Caring for patients with surgically resectable cancers: experience from a specialised centre in rural Rwanda

SETTING

Butaro Cancer Centre of Excellence (BCCOE), Burera District, Rwanda.

OBJECTIVES

To describe characteristics, management and 6-month outcome of adult patients presenting with potentially surgically resectable cancers.

DESIGN

Retrospective cohort study of patients presenting between 1 July and 31 December 2012.

RESULTS

Of 278 patients, 76.6% were female, 51.4% were aged 50-74 years and 75% were referred from other district or tertiary hospitals in Rwanda. For the 250 patients with treatment details, 115 (46%) underwent surgery, with or without chemotherapy/radiotherapy. Median time from admission to surgery was 21 days (IQR 2-91). Breast cancer was the most common type of cancer treated at BCCOE, while other forms of cancer (cervical, colorectal and head and neck) were mainly operated on in tertiary facilities. Ninety-nine patients had no treatment; 52% of these were referred out within 6 months, primarily for palliative care. At 6 months, 6.8% had died or were lost to follow-up.

CONCLUSION

Surgical care was provided for many cancer patients referred to BCCOE. However, challenges such as inadequate surgical infrastructure and skills, and patients presenting late with advanced and unresectable disease can limit the ability to manage all cases. This study highlights opportunities and challenges in cancer care relevant to other hospitals in rural settings.

Xpert(®) MTB/RIF under routine conditions in diagnosing pulmonary tuberculosis: a study in two hospitals in Pakistan

Xpert(®) MTB/RIF testing was offered to consecutive patients with presumptive tuberculosis (TB) attending two hospitals in Pakistan during April-May 2012, in addition to routine diagnostic protocol (smear microscopy, chest radiography and clinical judgement). We assessed the relative contribution of each tool in detecting pulmonary TB under routine conditions. Of 606 participants, 121 (20%) were detected as pulmonary TB: 46 (38%) by microscopy, 38 (31%) by Xpert alone and 37 (31%) on clinical and radiological grounds; 41 (65%) were detected by both Xpert and microscopy. One patient had rifampicin resistance. Although Xpert detected approximately twice as many TB cases as microscopy (n = 79, 65%), clinical judgement remained favoured by clinicians even when smear and Xpert were negative.

Tuberculosis treatment outcomes among hospital workers at a public teaching and national referral hospital in Kenya

SETTING

Kenyatta National Hospital (KNH), Nairobi, Ken-ya, a large referral and teaching hospital.

OBJECTIVE

1) To document tuberculosis (TB) case notification rates and trends; 2) to describe demographic, clinical and workplace characteristics and treatment outcomes; and 3) to examine associations between demographic and clinical characteristics, HIV/AIDS (human immunodeficiency virus/acquired immune-deficiency syndrome) treatment and anti-tuberculosis treatment outcomes among hospital workers with TB at KNH during the period 2006-2011.

DESIGN

A retrospective cohort study involving a review of medical records.

RESULTS

The TB case notification rate among hospital staff ranged between 413 and 901 per 100 000 staff members per year; 51% of all cases were extra-pulmonary TB; 74% of all cases were among medical, paramedical and support staff. The TB-HIV coinfection rate was 60%. Only 75% had a successful treatment outcome. Patients in the retreatment category, those with unknown HIV status and those who were support staff had a higher risk of poor treatment outcomes.

CONCLUSION

The TB case rate among hospital workers was unacceptably high compared to that of the general population, and treatment outcomes were poor. Infection control in the hospital and management of staff with TB requires urgent attention.

Diagnostic management and outcomes of pulmonary tuberculosis suspects admitted to a central hospital in Malawi

SETTING

Zomba Central Hospital, Malawi.

OBJECTIVE

To determine diagnostic management and outcomes of pulmonary tuberculosis (PTB) suspects admitted to adult wards.

DESIGN

A retrospective, cross-sectional review of medical records of patients admitted to hospital between July and September 2010.

RESULTS

There were 141 PTB suspects. Sputum examination was requested and performed in 67 (48%) suspects, but none were smear-positive. Chest X-ray (CXR) was requested and performed in 26 (39%) suspects whose sputum smears were negative. Eleven suspects had a CXR suggestive of PTB: two were started on TB treatment and eight died before treatment started. Human immunodeficiency virus (HIV) status was known for 50 patients (35% of all suspects) on admission, all of whom were HIV-positive. HIV testing was requested for 37 patients, but was only performed in 12, five of whom were HIV-positive. Only one patient was referred for antiretroviral treatment. There were 41 (29%) deaths, eight of whom had probable TB and were not treated. In the remaining 33 patients who died, only nine (27%) had sputum smears examined and four (12%) had a CXR.

CONCLUSION

The study shows inadequacies in the diagnostic management of PTB suspects in the Zomba Central Hospital, but suggests opportunities for improvement.

Tuberculosis treatment outcomes among retreatment patients registered by private practitioners in Myanmar

The objectives of this retrospective cohort study were to report treatment outcomes and identify factors associated with treatment failure among all retreatment tuberculosis (TB) patients registered in the public-private mix DOTS programme of Populations Services International-Myanmar over 6 years. Among 3643 retreatment patients, 2657 (73%) were successfully treated and 309 (8.5%) failed. This study shows that retreatment patients who have failed treatment for their first TB episode are almost twice as likely to fail a second time (13.5%). We have identified some key programmatic challenges associated with retreatment TB in the private sector, and steps are being taken to address this issue.

Attitudes towards involuntary incarceration for tuberculosis: a survey of Union members

BACKGROUND

Policies involving the use of involuntary incarceration for tuberculosis (TB) are highly ethically controversial. To encourage ethical reflection within the International Union Against Tuberculosis and Lung Disease (The Union), the Ethics Advisory Group (EAG) surveyed members regarding their attitudes and values relating to involuntary incarceration for TB.

METHODS

Members of the Union TB section were invited to respond to an anonymous web-based survey. The survey included both multiple choice questions describing a range of scenarios regarding involuntary incarceration, and free-text fields inviting respondents to provide general comments on ethical issues.

RESULTS

The survey was completed by 194 participants, 33 (17%) of whom were opposed to involuntary incarceration on principle. The age and sex of the respondents was not associated with likelihood of principled opposition; respondents from North America were least likely to be opposed to involuntary incarceration (P = 0.02). Respondents were most likely to consider involuntary incarceration for persons with known multidrug-resistant TB or a history of previous treatment default, and least likely where people lived alone, were university-educated or the main income provider for their families.

CONCLUSION

This survey found a wide range of viewpoints regarding involuntary incarceration, and highlights a number of key elements in ethical engagement with the tensions surrounding involuntary incarceration. We provide commentary on approaches to ethical policy making in the light of these findings.

Childhood immunisation in Bungoma County, Kenya, from 2008 to 2011: need for improved uptake

Uptake of immunisations in children aged 1-2 years in Bungoma County, Kenya, was determined as part of the 6-monthly Health and Demographic Surveillance System surveys. A total of 2699 children were assessed between 2008 and 2011. During this time period, full immunisation declined significantly from 84% to 58%, and measles vaccine declined uptake from 89% to 60% (P < 0.001). Each year there was a significant fall-off for the third doses of the oral polio and pentavalent vaccines (P < 0.001). These findings are of concern, as low immunisation coverage may lead to vaccine-preventable disease outbreaks. Further investigations into the reasons for declining immunisation trends are required.

Research ethics in The Union: an 8-year review of the Ethics Advisory Group

SETTING

The Ethics Advisory Group (EAG) of the International Union Against Tuberculosis and Lung Disease (The Union) was established in 2004 to provide ethical guidance and promote ethical standards within The Union, including reviews of proposed research projects associated with The Union.

OBJECTIVES

To describe research proposal reviews conducted by the EAG in the period 2005-2012 in terms of 1) annual numbers, 2) the Union departments in which the proposals originated, 3) study designs, 4) regions and countries where studies were to be conducted, 5) study topics, 6) problems encountered by the EAG, and 7) review outcomes.

DESIGN

Descriptive study of application records of the EAG.

RESULTS

A total of 292 applications were reviewed; 79% were proposals for operational research; 85% were from Africa and Asia, with 64% from India, South Africa, Malawi, Kenya and Zimbabwe. Tuberculosis was the topic in 68%; only three studies in the 8 years were on other lung diseases. Several problems encountered are highlighted. All applications were approved except six, either immediately or after modification.

CONCLUSION

The proposal review process of the EAG serves to maintain ethical standards of research within The Union. Ideas for expanding the scope of the EAG are discussed.

Oops, what about ethics?

Ethics approval of research studies is essential for the protection and rights of study subjects, whether this is for prospective research or record reviews. This article shares a painful lesson learned from a field experience where the appropriate steps for obtaining ethics approval were not followed by a young researcher. This researcher had embarked on an operational research project, but had omitted to seek ethics approval from a local ethics committee. Young researchers, particularly from low- and middle-income countries, need to learn about the importance and value of ethics.

Language in tuberculosis services: can we change to patient-centred terminology and stop the paradigm of blaming the patients?

The words 'defaulter', 'suspect' and 'control' have been part of the language of tuberculosis (TB) services for many decades, and they continue to be used in international guidelines and in published literature. From a patient perspective, it is our opinion that these terms are at best inappropriate, coercive and disempowering, and at worst they could be perceived as judgmental and criminalising, tending to place the blame of the disease or responsibility for adverse treatment outcomes on one side-that of the patients. In this article, which brings together a wide range of authors and institutions from Africa, Asia, Latin America, Europe and the Pacific, we discuss the use of the words 'defaulter', 'suspect' and 'control' and argue why it is detrimental to continue using them in the context of TB. We propose that 'defaulter' be replaced with 'person lost to follow-up'; that 'TB suspect' be replaced by 'person with presumptive TB' or 'person to be evaluated for TB'; and that the term 'control' be replaced with 'prevention and care' or simply deleted. These terms are non-judgmental and patient-centred. We appeal to the global Stop TB Partnership to lead discussions on this issue and to make concrete steps towards changing the current paradigm.

Symptom screen: diagnostic usefulness in detecting pulmonary tuberculosis in HIV-infected pregnant women in Kenya

OBJECTIVE

To determine the diagnostic usefulness of tuberculosis (TB) symptom screening to detect active pulmonary TB among human immunodeficiency virus (HIV) infected pregnant women in two PMTCT (prevention of mother-to-child transmission) clinics in western Kenya that are supported by the United States Agency for International Development-Academic Model Providing Access to Healthcare partnership.

DESIGN

Cross-sectional study. Participants were interviewed for TB symptoms with a standardized questionnaire (cough >2 weeks, fever, night sweats, weight loss or failure to gain weight). Those with cough submitted sputum specimens for smear microscopy for acid-fast bacilli and mycobacterial culture. Women at >14 weeks gestation underwent shielded chest radiography (CXR).

RESULTS

Of 187 HIV-infected women, 38 (20%) were symptom screen-positive. Of these, 21 had a cough for >2 weeks, but all had negative sputum smears and mycobacterial cultures. CXRs were performed in 26 symptomatic women: three were suggestive of TB (1 miliary, 1 infiltrates and 1 cavitary). Of 149 women with a negative symptom screen, 100 had a CXR and seven had a CXR suggestive of TB (1 cavitary, 2 miliary and 4 infiltrates).

CONCLUSION

This study did not support the utility of isolated symptom screening in identification of TB disease in our PMTCT setting. CXR was useful in identification of TB suspects in both symptomatic and asymptomatic women.

Surveillance for MDR-TB: is there an obligation to ensure treatment for individuals identified with MDR-TB?

This article raises ethical issues that result if individuals, during the course of research to measure the prevalence of drug-resistant tuberculosis, are identified with the disease but are not provided with or referred for appropriate treatment. It draws attention to and applauds recently published World Health Organization guidelines on the subject. Questions posed are: 1) Should treatment be provided for individuals identified through surveillance projects for MDR-TB, whatever their purpose (specific research or 'routine' national prevalence studies)? 2) If treatment availability is a problem, who is responsible for assuring this?

Tuberculosis culture testing at a tertiary care hospital: options for improved management and use for treatment decisions

SETTING

Chris Hani Baragwanath Hospital, a tertiary care hospital in Johannesburg, South Africa.

OBJECTIVES

To determine the proportion of patients with positive Mycobacterium tuberculosis cultures and whether those who were positive were on treatment.

DESIGN

Tuberculosis (TB) culture results were obtained from the laboratory for a 3-month period. Positive results were checked against registrations at the hospital TB Care Centre (TBCC). The treatment status of non-registered patients was obtained from various records at the hospital, district clinics and from home visits.

RESULTS

Overall, 3909 patients had 5404 samples sent for culture. Of these, 708 patients (18%) had at least one positive culture. The positive yield from 2749 adult sputum samples was 33% and ranged from 6% to 40% for different extra-pulmonary specimens. Among 1160 children, the yield varied from 0% to 12%, with 12% in sputum and gastric washing specimens. Of the 708 culture-positive patients, 429 (61%) patients were registered at the TBCC and were known to have started TB treatment. Of the 279 subjects not registered (39% overall), 100 (36%) died. Only 67 of the 179 survivors were confirmed on treatment, 40 were not on treatment and 72 could not be traced.

CONCLUSIONS

Large numbers of TB culture tests were performed, some inappropriately. Study findings highlight inadequacies in the management of culture-confirmed TB at this hospital.

Tuberculosis at Chris Hani Baragwanath Hospital: an intervention to improve patient referrals to district clinics

SETTING

A study in 2001 described the process of managing tuberculosis (TB) at Chris Hani Baragwanath hospital, the numbers of patients diagnosed and poor outcomes of referring patients to clinics in the adjacent sub-districts. The present study describes and evaluates an intervention to address the problems.

OBJECTIVES

To describe the intervention process (education and referral of TB patients) and the subsequent results over a 2-year period from 2003 to 2005.

METHODS

The process of establishing the system and how it was evaluated at district clinics in Johannesburg are described.

RESULTS

In the first 2 years of operation, August 2003 to July 2005, 13,138 patients were registered. Extra-pulmonary tuberculosis (EPTB) was diagnosed in 34%. Of the 46% tested for human immunodeficiency virus (HIV), 93% were positive. Successful referral to clinics was achieved for 94% of patients.

CONCLUSIONS

Very large numbers of patients are diagnosed with TB at Chris Hani Baragwanath Hospital. A TB care centre has successfully addressed important referral, education and registration requirements for the comprehensive management of TB with links to clinics. It is suggested that this model be applied at other hospitals.

Tuberculosis at Chris Hani Baragwanath Hospital: numbers of patients diagnosed and outcomes of referrals to district clinics

SETTING

Chris Hani Baragwanath Hospital, in Johannesburg. South Africa is experiencing a serious epidemic of tuberculosis (TB), with a measured rate of 500 cases per 100,000 population. Patients in public hospitals are referred for treatment to district clinics or to specific TB hospitals.

OBJECTIVES

To measure numbers of patients diagnosed with TB, and to describe the type of disease and referral outcomes.

METHODS

A descriptive study of patients diagnosed with TB in a tertiary hospital. Data in patient files were collected for medical and paediatric patients, and patients were interviewed by researchers who visited clinics to check if referred patients had attended.

RESULTS

In the 8-week study period, 1291 patients were diagnosed with TB: 74% had pulmonary disease and 80% of those tested for HIV were positive; 19% died in hospital, and 21% required transfer to a TB hospital. Only half of the patients referred to clinics attended within 2 weeks.

CONCLUSIONS

Patients with advanced TB are commonly seen at this hospital. Notifications were an inadequate record and an unacceptable proportion of patients were lost between hospital and clinics. This study has recommended that opportunities for education and discussion must be provided if patients are to reach clinics successfully.

Patients' beliefs: do they affect tuberculosis control? A study in a rural district of South Africa

SETTING

A rural district of South Africa.

OBJECTIVES

To describe the beliefs and experiences about tuberculosis of patients and community members and to suggest how these affect presentation to health services and treatment adherence.

DESIGN

A descriptive study using structured interviews with individual patients, and focus group interviews with patients and community groups.

RESULTS

There is a strong belief in this community that tuberculosis is the result of breaking cultural rules that demand abstinence from sex after the death of a family member and after a woman has a spontaneous abortion. People believe that the resulting disease can only be treated by traditional healers. This delays presentation to hospitals or clinics. There is also a belief in a 'western' type TB that can spread from sufferers or is due to environmental pollution or to smoking or alcohol excesses. A number of factors were cited that influenced adherence to treatment. These included the stigma of TB, the belief that there should be abstinence from sex while on treatment, difficulties accessing health services, long waits and unacceptable health worker attitudes.

CONCLUSIONS

With the increasing rates of tuberculosis in South Africa, strenuous measures are needed to implement a good control programme that will increase the cure rate of tuberculosis patients. The results of this study suggest the need for health workers to learn about local beliefs that may influence presentation and adherence, and for traditional and western health workers to collaborate.

Cause of death of patients on treatment for tuberculosis: a study in a rural South African hospital

SETTING

Tintswalo Hospital, a rural district hospital in South Africa.

OBJECTIVES

To assess the quality of data relating to deaths from tuberculosis; to determine the actual cause of death of patients who die whilst on tuberculosis treatment.

DESIGN

A descriptive study of all patients who were treated for tuberculosis between January 1992 and June 1996, and who died during their course of treatment. A review of records, X-rays and death certificates of patients whose cause of death was recorded as tuberculosis. Verbal autopsies were done for patients who died at home. Deaths were classified into one of five categories: definitely, likely or possibly due to tuberculosis, unlikely or not due to tuberculosis, based on criteria such as bacteriological confirmation of tuberculosis and the presence of other illnesses.

RESULTS

There were 927 cases of tuberculosis and 80 deaths recorded as due to tuberculosis. Valid criteria or detailed information were available for only 68 patients. Only 56% of deaths were confirmed or likely to be due to tuberculosis, and 12% of patients probably did not have tuberculosis at all. The remaining 32% had tuberculosis but died of other illnesses.

CONCLUSIONS

The recorded tuberculosis mortality data were clearly inaccurate. There is a need to improve tuberculosis diagnosis, documentation on death certificates, and tracing of treatment interrupters in order to determine whether or not they have died.

Tuberculosis patient care decentralised to district clinics with community-based directly observed treatment in a rural district of South Africa

SETTING

A rural district of the Northern Province, South Africa.

OBJECTIVES

To measure the effect of decentralisation of a tuberculosis service in a rural area on treatment outcomes.

DESIGN

An intervention study that measured treatment outcomes of patients attending district clinics for tuberculosis treatment and compared these with outcomes of patients attending the district hospital.

RESULTS

Over the 4-year period 1992-1995, 928 patients were admitted to the tuberculosis unit of the district hospital. In the initial pre-intervention phase, the best estimate of completed treatment for all 503 cases was 61%, and for 206 new smear-positive patients it was 67%. The intervention process established a tuberculosis control programme with directly observed treatment for all patients, and training and supervision of clinic staff. Ninety per cent of all patients had community-based supporters. For most patients, cure was not proven, but assuming success from completion of and proven adherence to treatment, successful outcomes for new smear-positive cases rose to 82% for decentralised (clinic) treatment, and 88% for those patients who lived in the district but attended the hospital for treatment.

CONCLUSIONS

These findings suggest that district clinics can achieve the same good results as the hospital. It is recommended that tuberculosis control needs a dedicated co-ordinator at district level to manage the necessary infrastructural and staff resources.

An outbreak of meningococcal meningitis in Gauteng, Spring 1996

OBJECTIVE

To describe a Neisseria meningitidis outbreak in Gauteng during the period 1 July to 31 December 1996.

DESIGN

A descriptive study.

SETTING

Patients with meningococcal meningitis in Gauteng who had been diagnosed by laboratory means, or notified during the period 1 July to 31 December 1996.

MAIN OUTCOME MEASURES

Data including age, sex, date of admission to hospital, N. meningitidis serogroup and outcome were collected from Gauteng notification lists, South African Institute of Medical Research (SAIMR) records, a linelist compiled by the Gauteng Health Department, and hospital records.

RESULTS

A total of 201 patients was studied; of this number 87 (43%) had been notified. Seventy per cent of cases were below 30 years of age and 78% were male. More than half (54%) of the cases were from the West Rand. The case fatality rate for 70 cases of known outcome was 14%. Serotyping of 85 isolates showed that a majority (76%) were serogroup A, with 57% being serogroup A clone I-1. Serogroup A clone III-1 accounted for 14% of the typed isolates. All isolates were sensitive to penicillin with minimum inhibitory concentrations of < 0.05 microgram/ml.

CONCLUSION

In 1996 Gauteng experienced an epidemic of serogroup A meningococcal meningitis. The serotype that caused the majority of cases had been recorded in South Africa before, but serogroup A clone III-1, responsible for epidemics spreading across two continents, was recorded in South Africa for the first time. Notification of cases by health workers was inadequate in this epidemic.

Child health in farm workers' communities

Black women who had borne one or more children in the 5 years preceding the study and who were resident on white-owned farms were sampled in a multistage cluster procedure from the population of two magisterial districts of the southern Transvaal, Ventersdorp and Balfour. The purpose of this study was to determine mothers' knowledge and behaviour regarding the health of their children, to correlate this with personal and social characteristics of the mothers, and to document aspects of their physical environment. Only 50% of mothers had completed 4 or more years of formal education. One in three had experienced the death of at least 1 of her children. Water and sanitation facilities were inadequate for most. Little was known about oral rehydration solution preparation or about growth monitoring. Most children were breast-fed. Between 50% and 63% of the children had vaccinations appropriate for their ages, depending on whether evidence from clinic cards or from mothers' memories was taken as valid. The single most important determinant of the appropriate knowledge and behaviour of mothers was education. Basic living and social conditions of farm workers require improvement and the health services must be re-orientated to deliver comprehensive primary care.

Doctors in rural hospitals in KwaZulu and Natal

Maintaining adequate medical staffing in rural hospitals remains a serious problem. A study was undertaken to discover why doctors came to work in rural hospitals, why they stay, and why they leave. Doctors in rural hospitals in KwaZulu and Natal were surveyed using a postal questionnaire. A total response rate of 74% was obtained. Based on the results, specific recommendations are made for improving working conditions and training and the support needs of doctors in rural hospitals.

Oral rehydration solutions in 'section 30' areas. A study in two farming districts in the southern Transvaal

Six hundred and twenty-three black mothers of young children were interviewed on the white-owned farms on which they lived and/or worked in two magisterial districts of the southern Transvaal. Only 8% described an acceptable method of preparing oral rehydration solution (ORS). Of those mothers whose children had recently had diarrhoea, 5% had given ORS. Thirty-one per cent of mothers had litre containers, sugar and salt in their homes, while 84% had cups, sugar and salt. Recommendations are made about health education appropriate to the needs and the resources of black women living on farms.

Vaccine cold-chain status in the Elim health ward of Gazankulu

The vaccine cold-chain is a fundamental component of any immunisation programme. This study used chemical-based temperature indicators to monitor the cold-chain constantly in the Elim Hospital health ward of Gazankulu. It was found that the cold-chain was adequately maintained at the hospital, but that as vaccine travelled towards the periphery severe breaks in the cold-chain occurred. Eighteen per cent of vaccines at the Elim Hospital store and up to 90% at the periphery were potentially exposed to temperatures high enough and for a sufficient length of time to have affected their potency. More emphasis needs to be placed on maintaining the cold-chain if we are to reach to EPI's goal of immunisation for all children by the year 1990.
