Predictors of Post Operative Morbidity in Older Women With Pelvic Organ Prolapse

An increasing number of elderly women are undergoing surgical treatment for pelvic organ prolapse (POP). Based on US Census data1 and the estimated prevalence of pelvic organ prolapse in women 60 and over, an estimated 1.6 million women over 60 are currently affected with pelvic organ prolapse (POP). This number is expected to increase to 3.4 million by 2050. Prior studies show that geriatric patients have unique physiologic vulnerability, and elderly women undergoing surgery are at risk for worse post-operative outcomes than younger women. However, data from the urogynecology literature are conflicting. Some studies show an increased risk for complications as women age while other studies show no significant increased risk. Other evidence suggests that elderly women still are below their baseline quality-of-life status 6 weeks post-operatively. Return to baseline functional status at 6 weeks post-operatively was not improved when these women were randomized to enhanced pre-operative geriatric assessment versus routine care. These studies were limited by low numbers of very old women and women undergoing obliterative surgery, usually recommended for women with higher co-morbidities and lower functional status.

Post-operative outcomes have been traditionally measured in terms of medically documented complications such as infection, organ injury, cardiac and pulmonary complications. However, studies from other surgical specialties suggest that older subjects undergoing surgery can suffer from significant worsening of functional status resulting in disability, need for long-term care, and dependency at home. Objective markers of functional status, co-morbidity and frailty are potential useful predictors of post-operative complications following surgery in the elderly. However, there is lack of data on the functional status of elderly women undergoing POP surgery, as well as on factors influencing recovery from surgery. The goal of our study is to explore the utility of pre-operative markers of functional status, co-morbidities and frailty to explain post-operative morbidities in elderly women undergoing surgical treatment for pelvic organ prolapse.
