The Cost Effectiveness of Mental Health Treatment in the Lifetime of Older Adults with HIV in New York City: A Markov Approach

Evaluating the cost-effectiveness of a pre-exposure prophylaxis program for HIV prevention for men who have sex with men in Japan

Men who have sex with men (MSM) have been disproportionally affected by the HIV epidemic in many countries, including Japan. Although pre-exposure prophylaxis (PrEP) is a strong prevention tool, it is not yet approved in Japan. A Markov model was developed to describe HIV infection and disease progression in an MSM cohort (N = 1000) in Japan receiving a PrEP program. The model was used to evaluate the cost-effectiveness of a PrEP program. HIV/AIDS treatment, screening, hospitalization due to AIDS, and PrEP were considered as costs and quality-adjusted life-years (QALYs) gained as utilities. Cost-effectiveness was assessed by comparing the incremental cost-effectiveness ratio (ICER) over a 30-year period against the willingness to pay (WTP) threshold. One-way sensitivity and probabilistic sensitivity analyses were performed. With 50% PrEP coverage, the PrEP program became dominant against the program without PrEP, using a threshold of 5.0 million JPY/QALY (45,455 USD). The probabilistic sensitivity analysis revealed that the PrEP program was dominant or at least cost-effective in most cases of 10,000 simulations. Therefore, preparing cheaper PrEP pills, which results in PrEP being dominant or ICER being lower than the WTP threshold, is important to make the program cost-effective. Introduction of PrEP to an MSM cohort in Japan would be cost-effective over a 30-year time horizon.

COVID-19, Race/Ethnicity, and Age: the Role of Telemedicine to Close the Gaps on Health Disparities

The novel COVID-19 outbreak is a major public health challenge that quickly turned into an economic recession of great proportions. This pandemic poses a trade-off between health and the economy where social distancing, quarantines, and isolation shut down demand and supply chains across the USA. This paper analyzes the impact of COVID-19 on illness and death among older adults and communities of color with low socioeconomic status in New York City. To achieve this goal, fractional logit models are used to capture changes in the novel virus’ morbidity and mortality rates at the neighborhood level. Median income, race/ethnicity, age, household crowding, and socially interactive employment explained the disproportionate exposure and fatalities across the city. We also employ a variable related to telehealth/telemedicine to sustain that technology goods along with government intervention as a provider of social goods can ameliorate existing health disparities. There is a need for evidence-based data on the economic costs and social benefits of COVID-19 relief programs.

Cost-Effectiveness Analysis Combining Medical and Mental Health Services for Older Adults with HIV in New York City

Older adults with the human immunodeficiency virus or HIV (OAWH), people 50 years and older, are aging with the disease and experience low quality of life. Mental health disorders trigger and worsen health inequalities with larger impacts on the quality of life of OAWH. This paper evaluated two rival health interventions using a standard decision-analytic model and quantified the cost per quality-adjusted life-years (QALY) to understand the differential in cost and effectiveness of an additional unit of perfect health. HIV medical care was compared with a combined strategy that includes both HIV medical and behavioral care. Primary data from a convenience sample (n=139) collected in New York City and outcomes for healthy older adults from the literature were used in this study. The incremental cost-effectiveness ratio (ICER) evaluating the economic cost and health benefits of the new intervention was $36,166 per QALY, which is less than the willingness to pay ($75,000). The ICER for Hispanics was $35,325 and for White/Caucasians was $40,499. Integrated medical plus behavioral care is cost-effective and improves quality of life among OAWH. Given the high rates of mental health disorders along with an underutilization of behavioral care among OAWH, timely and effective mental health programs are paramount to increase quality of life.

Modelling the Economic Impact of Reducing Loneliness in Community Dwelling Older People in England

Loneliness has been associated with poor mental health and wellbeing. In England, a 2018 national strategy on loneliness was published, and public health guidelines recommend participation in social activities. In the absence of existing economic evidence, we modelled the potential cost effectiveness of a service that connects lonely older people to social activities against no-intervention. A 5-year Markov model was constructed from a health and social care perspective. Parameters were drawn from the literature, with the intervention structure based on an existing loneliness alleviation programme implemented in several settings across England. Univariate and probabilistic sensitivity analyses were undertaken. The total expected cost per participant in the intervention group is £ 7131 compared to £ 6783 in the usual care group with 0.45 loneliness free years (LFY) gained. The incremental cost per LFY gained is £ 768; in the probabilistic sensitivity analysis the intervention is cost saving in 3.5% of iterations. Potentially such interventions may be cost-effective but are unlikely to be cost-saving even allowing for sustained effects and cumulative adverse health and social care events averted. Empirical studies are needed to determine the cost-effectiveness of these interventions, ideally mapping changes in loneliness to the quality of life, in order to allow the key metric in health economic studies, cost per quality adjusted life year to be estimated.
