A Telemedicine Intervention to Ensure the Correct Usage of Inhaler Devices.

Background: Chronic obstructive pulmonary disease and asthma patients' use of inhalers is error prone. Introduction: This study evaluated telemedicine to improve the use of inhalers. Materials and Methods: Prospective, single-center pilot study in 50 patients with long-term prescription of inhaled medicine and ongoing home health care visits. In an initial telemedicine intervention, tablet devices were used by the patient to record inhaler use at home in the real-time remote presence of a physician. Errors were identified, explained to the patient, and corrected remotely. When necessary, further telemedicine interventions were scheduled at 24-48 h intervals. Follow-up interventions were performed during routine outpatient visits. Patient satisfaction was evaluated on a scale of 0 (completely unsatisfied) to 10 (completely satisfied). Results: An initial telemedicine intervention was conducted for 42 of the 50 patients included. In these patients, 96 initial inhaler medicine administration telemedicine interventions were performed, of which 94 were usable. In the initial interventions, 71 errors were identified, of which 22 (31%) were considered critical. In 81 follow-up interventions in 39 patients (median delay 256 days), 32 errors were identified (p < 0.001 vs. initial 71 errors), of which 7 were critical (p = 0.0017 vs. initial 22 errors). Discussion: This paves the way for future studies testing putative benefits of telemedicine regarding inhaled drug delivery, treatment adherence, disease control, quality of life, and health care burden and costs. Conclusions: A telemedicine intervention aimed at improving the administration of inhaled medication by adult patients at home is feasible, highly appreciated by patients, and effective at correcting medicine administration errors.

Overnight Pulse Oximetry to Determine Prognostic Factors in Subjects With Amyotrophic Lateral Sclerosis.

BACKGROUND: The objective of the current study was to determine whether overnight pulse oximetry in patients with amyotrophic lateral sclerosis is prognostic of the onset of awake respiratory failure and hospital admissions. METHODS: This was an observational study in a cohort of subjects with amyotrophic lateral sclerosis. The study included subjects with a baseline [Formula: see text] ≥ 94% on home overnight pulse oximetry testing. Patients age ≥ 80 y and those with comorbidities and with poor short-term prognosis or sleep apnea were excluded. The subjects were classified as nocturnal desaturators according to percentage of sleep time with [Formula: see text] < 90% (T90) > 10%. RESULTS: A total of 76 subjects were included: 40 men (53%), mean ± SD age 60 ± 14.4 y, mean ± SD body mass index 25.7 ± 4.60 kg/m2, and spinal presentation in 63.2%. After overnight pulse oximetry, 20 subjects (26%) were classified as desaturators and 56 (74%) as non-desaturators. In the first year, the subjects with nocturnal desaturation had respiratory failure more often compared with the subjects without desaturation (35% vs 10.91%; P = .02) and had a higher risk of developing respiratory failure during the course of the study (hazard ratio 2.48; P = .030). The desaturator group also had a higher rate of ≥ 1 admission (40% vs 7.3%; P = .01) and a higher likelihood of respiratory-related hospitalization (hazard ratio 2.41; P = .02). Median survival was almost 1 year less if T90 > 10% was observed in the overnight pulse oximetry: 21 months versus 32 months survival if T90 was ≤ 10%. CONCLUSIONS: In subjects with amyotrophic lateral sclerosis, nocturnal desaturation conferred a higher risk of respiratory failure and poorer prognosis. Even in the absence of other clinical criteria, early pulse oximetry should be performed and the need for nocturnal ventilatory support assessed.
