| title: "Parsing model results files" | ||
| order: 8 | ||
| --- | ||
|
|
||
| Results from the model are viewable in the [NHP model outputs app](https://connect.strategyunitwm.nhs.uk/nhp/outputs/). | ||
| The outputs app provides a range of visualisations and summarisations of model results; however, users may wish to also conduct their own analysis based on the more detailed raw results file, which is available to download in [JSON format](https://en.wikipedia.org/wiki/JSON). | ||
| This page aims to explain the structure of the NHP model results JSON file. It reflects the structure of the results files from model v3.0. | ||
|
|
||
| The JSON results file has three keys: | ||
|
|
||
| - `params` The full parameters that were used for the model run. This is the JSON that is created and submitted to the model from the inputs app. | ||
| - `population_variants` An array of length equal to the number of Monte Carlo simulations. Lists the population variants that were utilised for each model run in the Monte Carlo simulations. | ||
| - `results` The actual model results, a set of 7 key-value pairs. | ||
| - `default` An array containing the model results grouped by `sitetret`, `measure`, and `pod`. Shows the results of the `principal` model run and the `baseline` value. Also shows the results of each of the Monte Carlo simulations in `model_runs`, the `lwr_ci`, `median` and `upr_ci` values from the Monte Carlo simulation runs, and the estimated year-by-year growth from baseline year to horizon year using the [principal projection parameters](https://connect.strategyunitwm.nhs.uk/nhp/project_information/user_guide/glossary.html#principal-projection) in `time_profiles`. | ||
| - `sex+age_group` An array containing the model results as found in `default`, but also including breakdowns by `age_group` and `sex`. The age groups used are: | ||
| - 0 | ||
| - 1-4 | ||
| - 5-9 | ||
| - 10-15 | ||
| - 16-17 | ||
| - 18-34 | ||
| - 35-49 | ||
| - 50-64 | ||
| - 65-74 | ||
| - 75-84 | ||
| - 85+ | ||
| - Unknown | ||
| - `age` An array containing the model results as found in `default`, but also including breakdowns by the age, in integers. | ||
| - `sex+tretspef` An array containing the model results as found in `default`, but also including breakdowns by grouped `tretspef` and `sex`. The `tretspef` groupings can be [seen here](https://connect.strategyunitwm.nhs.uk/nhp/project_information/data_extraction/inpatients.html#tretspef). | ||
| - `tretspef_raw+los_group` An array containing the model results for inpatients as found in `default`, but also including breakdowns by `tretspef_raw` and `los_group`. The Length of Stay groupings are: | ||
| - 0-day | ||
| - 1-day | ||
| - 2-day | ||
| - 3-day | ||
| - 4-7 days | ||
| - 15-21 days | ||
| - 22+ days | ||
| - 8-14 days | ||
| - `step_counts` An array containing the estimated [impact of changes](https://connect.strategyunitwm.nhs.uk/nhp/project_information/user_guide/glossary.html#impact-of-changes) caused by each parameter, also known as the `change_factor`. The data here is used for the 'waterfall diagrams' in the outputs app. The impact of each change factor is broken down by `activity_type`, `pod`, `measure`, and `sitetret`. We also break down the mitigators by each specific `strategy`. We show the estimated impact of each change factor for every Monte Carlo simulation in the `model_runs` and the estimated year-by-year impact of each change factor from baseline year to horizon year in the `time_profiles`. | ||
| - `tretspef_raw` An array containing the model results for outpatients as found in `default`, but also including breakdowns by grouped `tretspef_raw`. | ||
