Knowledge, attitudes and practices regarding iodine among patients with hyperthyroidism in the Free State, South Africa

Objectives: To gather baseline information on the knowledge, attitudes and practices regarding iodine and iodised salt among patients with hyperthyroidism in the Free State.Subjects and Setting: The study was part of a large cohort study that included the first 96 patients aged 13 years or older diagnosed with hyperthyroidism and referred to Universitas Academic Hospital in Bloemfontein, South Africa during 2005.Methods: The patients were interviewed in their language using a structured validated questionnaire. Descriptive statistics were used fordata analysis.Results: The majority of the patients (86.9%) did not know what iodine was. Similarly, a higher percentage of patients (76.7%) were unaware of the most important or main source of iodine in the food of South Africans. Regarding knowledge of the most important harmful effect on the health of children if they did not get enough iodine, almost all of the patients (89.1%) did not know what it was. Ninety-five per cent of salt was obtained from the local shops, and only 36.1% of the patients read the labelling on the package during purchase. A very small proportion of patients (1.6%) stored salt in closed containers and away from sunlight, while about half of them (49.2%) stored salt in open containers without lids, 36.1% stored it in rigid plastic containers with holes at the top, and 13.1% stored it in the open plastic bags in which the salt was bought.Conclusions: Patients with hyperthyroidism lacked knowledge of iodine, as well as of the storage of iodised salt, and this could have contributed to the persisting endemic goitre reported in previous studies. An aggressive awareness programme, targeting policy makers and the public, is recommended to ensure sustainable elimination of iodine deficiency disorders in South Africa.  Keywords: hyperthyroidism; iodine; iodised salt; knowledge-attitude-practice study; South Afric

A population-based study of ambulatory and surgical services provided by orthopaedic surgeons for musculoskeletal conditions

<p>Abstract</p> <p>Background</p> <p>The ongoing process of population aging is associated with an increase in prevalence of musculoskeletal conditions with a concomitant increase in the demand of orthopaedic services. Shortages of orthopaedic services have been documented in Canada and elsewhere. This population-based study describes the number of patients seen by orthopaedic surgeons in office and hospital settings to set the scene for the development of strategies that could maximize the availability of orthopaedic resources.</p> <p>Methods</p> <p>Administrative data from the Ontario Health Insurance Plan and Canadian Institute for Health Information hospital separation databases for the 2005/06 fiscal year were used to identify individuals accessing orthopaedic services in Ontario, Canada. The number of patients with encounters with orthopaedic surgeons, the number of encounters and the number of surgeries carried out by orthopaedic surgeons were estimated according to condition groups, service location, patient's age and sex.</p> <p>Results</p> <p>In 2005/06, over 520,000 Ontarians (41 per 1,000 population) had over 1.3 million encounters with orthopaedic surgeons. Of those 86% were ambulatory encounters and 14% were in hospital encounters. The majority of ambulatory encounters were for an injury or related condition (44%) followed by arthritis and related conditions (37%). Osteoarthritis accounted for 16% of all ambulatory encounters. Orthopaedic surgeons carried out over 140,000 surgeries in 2005/06: joint replacement accounted for 25% of all orthopaedic surgeries, whereas closed repair accounted for 16% and reductions accounted for 21%. Half of the orthopaedic surgeries were for arthritis and related conditions.</p> <p>Conclusion</p> <p>The large volume of ambulatory care points to the significant contribution of orthopaedic surgeons to the medical management of chronic musculoskeletal conditions including arthritis and injuries. The findings highlight that surgery is only one component of the work of orthopaedic surgeons in the management of these conditions. Policy makers and orthopaedic surgeons need to be creative in developing strategies to accommodate the growing workload of orthopaedic surgeons without sacrificing quality of care of patients with musculoskeletal conditions.</p
