Report Definitions

This article contains report definitions to support the understanding of how SSNAP scores and key indicators are calculated. 

Clock start	The term 'Clock start' is used throughout SSNAP reporting to refer to the date and time of arrival at first hospital for newly arrived patients, or to the date and time of symptom onset if patient already in hospital at the time of their stroke. i.e. the date and time of first arrival at hospital (Q1.13) for newly arrived patients (Q1.10 is "No"), or the date and time of onset/awareness of symptoms (Q1.11) if patient was already an inpatient at the time of stroke (Q1.10 is "Yes").
Proportion	The number of patients who achieved the indicator (numerator) over the number of applicable patients (if it is expressed as a percentage then this number is multiplied by 100).
Percentage	The number of patients who achieved the indicator (numerator) multiplied by 100 over the number of applicable patients.
Cohort of patients In SSNAP reporting, the processes of care and patient outcomes are reported in two ways - patient-centred and team-centred.
Patient-centred	Patient-centred attribute results to every team which treated the patient at any point in their care. This recognises that the stroke care pathway usually involves many teams treating the patient at different points. This holistic approach is aimed at encouraging teams to work closely together to ensure consistency of care. It is 'patient-centred' because it describes the care and outcomes from the patient perspective, regardless of which team treated the patient.
Team-centred	Team-centred attribute the results to the team considered to be most appropriate to assign the responsibility for that measure to. It is recognised that it is useful to provide results on a team-centred basis so that teams can see the results for the interventions delivered.
Patient-centred 72h cohort	This section shows the patient-centred results for the first 72 hours of care and is based on records locked to 72 hours for patients who arrived at hospital (or had their stroke in hospital) in the respective reporting period.
Team-centred 72h cohort	The team-centred results for the first 72 hours of care are based on records locked to 72 hours for patients who arrived at hospital (or had their stroke in hospital) in the respective reporting period, and attributed to the first team which treated the patient, regardless of which teams locked the record to 72 hours (i.e. the second team may have locked the record to 72 hours, but results are attributed to first team).  Please note: for the team-centred 72h results, all measures are attributed to the first team which treated the patient. Although this does not take account of the very small number of patients transferred within 72h, it ensures that the results are as simple as possible to follow.
Patient-centred post-72h cohort	This section shows the patient-centred results between 72 hours and discharge from inpatient care and is based on records locked to discharge for patients who were discharged from inpatient care in the respective reporting period.  It is attributed to all teams which treated the patient at any point in their care.  This means that a team which only treated the patient during the first 72 hours will still have the results for this patient's care between 72 hours and discharge from inpatient care. We hope that this will encourage an open dialogue between teams treating patients along a care pathway and that teams treating the patient initially reflect on the continuing care they receive, as this will also impact upon the initial team's longer term outcome results.
Team-centred post-72h cohort: 7 day team	For the team-centred post-72h results, measures are attributed to teams depending on the point at which they treated the patient along the inpatient pathway.  Results attributed to the '7 day team' are attributed to the team which had the patient in their care at 7 days following clock start (or, if the length of stay as an inpatient was less than 7 days, the team which discharged the patient from inpatient care). These results include measures which are considered to be most appropriately designated to the team which had the patient in their care at 7 days, but does not necessarily indicate that the care was received within 7 days.  For instance, one measure in this section is whether the patient had a urinary continence plan by discharge. It is attributed to the team which had the patient at 7 days, but the measure is whether the patient had the plan by discharge, regardless of which team provided the plan.  The team-centred post-72h 7-day results are based on records locked to discharge for patients who were discharged from inpatient care in the respective reporting period.
Team-centred post-72h cohort: inpatient discharge team	For the team-centred post-72h results, measures are attributed to teams depending on the point at which they treated the patient along the inpatient pathway.  Results attributed to discharging team are attributed to the team which discharged the patient from inpatient care. The team-centred post-72h inpatient discharge results are based on records locked to discharge for patients who were discharged from inpatient care in the respective reporting period.
Team-centred post-72h cohort: all teams	For the team-centred post-72h results, measures are attributed to teams depending on the point at which they treated the patient along the inpatient pathway.  Results attributed to all teams are for measures which are answered by every patient by every team along the pathway (therapy intensity, rehab goal setting, length of stay in hospital and on stroke unit, and discharge /transfer destination).  These results are based only on what the team provided rather than what the patient received across the whole pathway, e.g. the team-centred length of stay is the length of stay at each particular team compared to the patient-centred length of stay which is the length of stay the patient had across all teams.  The team-centred post-72h all teams results are based on records locked to discharge or where a transfer to another team has been actioned in the respective reporting period. This includes all records which have either been discharged out of inpatient care or transferred to another inpatient team.
Thrombectomy cohort	Results attributed to the thrombectomy centre that performed the thrombectomy, irrespective of if they were directly admitted to the thrombectomy centre or transferred from the first admitting hospital.  The thrombectomy cohort is based on records locked to 72 hours for patients who arrived at hospital (or had their stroke in hospital) in the respective reporting period.
