Measure | Definition |
---|---|

Density (UPC) | max where N = total visits |

n = number visits to _{i}i provider^{th} | |

Dispersion (COC) | where N = total visits |

n = total visits to _{i}i provider^{th} | |

p = total number of providers | |

Sequence (SECON) | where N = total visits |

Entropy/Disorganization (VE) | |

where | |

n = the number of visits to the i_{i}^{th} provider | |

k = the total number of possible providers | |

N = the total number of visits |

COC, dispersion continuity of care; SECON, sequence continuity; UPC, usual provider continuity; VE, visit entropy.
