Active Comparator: Provider intervention
A web-based application called ProviderMinder has been developed and will be used to alert providers when a patient who has been lost-to-follow-up or has missed their Sickle Stroke Screen (TCD). This will allow providers to follow up with such patients and improve screening rates.

Other: Provider-level intervention
Provider minder is a provider-based scheduling and reminder system for stroke screening in SCD
Other Name: Provider Minder |
Active Comparator: Provider and Patient level intervention
A web-based application called ProviderMinder has been developed and will be used to alert providers when a patient who has been lost-to-follow-up or has missed their Sickle Stroke Screen (TCD). This will allow providers to follow up with such patients and improve screening rates. Additionally, sites will have a patient intervention of a single Sickle Stroke Screen coordinator who will interact directly with patients to schedule, reschedule, remind, and follow-up on stroke screening. This person will also act as a point of contact for any educational needs the patient may have. The second patient intervention will include the caregivers own mobile device. When Sickle Stroke Screens are scheduled the coordinator will ensure these appointments are directly put into the caregiver's mobile device calendar acting as an additional reminder for stroke screening.

- 1. Change in uptake and use of the stroke prevention guidelines (STOP Protocol) as defined in the NHLBI (National Heart, Lung, and Blood Institute) 2014 Sickle Cell Disease (SCD) Guidelines by assessing stroke risk with yearly TCD screens [ Time Frame: baseline-2 years ]The TCD measures the speed of blood flow in the blood vessels of the brain. Any unusually slow of fast speed may indicate a child is at a higher risk for stroke. By ensuring patients receive a yearly TCD more children will get a proper intervention and ideally prevent stroke.
- 2. Change in uptake and use of the stroke prevention guidelines (STOP Protocol) as defined in the NHLBI 2014 SCD Guidelines by implementing chronic red cell transfusion (CRCT) in patients noted to have abnormal TCD screens. [ Time Frame: baseline-2 years ]CRCT has been shown to severely decrease the incidence of stroke in patients who have had TCD screenings with an abnormal result.
- Change in uptake and use of the stroke prevention guidelines (STOP Protocol) as defined in the NHLBI (National Heart, Lung, and Blood Institute) 2014 SCD (Sickle Cell Disease) Guidelines by re-screening patients with conditional TCD screens [ Time Frame: baseline-2 years ]Patients who have a condition TCD are considered to of slightly higher risk than patients with a normal TCD. By re-screening these patients in a shorter time period, providers are able to confirm or reject the initial screening and make the best plan for stroke prevention depending on these outcomes.
- A difference in uptake and use of the stroke prevention guidelines (STOP Protocol) as defined in the NHLBI 2014 SCD Guidelines between between implementation arms measured by assessing yearly TCD screening rates. [ Time Frame: baseline-2 years ]Any difference in TCD implementation rates between each intervention arms will help determine optimal implementation procedures.
- Barriers to obtaining TCD screening [ Time Frame: baseline-2 years ]Participating sites will carry out key informant interviews with patients/caregivers and stakeholders will be analyzed using content analysis to identify themes pertaining to barriers to obtaining TCD screening, as well as overall perceptions of the intervention(s), barriers to implementing the intervention(s) and satisfaction with the intervention(s).
- Enablers to obtaining TCD screening [ Time Frame: baseline - 2 years ]Participating sites will carry out key informant interviews with patients/caregivers and stakeholders will be analyzed using content analysis to identify themes pertaining to enablers to obtaining TCD screening, as well as overall perceptions of the intervention(s), enablers to implementing the intervention(s) and satisfaction with the intervention(s).

Ages Eligible for Study: | 2 Years to 7 Years (Child) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | Yes |
Inclusion Criteria:
- Patients with sickle cell anemia (SCA) identified at each institution through International Classification of Diseases 9/10 (ICD-9/ICD-10) codes and local patient databases.
- Patients must have been seen by the designated institution (documented in medical record) a minimum of two times in the either inpatient or outpatient setting at the institution between the years of 01/01/2018-12/31/2019.
- Patients identified will include those currently aged 2-7. Thus children born from 2012 and onward.
- Patients already receiving primary or secondary stroke prevention therapy with CRCT will be included in registration in Web Data Coordination Unit (WEBDCU) but not included in PROVIDER MINDER as they do not require ongoing TCD/SICKLE STROKE SCREEN based on protocol.
Exclusion Criteria:
- Patients who do not have SCA
- Patients who were born before 2012 and therefore do not meet age criteria.
