergencies.
Telemedicine in surgical care has undergone rapid advancements in recent years, leveraging technologies such as telerobotics, artificial intelligence (AI) diagnostics, and wearable devices to facilitate remote evaluation and monitoring of patients. These innovations have improved access to care, reduced costs, and enhanced patient satisfaction. However, significant challenges remain, including technical barriers, limited tactile feedback in telesurgery, and inequities arising from digital literacy and infrastructure gaps.
Unlabelled: Holography is an essential technique of generating three-dimensional images. Recently, quantum holography with undetected photons (QHUP) has emerged as a groundbreaking method capable of capturing complex amplitude images. Despite its potential, the practical application of QHUP has been limited by susceptibility to phase disturbances, low interference visibility, and limited spatial resolution.
