Temporal dynamics of pain: an application of regime-switching models to ecological momentary assessments in patients with rheumatic diseases

This study examined whether regime-switching models, which capture processes characterized by recurrent shifts between different states, provide clinically relevant information for characterizing individuals based on their temporal pain patterns. Patients with rheumatic diseases (N = 116) provided 7 to 8 momentary pain ratings per day for 2 weekly periods, separated by 3 months. Regime-switching models extracted measures of Average pain (mean level over time), Amplitude (magnitude of shifts in pain levels), Persistence (average duration of pain states), and Dominance (relative duration of higher vs lower pain states) for each patient and assessment period. After controlling for Average pain, the Persistence of pain states uniquely predicted emotional functioning measures, whereas the Dominance of higher pain uniquely predicted physical functioning and pain interference. Longitudinal analyses of changes over the 3 months largely replicated cross-sectional results. Furthermore, patients' retrospective judgments of their pain were uniquely predicted by Amplitude and Dominance of higher pain states, and global impressions of change over the 3 months were predicted by changes on Dominance, controlling for Average pain levels. The results suggest that regime-switching models can usefully capture temporal dynamics of pain and can contribute to an improved measurement of patients' pain intensity.

RESUMO Objetivo: Avaliar o impacto de um protocolo de manejo da dor e redu ção do consumo de opioides no consumo geral de opioides e nos desfechos clínicos. Métodos: Estudo em centro único, quasi-experimental, retrospectivo, de coortes antes e depois. Utilizamos uma série temporal interrompida para analisar as alterações no nível e na tendência de utilização d e diferentes analgésicos. Foram usadas comparações bivariadas nas coortes antes e depois, regressão logística e regressão quantílica pa...

Conclusion: Ambas as escalas são adequadas para a avaliação da dor em pacientes intubados orotraquealmente, internados em unidade de terapia intensiva, contudo, apresentam limitações em populações específicas como doentes vítimas de trauma, queimados e do f oro neurocirurgico. É sugerida a realização de mais estudos sobre o tema e em populações específicas.

ConclusionsBased on a moderate level of certainty, orthodontic patients treated with Invisalign appear to feel lower levels of pain than those treated with fixed appliances during the first few days of treatment. Thereafter (up to 3  months), differences were not noted. Malocclusion complexity level among included studies was mild. Pain is one of many considerations and predictability and technical outcome are more important, mainly considering that the difference does not seem to occur after the first months of the orthodont ic treatment.
