---|---|---|---|---|---|
Paracetamol/acetaminophen, NSAIDs, oral or parenteral opioid | Hendriks et al. 2014–2015, [38, 48], NL, C | 330 dying people with dementia from 34 NHs (2007–2011); 43 % had AD | 2 weeks after death retrospective questionnaire to investigate association between QoL and pain | 11-item QUALID; no pain tool | In the last week of life, 52 % were found to be in pain; no differences between patients between advanced and less advanced dementia; 77 % received opioids (90 mg/24 h; 88 % by injection); 43 % opioid monotherapy, 57 % opioids + paracetamol. Cannot determine the most effective treatment of symptoms |
Paracetamol, morphine, buprenorphine, and/or pregabalin | Husebo et al. 2011–2014, [7, 37, 49, 50], N, A | 352 NH patients with advanced dementia (type unknown) and agitation from 60 NH clusters | CRCT over 12 weeks; NH clusters were randomized to an SPTP | CMAI NPI-NH MMSE MOBID-2 Pain Scale ADL |
Agitation reduced in the SPTP group (average reduction 17 % (p < 0.001, 95 % confidence interval −3.7 to −10.3) [37]. Verbally agitated behaviors, physically non-aggressive behaviors, and aggressive behaviors improved after 8 weeks (p < 0.001, p = 0.008, p = 0.037, respectively) [50]. Mood syndrome improved (p < 0.001), including depression (p = 0.025), apathy (p = 0.017), sleep (p = 0.050), and appetite (p = 0.005) [49]. Pain reduced in SPTP group compared with control (p < 0.001) at week 8, and pain scores worsened during washout (p = 0.022). Acetaminophen improved ADL function (p = 0.02) [7] |
