Table 1.
Summary of demographic characteristics [percentage or means (standard deviation)] of in-center HD patients by dialysis schedule, in 2013.
Table 2.
Number and rate (per year) of all-cause total ED visits, ED visits followed by hospital admission, ED visits not followed by hospital admission, total hospital admissions, and hospital admission not preceded by an ED visit, among in-center HD patients, by dialysis schedule and day of the week.
Fig 1.
Adjusted incidence rate ratio (95% CI) of (A) total ED visits and (B) total hospital admissions among in-center HD patients in 2013, by dialysis schedule (MWF or TTS) and day of the week, compared with the MWF group in Sunday (reference group). Incidence rate ratios were adjusted for age, sex, race/ethnicity, the Charlson Comorbidity Index score, HD vintage, HD session length, Kt/V, IDWG, and BMI.
Fig 2.
Adjusted incidences rate ratio (95% CI) of (A) ED visits not followed by a hospital admission, (B) ED visits followed by a hospital admission, and (C) hospital admissions not preceded by an ED visit among in-center HD patients in 2013, by dialysis schedule (MWF or TTS) and day of the week, compared with the MWF group on Sunday (reference group). Incidence rate ratios were adjusted for age, sex, race/ethnicity, the Charlson Comorbidity Index score, HD vintage, HD session length, Kt/V, IDWG, and BMI.
Fig 3.
Adjusted incidence rates (per 100/year) of (A, B) cause-specific ED visits and (C, D) cause-specific hospital admissions for in-center HD patients in 2013, by dialysis schedule (MWF or TTS), day of the week, and primary diagnosis. Incidence rates were adjusted for age, sex, race/ethnicity, the Charlson Comorbidity Index score, HD vintage, HD session length, Kt/V, IDWG, and BMI.
Fig 4.
Comparison of (A) findings from the main analysis of total ED visits in Fig 1A with (B) findings from the restricted sensitivity analysis of total ED visits. Each figure shows the adjusted incidence rate ratio (95% CI) of total ED visits, by dialysis schedule (MWF or TTS) and day of the week, compared with the MWF group on Sunday (reference group). Incidence rate ratios were adjusted for age, sex, race/ethnicity, the Charlson Comorbidity Index score, HD vintage, HD session length, Kt/V, IDWG, and BMI.
Fig 5.
Comparison of (A) findings from the main analysis of total hospital admissions in Fig 1B with (B) findings from the restricted sensitivity analysis of total hospital admissions. Each figure shows the adjusted incidence rate ratio (95% CI) of total hospital admissions, by dialysis schedule (MWF or TTS) and day of the week, compared with the MWF group on Sunday (reference group). Incidence rate ratios were adjusted for age, sex, race/ethnicity, the Charlson Comorbidity Index, HD vintage, HD session length, Kt/V, IDWG, and BMI.
