The association between medical spending and health status: A study of selected African countries.

Background: The report from the World Health Organization (WHO) reveals that health spending worldwide remains highly unequal as more than 80% of the world's population live in low and middle-income countries but only account for about 20% of global health expenditure. Another report by the WHO on the state of health financing in Africa published in 2013 intimates that countries that are part of their member states are still on the average level in meeting set goals in financing key health projects. Objective: The study set out to investigate the association between public and private spending and health status for eight selected African countries, namely Burundi, Eritrea, Ethiopia, Kenya, Rwanda, Sudan, Tanzania and Uganda. Health status indicators include the incidence of tuberculosis, mortality rates, maternal deaths and prevalence of HIV. Methods: Descriptive statistics and pairwise correlation are used to assess the relationship between healthcare spending and health status. Random and fixed effect models are further employed to provide insights into the association between descriptive statistics and pairwise correlation. We used annual data from the year 2000 to 2014 obtained from world development indicators. Results: The relationship between healthcare spending (public and private) and health status is statistically significant. Public healthcare expenditure has a higher association than private expenditure in reducing the mortality rate, tuberculosis and HIV for the average country in our sample. For example, an increase in public healthcare spending is negatively associated and statistically significant at 5% or better in reducing female mortality, male mortality, tuberculosis and HIV. Private healthcare spending is more impactful in the area of maternal deaths, where it is associated negatively and statistically significant at 1%. An increase in private healthcare spending is linked to a reduction in maternal deaths. We also compared the association between an increase in healthcare spending on males versus females and observed that public health expenditure impacts the health status of both sexes equally, however, private health expenditure provides a greater positive benefit to males. It is worth remembering that two goals of the United Nations agenda on sustainable development are gender equality and ensuring healthcare for all. Conclusion: The findings of this research call for the selected African countries to pay more attention to public healthcare expenditure in order to improve health status, especially since private healthcare which provides access to healthcare facilities for some poor people leads to costs that are a burden. So, future research should focus on analyzing components of private healthcare spending such as direct household out-of-pocket spending, private insurance and direct service payments by private corporations as dependent variables to understand what form of private investment should be encouraged.

National Survey of US HIV Clinicians: Knowledge and Attitudes About the Affordable Care Act and Opinions of its Impact on Quality of Care and Barriers to Care.

BACKGROUND: The Affordable Care Act's (ACA's) major reforms started in 2014. In addition to assessing HIV clinicians' ACA knowledge and attitudes, this study aims to evaluate HIV clinicians' perspectives on whether the ACA has impacted the quality of HIV care and whether it addresses the main barriers to HIV care. METHODS: HIV clinicians were emailed a survey weblink in 2018. Descriptive statistics, Mann-Whitney U tests, and binary logistic regression were performed. RESULTS: Of the 211 survey participants, the majority (70%) answered all 4 knowledge questions correctly. About 80% knew correctly whether their state had expanded Medicaid. Participants from Medicaid expansion states were more likely to report an improved ability to provide high-quality care compared with participants from Medicaid nonexpansion states (50% vs 34%; P = .01). The average response to whether the ACA addresses the main barriers to HIV care was neutral and did not differ based on Medicaid status. The top 3 main barriers to HIV care cited were mental health, substance use, and transportation. CONCLUSIONS: HIV clinicians in Medicaid expansion states were more likely to report an improved ability to provide high-quality care since ACA implementation compared with those in Medicaid nonexpansion states. However, HIV clinicians across the United States are concerned that the ACA does not address the main barriers to HIV care. To be successful, the "Ending the HIV Epidemic" initiative should address these identified barriers.

The ideal technique for processing SpyBite tissue specimens: a prospective, single-blinded, pilot-study of histology and cytology techniques.

Background and study aims Diagnostic sensitivity for indeterminate biliary lesions remains suboptimal. Cytology techniques may mitigate the impediment of small cholangioscopic specimens. Our primary aim was to compare cell block cytology (CB) with standard histology for foregut SpyBite (SB) specimens. Our secondary aim was to assess CB in biliary SB biopsies. Patients and methods This was a two-phase prospective pilot study. In phase one, a prospective pilot study, foregut SB specimens from three sites (4 per site per patient per processing technique) were allocated to CB or histology, and assessed by a single, blinded pathologist. The gold standard comprised two standard forceps (CFB) histological specimens per site per patient. Specimen ease of processing, size and number, adequacy for diagnosis and artefact were evaluated. In phase two, CB was used for consecutive patients with indeterminate biliary lesions, and compared with phase one CB results. Results In phase one, 240 SB foregut biopsies were performed in 10 patients, 227 specimens recorded by pathologist. Specimen origin was identified in 100 % and 97 % of histology and CB batches respectively. Specimens were significantly larger in the histology group (2.02 mm vs 1.49 mm, P  < 0.05). There was a trend to less crush artifact with CB, and no difference in processing difficulty. In phase two, 11 patients (63.0 ±12.7 years, 91 % female) underwent SpyGlass (SG) assessment of suspected indeterminate stricture (n = 8) or mass (n = 3), and six underwent SB. All CB specimens were adequate for diagnosis. Specimen parameters were not significantly different from luminal CB outcomes. Conclusions In this pilot study, cell block cytology showed similar results as histological analysis of SpyBite specimens in the analysis of biliary stricture.

Modified UCN2 Peptide Acts as an Insulin Sensitizer in Skeletal Muscle of Obese Mice.

The neuropeptide urocortin 2 (UCN2) and its receptor corticotropin-releasing hormone receptor 2 (CRHR2) are highly expressed in skeletal muscle and play a role in regulating energy balance and glucose metabolism. We investigated a modified UCN2 peptide as a potential therapeutic agent for the treatment of obesity and insulin resistance, with a specific focus on skeletal muscle. High-fat-fed mice (C57BL/6J) were injected daily with a PEGylated UCN2 peptide (compound A) at 0.3 mg/kg subcutaneously for 14 days. Compound A reduced body weight, food intake, whole-body fat mass, and intramuscular triglycerides compared with vehicle-treated controls. Furthermore, whole-body glucose tolerance was improved by compound A treatment, with increased insulin-stimulated Akt phosphorylation at Ser473 and Thr308 in skeletal muscle, concomitant with increased glucose transport into extensor digitorum longus and gastrocnemius muscle. Mechanistically, this is linked to a direct effect on skeletal muscle because ex vivo exposure of soleus muscle from chow-fed lean mice to compound A increased glucose transport and insulin signaling. Moreover, exposure of GLUT4-Myc-labeled L6 myoblasts to compound A increased GLUT4 trafficking. Our results demonstrate that modified UCN2 peptides may be efficacious in the treatment of type 2 diabetes by acting as an insulin sensitizer in skeletal muscle.

First Presentation Acute Rheumatic Fever is Preventable in a Community Setting: A School-based Intervention.

BACKGROUND: Robust evidence is lacking for community initiatives to prevent first presentation acute rheumatic fever (ARF) by group A streptococcal (GAS) pharyngitis treatment. METHODS: We measured the effect of introducing a sore throat clinic program on first presentation ARF into 61-year 1-8 schools with students 5-13 years of age (population ≈25,000) in Auckland, New Zealand. The study period was 2010-2016. A generalized linear mixed model investigated ARF rate changes before and after the staggered introduction of school clinics. Nurses and lay workers treated culture-proven GAS sore throats (including siblings) with 10 days of amoxicillin. ARF cases were identified from a population-based secondary prophylaxis register. Annual pharyngeal GAS prevalence was assessed in a subset. RESULTS: ARF rates in 5-13 year olds dropped from 88 [95% confidence interval (CI): 79-111] per 100,000 preclinics to 37 (95% CI: 15-83) per 100,000 after 2 years of clinic availability, a 58% reduction. No change in rate was demonstrated before the introduction of clinics [P = 0.88; incidence risk ratio for a 1-year change: 0.98 (95% CI: 0.63-1.52)], but there was a significant decrease of first presentation ARF rates with time after the introduction of the sore throat program [P = 0.008; incidence risk ratio: 0.61 (95% CI: 0.43-0.88)]. Pharyngeal GAS cross-sectional prevalence fell from 22.4% (16.5-30.5) preintervention to 11.9% (8.6-16.5) and 11.4% (8.2-15.7) 1 or 2 years later (P = 0.005). CONCLUSIONS: ARF declined significantly after school-based GAS pharyngitis management using oral amoxicillin paralleled by a decline in pharyngeal GAS prevalence.

Nurse-led school-based clinics for rheumatic fever prevention and skin infection management: evaluation of Mana Kidz programme in Counties Manukau.

AIM: To evaluate registered nurse-led school clinics in 61 primary and intermediate schools in Counties Manukau. METHODS: The evaluation (conducted August­December, 2014) collated evidence concerning service delivery, outcomes, value for money and effectiveness. RESULTS: 97% (23,756/24,497) of eligible children were consented, 11% (20,696/191,423) of throat swabs taken (February 2013­September 2014) were culture positive for Group A Streptococcus (GAS); 20,176 were treated. Mana Kidz teams treated (includes cleaning and covering alone) 17,593 skin infections and actioned 4,178 school health referrals. A pre-programme cross sectional GAS pharyngeal prevalence demonstrated a relative risk 1.8 (1.3­2.3) (95%CI) of being pharyngeal GAS positive in 2013 compared to 2014. Hospitalisations for acute rheumatic fever (ARF) and skin infections for children aged 5­12 years living in Counties Manukau are declining and this appears to be temporally related to the introduction of the Mana Kidz programme. Effective engagement with children, parents/ whanau and improved health literacy was demonstrated, especially knowledge about sore throats, ARF, medication adherence and skin infection. The programme was delivered at $280 per participating child in the 2013/14 financial year. CONCLUSION: Mana Kidz is an effective programme with a substantial contribution to health care for children, aged 5­12 years, identified at increased risk of poor health outcomes.

Comparison of illumigene Group A Streptococcus Assay with Culture of Throat Swabs from Children with Sore Throats in the New Zealand School-Based Rheumatic Fever Prevention Program.

Group A streptococcal (GAS) pharyngitis is a particularly important condition in areas of New Zealand where the incidence of acute rheumatic fever remains unacceptably high. Prompt diagnosis and treatment of GAS pharyngitis are cornerstones of the Rheumatic Fever Prevention Programme, but these are hindered by the turnaround time of culture. Tests with excellent performance and rapid turnaround times are needed. For this study, throat swabs (Copan ESwabs) were collected from schoolchildren self-identifying with a sore throat. Samples were tested by routine culture and the illumigene GAS assay using loop-mediated isothermal amplification. Discrepant results were resolved by retesting of the same specimen by an alternative molecular assay. Seven hundred fifty-seven throat swab specimens were tested by both methods. The performance characteristics of the illumigene assay using culture on blood agar as the "gold standard" and following discrepancy analysis were as follows: sensitivity, 82% and 87%, respectively; specificity, 93% and 98%, respectively; positive predictive value, 61% and 88%, respectively; and negative predictive value, 97% and 97%, respectively. In our unique setting of a school-based throat swabbing program, the illumigene assay did not perform quite as well as described in previous reports. Despite this, its improved sensitivity and rapid turnaround time compared with those of culture are appealing.

Intragenomic Conflict over Dispersal.

Intragenomic conflict may arise when social partners are more related through one parent than the other-for example, owing to individuals or gametes of one sex dispersing further prior to fertilization. In particular, genes originating from the former parent are favored to promote selflessness, and those originating from the latter parent are favored to promote selfishness. While the impact of patterns of dispersal on the evolution of intragenomic conflict has received recent attention, the consequences of intragenomic conflict for the evolution of dispersal remain to be explored. We suggest that if the evolution of dispersal is driven at least in part by kin selection, differential relatedness of social partners via their mothers versus their fathers may lead to an intragenomic conflict, with maternal-origin genes and paternal-origin genes favoring different rates of dispersal. As an illustration, we extend a classic model of the evolution of dispersal to explore how intragenomic conflict may arise between an individual's maternal-origin and paternal-origin genes over whether that individual should disperse in order to ease kin competition. Our analysis reveals extensive potential for intragenomic conflict over dispersal and predicts that genes underpinning dispersal phenotypes may exhibit parent-of-origin-specific expression, which may facilitate their discovery.

Registered nurse assessment and treatment of skin sepsis in New Zealand schools: the development of protocols.

BACKGROUND: Skin infection is the commonest medical cause of hospitalisation in school children. Disadvantaged children, usually Maori or Pacific, have high rates of preventable diseases. AIM: To improve access to early treatment for skin infections using nurse-led school clinics in South Auckland, including provision of antibiotics under delegated standing orders. METHOD: Evidence-based protocols for the recognition and treatment of skin sepsis were developed following a literature search. A training package was developed for health professionals involved and outcome data were collected from a pilot study in which the protocols were trialled. RESULTS: An algorithm for diagnosis of skin infections was adapted from Steer et al (Bull World Health Organ. 2009;87:173-9). Fusidic acid ointment was recommended as first-line treatment for localised impetigo. Twice daily oral cephalexin was recommended for extensive impetigo and cellulitis, for palatability and simplicity of dosing. Fifty-six episodes of skin infection received treatment under standing orders in the first 15 weeks of the pilot study. CONCLUSION: Robust evidence to determine optimal choice, dosage and duration of antibiotic therapy for skin sepsis in children is lacking. The algorithms described are consistent with available evidence and provide a pragmatic approach for use in registered nurse (RN)-led school clinics.

Nurse-led school-based clinics for skin infections and rheumatic fever prevention: results from a pilot study in South Auckland.

AIM: To assess the acceptability and feasibility of delivering targeted primary health care in a decile one primary school setting. METHOD: A pilot public health nurse (PHN)-led clinic was set up in a South Auckland primary school (roll approximately 400). The clinic was based on a previous sore throat clinic model with modifications aimed at improving programme feasibility and effectiveness. The timely identification and treatment of Group A Streptococcal (GAS) throat infections to prevent rheumatic fever (RF), and the prevention and treatment of four skin infections (cellulitis, impetigo, infected eczema and scabies) were the focus. The pilot ran for 15 weeks from April to July 2011. Evaluation included documentation review, key school and healthcare stakeholder interviews and parent questionnaires. RESULTS: The consent rate was 92.2%. Of a total 722 throat swabs taken from 337 students, 94 were GAS positive. Ninety-eight assessments of skin conditions were completed at which 76 had a skin infection diagnosed, the most common infection being impetigo (n=46). Thirty-one skin infections were diagnosed in the first week of the pilot. PHN workload was high with a total of 539 phone calls, 137 home visits and 51 school-based parent consultations. The approach was highly acceptable to the majority of key stakeholders. Extrapolating pilot costs results in an estimated annual cost of $510 per student for the programme. CONCLUSION: It is likely to be both acceptable and feasible to take this model of delivering targeted primary health care to school aged children and use it on a larger scale. The complexity of providing this type of service should not be underestimated and it is essential that robust processes are in place to ensure smooth, safe running of such a programme. Long-term outcome evaluation will be vital to assess programme effectiveness.

Measuring faculty retention and success in academic medicine.

PURPOSE: To develop and demonstrate the usefulness of quantitative methods for assessing retention and academic success of junior faculty in academic medicine. METHOD: The authors created matched sets of participants and nonparticipants in a junior faculty development program based on hire date and academic series for newly hired assistant professors at the University of California, San Diego (UCSD), School of Medicine between 1988 and 2005. They used Kaplan-Meier and Cox proportional hazards survival analyses to characterize the influence of covariates, including gender, ethnicity, and program participation, on retention. They also developed a new method for quantifying academic success based on several measures including (1) leadership and professional activities, (2) honors and awards, (3) research grants, (4) teaching and mentoring/advising activities, and (5) publications. The authors then used these measures to compare matched pairs of participating and nonparticipating faculty who were subsequently promoted and remained at UCSD. RESULTS: Compared with matched nonparticipants, the retention of junior faculty who participated in the faculty development program was significantly higher. Among those who were promoted and remained at UCSD, the academic success of faculty development participants was consistently greater than that of matched nonparticipants. This difference reached statistical significance for leadership and professional activities. CONCLUSIONS: Using better quantitative methods for evaluating retention and academic success will improve understanding and research in these areas. In this study, use of such methods indicated that organized junior faculty development programs have positive effects on faculty retention and may facilitate success in academic medicine.

Improving the discharge process by embedding a discharge facilitator in a resident team.

BACKGROUND: Hospital discharges are vulnerable periods for patient safety, especially in teaching hospitals where discharges are done by residents with competing demands. We sought to assess whether embedding a nurse practitioner on a medical team to help physicians with the discharge process would improve communication, patient follow-up, and hospital reutilization. METHODS: A 5-month randomized controlled trial was conducted on the medical service at an academic tertiary-care hospital. A nurse practitioner was randomly assigned to 1 resident team to complete discharge paperwork, arrange follow-up appointments and prescriptions, communicate discharge plans with nursing and primary care physicians, and answer questions from discharged patients. RESULTS: Intervention patients had more discharge summaries completed within 24 hours (67% vs. 47%, P < 0.001). Similarly, they had more follow-up appointments scheduled by the time of discharge (62% vs. 36%, P < 0.0001) and attended those appointments more often within 2 weeks (36% vs. 23%, P < 0.0002). Intervention patients knew whom to call with questions (95% vs. 85%, P = 0.003) and were more satisfied with the discharge process (97% vs. 76%, P < 0.0001). Attending rounds on the intervention team finished on time (45% vs. 31%, P = 0.058), and residents signed out on average 46 minutes earlier each day. There was no significant difference between the groups in 30-day emergency department visits or readmissions. CONCLUSIONS: Helping resident physicians with the discharge process improves many aspects of discharge communication and patient follow-up, and saves residents' time, but had no effect on hospital reutilization for a general medicine population.

Proton pump inhibitors for prophylaxis of nosocomial upper gastrointestinal tract bleeding: effect of standardized guidelines on prescribing practice.

BACKGROUND: Proton pump inhibitors (PPIs) are frequently prescribed for prophylaxis of nosocomial upper gastrointestinal tract bleeding. Some inpatients receiving PPIs may have no risk factors for nosocomial upper gastrointestinal tract bleeding, and PPIs may be continued unnecessarily at hospital discharge. We aimed to assess the effect of standardized guidelines on PPI prescribing practices. METHODS: Guidelines for PPI use were implemented on the medical service at a tertiary center. We reviewed PPI use among inpatient admissions during the month before implementation of guidelines and then prospectively evaluated PPI use among admissions during the month after implementation of guidelines. RESULTS: Among an overall cohort of 942 patients, 48% were prescribed PPIs while inpatients, and 41% were prescribed PPIs at hospital discharge. Univariate predictors of inpatient PPI use included age, length of hospital stay, history of gastroesophageal reflux disease or upper gastrointestinal tract bleeding, and outpatient PPI, aspirin, or glucocorticoid use. Among patients not on an outpatient regimen of PPIs at admission, implementation of guidelines resulted in lower rates of inpatient PPI use (27% before vs 16% after, P = .001) and PPI prescription at discharge (16% before vs 10% after, P = .03). CONCLUSION: Introduction of standardized guidelines resulted in lower rates of PPI use among a subset of inpatients and reduced the rate of PPI prescriptions at discharge.

Description of a multifaceted rehabilitation program including overground gait training for a child with cerebral palsy: A case report.

This case describes the outcomes of a multifaceted rehabilitation program including body weight-supported overground gait training (BWSOGT) in a nonambulatory child with cerebral palsy (CP) and the impact of this treatment on the child's functional mobility. The patient is a nonambulatory 10-year-old female with CP who during an inpatient rehabilitation stay participated in direct, physical therapy 6 days per week for 5 weeks. Physical therapy interventions included stretching of her bilateral lower extremities, transfer training, bed mobility training, balance training, kinesiotaping, supported standing in a prone stander, two trials of partial weight-supported treadmill training, and for 4 weeks, three to five times per week, engaged in 30 minutes of BWSOGT using the Up n' go gait trainer, Lite Gait Walkable, and Rifton Pacer gait trainer. Following the multifaceted rehabilitation program, the patient demonstrated increased step initiation, increased weight bearing through bilateral lower extremities, improved bed mobility, and increased participation in transfers. The child's Gross Motor Functional Measure (GMFM) scores increased across four dimensions and her Physical Abilities and Mobility Scale (PAMS) increased significantly. This case report illustrates that a multifaceted rehabilitation program including BWSOGT was an effective intervention strategy to improve functional mobility in this nonambulatory child with CP.

School-based prevention of acute rheumatic fever: a group randomized trial in New Zealand.

BACKGROUND: Acute rheumatic fever (ARF) and its sequela, rheumatic heart disease is the commonest cause of childhood cardiac morbidity globally. The current approach to the prevention of a primary attack of rheumatic fever in children using oral medication for streptococcal pharyngitis is poorly supported. The efficacy of injectable penicillin, in high rheumatic fever incidence military environments is indisputable. OBJECTIVE: To evaluate school-based control of rheumatic fever in an endemic area. METHODS: Fifty-three schools ( approximately 22,000 students) from a rheumatic fever high incidence setting ( approximately 60/100,000) in Auckland, New Zealand were randomized. The control group received routine general practice care. The intervention was a school-based sore throat clinic program with free nurse-observed oral penicillin treatment of group A streptococcal pharyngitis. The outcome measure was ARF in any child attending a study school. Analysis A defined ARF cases using criteria derived from Jones Criteria 1965 (definite) and 1956 (probable) with more precise definitions. Analysis B was based on 1992 Jones criteria but also included echocardiography to determine definite cases. RESULTS: In Analysis A, 24 (55/100,000) cases occurred in clinic schools and 29 (67/100,000) in nonclinic schools, a 21% reduction when adjusted for demography and study design (P = 0.47). Analysis B revealed a 28% reduction 26 (59/100,000) and 33 (77/100,000) cases, respectively (P = 0.27). CONCLUSION: This study involving 86,874 person-years showed a nonsignificant reduction in the school-based sore throat clinic programs.
