HRs are adjusted for age (entered as a continuous variable), gender, socioeconomic deprivation decile, ethnicity, previous history of specific conditions (see list in table 1), number of long-term conditions, predictive risk score, emergency admissions (previous year), emergency admissions (previous month), elective admissions (previous year), elective admissions (previous month), outpatient attendances (previous year) and outpatient attendances (previous month).
ACS, ambulatory care sensitive; HRs, hazards ratios.
