Human resources for control of tuberculosis and HIV-associated tuberculosis.

The global targets for tuberculosis (TB) control were postponed from 2000 to 2005, but on current evidence a further postponement may be necessary. Of the constraints preventing these targets being met, the primary one appears to be the lack of adequately trained and qualified staff. This paper outlines: 1) the human resources and skills for global TB and human immunodeficiency virus (HIV) TB control, including the human resources for implementing the DOTS strategy, the additional human resources for implementing joint HIV-TB control strategies and what is known about human resource gaps at global level; 2) the attempts to quantify human resource gaps by focusing on a small country in sub-Saharan Africa, Malawi; and 3) the main constraints to human resources and their possible solutions, under six main headings: human resource planning; production of human resources; distribution of the work-force; motivation and staff retention; quality of existing staff; and the effect of HIV/AIDS. We recommend an urgent shift in thinking about the human resource paradigm, and exhort international policy makers and the donor community to make a concerted effort to bridge the current gaps by investing for real change.

Performance-related allowances within the Malawi National Tuberculosis Control Programme.

SETTING: National Tuberculosis (TB) Control Programme (NTP), Malawi. OBJECTIVES: To determine the feasibility and effectiveness of performance-related allowances for NTP personnel working at central and regional levels in Malawi. In particular, to determine 1) whether programme staff can complete 6-monthly self-assessment forms related to the tasks they are expected to perform during that period, and 2) whether the NTP can achieve four key programme targets related to case finding, treatment outcome and the sending of sputum specimens for drug resistance monitoring. DESIGN: A descriptive study. RESULTS: For January to June 2003, 25 personnel completed self-assessment forms, and in all cases individual performance was judged satisfactory. For July to December 2003, 21 personnel completed self-assessment forms, and in 20 cases individual performance was judged satisfactory. In the first quarter of 2003, only one target was achieved for the country, and NTP personnel were awarded one quarter of the performance payment. In the third quarter, two targets were achieved and NTP personnel were awarded one half of the performance payment. CONCLUSION: It is feasible to implement performance-related payments for NTP personnel. Ways to routinely introduce such a system for NTP and other staff in the health sector urgently need to be explored.

Scaling up HIV/AIDS and joint HIV-TB services in Malawi.

Two country-wide surveys were undertaken to assess progress in scaling up human immunodeficiency virus/ acquired immune-deficiency syndrome (HIV/AIDS) and HIV-tuberculosis (TB) services in the public health sector in Malawi between 2002 and 2003. In 2003, 118 sites were performing counselling and HIV testing compared with 70 in 2002. There were 215 269 HIV tests carried out in 2003 compared with 149 540 in 2002, the largest increases being in pregnant women (from 5059 to 26791), patients with TB (from 2130 to 3983) and patients/clients attending health facilities (from 35 407 to 79 584). In 2003, 3703 patients with AIDS were started on antiretroviral therapy compared with 1220 patients in 2002.

Scaling up antiretroviral therapy in Africa: learning from tuberculosis control programmes--the case of Malawi.

The rapid and massive scale-up of antiretroviral drug therapy (ART) so needed in sub-Saharan Africa will not be possible using a 'medicalised' model. A more simple approach is required. DOTS has been used now for many years to provide successful anti-tuberculosis treatment to millions of patients in poor countries of the world, and many of the established concepts can be used for the delivery of ART. Malawi, a small and impoverished country in sub-Saharan Africa, is embarking on a national scale-up of ART. In this review we describe how we have adopted several of the principles of DOTS for delivering ART in Malawi: case finding and registration, treatment, monitoring, drug procurement, staffing and the issue of free drugs. We also discuss ART for HIV-infected TB patients. We hope that by using the DOTS approach we will be able to deliver ART to large numbers of HIV-infected patients under controlled conditions, and minimise the risk of developing drug resistance.

Voluntary counselling, HIV testing and adjunctive cotrimoxazole are associated with improved TB treatment outcomes under routine conditions in Thyolo District, Malawi.

SETTING: Two rural districts in Malawi: Thyolo, where voluntary counselling and human immunodeficiency virus (HIV) testing (VCT) is offered to all tuberculosis (TB) patients and adjunctive cotrimoxazole to HIV positives, and Mulanje, where no such interventions are offered. OBJECTIVES: For all TB patients registered in 2001: 1) to determine the uptake of VCT and cotrimoxazole in Thyolo, and 2) to compare treatment outcomes between Thyolo and Mulanje. DESIGN: A cohort study using routinely collected programme data. RESULTS: There were 1239 TB patients in Mulanje and 1103 in Thyolo. In Thylo, 1064 (97%) patients consented to VCT, 1006 were HIV tested (91%) and 761 (69%) were started on cotrimoxazole a median of 4 days from registration; 77% of patients tested in Thyolo were HIV-positive. For all TB patients, in Thyolo and Mulanje, treatment success was respectively 75% and 61% (P < 0.001); death was 21% and 25% (P = 0.026); and other outcomes were 4% and 14% (P < 0.001). The adjusted relative risks of treatment success (1.23), death (0.84) and other outcomes (0.26) in Thyolo were significantly different from those in Mulanje (P < 0.001). CONCLUSION: VCT and adjunctive cotrimoxazole is well accepted by TB patients in Thyolo and, with other HIV care and support services, is associated with good treatment outcome indicators for the National Tuberculosis Programme. This intervention is being expanded to other districts in Malawi, and other African countries should consider a similar approach to the dual HIV-TB epidemic.

Tuberculosis control in Malawian prisons: from research to policy and practice.

Following an operational research study in Zomba Central Prison, Malawi, in 1996, the National Tuberculosis Control Programme (NTP) and the Prison Medical Services worked together to improve the diagnosis and treatment of tuberculosis (TB) in prisoners. Prisoners are screened for TB on admission and during their prison sentences. A system was established of treating patients, according to NTP guidelines, while in prison and on discharge from prison. Monitoring and evaluation is undertaken using TB officers at district and regional level, and 6-monthly meetings are held with all stakeholders and the central unit to collate data and review prison TB control activities.

Use of a multiple choice questionnaire to stimulate TB officers to read the TB manual in Malawi.

Forty-four tuberculosis (TB) officers who attended the National TB Seminar were given a multiple choice questionnaire (MCQ), based on information in the TB manual. They were asked to complete the MCQ in their hospitals, using the manual, and return it within 6 weeks to the Central Unit. Thirty-one (70%) officers returned completed MCQs. There was negative marking for incorrect answers. The mean mark was 69%. Twelve (39%) officers scored 80% or higher and four (13%) scored below 50%. MCQ assessments may be a useful way of stimulating TB officers to read TB manuals and other guidelines.

Using a bus service for transporting sputum specimens to the Central Reference Laboratory: effect on the routine TB culture service in Malawi.

SETTING: All non-private hospitals in Malawi that registered TB cases in 2001, during which there was a bus service for transporting sputum specimens to the Central Reference Laboratory (CRL) for mycobacterial culture and drug sensitivity testing (CDST). OBJECTIVES: To determine the performance of the system of collecting and processing sputum specimens from patients with recurrent smear-positive pulmonary TB through to CDST. DESIGN: Structured interviews with TB Officers, and retrospective data collection using TB and laboratory registers. RESULTS: There were 964 patients with recurrent smear-positive PTB. TB Officers took responsibility for collecting and transporting sputum to the CRL, and 73% reported using the bus service. Sputum specimens from 384 (40%) patients arrived at the CRL. Of these, 40% were found to have negative concentrated smears at the CRL, and 36% of specimen sets arriving at CRL were successfully cultured for DST. Most specimens had been collected after the start of anti-tuberculosis treatment. Although delays in collection adversely affected culture, only 43% of specimen sets collected on or before the first day of treatment yielded Mycobacterium tuberculosis. CONCLUSION: Problems were identified at all stages of the system and strategies to remedy these are being put in place.

Characteristics and outcome of tuberculosis patients whose sputum smears are positive at or after 5 months of treatment.

A country-wide survey was carried out to assess the management of new smear-positive pulmonary TB (PTB) patients whose sputum smears were recorded as positive 5 months or later during treatment. During 2000 and 2001, there were 250 patients, of whom 161 (64%) had positive smears at 5 months and 89 at 7 months. Several inconsistencies and inadequacies in management were identified which need to be remedied: 7% of patients were assessed on one sputum specimen instead of two, and 17% on the basis of one positive smear result; 47% of patients with 5-month positive smears and 52% with 7-month positive smears had sputum smears examined too early or too late; 14% of patients with 5-month positive smears continued treatment, and over 60% of these were recorded as 'cured'.

When are follow-up sputum smears actually examined in patients treated for new smear-positive pulmonary tuberculosis?

SETTING: All 44 non-private hospitals (four central, 22 district and 18 mission) in Malawi that registered and treated tuberculosis (TB) cases, October-December 2001. OBJECTIVES: To determine, in new smear-positive pulmonary tuberculosis (PTB) patients, for the 2-, 5- and 7-month smear examinations, 1) the proportion with smears examined and 2) the actual timing of smear examination. STUDY DESIGN: Retrospective data collection using TB registers, TB treatment cards and laboratory sputum registers. Timing of smear examinations was judged acceptable if 2-month smears were examined at 2 or 3 months, 5-month smears at 4, 5 or 6 months and 7-month smears at 6, 7, 8 or 9 months. RESULTS: Of 1994 patients, for those alive and on treatment, 78% had smears definitely examined at 2 months, 75% at 5 months and 74% at 7 months. Of these, 82% had smears examined at an acceptable time for the 2-month smear, 71% for the 5-month smear and 78% for the 7-month smear. Smears were examined after the 8-month treatment regimen for the 2- and 5-month smear in respectively 2% and 9% of patients. Smears were done more frequently in female than male patients, and in district/mission hospitals than central hospitals. Smears were done at acceptable times more frequently in younger than older patients and in mission/central hospitals than district hospitals. CONCLUSION: During supervision, the actual time of follow-up sputum smear examinations needs to be monitored more closely.

Prescriptions and dosages of anti-tuberculosis drugs in the National Tuberculosis Control Programme of Malawi.

SETTING: All 44 non-private hospitals in Malawi treating pulmonary tuberculosis (PTB) patients with an oral regimen (0.5RHZE/1.5R3H3Z3E3/6HE). OBJECTIVES: In new smear-positive PTB patients, to determine whether: 1) numbers of tablets were correctly prescribed according to pre-treatment weights, and 2) medication dosages were adequate, too low or too high. DESIGN: Retrospective review of TB registers and TB treatment cards for patients registered with new smear-positive PTB between 1 October and 31 December 2001. RESULTS: Of 1970 patients aged > or = 15 years, 1211 (62%) had treatment cards and pre-treatment weights. Incorrect prescriptions were given to 88 (7%), and many of these received dosages of anti-tuberculosis drugs that were too high or too low. For those receiving correct prescriptions, daily treatment in the initial and continuation phases was generally associated with adequate dosages of drugs. However, in the initial intermittent phase, between 3% and 40% of patients received anti-tuberculosis drug dosages that were too low. CONCLUSION: A small percentage of patients receive incorrect prescriptions, which can be resolved by training and supervision. In those receiving correct prescriptions, intermittent treatment provides dosages that are sometimes too low. Weight bands for intermittent treatment should be re-examined.

Counselling, HIV testing and adjunctive cotrimoxazole for TB patients in Malawi: from research to routine implementation.

SETTING: Fifteen hospitals in Malawi that offer voluntary counselling and testing (VCT) for the human immunodeficiency virus (HIV) for tuberculosis (TB) patients and cotrimoxazole (CTX) for patients found to be HIV-positive. OBJECTIVES: 1) To describe the process of developing a national TB-HIV plan, conducting a country-wide situational assessment, and producing national guidelines on VCT and CTX for TB patients, and 2) to assess the implementation of VCT and CTX for TB patients registered between July and September 2003. DESIGN: A descriptive study. RESULTS: The 3-year HIV-TB plan was finalised in 2002. Between January and March 2003, an assessment was carried out of HIV/AIDS and joint HIV-TB services in Malawi and a decision made to support 15 hospitals in implementing VCT and CTX for TB patients. Between April and June 2003, national guidelines on VCT and CTX were developed through a consultative process, and treatment units were prepared for implementation. Between July and September 2003, 2397 TB patients were registered, and 1404 (59%) accepted VCT; 956 (68%) were HIV-positive, of whom 927 (97%) started CTX. Deficiencies in the registration process and in patient understanding about VCT and CTX were identified. CONCLUSION: The results show that it is feasible to routinely implement VCT and CTX for TB patients.

Auditing the new decentralised oral treatment regimens in Malawi.

SETTING: All 44 non-private hospitals in Malawi treating tuberculosis (TB) cases in which oral regimens were used allowing patients during the initial phase to receive directly observed treatment (DOT) from health centres or guardians at home. OBJECTIVES: A country-wide audit of the oral regimens to determine: 1) TB ward bed occupancy rates, 2) patient DOT options, 3) patients' knowledge of treatment and 4) treatment outcomes compared to those obtained with previous treatment regimens. DESIGN: Retrospective data collection using registers and treatment cards. Prospective interviews with patients. Inspections of TB wards. RESULTS: There were 1513 TB beds occupied by 807 (53%) TB patients. Over 50% of 4793 patients registered with different types of TB chose guardian-based DOT. For 266 patients with pulmonary TB the correct knowledge about total duration of treatment (45%), all three DOT options (62%) and the months for giving follow-up sputum (16%), was poor. There were differences in treatment outcomes between TB patients on oral compared with previous regimens. With oral regimens, rates of unknown outcome were high. CONCLUSION: Oral treatment regimens are associated with reduced bed occupancy rates on TB wards. However, rates of unknown outcome are increased, and TB control is therefore weakened.

Resources for controlling tuberculosis in Malawi.

OBJECTIVE: To document resources for controlling tuberculosis (TB) in Malawi. METHODS: We performed a countrywide study of all 43 hospitals (3 central, 22 district and 18 mission) which register and treat patients with TB. To collect data for 1998 on the TB-related workload, diagnostic facilities, programme staff and treatment facilities, we used laboratory, radiographic and TB registers, conducted interviews and visited hospital facilities. FINDINGS: The data show that in 1998, 88,257 TB suspects/patients contributed approximately 230,000 sputum specimens for smear microscopy, 55,667 chest X-rays were performed and 23,285 patients were registered for TB treatment. There were 86 trained laboratory personnel, 44 radiographers and 83 TB programme staff. Of these, about 40% had periods of illness during 1998. Approximately 20% of the microscopes and X-ray machines were broken. Some 16% of the hospital beds were designated for TB patients in special wards, but even so, the occupancy of beds in TB wards exceeded 100%. Although stocks of anti-TB drugs were good, there was a shortage of full-time TB ward nurses and 50% of district hospitals conducted no TB ward rounds. In general, there was a shortage of facilities for managing associated HIV-related disease; central hospitals, in particular, were underresourced. CONCLUSION: Malawi needs better planning to utilize its manpower and should consider cross-training hospital personnel. The equipment needs regular maintenance, and more attention should be paid to HIV-related illness. The policies of decentralizing resources to the periphery and increasing diagnostic and case-holding resources for central hospitals should be continued.

Developing operational research capacity in hospital tuberculosis control officers in Malawi.

SETTING: The National TB Control Programme (NTP) of Malawi. OBJECTIVES: To describe 1) the way in which a generic operational research project was developed and implemented by hospital TB officers (TBOs), 2) the outcome in terms of research work completed, data analysed and papers written up, and 3) the results of the research project. DESIGN: A descriptive study of assessing diagnostic processes in patients labelled as TB suspects who had been admitted to general hospital wards over 4 weeks. RESULTS: A total of 25 TBOs were trained in developing the research protocol: 19 performed satisfactory work, 17 attended an analysis/paper writing workshop and 11 submitted a research paper. The data of five papers were collated. Of 900 hospital admissions, 153 (17%) were TB suspects, of whom 37% were diagnosed with TB, 38% were discharged with another diagnosis and 25% died or absconded during investigations. CONCLUSION: This first attempt at developing a research capacity in hospital TB officers in Malawi was partially successful, and may, through local dissemination and feedback, help to improve the speed of TB diagnosis in hospital in-patients.

Tuberculosis in health care workers in a central hospital in Malawi.

A retrospective study was carried out at Lilongwe Central Hospital, Malawi, to determine 1) the tuberculosis case notification rate in health care workers (HCW) in 2001, and 2) whether NTP guidelines were adhered to in diagnosing TB. Of 571 HCWs, 33 (6%) were notified with TB in 2001, giving a TB case notification rate of 5780/100,000. Patient attendants had higher rates of TB than nurses, ward attendants and doctors, but otherwise there were no significant differences between the HCW categories. NTP diagnostic guidelines were not properly followed, particularly in diagnosing smear-negative TB; in HCWs with smear-negative PTB, 64% had no sputum smears examined. The rate of TB in HCWs in a central hospital in Malawi was high, although lack of adherence to guidelines might have resulted in overdiagnosis.

Preventing recurrent tuberculosis in high HIV-prevalent areas in sub-Saharan Africa: what are the options for tuberculosis control programmes?

Several studies conducted in sub-Saharan Africa have pointed to an increased risk of recurrent TB in patients who are HIV-seropositive. Routine case notification data from the Malawi Tuberculosis Programme, which has improved its registration practices in the last two years, shows that recurrent TB (smear-positive and smear-negative TB) constitutes 9% of total notifications. The objectives of reducing rates of recurrent TB are 1) to complement other interventions to decrease TB incidence rates and transmission of disease, 2) to reduce TB-specific morbidity and mortality and 3) to restore confidence amongst health care staff and patients about the effectiveness of the current TB control strategy. Four possible options for reducing recurrent TB are discussed, and for each option this includes the evidence for effectiveness, current practice and operational considerations. The options are 1) using rifampicin and isoniazid (RH) in the continuation phase of treatment, 2) extending the duration of the continuation phase, 3) providing post-treatment isoniazid prophylaxis to HIV-positive patients who have completed treatment and 4) treating HIV-positive TB patients with highly active antiretroviral therapy (HAART). The last three options all require that TB patients know their HIV serostatus. The authors suggest that this issue of recurrent TB should be considered as one of the important areas for debate and action when considering the dual TB/HIV epidemic.

Decentralisation of treatment for patients with tuberculosis in Malawi: moving from research to policy and practice.

SETTING: Five districts in Malawi. OBJECTIVE: A new oral anti-tuberculosis treatment regimen with different directly observed treatment (DOT) choices in the initial phase of treatment was introduced for new patients in the five districts. The objectives were to determine 1) the site of DOT during the initial phase of treatment, and 2) the effectiveness of the new regimen. DESIGN: Prospective data collection on all tuberculosis (TB) patients registered in a phased approach between 1 July 1997 and 31 December 1998, including site of DOT option in initial phase of treatment, 2-month and 8-month treatment outcomes, 2-month sputum smear conversion in smear-positive pulmonary tuberculosis (PTB) patients and in-patient hospital bed days. RESULTS: There were 6335 new patients: 2671 (42%) with smear-positive PTB, 2211 (35%) with smear-negative PTB and 1453 (23%) with extra-pulmonary TB. The site of the initial phase of treatment was determined in 5790 patients: 1759 (30%) received DOT from guardians, 1465 (25%) from a health centre, 753 (13%) as out-patients from the hospital TB ward and 1813 (32%) remained in hospital. Eight-month treatment completion was 67% for smear-positive PTB patients, 51% for smear-negative PTB patients and 56% for extra-pulmonary TB patients. Two-month outcomes and 8-month treatment outcomes for all out-patient sites of supervision were satisfactory, except that a higher proportion of smear-positive PTB patients under guardian DOT failed to smear convert at 2 months. Over two-thirds of patients received ambulatory treatment out of hospital during the initial phase. CONCLUSION: The new treatment strategy, tested in five districts, was associated with a reduction in hospital bed days and satisfactory treatment outcomes. The results of these studies were vital in helping the National TB Control Programme make an informed decision about phased expansion of the strategy countrywide.
