Evolutionen

Adherence - historie Hippokrates tid: Effekten af diverse miksturer bliver noteret! 1979: Første workshop om monitorering af medicincompliance.

Adherence - baggrund I USA anslås mangelfuld adherence at koste 300 millioner dollars per år. I medicinske forsøg, har personer med dårlig adherence dårligere prognose end dem med god adherence. (gælder både for aktiv medicin og placebo).

Adherence sygdom Størst ved akut sygdom! Drastisk fald ved kronisk sygdom til ca. 50% (WHO). Lung Health Study 60% efter 1 år, 50% efter 5 år.

Fordelingen af adherence Adherent Partial Adherent Non-adherent 1/3 1/3 1/3

LÆGEN Retningslinjer Diagnosticere - hvad er indiceret til hvem Medicin/behandling Hvordan tages og virker det/og virker det? Pris Hvad koster det er der alternativer

PATIENTEN Hvorfor og hvordan skal jeg tage min medicin/behandling Vide og forstå Hvornår skal jeg gå til læge eller tage ekstra Mestring/Selvmedicineringsplaner Hvad kan jeg forvente af min sygdom Uddannelse i sygdom og egenomsorg

Long-term CPAP Compliance in Women (705) with Obstructive Sleep Apnoea ERJ Express. Published on February 8, 2013 The median CPAP use was 6 (IQR 4-7)hours/day.

CPAP-behandling varighed CPAP therapy for 4 hours/night experienced significant reductions in: systolic and diastolic blood pressure (P=0.001 and P=0.006, respectively); global cardiovascular disease risk (P=0.001); total cholesterol (P=0.002); insulin resistance (P=0.031); oxidative stress (P=0.004); and inflammation (P=0.037).

Prognosis of Patients With Heart Failure and Obstructive Sleep Apnea Treated With Continuous Positive Airway Pressure 32 patients were classified as more compliant (average usage, 6.0 h), and 33 patients were classified as less compliant (average usage, 3.5 h). CHEST 2008; 133:690 696)

Improvements in OSA symptoms, as measured by the FOSQ, were associated with higher CPAP adherence (r.50; p.0001).

(1) poor users (n 14), who used PAP an average of 2 h per night; (2) ) moderate users (n 25), who used PAP an average of 2 to 6 h per night; (3) optimal users (n 19), who used PAP an average of 6 h per night. (CHEST 2006; 130:1772 1778)

475 CPAP patients questionnaire There was a negative correlation of the ESS score with daily CPAP usage (r = 0.33, p < 0.001), indicating that patients with longer daily CPAP usage tended to report less daytime sleepiness. <6.5 h/day (n = 228) >6.5 h/day (n = 249) <6.5 h/day showed a significantly higher ESS score (median = 10; IQR: 7 13 vs. median = 7; IQR: 4 10; p < 0.001).

Konklusion Ingen high grade evidens for hvor meget er nok Ingen større undersøgelser ift % af søvn 5 timer synes at være mest anbefalet Formentlig stor individuel variation Behov for undersøgelser
