Martin-Iguacel R, et al. - In this study, researchers analyzed data from national registries to quantify the fraction of people with a diagnosis of HIV who had primary health care (PHC) contacts 3 years earlier to diagnosis in a cohort of 2,784 patients and 36,192 control participants. They also examined the relation of the risk of HIV diagnosis and degree of immunodeficiency with the frequency of visits or procedures performed. With a higher median number of visits to PHC (NVPC) for patients, they noted that 93% of patients and 88% of controls attended PHC at least once in the 3 years preceding diagnosis. In males and non-Danish women, they found a statistically significant positive correlation between NVPC and risk of consequent HIV diagnosis. But they did not observe a firm relationship between NVPC and degree of immunodeficiency. A weak link was noted between the risk of HIV diagnosis and degree of immunodeficiency and the type of procedures performed.
