Providers' perceptions of communication with patients in primary healthcare in Rwanda

BACKGROUND

Delivery of effective healthcare is contingent on the quality of communication between the patient and the healthcare provider. Little is known about primary healthcare providers' perceptions of communication with patients in Rwanda.

AIM

To explore providers' perceptions of patient-provider communication (PPC) and analyse the ways in which providers present and reflect on communication practice and problems.

METHODS

Qualitative, in-depth, semi structured interviews with nine primary health care providers. An abductive analysis supplemented by the framework method was applied. A narrative approach allowed the emergence of archetypical narratives on PPC.

RESULTS

Providers shared rich reflections on the importance of proper communication with patients and appeared committed to making their interaction work optimally. Still, providers had difficulty critically analysing limitations of their communication in practice. Reported communication issues included lack of communication training as well as time and workload issues. Two archetypes of narratives on PPC issues and practice emerged and are discussed.

CONCLUSION

While providers' narratives put patients at the centre of care, there were indications that patient-provider communication training and practice need further development. In-depth exploration of highlighted issues and adapted strategies to tackle communication drawbacks are prerequisites to improvement. This study contributes to the advancement of knowledge related to communication between the patient and the provider in a resource-limited setting.

Implementing One Health as an integrated approach to health in Rwanda

It is increasingly clear that resolution of complex global health problems requires interdisciplinary, intersectoral expertise and cooperation from governmental, non-governmental and educational agencies. ‘One Health’ refers to the collaboration of multiple disciplines and sectors working locally, nationally and globally to attain optimal health for people, animals and the environment. One Health offers the opportunity to acknowledge shared interests, set common goals, and drive toward team work to benefit the overall health of a nation. As in most countries, the health of Rwanda's people and economy are highly dependent on the health of the environment. Recently, Rwanda has developed a One Health strategic plan to meet its human, animal and environmental health challenges. This approach drives innovations that are important to solve both acute and chronic health problems and offers synergy across systems, resulting in improved communication, evidence-based solutions, development of a new generation of systems-thinkers, improved surveillance, decreased lag time in response, and improved health and economic savings. Several factors have enabled the One Health movement in Rwanda including an elaborate network of community health workers, existing rapid response teams, international academic partnerships willing to look more broadly than at a single disease or population, and relative equity between female and male health professionals. Barriers to implementing this strategy include competition over budget, poor communication, and the need for improved technology. Given the interconnectedness of our global community, it may be time for countries and their neighbours to follow Rwanda's lead and consider incorporating One Health principles into their national strategic health plans.

The Evolving Role of Physicians - Don't Forget the Generalist Primary Care Providers Comment on "Non-physician Clinicians in Sub-Saharan Africa and the Evolving Role of Physicians"

The editorial "Non-physician Clinicians in Sub-Saharan Africa and the Evolving Role of Physicians" by Eyal et al describes non-physician clinicians' (NPC) need for mentorship and support from physicians. We emphasise the same need of support for front line generalist primary healthcare providers who carry out complex tasks yet may have an inadequate skill mix.

Somatic tinnitus prevalence and treatment with tinnitus retraining therapy

OBJECTIVES

Somatic tinnitus originates from increased activity of the dorsal cochlear nucleus, a cross-point between the somatic and auditory systems. Its activity can be modified by auditory stimulation or somatic system manipulation. Thus, sound enrichment and white noise stimulation might decrease tinnitus and associated somatic symptoms. The present uncontrolled study sought to determine somatic tinnitus prevalence among tinnitus sufferers, and to investigate whether sound therapy with counselling (tinnitus retraining therapy; TRT) may decrease tinnitus-associated somatic symptoms.

METHODS

To determine somatic tinnitus prevalence, 70 patients following the TRT protocol completed the Jastreboff Structured Interview (JSI) with additional questions regarding the presence and type of somatic symptoms. Among 21 somatic tinnitus patients, we further investigated the effects of TRT on tinnitus-associated facial dysesthesia. Before and after three months of TRT, tinnitus severity was evaluated using the Tinnitus Handicap Inventory (THI), and facial dysesthesia was assessed with an extended JSI-based questionnaire.

RESULTS

Among the evaluated tinnitus patients, 56% presented somatic tinnitus-including 51% with facial dysesthesia, 36% who could modulate tinnitus by head and neck movements, and 13% with both conditions. Self-evaluation indicated that TRT significantly improved tinnitus and facial dysesthesia in 76% of patients. Three months of TRT led to a 50% decrease in mean THI and JSI scores regarding facial dysesthesia.

CONCLUSIONS

Somatic tinnitus is a frequent and underestimated condition. We suggest an extension of the JSI, including specific questions regarding somatic tinnitus. TRT significantly improved tinnitus and accompanying facial dysesthesia, and could be a useful somatic tinnitus treatment.

Spontaneous Pathology and Routine Clinical Pathology Parameters in Aging Beagle Dogs

AstraZeneca ran a bespoke study to generate age-matched clinical pathology and histopathology data from a cohort of Beagle dogs aged between 25 and 37 months to support the use of these older animals in routine preclinical toxicology studies. As the upper age range of Beagle dogs routinely used in toxicology studies does not normally exceed 24 months, there is an absence of appropriate age-matched historical control data. The generation of such data was crucial to understand whether age-related differences in spontaneous findings might confound the interpretation of toxicology study data. While the majority of the histopathology findings in all the older dogs occurred at a similar prevalence as those expected in young adult dogs (<24 months), a number of differences were observed in the thymus (involution), bone marrow (increased adiposity), testes (degenerative changes), and lung (fibrosis, pigment and alveolar hyperplasia) that could be misinterpreted as a test article effect. Minor differences in some clinical pathology values (hemoglobin, alkaline phosphatase, absolute reticulocytes) were of a small magnitude and considered unlikely to affect the interpretation of study data.

Glasgow supported self-management trial (GSuST) for patients with moderate to severe COPD: randomised controlled trial

OBJECTIVE

To determine whether supported self management in chronic obstructive pulmonary disease (COPD) can reduce hospital readmissions in the United Kingdom.

DESIGN

Randomised controlled trial.

SETTING

Community based intervention in the west of Scotland.

PARTICIPANTS

Patients admitted to hospital with acute exacerbation of COPD.

INTERVENTION

Participants in the intervention group were trained to detect and treat exacerbations promptly, with ongoing support for 12 months.

MAIN OUTCOME MEASURES

The primary outcome was hospital readmissions and deaths due to COPD assessed by record linkage of Scottish Morbidity Records; health related quality of life measures were secondary outcomes.

RESULTS

464 patients were randomised, stratified by age, sex, per cent predicted forced expiratory volume in 1 second, recent pulmonary rehabilitation attendance, smoking status, deprivation category of area of residence, and previous COPD admissions. No difference was found in COPD admissions or death (111/232 (48%) v 108/232 (47%); hazard ratio 1.05, 95% confidence interval 0.80 to 1.38). Return of health related quality of life questionnaires was poor (n=265; 57%), so that no useful conclusions could be made from these data. Pre-planned subgroup analysis showed no differential benefit in the primary outcome relating to disease severity or demographic variables. In an exploratory analysis, 42% (75/150) of patients in the intervention group were classified as successful self managers at study exit, from review of appropriateness of use of self management therapy. Predictors of successful self management on stepwise regression were younger age (P=0.012) and living with others (P=0.010). COPD readmissions/deaths were reduced in successful self managers compared with unsuccessful self managers (20/75 (27%) v 51/105 (49%); hazard ratio 0.44, 0.25 to 0.76; P=0.003).

CONCLUSION

Supported self management had no effect on time to first readmission or death with COPD. Exploratory subgroup analysis identified a minority of participants who learnt to self manage; this group had a significantly reduced risk of COPD readmission, were younger, and were more likely to be living with others.

[Somatic tinnitus (review). A consequence of plasticity and bimodal integration in the dorsal cochlear nucleus]

Somatic tinnitus is a peculiar tinnitus type that can be defined as a tinnitus that can be modulated in intensity and/or pitch by manipulating some regions of the head and neck but also as tinnitus associated with facial pain or dysesthesis in the same area. Those areas are innervated by the trigeminal nerve and the cervical plexus. This can be explained by functional connections between the trigeminal system and the auditory brainstem and mid-brain. A literature overview shows how different messages coming from the head and neck are able to modulate the hearing information. Tinnitus is generated by an increase of the spontaneous discharges of the dorsal cochlear nucleus neurons, tonotopic reorganisation and an increase of the neural synchronism in the auditory cortex. Trigeminal stimulations have an influence on the activity of the dorsal cochlear nucleus especially in case of an associated hearing loss.

Improving medical students' attitudes towards the chronic sick: a role for social science research

BACKGROUND

Many medical students are negatively disposed toward the elderly and chronic sick. The present study assessed the impact of a community-based teaching initiative, the Life History Project, on students' attitudes to these groups.

METHODS

A questionnaire including Likert based responses and free text comments was distributed to all first-year MBChB students after completion of their Life History coursework. Data was analysed using SPSS and content analysis.

RESULTS

A high proportion of students believed the Life History Project had increased their understanding of both psychological and social aspects of health and illness and the role of the humanistic social sciences within this. We discovered that the Life History Project not only gave students first-hand experience of the elderly and chronic sick but also had a positive effect on their attitudes towards these groups. The qualitative free text comments corroborated these views.

CONCLUSIONS

It is possible to positively influence medical students' attitudes towards these stigmatised groups; it is therefore important that we continue to enhance opportunities for learning about the impact of chronic illness on individuals and society throughout the curriculum.

The use of a modification of the Patient Enablement Instrument in asthma

AIM

To ascertain if the Patient Enablement Instrument (PEI) could be adapted for use in asthma management, and to use it to evaluate "enablement" in patients with asthma randomised to either a fixed or adjustable medication dosing regime.

METHODS

The original Patient Enablement Instrument was modified by making a minor change to the opening statement. 228 adults with asthma from 72 UK general practices were recruited to the study. The internal and external consistencies of the modified PEI were assessed. Individual scores were compared across treatment groups.

RESULTS

The modified PEI had high internal consistency. There was a significant correlation between modified PEI total score and change in Mini Asthma Quality of Life Questionnaire. A significantly greater proportion of patients using adjustable medication dosing had a clinically relevant treatment benefit.

CONCLUSIONS

The Patient Enablement Instrument can be used to measure "enablement" in asthma.

Widespread endoscopic mucosal resection of the esophagus with strategies for stricture prevention: a preclinical study

BACKGROUND AND STUDY AIMS

Circumferential endoscopic mucosal resection of the esophagus is complicated by stricture formation. Prophylactic measures for avoiding such strictures have not been well studied. The aim of this preclinical study was to assess strategies for prevention of esophageal strictures in a porcine model following widespread endoscopic mucosal resection (EMR).

METHODS

A total of 18 60-kg pigs were included in the study. The roles of strip width (group 1), prophylactic steroids (group 2), and prophylactic stents (group 3) in the prevention of post-mucosectomy strictures were studied. Six animals were included in each group. Esophageal mucosal resection was achieved using a novel widespread EMR technique previously described by our group. Animals in group 1 underwent partial (50% circumference) mucosal resection without prophylactic measures, while animals in the other two groups underwent circumferential mucosal resection. Animals in group 2 received 80 mg of triamcinolone injected directly into the exposed submucosal tissue (20 mg injection in four quadrants). Animals in group 3 received esophageal metal stents coated with small-intestine submucosa (SIS) that were deployed immediately post-resection. Animals were kept alive for 1 month.

RESULTS

Partial and circumferential widespread EMRs were achieved in all animals. There were no procedural complications. Repeat endoscopy at 1 month showed no strictures in group 1. Only four animals were studied in group 2, owing to the high complication rate (periesophageal abscess in all animals) with one early death. Three of the surviving animals developed mild to tight strictures. In group 3, all animals developed tight strictures; however, there was early stent migration in four animals and premature stent removal in two animals because of persistent vomiting.

CONCLUSIONS

Partial widespread EMR of the esophagus heals without stricture formation and does not require prophylactic intervention. The use of deep mural steroid injection following a circumferential resection does not appear to prevent strictures and may result in serious adverse events. Short-term use of esophageal stents is inadequate for stricture prevention. However, better results may be anticipated with longer term (at least 6 weeks) stent use.

Characterization of a SNF1 homologue from the phytopathogenic fungus Sclerotinia sclerotiorum

In yeast, the SNF1 gene product is essential for the release of catabolic repression. We report the isolation and characterization of an SNF1 homologue from the necrotrophic pathogen Sclerotinia sclerotiorum. Ss snf1 encodes a 765-amino-acid protein in which the catalytic domain has an overall identity with the yeast proteins varying from 55 to 76% while the C-terminal half of Ss SNF1 has a weak homology of about 20% with the yeast sequences. Reverse transcription-polymerase chain reaction showed that its transcripts were weakly and constitutively expressed in planta and in vitro regardless of the nature of the carbon sources and of the presence or absence of glucose. Expression of Ss snf1 in yeast cells allowed the snf1 mutant cells to utilize sucrose, raffinose or glycerol for growth while expression of the Ss snf1 catalytic domain did not restore growth on raffinose or glycerol. Ss SNF1 is structurally homologous to Snf1p, suggesting that the interactions between the kinase and the accessory subunits to activate the enzymatic complex are conserved in fungi.

Expression and compartmentation of the glucose repressor CRE1 from the phytopathogenic fungus Sclerotinia sclerotiorum

The glucose repressor from the phytopathogenic fungus Sclerotinia sclerotiorum is encoded by the cre1 gene. Polyclonal antibodies were raised against a fusion protein (gluthathione S-transferase) GST-CRE1 in order to study cre1 expression. Western blot analyses revealed that CRE1 synthesis is regulated by the nature of the extracellular carbon source. High CRE1 levels are induced by glucose and remain stable after transfer into pectin medium, suggesting the existence of post-translational mechanisms which inactivate CRE1 to allow transcription of glucose-repressed genes. Subcellular fractionation demonstrated that CRE1 is localized in the nuclei of glucose grown hyphae and in the cytoplasm when glucose is removed from the culture medium. CRE1 fused to green fluorescent protein (GFP) was introduced into Aspergillus nidulans. Fluorescence microscopy showed the nuclear localization of the GFP-CRE1 fusion protein according to the presence of glucose in the culture medium, suggesting homologous post-translational regulations of glucose repressors in fungi. We propose that filamentous fungi regulate the activity of the glucose repressor by controlling its nuclear translocation.

The glucose repressor CRE1 from Sclerotinia sclerotiorum is functionally related to CREA from Aspergillus nidulans but not to the Mig proteins from Saccharomyces cerevisiae

We isolated the putative glucose repressor gene cre1 from the phytopathogenic fungus Sclerotinia sclerotiorum. cre1 encodes a 429 amino acid protein 59% similar to the carbon catabolite repressor CREA from Aspergillus nidulans. In addition to the overall amino acid sequence relatedness between CRE1 and CREA proteins, cre1 can functionally complement the A. nidulans creAd30 mutation as assessed by repression of the alcohol dehydrogenase I gene expression. The CREI region carrying the two zinc fingers is also very similar to the DNA binding domains of the Saccharomyces cerevisiae glucose repressors Mig1p and Mig2p. Despite the presence in the CRE1 protein of several motifs involved in the regulation of Miglp activity, cre1 cannot complement mig deficiencies in S. cerevisiae. These data suggest that glucose repression pathways may have evolved differently in yeasts and filamentous fungi.

Pancreatic sphincter hypertension increases the risk of post-ERCP pancreatitis

BACKGROUND AND STUDY AIMS

The reason for the increased risk of pancreatitis after endoscopic retrograde cholangiopancreatography (ERCP) in patients with sphincter of Oddi dysfunction is not known. This study sought to determine whether pancreatic sphincter hypertension might explain some of the increased risk.

PATIENTS AND METHODS

The incidence of pancreatitis was determined from a cohort of patients who underwent pancreatic sphincter manometry. Additional data collected included: pancreatic and biliary sphincter manometry results, distal bile duct diameter, chronic pancreatitis grade by pancreatography, and endoscopic treatments.

RESULTS

Ten of 32 patients (31%) with pancreatic sphincter hypertension developed post-ERCP pancreatitis, compared to one of 33 (3%) with normal pancreatic manometry (P = 0.002). Patients with pancreatic sphincter hypertension were more likely to undergo endoscopic treatments (88%) compared to those with normal manometry (27%) (P = 0.001). The distal bile duct diameter was significantly smaller (4.5 +/- 0.5 mm) in patients who developed post-ERCP pancreatitis than in those who did not (6.2 +/- 0.3) (P = 0.025). Patients with small distal bile duct diameters (< 5 mm) were three times more likely to develop post-ERCP pancreatitis than those with larger ducts (relative risk [RR] 3.1, 95% confidence interval [CI] 0.9, 10.7). Patients with pancreatic sphincter hypertension were ten times more likely to develop post-ERCP pancreatitis than those with normal pancreatic manometry (RR 10.3, 95% CI 1.5, 76.0). In patients with a small bile duct size, pancreatic sphincter hypertension substantially increased the risk compared to those with normal manometry (RR 18.1, 95% CI 1.1, 287.6).

CONCLUSIONS

Pancreatic sphincter hypertension greatly increases the risk of post-ERCP pancreatitis in patients undergoing treatment or evaluation, or both, for sphincter of Oddi dysfunction.
