Referral of children seeking care at private health facilities in Uganda.
BACKGROUND: In Uganda, referral of sick children seeking care at public health facilities is poor and widely reported. However, studies focusing on the private health sector are scanty. The main objective of this study was to assess referral practices for sick children seeking care at private health facilities in order to explore ways of improving treatment and referral of sick children in this sector. METHODS: A survey was conducted from August to October 2014 in Mukono district, central Uganda. Data was collected using a structured questionnaire supplemented by Focus Group Discussions and Key Informant interviews with private providers and community members. RESULTS: A total of 241 private health facilities were surveyed; 170 (70.5%) were registered drug shops, 59 (24.5%) private clinics and 12 (5.0%) pharmacies. Overall, 104/241 (43.2%) of the private health facilities reported that they had referred sick children to higher levels of care in the two weeks prior to the survey. The main constraints to follow referral advice as perceived by caretakers were: not appreciating the importance of referral, gender-related decision-making and negotiations at household level, poor quality of care at referral facilities, inadequate finances at household level; while the perception that referral leads to loss of prestige and profit was a major constraint to private providers. CONCLUSION: In conclusion, the results show that referral of sick children at private health facilities faces many challenges at provider, caretaker, household and community levels. Thus, interventions to address constraints to referral of sick children are urgently needed
Assessing the potential of rural and urban private facilities in implementing child health interventions in Mukono district, central Uganda-a cross sectional study.
BACKGROUND: Private facilities are the first place of care seeking for many sick children. Involving these facilities in child health interventions may provide opportunities to improve child welfare. The objective of this study was to assess the potential of rural and urban private facilities in diagnostic capabilities, operations and human resource in the management of malaria, pneumonia and diarrhoea. METHODS: A survey was conducted in pharmacies, private clinics and drug shops in Mukono district in October 2014. An assessment was done on availability of diagnostic equipment for malaria, record keeping, essential drugs for the treatment of malaria, pneumonia and diarrhoea; the sex, level of education, professional and in-service training of the persons found attending to patients in these facilities. A comparison was made between urban and rural facilities. Univariate and bivariate analysis was done. RESULTS: A total of 241 private facilities were assessed with only 47 (19.5 %) being in rural areas. Compared to urban areas, rural private facilities were more likely to be drug shops (OR 2.80; 95 % CI 1.23-7.11), less likely to be registered (OR 0.31; 95 % CI 0.16-0.60), not have trained clinicians, less likely to have people with tertiary education (OR 0.34; 95 % CI 0.17-0.66) and less likely to have zinc tablets (OR 0.38; 95 % CI 0.19-0.78). In both urban and rural areas, there was low usage of stock cards and patient registers. About half of the facilities in both rural and urban areas attended to at least one sick child in the week prior to the interview. CONCLUSION: There were big gaps between rural and urban private facilities with rural ones having less trained personnel and less zinc tablets' availability. In both rural and urban areas, record keeping was low. Child health interventions need to build capacity of private facilities with special focus on rural areas where child mortality is higher and capacity of facilities lower
Prescription for antibiotics at drug shops and strategies to improve quality of care and patient safety: a cross-sectional survey in the private sector in Uganda.
OBJECTIVES: The main objective of this study was to assess practices of antibiotic prescription at registered drug shops with a focus on upper respiratory tract infections among children in order to provide data for policy discussions aimed at improving quality of care and patient safety in the private health sector in Uganda. METHODS: A survey was conducted within 57 parishes from August to October 2014 in Mukono District, Uganda. Data was captured on the following variables: drug shop characteristics, training of staff in management of pneumonia, availability of guidelines and basic equipment, available antibiotics, knowledge on treatment of pneumonia in children aged <5 years. The main study outcome was the proportion of private health facilities prescribing an antibiotic. RESULTS: A total of 170 registered drug shops were surveyed between August and October 2014. The majority of drug shops, 93.5% were prescribing antibiotics, especially amoxicillin and trimethoprim-sulfamethoxazole (septrin). The professional qualification of a provider was significantly associated with this practice, p=0.04; where lower cadre staff (nursing assistants and enrolled nurses) overprescribed antibiotics. A third, 29.4% of drug shop providers reported that antibiotics were the first-line treatment for children with diarrhoea; yet the standard guideline is to give oral rehydration salts and zinc tablets. Only few providers, 8.2%, had training on antibiotics, with 10.6% on pneumonia case management. Further to this, 7.1% drug shops had WHO-Integrated Management of Childhood Illness guidelines, and a negligible proportion (<1%) had respiratory timers and baby weighing scales. Although the majority of providers, 82.4%, knew severe signs and symptoms of pneumonia, few, 17.6%, knew that amoxicillin was the first-line drug for treatment of pneumonia in children according to the guidelines. CONCLUSIONS: There is urgent need to regulate drug shop practices of prescribing and selling antibiotics, for the safety of patients seeking care at these outlets
Treatment and prevention of malaria in pregnancy in the private health sector in Uganda: implications for patient safety.
BACKGROUND: Malaria in pregnancy is a major public health problem in Uganda; and it is the leading cause of anaemia among pregnant women and low birth weight in infants. Previous studies have noted poor quality of care in the private sector. Thus there is need to explore ways of improving quality of care in the private sector that provides almost a half of health services in Uganda. METHODS: A survey was conducted from August to October 2014 within 57 parishes in Mukono district, central Uganda. The selected parishes had a minimum of 200 households and at least one registered drug shop, pharmacy or private clinic. Data was collected using a structured questionnaire targeting one provider who was found on duty in each selected private health facility and consented to the study. The main variables were: provider characteristics, previous training received, type of drugs stocked, treatment and prevention practices for malaria among pregnant women. The main study outcome was the proportion of private health facilities who prescribe treatment of fever among pregnant women as recommended in the guidelines. RESULTS: A total of 241 private health facilities were surveyed; 70.5 % were registered drug shops, 24.5 % private clinics and 5.0 % pharmacies. Treatment of fever among pregnant women in accordance with the national treatment guidelines was poor: 40.7 % in private clinics, decreasing to 28.2 % in drug shops and 16.7 % at pharmacies. Anti-malarial monotherapies sulphadoxine-pyrimethamine and quinine were commonly prescribed, often without consideration of gestational age. The majority of providers (>75 %) at all private facilities prescribed SP for intermittent preventive treatment but artemisinin-based combination therapy was prescribed: 8.3, 6.9 and 8.3 % respectively at drug shops, private clinics and pharmacies for prevention of malaria in pregnancy. Few facilities had malaria treatment guidelines; (44.1 % of private clinics, 17.9 % of drug shops, and 41.7 % at pharmacies. Knowledge of people at risk of malaria, P = 0.02 and availability of malaria treatment guidelines, P = 0.03 were the factors that most influenced correct treatment of fever in pregnancy. CONCLUSION: Treatment of fever during pregnancy was poor in this study setting. These data highlight the need to develop interventions to improve patient safety and quality of care for pregnant women in the private health sector in Uganda
Treatment of Sick Children Seeking Care in the Private Health Sector in Uganda: A Cluster Randomized Trial.
The main objective of this study was to assess whether training of private health providers and community sensitization on the importance of effective prompt care seeking and the need for referral could improve treatment of sick children in the private health sector in Uganda. Private providers were trained to diagnose and treat sick children according to the integrated community case management (iCCM) guidelines. In the control arm, routine services were offered. The outcomes were seeking care within 24 hours of onset of symptoms and appropriate case management for malaria, pneumonia, and diarrhea among children aged 40 breaths/minute, 1,596 (85.1%) in the intervention arm versus 104 (54.5%) in the control arm were given amoxicillin (P = 0.01). In conclusion, the intervention improved treatment of malaria, pneumonia, and diarrhea because of provider adherence to treatment guidelines. The policy implications of these findings are to initiate a dialogue at district and national levels on how to scale up the intervention in the private sector.

Osteoprotegerin antibodies in the pathogenesis of osteoporosis
Osteoporosis is a common complication of many autoimmune diseases that is
typically attributed to disease specific factors rather than a direct autoimmune
process. This thesis arises from the investigation of a patient with severe high bone
turnover osteoporosis who was identified as having autoimmune disease but whose
osteoporosis deteriorated despite appropriate treatment. This presentation led to the
hypothesis that neutralising autoantibodies to the bone protective cytokine
osteoprotegerin (OPG) may have developed.
Serum from the index patient, but not healthy controls, was able to
immunoprecipitate recombinant OPG protein, demonstrating that OPG had become
the target of an autoimmune response. Purified immunoglobulins from the index case
were able to inhibit the function of OPG in vitro, by suppressing OPG-mediated
inhibition of a luciferase reporter cell line. This represents the first description of
disease associated with neutralising antibodies to OPG. Whilst the
immunoprecipitation assay did identify OPG antibodies in further patients these
results were difficult to quantify. A more robust enzyme linked immunosorbent
assay for OPG antibodies was developed using OPG as a capture antigen, which
allowed the screening of patient cohorts. Presence of OPG antibodies was defined as
a titre greater than the mean plus three standard deviations of 101 healthy volunteers.
A low prevalence of 14/864 (1.6%) was seen in a general population cohort and no
association with bone density or turnover was seen. An association with higher
vascular calcification score in this cohort requires replication. A prevalence of
37/315 (11.7%) was seen in an osteoporosis cohort though no association was seen
with bone density or response to treatment. In a coeliac cohort OPG antibodies were
identified in 14/282 (5.0%) patients and presence of antibody was independently
associated with reduced spine bone density. Functional inhibition of OPG was shown
in vitro in 3/14 (21.4%) of the positive cases. Case finding of osteoporosis in the
coeliac cohort was not improved by identification of OPG antibodies. These results
are consistent with OPG antibodies being pathological in a small number of patients
with osteoporosis but a clinical utility of measuring OPG antibodies has not been
established
Assessing the potential of rural and urban private facilities in implementing child health interventions in Mukono district, central Uganda–a cross sectional study
Antiretroviral Resistance in Viral Isolates from HIV-1-transmitting Mothers and Their Infants
OBJECTIVE: To characterize concordance of resistance mutations to antiretroviral drugs (ART) in mother-infant pairs. DESIGN: Case series of HIV-transmitting mothers and infants in the Women and Infants Transmission Study, where delivery occurred between April 1994 and December 1999.
METHODS: Reverse transcriptase and protease genes were sequenced in stored viral isolates from 32 mother-infant pairs. Mutations were coded as pure mutants where only mutant virus was detected or as mixtures where a mixed mutant/wild-type population was identified. ART resistance mutations were compared for concordance between mothers and their infants.
RESULTS: Maternal mutations associated with resistance to nucleoside reverse transcriptase inhibitor (NRTI) and minor protease inhibitor (PI) drugs were typically concordant with that of infant, while those associated with non-nucleoside reverse transcriptase inhibitors (NNRTI) and major PI drugs were not. Of five NRTI-associated maternal mutations observed, three pure mutants corresponded with mutant in the infant, while two wild-type-predominant mixtures corresponded with infant wild type. The only NNRTI-associated mutation observed, K103N, was not transmitted, nor were the two major PI-associated mutations, L90M and V82I/V. Transmission of minor PI-associated mutations was consistent with the sole observed or dominant variant for 20 of 21 mutations.
CONCLUSIONS: For NRTI- and minor PI-associated mutations, transmission was consistent with relative quantity of variants in maternal virus. However, where NNRTI- and major PI-associated mutations were present in three cases, they were not transmitted, even where only mutant virus was detectable in maternal isolates. This is consistent with evidence of loss of transmission with resistance to NNRTI and PI drugs
Time Trends for HIV-1 Antiretroviral Resistance Among Antiretroviral-Experienced and Naive Pregnant Women in New York City During 1991 to Early 2001
Time trends in the prevalence of drug resistance to antiretroviral therapy (ART) in pregnant women have not been studied. Treatment and prophylactic efficacy could be compromised by drug-resistant HIV strains. We conducted a repeated cross-sectional study of antiretroviral resistance mutations to nucleoside reverse transcriptase inhibitors (NRTIs) and nonnucleoside reverse transcriptase inhibitors (NNRTIs) and of major mutations to protease inhibitors (PIs) in virus isolates from 300 HIV-infected pregnant women in New York City from 1991 to early 2001. The overall prevalence of mutations for NRTIs from 1991 to early 2001 was higher for ART-experienced (25.6% [95% confidence interval (CI): 19.1% to 32.1%]) than ART-naive (8.6% [95% CI: 3.7% to 13.4%]) mothers (P \u3c 0.002). For NNRTIs, the overall prevalence of mutations was somewhat higher among ART-experienced (5.8% [95% CI: 2.3% to 9.3%]) versus ART-naive (1.6% [95% CI: 0% to 3.7%]) women (P = 0.06), and increased over time for ART-naive women (0%-7.4%; P = 0.03) and ART-experienced women (0%-19.4%; P = 0.0002). The prevalence of PI-associated mutations was also higher overall among ART-experienced mothers (5.8% [95% CI: 2.3% to 9.3%] vs. 1.6% [95% CI: 0% to 3.7%]; P = 0.06), with increases over time seen for ART-naive women (0%-7.4%; P = 0.03) and ART-experienced women (0%-16.1%; P = 0.0008). The increasing prevalence of drug resistance in pregnant women, including those who are drug-naive, underscores the necessity for resistance testing to guide treatment to achieve suppression of the mother\u27s virus
