Evaluation of the Impact of a Mass Media Campaign on Periodontal Knowledge among Iranian Adults: A Three-Month Follow-Up.

ABSTRACT:

Objectives

This study aimed to evaluate the impact of a national media campaign to promote oral health and periodontal knowledge among adults after a three-month follow-up.

Methods

We conducted a population-based study of adults aged 18 to 50 years using a stratified multi-stage sampling method in Tehran, Iran in 2011. The campaign included an animation clip about periodontal health and disease telecast on national TV for ten consecutive days. We used an instrument to assess the effect of the campaign at baseline, immediately after the campaign and after a three-month follow-up. A total of 543 participants responded at baseline and immediately after the intervention, and 294 were interviewed at the three-month follow-up assessment (response rate: 54.1%). We assessed each participant's periodontal knowledge score, calculated as a sum of correct answers, and the change in their score following the campaign. We then used a five-item questionnaire to evaluate the participants' opinion of the success of the campaign. We used descriptive statistics and generalised estimating equations (GEE) analysis to conduct the statistical analysis.

Results

The mean score for knowledge improvement from baseline to immediate post-intervention evaluation was higher among those who saw the campaign (0.61) than among those who did not (0.29); the corresponding figures from immediate evaluation to three-month follow-up were -0.17 and 0.15, respectively. Adjusting for baseline values, the GEE analysis demonstrated that improvement in the mean score of post-campaign knowledge associated significantly with age, education and seeing the campaign. Significant interaction between the time since seeing the campaign and whether the participant saw it (p < 0.001) revealed that the mean difference in the knowledge score between the groups who did and did not see the campaign was 0.4 at the immediate evaluation and -0.04 at the three-month follow-up. The participants received the campaign well in terms of being appealing (91.4%), worth bearing in mind (83.4%) and containing valuable information (80.3%).

Conclusions

Our findings indicate that a population-based media campaign promoting oral health and periodontal knowledge among adults had a positive short-term impact, although the effect seemed to plateau after three months.

Project description:BackgroundMost patients including health care workers (HCWs) survived the coronavirus disease 2019 (COVID-19), however, knowledge about the sequelae of COVID-19 after discharge remains limited.MethodsA prospectively observational 3-month follow-up study evaluated symptoms, dynamic changes of severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) IgG and IgM, lung function, and high resolution computed tomography (HRCT) of survivors of COVID-19 after discharge at Wuhan Union Hospital, China.ResultsSeventy-six survivors (55 females) with a mean age of 41.3 ± 13.8 years were enrolled, and 65 (86%) were HCWs. A total of 69 (91%) patients had returned to their original work at 3-months after discharge. Most of the survivors had symptoms including fever, sputum production, fatigue, diarrhea, dyspnea, cough, chest tightness on exertion and palpitations in the three months after discharge. The serum troponin-I levels during the acute illness showed high correlation with the symptom of fatigue after hospital discharge (r = 0.782; P = 0.008) and lymphopenia was correlated with the symptoms of chest tightness and palpitations on exertion of patients after hospital discharge (r = -.285, P = 0.027; r = -.363, P = 0.004, respectively). The mean values of forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC), FEV1/FVC, total lung capacity and diffusion capacity were all normal (> 80% predicted) and lung HRCTs returned to normal in most of the patients (82%), however, 42% of survivors had mild pulmonary function abnormalities at 3-months after discharge. SARS-CoV-2 IgG turned negative in 11% (6 of 57 patients), 8% (4 of 52 patients) and 13% (7 of 55 patients), and SARS-CoV-2 IgM turned negative in 72% (41 of 57 patients), 85% (44 of 52 patients) and 87% (48 of 55 patients) at 1-month, 2-months and 3-months after discharge, respectively.ConclusionInfection by SARS-CoV-2 caused some mild impairments of survivors within the first three months of their discharge and the duration of SARS-CoV-2 antibody was limited, which indicates the necessity of long-term follow-up of survivors of COVID-19.

Project description:ObjectiveTo explore patient characteristics, resource use, and costs related to different episodes of care (EOC) in Finnish health care.DesignData were collected during a three-month prospective, non-randomized follow-up study (Effective Health Centre) using questionnaires and an electronic health record.SettingThree primary health care practices in Pirkanmaa, Finland.SubjectsAltogether 622 patients were recruited during a one-week period. Inclusion criteria: the patient had a doctor's or nurse's appointment on the recruiting day and agreed to participate. Exclusion criteria: patients visiting a specialized health guidance clinic for pregnant women, children, and mothers.Main outcome measuresPatient characteristics, resource use, and costs based on the ICPC-2 EOC classification.ResultsOn average, the patients had 1.22 EOCs during the three months. Patient characteristics and resource use differed between the EOC chapters. Chapter L, "Musculoskeletal", had the most episodes (17%). The most common (8%) single EOC was "upper respiratory infection". The mean cost of an episode (COE) was €389.56 (standard error 61.11) and the median COE was €165.00 (interquartile range €118.46-288.56) during the three-month follow-up. The most expensive chapter was K, "Circulatory", with a mean COE of €909.85. The most expensive single COE was in chapter K, €32 545.56. The most expensive 1% of the COEs summed up covered 36% of the total COEs.ConclusionPatient characteristics, resource use, and costs differed between the ICPC-2 chapters, which could be taken into account in service planning and pricing. Future studies should incorporate more specific diagnoses, larger data sets, and longer follow-up times. Key points The most common episodes were under the ICPC-2 "Musculoskeletal" chapter, but the highest mean and single-episode costs were related to the "Circulatory" chapter. The mean (median) cost of episodes that started in primary care was €390 (€165) during the three-month follow-up. Patient characteristics, resource use, and costs differed significantly between the ICPC-2 chapters. The most expensive 1% of the episodes covered 36% of the total costs of all the episodes.
