In Search of a Value Proposition for COVID-19 Testing in the Work Environment: A Social Marketing Analysis

BACKGROUND

This study examined employer experience with SARS-CoV-2 (COVID-19) asymptomatic testing through a social marketing lens. Social marketing uses commercial marketing principles to achieve socially beneficial ends including improved health and safety behavior.

METHOD

Twenty employers across 11 occupational sectors were interviewed about implementation of COVID-19 testing from January through April 2021. Recorded transcripts were coded and analyzed using marketing's "Four P's": "product," "price," "place," "promotion."

RESULTS

COVID-19 tests (product) were uncomfortable, were easily confused, and didn't solve problems articulated by employers. Testing was not widely available or didn't line up with shifts or locations (place). The perceived price, which included direct and associated costs (e.g., laboratory fees, productivity loss, logistical challenges) was high. Most crucially, the time to receive (PCR) results negated the major benefit of less time spent in quarantine and challenged employer trust. A potential audience segmentation strategy based on perceptions of exposure risk also emerged.

CONCLUSIONS

This social marketing analysis suggests ways to improve the value proposition for asymptomatic testing through changes in product, price, and placement features in line with employers' expressed needs. Study findings can also inform creation of employee communication materials that balance perceived rewards of testing against perceived risks of exposure.

Subclinical nephrotoxicity caused by smoking and occupational silica exposure among Egyptian industrial workers

BACKGROUND

The aim of the present work was to investigate early signs of subclinical renal alterations due to silica exposure and smoking among non-silicotics and silicotics by measuring urinary indicators of nephrotoxicity.

METHODS

The subjects comprised 29 non-silicotics (9 non-smokers, 20 smokers), 24 silicotics (9 non-smokers, 15 smokers), and 28 referents (9 non-smokers, 19 smokers). Measured urinary parameters were concentrations of total protein, microalbumin, retinol-binding protein, and activities of N-acetyl-beta-D-glucosaminidase and glutathione S-transferase. In addition, we measured levels of urinary silicon and creatinine.

RESULTS

Compared with referents, both non-silicotics and silicotics excreted significant high levels of all measured parameters. Smokers in each investigated group also showed increased levels (although not significant) of renal parameters in comparison to corresponding non-smokers. Among non-silicotics, the present results showed that elevation of measured urinary parameters was significantly associated with work duration, while only urinary excretion of glutathione S-transferase was associated with work duration among silicotics.

CONCLUSIONS

The study confirms that silica may lead to subclinical signs of nephrotoxicity, and that smoking also has a nephrotoxic effect on kidney and is synergistic to nephrotoxicity of silica exposure. Additionally, the study suggests that renal alterations may occur prior to pulmonary involvement.
