Pandemic disrupted the utilization of women’s preventive health services The COVID-19 pandemic knocked many women off schedule for important health appointments, a new study finds, and many didn't get back on schedule even after clinics reopened. The effect may have been greatest in areas where such care is already likely falling behind experts' recommendations. The study, by health care researchers in the University of Michigan Institute for Healthcare Policy and Innovation, looks at screenings for breast cancer, cervical cancer and sexually transmitted infections (STI), as well as two types of birth control care: prescriptions for oral contraceptives and insertions of longer-acting devices.
