Working with ICU datasets, especially with publicly available ones as provided by [PhysioNet](https://physionet.org) in R is facilitated by `ricu`, which provides data access, a level of abstraction to encode clinical concepts in a data source agnostic way, as well as classes and utilities for working with the arising types of time series datasets.
## Installation
Currently, installation is only possible from github directly, using the `remotes` if installed
```{r gh-rem, eval = FALSE}
remotes::install_github("eth-mds/ricu")
```
or by sourcing the required code for installation from github by running
```{r gh-dir, eval = FALSE}
rem <- source(
paste0("https://raw.githubusercontent.com/r-lib/remotes/main/",
"install-github.R")
)
rem$value("eth-mds/ricu")
```
In order to make sure that some useful utility packages are installed as well, consider installing the packages marked as `Suggests` as well by running
```{r gh-all, eval = FALSE}
remotes::install_github("eth-mds/ricu", dependencies = TRUE)
```
instead, or by installing some of the utility packages (relevant for downloading and preprocessing PhysioNet datasets)
```{r deps-util, eval = FALSE}
install.packages("xml2")
```
and demo dataset packages
```{r deps-data, eval = FALSE}
install.packages(c("mimic.demo", "eicu.demo"),
repos = "https://eth-mds.github.io/physionet-demo")
```
explicitly.
## Data access
Out of the box (provided the two data packages `mimic.demo` and `eicu.demo` are available), `ricu` provides access to the demo datasets corresponding to the PhysioNet Clinical Databases eICU and MIMIC-III. Tables are available as
```{r mimic-adm}
mimic_demo$admissions
```
and data can be loaded into an R session for example using
```{r mimic-ts}
load_ts("labevents", "mimic_demo", itemid == 50862L,
cols = c("valuenum", "valueuom"))
```
```{r mimic-ts-print, echo = FALSE}
load_ts("labevents", "mimic_demo", itemid == 50862L,
cols = c("valuenum", "valueuom"))[]
```
which returns time series data as `ts_tbl` object.
