DE-RESTRICT: Deimplementing Activity Restriction for Preterm Birth Prevention

Inclusion Criteria: * For Providers: Physicians, midwives, physician assistants, nurse practitioners, nurses, nursing assistants, medical assistants, and other healthcare staff who provide or participate in prenatal or high-risk pregnancy care or consultation at a participating site. * For Patients: Secondary patient-reported outcomes draw on pregnant individuals at high risk for preterm birth (qualifying diagnoses include short cervix, cervical insufficiency, multiple gestation, preterm labor, preterm contractions, vaginal bleeding, placental conditions, or a history of prior preterm birth), between 0 and 12 weeks postpartum for the survey measures. The activity restriction recommendation measure is collected through the Take Home Electronic Assessment (THEA) and therefore reaches only patients enrolled in THEA, at 33 weeks of gestation, across all periods; in the pre-deimplementation and post-deimplementation periods the additional survey battery is sent only to patients with a qualifying high-risk diagnosis. Exclusion Criteria: * For Providers: Staff who self-exclude by choosing not to interact with deimplementation meetings and communications * For Patients: Patients are excluded if they are unable to walk or are hospitalized without discharge home before delivery after the qualifying diagnosis is made.
