Prevalence of Risk Factors for Non-Communicable Diseases for New Patients Reporting to Korle-Bu Teaching Hospital.

BACKGROUND: The risk factors of Noncommunicable diseases (NCDs) are not routinely monitored, especially among populace reporting to hospitals to detect and also advise on preventive measures, a key strategy to reducing the impact of NCDs on the Health Care System and population. METHODS: A cross-sectional survey was carried out between the months of May and June, 2010 among a sample representative of the medical and surgical out-patients population to determine the prevalence of certain risk factors of non-communicable diseases (NCDs). Participants (n = 230) were selected by systematic random sampling. Standardised international protocols were used to measure the prevalence of smoking, alcohol consumption, physical inactivity, obesity, raised blood pressure, raised blood glucose and total cholesterol. RESULTS: The obesity level of the study population was 40.4% with 54% being overweight. Tobacco use among the respondents was 4.8%. Alcohol consumption was 64.8%, with 54.3% of the study population being physically inactive. Almost 48%and 70.9% of the participants consumed fruits and vegetables respectively, at least three days in a week. The prevalence of hypertension was 33.6% for men and 35.2% for women. The prevalence of raised glucose and total blood cholesterol level among the study population was 6.5%. Almost 62% of the participants had a combination of three or more risk factors. CONCLUSION: The prevalence of the significant risk factors in this study were physical inactivity (54.3%), alcohol consumption (64.8%), overweight (54%), obesity (40.4%) and raised blood pressure (34.3%). Hospitals should therefore include NCD risk factor monitoring as part of routine services.

Sexual harassment in public medical schools in Ghana.

OBJECTIVE: This study investigated the prevalence and incidence of Traditional (where a person in a position of power harasses a subordinate) and contra power sexual harassment, (where a subordinate is the harasser of authority figure) in medical schools in Ghana. among. DESIGN: Cross-sectional study. METHOD: Four hundred and nine medical students from four medical schools in Ghana were interviewed. We also considered if academic and financial dependence would predict either traditional or contra power sexual harassment. We further investigated, whether women were more bothered by sexual harassment than men and the correlation between sexual harassment and health. RESULTS: Women were 61% more likely to be sexually harassed than men 39%. Sexual harassment negatively affects the victims' health outcome. We found that the traditional form of sexual harassment was prevalent in medical schools in Ghana and that academic dependence predicted attacks. In the first and second years, women at these institutions are more likely to be sexually harassed than men. CONCLUSION: Sexual harassment policies of medical school need to be widely circulated. The various medical schools should provide reporting procedures and counseling for victims. This paper would inform policy and research.

Hospital all-risk emergency preparedness in Ghana.

OBJECTIVE: This paper assessed the emergency preparedness programs of health facilities for all-risks but focused on Road Traffic Accidents, (RTA) resulting in surge demand. It adopted W. H. O checklist covering hospital preparedness, equipment, manpower and surge capacity planning as best practices for the mitigation of public health emergencies. METHOD: This is a cross-sectional study of purposively selected health facilities. The method used consisted of site visit, questionnaire survey, literature and internet review. The W. H. O. standard for emergency preparedness of health facilities was used to evaluate and assess the nation's hospitals surge capacity programs. The study was conducted between March-June, 2010. A total of 22 district and regional health facilities including teaching hospitals participated in the study. All 10 regions of the country were covered. RESULT: These were: (1) many of the nation's hospitals were not prepared for large RTA's resulting in surge demands, and did not possess general emergency preparedness programs. (2) The hospitals' respective abilities to handle large scale RTA's were compromised by the lack of competent medical and allied health personnel and adequate supplies. DISCUSSION: The inadequacies of the hospital system in responding to emergencies raise serious public health concerns. The biggest challenge facing the hospitals in their emergency intervention is the lack of pre-emergency and emergency preparedness plans as well as the coordination of the hospitals response mechanisms. CONCLUSION: The paper ended with recommendations on how the nation's hospitals and their supervisory agencies could improve emergency preparedness.

Ethics and electronic health information technology: challenges for evidence-based medicine and the physician-patient relationship.

OBJECTIVES: The National Health Insurance Scheme (NHIS), and the National Identification Authority (NIA), pose ethical challenges to the physician-patient relationship due to interoperability. This paper explores (1) the national legislation on Electronic Health Information Technology (EHIT), (2) the ethics of information technology and public health and (3) the effect on the Physician-patient relationship. METHOD: This study consisted of systematic literature and internet review of the legislation, information technology, the national health insurance program, and the physician-patient relationship. RESULT: The result shows that (1) EHIT have eroded a big part of the confidentiality between the physician and patient; (2) The encroachment on privacy is an inevitable outcome of EHIT; (3) Legislation on privacy, the collection, storage and uses of electronic health information is needed and; (4) the nexus between EHIT, NHIS, NHA, Ethics, the physician-patient relationship and privacy. CONCLUSION: The study highlights the lack of protection for physician-patient relationship as medical practice transitions from the conventional to the modern, information technology driven domain.

The medico-legal prerequisite for initiating quarantine and isolation practices in public health emergency management in hospitals in Ghana.

Hospitals and other health facilities in Ghana do not appear to have standardized practices for quarantine and isolation in public health emergency management. This paper reviews the legislative framework governing the medico-legal prerequisites for initiating quarantine and isolation procedures as articulated in the Infectious Disease Act (Cap 78) 1908 amended, 1935, the Quarantine Act (Cap 77) 1915 amended, 1938, the Emergency Powers Act of 1994, (Act 472), and the National Disaster Management Act, 1996, (Act 517) in consonance with the 1992 Constitution of Ghana. The findings provide that (1) The legislative framework outlines systematic standards and protocols to be followed in the committal of person or persons in quarantine and isolation during public health emergencies. (2) These standards and protocols consider as imperative, the creation of standardized national templates for the initiation of quarantine and isolation measures. (3) The non-compliance of the standards and protocols renders vulnerable medical facilities and hospitals with their personnel to the threat of medical malpractice suits and breach of professional ethics. This paper provides suggestions to hospital administrators and medical personnel of how to develop administrative templates in compliance with the law in managing public health emergencies. It also provides examples of such templates for possible adoption by hospitals and other health administrators.

Antimalarial prescribing practices: a challenge to malaria control in Ghana.

OBJECTIVE: The study was conducted to determine antimalarial prescribing practices among prescribers in 2 of the 6 sentinel sites established to document antimalarial drug efficacy in Ghana in order to provide some explanation underlying chloroquine treatment failures in the country. SUBJECTS AND METHODS: The study was descriptive combining both qualitative and quantitative designs. The qualitative design involved in-depth interviews of general prescribers in the Wassa West and Kassena Nankana districts using an interview guide. The quantitative design involved a review of Outpatient Department prescriptions of 100 patients clinically diagnosed as having malaria within the year 2000 in each of the 7 selected health care facilities. RESULTS: The overall number of drugs prescribed per patient encounter was 4.3 in the Wassa West district and 3.0 in the Kassena Nankana district. The number of drugs per patient encounter was 5.4 and 3.7 in private and government health care facilities, respectively. The commonly prescribed antimalarial drug in all the health care facilities visited was chloroquine. However, only 9.8% of prescriptions in private health care facilities contained correct doses of chloroquine compared to 54% in government health care facilities (p = 0.000). Prescriptions containing chloroquine injections were least likely to have correct doses of chloroquine. CONCLUSION: The findings indicate that although chloroquine remained the first-line drug in the treatment of uncomplicated malaria in the two districts, the level of appropriateness of doses prescribed was generally low. Inappropriate doses of chloroquine prescribed were more prevalent in private than government health care facilities, and among prescriptions containing injections.

Mortality in a seven-and-a-half-year follow-up of a trial of insecticide-treated mosquito nets in Ghana.

A 17% efficacy in preventing all-cause mortality in children aged 6-59 months was previously reported from a cluster-randomized controlled trial of insecticide-treated mosquito nets (ITNs) carried out in the Kassena-Nankana District of northern Ghana from July 1993-June 1995. A follow-up until the end of 2000 found no indication in any age group of increased mortality in the ITN group after the end of the randomized intervention. These results should further encourage the use of ITNs as a malaria control tool in areas of high endemicity of Plasmodium falciparum.

Demographic surveillance and health equity in sub-Saharan Africa.

Accurate data are always needed to inform health policy, but are especially critical in tackling health inequities. The growing number of field research stations in sub-Saharan Africa are well-placed to generate relevant data and so support health policy action. Over the past 60 years, demographic surveillance systems have been crucial research tools for the evaluation of health interventions aimed at reducing socioeconomic differentials in mortality and morbidity in sub-Saharan Africa. The bulk of such work has been carried out by field research sites, often operating in remote, resource-constrained settings. The present paper reviews what we have learned since the pioneering work carried out in the field sites of Pholela (South Africa) and Niakhar (Senegal). It then focuses on current efforts to address health equity through INDEPTH, the international network of field sites with continuous demographic evaluation of population and their health in developing countries.

The impact of insecticide-treated bednets on malaria and anaemia in pregnancy in Kassena-Nankana district, Ghana: a randomized controlled trial.

The impact of insecticide-treated bednet use on malaria and anaemia in pregnancy was assessed, as a supplementary study, in a major WHO/TDR-supported bednet trial in northern Ghana between July 1994 and April 1995. The study area was divided into 96 clusters of compounds, with 48 clusters being randomly allocated to intervention. All pregnant women were included in the study but the focus was on primigravidae and secundigravidae. 1961 pregnant women were recruited into the study--1033 (52.7%) in the treated bednet group and 928 (47.3%) in the no net group. 1806 (92.1%) had blood taken for malaria microscopy and haemoglobin determination in the third trimester. Pregnancy outcomes were reported for 847 women. The characteristics of women in intervention and control groups were comparable. The odds ratios, with 95% confidence interval (CI), for different study endpoints were, for Plasmodium falciparum parasitaemia--0.89 (0.73, 1.08), for anaemia--0.88 (0.70, 1.09), for low birthweight (LBW)--0.87 (0.63, 1.19), indicating no benefit for treated bednet use. Effective net use by parity varied from 42% in primigravidae to 63% in multigravidae, in spite of free nets and insecticide impregnation. The main reasons for not using a net were warm weather and perceived absence of mosquito biting. Chloroquine use in pregnancy was low and comparable in both groups. Implications of findings for malaria control in pregnancy and further research are discussed.

Incidence of symptomatic and asymptomatic Plasmodium falciparum infection following curative therapy in adult residents of northern Ghana.

Adult residents of holoendemic malaria regions in Africa have a naturally acquired immunity (NAI) to malaria that renders them more resistant to new infections, limits parasitemia, and reduces the frequency and severity of illness. Given such attributes, it is not clear how one might evaluate drug or vaccine efficacy in adults without serious confounding. To determine symptomatic and asymptomatic malaria attack rates in adults of northern Ghana, 197 men and women underwent curative therapy for any pre-existing malaria infections at the start of the high transmission (wet) season. They were monitored for first parasitemia and first clinical episode of infection by Plasmodium falciparum over a 20-week period (May-October 1996). The cumulative incidence of primary infection by P. falciparum was 0.98 and incidence density of infection was calculated to be 7.0 cases/person-year. Symptoms were reported by 19.5% of the individuals at the time of first recurrent parasitemia. Incidence of infection, parasite density, and the frequency of symptoms were comparable in males and females. The results suggest that NAI did not provide these adults with significant defense against rapid re-infection and suggest that this population-infection design could serve to demonstrate the efficacy of a drug or vaccine in preventing parasitemia.

Rotavirus G and P genotypes in rural Ghana.

An epidemiological study of rotavirus infection was conducted on specimens collected from patients with gastroenteritis and domiciled in the rural Upper Eastern Region of Ghana during 1998. Fifty isolates, randomly selected from 165 human group A rotavirus-positive samples, were G and P characterized by a reverse transcription (RT)-PCR assay using a seminested multiplex method. Rotaviruses of the G3 genotype were found to be the predominant strain (78%), followed by G2 (14%) and G1 (2%). Mixed infections, as shown by combinations of G3 and G2 (4%) and G3 and G1 (2%), were also observed. P typing showed P[4] (72.34%) to be the prevalent strain, followed by P[6] (21.3%), P[8] (2.13%), and a combination of P[4] and P[6] (4.3%).

Severe anemia in young children after high and low malaria transmission seasons in the Kassena-Nankana district of northern Ghana.

Malaria and anemia accounted for 41% and 18% respectively of hospital deaths in the Kassena-Nankana district of northern Ghana during 1996. We measured hemoglobin (Hb), malaria prevalence, and anthropometric indices of 6--24-month-old infants and young children randomly selected from this community at the end of the high (May-October, n = 347) and low (November-April, n = 286) malaria transmission seasons. High transmission season is characterized by rainfall (the equivalent of 800-900 mm/yr.), while the remaining months receive less than 50 mm/yr. Severe anemia, defined as Hb < 6.0 g/dL, was 22.1% at the end of the high transmission season compared to 1.4% at the end of the low transmission season (Odds Ratio [OR] = 20.1; 95% CI: 7.1-55.3). Parasitemia was 71% and 54.3% at these time points (OR = 2.1; 95% CI: 1.5-2.9). Nutritional anemia appeared to have little impact upon this seasonal difference since anthropometric indices were comparable. Although the relative contributions of other causes of severe anemia were not assessed, repeated malaria infections may be a primary determinant of severe anemia among infants and young children during the high transmission season.

Impact of spatial distribution of permethrin-impregnated bed nets on child mortality in rural northern Ghana.

Effects of the distribution in space of permethrin (insecticide)-impregnated bed nets (IIBNS) on child mortality were studied in a randomized controlled trial of IIBNs in a an area highly endemic for Plasmodium falciparum malaria in rural northern Ghana. Eight hundred sixty-two deaths occurred among children 6-59 months of age during 16,841 child-years-at-risk. Mortality increased with the distance from health facilities but not with proximity to identifiable anopheline breeding sites (reservoirs). The efficacy of IIBNs was independent of these distances. Mortality in users of IIBNs was independent of the proximity of nonusers, and mortality rates of nonusers and users living close to each other were similar. Poisson regression estimated a 6.7% increase in mortality among nonusers with each 100-m shift away from the nearest compound with IIBNS, indicating that the insecticide protects nearby nonusers. High coverage of IIBNs achieves maximum impact, but users of IIBNs offer some protection to less fortunate neighbors if coverage is incomplete.

The influence of traditional religion on fertility regulation among the Kassena-Nankana of northern Ghana.

This article presents findings from a study of the influence of traditional religion on reproductive preferences of Kassena-Nankana lineage heads in northern Ghana. Seven reproductive preference questions were administered to nine lineage heads who are primary practitioners of the cult of soothsaying. With the assistance of soothsayers, interviews were repeated in conjunction with the invocation of religious rites in order to determine the views of ancestral spirits on the seven questions. Pairs of lineage head and ancestral interviews are compared to determine the role of traditional religion in shaping male reproductive preferences. Interview pairs reflect a shared preference for sons, large compounds, and a growing lineage. Findings nonetheless show that some ancestral spirits want small families, some even wanting fewer children than corresponding lineage heads. Spiritual consultations are nondogmatic and open to external ideas and influences, suggesting that family planning introduction will not encounter systematic religious opposition among the Kassena-Nankana.

PIP: This study examined fertility preferences among male lineage heads (MLHs) among the Kassena-Nankana of Ghana and the role of traditional religion in determining fertility preferences. Data were obtained via semistructured interviews with MLHs and via contacts with ancestral spirits through soothsayers. MLHs were identified in three micropilot villages with family planning (FP) outreach services in the past year. Three heads were selected at random from the listing of lineages in each village. Interviews were conducted first in the privacy of the home and second in the sacred hut of the soothsayer, who was the medium for the ancestral interviews. Soothsayers advised their clients and participated. Paired responses of MLHs and ancestors showed considerable diversity of opinion and inconsistencies. Questions were asked about the benefits of having many children, the achievement of having the desired number of children, changes of preferences after the fact, male or female preferences, hut size preferences, approval of FP, and the benefits of health and FP service availability. Both MLHs and ancestors shared a strong preference for sons, large compounds, and a growing lineage. However, some ancestors wanted small families. Findings suggest that traditional religious practices were not a singular negative force against FP and were flexible and adaptive to social change. Ancestors acknowledged survival strategies. The methodology suggests the usefulness of communicating with men, soothsayers, and spirits about gender issues, reproductive matters, or other health issues.

Measles incidence, case fatality, and delayed mortality in children with or without vitamin A supplementation in rural Ghana.

Data on measles incidence, acute case fatality, and delayed mortality were collected on 25,443 children aged 0-95 months during the course of a community-based, double-blind, placebo-controlled, randomized trial of vitamin A supplementation in rural, northern Ghana between 1989 and 1991. Measles vaccine coverage in these children was 48%. The overall estimated measles incidence rate was 24.3 per 1,000 child-years, and acute case fatality was 15.7%. There was not significantly increased mortality in survivors of the acute phase of measles compared with controls (rate ratio = 1.22, 95% confidence interval (CI) 0.65-2.30). Reported incidence rates and case fatality were higher in families with low paternal education, in the dry season, and in unvaccinated children, and case fatality was higher in malnourished children. There was no sex difference in incidence, but acute case fatality was somewhat higher in girls than boys (adjusted odds ratio = 1.3, 95% CI 0.9-2.1). Measles incidence was lower in vitamin A-supplemented groups (23.6 per 1,000 child-years) than in placebo groups (28.9 per 1,000 child-years), but this difference was not statistically significant (p = 0.33). Among 946 measles cases in clusters randomized to receive vitamin A or placebo, there was no marked difference in acute measles case fatality between vitamin A-supplemented and placebo groups (15.4% vs. 14.5%, respectively). The biologic effects of vitamin A supplemented on the subsequent clinical manifestations and severity of measles need further elucidation.

PIP: As part of a community-based, placebo-controlled trial of vitamin A supplementation in rural northern Ghana in 1989-91, data were collected on measles incidence and mortality among 25,433 children 0-95 months of age. Measles vaccination coverage was 48%. A total of 961 measles cases were identified, with a median age at onset of 41 months. The overall measles incidence rate was estimated at 24.3/1000 child-years and the acute case fatality rate was 15.7%. Both measles incidence and fatality were higher in families with low paternal education, in the dry season, and in unvaccinated children. Case fatality was also higher in malnourished children. There was a lower, although nonsignificant, measles incidence in vitamin-A supplemented groups (23.6/1000 child-years) than in placebo groups (28.9/1000 child-years). Among 946 measles cases in clusters randomized to receive vitamin A or placebo, there was no marked difference in acute measles case fatality (15.4% and 14.5%, respectively). These findings confirm the importance of sustained measles vaccination in Africa.

The cost-effectiveness of permethrin impregnated bednets in preventing child mortality in Kassena-Nankana district of Northern Ghana.

Permethrin impregnated bednets are now being widely promoted as an effective means of protecting African children against malaria, but there is little evidence of their cost-effectiveness. The impact on child mortality of introducing permethrin impregnated bednets was evaluated in a rural district of northern Ghana in a controlled trial. The cost-effectiveness of the intervention is reported in this paper. The total cost of the intervention over the 2 years of follow-up was US $148,245. Cost per impregnated bednet per year and per person protected per year was US $2.4 and 1.2, respectively. Approximately 16,800 child years were protected and 74 child deaths averted at an estimated cost of US $8.8 per child year protected and US $2003 per death averted. In this rural community, where life expectancy at the mean age of death of trial children was 57.5 years, the estimated cost per discounted healthy life-year gained was US $73.5. Sensitivity analysis suggested that this cost-effectiveness ratio might be reduced substantially by feasible changes in programme implementation. This study supports the argument that the cost-effectiveness of bednet impregnation is sufficiently attractive to make it part of a package of high priority interventions for children. Issues of how to finance the provision of nets and insecticide, and especially the relative contribution of governments, households and donors, need urgently to be addressed.

Acceptability and use of insecticide impregnated bednets in northern Ghana.

A district-wide study was undertaken in a rural population of northern Ghana to identify factors influencing the acceptance and use of insecticide-impregnated bednets (IIBNs). A series of focus group discussions were conducted during 2 years of implementation of IIBNs to gauge community reactions to the introduction of the nets and a structured questionnaire was administered to approximately 2000 randomly selected individuals. Although the IIBNs were accepted and used because they provided protection from mosquito bites, seasonal factors, patterns of use, and questions of cost were key factors likely to influence the dissemination and effectiveness of bednets. Use of the bednets was highly seasonal. Almost all recipients used their IIBNs in the rainy season (99%), corresponding to the period of high mosquito density and 20% used them in the dry seasons, the period of low mosquito density. Mothers with young children were more likely to wash the bednets frequently (because the children soiled the bednets with faeces and urine), resulting in no protection from the insecticide. Provision of wider bednets, or the provision of plastic sheets with the bednets or possible incorporation of the insecticide in washing soaps could improve protection for young children. The success of the promotion of IIBNs in malaria control programmes will depend on the cost of the package and the time of year that it is delivered. Financing mechanisms for individual and village groups are discussed. Social research effectively monitored the intervention in this study, and it should be included as an important component of national malaria control programmes.

Cultural factors constraining the introduction of family planning among the Kassena-Nankana of northern Ghana.

This study presents a focus group investigation of reasons why women in a rural, Sahelian community are reluctant to adopt family planning even when convenient services are made freely available. First, women opting to practice contraception must do so at considerable risk of social ostracism or familial conflict. Implementing individual preference is something that must be done without the support of others. Second, few women view personal decisions about contraceptives as theirs to make. Women and children are the property of the corporate family-kin and community militate against reproductive control. Third, although children are highly valued for a variety of economic, social, and cultural reasons, mortality risks remain extremely high. Low fertility imposes the unacceptable risk that a woman will have no surviving children at the end of her reproductive life. Taken together, these findings attest to the inadequacy of service strategies focused on the contribution of distribution, individual agency, or personal choice. Outreach should also build a sense of community legitimacy for the program, collective health action, and traditional leadership support for family planning behavior.

Drinking water sources, mortality and diarrhoea morbidity among young children in northern Ghana.

In the Upper East Region of Ghana, considerable resources have been invested in the provision of boreholes. As part of the Ghana Vitamin A Supplementation Trials' Survival Study which was carried out in one of the districts of the Upper East Region between January 1989 and December 1991, data were collected over a period of one calendar year on the drinking water sources used by approximately 13,000 mothers/guardians of over 20,000 children and on the morbidity and mortality experiences of these children. These data were used to describe seasonal and geographical variations in drinking water sources; to look for other predictors of water source use; and to establish whether the drinking water source was associated with the risk of child death or the period prevalence of diarrhoea among young children. Boreholes were used as the main source of drinking water by about 60-70% of respondents. They were used slightly more frequently in the dry season. In the rainy season, the use increased of more traditional sources such as rainwater or holes dug in stream beds. The use of boreholes was greatest in the northern zone of the study area and was more common in those who had had some formal education and were of higher socioeconomic status. Some association was found between reported drinking water source and diarrhoeal morbidity, although this association appeared to be seasonal. No significant association was found between drinking water source and child mortality.
