Objective: To identify the most effective form of contact, as a possible intervention to reduce absenteeism in consultations of children with suspected or confirmed pulmonary tuberculosis.
Methods: A randomized clinical trial was conducted with prospective data collection, between March 2017 and February 2018. Patients were randomized into three groups to be reminded about the appointment: telephone contact, SMS or WhatsApp, or no intervention. A convenience sample was obtained, with a significance level of 5%.
Results: 78 children were included, with a median age of four years old (zero to 14); 59.0% of them were in treatment for a latent infection and 6.4% had active tuberculosis. Among the 78 children, 74.4% lived in Curitiba (Sourhern Brazil); 62.8% lived with both parents; 38.5% of the parents had formal employment and 47.4% of the mothers were housewives; 50.8% of the fathers and 55.7% of the mothers had more than nine years of schooling. In 78.2% of the families, per capita income was up to 0.5 minimum wages; 27.3% were enrolled in social programs; 28.2% lived in homes provided by the government. There was a total of 238 interventions made: 85 (35.7%) by telephone contact, 78 (32.8%) by text message (WhatsApp was 97.2% of these) and 75 (31.5%) had no further contact. There was no statistical difference among the sociodemographic and cultural characteristics studied. The absenteeism rate was 24.0% and the abandonment rate was 16.7%. Giving a reminder to the patient's guardian prior to the consultation, regardless of the intervention (p=0.021) and specifically by WhatsApp message (p=0.032) was associated with no absenteeism, though it was not associated with abandonment of the treatment.
Conclusions: Using new tools, such as WhatsApp, to remind guardians of appointments reduces absenteeism. Consequently, it may lead to a reduction in abandoning treatment and it may improvetreatment outcome of children with a tuberculosis infection or disease.
Objetivo:: Identificar a forma mais efetiva de contato, como possibilidade de intervenção, para diminuir o absenteísmo em consultas de crianças com suspeita ou com tuberculose pulmonar.
Métodos:: Ensaio clínico randomizado com coleta de dados prospectiva, entre março de 2017 e fevereiro de 2018. Os pacientes foram aleatorizados em três grupos para relembrar a consulta: contato telefônico; mensagens curtas (SMS) ou WhatsApp; e nenhuma intervenção. Amostra de conveniência, com nível de significância de 5%.
Resultados:: Incluídas 78 crianças, mediana de idade quatro anos (zero a 14); 59,0% em tratamento para infecção latente e 6,4% com tuberculose ativa; 74,4% moravam em Curitiba, Paraná; 62,8% residiam com ambos os pais; 38,5% dos pais possuíam emprego formal e 47,4% das mães eram do lar; 50,8% dos pais e 55,7% das mães possuíam mais de nove anos de estudo; em 78,2% das famílias a renda per capita foi de até 0,5 salário mínimo; 27,3% estavam inscritas em programas sociais; e 28,2% residiam em casa cedida. Foram 238 intervenções: 85 (35,7%) por contato telefônico, 78 (32,8%) por mensagem de texto (WhatsApp 97,2%) e 75 (31,5%) sem nenhum contato adicional. Nas características sociodemográficas e culturais estudadas não houve diferença estatística. O absenteísmo foi de 24,0% e o abandono, de 16,7%. Lembrar o responsável previamente à consulta, independente da intervenção (p=0,021) e especificamente por mensagem por WhatsApp (p=0,032) foi associado ao não absenteísmo, porém não associado ao abandono.
Conclusões:: O uso de novas ferramentas, como o aplicativo WhatsApp, pode reduzir o absenteísmo, diminuir a possibilidade de abandono no seguimento e melhorar o desfecho do tratamento de crianças com tuberculose, seja a infecção ou a doença.
