Setting: Private and public tuberculosis (TB) treatment centers in Lagos State, Nigeria. Objective: To compare adherence of private and public providers of directly observed treatment short course (DOTS) in the Lagos State TB control program, Nigeria (LSTBLCP) with the national TB guidelines. Design: A retrospective review of treatment cards of TB patients managed within the first and second quarter of 2012 in 34 DOTS facilities {23 public, 7 private for profit (PFP), and 4 private not for profit (PNFP)} involved in the private public mix of the LSTBLCP. Results: Of the 1896 treatment cards reviewed, 1524 (80.4%), 132 (7.0%) and 240 (12.6%) were from public, PFP and PNFP DOTS facilities, respectively. About 19%, 25% and none of the patients managed at the public, PNFP, and PFP DOTS facilities were treated in full adherence with the national guidelines respectively. A significantly higher proportion of adults and sputum smear positive TB patients were treated in full adherence with the national guidelines (p < 0.05). Treatment success was associated with full adherence with the national guidelines. Conclusion: There is a need to reorient health care providers in public and private health facilities in Lagos State Nigeria to ensure full adherence with the national TB guidelines.
Tuberculosis (TB) is still a serious public health issue in Nigeria accounting for 46,000 deaths (27 per 100,000 populations) per year [
Adherence to the national TB guidelines is therefore necessary in ensuring that TB patients get quality service irrespective of the service point. Thus, successful treatment could be achieved if the healthcare workers (both public and private medical practitioners) follow the national guidelines for the treatment of TB.
This present study compared adherence of private and public DOTS providers with the national guidelines and the factors associated with adherence with the national guidelines in the Lagos State TB control program, Nigeria.
Lagos state is one of the 36 states in Nigeria and the population is estimated to be 21 million.
Health care services in Lagos State are provided by both the public and private sector. In the public sector, services are organized at primary, secondary and tertiary care. There are 27 secondary, 215 primary and 1984 registered health care facilities (1925 private for profit and 59 private not for profit) in the state.
The Lagos State TB and leprosy control programme (LSTBLCP) commenced operation in 2003 in collaboration with some international organizations. In 2008, private sector participation in DOTS management of TB was introduced. To be eligible, private providers were expected to offer TB services free of cost to patients and undergo training on DOTS management of TB based on the national guidelines [
Based on capacity and interest, private health provider (PHP) were engaged either to refer presumptive TB patients (scheme one), provide DOTS management only (scheme two), serve as microscopy center only or serve both as treatment and microscopy center (scheme three). After training and completion of the necessary formalities, PHP were provided with recording and reporting materials, drugs and other consumables to commence TB services. The patient’s treatment card was one of the recording materials provided to the PHP; it contained patients’ relevant information and also served as a tool to monitor patient’s treatment. Sputum microscopy results, weight measurements and drug intake were recorded on the treatment card.
TB activities in Lagos State were coordinated by the state TB control officer. At the local government level, the state TB control officer was assisted by local government TB supervisors. There are 20 TB supervisors in Lagos State, one in each LGA. They assist the state TB control officer to plan, organize and conduct training programmes, keep an up-to-date and accurate record of activities of TB control activities in the LGA. The supervisors were assisted by TB focal persons in each DOTS facility. Records of patients registered in each DOTS facility were sent to the LGA supervisors monthly and they in turn forward the records of TB patients managed in the LGA to the state control officer quarterly.
The DOTS facilities at the primary health centers (PHCs) were coordinated by Community Health Officers and nurses whereas the medical officer coordinates DOTS facilities at the secondary, tertiary, private and the military health facilities. Any health care worker could initiate treatment for smear positive TB patients; however children and presumptive TB clients with smear negative results were referred to health facilities manned by doctors for diagnosis.
Management of TB at PHP facilities is free; however they were allowed to charge for consultation and service charge for sputum AFB microscopy because reagents and consumables for sputum AFB were freely supplied by the LSTBLCP. The PHP could also charge for investigations such as chest X-ray, erythrocyte sedimentation rate (ESR), etc. required to diagnose smear negative patients. The duration of treatment was eight months. The treatment regimen consisted of two months intensive phase of Rifampicin, Isoniazid, Pyrazinamide and Ethambutol as fixed dose combination and six months continuation phase of Rifampicin and Isonizid as fixed dose combination. Drugs were prescribed based on patient’s weight and recorded on the treatment card.
According to the national guidelines, each presumptive TB patient were offered HIV testing. The HIV rapid test kit used in accordance with the national HCT policy was Determine (determine HIV-1/2 Alere Determine™, Japan 2012) and Uni-Gold™ (Trinity Biotech PLC, Wicklow, Ireland 2013) in parallel algorithm. A concordance result was regarded as positive. In the event of discordant result, STAT-PAK® was used as tie breaker. TB/HIV co-infected patients were offered CPT along with anti-TB drugs and commenced on ART within 8 weeks of anti-TB medications.
At the end of 2011, the LSTBLCP had 130 TB treatment facilities offering DOTS services. Of these, 99 were public and 31 private health care facilities (20 Private for Profit (PFP) and 11 Private not for Profit (PNFP) or missionary hospitals).
A retrospective review of patients’ treatment cards managed for pulmonary TB during the first and second quarter of 2012 was conducted.
A sampling frame of 130 DOTS facilities provided by the Lagos state programme officer (99 public and 31 private DOTS facilities) was used to select, 34 DOTS facilities (23 public, 7 PFP and 4 PNFP DOTS facilities) that served as both microscopy and treatment centers and were involved in DOTS programme for at least 2 years prior to the study. All treatment cards of patients managed for pulmonary TB during the first and second quarter of 2012 in the selected DOTS facilities were assessed for adherence with the national guidelines [
Adherence of public and private DOTS providers to the national guidelines was based on the following [
・ Performance of smear microscopy before DOTS treatment.
・ HIV test done for patients.
・ Specification of patients treatment category.
・ Weight measurement of patient before commencement of treatment.
・ Weight measurement at least 3 times (2nd, 5th and 7th month of treatment).
・ Three follow up sputum results at 2nd, 5th and 7th month of treatment.
・ Correct recording of sputum results.
・ Correct charting of drugs.
・ Correct dosages in line with the weight of the patient.
・ Correct filling of treatment cards.
・ Specification of the treatment outcomes.
In this study, performance of the entire task stated above was regarded as full adherence to national guidelines while incomplete performance was regarded as partial adherence.
・ Treatment success was defined as the sum of the cases that were cured and that completed treatment [
Data was analysed using the Statistical Package for Social Sciences (SPSS) version 19. Mean and standard deviation were calculated for numerical data while percentages were calculated for both numerical and categorical data. Chi square and Fishers’ exact test was used to compare categorical data as appropriate. The confidence interval was set at 95% for all statistical tests. Microsoft excel was used to draw charts.
As data for this study were retrieved from secondary data routinely collected by the LSTBLCP, no ethical clear- ance was required.
Treatment cards of 1896 TB patients were reviewed out of which 1524 (80.4%), 132 (7.0%) and 240 (12.6%) were from the public, PFP, and PNFP DOTS facilities respectively (

sputum (54.2% vs 52.4%) (p < 0.05) during the entire treatment duration. However, more of the patients treated at the public DOTS facilities did weight measurements (53.1% vs 41.4%) and had the correct dosage of TB drugs based on weight (90.6% vs 71.0%) compared with those managed at the private DOTS facilities (p < 0.001). A higher proportion of patients managed at the private DOTS facilities interrupted treatment (22.8% vs 24.7%) compared with those managed at the public DOTS facilities (p = 0.437).
Recording of sputum smear results (7.7% vs 14.0%), treatment outcome (43.8% vs 53.8%) and filling of the treatment cards (22.6% vs 32.8%) were poorly done for significantly higher proportion of patients managed at the private DOTS facilities compared with those treated at the public DOTS facilities as shown in
One of the goals of the public private mix (PPM) for TB is to provide rational and standardized treatment to TB patients especially those managed at the private sector, thereby reducing the spread of TB within the community and emergence of multi drug resistance TB. Routinely, the NTBLCP and the LSTBLCP organizes training and retraining programs for health care workers at the public DOTS facilities and private sector involved in the PPM. This training is expected to facilitate adherence with the national guidelines. This study however shows that the proportion of patients managed in full adherence with the national guidelines at the public and private DOTS facilities was low. Particularly striking was the fact that none of the patients managed at the PFP facilities were managed in full adherence with the national guidelines. Studies from Nigeria and other high TB burden countries have shown that private practitioners and health care workers from the public sector do not comply with the National Tuberculosis Programme (NTP) [
Many reasons have been shown to be responsible for the poor adherence of health care workers at the TB treatment centers. Some studies found that insufficient knowledge of health workers at the public and private

sector about the guidelines was responsible for the poor adherence [
Health care workers are usually trained before they were allowed to provide TB services. However, maintaining trained staff has been a major challenge in the TB programme especially in a cosmopolitan city like Lagos. The high staff turnover experienced in the private sector maybe due to poor job satisfaction and/or job insecurity. In addition, the regular redeployment and poor distribution of trained staff within the public health sector is a cause of concern in the sustainability of public health programmes in developing countries like Nigeria [
Sputum microscopy is the main diagnostic tool for pulmonary tuberculosis and all presumptive TB clients should have sputum microscopy as the first diagnostic tool. In this study almost all the patients managed at the public and private DOTS facilities did sputum smear microscopy before commencement of anti-TB treatment. This is similar to findings from studies from Nigeria and elsewhere [
There is a strong synergy between TB and HIV/AIDS and the WHO recommends HIV testing for TB patients to reduce the burden of TB/HIV [
One of the goals of the NTBLCP was to increase the success rate of TB patients [
The study was a retrospective review of treatment cards and as such did not consider other factors such as training of health personnel at DOTs facilities, availability laboratory equipment and supplies and provision of logistic necessary to track patients lost to follow which could affect adherence to the national guidelines.
Majority of the patients treated at the public and private DOTS facilities in Lagos State were not treated in full adherence with the national guidelines. There is an urgent need for the LSTBLCP to reorient health care providers in public and private health facilities to ensure full adherence with the national guidelines on the management of TB in Nigeria.
