PROBLEM: Voluntary counselling and testing (VCT) data from the registered sites in Kenya have been fraught with challenges, leading to insufficient statistics in the national office for planning purposes. An exercise was carried out to determine the barriers to the flow of data in VCT sites in Kenya.
APPROACH: A record-based survey was conducted at 332 VCT sites in Kenya. Data from on-site records were compared with those in the national office. The exercise was conducted in 2004 between 5 September and 15 October.
LOCAL SETTING: All registered VCT sites in Kenya.
RELEVANT CHANGES: After the exercise, various measures to enhance VCT data collection and reporting were implemented. They include the provision of a uniform data collection and reporting tool to all the districts in the country, the strengthening of a feedback mechanism to update provinces and districts on their reporting status and increased support to the data component of the national quality assurance for VCT.
LESSONS LEARNED: Periodical field visits by the national officials to offer on-the-job training about data management to data collectors and to address data quality issues can dramatically improve the quality and completeness of VCT reports. The perceived relevance of the data and the data collection process to those working at the sites is the critical factor for data quality and timeliness of reporting.
PPROBLÈMATIQUE: Le recueil de données à partir des sites de conseil et de dépistage agréés du Kenya seffectue très difficilement, doù une insuffisance des statistiques réunies au niveau national à des fins de la planification. Un exercice a été pratiqué pour identifier les obstacles sopposant à la circulation des données au niveau des sites de conseil et de dépistage volontaire kenyans.
DÉMARCHE APPLIQUÉE: Une enquête a été menée à partir des dossiers tenus par 332 sites de conseil et de dépistage volontaire kényans. Les données tirées des dossiers ont été comparées avec celles dont dispose le Bureau national des statistiques. Lexercice a été réalisé en 2004, du 5 septembre au 15 octobre.
CONTEXTE LOCAL: Tous les sites de conseil et de dépistage volontaire agréés du Kenya.
MODIFICATIONS INTÉRESSANTES APPORTÉES: A lissue de lexercice, diverses mesures visant à améliorer la collecte et la transmission des données par ces sites ont été mises en place. Parmi ces mesures, figuraient lintroduction dun outil de collecte et de transmission homogènes des données dans tous les districts du pays, le renforcement du mécanisme dinformation en retour, destiné à renseigner les provinces et les districts sur leur situation en matière de notification, et lapport dun soutien accru à la composante Qualité des données du système national dassurance de la qualité sappliquant au conseil et au dépistage volontaire du VIH.
ENSEIGNEMENTS TIRÉS: Il est possible daméliorer considérablement la qualité et la complétude des notifications transmises par les centres de conseil et de dépistage en délégant périodiquement des spécialistes nationaux dans ces centres afin de former sur place les personnes chargées de recueillir les informations à la gestion des données et de résoudre les problèmes de qualité affectant ces données. La perception par les personnes travaillant dans ces centres de lintérêt des données quils recueillent et du processus de collecte est déterminante pour la qualité de ces données et leur notification en temps utile.
PROBLEMA: Los datos sobre el asesoramiento y pruebas voluntarias (APV) obtenidos en los centros registrados en Kenya presentan muchas deficiencias, lo que impide que la oficina nacional disponga de estadísticas suficientes a efectos de planificación. Se emprendió un trabajo para determinar los factores que obstaculizaban el flujo de los datos en los centros de APV en Kenya.
MÉTODOS: Se llevó a cabo un estudio de los registros de 332 centros de APV de Kenya. Los datos de los registros in situ se compararon con los de la oficina nacional. El trabajo se realizó en 2004, entre el 5 septiembre y el 15 de octubre.
CONTEXTO LOCAL: Todos los centros de APV registrados en Kenya.
CAMBIOS DESTACABLES: Terminado el trabajo se implantaron diversas medidas para mejorar la recopilación y notificación de los datos de APV. Entre ellas cabe citar el suministro de un instrumento de recogida y notificación de datos uniforme a todos los distritos del país, el refuerzo de un mecanismo de retroinformación para poner al día a las provincias y los distritos acerca de su situación en cuanto a la notificación, y un mayor apoyo al componente de datos del sistema nacional de garantía de la calidad para el APV.
EXPERIENCIA ADQUIRIDA: Las visitas periódicas al terreno a cargo de funcionarios nacionales para ofrecer a los encargados de recoger los datos formación en el empleo sobre la gestión de los datos y para abordar aspectos de la calidad de los mismos permiten mejorar extraordinariamente la calidad y la completud de los informes sobre el APV. La importancia asignada a los datos y al proceso de recopilación de datos por quienes trabajan en los centros es el factor más decisivo para asegurar la calidad de los datos y la puntualidad de las notificaciones.
The Government of Kenya, with other stakeholders, developed a national HIV/AIDS strategic plan1 that identifies strategies to alleviate the spread of HIV/AIDS whose prevalence is estimated at 6.7%.2 One of the key strategies since 2001 has been the establishment of voluntary counselling and testing (VCT) services, which have spread rapidly throughout the country.3,4 Early in 2001 a common national VCT data collection form was piloted by stakeholders and adopted for national usage.5
VCT sites are all registered with the national AIDS and sexually transmitted infection (STI) control programme (NASCOP) and supervised annually, during which time the quality of the on-site laboratory and counselling room records are assessed. Registered sites, whether governmental or nongovernmental, are issued with a unique site code, based on both province and district.4,5 All sites make monthly returns to their district AIDS and STI coordinator (DASCO), and are issued with free test kits from the government in return for data. In theory the returns are passed up a chain for final collation at NASCOP. At the time of this exercise, there were 332 registered sites.
Many of the donor-supported sites follow a parallel reporting system where data are channelled through their internal mechanism to their main offices. Key among the donor sites are the Centers for Disease Control and the Liverpool VCT (an independent nongovernmental organization in Kenya), which represent fewer than 30% of the sites but around 90% of their data are available in NASCOP.
In Kenya, the national VCT programme uses four models that are integrated, stand-alone, community-based and mobile.3,5 The integrated sites are located within the grounds of a health facility, whereas stand-alone sites are usually not associated with medical institutions. VCTs in the community-based approach are integrated into other social services or are implemented as the core activity, whereas the mobile approach provides outreach to remote or hard-to-reach areas.
A comprehensive national database is crucial for government planning and budgeting purposes, including the sourcing of test kits, training of VCT counsellors and counsellor supervisors, and the planning of treatment programmes. VCTs have a potential to integrate family planning and other services as well as to provide a point of entry into the health-care system for people who are found to be HIV positive. Owing to the rapid increase of VCT sites in Kenya, there has been a challenge with regard to data collection and management. NASCOP has not been able to receive proper and up-to-date data about the client flow at these sites, posing a challenge to the national VCT database. We therefore set out to determine the completeness of the on-site records, follow up missing data for the national VCT database and determine the barriers to the flow of data in VCT sites in Kenya.
In this exercise, we used an evaluative operations research approach that was non-experimental. In our sample, all registered sites were surveyed quarterly for missing data. We adopted a record-based quantitative survey and a semi-structured interview of key informants to explore opinions about the causes of delays in data handling. All registered sites were surveyed for missing data. Interviews were conducted with key informants, such as counsellors, DASCOs and provincial AIDS and STI coordinators (PASCOs) at sites where delays in data submission were identified.
Two teams of four members were selected and worked simultaneously in different provinces collecting data between 5 September 2004 and 15 October 2004. There was a short training session for data collectors before the start of the exercise; this included how to survey the opinions of key informants with regard to delayed submission of reports, completion of the quarterly reports and the new data collection tool. The role of the data collector entailed collecting missing data from the logbooks, pretesting a new data collection tool and surveying opinions among key informants with regard to delayed submission of data reports. Collection of data was, firstly, through visiting the PASCO and DASCO offices for any relevant VCT reports from registered sites recognized by NASCOP. Failure to get up-to-date records in these offices led the teams to visit the affected sites. Data were collated from September 2001 (shortly after the scale-up of VCT began) until the second quarter of 2004. For the sites with missing data in the central database (monthly and quarterly) or those with reports that did not disaggregate their data by gender, the teams manually extracted this information from the on-site logbooks and client forms. Data were analysed using simple descriptive statistics in Microsoft Excel.
Of the existing 332 sites officially registered in the second quarter of 2004, 298 (89.76%) had some missing records and their statistics were updated through this exercise. All the sites had completed client forms and logbooks, which were used to retrieve the missing data. In the event of a shortage in the required VCT stationery, the sites improvised a data collection tool. Existing data at the beginning of the survey showed 193 959 client records in the national database for the period between the second quarter of 2001 and the second quarter of 2004. On-site records revealed a further 220 944 records. After the exercise there were more than twice as many HIV positive individuals identified than were originally estimated. Details are given in Table 1.
Interviewees perceived that data were less likely to reach the national database on time from sites that were remote and rural; remote sites refer to those that were sparsely distributed and hard to reach. In the integrated sites, staff shortages arose because health workers had more urgent medical problems to attend to and could not devote enough time to VCT. As integrated sites experienced more staff shortages than the stand-alone sites, members of staff reported they had less time to submit data. Four different types of data collection forms were found to be in use in the VCT sites: monthly and quarterly report forms; a monthly summary sheet used in some sites for the purposes of quality assurance exercises; a donors monthly summary tool and tools developed by DASCOs for their own summaries. The monthly summary sheet, which does not segregate the tested clients by sex, was widely used. No data tracking system was in place to identify where delays occurred.
The presentation of data from the VCT sites in Kenya has been complicated by the use of differing data collection tools. The updating of the national VCT database in NASCOP is bound to be enhanced by the use of one agreed simple data collection tool. In order to design a standard data collection tool to yield high quality usable information careful planning is needed, as is an effective method of distribution.6
Service delivery is a two-way procedure that entails collection of information by the relevant authorities and provision of feedback. NASCOP should develop a feedback mechanism on the performance of the VCTs and this should increase the submission of reports. Enabling VCT sites to effectively communicate priorities, expectations, participate in shared decision-making and to evaluate the relative success of their operations is a positive attribute. Such participation should lead to a more comprehensive appreciation of the challenges and management solutions.7
The availability of timely collected data in the national office is important for the planning of activities. By linking VCT data to other national monitoring and evaluation systems such as anti-retroviral, prevention of mother-to-child transmission, etc., information will be provided that is split by gender, age, region, prevalence of HIV, etc. otherwise called disaggregation in one comprehensive tool.8,9 It is envisaged that an up-to-date national database will facilitate better planning and links to treatment programmes supported by NASCOP. Furthermore, the integration of various reporting mechanisms in a system is crucial for timely and up-to-date records required for planning; hence the need for a better integration of donor reporting with the national reporting of VCT data.
In the Kenyan context, provision of VCT services and the number of sites reporting their data quarterly to NASCOP have increased tremendously since the inception of the exercise. To sustain the timely reporting of VCT data, all stakeholders are required to implement collaboratively a systematic integration of guidance, capacity building and assistance.10 The outcome of this could be used to identify both good and bad (acceptable and unacceptable) trends in the performance of VCT centres.11
HIV/AIDS remains the greatest challenge to development in sub-Saharan Africa and VCT is a key intervention measure within the comprehensive care programme. While significant progress has been made in developing the monitoring and evaluation systems in health care in resource-poor countries, the challenge of collecting data required for planning persists.
With the VCT data from Kenya, this paper shows that relevance of the data and the data collection process to the facility are critical to ensure data quality and timeliness of reporting. Furthermore, we demonstrate the importance of a holistic approach that integrates all the stakeholders into the development and planning of the national monitoring and evaluation systems.
We thank the National AIDS and STI Control Programme, the Global Fund, DfID and Futures Group Europe-Kenya for providing the financial and logistical support that enabled the national VCT data collection exercise to take place.
