Abstract

BackgroundDespite a high incidence of life-limiting disease, there is a deficit of palliative care outcome evidence in sub-Saharan Africa. Providers of end of life care call for appropriate measurement tools. The objective is to compare four approaches to self-report pain and symptom measurement among African palliative care patients completing the African Palliative Care Association African Palliative Outcome Scale (APCA African POS).MethodsPatients were recruited from five services (4 in South Africa and 1 in Uganda). Research nurses cross-sectionally administered POS pain and symptom items in local languages. Both questions were scored from 0 to 5 using 4 methods: verbal rating, demonstrating the score using the hand (H), selecting a face on a visual scale (F), and indicating a point on the Jerrycan visual scale (J). H, F and J scores were correlated with verbal scores as reference using Spearman’s rank and weighted Kappa. A Receiver Operating Characteristic (ROC) analysis was performed.Results315 patients participated (mean age 43.5 years, 69.8% female), 71.1% were HIV positive and 35.6% had cancer, 49.2% lived in rural areas. Spearman’s rank correlations for pain scores were: H: 0.879, F: 0.823, J: 0.728 (all p < 0.001); for symptoms H: 0.876, F: 0.808, J: 0.721 (all p < 0.001). Weighted Kappa for pain was H: 0.798, F: 0.719 J: 0.548 and for symptoms: H: 0.818, F: 0.718, J: 0.571. There was lower agreement between verbal and both hand and face scoring methods in the Ugandan sample. Compared to the verbal scale the accuracy of predicting high pain/symptoms was H > F > J (0.96–0.89) in ROC analysis.ConclusionsHands and faces scoring methods correlate highly with verbal scoring. The Jerrycan method had only moderate weighted Kappa. POS scores can be reliably measured using hand or face score.

Highlights

  • In sub-Saharan Africa the incidence of life limiting diseases such as HIV and cancer presents a major clinical and public health challenge

  • As well as having utility in routine clinical practice, outcome measurement using validated tools is crucial to inform education, compare service models, monitor the development of palliative care, enhance its quality through clinical audit, and to ensure equity of access to good quality care [6]. They are essential in the generation of evidence, which can be considered the fifth pillar of the World Health Organization (WHO) public health palliative care strategy [7]

  • This study is an analysis of cross-sectional APCA African Palliative Care Outcome Scale (POS) data from a sample of patients with cancer or HIV at five palliative care facilities in two sub-Saharan countries (Uganda and South Africa)
