Using multiple care models to treat patients with HIV may be slightly more effective than using a single model, study data show.

Researchers also reported that differences among all care delivery models in the study were small, and equaled or outperformed previous quality indicator rates.

“The HIV/AIDS epidemic has transitioned over the past two decades, from a focus on treatment of opportunistic infections and management of complex ART regimens to a chronic disease model for care of patients with near-normal life expectancy and an increased focus on noncommunicable disease prevention and management while maintaining high quality HIV care,” Corinne M. Rhodes, MD, MPH, of the division of general internal medicine at the University of Pennsylvania, Philadelphia, and colleagues wrote. “There are multiple approaches to provide HIV care that include HIV and primary care provided by infectious disease specialist alone, by generalist alone or by a combination model where HIV care is provided by ID specialist and primary care is provided by a generalist. There are no formal recommendations for preferred HIV care model.”

The researchers organized 1,565 patients with HIV into three care groups: generalist, ID provider and ID provider plus generalist. Rhodes and colleagues then created four categories of quality-of-care indicators: HIV management, immunization, screening and process.

Most patients fell under the ID group (n = 875), with 90 in the generalist group and 675 in the combined group. Researchers noted different racial, ethnic and socioeconomic demographic makeups among each group. The ID group had a higher proportion of white, male English-speaking patients, while the ID plus generalist group had larger proportions of black patients, a higher number of clinic visits in 2012 and a higher proportion of patients with high Charlson scores. The generalist group contained a higher proportion of patients earning below the statewide median income and more Hispanic and non-English speaking patients.

The ID group had a retention rate of 96%, compared with 99.3% in the ID plus generalist group and 100% in the generalist group. Multivariable adjusted analysis showed the ID plus generalist group outperformed the ID group in HIV management (94.4% vs. 91.7%; P = .03), and had higher quality measures than the generalist group for immunization (87.8% vs. 80.6%; P = .03), Rhodes and colleagues reported. The absolute differences between individual groups ranged from 2% to 7%, prompting the researchers to suggest that the results should be taken in the context of physician or patient preference as well as cost and use.

“In conclusion, we found minimal differences in HIV quality metrics between HIV care models, with performance across groups surpassing previous results reported in the literature,” Rhodes and colleagues wrote. “Whether these differences translate into improved morbidity or mortality remains unknown. Our results suggest many models of HIV care are effective for HIV-related screening and management and that health care system, feasibility and patient and physician preference may guide HIV care model selections.” – by Andy Polhamus
