nhds_adult: Return adult, pediatric or just neonatal elements from the...

In nhds: National Hospital Discharge Survey 2010 Data

Description

The age in the adult data is all specified in years, so the 'age_unit' column is dropped. The 'age_unit' field is retained when returning pediatric data.

Usage

nhds_adult(nhds_data = nhds::nhds2010, rename_age = TRUE)

nhds_adults(nhds_data = nhds::nhds2010, rename_age = TRUE)

nhds_pediatric(nhds_data = nhds::nhds2010)

nhds_peds(nhds_data = nhds::nhds2010)

nhds_neonatal(nhds_data = nhds::nhds2010, rename_age = TRUE)

nhds_neonatal_not_newborn(nhds_data = nhds::nhds2010,
  rename_age = TRUE)

nhds_neonate_not_newborn(nhds_data = nhds::nhds2010, rename_age = TRUE)

nhds_neonate(nhds_data = nhds::nhds2010, rename_age = TRUE)

nhds_infant(nhds_data = nhds::nhds2010, rename_age = TRUE)

nhds_infant_not_neonate(nhds_data = nhds::nhds2010, rename_age = TRUE)

nhds_newborn(nhds_data = nhds::nhds2010)

nhds_newborns(nhds_data = nhds::nhds2010)

Arguments

nhds_data	The NHDS data, default is 'nhds2010', which is the only year currently provided by this package.
rename_age	Logical, if 'TRUE', the default, the 'age' field is renamed to either 'age_days' (for neonatal data) or 'age_years' (for adult data).

Neonates and newborns

For newborns, when the 'newborn' field is 'TRUE', the 'age' is always zero at time of admission, so 'age' and 'age_unit' are dropped. This must therefore refer to birth in hospital, not an admission of a neonate who is transferred. For the same reason, 'adm_type' is dropped because it is always 'newborn'.

In contrast, neonatal data includes both in-hospital births and admissions of patients with age 28 or fewer days. Strangely, 'marital_status' is populated with a variety of values for the neonatal data, but all 'newborn' babies are considered 'single', so that field is dropped by 'nhds_newborn'.

Examples

head(nhds_adult())
# subset returned data directly
nhds_pediatric()[11:20, c("age_unit", "age")]
nhds_pediatric()[1:5, 1:7]
nhds_infant()[111:115, 1:7]
nhds_infant_not_neonate()[1:5, 1:7]
nhds_neonatal()[1:5, 1:7]
nhds_neonatal_not_newborn()[1:5, 1:7]
identical(nhds_neonatal()[1:10, ],
          nhds_neonate()[1:10, ])
identical(nhds_neonatal_not_newborn()[1:10, ],
          nhds_neonate_not_newborn()[1:10, ])
nhds_newborn()[1:5, 1:7]
