Prevalence and determinants of insufficient work ability in older HIV-positive and HIV-negative workers

Predicting occupational outcomes from neuropsychological test performance in older people with HIV

OBJECTIVE

The ability to work is amongst the top concerns of people living with well treated HIV. Cognitive impairment has been reported in many otherwise asymptomatic persons living with HIV and even mild impairment is associated with higher rates of occupational difficulties. There are several classification algorithms for HIV-associated neurocognitive disorder (HAND) as well as overall scoring methods available to summarize neuropsychological performance. We asked which method best explained work status and productivity.

DESIGN

Participants (N = 263) drawn from a longitudinal Canadian cohort underwent neuropsychological testing.

METHODS

: Several classification algorithms were applied to establish a HAND diagnosis and two summary measures (NPZ and Global Deficit Score) were computed. Self-reported work status and productivity was assessed at each study visit (four visits, 9 months apart). The association of work status with each diagnostic classification and summary measure was estimated using logistic regression. For those working, the value on the productivity scale was regressed within individuals over time, and the slopes were regressed on each neuropsychological outcome.

RESULTS

The application of different classification algorithms to the neuropsychological data resulted in rates of impairment that ranged from 28.5 to 78.7%. Being classified as impaired by any method was associated with a higher rate of unemployment. None of the diagnostic classifications or summary methods predicted productivity, at time of testing or over the following 36 months.

CONCLUSION

Neuropsychological diagnostic classifications and summary scores identified participants who were more likely to be unemployed, but none explained productivity. New methods of assessing cognition are required to inform optimal workforce engagement.

Workability of patients with HIV/AIDS in Northern Vietnam: a societal perspective on the impact of treatment program

In Vietnam, the antiretroviral therapy (ART) program has been widely scaled up across the country since 2005, and now covers treatment for about half the HIV population. However, limited data exist about the workability and productivity outcome of ART in Vietnam. We aim to assess the employment status and work productivity among HIV patients taking ART in Northern Vietnam. A cross-sectional study was conducted in Hanoi and Nam Dinh with 1133 participants taking ART at the selected clinics. The Work Productivity and Activity Impairment Questionnaire: General Health (WPAI-GH) was applied. We found that 23% of patients with HIV/AIDS reported overall work productivity loss, and 12% had activity impairment. Among those having a job, their monthly income, however, was significantly lower than national averages 2806 thousand VND vs. 4120 thousand VND). The average education level of participants was low, with only 41.61% having greater than secondary education. Health problems and lower CD4 cell counts decreased workability of the patients while having a more dependent family, being a smoker or having a later HIV stage was associated with being less likely to have a job. The rate of employment among HIV/AIDS patients in this study was high however incomes were substantially lower than average. This could be due to low education levels or social stigma regarding these patients. Vocational education programs and public awareness could empower the patients economically. Similarly, a number of social and behavioral problems were associated with decreasing the working rate and productivity. Addressing these health issues may improve productivity among patients.
