There is considerable overlap in symptomatology between chronic fatigue syndrome (CFS) and affective disorder. We report a comparison of depressive phenomenology and attributional style between a group of CFS subjects seen in a specialized medical setting, which included a high proportion with depression diagnosed by Research Diagnostic Criteria (RDC), and depressed controls seen in a specialized psychiatric setting. Significant symptomatic differences between the depressed CFS group and depressed controls were observed for features such as self-esteem and guilt as well as attribution of illness. All the CFS groups tended to attribute their symptoms to external causes whereas the depressed controls experienced inward attribution. This may have resulted from differences in the severity of mood disorder between the samples, but it is also suggested that an outward style of attribution protects the depressed CFS patients from cognitive changes associated with low mood but at the expense of greater vulnerability towards somatic symptoms such as fatigue.

Roughly half a million people die of cancer in sub-Saharan Africa every year. Despite rapid expansion of palliative care for cancer, coverage remains woefully inadequate. The WHO public health strategy for palliative care aims to increase access to palliative care services through its integration into health-care systems. We present the available evidence for the four WHO strategy pillars of policy, education, drug availability, and implementation, and propose a fifth pillar of research activity to stimulate improvement of care. Increased attention to the generation of research evidence is essential to achieve quality and coverage of appropriate palliative care for patients with advanced cancer in sub-Saharan Africa. The use of locally validated, patient-reported outcome measures is an important advance in the measurement and improvement of care and patient wellbeing. Palliative care for patients with cancer in Africa currently receives far less research attention than does palliative care for patients with HIV/AIDS, but in view of projected increasing cancer incidence in the region, generation of local evidence to inform and allow assessment of palliative care for patients with cancer is urgently needed.

The enormous burden of progressive, incurable disease in sub-Saharan Africa is reflected in the epidemiology of cancer and HIV. However, there has been little research activity and evidence generated to inform appropriate and effective responses. A collaborative of clinicians, academics and advocates have been active in the design, delivery and reporting of research activities in African palliative care. Here, they report the methodological, ethical, logistic and capacity-based challenges of conducting research in the sub-Saharan context from their experience. A number of strategies and responses are presented.

The increasing number of immigrants from African countries practicing female genital mutilation (FGM) has raised concern in Europe. Health care professionals have developed three main responses: (1) technical guidelines for clinical management; (2) codes of conduct on quality of care; and (3) specialised health services for medical and psychological care and counselling. Much remains to be done, however, to ensure adequate care in Europe: (1) medico-legal/ethical discussions; (2) development of protocols to assist in making informed decisions; and (3) development of guidelines on counselling, communication strategies, and referral procedures. All agencies working in the field of FGM should be interlinked at the national level, in which members of the affected communities should be included. At the European level, a coordinated approach between all agencies should be developed.

CONTEXT Although pain and burdensome symptoms among HIV-infected persons can be effectively managed, the availability of opioids and other symptom-controlling drugs is a particular challenge in sub-Saharan Africa. OBJECTIVES This study aimed to identify current drug availability and prescribing practices in 12 sub-Saharan African countries and to examine the barriers and potential facilitators for use of opioids and other key HIV/AIDS symptom-controlling drugs. METHODS This was a cross-sectional survey, integrating data from palliative care facilities and competent authorities within ministries of health in 12 African countries. RESULTS Of 62 responding facilities, problems were reported in accessing named nonopioids, with a small number of facilities unable to dispense them. Less than half the facilities were currently prescribing opioids of any strength. Further problems were identified in terms of the availability and supply continuity of named antiemetics and anxiolytics. The data identified a number of systemic problems, suggesting that opioid supply issues are similar to less controlled drugs, such as antiemetics. Among competent authorities, there was no agreement on whether further opioid expansion was possible. Integration of data from care facilities and competent authorities highlighted a disparity in the understanding of the availability of specific drugs, with competent authorities naming drugs that were not listed by any responding facility in their respective country. CONCLUSION This study shows that opioid expansion needs to balance supply and skills: Currently there are insufficient trained clinical personnel to prescribe, and supply is unreliable. Efforts to expand supply should ensure that they do not weaken current systems.

Background: World Health Organization’s essential drugs list can control the highly prevalent HIV-related pain and symptoms. Availability of essential medicines directly influences clinicians’ ability to effectively manage distressing manifestations of HIV. Aim: To determine the availability of pain and symptom controlling drugs in East Africa within President’s Emergency Plan for AIDS Relief–funded HIV health care facilities. Design: Directly observed quantitative health facilities’ pharmacy stock review. We measured availability, expiration and stock-outs of specified drugs required for routine HIV management, including the World Health Organization pain ladder. Setting: A stratified random sample in 120 President’s Emergency Plan for AIDS Relief–funded HIV care facilities (referral and district hospitals, health posts/centres and home-based care providers) in Kenya and Uganda. Results: Non-opioid analgesics (73%) and co-trimoxazole (64%) were the most commonly available drugs and morphine (7%) the least. Drug availability was higher in hospitals and lower in health centres, health posts and home-based care facilities. Facilities generally did not use minimum stock levels, and stock-outs were frequently reported. The most common drugs had each been out of stock in the past 6 months in 47% of facilities stocking them. When a minimum stock level was defined, probability of a stock-out in the previous 6 months was 32.6%, compared to 45.5% when there was no defined minimum stock level (χ2 = 5.07, p = 0.024). Conclusion: The data demonstrate poor essential drug availability, particularly analgesia, limited by facility type. The lack of strong opioids, isoniazid and paediatric formulations is concerning. Inadequate drug availability prevents implementation of simple clinical pain and symptom control protocols, causing unnecessary distress. Research is needed to identify supply chain mechanisms that lead to these problems.

Despite being declared a basic human right, access to adult and pediatric palliative care for millions of individuals in need in low- and middle-income countries (LMICs) continues to be limited or absent. The requirement to make palliative care available to patients with cancer is increasingly urgent because global cancer case prevalence is anticipated to double over the next two decades. Fifty percent of these cancers are expected to occur in LMICs, where mortality figures are disproportionately greater as a result of late detection of disease and insufficient access to appropriate treatment options. Notable initiatives in many LMICs have greatly improved access to palliative care. These can serve as development models for service scale-up in these regions, based on rigorous evaluation in the context of specific health systems. However, a multipronged public health approach is needed to fulfill the humane and ethical obligation to make palliative care universally available. This includes health policy that supports the integration of palliative care and investment in systems of health care delivery; changes in legislation and regulation that inappropriately restrict access to opioid medications for individuals with life-limiting illnesses; education and training of health professionals; development of a methodologically rigorous data and research base specific to LMICs that encompasses health systems and clinical care; and shifts in societal and health professional attitudes to palliative and end-of-life care. International partnerships are valuable to achieve these goals, particularly in education and research, but leadership and health systems stewardship within LMICs are critical factors that will drive and implement change.

CONTEXT The incidence of life-limiting progressive disease in sub-Saharan Africa presents a significant clinical and public health challenge. The ability to easily measure patient outcomes is essential to improving care. OBJECTIVES The present study aims to determine the specific factors (if any) that underpin the African Palliative Care Association African Palliative Outcome Scale to assist the analysis of data in routine clinical care and audit. METHODS Using self-reported data collected from patients with HIV infection in eastern and southern Africa, an exploratory factor analysis was undertaken with 1337 patients; subsequently, a confirmatory analysis was done on two samples from separate data sets (n = 445). RESULTS Using exploratory factor analysis initially, both two- and three-factor solutions were examined and found to meet the criteria for simple structure and be readily interpretable. Then using confirmatory factor analysis on two separate samples, the three-factor solution demonstrated better fit, with Goodness-of-Fit Index values greater than 0.95 and Normative Fit Index values close to 0.90. The resulting three factors were 1) physical and psychological well-being, 2) interpersonal well-being, and 3) existential well-being. CONCLUSION This analysis presents an important new opportunity in the analysis of outcome data for patients with progressive disease. It has advantages over both the total scoring of multidimensional scaling (which masks differences between domains) and of item scoring (which requires repeated analyses). The three factors map well onto the underlying concept and clinical goals of palliative care, and will enable audit of facility care.

Purpose of reviewThis narrative review examines evidence for models of palliative and end-of-life (eol) care delivery in sub-Saharan Africa (SSA) since 2010. It highlights recent developments, on-going challenges and innovative approaches used to address obstacles to increased access to care. Recent findingsElectronic databases were searched for the literature published in English during the period 2010–2012 around broad thematic areas of palliative and eol care delivery models in SSA. Literature showed increased palliative and eol care service development, underpinned by advocacy work undertaken by regional and national palliative care associations. Despite this increase, care provision remains inadequately integrated in national public health agendas and systems. Consequently, it continues to be heavily reliant upon nongovernmental, community-based and home-based care (HBC) models. Efforts are, however, underway to integrate palliative care into national health systems, which should increase access to care. National policies and government financing will be important to sustain this integration. SummaryAlthough community and HBC programs remain primary models of palliative and eol care delivery in SSA, there is an urgent need to develop a public health approach that integrates care into national health systems to increase accessibility.

UNLABELLED This study aimed to determine the prevalence, intensity, associated factors, and effect of pain among ambulatory HIV/AIDS patients. Three-hundred two adult ambulatory HIV/AIDS patients were consecutively recruited from HIV/AIDS outpatient clinics at 2 teaching hospitals in Uganda. The presence and intensity of pain were self-reported using the Brief Pain Inventory (BPI); symptom data were collected using the Memorial Symptom Assessment Scale (MSAS-SF); and quality of life (QOL) was assessed using the Medical Outcome Scale-HIV. Forty-seven percent reported pain in the 7 days prior to the survey and pain was a symptom at the time of diagnosis for 68%. On the 0 to 10 numeric scale, 53% reported mild pain (1-4 rating), 20% reported moderate pain (5-6 rating) while 27% reported severe pain (7-10 rating). Gender was not associated with pain intensity, but reduced functional performance, increasing number of symptoms, advanced HIV disease , physical symptom distress (MSAS-SF), and number of health comorbidities were significantly associated with pain intensity (P < .04). Increasing pain intensity was associated with greater functional ability impairment (BPI functional interference index) and poorer QOL. Pain is a common symptom among ambulatory HIV/AIDS patients and has a debilitating effect on QOL. There is a significant unmet need for pain relief in the population. PERSPECTIVE This article discusses the characteristics and effect of pain on function and QOL in East African patients. It also contributes information on characteristics of HIV/AIDS adult patients in the East Africa demonstrating the aspects in which pain is similar across different cultures.
