Systematic Review of Comparisons Between Plastic and Silicone Dilators: Revealing a Knowledge Gap

INTRODUCTION

Vaginal stenosis is a distressing side effect of radiation therapy that can impair quality of life. Dilator therapy is an option for patients undergoing pelvic radiotherapy to mitigate vaginal stenosis. Currently, the dilators given to patients by most hospitals are made of plastic, compared to silicone dilators which are available on the market for purchase.

OBJECTIVES

We conducted a systematic literature review to find information to guide clinical recommendations to pelvic radiotherapy patients on potential differences regarding the use of plastic vs silicone dilators with regard to efficacy, cost, and patient preferences.

METHODS

A systematic literature review was conducted in Embase, MEDLINE, and PubMed using Emtree terms. To be included in the review, papers needed to: focus on female patients undergoing radiation therapy, assess a vaginal dilator, measure any dilator intervention outcome, and specifically compare plastic vs silicone dilators for any measured outcome (either qualitative or quantitative).

RESULTS

The initial search yielded 195 articles. Two area experts, with a third expert for arbitration, read each article and found that none met all review inclusion criteria. No studies were found that compared silicone to plastic dilators with regard to efficacy in treating vaginal stenosis due to radiation therapy, no studies were found that compared cost or cost-effectiveness of the 2 dilator types, and no studies were found comparing patient preferences or experiences (eg, comfort, adherence, ease of use) between the 2 dilator types.

CONCLUSION

The materials used to create dilators have never been rigorously compared in the context of radiotherapy-related vaginal stenosis. Institutions and patients have no data to guide their choice. Significantly more research at the patient and institutional level is needed to explore the potential long-term quality of life and cost benefits of improved adherence with silicone dilator use, and to guide shared decision-making regarding dilator choice.

The health behaviors of the older US worker

BACKGROUND

As the US workforce ages, lifestyle factors will increasingly affect their health, yet little information is available on their prevalence in older working populations.

METHODS

Using the nationally representative 1997-2003 National Health Interview Survey (NHIS), reported current smoking, risky drinking and leisure-time physical activity behaviors of older workers (> or =65 years) were compared with older non-workers. These behaviors were evaluated by age, gender, race, ethnicity, and occupation, as well as prototype "healthy" and "risky" persons.

RESULTS

The study population of 4,946 older US workers and 38,313 older non-workers represented an estimated 3.9 million older workers and 28.9 million older non-workers annually. Relative to older non-workers, older workers reported more current smoking and risky drinking, but higher levels of leisure-time physical activity with variations by subpopulations.

CONCLUSIONS

Less than 4% of the older US worker population reported overall healthy behaviors. Certain occupations and other subpopulations can be targeted for age-appropriate behavioral interventions.
