Table 2.

Use of health care per patient in standard of care (SOC) or telemonitoring solution for a 6-month period. Statistics were calculated with the Wilcoxon signed rank test or the Pearson chi-square test with Yates correction for the binary variables.

Variable			SOC (n=43)		Telemonitoring (n=43)		Absolute change (relative change; %)		P value for difference
All-cause hospitalizations
	Patients with ≥1 event, n (%)	23 (53)		14 (33)		–9 (–39)		.08
	Inpatient days, mean (95% CI)	2.9 (1.6)		1.7 (1.2)		–1.2 (–41)		.20
Hospitalizations for cardiovascular cause other than HFa
	Patients with ≥1 event, n (%)	6 (14)		<5 (~10)		<5 (~–30)		.70
	Inpatient days, mean (95% CI)	0.2 (0.3)		0.02 (0.05)		–0.16 (–88)		.40
Hospitalizations for HF
	Patients with ≥1 event, n (%)	20 (47)		6 (14)		–14 (–70)		.002
	Mean inpatient days, days (95% CI)	2.3 (1.3)		1.2 (1.1)		–1.1 (–48)		.17
Mean number of emergency care visit for cardiovascular cause, n (95% CI)			1.3 (0.4)		0.7 (0.3)		–0.6 (–44)		.006
Mean number of phone calls to primary care, n (95% CI)			3.9 (1.3)		2.5 (0.9)		–1.4 (–36)		.01
Mean number of phone calls to secondary care, n (95% CI)			2 (0.7)		8.3 (1.7)		6.3 (+318)		<.001
Mean number of all-cause primary care visits, n (95% CI)			2.8 (1.1)		4 (1.8)		1.2 (+44)		.02
Mean number of secondary care visits (cardiology), n (95% CI)			1.8 (0.5)		1.9 (0.6)		0.1 (+8)		.80
