Which patients wait longer to be seen and when? A waiting time study in the emergency department

We investigated the waiting time for patients before seeing a physician in the emergency department of a tertiary care hospital in Riyadh, Saudi Arabia. Bi- and multivariate analyses of routine data for 2187 patients determined the association between selected patient characteristics and waiting time. The median waiting time between triage and being seen by a physician was 35.0 min [range 1.0-325.0 min]. Age, day of arrival, time of arrival and triage category were significantly associated with waiting time. Older patients and those arriving on Sundays and Wednesdays waited longer. Variability in waiting times could be addressed by more standardized triage policies, but may also be influenced by other clinical or non-clinical factors that require further investigation

Dietary fat and breast cancer in Saudi Arabia: a case-control study

A case-control study investigated the association between dietary fat and breast cancer in Saudi Arabian women attending a specialist hospital in Riyadh. Women with breast carcinoma [n= 499] newly diagnosed between 1996-2002, and control women [n = 498] randomly selected from patients' attendants and relatives, completed a food frequency questionnaire. Serum levels of triglycerides and total cholesterol were measured. A significant positive association was found between risk of breast cancer and intake of fats, protein and calories. Adjusted odds ratios for the highest quartile of intake versus the lowest were 2.43 for saturated fat, 2.25 for animal protein, 2.12 for polyunsaturated fat, 1.88 for cholesterol and 2.69 for total energy from dietary intake. For serum triglycerides the adjusted odds ratio was 2.16 for the highest quartile
