Prolonged Mechanical Ventilation: A Comparison of Patients Treated at Home Compared With Hospital Long-Term Care

Abstract

ObjectiveTo compare the characteristics of patients treated with invasive prolonged mechanical ventilation (PMV) at home or in hospital long-term care (HLTC), specifically focusing on medical and functional status, caregiver strain, 6-month outcomes, and health maintenance organization (HMO) costs. DesignObservational study. SettingA single HLTC and home hospital, serving a defined catchment area in the greater Jerusalem area, Israel. ParticipantsA total of 120 PMV patients aged ≥18 years, all insurees of the same HMO. All PMV patients in the local HMO were approached, of whom 46 of 47 home PMV and 74/76 HLTC patients were enrolled. MeasurementsMedical and sociodemographic factors, Barthel Index, Short Geriatric Depression Score, modified Caregiver Strain Index; 6-month follow-up for hospitalization, infections, pressure sores, and mortality; HMO costs. ResultsHome PMV was associated with younger age, improved functional status, financial difficulty, less comorbidity, and longer duration of PMV. Primary reasons for home PMV were degenerative neuromuscular disease and chronic lung disease, compared with acute illnesses with or without resuscitation among HLTC patients. Most home patients were alert and able to communicate (n = 40/46) versus HLTC (n = 22/74), and reported less depression. Caregiver strain was similar for home and HLTC. Among HLTC versus home patients, 6-month mortality (27% vs 7%, P = .012) and frequency of pressure sores (45% vs. 29%, P = .042) were higher in HLTC, with no differences for infection rates or hospitalization. In multivariate analyses, being treated at home with PMV was significantly associated with being able to communicate, lower age, financial difficulties, and improved functional status. HMO costs were one-third for home PMV versus HLTC. Conclusions and ImplicationsDiffering profiles were described for home and HLTC PMV patients, with lower rates of depression, pressure sores, mortality, and one-third the cost to HMO at home. Caregiver strain was similar irrespective of site of care. With appropriate targeting for eligible patients, home PMV is a viable and financially beneficial option.
